The present invention relates to a relocking member for locking a tape reel of a video cassette, and more particularly, to a relocking member in which a reel locker is formed of a single unit having elastic force and the peripheral shape and structure thereof are improved.

As shown in FIG. 1, the relocking member includes two relockers 10 and a release lever 12 attached to the sole 16 and the support 18 of the lower case 14, respectively. As the locker part 20 of 10) is engaged with the gear 24 of the tape reel 22 which forms the supply reel and the winding reel, the locking state in which the rotation of the tape reel is prevented is maintained, and the unlocking state is not shown. As the release bar 25 of the VTR pushes the release lever 12 through the hole 26, the lifting lever 12 moves up and down when the release lever 12 rotates about the hinge axis 28. The piece 30 rotates the rotation piece 32 of the relocker 10, and the taper 22 can be rotated by separating the rocker portion 20 rotated therefrom from the gear 24. will be.

By the way, in the conventional relocking member, as shown in FIGS. 1 to 3, the release lever 12 of the relocker 10 is provided with a support 16, a support pole 18, and the like. Due to the complicated configuration of the peripheral configuration, the manufacturing or assembly process is difficult, as well as the reel locker 10 must be equipped with an elastic member so as to always have the elastic force to hold the tape reel 22 due to the excessive number of parts There are many inconveniences in assembly and it has been an increase factor of manufacturing cost.

Such organic coupling of many parts is problematic in that there are many defects in operation, practicality is low, and productivity is reduced by slowing down assembly work.

Therefore, in the present invention, a monolithic locking member supported by a pole is manufactured, and a triangular piece that is horizontally retracted as the locking release rod of the VTR rises is formed to extend in the tension bar, and at both ends of the tension bar. LOCKING SERIF to lock the gear of the tape reel is formed, and the arc and the triangular piece are returned to their original position so that the locker is released from the tape reel gear as the tension bar is bent when the triangle piece is retracted. When it comes back (i.e., when the lock releases the rod descends), it returns to the restoring force (elastic force) applied to the tension bar, and the locking fines on both ends of the tension bar are rotated around the foul and are re-locked on the gear of the tapel reel to maintain the relocking It was made possible.

Therefore, assembling time is greatly saved by using the monolithic relocking member, cost reduction effect is greatly reduced due to the reduction of component requirements, and since it is operated as a single part, practicality and accurate operation are guaranteed.

The present invention described above is described in detail with the accompanying drawings.

Reel locking member according to the present invention, the tension bar 40 formed so as to be fitted to the pole 16, the fouling inlet 38 formed in the lower case 14, the tension bar 40 and both ends of the fouling A triangular piece 44 is formed at the end of the elastic support 46 extending horizontally with the locking fine granules 42 at the center of the tension bar 40 and the locking fine granules 42 formed at right angles from the sphere 38. On the triangular piece 44, up and down symmetrical inclined surfaces 48 and 50 are formed, and reference numeral 52 in the figure is a horizontal guide groove.

In addition, the lower case 14 on which the relocking member is installed is formed with a predetermined distance from the reeling member mounting wall 54, and a horizontal guide formed on the triangular piece 44 of the relocking member. Guide rails 56, in which the grooves 52 are slid, are installed in pairs around the hole 26, and the upper case 34 corresponding thereto has a fouling opening 58 and a triangular piece floating prevention rail 60. It has formed features.

Figure 4 is a block diagram of the relocking member of the present invention, (a) is a perspective view from the front position, (b) is a block diagram of the rear surface of the triangular piece (44), the overall shape of the mountain "16" "Shows the shape formed symmetrically in the shape of a child.

Here, both ends of the tension bar 40 are fitted with a fouling fitting 38 which is inserted into the foam 16 so as not to be separated, and the rocker support 62 is perpendicular to the fouling fitting 38 to lock the fine-grained 42. It is formed to support, the elastic support 46 in the same direction as the rocker support 62 is extended to support the triangular piece 44 toward the center of the tension bar (40).

In particular, the triangular piece 44 has the same operation and function even if the upper and lower inclined surfaces 50, 48 are formed symmetrically when the relocking member is inserted upside down.

For this reason, it is natural that the locking fine grain 42 formed at the end of the rocker support 62 is also formed to have a length that is vertically symmetric about the rocker support 62.

5 is a view showing the installation position and the installation portion of the subject innovation, Figure 6 is a state diagram in which the relocking member is pre-fastened to the lower case 14 in the subject innovation.

Accordingly, the locking fine grains 42 are interposed between the gears 24 of the tape reel 22 to be in a relocking state which prevents the drive of the tape reel 22.

In this state, when the unlocking rod 25 of the VTR is raised to release the relocking state, the lower inclined surface 48 of the triangular piece 44 is pushed up, but the triangular piece floating prevention rail 60 of the upper case 34 is raised. The triangular piece 44, which is suppressed by rising, is slid horizontally along the inclined direction, and the horizontal guide groove 52 is moved along the guide rails 56, so that the straight tension bar 40 is moved. The rocker support 62 rotates about the fouling hole 38 as much as the length of the ruler is reduced.

Accordingly, the locking fine grain 42 at the tip of the fouling fitting 38 is released from the gear 24 of the tape reel 22 to release the relocked state.

When the unlocking rod 25 of the VTR is lowered, the state as shown in FIG. 6 is maintained by the restoring force (elastic force) of the tension bar 40.

As described above, the present invention has a locking bar (42) and a triangular piece (44) formed by using the tension bar (40) as an elastic source. It can be eliminated, the quality is excellent, there is an effect that can be used practically.
