Description

  The present invention relates to a door stop in which a floor member is provided with both a catch function for keeping the door open and a stopper function for preventing the door from colliding with a wall surface.

  Conventionally, when a door installed in each room of a house is opened, a flooring door stop is known as a means for preventing a collision with a wall surface and maintaining the opened state. In general, the floor surface in front of the wall to avoid a crash is provided with a cushioning material on the surface facing the door and a ring-like engagement member, and is attached to the front end of the door. What consists of a hook-shaped engaging member on which this engaging tool is hung is used.

  In recent years, various improved forms of door stop have been proposed. Japanese Patent Application Laid-Open No. 2000-45606 of Patent Document 1 includes a door stop main body fixed to a floor, an upper end portion of the door stop main body fixed to the door, and a locking body formed to be able to be held. A door stop in which holding force adjusting means is disposed on either the hit body or the locking body is disclosed. Further, in Japanese Patent Application Laid-Open No. 2000-248808 of Patent Document 2, a magnet that magnetically attaches a magnetically attached portion provided on a door or a temporary door made of a magnetic material is engaged with a door stopper made of an elastic material. A door stop device formed side by side is disclosed. Japanese Patent Application Laid-Open No. 10-252336 of Patent Document 3 discloses a stopper rod as a mounting piece, and a protruding piece formed at the tip of the stopper rod is movable in a horizontal direction and a vertical direction, and is unidirectional by a spring. Stopper fixed with a groove that consists of a stopper movable body arranged so as to be biased and a forward path, a locking part, and a return path with a height difference that guides the protruding piece formed at the tip of the stopper rod of the stopper movable body The door stop which consists of a body is disclosed.

Japanese Patent Application Laid-Open No. 11-81790 of Patent Document 4 discloses an arm that is fixed to the upper frame and extends to the door opening side, a stopper portion attached to the tip of the arm, and a stopper portion that is fixed to the top of the door. In a door stop structure comprising a catch member that holds a stopper portion and is released by a closing operation force of the door, a pair of catch pieces are provided facing the receiving member. A door stop structure in which the catch pieces of the pair appear and disappear independently is disclosed.
JP 2000-45606 A (Claims, FIGS. 1 and 2) JP 2000-248808 A (Claims, FIG. 1) JP 10-252336 A (Claim 1) JP-A-11-81790 (Claim 1)

  However, the door stop described in each of the above publications has a problem that the engagement between the door stop main body and the locking body is not always sufficient. In addition, when a stopper function that prevents a collision with the wall surface is required when the door is opened, a locking member unnecessary for the stopper function is exposed, which is difficult to use. Moreover, it was a structure which is easy to be damaged when a door hits a wall surface violently. Therefore, both the catch function for keeping the door open and the stopper function for preventing the door from colliding with the wall surface are given to the floor side member, and when used as a stopper, the extra member is not exposed. The door-to-door appearance that can be made into a simple shape was desired.

  Accordingly, the object of the present invention is to provide both a catch function for maintaining the door in an open state and a stopper function for preventing the door from colliding with the wall surface to the floor member, and when used as a stopper, An object of the present invention is to provide a door stop that can be formed into a simple shape in which no extra members are exposed.

  That is, according to the present invention, a door-side bar-like member that is horizontally spaced from the side face of the door and is fixed in a posture in which the shaft core extends in the vertical direction, and a side face where the door-side bar-like member enters and exits are opened. A substantially cylindrical floor-side fixing member having a door-side bar member accommodating portion, and the floor-side fixing member is rotatable between a position where the opening is “open” and a position where the opening is “closed” And a floor-side member having a cover member fitted so as to provide a door stop.

  According to the present invention, if the door is opened, the door-side bar-like member is accommodated in the door-side bar-member housing portion of the floor-side member, and the cover member is manually turned to the position where the opening is closed, the door-side bar-like member can be contained. Therefore, the door can be stably maintained in the opened state. Moreover, since the door stop of this invention is flooring, anyone can operate a cover member. On the other hand, in the conventional door stop structure disclosed in Japanese Patent Laid-Open No. 11-81790, the door stop structure is fixed to the upper frame, so that it is difficult for a short person to operate. Moreover, if the cover member of the floor side member is set in a position where the opening is closed in advance, it can be used as a stopper to prevent the door from colliding with the wall surface of the door, and the shape of the floor side member is excessive. It becomes a simple columnar shape that does not expose the member and is easy to use.

  Next, the door stop in the embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a door of this example, FIG. 2 is an exploded perspective view of a floor member, FIG. 3 is an exploded perspective view of the floor member of FIG. 1 viewed from the opposite side, and FIG. 5 is a perspective view of the door stop of FIG. 1 as viewed from above, and FIG. 6 is the door stop of FIG. 1, where the door side bar-like member is the door side bar-like member of the floor side member. FIG. 7 is a view of the door of FIG. 6 as viewed from above, FIG. 8 is a view of the state where the cover member is turned from the state of FIG. 6 and the opening is closed, and FIG. 9 is the view of FIG. FIG. 10 is an exploded perspective view of the floor-side fixing member, FIG. 11 is an exploded perspective view of the floor-side fixing member of FIG. 10 viewed from the back side, and FIG. 12 is a floor-side fixing member of this example. FIG. Note that the door-side bar-shaped member in FIGS. 7 and 9 is indicated by a solid line.

  The door stop 10 includes a door side member 1 fixed to the door surface and a floor side member 2 installed on the floor surface. The door-side bar-shaped member 11 is fixed to the side surface of the door A in a posture that is spaced apart from the side surface in the horizontal direction and the shaft core extends in the vertical direction. In this example, a cylindrical door-side bar-shaped member 11 is provided with a substantially trapezoidal cross-section columnar body (attachment member) 12 having a predetermined height (horizontal length) and a predetermined length (vertical length). It is installed on the surface. Further, the lower end portion of the columnar door-side bar-shaped member 11 protrudes downward from the lower end of the columnar body 12. The protruding portion is a portion that fits into the door-side bar-shaped member accommodating portion, and the length thereof is appropriately determined so that the rotation of the cover member does not become an obstacle when the opening is closed. Reference numeral 13 denotes a screw hole.

  As shown in FIGS. 2 and 3, the floor-side member 2 includes a floor-side fixing member 21 that is fixed to the floor surface, and a cover member 22 that is rotatably fitted to the floor-side fixing member 21. The floor-side fixing member 21 has a substantially cylindrical shape having a door-side bar member accommodating portion 26 whose side surface where the door-side bar-shaped member 11 enters and exits opens. 2 and 3, reference numeral 23 denotes an opening. In addition, the substantially cylindrical “substantially” includes, as will be described later, a form having a disk-like bottom part (a collar part) and a form different from the literal cylindrical form because it has an opening. Because.

  In this example, the floor-side fixing member 21 has a disk-shaped bottom portion 211 having an outer diameter larger than the outer diameter of the floor-side fixing member main body 212 whose back surface is in contact with the floor surface. Thereby, it becomes easy to screw on the floor surface, and when the cover member 22 is fitted, the appearance becomes a simple columnar shape.

  The opening dimension (opening width) in the left-right direction of the opening 23 of the floor-side fixing member main body 212 is about 1.5 to 2 times the diameter of the door-side bar-shaped member 11 and is gradually reduced toward the center. . As a result, the door-side bar-shaped member 11 can easily enter, and the fixing stability of the door-side bar-shaped member 11 is increased in the fixed state. The door-side bar member accommodating portion 26 is a space portion having a diameter that is slightly larger than that of the door-side bar member 11 in which the opening side of the floor-side fixing member 21 and the ceiling are both open.

  A fitting groove 214 into which the arc-shaped protrusion 223 of the cover member 22 is fitted is formed on the peripheral surface 213 of the lower portion of the floor side fixing member main body 212. The fitting groove 214 includes two arc-shaped grooves sandwiching two peripheral surfaces 213 and 213 where no fitting groove is formed. Therefore, the length of the arc of one arc-shaped groove of the two arc-shaped grooves is slightly shorter than the semicircular arc. Thereby, the arc length of the arc-shaped protrusion 223 formed on the cover member 22 can be made relatively long, and smooth rotation within a predetermined rotation range can be realized. The circumferential movement distance (rotation range) of the cover member 22 is a length obtained by subtracting the arc length of the arc-shaped protrusion 223 of the cover member 22 from the arc length of one arc-shaped groove. This length (rotation range) is slightly larger than the maximum width of the opening of the floor member 2. The peripheral surface 213 where the fitting groove 214 is formed is at a position below the opening 23.

  In this example, the floor-side fixing member 21 has a two-layer wall structure, and the wall portion forming the door-side bar member accommodating portion 26 is an insertion member 241 fitted therein. By fitting the insertion member 241, it is possible to provide strength to withstand even if the door-side bar member 11 collides, and to reduce the impact of the collision.

  In other words, the insertion member 241 has a substantially horseshoe shape in plan view having a predetermined height, and the door stake member 11 can easily enter by widening the opening of the opening 244. It is preferable that the insertion member 241 is made of a resin because it can prevent a metallic noise caused by a collision with the metal door-side bar member 11 and can reduce the impact. Further, a metal piece 242 having a substantially horseshoe shape in plan view with a height smaller than the height of the insertion member 241 is attached to the back surface of the insertion member 241 (FIGS. 10 and 11). Thereby, the intensity | strength of the insertion member 241 increases and it can endure the collision of the door side bar member 11. FIG.

  The insertion member 241 has engagement pieces 245 on the upper and lower sides of the rear side, so that the insertion member 241 can be easily fitted into the notch 216 of the outer layer member of the floor side fixing member 21. The insertion member 241 is fitted inside the outer layer member 212a of the floor-side fixing member 21 without a gap, and is flush with the upper end surface of the outer layer member 212a of the floor-side fixing member 21. Moreover, the wall on the opposite side to the opening into which the door side bar member 11 enters, that is, the wall excluding the opening is a vertical wall, and the catch stability of the door side bar member 11 is excellent. Further, the vertical wall has a double structure of a resin surface layer and a metal inner layer, and has excellent shape retention and strength. In addition, the top surface of the insertion member 243 has a semicircular arc-shaped protrusion 241, and the contact between the semicircular arc-shaped protrusion 241 and the back surface of the cover member 22 is set as a partial contact, thereby Smooth rotation is possible.

  On the outer peripheral surface of the floor-side fixing member 21, there is formed a recess 215 that avoids the arc-shaped protrusion 223 formed on the cover member 22 when the cover member 22 is fitted (FIGS. 2 and 11). Accordingly, the circumferential length (arc-shaped width) of the recess 215 is slightly larger than the arc-shaped length of the arc-shaped protrusion 223. Thereby, the arc-shaped protrusion 223 can be fitted into the recess 215. In addition, in the outer peripheral surface of the floor-side fixing member 21, another recess 215 is not formed at a position facing the recess 215 with the axial center as the center, but this position covers a portion corresponding to the opening. In addition, since the projection height of the arc-shaped projection 223 is small, the fitting is not hindered.

  On the bottom surface of the floor-side fixing member 21, two through holes through which the screws pass and recesses 35 into which the screw heads fit are formed. Thereby, the floor-side fixing member 21 can be fixed to the floor surface with screws, and the screw head does not protrude into the door-side bar member accommodating portion 26. Further, the bottom surface of the floor-side fixing member 21 is a two-step recess, and a plate-like screw head concealing member 217 is fitted (FIGS. 10 and 11). When the screw head concealing member 217 is fitted into the recess on the bottom surface, the bottom surface becomes flush. A through hole 219 is formed slightly on the opening side of the screw head concealing member 217. Thereby, for example, when disassembling the door stop 10, the screw head concealing member 217 can be easily removed by inserting the tip of the driver or the tip of the pencil into the through hole 219 and raising the tip. Further, the chamfered portion 218 is formed on the opening side of the screw head concealing member 217 so that the door side bar member 11 can be smoothly inserted.

  The cover member 22 is fitted to the floor side fixing member 21 so as to be rotatable between a position where the opening 23 is “open” and a position where the opening 23 is “closed”. In this example, the cover member 22 has a shape in which a part of the top plate portion and the side plate portion of the cylindrical cap-shaped object is cut out to form an opening 221. The shape of the opening 221 is substantially a fan shape in a plan view, and is a quadrangle shape in a front view. On the entrance / exit side of the door-side bar member 11 of the opening 221, a sill portion 222 is formed, and the cylindrical shape of the cover member 22 is maintained. Further, the edge member around the ceiling opening 221 is bent inward to form a rib structure. In addition, two arc-shaped protrusions 223 are formed on the inner peripheral surface of the lower end portion of the cover member 22 so as to have an axial core.

  The cover member 22 can have a double structure in which an inner cover member and an outer cover member are fitted. In this dual structure, if the outer cover member is a softer member than the inner cover member, when the door stop is used as a stopper, it becomes a cushioning material against the collision of the door side bar member 11, and the door side bar member 11 is It will not hurt. A protrusion 40 is formed on the outer peripheral surface of the cover member 22. Thereby, since a finger | toe hooks on the processus | protrusion 40, the cover member 22 can be rotated easily.

  Next, an example of an assembling method per door will be described. As shown in FIGS. 11 to 12, the bottom plate 211 of the outer layer member 212a of the floor side fixing member 21 is fixed to the floor surface with screws. The screwing uses two screw holes formed in the bottom plate 211 of the outer layer member 212 of the floor side fixing member 21. Next, the screw head concealing member 217 is inserted into the bottom surface of the outer layer member 212 of the floor side fixing member 21 and is fitted. Thereby, the screw head is hidden and the bottom surface becomes a flat surface. Next, the insertion member 241 is inserted into the inner surface of the outer layer member 212 and fitted. A horseshoe-shaped metal piece 242 is mounted on the back surface of the insertion member 241 in advance. Next, the cover member 22 is attached. When the cover member 22 is mounted, one of the arc-shaped protrusions 223 of the cover member 22 is matched with the recess 215 on the outer peripheral surface of the outer layer member 212 of the floor side fixing member 21, and the outer layer member 212 of the floor side fixing member 21 is fitted. The vertical position is determined so that the opening of the cover and the opening of the cover member 22 coincide (FIG. 3). If both the vertical positions match, the cover member 22 is moved downward from that position until the arc-shaped protrusion 223 of the cover member 22 is fitted in the fitting groove 214 of the floor-side fixing member 21. Push in. This gives 10 per door.

  Next, the usage method of the door stop 10 is demonstrated. The door stop 10 has both a catch function that keeps the door open and a stopper function that prevents the door from colliding with the wall surface. First, the function of keeping the door 10 per door open will be described with reference to FIGS. 4, 6 and 8. The floor side member 2 is set so that the opening of the floor side fixing member 21 and the opening of the cover member 22 are matched (FIG. 4). In this state, the door A is opened. When the door A is further opened, the distal end portion of the door-side bar member 11 enters the opening 23 of the floor-side member 2 and further enters the door-side bar member accommodating portion 26 of the floor-side member 2. At this time, even when the door A is opened violently and the door-side bar member 11 collides with the vertical wall of the insertion member 241 of the floor-side fixing member 21, the vertical axis has a two-layer structure and is reinforced with an inner metal piece. Since it is covered with the resin of the outer layer, the door-side bar member 11 can be caught stably without making a metal sound (FIG. 6).

  Next, the projection 40 of the cover member 22 is rotated in the direction of the arrow with a finger until the rotation stops, and the opening is closed (FIG. 8). Thereby, the door side bar member 11 can be confined in the floor side member 2. In this state, the door A never closes no matter what force is applied to the door A. Thus, the door stop 10 can stably maintain the door in the open state. Further, when closing the door A, the projection 40 of the cover member 22 is rotated with the finger in the direction opposite to the arrow direction until the rotation stops (FIG. 6). Then, the door A may be closed.

  Next, the stopper function of the door 10 will be described with reference to FIGS. FIG. 13 is a diagram for explaining the stopper function of the door of the door of this example, and FIG. 14 is a plan view of the door of FIG. In order to use the door stop 10 as a door stopper, first, the cover member 22 of the floor member 2 is turned so that the opening is closed in advance. Next, when the door A is opened, the door A does not collide with the wall surface because it collides with the side surface of the cover member 22 of the door stop 10. At this time, if the cover member 22 has a double structure and the outer layer is a softer member than the inner layer, the collision between the door-side bar member 11 and the floor-side member 2 can be mitigated. Thus, the door stop 10 has not only a catch function but also a stopper function.

  The door stop 10 of the present invention is not limited to the above embodiment, and various modifications can be adopted. In other words, the shape of the door-side bar member 11 is not limited to the cylindrical member, and may be a columnar body having a square cross-sectional shape, for example. Further, the floor-side fixing member 21 may be one in which the disk-shaped bottom portion 211 whose back surface is in contact with the floor surface is omitted. In addition, the vertical wall forming the door-side bar member housing portion of the floor-side fixing member 21 may be of a form that has an integrated structure in which the insertion member is fitted in advance, without using the method using the insertion member. Good.

  The door stop of the present invention can be installed in each room such as a house. In particular, this door stop has both a catch function that keeps the door open and a stopper function that prevents the door from colliding with the wall surface, so it can be used for changing the purpose of the room, the user of the room, or the original purpose. It is convenient because you can select which function to use.
