Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lock for locking a lid to a main body in a box such as a jewelry box or a cosmetic box.

[0002]

[Prior art]

 Such a lock is conventionally known. In this case, a pair of holders, each consisting of a ball and a support shaft, are mounted on the outer surface of the box body at a slight interval, and the outer surface of the box lid is equipped with a ball portion at the tip. The rod is attached rotatably in the vertical direction, and the lid of the box is locked to the box body by locking the ball portion of the locking rod between a pair of holding bodies.

[0003]

[Problems to be solved by the device]

 However, there are the following problems before the conventional sling lock. That is, since the locking rod attached to the outer surface of the lid of the box is rotatable in the vertical direction, when closing the open lid, the locking rod hangs vertically and the ball portion at the tip of the locking rod is moved. It collides with the holder on the box body side (see the chain line in Fig. 3). If the balls of the locking rod on the lid side collide with the holder on the box body side in this way, not only the lid will not close, but also the locking rod and the holder may be damaged. In order to avoid such a situation, the user must lift the lid-side locking rod upward when closing the lid, which is troublesome. The present invention has been made in order to solve the above problems.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is such that the lid-side locking rod is always lifted upward by a spring. That is, according to the present invention, a pair of holders each including a ball portion and a support shaft portion are mounted on the outer surface of the box body at a slight interval, and a ball portion is provided at the tip of the outer surface of the lid of the box. The locking rod is attached rotatably in the vertical direction, and the box portion of the locking rod is locked between the pair of holding bodies so that the box lid is locked to the box body. The lock bar is characterized in that the locking rod is always lifted upward by a spring.

[0005]

[Action]

 Before the sling lock according to the present invention, since the locking rod on the lid side is always lifted upward by the force of the spring, the ball portion of the locking rod on the lid side is close to the box body when the lid of the box is closed. (See the solid line in FIG. 3). Therefore, when closing the lid, the user should bring the lower edge of the lid into contact with the upper edge of the main body, and then the locking rod on the lid side resists the force of the spring and between the pair of support bodies on the main body side. Just push it in. When pushing the locking rod on the lid side between the balls of the support on the main body side, each support is temporarily expanded by the support shaft of the locking rod, but the locking rod is the ball on the support on the main body side. When passing through the spaces, each support returns to its original state again, and holds the locking rod. Therefore, as a result of the locking rod being locked between the pair of supports, the box lid is locked to the box body. When the lock is released, the locking rod on the lid side is rotated upward against the force of the spring to separate it from the pair of supports on the main body side. Also at this time, each support is once spread by the support shaft of the locking rod, but when the locking rod passes between the balls of the support on the main body side, each support returns to the original state again. To do.

【Example】

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. First, a conventional sling-shaped front to which the present invention is applied will be described. Reference numeral 1 is the main body of the box, and reference numeral 2 is the lid of the box. On the outer surface of the main body 1 of the box, a pair of holders 7, 7 each consisting of a ball portion 3 and a support shaft portion 5, are mounted at a slight interval. That is, as an example, as shown in FIG. 2, a mounting plate 9 having a shallow tray shape is fixed to the outer surface of the main body 1 of the box with screws 11 and 11, and the mounting plate 9 has a pair of through holes 13 and 13. The support shaft portion 5 of each holding body 7 is loosely fitted in each through hole 13, and each support shaft portion 5 is fixed to the leaf spring 15 inside the mounting bracket 9 having a substantially shallow tray shape. The spring 15 is fixed to the inner surface of the mounting member 9 by the fixing means 17. On the other hand, on the outer surface of the lid 2 of the box, a locking rod 23 having a ball portion 21 at its tip is attached rotatably in an up and down direction, and the ball portion 21 of the locking rod 23 is a pair of holding bodies 7 on the main body side. , 7 to lock the box lid 2 on the box body 1. That is, as an example, a mounting plate 25 having a substantially shallow tray shape is fixed to the outer surface of the lid 2 with screws 27, 27, and a pivot support 31 having a notch recess 29 in the center is fixed to the mounting plate 25. A locking rod 23 is attached to the cutout recess 29 of the pivotal support 31 via a pivot 33 so as to be vertically rotatable.

Therefore, in the present invention, the locking rod 23 on the lid 2 side is always lifted upward (to the right in FIG. 3) by the spring 41. As an example of the spring 41, as shown in FIG. 4, an annular portion 41a and an inclined portion 41b are integrally formed, and the annular portion 41a of the spring 41 is attached to the pivot body 31. It is clamped between the metal fitting 25 and the slanted portion 41b is brought into contact with the locking rod 23. Reference numeral 34 is a projecting portion projecting downward from the pivot body 31, and reference numeral 26 is a mounting hole formed in the mounting metal fitting 25 in correspondence with the projecting portion 34. In this case, the projecting portion 34 of the pivot body 31 is inserted into the annular portion 41a of the spring 41, and the projecting portion 34 is inserted into the mounting hole 26 of the mounting bracket 25 and caulked and fixed.

[0008]

[Effect of device]

 As described above, according to the present invention, since the lid-side locking rod is always lifted upward by the force of the spring, the lid-side locking rod ball is closed when the box lid is closed. The part does not collide with the holder on the box body side. Therefore, when the lid is closed, the locking rod and the holding body are not damaged by collision with each other, and the lid is smoothly closed. Therefore, the user does not need to lift the locking rod on the lid side every time the lid is closed.
