Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an attachment for attaching a housing of a broadcasting electronic device such as a tuner device or an amplifier device to a rack.
[0002]
[Prior art]
Such a conventional case is often used by being mounted on a rack. An example of this type of rack is EIA-310, a rack standard (American Electronics Industry Association) that is highly used worldwide. There are two mounting holes penetrating in the front-rear direction on two pillars standing on both sides at a predetermined pitch, or two upper and lower holes at a predetermined pitch. Using the mounting holes and mounting portions provided in the housing, the housings are attached in a desired vertical arrangement so that the front panel is located on the front side. Thereby, for example, it becomes easy to operate a large number of electronic devices and the appearance is improved. In order to attach the chassis to the rack in this way, an attachment part is required on the chassis side, and the conventional attachment part is formed integrally with the chassis such as the front panel and side panel of the chassis, or on the side of the chassis. It is provided by screwing the fixture.
[0003]
In addition, the half-rack size chassis, which is half the rack mounting width of the rack, has insufficient width, so an extension panel that extends the front panel on one side of the chassis is attached with screws, A fixture is fixed to this with a screw, and the fixture is directly fixed to the other surface of the housing with a screw. Apart from this, it is conceivable to connect two housings together and mount them in a rack. In this case, a coupling tool for joining the casings is necessary, and the joining is performed by screwing the casings to the bottoms of the casings with plate-like members.
[0004]
[Problems to be solved by the invention]
When the fixture is formed integrally with the housing, the fixture becomes an obstacle when the device is used alone. Also, if the fixture is attached by screwing, it can be removed when not needed, but a tool is necessary and takes time. If the attachment is not attached to the housing during the manufacture of the equipment, it will not take time to remove the attachment when it is not needed, but it will take time and effort to install the attachment to the housing when necessary. is there. In other words, the rack mounting tool is necessary when the device casing is mounted on the rack, but is not necessary when the device is used alone. Therefore, when it is assumed that the device itself is used without being attached to the rack, it is important from the standpoint of increasing convenience that the fixture can be easily attached to and detached from the device housing.
[0005]
In addition, in the case of a half-rack size device casing, the arrangement of racks and the device casing to be joined together are not determined at the time of manufacturing the device, so that the fixture cannot be formed integrally with the casing. It is also wasteful to attach the fixture to the housing in advance. For this reason, it is necessary to appropriately attach the fixture and the coupling tool to the housing when the rack is attached. However, there is a problem that the installation by screwing requires a tool and is troublesome.
It is an object of the present invention to provide an attachment that can be easily attached to a housing without using a tool, and to facilitate the use of a coupling tool in connection with the attachment.
[0006]
[Means for Solving the Problems]
The means of the present invention is provided on both sides of the casing so as to attach the casing for the electronic device to the casing support posts disposed on both the left and right sides at a predetermined interval, and on the outer side so as to substantially follow the front surface of the casing.

The convex portion is a flexible member that extends linearly in the front-rear direction of the housing. It is provided at the front end of the tongue-like portion having a configuration, and the relative movement of the housing and the fixture in the dovetail direction is locked in a fitted state of the concave portion and the convex portion. It is characterized (claim 1). There are cases where some of the devices installed in the casing are used by being installed in a rack, and cases where they are used alone. In mounting the equipment housing on the rack, the mounting groove can be easily attached to the housing by fitting the groove into the groove. When a housing with a fixture is used alone, the fixture is in the way, but this fixture is a natural groove fit, so it can be easily removed and used when not needed. . Further, in this configuration, the housing and the fixture can be fixed by the concave portion and the convex portion provided in both members without using fixing means such as screws. This fixed state is released by retracting the convex portion or the concave portion.
[0008]
The means is characterized in that the dovetail or dovetail groove on the housing side is formed by a member different from the housing so as to be detachable from the side wall of the housing (claim 2) . In this configuration, the housing is provided with the dovetail groove by attaching a member that is provided on the side wall of the case that is not provided with a fixture or has a dovetail groove, so that the simple case can be easily attached to the rack. It becomes possible to be able to.
