A floor-side member (hereinafter, also simply referred to as a “floor-side member”) for a door stop according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. In this manual, "upward" and "top view" refer to the direction or position in a state where the floor-side member is installed on the floor. The floor-side member 10 is a catcher pin (impact pin), and includes a resin-made bumper 10A and a bumper holding table 10B. The buffer holding table 10B is formed by hollowing out a surface portion of a flat, substantially semi-conical body having a height of 10 mm or less into a buffer shape. A screw hole (not shown) is formed in the bottom portion 19b of the buffer accommodating portion 19a of the buffer holding table 10B for fixing the buffer holding table 10B to the floor. In addition, a part of the peripheral wall forming the buffer accommodating portion 19a is cut out to serve as a pin entrance 19c. When the buffer 10A is inserted into the buffer accommodating portion 19a of the buffer holding table 10B to align the pin inlets and outlets 19c and 11 with each other, the top surfaces of the buffer 10A and the buffer holding table 10B are formed on the same plane.

The bumper 10A has a heart shape in plan view, and includes a first path 1, a second path 2, a third path 3, and a fourth path 4 through which the tip pin 223 passes. The first path 1 is a path extending from the pin entrance and exit 11 to the entrance of the first capture position 12 and inclined upward so that the front end pin 223 passes. The first capture position 12 is located compared to the pin final The capture position 14 is the side opposite to the pin entrance. The pin entrance 11 is located at a position corresponding to the positive position of the end pin 223 in front of the door side member 20 of the bumper 10A, and the outer peripheral wall 15 is cut into a gap with a width larger than the width of the front pin 223, The portion where the thickness of the bottom plate portion is greatly reduced. Thereby, the front end pin 223 can be easily entered. The boundary 501 between the pin entrance 11 and the first path 1 has almost no step difference (Fig. 2 and Fig. 3).

In this example, the first path 1 is slightly curved (arc) clockwise in plan view. By setting the first path 1 to be inclined upward, the first capture position 12 can be shaped as a shallow and deep trap hole. The path width of the first path 1 is slightly larger than the diameter of the front end pin 223, and there are guide walls on both sides of the path, that is, two side walls 111, 112. In addition, the front end pin 223 can rotate freely around the main shaft 221. Thereby, the front end pin 223 passes through the first path 1 only by the operation of pushing in the door. The first capture position 12 is located slightly inward of the pin final capture position 14 (opposite to the pin entrance 11), and the return step (operation of sliding door) in the capture step can be performed.

The second path 2 is a path extending from the first capture position 12 to the pin final capture position 14 and passing through the front end pin 223. The pin final catching position 14 is a portion which is located at a substantially center in the front-rear direction and the left-right direction in plan view and accommodates the front-end pin 223. In addition, the front end pin 223 is stored in the pin final catching position 14 by being pulled toward the door closing direction. Therefore, a stop wall 16 is formed on the pin entrance and exit side of the pin final catching position 14. The blocking wall 16 has a shape of a half circumference around the pin entrance / exit side of the pin final catching position 14. With this, even if the door is pulled strongly, the front end pin 223 does not come off. The depth of the pin final capture position 14 is deeper than the depth of the first capture position 12. Therefore, the end pin 223 falls into the pin final catching position 14 before passing through the second path 2. The path width of the second path 2 is slightly larger than the diameter of the front end pin 223, and has guide walls, that is, two side walls 113, 114. Since the second path 2 is deeper than the first path 1, the side wall 113 uses the end face of the first path 1 as wall. The side wall 114 is the outer wall of the bumper 10A. In addition, the front end pin 223 can rotate freely around the main shaft 221. Thereby, by pulling the door in the door closing direction, the front end pin 223 is guided by the two side walls 113 and 114 and passes through the second path 2. In this example, the second path 2 is a very slight curved shape (arc) which is clockwise in plan view, and has a slight upward slope or almost no slope. The second path 2 is shorter than the first path 1. By this, the sliding door operation is shortened compared with the sliding door operation in the capturing step, so that the operator can realize the difference between the sliding door operation and the sliding door operation. In FIG. 4, the first path 1 and the second path 2 are located on the lower side with a line connecting the center of the pin entrance 11 and the center of the pin final capture position 14 as the boundary, and become the passage of the pin in the capture step of the door.

The third path 3 is a path extending from the final capture position 14 of the pin to the entrance of the second capture position 13 and inclined upward so that the front end pin 223 passes. The second capture position 13 is located on the side opposite to the pin entrance and exit from the pin final capture position 14. In this example, the third path 3 is an extremely minute curved shape (arc shape) clockwise in plan view. By setting the third path 3 to be slightly inclined upward, the second capture position 13 can be formed into a shallow trap hole shape. The slope of the upward slope of the third path 3 may be the same as the slope of the first path 1. The path width of the third path 3 is slightly larger than the diameter of the front end pin 223, and has a guide wall, that is, two side walls 115, 116. The side wall 115 is an outer wall of the bumper 10A, and the side wall 116 is a stop wall 116. Thereby, in the releasing step, only by the operation of pushing the door, the front end pin 223 is guided by the two side walls 115 and 116 and passes through the third path 3. The third path 3 is shorter than the fourth path 4. Therefore, compared with the sliding door operation in the capturing step, the sliding door operation can be shortened, so that the operator can realize the difference between the sliding door operation and the sliding door operation. In addition, the second capture position 13 is located slightly inward than the pin final capture position 14 (opposite to the pin entrance 11), and the return step (the operation of pulling toward the door) in the release step can be performed. The boundary 502 between the pin final capture position 14 and the third path 3, There is almost no step difference (Figure 2 and Figure 3).

The fourth path 4 is a path extending from the second capturing position 13 to the pin entrance 11 and passing the front end pin 223. In this example, the plan view is a very slight curved shape (arc) clockwise, with a slight upward slope or almost no slope. Thereby, the pin entrance 11 can be used as a trap hole with respect to the fourth path 4. The fourth path 4 is approximately the same length as the first path 1, the path width is slightly larger than the diameter of the front end pin 223, and it has two side walls 117, 118 which are guide walls. The side wall 117 is a stop wall 116, and the side wall 118 is an outer wall of the bumper 10A. Thereby, only by the operation of the sliding door, the front end pin 223 is guided by the two side walls 117 and 118 and passes through the fourth path 4. The pin entrance 11 sinks from the fourth path 4. That is, the extreme end of the fourth path 4 becomes the wall 44 of the pin entrance 11 (see FIG. 1). Therefore, the front end pin 223 does not enter the fourth path 4 during the door push-in step of the capturing step. The third path 3 and the fourth path 4 are located on the opposite sides of the first path 1 and the second path 2 with a line connecting the center of the pin entrance 11 and the center of the pin final catching position 14 (in FIG. 4, (Upper side), the passage of the pin in the door release step. That is, the first path 1 and the second path 2 and the third path 3 and the fourth path 4 are located on opposite sides of each other with a line connecting the center of the pin entrance 11 and the center of the pin final catching position 14 as a boundary.

The door stop 50 of the present invention includes a floor-side member 10 and a door-side member 20. The door-side member 20 will be described with reference to FIGS. 5 to 9. The door-side member 20 has a pin 22 whose front end pin 223 rotates in a horizontal direction, and a potential energy is added downward by an elastic force, and is raised by an external force. The pin 22 includes a main shaft 221 that extends in the vertical direction, a wrist portion 222 that is bent at the front end of the main shaft 221 to extend laterally, and a front end pin 223 that is bent from the front end of the wrist portion 222 and extends downward. In this way, by eccentrically positioning the main shaft 221 and the front end pin portion 223 in a plan view, the front end pin portion 223 can be horizontally centered on the main shaft 221. To turn. In addition, as long as the front end of the front end pin 223 does not contact the floor and contacts the bottom surface of the pin exit 11, if the door is opened, the front end of the front end pin 223 enters the pin exit 11. The pin 223 can move against the bottom surface of the first path 1 to the fourth path 4 while drawing the heart shape.

The door-side member 20 includes a pin 22, a spring member 24 that applies potential energy to the pin 22 downward, a fixed-side support portion 20A that supports the pin 22, and a housing 20B that covers a fixed-side support portion 20A other than the front end pin 223 . The fixed-side support portion 20A includes a cylindrical portion 211 that houses components related to the pin 22 therein, an upper flange 212 having an opening 215 in the center of the upper end of the blocking cylindrical portion 211, and a lower flange 213 that An opening is formed in the center of the lower end of the blocking cylindrical portion 211; and a back plate portion 214 is fixed to the facade. The opening 215 of the upper flange 212 taps a female thread for screwing the stop screw 23 on the upper end of the stop coil spring 24, and the opening 216 of the lower flange 213 serves as an opening through which the main shaft 221 of the pin 22 passes.

The fixed-side support portion 20A is a member fixed to the facade, and a mountain-shaped protrusion is formed on the inner peripheral surface below the cylindrical portion 211 and on the center of the floor-side member 10 side to be locked with the pin-side locking portion 261. (Convex shape) 219 (see FIG. 8). In addition, a plate-shaped stopper 217 (see FIG. 8) extending in the vertical direction is formed on the inner peripheral surface below the cylindrical portion 211 of the fixed-side support portion 20A and at the center on the opposite side of the floor-side member 10. The mountain-shaped protrusion 219 is engaged with the concave-shaped notch 216 corresponding to the mountain shape of the pin side. For example, at the end of the release step, after the front end pin 223 is released from the pin entrance 111, the pin 22 is slightly generated. The lateral vibration of the pin 22 is abutted by the side of the mountain that forms the protrusion and the side of the mountain that forms the notch, and the pin 22 is added with potential energy downward by the spring. Therefore, the lateral vibration of the pin 22 is corrected and the pin 22 returns. positive 面 位置。 Face position. When the pin 22 is rotated, the plate-shaped stopper 217 abuts against the side end surface 262 of the semi-cylindrical portion of the pin-side guide member 26 to restrict its rotation. In this example, the front end pin 223 is set to rotate about 180 ° around the main shaft 221, and does not rotate beyond this. That is, the reason for suppressing the rotation of the front end pin 223 to 180 ° on the floor side member 10 side is as follows. For example, at the beginning of the capturing step, the pin front end 223 has been rotated 90 ° from the center by an obstacle such as a child's foot before the pin front end 223 enters the pin entrance / exit 11 as long as it can abut the floor-side member 10 in this state. can. At this time, even if the front end pin 223 does not pass through the pin entrance 11 and enters the first path 1 or the third path 3, as long as the door is pushed or returned by using the subsequent operation, the front end pin 223 will remain as it is and enter the final position. Capture position 14 or return pin exit 11.

In the fixed-side support portion 20A, the pin 22 and the pin-side guide member 26 are rotatably supported by a spring in which a potential energy is added downward. The pin 22 and the pin-side guide member 26 are integrated by a bolt 25. The reason for integrating the pin 22 with the pin-side guide member 26 is because the minimum length of the pin 22 is larger than the diameter of the opening 215 of the upper flange 212 and the opening 216 of the lower flange 213, and Since the minimum length is larger than the diameter of the opening 216 of the lower flange 213, it cannot be installed in the fixed-side support portion 20A after integration. The pin-side guide member 26 has the structure shown in FIGS. 6 and 7, and a cutout is formed below the cylindrical member 26A and on the rear side, thereby lowering the cylindrical member 26A by about 180 ° in the circumferential direction. A part becomes a cylindrical body, and the end surface 262 of a circumferential direction is formed. When the pin 22 rotates around the main axis, the end surface 262 comes into contact with the stopper 217 of the fixed-side support portion 20A to prevent the pin 22 from vibrating excessively (rotating too much). A short cylindrical protrusion 26B is formed on the upper portion of the cylindrical member 26A, and the short cylindrical protrusion 26B is formed with a screw hole 263. The short cylindrical protrusion 26B supports one end of the coil spring 24. The symbol 27 is an O-ring.

A method of attaching the pin 22 and the like to the fixed-side support portion 20A will be described. The pin 22 is positioned below the fixed-side support portion 20A, and the main shaft 221 is inserted from the opening 216 of the lower flange 213. Then, the pin-side guide member 26 is positioned above the fixed-side support portion 20A, and falls through the opening 215 of the upper flange 212. The maximum outer diameter of the pin-side guide member 26 is smaller than the diameter of the opening 215 of the upper flange 212. The pin 22 and the pin-side guide member 26 are integrated by locking the positioning and locking portion 225 of the pin 22 and the positioning and locking portion 263 of the pin-side guide member 26. Next, the bolt 25 is inserted from the opening 215 of the upper flange 212 and screwed into the screw hole 263 of the pin-side guide member 26 and the screw hole 224 of the pin 22. Thereby, the pin 22 and the pin-side guide member 26 can be integrated in the fixed-side support portion 20A. The object integrating the pin 22 and the pin-side guide member 26 naturally falls within the fixed-side support portion 20A, and the lower end 264 of the pin-side guide member 26 abuts on the upper flange 213 of the lower portion of the fixed-side support portion 20A. It is placed on the lower flange 213. Then, as long as the pin-side locking portion 261 of the pin-side guide member 26 is locked to the mountain-shaped protrusion 219 of the fixed-side support portion 20A, the front end pin 223 comes to correspond to the pin entrance and exit 11 of the floor-side member 10. Position (ready position). Next, the coil spring 24 is inserted from the opening 215 of the upper flange 212 and is stopped by the stop bolt 23. Thereby, the object integrating the pin 22 and the pin-side guide member 26 is added with potential energy downward by the spring, and can be freely rotated to a predetermined angle as long as a lateral external force is applied to the front end pin 223. After the pins 22 and the like are mounted on the fixed-side support portion 20A, the housing 20B is mounted, and then, as long as the fixed-side support portion 20A is mounted on the facade, the installation of the door-side member 20 can be completed (FIG. 9).

Next, a method of using the door stop 50 will be described. The method of using the door stop 50 includes a capturing step of locking the pin 22 to the floor-side member 10, opening and holding the door, and releasing the locking of the pin 22 caught on the floor-side member 10 to close the door. Its release steps. Next, a capture step will be described with reference to FIGS. 10 to 13. In FIGS. 10 to 13, the same constituent elements as those in FIGS. 1 to 9 are assigned the same reference numerals and descriptions thereof are omitted, and mainly different points will be described. The capture step begins with the door opening operation (Figure 10). At this time, the front end pin 223 advances toward the pin entrance / exit 11. At this time, even if a slight external force is applied to the pin 22 to cause the front end pin 223 to vibrate slightly laterally, the mountain-shaped protrusion 219 of the fixed-side support portion 20A and the pin-side locking portion 261 of the pin-side guide member 26 are locked. Can still recover and maintain the original lock. Then, the front end pin 22 enters the pin entrance 11 (FIG. 11).

Next, the door 91 is further pushed toward the floor-side member 10 side. At this time, the front end pin 223 does not advance toward the fourth path 4 where the most terminal wall 44 exists, but advances toward the first path 1. In the first path 1, the guide walls 111 and 112 are on both sides of the path, and the front end pin 223 can rotate freely about the main shaft 221. Even if it is inclined upward, the pin 22 still rises by resisting the elastic potential of the spring 24 Wait, and smoothly advance on the first path 1 to reach the first capture position 12 (FIG. 12). At this time, the first capture position 12 becomes a trap hole with respect to the first path 1 and transmits a clicking sound or a tactile sensation to the operator by elastically adding potential energy. Then, pull in the direction of closing the door 91. There is almost no step from the first capture position 12 to the second path 2, and by pulling the door 91, the front end pin 22 enters the second path 2. In the second path 2, the guide walls 113 and 114 are formed on both sides of the path, and the front end pin 223 can rotate freely about the main shaft 221. Therefore, the second path 2 smoothly advances to the final capture position 14 (FIG. 13). At this time, the final capture position 14 becomes a trap hole with respect to the second path 2, and a click sound or a tactile sensation is transmitted to the operator by elastically added potential energy. Thus, the capturing step ends by performing both the operation of sliding the door and the operation of sliding the door.

Next, the release procedure will be described with reference to FIGS. 14 to 15. Hutu In FIGS. 14 to 15, the same constituent elements as those in FIGS. 10 to 13 are assigned the same reference numerals and descriptions thereof will be omitted, and differences will be mainly described. The releasing step starts from a state where the front end pin 223 is fitted in the final capture position 14. First push the door 91. At this time, there is almost no step difference across the third path 3 from the final capture position 14. In addition, since the extreme end of the second path 2 is a wall surface, the tip pin 223 does not enter the second path 2 and enters the third path 3. In the third path 3, guide walls 115 and 116 are formed on both sides of the path, and the front end pin 223 can rotate freely about the main shaft 221. Therefore, it smoothly advances on the third path 3 and reaches the second capture position 13 (FIG. 14). At this time, the second capture position 13 becomes a trap hole with respect to the third path 3, and the rattling sound or tactile sensation is transmitted to the operator by elastically adding potential energy. Next, the operation of pulling the door 91 is performed. Since the extreme end of the third path 3 is a wall surface, the front end pin 223 does not enter the third path 3 and advances toward the fourth path 4. In addition, there is almost no step from the second capture position 13 to the fourth path 4, and by pulling the door 91, the front end pin 22 enters the fourth path 4. In the fourth path 4, the two sides of the passage become guide walls 117 and 118, and the front end pin 223 can rotate freely about the main shaft 221. Therefore, the front end pin 223 smoothly advances on the fourth path 4 to reach the pin entrance 11 and finally from the pin entrance 11 flew out (Figure 15). In this way, the releasing step is ended by performing both the operation of sliding the door 91 and the operation of sliding the door, similarly to the capturing step.

Next, other methods of using the door stop 50 will be described. For example, when the front end pin 223 hits an obstacle before it enters the pin entrance 11, the pin-side guide member 26 abuts against the stopper 217 of the fixed-side support portion 20A, and the front end pin 223 is significantly (for example, deviated from the positive position by 90 ° ) In the case of eccentricity, you can keep the state and enter the capture step. That is, the front-end pin 223 is pushed in and hits the outer wall of the bumper holding table 10B of the floor-side member 10. At this time, since the stopper portion 217 of the fixed-side support portion 20A is provided, the pin 22 does not rotate beyond this position. Therefore, the front end pin 223 crosses the buffer The outer wall of the holding table 10B enters the first path 1 or the fourth path 4. Then, as long as the operation of sliding or sliding the door 91 is performed, the front end pin 223 can enter the pin exit 11 or the final capture position 14 to end the capture step or the release step. Furthermore, in this example, the buffer holding table 10B takes the operation of crossing the outer wall into consideration, and sets the inclination of the outer wall in the front part to be gentler than the inclination of the outer wall in the rear part.

The floor-side member and the door stop of the present invention are not limited to the above-mentioned embodiments, and various modifications can be adopted. In the door-side member 20, as described above, the pin 22 and the pin-side guide member 26 are formed by integrating different members with bolts, but they are not limited thereto, and may be integrated from the beginning. At this time, it is only necessary to increase the opening 215 of the upper flange 212 of the fixed-side support portion 20A so that it can be inserted into the fixed-side support portion 20A from above. In addition, in the door-side member 20, the pin-side locking portion 261 of the pin-side guide member 26 and the stop portion 217 of the fixed-side supporting portion 20A may be omitted. In this case, although the front end pin 223 is rotated 360 ° around the main shaft 221 or a slight lateral vibration of the front end pin 223 cannot be automatically restored, the position of the front end pin 223 may be manually corrected. Even in such a modification, the same effect as that of the embodiment can be obtained. In addition, below the cylindrical member 26A, a part of the cylindrical body is formed at about 180 ° in the circumferential direction, but it is not limited thereto, and may be a part of the cylindrical body that is less than 120 ° to 180 ° in the circumferential direction.
