Description

Technical Field

[0001] This utility model relates to the field of shower chair technology, and in particular to an adjustable height shower chair. Background Technology

[0002] As a bathroom aid for people with mobility impairments and the elderly, the height adjustability of a shower chair is a core function to adapt to different user body types, bathroom environments, and safety and comfort needs. Typically, shower chairs are used by the same user for extended periods, and the height adjustment function is not frequently used. However, most height-adjustable shower chairs on the market currently use a telescopic rod structure or a pre-drilled hole adjustment structure. This involves multiple sets of positioning holes on the support legs, with the seat height adjusted by nested sleeves and locking bolts. While this method is relatively simple in structure and operation, the segmented support legs or bolts are prone to corrosion and failure due to prolonged exposure to moisture, posing certain safety hazards and making it unsuitable for bathroom use. Therefore, there is an urgent need for a height-adjustable solution with a simple and stable structure. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an adjustable height shower chair, which has the characteristics of adjustable height and relatively simple and reliable structure.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An adjustable height shower chair includes a seat cushion and a support assembly disposed under the seat cushion. The support assembly includes an X-shaped support leg. The support leg includes two front-to-back first ends at the upper end and two front-to-back second ends at the lower end. A hinge point is provided between the first ends and the second ends. The first ends can rotate around the hinge point, and the two first ends can move closer to or further away from each other in the front-to-back direction.

[0006] The lower surface of the seat cushion is provided with a support recess that can be fixedly engaged with the first end. There are at least two sets of support recesses. Each set of support recesses includes two mating grooves arranged in front and behind. When the first end engages with different sets of support recesses, the vertical distance between the first end and the second end in the vertical direction can be adjusted.

[0007] The supporting recess includes a set of first grooves arranged front to back and a set of second grooves arranged front to back. The distance between the first grooves is L1, and the distance between the second grooves is L2. <L2。

[0008] The support legs are two in number and are arranged on the left and right sides under the seat cushion. A crossbar is connected between the first ends of the front and rear of the two support legs, and the crossbar can cooperate with the first groove or the second groove.

[0009] The first groove is provided with a first screw hole, the second groove is provided with a second screw hole, and the crossbar is provided with a radially penetrating fixing bolt, which can cooperate with the first screw hole or the second groove.

[0010] The bottom surface of the seat cushion is provided with a positioning recess extending in the front-to-back direction, and positioning steps are provided on the left and right sides of the positioning recess; the crossbar is provided with positioning protrusions at intervals in the left-to-right direction, and the positioning protrusions can respectively abut against one side of the positioning steps.

[0011] The upper surface of the seat cushion is uniformly provided with anti-slip ridges and several hollow holes.

[0012] Armrests are installed on the left and right sides of the seat cushion, and a backrest is installed on the rear side of the seat cushion.

[0013] The beneficial effects of this utility model are:

[0014] 1. The X-shaped support structure itself possesses excellent mechanical stability and load-bearing capacity. By engaging the upper end (first end) of the support with pre-set support grooves of varying spacing (such as the first groove and the second groove) at the bottom of the seat cushion, the seat height is deterministically changed by altering the angle of the support using geometric relationships. Compared to traditional telescopic rod structures, the X-shaped support, as a single integral component, offers higher stability. When the crossbar at the first end engages with the first or second groove, the support and seat cushion form a stable structure. The crossbar is further secured in the selected groove using fixing bolts. Compared to the locking bolts used in traditional telescopic rod structures, the fixing bolts in this design do not bear excessive shear force from the telescopic rod, resulting in a more stable and reliable structure and reducing safety hazards.

[0015] 2. The adjustment operation is also relatively simple and intuitive. Height adjustment does not require tightening multiple bolts or finding alignment in multiple holes. The user only needs to lift the seat plate, move the upper end (first end) of the X-shaped support leg so that it falls into the support groove group corresponding to the target height (such as the first groove with L1 spacing or the second groove with L2 spacing), and then tighten the fixing bolts. Furthermore, the positioning protrusion on the crossbar and the positioning step under the seat plate can quickly align the fixing bolts with the screw holes. Attached Figure Description

[0022] To make the technical problems solved by the present utility model, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the present utility model will be further described below in conjunction with the attached drawings and through specific implementation manners. It can be understood that the specific embodiments described herein are only used to explain the present utility model and are not intended to limit the present utility model. Additionally, it should be noted that for the sake of description, only the parts related to the present utility model are shown in the attached drawings rather than all of them.

[0023] Refer to Figure 1 、 Figure 2 The present utility model provides an adjustable-height bathing chair, which includes a seat cushion plate 1 and a support component 2 disposed under the seat cushion plate 1. The support component 2 includes X-shaped feet 20. The feet 20 include two first ends 22 arranged front and back at the upper end and two second ends 23 arranged front and back at the lower end. An articulated point 21 is provided between the first end 22 and the second end 23. The first end 22 can rotate around the articulated point 21, causing the two first ends 22 to approach or move away from each other in the front-back direction;

[0024] The lower surface of the seat cushion plate 1 is provided with support recesses 10 that can be fixedly fitted with the first ends 22. At least two groups of support recesses 10 are provided. Each group of support recesses 10 includes two cooperating grooves arranged front and back. When the first ends 22 cooperate with different groups of support recesses 10, the vertical distance between the first ends 22 and the second ends 23 in the up-down direction can be adjusted.

[0025] Refer to Figure 2 As an embodiment, the support recesses 10 include a group of first grooves 100 arranged front and back and a group of second grooves 101 arranged front and back. The distance between the first grooves 100 is L1, and the distance between the second grooves 101 is L2, where L1 < L2. Specifically, when the first end 22 cooperates with the first grooves 100, the included angle of the X-shaped feet 20 in the up-down direction is smaller than the included angle when the first end 22 cooperates with the second grooves 101, that is, the height in the up-down direction changes.

[0026] Refer to Figure 3There are two support legs 20, which are arranged on the left and right sides under the seat pad 1. A crossbar 220 is connected between the first end 22 of the support legs 20 at the front and rear, respectively. The crossbar 220 can cooperate with the first groove 100 or the second groove 101.

[0027] Specifically, the X-shaped support leg 20 structure itself possesses excellent mechanical stability and load-bearing capacity. By engaging the first end 22 of the upper part of the support leg 20 with the first groove 100 and the second groove 101 with different spacings pre-set on the bottom of the seat cushion 1, the angle of the support leg 20 is changed using geometric relationships, thereby determining the seat height of the seat cushion 1. Compared to traditional telescopic rod structures, the X-shaped support leg, as a single integral component, has higher stability.

[0028] Reference Figure 3 The first groove 100 is provided with a first screw hole 111, the second groove 101 is provided with a second screw hole 110, and the crossbar 220 is provided with a radially penetrating fixing bolt 222, which can cooperate with the first screw hole 111 or the second groove 101.

[0029] Specifically, when the crossbar 220 at the first end 22 engages with the first groove 100 or the second groove 101, the support leg 20 and the seat plate 1 form a stable structure. The crossbar 220 is then further fixed in the selected groove by the fixing bolt 222. Compared to the locking bolts used in traditional telescopic rod structures, the fixing bolt 222 in this design does not bear excessive shear force from the telescopic rod, resulting in a more stable and reliable structure and reducing safety hazards. Furthermore, the fixing bolt 222 is located under the seat plate 1, in a relatively concealed position. Its corrosion risk is far lower than that of the numerous exposed bolt holes in traditional multi-hole adjustment methods, avoiding the risk of corrosion failure due to long-term exposure to the humid environment of the bathroom, further improving structural stability.

[0030] Reference Figure 3 , Figure 4 and Figure 5 The bottom surface of the seat cushion 1 is provided with a positioning recess 12 extending in the front-to-back direction, and positioning steps 120 are provided on the left and right sides of the positioning recess 12; the crossbar 220 is provided with positioning protrusions 221 at intervals in the left-to-right direction, and the positioning protrusions 221 can respectively abut against one side of the positioning step 120.

[0031] Specifically, compared to traditional telescopic rod structures, the height adjustment of this shower chair does not require tightening multiple bolts or finding alignment in multiple holes. The user only needs to lift the seat plate 1, move the first end 22 of the X-shaped support leg 20 so that it falls into the support groove group corresponding to the target height, such as the first groove 100 with an L1 spacing or the second groove 101 with an L2 spacing, and then tighten the fixing bolt 222. Furthermore, by using the positioning protrusion 221 on the crossbar 220 and the positioning step 120 under the seat plate 1, the fixing bolt 222 can be aligned with the screw hole under the seat plate 1 relatively quickly, making the adjustment operation simple and intuitive. In actual use, during the process of the crossbar 220 being inserted into the support recess 10, its fixing bolt 222 may not be aligned with the screw hole under the seat plate 1. At this time, it is necessary to move the seat plate 1 or the crossbar 220 left and right. After the two positioning protrusions 221 of the crossbar 220 abut against one side of the positioning step 120, it is necessary to press the crossbar 220 again to make it fully inserted into the support recess 10 to complete the positioning and engagement. Finally, tighten the fixing bolt 222.

[0032] Reference Figure 6 The upper surface of the seat cushion 1 is evenly provided with anti-slip raised textures 13 and several perforated holes 14. The anti-slip raised textures 13 effectively prevent the user from slipping, and the perforated holes 14 promote the rapid drainage of water accumulated on the seat.

[0033] Armrest tubes 3 are installed on both sides of the seat cushion 1, and a backrest 4 is installed on the rear side of the seat cushion 1. The armrests and backrest 4 provide additional support and comfort, making them especially suitable for users with limited mobility. The entire design fully considers the needs of use in the slippery environment of the bathroom. Preferably, the seat cushion 1 and backrest 4 are made of lightweight plastic, making the shower chair relatively lightweight, simple to mold, and low in cost.

[0034] In summary, this shower chair uses an X-shaped support leg 20 for geometric adjustment, combined with multiple preset support grooves 10 at the bottom of the seat cushion 1 for adjustment, which ensures its basic height adjustment function. More importantly, it significantly improves the stability and durability of the product. The overall structure is relatively simple and suitable for the use needs of bathroom scenarios.
