Description

[Detailed Description of the Invention] The present invention relates to a handle attachment mechanism for electrical equipment such as a cassette tape recorder with a radio.

Generally, a handle is attached to the body of electrical equipment such as a cassette tape recorder with a radio for carrying it around, but the conventional handle attachment mechanism requires a mount for rotating the handle in addition to the handle itself. However, there was a drawback that the number of parts increased.

The present invention was devised in view of these drawbacks, and will be described in detail below with reference to the drawings.

Figure 1 is a perspective view of a cassette tape recorder with a radio using the handle attachment mechanism of the present invention.
, and a rear lid 2.

At both left and right ends of the upper portion of the rear lid 2 that extends between the back surface 11 and the top surface 12, narrow groove-like fitting recesses 4, 4 into which the substantially U-shaped handle 3 is inserted are formed.

The width of the fitting recesses 4, 4 gradually becomes narrower toward the front.

Reference numerals 7 and 7 designate fitting holes provided in the side surfaces 13, 13 of the fitting recess 4.4 and penetrating to the side surface 14.14 of the rear lid 2.

The front lid 1 is formed with elastic protrusions 5, 5 which are inserted into the fitting recesses 4, 4 of the rear lid 2.

Reference numerals 6 and 6 indicate linear protrusions provided on the protruding piece 5.5.

The handle 3 has a circular fitting protrusion 8.8 that fits into the fitting hole 7, 7 provided on the side surface of the fitting recess 4, 4 of the rear lid 2.
is formed.

Further, on the back surface of the fitting projections 8, 8 of the handle 3, a linear groove 9 is formed in the transverse direction, as shown in FIG.

The procedure for attaching the handle to the case using the handle attaching mechanism of the present invention having such a configuration will be explained.

Now, as shown in FIG. 4, when inserting the handle 3 into the fitting recess 4°4 of the rear cover 2, the handle 3 is inserted as shown in FIG.
Since the shape of the fitting recess 4 of the rear cover 2 is narrower toward the front with respect to the insertion direction, when the handle 3 is inserted into the fitting recess 4゜4 from the rear of the rear cover 2, the handle 3 is deformed and receives elastic force due to the deformation, and as shown in FIG. 6, the circular fitting protrusion 8 of the handle 3 is fitted into the fitting hole 7, and the handle 3 is attached to the rear cover 2.

However, in this state, the handle 3 has only been deformed and there is a gap 10 between the fitting recesses 4, 4, so although the handle 3 is attached to the rear lid 2, the stability is poor. When the handle 3 moves in the left-right direction and the front cover 1 is attached, the protruding piece 5 provided on the front cover 1 is moved from the front end opening 15 of the fitting recess 4 to the fitting recess 4 as the front cover 1 is attached. The bundle 3 is inserted into the rear lid 2 to fill the gap 10, and the elastic force generated by the deformation of the protruding piece 5 presses the bundle 3 against the side surface 13 of the fitting recess 4 of the rear lid 2 (see FIG. 7).

Therefore, the instability of the nozzle 3 due to the gap 10 is eliminated.

Also, when carrying the case, put bundle 3 in the
As shown in the figure, by rotating the bundle 3 upward, the linear groove 9 provided on the bundle 3 and the linear protrusion 6 provided on the protruding piece 5 of the front cover 1 are aligned so that the bundle 3 is aligned with the rear cover 2. When the case reaches the top, the bundle 3 is in the most stable state because it is fitted, and the bundle 3 is in a locked state, so that the bundle 3 is stably attached when carrying the case.

As described above, the nozzle attachment mechanism according to the present invention has a fitting recess that becomes narrower toward the front at both left and right ends of the upper part of the rear lid, so that when the bundle is inserted into the fitting recess, The bundle is deformed, and the rear fitting protrusion is now fitted into the fitting hole provided on the side surface of the fitting recess of the rear lid, and the bundle is attached to the rear lid.

Furthermore, when the front cover is attached to the rear cover, the protrusion provided on the front cover is configured to urge the bundle in the side direction of the fitting recess, so that the bundle is stably attached and the bundle is easily attached. No special fittings are required, the number of parts is minimal for the front cover, rear cover, and bundle, and the manufacturing process has advantages such as simplicity and low cost.
