The through hole 12 is formed 11 through the mounting frame 10 between the fixed end and the limiting hole 11 of 12 the mounting frame 10. The two pivot holes 13 are formed through the mounting 13 frame 10 at a spaced interval, and the through hole 12 is disposed between the 14 two pivot holes 13. The pivot shaft 16 is connected to one of the two pivot holes 13 that is disposed between the through hole 12 and the fixed end of the mounting 16 frame 10. The at least one guiding slice 14 is aslant formed on and protrudes from 17 the side edge of the mounting frame 10 adjacent to the limiting hole 11 or the 18 through hole 12. Furthermore, the mounting frame 10 has two guiding slices 14, 19 and one of the two guiding slices 14 is disposed adjacent to the limiting hole 11, and the other one of the two guiding slices 14 is disposed adjacent to the through 21 hole 12.
22 The pivotal arm 20 is rotatably connected to the mounting frame 10, and 23 has a pivotal end, a pressing end, a flange 23, a positioning hole 21, a pivotal hole 24 22, and a pivotal rod 24. With reference to Fig. 6, the pivotal end of the pivotal 1 arm 20 is disposed away from the fixed end of the mounting frame 10, and is 2 pivotally connected to a seat 62 of the assistive device 60. The pressing end of the 3 pivotal arm 20 is opposite to the pivotal end of the pivotal arm 20 and selectively 4 abuts against the fixed end of the mounting frame 10 to limit the pivoting of the pivotal arm 20 relative to the mounting frame 10.
6 The flange 23 is formed on and protrudes from the pressing end of the 7 pivotal arm 20 and selectively abuts against the pivot shaft 16 of the mounting 8 frame 10. The positioning hole 21 is formed through the pivotal arm 20 and 9 selectively aligns with the through hole 12 of the mounting frame 10. The pivotal hole 22 is formed through the pivotal arm 20 adjacent to the positioning hole 21, 11 and aligns with the pivot hole 13 of the mounting frame 10 that is disposed 12 between the limiting hole 11 and the through hole 12. The pivotal rod 24 is 13 connected to the pivotal hole 22 and the corresponding pivot hole 13 to enable the 14 pivotal arm 20 to pivot relative to the mounting frame 10.
The operating element 30 is connected to the pivotal arm 20 and the 16 mounting frame 10 to limit a position of the pivotal arm 20 relative to the 17 mounting frame 10, and has a fixing ring base 31, an engaging bolt 32, and a pull 18 button 33. The fixing ring base 31 is securely connected to the pivotal arm 20 19 around the positioning hole 21. The engaging bolt 32 is movably mounted in the fixing ring base 31 and has an inserting end and a connecting end. The inserting 21 end of the engaging bolt 32 extends into the through hole 12 via the positioning 22 hole 21 to limit the position of the pivotal arm 20 relative to the mounting frame 23 10. The connecting end of the engaging bolt 32 extends out of the fixing ring base 24 31 and is opposite to the mounting frame 10.
1 The pull button 33 is connected to the connecting end of the engaging 2 bolt 32 to enable the engaging bolt 32 to move with the pull button 33 relative to 3 the through hole 12, the positioning hole 21, and the fixing ring base 31. In 4 addition, with reference to Fig. 4, when the inserting end of the engaging bolt 32 is separated from the through hole 12 by the pull button 33, the inserting end of 6 the engaging bolt 32 abuts against the at least one guiding slice 14 during the 7 rotation of the pivotal arm 20 relative to the mounting frame 10. Furthermore, 8 with reference to Fig. 5, when the positioning hole 21 aligns with the limiting 9 hole 11, the inserting end of the engaging bolt 32 is inserted into the limiting hole 11 via the positioning hole 21 to hold the pivotal arm 20 with the mounting frame 11 10.
12 Additionally, when the pull button 33 is released by a user, an elastic 13 element is mounted in the fixing ring base 31 and can provide a flexible force to 14 restore the engaging bolt 32 back to the original position. The elastic element and the return mechanism are conventional and the features and the structures of the 16 elastic element and the return mechanism are not described in detail.
17 The reinforcing rib 40 is connected to the mounting frame 10 and the 18 pivotal arm 20, and has a connecting end, a linking end, a curved segment 41, and 19 two communicating holes 42. The connecting end of the reinforcing rib 40 is connected to the fixed end of the mounting frame 10 to hold the pivotal arm 20 21 between the mounting frame 10 and the reinforcing rib 40. The linking end of the 22 reinforcing rib 40 is opposite to the connecting end of the reinforcing rib 40, and 23 is pivotally connected to the pivotal arm 20 and the mounting frame 10. The 24 curved segment 41 is formed on the reinforcing rib 40 between the connecting 1 end and the linking end of the reinforcing rib 40 and surrounds the fixing ring 2 base 31.
3 The two communicating holes 42 are formed through the reinforcing rib 4 40 respectively at the connecting end and the linking end of the reinforcing rib 40, and the communicating hole 42 that is disposed at the connecting end of the 6 reinforcing lib 40 aligns with the pivot hole 13 that is disposed adjacent to the 7 fixed end of the mounting frame 10. The pivot shaft 16 extends through the 8 communicating hole 42 that is disposed at the connecting end of the reinforcing 9 rib 40, and is connected to the corresponding pivot hole 13 to connect the reinforcing rib 40 with the mounting frame 10. The communicating hole 42 that 11 is disposed at the linking end of the reinforcing rib 40 aligns with the pivotal hole 12 22 of the pivotal arm 20 and the pivot hole 13 of the mounting frame 10 that is 13 disposed adjacent to the limiting hole 11. Then, the pivotal rod 24 is connected to 14 the reinforcing rib 40, the pivotal arm 20, and the mounting frame 10 via the corresponding communicating hole 42, the pivotal hole 22, and the 16 corresponding pivot hole 13.
17 With reference to Figs. 4 and 5, when the first embodiment of the 18 foldable frame construction for mobility aids is in use, the pull button 33 is pulled 19 to move away from the reinforcing rib 40, and the engaging bolt 32 is moved with the pull button 33 relative to the mounting frame 10 to separate from the through 21 hole 12. Then, the pivotal arm 20 can be pivoted relative to the mounting frame 22 10, and the pivotal arm 20 is pivoted relative to the mounting frame 10 with the 23 pivotal rod 24 as a fulcrum, so that the flange 23 is separated from the pivot shaft 24 16 and drives the engaging bolt 32 to move along and abut against the two 1 guiding slices 14 toward the limiting hole 11 of the mounting frame 10. The two 2 guiding slices 14 may provide a guiding effect to the engaging bolt 32.
3 When the engaging bolt 32 moves into the limiting hole 11 by the 4 guiding effect of the two guiding slices 14, the pivotal arm 20 cannot be pivoted relative to the mounting frame 10, and the first embodiment of the foldable frame 6 construction is set under a folded condition. Additionally, when a user wants to 7 unfold the first embodiment of the foldable frame construction, the pull button 33 8 is pulled to enable the inserting end of the engaging bolt 32 to separate from the 9 limiting hole 11, and this enables the pivotal arm 20 to pivot relative to the mounting frame 10 to move the engaging bolt 32 toward the through hole 12.
11 Then, the first embodiment of the foldable frame construction can be operated 12 under an unfolded condition conveniently.
13 With reference to Figs. 6 and 7, the first embodiment of the foldable 14 frame construction can be assembled on an assistive device 60 between a chair frame 61 and a seat 62. The mounting frame 10 is connected to the chair frame 61, 16 and the pivotal arm 20 is connected to the seat 62, and the seat 62 can be pivoted 17 relative to the chair frame 61 by the pivotal ann 20 pivoting relative to the 18 mounting frame 10. Then, the assistive device 60 can be folded by the first 19 embodiment of the foldable frame construction conveniently to save space for placing the assistive device 60. Furthermore, the assistive device 60 can move or 21 be transported in a small space under the folded condition, and this may provide 22 high practicality of the assistive device 60.
23 With reference to Figs. 8 and 9, a second embodiment of a foldable 24 frame construction for mobility aids in accordance with the present invention has 1 a mounting frame 10A, a pivotal arm 20A, an operating element 30A, and a 2 reinforcing rib 40A. The second embodiment of the foldable frame construction 3 is substantially the same as the first embodiment except for the following features.
4 The shapes and lengths of the second embodiment of the foldable frame construction are different from those of the first embodiment of the foldable 6 frame construction. With reference to Fig. 10, the mounting frame 10A is 7 connected to a foot frame 64A of an assistive device 60A, and the pivotal arm 8 20A is connected to a bottom frame 63A of the assistive device 60A.
9 Furthermore, the flange 23A is formed on and protrudes transversally from the pressing end of the pivotal arm 20A and selectively abuts against the pivotal rod 11 24A. Then, when the pivotal arm 20A is pivoted relative to the mounting frame 12 10A, the bottom frame 63A and the foot frame 64A of the assistive device 60A 13 can be pivoted with each other to enable the assistive device 60A to set under a 14 folded condition.
According to the above-mentioned features and structural relationships 16 of the foldable frame construction of the present invention, in use, a user only 17 needs to pull the pull button 33 of the operating element 30, 30A, and the 18 engaging bolt 32 can be separated from the through hole 12. Then, the pivotal 19 arm 20, 20A can be pivoted relative to the mounting frame 10, 10A, and the chair frame 61 and the seat 62 of the assistive device 60 or the bottom frame 63A and 21 the foot frame 64A of the assistive device 60A can be operated to fold 22 conveniently. After folding the mobility aids 60, 60A, the engaging bolt 32 is 23 moved into the limiting hole 11, and the pivotal arm 20, 20A cannot pivot relative 24 to the mounting frame 10, 10A. Therefore, the mobility aids 60, 60A can be 1 operated conveniently under the folded condition by the foldable frame 2 construction, and this also can reduce the space for placing the mobility aids 60, 60A, and can facilitate moving or transporting the mobility aids 60, 60A in a 4 small space to improve the practicality of the mobility aids 60, 60A.
Even though numerous characteristics and advantages of the present 6 invention have been set forth in the foregoing description, together with details of 7 the structure and features of the utility model, the disclosure is illustrative only.
8 Changes may be made in the details, especially in matters of shape, size, and 9 arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended 11 claims are expressed.
