Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stay with a stopper mechanism which is used for opening and rotating a door or a cover plate with respect to a fixed frame such as a box body and then stopping and holding the door or cover at a required open position. It concerns the device.

[0002]

2. Description of the Related Art A stay device with a stop lever disclosed in Japanese Utility Model Registration No. 3040884 has a fixed band plate fixed to a fixed frame, and one end of a movable band plate is pivotally attached to a door and fixed. The sliding plate is mounted on the front side of the fixed band plate by the first shaft bar and the second shaft bar inserted into the guide groove of the band plate, and the stop lever is pivotally connected to the first shaft bar, and the second shaft is The movable band plate is connected to the slide plate by a rod, and a stop washer is fitted to the first shaft bar between the stop lever and the slide plate. The shaft bar connected to the stop lever and the movable band plate are connected to each other. Since the connecting shaft rods are completely separated, even if the movable band plate is rattled, the play does not directly affect the tightening of the sliding plate by the stop lever and the stop washer, and the movable band plate is movable. The strip can be firmly stopped and held at a required position.

[0003] However, this conventional device is relatively uncomfortable because of its relatively complicated shape and structure, and its bulky stop lever mechanism makes it unsuitable for use in small spaces and has a large number of components. In addition, the cost of manufacturing and assembling increases.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a stopper mechanism having a small bulk so that it can be mounted and used even in a small space, and to reduce the cost of manufacturing and assembling since the number of components is small. Is to provide a stay device with a stopper mechanism which is easy to perform.

[0005]

A stay device with a stopper mechanism according to the present invention includes a mounting plate 4 fixed to a door 2 and a hinge shaft 12 parallel to a hinge shaft 12. The proximal end is pivotally attached to the distal end of the mounting plate 4 by the first shaft 6, and the guide groove 1 is moved from the proximal end toward the distal end.
0; a second axial rod 7 fixed to the fixed frame 1 and fitted to the guide groove 10 so as to be relatively movable; and a movable strip 5 close to the tip of the guide groove 10. And a pair of corrugated arms 9b and 9c, which are fitted with the third curved portion 9a on the third curved portion 8 and are engaged with and disengaged from the side portions of the second curved portion 7. The clip spring 9 is extended so as to overlap the tip of the groove 10.

In the case where the door 2 is mounted on the fixed frame 1 by the hinge 3 in which the hinge shaft 12 is disposed horizontally, when the door 2 is in the closed state as shown in FIGS. Reference numeral 5 is disposed substantially vertically, and the second shaft 7 is engaged with the base end of the guide groove 10. When the door 2 is opened and rotated from this state, the movable strip 5 pulled by the mounting plate 4 is lifted obliquely while rotating around the first shaft 6. In this process, the point of engagement between the second shaft 7 and the guide groove 10 moves toward the distal end, and when the door 2 opens and rotates to a predetermined angle as shown in FIGS. The bar 7 is engaged with the pair of corrugated arms 9b and 9c of the clip spring 9 so as to be held from both sides.

Therefore, the door 2 automatically stops at the open position, and is stably held at the stop position by the elastic force of the clip spring 9 selected to withstand the weight load of the door 2. When the door 2 is pulled down and rotated in the closing direction, the second shaft 7 is automatically disengaged from the waveform arms 9b and 9c of the clip spring 9 at the initial stage of the rotation. Then, as the closing rotation of the door 2 progresses, the engagement point between the second shaft 7 and the guide groove 10 moves from the distal end toward the proximal end.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, a fixed-side wing plate 3a and a rotating-side wing plate 3b of a hinge 3 are fastened and fixed to a fixed frame 1 and a door 2 by two screws 13. The mounting plate 4 is fastened and fixed to the door 2 by two screws 14. The movable strip 5 has a wave arm 9 of a clip spring 9.
b, 9c, a pair of spring holding plate portions 1 that abut against the outer crests
1, 11 are protruded. The opening angles of the corrugated arms 9b, 9c are regulated by the spring holding plates 11, 11,
Initially, the interval g between the inner wave fronts of the wave arm portions 9b and 9c is set to be smaller than the width of the guide groove 10.
Therefore, the second shaft 7 is held sufficiently firmly by the clip spring 9.

[0009]

As described above, the stay device with the stopper mechanism according to the present invention can accurately stop and hold the door at the predetermined open position, and has no bulkiness in the stopper mechanism portion, thereby simplifying the overall shape and structure. Because of this, it can be mounted and used even in a small space, and since the number of components is reduced, the cost of manufacturing and assembling can be easily reduced.
