DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device housing for a portable terminal device (HHT) or the like, and more particularly, to a locking device for a rotary lid for storing and fixing a battery in the device. .

[0002]

2. Description of the Related Art FIG. 18 is a view for explaining a conventional opening / closing structure of a rotating lid. As shown in FIG. It comprises a face plate 33 and a bottom plate 34. An opening is provided in the device housing 31 on one side of the side plate 33 (side surface).
A battery housing 36 for housing the battery 35 is provided inside the opening. A battery cover 37 as a rotating lid for covering the opening is provided in the opening.
Is attached. The battery cover 37 is formed of a plate, and a shaft hole 38 is formed at an upper end of the plate. On the other hand, a pair of inner walls (the inner wall 40 and the inner wall opposed thereto) of the recess 39 of the surface plate 32 are provided in the recess 39 of the surface plate 32.
Are provided with supporting shafts (not shown) at positions corresponding to the rotating shaft holes 38. By inserting the supporting shafts into the shaft holes 38, the battery cover 37 is rotatable. It is supported by the body 31. In addition, the battery cover 3

SUMMARY OF THE INVENTION A lock device according to the present invention comprises:
As shown in claim 1, a box body 1 having a housing recess 5 for housing a battery 12 therein, and an opening 7 provided in the box body 1 to allow the battery 12 to be inserted into and removed from the housing recess 5. A rotatable lid 9 rotatably provided around one end so as to open and close the opening 7. The rotatable lid 9 is provided in the vicinity of the rotatable lid 9. In order to prevent the pivoting lid 9 from pivoting in the opening direction, the pivoting lid 9
The lock is movable between a first position in which the rotary lid 9 is locked in a closed state by contacting with the first position and a second position in which the rotary cover 9 is rotated by releasing the contact. Members 10, 19,
27 is provided.

According to such a configuration, if the rotating lid 9 is closed while the battery 12 is housed in the housing recess 5 of the portable device and the lock members 10, 19, 27 are moved to the first position, The lock member comes into contact with the rotating lid 9, and the rotating lid 9 is locked in the closed state. In this state,
For example, even if a shock or the like is applied to the box 1 of the portable device from the outside and the battery 12 tries to jump out, the battery 12 is still locked because the rotating lid 9 is securely locked by the lock members 10, 19, and 27. It is possible to avoid a situation in which the housing is kept housed in the housing recess 5 and jumps out. On the other hand, when the lock members 10, 19, and 27 are moved to the second position, the contact state with the rotating lid 9 is released, so that the rotating lid 9 is opened and the battery 12 inside is taken out. Becomes possible.

[0008] The above-mentioned object can be similarly solved by a rotating lid reinforcing device according to the present invention. The reinforcing device includes a box body 1 having a housing recess 5 for housing a battery 12 therein, an opening 7 provided in the box body 1 to allow the battery 12 to enter and leave the housing recess 5, And a rotating lid 9 rotatably provided around one end so as to open and close the opening 7. The rotating lid 9 is connected to the box 1 continuously from the recess 8. A sliding groove 23 that is provided and penetrates into the housing recess 5, and a sliding piece 23 slidably guided by the through groove 26 in a direction parallel to the rotation center axis of the rotating lid 9. A reinforcing plate 25 provided integrally with the sliding piece 23 and protruding into the accommodation recess 5 through the through groove 26.
A first position where the reinforcing plate 25 contacts the battery 12 to prevent the battery 12 from escaping from the housing recess 5, and a position where the reinforcing plate 25 contacts the battery 12. A second position allowing the battery 12 to escape from the housing recess 5 can be taken.

According to such a configuration, when the rotating lid 9 is closed while the battery 12 is housed in the housing recess 5 of the portable device and the sliding piece 23 is moved to the first position, this sliding The reinforcing plate 25 provided integrally with the piece 23 comes into contact with the rotating lid 9, so that the battery 12 is prevented from coming out of the housing recess 5. In this state, for example, the box 1 of the portable device
Even if the battery 12 jumps out due to an external impact or the like, the movement of the battery 12 to escape is reliably prevented by the reinforcing plate 25.
The battery 12 is still housed in the housing recess 5 without the abutment of the battery 2 on the rotating lid 9, and a situation in which the battery 12 jumps out is avoided. On the other hand, when the sliding piece 23 is moved to the second position, the contact state of the reinforcing plate 25 with the battery 12 is released, so that the rotating lid 9 is opened and the middle battery 12 can be taken out. It becomes possible.

Further, as shown in FIG. 2B, a through-hole 2 having a T-shaped cross section for inserting the sliding piece 23 in parallel with the battery cover 9 is formed in the surface plate 2.
6 are formed. The through-hole 26 thus formed
When the sliding piece 23 is inserted into the opening 7 and the sliding piece 23 is moved toward the inside of the opening 7 so as to approach each other, both sides of the opening 7 are closed by the sliding piece 23. It is possible to prevent the user from falling out of the storage section 5. Further, as shown in FIG. 3C, the respective sliding pieces 23 are moved away from each other (arrows A and B).
When the battery cover 9 is opened as shown by the arrow C and the battery 12 is opened and retracted in the battery accommodating section 5 in the direction of the arrow D, the battery 12 can be freely retracted.

The projection 24a formed on the surface of the upper portion 24 of the sliding piece 23 prevents sliding of the fingertip when sliding the sliding piece 23. FIG. 17 shows a main part configuration of a ninth embodiment of the present invention. In FIG.
The sliding piece 27 is formed in a substantially L-shape. In addition, a reinforcing plate 29 which is continuous with the upper portion 28, hangs down at a right angle to the upper portion 28, and is formed in a fan shape so that the lower side is narrower than the upper side is integrally provided at the lower portion. ing. In addition, as shown in FIG.
A through hole 30 having a T-shaped cross section for inserting the sliding piece 27 in parallel with the battery cover 9 is formed. When the sliding piece 27 is inserted into the through hole 30 formed as described above, and the sliding piece 27 is moved closer to the inside of the opening 7, both sides of the opening 7 are closed. 12 can be prevented from falling out of the battery housing 5. Further, in this state, when an impact force or the like is applied to the apparatus housing 1 from the outside, the battery cover 9 tends to rotate around the support shafts 11a. However,
In this case, one side of the upper portion of the through hole 30 is in contact with a portion continuous with the concave portion 8 of the surface plate 2, so that the upper portion 28 of the sliding piece 27 is moved from the opposite side of the support shafts 11a, 11a to the impact force. Can be prevented from opening because the battery cover 9 is pushed in the direction to cancel the. further,
As shown in FIG. 3C, the opening 7 is set so that the respective sliding pieces 27 are away from each other (in the directions of arrows E and F).
When the battery cover 9 is opened in the direction of arrow G while the battery 12 is slid outward, the battery 12 can be made to be freely retractable and retractable in the direction of arrow H.

[0025]

According to the present invention, even when an external impact is applied, the battery cover as the rotating cover does not open, so that damage to the locking claws of the battery cover can be prevented, and the structure can be improved. Thus, an excellent housing structure can be obtained. Further, since the battery does not come off from the apparatus housing, the backup of the battery is completed, and the reliability of the data stored in the memory is improved. Furthermore, the packing provided in the battery lock improves the confidentiality of the device housing, so that a portable terminal device having an excellent drip-proof structure can be provided.
