Description

[Detailed description of the invention] (a) Industrial application field For example, it can be used as an opening/closing structure for a door that closes control knobs arranged on the front of a television receiver.

(b) Prior Art FIG. 1 shows a schematic perspective view of a television receiver with a conventional door opening/closing structure, and FIG. 2 is a perspective view showing the structure of its main parts. A recess 3 is provided on the front surface of a cabinet 2, which is the outer shell of the television receiver main body 1, and various control knobs 4 are disposed within the recess 3. Further, an engagement hole 5 is formed in the bottom 3a of the recess 3, and a shaft rod 6 is provided in the side surface 3b. Reference numeral 7 denotes a door that closes the recess 3, and the door 7 is pivotally supported by inserting the shaft rod 6 into a hole 8 provided on its side surface. Further, an elastic engagement piece 9 is provided at the upper center of the back surface of the door 7, and when the door 7 is closed, the engagement piece 9
However, by engaging with the engagement hole 5, the closed state of the door 7 is maintained.

(c) Purpose In the door opening/closing structure as described above, the door is held in the closed state by engaging an engaging piece provided at the upper center of the door with an engaging hole in the cabinet recess.
The door could not be closed when the back surfaces of both ends of the door were in close contact with the bottom surface of the recess, creating a gap in that area.

The object of the present invention is to provide a door opening/closing structure that eliminates such drawbacks.

(d) Configuration A concave-convex portion is formed on the side surface of the coupling means of the door that is pivotally supported on the shaft provided on the device body, and this concave-convex portion is attached to a rib provided near the shaft on the device body side of the door. It was made to contact selectively depending on whether it is opened or closed.

(E) Embodiment An embodiment of the present invention will be described with reference to FIGS. 3 to 8.

As shown in the exploded perspective view of main parts in Figure 3, the cabinet (outer shell) of a device such as a television receiver, etc.
A recess 11 is provided on the front surface of the recess 10, and various control knobs and the like shown in the conventional example are provided on the bottom surface 11a of the recess 11, although not shown. Furthermore, recesses 12 and 1 are provided at both corners of the recess 11.
2 is formed, and each recess 12, 12 is provided with a shaft rod 13, 13, respectively. Further, ribs 14, 14 each having a semicircular cross section are provided on the side surfaces 11b, 11b of the recess 11 in a direction perpendicular to the axial direction of the shaft rods 13, 13, respectively.

On the other hand, on both ends of the back surface of the door 15 that closes the recess 11, a coupling means 16 is provided which grips the shaft rods 13, 13 and by which the shaft rod 13 is pivotally supported. The coupling means 16 is made of an elastic synthetic resin material and is integrally molded with the door 15.
5, and a pair of gripping pieces 16b, 16b extending in a bifurcated shape from the base 16a, and when the coupling means 16 is coupled to the shaft rod 13 as shown in detail in FIG. Said rib 14
The side surface of the coupling means 16 facing the is formed to have an uneven portion, for example, by providing a tab 16c on the gripping pieces 16b, 16b. The door 15 has gripping pieces 16b, 16b of the coupling means 16.
It is attached by press-fitting into the shaft rod 13 from between the holes.

FIG. 5 shows a case where the door 15 attached to the recess 11 is in an open state, and at this time,
As shown in FIG. 6, the convex portion on the side of one gripping piece 16b, that is, the dowel 16c of the gripping piece 16b comes into contact with the rib 14, and the connecting means 16 connects the shaft rod 13.
It is urged inward in the same direction (in the direction of arrow A) and is elastically deformed. When the door 15 is closed as shown in FIG. 7, the rib 14 is moved between the pair of gripping pieces 16 by the elastic restoring force of the coupling means 16 as shown in FIG.
The door 15 is stably held in the closed state by contacting the side portions 16d, 16d of both the gripping pieces 16b, 16b so as to face the gap 16e between the gripping pieces 16b, 16b.

(F) Effect: An uneven portion is formed on the side surface of the coupling means of the door that is pivotally supported by the shaft rods provided at both corners of the recessed portion of the device main body, and the uneven portion is located near the shaft rod on the device main body side. Since the provided ribs are selectively brought into contact with the opening/closing of the door, it is possible to improve the adhesion between the door and the concave portion of the main body of the device when the door is held closed with a simple structure. Further, when the door is closed, there is no visible means for maintaining the closed state, so it is excellent in terms of design.
