Description

Technical Field

[0001] The utility model relates to a walker with a foldable dining board. Background Art

[0002] Prior art, such as the Chinese utility model patent document with publication number CN219783079U, discloses a walker. The walker frame is equipped with a seat, table, and storage compartment. The seat comprises a plate and a magnet. The front end of the plate is rotatably connected to the front rods of the left and right brackets. Magnets are located on both the top and bottom surfaces of the plate. The front rods of the left and right brackets are equipped with a first ferromagnetic metal block, and the two crossbars are equipped with a second ferromagnetic metal block. The table comprises a first rotating plate and a second rotating plate. One end of the first rotating plate is rotatably connected to the rear rod of the left bracket and the other end is equipped with a plug plate. One end of the second rotating plate is rotatably connected to the rear rod of the right bracket and the other end has a limit slot. Folding switches are provided between the first rotating plate and the left bracket, and between the second rotating plate and the right bracket. The storage compartment is detachably connected to the outer sides of the bottom of the two crossbars. This walker can be used by patients for resting, dining, or storing items.

[0003] Based on the above, in the prior art, a folding switch is used to achieve the rotation and folding of the first and second rotating plates. This folding switch includes a fixed cylinder, an insertion rod, and a spring catch. While the rotational coordination between the fixed cylinder and the insertion rod can achieve rotation and folding, the single connection support point results in poor stability, requiring further improvement.

[0008] Preferably, the connecting assembly includes a fixing member fixedly arranged on the side frame, and the fixing member is hinged to the connecting member;

[0009] An adjusting member is installed on the connecting member, and the adjusting member can be adjusted left and right relative to the connecting member;

[0010] The positioning column is fixedly arranged on the adjusting member, and the connecting rod is rotatably arranged on the adjusting member.

[0011] Preferably, the adjusting member has strip-shaped adjusting slots spaced apart in the upper and lower parts, and the connecting member has connecting holes spaced apart in the upper and lower parts;

[0012] A locking bolt is passed through the strip-shaped adjustment groove, and the locking bolt is threadedly connected to the connecting hole and abuts against the surface of the adjustment member.

[0013] Preferably, two connecting rods are provided and spaced apart in an upper and lower direction.

[0014] Compared with the prior art, the present invention features a connecting rod rotatably connected to the connecting assembly, the other end of which is rotatably connected to the dining board. A positioning post is provided on the connecting assembly, and the dining board is provided with a locking track groove and a position-limiting track groove that are interconnected. The positioning post is movably disposed within the locking track groove or the position-limiting track groove; when the dining board is in use, the positioning post slides into the locking track groove to form a lock. The present invention utilizes a connecting rod to constrain the rotational connection, and in conjunction with the positioning post and the locking track groove or the position-limiting track groove, it can effectively enhance the stability of the dining board connection, ensuring the normal use of the dining board, thereby improving stability during use.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See also Figure 1-Figure 5A walker with a foldable dining board includes side frames 10 spaced apart on the left and right sides, a connecting rod 100 is provided between the left and right side frames 10 to connect them to each other, a dining board 20 is provided between the left and right side frames 10, a connecting assembly 30 is provided on the side frames 10, a connecting rod 40 is rotatably connected to the connecting assembly 30, and the other end of the connecting rod 40 is rotatably connected to the dining board 20, a positioning column 50 is provided on the connecting assembly 30, and a locking track groove 220 and a limiting track groove 210 that are interconnected are provided on the dining board 20, and the positioning column 50 is movably provided in the locking track groove 220 or the limiting track groove 210; when the dining board 20 is in use, the positioning column 50 slides into the locking track groove 220 to form a lock.

[0022] The utility model adopts a connecting rod to constrain the rotation connection, and cooperates with the positioning column and the locking track groove or the limit track groove to effectively enhance the connection stability of the dining board to ensure the normal use of the dining board, thereby improving the stability during use.

[0023] See also Figure 2 The locking track groove 220 and the limiting track groove 210 are arranged in an L shape.

[0024] Furthermore, the rotation axis of the connection between the connecting rod and the dining plate 20 is located in front of the limiting track groove 210.

[0025] In the use state, the positioning post 50 is inserted into the locking track groove 220. In this state, the dining board 20 cannot be further flipped backward, thus locking the dining board 20. At this time, if the dining board 20 needs to be rotated from the use state to the folded state, it is necessary to flip it forward. During the flipping process, the positioning post 50 first returns from the locking track groove 220 to the front end of the limiting track groove 210, and then slides backward along the limiting track groove 210 until the dining board 20 is flipped to the Figure 4 and Figure 5 The state is the folded state.

[0026] See also Figure 2 , the connecting assembly 30 includes a fixing member 301 fixedly provided on the side frame 10, and the fixing member 301 is hinged to the connecting member 302;

[0027] An adjusting member 310 is mounted on the connecting member 302, and the adjusting member 310 can be adjusted left and right relative to the connecting member 302;

[0028] The positioning column 50 is fixedly disposed on the adjusting member 310 , and the connecting rod 40 is rotatably disposed on the adjusting member 310 .

[0029] The adjusting member 310 can be adjusted left and right relative to the connecting member 302 to realize the connection between the positioning column and the connecting rod and the dining board. At the same time, the left and right adjustment can meet the use of walkers of different widths, and the structure is universal.

[0030] See also Figure 2 The adjusting member 310 has strip-shaped adjusting grooves 311 spaced apart in the upper and lower parts, and the connecting member 302 has connecting holes 303 spaced apart in the upper and lower parts; a locking bolt is passed through the strip-shaped adjusting groove 311, and the locking bolt is threadedly connected to the connecting hole 303 and abuts against the surface of the adjusting member 310.

[0031] When adjusting the left and right positions, the left and right positions of the adjusting member 310 relative to the connecting member 302 can be adjusted by loosening the locking bolts. After the adjustment is completed, the locking bolts can be tightened.

[0032] See also Figure 4 There are two connecting rods 100 and they are spaced apart from each other.
