Description

Title of the invention: Set of stackable wheelchairs technical field

[0001] The present invention relates to a set of stackable wheelchairs comprising a plurality of chairs stackable one on top of the other, each of the chairs comprising a seat having at least two removable side wheels mounted by means of a removable side wheel axle, side armrests forming a stacking support for an identical chair to be stacked on the support, a stacking opening located under the seat and whose shape corresponds to that of the stacking support. Previous technique

[0002] Various types of wheelchairs are known, most often used to facilitate the mobility of people with reduced mobility. There are also wheelchairs designed for sports, allowing these same people to practice their favorite sports under the best possible conditions. Such wheelchairs are usually configured to form sets or groups corresponding, for example, to the number of members of a sports team. These sets or groups often need to be stored and moved, for example, between two sports competition venues. Various wheelchair stacking solutions exist to facilitate both storage and the moving and transport phases.

[0003] For example, document WO2006026810 describes a molded wheelchair comprising a rear section, a seat section, and rear axle supports, configured so that the molded structural body can be stacked by means of an interlocking interlocking system with a similar body. This facilitates the stacking and storage of the wheelchairs. The resulting stacks can contain several wheelchairs. However, these stacks are not secure and may collapse or fall, particularly during transport. Furthermore, the wheels and various wheelchair components must be stored and / or transported separately, with the risk of parts being lost.

[0004] To overcome these various drawbacks, the invention provides various technical means. Summary of the invention

[0005] First of all, a first objective of the invention is to provide a set of stackable chairs minimizing the risk of falls and facilitating the transport of stacked chairs.

[0006] Another objective of the invention is to provide a set of stackable armchairs allowing not only the body of the armchairs, but all the parts to be stored, without risk of loss of armchair parts.

[0007] To this end, the invention provides for a set of stackable wheelchairs comprising a plurality of wheelchairs stackable one on top of the other, each of the wheelchairs comprising:

[0008] -a seat comprising at least two removable side wheels mounted using a removable side wheel axle, side armrests forming a stacking support for an identical chair to be stacked on the support, a stacking opening located under the seat and whose shape corresponds to that of the stacking support;

[0009] -the stacking support comprising two lateral support holes;

[0010] -the lateral edges of the seat base each having a lateral locking hole;

[0011] -the lateral support holes and the lateral locking holes being aligned and forming a locking alignment when two chairs of the assembly are stacked, so as to allow the insertion of a wheel axle into the locking alignment to lock the assembly of the two stacked chairs.

[0012] This arrangement secures a stack of chairs in the storage position to prevent them from falling. A secured stack can also be easily moved simply by tilting it, without risk of accident, greatly facilitating stacking operations. Thus, the wheel axles have a dual function: they attach the removable wheels to the sides of the chair and lock the chairs in the stacked position.

[0013] This second function also makes it possible to avoid losing the wheel axles once they have been removed to make the piles.

[0014] Advantageously, the wheel axles and the lateral support holes form a hook.

[0015] This arrangement allows, for example, the disassembled wheels to be hung on the sides of a stack by placing them in bags with flexible handles positioned under the hooks. This provides a third function for the wheel axles.

[0016] The invention also provides for a wheelchair for a set of wheelchairs as previously described. Brief description of the drawings

[0017] All implementation details are given in the following description, supplemented by Figures 1 to 5, presented solely for the purpose of non-limiting examples, and in which: Fig. 1

[0018] [Fig.1] [Fig.1] is a front view of an example of a stack of armchairs nested one on top of the other; Fig. 2

[0019] [Fig.2] [Fig.2] is an enlarged view of the means used to secure the wheelchairs stacked; Fig.3

[0020] [Fig.3] [Fig.3] is a perspective view of the set of armchairs in [Fig.1]; Fig. 4

[0021] [Fig.4] [Fig.4] shows a front view of an example of an armchair ready for assembly front wheels for use; Fig. 5

[0022] [Fig. 5] [Fig. 5] illustrates an example of a method of storing wheels on a wheelchair in a suitably sized bag. Description of the implementation methods

[0023] Figure 4 shows an example of a chair enabling the implementation of the chair assembly concept described later. The chair 1 comprises a seat 2 whose mobility is ensured by two removable lateral wheels 3, each mounted by means of a removable lateral wheel axle 4, and support wheels 12, in this example, mounted under the seat 2. The removable lateral wheel axles 4 are mounted by insertion into lateral wheel bores 11 provided on the sides of the seat 2.

[0024] Identical armchairs can easily be stacked on top of each other, on the one hand thanks to lateral armrests 5 which form a stacking support 6 for an identical armchair to be stacked on this support, and on the other hand thanks to a stacking opening 7 located under the seat 2 and whose shape is either similar to or compatible with the profile of the stacking support 6 to allow stacking by interlocking the upper seat on the one below.

[0025] An example of a stack made up of such armchairs is shown in Figures 1 and 3, with an enlarged view of the elements allowing the securing of the stacked armchairs in [Fig.2],

[0026] The stacking support 6 of the chair in the lower position has two lateral support holes 8, one on each side of the chair.

[0027] The lateral edges of the base of the chair in the upper position each have a lateral locking hole 9.

[0028] As clearly seen in [Fig.2], when two chairs are stacked one on top of the other, the lateral support holes 8 and the lateral securing holes 9 are aligned and form a locking alignment 10. This locking alignment 10 allows the insertion of a wheel axle 4 to lock the assembly of the two stacked chairs.

[0029] As shown in [Fig. 5], the lateral support holes 8 on a single chair or on a chair placed on top of a stack can be used to form a hook 13 by inserting a wheel axle 4 into them. This hook 13 allows the handles 15 of a bag 14 in which the lateral wheels 3 of one or more chairs are stored to be retained. List of reference signs
