Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a plurality of pins for one piece such as a tie pin or a badge having a high-quality jewel or the like to prevent rotation when the pin is attached. It is possible to engage and lock the socket-receiving fittings, which are individually fixed together, on each of the pins, and also to release them in one movement, and furthermore, to break the parallel state of each pin installed in parallel when installed. This invention relates to a device that prevents falling off by providing a

[Technical background]

In the structure of conventionally known tie pins and badges, the jewel part and letter plate part rotate, and furthermore, (the pin rotates on its axis).
It is easy to fall off, and the expensive jeweled part is lost along with the pin, leaving only the insertion bracket and the chain.

The reason for this is that the mechanical and physical structure functions at first, but the pins gradually wear out each time they are put on and taken off repeatedly, or due to twisting and turning during use, and their accuracy deteriorates. It becomes dull, and furthermore, dust and the like get into the inside of the pipe of the receiving fitting and gradually become easy to come out.

It is true that the majority of people who have experience in owning tie pins have lost them due to falling out, and for this reason, experienced people have no desire to purchase expensive tie pins. They have the disadvantage that the more expensive they are, the more they are avoided, and the more expensive they are, the more they will affect the sellers.

[Conventional technology]

It was in 1977 that a form in which two needles were provided in one accessory to correspond to the plurality of pins of the present invention was devised.
It is published in Publication No. 13100.

Furthermore, the basic structure of a socket-receiving metal fitting in which the pin is immovable between the tapered surface and the pin is disclosed in Japanese Utility Model Application Publication No. 107010/1983.

Furthermore, a configuration in which two pins can be tightened and loosened with one slider is disclosed in Japanese Utility Model Application No. 59-6909.

[Problem to be solved by the invention]

The purpose of this invention is to prevent tie pins, badges, etc. from rotating when they are attached, and to prevent the attached attachments from falling off.

[Means to solve the problem]

As a means for achieving the above-mentioned object, the present invention provides an insertion receiving fitting that tightens and loosens the outer periphery of an inserted pin by moving a ball connected to a tapered surface. A plurality of holes for the balls are provided in the orthogonal direction through the claws, and each hole is slightly shifted in the axial direction, and the holes are bored at equal angles to engage the balls. A coil spring is inserted between the piston pipe and the pin receiving member, and its elasticity is inserted into and engaged with the taper hole of the piston pipe to urge the large diameter portion of the hole that engages the ball to always move toward the small diameter portion of the tapered hole. A metal fitting is formed by enclosing it against the metal plate, and a plurality of pins to be engaged and locked in this metal fitting are arranged in parallel, and a fixing seat provided with a decorative object such as a jewel attached at right angles is engaged. In order to do so, the same number of pins as the single pin of the insertion receiving fitting are arranged in the same arrangement as the pin arrangement, and the displacement position is such that it can be received, and the displacement position is engaged with the inserted piston pipe. Each taper pipe is fixed with a pedestal so that the ball setting positions are symmetrical, and each piston pipe has a collar provided at the end thereof that is integrally formed with the connecting part so that the ball is in a parallel position. The piston pipe is configured to simultaneously impart a movement motion to the pin receiving member that widens the gap between the pedestal and the connecting portion.

[Effect]

In order to prevent a single fixed seat with a decorative object such as jewelry from rotating when attached to a tie or cloth such as clothing, multiple pins are attached at right angles from the fixed seat.
In addition, the pins are installed so that they are parallel to each other, and then the individual insertion brackets can be independently engaged and locked to each of the individual pins so that the fixing seats do not fall out. A plurality of balls that engage with the piston pipe of the insertion receiving fitting are provided at a displacement position slightly shifted in the axial direction, and this displacement position is set on the piston pipe of the other insertion fitting with balls configured in the same manner as described above. By making the position symmetrical to the displacement position of the pin, each parallel pin is subjected to a tightening action that breaks the parallel relationship, thereby doubling the tightening action and preventing the pin from falling out. If the ball is installed in a displaced position in the insertion bracket, the tightening effect will be lower than that of the ball installed in the same diameter direction, but if it is installed symmetrically, the effect will be enhanced. The above effect can only be achieved by attaching a plurality of socket-receiving metal fittings.

Then, the pin receiving members of the plurality of insertion receiving fittings are solidified into one body with a pedestal, and a collar with piston pipes provided at the ends thereof is integrally formed via a connecting part, and the above, the pedestal, and the connecting part are integrally formed. By applying a widening operation to the gap formed by the two, each insert receiving member can be operated at the same time.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings. The piston is inserted into the inner piston with an insertion receiving fitting 23 which tightens and loosens the outer periphery of the pin 17 to be inserted by moving the balls 7 and 7' joined to the tapered surface. A hole 8 for a plurality of balls 7, 7' is provided in the pin hole 3 of the pipe 2 through a countersunk pawl 9 in the diametrical direction.
8' are each slightly shifted in the axial direction,
The holes 8 and 7' are drilled at equal angles to engage the balls 7 and 7', and are inserted into and engaged with the tapered holes 12 of the pin receiving member 16.
A coil spring 10 is connected to the piston pipe 2 and the pin receiving member 16 so that the large diameter portion 6 having a diameter of 8' always moves toward the small diameter member of the tapered hole 12.
Insert the metal fitting 2 against its elasticity and insert it in between.
3, and a plurality of pins 17 to be engaged and locked to this insertion receiving fitting 23 are arranged in parallel, and in order to engage a fixing seat 19 provided with a decorative object such as a jewel 18 attached at right angles, A displacement position in which the number of single pins 17 of the insertion receiving fitting 23 is arranged in the same manner as the arrangement of the pins 17, so that the pins 17 can be received, and the pins 17 are engaged with the inserted piston pipe. Each tapered pipe 15 is fixed with a pedestal 22 so that the balls 7, 7' are set in symmetrical positions, and each piston pipe 2 is connected with a collar 5 provided at its end. The piston pipe 2 is integrally formed with the pin receiving member 16 which widens the gap size between the pedestal 22 and the connecting portion 24 in the parallel position, and is configured to be able to simultaneously impart a movement motion to the piston pipe 2.

In the figure, reference numeral 1 denotes a small diameter part 4 that surrounds a coil spring 10 between a large diameter part 6 and a collar 5, which have holes 8 and 8' for engaging balls 7 and 7' in the piston pipe 2; is the large diameter part toward the end from the tsuba 5, 11

〔Effect of the invention〕

As described above, providing a plurality of pins from one fixed seat to which a decorative object such as a jewel is attached has the effect of preventing rotation of the decorative object.

The pin receiving member engages and locks each of the plurality of pins, and the securing force is reliably effective.

By integrating the individual pin receiving members with the pedestal and the connecting part to form the insertion receiving fitting, the ball is displaceably mounted on each piston pipe, which results in a synergistic effect with other pin receiving members and a wave of lateral force. This has the effect of imparting an action to break the parallelism to each pin that should be parallel, thereby strengthening the locking relationship between the plurality of pins and the insertion fitting.

By fixing the individual pin receiving members together with the pedestal and the connecting portion, and using the gap formed by the parallel pedestals and the connecting portion as the operation space, it is possible to operate the individual pin receiving members all at once. .

It has many effects such as
