Description

  The present invention relates to a structure for attaching an attachment body having a metal frame to a cabinet, and more specifically to a structure for fastening a speaker unit having a metal frame to a cabinet of a television receiver.

A structure in which a speaker unit is fastened to a cabinet of a television receiver with screws is conventionally known (see Patent Document 1). FIG. 6 is a perspective view of a cabinet (1) and a speaker unit (2) of a conventional television receiver proposed by the applicant. The cabinet (1) has a large opening (10) in which a display can be fitted, and a wall piece (40) which is a substantially elliptical cylindrical body for receiving the speaker unit (2) is provided below the large opening (10). Yes. Hollow bosses (4) and (4) are erected on the periphery of the wall piece (40), and the speaker unit (2) is fixed to the bosses (4) and (4) with screws (6).
FIG. 7 is a perspective view of the speaker unit (2) viewed from the back. The speaker unit (2) is configured by providing a speaker (20) on a metal-made rectangular frame (3), and an arrow paper (21) is stretched on the back surface of the frame (3). When the speaker unit (2) is attached to the boss (4) (4), the arrow paper (21) closes the gap between the speaker unit (2) and the peripheral part of the wall piece (40), and leaks sound. It is a sealing body to prevent and has a so-called packing role. In the four corners of the frame (3), corresponding to the bosses (4) and (4), through holes (30) and (30) through which the screws (6) pass are formed.

FIG. 8 is a diagram showing a state in which the speaker unit (2) is attached to the bosses (4) and (4), and FIG. 6 is viewed from the A direction. The arrow paper (21) is in contact with the upper end of the peripheral edge of the wall piece (40), and in this state, a gap H1 is formed between the back surface of the frame (3) and the upper end of the boss (4). The outer periphery of the frame (3) is separated from the boss (4).
The frame (3) is fixed to the bosses (4) and (4) with four screws (6) and (6), but not all screws (6) and (6) can be fastened at the same time. Fastened from one screw (6) shown. After this, the other three screws (6) and (6) are attached in order. Screw the speaker unit (2) by the gap H1 with four screws (6) and (6). The arrow paper (21) is urged to the peripheral portion of the wall piece (40) by the fastening force of the screw (6). As a result, sound leakage and the like are prevented and good sound quality is obtained.

JP 2001-309277 A

Conventionally, as shown in FIG. 9, if one screw (6) corresponding to one corner of the frame (3) is fastened, the frame (3) is pushed down by the gap H1. (3) The other corner is raised. In this case, the attachment between the other through hole (30) and the boss (4) is displaced, and it is difficult to fix the next screw (6). As a result, the mounting workability of the speaker unit (2) in the manufacturing process is deteriorated. In this case, it is conceivable that the gap H1 is made as small as possible to reduce the amount by which the other corners of the frame (3) are lifted. However, the arrow paper (21) has a large thickness tolerance, and the gap H1 cannot be suppressed to a constant dimension.
An object of the present invention is to improve the workability of attaching a speaker unit provided with an arrowhead to a cabinet.

A structure in which a peripheral portion of a mounted body having a metal frame (3) is attached to a boss (4) on a cabinet (1) with a screw (6),
On the side of the boss (4), a projecting piece (5) made of a softer material than the frame (3) is provided, and the frame (3) faces downward while being screwed to the boss (4). The peripheral edge of the frame (3) bent in the direction bites into the projecting piece (5) and receives an upward reaction force by the projecting piece (5).
A wall piece (40) lower than the boss (4) is provided on the side of the boss (4), a sealing body is provided on the back surface of the frame (3), and the sealing body is a wall piece (40 A gap H1 is formed between the frame (3) and the upper end of the boss (4) in contact with the upper end of the boss.

A gap H1 is formed between the frame (3) and the upper end of the boss (4) in a state where the sealing body of the mounted body, specifically, the paper sheet (21) is in contact with the upper end of the wall piece (40). Is formed.
When fixing the frame (3) to the boss (4) with the screw (6), the frame (3) is pushed downward by the gap H1. At this time, the peripheral edge of the frame (3) bites into the projecting piece (5) . The frame (3) receives an upward reaction force by the projecting piece (5). Therefore, the frame (3) is restricted from floating. As a result, the workability of fixing the object to be attached, specifically, the screw (6) of the speaker unit (2) is improved, and the workability of attaching the speaker unit (2) can be improved.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a cabinet (1) and a speaker unit (2) of a television receiver. The cabinet (1) has a large opening (10) in which a display can be fitted, and a wall piece (40) which is a substantially elliptical cylindrical body for receiving the speaker unit (2) is provided below the large opening (10). Yes. Hollow bosses (4) and (4) are erected on the periphery of the wall piece (40), and the speaker unit (2) is fixed to the bosses (4) and (4) with screws (6). On the side of the wall piece (40), a protruding piece (5) is provided in contact with the wall piece (40). The cabinet (1), the wall piece (40), and the protruding piece (5) are made of synthetic resin.
The structure of the speaker unit (2) is the same as that of the prior art. The speaker unit (2) is configured by providing a speaker (20) on a metal-made rectangular frame (3). ) Is stretched. The arrow paper (21) is in close contact with the wall piece (40), so that sound leakage of the speaker unit (2) can be prevented and good sound quality can be obtained. At four corners of the frame (3), through holes (30) and (30) through which screws (6) pass are formed. Since the frame (3) is made of metal and the protruding piece (5) is made of synthetic resin, the frame (3) is harder than the protruding piece (5).

FIG. 2 is a front view showing a state in which the speaker unit (2) is to be attached to the boss (4), and FIG. 3 is an enlarged view of one corner of the frame (3). The peripheral edge of the frame (3) is bent downward and touches the upper end of the projecting piece (5).
When the frame (3) is fixed to the boss (4) with the screw (6), the gap H1 (see FIG. 8) is applied after the arrow paper (21) comes into contact with the upper end of the wall piece (40) as in the conventional case. Push the frame (3) downwards as much as possible. As shown in FIG. 4, first, one corner of the frame (3) is fixed with a screw (6), and the frame (3) is pushed downward. During fastening of the screw (6), the lower end of the peripheral edge of the frame (3) bites into the protruding piece (5). Since the frame (3) is harder than the projecting piece (5), the projecting piece (5) is deformed, and the frame (3) receives an upward reaction force due to the deformation of the projecting piece (5).

Since the frame (3) receives an upward reaction force from the projecting piece (5), the other corners of the frame (3) are restricted from floating. This prevents the frame (3) from floating when the screw (6) is fastened. As a result, the workability of fixing the screws (6) of the speaker unit (2) is improved, and the workability of mounting the speaker unit (2) can be improved.
When all four screws (6) and (6) are attached, the attachment of the speaker unit (2) to the cabinet (1) is completed as shown in FIG.

The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. In addition, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.
In this example, the speaker unit (2) is exemplified as the mounted body to be fastened with the screw (6). However, the speaker unit (2) can be used as long as it is fastened with a plurality of screws (6) and (6). Others may be used.
That is, the technical idea of the present invention can be applied to any configuration that prevents the other end portion of the attached body from being lifted when the one end portion of the attached body is fastened with the screw (6).
