Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes a socket having a receiving portion and a plug,
The socket has an opening at one end communicating with the receiving portion and a mating edge adjacent to the receiving portion, and the plug has a resilient member that engages behind the mating edge when pushed into the receiving portion. The present invention relates to a separable buckle having a mating portion and an actuation portion coupled to the mating portion for unlocking the mating portion.

Such buckles are known in the art for separating and joining bands, belts, parts of handbags, girdles, parts of women's underwear, etc. The socket has a hole on one side, one edge of said hole extending transversely to the insertion direction of the plug acts as a mating edge that connects resiliently to the tongue of the plug. Normally, the tongues extend diagonally outward, so that during insertion of the plug into the socket, the tongues are temporarily deformed until they are in a position to engage the mating edges of the socket.

To unlock, place your finger in the hole and touch the tongue. Then, when the tongue piece is pushed down and transformed into the unlocked state, the plug must be pulled out and the buckle separated. When pulling out the plug, the tongue slides under the web of the socket and cannot be grasped by hand.

Therefore, separating known buckles requires the use of both hands, with one hand operating the tongue through the hole and the other hand pulling out the plug. There is also the disadvantage that the tongue is usually not in a position to completely fill the socket housing opening, so that the housing in this area has a visually undesirable recess.

It is an object of the present invention to provide a buckle that allows the socket and plug to be separated with one hand.

This object is achieved according to the invention in that the engaging part of the plug is arranged in front of the actuating part in the insertion direction of the plug, so that the actuating part is freely movable relative to the socket.

In the known buckle, the actuating part is located in front of the mating edge in the insertion direction of the plug, but the order of the actuating part and the mating edge is opposite to that of the buckle of the invention. While the actuating part of the known buckle slides together with the tongue under the web of the socket, the actuating part of the buckle of the present invention is exposed from the socket. Thus, the actuating part may be grasped by hand together with part of the plug during the entire operation of the separation. This can be done with one hand,
Therefore, there is no need to instantaneously and separately actuate the actuating part and the other parts of the plug.

Therefore, the buckle of the present invention is much easier and more convenient to handle than known buckles in terms of separation operations.

According to an embodiment of the present invention, the socket is provided with a notch that fits a part of the actuating part between the receiving part and the opening communicating therewith, and when the plug and the socket are connected, the actuating part partially fits into the notch. match.

This makes it possible to shorten the length of the engaging portion or the amount by which the engaging portion is deflected to unlock from the engaging edge.

In another embodiment of the invention, the plug is provided with an integral resilient tongue connected to its front end in the insertion direction.

The known buckle also has a resilient tongue, but the mating edge is at the free end of the tongue. In contrast, in the buckle of the present invention, the engaging portion is provided in the intermediate region of the tongue piece.

In another embodiment of the invention, the insert has an actuating portion located at the same level as the top surface of the socket. With this configuration, the actuating part is located flush with the outer contour of the buckle.
tb, giving the buckle a good appearance. Moreover, the actuating part can be operated by hand better than known ones located in the bore.

According to another embodiment of the invention, a mating part is provided with an inclined introduction part and with a mating shoulder extending transversely to the direction of insertion. This sloping lead-in portion allows for deformation of the mating portion and the mating shoulder catches behind the mating edge when the insert is fully inserted.

The mating edge of the socket may for example be formed by a lateral recess within the socket receptacle. Alternatively, in another embodiment of the invention, the socket is formed in the shape of a housing and a recess is formed in the inner wall of the receiving part in which the oblique lead-in fits. Due to the manner in which the mating parts of the invention operate, there is no need for the socket to be provided with holes. Rather, the socket may be molded as a closed housing.

When the buckle of the present invention is used for a band, strap, etc., in another embodiment of the present invention, a slit is provided at the rear end of the insertion portion to fit the end of the strap, and a fixing pin or rivet is provided. There is at least one cavity extending across the slot for such purpose. When molded from synthetic resin, the bottle may be formed integrally, but it is formed into a plug so that it can be easily torn.

According to another embodiment of the invention, the socket includes a receiving part;
It consists of three parts: a housing integrally containing at least one fixing bottle, and a fixing plate provided with a hole for receiving the bottle.

The fixing bin may be riveted to the fixing plate. or,
The whole or part of the circumferential surface of the bottle may be provided with teeth, which co-operate with claws in holes in the fixing plate. Furthermore, the fixing plate may be provided with a spring element adjacent to the hole, so that the spring element presses against the housing when the fixing plate is fixed to the housing. This elastic force accommodates lateral shear forces and prevents them from being applied to the locking bin. Moreover, the mating engagement of the locking pins provides the advantage of allowing the locking plate and housing to be separated, for example for fitting a new socket.

Embodiments of the present invention will be described below with reference to the attached drawings.

The buckle includes a socket 10 and a plug/l, and in FIG. 1 the socket and plug are in a connected state.

The plug (see FIGS. 2 and 3) has an insertion part 7.2 and a handle part /3. The handle part /3 is rectangular and has an open slot /lI at the rear end, into which the end of a strap or the like can be inserted. The upper piece above the slot in the handle has two bottles/! , /J are integrally molded so that they can be easily torn to pieces, and when driven, they tear apart and cross the slotted puffer fish, riveting the end of the strap inserted into the slot. A cavity is provided in the lower piece below the slot for the tip of the bottle to pass through.

The insertion part/2 is also rectangular, but the width is the same as the handle part/3.
It is slightly narrower and thinner than the . The insertion part /2 extends in the front-rear direction while maintaining a predetermined distance from each other, and the rear part has two slots /7 and /7 that reach the front half of the handle part 13.
lr, and the rear ends of both slots are connected by a transverse slot /9 formed in the handle part. This four)
/7, /I, /9 form a flexible tongue piece 20 connected to the front end of the insertion portion /2. The tongue has a thickened operating part 21 at its free end, and the upper surface of the operating part and the upper surface of the handle part 13 are at the same height. Actuating part 2/
The upper surface may be jagged as shown in the figure. On the tongue piece, in front of the actuating part 21, there is a serrated projection. The protrusion is sloped upward toward the actuating portion 21.

A distance is maintained between the protrusion n and the actuating portion 2/.

The front end of the handle has a contact surface.

In FIG. 3, an opening is provided in the actuating portion 21, into which the reflective piece 2j is fitted.

The socket 10 has the same thickness as the handle part /3, and the insertion part /
The housing has a housing 2A having a hollow receiving part 27 opened at the rear end with an opening 26 for receiving the housing 2A (FIG. 4). There is a recess 2t on the lower surface of the clay wall 30 of the receiving part into which the protrusion n of the insertion part/L2 fits perfectly, and behind the recess there are teeth 29 protruding downward that mesh with the protrusion later. The upper H3o then has a notch 31 that accommodates the front part of the working part, 2/, after the teeth. A recess is provided in the lower wall 32 of the receiving portion λ7.
2. r and a hole 33 for manufacturing reasons from which to mold the lower surface of the upper M30 in front.

Four bottles 311 protrude integrally from the four corners of the lower surface of the housing/2A. 3j is a rod-shaped fixing plate 3 that fixes the strap between it and the bottom surface of the housing/JA! (See also FIG. 1), and is provided with a hole 36 at a position corresponding to the above-mentioned bottle.

The IJ and thickness of the insertion part 12 of the plug // are such that it fits perfectly into the receiving part 27. Insert part 12 into receiving part 2
When the tongue piece 2o is inserted into the tongue piece 7 through the opening 2o, the protrusion 2o is pushed downward by the teeth, thereby causing the tongue piece 2o to bend downward. still,
The downward thickness of the tongue piece O is groove/7.

It is thinner than the outer part of it and is designed to bend downward as described above (see also Figure 3). When the insertion part is completely inserted into the receiving part in this way, the tongue piece and the protrusion n due to the restoring force of 20
snaps into the recess 2t, the protrusion n and teeth 29 engage, and the insertion part 2 is locked into the socket 10, and the socket and plug are connected. Incidentally, the front part of the actuating part 1 fits into the notch 3/ (see Fig. 1).

To unlock, grasp the handle part /3 with one hand and press down on the actuating part λl with your thumb, for example. As a result, the tongue piece 20 is bent downward, the protrusion n comes out from the recess 2g, and the tongue piece 20 is disengaged from the tooth 2wa. Plug II therefore comes out of socket lO.

Preferably, the socket 10 and the plug/l are molded from synthetic resin.

FIG. 7 shows a part of another example of the fixing plate, and FIG. 8 shows the lower surface of this fixing plate. A sleeve-like lug lO adapted to the bottle 3tl' is integrally formed on the plate 33'. A wall ll having a substantially semicircular hole at the upper end of the inner circumference of the sleeve IO
There is. The wall tI/ has a groove 41J parallel to the straight part of the semicircular hole, and the web groove between the straight part and the slot R meshes with the sawtooth lIS provided on the side of the bottle 3'. It has a protruding claw inside the hole. When the bottle 3' is pushed into the hole from above, the sawtooth IIj inserts the web p into the slot R.
is bent, and the claw is inserted into the hole and descends into the hole. Due to the restoring force of the web, the claw engages with the appropriate sawtooth Q and prevents the bottle from escaping upward. Fixed plate 35'
It may also be formed separately and fixed to the fixing plate with a flange at the upper end. Of course, the lug tio may be integrally formed on the fixed plate 35'. Also, the lug holes and the vias may be non-circular, such as semi-circular as described above, but may also be circular.

Furthermore, a disc spring-shaped collar 4Z4 may be provided integrally with the three lugs O or the fixed plate plate. This collar ψ6 is pressed against the lower surface of the housing when the fixing plate 33' is connected to the lower surface of the housing. The collar II6 adapts to the shearing force and acts so that no shearing force is applied to the fixing bottle 3'.

Such a connection between the housing and the fixing plate 35' is preferable from the viewpoint of assembly. Additionally, the fixed plate 35' can be separated from the housing by deflecting the web.
