Problems solved by technology

Not only that, but it is also difficult to apply to a structure in which rubber parts are arranged on flat parts such as substrates and the end faces of plate parts, etc. Therefore, when arranging in such a place, positioning of the rubber parts is difficult
Moreover, since the small protrusions are formed in the fitting holes, much space is wasted

Embodiment Construction

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0021] 1( a ) is a plan view showing a state in which a plurality of rubber members to which a positioning structure according to an embodiment of the present invention is applied is arranged on a substrate, and FIG. 1( b ) is a cross-sectional view along line A-A of FIG. 1( a ).

[0022] Hereinafter, when distinguishing and describing two of the plurality of rubber members R, especially two adjacent ones, they will be referred to as rubber members RA and RB. Since each rubber member R has the same structure, in the description, when each rubber member R is not particularly distinguished, it is only indicated as a rubber member R.

[0023] In FIG. 1( a ), an example in which a plurality of long rubber members R are continuously arranged in the longitudinal direction thereof is shown. These rubber members R are arranged, for example, in keyboard instruments. The rubber...

Abstract

A positioning structure for rubber parts is provided to simply position the rubber parts with high space efficiency. The adjacent rubber members (R) are continuously arranged along the surface direction of the base portion (11) (the direction parallel to the upper surface (11a)). At the position of the protruding portion (23) protrudingly arranged on the base plate (20), the arrangement direction The end portions in the (continuous arrangement direction) are arranged to overlap each other in the thickness direction of the base portion. The end portions in the continuous arrangement direction of the rubber members are overlapping portions. Engagement holes (15-1, 15-2) are formed in the overlapping portion (14-1) and the overlapping portion (14-2) respectively. On the overlapping portion (24) of the base plate, the rubber members are arranged such that the protrusions are inserted into the engagement holes and stacked in order of the overlapping portions (14-2, 14-1). By fitting the protrusion into the engagement hole, adjacent rubber members are relatively positioned in the direction in which the rubber members are continuously arranged.

Description

technical field [0001] The present invention relates to a rubber member positioning structure in which a plurality of rubber members having a base portion and made of an elastic material are continuously arranged. Background technique [0002] Conventionally, in order to install a plurality of dome-shaped switches, etc., it was necessary to arrange a plurality of elastic rubber members provided with a plurality of dome portions on an electronic device. For example, in the following Patent Document 1, in the keyboard device, three rubber members (switch members) each having a plurality of switches are arranged in the key array direction. [0003] In this way, when a plurality of rubber members are continuously arranged on a substrate or the like, some measures have been taken to position each rubber member. For example, in Patent Document 2 below, a structure in which a rubber member is supported by a holder is adopted. The positioning of the rubber member with respect to t...
