Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a door opening holding device for holding a door body typified by a swing door (opening door) in an open state, and particularly to a door opening operation by operating a foot. The present invention relates to a foot-operated door opening and holding device that can easily hold and release the door.

[Conventional technology]

Conventionally, as a mechanism for holding a swing door in an open position, a hook fitting engageable with a door stopper is attached to the door body side, and after opening the door body, this hook is hung on the door stopper side. What has become known.

Furthermore, the simplest method is to prepare a wedge-shaped piece of wood or an elastic pad, sandwich it between the opened door body and the floor, and make the door body immobile by wedge engagement. is there.

[Problems to be solved by the invention]

However, in a mechanism using a hook, it is necessary to bend down after opening the door body and hook the hook on the door stopper, and it is also necessary to remove the hook when closing the door body thereafter. In particular, when the door body is opened and brought close to the wall side, it is necessary to hook the hook to the door stopper or to release the hook. Often. For this reason, there is a problem that such an operation is complicated when carrying a baggage or the like.

Similarly, in the method of sandwiching a piece of wood or the like at the lower end of the door body, it is necessary to manually attach and remove the piece of wood, and this is inconvenient because the piece of wood or the like often disappears.

In view of the above problems, an object of the present invention is to realize a door opening holding device that can be operated with a toe without using hands.

[Means for Solving the Problems] In order to solve the above problems, the present invention employs the following means. First, a first means is a spherical door stopper which can be rolled on the floor surface and abuts on the lower edge of the door main body, one end side is fixed to the building main body side, and the other end side is connected to the door stopper. In the door opening holding device having a flexible anchoring member and holding the door body in an open state, the anchoring member is provided between a lower edge of the door body and a floor surface of the building body. It is a thickness that can pass through the gap, and the attachment point on one end side of the anchoring member is located inside the turning locus of the tip of the door body. Here, it is preferable that the door stopper is rotatable with respect to a pivot member connected to the anchoring member and passing through the center of the door stopper.

The second means is provided with a mounting portion mounted and fixed to the building body side and a door stopper abutting on a lower edge portion of the door body at a front end portion, and pivots between the retracted position and the door stop position of the door stopper. A revolving arm member supported by the mounting portion so as to hold the door body in an open state, wherein the retracted position of the door stopper is located outside of a revolving locus of a tip of the door body. Wherein the door stop position of the door stopper is inside the turning locus, and a force in the door closing direction received by the door stopper from the door main body passes through a turning center of the turning arm member. It is characterized by. Here, an elastic urging member having an urging direction change point in the middle of the turning area of the turning arm member, and urging the turning arm member in one of the retracted position direction and the door stop position direction. May be provided.

Instead of providing the elastic urging member, when the door stopper is at the retracted position, the pushed member is within the turning locus of the tip of the door body and is pushed by the door body; There may be provided a transmission mechanism for turning the turning arm member to move the member to displace the door stopper from the retracted position to the door stop position. Here, the transmission mechanism is an auxiliary turning arm integrally connected to the turning arm member and having an arm length shorter than the arm length of the turning arm member. The auxiliary turning arm is used as the pushed member. Door stopper fixed to the tip of the door.

[Action]

First, according to the first means, when the door body is held in the open state, the door body is opened and brought close to the wall side, and the door stopper tethered at the toe is rolled to bypass the door body, Is moved to the side (rear side) opposite to the side (front side) facing the wall surface, and is set in contact with the lower edge of the door body. Here, since the anchoring member is thick enough to pass through the gap between the lower edge of the door body and the floor of the building, the anchoring member enters the gap, and the door stopper is moved only by operating the toe of the door body. Can be set on the back side. In particular, since the door stopper can be rolled even if it is anchored, it can be easily set even by awkward operation of the foot. In particular, since the flexible anchoring member is used, the position of the door stopper can be adjusted. After the door stopper is located on the back side of the door body, when the door body is released from restraint and the door body turns in the closing direction by a return spring or the like, a return force is applied to the door stopper, and the front end of the door body is applied. Although it may move to the track side, since the attachment point of the anchoring member is in the inner area of the tip end track of the door body, when the return force applied to the door stopper pulls the anchoring member straight, that is, the door body And the extended anchoring member stops at right angles, and does not pivot in the closing direction any further. When the anchor member is used, until the return force applied from the door body to the door stopper passes through the anchor point of the anchor member,
Although the door stopper is moved, it is always automatically positioned and stopped at that position. Therefore, the setting position of the door stopper may be relatively rough. In this way, the door body can be maintained in the open state by moving the spherical door stopper to the rear side of the door body with the toes without using the hands. Conversely, when closing the door body, the ball-shaped door stopper is moved out of the tip trajectory of the door body with the tip of the foot. This eliminates the door stopper in the turning area of the door body, so that the door body can be closed.

Here, when the door stopper has the pivot member, the door stopper is rotatable with respect to the anchoring member, so that the anchoring member is unlikely to be warped or twisted, and the anchoring member is located in the gap at the lower edge of the door body. Can pass without clogging,
In addition, damage to the anchoring member itself can be reduced. Furthermore, since the door stopper itself only rotates in one direction by rotating the pivot member like an axle, the door stopper tends to pivot around the attachment point of the anchoring member rather than being able to move randomly in the anchoring range. The rolling locus of the door stopper can be made uniform. For this reason, even if the toe operation is awkward,
Easy to set the door stopper.

The second means differs from the first means in that instead of the anchoring member, the second means has a rigid swiveling arm member. When the anchoring member is used, as described above, the set of the door stop position is automatically positioned by the force applied from the door body. However, in the second means, the door stop position is located inside the rotation locus. Thus, the force in the door closing direction received from the door body to the door stopper passes through the center of rotation of the swing arm member. In such a state, no matter what the force in the door closing direction, the torque (rotational moment) of the turning arm member due to this disappears and becomes zero.
The turning arm member stops without rotating. Therefore, when the door stopper is at the door stop position, the door stopper is at the fixed point, and the turning of the door body is stopped. Also in this second means, since the door stopper pivots between the retracted position and the door stop position by the pivot arm member, the door can be moved between the retracted position and the door stop position even if the toe operation is awkward. Easy to set stopper.

In particular, when the elastic urging member is provided in the second means, the door stopper is not at a position between the retracted position and the door stop position, but is always at either position. Further, when changing the set position, the door stopper may be operated with the foot until the bias direction change point is exceeded, and the operability of the foot is improved.

In the configuration in which the pushed member and the transmission mechanism are provided instead of providing the elastic biasing member, the door body pushes the pushed member by opening the door body,
The turning arm member is displaced to the door stop position via the transmission mechanism,
The open state of the door body can be automatically maintained. Therefore, it is possible to eliminate the operation of the toes for holding the door open after the door body is opened, and it is possible to further improve the operability.

In particular, in the configuration using the auxiliary swing arm and the door stopper, the auxiliary swing arm can be formed by bending the swing arm member, and the number of components of the transmission mechanism can be reduced and the cost can be reduced.

〔Example〕

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

First Embodiment FIGS. 1 and 2 show a door opening holding device according to a first embodiment of the present invention. As shown in these figures, a door opening holding device 1 of the present example includes a flexible rod-shaped connecting member (anchoring member) 2 such as a vinyl-coated steel wire, a fixing screw 3 connected to the base end thereof, It comprises a spherical door locking member (door stopper) 4 connected to the tip of the connecting member 2. The spherical door locking member 4 is approximately the size of a golf ball, and a through hole 5 is formed through the center of the door locking member 4. A connecting metal (a pivot shaft) for connecting the connecting member 2 to the spherical member is provided here. Member 6 is rotatably inserted. The through hole 5 has a large-diameter hole 5a on one side and a small-diameter hole 5b on the other side, and an annular step portion 5c is formed at a connection portion between them. The connecting fitting 6 inserted into the through-hole 5 from the side of the large-diameter hole has a bulging head 6a for retaining which can be engaged with the step 5c, and a continuous bulging head 6a. A rod-shaped leg 6b and an annular portion 6c formed at the tip of the leg 6b are connected to the flexible connecting member 2 described above. Here, the connecting member 2 has a small cross section (thickness) that can freely pass through the gap 9 between the lower end 7a of the door body 7 and the floor surface 8 of the building. The locking member 4 is a sphere having a diameter larger than the gap 9. Fixing screw 3
Is fixed to the building side by screwing into the inside of the door tip trajectory at the lower end of the wall 10 where the open door body 7 approaches.

As shown in FIG. 1, when the door body 7 is opened and brought close to the wall surface side, the door locking member 4 anchored at the toe
Is rolled around the door body 7 and moved to the side (rear side) opposite to the side (front side) where the door body 7 faces the wall surface, and is set in contact with the lower edge of the door body 7. here,
Since the thickness of the connecting member 2 is such that it can pass through the gap 9 between the lower edge of the door body 7 and the floor surface 8 of the building body, the connecting member 2
Can enter the gap 9, and the connecting member 2 can be set on the back side of the door body 7 only by operating the toes. In particular, the door can be rolled even when the door locking member 4 is anchored by the connecting member 2, so that it can be easily set by awkward operation of the toes. After the state where the door locking member 4 is located on the back side of the door body 7,
When the door body 7 is released from the restraint and the door body 7 returns to the closing direction and turns by the return spring or the like, a return force is applied to the door locking member 4 and the door body 7 moves toward the leading end of the door body 7. obtain. However, since the attachment point of the connecting member 2 (the position of the fixing screw 3) is in the region inside the trail of the front end of the door body 7, when the return force applied to the door locking member 4 pulls the connecting member 2 straight, , Door body 7
Stops in a state in which the connecting member 2 is pulled and extended at right angles to the connecting member 2 and does not pivot any more in the closing direction. By the way, when the flexible connecting member 2 is used, the door body 7
The door locking member 4 is moved until the return force applied to the door locking member 4 from the door passes the mounting point of the door locking member 4 (the position of the fixing screw 3), but it is always automatically positioned at that position. Stop being being. Therefore, the setting position of the door locking member 4 may be relatively rough. In this manner, the door body 7 can be maintained in the open state by moving the spherical door locking member 4 to the back side of the door body 7 with the feet without using the hands. Conversely, when closing the door body 7,
The spherical door locking member 4 is moved out of the path of the front end of the door body 7 by the foot. As a result, the door locking member 4 is eliminated in the turning area of the door body 7, so that the door body 7 can be closed.

In this example, since the door locking member 4 has the connecting fitting (pivot member) 6 and the door locking member 4 is rotatable with respect to the connecting member 2, the connecting member 2 may be warped or twisted. Is less likely to occur, the connecting member 2 can pass through the gap 9 at the lower end edge 7a of the door body 7 without clogging, and the damage of the connecting member 2 itself can be reduced. Further, since the door locking member 4 itself rotates only in one direction by rotating the connection fitting 6 like an axle, the door locking member 4 can move at random in the anchoring range. The tendency to turn around the mounting point (position of the fixing screw 3) becomes stronger, and the rolling locus of the door locking member 4 can be standardized. Therefore, it is easy to set the door locking member 4 even when the toe operation is not awkward.

In this example, the connecting member 2 is a rod-shaped member, but this may be a thin plate-shaped member, for example. In addition, it goes without saying that the material of each part described above may be any.

Second Embodiment FIGS. 3 and 4 show another embodiment of the present invention. First, as shown in FIG. 3, the door opening holding device 21 of this example has a mounting portion 22 for mounting on the building body side, and the mounting portion 22 allows the turning arm member 23 to have a predetermined range. Is supported so as to be able to turn. A door locking member 24 is attached to the tip of the turning arm member 23. Further, the turning arm member 23 is attached to the mounting portion 22.
The position is regulated by a position regulating mechanism 25 incorporated therein into a first position (retreat position) shown in the drawing and a second position (door stop position) shown by imaginary lines.

The mounting part 22 includes a metal rectangular base 221,
A fixing screw 222 for fixing the base to the floor 8;
It comprises a metal cover 223 that covers the base upper surface 221a. Further, the base end 23 of the revolving arm member 23 is provided on the base upper surface 221a.
A shaft 224 that rotatably supports 1 is fixed. The revolving arm member 23 is formed of an L-shaped metal fitting as a whole, and a step portion 232 bent upward is formed at a central bent portion thereof. A gob ball-sized door locking member 24 is fixed to the upper surface of the tip of the turning arm member 23.

On the other hand, the position regulating mechanism 25 for positioning the turning arm member 23 at the first and second positions includes the following components. That is, on the base upper surface 221a, a spring receiving pin 251 is fixed at a position near the base end of the turning arm member 23, and the spring receiving pin 251 is also located on the side of the turning arm member 23 away from the base end 231. A pin 252 is fixed, and a spring 255 is stretched between the pins 252 in a slightly extended state. Further, the cover 223 is provided with a stopper 253 to which the side surface of the revolving arm member 23 at the first position shown by the solid line in FIG.
Further, a stopper 254 is formed that can abut the side surface of the turning arm member 23 at the second position shown by the imaginary line in the figure. There is a biasing direction change point on a straight line passing through the spring receiving pin 251 and the shaft 224, and the turning arm member 23 is spring biased in the first position direction or the second position direction.
As a result, it is positioned in the first position direction or the second position direction.

In the door opening and holding device 21 having this configuration, when the door locking member 24 is at the first position (the retracted position) with respect to the rotation locus 26 of the leading edge of the door body 7, the position is outside the rotation locus 26. When the door lock member 24 is at the second position (door stop position), the force in the door closing direction received by the door lock member 24 from the door main body 7 is located inside the rotation locus 26 and the turning arm. The position passes through the center of rotation of the member 23. When using the door opening holding device 21, the turning arm member 23 is usually set to a first position shown by a solid line in the drawing. In this state, the door body 7 is opened, and when the state shown in FIG. 4 is attained, the turning arm member 23 is turned to the second position by the tip of the foot against the spring force of the spring 255. After the turning arm member 23 is turned halfway, the turning arm member 23 is pulled toward the second position by the spring 243 and hits the stopper 254 and stops. As a result, the door locking member 24 supported at the tip of the turning arm member 23 is set to the second position where the door locking member 24 can contact the lower end portion of the door body 7. In such a state, whatever the force in the door closing direction,
The force passes through the center of rotation (the shaft 224), and the torque (rotation moment) of the turning arm member 23 is zero, so that the turning arm member 23 stops without rotating. Therefore, the door locking member
When 24 is in the second position (door stop position), the door locking member 24 is at the fixed point, and the turning of the door body 7 is stopped. Also in this example, the door locking member 24 is
Since the turning locus moves between the retracted position and the door stop position by 23, the door locking member 24 can be easily set at the retracted position and the door stop position even when the toe operation is awkward.

Next, when closing the door body 7 thus opened and held, the turning arm member 23 or the door locking member 24 may be turned toward the first position with the use of a foot or the like. At the time of this turning, the turning arm member 23 also receives the spring 255
Pulled toward the first position by the stop
Stops when it hits 243. As a result, the door locking member 2
4 is located off the rotation locus 26 of the door body,
The door body 7 can be closed freely.

Third Embodiment Next, FIGS. 5 and 6 show a third embodiment of the present invention. The door opening and holding device 31 of the present embodiment has a metal L-shaped base 32 and a fixing screw 33 for fixing the L-shaped base 32 to the wall surface 10. A pin 322 is fixed to a central portion of the horizontal surface 321 of the base 32, and a turning arm member 34 made of a metal rod bent in an L shape as a whole is supported so as to be able to turn around the pin 322. . That is, the revolving arm member 34 is rotatably supported at the bent portion 341 with respect to the pin 322. One side of the revolving arm member is a long arm portion 342, and the other side is a short arm portion. It is 343. The distal end of the longer arm portion 332 supports a columnar door locking member 35, and the distal end of the shorter arm portion 343 supports a door contact member 36 having the same shape. Here, a protrusion 323 for a stopper is formed on the base 32, and the turning arm member 34 that has turned from the second position shown by the imaginary line to the first position shown by the solid line in FIG. It comes into contact with the projection 323 and is held at the first position.

Also in the door opening holding device 31 of this configuration, similarly to the above-described second embodiment, the turning arm member and the door locking member 35 supported by the turning arm member are set to the first position (retreat position). Is located outside the rotation locus 26 of the front end of the door body 7, and when set at the second position (door stop position), it is inside this locus, and the door is locked from the door body 7. The force in the door closing direction applied to the member 35 is at a position passing through the center of rotation (pin 322) of the swing arm member 34.

In the door opening holding device 31 of the present example, the door locking member
When the door body 7 is opened to the wall when 35 is in the first position, first, the door body 7 abuts against the door contact member 36,
As a result, the door contact member 36 is moved to the first
Is pivoted from the position to the second position indicated by the imaginary line, so that the swivel arm member 34 also pivots as a whole toward the second position, so that the door locking member 35 ,
It is set at the second position inside the rotation locus 26 of the door body 7. In such a state, no matter what the force in the door closing direction, the force passes through the center of rotation (pin 322) and the torque (rotation moment) of the rotation arm member 34 thereby becomes zero. The member 34 stops without rotating. Therefore, when the door locking member 35 is at the second position (door stopping position), the door locking member 35 is at the fixed point, and the turning of the door body 7 is stopped. On the other hand, to close the door body held open,
What is necessary is just to remove the door locking member 35.

In this example, the open state of the door body 7 can be automatically maintained by opening the door body 7. Therefore, it is possible to eliminate a foot operation for holding the door body 7 open after the door body 7 is opened, and it is possible to further improve operability. The door contact member 36 is a swing arm member.
34 can be formed by bending, so that the number of parts of the transmission mechanism is small, and the cost can be reduced.

[Effect of the invention]

As described above, the method of stopping the door body according to the present invention is a method of pivoting with the attachment point of the flexible anchoring member or the door stopper for anchoring the door stopper with the force received by the door stopper from the open door body. It is characterized in that it is set so as to pass through the turning center of the arm member and the torque of the turning arm member is set to zero to keep the door open. Therefore,
The following effects are obtained.

In the means using the door stopper and the anchoring member,
The door stopper can be set on the back side of the door body simply by operating the foot. In particular, since the door stopper can be rolled even if it is anchored, it can be easily set even by awkward operation of the foot. In particular, because a flexible anchoring member is used,
The position of the door stopper can be adjusted. The door stopper is moved until the return force applied from the door body to the door stopper passes the attachment point of the anchoring member, but the door stopper is always automatically positioned and stopped at that position. Therefore, the setting position of the door stopper may be relatively rough. In this way, the door body can be maintained in the open state by moving the spherical door stopper to the rear side of the door body with the toes without using the hands. Conversely, when closing the door body, the ball-shaped door stopper is moved out of the tip trajectory of the door body with the tip of the foot. This eliminates the door stopper in the turning area of the door body, so that the door body can be closed.

When the door stopper has a pivot member, the door stopper is rotatable with respect to the anchoring member, so that the anchoring member is unlikely to be warped or twisted, and the anchoring member does not jam in the gap at the lower edge of the door body. It can pass, and the damage of the anchoring member itself can be reduced. Furthermore, since the door stopper itself only rotates in one direction by rotating the pivot member like an axle, the door stopper tends to pivot around the attachment point of the anchoring member rather than being able to move randomly in the anchoring range. The rolling locus of the door stopper can be made uniform. Therefore, it is easy to set the door stopper even when the toe operation is awkward.

In the means using the door stopper and the swing arm member, the door stopper swings between the retracted position and the door stop position by the swing arm member,
Even if the toe operation is awkward, it is easy to set the door stopper at the retracted position and the door stop position.

When the elastic urging member is provided, the door stopper is not located between the retracted position and the door stop position, but is always located at either position. Further, when changing the set position, the door stopper may be operated with the foot until the bias direction change point is exceeded, and the operability of the foot is improved.

When the driven body and the transmission mechanism are provided, when the door body is opened, the door body pushes and moves the driven member, the turning arm member is displaced to the door stop position via the transmission mechanism, and the door body is automatically moved. The door body can be kept open. Therefore, after the door body is opened, the toe operation for keeping the door open can be eliminated, and the operability can be further improved.

In the configuration using the auxiliary swing arm and the door stopper, the auxiliary swing arm can be formed by bending the swing arm member, the number of components of the transmission mechanism is small, and the cost can be reduced.
