Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for holding and opening a door.

More specifically, the present invention relates to an improvement in the structure related to the operability, durability, etc. of a device that holds the open state of a pivotable door such as a double-door window door.

[Prior Art] It is extremely simple to open and hold a pivotable door by attaching a hook-shaped locking piece to the front end of the door and engaging the locking piece with a ring-shaped locking tool fixed to the opposing wall surface. Although it is stopped,
A general rotary opening / closing type door has a structure as shown in FIG. 4, which will be exemplified and described.

That is, the door A is rotatably supported on the door frame C by the hinge B, and the opened door A faces the wall D adjacent to the door frame C. Door A opened between
There is provided an open holding device E for holding the

Conventionally, as such an open holding device E, for example, one shown in FIG. 5 is known.

That is, the opening holding device E includes a protrusion-shaped main body Ea 'fixed to the surface of the door A on the wall D side, and a wear-resistant material on the outer periphery of the tip of the main body Ea' on the door A side. It is provided with an engagement protrusion Ea composed of a ring Ea ″ fitted and fixed.
On the wall D side, a plate-shaped sheet Eb 'fixed to the wall D surface,
The elastic member is provided with an engagement piece Eb formed of a curved surface corresponding to the ring Ea ″ and including a pair of opposing elastic pieces Eb ″ fixed to the seat Eb ′.

In this opening holding device E, when the door A is pivotally released and approaches the wall D, the ring Ea ″ of the engagement protrusion Ea on the door A side pushes and expands the elastic piece Eb ″ of the engagement piece Eb on the wall D side. Open and mate. When this fitting is performed, the ring Ea ″ of the engaging protrusion Ea is clamped by the elasticity imparted to the elastic piece Eb ″ of the engaging piece Eb, and the door A is prevented from separating from the wall D. Therefore, the door A is kept open.

In order to close the door, that is, to release the opening and holding of the door A, the elastic piece Eb ″ of the engaging piece Eb moves in the direction opposite to the wall D by a force greater than the elasticity of holding the ring Ea ″ of the engaging protrusion Ea. The ring Ea ″ of the engaging protrusion Ea is rotated and rotated by pressing and expanding in the same manner as described above.
The elastic piece of Eb is removed from Eb ″.

[Problems to be Solved by the Invention] In the above-described conventional open holding device E, when the open holding of the door A is released, since a special operation part is not configured, the side edge of the door A is grasped. Since the door A must be rotated by applying a considerably strong force that exceeds the elasticity of the elastic piece Eb ″ of the engaging piece Eb, it is troublesome to release the door A from being held open. It has a problem.

Further, the ring Ea ″ of the engaging protrusion Ea is the elastic piece E of the engaging piece Eb.
Since b ″ is pressed and expanded to open and hold the door A and release and hold the door A, unnecessary stress is applied to the elastic piece Eb ″ and the like of the engaging piece Eb due to the pressing and opening. As the open holding device is apt to be deformed or damaged and the frequency of use increases,
There is a problem of durability that the holding force is reduced rapidly, the open holding is easily released by wind and the door does not play the role of holding the open opening.

The present invention has been made to solve such a problem, and an object thereof is to provide a door open-holding device which is easy to hold and open the door and has good durability. It is in.

[Means for Solving the Problems] In order to achieve the above-mentioned object, an opening holding device for a door according to the present invention is fixed at a position where a lower edge of the door is close to a wall facing the opened door. The support frame, the support shaft supported by the support frame at a certain distance from the wall in the horizontal direction of the shaft and in the direction parallel to the wall, and rotatably attached to the support shaft, and the lower part has a fixed length of operation. The lever is formed on the rod, and the upper end is provided with an operating portion formed on a locking projection that can be locked and disengaged with the lower edge of the door by the rotation of the operating rod.

[Operation] According to the above-described means, when the door is pivotally opened to the wall side, the locking protrusion that touches the vicinity of the lower edge of the door is supported by the pivotal stress of the door against the weight of the operating rod. Rotate to the wall side around
Allowing the door to pass over the locking prongs, thus approaching the wall. When the door is rotated further, the lower edge of the door passes over the locking projection, and when the door is no longer subjected to the rotational stress, the locking projection returns to its original position due to the weight of the operating rod. When dripping, the locking projection will lock near the lower edge of the door, which serves to prevent the door from moving away from the wall. In other words, the door is open.

Conversely, when the operating rod is rotated in the direction away from the wall, the interlocking locking protrusion rotates and moves to the lower position of the door.
The locking protrusion is separated from the lower edge of the door. Therefore, the open holding of the door is released, and the door can be easily closed.

As described above, in the present invention, the opening and holding operation of the door is performed by opening the door by rotating the door and bringing the door into almost contact with the wall surface. To release the holding, the operating rod is rotated in the direction opposite to the wall surface. The open structure is simple and the open holding device is not subject to unnecessary stress and is not deformed or damaged. It is possible to achieve the object of providing a simple door open holding device.

[Embodiment] An embodiment of a door open holding device according to the present invention will be described below with reference to FIGS. 1 to 3.

1 and 2 show a first embodiment of a door open holding device according to the present invention.

In this embodiment, the door A side is shown to require some work.

In this embodiment, the door A is pivotally opened and provided on the side of the wall D facing the supporting frame 1, the support shaft 2, the locking projections 4 forming the operating portion 3, the operating rod 5, and the door A side. It is configured with a locking groove 6 provided.

The support frame 1 is made of a corrosion-resistant metal material such as stainless steel or a synthetic resin material so that it can be used outdoors,
Standing pieces 12 and 13 are formed at both ends of a flat plate-shaped mounting surface 11 so as to have a substantially U-shape. This support frame 1 is of the wall D,
The mounting surface 11 is joined to the surface of the wall D at a position where the lower edge of the door A is close, and the door is fastened with the screw 7.

The support shaft 2 is made of the same material as that of the support frame 1, and is formed in a cylindrical shape using a decorative bolt or the like.
The support shaft 2 is hung between the tips of both the upright pieces 12 and 13 of the support frame 1 and is rotatably supported at a fixed distance from the mounting surface 11 (wall D). Are arranged so as to be horizontal and parallel to the wall D.

The upper portion of the operating portion 3 is formed on the locking projection 4, and the lower portion is formed on the operating rod 5.

The locking projection 4 is made of the same material as that of the support frame 1, and has a structure in which a plate-shaped guide plate 42 having a curved upper side is fixed to a short rod-shaped main body 41. The locking projections 4 are arranged such that the main body 41 is arranged in a direction orthogonal to the support shaft 2 and fixed to the support shaft 2. It is possible.

The operating rod 5 is made of the same material as that of the support frame 1, and has a structure in which a weight 52 is fixed to the lower end of a long bar-shaped bar 51. The operating rod 5 has a substantially V shape and is substantially opposed to the locking projection 4 via the support shaft 2, and the bar 51
Is fixed to the support shaft 2. Therefore, the operating rod 5
The locking projection 4 is tilted to the wall D side in the state in which the hangs down.

The locking groove 6 is dug in a curved shape on the lower surface of the door A, and is protected by a contact plate 9 fixed by a screw 8.

According to such an embodiment, when the door A is pivotally opened to the side of the wall D, the locking projection 4 that touches the vicinity of the lower edge of the door A.
Is tilted in the direction of the wall D by the turning stress of the door A, and turns about the support shaft against the weight of the weight 52 of the operating rod 5 (shown by the dashed line in FIG. 1). In the contact between the locking projection 4 and the door A, the upper side of the guide plate 42 of the locking projection 4 is curved, and the locking projection 4 is bent in a substantially V shape with respect to the operating rod 5. Therefore, the lower edge of the door A comes into contact with the locking projection 4 from an oblique direction, which results in a smooth contact with the door A.

Such rotation of the locking projections 4 allows the door A to pass over the locking projections 4 and easily causes the door A to closely face in the direction of the wall D. When the locking groove 6 of A is located, the contact of the door A with the locking protrusion 4 is released,
At that time, the weight of the operating rod 5 causes the locking projection 4 to rotate in the opposite direction to enter the locking groove 6 and return to the original posture (shown by the solid line in FIG. 1).

The locking projection 4 that has entered the locking groove 6 does not easily rotate due to the weight of the weight 52 provided at the lower end of the operating rod 5, and retains its initial posture. It will not be easily separated from the groove 6. That is, the open state of the door A is maintained. By setting the length of the bar 51 longer than the distance between the support shaft 2 and the wall D, when the door A tries to rotate in the closing direction, the weight 52 portion of the operating rod 5 contacts the wall D. (Indicated by the chain double-dashed line in FIG. 1), on the other hand, the locking projection 4 comes into contact with the contact plate 9 of the locking groove 6. At this time, the locking projection 4 tilted in the direction of the wall D becomes upright and locked deeply in the locking groove 6, so that the door A is surely prevented from rotating in the closing direction. become.

Further, when the operating rod 5 is gripped by hand and rotated in the direction opposite to the wall D, the locking projection 4 rotates in the direction of wall D (illustrated by a chain line in FIG. 1).
However, the locking projection 4 is to be separated from the locking groove 6,
The door A will be released. Since the operating rod 5 has a structure in which the weight 52 is provided at the lower end of the bar 51 having a fixed length, the operation portion 3 can be easily gripped by the hand and easily rotated.

FIG. 3 shows a second embodiment of a door opening holding device according to the present invention.

In this embodiment, the door A side does not require any work.

In this embodiment, the locking groove 6 provided in the door A in the first embodiment described above is removed, and the locking projection 4 is provided on the wall D of the door A.
It is designed to engage with the lower edge of the surface on the opposite side.

According to this embodiment, the locking groove 6 of the first embodiment is replaced with the lower edge of the surface of the door A on the side opposite to the wall D, and the same action and effect as the first embodiment are obtained, but in addition to this Since the door A does not require excavation work of the locking groove 6, there is an advantage that the installation work is easy.

[Effects of the Invention] As described above, the door open-holding device according to the present invention pushes the door open, and the lower edge of the door passes over the locking projection to ensure the open-holding. There is a weight,
By simply grasping the operating rod that is easy to grasp and rotate with your hand and rotating the locking projection, the locking projection is disengaged from the door.
Since the open holding of the door can be released, the operation of releasing the open holding of the door can be performed very easily.

Furthermore, since the locking projection has a simple structure in which it locks and disengages in the vicinity of the lower edge of the door, unnecessary stress that would cause deformation and damage to the open holding device is not applied, and therefore durability is improved. It has a good effect that it can be used for a long time.
