Embodiment Construction

[0027] Such as Figure 1A and Figure 1B As shown, the button body 10 includes a collar 12 , a shaft 14 and an insertion hole 16 for insertion of a fastener 18 . The button main body 10 is made of a material that allows the outer shape of the shaft 14 to expand out of position when the fixing piece 18 is inserted into the insertion hole 16, for example, synthetic resin is used in this embodiment.

[0028] The insertion hole 16 has a stepped form, and the inner diameter gradually becomes smaller toward the end surface facing the fixing piece 18 . In this embodiment, the insertion hole 16 includes a first hole 16A arranged in sequence on three steps as described above, a second hole 16B having an inner diameter smaller than that of the first hole 16A, and a second hole 16B having an inner diameter smaller than that of the second hole 16B. The inner diameter of the third hole 16C is small.

[0029] The protrusions 20 , 22 , 24 , 26 are integral with the shaft 14 . The protrusi...

Abstract

The present invention relates to a button comprising a button body and a fixture for fixing said button body to a support from the opposite side to the button body with the support therebetween, said button body having an insert hole defined by a wall, for the fixture to be inserted therein, and at least one protrusion for fixing on said support. According to the invention, there is provided a gap between said protrusion and said wall defining said insert hole.

Description

technical field [0001] The present invention relates to a button comprising a button body and a fixing member for fastening the button from the side opposite to the button body in a state where a support body is located between the button body and the fixing member. A main body is fixed to a supporting body, the button main body has an insertion hole defined by a wall for insertion of a fixing member, and at least one protrusion for being fixed on the supporting body. Background technique [0002] A button of the above-mentioned kind is known, for example, from EP 1 541 050 A1. With conventional buttons, since the outer diameter of the portion to be inserted of the fixing member is larger than the inner diameter of the insertion hole, when the fixing member is inserted into the insertion hole, the insertion hole is forced to expand, and thereby the The walls defining the aperture are forced to expand. However, with this conventional button, since the protrusion is position...
