Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door opening device, and more particularly to a door opening device that maintains a door, such as a door, in an open state at a predetermined angle.

There are cases where it is desired to keep doors such as entrances and exits open at a predetermined angle when carrying in and out of luggage or when improving indoor ventilation. In such cases, conventional methods have been to press a small wedge-shaped piece between the door stile and the floor, or to place a weight on one or both sides of the door to maintain the door in the desired open state. It was normal to leave it alone. However, in such cases, handling is troublesome, and moreover,
There was no way to reliably keep the door open. Particularly when the door is equipped with a door closer, the wedge-shaped pieces tend to come off or the weights tend to shift. Furthermore, weights and the like often got in the way of loading and unloading luggage or people getting in and out.

The purpose of the present invention is to provide a door opening device that is easy to handle, can reliably maintain the door in a predetermined open state, and does not obstruct the loading and unloading of luggage or the access of people. It is in.

The present invention provides a rod that is slidably engaged with a rail at one end and can be locked at a predetermined position on the rail, and the other end of the rod is rotated toward either a door or a doorway. At the same time, the rail is attached to either the door or the doorway, and when the door is opened at a predetermined angle, the rod is locked at a predetermined position on the rail, so that the rod is just held onto the holding bar. The purpose of the present invention is to achieve the above object by performing the following functions.
Note that the term "door" as used herein includes both a door and a casement window, and the term "doorway" includes both a doorway and a window.

Hereinafter, embodiments of the present invention will be described based on the drawings.

1 and 2 show an embodiment of the door opening device according to the present invention, and in these figures, a substantially flat U-shaped rail 2 is attached to the upper stile 1A of the door 1 as a door. It is provided along the longitudinal direction of 1A. The rail 2 is fixed on the upper stile 1A via wood screws 3 at both ends,
The longitudinal center portion of the rail 2 is parallel to the upper stile 1A so as to have a predetermined gap between the rail 2 and the upper stile 1A.

As shown in FIG. 2, the rail 2 has an engagement groove 4 bored in the center in the width direction along the longitudinal direction of the rail 2, and the right end of the engagement groove 4 in the figure has a door opening. An escape hole 4A is provided on the open end side of the engagement groove 4.
are provided continuously. Furthermore, a locking member 5 is provided at the other end of the engagement groove 4 .

As shown in an enlarged view in FIG. 3, this locking member 5 is formed by stacking a plurality of thin metal plates to have a predetermined thickness and is given flexibility. It is attached to the side surface of the upper stile 1A via a rivet 6. Further, the locking member 5 is provided with a locking hole 5A having a substantially keyhole shape, and the locking hole 5A is opened at the right edge in the figure. Furthermore, since the locking member 5 is formed to have flexibility, the opening width of the right end opening of the locking hole 5A can be expanded within a predetermined range.

On the other hand, in FIG. 1, an upper frame 9 and a vertical frame 10 having a convex cross section are provided on the inner peripheral edge of the entrance 8 as a doorway.
is provided, and one end of a rod 11 is rotatably attached to the entrance/exit 8 via the upper frame 9. The rod 11 is formed into a long flat plate having approximately the same length as the rail 2, and is rotatably attached to the mounting plate 13 via a rotation shaft 12 at the left end in the figure. Mounting plate 13
A nylon washer 14 is interposed between the two. Further, the mounting plate 13 is fixed to a seat plate 15 provided inside the upper frame 9 with screws 16, so that the mounting plate 13 and the seat plate 15 sandwich the upper frame 9. and is fixed to the upper frame 9.

An engagement shaft 18 is provided at the other end of the rod 11 to protrude toward the upper stile 1A, and the distal end of the engagement shaft 18 is slidably inserted into the engagement groove 4.
A small cylindrical pin 19 is attached to the tip of the engagement shaft 18 from the upper stile 1A side of the rail 2.
This pin 19 prevents the engagement shaft 18 from coming off from the engagement groove 4 . Furthermore, this pin 1
9 can be removably press-fitted into the locking hole 5A of the locking member 5.

Next, the operation of this embodiment will be explained.

FIG. 4 shows the door 1 in a closed state, and in this figure, the rod 11 and the rail 2 are superimposed over substantially the entire area along the longitudinal direction, and the upper stile 1A and the upper frame 9 It is stored in the gap between the In addition, in this state, the engagement shaft 18 provided on the distal end side of the rod 11
The pin 19 is disposed at a predetermined position near the right end of the engagement groove 4 in the figure.

When the door 1 is opened from this state by pulling it toward the front in the figure, the engagement shaft 18 and pin 19 slide toward the left end in the figure along the engagement groove 4 of the rail 2. When reaching the locking member 5 at the left end, the pin 19 is press-fitted into the locking hole 5A and held by the locking member 5, and in this state, the door 1 is held in a predetermined position as shown in FIG. It will remain open at an angle.

Also, from the open state shown in FIG.
To close, simply turn door 1 counterclockwise in the diagram.
That is, when the pin 19 is rotated toward the doorway 8 side, it is disengaged from the engagement hole 5A, and when the door 1 is closed, the pin 19 is moved back to the right end of the rail 2 in the figure, as shown in FIG. It will be placed in

According to this embodiment, the door 1 can be kept open at a predetermined angle without using wedge-shaped pieces, weights, etc. as in the conventional case. Therefore, it is extremely convenient when carrying in and out of luggage through the entrance/exit 8, when obtaining ventilation, etc.

Further, in order to maintain the door 1 at a predetermined open angle, no special operation is required; simply open the door 1 to the predetermined angle and insert the pin 19 into the locking hole 5A of the locking member 5. Because it only needs to be press-fitted,
It has the effect of being extremely easy to handle.

In particular, since the locking member 5 is constructed by stacking a plurality of metal plates, it has sufficiently high strength, so that the door 1 can be opened and closed many times.
Pin 1 for approximately keyhole-shaped locking hole 5A of locking member 5
Even if the locking member 9 is repeatedly inserted and removed, the elastic expansion action of the locking hole 5A is reliably maintained over a long period of time, and the locking member 5 has great durability.

Moreover, as shown in FIG. 4, when the door 1 is closed, the rail 2 and rod 1
1 is housed in the gap between the upper stile 1A of the door 1 and the upper frame 9. That is, the rail 2 and rod 11 are hidden in the gap, so they do not get in the way and have a good appearance. There is an effect that

Furthermore, when the door 1 is in the open state as shown in FIG. Even if door 1 is open, rail 2 or rod 1 will be passed.
1 does not get in the way, and there is an effect that it does not get in the way at all when carrying in/out luggage or people entering/exiting the entrance/exit 8.

In the above-described embodiment, the rail 2 is installed on the upper stile 1A of the door 1, but the rail 2 is not limited to the upper stile 1A. It may be attached along the longitudinal direction of 1A.

In addition, although the rail 2 is attached to the door 1 and the rod 11 is attached to the doorway 8 side, it is assumed that the rail 2 is attached to the doorway 8 side and the rod 11 is rotatably attached to the door 1 side. It may be something that you have.

Furthermore, although the mounting position of the locking member 5 with respect to the rail 2 is not particularly displaced, the mounting position of the locking member 5 may be changed by, for example, attaching the locking member 5 to the rail 2 via a mounting screw. As long as it can be easily displaced, it is easy to selectively change the opening angle of the door 1 in various ways. Furthermore, although the length of the rod 11 is assumed to be constant, if the length of the rod 11 is made adjustable by, for example, combining two rod-like members, then the length of the locking member 5 can be adjusted. Even if the mounting position remains unchanged, the opening angle of the door 1 can be selectively adjusted in various ways.

Furthermore, the opening device according to the present invention is not limited to the door 1 of the entrance/exit 8, but can also be easily applied to a casement window of a window, etc.

As described above, the present invention has the advantage of providing a door opening device that is easy to handle, can reliably maintain the door in a predetermined open state, and does not get in the way.
