Abstract

PURPOSE:To obtain the title device in such a way that it automatically opens to a prescribed angle and it can be stably held at any angle beyond this angle by installing a torque spring for automatic opening between a hinge shaft control pin and a bracket and further installing a slider, which conducts limited sliding movement, between the pin and the spring. CONSTITUTION:When an opening/closing body 3 is opened to an angle of about 20 deg. after locking devices 6 and 6 are released, automatic opening action of the opening/closing body 3 is completed because the upper step part 16b of a slider 16 abuts on a stopper pin 11a in order to prevent a hinge shaft 8 from rotating clockwise at a lower step part 16a. Nevertheless, since the torque of a spring 15 acts in the opening direction of the opening/closing body 3, the body 3 is held as it is. When the opening/closing body 3 is opened further, the body 3 can be opened, because a friction plate 11, which rotates by about 20 deg. together with the shaft 8, does not rotate any longer together with the shaft 8, while only the shaft 8 rotates together with the opening/closing body 3. In this case, since only the friction force between the plate 11 and the shaft 8 acts on the body 3, the body 3 can be stably stopped at any place and held there as it is.

(Function) When the locking device of the opening/closing body is released, the hinge shaft, which is biased in the - direction by the spring via the slider and control pin, automatically rotates to open the opening/closing body, but at a certain opening angle. When it reaches this point, the sliding movement of the slider is regulated and stops, and the rotation of the flexible plate is also regulated. Therefore, when an attempt is made to open the opening/closing body further, the opening/closing body is opened by the rotation of the hinge shaft fixed to the opening/closing body, but at that time, frictional force moves between the friction plate and the hinge shaft 1. The opening/closing body can be opened to maintain a stable stop 11 at any opening angle, and this function of holding the opening/closing body works equally in either opening/closing direction of the opening/closing body due to the frictional force between the friction plate and the hinge shaft. It is something to do.

A torsion coil spring I5 having a torque capable of automatically opening the opening/closing body 3 is wound around the spring ring portion 7a of the bracket 7, and one end 15a of the torsion coil spring I5 is connected to the bracket 7, and the other end 15a is connected to the bracket 7. 5b is a slider 1 housed in the case body 10 so as to slide only within a certain width.
They are in contact with the ends of 6. This slider I6
As shown in FIG. 6, the dovetail has a lower step portion 16a that comes into contact with the compression pin 14, and a -F step portion +6b that comes into contact with the stopper pin Ila of the friction plate 1l. Now, when the opening/closing body 3 is in the closed state, as shown in FIG. 8, it is rotated clockwise.

Therefore, when the locking devices 6, 6 are released as shown in FIG. 1, the opening/closing body 3 is automatically opened by the rotational torque of the spring 5. At this time, since the slider 16 is being pushed by the other end 15b of the spring 15, the press-fit pin 14 is pushed through the lower step 16a, and the hinge shaft 8 is rotated clockwise.
Slide slightly to the left as shown in the figure. The opening/closing body 3 is approximately 2
When opened to 0°, the slider 16 as shown in FIG.
The lower step portion 16
Since the hinge shaft 8 cannot be rotated clockwise via the compression pin 14 at point a, the automatic opening operation of the opening/closing body 3 ends, but the rotational torque of the spring 15 causes the slider 16 and the compression pin 14 to rotate. Since the torque of the spring 15 acts on the hinge shaft 8 through the hinge shaft 8, the torque of the spring 15 acts in the opening direction of the opening/closing body 3, and the opening/closing body 3 is held without falling naturally.

From this state, when you open the opening/closing body 3 by placing your hand on the 1j; 1 part, about 2
Since the friction plate 11 rotated by 0° has its stopper pin lla in contact with the stopper wall 1roa provided on the case body 10, the friction plate 11 does not rotate together, and only the hinge shaft 8 moves together with the opening/closing body 3. As a result, the opening/closing body 3 is opened. At that time, the torque of the spring 15 does not act, and the friction plate 11 and pinge shaft 8
Since only the frictional force between the opening and closing body 3 acts, no matter where it is stopped, the opening/closing body 3 will stop stably. The state will be maintained. When the opening is opened approximately 140 degrees in this manner, the compression pin 14 rotating together with the hinge shaft 8 comes into contact with the stopper portion 10b and is stopped, as shown in No. 10. It doesn't happen.

Also when closing the opened opening/closing body 3,
・The 11th stopper pin Ila is pushed by the other end 15b of the spring 5 at the 10th step +5b of the slider 6.
Since it is fixed by the hinge shaft 8, it does not rotate with the hinge shaft 8, and the same frictional force as when opening is applied between the hinge shaft 8 and the hinge shaft 8, which has been rotating since the beginning, and the free stop is closed so that it can be stopped at any opening angle. , when the opening angle is 20°, the compression pin 14 is moved to the lower part 16 of the slider 16.
a and further suppresses the opening/closing body 3, thereby causing the slider 16 to slide to the right against the rotational torque of the spring 15 and be closed. When the opening/closing body 3 is completely closed, the engaging pieces 5, 5 are locked by the locking devices 6, 6, and the opening/closing body 3 is kept in the closed state.

(Effects) 1 - As explained in detail, according to this invention, the opening/closing body is automatically opened by the spring torque up to a certain opening angle, and beyond a certain opening angle, the spring torque does not act and the opening/closing body is opened only by the friction torque. Because it will be opened,
In addition to being able to hold the opening/closing body stably at a stop at various angles of use, the friction torque is obtained by the friction plate, so that the opening/closing body can be applied evenly to both opening and closing movements. It is possible to achieve the effect that friction acts and stable opening/closing operation can be performed.
