Description

  The present invention relates to an arm stopper for stopping a door at a predetermined position with respect to a frame.

  Conventionally, in the case of a door consisting of a frame and a door, a hinge or a pivot hinge has been used as a means for hanging the door freely openable and closable in the frame, and is usually arranged at a position where the axis is taken out of the door surface The taken-out hanging is the best condition for opening and closing the door, and the door can be opened up to 180 degrees as it is. However, in cases where the door can only be opened up to about 90 degrees, there is no mechanism to stop at a fixed angle on the normal hinge or pivot hinge itself, so a separate stop member is provided to prevent the door from hitting the wall. Will be needed.

  Members that have been frequently used in the past to stop the door are broadly classified into door stoppers and arm stoppers. A great many types and mechanisms have been proposed for door stoppers, but basically the door is stopped at that position by hitting the door surface to a receiving member fixed to the floor or wall surface It has become. In the simplest configuration, as shown in Japanese Patent Application Laid-Open No. 2001-279997, a door stopper is fixed to the floor at a position where the door is opened by about 80 degrees, and when the door is opened, the lower part of the door hits the door stopper and stops. It is supposed to. In general, a soft abutment member such as rubber is provided at the tip of the door stopper in order to reduce the impact at the time of stopping. Also, a mechanism is required for the door stopper to keep the door at the stopped position, a member such as a hook is provided on the door side, and a protrusion is also provided for the door stopper itself, A configuration in which a door is held by hooking a hook on a projection is often used.

  Here, in recent years, the demand for barrier-free in houses and the like has become important, and in the above-mentioned Japanese Patent Application Laid-Open No. 2001-279997, the door stopper itself becomes a protrusion from the floor, which is not preferable. It has come to be judged. Therefore, a floor device having a metal flap that swings up and down on the floor surface, as described in JP-A-2004-84202 and JP-A-2018-31194, is disposed, and a floor device is provided at a position below the door. A door stopper having a mechanism in which a flap is attracted and lifted by a magnet when the main body device in which the portion and the magnet are arranged and approaches the stop position of the door and is brought into contact with a receiving portion of the main body device, and is recently used. Is often used. The greatest feature of this configuration is that the floor device itself has a plate-like flap as a main member, and can be formed in a very thin shape as a whole, and is considered to be excellent from the viewpoint of barrier-free. Also, there have been proposed many devices that also have a mechanism for holding a door at a stop position.

  However, it is important that the floor device mounted on the floor and the main unit mounted on the door must be properly positioned relative to each other, especially since the operation of lifting the flap by magnetic force is delicate. Also, it is difficult to set the positions of the two and adjust the height direction. Further, even if the floor device has a thin shape, even the thinnest device is limited to about 4 mm, and a toe may be caught when passing. Further, it is said that it is not preferable that the flap moves up and down with the suction force of the vacuum cleaner during cleaning. Also, it has been pointed out that the construction itself in which the floor device must be fixed to the floor surface with screws or the like is not preferable.The most common case is a carpet floor with long hairs, and the carpet is installed on the floor device. It takes a lot of time and labor to cut out and mount the auxiliary plate and the like at the same height. Furthermore, since the tip of the flap is in contact with the receiving portion, the impact at that time is large, and it is also desirable to have a mechanism that absorbs the impact at the time of stopping when the door is opened and the like.

  Also, in terms of design in size and design, the main unit is often mounted with a surface below the door at the side where the door opens, and it is necessary to incorporate a magnet in the main unit. The point is that it is difficult to be compact in the pod thickness. In addition, it is required that the magnetic force be stronger.If a ferrite magnet that is inexpensive but has a weak magnetic force is used, the size tends to increase in order to obtain the required magnetic force, and a neodymium magnet with a small size and a strong magnetic force is expensive. However, it is assumed that it is difficult as an option to use either. In practice, compact designs using neodymium magnets are often used with emphasis on design, but doing so increases the cost burden, and if possible, a type that does not use magnets is desired. . Therefore, a configuration as disclosed in Japanese Patent Application Laid-Open No. 2015-196988 is also reported. However, this configuration is considered to be insufficient in that point because the thickness of the floor device becomes large. In order to further improve the design, there is a configuration in which the main body device is carved in the lower part of the front end of the door, as reported in Japanese Patent Application Laid-Open No. 2005-9151. There is concern about the strength of the remaining surface of the door, and it is not easy to make the main unit thinner.

  Further, as another configuration for stopping the door, there is an arm stopper conventionally disposed on the upper portion and the upper frame of the door. This arm stopper has a configuration in which two arms overlap and extend and contract as reported in Japanese Patent Application Laid-Open No. 2010-285858, with the tip of one arm at the upper frame and the tip of the other arm at the top of the door. When the door is mounted and the door is closed, the two are most overlapped and contracted, and the two arms extend as the door is opened, and the opening operation of the door stops when the door is completely extended. In addition, a rail and an arm are mounted on the upper frame and the upper part of the door using a rail and an arm as reported in JP-A-2010-1684, and a slide pin arranged on the arm moves within the rail. There is also used a type in which the opening of the door is stopped when the slide pin moves to the stop position.

However, in both cases, the relatively long arms and rails are exposed at the upper part of the door in a state where they are exposed, which is not preferable in terms of design, and the frequency of use is low for interior doors where design is most important. Is assumed. It is also possible to place an arm stopper between the upper surface of the door and the inner surface of the upper frame, but in such a case, the gap between the upper portion of the door and the inner surface of the upper frame becomes extremely large, and ordinary wooden In most indoor doors, this gap is set to be very small, and it is assumed that it will be impossible to fit the door. Further, at present, little consideration is given to shock absorption when both arms are fully extended at the time of stop.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a first object of the present invention is to provide a door arm stopper having a new structure excellent in design and a structure for absorbing a shock at a stop. The second purpose is to have both.

  In the present invention, the following technical means are provided to achieve the above object. First, a substantially L-shaped frame-side base member having a vertical frame mounting surface, an arm mounting horizontal surface, an arm stop piece, and an arm rotation axis, a plate-shaped slide pin at one end and a rotation shaft insertion hole at the other end were provided. A long arm and a door-side plate having a long hole and an inclined contact portion are provided. Then, the frame-side base member is attached to the lower part of the hanging side of the inner surface of the vertical frame, and the door-side plate is attached to the lower part of the door. Next, the slide pin is held in a state of being inserted into the long hole of the door-side plate, and further, the arm is mounted so that the arm can be rotated horizontally with respect to a horizontal plane to which the arm is attached by the arm rotation axis. At this time, the slide pin is made movable in the long hole of the door-side plate. Then, in the closed state of the door, the arm is disposed at a lower position within the thickness of the door, and the arm is rotated with respect to the arm rotation axis while the slide pin moves in the elongated hole of the door side plate with the opening operation. Is obtained.

Also, the arm stop piece is formed in a state of standing upright from a position on the near side of the horizontal surface of the arm mounting of the frame-side base member, and the arm rotation shaft is disposed at a position on the far side of the horizontal surface of the arm mounting so that the distance between the two is minimized. Set apart. Then, the arm is mounted on the arm rotation axis with the arm mounted on a horizontal plane. Then, at a stage where the door is opened to a predetermined angle, the arm side stops abutting on the arm side piece to stop the rotation operation of the arm. And the long hole of the door side plate is set in the direction parallel to the surface of the door, and the arm and the long hole are also almost parallel, so the rotation of the door should be stopped almost simultaneously when the arm stops. Can be. The predetermined angle is not particularly limited, but is set to stop at a position opened by about 80 degrees similarly to a door stopper mounted on a normal floor or an arm stopper mounted on the upper part of a door. Good to keep.

Next, the door-side plate is mounted in close contact with the lower surface of the door, and the inclined contact portion is formed to protrude further downward from the door-side plate. Although the slide pin is inserted into the long hole of the door-side plate, it is preferable that the shape of the slide pin is formed with a flange so that it does not fall off, and the shape of the long hole is also stepped. Therefore, the arm is arranged so as to face the door-side plate, and the arm faces the lower surface of the door-side plate in a state where the arm rides on the horizontal surface where the arm of the frame-side base member is attached. Is set to be horizontal. When the door is opened from this state, the door itself rotates around the hinge axis position, but the arm rotates around the arm rotation axis while the slide pin moves in the elongated hole, and the arm The operation is such that the side surface of the arm approaches the inclined contact portion while the angle of the arm gradually changes. Therefore, it is preferable to set the position of the inclined contact portion so that the side surface of the arm contacts the inclined contact portion at the position of the arm when the door is opened at about 80 degrees to be stopped. Then, the door can be stopped at that position.

  Also, as described above, since the slide pin mounted on the arm moves in the long hole of the door-side plate when the door is opened, it is preferable that the long hole is set to end at a position of about 80 degrees to be stopped. Good. Then, at the stage when the door is opened, the slide pin comes into contact with the end of the long hole, and the door can be stopped at that position. In addition, the stopping operation in which the arm stop piece of the frame-side base member and the arm side contact with each other, the stopping operation in which the inclined contact portion of the door-side plate and the arm side contact with each other, and the slide pin mounted on the arm is connected to the door side By simultaneously performing any two operations or all three operations of the stop operation in contact with the end of the long hole of the plate, the door can be stopped more reliably.

  However, in a case where the door is strongly opened with only the above-mentioned configuration in which the door is stopped, an operation of contacting the stop position with an impact occurs. Therefore, it is assumed that applying a resistance or load during the operation of the slide pin moving in the long hole of the door-side plate will reduce the door opening speed and reduce the impact at the time of stop. You. As a means, the inner surface of the elongated hole of the door-side plate is formed as a friction surface, and when the slide pin moves in the elongated hole of the door-side plate, the frictional surface and the slide pin rub against each other to provide a resistance. It is easy to make a configuration to set it to occur.

  Further, as a more specific configuration, first, a block member having a concave long hole is integrated with the door-side plate, and a slide pin extending upward is inserted into the concave long hole of the block member through the long hole of the door-side plate. It is good to be constituted so that it may move. A wide friction member is provided in a predetermined range of the concave long hole, and a setting is made so that a deceleration operation can be obtained when the door is opened with a resistance force caused by an operation of rubbing the slide pin and the friction member from a predetermined front angle of the stop position of the door. By doing so, it is possible to greatly reduce the impact at the time of stopping. Further, a spring member is provided and used in combination with the friction member, and a greater deceleration operation can be obtained by a resistance force caused by the friction member pressed by the spring member from the stop position of the door and pressed against the slide pin by a predetermined angle. . In addition, since the deceleration operation due to the friction is to stop the slide pin from moving at that position, it also has a mechanism for stopping and holding the door at a position of about 80 degrees.

  Further, as another configuration for further ensuring the deceleration operation described above, a block member provided with a concave long hole and a portion for mounting a linear motion damper on a door-side plate is integrated, and a slide pin extending upward is provided on the door side. It is preferable to be configured to be inserted into the concave long hole of the block member and move through the long hole of the plate. Then, a linear motion damper configured to generate a load when the rod bar sinks is provided, and the linear motion damper is mounted on the block member in a state where the rod bar protrudes into the concave elongated hole. Then, the slide pin comes into contact with the rod bar of the linear motion damper from a predetermined angle before the stop position of the door, and a deceleration operation is obtained until the door stops. This linear motion damper generates a larger load when the rod is pushed in at a stretch with a strong force, and is therefore expected to be more effective when the door is suddenly opened.

  Further, a configuration in which the friction member is pressed against the concave long hole of the block member by the spring member in the direction of the inner surface of the long hole, and a configuration in which the linear motion damper is mounted on the block member so that the rod rod projects into the concave long hole. When both are provided at the same time, the resistance force caused by the frictional action of the friction member pressed by the slide pin and the spring member from the predetermined front angle of the stop position of the door, and the slide pin abuts on the rod rod of the linear motion damper and sinks. In this case, both the load and the load generated at the time can be obtained, and a more effective door deceleration operation can be performed.

  When the door is opened to a predetermined angle, the arm stop piece of the frame-side base member abuts on the arm side near the arm rotation axis, so that the door can be stopped.

  When the door is opened to a predetermined angle, the arm side surface comes into contact with the inclined contact portion formed to protrude further downward from the door-side plate, so that the door can be stopped.

  When the door is opened to a predetermined angle, the slide pin mounted on the arm comes into contact with the end of the long hole of the door-side plate, so that the door can be stopped.

  A stop operation in which the arm stop piece of the frame-side base member contacts the arm side surface, a stop operation in which the slant contact portion of the door-side plate contacts the arm side surface, and a slide pin mounted on the arm has a long hole in the door-side plate. By simultaneously performing any two or all three of the stop operations that come into contact with the ends, it becomes possible to more reliably stop the door when it is opened to a predetermined angle.

  By forming the inner surface of the elongated hole of the door side plate in a predetermined range as a friction surface, the friction surface and the slide pin rub against each other from a predetermined angle before the stop position of the door. A deceleration operation can be obtained.

By integrating a block member having a concave long hole in the door side plate and providing a friction member or a spring member in a predetermined range of the concave long hole, the slide pin and the friction member rub against each other from a predetermined angle before the stop position of the door. An operation is performed, and a deceleration operation of the door can be obtained by the resistance. Further, the door can be held at the stop position by the frictional force.

The door is stopped by integrating a block member having a concave long hole and a part to which a linear motion damper is attached to the door side plate, and installing a linear motion damper that generates a load when the rod bar is retracted. The slide pin comes into contact with the rod bar of the linear motion damper from a predetermined front angle of the position, and the load at the time when the rod bar sinks can obtain the deceleration operation of the door.

  In a configuration in which a friction member or a spring member is provided in the concave long hole of the block member, and a linear motion damper configured to generate a load when the rod bar is retracted is provided, from a predetermined front angle of the stop position of the door, It is possible to obtain the deceleration operation of the door by both the resistance force caused by the operation of friction between the friction member pressed by the slide pin and the spring member and the load generated when the slide pin abuts on the rod rod of the linear motion damper and sinks. it can.

  The frame-side base member is located below the inner surface of the vertical frame, and the door-side plate and arm are mounted at the lower position of the door's thick part, so they are both hidden and difficult to see, and the entire door is Does not affect design.

  Since the arm stopper as a whole is configured to have a thickness such that the arm mounting horizontal surface of the frame-side base member overlaps the arm and the door-side plate, the arm stopper can be sufficiently accommodated between the floor surface and the door lower surface.

The number of parts is extremely small in the configuration with only the stop mechanism including the frame-side base member, the door-side plate, and the arm. Can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an arm stopper according to the present invention. The arm stopper includes a substantially L-shaped frame-side base member 1, an elongated plate-like arm 6, and a plate-like rectangular door-side plate 9 as main members. . FIG. 2 is an exploded perspective view of the frame side base member 1, which has a vertical frame mounting surface 2 provided with a mounting hole 20, an arm mounting horizontal surface 3, an arm stop piece 4, and an arm rotating shaft 5. The arm stop piece 4 is formed upright at a position on the near side of the horizontal plane 3 on which the arm is mounted, and an arm rotating shaft 5 is provided at a position on the far side of the horizontal plane 3 on which the arm is attached so as to be detachable. Here, the means for mounting the arm rotation shaft 5 is not limited, but in the embodiment, a male screw portion is provided on the arm rotation shaft 5, a female screw portion is provided on the arm mounting horizontal surface 3, and a cross hole portion is provided on the upper surface of the arm rotation shaft 5. It is preferable to provide such a structure that it can be attached and detached with a driver or the like.

  FIG. 3 is a perspective view of the arm 6, in which a long plate-shaped slide pin 7 with a collar is mounted at one end and a rotary shaft insertion hole 8 is provided at the other end. Next, FIG. 4 is a perspective view of the door-side plate 9, which has a rectangular plate shape and has a stepped long hole 10 and an inclined contact portion 11, and mounting holes 20 are formed at four corners. At this time, the inclined contact portion 11 is formed so as to protrude further downward from the lower surface of the door-side plate 9. Then, as shown in FIG. 1, the shaft portion of the slide pin 7 is inserted into the narrow side of the step of the long hole 10 of the door-side plate 9, and the flange of the slide pin 7 is inserted into the wide portion of the step of the long hole 10. In this state, the slide pin 7 is fixed to the arm via a washer 21 having a low coefficient of friction, such as resin, with the lower surface of the door-side plate 9 and the arm 6 facing each other. Then, the slide pin 7 can be smoothly moved in the long hole 10 without falling out of the long hole 10. Then, the male screw portion of the arm rotary shaft 5 is screwed into the female screw portion of the arm mounting horizontal surface 3 with the male screw portion of the arm rotary shaft 5 penetrating the rotary shaft insertion hole 8 with the rotary shaft insertion hole 8 side of the arm 6 placed on the arm mounting horizontal surface 3. Then, assemble in a rotatable state. At this time, similarly, if the washer 21 made of resin or the like is appropriately incorporated into the operation surface of the arm rotation shaft 5, the durability can be increased.

  Here, when attaching the arm stopper of the present invention to an actual door, the arm rotation shaft 5 is removed in advance, and the frame-side base member 1 and the arm 6 are divided into a state in which the arm 6 is assembled to the door-side plate 9. deep. Then, the frame-side base member 1 is attached to a lower portion of the hanging side of the vertical frame inner surface 24 through a mounting hole 20 of the vertical frame mounting surface 2 with a wood screw or the like. Further, the door-side plate 9 with the arm 6 attached to the door lower surface 23 is similarly attached to the door lower surface 23 with a wood screw through the mounting hole 20 in a state of being in close contact with the door lower surface 23. In this state, the door 26 is suspended from the hinge 22 or the like in the frame, and then the arm 6 is mounted on the arm rotation shaft 5 so that the arm 6 can be rotated horizontally with respect to the horizontal surface 3 on which the arm is mounted. FIG. 5 is a front view showing only the lower part of the door in that state, and FIG. 6 is a top view in the same state, and both show a state in which the door 26 is closed. As a result, as shown in FIG. 5, the inclined contact portion 11 projects further downward from the lower surface of the door-side plate 9, and the arm 6 rests on the arm mounting horizontal surface 3 of the frame-side base member 1. Therefore, it is preferable that the arm 6 is set to be in a horizontal state in this state. In addition, in order to clarify the position and direction with respect to the door 26, the axis side of the hinge 22 in FIG.

  Then, the entire height of the arm stopper can be made extremely thin by a configuration in which the arm 6 rides on the horizontal surface 3 for mounting the arm of the frame-side base member 1 and faces the door-side plate 9 only, and as shown in FIG. And the door lower surface 23. It is also possible to dig the thickness of the door side plate 9 into the door lower surface 23 and mount it, and it is also possible to cope with the case where the floor surface 27 and the door lower surface 23 are narrow. In FIG. 5, the vertical frame mounting surface 2 of the frame-side base member 1 is shown as being mounted on the vertical frame inner surface 24 with a surface, but only the thickness of the vertical frame mounting surface 2 is provided on the vertical frame inner surface 24. It is also possible to dig and arrange it, and it is possible to secure a wider gap between the door 26 on the hanging side and the inner surface 24 of the vertical frame.

  When the door 26 is closed as shown in FIG. 6, the frame-side base member 1, the door-side plate 9 and the arm 6 are arranged at lower positions within the thickness of the door 26, that is, the entire arm stopper is It is hidden at the bottom of. Therefore, it is almost invisible from a line of sight from a normal standing position, and it is assumed that the door as a whole is very excellent in design. Therefore, as shown in FIG. 6, the arm stop piece 4 at a position in front of the horizontal surface 3 of the arm is formed at a position as far as possible so as not to protrude from the front of the door 26, and the arm rotation shaft 5 arranged on the back side is Is preferably formed at a position very close to the back of the camera, and the distance between them is set as far as possible. 6, 7, 8, and 14, the arm stopper itself is located below the door 26 and should be displayed as a dashed line because it is shown in a top view. Because it is difficult to understand because there are many overlaps, it is shown with a solid line.

  Next, in a configuration in which the stop position of the door 26 is set to about 80 degrees, the trajectory when the door 26 is opened from the closed state shown in FIG. The position at about 80 degrees is shown in FIG. In the closed state, the arm side surface 13 and the inclined contact portion 11 of the door-side plate 9 are separated from each other, and at the same time, the arm side surface 13 and the arm stop piece 4 of the frame-side base member 1 that are close to the arm rotation shaft 5 are also moved. It is far away. When the door 26 is gradually opened from this state, the door 26 rotates about the axis of the hinge 22. However, since the arm 6 rotates about the arm rotation axis 5 and the axis of the hinge 22 and the position of the arm rotation axis 5 are away from each other in the front and back directions, the slide pin 7 is about 20 degrees, about 40 degrees, As the door is opened at about 60 degrees, the door-side plate 9 moves in the long hole 10 in the direction of the long hole end 12. The arm side surface 13 also has a locus gradually approaching the inclined contact portion 11. Further, the arm side surface 13 at a position close to the arm rotation shaft 5 also has a locus gradually approaching the arm stop piece 4.

  At the stage when the door 26 is opened by about 80 degrees to stop, the arm side surface 13 and the inclined contact portion 11 come into contact with each other, and at the same time, the arm side surface 13 near the arm rotation shaft 5 and the arm stop piece 4 come into contact with each other. Further, it is preferable that the slide pin 7 is set so as to abut against the end portion 12 of the elongated hole, and an operation of stopping the door 26 is obtained by each of the three abutting operations. Here, FIG. 8 shows a virtual position of the door 26 and the arm 6 when the door 26 is forcibly opened to about 90 degrees from the stop position of the door 26 set to about 80 degrees. As for the inclined contact portion 11, both of them overlap with the hatched portion, and both the arm side surface 13 and the arm stop piece 4 near the arm rotation shaft 5 also overlap with the hatched portion. 7 and the end portion 12 of the long hole of the door-side plate 9 also overlap with the hatched portion. However, since the actual operations do not overlap, it can be seen that the three operations can more reliably stop the door 26 at about 80 degrees.

  Also in the opening range of the door 26 in FIG. 7, the arm 6 moves only slightly at the lower position within the thickness of the door 26 except for the position approaching about 80 degrees, and during that time, the lower surface of the door 26 Since it is not exposed from the door 23, there is no influence on the design of the entire door even during the opening operation, and there is no danger such as finger scissors due to the arm 6 and the door surface.

  Here, it is possible to stop the door 26 by each of the three contact operations described above, but there is a difference in the direction and degree of impact at each contact. First, in the stopping operation in the contact between the arm side surface 13 and the arm stop piece 4 at a position close to the arm rotation shaft 5, the back side of the vertical frame mounting surface 2 of the frame side base member 1 is to be peeled off from the vertical frame inner surface 24. Since the force is applied in the direction described below and the contact position between the arm rotation shaft 5 and the arm rotation shaft 5 is close, the force is assumed to be extremely large. Therefore, it is assumed that it is necessary to use a longer wood screw or the like to be fixed to the inner surface 24 of the vertical frame, and to fix it more firmly through the mounting hole 20. Further, in the stop operation in the contact between the arm side surface 13 and the inclined contact portion 11, a force is applied in the door tip direction to the axis of the hinge 22 together with a force for bending the arm 6 in the horizontal direction. Therefore, it is preferable to increase the surface strength of the blade fixed to the vertical frame 25 of the hinge 22. As for the stop operation when the slide pin 7 comes into contact with the long hole end portion 12 of the door-side plate 9, a force is applied to pull the door 26 in the back direction with the door 26 itself opened at about 80 degrees. Assuming that the slide pin 7 has high strength, a force is applied to the hinges 22 attached to the door 26, so that the surface strength of the hinges 22 should be increased.

  As described above, the stop operation of the door 26 can be obtained. However, with the above configuration alone, when the door 26 is left open, the stop operation is suddenly stopped with a strong impact. Further, there is a concern that the door 26 may rebound due to the impact at the time of the stop. Therefore, a configuration is desired in which the opening speed of the door 26 is reduced from a predetermined angle before the stop position to reduce the impact at the time of stop. In this deceleration operation, it is assumed that it is effective to use the operation in which the slide pin 7 moves in the long hole 10 of the door-side plate 9. In its simplest configuration, a predetermined range of the inner surface of the long hole 10 of the door-side plate 9 is set slightly narrower to form the friction surface as it is, and the slide pin 7 moves in the long hole 10 of the door-side plate 9. At this time, if friction is generated in a state where the friction surface and the slide pin 7 are strongly rubbed, the door 26 can be decelerated by the resistance. Further, the predetermined angle at which the deceleration operation is started is not particularly limited, but it is preferable that the opening and closing is not heavy during normal traffic, so it is assumed that the configuration in which the opening angle of the door 26 is decelerated from about 60 degrees is good. Is done. Then, even when the door 26 is opened, it is possible to completely stop the door at the position of about 80 degrees while reducing the speed from the position of about 60 degrees.

  However, in the above-described configuration of only the friction surface, it is considered that the deceleration amount is not sufficient in any case such as when the heavy door is strongly opened, and it is assumed that a configuration that can obtain a stronger resistance is required. . Therefore, as a specific configuration, as shown in FIG. 9, a block member 16 having a concave long hole 17 is provided, and the long hole 10 and the concave long hole 17 of the door-side plate 9 are integrated in a state of being overlapped. . It is preferable to provide a vertically wide friction member 14 formed of a resin or the like which is not easily worn, at the end of the concave long hole 17. As an example of the friction member 14, a material having low hardness such as urethane having a fine uneven surface 15 on the surface as shown in FIG. 10 is excellent. It is good to arrange on the block member 16 so that it may be sandwiched between them. Further, a disc spring 18 as a spring member is further provided, and it is preferable to incorporate the disc spring 18 in such a manner that the uneven surface 15 of the friction member 14 is pushed inward. FIG. 11 is a top view of the block member 16 integrated with the door-side plate 9, wherein the width between the concave and convex surfaces 15 of the friction members 14 arranged in the concave long holes 17 is the same as that of the concave long holes 17. The width is set to be narrower than the width by the deflection of the disc spring 18.

  Then, as shown in FIG. 12, the slide pin 7 is formed in a shape that is further extended upward from the flange portion, and the diameter of the extended portion is set to a size that can be barely moved in the concave long hole 17. It is arranged in a state of being inserted into the concave long hole 17 of the member 16. FIG. 13 is a front view showing only the lower part of the door showing the state, in which only the block member 16 is dug from the door lower surface 23 to be built therein, and the door side plate 9 is imposed on the door lower surface 23 by imposition. I am wearing it. The friction member 14 and the disc spring 18 are arranged at the end of the concave long hole 17. Next, FIG. 14 is a trajectory diagram of the arm stopper due to the opening of the door 26 in the above-described configuration, in which the slide pin 7 reaches the narrow range sandwiched between the friction members 14 from the position where the opening angle is about 60 degrees. While being pressed by the spring 18, the deceleration operation is obtained by the resistance force caused by the rubbing with the uneven surface 15, and the operation of stopping the door 26 at about 80 degrees is obtained. Further, in the open state of about 80 degrees in FIG. 14, the slide pin 7 is sandwiched between the two friction members 14, so that the slide pin 7 can also have a stop holding function at this position. Although not shown, if a concave portion is formed on the uneven surface 15 at this stop position, it is easy to further increase the stop holding force by the slide pin 7 entering the concave portion.

  However, with the above configuration, a certain amount of deceleration can be obtained, but it is inevitable that there is a difference in deceleration between heavy doors and lightweight doors. In this case, the release operation becomes heavy at the stage of releasing from approximately 60 degrees to approximately 80 degrees, and it is assumed that there is still room for improvement in this regard. Therefore, as shown in FIG. 15, the block member 16 is further set to be longer in the lateral direction, and a portion for mounting the linear motion damper is provided, and the linear motion damper 19 is blocked in a state where the rod rod projects into the concave long hole 17. It is mounted on the member 16. The linear motion damper 19 used here has a configuration in which a load is generated when the rod bar is retracted. If the rod bar is pushed at a stretch with a strong force, a larger load is generated, and the rod bar is pushed with a weak force. In the unlikely event, a type that generates only a small load is superior. The slide pin 7 comes into contact with the rod of the linear motion damper 19 from about 60 degrees when the door 26 is opened, and the stroke of the linear motion damper 19 is completely lowered at the stop position at about 80 degrees. Should be set. Then, when the door 26 is suddenly opened, a large load is generated, and when the door 26 is slowly opened, a not so large load is generated, so that a more appropriate deceleration operation can be obtained.

However, in the configuration of FIG. 15, since there is no stop holding operation at about 80 degrees, both the configuration for obtaining the resistance by the friction member 14 shown in FIG. 9 and the configuration for obtaining the load by the linear motion damper 19 shown in FIG. It is assumed that the configuration as shown in FIG. FIG. 17 is a schematic cross-sectional view showing the operation by the movement of the slide pin 7 in the configuration of FIG. First, FIG. 17A shows a state in which the door 26 is closed. When the door 26 is opened and reaches a position of about 60 degrees, as shown in FIG. 17 and comes into contact with the friction member 14 and comes into contact with the distal end of the rod rod of the linear motion damper 19. When it is further opened, the slide pin 7 further moves as shown in FIG. 17 (c), and the friction member 14 is pushed in while compressing the disc spring 18 to generate a resistance force, and the rod rod of the linear motion damper 19 is moved. The load caused by the sinking operation is also obtained at the same time, and as a result, the effect of rapidly decelerating the door 26 is obtained. Therefore, it is assumed that this configuration is more effective when the heavy doors etc. are suddenly opened.However, in the case of operation at low speed where the doors are opened by hand even with lightweight doors, the load of the linear motion damper is Because it is so small, the operation does not become too heavy.

  In the above description, the block member 16 is arranged in a state dug from the door lower surface 23, and the door-side plate 9 is mounted on the door lower surface 23 by imposition. It takes time to dig 23. In order to attach the arm stopper and to hang the door 26 in this configuration, before hanging the door 26 to the frame, first, the door-side plate 9 with the arm 6 assembled is moved to the lower part of the door. The frame-side base member 1 is mounted in advance on the dug portion of the surface 23, and then the frame-side base member 1 is mounted on a lower position of the vertical frame 25. Then, the door 26 is suspended from the frame using the upper and lower hinges 22, and finally, the arm rotation shaft 5 is inserted into the rotation shaft insertion hole 8 of the arm 6, and the arm 6 is attached to the arm mounting horizontal surface 3 of the frame side base member 1. It is the procedure to assemble. Therefore, as a feature of this configuration, in order to improve the design of the entire door, it is important that the arm stopper itself is not exposed as much as possible, but the arm stopper cannot be attached after the door 26 is constructed. It has a configuration.

  Therefore, as shown in FIG. 18, the door-side plate 9 is set to have a wide shape protruding from the inner surface of the door 26 by a predetermined dimension, and the block member 16 having the concave long hole 17, the friction member 14, and the linear motion damper 19 is formed. The lower part 23 of the door was formed integrally with the protruding part, and only the inclined contact part 11 was formed, and the arm 6 was formed so as to be obliquely bent from the position of the slide pin 7. It is also possible to implement an imposition type that is mounted in the depth direction below the door. In the mounting procedure of the imposition type shown in FIG. 18, first, the arm 6 is further assembled on the door-side plate 9 in which the block member 16 is integrated, and both ends of the block member 16 are imposed at the lower position of the door 26. And fix with wood screws. At this time, the surface of the inclined contact portion 11 of the door-side plate 9 is brought into close contact with the door lower surface 23. Next, with the door 26 largely opened, the frame-side base member 1 is similarly fixed to a lower position of the vertical frame inner surface 24 with a wood screw or the like. Finally, by assembling the arm 6 to the frame-side base member 1 with the arm rotating shaft 5, the arm stopper can be easily attached to the door after construction by imposition.

  In the above description, the arm stopper is arranged at the lower position of the door 26. However, if the gap between the upper surface of the door 26 and the upper frame can be set large, it can be arranged at the upper part. An arm stopper with good design can be provided. Furthermore, it can be arranged on both the upper and lower sides of the door 26, so that a configuration for more reliably stopping the door 26 can be realized.
