DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bracket for mounting a device such as a CDROM drive on a chassis of a desktop personal computer (personal computer) or the like.

[0002]

2. Description of the Related Art In a desktop personal computer, a CDROM drive or an FD is inserted into a predetermined slot formed in a chassis.
Devices such as drives are removably fixed. To securely fix this type of drive device to the slot, two dedicated brackets are required on the left and right sides of the drive device, and in order to fix each bracket to the chassis, not only screws but also other Guide parts and fastening parts were also required. Therefore, the number of components is increased, and the work of mounting the drive device in the slot is complicated.

[0003] A left and right integrated bracket may be used for fixing the CDROM drive. In that case,
Although the number of parts is small and the mounting work is easy, the bracket itself becomes large, so that the unit price of the bracket increases and waste in terms of transportation costs and storage space occurs. Moreover, the left and right integrated bracket is
There is a drawback in that it is difficult to comply with the recycling system for home electric appliances, which has been increasingly legislated in recent years, which is disadvantageous in terms of reduction.

Conventionally, various brackets have been devised for securely fixing a drive device to a chassis or the like of a personal computer. However, in both cases, the tension of a spring-like member protruding from the chassis or the bracket is used, or guide rails are provided on the bracket and the chassis to which the drive device is fixed, and the friction therebetween is used. For this reason, with the conventional fixing method, when the accuracy of the mounting position of the component parts is insufficient, or when the holding force acting on the bracket is insufficient, the component cannot be firmly fixed to the chassis. Play was occurring. When the guide rail is provided to fix the bracket to the chassis as described above, the structure of the bracket becomes complicated, which leads to an increase in cost.

[0005]

As described above, the structure of the conventional bracket increases the number of components in mounting a device such as a CDROM drive to a chassis such as a desktop personal computer, and is disadvantageous in terms of cost. In addition, there is a problem that the attaching / detaching operation requires time.

An object of the present invention is to provide a bracket which can be attached and detached in a short period of time by reducing the number of components to reduce costs.

[0007]

To achieve the above object, there is provided a bracket which is inserted into a slot formed in a chassis of a first electronic device and fixes a second electronic device. The bracket is fittable to a base member fixed to a side wall surface parallel to a direction in which the second electronic device is inserted into the slot, and a pair of recesses formed in the side wall surface in the slot of the chassis. A slide member having a pair of convex portions and held by the base member in a state of being slidable in parallel with the direction of insertion into the slot.

In the bracket, when the second electronic device is inserted into the slot, the slide member and the base member are integrally inserted into the slot, and the inserted slide member is slid. As a result, the convex portion and the concave portion of the inner wall surface of the slot act to fit each other.
When installing various drives such as D and FD, or when disassembling, it can be easily and reliably attached and detached without using tools.
