溶接すると云う手間のかゝるものである。 For example, in the case of the wheelchair frame 10 shown in FIGS. 1 and 2, the rear frame 1 and both side frames 3 on which the armrests 2 are mounted are arranged, and the rear frame 1 and both side frames 3 are arranged in the middle. Seat frame 4A to be connected, lower frame 4B to connect rear frame 1 and both side frames 3 at the lower part, X between both side frames 3 and lower frame 4
The rear frame 1 has a bearing 7 for the rear wheel 6, a caster 8 is rotatably attached to the lower end of the both side frames 3, and the front A footrest 9 is provided in the section. In the machine frame 10, the conventional footrest 9 extends the pivot plate 9B from the tip of the main rod 9A, as shown in FIGS. 3 to 5, and connects the pivot plate 9B to the support rod 9C.
It has a structure in which it is rotatably supported on a pivot shaft 9E in a fork 9D at the tip of the support rod 9C, and a stand 9F is passed between the support rods 9C. In order to lock it, a locking stand 9G is formed at the bottom of the fork 9D, and the lower edge of the pivot plate 9B is brought into contact with the locking stand 9G. In the above configuration, the angle of the base 9F, that is, the main rod 9A of the support rod 9C
In order to adjust the angle with respect to the lock, a rod-shaped or plate-like stopper 9H is welded onto the locking base 9G, as shown in FIG. This method uses the 9H
It takes a lot of time and effort to adjust the thickness as desired and then weld it onto the locking base 9G.

るものである。 The purpose of the present invention is to improve the above-mentioned drawbacks and make it possible to easily adjust the angle of the footrest according to the body shape of the user. In a joint mechanism consisting of another rod, a pivot plate is attached to the tip of the other rod, and the pivot plate is rotatably supported within the fork, so that the other rod is connected to the fork. The main feature is that the other rod body is locked by the end edge of the pivot plate coming into contact with the back wall surface of the fork.

から実線位置まで角度を変化させる。 The present invention will be described with reference to an embodiment shown in FIG.
It is inserted into a fork 19D formed at the tip of C, and is rotatably supported by a pivot 19E. A platform 19F is placed between the support rods 19C.
A two-stage slope 191B, 1 is provided on the edge of the pivot plate 19B.
92B is formed, and the lower end of the slope 192B comes into contact with the back wall surface 19G of the fork 19D. In this way, the base portion 19F, that is, the support rod 19C is locked at a certain angle with respect to the main rod 19A. When the angle is adjusted by the user, the pivot 19E is removed and the main rod 19 is adjusted.
A and the support rod 19C are separated, and the slope 192B of the pivot plate 19B is polished with a file, a grinder, or the like.
Thus, the angle of the support rod 19 changes from the dotted line position to the solid line position as shown in FIG.

上記実施例以外、例えば枢着板１９Ｂの端縁は

In short, any shape may be used as long as it does not prevent rotation of the pivot plate 19B. Furthermore, two forks are formed on the main rod 19A side,
A pivot plate may be formed on the support rod 19C side.

を調節することが出来る。 As described above, the present invention is a joint mechanism consisting of two rods attached to the tip of the rod and another rod pivotally attached within the two rods, and a pivot plate is attached to the tip of the other rod, and the pivot plate is attached to the tip of the rod. The other rod is rotatably supported within the fork, so that the other rod is pivoted within the fork, and the edge of the pivot plate comes into contact with the back wall of the fork, so that the other rod is pivoted within the fork. Since they are locked, the mounting angle between the rods can be adjusted very easily depending on the body shape of the user by polishing the edges of the pivot plate.
