Description

  The present invention is a long band in a structure in which a plurality of pieces are connected, and convex portions and concave portions are formed on both sides of each piece, and these convex portions are inserted into and connected to the concave portions of adjacent pieces. The present invention relates to an adjustment mechanism for adjusting the height.

  Conventionally, in a band in which a convex part adjacent to a concave part of a piece is inserted and connected, in order to adjust the band length to be short, it is common to remove the piece from the band. Various structures have been proposed and implemented as methods / mechanisms for body removal.

  For the connection of the frame bodies, a structure using a connection pin for connecting the frame bodies is generally used. For example, a connection pin having a threaded portion at an end or an elastic connection pin is used. There are structures that can be attached to or removed from the frame.

  However, in the case of a connecting pin with a threaded portion and a long shaft structure that has elasticity, a relatively special jig such as a small screwdriver or tweezers is required to remove the frame, but it is necessary to prepare it immediately when necessary. It's not easy. Even if a jig is prepared, it is difficult for ordinary people to remove the connecting pin easily and smoothly because it requires an appropriate pull-out force, and sometimes the connecting pin is damaged. .

  Therefore, the present inventor has proposed a set of a band and an adjustment jig described in Patent Document 1 so that a general user can easily and easily perform adjustment as one of the inventors.

  The device described in Patent Document 1 uses an adjustment jig prepared as a set with a band by an operator, and inserts the shaft portion of the adjustment jig from the outside of the frame through the through hole and pushes it into the frame. By doing so, the moving member inside the frame body is moved by one end portion of the shaft portion, thereby releasing the locking between the connecting pin and the convex portion that connect the adjacent frame bodies and removing the frame body. It is a structure that can be used.

  As described in Patent Document 1, the adjustment jig suitable for removing the band piece is set with the band, so that even a general user can use the adjustment jig for simple work. Thus, the frame body can be removed and the adjustment can be facilitated.

Utility Model Registration No. 3169792

  The adjustment jig described in Patent Document 1 is prepared as a separate member from the band, and is used only when removing the frame. For this reason, since it is necessary for the band side to have a structure in which the adjustment jig can be inserted from the outside of the frame body into the frame body, a through hole is formed on the bottom surface side of the frame body so that the shaft portion of the adjustment jig is received. .

  However, in the band as an accessory to be worn on the body, if there is a through hole in the band and the opening of the through hole is always exposed to the outside, the internal mechanism of the band can be seen from the outside through the through hole, Even if it is the bottom side, it is not preferable in appearance.

  Further, the through hole cannot have a small diameter in order to pass the shaft portion of the adjusting jig. For this reason, dust such as sand and dust can easily enter the inside through the through-hole in which the opening is always exposed to the outside, and there is a risk of causing dirt on the opening and malfunctioning of internal components.

  Therefore, the present invention solves the conventional problems, and can easily and easily remove the frame body, solve the problem of the opening exposed to the outside, prevent decorative deterioration, and enhance the durability of the band. The purpose is to provide a mechanism.

  In the band adjusting mechanism of the present invention, a convex portion and a concave portion are formed on both sides in the connecting direction of the piece bodies, and a plurality of piece bodies are connected by inserting the convex portions into the concave portions of the adjacent piece bodies. In the configured band, the moving member provided with a connecting projection that removably engages with a part of the convex portion of the adjacent piece, and the connecting projection and the convex portion. A spring for biasing the moving member in a direction to maintain the locking with a part is provided, and the moving member is moved to release the locking between the connecting protrusion and the convex portion so as to be adjacent to each other. A band adjusting mechanism configured to remove the frame and adjust the band length, the shaft having an inclined portion that moves the moving member in response to an operating force on the convex portion, and a bottom surface of the frame The operation surface exposed to the outside from the through hole formed on the side An adjustment member formed on the frame, and the shaft portion is disposed inside the frame body, and the upper surface of the operation surface portion is substantially flush with the opening end portion of the through hole. It is formed so as to cover the opening portion of the hole, and the operation member of the adjusting member is pushed down, and the moving member is moved against the biasing force of the spring by the inclined portion of the shaft portion. .

  The band adjusting mechanism according to the present invention is characterized in that an inclined surface portion is formed at a portion of the moving member that contacts the inclined portion of the shaft portion.

  The band adjusting mechanism according to the present invention is characterized in that a portion for preventing the adjusting member from falling off from the convex portion is provided.

  In the band adjusting mechanism of the present invention, the adjusting member is configured such that the shaft portion is disposed inside the frame body, the upper surface of the operation surface portion is substantially flush with the opening end portion of the through hole, and covers the opening portion of the through hole. Because it is provided on the frame body, there is no need to search for a jig for removing the frame when performing an adjustment, and the adjustment member provided on the frame body can be easily and easily removed. It can be carried out.

  Furthermore, since the upper surface of the operation surface portion of the adjusting member is substantially flush with the opening end portion of the through hole and covers the opening portion of the through hole, the through hole is closed to the outside except when the piece is removed. In addition, it is possible to prevent the occurrence of problems such as dust, sand, dust and the like entering the inside through the through-holes and adhesion of dirt on the opening. For this reason, it is possible to prevent the occurrence of malfunction of the internal parts, improve durability, and prevent decorative deterioration.
