Description

Technical Field

[0001] This utility model relates to the field of oxygen cylinder storage for folding wheelchairs, specifically an oxygen cylinder storage rack for folding wheelchairs. Background Technology

[0002] Some patients require oxygen inhalation via oxygen cylinders during wheelchair transport. Oxygen cylinders are heavy, making them difficult to hold and requiring constant movement around the wheelchair. While many current wheelchairs are foldable, taking up little space and easy to store, securing them in place can be inconvenient, necessitating family members to hold the oxygen cylinders. Therefore, designing foldable oxygen cylinder holders for foldable wheelchairs to make the process easier for family members is a pressing issue for professionals in this field. Utility Model Content

[0003] The purpose of this utility model is to provide an oxygen cylinder storage rack for folding wheelchairs to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a folding wheelchair oxygen cylinder storage rack, comprising two base plates installed on the back of the chair, the two base plates being hinged together for folding and storage and maintaining front-to-back balance, and a horizontal mounting plate provided on the left end of the base plates, wherein a left-extending support mechanism for placing oxygen cylinders is hinged to the upper right side of the mounting plate, the support plate providing support and facilitating the support mechanism to rest on it, but not being too long or too wide to avoid occupying too much space when stored, and the support mechanism can be folded clockwise to fit against the back of the chair, and also including an oxygen cylinder holding mechanism provided on the lower side of the support mechanism for holding oxygen cylinders.

[0005] Preferably, the support mechanism includes a semi-circular support plate hinged to the mounting plate, with the two support plates forming a circle to facilitate the placement of the oxygen cylinder, and the support plate resting on the mounting plate to provide support, with a diameter larger than the diameter of the oxygen cylinder.

[0006] Preferably, the holding mechanism includes a soft pull strap connected to the lower side of the support plate, and the lower ends of the two pull straps are connected by a tray supporting the oxygen cylinder. The pull straps can be wider or semi-cylindrical, and the two together form a tube shape and can be folded. The tray can be soft or hard. When it is hard, it should be folded sideways and not too deep.

[0007] Preferably, the tray and the pull strap are made of the same material, both of which are made of cloth, which is soft and easy to store.

[0008] Preferably, it also includes a fixing mechanism disposed between the support plate and the chair back to fix the folded support plate, preventing the folded support plate from sagging and loosening, and is fixed by the fixing mechanism.

[0009] Preferably, the fixing mechanism includes a female Velcro strap on the support plate and a male Velcro strap on the chair back, which are glued together for fixation.

[0010] Preferably, at least two hinges are provided vertically to maintain vertical balance on the front and rear sides.

[0011] Preferably, the width of the support plate gradually increases from the end to the mounting plate, resulting in better strength and stability.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When unfolded, the support plate is flipped counterclockwise and placed on the mounting plate. The mounting plate supports the support plate. The two support plates are circular. The oxygen cylinder is placed directly in and then falls into the tray on the lower side for support and fixation, thus avoiding the need to hold it and making it easier. When not in use, first fold the support plate upward to fit against the back of the chair. Then, when the wheelchair is folded in half, the two base plates are folded back and forth. The straps and tray are made of soft material and are sandwiched in the middle for easy storage and carrying.

[0014] 2. The inclusion of both female and male hook and loop fasteners facilitates the securing of the support plate after folding. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution for a folding wheelchair oxygen cylinder storage rack: A folding wheelchair oxygen cylinder storage rack includes two base plates 1 installed on the back of the chair. The base plates 1 increase the support area, resulting in less force per unit area. The two base plates 1 are hinged together by hinges 2 to facilitate folding and storage and maintain front-rear balance. At least two hinges 2 are provided vertically to maintain vertical and front-rear balance. A horizontal mounting plate 3 is provided on the left end of the base plate 1. The upper right side of the mounting plate 3 is hinged to a left-extending support mechanism for placing oxygen cylinders. The support plate 4 provides support, allowing the support mechanism to rest on it, but it should not be too long or wide to avoid taking up too much space when folded. The support mechanism can be folded clockwise to fit snugly against the back of the chair. It also includes an oxygen cylinder holding mechanism located below the support mechanism to hold the oxygen cylinder.

[0023] The support mechanism includes a semi-circular support plate 4 hinged to the mounting plate 3. The two support plates 4 form a circle between them to facilitate the insertion of the oxygen cylinder, and the support plate 4 rests on the mounting plate 3 to provide support. Its diameter is larger than that of the oxygen cylinder. The width of the support plate 4 gradually increases from its end towards the mounting plate 3, resulting in better strength and stability.

[0024] The holding mechanism includes a soft pull strap 5 connected to the underside of the support plate 4, and the lower ends of the two pull straps 5 are connected by a tray 6 that supports the oxygen cylinder. The pull straps 5 can be wide or semi-cylindrical; together, they form a tube shape and are foldable. The tray 6 can be soft or hard; when hard, it should be folded sideways for storage and should not be too deep. The tray 6 and pull straps 5 are made of the same material, fabric, which is soft and easy to store.

[0025] It also includes a fixing mechanism disposed between the support plate 4 and the chair back to secure the folded support plate 4, preventing it from sagging or loosening after folding. The fixing mechanism includes a female Velcro strap 7 on the support plate 4 and a male Velcro strap 8 on the chair back, which are glued together for fixation.

[0026] Working principle: When unfolded, the support plate 4 is flipped counterclockwise and placed on the mounting plate 3. The mounting plate 3 supports the support plate 4. The two support plates 4 are circular. The oxygen cylinder is placed directly in and then falls into the tray 6 on the lower side for support and fixation, thus avoiding the need to hold it and making it easier. When not in use, the support plate 4 is first folded upward to fit against the back of the chair. Then, when the wheelchair is folded in half, the two base plates 1 are folded back and forth. The strap 5 and the tray 6 are soft and sandwiched in the middle for easy storage and carrying.

[0027] The female hook and loop fastener 7 and the male hook and loop fastener 8 are designed to facilitate the fixing of the support plate 4 after folding.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
