Description

[Technical Field]

[0001] This invention relates to a door stopper that prevents a door that opens and closes a passageway or storage space from opening any further than a predetermined opening position, a door stopper positioning method that fixes a member that is fixed to the door side of the door stopper and a member that is fixed to the floor side of the door stopper in appropriate positions, and a door stopper positioning jig used in this method. [Background technology]

[0002] BACKGROUND ART Door stoppers that restrict a door that opens and closes a passageway or a storage space from opening further to a predetermined opening position are disclosed in, for example, Patent Documents 1 to 3.

[0003] The door stopper described in Patent Document 1 restricts the opening angle of the door so that it cannot be opened any further by abutting a retained part fixed to the door against a door stop part fixed to the floor.The door is locked in the open position by magnetically attracting the door stop part on the floor side to the retained part on the door side, or by locking the retained part on the door side with a retaining part (latch) provided on the door stop part on the floor side.

[0004] Furthermore, the door stoppers described in Patent Documents 2 and 3 have a stopper body provided on the floor side and a claw portion provided on the door side, and when the door reaches a predetermined opening position, the magnetic force of the magnet provided on the door side pulls up the stopper body on the floor side, engaging the claw portion with the stopper body, thereby locking the door so that it cannot move to the open or closed side.

[0005] In the various door stoppers described above, a door-side member fixed to the door and a floor-side member fixed to the floor cooperate to lock the door in the opening and closing direction by adhering or engaging with each other. To perform this function, the door-side member and the floor-side member must be fixed to the door and floor, respectively, so that they face each other or abut each other when the door is opened to a predetermined opening angle (hereinafter referred to as the locked opening angle). However, when the door is in the locked opening angle, it can be difficult to grasp the relative positions of the door-side member and the floor-side member.

[0006] For example, there is a case where the installation position of the floor-side component is close to the wall. In such a case, when the door is opened to the locked position to bring the door-side component and the floor-side component closer together, the location where the floor-side component should be fixed ends up being on the back side of the door (the side facing the wall), which is difficult for the worker to see. For this reason, workers have had to reach into a narrow, hard-to-see space on the back side of the door and mark the locations where the door-side component and the floor-side component should be fixed on the back side of the door and the floor with a pencil or scribe. Working in such a narrow, hard-to-see space is very complicated, and because the work is done in a blind spot on the back side of the door, it is easy for the position to be misaligned.

[0007] A method for solving this problem is proposed in Patent Document 4. Using a first piece having a lateral extension and a door attachment portion via a first bend, and a second piece having a floor-mounted portion and an undulating portion via a second bend, the method includes the steps of attaching the door attachment portion to the back surface of the door so that the lateral extension extends from the gap between the door and the floor toward the front surface of the door, inserting the floor-mounted portion between the lateral extension and the floor so that the undulating portion extending from the floor-mounted portion abuts against the tip of the lateral extension, rotating the undulating portion extending from the floor-mounted portion via the second bend to attach it to the floor, and marking the positions corresponding to the door markings on the door attachment portion on the back surface and the positions corresponding to the floor markings on the floor-mounted portion on the floor. After marking, both the first and second pieces are peeled off. Pilot holes for screws are drilled at each of the marked locations. The door-side and floor-side components that make up the door stop are fixed in place with screws. This makes it possible to easily and accurately attach the door-side and floor-side components of the door stopper to the door and floor, even when the floor-side component is installed close to the wall.

[Figure 17] Section XVII-XVII of Figure 16 DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows a state in which a door stopper A is used for a so-called swing door, in which a door 1 is fixed to a wall W or a pillar with a hinge 3. By pulling or pushing a knob 2, the door 1 rotates around the rotation axis of the hinge 3, allowing the passage to be opened or closed.

[0018] The door stopper A of this embodiment includes a floor-side member 20 (door-stopping portion) provided on the floor F side, and a door-side member 10 (held portion) provided on the door 1 side. As shown in Figs. 2 and 3, the door-side member 10 is fixed by a fixing adhesive portion 15 to the vicinity of the lower end of the back surface 1b of the front surface 1a facing the closing side of the door 1 and the back surface 1b facing the opening side. Also, as shown in Fig. 3, when the hinged door 1 is opened to a predetermined opening angle, the floor-side member 20 is fixed by a fixing adhesive portion 25 to the floor F slightly on the opening side of the back surface 1b of the door 1 at the predetermined opening angle (closer to the wall W than the back surface 1b).

[0019] As shown by arrow a in FIG. 2, when the door 1 moves in the opening direction and reaches the predetermined opening angle indicated by the dashed line in the figure, the magnetic force of the magnet 11 provided on the door-side member 10 pulls the claw 22 of the floor-side member 20 up from the base plate 21 as shown by arrow b, as shown in FIG. 3. One end of the claw 22 is supported by a holder 23 fixed to the base plate 21, and the other end is pulled up. At this time, the claw 22 of the floor-side member 20 engages with the locking piece 12 of the door-side member 10, locking the door 1 so that it is difficult to move to the open or closed side. This predetermined opening angle at which the door 1 is restricted from opening or closing is hereinafter referred to as the locked opening angle. To release this lock, the door 1, which is at the locked opening angle, is pulled strongly in the opening direction, pushing down the locking piece 12 and releasing its engagement with the claw 22.

[0020] The floor-side member 20 of this door stopper A is fixed to the floor F by a fixing adhesive portion 25. The fixing location of the floor-side member 20 is located on the back surface 1b side of the door 1 when the door 1 is in the locked position, i.e., in the narrow space between the wall W and the back surface 1b. The door-side member 10 is also fixed to the back surface 1b of the door 1 by a fixing adhesive portion 15. The fixing location of the door-side member 10 is located on the back surface 1b of the door 1 in a position facing the floor-side member 20. Therefore, when the door 1 is opened to the locked position to bring the door-side member 10 and the floor-side member 20 closer together, the position where the floor-side member 20 should be fixed is on the back surface side of the door 1 (the side facing the wall W), which is difficult for the worker to see. Furthermore, the position where the door-side member 10 should be fixed is also on the back surface side of the door 1, which is difficult for the worker to see. This creates a work environment where it is difficult to determine the positions where the door-side member 10 and the floor-side member 20 should be fixed.

[0021] Therefore, in this invention, a door stopper positioning jig B is used, which consists of a first piece 30 that positions the fixing location of the door side member 10 to the door 1, as shown in Figures 4(a) and (b), and a second piece 40 that positions the fixing location of the floor side member 20 to the floor F, as shown in Figures 5(a) and (b).

[0022] In this embodiment, the first piece 30 and the second piece 40 are each a flexible (foldable) sheet-like member. In this embodiment, cardboard is used as the material, but other paper materials such as corrugated cardboard may also be used. Furthermore, as long as the material is flexible, the sheet-like member may be made of resin, metal, or other suitable material. However, it is desirable that the material be such that, after a certain portion is bent, that portion does not return to its original state but rather can maintain its shape at that position. In particular, it is desirable that the material be rigid enough that the bent portion can stand on its own.

[0023] As shown in FIGS. 4(a) and 4(b), the first piece 30 is a single sheet-like member 31 having a horizontal protrusion 33 and a door attachment portion 34 via a first bending portion 32 (hereinafter referred to as the first fold line 32 in this embodiment). The horizontal protrusion 33 and the door attachment portion 34 are bendable via the first fold line 32. The door attachment portion 34 is provided with a door-side positioning portion 35 corresponding to the position where the door-side member 10 is attached. In addition, to facilitate folding along the first fold line 32, a lightening portion 38 is provided by hollowing out the piece midway along the second fold line. FIG. 4(a) shows the front surface 31a, and FIG. 4(b) shows the back surface 31b. In this embodiment, the front surface refers to the surface located on the top side, and the back surface refers to the surface located on the bottom side. In the first piece 30, the side of the lateral protrusion 33 that faces the top surface when in use is called the front surface 31a, and this surface is the surface that faces the rear surface 1b of the door and is attached thereto.

[0024] As shown in Figures 6 and 7, the first piece 30 is used by bending the lateral extension 33 and the door attachment portion 34 at right angles via the first fold line 32 and the lightening portion 38, and then attaching the door attachment portion 34 to the back surface 1b of the door 1. Attachment is performed using an adhesive portion 37 provided on the surface 31a side of the door attachment portion 34. The adhesive portion 37 is made of double-sided tape. The double-sided tape is used after peeling off a protective sheet (not shown).

[0025] At this time, the lateral protrusion 33 protrudes from the gap between the bottom surface 1c of the door 1 and the floor F towards the front surface 1a of the door 1. In other words, the protrusion length from the first fold line 32 to the tip 33a of the lateral protrusion 33 is equal to or greater than the thickness T between the front surface 1a and the back surface 1b of the door 1. In this embodiment, the lateral protrusion 33 is placed on the floor F, but there may be a gap between the lateral protrusion 33 and the floor F partially or entirely.

[0026] As shown in Figures 5(a) and 5(b), the second piece 40 is a single sheet-like member 41 having a floor-mounted portion 43 and an undulating portion 44 via a second bend 42 (hereinafter referred to as the second fold line 42 in this embodiment). The floor-mounted portion 43 and the undulating portion 44 are bendable via the second fold line 42. Figure 5(a) shows the front surface 41a side, and Figure 5(b) shows the back surface 41b side.

[0027] As shown in FIGS. 8 to 11 , the second piece 40 is used by bending the floor-mounted portion 43 and the undulating portion 44 at a right angle along the second fold line 42, and then inserting the floor-mounted portion 43 between the horizontally extending portion 33 of the first piece 30 and the floor F. At this time, the undulating portion 44 stands upright from the floor-mounted portion 43 along the second fold line 42. The undulating portion 44 abuts against the tip 33a of the horizontally extending portion 33 of the first piece 30. With the undulating portion 44 abutting against the tip 33a of the horizontally extending portion 33 of the first piece 30, the tip 43a of the floor-mounted portion 43 extends further toward the wall W than the door attachment portion 34 of the first piece 30.

[0028] At this time, positioning in the left-right direction can be achieved by overlapping the first piece 30 and the second piece 40 with the same left-right width. For this reason, it is desirable to make the widths of the first piece 30 and the second piece 40 the same.

[0029] The undulating portion 44, which stands up from the floor-mounting portion 43, can rotate via the second fold line 42, and when the surface direction of the undulating portion 44 becomes parallel to the floor F by this rotation, it is attached to the floor F. Attachment is performed using an adhesive portion 47 provided on the back surface 41b of the undulating portion 44. The adhesive portion 47 is made of double-sided tape. The double-sided tape can be used after removing the protective sheet (not shown). Note that the work of attaching the undulating portion 44 to the floor F must be performed with the door 1 in the locked open position.

[0030] As shown in FIG. 12 , the floor mounting portion 43 is provided with a floor-side positioning portion 45. In this embodiment, the floor-side positioning portion 45 is formed as an opening that is surrounded on all four sides by a floor-side mounting frame 46 and penetrates from the front surface 41 a to the back surface 41 b. The inside of the edge of the opening on the floor surface corresponds to the floor-side mounting area 6 where the floor-side component 20 is attached. The shape and size of the floor-side mounting area 6 surrounded by the floor-side mounting frame 46 match the planar shape and size of the floor-side component 20, allowing the fixing location of the floor-side component 20 to be identified. Furthermore, as shown in FIG. 13 , the door attachment portion 34 is provided with a door-side positioning portion 35. In this embodiment, the door-side positioning portion 35 is formed as an opening that is surrounded on all four sides by the door-side mounting frame 36 and penetrates from the front surface 31 a to the back surface 31 b. The inside of the edge of the opening on the back surface 1 b of the door 1 corresponds to the door-side mounting area 5 where the door-side component 10 is attached. The shape and size of the door-side mounting area 5 surrounded by the door-side mounting frame 36 match the planar shape and size of the door-side component 10, making it possible to identify the fixing location of the door-side component 10. When the first piece 30 and the second piece 40 are installed with their left-right positions aligned, the floor-side positioning part 45 and the door-side positioning part 35 are also arranged so that their left-right positions are aligned.

[0031] In the above embodiment, the door-side positioning portion 35 is a hole that penetrates the door attachment portion 34 from front to back, or in an embodiment, it may be a notch cut into any edge of the door attachment portion 34. In either embodiment, its position corresponds to the position where the door side member 10 is fixed to the door 1 (door side attachment area 5), ​​and positioning can be easily and accurately achieved by aligning the edge of the hole or notch with the edge of the door side member 10 when attaching. Furthermore, in the above embodiment, the floor-side positioning portion 45 is a hole that penetrates the floor-surface mounting portion 43 from front to back, or in an embodiment, it may be a notch cut into any edge of the floor-surface mounting portion 43 when attaching. In either embodiment, its position corresponds to the position where the floor side member 20 is fixed to the floor F (floor-side attachment area 6), and positioning can be easily and accurately achieved by aligning the edge of the hole or notch with the edge of the floor side member 20 when attaching.

[0032] The method for positioning the door stopper using this door stopper positioning jig B and the method for fixing the door stopper will be described below.

[0033] First, there is the process of attaching the first piece 30 configured as described above to the door 1. As shown by arrow a in FIG. 6, the door 1 is moved in the opening direction, and at an opening position that is convenient for the work, the first piece 30 is inserted into the door 1 in the direction of arrow c. Here, the lateral extension portion 33 and the door attachment portion 34 are bent at a right angle along the first fold line 32, and the door attachment portion 34 is attached to the back surface 1b of the door 1. The attachment point is set at the location where the door side component 10 is to be fixed. In this state, as shown in FIG. 7, the lateral extension portion 33 is caused to extend from the gap between the door 1 and the floor F toward the front surface 1a of the door 1.

[0034] Next, the second piece 40 having the above-described configuration is placed in a predetermined position on the floor F. As shown in FIG. 8 , the door 1 is further moved in the opening direction, and the second piece 40 is inserted into the door 1 in the direction of arrow d at a position where the door 1 is locked by the door stopper (the locked opening). Here, the floor-mounted portion 43 and the undulating portion 44 are bent at a right angle along the second fold line 42, and the undulating portion 44 standing up from the floor-mounted portion 43 is brought into contact with the tip 33a of the lateral extension 33. Note that the operation of inserting the floor-mounted portion 43 under the first piece 30 and bringing the undulating portion 44 into contact with the tip 33a of the lateral extension 33 may be performed at a position of any opening angle of the door 1 (for example, the position shown in FIG. 6 ), and then the door 1 may be moved to the locked opening while maintaining the undulating portion 44 in contact with the tip 33a of the lateral extension 33.

[0035] The next step is to attach the second piece 40 to the floor F. As shown by arrow e in Figure 10, the undulating portion 44, which stands up from the floor-mounting portion 43, is rotated via the second fold line 42 to a horizontal position, i.e., parallel to the floor F. Then, as shown in Figure 11, the undulating portion 44 is attached to the floor F.

[0036] This completes the process of specifying the fixing locations (door-side mounting area 5 and floor-side mounting area 6) of the door-side member 10 and the floor-side member 20. As shown in Fig. 12, after the opening angle of the door 1 is moved in the closing direction, the door-side members 10 are attached to the door-side mounting areas 5 and the floor-side member 20 is attached to the floor-side mounting area 6.

[0037] A door side component 10 of a corresponding shape and size is fixed to the exposed portion of the back surface 1b of the door 1, shown as the door-side mounting area 5 in FIG. 13(a). As shown in FIG. 13(b), a fixing adhesive portion 15 made of double-sided tape is attached to a portion of the mounting surface 14 of the door side component 10. In other embodiments, the fixing adhesive portion 15 may be attached to the entire mounting surface 14, or the component may be fixed by screws instead of double-sided tape. However, double-sided tape is easier to use for positioning. When using double-sided tape, the protective sheet (not shown) is peeled off immediately before installation, and the adhesive surface of the fixing adhesive portion 15 is attached to the back surface 1b of the door 1 to fix the door side component 10. Once attached, the component will look like the one shown in FIG. 14. After this, the first piece 30 is peeled off, completing the door side configuration for use shown in FIG. 1. Furthermore, it is more preferable to attach and position the door side member 10 with double-sided tape, and then fasten the door side member 10 to the door 1 more firmly by screwing it through the screw holes 17 of the door side member 10.

[0038] On the other hand, in the second piece 40 attached to the floor F, the flaps 49 provided on the left and right sides of the floor-side positioning portion 45 are raised as shown in FIG. 15(a). By raising the flaps 49 on both sides, the entire floor-side mounting area 6 to which the floor-side component 20 is to be attached is exposed, and the floor-side component 20 is less likely to shift position when being fixed, improving workability. The floor-side component 20 of the corresponding shape and size is fixed to the exposed portion of the floor F, shown as the floor-side mounting area 6, which is expanded by raising the flaps 49. As shown in FIG. 15(b), a fixing adhesive portion 25 made of double-sided tape is attached to a portion of the bottom surface of the floor-side component 20. The fixing adhesive portion 25 may be attached to the entire surface, or may be fixed by screws or other fasteners instead of double-sided tape. However, using double-sided tape for positioning is easier. When using double-sided tape, the protective sheet (not shown) is peeled off immediately before installation, and the adhesive surface of the adhesive fixing portion 25 is attached to the floor F to secure the floor-side component 20. Once secured, the component will be in the state shown in the perspective view of FIG. 16 and the cross-sectional view of FIG. 17. If the floor-side component 20 is misaligned, the claw portion 22 will be misaligned, preventing the door stopper A from operating properly. However, in this embodiment, the flap portion 49 acts as a guide for the left and right positions, as shown in the cross-sectional view of FIG. 17. This prevents the floor-side component 20 from shifting out of position, facilitating accurate installation. After this, the second piece 40 is peeled off from the floor F, completing the floor-side configuration shown in FIG. 1 for use. Furthermore, after attaching and positioning the floor-side component 20 with the double-sided tape, it is preferable to further secure the floor-side component 20 to the floor F by fastening screws through the screw holes 27 of the floor-side component 20.

[0039] In the above embodiment, the first piece 30 is configured such that the lateral extension 33 and the door attachment portion 34 are bendable via the first bend 32 (first fold line 32), and the flat first piece 30 is used after being deformed to bend via the first bend 32, but this is not limited to this embodiment. For example, it is also possible to use a first piece 30 made of resin or metal, in which the lateral extension 33 and the door attachment portion 34 are molded in advance into a bent state via the first bend 32 or are maintained in a bent state. Furthermore, it is also possible to adopt a configuration in which the first piece 30 is attached in an appropriate position in advance when the door 1 is shipped or delivered.

[0040] Similarly, in the above embodiment, the second piece 40 has the floor-mounting portion 43 and the undulating portion 44 bendable via the second bend 42 (second fold line 42), and is used after the flat second piece 40 is deformed to bend via the second bend 42. However, this is not limited to this embodiment. For example, it is also possible to use a second piece 40 made of resin or metal, in which the floor-mounting portion 43 and the undulating portion 44 are molded in advance into a bent state via the second bend 42 or are maintained in a bent state. However, the second piece 40 needs to be made of a flexible material that allows the floor-mounting portion 43 and the undulating portion 44 to rotate at the second bend 42 so that the floor-mounting portion 43 and the undulating portion 44 are flush with each other (in a flat state), or the second bend 42 needs to have a structure that allows such rotation (for example, a hinge structure, etc.).

[0041] Furthermore, in the above embodiment, the door stopper A is one in which the claw portion 22 of the floor-side member 20 engages with the locking piece 12 of the door-side member 10, as shown in Figures 1 to 3. However, the door stopper A is not limited to the form shown in Figures 1 to 3, and the present invention can also be applied to various door stoppers that restrict the movement of the door 1 in the opening direction or the closing direction to a predetermined opening degree.
