Description

  The present invention relates to an escutcheon, and more particularly to an attachment structure thereof.

  An example of a structure for attaching a conventional escutcheon (decorative frame) to an apparatus body will be described with reference to FIGS. A resin-made sub-panel 2 is fixed to the front surface of the casing 1 of the apparatus main body shown in FIG. .. Are formed in the upper and lower surfaces of the sub-panel 2. The escutcheon 4 made of resin is formed in a rectangular shape, provided with respective arm portions 5, 5... Projecting from both sides facing the upper and lower sides toward the device main body, and facing each other from the tip portions of the arm portions 5, 5. As shown, the claws 6, 6.

  The claws 6, 6... Fit into the recesses 3, 3,... And the escutcheon 4 is attached to the sub-panel 2. The details of the attachment state will be described with reference to FIG. The concave portion 3 of the sub-panel 2 is a bottomed concave portion 3a, and the claws 6, 6... Formed at the distal ends of the arm portions 5, 5. Is sandwiched.

  At this time, the arm portions 5 and 5 are in an elastically deformed state, and the tips of the claws 6, 6. In this manner, the escutcheon 4 is easily removed by preventing the claws 6, 6... And the bottomed recesses 3a, 3a.

  However, in recent years, there has been a tendency to increase the size of a movable monitor disposed on the front surface of an electronic device, and the sub-panel has become thinner, making it difficult to form a bottomed recess. Even if the bottomed recess can be formed, if the tip of the escutcheon claw is brought into pressure contact with the bottom of the bottomed recess, there is a problem that the strength of the sub-panel is insufficient and the sub-panel is bent.

  Therefore, as shown in FIG. 5B, the sub-panel 2 is provided with a through hole 3b so that an escutcheon claw 6 enters the through hole 3b. Thus, when the escutcheon claw 6 and the through hole 3b of the sub-panel 2 are engaged, the fitting becomes very strong, and once attached, there is a problem that it is difficult to remove even using a removal jig. there were.

In the assembly structure of the housing proposed in Japanese Utility Model Publication No. 62-62481, the claws provided on one side of the escutcheon are engaged with the through holes provided in the lower case, and the other side of the escutcheon is screwed. It is fastened to the lower case. Such an escutcheon mounting structure has a problem that it is troublesome to attach and remove the escutcheon because it is fastened with screws.
Japanese Utility Model Laid-Open Publication No. 62-62481, specification, page 2, line 17 to page 3, line 6; specification, page 5, line 11 to line 14, and FIGS.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an escutcheon attachment structure that can be easily attached and detached even when the attachment portion on the main body side such as a sub-panel is thin. is there.

  The attachment structure of the escutcheon of this invention is such that the claws protruding so as to face each other from the front end portions of the respective arm portions protruding from the opposite sides of the rectangular escutcheon into the device main body are inserted into the recesses of the device main body. In the escutcheon mounting structure for attaching the escutcheon to the front surface of the device main body, the concave portion is a through hole, a chamfered portion is provided at a corner sandwiched between the arm portion and the claw, and the chamfered portion is formed at the edge of the through hole of the device main body. It is configured to be pressed by the elasticity of the arm.

  In the escutcheon mounting structure, the through hole of the device main body is provided in a sub-panel fixed to the front surface of the housing.

  Moreover, in the attachment structure of each said escutcheon, the said chamfer part is formed in the plane.

  In the escutcheon mounting structure, the chamfered portion is formed in a curved surface that is convex with respect to the outside.

  In the escutcheon mounting structure, the chamfered portion is formed in a concave curved surface with respect to the outside.

  Moreover, in the attachment structure of each said escutcheon, the inclined surface inclined in the protrusion direction of an arm part and the protrusion direction of a nail | claw is formed over the front-end | tip of a nail | claw from the nail | claw side end of the said chamfering part.

  According to the escutcheon attachment structure of the present invention, the escutcheon can be easily attached and detached even when the attachment part on the main body side such as the sub-panel is thin.

  The best mode for carrying out the present invention will be described below with reference to examples.

  1A is a partial cross-sectional view showing an escutcheon mounting structure according to Embodiment 1 of the present invention, and FIG. 1B is a partially enlarged view of FIG.

  In this example, a flat chamfered portion 7a is provided at a corner between the claw 7 protruding from the tip of the arm portion 5 of the escutcheon and the arm portion 5, and the plane extending from the end of the chamfered portion 7a to the tip of the claw 7 is The arm portion 5 is inclined at an angle θ with respect to a vertical plane in the extending direction. Then, the chamfered portion 7 a is pressed against the edge of the through hole 3 b of the sub panel 2. Other configurations are the same as those of the conventional one shown in FIGS. 4 and 5B, and detailed description thereof is omitted.

  In this example, the escutcheon is attached so that the sub-panel 2 is sandwiched between the claws 7 and 7 protruding from the tips of the escutcheon arm portions 5 and 5. 2 is not pressed into the through hole 3b until the base of the claw 7, so that the arms 5 and 5 are open.

  Therefore, the fitting force necessary for attaching the escutcheon is obtained, and when removing the escutcheon, the escutcheon can be easily detached from the apparatus main body by pulling the escutcheon to the outside without causing the claw 7 to be caught in the through hole 3b. And since the inclined plane is provided from the end of the chamfered portion 7a to the tip of the claw 7, the operation when removing is smooth.

  FIG. 2 is a partial side view of a claw used in an escutcheon mounting structure according to Embodiment 2 of the present invention. In this example, a claw 8 is provided so as to protrude from the tip of the arm portion 5 of the escutcheon, and a chamfered portion 8a provided at a corner sandwiched between the claw 8 and the arm portion 5 is pressed against the edge of the through hole of the sub panel. The chamfered portion 8a is formed in a curved surface that is convex with respect to the outside, and the inclined surface 8b is inclined in the same manner as in the first embodiment. Other configurations are the same as those of the first embodiment, and detailed description thereof is omitted. In this example, the angle between the chamfered portion 8a and the inclined surface 8b is reduced, and a click feeling can be obtained when removing the escutcheon.

  FIG. 3 is a partial side view of a claw used in the escutcheon mounting structure according to Embodiment 3 of the present invention. In this example, a claw 9 is provided so as to protrude from the tip of the arm portion 5 of the escutcheon, and a chamfered portion 9a provided at a corner sandwiched between the claw 9 and the arm portion 5 is pressed against the edge of the through hole of the sub panel. The chamfered portion 9a is formed into a concave curved surface with respect to the outside, and the inclined surface 9b is inclined in the same manner as in the first embodiment. Other configurations are the same as those of the first embodiment, and detailed description thereof is omitted. In this example, the chamfered portion 9a and the inclined surface 9b are smoothly connected, and the movement when removing the escutcheon is smooth.

  The embodiment is configured as described above, but the invention is not limited to this. For example, the present invention can be applied to the case where the escutcheon is not directly attached to the sub-panel but is directly attached to the housing.

It is a partial side view of the nail | claw used for the attachment structure of the escutcheon which is Example 2 of this invention. It is a partial side view of the nail | claw used for the attachment structure of the escutcheon which is Example 3 of this invention. It is a disassembled perspective view which shows the example of the attachment structure of the conventional escutcheon.
