Description

Buckle provided with a belt release mechanism {a buckle provided a belt release appratus}

The present invention relates to a buckle mating with a belt having a continuous sawtooth coupling groove, more specifically by engaging the engaging piece of the buckle to the sawtooth coupling groove formed continuously in the longitudinal direction in the center of the back of the belt. In the buckle which can fix a belt in arbitrary positions, it is related with the buckle provided with the mechanism which can release a belt more simply and reliably.

Conventional techniques related to the present invention include Utility Model Registration Nos. 4268 (1996.5.23) and 229759 (2001.4.25).

The Utility Model Registration No. 4268 (1996.5.23) is provided with two rods on the back of the buckle, that is, a cylindrical rod having a latch and an inclined guide groove, and a housing having a built-in spring and a push rod on the back of the buckle. Due to the complicated structure and the large number of components, the productivity is low, the production process is complicated, and as a result, the production cost is high.

On the other hand, Utility Model Registration No. 229759 (2001.4.25) solves most of the shortcomings of Utility Model Registration No. 4268 (1996.5.23), which reduces the number of parts and simplifies the structure. It was possible to lower productivity and improve productivity, but in order to adjust the belt length or to release the belt, the wearer pushes the pressing plate of the operating rod by putting the hand on the back of the buckle and adjusts the length of the belt in the public seat or in the face of the opposite sex. There is a downside to being very unnatural.

The present invention is to improve the above-mentioned disadvantages of the prior art, and provides a mechanism that the belt wearer can easily and reliably release the belt from the outside of the buckle in a range that does not impair the basic structure of the buckle according to the prior art. The technical problem to be achieved by the present invention is to improve or modify the components of the conventional buckle to the extent necessary for this purpose.

Fig. 5 is an exploded perspective view of the buckle according to the prior art, showing a dimensional correlation.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

5 is an exploded perspective view of the buckle of the prior art Utility Model Registration No. 229759 (2001.4.25), in the case of the buckle according to the prior art, in order to adjust the length of the belt or to loosen the belt, the belt wearer has a circumferential surface of the operating rod. Pressing the pressing plate (P) protruding on the pressing belt 23 formed on the opposite side of the pressing plate is rotated in the counterclockwise direction to the structure that can be released from the toothed coupling groove provided on the belt back to release the belt It can be seen that.

The problem is that the pressing plate is installed on the back of the belt and is basically located where it is inconvenient to operate, and the wrist and the arm must be raised to stick the finger between the belt and the pants. At the heart of the problem is that taking such an action if the other party in the front of the wearer is in the official seat of the wearer's face is reasonably inconvenient or unnecessarily misleading.

Accordingly, the present invention provides a belt release mechanism that adds a belt release mechanism having a different structure from the conventional one, and operates easily and reliably without taking the unnatural operation as described above in the belt wearer's release of the belt.

First of all, in order to naturally release the belt, the belt release means is operated on the outside of the buckle and the operation for release of the belt is performed on the inside of the buckle, i. Using the thumb, the belt release means exposed to the outside of the buckle is naturally pushed in the horizontal direction.

Next, a mechanism necessary for converting the linear motion into a rotational motion is added and a deformation is applied to the shape of the component according to the conventional art.

1 is an overall perspective view of one embodiment according to the present invention, and FIG. 2 is a partially exploded perspective view showing the belt release mechanism in the buckle of FIG.

Referring to the configuration of the buckle plate 10 shown in Fig. 2, the wall A (with an anti-rotation groove 11a, a coupling hole 11b, and a guide hole 11c) is formed at the top of the rear surface of the metal plate having various decorations on the front surface thereof. 11 is located, the wall B 12 is formed on the opposite side of the wall A, the wall B (12) having a coupling hole (12b) formed on the bottom of the back of the metal plate, the belt hanger rod 13 for connecting the wall A and the wall B up and down ) And a belt insertion guide rod (14).

The over-rotation preventing groove 11a and the over-rotating protrusion 24 described below prevent the operating rod 20 from being excessively rotated clockwise (based on a plan view) by the torsion restoring force of the spring inserted therein. It is not intended to provide the basic functions necessary for the present invention, but, when the belt is fitted, the belt engaging piece 23 of the operating rod, which will be described later, is slightly separated from being stuck to the bottom of the back of the buckle (thickness of the belt). Smaller than) provides a function that makes the belt more convenient to fit.

Therefore, the buckle of claim 1 discloses a type without the over-rotation preventing groove 11a and the over-rotating protrusion 24.

The actuating rod 20 has a pipe shape in which one side is blocked, and at one end, a journal 21 to be inserted into the coupling hole 11b of the wall A is formed, and an incision 22 is formed at the other end of the opening. , Overhang prevention projection formed on the outer peripheral surface of the circumferential edge formed with the belt engaging piece 23 and the side └ shape in the └ shape of the belt engaging piece 23 is inserted into the toothed coupling groove installed on the back of the belt by the force of the spring to the outer peripheral surface (24) and the operating rod rotation arm 25, the center line is located at a predetermined angle (θ °) away from the belt engaging piece and the projection 26 is formed on the upper surface, and the spring engaging jaw (27) to the inner bottom of the pipe Is formed.

FIG. 3 shows that, in an embodiment of the present invention, the angle θ ° is in the range of 45 ° ≦ θ ° ≦ 135 ° in the clockwise direction with respect to the belt engaging piece 23.

The actuating rod rotating arm 25 is a release knob 51 to be described later to change the linear movement along the guide hole (11c) formed in the wall A (11) to the rotational movement of the actuating rod, a constant from the center of the actuating rod When a lateral force applied to the release knob 51 is applied to the protrusion 26 separated by the length through the connecting rod 53 to be described later, a rotation force (moment) is generated in the operating rod to rotate the operating rod.

The actuating rod stopper 30 has a pipe shape in which one side is blocked like the actuating rod, and the member is coupled to the actuating rod with the opening facing the opening of the actuating rod. On the blocked side of the operating rod 30, a fixing protrusion 31 to be inserted into the coupling hole 12b of the wall B is formed, and an anti-rotation protrusion 32 which prevents rotation by restoring force of the spring inserted therein on the outer circumferential surface thereof. In the bottom of the inner spring engaging jaw 37 is formed.

Meanwhile, when the actuating rod stopper 30 is coupled to the opening of the actuating rod, the coil rod spring 40 is inserted into the actuating rod and the actuating rod stopper, and then the actuating rod stopper is turned counterclockwise (in the direction in which the actuating rod is inserted). When pushed into the incision 22 of the operating rod in the state of turning several times), it is the same as the prior art. At this time, the belt engaging piece of the operating rod is always buckle due to the torsional restoring force generated by the cutting surface of the element wires at both ends of the spring caught on the spring engaging jaw 27 and the spring engaging jaw 37 of the operating rod stopper. The back of the will be pressed.

Next, the belt release mechanism 50 will be described. As shown in Figure 2, the belt release mechanism is inserted into the guide hole (11c) of the wall A, the release knob 51 and the projection 52 of the release knob including a projection 52 for linear reciprocating motion And a connecting rod 53 having holes 53a formed at both ends thereof to connect the protrusions 26 formed on the protrusions of the operating rod, and screws 54 for coupling the connecting rods to the protrusions of the release knob. do.

The release knob 51 is a kind of button, and the belt wearer primarily receives the force required to release the belt from the outer surface of the buckle. The release knob 51 forms irregularities on the surface in order to transmit the force more easily. The shape of the release knob shown in Figs. 1 to 2 is a shape in which the central portion is bulging, but the release knob according to the present invention is not limited thereto and may be any shape as long as it is suitable for the purpose of the present invention. In other words, the center may be a hollow or flat shape.

A protrusion 52 having a circular cross section and a female screw formed at the center thereof is protruded to a predetermined length. The height of the projection 52 is long enough to penetrate the guide hole 11c of the wall A for guiding the linear movement of the release knob and the hole 53a formed at one end of the connecting rod 53 to be described later.

The connecting rod 53 is an element for converting a linear motion into a rotational motion, and holes 53a into which the projections 52 of the release knob and the projections 26 of the operating rod rotating arm 25 are inserted at both ends are provided. And the thickness L is slightly less than the height h of the cylindrical projection 26 formed on the actuating rod rotating arm for smooth operation.

The width of the guide hole (11c) of the wall A takes into account the diameter of the cylindrical projection 52 of the release knob, the length is constant in view of the amount of rotation (length) of the cylindrical projection (26) formed on the operating rod rotating arm It is decided with a margin.

In the buckle according to the present invention, the belt release mechanism is assembled by inserting the operating rod into the walls A and B with the connecting rod inserted into the operating rod, and inserting the opposite hole of the connecting rod into the projection of the release knob through the guide hole. Then, the screw 54 is fastened to the female screw hole formed in the center of the protrusion 52.

In a preferred embodiment of the present invention, the height h of the actuating rod rotary arm 25 projection 26 is lower than the height H from the edge of the actuating rod to the bottom of the rotating arm, and from the top of the protrusion to the edge of the actuating rod. Alternatively, the clearance gap Δh to the bottom surface of the wall A is made shorter than the thickness L of the connecting rod.

This prevents interference between the upper surface of the projection 26 and the bottom of the wall A 11 when the height h of the projection is equal to the height H from the edge of the operating rod to the bottom of the rotating arm, When assembling the rotary motion buckle, once the connecting rod is inserted into the protrusion of the operating rod rotating arm, it is not necessary to use a separate fixing means, while the connecting rod is pulled out through the gap (△ h) while the release mechanism is in operation. This is to avoid going out.

As described above, the buckle according to the present invention provides a product that is more commercially valuable to the consumer by providing a means for adjusting the belt length or releasing the belt more easily and naturally than the buckle according to the prior art. This is a very useful invention that can greatly contribute to the industrial development through domestic demand and increased exports.
