DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for assembling two housings for housing electronic equipment such as a personal computer and a word processor. The present invention relates to a tilt unit capable of easily mounting two housings.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
Holes 1a, 1b and 2a, 2b between
, And the tilt unit 13 and the support component 14 are inserted and assembled into each of them. FIG. 5 is a perspective view showing the external structure after assembly. The first housing 1 and the second housing 2 assembled in this manner have a structure that opens and closes in the direction of the arrow with the tilt unit 13 and the support component 14 as fulcrums.

The assembling procedure is as follows. First, as shown in FIG. 5, the housing 1 and the second housing 2 are joined at hinge portions A and B (), and the support component 14 is screwed to the second housing 2. Attachment () from the inside of the body 2, the hinge part A determines one position of the open / close fulcrum of the first housing 1 and the second housing 2,
Then, the tilt unit 13 is attached from the inside of the second housing 2 with the screw 16 (), and the hinge portion B determines another position of the opening and closing fulcrum of the first and second housings 1 and 2. Was done by.

[0004]

In such a conventional tilt unit, when connecting two housings, it is necessary to match the mounting positions of the two housings, and while maintaining the aligned state. Since the two housings must be turned upside down and the tilt unit must be mounted from the inside of the second housing 2, many work steps are required.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a tilt unit capable of combining two housings in a short time with simple work contents.

[0006]

According to the present invention, there is provided a cylindrical shaft having a connecting portion which is inserted into a connecting hole of a first housing and a second housing for accommodating a component and is openably and closably connected. A tilt unit including a body and a tilt spring that is disposed in a state of being wound around the outer periphery of the cylindrical shaft and biases the first casing and the second casing to open. When the connecting portion of the shaft is inserted into the connecting hole of the second housing, the end surface is formed so as to be substantially flush with the surface of the second housing, and the shaft center of the shaft is formed. Is provided with a cylindrical hole having a predetermined depth, a compression spring and a substantially shell-shaped sliding surface formed at the tip of the cylindrical hole, and the sliding surface
When the end of the first housing abuts, the end of the first housing
A movable member that is pushed into the cylindrical hole while sliding with the portion to compress the compression spring and is pushed out by the compression spring when the compression spring matches the connection hole of the first housing. It is characterized by.

[0007]

When the end of the first housing is inserted into the connecting hole of the second housing and is pushed into contact with the sliding surface at the tip of the movable member protruding from the end surface, the first housing is pushed in. To power
The movable member is moved so as to be pushed into the cylindrical hole of the connecting portion. At this time, the compression spring is in a compressed state, and when the first housing moves and the connection hole reaches the position of the movable member, the movable member is pushed out by the compression spring, inserted into the connection hole, and inserted into the first housing. The body and the second housing are connected.

[0008] As described above, since the first housing and the second housing can be connected to each other by the support parts and the tilt unit constituting the hinge, the first housing and the second housing can be inverted.
Work while maintaining the positioning state can be eliminated,
Therefore, the work is simplified, and the number of work steps can be significantly reduced.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing a main part of the configuration of the embodiment of the present invention, and FIG. 2 is a perspective view showing an external shape of the embodiment of the present invention.

The embodiment of the present invention is directed to a cylindrical case having a connecting portion which is inserted into connecting holes 1a and 2a of a first housing 1 and a second housing 2 for accommodating the components and which is openably and closably connected. A shaft body 3 and a tilt spring 6 which is arranged in a state of being wound around the outer periphery of the cylindrical shaft body 3 and urges the first housing 1 and the second housing 2 to open. Further, as a feature of the present invention, when the connecting portion of the shaft body 3 is inserted into the connecting hole 2a of the second housing 2, the end face 3a of the second housing 2
A cylindrical hole 3b having a predetermined depth is provided in the axis of the shaft body, and a compression spring 4 and a sliding surface 5a at the tip are formed in the cylindrical hole 3b. The movable member 5 which is formed and compressed by the compression spring 4 when the end portion 1c of the first housing 1 abuts on the connection hole 1a of the first housing 1 is compressed by the compression spring 4. Is installed internally.

When assembling the first housing 1 and the second housing 2 using the tilt unit configured as described above, first, the tilt unit and the support are connected to the connection holes 2a and 2b of the second housing 2. The components are inserted in advance, and when the first housing 1 is mounted, the connection holes 1b are aligned with the support components already inserted in the second housing 2 and inserted.

When the first housing 1 is fitted to the second housing 2, the first housing 1 moves in the direction of the arrow as shown in FIG. It comes into contact with the sliding surface 5a of the movable member 5 projecting from the connection hole 2a of the body 2. When the movable member 5 further moves, a pressing force is applied to the sliding surface 5a of the movable member 5 by the end portion 1c, and the component force pushes the movable member 5 into the cylindrical hole 3b.

As the movable member 5 moves, the compression spring 4 is in a compressed state, and the first housing 1 further moves to move the movable member 5.
When the connecting hole 1a reaches the position (1), the compression spring 4 expands and the movable member 5 is inserted into the connecting hole 1a of the first housing 1.

By such an operation, the first housing 1 and the second housing 2 are connected by the supporting parts and the tilt unit at the hinge portions A and B shown in FIG. Thus, when turning over to screw the support component and the tilt unit, it is possible to eliminate the work while maintaining the aligned state.

[0015]

As described above, according to the present invention, when connecting two housings, it is not necessary to align the connection holes of the respective housings, and therefore, the alignment is maintained. However, it is possible to eliminate the operation of inverting the two housings, thereby simplifying the operation and reducing the number of operation steps.
