Example 1
As shown in fig. 1, 2 and 3, a foldable leg rest for a wheelchair includes a bracket 1, a rotating member 2, a support member 3, a footrest member 4 and a positioning member 5; the support 1 can be an independent support structure, the support 1 is a bent structure and extends upwards to the position below the wheelchair armrest, the support 1 can also be replaced by a front upright post of the wheelchair, no matter what type, the support 1 is used for connecting a leg rest, and the support 1 is fixedly provided with a limit stop 11; the rotating part 2 comprises a fixed structure and a rotating structure; the fixing structure is fixedly connected with the bracket 1 in a welding mode, and can also be fixedly connected in other modes such as screw fixation or integrated forming and the like during specific implementation; the rotating structure is rotationally connected with the fixed structure; then, the outer part of the rotating structure is wrapped with a shell fixed with the rotating structure, or other structures are not arranged on the outer part of the rotating structure, in short, the rotating structure with or without the shell is fixedly connected with the supporting part 3, wherein the fixed connection refers to fixed connection which is not convenient for relative position change, such as welding, screw connection or integral forming and the like; the support component 3 is fixedly or movably connected with the pedal component 4, the fixed connection can be in a welding mode, a screw connection mode or an integral forming mode and the like, and the movable connection can be hinged on a rotating shaft and can also be other foldable movable connections; the supporting component 3 is provided with a positioning hole near the tail end of the pedal component 4, the positioning component 5 is fixedly arranged below the bracket 1, and the positioning component 5 is of a telescopic structure; the positioning component 5 is matched with the positioning hole; when the leg rest is in a folding state, the leg rest can be fixedly positioned at the folding position by inserting the positioning part 5 into the positioning hole, so that the leg rest is prevented from being displaced to influence the use of the wheelchair; in specific implementation, the positioning hole is not necessarily arranged at the tail end of the pedal part 4, the positioning part 5 is not necessarily arranged below the bracket 1, and the technical purpose can be realized as long as the leg rest is matched with the positioning hole to fix the leg rest when the leg rest is in a folding state; when the leg rest is put down for use, the limit stop 11 is blocked below the supporting component, so that the supporting component 3 is prevented from continuously falling down, and the limiting effect can be achieved.
When the leg rest is needed, the leg rest can be put down for use; when the leg rest is not needed, the leg rest can be folded by rotating the supporting component 3 around the rotating component 2 and inserting the positioning component 5 into the positioning hole on the supporting component 3 when the pedal component 4 is positioned near the armrest of the wheelchair, and the use is very convenient.
On the basis of the basic model, the present embodiment can also be expanded in the following functions.
The rotating structure in the rotating part 2 can be provided with a bearing, and the rotating structure is connected with the fixed structure through the bearing, so that the rotating structure can rotate more flexibly; or the damping rotating shaft is used for the rotating part, and the damping rotating shaft is convenient to rotate and can have a limiting function, so that the leg rest can stay at any position where a user wants the leg rest to stop.
Wherein, the supporting component 3 can also be provided with an attached rod 32; a bent part 31 is arranged at the position of the supporting component 3, which is abutted against the limit stop 11; the attachment rod 32 is fixedly connected to the bent portion 31 by welding or screwing, which can increase the strength of the support member 3 and make the wheelchair leg rest more durable.
In addition, the first limit structure 62 can be fixedly arranged at the bent part 31 by welding or screwing and the like; first limit structure 62 includes the column stopper and sets up in the terminal elasticity anticollision structure of column stopper, and when the leg was by putting down the use, first limit structure 62 played the effect of optimizing spacing effect and anticollision between flexion 31 and limit stop 11.
Correspondingly, on the basis of the basic type and the extended type, the supporting component 3 is close to the tail end of the rotating component 2, and a second limiting structure 61 is fixedly arranged; the second limiting structure 61 comprises a 7-shaped or L-shaped limiting block; when the wheelchair leg rest rotates upwards to the side of the wheelchair armrest, the second limiting structure 61 is contacted with the limiting stop 11 to limit the wheelchair leg rest to further rotate backwards, so that the wheelchair leg rest is more convenient to fold; consider that sometimes the user receives to close and probably exert oneself too big when leaning on, the utility model discloses still designed and add the elasticity anticollision structure of establishing at 7 fonts or L shape stopper end, this anticollision structure can be rubber or flexible plastic etc to avoid taking place rigid collision between 7 font stoppers and the limit stop 11.
In addition, the two sides of the pedal plate part 4 can be provided with massage convex structures, when the leg rest is put down for use, a user can massage feet by the front side of the pedal plate; when the leg rest is folded to the armrest, the user can massage the hand by the back of the pedal.
In the above basic or various additional or modified embodiments, the footrest member 4 and the support member 3 may be fixedly connected immovably by welding, screwing, or the like, and at this time, when such legs are folded near the armrests, the back surface of the footrest member 4, that is, the surface that cannot be ridden when the leg rests are put down for use, may be used as a small table; if when using, feel two running-board parts 4 keep off in the front, this embodiment still provides a more convenient scheme, just namely pass through hinge joint with running-board part 4 and support component 3, lean on the receipts with the leg before, earlier near support component 3 is buckled to running-board part 4, then lift up support component 3 again, not only receive like this and close conveniently, still save space.
The positioning component in the embodiment can use a common bolt or a spring pin.
Example 2
A wheelchair in which a basic type or various additional and improved types of foldable leg rests for a wheelchair in example 1 are incorporated and used, and which naturally includes an aluminum alloy main frame, a seat cushion, a back cushion, armrests, etc. in addition to the leg rest in example 1; those skilled in the art can combine the leg rest of the present invention with the wheelchair of the prior art without creative labor, and the above structures and components can be installed and connected, so that the present solution is not described in detail.
Example 3
As shown in fig. 2 and 3, an electric wheelchair in which a foldable leg rest for a wheelchair of the basic type or various additional and improved types according to embodiment 1 is incorporated into the electric wheelchair for use naturally includes a seat main body, a motor, a controller, wheels, a battery, a charger, and the like; similar to the embodiment 2, the person skilled in the art can install and connect the electric wheelchair according to his/her own understanding without creative labor, and therefore the detailed description of the scheme is omitted.
After the utility model is installed according to the connection mode of the embodiment 1, 2 or 3, the legs can be turned down easily when the utility model is used; reasonable in design, the flexible operation is simple and convenient, and very big saving product storage space need not to dismantle product part, has reduced intensity of labour, has laborsaving, the advantage of saving time.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the spirit and scope of the invention.
