Description

[Detailed Description of the Invention] The present invention relates to an audio rack having a shelf plate that can be detachably engaged with a rack main body having at least an open front side, and in particular, the above-mentioned shelf plate can be attached or detached without making it difficult to attach or detach the shelf plate. The purpose is to prevent sagging under load and to obtain sufficient strength.

Generally, audio racks are used to assemble various audio devices such as tuners and amplifiers to configure a stereo system.

By the way, the audio equipment constituting the stereo system is selected according to the user's preference, and the arrangement of the various selected equipment in the audio rack is configured so that the arrangement can be changed as desired by the user. It is common that

However, in audio racks, the requirements cannot be met simply by allowing the shelf boards to be freely attached and detached.

The shelf board must reliably support heavy audio equipment, and must not generate unnecessary vibrations or howling when the audio equipment is driven.

In conventional audio racks, a large number of locking protrusions are provided on the inner surfaces of the opposing side plates of the main body of the rack, and one of these protrusions is selected at a desired position, and the shelf board is attached to that protrusion. It is simply placed so that it can be inserted.

Therefore, if the shelf board is long enough and the audio equipment placed on the shelf board is heavy, the shelf board will be unable to withstand the load and will bend.

Furthermore, if an abnormal load is applied, such as in the case of an earthquake, the shelf board will not be able to sufficiently support the load.

In order to obtain strength against the above-mentioned deflection and load, it has been proposed that a partition plate is disposed in the center of the shelf board so as to be perpendicular to the shelf board.

However, with this type of product, even though it can provide strength against deflection, etc., the partition plates etc. are fixed to the side panels, which not only makes it impossible to attach and detach the shelves, but also makes it difficult to do so. Even if it were possible, it would be extremely difficult.

Furthermore, depending on the selection of the partition plates, howling may occur, making selection and mounting of the partition plates difficult, and making the audio rack itself expensive.

Therefore, the present invention solves the various problems that the conventional ones had as mentioned above, and makes it possible to obtain sufficient strength of the shelf board without making it difficult to attach or detach the shelf board, and to make it suitable for audio racks. The aim is to provide products that fully satisfy the requirements.

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.

FIG. 1 is a perspective view showing an example of an audio rack according to the present invention, and this audio rack is composed of a plurality of shelf boards 2 that can be detachably engaged with a rack main body 1.

The rack main body 1 is formed into a frame shape and is composed of a top plate 3 and a bottom plate 4 facing each other, and left and right side plates 5 and 6 facing each other.

Then, the opposing inner surfaces 5a of the window/right side panels 5 and 6
, 6a are locking pins 9 that are locking portions that respectively support the left and right sides 7 and 8 of the shelf board 2 when the shelf board 2 is attached.
, 10 are arranged.

These locking pins 9 and 10 are arranged in parallel in the horizontal direction of the rack body 1, and support one side of the shelf board 2 with these two pins forming a pair.

Then, a first
When the shelf board 2 is installed, the engaging pins 9 relatively engage with the engaging recesses 11 formed in the side parts 7 and 8 of the shelf board 2, and perform a positioning function and a displacement prevention function of the shelf board 2. There is.

Therefore, there is a gap in the height direction between the first engagement pin 9 that engages with the engagement recess 11 of the shelf board 2 and the second engagement pin 10 that simply contacts the back surface of the shelf board 2. A gap is provided between the shelves so that the shelf board 2 is always supported horizontally.

As mentioned above, the pair of engagement pins 9 and 10 that support the left and right sides 7 and 8 of the shelf board 2 are connected to the left and right sides 5 and 8 of the rack body 1, respectively.
6 A plurality of pairs of shelf boards 2 are arranged with appropriate gaps in each height direction, so that the height of the plurality of shelf boards 2 from the bottom plate 4 and the interval between each shelf board 2 can be selected. It is configured.

In addition, the engaging pins 9 disposed on the window/right side panels 5 and 6.
It goes without saying that the corresponding parts 10 have the same height or the same distance from the bottom plate 4.

By the way, the engaging pins 9 and 10 disposed on the window/right side plates 5 and 6 are fitted into fitting holes 12 formed in each of the side plates 5 and 6, as shown in FIG. It is composed of a section 13 and a support section 14 that supports the shelf board 2.

Then, the fitting portion 13 is inserted into the fitting hole 1 of the left and right side plates 5 and 6.
2, and is detachable.

Therefore, when installing the shelf board 2, the engaging pins 9 and 10 may be fitted into the fitting holes 12 at desired positions in the left and right side plates 5 and 6, if necessary.

Further, on the rear side of the rack main body 1, the above-mentioned engagement pin 9,
A plurality of beams 15 are attached across the left and right side plates 5 and 6 at positions that at least correspond to the placement positions of the beams 10.

A support pin 17, which is a locking portion protruding from the back side 16 of the shelf board 2 when the shelf board 2 is mounted, is placed on the support pin 15.

When the shelf board 2 is attached to the rack body 1, the back surface 16 of the shelf board 2 is supported.

As mentioned above, the rack main body 1 constituting the present invention has a locking part for the shelf board 2 so as to support the mounted shelf board 2 from three directions: the left and right side boards 7 and 8 and the back part 16. Since the engaging pins 9, 10 and the lever 15 are provided, the shelf board 2 is reliably supported.

In particular, the shelf board 2 is sufficiently long, and even if the audio equipment placed on the shelf board 2 is heavy, it can be reliably supported without bending.

In addition, since the shelf board 2 is mounted so as to be placed on the engaging pins 9 and 10 and the levers 15 provided on the rack main body 1 as shown in FIG. 3, the shelf board 2 can be easily attached and detached. It is also easy to move the mounting position.

Furthermore, in the above-described embodiment, the back side of the rack main body 1 is provided with an appropriate interval between the racks 15. is only attached, so even if a device that generates high heat, such as an amplifier, is placed on the shelf board 2, the heat dissipation effect will not be hindered.

Further, the unused beams 15 on which the support pins 17 of the shelf board 2 are not placed can also be used as guide members for wrapping the wiring cord.

However, as shown in FIG. 4, a back plate 19 is attached to the back side of the rack main body 1, in place of the rails 15, and has a through hole 18 into which the support pin 17 of the shelf board 2 fits. But that's fine.

In this case, the support pin 17 is inserted and fitted as shown in FIG. 5, thereby supporting the back surface 16 of the shelf board 2.

As mentioned above, the present invention has a shelf board that can be detachably engaged with a rack main body that is open at least on the front side so that the operating section of the audio equipment placed on the shelf board can be exposed to the outside. Since the shelf board is supported from three directions, it is possible to prevent the shelf board from bending when audio equipment is placed thereon, and to provide sufficient strength.

Furthermore, ease of attaching and detaching the shelf board can be ensured.
