(First Embodiment)
First, the stopper 10 according to the first embodiment will be outlined with reference to FIG.
FIG. 1 is a schematic front view of a door with a stopper (hereinafter, simply referred to as “door”) 100 including the stopper 10 according to the first embodiment.
As shown in FIG. 1, the stopper 10 includes a stopper operating device (hereinafter, simply referred to as “operating device”) 20 provided with a knob 11 and a rotary reciprocating operating device (hereinafter, simply referred to as “operating device”) provided at a lower portion of the door 100. (Simply referred to as "actuator") 30 is connected by an operation transmission unit 12 such as a wire 12.

The knob 11 is a handle lever 11A that is inserted into the operating device 20 from both the outer surface and the outer back surface of the operating device 20, and is rotated around the knob shaft portion 14 inside the operating device 20 by the rotation operation of the handle lever 11A. It is composed of a knob internal mechanism 11B (FIG. 2).

In the stopper 10 according to the first embodiment, in addition to the general function of operating the protrusion and impacting of the latch bolt 17 by the rotation of the knob 11, the operation transmission unit 12 receives a rotation of a predetermined angle θ or more. Gives power such as tension. Then, the operation transmission unit 12 transmits this power to the connected operating device 30, and operates the operating device 30.
Here, the predetermined angle θ refers to the rotation angle centered on the knob shaft portion 14 from the natural posture of the knob 11 when power starts to be transmitted to the operating device 30 via the operation transmission unit 12.
The natural posture means a state in which the handle lever 11A (knob 11) is not rotated.

As shown in FIG. 1, for example, the actuating device 30 is fixed to the lower portion of the door 100 so that the abutting shaft (butting member) 19 is along the vertical direction. The abutting shaft 19 receives power from an operation transmission unit 12 that functions as an operation unit and projects from the lower end side of the door 100 toward the floor surface 50. Friction occurs at the contact portion between the abutting shaft 19 and the floor surface 50, so that the door 100 is fixed at an arbitrary opening angle and is maintained in an open state.

The operation transmission unit 12 is typically a wire 12, but is not limited to the wire 12. For example, the operation transmission unit 12 may be one that is hydraulically transmitted like a drive device such as a motorcycle. Further, the operation transmission unit 12 may be a set of a transmitter and a receiver. In this case, when the rotation of the knob 11 exceeds the predetermined angle θ, the operating device 30 is controlled by transmitting an operating signal from the transmitter installed in the operating device 20 to the receiver installed in the operating device 30.

Next, the configuration of an example of the operating device 20 will be described in detail with reference to FIG. 2 in addition to FIG.
The operating device 20 is mainly configured by accommodating operating members such as the knob internal mechanism 11B, the latch bolt support portion 21, and the slider 22 in the casing 23.
The knob internal mechanism 11B is, for example, a plate member that is fixed to the knob shaft portion 14 of the handle lever 11A inserted from the outside of the casing 23 and rotates together with the knob shaft portion 14 by the rotation operation of the knob 11.

In the knob internal mechanism 11B, the latch bolt arm portion 11a and the slider arm portion 11b extend along the casing 23 surface at a predetermined angle with respect to, for example, the knob shaft portion 14.
As shown in FIG. 2, for example, the latch bolt arm portion 11a extends radially from the knob shaft portion 14 and then bends in a direction away from the latch bolt 17 to come into contact with the latch bolt support portion 21.

The latch bolt support portion 21 has an approximate shape of a right triangle having a contact side with the latch bolt arm portion 11a as a hypotenuse, a side extending in the horizontal direction as a short side, and a side extending in the vertical direction as a long side. On the plate surface of the latch bolt support portion 21, a first locking projection 26a provided along the short side near the short side and a second locking protrusion provided on the top formed by the long side and the oblique side 21a. The protrusion 26b is provided toward the casing 23.
The latch bolt support portion 21 is slidable in the horizontal direction by locking the locking projections 26a and 26b one by one in the bolt support grooves 27a and 27b horizontally provided in the casing 23. Locked to.

The hypotenuse 21a of the latch bolt support portion 21 has a latch bolt support portion 21 in which the latch bolt arm portion 11a abuts on the latch bolt support portion 21 when the handle lever 11A is rotated within a predetermined angle θ from the horizontal state. It has a bow-shaped shape so as to slide.
Due to the structure of the latch bolt support portion 21 and the latch bolt arm portion 11a, the latch bolt 17 is pulled into the casing 23 when the handle lever 11A rotates within a predetermined angle θ.

The latch shaft 17a connecting the latch bolt 17 and the latch bolt support portion 21 is provided with a coil spring 31 whose end abuts on the retaining protrusion 29 fixed to the casing 23. The restoring force of the coil spring 31 contracted by the slide of the latch bolt support portion 21 exerts a force on the latch bolt 17 to return to the original state.
Further, the first torsion spring 32 fixed at a position slightly separated from the knob shaft portion 14 also comes into contact with the knob internal mechanism 11B, and imparts a rotational restoring force for returning the knob internal mechanism 11B to its natural posture. ing.

Further, the casing 23 is provided with two left and right slider locking groove holes 33 along the vertical direction, for example. For example, a box-shaped slider 22 is bridged and locked in the left and right slider locking groove holes 33.
The bottom of the slider 22 is in contact with the end of the bent slider arm 11b after extending radially from the knob shaft 14.
The rotation of the slider arm 11b around the knob shaft 14 pushes the slider 22 up along the slider locking groove 33 from the lower edge of the slider locking groove 33.
A locking hole is provided in the slider 22, and a wire 12 (operation transmission portion 12) having a locking ball 12a formed at an end thereof is passed through the locking hole.

The wire 12 is covered with an outer tube 37 which is several centimeters shorter than the wire 12. The upper end of the outer tube 37 is fixed to the lower side of the casing 23, and only the wire 12 projects into the casing 23 and penetrates the locking hole of the slider 22. When the knob 11 is non-rotating, the locking ball 12a is located several centimeters above the slider 22 at the lower end of the slider locking groove 33.
When the slider arm portion 11b rotates around the knob shaft portion 14 by a predetermined angle θ or more, the locking ball 12a is caught in the locking hole of the slider 22, and the slider 22 pulls the wire 12 upward.

In FIGS. 3A to 3C, the play of rotation of the knob 11 until the wire 12 operates is secured by the separation between the slider 22 and the locking ball 12a of the wire 12 at the lower end. doing. That is, even if the arm portion 11b for the slider pushes the slider 22 upward, the locking ball 12a is not immediately locked to the slider 22, and the wire 12 is not pulled. However, the play portion up to the towing of the wire 12 may be provided in another configuration. That is, the extension angle of the slider arm portion 11b may be changed so that the slider arm portion 11b does not come into contact with the slider 22 until the predetermined angle θ. In this case, even if the locking ball 12a is always locked to the slider 22, the wire 12 is not pulled unless the knob 11 is rotated to a predetermined angle θ, so that the separation distance between the locking ball 12a and the slider 22 is played. The same effect as when it was set to is obtained.

Next, the door opening / closing operation and the wire operation by the operating device 20 realized by the above configuration will be described with reference to FIG.
FIG. 3A is a diagram showing an operating device 20 in which the knob internal mechanism 11B is in a natural posture, and FIG. 3B is a diagram and a diagram showing an operating device 20 in a state where the knob internal mechanism 11B is rotated to a predetermined angle θ. 3 (C) is a diagram showing an operating device 20 in a state where the knob internal mechanism 11B is rotated by a larger angle than a predetermined angle θ.

When the knob internal mechanism 11B is in the natural posture, as shown in FIG. 3A, the latch bolt 17 protrudes from the casing 23, and none of the springs 31 and 32 is in a state where a restoring force is applied. ..

As shown in FIG. 3B from this state, the slider 22 is slid upward by the slider arm portion 11b, but the wire 12 is not pulled until the predetermined angle θ is, for example, about 30 °. Therefore, the latch bolt support portion 21 is pushed by the latch bolt arm portion 11a and moves horizontally along the bolt support grooves 27a and 27b, and only the operation of pulling the latch bolt 17 into the casing 23 is performed. That is, when the rotation of the knob 11 is equal to or less than the predetermined angle θ, the latch bolt 17 can be pulled into the casing 23 to open the door 100, but the wire 12 is not towed. That is, while the handle lever 11A is rotated at an angle within the predetermined angle θ, the handle lever 11A exhibits the door opening function expected even in the conventional door.

On the other hand, as shown in FIG. 3C, when the handle lever 11A is further rotated to, for example, about 60 °, the wire 12 is pulled by the slider 22 and the tension is transmitted to the operating device 30 as power.
When the handle lever 11A is released in this state, the latch bolt 17 and the slider 22 return to the natural state due to the restoring force of the springs 31 and 32.

Next, an example of the operating device 30 will be described with reference to FIGS. 4A and 4B.
4 (A) is an external view of the operating device 30, and FIG. 4 (B) is a cross-sectional view of the operating device 30 of FIG. 4 (A). However, in FIG. 4A, the outer peripheral surface of the cylinder 38 is represented by a broken line so that the guide teeth 39 of the cylinder 38 of the operating device 30 can be clearly shown.
The actuating device 30 is configured such that, for example, the abutting shaft (butting member) 19 and the cylinder spring 41 are housed in the cylinder 38.

The end ball 12b of the wire 12 is connected to the upper end of the abutting shaft 19. When pulled by the wire 12, the abutting shaft 19 moves upward in the cylinder 38 against the restoring force of the coiled cylinder spring 41.
On the other hand, when the traction force of the wire 12 is lost, the abutting shaft 19 moves downward in the cylinder 38 due to the restoring force and its own weight of the cylinder spring 41 connected to the upper end. The lower end of the abutting shaft 19 projects toward the floor surface 50 from the support plate 42 that supports the cylinder 38 at the lower end. The rubber pad 43 provided at the lower end of the abutting shaft 19 causes friction with the floor surface 50 to keep the door 100 in an open state.

By the way, guide teeth 39 are provided on the inner peripheral surface side of the cylinder 38. The guide tooth 39 is a groove or a protrusion for guiding the circumferential tooth 44 provided on the abdomen of the abutting shaft 19.
The guide tooth 39 is composed of an upper guide tooth 39a and a lower guide tooth 39b. The guide teeth 39 have convex portions (upper convex portion 46, lower convex portion 47) having a slope 46a and a vertical surface 46b extending in the vertical direction from the apex of the slope 46a on both the upper and lower sides, and are like saw teeth while facing each other vertically. For example, four cylinders 38 are arranged in the circumferential direction. The vertical faces 46b and 47b are aligned in a reciprocating manner so as to face the clockwise side or the counterclockwise side of the convex portions 46 and 47.

Further, the vertices of the convex portions 46 and 47 facing each other are offset by half of the convex portions in a reciprocating manner, and the extension lines of the vertical faces 46b and 47b of each other are in the middle of the slopes 46a and 47a of the convex portions 46 and 47 facing each other. Be placed. Further, the lower guide teeth 39b are provided with rectangular stopper grooves 49 at every 471 lower convex portions, that is, at two locations on the periphery so as to extend the vertical surface 47b toward the floor surface 50 side.
Further, the circumferential tooth 44 has a shape and a size that can be in contact with each side of the guide teeth 39a and 39b in order, such as a trapezoid or a circle having a lower base 44a along the vertical direction.

Next, the operation of the operating device 30 configured in this way will be described with reference to FIGS. 5 (A) to 5 (H) and FIGS. 6 (A) to 6 (F).
5 (A) to 5 (F) show the procedure of the lock-on operation, and the procedure from FIG. 5 (G) to returning to FIG. 5 (A) shows the procedure of the unlock operation.
6 (A) to 6 (C) are diagrams showing the interlocking of the operating device 20 and the operating device 30 in the lock-on operation.
6 (D) to 6 (G) are diagrams showing the interlocking of the operating device 20 and the operating device 30 in the unlocking operation.

[Lock-on operation (FIGS. 5 (A) to 5 (F), 6 (A) to 6 (C))]
First, when there is no traction from the wire 12, the circumferential tooth 44 is in contact with and pressed against the lower guide tooth 39b by the spring force of the cylinder spring 41 as shown in FIG. 5 (A) (FIG. 6 (FIG. 6). A)).
When the knob 11 is rotated by a predetermined angle θ or more and the wire 12 is pulled up in the operating device 20, the traction of the wire 12 shifts the peripheral teeth 44 vertically upward (FIG. 6). (B)).

Even after the peripheral tooth 44 comes into contact with the upper guide tooth 39a due to this shift, the peripheral tooth 44 receives an upward pulling force and tries to shift upward.
In response to this pulling force, the circumferential tooth 44 slides on the slope 46a of the upper convex portion 46 and orbits together with the abutting shaft 19 as shown in FIG. 5C.
Then, when the knob 11 is returned to the natural posture, as shown in FIG. 5D, the traction of the wire 12 is lost and the circumferential tooth 44 is vertically shifted toward the lower guide tooth 39b by the spring force of the cylinder spring 41. (Fig. 6 (C)).

Then, even after the contact with the lower guide tooth 39b, the abutment shaft 19 slides along the slope 46a of the lower convex portion 47 in order to receive the spring force and try to shift downward.
Then, the peripheral tooth 44 falls into the stopper groove 49 at the tip of the slope 46a as shown in FIG. 5 (E).
When the circumferential tooth 44 is fitted into the stopper groove 49 as shown in FIG. 5 (F), the rubber pad 43 at the tip of the abutting shaft 19 is abutted against the floor surface 50 to stop the door 100 on the spot. ..
Even when the peripheral teeth 44 are fitted into the bottom of the stopper groove 49 as shown in FIG. 5 (F), the spring force of the cylinder spring 41 acts on the peripheral teeth 44, so that the state of protrusion to the floor surface 50 is maintained.

[Unlocking operation (from FIG. 5 (G) to FIG. 5 (A), FIGS. 6 (D) to 6 (F)]]
Next, the unlocking operation will be described.
From the lock-on state of FIG. 5 (F) (FIG. 6 (D)), when the knob 11 is rotated by a predetermined angle θ or more, the wire 12 is pulled in the operating device 20. Due to the tension of the wire 12, as shown in FIG. 5 (G), the peripheral tooth 44 shifts upward together with the abutting shaft 19 in the vertical direction and comes out of the stopper groove 49, and the abutting shaft 19 enters the operating device 30. It is pulled up (Fig. 6 (E)). The circumferential tooth 44 shifted upward in the vertical direction comes into contact with the slope 46a of the upper guide tooth 39a. Since the wire 12 still pulls the abutting shaft 19, as shown in FIG. 5H, the peripheral tooth 44 rotates together with the abutting shaft 19 so as to slide on the slope 46a.

Then, when the knob 11 is returned to the natural posture, the traction force of the wire 12 disappears (FIG. 6 (F)). Therefore, the tension of the cylinder spring 41 returns to the state shown in FIG. 5 (A) in which the circumferential tooth 44 is pressed against the lower guide tooth 39b.

Next, a modified example of the application mode of the operating device 30A according to the first embodiment will be described with reference to FIGS. 7 and 8.
FIG. 7 is a diagram in which the operating device 30A according to the first embodiment is applied to a hinged door as a latch.
In FIG. 7, the wire 12 and the operating device 30A are embedded inside the door 100A, but they are shown by solid lines as appropriate in order to give priority to the legibility of the drawing.
When the operating device 30A is used as a bar, a bar 51 is provided on the wall surface to which the door 100A is attached, as shown in FIG.
Then, the actuating device 30A is built in the door 100A so that the abutting shaft 19 fits into the latch hole 51. The installation position of the bar 51 and the operating device 30A may be any of the upper, lower, left and right sides of the door 100A. By combining the pulley 53, the operating direction of the wire 12 can be freely designed.

Further, FIG. 8 is a diagram in which the operating device 30A according to the first embodiment is applied to the sliding door 100B as a latch.
When the operating device 30A is applied to the sliding door 100B, the operating device 20A may be provided separately from the pull tab 52. For example, as shown in FIG. 8, a cylindrical operating device 20A is provided near the pull tab 52. In such an operating device 20A, both side surfaces of the circle are arranged on the same surface as the surface of the sliding door 100B. Both side surfaces of this circle are engraved to form a thumb turn 54. The body of the operating device 20A is provided with a notch 55 that reaches the vicinity of the rotation center axis C.

Then, the end portion of the wire 12A is inserted through the notch 55 and fixed in the vicinity of the rotation center axis C. With such a structure, the wire 12 extends vertically from the body surface of the operating device 20 along the notch 55 from the rotation center axis C under the weight of the operating device 20A. When the thumb turn 54 is picked up and rotated, the wire 12A is pulled upward because it is wound around the body of the operating device 20A by the amount of this rotation.
When the bar 51 is provided on the floor surface 50 as shown in FIG. 8, the operating device 30A can be exteriorized without being built in the door 100A.

As described above, according to the stopper 10 according to the first embodiment, the door 100 can be temporarily fixed at a desired position only by operating the knob.
Further, according to the door 100 according to the first embodiment, it is possible to give a simple and orderly aesthetic appearance and prevent the accessory parts necessary for temporarily fixing the door 100 from being lost.

(Second Embodiment)
9 (A) and 9 (B) are schematic configuration diagrams of the stopper 10a according to the second embodiment.
FIG. 9A shows a state when the door is closed, and FIG. 9B shows a state when the abutting shaft 19 is projected.

In the second embodiment, the peripheral teeth 44 and the guide teeth 39 (39a, 39b) shown in FIG. 4 and the like are not always essential.
In the stopper 10a according to the second embodiment, as shown in FIGS. 9A and 9B, a pull-in member 56 is provided in the casing 23. The pull-in member 56 is, for example, a coil spring installed between the edge portion of the casing 23 and the slider 22a so as to come into contact with the slider 22a. The pull-in member 56 elastically contacts the slider 22a and applies an elastic force to the slider 22a in a direction of pulling the wire 12 into the casing 23.

That is, the pull-in member 56 functions as a second elastic portion that attempts to cancel the elastic force of the cylinder spring (first elastic portion) 41a of the first embodiment.
In other words, the pull-in member 56 has a function of pulling up the wire 12 via the slider 22a to weaken the elastic force for projecting the abutting shaft 19 from the cylinder 38a by the cylinder spring 41a.
As a result, when the handle lever 11A is not rotating as shown in FIG. 9A, the pushing force of the cylinder spring 41a is weakened by the pulling member 56, so that the abutting shaft 19 does not protrude.

Further, in the second embodiment, as shown in FIG. 9B, the arm portion 11b for the slider abuts on the upper side side of the retracting member 56 by rotation.
That is, the handle lever 11A rotates greatly, and the arm portion 11b for the slider pushes down the slider 22a against the elastic force of the pull-in member 56. When the slider 22a is pushed down, the tension of the wire 12 is weakened, and the pushing force of the cylinder spring 41a offset by the pulling member 56 is applied to the abutting shaft 19. Then, the abutting shaft 19 projects toward the floor surface @ and fixes the door 100 at an arbitrary opening angle.

The arrangement position of the pull-in member 56 is not limited to the example of contacting the lower side of the casing 23 as shown in FIG. 9B. It may be arranged anywhere in the casing 23 as long as the elastic force of the cylinder spring 41a can be offset. For example, the retracting member 56 may be set with respect to the slider 22a on the same side as the knob internal mechanism 11B in a state of being extended from the natural length. In this case as well, the pulling member 56 can apply an elastic force for pulling the wire 12 into the casing 23 to the slider 22a. Further, the slider 22a may slide in any direction as long as the wire 12 is pulled into the casing 23.

Further, in FIGS. 9A and 9B, the latch bolt support portion 21 is changed to a ring-shaped, plate-shaped, or rod-shaped engaging member provided on the latch shaft 17a. Further, the shape of the arm portion 11a for the latch bolt is also slightly changed according to this change. As described above, the shapes of the latch bolt arm portion 11a and the latch bolt support portion 21 are variously selected depending on the mutual arrangement relationship.

Further, FIG. 10 is a diagram showing a state of the stopper 10a according to the second embodiment when the door is opened.
When the handle lever 11A is rotated at a predetermined angle θ or less as in the first embodiment, the slider arm portion 11b does not come into contact with the slider 22a as shown in FIG.
Therefore, within the predetermined angle θ, the latch bolt 17 functions as a normal door that is only pulled into the casing 23.

Since the second embodiment has the same configuration as the first embodiment except that the retracting member 56 is used for the reciprocating movement of the abutting shaft 19 instead of the mechanisms of the circumferential teeth 44 and the guide teeth 39, they overlap. The description to be made is omitted. Further, also in the drawings, the description thereof will be omitted by assigning the same reference numerals to the corresponding configurations.

As described above, according to the stopper 10a according to the second embodiment, the same effect as that of the first embodiment can be obtained with a simple structure having no guide teeth 39.

Although embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention.
The embodiment can be implemented in various other forms, and various omissions, replacements, changes, and combinations can be made without departing from the gist of the invention. The embodiments and variations thereof are included in the scope of the invention described in the claims and the equivalent scope thereof, as are included in the scope and gist of the invention.

For example, the door is temporarily fixed by bringing the stopper into close contact with the floor surface, but the protrusion of the stopper may be the ceiling or the side wall.
Further, although the abutting shaft has been described as an example of the abutting member, the abutting member may have any shape as long as it can prevent the door from closing due to contact with the floor surface.
Further, as described above, the application target of the stopper is not limited to the door.
