Abstract

PURPOSE:To impart a function which balances the load generated by a display section and a function to adjust its capacity to a mechanism for holding the display section in an information processor having the liquid crystal display section of an opening and closing type. CONSTITUTION:A thrust block 3 which is movable in an axial direction, a torque block 4 which is braked not to rotate and a spring 5 which presses the thrust block 3 and the torque block 4 are assembled to a shaft 2 rotatably held in a bracket 1. The torque block 4 is pressed to the thrust block 3 by screwing a collar 6 packaged via a bushing 7 mounted to this bracket 1 to generate initial torque in the shaft 2. A stopper 8 of the thrust block 3 and the pressing surface of the torque block 4 push and contract a spring 5 with rotation of the shaft 2 and generate the desired torque.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding mechanism for a liquid crystal display section of an information processing apparatus, and more particularly to a tilt unit capable of improving its operability and maintaining its function.

[0002]

2. Description of the Related Art In a conventional tilt unit, a holding capacity having a desired linearity is approximately generated by a combination of a plurality of springs or a combination of spring reaction force and tightening force. It will not be in balance.

Further, no consideration is given to changes with time such as wear.

[0004]

In the conventional tilt unit as described above, it is difficult to always generate a holding capacity in a balanced form with respect to a load having a non-linearity caused by the opening / closing angle of the liquid crystal display section. In addition, it is not possible to compensate for the deterioration of the holding capacity due to changes over time such as wear of the springs and components used.

[0005]

DISCLOSURE OF THE INVENTION The present invention relates to a tilt unit having a shaft for fixing a liquid crystal display unit attached to an information processing device so as to be openable and closable, and a load varying with an opening / closing angle of the liquid crystal display unit. It is characterized in that it is provided with means for generating a torque which always balances with the shaft.

According to the present invention, in a tilt unit having a shaft for fixing a liquid crystal display unit attached to an information processing device so that the liquid crystal display unit can be opened and closed, a sliding torque is always balanced with a load generated by the liquid crystal display unit. The present invention is characterized by comprising a coil spring incorporated so as to be generated in the shaft, and a mechanism for changing an initial pressing force and compensating for a sliding torque lost due to a change over time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of an embodiment of a tilt unit according to the present invention.

The bracket 1 is a part that serves as a base for assembling the tilt unit, and is formed so as to be fixed to a main body (not shown) of an information processing apparatus having an openable liquid crystal display (not shown). .

When the shaft 2 is fixed to the liquid crystal display unit and mounted on the bracket 1, the liquid crystal display unit is held in the main body in an openable and closable state.

The thrust block 3, the torque block 4, and the spring 5 are incorporated in the bracket 1 through the shaft 2.

The collar 6 is screwed into a bush 7 inserted in the bracket 1, and a detent 8 is provided to prevent the torque block 4 from rotating.

The thrust block 3 is attached to the shaft 2 in a state in which it can move in the axial direction and cannot rotate in the axial direction through a mechanism for inhibiting rotation, and is constantly pressed against the torque block 4 by a spring 5.

Although the torque block 4 is prevented from rotating by a detent 8, it can be moved in the axial direction and the collar 6
By screwing in, the mounting position after assembly can be adjusted freely within a certain range.

The collar 6 is provided with a screw portion that meshes with the bush 7, and is further provided with a groove for rotating with a driver or a coin, and is mounted so that its surface can be exposed to the outside of the main body of the apparatus. The position of the collar 6 can be adjusted even after completion of the assembly.

With such a structure, the initial position of the torque block 4 can be freely adjusted, and a desired initial torque can be obtained for the load to be supported by the tilt unit.

The bush 7 is assembled in a non-rotatable state such as being press-fitted from the inside of the bracket 1, and a screw portion that meshes with the collar 6 is provided inside the bush 7.

2 (a) and 2 (b) are perspective views showing the shapes of the thrust block 3 and the torque block 4, respectively. Both are coaxially mounted via the shaft 2 and are pressed against each other by the spring 5 to generate a friction torque.

The thrust block 3 side is provided with a pressing surface 9 protruding in a conical shape, and the torque block 4 is provided with a sliding surface 10 inclined in the circumferential direction.

The sliding surface 10 is formed in such a shape that the thrust block 3 can be pushed away in order to compress the spring 5 according to the weight of the liquid crystal display section that the tilt unit must hold.

The position of the thrust block 3 with respect to the torque block 4 changes in the axial direction as the pressing surface 9 slides on the sliding surface 10 in accordance with the rotation of the thrust block 3 accompanying the rotation of the shaft 2. However, as a result, a supporting torque is generated that is always balanced with the load having the non-linearity generated as the liquid crystal display unit rotates.

It is expected that the pressing surface 9 and the sliding surface 10 will be worn due to long-term sliding, and the contraction margin of the spring 5 will be shortened accordingly, so that a predetermined torque cannot be generated. Insufficient torque can be compensated for by changing the position of the torque block 4.

[0023]

As described above, according to the present invention,
Using a spring that can generate only a linear reaction force, it is possible not only to generate a supporting force that is always balanced against a load having non-linearity, but also to freely adjust the supporting force to further reduce the supporting force due to changes over time. It becomes possible to make up for it. As a result, in addition to always providing comfortable operability to the user of the device, it is possible to obtain the effect that parts can be shared by a plurality of types of devices.
