The present invention relates to a buckle used for connecting straps or connecting melvan belts of ski pants.

In this kind of buckle, two sets of buckle bodies that can be engaged with each other form a set, and when used to connect suspender belts of ski pants, for example, one side of the two buckle bodies is connected to the ski pants and the other side of the suspender belt is used. It is attached to the front end and the two buckle bodies are joined to each other to connect the front end of the suspender belt to the ski pants.

In this type of buckle, the separation operation is complicated because the buckle body on the other side must be operated while pressing the release operation button installed on the buckle body on one side during the separation operation.

Therefore, the Applicant releases the coupling state of both buckle bodies by inserting the buckle body of one side which is inserted in the coupling state of the two buckle bodies deeper into the buckle body of the other side, and then releases the buckle body of the buckle body again. We propose the theoretical bar push push type buckle which the buckle body of the one side which is inserted without being concerned about can come out of the buckle body of the other side. (Japanese Utility Model Publication No. 2092)

In the conventional push push buckle as shown in FIG. 10 and FIG. 11, the insertion part 12 of the first buckle member 10 on the male side of the second buckle member 14 on the female side is shown. When it is inserted in the receiving part 16, it is comprised so that it may be fastened. When the insertion part 12 is inserted into the receiving part 16, the protrusion 24 formed in the elastic piece 22 of the 2nd buckle member 14 and the tapered surface 18 formed in the front-end | tip of the insertion part 12, Abuts.

Further, when the first buckle member 10 is further inserted, the tapered surface 18 bends over the protrusions 24 while bending the elastic pieces 22, and by the elastic return force of the elastic pieces 22, FIG. As shown in the figure, the protrusion 24 is caught by the locking hole 20 so that the first buckle member 10 does not fall out in the direction of arrow B in FIG. 10 with respect to the second buckle member 14. At the same time, when the stopper member 26 formed on the second buckle member 14 and the elastically retractable stopper member 26 come into contact with each other, the insertion portion 12 moves in the direction of arrow B in FIG. Press to maintain the fastening state.

Further, in disengaging the fastening of the buckle, the first buckle member 10 is further moved in the direction of the second buckle member 14 (the arrow A direction in FIG. 11) while countering the holding force of the stopper member 26. Insert it. Then, the protrusions 24 ride on the block 28 and bend the elastic piece 22.

In this state, the first buckle member 10 is slowly detached from the second buckle member 14, and the block 28, which is slidably mounted in the engaging hole 20 of the first buckle member 10, has a protrusion ( When the 24 is moved to the front end side of the insertion portion 12 and the first buckle member 10 is pulled in the direction in which it is detached (the direction opposite to the arrow A), the protrusion 24 moves on the block 28. By sliding and moving from the upper side of the engaging hole 20 to the tapered surface 18, the first buckle member 10 and the second buckle member 14 is released.

However, when the above-mentioned fastening state is released, the first buckle member 10 is slowly removed while the protrusion 24 is on the block 28, and the protrusion 24 is the block 28. There is a fear that the buckle may return to the locked state again by falling to the engaging hole 20 at the corner of

In view of the above circumstances, an object of the present invention is to obtain a buckle that can reliably and smoothly perform an operation for releasing the fastening by preventing the operation of the so-called push-push-type buckle from being re-engaged again. have.

The buckle according to claim 1 is a hollow receiving portion formed on the first buckle member, an elastic piece formed on the receiving portion and protruding a protrusion toward the hollow side, and formed on the second buckle member. An insertion plate inserted into the receiving portion, a locking hole formed in the insertion plate, and a block provided to be slidably movable in the locking hole. When the insertion plate is inserted into the receiving portion, the locking hole is formed in the protrusion of the elastic piece. The first buckle member and the second buckle member are engaged, and the second buckle member is further pushed into the first buckle member, and the protrusion of the blade elastic piece is put on the block and the extraction operation of the second buckle member is pulled out. In the buckle is guided to the outside of the engaging hole by the release buckle to release the engagement state of the first buckle member and the second buckle member, the protrusion of the elastic piece to the block A guide piece for guiding to the outside of the locking hole is formed.

The buckle according to claim 2 is characterized in that the guide piece protrudes outward from the locking hole in a state where the block is in contact with the hole wall of the locking hole.

In the buckle according to claim 1, when fastening the first buckle member and the second buckle member, the insertion plate of the second buckle member is inserted into the receiving portion of the first buckle member. By doing so, the tip of the insertion plate is abutted out of the protrusions, is inserted into the receiving portion while deforming the elastic pieces, and the protrusions are inserted into the catching holes to be in a locked state. Accordingly, the second buckle member is engaged with the first buckle member so that the fastening state is not released.

Subsequently, when releasing the fastening of the buckle, if the second buckle member is strongly pushed into the first buckle member, the guide piece of the block deforms the elastic piece while sliding with the protrusion, and the elastic piece returns elastically when the guide piece passes through the protrusion. The stone climbs on the block.

Here, when the second buckle member is pulled out, the block pressed by the protrusion slides in the locking hole to abut against the hole wall, thereby restricting the movement. Further, when the second buckle member is pulled out, the protrusions slide up the guide piece while slidingly pushing the block against the hole wall, and move outward from the top of the locking piece at the top of the guide piece.

In this way, at the moment when the protrusion passes over the guide piece by forming the guide piece, the protrusion can reliably move to the outside of the locking hole due to the difference between the height of the guide piece and the locking hole. Therefore, there is no fear that the buckles will fall between the engaging holes and the block, and the buckle will be locked again.

In the buckle according to claim 2, the guide piece projects outward from the locking hole in a state where the block is in contact with the hole wall of the locking hole. Therefore, the protrusion guided by the guide piece is reliably guided outward of the locking hole.

EMBODIMENT OF THE INVENTION Hereinafter, the Example of the buckle of this invention is demonstrated by FIG. Incidentally, in Figs. 1 to 9, the parts corresponding to the conventional examples shown in Figs. 10 and 11 described above are denoted by the same reference numerals for convenience of explanation.

As shown in FIG. 1, the contracting second buckle member 10 and the female shaft first buckle member 14 are configured to be fastened and released.

The second buckle member 10 is composed of an insertion plate 12 and the attachment portion 30 of the belt. The insertion plate 12 has a substantially rectangular plate shape, and a tapered surface 18 is formed so that the tip of the distal end portion thereof is tapered. The tapered surface 24 to be described later is smoothly climbed on the tapered surface 18.

The rectangular engaging hole 32 is formed in the center part of the insertion plate 12. As shown in FIG. The locking projections 32 protrude from the locking holes 32 so as to restrict the movement range of the block 46 which slides in the locking holes 32.

In addition, open holes 36 and 38 are formed in both horizontal directions of the locking hole 32, and guide pillars 40 and 42 are formed between the locking hole 32 and the open holes 36 and 38, respectively. have. Guide protrusions 44 are formed on opposite sides of the guide pillars 40 and 42, respectively. As shown in FIG. 2, the guide grooves 48 formed on the side surfaces of the block 46 are engaged with the guide protrusions 44, so that the block holes 46 do not flow. It is designed to slide me.

On the other hand, the guide piece 50 whose cross section is a rectangular triangle shape is formed in the corner part of 46 A of upper surfaces of the block 46. As shown in FIG. On the inclined surface 50A of this guide piece 50, a ledge 24 to be described later slides up the upper surface 46A of the block 46, and the block 46 is pushed by the crushing force at this time. ), The mouth surface 46B is strongly pushed against the locking surface 20 of the locking hole 32. In addition, the block 46 is fitted in a state in which the two guide arms 40 and 42 are bent toward the open holes 36 and 38, respectively.

In addition, a belt fitting hole 58 is formed in the attachment portion 30 of the second buckle member 10, and the belt fitting hole 58 is fitted near the end portion of the belt 60.

On the other hand, the 1st buckle member 14 is comprised from the attachment part 64 for attaching the belt 62, and the hollow receiving part 66 into which the insertion plate 12 of the 1st buckle member 14 is inserted. The belt fitting hole 68 is formed in the attachment part 64, and the end part root of the belt 62 is fitted in this belt fitting hole 68. As shown in FIG.

The receiving part 66 is a flat rectangular parallelepiped having a hollow inside, and the insertion plate 12 of the second buckle member 10 is formed in the inner hollow portion of the receiving part 66 through the opening 70. It is intended to be inserted into 72. An approximately c-shaped slit 74 is formed on the upper surface of the receiving part 66, and the portion left after being cut is an elastic piece 22.

The elastic piece 22 is a cantilever-type female shape formed successively in the insertion direction (the arrow A direction in FIG. 1) of the 2nd buckle member 10, and the protrusion which protrudes into the buckle insertion path 72 at the front end. 24 is formed. As for the protrusion 24, the site | part which faced the opening hole 70 is the inclined surface 76. As shown in FIG. The inclined surface 76 comes into contact with the tip of the insertion plate 12 of the second buckle member 10 when the second buckle member is inserted, and inclines the elastic piece 22 to the outside of the buckle insertion path 72. Transform.

Moreover, the receiving part 66 is formed with the rectangular hole 78 in the edge part on the opposite side to the opening hole 70. The rectangular hole 78 is formed with a cantilever arm 26 extending in a direction substantially perpendicular to the insertion direction of the second buckle member 10. At the free end of the cantilever arm 26, a projection 80 is formed to protrude into the buckle insertion path 72. As shown in FIG. The protrusion 80 has a tip end of the insertion plate 12 of the second buckle member 10 at a position where the protrusion 24 of the elastic piece 22 is caught in the engaging hole 32 of the second buckle member 10. The second buckle member 10 can not be inserted deeper if it is in contact with the open hole 70 and is not a predetermined or more insertion force.

Next, the method and operation of the buckle of the present embodiment will be described.

In fastening the second buckle member 10 and the first buckle member 14, as shown in FIGS. 3 and 4, the insertion plate 12 of the second buckle member 10 is disposed in the first buckle member. It is inserted into the buckle insertion path 72 of the receiving part 66 from the open hole 70 of the 14 (14). In this way, the tapered surface 18 at the tip of the insertion plate 12 abuts against the protrusion 24, and the slope 76 of the protrusion 24 smoothly rises the slope of the tapered surface 18 so that the engaging hole ( The protrusions 24 are caught by the catching holes 32 by falling into 32. Therefore, the second buckle member 10 with respect to the first buckle member 14 is in a fastening state that does not fall in the direction of the arrow B.

At this time, when the tip of the insertion tube 12 is in contact with the protrusion 80 of the cantilever arm 26, the insertion plate 12 is restricted from moving in the direction of arrow A, and imparting a force in the direction of arrow B. do. Therefore, the protrusion 24 is caught by the locking surface 20 of the locking hole 32 without flowing.

Subsequently, in releasing the fastening of the buckle 11, as shown in FIGS. 5 to 7, when the second buckle member 10 is strongly pushed in the direction of the arrow A, the tip of the insertion tube 12 is removed. The cantilevered arm 26 is pushed out while elastically deforming. By doing so, the guide piece 50 of the block 46 slides the elastic piece 22 to the outside of the buckle insertion path 72 while slidingly sliding with the inclined surface 76 of the protrusion 26. And when the guide piece 50 passes through the protrusion 26, the elastic piece 22 will elastically return and the protrusion 26 will ride on the upper surface 56 of the block 46. As shown in FIG. In addition, the insertion amount of the insertion plate 12 is limited by the stopper surface 71 which abuts against the open hole 70 of the receiving portion 22, so that the cantilever arm 26 is deformed too much and is not damaged.

Here, when the second buckle member 10 is pulled in the direction opposite to the arrow A, the block 46 pressed after the protrusion 26 slides in the locking hole 32 to be brought into contact with the locking surface 2. Movement is regulated.

Subsequently, when the second buckle member 10 is pulled out in the direction indicated by the arrow B, the protrusion 24 slides the inclined surface 50A of the guide piece 50 while pushing the block 46 strongly against the locking surface 20. The taper surface 18 moves out of the locking hole 32 by moving from the top of the guide piece 50 to the tapered surface 18.

In this way, at the moment when the protrusions 24 cross the top of the inclined surface 50A by forming the guide pieces 50, the protrusions 24 are reliably tapered by the difference between the heights of the guide pieces and the locking holes. 18). Therefore, there is no fear that the claws 24 will fall into the engaging holes 32 and the buckle will be locked again.

In addition, even when a step occurs between the upper surface 46A of the block 46 and the upper surface of the insertion tube 12, the protrusions 24 do not come into contact with the open hole edges of the locking holes 32, The protrusion 24 can move to the tapered surface 18 at the position of the gun.

In addition, when the protrusion 24 climbs the inclined surface 50A, the block 46 is pushed against the locking surface 20 so that there is no fear that a gap is formed between the block 46 and the locking surface 20. Therefore, there is no fear that the buckle 11 is brought into the fastened state again because the protrusions 24 fall in the gap between the block 46 and the locking surface 20.

In FIG. 8 and FIG. 9, the modification of the guide piece mentioned above is shown. That is, the guide piece 80 is formed successively so that the block 46 may incline toward the upper side from the corner portion, and the tip thereof protrudes forward from the elevation 46B. Therefore, when the protrusion 24 is located at the tip of the guide piece 80, it has already reached the outer side of the locking hole 32, so that it is reliably moved to the tapered surface 18 to release the fastening state of the buckle.

Since the buckle of the present invention is configured as described above, the operation for releasing the fastening can be performed reliably and smoothly without fear of becoming in the fastening state again during the operation for releasing the fastening.
