the main umbrella rib except the side end umbrella rib is a middle umbrella rib which only exists in an angle of about 90 degrees between the two side end umbrella ribs;

the umbrella cloth only exists in an angle of about 90 degrees between the two umbrella ribs at the side ends.

Thus, only one support is needed to be erected between the ceiling and the ground, and the support can be easily arranged without effort. In addition, if the edge rib arranged at an angle of about 90 degrees is arranged along the building edge, the sunshade umbrella can be arranged at the building edge like an eave.

The sunshade umbrella of the invention is provided with more than two middle umbrella ribs, when the lower nest is in a state of being clamped on the convex part, four points of the two edge end umbrella ribs and the front ends of the two middle umbrella ribs are configured in a rectangular four-peak shape under a depression angle.

Thus, a rectangular umbrella cloth can be arranged on the sunshade like a sunshade.

The sunshade umbrella of the invention is provided with the telescopic part at the lower side of the support.

Thus, the upper side of the support is fixed on the ceiling and the length of the support is adjusted by the lower telescopic part, so that the support can be easily erected between the ceiling and the ground.

In the sunshade of the present invention, the middle ribs are sequentially arranged at equal angles from one side rib to the other side rib, and all the main ribs are equal in length.

Therefore, the sunshade umbrella can be shaped like a fan (including a semicircle) under the depression angle.

[ detailed description ] embodiments

Embodiments of the present invention will be described below with reference to the drawings.

[ example 1 ]

Fig. 1 is a front view, fig. 2 is a side view, fig. 3 is a rear view, and fig. 4 is a plan view of a sunshade 1 according to the present embodiment. As shown in fig. 1 and 2, a sunshade 1 is provided with a support 10 extending in the up-down direction. The pillar 10 is hollow cylindrical inside and is formed of, for example, iron or aluminum. An annular upper nest 11 is provided near the top of the support post 10 and fixed to the support post 10. An annular lower nest 12 is disposed below the upper nest 11 and can move up and down along the longitudinal direction of the support post 10 and penetrate through the support post 10. The upper nest 11 and the lower nest 12 are formed of, for example, synthetic resin.

Four main umbrella ribs 20 of equal length are joined at their ends to the upper nest 11. Each main rib 20 is rotatable in the vertical direction but not rotatable in the horizontal direction. Furthermore, the number of the main umbrella ribs 20 can be designed arbitrarily if it is three or more.

The lower nest 12 and the middle portion of each main umbrella rib 20 are connected by a support umbrella rib 30. When the runner 12 is moved along the support post 10, the main ribs 20 and the sub-ribs 30 are rotated in the vertical direction by the movement. The main rib 20 and the sub-ribs 30 are formed of, for example, stainless steel, aluminum, or iron by plating.

The support post 10 is provided with a protrusion 13 for limiting the downward movement of the lower nest 12. FIGS. 1 and 2 show a state in which the lower nest 12 is locked by the protrusion 13 located at the lower side so that its downward movement is restricted. The protrusion 13 is a locking component for limiting the downward movement of the lower nest 12. The top end of the protrusion 13 is protruded horizontally and has a slope inclined from the top edge of the protrusion toward the lower end toward the pillar 10.

A slit (not shown) extending in the up-down direction is formed on the outer peripheral surface of the pillar 10, and the protrusion 13 is protruded from the inside of the pillar 10 to the outside through the slit by a resilient structure (not shown) provided in the pillar 10.

As shown in fig. 1 and 2, when the lower nest 12 is locked to the protrusion 13, the protrusion 13 enters the pillar 10 when the protrusion 13 is forced toward the pillar 10 from the outside. Thus, the lower nest 12 can be released from the engagement with the protrusion 13, and the lower nest 12 can be moved below the protrusion 13. When sunshade 1 is stored and carried, lower nest 12 is moved to the lower side of projection 13 in order to reduce the volume, so that main rib 20 and sub-ribs 30 are arranged closer to support post 10.

When the lower nest 12 is located under the protrusion 13, if the lower nest 12 is moved upward and the lower nest 12 reaches the position of the protrusion 13, the protrusion 13 is pushed into the inner portion of the pillar 10 through the inner wall of the lower nest 12. Therefore, the lower nest 12 can move above the convex portion 13. When the lower nest 12 moves above the protruding portion 13, the protruding portion 13 protrudes from the inside of the support post 10 toward the outside, and the lower nest 12 is locked to the protruding portion 13, and each main rib 20 is arranged at a fixed position.

Here, the relationship between the lower nest 12 and the protrusion 13 is not limited to the drawings. FIG. 5 is an enlarged view illustrating the lower nest and the protrusion. The sunshade 1 is larger than a common sunshade, so the lower nest 12 is also larger. Therefore, as shown in fig. 5(a), the protrusion 13 is not positioned at the lower end of the lower nest 12, but the lower nest 12 is locked inside the lower nest 12.

In this case, a press button 14 for pressing the protrusion 13 into the pillar 10 is provided in the lower nest 12. As shown in fig. 5(B), pressing the press button 14 pushes the protrusion 13 into the pillar 10 to move the lower nest 12.

FIG. 6 is an enlarged view illustrating another structure of the lower nest. As shown in fig. 6(a), a disk portion 15 is provided in the lower nest 12. The disk portion 15 has a hole portion in the center through which the support 10 can pass.

As shown in fig. 6(B), the support column 10 is provided with a small diameter portion 10 x. FIG. 6(C) is a cross-sectional view taken along line S-S in FIG. 6(A) when the lower nest 12 is in the locked state. The disk portion 15 is pressed downward in the drawing through a spring 15 a. Therefore, the disk part 15 enters the small diameter part 10x and has a function of a locking component for limiting the downward movement of the lower nest 12.

As shown in fig. 6(D), the lower nest 12 can be moved downward by moving the disk portion 15 by pressing the press button 14 and inserting the support 10 through the hole portion, thereby releasing the engagement between the lower nest 12 and the disk portion 15.

FIG. 7 is an explanatory view of another structure of the movable lower nest. The wire 16 is connected to the lower nest 12, and the lower nest 12 moves upward when the wire 16 is pulled upward. If the wire 16 is not pulled upward to have a free length, the lower nest 12 will move downward due to its own weight.

The wire 16 is wound around the reel 17b around the pulley 17 a. The reel 17b can be rotated by operating a handle 17c provided on the outside of the column 10. The handle 17c is operated to wind the wire 16 around the reel 17b, thereby moving the lower nest 12 upward. In addition, if the metal wire 16 is removed from the wire winder 17b, the lower nest 12 may be moved downward.

When the lower nest 12 is moved upward and the lower nest 12 is locked in the unfolded state of the sunshade, the wire 16 has a function of a locking component for limiting the lower nest 12 to move downward.

In addition, in order to prevent the lower nest 12 from moving too much upward, a stopper (for stopping the protrusion of the lower nest) may be provided on the support 10.

In a plan view, the main umbrella rib 20 is composed of two side end umbrella ribs 201 arranged at an angle of about 180 degrees and two middle umbrella ribs 202 excluding the side end umbrella ribs 201. As shown in fig. 3, two side end umbrella ribs 201 form a straight line, and two middle umbrella ribs 202 exist only on one side of the straight line formed by the two side end umbrella ribs 201. The middle ribs 202 are arranged in order from one side rib 201 toward the other side rib 201 at an equal angle (here, 60 degrees). Furthermore, the number of the middle ribs 202 is not limited to two, and may be three or more, or may be only one.

An umbrella cloth 40 is provided between the main ribs 20. As shown in FIG. 3, the umbrella cloth 40 has one side of a straight line formed by two side ribs 201. In this embodiment, the edge ribs 201 and the middle rib 202 are integrally covered by one piece of umbrella cloth 40. In the covering, two side ribs 201 are positioned at a position corresponding to the diameter of the sheet 40, while the ends of the middle ribs 202 are aligned at a position corresponding to the circumference of the sheet 40. The umbrella cloth 40 can be made of various tent raw materials. The umbrella cloth 40 may be subjected to ultraviolet cutting treatment, inner surface waterproof coating, waterproof processing, and the like.

Here, since the cloth 40 is disposed obliquely, the main ribs 20 (the side end ribs 201 and the middle rib 202) are located on the opposite side of the cloth 40. In the drawings, the cloth 40 is transparent and the main ribs 20 (the side end ribs 201 and the middle rib 202) are non-transparent. And the lower edge of the umbrella cloth 40 is indicated by a single-point chain line. Of course, the umbrella cloth 40 may be non-transparent while the main ribs 20 (the side ribs 201 and the middle rib 202) are transparent.

Further, the umbrella cloth 40 is not limited to one piece, and three fan-shaped umbrella cloths having a central angle of 60 degrees may be used. In this case, the edge portions corresponding to the fan-shaped diameters of the umbrella cloths are connected along the longitudinal direction of the main ribs 20.

Further, an umbrella cloth 41 may be provided between both side end umbrella frames 201 (see fig. 2). As shown in fig. 3 (different from fig. 1 and 2, the umbrella cloth 41 is opaque), the umbrella cloth 41 covers the back side and is combined with the umbrella cloth 40 to wind around the sunshade 1.

The upper and lower sides of the support post 10 are respectively provided with telescopic parts 101 and 102. When the support post 10 is installed as a support rod under the eave of a building, etc., the length of the support post 10 can be adjusted to be equal to the distance from the ceiling to the floor surface through the telescopic parts 101 and 102.

The telescopic structure of the telescopic parts 101 and 102 can be a well-known one. For example, the structure shown in FIG. 8 can be used. Although the lower stretchable part 102 is shown in the drawings, the upper stretchable part 101 may have the same structure. By locking the inner thread 102b of the telescopic part 102 with the outer thread 10y of the pillar 10, the length of the telescopic part 102 protruding from the pillar 10 (the height of the sunshade 1) can be adjusted by rotating the telescopic part 102.

Semicircular pads 101a, 102a are provided at the top ends of the expansion parts 101, 102. The pad 102a is rotatable relative to the expansion part (body) 102 without screws. With this structure, when the pad 102a is contacted with the ground and kept fixed, the extension part 102 can be rotated to adjust the height of the sunshade 1. Further, if the bottom surface is flat, the pad 102a does not need to be semicircular, and may have a disk shape or other shapes.

The upper telescopic part 101 is disposed above the umbrella cloth 40 and the upper nest 11. Therefore, when the sunshade 1 is installed at the front end of the eave, the length of the support post 10 located above the canopy 40 (i.e., between the canopy 40 and the ceiling at the front end of the eave) is adjusted to a desired length by the upper expansion part 101, and then the length of the support post 10 is adjusted to a distance as long as the distance from the ceiling at the front end of the eave to the ground.

Here, the expansion portions 101 and 102 are not both required to be provided, and for example, only the lower expansion portion 102 may be provided, and only the pad 101a may be provided on the upper side. Since the length of the upper side of the umbrella cloth 40 is substantially constant, the length of the support pole 10 can be adjusted only by the lower telescopic part 102.

Here, when only the pad body 101a is provided on the upper side, the pad body 101a and the pad body 102a may be designed as the same component in consideration of the ease of production. Thus, both the pad 101a and the pad 102a can rotate. Considering that there is a danger of rotation of the support post 10 (and the sunshade 1), it is preferable to fix the pad 101a to the support post 10 by locking or the like to restrain the rotation of the support post 10.

The steps when the sunshade 1 is installed under the eave of a building will be described. A sunshade 1 is provided with a lower nest 12 located below a projection 13, and main ribs 20 and sub-ribs 30 arranged adjacent to a support post 10.

First, according to the purpose of use or preference, the distance between the ceiling and the canopy 40 is determined by approaching the canopy 40 to the ceiling under the eave, or by keeping a certain distance between the canopy 40 and the ceiling. The length of the upper expansion part 101 of the support 10 is adjusted according to the determined distance between the ceiling and the umbrella cloth 40. However, if the distance between the ceiling and the umbrella cloth 40 is fixed, the upper expansion part 101 may be omitted.

Then, the length of the expansion part 102 under the support post 10 is adjusted according to the distance between the ceiling and the ground under the eave, and the support post 10 is erected between the ceiling and the ground in a support rod state.

Then, the lower nest 12 is slid upward along the support post 10 to the upper side of the protruding portion 13, and the main ribs 20 are horizontally arranged and the umbrella cloth 40 is spread, and the lower nest 12 is locked to the protruding portion 13. This completes the sunshade 1 setting.

Thus, when the sunshade 1 is installed at the front end of the eave of a building, the length of the post 10 can be adjusted by the telescopic parts 101 and 102 (or only the telescopic part 102), and after the post 10 is erected between the ceiling and the ground, the lower nest 12 is only required to be moved upward and locked on the protrusion 13, so that the sunshade can be easily installed without difficulty.

[ example 2 ]

Next, example 2 is explained. The description already in example 1 will be continued. The main description differs from embodiment 1, and the detailed description of the common parts will be omitted. Fig. 9 is a top view of the sunshade 1a according to the present embodiment.

The main rib 20a of the sunshade 1a according to the present embodiment is composed of two side end ribs 201 and two middle ribs 202 a. When the lower nest 12 is placed above and the sunshade is unfolded, as shown in fig. 9, two side end ribs 201 and two middle ribs 202a are arranged at four vertices of a rectangle in a downward view. The whole body of the side end umbrella ribs 201 and the middle umbrella ribs 202a is covered by a rectangular umbrella cloth 40a with four front ends of two side end umbrella ribs 201 and two middle umbrella ribs 202a as vertexes.

Thus, the four front ends of the two side ribs 201 and the two middle ribs 202a are arranged to form four vertices of a rectangle in a downward view, so that the shape of the umbrella cloth 40a can be a wide rectangle regardless of the number of the pillars 10 of the sunshade 1 a.

Since the cloth 40a is disposed obliquely, the main ribs 20a (the side end ribs 201 and the middle rib 202) are located on the opposite side of the cloth 40 a. In the drawing, the umbrella cloth 40a is transparent and the main ribs 20a (the side end ribs 201 and the middle rib 202) are non-transparent. The lower edge of the umbrella cloth 40a is indicated by a single-point locking line. Of course, the umbrella cloth 40a may be non-transparent and the main ribs 20a (the side end ribs 201 and the middle rib 202) may be transparent.

Further, in order to prevent the umbrella cloth 40a from being loosened, for example, as shown in fig. 10, if the sunshade umbrella 1 is horizontally long, when the lower nest 12 is engaged with the protruding portion 13, a middle rib 202b may be provided in the horizontal direction and extending in the vertical direction with respect to the side end rib 201. In this case, one more support rib 30 is additionally provided to connect the middle rib 202b and the lower nest 12.

[ example 3 ]

Next, example 3 is explained. The description already in examples 1 and 2 will be continued. The differences from embodiments 1 and 2 will be mainly described, and the detailed description of the common parts will be omitted. FIG. 11 is a plan view of the sunshade 1b according to this embodiment.

The main rib 20b of the sunshade 1b of the present embodiment is composed of two side end ribs 201b and two middle ribs 202 b. Two side end umbrella ribs 201b are arranged at an angle of 90 degrees. When the lower nest 12 is placed above and the sunshade is unfolded, as shown in fig. 11, the sunshade is in a quarter-circle shape in a top view.

Thus, the sunshade 1b can be installed at a corner of a building because it is a quarter-circle in a top view.

[ example 4 ]

Next, example 4 is explained. An assembly for adjusting the length of the support is provided, which is suitable for use in any of the parasols described in embodiments 1, 2, and 3. The structure of the support column 10 is the same as that of embodiments 1, 2 and 3 except for the other portions. The support post 10 will be mainly described, and detailed description of the other parts will be omitted.

FIG. 12 is a schematic view of a pillar structure. The telescopic strut 10 itself is largely (e.g., 30cm) adjustable in length (but may not be adjustable). As shown in FIG. 12(A), the pillar 10 is composed of an outer tube 10a and an inner tube 10b, and the outer tube 10a is provided with a hole portion 18a, and the inner tube 10b is provided with a hole portion 18b, respectively.

The length of the inner tube 10B extending from the outer tube 10a is adjusted by inserting the inner tube 10B into the outer tube 10a (see fig. 12B).

One of the plurality of hole portions 18b is fixed to the hole portion 18 a. The length of the hole 18a is adjusted by connecting any one of the holes 18 b. Furthermore, a plurality of holes 18a may be provided, and only one hole 18b may be provided.

The hole part 18b connected to the hole part 18a is fixed, as shown in FIG. 12C (schematic cross-sectional view of the hole part), by inserting a cross bar 19 into the hole part 18a and the hole part 18b to fix the length (up-down position of the hole part 18 b). For example, the cross bar 19 may be a bolt and secured by a nut 19 a.

In this case, the protrusion 13 or the grip 17c is provided on the outer tube 10 a. When the umbrella is used as a sunshade, the position of the lower nest 12 (the position of the protrusion 13) is fixed, and it is difficult to install the protrusion 13 or the handle 17c on the movable inner tube 10 b.

Here, on the upper side of the support 10, the lower nest 12 moves around the periphery. In the case of the telescopic strut 10 itself, since the inner tube 10b is inserted into the outer tube 10a, it is preferable to use the upper side of the strut 10 as the outer tube 10 a.

FIG. 13 is a schematic view of a pillar structure. The structure is different from that of FIG. 12. As shown in FIG. 13(A), a part of the inner tube 10c is provided. The inner tube 10b of FIG. 12(A) is composed of two partial inner tubes 10b, 10 c.

The lower end of the partial inner tube 10c is reduced in diameter so as to be inserted into the partial inner tube 10 b. In addition, the upper sides of the partial inner tube 10b and the partial inner tube 10c have the same diameter and have holes 18b, 18 c. That is, only a part of the inner tube 10b may be used as the inner tube (the same as fig. 12), or a part of the inner tube 10c may be inserted into the part of the inner tube 10b to couple the part of the inner tube 10b and the part of the inner tube 10 c. The state in which a part of the inner tube 10B and a part of the inner tube 10c are used as inner tubes is shown in FIG. 13 (B).

The meaning of a part of the inner tube 10c is explained. In use as shown in FIG. 12, the depth to which the inner pipe 10b can be inserted into the outer pipe 10a (i.e., the length of the stay 10 is adjustable) is controlled by a reel 17b or the like. Here, when the partial inner tube 10b and the partial inner tube 10c are combined to be used as inner tubes, if deep insertion is desired, the partial inner tube 10c is removed and only the partial inner tube 10b is used as an inner tube, and thus, the depth is equivalent to the length of the reinsertible portion inner tube 10 c. That is, the length of the strut 10 may be increased by an adjustable amount.

As shown in FIG. 13(C), a part of the inner tube 10C is inserted into the outer tube 10 a. Here, in the state shown in fig. 13(C) where only a small portion of the tip end of the partial inner tube 10b is inserted, the partial inner tube 10C is removed and only the partial inner tube 10b is used as an inner tube. Since the insertion depth of a part of the inner tube 10b is small, the fixation with the outer tube 10a is insufficient. It is preferable to remove a part of the inner tube 10c when the part of the inner tube 10b is inserted to a sufficient depth.

Thus, it takes a lot of labor to connect the part of the inner pipe 10b and the part of the inner pipe 10 c. The connection can be made by using a cross bar 19 as shown in FIG. 12C, but the cross bar 19 (including a nut 19a) of the connection portion is projected to the outside of a part of the inner tube 10 b. A part of the inner tube 10b cannot be inserted into the outer tube 10a due to the protrusion. The connection should be made in such a way that the elements do not protrude to the outside, for example, in such a way that the expansion spring elements extending from a part of the inner tube 10c are snapped into a part of the inner tube 10 b. Further, if a part of the inner tube 10c is inserted into the inner tube 10b and the connection part is located below, the connection may be performed by the cross bar 19.

Further, the number of the partial inner tubes 10c is not limited to one, and two or more may be used. The adjustable amount of the length of the strut 10 may be greater.

FIG. 14 is a schematic view of the arrangement of the holes. Only one hole 18a in fig. 12 and 13 is provided. Here, the spacing D2 of hole portion 18b is three times the spacing D1 of hole portion 18 a.

The length of the support post 10 is set by selecting the hole 18a and the hole 18b into which the cross bar 19 is inserted and by the D1 scale. If the insertion length when the lowermost hole 18a is joined to the hole 18b is L, the insertion lengths when the other holes 18a are joined to the hole 18b are L + D1 and L +2D 1. The insertion length of L +3D1 can be achieved by selecting other hole portions 18 b. That is, the length of the mast 10 can be set with the D1 scale. For example, if D1 is 2cm and D2 is 6cm, the length of the strut 10 can be set on a 2cm scale.

In general, the number of the hole portions 18a is not limited to three, and if the number is n, the same applies to D2 — nD 1.

D1 is discussed herein. First, the telescopic strut 10 itself is coupled to an approximate length by D1 scale, and the length is finely adjusted by the telescopic part 102. That is, if D1 is smaller than the length of the telescopic part 102, the length of the strut 10 can be arbitrarily set.
