Description

  The present invention relates to a holding mechanism for securely holding a portable device such as a wireless microphone, a cellular phone, and a portable music player, and a portable device including the mechanism.

  Conventionally, in order to detachably attach a portable device to a belt, it is known to provide a belt clip mechanism for hooking the belt on a case housing the portable device (see Patent Document 1). That is, by inserting and fixing the belt clip mechanism to the belt, it becomes possible to hold the portable device without having it in hand.

  However, the conventional belt clip mechanism has a structure in which the force of the spring is used for holding, and the usability changes significantly depending on the hardness of the spring. For example, if the spring is hard, the risk of dropping the portable device is reduced, but it is difficult to attach and detach. Conversely, if the spring is soft, it is easy to attach and detach, but the risk of dropping the portable device increases.

In addition, since many belt clip mechanisms are fixed so as not to rotate with respect to the portable device, there is a problem that it is difficult to use because the orientation of the portable device cannot be changed after mounting. In order to solve this problem, a structure for supporting the portable device in a rotatable manner has been proposed (see Patent Document 1). However, the direction of the portable device is easily changed depending on the magnitude of the force for attaching the portable device to the belt clip mechanism. Conversely, a new problem has arisen that it is difficult to rotate the portable device.

  Hereinafter, one embodiment of a holding mechanism according to the present invention will be described in detail with reference to the drawings. As will be appreciated by those skilled in the art, the illustrated embodiment is merely an example of the present invention and is not intended to limit the present invention.

  In FIG. 1, the portable device 1 that faces the object to be attached when attached to the object to be attached such as a rear panel 11 of the portable device 10 such as a wireless microphone, a mobile phone, or a portable music player, that is, a belt. The holding mechanism 20 according to the present invention is detachably and rotatably mounted on the panel surface. In order to realize this, as shown in FIG. 2, a flat and circular clip base 12 is fixed to the center of the back panel 11 of the portable device 10 with screws or the like, and a holding mechanism is attached to the clip base 12. 20 is detachably and rotatably mounted. Since the clip base 12 having a certain thickness is interposed between the portable device 10 and the holding mechanism 20, a slight space is formed between the portable device 10 and the holding mechanism 20. It becomes easy to rotate the mechanism 20 with respect to the portable device 10.

  As shown in FIGS. 3A and 3B, the holding mechanism 20 includes a substrate 21 attached to the clip base 12 by a detachable screw 30 and a belt or the like connected to one end of the substrate 21 and between the substrate 21. A clamping piece 22 for sandwiching an object to be attached and a lock lever 23 for switching the holding mechanism 20 between a locked state and an unlocked state are provided. An opening having a diameter through which the attaching / detaching screw 30 can pass is provided in the upper center of the holding piece 22 (FIG. 4). It is desirable that the substrate 21 and the sandwiching piece 22 are integrally formed of an elastic body, or are integrally connected by an elastic body to bias the sandwiching piece 22 away from the substrate 21.

  A shaft 24 is provided at one end of the clock lever 23, and the shaft 24 is rotatably supported by a support body 25 provided at an appropriate position of the substrate 21. As a result, the clock lever 23 rotates about the shaft 24 so as to switch the holding mechanism 20 between the locked state and the unlocked state. Therefore, as shown in FIG. 3A, when the lock lever 23 is tilted toward the back panel 11 of the portable device 10, the holding mechanism 20 is locked and the holding piece 22 is pushed toward the substrate 21. Thus, an object to be attached such as a belt can be sandwiched between the substrate 21 and the sandwiching piece 22, and the portable device 10 can be reliably held. When the lock lever 23 is raised from this state to the state shown in FIG. 3B, the force to push the holding piece 22 is lost, and the holding piece 20 is released from the substrate 21 and the holding mechanism 20 is unlocked. The device 10 can be easily removed.

  4A and 4B show an example of the configuration of the lock lever 23 for switching the holding mechanism 20 between the locked state and the unlocked state. A clamping piece 22 is provided around the shaft 25 of the lock lever 23. FIG. A protrusion 26 shaped to lock the lock lever 23 while being pushed toward the substrate 21 and a flat shape capable of releasing the lock lever 23 by releasing the clamping piece 22 from the substrate 21. A portion 27 is formed. That is, as described above, the clock lever 23 can be rotated around the shaft 24, and when the lock lever 23 is pushed toward the portable device 10, the protrusion 26 is moved along the shaft 24 as the lock lever 23 rotates. As a fulcrum, the clamping piece 22 is pushed toward the substrate 21, and the lock lever 23 is locked in this state. On the other hand, when the lock lever 23 is raised, the protrusion 26 comes off the holding piece 22 and comes into contact with the flat portion 27 as the lock lever 23 rotates, and the holding piece 22 moves away from the substrate 21. In other words, the protrusion 26 and the flat portion 27 of the lock lever 23 are arranged such that the shortest distance between the center of the shaft 24 and the flat portion 27 is shorter than the shortest distance from the center of the shaft 24 to the protrusion 26. Formed at the base. Thus, the lock lever 23, the shaft 24, the protrusion 26, and the flat portion 27 constitute a lock mechanism of the holding mechanism 20.

  Further, as shown in FIGS. 4A and 4B, in order to attach the holding mechanism 20 to the portable device 10 by the attaching / detaching screw 30, a recess 13 for screwing the attaching / detaching screw 30 is formed in the clip base 12. (A and B in FIGS. 2 and 4), and the back panel 11 of the portable device 10 is formed with a hole through which the recess 13 is passed. Therefore, the substrate 21 is attached to the clip base 12 by screwing the detachable screw 30 into the recess 13 in a state where the substrate 21 is superimposed on the clip base 12. At this time, by appropriately setting the length of the detachable screw 30 and the depth of the recess 13, the holding mechanism 20 can rotate relative to the clip base 12 even when the detachable screw 30 is screwed into the recess 13.

In this embodiment of the present invention, a click mechanism is provided so that the portable device 10 and the holding mechanism 20 are relatively rotated by a desired angle, for example, 90 degrees. That is, the clip base 12 fixed to the back panel 11 of the portable device 10 has four holes 14 ₁ , 14 ₂ , 14 ₃ , 90 ° apart from each other on the same circumference, as shown in FIG. 14 ₄ are formed, and shallow depressions 15 ₁ to 15 ₄ are formed in the back panel 11 corresponding to these holes 14 _{1 to} 14 ₄ . Incidentally, in FIG. 4, only the recesses 15 _2, one of these recesses is shown. Furthermore, the clip pin 28 is provided in the holding piece 22 of the holding mechanism 20, and a hole 16 is formed in the clip base 12 and a hole 29 is formed in the substrate 21 for passing the clip pin 28.

Therefore, as shown in FIG. 4B, when the lock lever 23 of the holding mechanism 20 is raised and the flat portion 27 of the lock lever 23 is brought into contact with the holding piece 22 to release the lock, the holding piece 22 is elastically deformed. away from the substrate 21, since the clip pin 28 be lifted from the back panel 11 is the leading end of the clip pin 28 in a state caught in one of the holes 14 ₁ to 14 ₄ of the clip base 12 accordingly, the portable device 10 can be easily removed from the object to be attached, and the holding mechanism 20 can be rotated with a click feeling with respect to the portable device 10. FIG. 5 shows a state in which the holding mechanism 20 is rotated by 90 degrees with respect to the portable device 10 from the state of FIG.

On the other hand, after the holding mechanism 20 is rotated by a desired angle with respect to the portable device 10 in the unlocked state shown in FIG. 4B, as shown in FIG. by pressing the clamping pieces 22, the lock lever 23 is locked, the leading end of the clip pin 29 enters the corresponding holes of the holes ₁₄ 1 to 14 ₄ of the clip base 12 through the holes 29,16. As a result, the portable device 10 is securely fixed to the holding mechanism 20 at a desired angle. As described above, one embodiment of the holding mechanism according to the present invention has been described, but the present invention is limited to this embodiment. Is not to be done. For example, although four holes 14 _{1 to} 14 ₄ are formed at 90 ° intervals in FIG. 2, holes may be formed at desired intervals such as 45 ° and 60 °. In the illustrated embodiment, the click mechanism is formed. However, the click mechanism need not be provided. In that case, the portable device 10 can be rotated by an arbitrary angle with respect to the holding mechanism 20.

As described above, the present invention is understood from the description of the holding mechanism according to one embodiment as an example.
By locking the holding mechanism, the portable device can be securely held.
By releasing the lock of the holding mechanism, the portable device can be easily detached from the attached object.
