Description

BRACKET INTEGRATING THEREWITH A PLURALITY OF COMPONENTS ON A DECK IN A VIDEO CASSETTE RECORDER The present invention is directed to a bracket on a deck of a video cassette recorder(VCR); and, more particularly, to a bracket integrating therewith a pair of loading gear support shafts, a cassette guide pin and a sub-brake pivot shaft, separately positioned on a deck of a VCR.

On a deck of a VCR, a multiplicity of components are installed, some of which are illustrated in Figs. 1 to 3.

In Fig. 1, there is shown, between a pair of reel tables 20, a cassette guide pin 5 for properly seating a tape cassette(not shown) to be on a deck 10, when it is loaded into the VCR and for keeping the tape cassette properly in place after it has been seated on the deck 10. The cassette guide pin 5 is oriented upright above a surface of the deck 10 on which a head drum assembly HD is positioned. In installing the cassette guide pin 5 on the deck 10, so called "an outsert molding method" is used. In this case, the cassette guide pin 5 is normally made of a plastic or a material which is easier to handle than a metal.

In Fig. 2 showing the other side of the deck 10 in Fig.

1, there are illustrated a pair of loading gears 3 between a pair of pole base guide slots 12. Each of the loading gears 3 is rotatably supported around a loading gear support shaft 6. The pair of loading gear support shafts 6 are formed on the deck 10 by using the out-sert molding method mentioned above.

A sub-brake pivot shaft 8 is sectionally depicted in Fig.

3. The sub-brake pivot shaft 8 rotatably supports a subbrake(not shown) adjacent to a supply reel table positioned on the side of the deck having the head drum assembly. The subbrake pivot shaft 8 is formed on the deck with a different kind of material from that of the deck, by using the out-sert molding method.

All components listed above are formed on the deck with a different kind of material from that of the deck, employing the out-sert molding method. However, due to inherent difficulties in performing the out-sert molding method, such installation of the components may entail an increased manufacturing time and cost in the VCR manufacturing process.

Further, when the components installed on the deck using the out-sert molding method broke down or do not function properly, it is difficult to individually replace those components with new ones.

It is, therefore, a primary object of the invention to provide an improved bracket for integrating a pair of loading gear support shafts, a cassette guide pin and a sub-brake pivot shaft which can be easily installed.

The above and other objects of the invention are accomplished by providing a bracket on a deck of a video cassette recorder, the bracket comprising: a base plate; a pair of loading gear support shafts integrally formed with the base plate to vertically protrude from a surface opposite from the principal surface; a cassette guide pin integrally formed with the base plate to vertically protrude from the other surface of the base plate; and a sub-brake pivot shaft integrally formed with the base plate to vertically protrude from the surface of the base plate on which the cassette guide pin is formed.

The above and other objects and features of the instant invention will become apparent from the following description of preferred embodiments taken in conjunction with the accompanying drawings, in which: Figs. 1 and 2 show top plan views of a prior art cassette guide pin and a pair of loading gear support shafts, respectively; Fig. 3 illustrates a sectional view of a prior art subbrake pivot shaft; Fig. 4 represents a schematic plan view of an integrating bracket in accordance with the present invention; Fig. 5 offers a top plan view of the integrating bracket in accordance with the present invention; and Fig. 6 presents an side elevational view of the integrating bracket in Fig. 5; and Figs. 7 to 10 depict sectional views of the integrating bracket, taken along lines A-A, B-B, C-C and D-D in Fig. 5, respectively.

Referring first to Fig. 4, there is shown an integrating bracket 100 positioned on a deck 10 of a VCR in accordance with the present invention. The inventive integrating bracket 100 has a base plate 60 and a plurality of components vertically extending from the base plate 60.

The integrating bracket 100 integrates a pair of loading gear support shafts 62 therewith, which rotatably support a pair of loading gears 3, respectively. The loading gear 3 serves to drive a pole base assembly(not shown) which performs a tape loading operation, moving along a pole base guiding slot 11.

Further the integrating bracket 100 integrates a cassette guide pin 65 therewith. The cassette guide pin 65 ensures that a tape cassette(not shown) is properly seated on the deck 10, when loaded into a VCR and the same is kept in place after seated on the deck 10.

Moreover, an intermediate gear boss 63 is integrally formed with the inventive integrating bracket 100. An intermediate gear(not shown) is a component on the deck 10 which rotates the pair of loading gears 3.

Furthermore, a sub-brake pivot shaft 64 is integrally formed with the inventive integrating bracket 100. The subbrake pivot shaft 64 rotatably supports a sub-brake 50 adjacent to a supply reel table 40 on the deck 10.

The integrating bracket 100 constructed in this manner is fixed to the deck 10 through the use of screw S. For the fixing by the screw S, the integrating bracket 100 has a screw hole 61 formed therethrough.

Detailed description of the inventive integrating bracket 100 will be made with reference to Figs. 5 to 10.

As shown in Figs. 5 and 6, the pair of loading gear support shafts 62 and the intermediate gear boss 63 extend from one principal surface of the base plate 60, being perpendicular with respect to the latter 60. When the integrating bracket 100 is installed on the deck 10, two members 62 and 63 protrude above a surface of the deck 10 on which the pair of loading gears 3 are mounted(see Fig.4). The cassette guide pin 65 and the sub-brake pivot shaft 64 extend from the other principal surface of the base plate 60 in an opposite direction to the loading gear support shafts 62 and the intermediate gear boss 63. When the integrating bracket 100 mounted on the deck 10, those members 62 and 63 protrude above a surface of the deck 10 on which the supply reel table 40 is mounted(see Fig. 4).

The inventive integrating bracket is manufactured using an injection molding method. As shown in Figs. 7 to 9, the pair of loading gear support shafts 62, the cassette guide pin 65 and the intermediate gear boss 63 are processed to have cavities 62', 65' and 63', respectively, during the injection molding operation. As a result, less material is used in manufacturing the integrating bracket 100.

In Fig. 10, the sub-brake pivot shaft 64 is divided into a shaft 64b around which the sub-brake 50 substantially rotates, and a guide lug 64a which guides the pivot movement of the sub-brake 50(see Fig. 4).

Although the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
