Abstract

PURPOSE:To facilitate the installing work of lid bodies while compacting the shaft device, and to eliminate the opening of an apparatus main body cabinet so as to prevent the invasion of foreign matters into the apparatus and to improve the appearance of the apparatus. CONSTITUTION:This shaft device is composed of the first lid body 14 furnishing the first shaft body, the second lid body 15, and shaft members 12 and 13 which hold the first and the second lid bodies rotatable. To the shaft members 12 and 13, a locking member 12a to be locked to an apparatus main body cabinet is provided, and a bearing to be abutted to the first shaft body is provided integrally so as to hold the first lid body 14 rotatable. Furthermore, the second shaft body is provided integrally to the shaft member so as to hold the second lid body 15 rotatable from both sides. As a result, by using only one shaft member for both sides, 12 and 13, the first lid body 14 and the second lid body 15 can be held rotatable, the shaft device part can be made compact, the distance between shafts between the first lid body 14 and the second lid body 15 can be reduced, a space necessary around the shafts is minimized, and the restriction of the shaft positions can also be improved extensively.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shaft device for rotatably holding a lid in various types of equipment.

0002

2. Description of the Related Art An example of a conventional shaft device will be described below with reference to the drawings.

FIGS. 7 and 8 show cross sections of a conventional shaft device, and FIG. 8 shows a cross section taken along line DD in FIG. In FIG. 7, 1 is a device main body cabinet, and 2 is a shaft member fixed to the main body cabinet 1. Reference numeral 3 denotes a first lid body, which has a rotating arm portion 3a, and a shaft hole 3b is provided in the rotating arm portion 3a.
By fitting the first lid body 3 into the shaft portion 1a of the
is held rotatably. Reference numeral 4 denotes a second lid body which is rotatably held on the shaft body 2a of the shaft member 2. The shaft device shown in FIG. 8 shows only one side, with the first and second
The lids 3, 4 are held from both sides by symmetrical shaft devices.

However, with the above configuration, it is difficult to attach the first lid 3 to the main body cabinet 1 because it is necessary to bend the rotating arm 3a. 1 requires an opening 1b through which the rotating arm 3a passes. Therefore, when the first lid body 3 is in the open and closed state, there are problems such as foreign objects entering the inside of the device through the opening 1b and defects in the appearance of the device such as the inside of the device being visible through the opening 1b. A space is required for the rotational movement of the first lid 3, and there is a large restriction in the axial position with the second lid 4 depending on the mutual rotation angle, and the shaft device requires a large space. there was.

The present invention solves the above-mentioned conventional problems, and makes the shaft device smaller, makes it easier to attach the lid, and eliminates openings in the equipment cabinet to prevent foreign matter from entering the equipment and improve the appearance of the equipment. It is an object of the present invention to provide a shaft device that also solves the above problems.

[0006]

[Means for Solving the Problems] In order to solve the above problems, the shaft device of the present invention includes a first lid body having a first shaft body, a second lid body, and first and second lid bodies. The shaft member rotatably holds the lid, and the shaft member has a locking part that locks onto the device main body cabinet. A bearing that abuts on the shaft member is integrally provided, and a second shaft body is integrally provided with the shaft member to rotatably hold the second lid body from both sides.

[0007]

[Operation] With the above-described structure, the present invention can rotatably hold the first and second lids with only one shaft member on each side, and the shaft device portion can be made small. The distance between the axes of the lid body can be reduced, the space required around the shaft is minimized, and the constraints on the shaft position are greatly improved. Further, the device main body cabinet does not require an opening, and the first and second lids can freely rotate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A shaft device according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an entire device having a shaft device according to an embodiment of the present invention. In FIG. 1, 11 is the main cabinet, 12 is the right shaft member, 1
Reference numeral 3 indicates a state in which the left shaft member 14 is opened with a first lid, 15 is a second lid, and 16 is a mounting screw. 2 shows a cross section taken along line AA in FIG. 1 of the shaft device according to the embodiment of the present invention, FIG. 3 shows a perspective view of the right shaft member 12, and FIG. 4 shows a cross section taken along line B-B in FIG. Figure 5 shows C in Figure 4.
It is an arrow view. In FIGS. 2 and 4, the right shaft member 12 is locked to the main body cabinet 11 by a locking claw 12a, and the main body cabinet is sufficiently fixed by a mounting screw 16 against the load acting on the right shaft member 12. 11 with screws. Furthermore, the right shaft member 12
The guide ribs 12c, 12d provided on the main body cabinet 11 fit into the guide grooves 11c, 11d provided on the main body cabinet 11. 14a is a first lid right shaft formed integrally with the first lid 14; The right bearing portion 12e is rotatably abutted on the right bearing portion 12e. 15a is a second lid right bearing part provided on the second lid, and the right shaft part 12 is integrally formed with the right shaft member 12.
