Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a fastener for opening and closing the opening of handbags, bags, and other bags.

(Prior art) Conventional fasteners for bags, etc. have an M-shaped spring embedded inside a female-shaped stopper, and a male-shaped stopper is provided with an engaging part formed in the center of the M-shaped spring. The bulge at the tip of the engagement protrusion was engaged or pulled out to fix or disengage, but if used for a long time, there was a risk that the M-shaped spring would weaken and the bulge would easily come off.

In addition, in recent years, donut-shaped permanent magnets have been used to make female and male stops for bags, etc., using the magnetic force of the permanent magnet. However, there were drawbacks such as changes in the magnetic card, making it impossible to use the magnetic card.

(Problems to be solved by the invention) This invention improves durability without causing the M-shaped spring to weaken and stop acting as a stopper, as in the case of conventional methods, or without changing the magnetic card as in the case of using permanent magnets. The object of the present invention is to provide a fastening device of excellent mechanical construction that can be widely used for handbags, bags, and other bags.

(Means for Solving the Problem) The present invention forms a male stopper 1 from metal, synthetic resin, ceramics, wood, etc., and attaches a push rod 2 (or a push piece that presses the push rod 2) to the male stopper 1. 3) is penetrated so as to be vertically movable, and a spring 5 is installed inside the male stopper 1 so that it can be pressed with a press rod 2 in the cylindrical part 4, and the engagement is divided into two or more parts provided below the cylindrical part 4. The upper ends of the pieces 6 and 7 are engaged with the receiving member 8 in a freely openable and closable manner, and a spring 5 is attached to the upper ends of the engaging pieces 6 and 7.
the lower ends of the engaging pieces 6,
Expanded portions 11 and 12 that engage with the locking hole 10 of the female stopper 9 are formed on the outer side of the lower end of the press rod 2, and a expanded portion 13 that pushes open the expanded portions 11 and 12 is formed at the lower end of the press rod 2. This is a fastener for bags, etc., in which the press rod 2 is housed inside the engaging pieces 6 and 7.

In addition, the male stopper 1 and the receiving member 8 are used to clamp and fix the lid (or container) of the bag, and the female stopper 9 and the stopper plate 14 are used to clip the bag to the container (or lid). It is used by attaching it in place.

(Function) The present invention forms a bulging portion 13 at the lower end of the push rod 2 that penetrates the male stopper 1, and the bulging portions 11, 12 of the engaging pieces 6, 7 are divided into a plurality of pieces. Since the bulge 13 is located inside the ampulla 11,
12, the lower ends of the engaging pieces 6, 7 are open.

With the lower ends of the engaging pieces 6, 7 open, align the male stopper 1 with the female stopper 9, and push the male stopper 1 toward the female stopper 9 to release the engaging pieces 6, 7. engages with the edge of the locking hole 10 formed in the female stopper 9, and the engaging pieces 6,
7 is pushed upward, and the bulging part 13 becomes the bulging part 11,1
2, the lower ends of the engaging pieces 6, 7 can be moved inward, and the enlarged parts 11, 12
comes inward and penetrates the locking hole 10 , and when the locking pieces 6 and 7 pass through the locking hole 10 , the press rod 2 rises due to the upward force of the spring 5 , and the bulge 13 moves to the bulge 11 . , 12, the enlarged portions 11 and 12 that have passed through the locking hole 10 engage with the lower edge of the locking hole 10, and the male-type enlarged portions 11 and 12 do not escape from the locking hole 10. The stopper body 1 and the female stopper body 9 are joined to close the lid and container of the bag.

Next, when the push rod 2 or the push piece 3 is pressed, the bulge 13 at the lower end of the push rod 2 will be moved to the bulges 11 and 1 of the engagement pieces 6 and 7.
2, the engaging pieces 6 and 7 can move inward, so that the enlarged portions 11 and 12 have an outer diameter smaller than the diameter of the locking hole 10 and can be removed from the locking hole 10.

Therefore, when fixing the male stopper 1 to the female stopper 9, simply push the male stopper 1 in the direction of the female stopper 9, and the enlarged portions 11 and 12 of the locking pieces 6 and 7 will engage. It is locked to the lower surface of the stop hole 10. Moreover, in order to separate the male stopper 1 from the female stopper 9, push the push rod 2 downward and pull up the male stopper 1, and the male stopper 1 can be separated from the female stopper 9. I can do it.

(Example) The present invention will be explained as an example of a device made entirely of metal material, in which a push piece 3 is attached to a disc-shaped male stopper 1 and has a flange that prevents it from escaping from the male stopper 1. The press rod 2 whose head is engaged with the lower part of the push piece 3 is made to protrude downward, and the spring 5 is installed inside the cylinder part 4 provided on the male stopper body 1. The upper end is engaged with the receiving member 8 provided below, and the lower part engages the engaging pieces 6 and 7 that open and close inwardly or outwardly,
The spring 5 is pressed against the engagement pieces 6 and 7, and enlarged portions 11 and 12 are provided on the outside of the engagement pieces 6 and 7 to be engaged with the engagement holes 10 of the female stopper 9, and the push rod 2 is inserted into the cylinder. 4, the spring 5, and the engaging pieces 6, 7. A bulge 13 is provided at the lower end of the push rod 2 and can protrude downward from the bulges 11, 12, and the bulge 13 is enlarged. When it is in the position of parts 11 and 12, the ampullae part 11,
12 is locked to the lower surface of the locking hole 10, and when the bulging part 13 protrudes below the position of the enlarged parts 11, 12, the engaging pieces 6, 7 move inward, so that the enlarged parts 11, 1
Reference numeral 2 denotes a stopper for bags or the like that can be taken in and out through the locking hole 10.

To explain the operation of this embodiment, since an arcuate or tapered portion is provided inside the enlarged portions 11 and 12 whose lower ends are opened by the pressure of the spring 5, the outer periphery of the enlarged portion 13 has an arcuate or tapered portion. Due to the tapered shape, the enlarged portion 1 is formed in the locking hole 10.
When the arcuate or tapered portions on the outer periphery of bulges 1 and 12 are easily slid in, the enlarged portions 11 and 12 are brought inward, and at the same time the arcuate or tapered portion on the outer periphery of the bulge portion 13 is moved inward. In order to make the bulging part 13 of the press rod 2 slightly protrude when it is pressed and slide, and to bring the tips of the bulging parts 11 and 12 inward, the bulging part 1
1 and 12 pass through the locking hole 10, and the enlarged portions 11 and 1
2 passes through the locking hole 10, when the press rod 2 is slightly pulled up by the tension of the spring 5, the bulging portion 13 rises slightly inside the bulging portions 11 and 12.
The lower ends of the ampullae 11 and 12 are opened outward and the ampulla 1
The outer peripheries of 1 and 12 are engaged with the locking hole 10, and the male stopper 1 is locked with the female stopper 9.

Next, when the press rod 2 is pushed downward, the bulging part 13 protrudes downward from the inside of the enlarged parts 11 and 12, so the enlarged parts 11 and 12 can move inward, and the pushing rod 2 is pushed downward. If the male stopper 1 is pulled up in this state, the male stopper 1 can be separated from the female stopper 9.

Note that the drawings are shown on a larger scale than the actual product.

(Effects of the invention) As described above, the present invention provides the male stopper with an engaging piece that can be freely opened and closed below the engaging piece, and the engaging piece is provided with an enlarged portion that engages and disengages with the locking hole of the female stopper. The male stopper is engaged with the female stopper by positioning the bulge provided at the lower end of the push rod on the male stopper in the enlarged part and allowing the bulge to escape below the enlargement. Since the parts can be separated from each other, each part will not deteriorate with long-term use, and since it has a mechanical structure, it can withstand long-term use without affecting magnetism. It is sufficient to press the push rod only when releasing the stopper. Further, when the two stoppers are engaged, the push rod is simply pushed, so it is extremely simple to use.
