Description

  The present invention relates to an open / close door mechanism suspended by a tension spring and a portable device including the mechanism.

  Conventionally, most portable devices are driven by a battery such as a dry battery or a rechargeable battery. Therefore, a storage space for storing the battery is provided at an appropriate position of the portable device, and the storage space is covered with an openable / closable lid. (See Patent Document 1).

  However, the conventional mechanism for opening and closing the lid for battery replacement ensures that the lid is closed so that the lid does not open no matter what circumstances the portable device is used. There were many things that were not sufficient in terms of holding. For example, when a portable device is dropped, the lid opens due to the impact. In order to avoid this, if it is closed so tightly that a certain amount of force is required to open the lid, another problem arises that it is difficult for the elderly and children to open the lid.

In addition, many conventional lids have depressions or hooks that are used to open the lid by hooking the tip of your finger, creating irregularities on the surface of the device and making it feel neatly designed. Not given.

  As shown in FIGS. 4 and 6, a storage space 15 for storing the battery is formed on the surface 11 of the portable device 10, and the operation of the portable device 10 is set adjacent to the storage space 15. An operation setting unit 16 is provided. An openable / closable door 21 is mounted so as to cover the storage space 15 and the operation setting unit 16. The open / close door 21 has a wide surface 21 ′ forming a part of the surface 11 and side surfaces 22 and 23 on both sides thereof.

  Locking pieces 24 and 25 are formed at the upper ends of the left and right side surfaces 22 and 23 of the open / close door 21, respectively. On the other hand, locking pins 26 and 27 are formed at positions corresponding to the locking pieces 24 and 25 on each side surface of the portable device 10, and as shown in FIG. 2, when the open / close door 21 is closed, the locking pieces 24 are formed. , 25 engage with the corresponding locking pins 26, 27, whereby the open / close door 21 is held in a state of covering the storage space 15 and the setting portion 16.

  A rotary shaft 28 is integrally formed at the lower end of the open / close door 21, and the rotary shaft 28 is rotatably supported by lower ends of slide pieces 29 and 30 provided on the left and right side surfaces of the portable device 10. As shown in FIG. 2, two elongated holes 31, 32 are formed at appropriate positions of the slide piece 29 provided on the right side surface, and the portable device extends through each of these holes 31, 32. Protrusions 33 and 34 are planted from 10 side surfaces. Thus, the movable distance of the slide pieces 29 and 30 is defined by the holes 31 and 32 and the protrusions 33 and 34.

  Further, the upper end of the slide piece 29 is connected to one end of a spring 35 that pulls the slide piece 29 upward, and the other end of the spring 35 is fixed to the side surface of the portable device 10. Therefore, the slide piece 29 is pulled toward the upper surface 13 of the portable device 10 by the spring 35. The slide piece 30 provided on the left side surface is also slidably supported by the same configuration and is pulled toward the upper surface 13 of the portable device 10 by the spring 36. As a result, the open / close door 21 coupled to the slide pieces 29 and 30 by the rotating shaft 28 is also drawn toward the upper surface 13, so that when the open / close door 21 is closed, the locking pieces 24 and 25 are the locking pins 26 and 25. 27 is maintained in the engaged state.

  Further, a guide spring 37 is provided along the right side surface of the portable device 10 to push the locking piece 24 in the direction to open the open / close door 21. Therefore, in order to open the open / close door 21, the upper part of the portable device 10 is held by one hand, and the slide pieces 29 and 30 on both sides are held against the springs 35 and 36 by the thumb and index finger of the other hand. When sliding toward the lower surface 17 of the mold device 10 within the allowable movement range defined by the holes 31, 32, the open / close door 21 is also moved parallel to the surface 11 of the portable device 10. 25 and the locking pins 26 and 27 are disengaged, the locking piece 24 is pushed up by the guide spring 37, and the open / close door 21 is lifted from the surface 11. Therefore, when the open / close door 21 is rotated around the rotation shaft 28, the open / close door 21 is held in the open state shown in FIGS. The maximum angle at which the open / close door 21 can open with respect to the portable device 10, that is, the opening angle α is, for example, 120 degrees.

  7A to 7C schematically show the configuration of a click mechanism for holding the open / close door 21 in an open state, and FIG. 7A is a cross section taken along line AA in FIG. FIG. 4B is a cross-sectional view taken along line BB. When the opening / closing door 21 is opened as described above, the opening / closing door 21 stops at a position opened α degrees. This is because when the open / close door 21 is opened to α degrees, the cam protrusion 38 provided on the rotary shaft 28 is formed on the lower surface 17 of the portable device 10 as shown in FIG. This is because the inclined cam 42 of the rotary shaft 28 is brought into contact with the catching margin 41 formed on the lower surface 11 as shown in FIG. In FIG. 7, reference numeral 18 is a dry battery serving as a power source for the portable device 10.

  With such a structure, while the door 21 is opened to α degrees, a force in the closing direction is applied to the door 21 by the action of the cam contact surface 39 and the springs 35 and 36. On the other hand, even when the open / close door 21 is opened beyond α degrees by an excessive force, the slide pieces 29 and 30 are further moved to the left against the springs 35 and 36 as shown in FIG. Since the cam 42 catches and gets over the allowance 41, it is possible to prevent the opening / closing door mechanism from being destroyed by an excessive force. That is, when the open / close door 21 is opened beyond α degrees, a component force is generated by the inclined cam 42 and the rotating shaft 28 is moved to the left. However, the stress is caused by the reaction force of the springs 35 and 36. Alleviated. Thus, the rotational stress applied to the rotary shaft 28 with respect to an excessive load is distributed to the springs 35 and 36, and the mechanism can be prevented from being broken.

So far, one embodiment of the opening / closing door mechanism according to the present invention has been described, but the present invention is not limited to this embodiment. For example,
(1) Although the opening / closing door has been described as covering a part of one surface of the portable device, the opening / closing door may have a size covering the entire surface.
(2) Although the locking piece is engaged with the locking pin to hold the open / close door in a closed state, the lock is performed by moving in one direction of the open / close door and moving in the other direction. Any mechanism can be adopted as long as the mechanism is unlocked.
(3) Although two holes are provided in each slide piece as shown in FIG. 2, the number of holes may be one, or three or more.
(4) As shown in FIG. 7, the example in which one cam projection is provided along the circumference of the rotation shaft has been described. However, a plurality of cam projections are provided along the circumference of the rotation shaft to open and close the door at a plurality of angles. You may make it stop.

As is clear from the above description, the present invention
(1) An open / close door mechanism that can be opened / closed by a simple operation while being able to reliably hold the open / close door in a closed state can be provided.
(2) When unnecessary pressure is applied to the open / closed door, it can be structured to release the force, and it can be opened or closed during the open / close state. Can prevent the door from being destroyed,
(3) Since a mechanism that does not open and close the door with a knob or the like is adopted, in a portable device equipped with such a door mechanism, even when the portable device is dropped, the door is not Will not open carelessly,
(4) Since the mechanism that locks the door in the closed state is not exposed to the outside, the degree of freedom in the design of the portable device is high.
