Abstract

PROBLEM TO BE SOLVED: To provide a stay device with a stopper mechanism, which can be installed and used even in a small space and cost of which on manufacture and assembly is reduced easily. SOLUTION: The stay device with the stopper mechanism is composed of a mounting plate 4 fixed onto a door 2 installed to a fixed frame body 1 by a hinge 3, a slender spring ring 6 in which a base end section is attached pivotally at the front end section of the mounting plate 4 by a first shaft bar 5 parallel with a hinge shaft 11, and a second shaft bar 7 fixed onto the side face of the fixed frame body 1 and inserted into an opening section 10 in the longitudinal direction of the spring ring 6, and an inward bent section 9, in which the width of the opening section 10 in the longitudinal direction is made narrower than the diameter of the second shaft bar 7, is formed at the front end section of the spring ring 6.

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 will be described below with reference to a reference symbol in the accompanying drawings. A plate 4; an elongated spring ring 6 whose base end is pivotally attached to a distal end of the mounting plate 4 by a first shaft 5 parallel to the hinge shaft 11, and is fixed to a side surface of the fixed frame 1,
A second axial rod 7 inserted into the longitudinal opening 10 of the spring ring 6, and an inward bend at the distal end of the spring ring 6 to reduce the width of the longitudinal opening 10 to be smaller than the diameter of the second axial rod 7. A part 9 is provided.

In the case where the door 2 is mounted on the fixed frame 1 by the hinge 3 in which the hinge shaft 11 is disposed horizontally, when the door 2 is in the closed state as shown in FIG. And the second shaft 7 is engaged with the upper part of the longitudinal opening 10. When the door 2 is opened and rotated about the hinge shaft 11 from this state, the mounting plate 4
The spring ring 6 and the second shaft 7 are pulled around the fulcrum, and the engagement point between the longitudinal opening 10 and the second shaft 7 moves sequentially downward. Immediately before the door 2 opens and rotates to a predetermined angle as shown in FIG. 2, the second shaft 7 climbs over the pair of inwardly bent portions 9, 9 while spreading.

When the door 2 is opened to a predetermined angle,
The second shaft 7 is located below the inward bent portions 9, 9, and the door 2 is properly positioned at the flipped open position by the engagement between the second shaft 7 and the inward bent portions 9, 9. Stopped and held. When closing the door 2, the door 2 may be pulled down by the operator's hand so that the second shaft 7 can move over the inwardly bent portions 9, 9. As a result, the door 2 rotates in the closing direction by its own weight, and the second shaft 7 and the longitudinal opening 10 are rotated.
Will move sequentially upward.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, a fixed-side blade 3a and a rotating-side blade 3b of a hinge 3 are fastened and fixed to a fixed frame 1 and a door 2 by two screws 12. The L-shaped mounting plate 4 in plan view is fastened and fixed to the door 2 by two screws 8, and the support plate of the first shaft 5 protrudes from the edge of the door 2. The spring ring 6 is made of a spring wire selected to withstand the weight load of the door 2, and has a longitudinal opening 10 formed between a pair of parallel straight portions. An annular bent portion is formed at the end of the linear portion, and the first shaft 5 is inserted through the annular portion, so that the spring ring 6 only rotates about the first shaft 5. Therefore, the spring ring 6 does not move up and down with respect to the first shaft 5.

[0009]

The stay device with the stopper mechanism of the present invention configured as described above can stop and hold the door accurately at a predetermined open position, and has no bulkiness in the stopper mechanism portion and has an overall shape. Since the structure is simplified, 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.
