Description

T-bar for connection {Bar for connection}

The present invention relates to a T-shaped bar for fastening, and more specifically, to a one-touch T-shaped bar for fastening that connects a watch strap for a wristwatch and a lug unit of the watch body.

The fastening bar is a metal bar that connects the watch strap to the lug unit of the watch body. Most existing watches are connected and fixed by the fastening bar. When the user needs to change the watch strap, he/she first removes the fastening bar from the lug unit of the watch body, then removes the watch strap, and reconnects the fastening bar to the lug unit of the watch body to connect the new watch strap.

However, when replacing watch straps with conventional technology, it is difficult to disassemble and assemble without special tools, making it very difficult to replace watch straps. Therefore, when replacing watch straps, users generally have to visit a watch repair shop to disassemble the watch and replace the watch strap, which reduces user convenience.

FIG. 1 is a drawing showing a one-touch fastening bar according to an embodiment of the present invention, and FIG. 2 is a drawing showing an exploded view of a one-touch fastening bar according to an embodiment of the present invention.

The fastening T-bar (100) according to the present embodiment (hereinafter, simply referred to as the fastening bar) is a connecting component between a watch strap (50) and a watch body (or lug unit), and the fastening bar includes a case (10), a button (30), a coupling pin unit (20), and a spring (40).

In this embodiment, the case (10) is a T-shaped structure having a space inside, and includes a hollow case (11) and a side case (10) attached to one side of the hollow case (11).

The inside of the hollow case (11) is formed with a hollow space (111), and the hollow space extends into the inside of the side case (10) to form an accommodation space (12) for providing a coupling pin unit (20) to be described later, and the accommodation space has an opening (12) that opens forward, and the opening (12) is closed by a cover (13).

The upper part of the side case (10) is provided with a protruding button hole (17) extending in the longitudinal direction. The protruding button hole (17) has a protruding wall (15) whose edge protrudes upward, and the inside of the protruding wall (15) is provided with a receiving space extending from the hollow space.

In this embodiment, the protruding button hole (17) is formed in the upper area of the side case (10) so that the button (30) can be accommodated, but it is not excluded that it is formed while spanning the upper area of the side case and the upper area of the hollow case. The protruding wall (15) determines a path so that the button (30) is guided when moved in the protruding button hole (17).

A button (30) is provided on the protruding button hole (17). The button (30) is a means for moving the coupling pins (41) along the hollow space inside the hollow case. For example, by moving the button (30) up and down in the receiving space, the coupling pins (41) can be moved left and right inside the hollow space.

The button (30) is accommodated in the protruding button hole (17) and includes at least two hooks (31). The hook includes a base portion (31a), a hook portion (31b), and a first inclined surface (31c). The hook (31) is installed on the bottom surface of the button and is formed toward the sliding block (42) to be described later. The base portion (31a) supports the cross-section of the button, the hook portion (31b) is bent and extended from the base portion (31a), and the first inclined surface (31c) is formed at the end of the hook portion (31b). At this time, the hook portion (31b) is installed at a position facing the locking pin (425) of the sliding block (42) and is coupled with each other.

That is, as the hook (31) is formed toward the sliding block (42), the hook portion (31b), which is the end of the hook, and the locking pin (425) formed on the sliding block (42) can be hook-coupled. This prevents the button from being detached from the outside of the first link (100).

The first inclined surface (31c) forms the same incline as the second inclined surface (424) of the sliding block (42) described later, so that when the first inclined surface of the button moves downward along the second inclined surface of the sliding block, both coupling pins (41) move inward.

The coupling pin unit (20) includes a sliding block (42) and a coupling pin (41).

The sliding block (42) includes a block connecting portion (420), an inclined block portion (423), and a fastening block portion (422). The connecting portion (420) is located between the inclined block portion (423) and the fastening block portion (422) to connect the two.

The inclined block part (423) includes a support part (427), a second inclined surface (424), and a locking pin (425). The support part (427) is a base part for forming the second inclined surface (424), and the second inclined surface (424) is formed on the support part (427). A locking pin (425) is formed at an end of the second inclined surface (424) and is connected to a hook part (31b) of a button (30). At this time, the inclined block part (423) is positioned in the receiving space.

The fastening block part (422) has a first extension part (428) that extends in the hollow direction of the hollow case from the connecting part (420) and a second extension part (429) that extends in the cover direction. The first extension part (428) has a fastening pin fastening hole (421) into which a fastening pin (41) is inserted, and the second extension part (429) has a notch (4291) formed. Accordingly, the fastening pin fastening hole (421) is located in the hollow interior of the hollow case, and the fastening pin is inserted into the fastening pin fastening hole (421).

The sliding block (42) is provided in two directions, and accordingly, the coupling pin (41) is also provided on both sides of the hollow case and is fitted into the coupling pin fastening hole (421) of the sliding block (42).

When the button is pressed, the sliding block (42) moves inward as the hook (31) of the button goes down along the second slope (424), and accordingly, the coupling pin (41) fitted into the coupling pin fastening hole of the sliding block (42) moves inward within the hollow space.

That is, the second inclined surface (424) in the sliding block (42) is an inclined surface that comes into contact with the first inclined surface (230), and the first inclined surface (230) and the second inclined surface (424) have the same directionality. Accordingly, the first inclined surface (31c) is formed to be upward as it goes toward the center of the protruding button hole (17), and the second inclined surface (424) is also formed to be upward as it goes toward the center of the protruding button hole (17) so as to have the same directionality as the first inclined surface (31c).

The coupling pin (41) passes through the coupling pin fastening hole (421) and is fastened with the sliding blower, and moves inside the hollow body as the button is pressed and released. When pressed, the end of the coupling pin (41) enters the cylindrical case, and when the button is released, the end of the coupling pin (41) is exposed to the outside.

The coupling pin has a case connection pin (411) and a spring connection pin (412) at both ends. The case connection pin is a part that is inserted into a connection hole in the watch case, and the spring connection pin (23) is a part that is inserted into the end of the spring (40).

A threaded portion (411) is provided on the inside of the spring connecting pin (23) to ensure a solid connection with the connecting pin fastening hole (421).

The spring (40) is fitted with spring connecting pins (412) at both ends, and when force is applied inwardly as the button is pressed, the spring (40) contracts, and when force is removed as the button (30) is removed, the spring (40) is relieved of contraction and returns to its original state due to elasticity.

Hereinafter, the operation of the present embodiment will be described. Fig. 3 is a first cross-sectional view showing a one-touch fastening bar according to an embodiment of the present invention, and Fig. 4 is a second cross-sectional view showing a one-touch fastening bar according to an embodiment of the present invention.

As shown in Fig. 3, as the button (30) is moved downward, the first inclined surface (31c) of the button moves outward along the second inclined surface (424), and the second inclined surface (21) of the coupling pin unit (20) moves inward along the first inclined surface (31) of the button, and as a result, the coupling pin (41) moves into the cylindrical case (11). Meanwhile, when the button is not pressed, as shown in FIG. 4, the force on the compressed spring is released and the button moves upward, so that the first inclined surface (31c) of the button moves inward along the second inclined surface (424), and the second inclined surface (424) of the sliding block (42) moves outward along the first inclined surface (31c) of the button. As a result, the case connecting pin (411), which is an end of the connecting pin (20) connected to the sliding block by the connecting pin fastening hole, moves to the outside of the hollow case.

Fig. 5 is a drawing of a state in which a one-touch fastening bar of an embodiment of the present invention is mounted on a watch strap. In a state like Fig. 3, the user can separate the watch strap (50) from the watch body or the lug unit, and in a state like Fig. 4, the user can connect the watch strap to the watch body or the lug unit.
