When the compression spring is in the closed state of the laterally open door in the increased state, the compression spring is located closer to the door side than the axis horizontal line connecting the shaft pin and the arm shaft, and pivotally hinged to the opening edge of the other side plate. When the door is opened, which is in the initial state of opening the door, the compression spring is compressed and the front pivot point is shifted to the axis horizontal line, and the arm is moved from the subsequent door opening state. Until the door and the pivot arm are held in a straight line and the door is completely opened, the compression spring increases, and the pivot point moves to a position closer to the side opposite to the door than the horizontal line of the axis. It is intended to provide a door opening / closing damper characterized by being selected to go.

When the door is closed as shown in FIG. 3, the pivot point P between the link arm 6 and the pivot base 7b of the pivot arm 7 by the pivot pin 6b is set.
The position is such that the arm 7c and the pivot arm 8 are bent,
In addition, on the premise that the compression spring 4 is in an extended state, a vertical axis line L connecting the shaft pin 6a and the arm shaft 7a.
It is selected to be closer to the door than ₁ . That is, the compression spring 4 moves the spring holding traveling body 5,
Push up in the attachment case 3 to move the pivot arm 8
Is turned and bent around the pivot pin 7d toward the door 1f of the arm portion 7c, and the pivot pin 6b
, This time, since it is positioned on the door side of Jikushintate Mukosen L _1, the restoring force based on the compression spring 4 with respect to the rotation base 7b, rotational force of the arrow R ₁ direction is transmitted, As a result, the door 1f is pulled toward the opening 1c via the pivot arm 8, and the door 1 door state is secured.

₁ gradually increases, and the link arm 6 moves the spring holding traveling body 5 downward, whereby the compression spring 4 is compressed and contracted. As the door 1f opens, the restoring force of the compression spring increases. The door 1f rotates and descends toward the door-opening completed state in FIG. 1B while receiving the braking force.

When the bending angle θ ₁ becomes 180 °, the pivot arm 8 hits the folded edge 7e ′ of the arm 7c,
As a result, the arm portion 7c and the pivot arm 8 are held in a straight line, and the lower plate 1b and the door 1f of the door attachment 1a are brought into a straight line. At this time, in the present invention, the pivot point P
It is a rotating drop, to transition to the substantially the axis Kokorotate Mukosen L _1, its position is selected. Therefore, in the door-opening completed state, the compression spring 4 is sufficiently compressed and compressed, and the rotating force by the restoring force of the compression spring 4 is applied to the rotating base 7b via the pivot pin 6b. However, since the transmission is not substantially transmitted, the door 1f can maintain the substantially horizontal door opening state without receiving an excessive force.

不要となる。Next, a damper for a lower opening door according to a second aspect will be described. In this case, the arm shaft 7a is provided in the mounting case 3 as shown in FIG. In addition, a configuration is added in which the rotating shaft 10a of the damper mechanism 10 having a braking force by viscous fluid in each direction of opening and closing the door 1f is connected to the arm shaft 7a. At this time, if the damper mechanism 10 exerts a braking force only when the door is opened by a one-way clutch (not shown) or the like, the braking force acting in the door-opening state makes it possible to provide a better braking force than in the first embodiment. In addition, the door can be opened more slowly and smoothly. Of course, the braking force of the damper mechanism 10 may be exerted both when the door is closed and when the door is opened. In this case, when the door is closed, the restoring force of the compression spring 4 which assists the above-described control is reduced. Although it is suppressed by the power, it is only necessary to adjust so that the assisting force for opening the door as a whole becomes large. Needless to say, in this case, the one-way clutch as described above becomes unnecessary.

P is to be transferred onto the axis vertical Mukosen L _1. Accordingly, this is the state of the conceivable point, the door 1f is closed and the door is not opened, and no turning force acts on the door 1f.
Until c and the pivot arm 8 are held in a linear state as described above and the door is completely opened, the compression spring 4 increases and the position of the front pivot point P is also than the axis vertical Mukosen L ₁ of, from going to transition to the anti-door side closer,
The rotation force in the opening direction is transmitted to the rotating arm 7, and the door opening completion state is maintained.

However, as shown in FIG. 7, the attachment case is fixed to the inner wall of one or both of the top plate and the lower plate 1b, and the spring holding traveling body 5 pressed by the compression spring 4 moves in the direction of the one side plate 1h. And of course, the pivot arm 8 is the door 1
It will be pivotally connected to the washer 9 of f. In the closed state as shown in FIG. 7, although the arm portion 7c and the pivot arm 8 are in a bent state, the compression spring 4 is in the extended state, and the spring holding traveling body 5 shifts to the side plate 1h. Yes,
Position of the pivot point P of the rotation base 7b of the link arm 6 and the pivot arm 7 by the siren pivot pin 6b has to exist on the door side nearer the axis vertical Mukosen L ₁ of the former opinion.

It will be transferred to the TateMukosen L _1. For this reason, this is a state of a conceivable point, and if the door is opened until it passes, from the subsequent door opening state, as disclosed in FIG. until a state reached door opening completion state, and length increasing compression spring 4 gradually, the position of the pivot point P, but this also the the axial center longitudinal Mukosen L ₁ of, transition counter-door side nearer Go. As a result, the rotating force in the direction of opening the door is transmitted to the rotating arm 7, and the opened state is maintained.
It is preferable that the door 1f is opened at a wide angle of 90 ° or more from the closed state.

In relation to the axis horizontal line, when the door is closed and when the door is opened, it is appropriately shifted, so that the door holding function, the door holding function, and the slow closing movement in the upper lid opening door are claimed. As in the case of 1, it can be guaranteed.
In the fourth aspect, the damper mechanism is appropriately incorporated in the third aspect, so that the effect of the third aspect can be further promoted.

Therefore, the compression springs were extended and contracted respectively, so by adopting this as the upper opening door, it was possible to set the door closing retention function and set the conceivable points in the initial state of opening the door, and to open the door later. Automatic opening of the door by the compression spring from the door state to the completion state of the opening and the holding of the open door are also possible, and further, the closing movement can be slowly lowered. In the sixth aspect, the damper mechanism is appropriately incorporated in the fifth aspect, so that the various effects according to the fifth aspect can be further promoted.

Since it is fixed to a plate and the position of the connection between the pivot point and the lateral line of the axial center is appropriately selected and configured, this is adopted for the side-opening door, and substantially in the case of claim 5 described above. The same effect as described above can be exhibited. And Claim 8
According to the seventh aspect, since the damper mechanism is appropriately added to the seventh aspect, the effect of the seventh aspect can be further promoted.
