Abstract

This invention provides a door braking fixture capable of minimizing the variation of the braking force of a rotary damper, assuring a smooth closing operation of the door, and assisting the swing movement of the door and the braking of the door with an urging member. The fixture includes a rotary damper 11 containing a viscous fluid 14 which brakes the movement of the door 5 with a viscous resistance while door 5 swings in a vertical direction with respect to a supporting shaft 4 disposed horizontally. The rotary damper 11 contains a coil spring 16 having one end fixed onto a housing 12 and another end fixed onto a rotor 13, while the door 5 has a center of gravity G positioned on an approximately vertical line of the axis of the supporting shaft 4 in that state that the urgent force of the coil spring 16 is relieved.

Description

524936 V. Description of the invention (1) [Detailed description of the invention] [Technical field to which the invention belongs] The present invention relates to a brake mechanism, such as [known technology], used for door direction rotation of a door hinge of a printer or the like k. To prevent the rotation of the door that can be oriented horizontally, such as a printer, but also the direction of the glaze, it is wonderful and careful to control the product. When using six movements, use the f method that can be moved by the viscous method.杬 While the rotation-type corpse blocking T that is paid for the braking force, the body of the L body is stuck to the door. The braking structure of the cymbal is turned toward the direction of opening the cymbal, or: 5: the rotation of the two cymbals can be moved. Use the braking force. < 疋 σ Θ The direction of the lintel is turned, and when the center of gravity of the lintel is on the top, and the direction of closing the lintel is approximately perpendicular, the center of gravity will be opened by the lintel, and the rotation speed of the lintel will follow the lintel. As it turned, Yimen's lintel fell. Due to the quality of the door hinge, a proposal is made to set a 硿 yang 忒 in a rotating damper of a ^ m ^ m ^ type, and another bullet fixed to the rotor is pushed. Xia Zhi is fixed to an external product with a direction to open the door. The thrust energy f ^ is a braking structure that stores the door cymbal in the ejection member. The heart-shaped women's rotary damper's braking structure according to this door hinge is pushed by the spring direction in the direction of the door. Therefore, when the door ^ push member is closed and the lock mechanism for opening the door is released, the lock member ^ is pushed and the lock is locked. The viscous resistance of the fluid that is fixed at this position is prevented, but although the thrust force will be affected by the viscosity, the &

313632.ptd clarified that (2, the thrust is opened. Moreover, the door & to push and push 1 [invented to solve the problem, however, the opening of the opening of the door lintel 'makes the door lintel: the center of gravity will be faster because it will act on the door lintel In addition, it is necessary to resist the poor pushability. 扉 is therefore unable to determine the center of the door in the latter case, because the door is turned to close the door member for the spring push the door】] when the door over supports When the door is moved and the door is moved, the elastic thrust of the elastic thrust member rotates toward the opening and closing directions. The braking structure moves when the lock is released from the vertical line of the axis of the elastic thrust shaft of the elastic thrust member. The rotation speed of the bomb of the pusher member will be lowered due to the quality of the lintel. In order to accumulate bombs in the pusher member to rotate the lintel, the present invention is directed to solve the above problems, and its purpose is to provide a rotary damper that can be reduced. The braking force changes, and the door is closed well, and the door hinge can be assisted by the ejection mechanism. Structure [Method for solving the problem] The brake structure of the lintel of the present invention is to prevent the lintel of the lintel from rotating toward the horizontally arranged support shaft by the viscous resistance of the internal fluid of the rotary damper. In a state where the axis of the center of gravity of the lintel is substantially perpendicular to the axis, one end of the elastic pushing force of the elastic pushing member is fixed to the housing of the machine having the lintel, and the other end of the pushing member is fixed to the lintel, or Rotary damper with internal mechanism and slamming door thrust rotation force, operated in the lifting action and its sticking set perpendicular to the support will be set

The speed change is reduced, and the door and the part can be maintained to rotate y. When y is closed, the door lintel is turned 5 counterclockwise from the state shown in Figure 4-& M: Closed (= Jing 16 has no accumulated thrust) In the state where the door is closed and the bomb is closed, 'accumulated in the coil bomb = moreover', the door 扉 5 can be closed with good operability. Figure 夂 State Step Ϊ When the door 扉 5 is opened, or from the fourth position. The historical monument of the moving door screen 5 is turned clockwise and turned away from the car as shown in Figure 4. In the case of the spring thrust accumulated in the coil spring 16, the spring thrust of the two coil springs 16 can assist The rotation of the lintel 5. Because the lintel 5 'rotates in the direction of the needle from the state shown in FIG. Turn and re-open the door lintel 5, and the brake accumulator thrust of 15 is combined. Therefore, the coil spring 16 can be used to assist the two doors and the lintel. The implementation form does not show a card with a locking recess 2b and a recess 2b in each case 2 The example of "stop recess", but a plurality of lock recesses can also be set at M 5C, and I can be selected arbitrarily from the plurality of lock recesses 2b, 5c. The weight of the shape is about the axis of the support shaft 4 On the vertical line, the spring thrust of the coil spring 16 is released. Furthermore, it is shown that the coil spring 16 is installed in the rotary damper.
