Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a mounting mechanism for mounting a cabinet front frame onto a cabinet body, which is suitable for application to, for example, a cabinet front frame of a large television receiver or the like.

[Prior Art] The front frame of a cabinet is an exterior component and is easily collided with people, resulting in damage, scratches, stains, etc.

Therefore, it was necessary to replace and maintain the front frame of the cabinet. Conventionally, the following mechanisms have been proposed as attachment mechanisms for cabinet front frames.

FIGS. 14 and 15 show a first type of mounting mechanism, which is used, for example, in word processor keyboards and display glass filters.

In the figure, 1 is a resin cabinet front frame (hereinafter referred to as "front frame"), and 2 is a cabinet body (hereinafter referred to as "front frame").
(referred to as the "main body").

3 is a hook protruding from the lower end of the front frame 1 in a hook shape. 5 is a magnet attached to the upper end of the front frame 1.

Reference numeral 4 denotes a cylindrical guide provided at the lower end of the main body 2 at a portion of the front frame l corresponding to the hook 3, which receives the hook. A magnet 6 is provided at the upper end of the main body 2 at a position corresponding to the magnet 5 of the front frame 1, and is opened at the same time as the magnet 5 of the front frame 1.

In this mounting mechanism, the hook 3 is engaged with the guide 4 while the front frame 1 is tilted with respect to the main body 2.
The front frame 1 is rotated toward the main body 2 using the rotation fulcrum. At the same time as this rotation ends, the magnet 5 of the front frame 1 is attracted and fixed to the magnet 6 of the main body 2. Thereby, the front frame 1 is attached to the main body 2.

FIG. 16 shows a second type of mounting mechanism, which is used, for example, in the front frame of a speaker or the like.

In the figure, reference numeral 7 denotes elastic strikers made of synthetic resin that protrude at regular intervals in the longitudinal direction of the front frame 1, and the strikers 7 are shaped like a medium-thin bottle.

Reference numerals 8 denote latches provided at portions of the main body 2 corresponding to the strikers 7 of the front frame 1. The latch 8 has a substantially cylindrical shape, is made of elastic synthetic resin like the striker 7, and receives the striker 7.

In this mounting mechanism, the plurality of strikers 7 are engaged with the latches 8 almost simultaneously and mounted with the front frame 1 parallel to the main body 2 and the plurality of strikers and the latches 8 aligned.

[Invention tries to solve! ! ! [1] By the way, in the mounting mechanism according to the first type described above, the mounting strength can be increased by making the mounting of the magnets 5 and 6 sufficiently strong.

However, in this case, since it is locked only at both ends, uniform close contact cannot be obtained with a large front frame or a front frame 1 having a complex shape, such as an arc, due to flexure of the front frame 1.

Moreover, in the mounting mechanism according to the second type described above,
Although it is possible to improve the adhesion between the front frame 1 and the main body 2, the attachment strength is weak, and it is necessary to align the positions of multiple strikers 7 and latches 8 and attach them all at the same time. The surface is not smooth, and is not particularly suitable for large-sized front frames 1 or front frames 1 with complicated shapes.

Therefore, when using a cabinet front frame that is a separate part for a large television receiver, etc., the structure is often such that it cannot be easily attached or detached.For example, the front frame is attached to the cathode ray tube and the main body, respectively. , It takes a lot of knowledge to attach and detach the front frame, and it is not efficient.

Therefore, the present invention provides a front frame mounting mechanism that improves the adhesion between the front frame and the main body and increases the mounting strength without complicating the mounting/detaching operation.

[Means for Solving the Problems] In order to solve the above-mentioned problems, in the present invention, the cabinet front frame is positioned at one end of the cabinet front frame, and the cabinet front frame is rotated using the one end as a rotation fulcrum. a first stop portion for rotationally guiding the cabinet to the cabinet body; a second lock portion for fixing the cabinet front frame and the cabinet body at the other end; With an appropriate interval between the stop part of 1,
A third locking portion is provided for sequentially locking the cabinet front frame and the cabinet body during rotation of the cabinet front frame.

On the other hand, the cabinet body has fourth, fifth, and sixth locks for locking each of the locking portions to the cabinet body at portions corresponding to the first, second, and third locking portions. There will be a section.

[Function] In the above-described configuration, when the front frame 1 is tilted with respect to the main body 2, one end of each of the front frame 1 and the main body 2, that is,
The positions of the first locking part 3 and the fourth locking part 4 are determined.

Next, when the front frame 1 is rotated toward the main body 2 using one end of the front frame 1 as a rotation fulcrum P, the fourth locking part 4 guides the first stop part 3, and the first stop part 3.

In this case, since the rotation fulcrum P is positioned and the rotation is guided, the other end of the front frame 1 moves accurately toward the other end of the main body 2, and the third stop 7 and the sixth The locking portions 8 of the front frame 1 are sequentially and smoothly locked during rotation of the front frame 1.

When the third locking part 7 and the sixth locking part 8 are all locked, the front frame 1 and the main body 2 are in good contact with each other.

Further, when the rotation of the front frame 1 is completed, the second locking part 5 and the fifth locking part 6 are in an engaged state, and the front frame 1 is firmly fixed to the main body 2.

Further, when the front frame 1 is to be removed from the main body 2, it can be simply done by following the procedure reverse to the above.

That is, the second locking portion 5 on the other end side and the fifth stopper portion 6 are unlocked, and rotated about the rotation fulcrum P on the one end side. Along with this rotation, the second locking part 5 separates from the fifth locking part 6, and the locking between the third locking part 7 and the sixth locking part 8 is sequentially released. go.

Then, by releasing the lock between the first locking part 3 and the fourth locking part 4 on one end side and separating one end of the front frame 1 from the main body 2, the front frame 1 can be easily separated from the main body 2. Can be removed.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 13. In these FIGS. 1 to 13, parts corresponding to those in FIGS. 14 to 16 are designated by the same reference numerals.

This embodiment is an example of a mounting mechanism for a cabinet front frame in a large, box-shaped television receiver.

First, the structure of the front frame 1 will be explained. The first ward is the front frame 1
This shows the back side of the . The front frame 1 made of resin forms a rectangular frame body which is long in the horizontal direction. As shown in FIG. 2, the side surface of the front frame 1 has an arcuate front surface, and side walls are formed approximately perpendicularly to each edge of this surface.

As shown in FIG. 1, a plurality of hooks 3, three in this example, are provided at the upper end of the front frame 1 at predetermined intervals in the lateral direction. This hook 3 is provided over a wide range because it serves as a positioning reference when rotating. This hook 3 is
As shown in FIG. 2, the hook 3 has an L-shape, and the long piece of the hook 3 has a substantially rectangular locking hole for engaging with a guide 4, which will be described later, as shown in FIG. 3a is provided protrudingly. The position of one end of this locking hole 3a is such that it comes into pressure contact with a guide surface 4a of a guide 4, which will be described later, when the front frame 1 is attached.

Further, as shown in FIG. 1, a plurality of strikers 7, three in this example, are provided vertically at both ends of the front frame 1 at predetermined intervals.

This striker 7 is for assisting in the close contact between the front frame 1 and the main body 2, and as shown in FIGS. 2 and 3, it is made of elastic synthetic resin or the like and is shaped like a bottle with a medium narrow cross section. has been done.

Further, at the lower end of the front frame 1, as shown in FIG. 1, a plurality of strikers 7, three in this example, are provided at predetermined intervals in the lateral direction. This striker 7 is similar to the strikers 7 provided at both ends.

Further, a plurality of fixing pieces 5, in this example two on both sides, are attached to the lower end of the front frame 1 (see Fig. 1), and these fixing pieces 5 are attached as shown in Fig. 2. , stepped.

A screw hole 5a is bored in the protruding portion of this fixing piece.

Next, the structure of the main body 2 will be explained.

Figure 4 shows the front side of the main body 2. The main body 2 is made of resin and is molded into a substantially rectangular tube shape, and has a space in which a chassis (not shown) etc. can be stored. . As shown in FIG. 5, the upper edge of the main body 2 is provided with a protrusion 4b extending forward, so that the upper edge of the front frame 1 can come into contact with the corner of the protrusion 4b. This abutting position serves as a rotational fulcrum P, so that it is in a straight line in the lateral direction.

An opening 9 is provided in a portion of the front frame 1 described above that corresponds to the hook 3. This opening 9 is square, and a plate-shaped guide 4 is formed integrally with the main body 2 at the upper end of this opening 9. In this example, the reason why the guide 4 is formed into three plate shapes spaced apart at regular intervals is to ensure a constant width in a resin molded product having a limited plate thickness.

This guide 4 includes, as shown in FIGS. 4 and 7,
A curved guide surface 4a that comes into contact with one end of the locking hole 3a of the hook 3 described above is formed.

In addition, the above-mentioned front frame 1 is provided at both ends and the lower end of the main body 2.
A punch 8 is provided at a location corresponding to the striker 7. As shown in FIGS. 5 and 6, the latch 8 has a substantially rectangular parallelepiped shape having an insertion hole 8a into which the rattriker 7 is fitted, and is made of elastic synthetic resin or the like.

The insertion hole 8a has a depth of zero in order to maintain the locked state after the striker 7 is retracted.

A receiving portion 6 is provided at the lower end of the main body 2 at a portion corresponding to the fixing piece 5 of the front frame 1 described above. This receiving part 6 has a plate-shaped hole 6a bored in the front surface thereof at a corner of the lower edge of the main body 2 for engaging the protruding part of the fixing piece 5 of the front frame 1). (See Figure 5).

Further, a screw hole 6 for fixing the fixing piece 5 to the receiving part 6 is provided at a portion of the receiving part 6 corresponding to the screw hole 5a of the fixing piece 5.
(b) is perforated on the underside (see Section 5).

Next, the installation of the front frame 1 will be explained in the following procedure.

First, as shown in FIG. 8, the front frame 1 is tilted by aligning the upper edge of the front frame 1 with the corner of the protruding piece 4b of the main body 2,
Place the upper edge of the front frame 1 on the rotation fulcrum P4, and insert the front frame 1 into the opening 9 of the main body 2. When the guide 4 is rotated, the guide 4 is guided with one end of the locking hole 3a and the guide surface 4a of the guide 4 in contact with each other.

As a result, as shown in FIG. 9, the hook 3 and guide 4
and are engaged.

In this case, the rotation position of the front frame 1 is determined by being positioned at the rotation fulcrum P and guided by the guide 4, so that the lower end of the front frame 1 naturally moves toward the lower end of the main body 2.
and be moved accurately.

Therefore, during the rotation of the front frame 1, the strikers 7 of the front frame 1 retract and engage all the latches 8 of the main body 2 in a state exactly opposite to each other (see FIGS. 10 and 11).

That is, near the entrance of the insertion hole 8a of the latch 8,
The striker 7 is compressed from both sides of the latch 8 and sinks into the insertion hole 8a. As a result, the insertion hole 8 of the latch 8
The striker 7 is now locked in the interior a.

Note that since the latch 8 has a function of guiding the striker 7 to a certain extent, it can be engaged accurately even if there is a slight deviation.

Further, as the front frame 1 rotates, the protruding portion of the fixing piece 5 of the front frame 1 enters the hole 6a of the receiving portion 6 of the main body 2 (the 12th
(see Figure and Figure 13).

13, after inserting the screw 10 into the screw hole 6b of the receiving part 6 of the main body 2, the fixing piece 5 of the front frame 1
screw into the screw hole 5a.

Therefore, in this state, even if the front frame 1 is deformed due to bending, the front frame 1 and the main body 2 are in good contact with each other, and the mounting strength is strong.

Furthermore, the procedure for removing the front frame 1 from the main body 2 is performed in the reverse order to the above-mentioned installation procedure.

That is, after removing the screw 10, the front frame is rotated about the pivot point P in a direction away from the main body 2.

With this rotation, the fixing piece 5 separates from the receiving part 6, and the latch 8 and the striker 7 are sequentially disengaged from below.

Then, one end of the locking hole 3a of the hook 3 is disengaged while being guided by the guide surface 4a of the guide 4, and the hook 3 is removed from the opening 9.

Thereby, the front frame 1 can be easily removed from the main body 2.

Therefore, according to this example, even if the front frame 1 is large, the hook 3 is inserted into the opening 9, the front frame 1 is rotated about the rotation fulcrum P, and the striker 7 is The front frame 1 is attached to the main body 2 by smooth locking with the latch 8 and screw attachment between the fixing piece 5 and the receiving part 6, making it easy to attach and detach the front frame 1 from the main body 2. It can be carried out. In addition, uniform close contact between the front frame 1 and the main body 2 can be obtained by locking the striker 7 and the latch 8, and the front frame 1 and the main body 2 can be firmly attached by screwing the fixing piece 5 and the receiving part 6. Can be fixed.

In addition, the hook 3, guide 4, opening 9, striker 7, latch 8, fixing piece 5, and receiving part 6 in the above-mentioned embodiment
The shape, size, number, etc. of these are not limited to these.

For example, the hook 3 and the guide 4 may have any shape as long as they have one end that functions as a guide and a stop when rotating.

Further, since the striker 7 and the latch 8 are for assisting in the close contact between the front frame 1 and the main body 2, they are particularly effective when provided at a location with a complicated shape. Further, instead of the striker 7 and the latch 8, a magnet type, a Velcro (registered trademark), or a combination thereof, which can be easily attached and detached, may be used.

Furthermore, in the above embodiment, the fixing piece 5 and the receiving part 6 are fixed with screws, but the fixing means is not limited to this.

Further, in the above embodiment, the front frame 1 and the like are made of resin, but the material is not limited to this. However, if the deflection of the front frame 1 is taken into account, the present invention is effective when applied to resin-made ones.

Furthermore, the configurations of the locking parts provided on the front frame 1 and the main body 2 may be reversed. That is, the hook 3, the striker 7, and the fixing piece 5 are provided on the main body 2 side, and the guide 4, on the front frame 1 side, latch 8
, a receiving portion 6 may be provided.

Further, in the above embodiment, a large box-shaped television receiver has been described, but the apparatus is not limited to this as long as it has a mechanism for attaching the front frame 1 to the main body 2.

In particular, the present invention provides good adhesion and strong mounting strength, making it suitable for mounting on large or complex front frames.

[Effects of the Invention] As explained above, according to the present invention, it is possible to position the rotational support at one end of the front frame and the main body, and to establish the first stop portion and the fourth locking portion by rotation of the front frame. Accurate movement by rotational guidance of the front frame, locking between the third locking part and the sixth stopper during rotation, and locking between the second locking part and the second locking part. Fifth
Since the front frame is attached to the main body through a series of operations of fixing it to the locking portion, the front frame can be easily attached and detached, and has good adhesion and strong attachment.

Therefore, even in a device that is particularly large or has a complicated shape, and in which an inexpensive front frame made of resin or the like is attached to the main body, according to the present invention, the front frame and the main body can be easily attached, and good adhesion can be achieved.
