Description

Technical Field

[0001] The utility model relates to the field of barrier-free facilities, in particular to a foldable barrier-free bathing chair. Background Art

[0002] In the design of barrier-free facilities, bathing chairs are important auxiliary tools, especially for the elderly or people with limited mobility. Bathing chairs in the prior art usually do not have a folding function, especially bathing chairs with toilets, which causes them to take up a lot of space when not in use and are inconvenient to store. In addition, the armrests and seats of traditional bathing chairs do not have the function of linked folding, making the folding process of the chair cumbersome and inconvenient. Although some designs have achieved the linked folding of the chair legs and the seat, the armrests still need to be operated separately, such as the Chinese utility model patent with application number 2023234996388, entitled A Linked Folding Barrier-Free Bathing Chair. The structure of this armrest operating independently will increase the burden on the user. In order to solve this problem, there is a need for a bathing chair with a linked folding function and a toilet, and further able to solve the problem of armrest linkage. Summary of the invention

[0003] The utility model aims at the shortcomings of the prior art and provides a foldable barrier-free bathing chair.

[0004] To solve the above technical problems, the utility model is solved by the following technical solutions:

[0005] A foldable barrier-free bathing chair comprises a main chair leg frame, a secondary chair leg frame, a seat support frame, a first connecting member and a second connecting member. The main chair leg frame comprises a backboard support rod and a main chair leg rod, the secondary chair leg frame and the main chair leg rod are interlaced in an X shape, and the secondary chair leg frame is hinged to the main chair leg rod, and the rear end of the seat support frame is hinged to the main chair leg frame; one end of the first connecting member is connected to the seat support frame, and the other end is connected to the main chair leg frame or the secondary chair leg frame; one end of the second connecting member is connected to the secondary chair leg frame, and the other end is connected to the main chair leg frame; the bathing chair has at least a use state and a folded state. When the bathing chair is in the use state, the first connecting member supports the seat support frame, and the second connecting member limits the distance between the secondary chair leg frame and the main chair leg frame. The secondary chair leg frame and the main chair leg rod are interlaced in an X shape and hinged, which provides stability for the bathing chair and is easy to fold and store.

When the bathing chair is opened from the folded state to the use state, the angle between the two connecting rods increases from the minimum to the maximum. Through the design of at least two connecting rods, the bathing chair can be more smoothly converted between the use state and the folded state. When the shower gel is opened, the length of the two connecting rods can limit the opening angle of the bathing chair to avoid over-opening.

[0010] Preferably, the first connecting member is arc-shaped, and its two ends are respectively connected to the seat support frame and hinged to the auxiliary chair leg frame. The arc-shaped first connecting member provides better mechanical support and facilitates the folding of the seat support frame, so that the seat support frame and the auxiliary chair leg frame can be folded or opened in a linked manner.

[0011] Preferably, the back support rod and the main leg rod are connected via a bent connection portion, and the seat support frame is connected to the bent connection portion. The design of the bent connection portion makes the connection between the back support rod and the main leg rod more stable and facilitates the folding of the overall structure.

[0012] Preferably, a seat plate is fixedly mounted on the seat support frame, and a toilet is detachably mounted on the bottom of the seat plate. The detachable toilet on the seat plate provides convenient cleaning and maintenance.

[0013] Preferably, guide rails are arranged on the left and right sides of the bottom of the seat plate, and the two sides of the toilet bowl cooperate with the guide rails so that the toilet bowl can slide forward and backward relative to the seat plate. The guide rails at the bottom of the seat plate cooperate with the sliding design of the toilet bowl to improve the convenience of use.

[0014] Preferably, the seat plate is provided with a cover plate connected to the space inside the toilet bowl, and the outer end of the guide track limits the toilet bowl. The cover plate can be used as a cover when the bathing chair is used for bathing, and can be used as a toilet when the cover plate is opened. The outer end of the guide track can block the toilet bowl when the bathing chair is folded to prevent the toilet bowl from sliding out of the guide track.

[0015] The utility model has significant technical effects due to the adoption of the above technical solutions:

[0016] The utility model solves the problems of inconvenient storage and complicated operation of bathing chairs with toilet seats in the prior art through its innovative design. The X-shaped staggered chair leg design and hinged structure allow the bathing chair to be easily folded when not in use, saving space. The arc-shaped first connecting member and the second connecting member provide better mechanical support while simplifying the folding and unfolding process. The design of the armrests not only increases the comfort and safety of the user, but also its hinged and linked folding functions make the overall structure more compact. Overall, the bathing chair of the present invention has a stable structure, is easy to operate, and is easy to store, which greatly improves the practicality and user experience of the barrier-free bathing chair.
