Description

[0001] The invention relates to a holder which serves to accommodate and securely hold a transport chair.

[0002] Such holders are known in practice from the field of emergency vehicles. In the context of the present invention, a transport chair is defined as a mobile chair which is used to transport persons with limited mobility, in particular with limited walking ability. Unlike wheelchairs, the transport chair is not used as a permanent aid to the patient's mobility, but rather to transport the patient between their current location and an ambulance or from the ambulance to the next location. The transport chairs are designed to be foldable so that they can be transported flat together in the ambulance. For this purpose, they are hung on a holder which can be arranged either inside the ambulance, for example on a rear door, or in a storage compartment of the ambulance which is accessible from the outside.

[0003] While elevators make it easier to climb multiple floors in medical facilities such as hospitals or nursing homes, such built-in aids are often not available when patients are picked up from their homes. It is therefore common practice to equip transport chairs with a stair-climbing aid in the form of a motor-driven element that makes it easier to control the transport chair both up and down stairs. Due to the typically electric motor drive and the associated energy storage device, such transport chairs are significantly heavier than non-motorized transport chairs. In addition, the transport chair may also have other electrical devices installed, such as lighting.

[0004] The invention is based on the object of improving a holder for a transport chair in such a way that it enables easier handling of the transport chair when it is placed in the holder and removed from the holder.

[0005] This object is achieved by a holder according to claim 1 and an arrangement according to claim 11. Advantageous embodiments are described in the subclaims.

[0006] In other words, the invention proposes that the holder be designed essentially in two parts, namely with a first assembly that is fixed as a base to a wall, for example a body part of an emergency vehicle, or possibly a movable body part such as a vehicle door. A so-called horizontal fitting can also represent a movable vehicle wall, namely a fitting that allows the holder to be moved between a first rest position, which extends comparatively deeper into the vehicle, and a second use position, which extends comparatively less deeply into the vehicle. The movement itself, which the horizontal fitting or the holder attached to it performs, can, but does not necessarily have to, be exactly horizontal.

[0007] The second assembly serves as a holder for the transport chair. This holder is height-adjustable relative to the base between a lower and an upper position. In the lower position, the transport chair can be inserted into the holder at approximately the same height. For example, depending on the design of the holder, it can be rolled into the holder on its wheels, or alternatively, it can be raised to a low, easily manageable height and inserted or hooked into the holder when the holder is in its lower position. The holder can, for example, be lowered to the ground level on which the rescue vehicle is standing with its wheels, and then assumes its lower position. The holder is then raised from the lower to the upper position so that the vehicle door mentioned above as an example can now be closed.The lifting process, in which the support is now loaded with the additional weight of the transport chair, is carried out in accordance with the invention with power assistance.

[0008] In comparison to the staff having to lift the transport chair into a raised position in order to connect it to a one-piece, fixed height holder at the appropriate height, the power assistance enables the staff to work in a much more ergonomic and back-friendly manner. The power assistance can be implemented in a variety of ways: in one design, purely mechanical support can be provided, for example by means of a gear, a pulley or the like, so that the holder together with the transport chair can be cranked or pulled upwards, for example. A considerably time-saving method of working can be made possible by using an electric drive as power assistance, so that the holder together with the transport chair can be raised by an electric motor and later lowered again.

[0009] In one design considered advantageous, the force support is implemented using a spring. The spring acts as a force accumulator, which is tensioned when the support, loaded with the transport chair, is lowered. This ensures that the support and transport chair do not fall downwards unhindered, due to gravity alone. Rather, the spring acts as a brake. When the transport chair is later held against the support and then needs to be lifted together with the support, this upward movement is assisted by the spring, allowing the personnel to perform this movement with minimal physical effort.

[0010] In one design, a gas tension spring is used as the spring. This enables a particularly compact, space-saving design. Furthermore, unlike coil springs or similarly open springs, the spring's design in the form of a telescopic cylinder prevents external obstacles from entering the spring and either damaging it and / or impairing its function.

[0011] In one embodiment, springs are arranged on both sides next to the base. This supports the flattest possible design of the mount compared to a single central spring, since the two lateral springs have a smaller diameter than a central spring. To enable a long adjustment range, two or more springs can be arranged on each side in a tandem arrangement in their axial direction. To achieve a high spring force, two or more springs can be arranged next to each other in a parallel arrangement on each side.It is advantageous for the holder to be as flat as possible so that the folded transport chair, when attached to the holder, interferes with the freedom of movement of the personnel in the interior of the ambulance as little as possible. If the transport chair is stored in a storage compartment accessible from the outside, the depth of this storage compartment is predetermined and limited by the design and is usually small in order to ensure the largest possible interior space.

[0012] Instead of placing a spring on each side of the base, tilting of the mount relative to the base can be prevented by guiding the mount along the base for a sufficiently long distance, e.g. using a telescopic fitting with a ball bearing guide. The long guide makes it possible to place a spring - or even several springs - on just one side of the base. This leaves space on the opposite side to mount a damping element, e.g. in the form of a telescopic damper. If this can be approximately the same dimensions as the spring on the first side of the base, it can be mounted in the same attachment points as the spring instead of a spring.

[0013] Regardless of whether springs are arranged on only one or both sides of the base, the mount in one embodiment includes one or more damping elements to limit the speed of movement of the mount relative to the base. For example, one or more rotational damping elements can be used, which have comparatively small dimensions. The damping elements used can be double-acting, so that they exert their damping effect in both directions of movement.

[0014] However, the lowering movement of the support is often limited anyway, for example by the spring mentioned above, which is tensioned when the support is lowered. By adjusting the spring strength to the weight of the support and the transport chair on it, the desired limitation of the lowering speed is achieved. Therefore, single-acting damping elements can be used that only exert their damping effect in one of the two directions of movement, namely the upward movement of the support. Should the support occasionally - and possibly accidentally - be moved upwards without the transport chair, the damping prevents the risk of accidents, as the upward movement does not occur unexpectedly and suddenly, but rather at a limited speed.When the holder is moved upwards together with the transport chair, the effect of the spring is not hindered by the damping element, but merely reduces the speed of the movement.

[0015] The height adjustment of the support relative to the base can be achieved using various fittings, such as a parallelogram fitting, a scissor fitting, or the like. Compared to moving the support in an arc-shaped motion relative to the base, a linear guide is advantageous because, for example, it does not require the personnel handling the support to take a step backward to allow the upward movement of a support and transport chair in an arc. A linear guide also offers the possibility of a design that is as flat as possible, which is advantageous for the reasons explained above.

[0016] In one embodiment, the holder can be locked to the base, both in the lower and upper positions. In the lower position, it is ensured that the holder remains at the same height even when the transport chair is removed from the holder. This firstly prevents the holder from springing upwards uncontrollably under force and secondly saves time when the transport chair needs to be hooked back into the holder. In the upper position, the locking mechanism ensures that even when driving over uneven ground, the holder and the transport chair inside cannot spring downwards and cause injury, but rather is secured in its upper position.

[0017] Additionally, it may advantageously be possible to lock the receptacle to the base in one or more intermediate positions located between the locking points for the lower and upper positions. If, for example, the vehicle is parked close to a curb and the transport chair is lowered not onto the roadway on which the vehicle is located, but rather onto the curb or sidewalk next to the vehicle, the receptacle, together with the transport chair located therein, may not be able to be lowered to the lowest position that would be structurally possible due to the design of the base and the receptacle. Accordingly, in such a case, the receptacle could not be locked to the base in the lowest position, i.e., at a lower locking point.One or more intermediate locking points near, but above, the lower locking point allow the support to be locked even when the vehicle is parked at an angle or in the aforementioned curb situation, and possibly even when the curbs are of different heights, if the support is lowered so far that the transport chair rests on the respective surface.

[0018] Additional intermediate locking points can be implemented, for example, in the middle area between the upper and lower locking points. This facilitates, for example, the handling of securing devices used to securely attach the transport chair to the mount. This is because the securing devices can be handled at a comfortable working height without having to manually hold the mount and transport chair against the action of a spring force. Especially when a large number of intermediate locking points are implemented, this type of handling of the securing devices is convenient and safe for people of different heights, and correspondingly requires minimal time.

[0019] In order to avoid having to provide a plurality of locking points individually on the base or on the holder by machining their components, in an economically advantageous embodiment a commercially available semi-finished product can be used which already provides a plurality of locking points, for example in the form of a perforated rail, in whose holes a locking element such as a locking bolt, a locking hook or the like can engage.

[0020] Locking the holder to the base means that the holder can be fixed at a specific height relative to the base. This can be achieved, on the one hand, by separate locking means, which can be designed, for example, in the form of an upright perforated rail and a spring-loaded locking bolt, so that the holder can be locked to the base at different heights by the locking bolt engaging a selected hole in the perforated rail. In another design, locking can be achieved by integrated locking means, for example, by the fittings used, which enable the spring force and / or the damping effect for the movement of the holder, having locking means.In this case too, one element of the fitting in question must be assigned to the base and another element of the same fitting to the receptacle, so that the receptacle can be locked to the base even when using such integrated locking means.

[0021] In one embodiment, the support has a lower platform on which the transport chair can be placed. This platform can extend across the entire width of the support, so that differently designed transport chairs can always be placed on the platform, regardless of their respective structural design. To save weight, the platform can be provided with one or more interruptions and, for example, be reduced to just one tongue located approximately in the middle of the width of the support, or it can be reduced to two tongues, so that the transport chair with its castors can be placed on these two platform tongues.

[0022] When inserting the transport chair into the holder, a simple, ergonomic movement and work sequence can be supported by the fact that the transport chair can be moved on at least two of its wheels even in its folded state, which is also possible with transport chairs known from practice. The above-mentioned platform, whether continuous or designed in the form of individual tongues, can therefore be dimensioned and arranged such that the wheels of the transport chair can be accommodated on the platform. In particular, if the holder is in its lower position either on the ground on which the vehicle equipped with the holder is standing, or if the holder is in its lower position a very short distance above the ground, the folded transport chair can - if necessary.by overcoming a small height, such as when driving over an obstacle or an edge of such a height - be driven onto the platform so that it does not need to be lifted.

[0023] In one embodiment, the holder has wheel recesses, namely upwardly open depressions which are designed to match the transport chair in terms of their dimensions and also their spacing from one another so that the transport chair's wheels can be inserted into the wheel recesses. The shape of the recess prevents unwanted and uncontrolled movement of the transport chair when its wheels are in the wheel recesses. This restricts the transport chair's mobility in a kind of rough fixation or pre-fixation if it is already so far into the holder that its wheels are in the wheel recesses. This rough or pre-fixation facilitates the subsequent steps in handling the transport chair when it is to be secured to the holder.

[0024] In one embodiment, the wheel recesses are not formed integrally by the holder itself, for example as folded sections of a sheet metal part, but rather as separate components, for example as molded parts made of plastic. In this way, the manufacturer of the holder can easily adapt the wheel recesses to differently designed transport chairs by mounting the matching wheel recesses on the holder during manufacture of the holder to suit the transport chair to be accommodated. In particular, if the wheel recesses are mounted on the holder in an interchangeable manner, e.g. using screws, the users of the holder can also adapt the holder accordingly by mounting the appropriate wheel recesses if, for example, a different model of transport chair is to be used.

[0025] Transport chairs known from practice have handles that run above the backrest of the transport chair and are height-adjustable so that they can be adjusted to the height of the person using the transport chair for optimal ergonomic handling. In one embodiment, the holder has a hook that is open at the top and serves to grip underneath the handle of a transport chair during use. In cases where the handle of the transport chair is height-adjustable, the transport chair does not have to be lifted and hung on the hook. In such cases, the transport chair can first be pushed onto the aforementioned platform and / or placed in the wheel recesses so that further handling of the transport chair can take place without the person in question having to lift the weight of the transport chair.Rather, with the handlebar raised, the transport chair's upper section can be pivoted toward the mount, using the castors as pivot bearings, so that the handlebar can then be lowered onto the upwardly open hook of the mount. The transport chair is now temporarily secured to the mount.

[0026] However, when the rescue vehicle is in motion, lifting forces could act on the transport chair, causing the handle to slip out of the hook. Therefore, the mount preferably includes additional securing means to securely attach the transport chair to the mount. In one embodiment, a retaining strap is arranged on the mount or connectable to the mount for this purpose, so that the transport chair can be secured to the mount using the retaining strap and is fixed in all directions of movement.

[0027] Similar to the wheel recesses described above, in one design of the bracket, the hook is also designed as a separate component. The bracket manufacturer can therefore tailor both the hook and the wheel recesses to a specific transport chair type during production. The hook can also be mounted on the bracket in an interchangeable manner, as explained above for the wheel recesses. This allows users of the brackets to convert the existing brackets to suit the new transport chair type when purchasing a different type of transport chair by replacing the wheel recesses and / or the hook of the holder with elements tailored to the new transport chair type.

[0028] The invention further relates not only to the separate mount, but also to an arrangement comprising, first, the vehicle wall and, second, the mount secured to the vehicle wall. Such an arrangement represents an advantageous embodiment of a vehicle, for example, an ambulance or rescue vehicle. Alternatively, such an arrangement represents an advantageous embodiment of a vehicle component that can be supplied to the vehicle manufacturer by an external supplier during vehicle production.

[0029] The vehicle wall can, as already explained above, be part of the body of a vehicle or also be designed as a movable wall, e.g. as a movable body part in the form of a door, a flap or the like. In one embodiment, the vehicle wall represents part of a so-called horizontal fitting. The vehicle wall - and thus the horizontal fitting - is designed in such a way that the holder can assume two different positions in the horizontal direction and can be moved between these two positions. In order to be able to provide sufficient holding forces to carry the holder together with the transport chair accommodated therein, the arrangement in one embodiment has a plurality of individual horizontal fittings which together form the wall to which the base of the holder is held.

[0030] In the upper position, the holder is in a first rest position that is relatively deeper into the vehicle, for example within a storage compartment inside the vehicle. From this rest position, the holder can be moved using the horizontal fitting into a second use position that is relatively less deep into the vehicle. In the rest position, the holder is so deep inside the vehicle that the holder cannot be lowered from its upper position. In the rest position, the holder allows the vehicle to be driven. In the use position, however, the holder is less deep into the vehicle, so that the holder can be lowered from its upper position to its lower position.

[0031] In one embodiment, the horizontal fitting is designed as a scissor mechanism, so that the movement of the horizontal fitting and the bracket attached to it can actually occur in a horizontal direction. In another embodiment, the horizontal fitting is designed as a tilting fitting, so that the bracket is not only displaced horizontally, for example, but can also be tilted from a substantially vertically oriented rest position into an inclined position, in which the holder can be lowered relative to the base without collision, for example, without hitting the floor of the aforementioned storage compartment.

[0032] In one embodiment, the horizontal fitting has a support wheel so that the horizontal fitting does not have to absorb the forces exclusively to hold the holder together with the transport chair in the upper position. The support wheel runs on a support surface of the vehicle. For example, the floor of the above-mentioned storage compartment or another, essentially horizontal surface in the vehicle can form such a support surface, whereby, for example, a guide rail in which the support wheel runs can also represent such a support surface. The weight of the holder and the transport chair held therein can be at least partially diverted via the support wheel into the support surface, so that the horizontal fitting is correspondingly relieved.

[0033] The transport chair can also be part of such an arrangement, provided that it is accommodated in the holder's receptacle and is not "in use" outside the holder.

[0034] Embodiments of the invention are explained in more detail below using purely schematic representations. Fig. 1 a perspective view of a first embodiment of a holder with a transport chair set therein, wherein the holder receptacle is in its upper position, Fig. 2 a view similar Fig. 1 , with the holder in its lowered position, Fig. 3 and 4Views similar Fig. 1 and 2 , but without transport chair, Fig. 5 a view from below of the holder, Figs. 6 and 7 views from two different directions of a second embodiment of a holder, which is in its upper position and on a first embodiment of a horizontal fitting, Fig. 8 the arrangement of the Figs. 6 and 7, wherein the holder of the bracket is in its lower position, Fig. 9 and 10 views of an arrangement with a second embodiment of a horizontal fitting, and Fig. 11 and 12 views of an arrangement with a third embodiment of a horizontal fitting.

[0035] In Fig. 1 A holder 1 is shown in which a transport chair 2 is accommodated. The transport chair is commercially available, so its construction need not be discussed in detail, but only a few elements that are important in connection with the holder 1 will be mentioned.

[0036] The holder 1 has a receptacle 3, which in the illustrated embodiment is designed as a folded sheet metal piece provided with several perforations for weight reasons. In its lower area, the receptacle 3 forms a platform on which the transport chair 2 can be placed, whereby the platform is also essentially reduced to two tongues 4 for weight reasons. The tongues 4 are each provided with molded plastic parts, each forming a wheel recess 5 and being replaceably attached to the tongues 4. Wheels 6 of the transport chair 2 are accordingly secured against rolling away by being received in the wheel recesses 5.

[0037] At its upper end, the transport chair 2 has a height-adjustable handle 7, which extends in the form of an inverted U open at the bottom over the entire width of the transport chair 2. The handle 7 is located in Fig. 1in its lowered position, into which it has been lowered onto an upwardly open hook 8 of the holder 3. The hook 8 is also replaceably attached to the holder 3. Additional securing of the transport chair 2 to the bracket 1, specifically to the holder 3, is achieved using retaining straps that are not shown in the drawing. Three holes 9 in the holder 3 serve as attachment points to which the two retaining straps can be attached.

[0038] A handle 10 on the holder 3 serves to guide the holder 3 together with the transport chair 2 in a height-adjustable and controlled manner. A button 11 is also arranged on the handle 10. This button interacts with a locking mechanism to lock the holder 3 to a Fig. 1 to lock the only partially visible base 12 at a fixed height and to prevent a relative movement between the base 12 and the holder 3.

[0039] In Fig. 1The holder 3 is in its upper position. An upper edge 18 of the holder 3 rests against an upper edge of the base 12 from below. The base 12 is attached to a wall of a vehicle (not shown in the drawings) and is immovable relative to the wall. The vehicle wall can be, for example, the wall of a storage compartment in an ambulance or a door of an ambulance, so that the base 12 is movable at most together with the vehicle wall.

[0040] Fig. 2 shows the holder 1, with the base 12 retaining its position, but the holder 3 together with the transport chair 2 being lowered, and the holder 3 thus being in its lower position. The locking mechanism associated with the button 11 interacts in this lower position with second locking means of the base 12, so that the holder 3 is also locked vertically in the lower position.

[0041] It can be seen that, for weight reasons, both the holder 3 and the base 12 are designed in a skeleton construction and have several openings. Fig. 2 a spring 14 can be seen, which in the illustrated embodiment is designed as a gas spring, such springs 14 being arranged on both sides of the base 12. The springs 14 are in Fig. 2 deflected and strives to raise the downwardly lowered holder 3 again and guide it into its upper position. On the base 12, locking means 15 are visible, which serve to interact with the locking mechanism of the holder 3 when the holder 3 is in its upper position. For this purpose, the locking means 15 have a locking pin 16. In the illustrated embodiment, two springs 14 are arranged in series on each side in order to enable a correspondingly large adjustment range of the holder 3 relative to the base 12.

[0042] Deviating from the illustrated embodiment, one of the two lateral springs 14 can be omitted and replaced by a telescopic damper, so that the upward movement of the support 3 occurs at a limited speed. If the telescopic damper has comparable dimensions to the spring 14 it replaces, the telescopic damper can be connected to the same attachment points as this spring 14. Furthermore, the upward movement of the support 3 can be damped by means of one or more rotary dampers. Fig. 3 shows the bracket 1 in a situation like in Fig. 1 , but without the transport chair 2. The base 12 located behind the holder 3 is visible, and due to the openings in the holder 3, Fig. 3also lower locking means 15 on the base 12 can be seen, again with a locking pin 16, with which lower locking means 15 the locking mechanism of the receptacle 3 cooperates when the receptacle 3 is lowered relative to the base 12 and is in its lower position.

[0043] Fig. 4 shows in a representation similar Fig. 3 the bracket 1 in a situation like in Fig. 2 However, the handle 10 and its button 11 are in Fig. 4 purely exemplary, they are shown detached from the holder 3 and interact with the upper locking means 15 of the base 12. In practice, contrary to this exemplary representation, the handle 10 and the button 11 are located on the holder 3, so that by means of the locking mechanism the holder 3 can be fixed to the lower locking means 15 of the base 12 when the holder 3 is positioned as in Fig. 4 shown in its lower position relative to the base 12.

[0044] Fig. 5 shows the bracket 1 from below. It is clear that the two tongues 4 are connected by a narrow web 17, so that the tongues 4 and the web 17 together form the platform at the lower end of the holder 3. Three screws in each tongue 4 serve to fasten the plastic molded part to the tongue 4, which forms the respective wheel recess 5. The aforementioned upper edge of the holder 3 is in Fig. 5 marked 18. It can be seen that the upper edge of the base 12 does not extend forward - in Fig. 5 i.e. towards the upper edge of the image - protrudes beyond the upper edge 18 of image 3.

[0045] The Figs. 6 and 7show, from two different perspectives, a second embodiment of a holder 1 as part of an arrangement which also includes a movable vehicle wall 19 supporting the holder 1. In this embodiment, the holder also includes a receptacle 3 for the transport chair, wheel recesses 5, and a base 12.

[0046] Unlike a door or flap in the body of a vehicle, the movable vehicle wall 19 in the embodiment of the Figs. 6 and 7designed as a component of a horizontal fitting 20. The horizontal fitting 20 enables the holder 1 to be moved horizontally. By means of the horizontal fitting 20, the holder 1 can be arranged so deep within the body of a vehicle that the receptacle 3 could not actually be lowered downwards from its upper position relative to the base 12 of the holder 1 because an interfering contour of the vehicle would prevent such movement. Such an interfering contour in the vehicle can, for example, be in the form of a floor, e.g. a vehicle floor, or in the form of the shelf of a storage compartment. When the horizontal fitting is in its rest position, the holder 1 is immersed so deeply into the vehicle that the aforementioned movement of the receptacle is not possible. The horizontal fitting 20 is brought into the rest position, for example, when the vehicle is to be driven.

[0047] By means of the horizontal fitting 20, the holder 1 can be displaced in the horizontal direction such that the holder 1 penetrates less deeply into the vehicle than in the rest position, so that the receptacle 3 can be lowered downwards past the interfering contour of the vehicle when the horizontal fitting 20 has been displaced from a rest position into a use position. Figs. 6 and 7 the horizontal fitting 20 is in its position of use, in which the lowering of the holder 3 is possible, but the holder 3 is shown in its upper position.

[0048] The horizontal fitting 20 of the Fig. 6is designed as a tilting fitting in which the vehicle wall 19 is articulated to supports 22 via joints 21, so that the horizontal fitting 20 is movable similar to a folding ladder. In its rest position, the vehicle wall 19 dips between the supports 22, with these elements then being aligned almost vertically. In the illustrated position of use, both the vehicle wall 19 and the supports 22 are inclined and are arranged essentially in an A-shape. At their lower ends, the supports 22 are articulated to floor fittings 23, which are fixed to a floor - or, if aligned differently, optionally also to a rear wall - within the vehicle. During the movements of the horizontal fitting 20 between its rest and its use position, the movable vehicle wall 19 is supported by a support wheel 24 on the aforementioned floor of the vehicle, to which the floor fittings 23 are fastened.

[0049] Fig. 8shows the arrangement of the Figs. 6 and 7 also with the horizontal fitting 20 in its position of use. In contrast to Figs. 6 and 7 the receptacle 3 of the bracket 1 is in its lower position and projects downwards well below the support wheel 24, whereby the support wheel 24 is still supported on a floor of the vehicle.

[0050] The Figs. 9 and 10 show an arrangement with a second embodiment of a horizontal fitting 20, which in this case is designed as a scissor mechanism. The movable vehicle wall 19, to which the holder 1 is mounted, can be removed via articulated struts 25 in the horizontal direction from support rails 26 fixedly mounted in the vehicle, either into the illustrated use position or brought into a rest position in which the vehicle wall 19 is closer to the support rails 26 than in the use position. In the use position, the receptacle 3 can be moved from its Fig. 9shown upper position into the Fig. 10 The lower position shown in the figure is shown as an example. Figs. 9 and 10 No support wheel is shown on the horizontal fitting 20. Deviating from the illustrated embodiment, the arrangement can also be provided with such a support wheel in this case, which can be attached, for example, to the base 12 of the holder 1 or to the vehicle wall 19.

[0051] The Figs. 11 and 12 show an arrangement with a third embodiment of a horizontal fitting 20, which in this case is designed as a telescopic fitting. The horizontal displacement of the holder 1 in this case does not occur transversely to the plane of the base 12 or the receptacle 3, as in the embodiments of Fig. 6 to 10, but rather transversely thereto, namely in the respective plane of the base 12 or the holder 3, so that the carrying chair together with the holder 1 can, for example, be pushed sideways into or pulled out of a narrow storage compartment of a vehicle. The movable vehicle wall 19, to which the holder 1 is mounted, is guided horizontally in support rails 26, which are permanently mounted in the vehicle. Fig. 11 shows the horizontal fitting 20 in its rest position and the bracket 1 accordingly in its upper position.

[0052] Fig. 12 shows that the horizontal fitting has been extended from this rest position into the illustrated use position. In this use position, the bracket 1 protrudes from the vehicle, so that, as shown in Fig. 12 shown, the receptacle 3 of the holder 1 has been lowered from the upper to the lower position. The movable vehicle wall 19 comprises Fig. 12both two pull-out rails, which are guided telescopically in the two support rails 26, as well as a plate element that is arranged between the two pull-out rails. In this embodiment, the Figs. 11 and 12 no support wheel is shown on the horizontal fitting 20, although in this case too, the base 12 of the holder 1 or the vehicle wall 19 can run over such a support wheel on a corresponding support surface of the vehicle.
