Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coupling device for an elastic claw plate and a claw receiver in which a claw receiver is fixed to one member to be coupled and an elastic claw plate is fixed to the other member so that they can be detachably coupled.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a coupling device is known in which a claw receiver is attached to one member to be coupled and a claw is attached to the other member so that they are simply fitted together.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional technique has a problem that even if the nail catches on the nail receiver, if the nail is weak, the nail may come off and the connection may come off.

[0004]

[Means for Solving the Problems]

 The present invention aims to solve the above problems, and forms a frame body consisting of both side walls and a top plate on a base, and a tapered guide groove at the center of the top plate inner surface and a locking groove at the tip of the guide groove. And a tapered guide projection that fits into the guide groove in the center of the upper surface of an elastic plate made of synthetic resin bent in an L shape, and the guide projection. The elastic claw plate has a stopper part formed at the rear end of the guide part that engages with the engagement groove and mountain-shaped engagement parts that engage with the locking edge parts on both sides of the guide protrusion. It is characterized in that it is detachably connected to the elastic claw plate.

[0005]

[Action]

 Insert the protruding part of the elastic claw plate fixed to one member to be connected into the guide groove of the claw receiving part fixed to the other member and guide the tip of the protrusion to the guide groove of the guide groove. Of the elastic claw plate is pressed at the position where the stopper part of the elastic claw plate passes through the guide groove, and the elastic claw plate that was deformed is returned to its original state by its own elasticity, and the stopper part is locked in the locking groove. Then, the engaging portions on both sides of the protrusion are engaged with the engaging edges of the claw receiver to be joined. When removing, push the elastic claw plate to remove the stopper from the locking groove and pull it out.

【Example】

 FIG. 1 is an external perspective view of a first embodiment of the present invention used for connecting an upper duct 1 and a lower duct 2. Next, the first embodiment shown in FIGS. 2 to 7 will be described in detail. Reference numeral 10 denotes a synthetic resin nail receiver, which forms a frame body on both sides 12 and 12 and a top plate 13 on a base 11. The top plate 13 has a protruding portion 15 having a tapered guide groove 14 on its inner surface. The guide groove 14 is integrally formed with a locking groove 16 at the tip thereof, and locking edges 17 are formed on both sides thereof. Reference numeral 18 is an elastic claw plate made of synthetic resin bent in an L shape, and a projection 19 which fits into the guide groove 14 is integrally provided at the center of the upper surface, and a tapered taper portion 19a is provided at the tip and a rear end is provided. A vertical stopper portion 19b is formed, and mountain-shaped locking portions 20 are integrally formed on both sides of the protrusion 19.

During use, the elastic claw plate 18 is fixed to one member to be coupled, for example, the upper duct 1, the claw receiver 10 is fixed to the other member, for example, the lower duct 2, and the projection 19 of the elastic claw plate 18 is fixed. Is inserted into the guide groove 14 of the nail receiver 10. The tip of the protrusion 19 is guided along the guide groove 14, is located on the center line of the guide groove 14, and when passing through the guide groove 14, the protrusion 19 that has been pressed and displaced by its elasticity is the original. Returning to the state, the stopper portion 19b is fitted and locked in the locking groove 16, and the locking portions 20 on both sides are locked by the locking edge portion 17 to prevent the coming off and the left and right positioning.

When removing, the protrusion 19 is pushed down, the stopper portion 19b is removed from the locking groove 16, and the elastic claw plate 18 is pulled out.

8 to 12 show a second embodiment of the present invention. Reference numeral 10 'is a claw receiver made of synthetic resin, and the top plate 13' has a flat upper surface, and a guide groove 14 ', a locking groove 16', and a locking edge portion 17 'are formed on the inner surface. The elastic claw plate 18 has the same structure as that of the first embodiment. The method of use is the same as in the first embodiment.

[0010]

[Effect of device]

 According to the present invention, a frame body including both side walls and a top plate is formed on a base, a tapered guide groove is formed in the center of the inner surface of the top plate, and a locking groove is formed at the tip of the guide groove. A pawl receiver having a toe and a tapered guide protrusion fitted into the guide groove at the center of the upper surface of an L-shaped bent elastic plate made of synthetic resin, and the locking at the rear end of the guide protrusion. It consists of elastic claw plates that form stoppers that engage with the grooves and mountain-shaped engagement parts that engage with the engagement edges on both sides of the guide protrusion. Since the tip of the elastic claw plate is guided and positioned to the position of the center of the claw receiving plate when it is connected, the locking groove allows the left and right positioning to be performed to ensure the prevention of slipping out. Wear.
