Technical Field
The invention relates to a harness comprising a support base, a support strap unit for supporting the base, and a retaining device for releasably retaining a battery pack in a supported position on the support base, wherein the retaining device comprises: a docking mechanism on the support base for pivotally docking the battery pack in a docked position; and a securing mechanism on the support base for securing the battery pack in a support position pivoted towards the support base relative to the rest position, and to a kit with such a harness.
Background
The support base is used for receiving an object to be carried, for example by fixing the object on the support base or by introducing the object into a receiving space of the support base. The support belt unit serves to allow the user to wear the support base on his back, while the object is located on or in the latter.
The harness can in particular be designed to carry a battery pack, in particular a battery pack as follows: the battery pack can be worn on the back and supplies electrical energy to a hand-held power tool, in particular an electrically powered gardening and/or forestry tool. In the present case, hand-held power tools are to be understood as, in particular, power tools which are carried by hand or guided along the ground, in particular those used for gardening and/or forestry work, such as power saws, hedge trimmers, leaf blowers, sweepers, lawn mowers, scarifiers and the like, to name a few. The battery pack is designed to be worn on the back of a user by means of a harness system and to supply the electrical energy required by the power tool during use, for which purpose it has a suitable accumulator unit, which here is to be understood as any desired conventional accumulator or battery unit. Typically, the battery cells are arranged to form accumulator cell blocks.
When used to carry a battery pack, the harness has a retaining device for releasably retaining the battery pack in a supporting position on the support base. Various securing or retaining mechanisms for such retaining devices are known. In one of these known types, the battery pack is placed in a translational approach movement onto a support base, which may be formed, for example, by a plate-like support structure, and subsequently brought into a supporting position, for example from the top downwards, in a displacement movement perpendicular to the approach movement. In this context, see, for example, publications US 2016/0345714 a1 and WO 2018/007111 a1, and also utility model publications DE 202012013284U 1 and DE 202013011447U 1. Unless otherwise stated, reference herein in terms of positional orientation is made to the orientation of the harness when it is located on the back of a user, or to the orientation of the battery pack in its support position in the harness located on the back of a user. In an alternative type considered here, the holding device has: a docking mechanism (docking mechanism) on the support base for pivotally docking (dock) the battery pack in a docked position; and a securing mechanism on the support base for securing the battery pack in a support position that is pivoted toward the support base relative to the rest position.
Publication EP 2819207 a1 discloses such a retaining device according to the preamble of claim 1, wherein the parking mechanism is formed there by an upper edge of the support base, on which upper edge the hook-shaped configuration of the upper edge of the battery pack can be engaged in such a way that: so that a certain pivotability of the battery pack with respect to the support base is maintained, with the upper edge of the support base acting as the pivot axis. The function of the securing mechanism is provided by two locking protrusions which are arranged laterally on the support base in a lower region of the support base and interact with corresponding mating locking protrusions in a lower lateral region of the battery pack so as to form a releasable snap connection, wherein the handle is arranged on the underside of the battery pack, i.e. on the underside thereof in a support position on the back of the user.
In most cases, the support band unit of the harness includes a shoulder strap unit as a support aid for the user. For the respective use, it is also advantageous if the support belt unit has a belt unit. In such a typical harness, the support belt unit additionally has a coupling unit that connects the belt unit to the support base in an articulated manner. In the aforementioned utility model publication DE 202013011447U 1, the coupling unit comprises a joint by which a cross piece is pivotably coupled to the support base about a substantially horizontal pivot axis perpendicular to the plane of the plate-shaped support base, wherein the cross piece is used for fixing a waist belt. In the harness disclosed in publication DE 102015002724 a1, the coupling unit comprises a joint, which is preferably formed by a fabric/film hinge, and by means of which the waist belt unit is pivotably connected to the support base about a substantially horizontal pivot axis parallel to the plane of the plate-shaped support base. This is intended to facilitate the inward folding of the belt unit when the harness is laid down and in this way prevent the belt unit from forming an obstacle to the harness being laid down in an upright position.
Also known are harnesses of the type mentioned at the outset in which the support strap unit has at least one shoulder strap unit which can be releasably connected to the support base and which can be adjusted to modify the height of the support base. Conventionally, in most cases, this is achieved by the fact that: a strap fabric (strap web) adjustable in length is used for the respective shoulder straps of the shoulder strap unit.
Disclosure of Invention
The object of the invention is to provide a harness of the type mentioned at the outset which is improved over the harnesses of the prior art described above, in particular with regard to the way in which the battery pack is fixed to the support base, and to provide a kit of tools equipped with such a harness.
The invention solves this problem by providing a harness having the features of claim 1 and a kit of tools having the features of
According to the invention, the harness is designed to allow a user to carry a battery pack on his back for supplying electrical energy to a hand-held power tool, which may in particular be a powered gardening and/or forestry tool. For this purpose, the harness comprises a support base, a support strap unit for the support base, and a retaining device for releasably retaining the battery pack in a supported position on the support base, wherein the retaining device comprises: a docking mechanism on the support base for pivotally docking the battery pack in a docked position; and a securing mechanism on the support base for securing the battery pack in a support position pivoted toward the support base relative to the rest position. The parking mechanism is characteristically arranged on a lower region of the support base.
By means of these features of the harness, a battery pack can be coupled to the harness in a very advantageous manner. For this purpose, it uses said parking mechanism to park onto the lower region of the support base and can then be pivoted towards the support base in order to reach the support position. If the top of the battery pack is provided with a handle, it can be held by the handle when it is parked onto the lower region of the support base and then pivoted towards the support base up to the support position.
When placing the battery pack onto the harness and removing the battery pack from the harness, the handling of the battery pack can in this way be limited to the upper region of the battery pack and harness; the user does not necessarily need to manipulate the lower regions of the battery pack and harness. When a user wishes to place the battery pack on the harness while the harness is on the ground or a resting surface, this generally makes handling easier for the user. Furthermore, the side of the support base on which the battery pack is to be placed remains clearly visible to the user after the battery pack has been parked, which makes it easier for the user to pivot it into the support position. The parking of the battery pack at the lower region of the support base is also advantageous for stability reasons, since the tilting moment associated with the parking of the battery pack can be kept low for the harness, in particular much lower than if the battery pack was parked on the central or even upper region of the support base.
According to one aspect of the invention, the securing mechanism has a securing slide which is displaceably arranged on the support base between a release position and a securing position and has a securing hook which is designed to engage securely behind a corresponding mating securing element of the battery pack in the support position. This constitutes a structurally simple and functionally advantageous embodiment of the fastening means. In the case of a battery pack that is not parked, the fixing slide is in the fixing position, wherein it has a continuous ramp, which by interaction with a matching fixing element of the battery pack is designed to automatically displace the fixing slide in the direction of the release position when the battery pack parked on the support base is pivoted inwards in the direction of the support position. By this measure, the stationary slide can be automatically moved out of the stationary position by pivoting the battery pack inwards into its supporting position, without separate actuation by the user for this purpose. In this case, the fixing slide can preferably be pretensioned in the direction of the fixing position by means of a corresponding elastic pretensioning element. During the inward pivoting of the battery pack into its supporting position, the fixing slide is then displaced into the release position counter to the action of the pretensioning element, and the pretensioning element can automatically return the fixing slide to its fixing position as soon as the battery pack reaches its supporting position.
According to an alternative aspect of the invention, the fixing mechanism has a fixing lever which is pivotably arranged on the support base between a release position and a fixing position and has a fixing bow which is designed to engage firmly behind a corresponding mating fixing element of the battery pack in the support position. This also constitutes a structurally simple and functionally reliable construction of the fixing means and constitutes a construction which is advantageous from the point of view of handling.
In a development of the invention, the parking mechanism provides a pivot axis which is substantially parallel to the underside of the support base and which is used for the pivotal movement of the battery pack into the support position. This also helps to optimize handling of the battery pack when it is placed on or removed from the harness.
In a development of the invention, the fixing bow has a continuous surface extending in an arc, which has a non-constant spacing from the pivot axis of the fixing rod, against which the mating fixing element can be placed with a spacing from the pivot axis, which decreases as the pivoting of the fixing rod in the direction of the fixing position increases. This makes it easier to safely pivot the battery pack to its supporting position on the support base. In particular, these particular kinematics of the fixing bar allow an optimal force distribution of the inward pivoting force or fixing force exerted on the battery pack. In a corresponding embodiment, the continuous face preferably extends along its entire length, at least in an admissible region with a reduced spacing from said pivot axis, until its end point corresponding to the fixed position of the fixed lever, or alternatively only to a point spaced from the end point, and from that point its spacing from said pivot axis is no longer reduced until the end point is reached, or at least no longer reduced over a part of the remaining length of the continuous face.
In a development of the invention, the fixing bow has a continuous surface extending in an arc, which has a non-constant spacing from the pivot axis of the fixing rod, against which the mating fixing element can be placed with a spacing from this pivot axis, wherein the continuous surface extends from a starting point up to an end point corresponding to the fixing position of the fixing rod, and the spacing of the continuous contact points of the continuous surface with the mating fixing element decreases with increasing pivoting of the fixing rod from the starting point in the direction of the fixing position until an inflection point of the continuous surface is reached, and the continuous surface is designed at the inflection point to provide a reversal of the torque that can be exerted on the fixing rod by the mating fixing element, namely: from a torque acting in the direction of the release position to a torque acting in the direction of the fixing position. These particular kinematics of the fixing lever allow an optimum force distribution of the inward pivoting force or fixing force exerted on the battery pack, and the particular torque reversal on the fixing lever at the inflection point ensures that the fixing lever, under the action of a force in the direction of the rest position, subjects the battery pack to a torque in the direction of its fixing position when the fixing lever is seated at the inflection point on its side facing the end of the continuous face. The latter has the following effects: the action of such a force on the battery pack does not cause the battery pack to pivot further outwardly, but rather the securing lever secures the battery pack in a position corresponding to the position of the mating securing element at the inflection point of the continuous face.
In a development of the invention, the fixing lever has an ejector profile which, during pivoting of the fixing lever in the direction of the release position, is designed to exert an ejection force on the battery pack which acts in the direction of the rest position. This measure has the following advantages: the pivoting of the battery pack from its supporting position outwards to its resting position can be assisted by pivoting of the fixing lever in the direction of the release position, i.e. a pivoting assist is provided in such a way as to assist the pivoting of the battery pack from its supporting position outwards to its resting position.
In one embodiment of the invention, the ejector contour has an ejection pressure face which acts on a mating contact face of the battery pack on the side of the fixing bow facing away from the continuous face and/or an ejection pressure face which acts on a mating fixing element of the battery pack on the side of the ejector cam of the fixing lever facing the continuous face. Both measures constitute, individually or in combination, an advantageous embodiment for allowing the fixing bars to exert a discharge force on the battery pack. In a combined embodiment, the two discharge pressure faces may complement each other according to the system configuration, so that they function in different pivoting ranges of the fixing rod, or at least simultaneously in a partial range of the entire pivoting movement of the fixing rod.
In a development of the invention, the fixing slide or fixing lever has a user-actuated control element on the side of the support base facing away from the battery pack coupling side of the support base. This facilitates handling by the user when bringing the battery pack from its rest position to its support position. For this purpose, the user can control the fixing slider or fixing rod from the side of the support base facing away from the side of the support base for coupling to the battery pack. Thus, such control actuation is not impeded by the parked battery pack.
In a development of the invention, the holding device has a damping spring arrangement which, in the supporting position of the battery pack, provides an elastic damping for the battery pack, the elastic damping having an elastic force acting in the outward pivoting direction. This helps to securely hold the battery pack in its supporting position on the support base without a gap. Since the elastic force of the buffer spring arrangement acts on the battery pack in the outward pivoting direction away from the support base, the buffer spring arrangement can avoid an unexpected sudden impact of the battery pack on the rigid portion of the support base. Due to the elastic force of the buffer spring arrangement, the outward pivoting barrier advantageously serves to block outward pivoting of the battery pack. This outwardly pivoted barrier can be released when the user wishes to detach the battery pack from the support base and for this purpose initially pivot it from its support position to its rest position. The fixed slide or rod preferably acts as such an outwardly pivoted barrier, or alternatively a separate outwardly pivoted barrier may be provided.
In one development of the invention, the harness comprises a support base and a support belt unit for the support base, wherein the support belt unit has a shoulder belt unit, a waist belt unit and a coupling unit which connects the waist belt unit to the support base in an articulated manner. The coupling unit comprises a double joint by which the waist belt unit is connected to the support base so as to be pivotable about two pivot axes, wherein one of the two pivot axes extends substantially parallel to the plate plane of the support base and the other pivot axis extends substantially perpendicularly with respect to the plate plane of the support base.
This constitutes a very advantageous embodiment for hinging the belt unit on the support base so as to be pivotable about two axes, without requiring two separate coupling units and without two such joints capable of interfering with each other. By means of this double joint, the belt unit can be pivoted to the desired extent in each case relative to the support base about a pivot axis which is substantially parallel to the plate plane of the support base and also about a pivot axis which is substantially perpendicular relative to the plate plane of the support base. Both pivotal mobilities are advantageous in providing a corresponding yaw movement of the belt unit relative to the support base.
In one embodiment of the invention, the coupling unit, and therefore the double joint, is formed by an autonomous (autonomous) component which is fastened on the one hand to the belt unit and on the other hand to the support base. Such a coupling unit can be manufactured with high load-bearing capacity and long service life and does not limit the material choice of the belt unit and the support base.
In one embodiment of the invention, one pivot axis extends substantially between and parallel to the two mutually facing side edges of the belt unit on the one hand and the support base on the other hand, and the other pivot axis extends offset with respect to the pivot axis in a direction away from the belt unit. This results in advantageous kinematics of the pivotability of the belt unit relative to the support base.
In one development of the invention, the harness comprises a support base and a support belt unit for the support base, wherein the support belt unit has at least one shoulder belt unit which can be releasably connected to the support base. Characteristically, the shoulder strap unit in this modification includes: at least one flexurally stiff strap holder which can be releasably locked at several different heights on the support base by means of a lock mechanism; and at least one flexible webbing connected to the strap retainer. The flexurally rigid design of the strap holder allows the shoulder strap unit to be restrained to the support base in a very stable position. The possibility of being able to releasably lock the strap holder at several different heights on the support base provides advantageous height adjustability of the shoulder strap unit. In contrast to a strap holder, designing the strap fabric to be flexible rather than stiff in bending allows the user to comfortably wear the harness in a conventional manner.
In one embodiment of the invention, the lock mechanism provides several locks for the at least one strap holder at different heights on the support base, wherein the respective locks comprise a lock release position and an upwardly biased lock holding position relative to the lock release position, between which positions the strap holder is vertically displaceable on the support base. In this lock release position, the strap retainer may be attached to or removed from the support base at a desired height. In this lock retaining position, the strap retainer is connected to the support base in a locked manner such that it cannot be released from the support base. To release the strap retainer from the support base, the strap retainer must be moved downward to a latch release position. The upwardly biased arrangement of the lock retaining position relative to the lock releasing position has the advantage that: the weight acting on the support base in the downward direction cannot cause the tape holder to inadvertently move to the lock release position. In contrast, such a weight of the support base has the following effects: the strap retainer is securely retained in the lock retaining position.
In one embodiment of the invention, the lock mechanism has a releasable snap-in lock that keeps the tape holder locked in the respective lock holding position. Only after this snap-in lock is released by the user can the tape holder on the support base be moved down to the lock-releasing position and subsequently detached from the support base or placed again thereon at a different height. This constitutes an additional safeguard for a height-adjustable mounting of the support holder on the support base.
In a further aspect, the invention provides a tool kit comprising a harness according to the invention and a battery pack which can be worn on the back, can be fixed to the harness and supplies electrical energy to a hand-held power tool, in particular a powered gardening and/or forestry tool. The battery may in particular be of the kind disclosed in the european patent application of the present applicant with application number 18194901.7, the content of which is hereby fully incorporated by reference into the disclosure of the present application.
In one embodiment of the invention, the kit additionally includes a hand-held power tool that can be powered by the battery pack.
