Summary of the Invention

Problems to be Solved by the Invention

[0004] The door stopper device described in Patent Document 1 locks the door's movement in the opening and closing direction through the cooperation of a door-side member fixed to the door and a floor-side member fixed to the floor, by mutual attraction or engagement. In order to perform this function, the door-side member and the floor-side member must be fixed to the door and the floor, respectively, so that they face each other or abut each other when the door reaches a predetermined position for fixing the door (hereinafter referred to as the locked position). However, when the door is in the locked position, it can be difficult to grasp the relative positional relationship between the door-side member and the floor-side member.

[0005] For example, consider a situation where the floor-side component is located close to a wall. In such cases, opening the door to the locked position to bring the door-side component and the floor-side component closer together results in the floor-side component being fixed to the back of the door (the side facing the wall), which is a narrow and hard-to-see location. In this case, the worker had to reach behind the door and mark the fixing position of the floor-side component with a pencil or scribing needle. Working in such a location was extremely cumbersome, and there was a risk of the marking position being inaccurate.

[0006] To solve this problem, a door stopper positioning jig is proposed in Patent Document 2. This door stopper positioning jig comprises a flat plate portion that follows the direction of the floor surface and a marking portion provided on the flat plate portion for marking the fixing position of the floor-side member. By using this door stopper positioning jig, the floor-side member can be positioned. Specifically, first, the door to which the door stopper positioning jig is attached is opened to the locked position, and the flat plate portion is attached to the floor at that position. Next, the door is closed to secure the working space. In this state, the floor-side member can be positioned by marking the floor according to the marking portion of the door stopper positioning jig. This makes it easier to work and prevents the marking position from shifting, even when the floor-side member is installed close to a wall.

[0007] However, even if the floor-side component is successfully attached to the floor, problems can arise such as the top of the floor-side component hitting the door if the gap is too narrow, preventing it from fitting into the gap, or conversely, the door-side component and the floor-side component being too far apart and not engaging with each other if the gap is too wide.

[0008] The objective of this invention is to facilitate the positioning of a door stopper device and to determine in advance whether the door stopper device can be installed. [Means for solving the problem]

[0009] To solve the above problems, this invention provides a door stopper installation unit and a door stopper positioning jig having the following configuration. [Configuration 1] A door stopper installation unit comprising a door stopper device consisting of a door stopper portion attached to the floor or ceiling and a door-side member attached to the door of a hinged door to lock the door stopper portion, and a door stopper positioning jig for determining the fixing position of the door stopper portion to the floor or ceiling, The door stopper positioning jig comprises a flat plate portion that is aligned with the surface direction of the floor or ceiling, a marking portion provided on the flat plate portion for marking the fixing position of the door stop portion, a raised portion that rises upward from the flat plate portion, and a mounting hole provided on the raised portion that extends in the vertical direction. The aforementioned rising portion is locked to the door-side member by fitting a projection extending laterally from the door-side member into the mounting hole, and the door stopper installation unit is such that the distance from the door stopper positioning jig to the floor or ceiling is variable by sliding vertically relative to the projection through the mounting hole.

[0010] [Configuration 2] The door stopper installation unit according to Configuration 1, wherein the flat plate portion protrudes toward the opening side of the door while the door stopper positioning jig is locked to the door side member, and the marking portion is provided on the protruding portion.

[0011] [Configuration 3] The door stopper installation unit according to configuration 1 or 2, wherein the door-side member is attached to the bottom surface of the door, and the projection is provided on both end faces of the door-side member in the door width direction.

[0012] [Structure 4] The door stopper installation unit according to any one of configurations 1 to 3, wherein the door stopper portion is provided with an engaging piece that is movable up and down relative to the floor or ceiling, and the door side member is provided with a locking member that is movable up and down relative to the door, an operating member that is movable laterally relative to the door, an elastic member that biases the operating member laterally, and an operating direction conversion mechanism that converts the lateral movement of the operating member into the up and down movement of the locking member.

[0013] [Composition 5] A door stopper positioning jig used in a door stopper installation unit described in any one of configurations 1 to 4, The system comprises a flat plate portion that is aligned with the surface direction of the floor or ceiling, a marking portion provided on the flat plate portion for marking the fixing position of the door stop portion, a raised portion that rises upward from the flat plate portion, and a mounting hole provided on the raised portion that extends in the vertical direction. A door stopper positioning jig is secured to the door side member by fitting a projection extending laterally from the door side member into the mounting hole, and the distance to the floor or ceiling is variable by sliding vertically relative to the projection through the mounting hole. [Effects of the Invention]

[0014] According to this door stopper installation unit, when the rising part of the door stopper positioning jig cannot be inserted into the gap, it can be determined that the gap between the floor or ceiling and the door is narrow and the contact part (floor side member) cannot enter the gap. Also, when the door stopper positioning jig is slid in the vertical direction while locked to the door side member and does not contact the floor or ceiling, it can be determined that the gap between the floor or ceiling and the door is wide and the distance between the contact part and the door side member is too large to engage with each other. By these means, it can be determined that before installing the contact part, the door side member and the contact part can be installed so as to be able to engage with respect to the gap between the floor or ceiling and the door. Therefore, it is possible to eliminate the trouble of having to remove the contact part that has been attached with great effort but does not function as a door stopper device. Also, by using the door stopper positioning jig, the positioning of the door stopper device can be easily performed.

[0016] Embodiments of this invention will be described based on the drawings. This embodiment is a door stopper installation unit that includes a door stopper device S and a door stopper positioning jig 60 as a set. Figure 1 shows a door stopper device S according to an embodiment of this invention. It shows the state of use of the door stopper device S used on a door D of a so-called hinged door 1, where the door D is fixed to a wall W or pillar with a hinge 3. By pulling or pushing the door knob 2 attached to the door D, the door D rotates around the pivot axis of the hinge 3, allowing the passage to be opened and closed.

[0017] As shown in Figure 2, the door stopper device S of this embodiment comprises a door stopper portion 10 (hereinafter referred to as the floor-side member 10 in this embodiment) provided on the floor F side and a door-side member 20 provided on the door D side. The floor-side member 10 is fixed to the floor F at a predetermined position (lock position) where the door D is fixed by screws, adhesive tape, etc. The door-side member 20 is fixed near the lower end of the door D by screws, adhesive tape, etc. Reference numeral 27 in Figure 2 indicates a hole through which a screw is screwed into the bottom surface of the door D. In this embodiment, since the door-side member 20 is thin, the door-side member 20 is fixed to the bottom surface of the door D.

[0018] The floor-side member 10 consists of a base portion 11 attached to the floor F, and a stopper portion 12 that is rotatably mounted on the base portion 11 via a horizontal pin (not shown), i.e., it is rotatably mounted relative to the floor F. In this embodiment, the stopper portion 12 is made of a plate-shaped member made of a magnetic material such as iron. The plate-shaped member is rectangular, and the pin is provided along one edge of the rectangle (the left edge in Figure 2). A locking hole 13 is provided near the pivoting end, which is the opposite side from where the pin is provided.

[0019] The door-side member 20 comprises a casing 21 fixed to the door D, a locking member 30 that is movable vertically relative to the casing 21, i.e., the door D, and an operating member 40 that is movable horizontally relative to the casing 21, i.e., the door D. The door-side member 20 also includes an elastic member 51 that biases the operating member 40 horizontally, and an operating direction conversion mechanism 50 that converts the horizontal movement of the operating member 40 into vertical movement of the locking member 30. A magnet 22 is also provided on the door-side member 20.

[0020] In this embodiment, the operating member 40 moves in a direction parallel to the width direction of the door D (the direction perpendicular to the thickness direction of the door D), but it is also possible to move it at a slight angle to the width direction of the door D. However, it is desirable that the direction of movement be horizontal. Hereinafter, the width direction of the door D will be simply referred to as the width direction, and the thickness direction of the door D will be simply referred to as the thickness direction.

[0021] As shown in Figure 5C, the locking member 30 is a integrally molded resin product. It consists of an L-shaped member 31 comprising a base portion 33 that rises vertically on one side in the thickness direction (left side in Figure 5C) and an overhang portion 37 that protrudes from the lower part of the base portion 33 to the other side in the thickness direction (right side in Figure 5C).

[0022] The protruding portion 37 has a claw portion 32 that rises upward at the end opposite to the base portion 33, i.e., the other side in the thickness direction (right side in Figure 5C). Furthermore, there is a valley portion 35 (see Figure 8) that is recessed downward between the claw portion 32 and the base portion 33. Reference numeral 36 in Figure 8 indicates a guide recess 36 into which a protrusion (see Figure 6) provided on the casing 21 side fits. The movement of the locking member 30 in the vertical direction is guided by the protrusion fitting into the guide recess 36.

[0023] As shown in Figure 5C, the upper surface of the claw portion 32 on the other side in the thickness direction (right side in Figure 5C) is an inclined surface 32a (see Figure 8) that becomes higher towards the one side in the thickness direction (left side in Figure 5C). Also, as shown in Figure 8, both sides of the inclined surface 32a in the width direction are smooth arcuate surfaces 32b. Furthermore, the upper surface of the claw portion 32 is also a smooth arcuate surface 32b.

[0024] The operating member 40 is a integrally molded resin product. As shown in Figure 6, it is composed of a longitudinal member 41 that extends in the width direction, with an elastic member 51 attached to one end in the width direction (left side in Figure 6) and a locking member 30 connected to the other end in the width direction (right side in Figure 6). Furthermore, as shown in Figure 9A, the longitudinal member 41 has a protrusion 41a on one end in the width direction (right side in Figure 9A) to which the elastic member 51 (see Figure 6) is locked. The protrusion 41a protrudes cylindrically from the end face 44 on one end in the width direction (right side in Figure 9A). The elastic member 51 in this embodiment is composed of a coil spring. Furthermore, as shown in Figure 7, one end of the coil spring (left end in Figure 7) is fitted into a protrusion 25a provided on the casing 21. The other end of the coil spring (right end in Figure 7) is fitted into the protrusion 41a of the longitudinal member 41.

[0025] Furthermore, as shown in Figure 9A, the longitudinal member 41 is provided with a pin 42 on the other end in the width direction (left side in Figure 9A) to which the locking member 30 is connected. The pin 42 protrudes cylindrically from the side surface of the longitudinal member 41 slightly toward one end than the end face 43 on the other end in the longitudinal direction (left side in Figure 9A), in a direction perpendicular to the longitudinal direction (a direction perpendicular to the plane of the paper in Figure 9A). The pin 42 constitutes part of the movement direction changing mechanism 50, which will be described later.

[0026] As shown in Figure 6, these operating members 40 and elastic members 51 are housed in a housing section 25 provided in the casing 21. Also, as shown in Figure 5C, the upper part of the base 33 of the locking member 30 is housed in the housing section 25 (see Figure 6), while the lower part of the base 33 and the protruding part 37 protrude below the housing section 25 (see Figure 6).

[0027] Here, as shown in Figure 8, the longitudinal member 41 has a projection 45 extending in the longitudinal direction of the longitudinal member 41 on its upper surface. As shown in Figure 6, the projection 45 (see Figure 8) fits into a longitudinal opening located above the housing 25 (towards the viewer in Figure 6), guiding movement in the width direction (left-right direction in Figure 6). The movement of the operating member 40 in the vertical direction (direction perpendicular to the plane of the paper in Figure 6) is restricted by the casing 21. In this embodiment, the casing 21, along with the locking member 30 and the operating member 40, is made of molded resin, thus reducing the weight of the device.

[0028] As shown in Figure 9A, the movement direction changing mechanism 50 consists of a pin 42 provided on the operating member 40 and a groove 34 provided on the locking member 30. As shown in Figure 8, the groove 34 is formed on the side opposite to the side where the protruding portion 37 of the base portion 33 is formed. The groove 34 has a horizontal groove 34a that is parallel to the direction of movement of the operating member 40, i.e., the lateral direction (left-right direction in Figure 9A), and an inclined groove 34b that is inclined with respect to the lateral direction. The horizontal groove 34a and the inclined groove 34b are connected and continuous at a bend. The pin 42 enters the inclined groove 34b from the horizontal groove 34a and moves within the inclined groove 34b, as shown in Figure 9B, causing the locking member 30 to move in the vertical direction.

[0029] The movement direction changing mechanism 50 is configured with a pin 42 provided on the laterally moving movement member 40 and an inclined groove 34b provided on the locking member 30, allowing for easy control of the vertical movement of the locking member 30. Furthermore, the use of a laterally moving movement member 40 has the advantage of reducing the vertical size of the device, making it compact (thin).

[0030] In this regard, as shown in Figure 1, conventional door stopper devices were large in the vertical direction, so when attaching them to the door D, it was necessary to cut away a part of the side or bottom of the door D to create space (a recess) for attaching the device. However, with this invention, the door-side member 20 is thinner, which has the further advantage that it is not always necessary to cut away the door D to create a recess.

[0031] The operation of locking and unlocking the door D by this door stopper device S will be explained.

[0032] As shown in Figures 2 and 3, when the door D is moved in the opening direction (arrow a direction) and the door-side member 20 is brought closer to the floor-side member 10, the stopper part 12 is attracted by the magnetic force of the magnet 22 and rises from the floor F. When the door D is moved further in the opening direction, as shown in Figures 5A to 5C, the claw part 32 of the locking member 30 fits under the stopper part 12, and the claw part 32 then fits into the locking hole 13, thereby locking the movement of the door D (see Figure 2).

[0033] At this time, as shown in Figure 4, the locking member 30 is biased upward (towards the viewer in Figure 4) by the action of the movement direction changing mechanism 50. This occurs because the movement member 40 is biased laterally by the elastic member 51, that is, in the downward slope direction of the inclined groove 34b as shown in Figure 9A, and as shown in Figure 9B, the locking member 30 is lifted upward by this biasing force. Therefore, as shown in Figure 5C, once the claw portion 32 enters the hole 13, the biasing force of the elastic member 51 (see Figure 4) causes the claw portion 32 that has entered the hole 13 to lift the stopper portion 12, making it difficult for the claw portion 32 to detach from the hole 13.

[0034] However, there is a problem in that it is difficult for the worker to identify the predetermined position when fixing the floor-side member 10 to the floor F. For example, as shown in Figure 1, when the door D is moved to the locked position (a position near the floor-side member 10 in Figure 1) in order to check the fixing position of the floor-side member 10 relative to the locked position of the door D, the fixing position of the floor-side member 10 is located in the narrow space between the locked door D and the wall W, making it difficult for the worker to see. Therefore, fixing the floor-side member 10 to the floor F is difficult. To address this, the door stopper installation unit according to this embodiment uses a door stopper positioning jig 60 to position the fixing location of the floor-side member 10 (see Figure 1) to the floor F, as shown in Figure 10.

[0035] As shown in Figure 15, the door stopper positioning jig 60 consists of a flat plate portion 61 and a pair of rising portions 64 that rise upward from the flat plate portion 61. The flat plate portion 61 is a longitudinally shaped flat plate and, as shown in Figure 13, is formed to be locked to the door-side member 20, along the surface direction of the floor F, and to protrude on both sides in the thickness direction, sandwiching the door D.

[0036] As shown in Figure 15, the flat plate portion 61 has marking portions 62 for marking the fixing position of the floor-side member 10 (see Figure 1). The marking portions 62 are formed on one of the protruding portions 67 on either side of the flat plate portion 61 (the left side in Figure 16A). The marking portions 62 are through holes, and multiple (three in the embodiment) are formed. As shown in Figure 13, the door stopper positioning jig 60 is used by attaching it to the door-side member 20 so that the marking portions 62 are located on the opening side of the door D. The longitudinal end of the protruding portion 67 is formed in an arc shape.

[0037] As shown in Figure 16A, a gripping portion 63 is formed on the protruding portion 66 on the other side (right side in Figure 16A) of the portions that protrude from both sides of the flat plate portion 61. The gripping portion 63 is a rib that protrudes upward from the flat plate portion 61 (towards the viewer in Figure 16A). The gripping portion 63 consists of multiple ribs extending in the short direction of the flat plate portion 61 (a direction perpendicular to the longitudinal direction; vertical direction in Figure 16A) and one rib that extends in the longitudinal direction of the flat plate portion 61 (left-right direction in Figure 16A) and is formed in the center of the short direction. By gripping the gripping portion 63, the door stopper positioning jig 60 can be easily inserted into and removed from the gap between the door D and the floor F (see Figure 10).

[0038] As shown in Figures 16A and 16B, the raised portion 64 extends outward in the short direction (up and down direction in Figure 16A) from both sides of the center of the flat plate portion 61 in the longitudinal direction (left and right direction in Figure 16A), and further extends upward (left side in Figure 16B) from these extended portions. As shown in Figure 16C, a mounting hole 65 extending vertically is formed in the raised portion 64 at the center of the flat plate portion 61 in the longitudinal direction. Here, as shown in Figure 10, the door-side member 20 has projections 24 that extend laterally from both end faces in the width direction when attached to the bottom surface of the door D. The projections 24 also extend in the thickness direction of the door D.

[0039] The raised portion 64 is secured to the door-side member 20 by fitting the projection 24 into the mounting hole 65. In this state, the raised portion 64 can slide vertically relative to the projection 24 via the mounting hole 65. This allows the distance from the door stopper positioning jig 60 to the floor F or ceiling to be freely adjusted. The raised portion 64 is made of an elastically deformable material. For example, materials such as resin, aluminum, paper, or nonwoven fabric can be used. Because the raised portion 64 is elastically deformable, it is easy to attach to and detach from the projection 24.

[0040] Here, as shown in Figures 11A and 11B, Hmin is the minimum gap height between door D and floor F into which the floor-side member 10 (see Figure 2) can be inserted with the door-side member 20 attached to door D. When the gap height between door D and floor F to which the door stopper device S is to be attached is less than Hmin, the raised portion 64 of the door stopper positioning jig 60 cannot be inserted into the gap when the flat plate portion 61 is in contact with floor F, with the upper part hitting door D, as shown in Figure 11C.

[0041] Furthermore, if the distance between the door-side member 20 attached to the door D and the floor-side member 10 attached to the floor F is too great, even if the floor-side member 10 is fixed to the floor F in this state, the two cannot be locked together. As shown in Figures 12A and 12B, if Hmax is the maximum gap height between the door D and the floor F that allows the door-side member 20 attached to the door D and the floor-side member 10 attached to the floor F (see Figure 2) to be locked together, then, when the gap height is greater than a predetermined height Hmax, the raised portion 64 of the door stopper positioning jig 60, when attached to the projection 24, will lift up from the floor F as the projection 24 contacts the upper end 65a of the mounting hole 65 (see Figure 15), as shown in Figure 12C.

[0042] This section describes a method for positioning the fixing position of the floor-side member 10 (see Figure 2) using this door stopper positioning jig 60.

[0043] First, it is checked whether the door stopper device S (see Figure 2) can be attached to the door D and the floor F. As shown in Figure 10, the door stopper positioning jig 60 is moved in the direction of arrow X with the flat plate portion 61 in contact with the floor F, and it is checked whether the raised portion 64 can be inserted into the gap between the door D and the floor F. As shown in Figure 11C, if the raised portion 64 cannot be inserted into the gap between the door D and the floor F, it is determined that the door stopper device S cannot be attached to that gap.

[0044] Next, when the door stopper device S (see Figure 2) is attached to the door D and the floor F, it is checked whether the door-side member 20 and the floor-side member 10 (see Figure 2) can be locked together. As shown in Figure 10, the door-side member 20 is attached to the bottom surface of the door D. The projection 24 of the door-side member 20 is fitted into the mounting hole 65 so that the marking portion 62 is positioned on the opening side of the door D with the door D in between, and the door stopper positioning jig 60 is locked to the door-side member 20. At this time, as shown in Figure 12C, it is checked whether the door stopper positioning jig 60 is not floating above the floor F with the projection 24 in contact with the upper end 65a (see Figure 15) of the mounting hole 65. If the door stopper positioning jig 60 is lifted off the floor F, the door-side member 20 and the floor-side member 10 (see Figure 2) cannot be engaged with the door D and the floor F respectively, and it is determined that the door stopper device S (see Figure 2) cannot be applied to that door D.

[0045] The door stopper device S (see Figure 2) is checked for installation and locking using the door stopper positioning jig 60 described above. After it is determined that there are no problems with installation, the floor-side member 10 (see Figure 2) is positioned at its fixed location. As shown in Figure 13, with the door stopper positioning jig 60 attached to the door-side member 20, the door D is moved in the opening direction (direction of arrow Y) to the locked position. Next, with the door D in the locked position, the door stopper positioning jig 60 is pressed against the floor F and removed from the projection 24, ensuring that the position of the door stopper positioning jig 60 does not shift. Then, as shown in Figure 14, the door D is moved in the closing direction (direction of arrow Z), moving the door D away from the locked position to secure working space at the locked position.

[0046] Then, with the door stopper positioning jig 60 pressed against the floor F, the fixing position of the floor-side member 10 (see Figure 2) is marked on the floor F via the marking portion 62 using a pencil or scribing needle. This allows the fixing position of the floor-side member 10 (see Figure 2) to be determined. After that, the door stopper positioning jig 60 is removed from the floor F, and the floor-side member 10 (see Figure 2) is attached to the floor F according to the marked portion.

[0047] As described above, with the door stopper installation unit of this embodiment, as shown in Figure 10, it is easy to determine whether the door stopper device S (see Figure 2) can be installed in the gap between the door D and the floor F by using the door stopper positioning jig 60. It is also easy to determine whether the installed door stopper devices S can engage with each other. If it is discovered after installing the door stopper device S (see Figure 2) that the floor-side member 10 (see Figure 2) does not fit into the gap, or that the door-side member 20 and the floor-side member 10 (see Figure 2) do not engage, it would be troublesome to have to remove the door stopper device S (see Figure 2) that has already been installed. However, by performing a simple installation check in advance, this trouble can be eliminated.

[0048] Furthermore, the door stopper positioning jig 60 is locked to the door-side member 20 and protrudes on the opening side of the door D, and a marking portion 62 is provided on the protruding portion. Therefore, the fixing position of the floor-side member 10 (see Figure 2) can be marked even when the door stopper positioning jig 60 is attached to the door D. As a result, there is no risk of the door stopper positioning jig 60 shifting position, and the marking can be done in an accurate position.

[0049] In the above embodiment, the floor-side member 10 (see Figure 2) was attached to the floor F, but the configuration can also be adopted in which the floor-side member 10 (see Figure 2) is attached to the ceiling. Also, in the above embodiment, a coil spring was used as the elastic member 51, but the elastic member 51 may be made of a spring other than a coil spring, for example, a leaf spring. Furthermore, in the above embodiment, the configuration of the present invention was explained using as an example a door stopper positioning jig 60 that targets the door-side member 20 fixed to the bottom surface of the door D, and a door stopper installation unit which is a set of the door stopper positioning jig 60, the floor-side member 10 (door stopper part 10), and the door-side member 20, but the door-side member 20 may be fixed to the side surface of the door D.

[0050] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
