Description

  This invention relates to a detachable fastener for a necklace.

Conventionally, as a detachable fastener for a necklace, there are a pull ring type shown in FIG. 5A and a folded leaf spring type shown in FIG. 5B.
JP 2003-102523 A

  However, this type of fastener has a problem that it is difficult to attach and detach because the wearer performs the attaching and detaching operation where the wearer cannot see the back side of the neck. The pulling ring type and folding leaf spring type are suitable for necklaces made by connecting small rings, etc., but they are not used for necklaces with a blocky block piece and are difficult to mount. .

  The present invention is a male / female detachable fastener that attaches and removes a necklace for body decoration or a necklace that also serves as a health aid by connecting a number of frames, and one female fitting is a C-shaped body. The other male fitting has a hooked opening and closing plate and tongue piece, and the opening and closing plate enters the C-shaped body and the tongue piece is inserted into the guide groove. Attach between the male and female brackets at the neck, and unfold the latch between the male and female brackets by pushing open the opening / closing plate. This is because it is extremely easy to attach and detach at the margin.

  In the present invention, the opening and closing plate of the male fitting can be quickly hooked to the female fitting simply by entering the C-shaped body of the female fitting, and the hook can be easily released and separated by pushing the opening and closing plate. Since it was made possible, an effect that the invisible attachment / detachment operation on the back side of the neck can be performed extremely smoothly is produced.

  Since the guide groove is provided on the back side of the C-shaped body, and the opening and closing plate is guided by fitting and contacting the tongue piece of the male metal fitting, the effect that the opening and closing plate enters without shifting up and down etc. Arise.

  Since the clasp is formed so as to be conspicuously wider than the necklace piece, the clasp can be quickly grasped when attaching and detaching.

  The detachable fastener of the present invention can be attached to both ends of the necklace by pin connection in the same manner as the piece body that connects both the female and male metal fittings, and is easy to install, and is well accustomed to the necklace made by connecting block pieces. It produces the effect of improving the quality of the necklace.

  A male / female detachable fastener that attaches and removes a necklace for a body consisting of many pieces connected to each other or a necklace that also serves as a health aid around the neck, and one female fitting is between the wings of the C-shaped body. A latching shaft and a guide groove are provided, and the other male metal fitting has a hooked opening / closing plate and a tongue piece. Hang between the metal fittings, so that the male and female metal fittings are released by pushing open the opening and closing plate, and this fastener is formed so as to be conspicuously larger than the frame constituting the necklace, and on the back side of the neck This makes it extremely easy to attach and detach by hand.

  FIG. 1 to FIG. 3 show an example of a necklace 3 that is used as a necklace for body decoration or a health aid by connecting block pieces 1 and 2. The male metal fittings 6 are fixedly attached to the pins 7 in the same manner as the frame connections.

  The female fitting 5 has a C-shaped body 5a having a C-shape in a plan view and a retaining shaft 5b provided between both wings, and is provided with a guide groove 5c that is stepped on the inner back surface of the C-shaped body 5a. The male fitting 6 is provided with an opening / closing plate 6b with a flange 6a that enters the C-shaped body 5a of the female fitting 5 and a tongue piece 6c that fits into the guide groove 5c. 6d is a stop shaft for supporting the opening / closing plate 6b to be opened and closed, 6e is a winding spring for closing bias wound around the stop shaft 6d, 6f is an inclined surface provided on the front surface of the flange 6a, and 6g is an opening / closing plate 6b. It is the protrusion for pushing-opening provided in the base side upper surface of this. The fastener 4 is formed so as to be conspicuous by making it wider than the block pieces 1 and 2 constituting the necklace 3.

  When the fastener 4 is hooked, the opening / closing plate 6b of the male fitting 6 is advanced into the C-shaped body 5a. Then, the lower tongue piece 6c fits into the guide groove 5c and guides the opening / closing plate 6b. Therefore, the inclined surface 6f on the front surface of the flange 6a of the opening / closing plate 6b slides over the latching shaft 5b so that the collar 6a passes over the latching shaft. 5b will be applied. The fastening plate 4 is widened and the tongue piece 6c is fitted into the guide groove 5c, so that the opening / closing plate 5b can be easily entered and hooked regardless of the operation on the rear side of the neck. It will be.

  When unfastening the fastener 4, the projection 6g provided on the upper surface on the base side of the opening / closing plate 6b is pushed. When the winding spring 6e is compressed and the front part is lifted and opened, the flange 6a is lifted away from the latching shaft 5b to release the hook, so that it can be easily released by pulling and retracting the male fitting 6 as it is.

  FIG. 4 shows an example in which the protruding portion 6g of the opening / closing plate 6b has an inclined shape 6h with good finger-holding, and the fastener 4 can be operated by one-touch operation in which the male fitting 6 is pulled and operated by placing a finger on the inclined shape 6h. It will be possible to solve the problem.

  The clasp of the present invention can be widely used as a clasp that can be used for a necklace formed by connecting block pieces of various shapes.
