Abstract

A pressurizing apparatus includes a lower frame and an upper frame. A first end of the upper frame may be hinged to the lower frame at a rotation axis, and a second end of the upper frame may be rotated about the rotation axis by an actuator. A pressurizing unit may be combined to the upper frame in such a way that the pressurizing unit is rotatable relative to the upper frame. When the actuator rotates the second end of the upper frame, the pressurizing unit pressurizes an object to be pressurized.

Claims

1. A pressurizing apparatus comprising:

a lower frame;

an upper frame including a first end hinged to a first end of the lower frame, at a first rotation axis, in which is defined a second groove at the first end thereof hinged to the first end of the lower frame;

an actuator connected to a second end of the upper frame and to a second end of the lower frame, the actuator comprising a driving motor mounted on the lower frame,

wherein the actuator pulls the second end of the upper frame towards the lower frame thereby rotating the second end of the upper frame about the first rotation axis and maintaining a distance between the second end of the upper frame and the first rotation axis and between the frame second ends opposite to the first ends thereof, respectively;

a pressurizing unit which is installed between the first end of the upper frame and the second end of the upper frame; and

a mounting unit connected to the lower frame, and mounting the lower frame to an object to be pressurized,

wherein

the object is pressurized by the pressurizing unit when the actuator rotates the second end of the upper frame toward the object,

the lower frame comprises;

a mounting part on which the actuator is mounted,

two arms which are parallel to each other and longitudinally extend from the mounting part,

a hinge shaft aligned with the first rotation axis, installed at distal ends of the two arms, inserted into the second groove of the upper frame, and

an opening having a rectangular shape formed by the mounting part, the two arms and the distal ends of the two arms, and

the upper frame is disposed inside the opening formed by the mounting part, the two arms and the distal ends of the two arms when the upper frame is pulled down by the actuator.

2. The pressurizing apparatus of claim 1,

wherein the pressurizing unit is installed to and rotatable relative to the upper frame about a second rotation axis which is different from the first rotation axis,

wherein the pressurizing unit pressurizes the object by contacting the object according to the rotation of the second end of the upper frame about the first rotation axis.

3. The pressurizing apparatus of claim 2, wherein the pressurizing unit is a fluid bag containing a fluid.

4. The pressurizing apparatus of claim 3, wherein the fluid bag comprises:

a body,

an upper fixing frame combined to an upper portion of the body,

a lower fixing frame combined to a lower portion of the body, and

a rotation shaft combined to the upper frame and aligned with the second rotation axis, such that the rotation shaft protrudes from each of opposing sides of the upper fixing frame, and the pressurizing unit is rotatable relative to the upper frame about the second rotation axis.

5. The pressurizing apparatus of claim 2, wherein the pressurizing unit is disposed inside the opening formed by the mounting part, the two arms and the distal ends of the two arms when the upper frame is pulled down by the actuator.

6. The pressurizing apparatus of claim 2, wherein the second rotation axis is disposed offset by a predetermined interval from a center axis of the pressurizing unit in a direction from the second end of the upper frame toward the first end of the upper frame.

7. The pressurizing apparatus of claim 2, wherein

a rotation shaft aligned with the second rotation axis is disposed protruding from each of opposing sides of the pressurizing unit, and

a first groove to which the rotation shaft is inserted, is disposed in the upper frame.

8. The pressurizing apparatus of claim 1, wherein a combining shaft which combines the mounting unit to the mounting part, is installed in the mounting part.

9. The pressurizing apparatus of claim 1, wherein a spring is installed between the lower frame and the upper frame, and the spring applies elasticity to the upper frame in a direction where the second end of the upper frame is distanced away from the lower frame.

10. The pressurizing apparatus of claim 1, wherein the actuator further comprises a string connecting the driving motor and the second end of the upper frame.

11. The pressurizing apparatus of claim 1, wherein the driving motor includes a pulley installed on a rotation shaft of the driving motor, and the string is wrapped around the pulley.

12. The pressurizing apparatus of claim 10, wherein the upper frame further includes supporting members disposed on the second end of the upper frame, and a first end of the string is fixed to the lower frame via the supporting members.

13. The pressurizing apparatus of claim 12, wherein the supporting members comprise two supporting rollers spaced apart from each other.

14. The pressurizing apparatus of claim 10, wherein the lower frame includes a guide roller which maintains a direction of the string.

15. The pressurizing apparatus of claim 1, wherein the mounting unit comprises:

a mounting band, wherein each of opposing ends of the mounting band are each connected to each of opposing ends of the lower frame, respectively, and

an adhesion unit disposed in a center of the mounting band, which connects distal ends of the mounting band to each other.

16. The pressurizing apparatus of claim 15, wherein the mounting unit further comprises a mounting frame surrounding at least a part of the object, and the lower frame is combined to the mounting frame.

17. The pressurizing apparatus of claim 1, wherein the actuator is connected to the second end of the upper frame at more than one location.

18. The pressurizing apparatus of claim 10, wherein the string is connected to the second end of the upper frame at more than one location.
