It is.

[Summary of the idea]

本考案は、ゴム等の弾性部材が圧縮されると復

たとき、ころがり軸受が弾性部材に突き当たるよ
うにして用紙受台ロツクされるように工夫したも
のである。 This invention focuses on the fact that when an elastic member such as rubber is compressed, it generates a restoring force, and that the elastic member also functions as a damper. The paper holder is compressed, and when the pushing of the paper holder is completed, the rolling bearing abuts against the elastic member to lock the paper holder.

８に加わる衝撃は吸収される。 Fig. 1 is a longitudinal sectional view showing the sliding method of the paper holder, Fig. 2 is a longitudinal sectional view showing the locking mechanism of the paper holder according to the present invention, and Fig. 3 shows the recessed portion that enables the paper holder to be locked. FIG. 2 is a perspective view showing an elastic member such as rubber. The paper holder 1 has a U-shaped rail a.
3. It is composed of a plate 2 to which the rail b10 is attached by welding or the like, and a protrusion member 5 to which the arm 4 is welded, and the protrusion member 5 is screwed to the plate 2. A rolling bearing 6 that allows the rails a3 and b10 to slide is fixed to a holder 7 screwed to the support base 8, or directly fixed to the support base 8. With the above configuration, the paper holder 1 can be pulled out together with the folded paper 9. At the top of the paper holder 1, an elastic member 12 made of rubber or the like (preferably urethane rubber with wear resistance) is provided with a recess 13 so that the rolling bearing 6 can fit into it. It is then fixed to the plate 2. With the above configuration, when an attempt is made to pull out the paper holder 1 by holding the handle 11, the elastic member 12 is compressed and cannot be pulled out unless pulled out with a strong force. The amount by which the rolling bearing 6 compresses the elastic member 12 is determined so that the paper holder 1 does not slide naturally when the paper 9 is folded.
In addition, the drawing force is ergonomically determined so as not to cause discomfort to the operator. When pushing in the pulled out paper holder 1, even if it is pushed in roughly, when the rolling bearing 6 begins to compress the elastic member 12, the pushing force is relaxed and the rolling bearing 6 fits into the recess 13 of the elastic member 12. At this time, the elastic member 12 acts as a damper, and the impact applied to the support base 8 is absorbed.

る。 Similar effects can be obtained if the material that fits into the recess provided in the elastic member is not only a rolling bearing but also a rod-shaped material. Of course, it is also possible to install the rolling bearing and the rail in reverse.

[Effect of idea]

る。 According to the present invention, since the paper holder is provided with an elastic member such as rubber having a recess into which the rolling bearing fits, the rolling bearing fits into the recess of the elastic member and the paper holder is locked. In addition, it can also function as a damper to reduce the impact when the paper holder is pushed in, and it is possible to provide an inexpensive locking mechanism for the paper holder with a small number of parts.
