Summary of the Invention
Problems to be Solved by the Invention
[0004] However, in the finger-catching preventer for a door of Patent Document 1, the door-stop attachment portion is attached along the surface of the door-stop of the opening frame, and when the door is opened or closed, a gap into which a finger can be inserted occurs between the door-stop protruding from the inner peripheral surface of the opening frame and the bottom edge on the hanging side of the door, so there is a problem that the possibility of finger-catching cannot be suppressed.
[0005] An object of the present disclosure is to provide a gap filler that can suppress the occurrence of a gap between a frame body provided in an opening and a door body provided inside the frame body.
Means for Solving the Problems
[0006] This disclosure relates to a gap-filling material for filling the gap between a door-end vertical frame constituting a frame provided in an opening in a building and a door body rotatably supported by the frame and capable of opening and closing the opening, wherein the vertical frame is formed from the lower end to the upper end of the visible surface and has a mounting groove portion to which a door stop protruding toward the door body is attached, and is attached to the mounting groove portion to which a door stop is not attached in whole or in part, and is embedded so as to be substantially flush with the visible surface of the vertical frame and has a visible width substantially the same as the visible width of the mounting groove portion, a long second mounting member installed on the visible surface of the door-end side of the door body, and a closing member made of a surface material that connects the first mounting member and the second mounting member and fills the gap between the door-end vertical frame and the door body. [Brief explanation of the drawing]

[Figure 10] This is a schematic diagram showing how a door closes within a frame equipped with a door stopper. [Modes for carrying out the invention]
[0008] Embodiments of this disclosure will be described in detail below with reference to the drawings. In this specification, "face direction" refers to the direction of the surface of a door body fitted into an opening formed in a building, and "depth direction" refers to the direction of the thickness of the door body. In the drawings of this specification, the "door opening / closing side" where the door body is rotatably supported by the frame on the door-end side and opens and closes is denoted as X1, and the "door stop side" where the door body abuts against a door stop provided on the frame and the opening and closing of the door body is restricted is denoted as X2.
[0009] As shown in Figures 1 to 3, the gap-sealing material 1 of this embodiment is attached to the door 10, and the door 10 is equipped with the gap-sealing material 1. The door 10 has a frame 2, a door stop 3, and a door body 4. As shown in Figure 3, the door body 4 is rotatable in the X2 direction, but the door body opening / closing side X1 and the door stop side X2 can be any space that constitutes the interior of the room. For example, the use of the space is not limited to a living room, corridor, or sanitary space. In Figure 2, in the diagram within the dashed line that shows an enlarged view of the lower part of the gap-sealing material 1, the cover material 13, which will be described later, is represented by a dashed line. Also in Figure 2, the door body 4 is represented by a dashed line.
[0010] The gap filler 1 of the present disclosure is installed for the purpose of preventing a particularly small child from inserting their hand into the gap between the vertical frame 22 on the X1 side and the door body 4 towards the door jamb side when the door body 4 is opened and closed. As shown in FIG. 10, when the open door body 4 abuts against the door stop 3 and enters the closed state, a gap S1 indicated by a substantially triangular two-dot chain line occurs between the door stop 3 provided on the vertical frame 22 and the door body 4. The occurrence of this gap S1 increases the chance that the door body 4 will be closed without noticing that a child's hand has been inserted between the door body 4 and the door stop 3. The gap filler 1 can suppress the occurrence of this gap S1.
[0011] As shown in FIG. 1, the frame body 2 is provided in the opening 20 of the wall surface W. The frame body 2 is configured by framing an upper frame 21 and vertical frames 22 and 23 arranged in the left-right direction in a substantially C shape. The frame body 2 includes a mounting groove portion 222 and a door stop 3. The door stop 3 is configured by framing an upper door stop 31 and vertical door stops 32 and 33 arranged in the left-right direction in a substantially C shape. As shown in FIGS. 7A to 6C, the mounting groove portion 222 is formed to extend from the lower end to the upper end of the prospective surface of the frame body 2, and the door stop 3 is embedded and attached in the mounting groove portion 222.
[0012] As shown in FIGS. 1 and 7C, the vertical frame 22 includes a vertical door stop 32 attached to a part of the upper side of the prospective surface of the vertical frame 22 and protruding toward the door body 4 side. The door body 4 is provided indoors, includes a plurality of concealed hinges 41 on the vertical frame 22 of the frame body 2, and is a single-opening door that is rotatably supported by the vertical frame 22 and can open and close the opening 20. The door body of the present disclosure is not limited to this, and the gap filler 1 may be provided not only on a single-opening door but also, for example, on the door jamb side of a double-opening door.
[0013] As shown in FIGS. 1 to 3, the gap filler 1 has a long first attachment member 11 and second attachment member 12, and a cover material 1 (13). The first attachment member 11 is fixed to the vertical frame 22 and has a pair of frame-side end members 111, 111 provided at the upper and lower ends of the first attachment member 11 in the vertical direction, and a cover attachment frame 112. The frame-side end members 111 are attached to both ends of the cover attachment frame 112 so as to be vertically symmetric.
[0014] As shown in FIG. 4, the frame-side end member 111 has a main body portion 111a, a protruding portion 111b, and a protruding piece 111c. The main body portion 111a has a screw hole H11, and by fixing a pair of frame-side end members 111, 111 with a fastening member such as a screw SC1 through the screw hole H11, the first attachment member 11 can be fixed to the prospective surface of the vertical frame 22. In FIG. 4, the cover attachment frame 112 is represented by a two-dot chain line.
[0015] As shown in FIG. 7A, the protruding portion 111b is formed such that its prospective width is substantially the same as the prospective width of the attachment groove portion 222, is provided so as to protrude in the outer peripheral direction of the frame body 2, and is embedded in the attachment groove portion 222 without a gap. With this configuration, by attaching the first attachment member 11 to the vertical frame 22, the attachment groove portion 222 can be completely shielded, and the design and safety of the gap filler 1 can be improved.
[0016] As shown in FIG. 4, the protruding piece 111c is a substantially rectangular protrusion provided to protrude from the protruding portion 111b. The cover attachment frame 112 is a substantially C-shaped long member engaged with the protruding piece 111c, and can sandwich a cover material 13 described later by a movable portion 112a. The cover attachment frame of the present disclosure is not limited to this shape. For example, the cover material 13 may be fixed to the attachment frame by a surface fastener or the like without providing the movable portion 112a.
[0017] As shown in FIG. 7B, the cover attachment frame 112 of the first attachment member 11 is formed such that its prospective width is substantially the same as the prospective width of the attachment groove portion 222, is attached to the attachment groove portion 222 where the door stop 3 is not attached, and is embedded without a gap so as to be substantially flush with the prospective surface of the vertical frame 22. With this configuration, the attachment groove portion 222 can be completely shielded, and the design and safety of the gap filler 1 can be improved.
[0018] Furthermore, in areas where the gap between the vertical frame 22 and the door body 4 is sealed by the cover material 13, there are no members that protrude inward from the vertical frame 22, such as the door stopper 3, thus eliminating obstacles within reach of children. As shown in Figure 8B, since there is no door stopper 3 on the vertical frame 22 and no gap S1 is created between it and the door body 4, the safety of the door 10 can be improved.
[0019] As shown in Figures 1 to 3, the second mounting member 12 is installed on the X1 side facing surface of the door body 4, and has a pair of door body side end members 120, 120 provided at the vertical ends of the second mounting member 12, and a cover mounting frame 123. The door body side end members 120 are attached to both ends of the cover mounting frame 123 in an upward and downward symmetrical manner. As shown in Figure 5, the door body side end member 120 has a main body portion 121 and an extension member 122. In Figures 5 and 6, the cover mounting frame 123 is represented by a dashed line.
[0020] As shown in Figure 6, the main body 121 and the extension member 122 are fixed together to the door body 4 for use. Returning to Figure 5, the main body 121 has a recess 121a parallel to the visible surface of the door body 4 and a projection 121b. The projection 121b is the same as the projection 111c of the frame-side end member 111, so its explanation is omitted.
[0021] The extension member 122 is a roughly L-shaped plate material and has a fixed portion 122a parallel to the visible surface of the door body 4 and an extension portion 122b formed by bending approximately right-angle from the fixed portion 122a. The fixed portion 122a has a screw hole H122 and is fixed to the main body portion 121 via a screw SC2.
[0022] The extension portion 122b has a screw hole H12, and as shown in Figure 6, the extension portion 122b extending to the end of the door body 4 is fixed to the end of the door body 4 via a fastening member, the screw SC3, thereby fixing the second mounting member 12 to the door body 4. With this configuration, the marks left by inserting the screw SC3 after removing the gap-filling material 1 are not noticeable, and no traces are left on the visible surface of the door body 4, so there is no need to apply a decorative sheet or perform other work after removing the gap-filling material 1.
[0023] The gap-filling material 1 is installed with particular consideration for the safety of young children, and it is expected that it will be removed mainly for aesthetic reasons after the children have grown up. For this reason, it is conceivable to use an adhesive such as double-sided adhesive tape for temporary holding to fix the second mounting member 12 to the door body 4. However, in many cases the door body is covered with a surface decorative sheet such as an FK sheet, and in such cases, there is a risk that part of the decorative sheet will peel off along with the adhesive attached to the second mounting member 12.
[0024] According to the door body side end member 120 of this embodiment, the gap-filling material 1 can be attached and detached very easily without damaging the surface material of the door body 4. The extension portion 122b of this embodiment is fixed to the end of the door body 4 on the tail end side, but the disclosure is not limited thereto. For example, the extension portion 122b may be provided and fixed to the end of the door body 4. The extension portion 122b may be provided at any location on the end of the door body 4 to fix the second mounting member 12.
[0025] The cover mounting frame 123 has a movable part 123a. The cover mounting frame 123 and the movable part 123a are identical to the cover mounting frame 112 and the movable part 112a of the first mounting member 11, so their description is omitted. Also, similar to the cover mounting frame 112, the cover mounting frame of the second mounting member 12 of this disclosure is not limited to this shape, and for example, the cover material 13 may be fixed to the mounting frame by hook and loop fasteners or the like without providing the movable part 123a.
[0026] As shown in Figures 2 and 3, the cover material 13 is a closing member that seals the gap between the door frame 22 on the door edge side and the door body 4, and is made of a flexible surface material. The cover material 13 has its ends in the width direction fixed to the first mounting member 11 and the second mounting member 12, and can seal the gap that occurs between the door frame 22 and the door body 4 while flexibly deforming in accordance with the opening and closing operation of the door body 4.
[0027] The length of the gap-filling material 1 can be freely set by adjusting the lengths of the cover mounting frame 112 of the first mounting member 11, the cover mounting frame 113 of the second mounting member 12, and the cover material 13. For example, when installing with consideration for the safety of infants, the gap-filling material 1 may be provided only at the bottom of the vertical frame 22, or when installing with consideration for the safety of adults such as the elderly, the gap-filling material 1 may be provided to cover up to the top of the vertical frame 22. The height of the gap-filling material 1 can be freely adjusted according to the purpose.
[0028] Next, the operation of the gap-sealing material 1 in accordance with the opening and closing operation of the door 4 will be described. As shown in Figures 3 and 7B, when the door 4 is open, the cover material 13 reliably seals the gap between the vertical frame 22 and the door 4. Furthermore, even if the flexible cover material 13 is intentionally pushed by hand, there is no vertical door stop 32 in the area of the vertical frame 22 where the cover material 13 is provided, and the cover mounting frame 112 is embedded so as to be approximately flush with the visible surface of the vertical frame 22, thereby improving the safety of the joinery 10.
[0029] Furthermore, as shown in Figure 7C, by providing the concealed hinge 41, only a small gap S2 is created between the vertical frame 22 and the door panel 4 on the X2 side, making it impossible to insert a finger. Providing the concealed hinge 41 is a more preferred embodiment and can further improve the safety of the joinery 10, but the hinges of this disclosure are not limited to concealed hinges. For example, a flat hinge with the hinge axis protruding on the X2 side may be used for the door panel 4, and in that case as well, the safety on the X1 side when closing the door can be sufficiently ensured by the gap-filling material 1.
[0030] Next, we will describe the state in which the door 4 is rotated to close. As shown in Figure 8A, the frame-side end member 111 of the first mounting member 11 and the door-side end member 120 of the second mounting member 12 approach each other as the door 4 rotates. However, since the frame-side end member 111 and the door-side end member 120 are provided at the vertical ends of the first mounting member 11 and the second mounting member 12, the possibility of a hand being inserted into this gap is extremely low.
[0031] As shown in Figure 8B, there is no vertical door stop 32 in the area of the vertical frame 22 where the cover material 13 is provided, and the cover mounting frame 112 is embedded so as to be substantially flush with the visible surface of the vertical frame 22. With this configuration, even if the cover material 13 is intentionally pushed by hand, the substantially triangular gap S1 shown in Figure 10 does not occur, thus preventing a hand from being inserted between the obstruction protruding from the vertical frame 22 and the door body 4. Furthermore, as shown in Figure 8C, due to the effect of the concealed hinge 41, it is not possible to insert a finger between the vertical frame 22 and the door body 4 from the X2 direction, so the door body 4 can be closed safely.
[0032] Next, the closed state of the door body 4 will be described. As shown in Figure 9A, the frame-side end member 111 and the door body-side end member 120 are provided at the vertical ends of the first mounting member 11 and the second mounting member 12, so that the door body 4 can be closed safely. Also, as shown in Figures 2 and 9B, the cover material 13 deforms flexibly and is loosely folded and stored so as to protrude toward the X1 side. As shown in Figure 9C, the vertical door stop 32 of the vertical frame 22 does not interfere with the second mounting member 12 provided on the door body 4, so that the door body 4 can smoothly abut against the door stop 3.
[0033] As described above, with the gap-filling material 1, there is no need to fold the cover material 13 in multiple places when opening or closing the door. The cover material 13 deforms flexibly in conjunction with the rotation of the door body 4, thus not putting any strain on the opening and closing operation of the door body 4 and improving the operability of the gap-filling material 1. Furthermore, this configuration allows the cover material 13 to have a simple surface appearance, improving the aesthetic design of the gap-filling material 1.
[0034] Next, the installation method for the gap-filling material 1 will be explained. As mentioned above, the gap-filling material 1 is used as needed and is attached to the joinery 10 afterwards. As shown in Figure 1, the first mounting member 11 attached to the vertical frame 22 is installed in contact with the floor surface F, similar to the vertical frame 22.
[0035] First, a portion of the lower side of the existing vertical door stopper 32 on the vertical frame 22 is pre-cut to match the length of the gap-filling material 1 and removed. It is preferable to store the removed portion of the vertical door stopper 32, as it can be reinstalled if the gap-filling material 1 is no longer needed. With the vertical door stopper 32 removed, the mounting groove portion 222 of the vertical frame 22 is exposed.
[0036] Next, the lower end surface of the frame-side end member 111, which is provided at the lower part of the first mounting member 11, is brought into contact with the floor surface F on which the vertical frame 22 is installed, and the first mounting member 11 is fixed to the vertical frame 22 via fastening members such as screws SC1, as shown in Figure 3. At this time, the protruding portion 111b of the frame-side end member 111 is embedded in the mounting groove portion 222 and fixed, as shown in Figure 7A.
[0037] Next, the frame-side end member 111, which is provided on the upper part of the first mounting member 11, is similarly fixed to the vertical frame 22 via the screw SC1. This configuration eliminates the need for detailed positioning work when attaching the first mounting member 11 to the vertical frame 22, thereby improving the workability of the gap-filling material 1. Since the first mounting member 11 is fixed by simply bringing it into contact with the floor surface F, no advanced skills are required, and the first mounting member 11 can be easily attached to the vertical frame 22 in a short amount of time.
[0038] Next, the door-side end member 120 of the second mounting member 12 is fixed to the door 4. As shown in Figure 6, the lower end surface of the door-side end member 120, which is provided at the bottom of the second mounting member 12, is aligned with the bottom end of the door 4, and the extension portion 122b, which extends from the extension member 122 of the door-side end member 120 to the end of the door 4, is fixed to the end of the door 4 with a fastening member such as a screw SC3, thereby attaching the second mounting member 12 to the door 4. Similarly, the door-side end member 120, which is provided at the top of the second mounting member 12, can also be fixed to the end of the door 4 via a screw SC3, thereby attaching the gap-filling material 1 to the joinery 10.
[0039] As described above, the installation method for the gap-filling material 1 allows for quick and easy attachment of the gap-filling material 1 to the door / window 10. Furthermore, when the gap-filling material 1 is no longer needed, it can be easily removed from the door / window 10 simply by removing the screws SC1 and SC3 used for fixing. At that time, the door / window 10 can be returned to its state before the gap-filling material 1 was attached simply by fitting a portion of the previously stored vertical door stop 32 into the mounting groove 222 exposed on the visible surface of the vertical frame 22.
[0040] This disclosure is not limited to the embodiments described above and may be modified as appropriate.
[0041] For example, the joinery 10 is installed inside the room, but the joinery of this disclosure is not limited to this. Even if the joinery is installed on the exterior side, if a mounting groove for a door stop is formed in the vertical frame and a door stop is detachably provided in the mounting groove, the gap-filling material 1 can be attached to it.
[0042] Furthermore, although the cover material 13 in this embodiment is a single-width surface material without folds, the cover material of this disclosure is not limited to this. For example, an accordion-shaped cover material having multiple folds may be used.
