<Comparison study example>
FIG. 9 is a perspective view of the back side of the back side member constituting the conventional call button device. FIG. 10 is a perspective view showing positioning of the back side member on the right frame part in the conventional example. FIG. 11 is a perspective view illustrating that the adhesive protrudes from between the frame member and the back side member in the conventional example.

  As shown in FIGS. 9 to 11, the call button device of the conventional example includes a call button (not shown) exposed from the openings 117 </ b> U and 117 </ b> L of the right frame portion 116 </ b> L constituting the frame member around the door, and the right frame. A back side member 128 fixed to the back side of the portion 116R with an adhesive, and a holding member attached to the back side of the back side member 128 to hold the call buttons so as to be able to move forward and backward in the back side direction (front-rear direction). (Not shown).

  The back-side member 128 has a flat plate shape made of iron plate, and the back-side member 128 is formed with back-side openings 126U and 126L that are superposed on the openings 117U and 117L, respectively. The dimensions of the openings 117U and 117L are slightly larger (for example, about 0.5 mm larger) than the outer shape of the call button, and the dimensions of the back side openings 126U and 126L are further slightly larger (for example, about 1 mm larger). Has been processed. A total of four bolts 129P for fixing the holding member are erected on the back side of the back side member 128, and a total of four bolts 129Q for fixing a box (not shown) for protecting the holding member are also erected. ing.

  When installing the call button device of the conventional example on the elevator hall, the operator places the right side frame portion 116R on the workbench, and then holds the back side member 128 in one hand and attaches the adhesive surface 128S (the back surface of the front side of the right side frame portion 116R). Adhesive is applied over the entire surface.

  Then, the back side member 128 is positioned and placed on the right side frame portion 116R. At that time, the back side openings 126U and 126L are overlapped with the openings 117U and 117L, that is, the adhesive escape space S is formed with a uniform width W around the openings 117U and 117L. The member 128 is placed in alignment with the right frame portion 116R. Further, a weight 158 is appropriately placed on the back side member in order to fill the adhesive uniformly between the right side frame portion 116R and the back side member 128. After the adhesive is solidified, the weight 158 is removed, and the adhesive protruding to the outer peripheral side of the back side member 128 and the adhesive protruding to the opening edge 117E of the openings 117U and 117L are removed with a tool or the like. By confirming the protrusion of the adhesive, confirmation that the adhesive can be filled evenly over the entire adhesive surface of the back side member 128 can be obtained.

  In such a conventional example, the adhesive K protruding from between the right frame portion 116R and the back side member 128 is covered to the opening edge 117E of the right frame portion 116R. Therefore, in order to prevent the calling button from coming into contact with the solidified adhesive K that has protruded, the protruding adhesive K needs to be sufficiently removed with a tool or the like. In particular, at the four corners of the opening 117E, the amount of protrusion of the adhesive K tends to increase and the removal work is complicated.

  In addition, due to uneven load due to the weight 158, the back side member 128 is displaced from the position where the adhesive is solidified during the solidification of the adhesive. For this reason, it takes time in the step of bonding the back side member 128 to the right side frame portion 116R.

  On the other hand, in the first embodiment, the protruding adhesive is accommodated in the back side sub-opening 25 even if a force is applied to the adhesive when the back side member 28 is bonded to the right frame portion 16R. Therefore, the adhesive hardly covers the openings 17U and 17L of the right frame portion 16R. Therefore, in addition to greatly shortening the time taken to remove the adhesive, it is possible to significantly reduce the possibility that the removal of the adhesive is insufficient and the call buttons 22U and 22L seize and cause malfunction. . In 2nd-5th embodiment, in addition to this effect, there also exists an effect which reduces a deformation | transformation of a back side member.

  Although some embodiments have been described above, these embodiments are presented as examples, and the scope of the invention is not intended to be limited to them. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof as well as included in the scope and gist of the invention.
