Technical Field

The present invention relates to a hawse hook for a trampoline fixture and also to a fixture for inserting a rebounding mat of a trampoline into a frame assembly of the trampoline.

Background

Trampolines, such as miniature trampolines for sports and therapeutic purposes, require a suitable oscillating fixture system to secure and hold or mount the rebounding mat. In the miniature trampoline according to DE 10226707, the rebounding mat is preferably held by a combination of resilient elements and hawse hooks rather than by steel springs.

WO 2017/191144 a1 of the applicant describes a series of different hawse hooks in which at the free end an elastic element with a clamping element can be mounted, wherein the flexible strip element of the rebound pad is guided onto the opposite side of the hawse hook and attached thereto.

Disclosure of Invention

The fundamental problem with small trampolines is the compromise between the smallest possible outer diameter of the surrounding frame, the largest possible diameter of the rebounding mat and the damping/vibration determined by the length of the spring stroke of the resilient element.

Starting from the above prior art, the object of the present invention is to indicate an improved hawse hook with which the usable length of the spring elements is optimized for a larger spring travel without thereby reducing the diameter of the usable movement area of the mattress. Furthermore, it is an object of the invention to protect trampoline users from the hawse hooks and underlying securing systems in the event of tripping of a small trampoline. At the same time, the system should be easy to maintain and to replace the individual elastic elements and the hawse hooks. Furthermore, the new solution should achieve significantly better oscillation.

To this end, an anchor hook is provided for fixing the rebounding mat to the trampoline frame by using two elastic elements and at least one flexible strap element, wherein the anchor hook has a housing with four receivers, wherein each elastic element has two free ends, each free end having a clamping element enlarging the circumference of the elastic element, wherein the clamping elements of the (two) elastic elements can be inserted into said each receiver. The fluke has a fluke body which is closed in a peripheral direction transversely to the fixing direction, wherein in each case the two receiving pieces are separated from the center by a receiving cavity in the fluke body, through which the clamping element can pass. The fluke has two terminals, each of which can be inserted into a respective receiving cavity and has rounded covers pointing around away from the fluke housing and oriented towards each other.

In practical tests, it was also found that the new clamping solution has a significantly better service life, i.e. the elastic element is able to withstand more than 50% to 600% of the vibration cycles compared to other solutions, and therefore the customer benefit is above all to increase the sustainable quality of the oscillations (health promoting impulses) and the durability of the elastic element (use costs).

The hawse hooks are closely arranged to each other in a circle and the spoiler forms a visual and tactile warning sign for the user towards the center of the mat. They signal the user visually and by contact with the foot, clearly indicating the end of the movement area. The spoiler is slightly inclined towards the area of movement ensuring that the fabric edge area rises gracefully in this area and lies neatly on the hawse hook.

According to tests, the use of rubber belts without conventional deflection on the cushion side leads to a significantly higher durability in the range of millions of load cycles compared to conventional fastening methods (e.g. known methods), such as the methods proposed by the Bellicon company in DE 202007019487U 1 or US 2010/0009812 a 1. In this solution, a straight rubber band is guided around the frame tube starting from the fixing body and then enters straight into the second receiving position of the receiving body. A fixing element is provided on the end of the rubber cable, which element can engage more strongly when the tensile load increases. The attachment ring is fixed as a flexible band element in the body of the fixing element, not behind the fixing element, thereby shortening the installation length between the last seam towards the centre of the mat with which the ring is stitched to the mat and the starting point at the hawse hook where the elastic element (rubber cable) turns into a free stretch towards the trampoline frame. Furthermore, this compact shape improves retention, particularly by the clamping ring rather than wrapping it around the web portion. The interruption of the ring grip in the middle area leads to a reduction of the installation space, making the height higher, so that an alligator clip can be inserted in the central position between the two fixing points for the left and right rings of rubber cables.

The curved spoiler allows the cushion edge or cushion periphery to deflect slightly beyond the anchor. The configuration of the hawse hook as a closed box (receiving box) together with the spoiler provides a more compact and gentler shape that does not cause contact injuries due to tripping. The resulting edges/loops of adjacent hawse hooks with spoilers form a prominent visual mark to demarcate a safe area of movement.

In a basic design, the fluke securing the rebounding mat to the trampoline frame via the two resilient elements and the at least one flexible strap element includes a fluke housing with four receiving members. Into which a resilient element of a clamping element with an enlarged circumference of the resilient element is inserted. The fluke then has at least one receiving chamber located between the two receiving parts, and an end fitting (also referred to as spoiler) assigned to the receiving chamber. The terminal can be introduced into the housing cavity and has a rounded cover pointing away from the fluke housing and towards the flexible band element to be centrally arranged and optically and tactilely marking the user with the edge of the rebound pad.

Two receiving chambers for two end pieces with rounded caps facing the flexible band element may be provided in the shank of the fluke, the rounded caps being centered, i.e. one spoiler above and one spoiler below the band element.

The receiving cavity may be a through hole and the end fitting preferably has a form fitting attachment to the fluke body. This may be a hook which engages with an edge of the shank of the chain. The receiving space can also be a blind hole or can have an opening, for example in the form of a cross recess, through which a knob can be pressed in as a retaining element.

Advantageously, if the fluke body of the fluke is closed in a peripheral direction transverse to the fixing direction, the spoiler can be used in a very small installation space. It also has greater structural integrity.

Then, two receiving pieces are arranged in the center of the receiving cavity of the fluke body and a common cavity is formed, wherein the clamping element can pass through the receiving cavity and be moved laterally into one of the receiving pieces. The receiving space therefore also serves as a passage space for the clamping element of the spring element, so that the necessary installation height is further reduced.

An insertion groove for the flexible strap element is provided centrally between the upper and lower receiving part, wherein the strap element forms a loop with a retaining rod that can be placed therein, wherein the insertion groove tapers on the loop side towards the flexible strap element that has been connected together, such that the loop in which the retaining rod can be inserted is located in the region of the anchor hook body, advantageously in the region of the anchor hook body in which the loop in which the retaining rod can be inserted is located in a force-fitting manner when tension is applied. Thus, the loop already ends inside the fluke body, instead of behind the fluke body, thereby saving further distance in the radial direction, which is advantageous for the cable length of the elastic element.

The upper and lower receivers may be tapered in the direction of the elastic element forming the loop, so that the clamping element is located in the region of the fluke body, advantageously in a force-fitting manner when tension is applied. Here, in the radial direction of the trampoline, a distance is saved on the cable element side, so that both tensioning elements (e.g. the strap element and the cable) are located in the fluke body together with their fixing bodies (i.e. the retaining rod and the clamping element).

The tapered wall may be oriented substantially perpendicular to the plane of the flexible strap member. They may also be oriented parallel to the plane of the flexible tape element, wherein in an embodiment with a common receiving cavity, on one side they are only partly formed by shoulders forming a transverse central termination.

A securing system for securing a rebounding mat to a trampoline frame, wherein the rebounding mat includes a plurality of flexible strap members connected thereto, and a plurality of hawse hooks corresponding to the number of flexible strap members according to one of the embodiments described herein is used.

A trampoline having a rebounding mat and a trampoline frame further comprises a securing system as described herein by which the rebounding mat is suspended in the trampoline frame.

Finally, the method of securing the rebounding mat to the trampoline frame uses the steps of:

i) there is provided a fixation system as described herein,

ii) passing the flexible strap member through the central insertion slot in the hawse hook to laterally insert the retaining rod into the loop-shaped opening of the flexible strap member and to pull the flexible strap member back into the insertion slot,

iii) surrounding the resilient element around a portion of the trampoline frame,

iv) passing the first clamping element of the first elastic element through the receiving cavity of the hawse hook and moving the elastic element together with the transverse clamping element laterally into the transverse receiving member,

v) passing the second clamping element of the first elastic element through the housing cavity of the hawse hook and moving the elastic element laterally with the transverse clamping element into the transverse receptacle on the same side of the housing cavity,

vi) passing the first clamping element of the second resilient element through the receiving cavity of the hawse hook and moving the resilient element together with the transverse clamping element laterally into the remaining opposite transverse receiving member,

vii) passing the second clamping element of the second elastic element through the receiving cavity of the hawse hook and moving the elastic element together with the transverse clamping element laterally into the remaining opposite transverse receiving member,

viii) fixing the two clamping elements of the two hawse hooks in the designated accommodation spaces of the hawse hooks in order to clamp the rebounding mat in the trampoline frame.

The above description of embodiments generally refers to two elastic elements per fluke, the same or similar advantages also arising from a single elastic element per fluke, since the band element and/or the insertion slot of the clamping element with the receiving member can here also be connected by a single elastic element with one fluke and two receiving members.

Further embodiments are indicated in the dependent claims.

Detailed Description

Fig. 1 shows a perspective view of an embodiment of the fluke 10 with two elastic elements 20 and a flexible strap element 50, seen towards the side of the elastic elements 20, while fig. 2 shows a different perspective view of the embodiment according to fig. 1, seen from the flexible strap element 50.

Each elastic element 20 has a rubber cable 21, and clamping elements 30 are arranged on both free ends of the rubber cable 21. The clamping element 30 is described in more detail in connection with the other figures. For the function of the fastening device comprising the fluke 10, the elastic element 20 and the strap element 50, it is important that the elastic element is folded back 180 ° to half its length and that the two clamping elements 30 can be inserted into the respective receivers 14 of the fluke 10. These receiving members 14 are described in more detail in connection with other figures. The body 11 of the fluke 10 is rectangular and closed with a circular piece, seen in the longitudinal direction of the inserted elastic element 20 and the strap element 50. Furthermore, in fig. 1 and 2, the two spoilers 12 are inserted in the direction of the belt member 50 and are bent over each other in the direction of the belt member 50 from being flush with the upper and lower surfaces of the main body 11, and thus surround the belt member and cover a portion thereof. The belt element 50 is attached in a known manner to a rebound pad, in particular sewn thereto, wherein the rebound pad (shown below) can be arranged to the area of the front edge of the spoiler 12. Each spoiler has a catch 13, the catches 13 being used to secure the spoiler in the cavity of the main body 11 of the hawse hook; the parting plane between the body 11 and the spoiler 12 serves as a mating end surface.

Figure 3 shows a perspective front view of the (empty) hawse hook of figure 1; FIG. 4 shows a perspective rear view (filled form) of the hawse hook as in FIG. 2; figure 5 shows a rear view of the hawse hook looking towards figure 3; figure 6 shows a front view of the fluke looking towards figure 4; FIG. 7 shows a side view of the fluke of FIG. 1; finally, fig. 8 shows a top view of the hawse hook in fig. 1.

The fluke body 11 has four receivers 14, said four receivers 14 being continuous in the longitudinal direction and arranged at the corners of the inner recess of the fluke 10, said fluke 10 otherwise being closed on the periphery. The upper receiving member 14 is separated from the lower receiving member 14 by two inclined surfaces 15 arranged spaced apart from each other. The ramp 15 starts centrally in the direction of the belt element 15 (here without an insertion) and rises slightly in the longitudinal direction, so that the receptacle 14 narrows in this longitudinal direction. The insertion slot 16 is provided between two mutually opposed inclined surfaces 14. The ramps 14 are terminated laterally by shoulders 27 so that each receptacle 14 is completely closed on three sides and closed to one third on one side. Centrally, a double spoiler receptacle 18 is present between the top and bottom sides of the main body 11. This is called a double receptacle, because two spoilers 12 are inserted into the space, one from the top and one from the bottom. In the centre between the receiving parts 14, there is therefore a receiving ramp 19, said receiving ramp 19 being evident on the side directed towards the elastic element 20 by the recess in the body 11. The shoulder or lateral guide rib 27 ensures that the clamping element 30 is fixed in its position relative to the middle. Two separate spoiler receivers 18 can also be provided if the upper and lower limiting walls of the insertion groove are designed continuously and do not end at the shoulder 27. In the case of a common spoiler receptacle 18 as shown in fig. 5 and 6, this can be further described as two spoiler receptacles 18, since the upper clamping element 30 of the element 20 is guided through the upper part and the lower clamping element 30 of the element 20 is guided through the lower part.

As is clear from fig. 7, in a side view, the body 11 can be designed to be curved, with the curvature oriented towards the trampoline centre. The side directed towards the outer clamping frame has a convex outer side 55 and the side directed towards the middle of the trampoline has a concave inner side 56, the spoilers 12 abutting directly on insertion.

Fig. 9 shows a perspective view of a spoiler 12, which can be used in fig. 1 and thus also in fig. 3. Fig. 10 shows a different perspective view of a spoiler 12, which can be used in fig. 2 and thus also in fig. 4. Fig. 11 shows a rear view of the spoiler 12 in fig. 9. Fig. 12 shows a front view of the spoiler 12 in fig. 9. Fig. 13 shows a side view of the spoiler 12 in fig. 9. Fig. 14 shows a top view of the spoiler 12 in fig. 9.

The spoiler 12 is inserted from the front from the side of the belt member 50. Fig. 9 shows the upper spoiler 12, the central body of which fills the upper receiving space in the spoiler receptacle 18, which is to be arranged above the belt element 50. The rear wall 63 abuts against the body 11 and prevents the clamping element 30 from sliding inwards. For this purpose, a hook 66 (also referred to as element 13 in fig. 1) is provided as a central tongue of the blocking element 64, which hook 66 can engage behind the body of the hawse hook 11. The latch member 64 is disposed rearward relative to the side wall of the spoiler body 62 through a transverse slot 65.

FIG. 15 shows a perspective view of the fluke 10 as shown in FIG. 2 with the strap member 50 inserted; the first elastic element 20 has been inserted into the lower receiving member 14, the opposite end of the elastic element 20 being ready to be inserted into the upper receiving position (inserted through the central zone and then laterally moved to the end position via the receiving position of the second end of the elastic element). Fig. 16 shows the view of fig. 15 from the outside as seen from the trampoline, and fig. 17 shows the view of fig. 15 from above.

Fig. 15 to 17 show a situation in which the flexible strip element has been pushed through the insertion slot 16 from the outside. Before the annular eye is pulled back, the retaining rod 51 has been inserted into the slot 16, so that the flexible band element 50 is locked. The insertion groove may in particular widen at the end remote from the rebound mat, so as to form a groove which narrows in the inward direction, in which the annular eye is held firmly by a force fit. In this case, advantageously, the complete loop eye is pulled into the fluke body 11, so that the force is already acting there and the loss of distance from the rebound pad to the elastic element 20 is as small as possible. This is attached, in particular sewn, to the free end of the rebound cloth or rebound mat. The clamping elements have been inserted into the respective receivers 14. Before this, the clamping element is moved laterally and positioned from the outside centrally through the receptacle 14 in the otherwise closed body 11 as a first clamping element 30; the second clamping element 30 in fig. 15 has just been pushed through the upper central receiving space 14 and is now moved laterally to the left (viewed toward the drawing page) behind the shoulder 27 in order to be locked in the upper left receptacle (viewed toward the drawing page), since the clamping element 30 tapers conically in the direction of the spring element 20 and thus corresponds to the shape of the ramp 15.

Figure 18 shows a perspective view of the fluke 10 of figure 1 with the strap member 50 inserted and without the elastic member 20 inserted. Fig. 19 shows a front view of the hawse hook 10 from outside the trampoline with four inserted clamping elements 30, which together with rubber cables 21 (not shown) form the elastic element 20, and with inserted strap elements 50 according to fig. 18. Fig. 20 shows a side view of the view in fig. 19. Fig. 21 then shows a top view of the views in fig. 19 and 20, while fig. 22 shows a sectional view along the line XXII-XXII in fig. 21. Fig. 23 shows a side view of the view in fig. 21. Fig. 24 shows a side view of the flexible strap member 50 with the retaining rod 51 inserted. Fig. 25 shows a top view of fig. 24 and fig. 26 shows a perspective view of fig. 24, showing how the flexible tape element 50 is inserted into fig. 2.

Fig. 18 shows only the flexible strip member 50 inserted in the insertion slot 16. Fig. 19 then shows the completely filled space of the receiving part 14, viewed from the front, viewed from the outside of the trampoline, filled with four clamping elements 30, which four clamping elements 30 belong to the two spring elements 20 and constitute elements but are not shown here. This element has a high stability due to the almost complete filling of the space enclosed by the body 11, which is further reinforced by the spoiler 12, which spoiler 12 projects towards the flexible band element 50 and is held on the opposite side in a form-fitting and force-fitting manner by the hook 66 on the blocking element 64 and in the body 11 of the hawse hook 10, as shown in fig. 20. This procedure allows a small mounting height of the fluke 11, since the clamping element 30 is inserted into the space that can be used multiple times and is locked in the fluke body 11 like the flexible strap element 50.

Figures 21 to 23 then show a cross-sectional view, a top view and a side view of the fluke 10 with the elastic element 20 and the flexible strap element 50. The belt members 50 have the same width in the longitudinal direction/transverse to the fixing direction. Here, the strap element 50 may also be narrower and gradually narrower towards the hawse hook 10, in order to still provide a wide securing strap at the mat or at the rebound cloth. Figure 23 clearly shows how the flexible strap member 50 tightly surrounds and covers the hawse hook 10.

Fig. 27 shows a perspective view of a clamping element 30 for a fluke, for example, the fluke 10 according to an exemplary embodiment of the invention. Fig. 28 shows a side view of the clamping element 30 from fig. 27, and fig. 29 shows a sectional view along the line XXIX-XXIX from fig. 28. The use of the resilient element 20 has already been described in fig. 1 to 26.

The clamping element 30 is C-shaped and has two free ends 31 with an insertion slot 32 between them. The free ends 31 are connected together via a hinge 33, in particular via an S-shaped film hinge. Following the insertion slot 32 is the region of the clip receiver 34 and the expansion space 35.

The side view of fig. 28 shows more clearly that the C-shaped clamping element 30 adjacent to the hinge 33 has two outer side walls 36 extending parallel to each other, which outer side walls 36 extend towards each other in a cone 37. The conical member 37 then forms a force fit with a complementary surface, such as the bevel 19 in the hawse hook 10, for tension applied to the rubber cable 21. The diameter of the inserted rubber cable 21 is advantageously only slightly smaller than the width of the front surface 38, so that the rubber cable 21 is greatly compressed in the insertion groove 32 in the region of the clip receiver 34. The rubber cable can expand again in the expansion space 35 behind the region of the clip receptacle 34 and substantially fill this expansion space. The hinge 33 also forms a stop for the advancement of the rubber cable 21. When the rubber cable 21 is inserted under tensile stress, the free ends of the clamping elements 30 amplify the force on the two inner holding surfaces formed by the bevels 15 or 115 or 117, wherein the free ends of the clamping elements 30 taper in a wedge-shaped manner on the outer side towards one another.

In a sectional view through the clip receiving member 34 in fig. 29, the central insertion slot 32 is surrounded by two webs 39 of the clip receiving member 34, adjacent to a laterally continuous clip space 41. These slots 41 extending through the clamping element 30 are provided to accommodate one or advantageously two clips 40, as shown in fig. 30 or 33.

Fig. 30 shows a perspective view of the clamping element 30 of fig. 27 with the rubber cable 21 and the clip 40 inserted. Fig. 31 shows a side view of the clamping element 30 of fig. 30, and fig. 32 shows a top view of the clamping element 30 of fig. 30, showing the hidden element. The clip 40 is a generally C-shaped spring steel member in which the free end 42 has a length (see fig. 32) such that the free end does not protrude from the clip space 41 on the opposite side. The mutual distance of the free ends 42, defined by the width of the connecting cover surface of the clip 40, is configured such that the clip 40 can be inserted under pressure into the groove 41 and grip or press the cone 37 inwards or outwards, wherein inwards gripping is preferred. The clip 40 has a width that fills the length of the clip accommodating member 34 with a gap (in the longitudinal direction of the rubber cable 21). A stop for clip positioning is set back from the side outer wall so that the clip and the retaining wall form a flat surface.

The diameter of the clip space 41 (i.e. the width of the slot or the thickness of the rubber cable 21 compressed in a direction parallel to the main plane of the hinge 33) may differ depending on the thickness of the cable. Then, substantially the space present in the clip receiver 34 varies and has the thickness of the web 39; the clip space 41 remains substantially the same, since the clip 40 may be the same in all cases. These differences occur when rubber cables 21 of different thickness grades are assembled due to different weights of users. Such rubber cables 21 have slightly different diameters.

Fig. 33 shows a perspective view of the clamping element 30 of fig. 27 with the inserted rubber cable 21 and two clips 140. Fig. 34 shows a side view of the clamping element 33 of fig. 30, and fig. 35 shows a top view of the clamping element 33 of fig. 30, showing the hidden element. In addition, fig. 36 shows a sectional view along line XXXVI-XXXVI in fig. 34, and fig. 37 shows a sectional view along line XXXVII-XXXVII in fig. 34. The difference between the clamping element 30 of fig. 30 and 33 is that in the embodiment according to fig. 30 the rubber cable is fixed by one wide clip 40, whereas in fig. 33 to 35 the rubber cable 21 is fixed by two clips 140 of approximately half the width, which are preferably introduced into the clip space 41 from opposite sides. Otherwise, the exemplary embodiment is identically configured. Fig. 36 shows a clip 140 of U-shape in which the length of the free end 142 is dimensioned so that it extends to the edge of the web 39. The clip 40 or 140 is advantageously inserted by closing the spring steel bracket.

Figure 38 shows a perspective view of another embodiment of a fluke 110 having two elastic elements 20 and a flexible strap element 50. Fig. 39 shows another perspective view of the embodiment in fig. 38, and fig. 40 shows a front view of the fluke 110 from the trampoline center according to fig. 38. Fig. 41 shows another perspective view of the hawse hook 110 according to fig. 38, wherein only one elastic element 20 has not yet been fully inserted.

The numbering of the reference numerals indicates that the same elastic element 20 and the same flexible strap element 50 may be used. The central insertion slot 16 is identically configured in size and the receiver 114 has the same shape (relative to the lower ramp 150) as in the hawse hook 10. The difference is that the body 111 is open towards the receiving piece 114 at four hook-shaped insertion slots 112 compared to the peripheral enclosing body 11, and for this purpose the body 111 has a central region 113 which constitutes an inner boundary for the cable insertion slots 112. For this purpose, the groove 16 for the flexible strip element 50 in the middle of the body 111 is also covered. Each individual clamping element 30 is individually passed through the side insertion slot 112 in situ, wherein when the clamping element is located in the region of the flexible band element 50, the rubber cable 21 is pressed through the cable insertion slot 112 and then pulled into the opening of the ramp 115, as shown in fig. 41.

Figure 42 shows a top view of the hawse hook 110 according to figure 38 with another flexible strap element 150. The strap member 150 is attached to the trampoline mattress by a wider tab, with the strap member 150 tapering towards the hawse hook 110.

Figure 43 shows a cross-sectional view of the hawse hook 110 of figure 38 with a clamping element 30 having two clamps 140 inserted. The inner slope 115 is located opposite the outer slope 117, the outer slope 117 corresponding to the outer ring of the trampoline and the thickening of the hawse hook 111 in the direction of the elastic element 20, in order to keep the cone of the clamping element firmly against tension.

In principle, it is possible to insert the spoiler 12 into the central blind holes 118, so that these blind holes act as spoiler receivers in the same way as the reference numeral 18. The spoiler to be inserted is then pressed into the opening 118 by force fit. The spoiler can also arrive as a flat blade above the central area 113 and be hooked on the opposite side of the hawse hook 111.

The blind hole 118 can also be a through hole, so that the spoiler 12 can be pushed through it in the same way as in fig. 1 and 2 and can be fixed by the latching hook 13 or 66 which has passed through the opening.

In the derivative of the hawse hook 110, the bevels 115 and 117 may also be arranged laterally or horizontally, as shown according to the exemplary embodiment of fig. 44.

Fig. 44 shows a perspective view of another embodiment of the hawse hook 210, wherein the flexible strap member 250 is used for only one elastic member 30, and fig. 45 shows a perspective view of another embodiment of the hawse hook 310 with the flexible strap member 250, also used for only one elastic member 30.

In fig. 44 and 45, the hawse hook 211 or 311 has only two receivers 214 or 114 for both ends of the cable element 21. The receiver in fig. 45 may be configured in the same manner as in the hawse hook 110. In the example of fig. 44, the receiver 214 is different in that the hawse hook has been inserted 90 ° rotated relative to the other embodiments, i.e. the cone extends laterally rather than from top to bottom. Thus, the side wall of the fluke body 211 is also a ramp 215. The flexible band element 250 is narrower and widens towards the rebound pad. In fig. 45, the fluke body 311 corresponds to "half" fluke body 111; the receiving members 114 are identically configured.
