Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for attaching a carrier such as a hanging belt or a handle.

Various attachment devices have been proposed for carrying devices such as belts or handles for carrying electronic devices such as tape recorders and radio cassettes. Because of this structure, an extremely strong unidirectional force is applied to the stud holder, which may cause the stud holder to come off or cause metal fatigue and breakage during repeated use. many.

In addition, the cover of the conventional mounting device has a structure in which a spring biases the cover in the closing direction when the cover is closed, and the cover can stand up when the cover is opened, so the rotation shaft of the cover is held between the cover body and a leaf spring. be.
As a result, the fulcrum of rotation of the cover is floating, and the cover is opened in an abnormal (forced) direction, often resulting in damage to the cover.

The present invention is proposed in order to solve the disadvantages of this type of conventional mounting device at once, and its main purpose is to provide a belt, etc., that securely locks the cover and has high mechanical strength and durability. There is a place to suggest equipment.

Another object of the present invention is to propose a mounting device having a cover that has a fixed fulcrum of operation and is easy to operate.

Other objects and features of the present invention will become clear from the detailed description based on the following examples.

First, the overall structure of the mounting device will be explained with reference to FIG. 1, which shows a typical embodiment. The fixture 1, integrally molded from plastic having a certain strength, consists of a connecting part 2 and a body part 3 for receiving a stud and housing a cover 5. The cover 5 is provided with a fulcrum 6 for opening and closing, and the cover 5 is attached to the fixture 1 by fitting the fulcrum 6 into a fitting hole (not shown) in a side surface 7 formed by a molding part. The cover 5 is integrally molded from plastic resin, and includes a pillar 8 and a lock lever 9, each of which has an arcuate surface facing the stud S so as to circumferentially surround the stud S extending from the circular device body. do. In the molding part of the fixture 1,
When the cam surface 11' of the cam 11 rides up on the single protrusion 10 formed integrally during molding, the lock lever 9 provided on the inner surface of the cover 5 in front of the fulcrum 6 and the protrusion 10 The structure is such that the cover 5 is biased in the closing direction.

As shown in FIG. 3, the fixture 1 has a take-in hole 12 for taking the stud S into the main body and an engagement hole 1 for maintaining the taken-in stud S in an engaged state.
3 are provided consecutively. Note that reference number 14 is a notch through which the belt 15 is passed.

The operation of the attachment device, such as a belt or handle, will now be explained with reference to FIG.

When the cover 5 in the state shown by the solid line is applied with a fingertip to the farthest end from the fulcrum 6 and force is applied, the cam surface of the cam 11 at the tip of the lock lever 9 gradually rides on the protrusion 10 (the lock lever is not bent at this time). nothing),
Next, step over the edge 5' of the cover 5 to step 1.
Rotate until it collides with 6. Therefore, the stepped portion 16 functions as a limiter. Following the opening of the cover 5, the stud S is taken in through the take-in hole 12, and after the stud S is moved to the engagement hole 13, the cover 5 is closed. When you press the tip of the cover with your finger, the lock lever 9 bends and the cam surface 11 moves into the protrusion 1.
0 in the opposite direction to the previous direction, and when the protrusion 10 rides on the cam surface 11' (the state shown in FIG. 1), the column 8 falls into the take-in hole 12. At this time, the protruding portion 10 forming the cam surface and the cam surface 11' are in an engaged state so as to bias the cover 5 in the closing direction. Therefore, even with the biasing force of the lock lever 9 engaged with the protrusion 10, the lever 9 and the pillar 8 sandwich the part of the fixture 1 centered on the protrusion 10, thereby locking the mounting device. It is. In the locked state, various forces act on the pillar 8 from the stud, and even if the pillar 8 is in the direction of the protrusion 10, the pillar 8 is restricted by the end 12' of the intake hole 12, and the lock is released. It's not something you can do. It is preferable that the pillar 8, which prevents the stud S from moving into the receiving hole 13, has such a length that it almost comes into contact with the main body of the device so as to sufficiently engage the stud S and the end portion 12'. The attachment device according to the present invention can also be connected to the handle 18 (FIG. 4). In this case, if the handle 17 of the handle 18 is configured to be pivotable at the connecting portion 2, it can be used as a detachable handle.

Since the present invention is constructed and operates as described above, the force from the stud is distributed over the pillar, and the pillar is reliably locked by the biasing force of the lever and the hole for receiving the stud. Therefore, in addition to being safe when carrying the device, the force from the studs is dispersed, increasing durability. Furthermore, since the fulcrum of the cover is formed at the furthest point when viewed from the point of action during operation, extremely small force is required when opening and closing.
Since it is only allowed to rotate in a predetermined direction without rattling, damage to the cover can be prevented, and the stud can be attached and detached with a light touch, making it extremely practical.
