Description

[Technical field]

[0001] The present invention relates to a pull member for a sliding door, and more particularly to a pull member that is attached to a notch formed by cutting out an end portion of a sliding door. [Background technology]

[0002] Conventionally, handle members for sliding doors include those that are attached by hollowing out a portion near the end of the sliding door, and those that are attached to a notch formed by cutting out the end of the sliding door (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2013-23924 A [Patent Document 2] JP 2019-116768 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the pull member disclosed in Patent Document 1, which is attached to a notch formed by cutting out the end portion of a sliding door, the end portion of the sliding door is partially cut out in the thickness direction from both sides of the sliding door so that the center part of the sliding door in the thickness direction remains, and the pull member is attached to the notch. This has the advantage that a common pull member can be used regardless of the thickness dimension of the sliding door, but it has the problem that it requires effort and skill to form a cutout in the sliding door to attach the pull member.

[0005] On the other hand, the pull handle member disclosed in Patent Document 2 comprises first and second frame members divided in the thickness direction of the sliding door, which are open on the buttock side and form a pull handle space that penetrates in the thickness direction of the sliding door, and a partition member equipped with a partition panel portion that divides the pull handle space at a predetermined position in the thickness direction of the sliding door, and an buttock panel portion that closes the buttock side of the pull handle space formed integrally with the buttock side of the partition panel portion. This solves the problems with the pull handle member disclosed in Patent Document 1, and the cutout portion of the sliding door for attaching the pull handle member can be easily formed by giving the cutout portion a simple shape.

[0006] However, the pull member disclosed in Patent Document 2 has a problem in that the screws and screw holes for fixing the first frame member and the second frame member to the sliding door are exposed in conspicuous locations.

[0007] In view of the problems with the pull member disclosed in Patent Document 2, which is attached to a notch formed by cutting out the end wood of the conventional sliding door, the present invention aims to provide a pull member for a sliding door which enables the pull member to be firmly fixed to the sliding door without rattling, while preventing the screws and screw holes for fixing the pull member to the sliding door from being exposed in conspicuous places. [Means for solving the problem]

[0008] In order to achieve the above object, the sliding door pull member of the present invention is attached to a notch formed by cutting out the edge of a sliding door, and comprises a pull body consisting of a front panel, a partition panel and a rear panel, a lower member having a groove into which the lower edge of the pull body fits and a rising piece located on the rear side of the rear panel, and an upper member formed by dividing the pull body into a groove into which the upper edge of the pull body fits and which sandwiches the upper edge of the partition panel from both sides. The screw hole is formed in the threaded piece and the upper member.

[0009] In this case, the pull body may be made of metal, and the lower and upper members may be made of synthetic resin.

[0010] Also, a screw hole may be formed in the upper end of the boundary between the partition panel and the rear panel.

[0011] Also, a protrusion may be formed on the upper surface of the upper member for abutting against the lower surface of the notch of the sliding door to determine the fixed position of the upper member in the height direction.

[0012] The protrusion may extend in the width direction of the upper member and have a triangular cross-sectional shape. Effect of the Invention

[0013] According to the sliding door pull member of the present invention, the pull member is attached to a notch formed by cutting out the edge of the sliding door, and comprises a pull body consisting of a front panel, a partition panel and a rear panel, a lower member having a groove into which the lower edge of the pull body fits and a raised piece located on the rear side of the rear panel, and an upper member formed as a separate piece having a groove into which the upper edge of the pull body fits and sandwiching the upper edge of the partition panel from both sides, with screw holes formed in the raised piece of the lower member and the upper member, so that the screws and screw holes for fixing the pull member to the sliding door are not exposed in conspicuous places, and the pull member can be firmly fixed to the sliding door without rattling.

[0014] Furthermore, by making the pull body out of metal and the lower and upper components out of synthetic resin, it is possible to improve the fit between the components while enhancing the design, and eliminate rattling between the components of the pull member.

[0015] Furthermore, by forming a screw hole in the upper end of the boundary between the partition panel portion and the rear panel portion, the handle member can be more securely fixed to the sliding door.

[0016] Furthermore, by forming a protrusion on the upper surface of the upper member to abut against the underside of the cutout in the sliding door and determine the fixed position of the upper member in the height direction, it is possible to prevent a gap from occurring between the upper member and the handle body even if the dimensional accuracy of the cutout formed by cutting out the edge of the sliding door is poor.

[0017] By making the protrusion extend in the width direction of the upper member and have a triangular cross-sectional shape, the upper member can be attached smoothly and the height of the protrusion can be easily adjusted. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a sliding door pull member of the present invention will be described with reference to the drawings.

[0020] 1 and 2 show one embodiment of a pull member for a sliding door according to the present invention. The pull member of this sliding door is attached to a notch formed by cutting out the edge of the sliding door D, and comprises a pull body 1 consisting of a front panel portion 11, a partition panel portion 12 and a rear panel portion 13, a lower member 2 equipped with a groove 21 into which the lower edge of the pull body 1 fits and a raised piece 22 located on the back side of the rear panel portion 13, and upper members 3A, 3B formed as separate parts having grooves 31a, 31b into which the upper edge of the pull body 1 fits and which clamp the upper edge of the partition panel portion 12 from both sides, with screw holes 23, 32a, 32b formed in the raised piece 22 of the lower member 2 and the upper members 3A, 3B.

[0021] The pull handle main body 1, lower component 2 and upper components 3A, 3B can be made of die-cast metal (including alloys) such as aluminum, zinc, magnesium, etc., or made of synthetic resin. In particular, by making the pull handle main body 1 out of die-cast metal and the lower component 2 and upper components 3A, 3B out of synthetic resin, it is possible to improve the fit between the components while enhancing the design, and eliminate any rattling between the components of the pull handle.

[0022] The width of the front plate portion 11 is formed smaller than the width of the rear plate portion 13. As a result, even in the case of the sliding door D in a form in which the entire sliding door D is housed in the door pocket, the sliding door D housed in the door pocket can be pulled out by pinching the front panel portion 11.

[0023] In this embodiment, the partition panel portion 12 is located at the center of the thickness of the sliding door D, but it can be located offset from the center of the thickness of the sliding door D depending on the manner in which the sliding door D is used.

[0024] The handle member of this sliding door is configured by forming screw holes 23, 32a, 32b in the rising piece 22 of the lower member 2 and the upper members 3A, 3B, so that the screws 4 and screw holes 23, 32a, 32b for fixing the handle member to the sliding door D are not exposed in a conspicuous location (out of sight as shown in Figure 1(d)), and the handle member can be firmly fixed to the sliding door D without any rattling. Here, by forming the cross-sectional shape of the groove into which the upper edge (and / or lower edge) of the handle body 1 fits, for example, grooves 31a, 31b into which the upper edge of the front panel portion 11 fits, into a trapezoid (a shape in which the groove width gradually narrows toward the back), the handle member can be more firmly fixed to the sliding door D without rattling.

[0025] 3 to 6 show a first modified embodiment of a pull member for a sliding door according to the present invention. This sliding door pull member is configured by forming a screw hole 14 at the upper end of the boundary between the partition panel portion 12 and the rear panel portion 13 of the sliding door pull member shown in Figs. In this case, the screw 4 may be screwed directly into the screw hole 14, but in order to ensure that the seating surface of the screw 4 is stably seated, a screw abutment portion 33 may be provided on the upper member 3A, and the screw 4 may be screwed into the screw hole 14 via the screw abutment portion 33, or the screw abutment portion 33 may be constructed as an independent separate member. This allows the handle member to be fixed more firmly to the sliding door D.

[0026] Other configurations and functions and effects of the first modified embodiment are similar to those of the sliding door pull member shown in Figs.

[0027] Incidentally, in the embodiment of the sliding door handle member described above, when the upper members 3A, 3B are fixed with the screws 4, an upward force acts on the upper members 3A, 3B, causing them to be lifted up. Therefore, as shown in Figure 7, if the dimensional accuracy of the notch K formed by cutting out the end portion of the sliding door D is poor, specifically, if the height dimension H of the notch K is formed larger than the design dimension, a gap G will be generated between the upper members 3A, 3B and the handle body 1.

[0028] FIG. 8 shows a second modified embodiment of a sliding door pull member of the present invention which is designed to address this issue. The handle member of this sliding door is formed with a protrusion 34 on the upper surface of the upper members 3A, 3B to abut against the lower surface of the cutout portion K of the sliding door D and determine the fixed position of the upper members 3A, 3B in the height direction.

[0029] Preferably, a plurality of protrusions 34 (three each in this embodiment) extend in the width direction of the upper members 3A, 3B and have a triangular cross-sectional shape. Here, the protrusions 34 have their ends on the widthwise center side of the upper members 3A, 3B cut obliquely so that their height gradually decreases, making it easier for the upper members 3A, 3B to be inserted. This allows the upper components 3A, 3B to be smoothly attached (the protrusions 34 are pressed into the sliding door D from the side thereof so that they bite into the sliding door D), and also makes it easy to adjust the height of the protrusions 34 (if the height dimension H of the cutout K is formed according to the design dimension and no gap G occurs, for example, the protrusions 34 (all or part of them) can be cut off using a cutter or the like).

[0030] By forming the protrusions 34 on the upper surfaces of the upper members 3A, 3B, even if the dimensional accuracy of the notch K formed by cutting out the edge of the sliding door D is poor, when the upper members 3A, 3B are fixed with the screws 4, even if an upward force acts on the upper members 3A, 3B, the protrusions 34 formed on the upper surfaces of the upper members 3A, 3B abut against the underside of the notch K of the sliding door D, determining the fixed position of the upper members 3A, 3B in the height direction, and the upper members 3A, 3B are not lifted, thereby preventing the occurrence of a gap G between the upper members 3A, 3B and the handle body 1. Here, the protrusion 34 creates a gap between the underside of the cutout portion K of the sliding door D and the upper surfaces of the upper members 3A, 3B, but this gap is covered by the raised edge 35 formed on the outer periphery of the upper members 3A, 3B and is not exposed.

[0031] Other configurations and functions and effects of the second modified embodiment are similar to those of the pull member for the sliding door shown in Figs.

[0032] The above describes the sliding door handle member of the present invention based on its embodiment, but the present invention is not limited to the configuration described in the above embodiment, and the configuration can be changed as appropriate within the scope of the spirit of the present invention. [Industrial Applicability]

[0033] The sliding door handle member of the present invention can firmly fix the handle member to the sliding door without rattling, while ensuring that the screws and screw holes for fixing the handle member to the sliding door are not exposed in conspicuous locations, and therefore can be suitably used as a handle member for various sliding doors and sliding doors of various thicknesses.
