[0010] (Embodiment) An example of an embodiment of the present invention will be described with reference to the drawings. As shown in Figures 1(a) and 1(b), the pull tab 30 of the present invention is installed in a notch 41 formed at the butt end of a sliding door 40.

[0011] As an example, the pull tab 30 shown in Figures 1(a)(b) and 2 comprises a first member 10 and a second member 20 that are installed in a cutout portion 41 of a sliding door 40. For the sake of convenience, Figures 1(a)(b) show only a portion of the sliding door 40 (the area around the cutout portion 41), and do not show the entire sliding door 40.

[0012] The first member 10 is a member that is placed on the butt end side of the cutout portion 41. As an example, the first member 10 shown in Figures 2 and 3(a) and (b) has a first handle portion 11 in the shape of a vertical rectangle that is used to place a finger when closing the sliding door 40, and a partition portion 12 that protrudes from the back side of the first handle portion 11.

[0013] First insertion holes 11a are provided at positions near the upper and lower longitudinal ends of the first handhold portion 11, penetrating from the first handhold portion 11 to the end face of the partition portion 12 on the second member 20 side. The first insertion holes 11a are holes for inserting fasteners 14 used to fix the first member 10 and the second member 20 to the cutout surface 41a.

[0014] In this embodiment, a cap 13 that can be fitted into the first insertion hole 11a is provided, and after the first member 10 and the second member 20 are fixed with a fixing device 14, the first insertion hole 11a can be closed with the cap 13. This cap 13 is a member for hiding the fixing device 14.

[0015] The cap 13 in this embodiment has a closed surface 13a and two locking pieces 13b protruding from the back side of the closed surface 13a. An insertion groove 13c is formed in the closed surface 13a, and various jigs such as a flathead screwdriver or a fingernail can be inserted into this insertion groove 13c to remove the cap 13. The cap 13 may have a different configuration, and can be omitted if not needed.

[0016] The partition 12 includes a thin plate portion 12a, and upper and lower thick portions 12b and 12c, which are thicker than the thin plate portion 12a and are provided above and below the thin plate portion 12a. Recessed portions 12d are provided on the top surface of the upper thick portion 12b and on the bottom surface of the lower thick portion 12c, and a drop-out prevention portion 21j, which will be described later, is accommodated in the recessed portions 12d.

[0017] A retaining portion 12e against which the fall-off prevention portion 21j abuts is provided on the outer side of each recessed portion 12d in the thickness direction of the sliding door 40 (hereinafter referred to as the "sliding door thickness direction") In this embodiment, the peripheral wall constituting the recessed portion 12d is used as the retaining portion 12e, but the retaining portion 12e can also be provided separately from the peripheral wall.

[0018] An abutment portion 12f that abuts against the notched surface 41a is provided on the forward side in the protruding direction of the partition portion 12. In this embodiment, the abutment portion 12f is a long, narrow protrusion that extends along the longitudinal direction of the partition portion 12, and its tip end surface (flat surface) is in surface contact with the notched surface 41a (FIG. 1(b)) (FIGS. 6(a) and 6(b)).

[0019] In this way, when the first member 10 and the second member 20 are fixed to the cutout surface 41a, the abutment portion 12f of the first member 10 abuts against the cutout surface 41a, thereby preventing misalignment or deformation of both bases 21 (described later) when the fixing device 14 is tightened.

[0020] The second member 20 is a member that is disposed on the cutout surface 41a side of the cutout portion 40. As an example, the second member 20 shown in Figures 2 and 4(a) and (b) has two bases 21. Both bases 21 have the same structure and can be used upside down as shown in Figure 2.

[0021] The base 21 in this embodiment is a U-shaped member having a second handhold portion 21a on which the fingers are hooked when opening the sliding door 40, a first protruding portion 21b protruding from the upper end side of the second handhold portion 21a toward the first member 10, and a second protruding portion 21c protruding from the lower end side of the second handhold portion 21a toward the first member 10.

[0022] The surfaces of the first protruding portion 21b and the second protruding portion 21c facing the first member 10 are provided with storage cutout portions 21d that are cut out in a rectangular shape in plan view. The storage cutout portions 21d are portions that become recessed portions that are horizontally rectangular in plan view when the two bases 21 are butted together, and are portions into which the first member 10 fits when the first member 10 and the second member 20 are placed in the cutout portions 41.

[0023] Of the second handhold portions 21a of both bases 21, one semicircular protruding mating portion (hereinafter referred to as "mating protrusion") 21e and one semicircular recessed mating portion (hereinafter referred to as "mating recess") 21f are provided at a position facing the other second handhold portion 21a. The mating protrusions 21e and mating recesses 21f are provided at intervals in the longitudinal direction of the second handhold portion 21a. Two or more mating protrusions 21e and mating recesses 21f may be provided.

[0024] The mating protrusion 21e and mating recess 21f in this embodiment are not configured such that the overlapping portions are stacked in the thickness direction as in the pull tab described in Patent Document 1, but rather, it is sufficient to simply butt the mating protrusion 21e of one base 21 against the mating recess 21f of the other base 21 on the same plane, making it easy to fit the bases 21 together.

[0025] Each fitting protrusion 21e is provided with a second insertion hole 21g through which the fixing device 14 can be inserted. The second insertion hole 21g is provided at a position that communicates with the first insertion hole 11a when the first member 10 and the second member 20 are installed in the cutout portion 41.

[0026] In this embodiment, the second insertion hole 21g is an elongated hole, so that even when the base 21 is separated in the thickness direction of the sliding door, the first insertion hole 11a and the second insertion hole 21g are connected to each other and the fixing device 14 can be passed through.

[0027] A vertically elongated notch 21h is provided between the fitting protrusion 21e and the fitting recess 21f of each of the bases 21. This vertically elongated notch 21h is a portion that becomes a vertically rectangular through-hole when the two bases 21 are butted together, and is a portion through which the abutting portion 12f of the first member 10 passes when the first member 10 and the second member 20 are placed in the notch 41.

[0028] A flange 21i is provided on the surface of each base 21 opposite to the surface on which the mating protrusion 21e and mating recess 21f are formed. The flange 21i is a part that overlaps with the surface of the sliding door 40 when attached to the cutout 41. The flange 21i hides the gap between the sliding door 40 and the handle 30, preventing the user's fingernail from getting caught in the gap.

[0029] A drop-out prevention portion 21j is provided on the inner surface (the surface facing each other) of the first protruding portion 21b and the second protruding portion 21c of each base 21. As shown in Figures 4(a) and 4(b), the drop-out prevention portion 21j in this embodiment is an elongated protrusion, and is provided in a direction parallel to the retaining portion 12e of the first member 10.

[0030] In this embodiment, the case where the fall-off prevention portion 21j is a single protrusion is shown as an example, but the fall-off prevention portion 21j can also be configured with two or more protrusions. Also, the fall-off prevention portion 21j can have a shape other than a protrusion. Note that the fall-off prevention portion 21j may be provided as needed, and can be omitted if not required. When the fall-off prevention portion 21j is omitted, the retaining portion 12e can also be omitted.

[0031] 5(a) to 5(c), locking hooks 21k are provided on the surfaces of the first protruding portion 21b and the second protruding portion 21c that face the other base 21. Each locking hook 21k is configured so that the locking hook 21k provided on one base 21 locks with the locking hook 21k provided on the other base 21.

[0032] Specifically, the bases 21 have abutment surfaces 21m that butt against each other when they move apart in the thickness direction of the sliding door, and the abutment surfaces 21m butt against each other, locking the bases 21 together. The locking hook portion 21k may be provided as needed, and can be omitted if not required.

[0033] 7(a) to 7(c), in this embodiment, both bases 21 are movable in the thickness direction of the sliding door. By making it possible to move both bases 21 in the thickness direction of the sliding door, the dimension of the sliding door in the thickness direction can be adjusted.

[0034] The sliding door 40 may be made of plywood made up of multiple overlapping boards, in which case the thickness of the overlapping boards will cause variations in the thickness of the sliding door 40. In this embodiment, the thickness of the sliding door can be adjusted by moving the two bases 21 in the thickness direction of the sliding door, so it can be attached to sliding doors 40 of various thicknesses.

[0035] In addition, in this embodiment, since the fixing device 14 is inserted into each of the two bases 21, even if both bases 21 are detached from the sliding door 40, the bases 21 will not fall off from the sliding door 40.

[0036] The pull tab 30 of the present invention can be made of various materials such as zinc, aluminum, brass, stainless steel, and resin, and can also be made of a combination of these materials.

[0037] (Other embodiments) Although not described in the above embodiment, non-slip protrusions (not shown) may be provided in the upper and lower regions of the partition 12 on the back surface side of the first handhold portion 11 and in the regions of the upper thick portion 12b and the lower thick portion 12c that abut against the second handhold portion 21a. The non-slip protrusions may also be provided in the portion of the abutting portion 12f that abuts against the notched surface 41a.

[0038] In the above embodiment, an example is shown in which two bases 21 of the same structure are used upside down, but bases of different structures may be used as the two bases 21. The second member 20 may also be composed of one base 21 or three or more bases 21.

[0039] In the above embodiment, the case where the caps 13 are individually attached to the first insertion holes 11a is taken as an example, but it is also possible to make it possible to close the first insertion holes 11a with one cap 13.

[0040] 8, the blocking surface 13a may be formed in a vertically elongated shape capable of blocking the upper and lower first insertion holes 11a, with two locking pieces 13b projecting from the upper and lower sides of the back surface thereof. In this case, a recess 11b having a length spanning the upper and lower first insertion holes 11a may be provided on the front surface side of the first grip portion 11, and the blocking surface 13a may be fitted into the recess 11b.

[0041] In addition, although not shown, the cap 13 may be in the form of a vertically long flat plate (without the locking piece 13b in FIG. 8) that can close the upper and lower first insertion holes 11a. In this case, the recess 11b on the front surface side of the first grip portion 11 may be formed as a through groove that penetrates in the longitudinal direction, and the flat cap 13 may be slidably inserted into the through groove.

[0042] In this way, by using a cap 13 with a vertically elongated blocking surface 13a that can block the upper and lower first insertion holes 11a or a flat cap 13, not only is workability improved, but the design is also improved, resulting in a better appearance when installed on the sliding door 40.

[0043] The configuration described in the above embodiment is merely an example, and the pull tab 30 of the present invention is not limited to the configuration of the above embodiment. The pull tab 30 of the present invention can be modified, replaced, or omitted from the configuration within the scope that does not change the gist of the invention.

[0044] The pull tab 30 of this embodiment can be installed in the notch 41 as follows. (1) As shown in FIG. 5(a), two bases 21 are butted together so that the mating convex portion 21e of each base is fitted into the mating concave portion 21f of the other base. (2) The two bases 21 that are butted together are arranged on the cutout surface 41 a side of the cutout portion 41 , and both bases 12 are brought into contact with the inner peripheral surface of the cutout portion 41 . (3) The first member 10 is placed in the recess formed between the first protruding portion 21b, the second handhold portion 21a, and the second protruding portion 21c of both bases 21. At this time, as shown in FIG. 6(b), the abutting portion 12f of the first member 10 is brought into abutment with the cutout surface 41a. (4) The fasteners 14 are inserted into both the first insertion holes 11a and both the second insertion holes 21g from the outside of the first member 10 and screwed into the notched surface 41a, thereby fixing the first member 10 and the second member 20 to the notched surface 41a. (5) After the fixing by the fixing device 14 is completed, the caps 13 are attached to both first insertion holes 11a, and the attachment of the pull tab 30 is completed. [Industrial Applicability]

[0045] The pull handle 30 of the present invention can be attached to various sliding doors 40 such as single sliding doors and double sliding doors, and is particularly suitable for use as a pull handle 30 attached to a sliding door housed in a door pocket. [Explanation of symbols]
