Description

[Technical Field]

[0001] The present invention relates to a sliding door pull tab that is attached to a recess formed in the edge of a sliding door to open and close the door, and in particular to a sliding door pull tab that is provided with a pull member having a finger grip on each side of the sliding door in the thickness direction. [Background technology]

[0002] Conventionally, a known sliding door pull handle of this type is described, for example, in Patent Document 1 (JP 2019-70251 A). As shown in FIG. 10, this sliding door pull handle Ha is attached to a generally rectangular recess 6 formed in an open position on the butt end surface 2 in the opening and closing direction of the sliding door 1 and having a bottom wall surface 3, an upper wall surface (not shown), and a lower wall surface (not shown). The sliding door pull handle Ha is configured to include a first pull handle member 110a provided on one side of the recess 6 in the thickness direction R of the sliding door 1 and having a finger hook portion 100 on one side for hooking a finger, and a second pull handle member 110b provided on the other side of the recess 6 in the thickness direction R of the sliding door 1 and having the same finger hook portion 100 as the first pull handle member 110a on the other side. The finger hook portion 100 is formed in a concave shape with a front hook portion 101 on the butt end surface 2 side of the recess 6, a rear hook portion 102 on the bottom wall surface 3 side of the recess 6, and a bottom portion 103. The first pull member 110a and the second pull member 110b are made of, for example, zinc die-cast.

[0003] In this conventional sliding door pull tab Ha, since there are various sliding doors 1 with different thicknesses, in order to accommodate this, attachment means 120 is provided on the opposing back surfaces of one pull tab member 110a and the other pull tab member 110b to attach one pull tab member 110a and the other pull tab member 110b to the bottom wall surface 3 of the recess 6 with a single screw B so that the distance between these pull tab members 110a and 110b in the thickness direction R of the sliding door in the recess 6 can be adjusted. A pair of attachment means 120 is provided, one above the other. This attachment means 120 is composed of an integrally molded rear protrusion 121 and a separate front protrusion 122, each of which is provided on the opposing back surfaces of the first pull-tab member 110a and the other pull-tab member 110b and has a portion shaped like a semi-circular truncated cone in cross section with a groove for receiving a screw B, and a pair of metal fittings 123, 124 with an umbrella cross section that engage with the rear protrusion 121 and the front protrusion 122, respectively, and pull the first pull-tab member 110a and the other pull-tab member 110b toward the screw B when the screw B is screwed in. The spacing between the first pull-tab member 110a and the other pull-tab member 110b can be adjusted depending on the degree to which the metal fittings are pulled, to correspond to the thickness of the sliding door. Reference numeral 125 denotes a plate-shaped cover that is provided on the front surfaces of the first pull-tab member 110a and the other pull-tab member 110b, spanning them and covering the space between the first pull-tab member 110a and the other pull-tab member 110b.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-70251 Summary of the Invention [Problem to be solved by the invention]

[0005] In this conventional sliding door pull tab Ha, the mounting means 120 is constructed with an integrally molded rear protrusion 121 and a separate front protrusion 122, as well as a pair of umbrella-shaped metal fittings 123, 124 that engage with them, making the structure complex. Furthermore, the engagement of the metal fittings 123, 124 with the rear protrusion 121 and the front protrusion 122 can become shallow, making the adjustment range relatively narrow, and when the engagement becomes shallow, the holding becomes unstable. This resulted in a problem of poor versatility. The present invention has been made in consideration of the above problems, and aims to provide a sliding door pull tab that simplifies the structure of the mounting means and allows for a relatively large adjustment range, thereby improving versatility. [Means for solving the problem]

[0006] To achieve this purpose, the sliding door pull handle of the present invention is attached to a generally rectangular recess formed open on the end face of the wood in the opening and closing direction of the sliding door, and having a bottom wall surface, an upper wall surface, and a lower wall surface, a first pull member provided on one side of the recess in the thickness direction of the sliding door and having a finger hook portion on the one side for hooking a finger thereon; and a second pull member provided on the other side of the recess in the thickness direction of the sliding door and having a finger hook portion on the other side for hooking a finger thereon, The finger hook portion is formed in a concave shape having a front hook portion on the butt end surface side of the recess, a rear hook portion on the bottom wall surface side of the recess, and a bottom surface portion, On the back surfaces of the one pull member and the other pull member facing each other, there is provided a mounting means for mounting the one pull member and the other pull member to the bottom wall surface of the recess with one screw so that the distance between the one pull member and the other pull member in the thickness direction of the sliding door can be adjusted, The one pull member and the other pull member are each configured to include a frame-shaped handle body having the front and rear hook portions, and a bottom plate attached to the back side of the handle body and constituting the bottom portion, The mounting means is configured to be provided entirely or partially on the bottom plate.

[0007] As a result, when the first pull member and the second pull member are produced, the handle body and the bottom plate are pre-formed to the required shape. For example, the handle body can be formed from a die-cast metal such as zinc, and the bottom plate can be formed from a metal plate. In this case, since the bottom plate is plate-shaped, the attachment means can be formed, for example, by bending a portion of the bottom plate, making it easy to form the attachment means. Furthermore, since all or part of the attachment means is provided on the bottom plate, it is easy to form a long portion that can be attached with screws. In other words, since the handle body and the bottom plate are produced separately for the first pull member and the second pull member, it is easy to form the attachment means, especially the attachment means formed on the bottom plate, and the structure of the attachment means can be accordingly simplified.

[0008] The first and second pull members are then completed by attaching a bottom plate to the handle body. The bottom plate can be attached by any suitable means, such as adhesive or screws.

[0009] When this sliding door handle is attached to the recess of a sliding door, one pull member is placed on one side of the recess in the thickness direction of the sliding door, and the other pull member is placed on the other side of the recess in the thickness direction of the sliding door, and the attachment means is attached to the bottom wall of the recess by screwing a screw into the bottom wall. The distance between the one pull member and the other pull member is adjusted to match the thickness of the sliding door, and the screw is screwed in at the appropriate distance. In this case, since all or part of the attachment means is provided on the bottom plate, it is easy to form a long portion that can be attached with a screw, and the adjustment range of the distance between the one pull member and the other pull member can be relatively large. As a result, it is easy to accommodate sliding doors of various thicknesses, improving versatility.

[0010] More specifically, according to the present invention, the mounting means may be configured as necessary to include a first mounting protrusion that protrudes from the back surface of the one pull tab member or the other pull tab member, abuts against the bottom wall surface of the recess, and has a first insertion hole through which the screw is inserted; and a second mounting protrusion that protrudes from the back surface of the one pull tab member or the other pull tab member on the side opposite to the side from which the first mounting protrusion is protruding, overlaps the end face of the sliding door wood edge of the first mounting protrusion, and has a second insertion hole through which the screw is inserted; At least one of the first mounting protrusion and the second mounting protrusion is provided on the bottom plate, The first insertion hole of the first mounting protrusion and / or the second insertion hole of the second mounting protrusion provided on the bottom plate are configured as elongated holes that are long in the thickness direction of the sliding door.

[0011] In this configuration, there may be one mounting means, but multiple mounting means may be provided above and below. There are six mounting modes for the first mounting protrusion and the second mounting protrusion per mounting means: (1) First mounting protrusion: Provided on the bottom plate of one of the pull members. Second mounting protrusion: Provided on the bottom plate of the other pull member. (2) First mounting protrusion: Provided on the bottom plate of the other pull member. Second mounting protrusion: Provided on the bottom plate of one of the pull members. (3) First mounting protrusion: Provided on the handle body of one of the pull members. Second mounting protrusion: Provided on the bottom plate of the other pull member. (4) First mounting protrusion: Provided on the handle body of the other pull member. Second mounting protrusion: Provided on the bottom plate of one of the pull members. (5) First mounting protrusion: Provided on the bottom plate of one of the pull members. Second mounting protrusion: Provided on the handle body of the other pull member. (6) First mounting protrusion: Provided on the bottom plate of the other pull member. Second mounting protrusion: Provided on the handle body of one of the pull members.

[0012] When a plurality of attachment means are provided above and below, the form of each attachment means can be selected from the above forms (1) to (6).

[0013] In the above embodiments (1) and (2), the first insertion hole of the first mounting protrusion and / or the second insertion hole of the second mounting protrusion are configured as elongated holes. In the above embodiments (3) to (6), the insertion holes of the mounting protrusions provided in the bottom plate are configured as elongated holes. In this case, it goes without saying that the insertion holes of the mounting protrusions not provided in the bottom plate may also be configured as similar elongated holes.

[0014] As a result, when the first and second pull members are produced, the handle body and the bottom plate are pre-formed to the required shape. For example, the handle body can be formed from a die-cast metal such as zinc, and the bottom plate can be formed from a metal plate. In this case, when providing the first or second mounting protrusion on the handle body, the handle body is frame-shaped, which makes it easier to form the first or second mounting protrusion compared to conventional methods in which the mounting means is formed on the back surface of the bottom of the concave finger hook. Furthermore, since the bottom plate is plate-shaped, the first and / or second mounting protrusions provided on the bottom plate can be formed by, for example, bending a portion of the bottom plate, making them easier to form. Furthermore, since the bottom plate is plate-shaped, the elongated holes for the mounting protrusions provided on the bottom plate are easily formed. In other words, for the first pull member and the second pull member, the handle body and the bottom plate are made separately, which makes it easier to form the attachment means and thus simplifies the structure of the attachment means. Also, since the elongated holes formed in the attachment protrusions on the bottom plate are machined into the plate material, the length of these elongated holes can be made relatively long.

[0015] The first and second pull members are then completed by attaching a bottom plate to the handle body. The bottom plate can be attached by any suitable means, such as adhesive or screws.

[0016] To attach this sliding door handle to a recess in a sliding door, first place the first handle member on one side of the recess in the thickness direction of the sliding door, and then place the second handle member on the other side of the recess in the thickness direction of the sliding door. Then, the first and second mounting protrusions of the mounting member are overlapped, and screws are inserted into the first and second insertion holes and screwed into the bottom wall of the recess to fasten them together. The first and second mounting protrusions are slid to adjust the distance between the first and second handle members to fit the thickness of the sliding door, and the screws are screwed into the appropriate distance. The elongated holes formed in the bottom plate allow for easy spacing adjustment. In particular, the elongated holes formed in the mounting protrusions on the bottom plate are machined into a plate material, allowing for a relatively long length, thereby enabling a relatively wide adjustment range for the distance between the first and second handle members. This allows for easier compatibility with sliding doors of various thicknesses, improving versatility.

[0017] And, if necessary, The mounting means is provided as a pair at the top and bottom, In the upper attachment means, the first attachment protrusion is provided on the back surface side of the handle body of either the one pull-tab member or the other pull-tab member, and the second attachment protrusion is provided on the back surface side of the bottom plate of the other of the one pull-tab member or the other pull-tab member, In the lower mounting means, the first mounting protrusion is provided on the back side of the handle body of either the one pull-handle member or the other pull-handle member, and the second mounting protrusion is provided on the back side of the bottom plate of either the one pull-handle member or the other pull-handle member.

[0018] That is, it is a configuration in which the above aspects (3) and (4) coexist. Specifically, when the upper attachment means is in the form (3), the lower attachment means is in the form (4), and when the upper attachment means is in the form (4), the lower attachment means is in the form (3).

[0019] In this configuration, the attachment means is configured so that the first attachment protrusion on the handle body and the second attachment protrusion on the bottom plate overlap above and below the first pull-hand member and the other pull-hand member, so the handle body and the bottom plate can be fastened together with screws, ensuring reliable fastening of the first pull-hand member and the other pull-hand member. Also, the first attachment protrusion is provided on the handle body and abuts against the bottom wall of the recess, providing stable support.

[0020] In this case, it is also effective to form the first pull-tab member and the second pull-tab member to the same size and shape and arrange them upside down so that their bottom plates face each other. That is, the handle body of the first pull-tab member and the handle body of the second pull-tab member are formed to the same size and shape, and the bottom plate of the first pull-tab member and the bottom plate of the second pull-tab member are formed to the same size and shape, and the bottom plate is attached to the handle body. As a result, when the first pull-tab member is rotated 180° about a vertical axis passing through the first pull-tab member and then further rotated 180° about an orthogonal axis perpendicular to the vertical axis passing through the first pull-tab member, the first pull-tab member becomes the second pull-tab member. In other words, the first pull-tab member and the second pull-tab member are rotationally symmetrical about two axes. As a result, when one pull tab member is produced, the other pull tab member is also produced; in other words, when the other pull tab member is produced, the one pull tab member is also produced, so it is only necessary to produce one type of one pull tab member or one type of other pull tab member, thereby improving manufacturing efficiency.

[0021] In this case, it is effective to form the first mounting protrusion in a block shape having an outer joint surface that joins to the bottom wall surface of the recess and an inner joint surface that joins to the second mounting protrusion, and to integrally form the second mounting protrusion by bending a part of the bottom plate so as to join to the inner joint surface of the first mounting protrusion.The outer joint surface of the block-shaped first mounting protrusion provided on the handle main body is supported on the bottom wall surface of the recess, and the plate-shaped second mounting protrusion on the bottom plate is supported on the inner joint surface of the block-shaped first mounting protrusion, so that the support between the handle main body and the bottom plate is stable, and the one pull member and the other pull member can be fixed more reliably.

[0022] Furthermore, if necessary, the handle body may be formed with a hole into which the tip of the second mounting protrusion can be inserted so as to be movable back and forth in the thickness direction of the sliding door. Because the tip of the second mounting protrusion can be inserted into the hole of the handle body, the adjustment range of the gap between the first pull tab member and the second pull tab member can be increased, making it possible to accommodate sliding doors of various thicknesses, thereby further improving versatility.

[0023] If necessary, the handle body can be made of a metal casting, the bottom plate can be made of a metal plate, and the bottom plate can be fastened to the handle body with machine screws. For example, the handle body can be made of a casting such as a die-cast product made of a metal such as zinc, and the bottom plate can be made of a metal plate such as stainless steel. This makes manufacturing easier.

[0024] Furthermore, if necessary, a plate-like cover is provided on the butt end surface of the one pull member and the other pull member on the butt end end surface side of the sliding door, straddling the one pull member and the other pull member and covering the space between the one pull member and the other pull member, The cover is made of a magnetic material; The first pull member and the second pull member each have a magnet built therein for magnetically attaching the cover.

[0025] As a result, the cover is installed across the first and second pull-tab members, blocking the gap between them and concealing the screws, first mounting protrusions, and second mounting protrusions, thereby improving the appearance quality. In this case, the cover is held in place by a magnet, making it easier to attach than when adhesive is used. In addition, the cover can be easily removed when tightening the screws, etc., making it more convenient.

[0026] In this case, it is effective to form a receiving hole in the handle body that is covered with the bottom plate and that receives the magnet, so that the magnet can be received and the handle can be held securely. [Effects of the Invention]

[0027] According to the present invention, the first pull member and the second pull member each comprise a frame-shaped handle body and a bottom plate, and all or part of the attachment means is provided on the bottom plate. Since the handle body and the bottom plate are manufactured separately, the attachment means are easier to form, thereby simplifying the structure of the attachment means. Furthermore, since all or part of the attachment means is provided on the bottom plate, it is easier to form a long portion that can be attached with screws, which allows for a relatively large adjustment range for the distance between the first pull member and the second pull member. As a result, it is easier to accommodate sliding doors of various thicknesses, improving versatility. [Brief explanation of the drawings]

[Figure 10] 1 is a cross-sectional view showing an example of a conventional sliding door handle attached to a sliding door. DETAILED DESCRIPTION OF THE INVENTION

[0029] Hereinafter, a sliding door pull tab according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Note that the same reference numerals will be used to denote the same parts as those described above. The sliding door pull tab H according to the embodiment of the present invention shown in Figures 1 to 7 is attached to a substantially rectangular recess 6 formed open on the end face 2 of the sliding door 1 in the opening and closing direction, and having a bottom wall surface 3, an upper wall surface 4, and a lower wall surface 5.

[0030] The basic configuration of the sliding door pull handle H in this embodiment consists of a first pull handle member HA, which is provided on one side of the recess 6 in the thickness direction R of the sliding door 1 and has a finger hook portion 10 on one side for hooking a finger, a second pull handle member HB, which is provided on the other side of the recess 6 in the thickness direction R of the sliding door 1 and also has a finger hook portion 10 on the other side for hooking a finger, and a plate-like cover 50, which is provided across the first pull handle member HA and the other pull handle member HB on the butt end surface 2 side of the sliding door 1 of the first pull handle member HA and the other pull handle member HB and covers the space between the first pull handle member HA and the other pull handle member HB.

[0031] The finger hook portion 10 is formed in a concave shape with a front hook portion 11 on the butt end surface 2 side of the recess 6, a rear hook portion 12 on the bottom wall surface 3 side of the recess 6, and a bottom surface portion 13. Furthermore, on the opposing back surfaces of the one pull tab member HA and the other pull tab member HB, there is provided an attachment means T for attaching the one pull tab member HA and the other pull tab member HB to the bottom wall surface 3 of the recess 6 with one screw B so that the distance between them in the thickness direction R of the sliding door 1 can be adjusted.

[0032] Specifically, the first pull member HA and the second pull member HB each include a frame-shaped handle body 20 having a front hook portion 11 and a rear hook portion 12, and a bottom plate 21 attached to the back side of the handle body 20 and constituting the bottom portion 13. In this embodiment, the handle body 20 is formed of a metal casting. The bottom plate 21 is formed of a metal plate. For example, the handle body 20 may be formed of a die-cast metal such as zinc, and the bottom plate 21 may be formed of a metal plate such as stainless steel. The bottom plate 21 is fastened to the back side of the handle body 20 with a plurality of machine screws 22. Reference numeral 23 denotes a plurality of female threads formed at required intervals on the back side of the handle body 20 into which the machine screws 22 are threaded. Reference numeral 24 denotes open screw holes formed at required intervals around the periphery of the bottom plate 21 at positions corresponding to the female threads 23, through which the machine screws 22 are inserted. Additionally, a flange 25 is integrally formed around the periphery of the surface of the handle body 20 to abut against and cover the opening edge of the recess 6.

[0033] In this embodiment, the first pull-tab member HA and the second pull-tab member HB are formed to the same size and shape and are arranged upside down so that their bottom plates 21 face each other. That is, the handle bodies 20 of the first pull-tab member HA and the second pull-tab member HB are formed to the same size and shape, and the bottom plates 21 of the first pull-tab member HA and the second pull-tab member HB are formed to the same size and shape, and the bottom plates 21 are attached to the handle bodies 20. As a result, when the first pull-tab member HA is rotated 180° about a vertical axis passing through the first pull-tab member HA and then further rotated 180° about an orthogonal axis perpendicular to the vertical axis passing through the first pull-tab member HA, the first pull-tab member HA becomes the second pull-tab member HB. In other words, the first pull-tab member HA and the second pull-tab member HB are rotationally symmetric about two axes. Therefore, when one pull tab member HA is produced, the other pull tab member HB is also produced; in other words, when the other pull tab member HB is produced, the one pull tab member HA is also produced. Therefore, both the one pull tab member HA and the other pull tab member HB can be produced by producing only one type of member, and manufacturing efficiency can be improved accordingly.

[0034] The mounting means T is configured to include a first mounting protrusion 30 that protrudes from the back surface of the one pull tab member HA or the other pull tab member HB, abuts against the bottom wall surface 3 of the recess 6, and has a first insertion hole 31 formed therein through which a screw B is inserted, and a second mounting protrusion 40 that protrudes from the back surface of the one pull tab member HA or the other pull tab member HB on the side opposite to the side from which the first mounting protrusion 30 protrudes, overlaps the first mounting protrusion 30 on the butt end surface 2 of the sliding door 1, and has a second insertion hole 41 formed therein through which a screw B is inserted. At least one of the first mounting protrusion 30 and the second mounting protrusion 40 is provided on the bottom plate 21, and the first insertion hole 31 of the first mounting protrusion 30 and / or the second insertion hole 41 of the second mounting protrusion 40 that are provided on this bottom plate 21 are configured as elongated holes that are long in the thickness direction R of the sliding door 1.

[0035] In the embodiment, a pair of attachment means T are provided, one above the other. In the upper attachment means T, the first attachment protrusion 30 is provided on the back side of the handle body 20 of either one of the first pull-tab member HA or the other pull-tab member HB (in the embodiment, the handle body 20 of the first pull-tab member), and the second attachment protrusion 40 is provided on the back side of the bottom plate 21 of the other of the first pull-tab member HA or the other pull-tab member HB (in the embodiment, the bottom plate 21 of the second pull-tab member HB). In the lower attachment means T, the first attachment protrusion 30 is provided on the back side of the handle body 20 of the other of the first pull-tab member HA or the other pull-tab member HB (in the embodiment, the handle body 20 of the second pull-tab member HB), and the second attachment protrusion 40 is provided on the back side of the bottom plate 21 of either one of the first pull-tab member HA or the other pull-tab member HB (in the embodiment, the bottom plate 21 of the first pull-tab member HA).

[0036] The first mounting protrusion 30 is integrally formed in a block shape having an outer joint surface 32 that joins with the bottom wall surface 3 of the recess 6 and an inner joint surface 33 that the second mounting protrusion 40 joins with. On the other hand, the second mounting protrusion 40 is integrally formed by bending a part of the bottom plate 21 so as to join with the inner joint surface 33 of the first mounting protrusion 30. Furthermore, the handle body 20 is formed with a hole 34 into which the tip side of the second mounting protrusion 40 can be retracted so as to be movable forward and backward in the thickness direction R of the sliding door 1.

[0037] As a result, the second insertion hole 41 of the second mounting protrusion 40 provided on the bottom plate 21 is configured as an elongated hole. In this embodiment, the first insertion hole 31 of the first mounting protrusion 30 provided on the handle body 20 is configured as an elongated hole that is slightly long in the vertical direction. Note that the first insertion hole 31 may also be an open hole and may be modified as appropriate.

[0038] The cover 50 is formed into a rectangular plate from a magnetically attracting material such as stainless steel. As shown in Figures 4 and 7(c), the first pull-tab member HA and the second pull-tab member HB each have a magnet 51 built in to magnetically attract the cover 50. The handle bodies 20 of the first pull-tab member HA and the second pull-tab member HB each have a housing hole 52 covered with the bottom plate 21 that houses the magnet 51. The ability to house the magnet 51 ensures reliable holding.

[0039] In addition, a step portion 53 is formed on the butt end surface of the one pull member HA and the other pull member HB on the butt end end face 2 side of the sliding door 1, where the cover 50 fits in and is joined to make the surface of the cover 50 and the butt end surface exposed without being covered by the cover 50 flush with each other.

[0040] Therefore, when producing the first and second pull members HA and HB of the sliding door pull H according to the embodiment, the handle body 20 and the bottom plate 21 are separately formed into the required shapes in advance. For example, the handle body 20 is integrally molded using a die-cast product or other casting made of a metal such as zinc. The bottom plate 21 is formed from a magnetic metal plate such as stainless steel. In this case, since the handle body 20 is frame-shaped, the first mounting protrusion 30 provided on the handle body 20 can be easily formed compared to the conventional method of forming the mounting handle 120 on the back side of the bottom surface 103 of the concave finger hook portion 100 (see FIG. 10 ). Furthermore, the second mounting protrusion 40 provided on the bottom plate 21 can be easily formed because it can be formed by bending a portion of the bottom plate 21. Furthermore, the second insertion hole 41 of the second mounting protrusion 40 provided on the bottom plate 21 is an elongated hole that is long in the thickness direction R of the sliding door 1, but since the bottom plate 21 is plate-shaped, its formation is easy. Also, since the elongated hole is machined into the plate-shaped second mounting protrusion 40 provided on the bottom plate 21, the length of the elongated hole can be made relatively long. That is, in the one pull member HA and the other pull member HB, the handle body 20 and the bottom plate 21 are produced separately, so it is easier to form the mounting means T, and the structure of the mounting means T can be simplified accordingly.

[0041] Then, for the one pull-tab member HA and the other pull-tab member HB, magnets 51 are accommodated in accommodation holes 52 formed in the handle body 20 (see FIG. 7(c)), and then the bottom plate 21 is attached to the back surface of the handle body 20 with machine screws 22 (see FIG. 7(b)), thereby completing the assembly. In this case, the handle bodies 20 and bottom plates 21 of the one pull-tab member HA and the other pull-tab member HB are each formed to the same size and shape, and the completed one pull-tab member HA and other pull-tab member HB are also formed to the same size and shape, so that both the one pull-tab member HA and the other pull-tab member HB can be produced by simply producing one of them, thereby improving manufacturing efficiency.

[0042] Furthermore, when the sliding door pull handle H is attached to the recess 6 of the sliding door 1, one pull handle member HA is placed on one side of the recess 6 in the thickness direction R of the sliding door 1, and the other pull handle member HB is placed on the other side of the recess 6 in the thickness direction R of the sliding door 1. In this case, the one pull handle member HA and the other pull handle member HB are formed to the same size and shape, and are configured to be arranged upside down with their bottom plates 21 facing each other, and because they are in a biaxial rotational symmetry relationship, they can be easily arranged.

[0043] Then, the first mounting protrusion 30 and the second mounting protrusion 40 of the mounting member T are overlapped, and screws B are inserted into the first insertion holes 31 and the second insertion holes 41 and screwed into the bottom wall surface 3 of the recess 6 to fasten them together. At this time, the first mounting protrusion 30 and the second mounting protrusion 40 are slid to adjust the distance between the first pull member HA and the other pull member HB to match the thickness of the sliding door 1, and the screws B are screwed in at a position where the distance is appropriate. In this case, the second insertion holes 41 of the second mounting protrusion 40 provided on the bottom plate 21 are formed as elongated holes, which allows for distance adjustment. In particular, since the elongated holes are machined into the second mounting protrusion 40 provided on the bottom plate 21, the length of the elongated holes can be made relatively long, which allows for a relatively large adjustment range for the distance between the first pull member HA and the other pull member HB. Furthermore, the handle body 20 is formed with a hole 34 into which the tip of the second mounting protrusion 40 can be recessed so as to be movable back and forth in the thickness direction R of the sliding door 1, and since the tip of the second mounting protrusion 40 can be recessed into the hole 34 of the handle body 20, the adjustment range of the gap between the one pull member HA and the other pull member HB can be increased accordingly. As a result, it can be adapted to sliding doors 1 of various thicknesses, improving versatility.

[0044] Finally, a cover 50 is attached to the step 53 provided on the first pull member HA and the second pull member HB on the butt end surface 2 side of the sliding door 1. A cover 50 with the required width is prepared to match the distance between the first pull member HA and the second pull member HB. In this case, the cover 50 is magnetically held in place by the magnet 51, making it easier to attach than when using adhesive.

[0045] When the sliding door pull handle H is attached to the recess 6 of the sliding door 1, the attachment means T is configured so that the first attachment protrusion 30 provided on the handle main body 20 and the second attachment protrusion 40 provided on the bottom plate 21 overlap each other above and below the first pull handle member HA and the other pull handle member HB, so that the handle main body 20 and the bottom plate 21 can be fastened simultaneously with screws B, thereby ensuring secure fastening of the first pull handle member HA and the other pull handle member HB. Furthermore, the outer joint surface 32 of the block-shaped first attachment protrusion 30 provided on the handle main body 20 is supported by the bottom wall surface 3 of the recess 6, and the plate-shaped second attachment protrusion 40 of the bottom plate 21 is supported by the inner joint surface 33 of the block-shaped first attachment protrusion 30, providing stable support for the handle main body 20 and the bottom plate 21, further ensuring secure fastening of the first pull handle member HA and the other pull handle member HB.

[0046] In this state, the cover 50 is provided across the first pull-tab member HA and the second pull-tab member HB, thereby concealing the screw B, the first mounting protrusion 30, and the second mounting protrusion 40, thereby improving the appearance quality. Furthermore, the cover 50 can be easily removed when retightening the screw B, etc., for added convenience.

[0047] FIG. 8 shows an example of a sliding door pull according to another embodiment of the present invention, in which the first mounting protrusion 30 and the second mounting protrusion 40 are respectively provided on the bottom plate 21 of the mounting means T of the first pull-tab member HA and the other pull-tab member HB. The first pull-tab member HA and the other pull-tab member HB are rotationally symmetric about two axes, as described above. Of these, in the first pull-tab member HA and the other pull-tab member HB shown in FIG. 8(a), only the first insertion hole 31 of the first mounting protrusion 30 is configured as a long hole extending along the thickness direction R of the sliding door. In the first pull-tab member HA and the other pull-tab member HB shown in FIG. 8(b), both the first insertion hole 31 of the first mounting protrusion 30 and the second insertion hole 41 of the second mounting protrusion 40 are configured as long holes extending along the thickness direction R of the sliding door. The same functions and effects as those described above can be achieved.

[0048] 9(a) and 9(b) show an example of a sliding door pull according to yet another embodiment of the present invention, in which the first mounting protrusion 30 is provided on the bottom plate 21 and the second mounting protrusion 40 is provided on the handle body 20 in the mounting means T of the first pull member HA and the other pull member HB. The first pull member HA and the other pull member HB are similarly biaxially rotationally symmetrical. In this example, the first insertion hole 31 of the first mounting protrusion 30 in the first pull member HA and the other pull member HB is configured as a long hole that is long in the thickness direction R of the sliding door, and the second insertion hole 41 of the second mounting protrusion 40 is configured as a long hole that is slightly longer in the vertical direction. This provides the same functions and effects as those described above.

[0049] The manner in which the first and second mounting protrusions 30 and 40 are provided on the attachment means T of the first pull-tab member HA and the second pull-tab member HB is not limited to the above-described manner and may be modified as appropriate. In the above-described embodiment, the first and second pull-tab members HA and HB are rotationally symmetric about two axes, and a pair of attachment means T is provided above and below. However, this is not necessarily limited to this, and three or more attachment means T may be provided above and below. In this case, the first and second pull-tab members HA and HB do not necessarily have to be rotationally symmetric about two axes and may be modified as appropriate. The present invention is not limited to the above-described embodiment, and those skilled in the art will readily make numerous modifications to these exemplary embodiments without substantially departing from the novel teachings and effects of the present invention, and these numerous modifications are within the scope of the present invention.
