Description

Technical Field

[0001] This invention relates to the field of wheelchair storage equipment technology, and more particularly to a wheelchair storage device. Background Technology

[0002] Many people in society have limited mobility, especially in public service areas such as hospitals and nursing homes, where wheelchairs are needed for greater freedom of movement. If wheelchairs are deployed in large numbers, and demand is low, it could easily over-occupy public areas of hospitals, thus affecting daily medical and nursing activities. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of the present invention is to provide a wheelchair storage device that makes wheelchair storage convenient, easy to access, and does not occupy the ground.

[0004] To address the aforementioned technical problems, this invention provides a wheelchair storage device, comprising a wall-mounting device fixing frame, a swing connecting frame, and a storage rack for storing and placing a wheelchair. The device fixing frame is equipped with a traction device for controlling the swinging movement of the swing connecting frame. The storage rack is connected to the swing connecting frame to move in accordance with the swinging movement of the swing connecting frame, thereby changing its height.

[0005] The storage rack includes a base frame for supporting the wheelchair and booms on both sides of the base frame; the swing connecting frame includes a cantilever for suspending the storage rack and a connecting arm hinged to the device fixing frame. One end of the cantilever is connected to the connecting arm, and the other end is hinged to the boom, so that when the connecting arm is swung by the traction device, the base frame remains in a horizontal position.

[0006] As an improvement to the above solution, the traction device includes a take-up shaft, a traction belt, and a take-up drive mechanism for driving the take-up shaft to rotate. The device fixing frame is provided with a take-up shaft mounting seat for mounting the take-up shaft.

[0007] One end of the traction belt is connected to the take-up shaft, and the other end is connected to the swing connecting frame. The take-up drive mechanism controls the up-and-down swing of the swing connecting frame by driving the rotation of the take-up shaft.

[0008] As an improvement to the above solution, the device fixing frame includes a wall frame for connecting to the wall and a transverse extension beam for hinged to the connecting arm. The transverse extension beam is located at the bottom of the wall frame so that an equipment space for accommodating the traction device is formed above the transverse extension beam.

[0009] As an improvement to the above solution, the wall frame is provided with transverse extension beams on both sides of its bottom, and the connecting arms are respectively hinged to them.

[0010] A connecting crossbar connects the two connecting arms. The winding drive mechanism is located at a preset position in the equipment space. After the connecting arms swing to a preset angle, the connecting crossbar abuts against the winding drive mechanism.

[0011] As an improvement to the above solution, one end of the cantilever is provided with a pivot for hinged connection with the storage rack;

[0012] The storage rack includes a base frame for supporting a wheelchair and booms on both sides of the base frame. One end of the boom is hinged to the pivot, and the other end is connected to the base frame.

[0013] As an improvement to the above solution, the base frame includes a railing and a base for supporting the wheelchair, wherein the railing is provided at a predetermined position on the edge of the base to limit the movement of the wheelchair on the base.

[0014] As an improvement to the above solution, the base includes multiple base rods, the two ends of which are respectively connected to the two inner sides of the fence. The fence is provided with an entrance and exit for wheelchairs to enter and exit the base.

[0015] A preset distance is left between adjacent base rods to form a locking mechanism for defining the position of the wheelchair wheels.

[0016] As an improvement to the above solution, the connecting arm is provided with a device movement channel, and a first magnetic object is provided in the locking area of ​​the device movement channel. The base frame is provided with a second magnetic object for attracting the first magnetic object. When the connecting arm swings to the maximum storage angle position, the first magnetic object and the second magnetic object attract each other to limit the swing of the storage rack.

[0017] As an improvement to the above solution, the device fixing frame is provided with an unlocking line of a preset length, and the device moving channel is provided with a steering wheel. One end of the unlocking line is connected to the device fixing frame, and the other end passes around the steering wheel and is connected to the first magnetic object to suspend the first magnetic object.

[0018] As the connecting arm swings outward from its maximum retracted angle position, the first magnetic object gradually detaches from the locking area.

[0019] As an improvement to the above solution, the pivot is provided with a damping sleeve to reduce the back-and-forth swing of the boom. The damping sleeve is sandwiched between the boom and the cantilever to increase the movement resistance of the boom.

[0020] Implementing this invention has the following beneficial effects:

[0021] This invention discloses a wheelchair storage device, including a wall-mounting device fixing frame, a swing connecting frame, and a storage rack for storing and placing wheelchairs. The device fixing frame is equipped with a traction device for controlling the swinging movement of the swing connecting frame. The storage rack is connected to the swing connecting frame so that it moves with the swinging movement of the swing connecting frame to change height. Therefore, when it is necessary to retrieve or place a wheelchair, the swing connecting frame can be driven to tilt downwards so that the storage rack can be lowered to the ground for people to place or retrieve the wheelchair.

[0022] Furthermore, the storage rack includes a base frame for supporting the wheelchair and booms on both sides of the base frame; the swing connecting frame includes a cantilever for suspending the storage rack and a connecting arm hinged to the device fixing frame. One end of the cantilever is connected to the connecting arm, and the other end is hinged to the boom, so that when the connecting arm is swung by the traction device, the base frame remains in a horizontal position, thereby preventing the wheelchair from falling out of the storage rack due to gravity during the folding process. Attached Figure Description

[0023] Figure 1 This is a schematic diagram of the wheelchair storage device of the present invention;

[0024] Figure 2 This is a cross-sectional structural schematic diagram of the wheelchair storage device of the present invention. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] See Figure 1 , 2 This invention provides a wheelchair storage device, including a wall-mounting device fixing frame 1, a swing connecting frame 2, and a storage rack 3 for storing and placing a wheelchair. The device fixing frame 1 is provided with a traction device 4 for controlling the swinging movement of the swing connecting frame 2. The storage rack 3 is connected to the swing connecting frame 2 so as to move with varying heights following the swinging movement of the swing connecting frame 2.

[0027] The storage rack 3 includes a base frame 31 for supporting the wheelchair and hanging arms 32 on both sides of the base frame 31; the swing connecting frame 2 includes a cantilever 21 for suspending the storage rack 3 and a connecting arm 22 hinged to the device fixing frame 1. One end of the cantilever 21 is connected to the connecting arm 22, and the other end is hinged to the hanging arm 32, so that when the connecting arm 22 is driven by the traction device 4 to swing, the base frame 31 remains in a horizontal position.

[0028] Specifically, the traction device 4 includes a take-up shaft 41, a traction belt 42, and a take-up drive mechanism 43 for driving the take-up shaft 41 to rotate. The device fixing frame 1 is provided with a shaft mounting seat 11 for mounting the take-up shaft 41. The take-up drive mechanism 43 includes a gearbox for driving the take-up shaft and a motor for driving the gearbox.

[0029] One end of the traction belt 42 is connected to the take-up shaft 41, and the other end is connected to the swing connecting frame 2. The take-up drive mechanism 43 controls the up-and-down swing of the swing connecting frame 2 by driving the rotation of the take-up shaft 41.

[0030] Therefore, when it is necessary to retract the storage rack 3 upwards, the connecting arm 22 can be swung upwards by winding the traction belt 42, thereby lifting the storage rack 3 upwards. Correspondingly, when it is necessary to lower the storage rack 3, simply release the traction belt 42, and the storage rack 3 can gradually fall to the ground under the action of gravity.

[0031] The device mounting frame 1 includes a wall frame 12 for connecting to a wall and a transverse extension beam 13 for hinged to the connecting arm 22. The transverse extension beam 13 is located at the bottom of the wall frame 12 so that an equipment space for accommodating the traction device 4 is formed above the transverse extension beam 13.

[0032] The wall frame 12 has transverse extension beams 13 on both sides of its bottom, and each beam is hinged to a connecting arm 22. A connecting crossbar 23 connects the two connecting arms 22. The winding drive mechanism 43 is located at a preset position in the equipment space. After the connecting arm 22 swings to a preset angle, the connecting crossbar 23 abuts against the winding drive mechanism 43, similar to abutting against a gearbox. Correspondingly, this preset angle is the maximum storage angle.

[0033] Therefore, by limiting the contact between the connecting crossbar 23 and the winding drive mechanism 43, it is ensured that the overall center of gravity between the storage frame 3 and the swing connecting frame 2 is outward relative to the hinge between the connecting arm 22 and the transverse extension beam 13. This ensures that the connecting arm 22 can always maintain an outward tilting swing tendency by utilizing the weight of the storage frame 3, thereby ensuring the unwinding operation of the traction device 4.

[0034] One end of the cantilever 21 is provided with a pivot 24 for hinged to the storage rack 3; the storage rack 3 includes a base frame 31 for supporting a wheelchair and a boom 32 provided on both sides of the base frame 31, one end of the boom 32 is hinged to the pivot 24, and the other end is connected to the base frame 31.

[0035] The base frame 31 includes a railing 311 and a base for supporting a wheelchair. The railing 311 is provided at a predetermined position on the edge of the base to limit the movement of the wheelchair on the base.

[0036] Furthermore, to restrict the movement of the wheelchair on the base, the base includes multiple base rods 312, with each end of a base rod 312 connected to the inner sides of a guardrail 311. The guardrail 311 has an inlet / outlet 313 for the wheelchair to enter and exit the base. A predetermined distance is left between adjacent base rods 312 to form a locking slot 314 for limiting the position of the wheelchair wheels. Therefore, by locking the wheelchair wheels into the locking slot 314, the free sliding of the wheelchair on the base can be restricted.

[0037] On the other hand, to prevent the storage rack 3 from swinging due to unexpected external interference when in the storage state, such as strong winds or minor accidental collisions in extreme situations, the connecting arm 22 is provided with a device movement channel 221. A first magnetic object 5 is provided in the locking area of ​​the device movement channel 221, and the base frame 31 is provided with a second magnetic object 6 for attracting the first magnetic object 5. When the connecting arm 22 swings to the maximum storage angle position, the first magnetic object 5 and the second magnetic object 6 attract each other to limit the swing of the storage rack 3.

[0038] Furthermore, in order to maximize the attraction between the first magnetic object 5 and the second magnetic object 6 while avoiding excessive attraction that would prevent the storage rack 3 from separating them due to gravity, the device fixing frame 1 is equipped with an unlocking line 7 of a preset length. A steering wheel 222 is provided within the device's movable channel 221. One end of the unlocking line 7 is connected to the device fixing frame 1, and the other end passes around the steering wheel 222 and connects to the first magnetic object 5 to suspend it.

[0039] When the connecting arm 22 swings outward from its maximum storage angle position, the distance between the connecting arm 22 and the device fixing frame 1 will gradually increase, causing the unlocking line 7 to lift the first magnetic object 5. The first magnetic object 5 gradually separates from the locking area, thereby causing the first magnetic object 5 and the second magnetic object 6 to be misaligned, and finally achieving separation.

[0040] Preferably, the rotating shaft 24 is fitted with a damping sleeve 8 to reduce the back-and-forth swing of the boom 32. The damping sleeve is sandwiched between the boom 32 and the cantilever 21 to increase the resistance to movement of the boom 32. Preferably, the damping sleeve is a rubber sleeve. This arrangement can solve the problem of high-frequency oscillation in the storage rack 3.

[0041] Preferably, the device fixing frame 1 is provided with a fall arresting rope to prevent the swing connecting frame from swinging excessively downward, and the fall arresting rope is connected to the swing connecting frame. More preferably, the device fixing frame is provided with a winding device for automatically winding the fall arresting rope. This winding device is prior art, and its technical principle can be referred to the rewinding device of existing common measuring tapes.

[0042] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
