Abstract

PURPOSE:To simplify the opening and closing operation of a door by loading an inductor energized with a spring and having a semi-circular head to a stopper, and interlocking a recess of a bracket provided to a door with the inductor to stop the door in the case the door is opened. CONSTITUTION:An inductor energized with a spring 2 and having a spherical head is loaded to the inside of the basic shaft 1 of a door stop (stopper) 4 mounted on a wall W or a floor so that it is capable of coming in and out. While, a bracket 6 having a recess 5 with a diameter larger than a radius of curvature of the head of the inductor is provided to a door D. In the case the door D is opened to bring the bracket 6 into contact with the door stop 4, the inductor 3 is fitted to the recess 5 of the bracket 6 to stop, and in the case the door is closed, the interlock of the door D with the inductor 3 is released by turning the door D only in the closing direction. According to the constitution, a latch, etc., can be obviated to simplify the operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt stop mechanism for a door stop device.

[0002]

2. Description of the Related Art A conventional door stop device has a tilt stop mechanism.
The base end of a ring-shaped latch is pivotally supported on a base shaft standing on the floor or wall surface, and the tip of the latch is engaged with a hook-shaped receiver attached to the door. It was
And the operation of this latch was done by hand.

[0003]

As described above, in the conventional tilting mechanism of the door stop device, the latch has to be operated by one hand, which is a troublesome operation.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a tilting mechanism for a door stop device which does not require manual operation of a latch.

[0005]

Therefore, in the door stop device of the present invention, it is loosely fitted in the base shaft 1 so as to be slidable up and down, and is urged by the spring 2 so that the head protrudes from the base shaft 1. And a door stop 4 having a slider 3 and a receiver 6 having a recess 5 into which the head of the slider 3 can be fitted, on the side where the slider 3 protrudes. And

It is preferable that the head of the armature 3 is hemispherical. The recess 5 of the receiving tool 6 is preferably a concave surface having a radius of curvature larger than the radius of curvature of the head of the slider 3.

[0007]

When the door D is opened, the head of the slider 3 of the door stop 4 is fitted into the recess 5 of the receiving tool 6, and the door D is locked in the door stop 4.

When the door D is closed, the head of the slider 3 comes out of the recess 5 of the receiver 6, and the lock of the door D by the slider 3 and the recess 5 is released.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory view showing a usage state of a tilt stop mechanism of a door stop device of the present invention, and FIG. 2 is a sectional view of a tilt stop mechanism of the door stop device of the present invention.

The tilting mechanism of the door-stop device of the present invention is loosely fitted in the base shaft 1 so as to be slidable up and down, and the idler 3 is urged by the spring 2 so that the head projects from the base shaft 1. And a L-shaped receiver 6 in which a recess 5 into which the head of the idler 3 can be fitted is formed on the side where the idler 3 appears and disappears.

More specifically, the base end of the base shaft 1 is attached to the wall surface W with screws 7. A hole 8 penetrating vertically is provided in the front portion of the base shaft 1, the diameter of the upper portion of the hole 8 is formed to be slightly smaller, and a female screw is formed in the lower portion of the hole 8.

In the hole 8, a nylon slider 3 having a hemispherical head is loosely fitted so as to be slidable and non-removable. Further, the idler 3 is urged by the spring 2 so that the head portion projects from the inside of the base shaft 1. Reference numeral 9 is a set screw that is screwed into a female screw formed in the lower portion of the hole 8 and supports the lower side of the spring 2. Reference numeral 10 is a ring-shaped cushioning material 3 formed of rubber or soft resin, and is fitted and attached to the outer periphery of the tip of the base shaft 1.

The base end of the receiver 6 is attached to the door D with a screw (not shown). Further, the tip end of the receiving tool 6 has a rounded bottom surface and is formed so that the idler 3 can easily enter the base shaft 1 against the spring 2 when the door D is opened. There is. Further, the recess 5 is a concave surface having a radius of curvature larger than the radius of curvature of the head of the idler 3.

FIGS. 3 and 4 show another embodiment in which the tilt stop mechanism of the door stop device of the present invention is applied to a door stop device fixed to the floor surface, and FIG. 3 is an explanatory view showing a usage state. 4 is a sectional view.

In the door stop 4 of this embodiment, a female screw 12 formed at the center of the set screw 9 is screwed onto an anchor bolt 11 which is erected on the floor F, and the set screw 9 is screwed onto the base shaft 1. It is worn and locked.

Since the other structure is the same as that of the above-mentioned embodiment, its explanation is omitted. The tilting mechanism of the door-stop device thus configured is used as follows.

When the door D is opened, the tip of the receiver 6 hits the head of the idler 3 of the door stop 4, and the idler 3 is pushed into the base shaft 1 against the spring 2. When the door D is further opened, the head of the mover 3 fits into the recess 5 and the door D is locked to the door stop 4.

When the door D is closed, the head of the slider 3 is moved to the spring 2
Against the urging force caused by the
The lock of the door D due to is released.

[0020]

According to the tilt stop mechanism of the door stop device of the present invention, the door is locked to the door stop by simply opening the door until it hits the door stop, and the door is locked by simply closing the door. Since it is released, there is no need to manually operate the latch as in the conventional case, which is convenient.

If the head of the idler 3 is hemispherical or the recess 5 of the receiving member 6 is a concave surface having a radius of curvature larger than the radius of curvature of the head of the idler 3, the mover 3 and the recess are formed. The engagement and disengagement of 5 becomes easier and more convenient.
