Description

  The present invention relates to a door gap closing device for closing a gap between a lower end of a door and a floor surface when the door is closed.

  A door mounting frame is provided on a wall surface that separates a room from a room such as a house, and the door is attached to the mounting frame so that the door can be opened and closed. That is, one end of a hinge is connected to one side surface in the width direction of the door, and the other end of the hinge is connected to the mounting frame so that the door can be opened and closed on the mounting frame.

  If the door is provided on the attachment frame so that it can be opened and closed, it is inevitable that a gap is generated between the lower end of the door and the floor surface. For this reason, in the winter season, there are cases where a draft is introduced and warm air escapes to the outside. In summer, air that has been cooled may escape to the outside or warm air from outside may enter, leading to a reduction in air conditioning efficiency. In addition, indoor sound and light may leak to the outside through the gap between the door and the floor, which is also not preferable.

  Therefore, at the lower end of the door, when the door is closed, the clearance between the lower end of the door and the floor surface is closed, and when the door is opened, a closing member is provided at the lower end so as not to obstruct the opening and closing of the door. A door has been developed. Such prior art is disclosed in Patent Document 1.

  Patent Document 1 discloses three structures, one of which has a knob interlocking piece that interlocks with a door knob, and when the knob is operated when the door is opened, the knob interlocking piece rises, and a roller pressing piece. Moves in the horizontal direction by the restoring force of the spring. As a result, the closing member that closes the gap when the door is closed rises from the floor surface by the restoring force of the other spring.

  When the door is closed, the roller pressing piece moves in the horizontal direction against the restoring force of the spring by the knob interlocking piece, and the roller provided on the closing member is pressed to lower the closing member. Thereby, the gap between the lower end of the door and the floor is closed. The raising position and the lowering position of the closing member are determined by the height of the step formed on the roller pressing piece.

  In the second structure, a sliding bar is provided at the lower end portion of the door so as to be movable with one end portion protruding from one side surface serving as a rotation center of the door. When the door is closed, the sliding rod is pressed and moves against the restoring force of the spring.

  As a result, the connecting member having one end pivotally attached to the sliding rod rotates around the middle part, and the closing member pivotally supported by the other end of the connecting member descends so that the lower end of the door and the floor surface Close the gap. If the door is opened, the sliding rod moves due to the restoring force of the spring and the connector rotates in the opposite direction, so that the closing member does not rise and interfere with the door opening operation. It has become. The ascending position and the descending position of the closing member are determined by the amount of movement of the sliding rod and the rotation angle of the connector according to the amount of movement.

  In the third structure, a sliding piece that moves in accordance with opening and closing of the door is provided at the lower end of the door. One end of the sliding piece protrudes from the one end in the width direction with the spring serving as the center of rotation of the door. A pin is provided on the sliding piece, and this pin is engaged with an inclined groove formed in a support piece connected to the closing member.

  Accordingly, when the door is closed and the sliding piece moves in the width direction of the door against the restoring force of the spring, the pin moves from the lower end to the upper end of the inclined groove. The gap between the lower end and the floor is closed.

When the door is opened and the sliding member moves by the restoring force of the spring, the pin moves from the upper end to the lower end of the inclined groove, so that the closing member rises and does not interfere with the door opening operation. Yes. The rising position and the lowering position of the closing member are determined by the amount of movement of the sliding member and the inclination angle of the inclined groove.
Japanese Utility Model Publication No. 63-76194

  However, according to the three structures described in Patent Document 1, the height of the ascending position and the descending position of the closing member is set to be constant regardless of the structure. For example, in the first structure, the height is determined by the height of the step formed on the roller pressing piece that moves in the horizontal direction when the knob is operated.

In the second structure, the ascending position and the descending position of the closing member are determined by the amount of movement of the interlocking bar in the horizontal direction and the rotation angle of the coupler that rotates according to the amount of movement.
In the third structure, the amount of movement of the sliding piece in the horizontal direction and the inclination angle of the inclined groove formed on the support piece on which the pin provided on the sliding piece slides according to the amount of movement are determined. .

  Therefore, in any of the three structures shown in Patent Document 1, the amount of vertical movement of the closing member is set according to the gap between the lower end of the door and the floor surface. When the actual gap is larger than the set gap, the gap may not be closed even when the door is closed, or when the door is small, the closing member strongly hits the floor surface before fully closing the door, In this state, the closing member is in a state in which it cannot be raised, so that the door cannot be reliably closed.

  Therefore, if the gap between the lower end of the door and the floor is different, the closure member must be redesigned to move at a distance corresponding to the gap as the door opens and closes. Sometimes it is scarce and unusable.

  The present invention provides a door gap that can be reliably closed by a closing member in accordance with the opening and closing of the door, even if the gap between the lower end of the door and the floor surface is different or uneven. It is to provide an occluding device.

This invention is a door gap closing device that is pivotally connected to a mounting frame by a hinge on one side in the width direction of the door, and closes the gap between the lower end of the door and the floor surface when the door is closed,
A moving shaft provided movably along the width direction at the lower end of the door;
A spring that elastically biases the moving shaft in a direction protruding from one side surface in the width direction, one end of which is connected to the mounting frame by the hinge of the door;
An interlocking member provided on the moving shaft so as to be movable in the vertical direction;
When the door is closed and the moving shaft is attached to the lower end of the interlocking member and the one end is pressed against the inner surface of the mounting frame and moves in the axial direction against the biasing force of the spring, the moving member descends together with the interlocking member. And a closing member that closes the gap between the lower end of the door and the floor surface,
The moving shaft is provided with an engaging pin, and the interlocking member has an inclined surface with which the engaging pin abuts and an opening having a width dimension in which the engaging pin can move in a direction away from the inclined surface. Is formed,
The closing member can be lowered in a range in which the engaging pin moves from the lower end to the upper end of the inclined surface of the interlocking member, and the closing pin is in the lowered position where the engaging pin is in contact with the middle portion of the inclined surface. In a state where the member closes the gap between the lower end of the door and the floor surface, the moving shaft can move in the axial direction against the biasing force of the spring in a direction in which the engagement pin is separated from the inclined surface. The present invention provides a door gap closing device.

A storage groove is formed in the lower end portion of the door, and a case having an open lower surface is provided in the storage groove over the entire length in the width direction,
In the case, there is provided a bearing body that movably supports at least one end portion and the other end portion in the axial direction of the moving shaft, and the bearing body located at one end in the axial direction has one end portion of the moving shaft. It is preferable that an accommodating portion is formed for accommodating the spring that is biased in a direction protruding from one side surface in the width direction of the door.

  According to the present invention, even if the closing member hits the floor surface before the door is fully closed, the moving shaft can be moved in the axial direction by further closing the door, so the gap between the lower end of the door and the floor surface Even if they are different, the gap can be reliably closed by the closing member.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows an attachment structure of a door 1. The door 1 is attached to an attachment frame 4 fitted in an opening 3 formed on a wall surface 2 of a house by a pair of upper and lower hinges 5 at one end in the width direction. . The door 1 is provided with a knob 6 so that the door 1 can be opened and closed.

  As shown in FIGS. 2 to 4, the lower end of the door 1 is formed with a storage groove 7 that is open on the lower end surface and both side surfaces in the width direction over the entire length in the width direction. The storage groove 7 is provided with a door gap closing device 8.

  The door gap closing device 8 has a case 11. The case 11 is formed in a box shape with an open lower end surface, and flanges 13 are bent outward on both sides in the width direction of the lower end. The case 11 is mounted in the storage groove 7 of the door 1, and the flange 13 is fixed to the lower end surface of the door 1 with screws.

  As shown in FIG. 2, bearing bodies 14 formed in a rectangular plate shape with synthetic resin or the like are integrally fixed to the case 11 with screws or the like at both longitudinal end portions and midway portions of the case 11. . These bearing bodies 14 are formed with bearing holes 15 (only one bearing body 14 is shown in FIG. 4), and a moving shaft 16 is supported in these bearing holes 15 so as to be movable. That is, the moving shaft 16 can move along the width direction of the door 1.

  As shown in FIG. 4, among the three bearing bodies 14, a bearing body that is rotatably connected to the mounting frame 4 of the door 1 by a hinge 5 and that is positioned at one end in the width direction serving as the rotation center of the door 1. 14 is formed with an accommodating portion 17 communicating with the bearing hole 15. One end of the moving shaft 16 protrudes outside through a through hole 18 formed in one end surface in the longitudinal direction of the case 11 through the housing portion 17.

  Although the movable shaft 16 is supported by the three bearing bodies 14 so as to be movable, only a pair of bearing bodies 14 may be supported so as to be movable at both ends in the axial direction.

  A flange 19 is provided integrally with the moving shaft 16 at one end portion of the moving shaft 16 located in the accommodating portion 17. A spring 21 is mounted in a compressed state between the flange 19 and one end face of the accommodating portion 17. Accordingly, the moving shaft 16 is elastically biased in a direction in which one end portion in the axial direction protrudes from the through hole 18 of the case 11 to the outside by the restoring force of the spring 21.

  Interlocking members 22 formed in a rectangular plate shape with synthetic resin are accommodated in the case 11 at positions corresponding to both axial ends of the moving shaft 16 so as to be movable in the vertical direction. As shown in FIG. 3, the interlocking member 22 is formed with an insertion groove 23 into which the moving shaft 16 is inserted so as to open on the upper surface and both side surfaces.

  The pair of interlocking members 22 are provided so that one end surfaces thereof are close to one end surfaces of the pair of bearing bodies 14 that support both end portions of the moving shaft 16. This restricts the movement shaft 16 from moving in the axial direction.

  The interlocking member 22 is formed with openings 24 penetrating in the thickness direction on two side walls separated by the insertion groove 23. The opening 24 is formed in a quadrangular shape, in this embodiment, in a trapezoidal shape, and one of the four inner surfaces is formed in the inclined surface 24a. A pair of engaging pins 25 project from both ends of the moving shaft 16 inserted into the insertion grooves 23 of the pair of interlocking members 22 at positions shifted by 180 degrees in the circumferential direction. The pair of engagement pins 25 are located in the pair of left and right openings 24 of the interlocking member 22.

  As shown in FIG. 2, the pair of interlocking members 22 are mounted on the moving shaft 16 with their inclined surfaces 24a facing in the same direction. As shown in FIGS. 3 and 4, both ends in the longitudinal direction of the strip-shaped mounting bracket 26 are screwed and fixed to the lower ends of the pair of interlocking members 22, and rubber is mounted on the lower end of the mounting bracket 26. A closing member 27 formed in a band shape by an elastic material such as is attached.

  When the moving shaft 16 is urged in a direction protruding from a through hole 18 formed in one end surface of the case 11 by the restoring force of the spring 21, the engaging pin 25 is as shown in FIG. As shown in FIG. 6 (a), it is in contact with the lower end of the inclined surface 24 a of the opening 24.

  A direction in which the door 1 is closed and one end of the moving shaft 16 protruding from the through hole 18 is pressed by the inner surface of the mounting frame 4 and is pushed into the case 11 against the biasing force of the spring 21. The contact position of the engagement pin 25 with respect to the inclined surface 24a moves upward from the lower end of the inclined surface 24a. Accordingly, the interlocking member 22 is displaced together with the closing member 27 in a direction protruding from the lower end surface of the door 1, that is, downward.

  Next, the operation of the door gap closing device 8 configured as described above will be described with reference to FIGS. 5 (a) to 5 (c) and FIGS. 6 (a) to 6 (c). In this embodiment, the vertical movement distance of the closing member 27, that is, the vertical movement distance when the engagement pin 25 moves from the lower end to the upper end of the inclined surface 24a as shown in FIG. And Further, the vertical movement distance of the closing member 27 when the one end portion of the moving shaft 11 is pressed by the inner surface of the mounting frame 4 until the door 1 is fully closed is set to be the same as the dimension Y. Yes.

  First, the case of FIGS. 5A to 5C will be described. In this case, when the door 1 is opened as shown in FIG. 5A, the gap between the lower end of the closing member 27 (the lower end surface of the door 1) and the floor surface F has a dimension X smaller than Y. In the state where the door 1 is opened, the engagement pin 25 is located at the lower end of the inclined surface 24a.

  When the door 1 is rotated in the closing direction from the state of FIG. 5A, the end of the moving shaft 16 is pressed by the inner surface of the mounting frame 4. Thereby, the moving shaft 16 moves in the direction of entering the case 11 against the urging force of the spring 21.

  As shown in FIG. 5 (b), when the engagement pin 25 moves from the lower end of the inclined surface 24a to the middle before the door 1 is fully closed, the closing member 27 descending together with the interlocking member 22 is the floor surface. The gap between the lower end surface of the door 1 and the floor surface F is closed by hitting F.

  When the door 1 is further closed from the state of FIG. 5B until it is fully closed, the moving shaft 16 is further pressed by the inner surface of the mounting frame 4. At that time, the moving shaft 16 moves in the axial direction, and the engagement pin 25 moves in the opening 24 in the direction away from the inclined surface 24a by the movement. Even if the engaging pin 25 is separated from the inclined surface 24a, the closing member 27 has already been in contact with the floor surface F, so that it is not displaced further downward.

  That is, even if the closing member 27 is not displaced downward, the engaging pin 25 provided on the moving shaft 16 can move within the opening 24 according to the width dimension of the opening 24. Therefore, even if the closing member 27 hits the floor F before the door 1 is fully closed, if the door 1 is further closed and the moving shaft 16 is pressed against the inner surface of the mounting frame 4, the moving shaft 16 moves. Therefore, the door 1 can be reliably closed until it is fully closed.

  That is, since the gap between the closing member 27 and the floor surface F is a dimension X that is smaller than the dimension Y by which the closing member 27 can be displaced in the vertical direction, the closing member 27 is moved to the floor surface F before the door 1 is fully closed. Even if it hits, the door 1 can be fully closed reliably.

  6A to 6C show a dimension Y in which a gap between the closing member 27 (the lower end surface of the door 1) and the floor surface F can be displaced in the vertical direction of the closing member 27, that is, a height dimension of the inclined surface 24a. 6 (a) shows a state in which the door 1 is opened. At this time, the gap between the closing member 27 and the floor surface F is Y.

  When the door 1 is rotated in the closing direction from the state shown in FIG. 6A, the end of the moving shaft 16 hits the inner surface of the mounting frame 4 and is pressed, so that the moving shaft 16 resists the biasing force of the spring 21. Then move.

  FIG. 6B shows a state before the door 1 is fully closed. In this state, the engagement pin 25 provided on the moving shaft 16 abuts on the middle portion of the inclined surface 24a of the opening 24 in the height direction. ing. Therefore, since the descending dimension of the interlocking member 22 is smaller than the dimension Y of the gap between the closing member 27 and the floor surface F, in this state, the gap between the closing member 27 and the floor surface F is not closed yet.

  When the door 1 is closed until it is fully closed as shown in FIG. 6C, the moving shaft 16 is further pressed and moved by the inner surface of the mounting frame 4, so that the engaging pin 25 is in the middle of the inclined surface 24a. Move from to the top.

  As a result, the interlocking member 22 is displaced downward in a dimension corresponding to the height dimension (vertical dimension) of the inclined surface 24a. Since the vertical dimension of the inclined surface 24a is substantially the same as the dimension Y of the gap between the closing member 27 and the floor F before the door 1 is closed, the closing member 27 is closed by fully closing the door 1. Thus, the gap generated on the lower end surface side of the door 1 can be reliably closed.

  Thus, according to the door gap adjusting device 8 of the above-described embodiment, the size of the gap on the lower surface side of the door 1 that can be closed by the closing member 27 is such that the closing member 27 extends from the raised position to the lowered position. The gap is not limited to the gap corresponding to the displacement dimension Y that can be displaced, and even a gap with a smaller dimension can be reliably closed.

  That is, the engagement pin 25 is brought into contact with the inclined surface 24 a of the trapezoidal opening 24 formed in the interlocking member 22 that is interlocked with the vertical movement of the closing member 27. Therefore, even if the closing member 27 hits the floor surface F in a state where the engagement pin 25 is engaged with the middle portion in the height direction of the inclined surface 24a before the door 1 is fully closed, the door 1 is further increased. If the moving shaft 16 is pressed by rotating the door in the closing direction, the engagement pin 25 moves in the direction away from the inclined surface 24a in the opening 24, and therefore the moving shaft until the door 1 is fully closed. 16 can be moved.

  Therefore, even when the gap between the lower end of the door 1 and the floor surface F is smaller than the maximum descending dimension Y of the closing member 27, the door 1 is fully closed and the closing member 27 is reliably closed. Can do.

  The door gap closing device 8 configured as described above is unitized by housing the interlocking member 22 to which the bearing body 14, the spring 21, the moving shaft 16 and the closing member 27 are attached in the case 11. Therefore, it is possible to incorporate the case 11 into the door 1 simply by mounting the case 11 in the storage groove 7 formed at the lower end of the door 1. That is, since the door gap closing device 8 is unitized, the assembling work for the door 1 can be performed easily and quickly.

  In the above embodiment, the shape of the opening formed in the interlocking member is a trapezoidal shape, but it may be a shape having an inclined surface, for example, a triangular shape, and the engagement pin is in the middle of the inclined surface. Then, when the door is not fully closed and the closing member hits the floor surface, when the door is further rotated in the closing direction, the engagement pin can move in a direction away from the inclined surface together with the moving shaft. That's fine.
