Description

Technical Field

[0001] This utility model belongs to the field of wheelchair technology, and relates to a wheelchair, and more particularly to a weatherproof wheelchair. Background Technology

[0002] Currently, wheelchairs are frequently used to transport patients within hospitals, facilitating movement for patients with mobility difficulties or those with special needs between different buildings and departments. However, current wheelchairs are relatively simple, essentially just a combination of a seat and wheels, lacking a protective cover. In inclement weather, patients must either hold an umbrella themselves or have a family member hold one for them, which is extremely inconvenient. Designing a new type of wheelchair that protects users from rain and snow, is easy to operate, and has a stable structure is a pressing challenge we urgently need to overcome. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a weatherproof wheelchair. It solves the technical problem of how to shield a wheelchair from wind and rain while ensuring ease of use and structural stability.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A weatherproof wheelchair includes a wheelchair body and a rain cover, characterized in that the wheelchair body has a backrest, a support column is provided on the wheelchair body behind the backrest, a limiting gap is provided between the support column and the backrest, armrests are provided on both sides of the backrest, and a support component is fixed on the wheelchair body.

[0006] The rain cover includes a base frame formed by bending stainless steel strips into an arc structure. Several keel strips are connected to the base frame, and a cover is laid on the keel strips. A pin is fixed on the base frame at the position of the corresponding support plug. When the rain cover is installed on the wheelchair body, one side of the base frame is inserted into the limiting gap and the pin is engaged with the support plug.

[0007] The wheelchair of this application is equipped with a rain cover, which can be used to shield against wind and rain in extreme weather. The bottom of the rain cover is designed with a base frame formed by bending stainless steel strips, which has good structural strength. The base frame has a pin. The entire rain cover is snapped into place with the limiting gap on the seat through one side of the base frame, and then the pin and the receiving plug are engaged in a plug-in and plug-out engagement. This multi-point engagement and fixation not only facilitates disassembly and assembly, but also ensures connection stability and structural strength after installation, thereby achieving the purpose of shielding against wind and rain.

[0008] In the aforementioned weatherproof wheelchair, there are two support columns spaced apart, and each support column is fixed with a handle for gripping.

[0009] The wheelchair of this application has two support columns spaced apart on both sides, with the two columns corresponding to the two sides of the backrest. This way, when one side of the rain cover is inserted between the backrest and the rain cover, both ends of one side of the rain cover can be engaged, making the base of the rain cover fit more snugly with the backrest. This achieves the wheelchair's weatherproof capability while ensuring connection strength and stability.

[0010] The support column of this application is directly connected to a handle, which can be held by a person to push the wheelchair. The support column itself has good structural strength, which makes it easy for the person to push and exert force. It simplifies the structure of the wheelchair while ensuring strength.

[0011] In the aforementioned weatherproof wheelchair, two armrests are respectively installed corresponding to two support columns, and the ends of the armrests are welded to the sides of the corresponding support columns.

[0012] In the aforementioned weatherproof wheelchair, the base frame has a U-shaped structure with one side open and includes a limiting part and two abutment parts. The two abutment parts are spaced apart and correspond to the positions of the armrests respectively. When the rain cover is installed on the wheelchair body, the abutment parts abut against the upper surface of the armrests.

[0013] The armrests of this application are directly welded to the armrests so that the position of the armrests corresponds to the position of the uprights. In this way, when the limiting part on the base frame is inserted into the limiting gap, the abutment part just abuts against the upper surface of the armrest. The entire base frame just surrounds the seat position. During installation, the backrest acts as a guide, making it easy to align the position of the rain cover with the limiting gap and the supporting plug for installation and fixation. This allows the wheelchair to be protected from wind and rain while facilitating installation.

[0014] In the aforementioned weatherproof wheelchair, the latch has two pins, each located at one of the two abutment portions.

[0015] The design of multiple pins and support plugs makes the installation of the rain cover more stable and stronger. The multiple pins and support plugs are divided into two groups located on both sides, which can effectively prevent the rain cover from tilting and ensure the strength and stability after installation.

[0016] In the aforementioned weatherproof wheelchair, the connection between the backrest and the limiting part has an inner rounded corner to fit with the edge of the seat.

[0017] The connection between the abutment part and the limiting part of this application is designed with rounded inner corners. The rounded inner corners fit the outer contour of the chair back better, so that the overall rain cover will not wobble after installation and has better stability.

[0018] In the aforementioned weatherproof wheelchair, at least two keel strips are fixedly connected to the base frame near the limiting part, and at least two keel strips are hinged to the base frame near the abutment part. All the keel strips are bent upward to form an arch structure.

[0019] The rain cover of this application has a partially foldable and retractable feature. Specifically, the keel strip on one side of the base frame is designed as a rotatable structure. By rotating, it can be folded and stacked, so that the cover laid on the keel strip will also fold. This design allows the rain cover to adapt to more scenarios. When rain protection is needed, the rain cover can be flipped up for shielding, and when the user needs to walk on the road, it can be folded up. This design has better adaptability.

[0020] In the aforementioned weatherproof wheelchair, all the keel strips gradually decrease in size as they approach the limiting part.

[0021] The size of the keel strip in this application gradually decreases on the side near the limiting part. Since the keel strip on the side near the abutment part can rotate, the size of the keel strip on that side is larger. After rotation, it can be stacked with the smaller keel strip in a staggered manner, thus occupying less space.

[0022] In the aforementioned weatherproof wheelchair, the support component has a tubular structure and an inner hole, the pin has a columnar structure and a guide portion with a gradually decreasing diameter at its end, and the pin can be inserted into the inner hole and has a clearance fit with the inner hole.

[0023] In the aforementioned weatherproof wheelchair, the canopy is made of flexible transparent material such as PVC or PE.

[0024] Compared with existing technologies, the advantages of this product are as follows: This wheelchair is equipped with a rain cover, which can be used to shield against wind and rain in extreme weather. The bottom of the rain cover of this application is designed with a base frame formed by bending stainless steel strips, which has good structural strength. The base frame has a pin, and the entire rain cover is snapped into place with the limiting gap on the seat through one side of the base frame. Then, the pin and the connector are engaged in plug-in and plug-out cooperation. This design is convenient for disassembly and assembly, and ensures connection stability and structural strength after installation, thereby achieving the purpose of shielding against wind and rain.

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figure 1 and Figure 2 The illustrated weatherproof wheelchair includes a wheelchair body 1 and a rain cover 2. The wheelchair body 1 has a seat with a backrest 11. A support column 12 is located behind the backrest 11 on the wheelchair body 1, and a limiting gap 13 is provided between the support column 12 and the backrest 11. Armrests 14 are provided on both sides of the backrest 11 on the wheelchair body 1, and support inserts 15 are fixed on the armrests 14. The rain cover 2 includes a base frame 21 formed by bending stainless steel strips into an arc structure. Four keel strips 22 are connected to the base frame 21, and a film-like cover 23 is laid on the keel strips 22. Pins 24 are fixed on the base frame 21 at positions corresponding to the support inserts 15. When the rain cover 2 is installed on the wheelchair body 1, one side of the base frame 21 is inserted into the limiting gap 13, and the pins 24 and support inserts 15 are engaged. The insert 15 has a tubular structure with an inner hole, and the pin 24 has a columnar structure with a guide portion whose diameter gradually decreases at its end. The pin 24 can be inserted into the inner hole and is in clearance fit with the inner hole. The wheelchair of this application is equipped with a rain cover 2, which can be used to shield against wind and rain in extreme weather. The bottom of the rain cover 2 of this application is designed with a base frame 21 formed by bending stainless steel strips, which has good structural strength. The base frame 21 has a pin 24. The entire rain cover 2 is snapped into the limiting gap 13 on the seat through one side of the base frame 21, and then engaged with the insert 15 by the pin 24. This multi-point engagement and fixation not only facilitates disassembly and assembly, but also ensures connection stability and structural strength after installation, thereby achieving wind and rain protection.

[0030] Furthermore, the support columns 12 are two in number and spaced apart, each with a handle 16 fixed to it for gripping. The wheelchair of this application has two support columns 12 spaced apart on both sides, corresponding to the two sides of the backrest 11. This ensures that when one side of the rain cover 2 is inserted between the backrest 11 and the rain cover 2, both ends of one side of the rain cover 2 are engaged, making the base frame 21 of the rain cover 2 fit more snugly against the backrest 11. This achieves the wheelchair's weather protection capability while ensuring connection strength and stability. The handles 16 are directly connected to the support columns 12, allowing the user to grip and push the wheelchair. The support columns 12 themselves have good structural strength, facilitating pushing and ensuring strength while simplifying the wheelchair structure.

[0031] Furthermore, the two armrests 14 are respectively provided corresponding to the two support columns 12, and the ends of the armrests 14 are welded to the sides of the corresponding support columns 12. The base frame 21 has a U-shaped structure with one side open and includes a limiting part 211 and two abutment parts 212. The two abutment parts 212 are spaced apart and correspond to the positions of the armrests 14 respectively. When the rain cover 2 is installed on the wheelchair body 1, the abutment parts 212 abut against the upper surface of the armrests 14. In this application, the armrest 14 is directly welded to the support column, ensuring that the position of the armrest 14 corresponds to the position of the support column. This allows the limiting part 211 on the base frame 21 to engage with the limiting gap 13, so that the abutment part 212 abuts against the upper surface of the armrest 14. The entire base frame 21 completely surrounds the seat area, providing a guide-like function at the backrest 11 during installation. This facilitates easy alignment of the rain cover 2 with the limiting gap 13 and the support member 15 for installation and fixation, providing wind and rain protection for the wheelchair while ensuring convenient installation. Preferably, there are two pins 24, each located on one of the two abutment parts 212. The multiple pins 24 and support members 15 design makes the installation of the rain cover 2 more stable and stronger. Furthermore, the multiple pins 24 and support members 15, divided into two groups located on both sides, effectively prevent the rain cover 2 from tilting, ensuring strength and stability after installation.

[0032] Furthermore, the connection points between the abutment part 212 and the limiting part 211 both have inner rounded corners for fitting with the edge of the seat. The connection points between the abutment part 212 and the limiting part 211 in this application are designed with rounded inner rounded corners, which better fit the outer contour of the seat back 11, ensuring that the overall rain cover 2 will not wobble after installation and has better stability.

[0033] Furthermore, two keel strips 22 are fixedly connected to the base frame 21 near the limiting part 211, and two keel strips 22 are hinged to the base frame 21 near the abutment part 212. All keel strips 22 are bent upwards to form an arch structure. A portion of the rain cover 2 of this application is foldable and retractable. Specifically, one side of the keel strip 22 on the base frame 21 is designed as a rotatable structure, allowing it to be folded by rotation, thus stacking the keel strips 22. The canopy 23 laid on the keel strips 22 will also fold accordingly. This design allows the rain cover 2 to adapt to more scenarios; it can be flipped up to provide shelter from the rain when needed, and folded down when needed, resulting in better adaptability. Preferably, the dimensions of all keel strips 22 gradually decrease towards the side where the limiting part 211 is located. The size of the keel strip 22 in this application gradually decreases on the side near the limiting part 211. Since the keel strip 22 on the side near the abutment part 212 can rotate, the size of the keel strip 22 on that side is large. After rotation, it can be stacked with the smaller keel strip 22 in a staggered manner, thus occupying less space.

[0034] Preferably, the canopy 23 is made of flexible transparent PVC or PE material. Using such material can not only protect against wind and rain, but also allow family members behind to easily observe the user in the wheelchair, ensuring good safety.
