Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is a push-type kannon clasp for a watch band, and more specifically, it does not return even if the pusher of the opening / closing plate is released when the push button is pushed to release the opening / closing plate. It is related to Kannon Nakadome that facilitates the deployment of the connected lid plate.

[0002]

[Prior art]

 Japanese Utility Model Publication No. 6-28009 discloses this type of Kannon Nakadome. This publication discloses a double-sided watch band stopper having wing pieces that are folded and deployed at both ends in the longitudinal direction of a strip, and a hook for holding one of the wing pieces and a wing piece for holding the other wing piece. An upper lid provided with a toe is rotatably attached, and a guide wall for inserting and guiding both wing pieces when the both wing pieces are folded is formed on both sides of the strip plate in a longitudinal direction and the guide wall is formed. A one-touch clasp having a keyhole for forming the notch of the upper lid on the intermediate part of the strip so that the push operation part projects laterally from the notch. It describes a double-sided watch band stopper that is equipped with.

[0003]

[Problems to be solved by the device]

 However, this publication has a problem that it is difficult to deploy the upper lid 20 because the upper lid 20 has to be deployed and rotated while the latching claw 20 is unlocked by pushing the push operation unit 12.

[0004]

[Means for Solving the Problems]

 According to the present invention, a push-latch hole member that has push button portions on both sides and a latch shaft that push-opens a latch hole and a latch shaft are provided in the middle of a lower plate that is formed in a horizontally long shape. An opening / closing plate for opening and closing is attached to one of the opening / closing plates, and a latching claw for hooking / unhooking the hooking shaft is provided on the inner surface of the one opening / closing plate. In a push-type kannon clasp that is provided with a lid plate attached to the front part, a spring for flipping up the opening / closing plate on the lid plate mounting side is attached to the middle of the lower plate to solve the problem. It is something to solve.

[0005]

[Action]

 In the present invention, when the push button is pushed to unlock the opening / closing plate, the spring for flipping up lifts the opening / closing plate, so that the unlocking state continues even when the pusher is released. Can be done smoothly.

[0006]

【Example】

 Embodiments will be described below with reference to the drawings.

A push hook hole member 3 formed by projecting push button portions 2a and 2b on both sides is attached to the middle of a horizontally elongated lower plate 1. The push retaining hole member 3 is provided with a retaining hole 3a which is spring-biased so as to expand when the push button portions 2a and 2b are pushed and contract when the push button portions 2a and 2b are released.

Opening and closing plates 4a and 4b that open and close in a double door type are attached to both ends of the lower plate 1 in the longitudinal direction, and a hook 5 is provided on the inner surface of the tip of the open and close plate 4a. The lower shaft 1 is hooked and unhooked on a hooking shaft 6 which is provided in the middle of one side.

In addition to vertically arranging a protrusion 7 that hooks into and disengages from the locking hole 3a on the inner surface of the front end of the opening / closing plate 4b, a widened mounting cylinder portion 8 is provided at the tip to mount the mounting holes in the side walls 9a and 9b of the lid plate 9. A pin 11 is fixed between 10a and 10b to attach a cover plate 9. Reference numeral 12 is a stepped surface provided in the middle of the opening / closing plate 4b, from which the front end of the opening / closing plate 4b rides on the push hook hole member 3 when it is closed and rotated.

Further, on the closing and rotating side of the opening / closing plate 4b of the lower plate 1, there is attached a ridge 13 that flips up the opening / closing plate 4b when releasing the latch. Reference numerals 14a and 14b are metal or leather type watch bands that are pin-connected to the opening / closing plate 4a and the cover plate 9.

When closing the Kannon Nakadome, the opening and closing plates 4a and 4b are closed and rotated on the lower plate 1 in this order. The hook 5 of the opening / closing plate 4a is hooked on the hook shaft 6, and then the protrusion 7 separates the hook hole 3a to enter the hook hole 3a and the hooked portion of the protrusion 7 is inserted. At the return of the stop hole 3a, the constricted portion is sandwiched and the protrusion 7 is hooked, so that the cover plate 9 is attached across the opening / closing plates 4a and 4b.

When opening, the push button portions 2a and 2b are pushed to open the latch hole 3a against the spring bias, and the protrusion 7 is unlocked. At the same time, the opening / closing plate 4b is flipped up by the spring 13 for flipping up and the opening / closing plate 4b is left unlatched, so that the handle is expanded from the push button portions 2a, 2b to the cover plate 9. Thus, by opening and closing the opening and closing plates 4a and 4b, the band loop is expanded and inserted around the wrist.

[0013]

[Effect of device]

 As described above, according to the present invention, in the push-type Kannon Nakadome, since the spring for flipping up is provided on the lower plate and the open / close plate on the lid plate mounting side is flipped up when the latch is released, By replacing the cover plate with the cover plate, the cover plate can be smoothly deployed.
