Description

[Technical Field]

[0001] The present invention relates to a door handle, and more particularly to a long rod-shaped door handle that is attached to a door such as a hinged door of a building. [Background technology]

[0002] Patent Document 1 describes a long rod-shaped door handle that can be attached to a swinging door or other door of a building, and that includes a round rod-shaped handle body and a pair of leg members. The handle body is arranged vertically, and the pair of leg members secure the handle body to the door at two points, near the upper and lower ends of the handle body.

[0003] In Patent Document 1, door handles are installed on both sides of the door, and a pair of leg members of the door handle installed on one side of the door are connected to a pair of leg members of the door handle installed on the opposite side of the door by a single bolt. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-261104 Summary of the Invention [Problem to be solved by the invention]

[0005] For example, in the case of a door handle to be attached to a hotel front door, a long handle body of 2 to 3 meters may be used as a round rod-shaped handle body to improve design and create a sense of luxury. When using such a long handle body for a door handle, it is preferable to make the handle body hollow cylindrical to prevent an increase in weight.

[0006] However, if the long handle body is made hollow and supported on the door only at the top and bottom edges, but not at the center, bending of the door handle can become a problem when the door is opened and closed. The human hand has excellent sensitivity to subtle deformations and displacements, so if the door handle deforms or bends when opening or closing the door, it can feel strange and reduce the feel of the door handle. Furthermore, if the door handle bends noticeably, the user's fingers may collide with the door when pushing it open, potentially resulting in injury. Furthermore, if the door handle bends when the door is repeatedly opened and closed, the handle body will repeatedly deform, potentially causing loosening of the bolts and screws that attach the handle body to the door.

[0007] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a door handle that can reduce bending during operation and improve the operating feel when the handle body is long and supported on the door only by the upper and lower ends. [Means for solving the problem]

[0008] The door handle disclosed herein includes a cylindrical handle body (10), a pair of cover bodies (20), and a pair of leg members (30). The handle body (10) is open at both ends and has a plurality of first shaft insertion holes (11) at a pair of first end portions (10b) at both ends.

Fig. 5(c) is a cross-sectional view taken along the line FF in Fig. 5(a).

[0016] As shown in Figure 1, the door handle of this embodiment is attached to a door such as a swing door of a building, and two sets of door handles attached to both sides of the door each include a handle main body 10, a pair of cover bodies 20, and a pair of leg members 30.

[0017] 2, in this embodiment, the handle body 10 is cylindrical, made of steel, has a total length of approximately 1600 to 3100 mm, a tube wall thickness of approximately 1.0 to 2.0 mm, is open at both ends, and has a pair of first ends 10b at both ends with a plurality of first shaft insertion holes 11. A plurality of shaft-shaped first fastening members 34 or a plurality of shaft-shaped second fastening members 35 is inserted into the plurality of first shaft insertion holes 11.

[0018] The door to which the door handle of the embodiment is attached is formed, for example, by a metal frame surrounding a large rectangular glass plate, and the handle body 10 is supported by the metal frame at the upper and lower ends of the door and attached to the door.

[0019] As shown in FIG. 3, in this embodiment, the pair of cover bodies 20 are cylindrical and made of a metal material such as an aluminum alloy, each having a plurality of first engaged portions 21 which are screw holes, and are inserted into both end openings 10a of the handle body 10 shown in FIG.

[0020] The multiple first engaged portions 21 are formed on the pair of cover bodies 20 so as to be aligned in the longitudinal direction of the handle body 10, and are engaged with the multiple first fastening members 34 or the multiple second fastening members 35 via the multiple first shaft insertion holes 11. Therefore, the multiple first insertion holes 11 of the handle body 10 are formed at positions that match the multiple first engaged portions 21 of the pair of cover bodies 20.

[0021] In the embodiment, the pair of cover bodies 20 each have two first engaged portions 21 as the plurality of first engaged portions 21. When the plurality of first engaged portions 21 are two first engaged portions 21, the pitch at which the two first engaged portions 21 are formed is preferably 25 to 55 mm, more preferably 30 to 50 mm, and even more preferably 35 to 45 mm.

[0022] As shown in FIG. 1, the pair of leg members 30 are connected to a pair of first end portions 10b of the handle body 10 by a plurality of first fastening members 34 or a plurality of second fastening members 35, thereby fixing the handle body 10 to the door.

[0023] As shown in FIG. 4, in this embodiment, the pair of leg members 30 includes a rectangular tubular leg body 31 and a ceiling panel 32. The leg body 31 abuts against the handle body 10 at one axial end (the upper end in FIG. 4(b)). The ceiling panel 32 has multiple third shaft insertion holes 32a, is attached to the leg body 31 so as to close the opening at one axial end of the leg body 31, and abuts against the handle body 10. Multiple first fastening members 34 or multiple second fastening members 35 are inserted into the multiple third shaft insertion holes 32a, and the heads of the multiple first fastening members 34 or multiple second fastening members 35 engage with the ceiling panel 32.

[0024] Furthermore, a pair of leg members 30 used, for example, for an interior door handle are formed with fourth shaft insertion holes 31a, and a leg connecting member 33 shown in Fig. 5 is attached to the pair of leg members 30. The leg connecting member 33 has a fifth shaft insertion hole 33a through which a third fastening member 36 is inserted. A fourth fastening member 37 shown in Fig. 1 is inserted into the fourth shaft insertion hole 31a so as to fix the leg connecting member 33 to each of the pair of leg members 30.

[0025] The third fastening member 36 connects the pair of leg members 30 of the door handle attached to both sides of the door. The leg connecting member 33 engages the head of the third fastening member 36 with the pair of leg members 30. The threaded portion of the third fastening member 36 is screwed into a screw hole formed in the head of the second fastening member 35, connecting the pair of leg members 30 of the door handle attached to both sides of the door.

[0026] The leg connecting member 33 also has a plurality of screw holes 33b that are perpendicular to the fifth shaft insertion hole 33a. Fourth fastening members 37 are screwed into the plurality of screw holes 33b through the fourth shaft insertion hole 31a of the leg body 31, fixing the leg connecting member 33 to the pair of leg members 30 and preventing the rotation of the third fastening member 36 so that it does not loosen.

[0027] As described above with reference to Figures 1 to 5, according to the door handle of the embodiment, the pair of cover bodies 20 are long (e.g., 70 to 80 mm) in the axial direction (longitudinal direction of the handle body 10) to a degree that allows a plurality of first engaged portions 21 to be formed side by side, and the pair of cover bodies 20 having such a certain length are inserted into both end openings 10a of the handle body 10, and a plurality of first fastening members 34 or a plurality of second fastening members 35 are engaged with the plurality of first engaged portions 21, and are connected to the pair of first end portions 10b of the handle body 10 together with the pair of leg members 30.

[0028] Therefore, the handle body 10 is fixed to the door with the pair of first end portions 10b, which are both ends, sandwiched from the inside and outside by the pair of cover bodies 20 of a certain length and the pair of leg members 30. As a result, the pair of first end portions 10b are supported at two or more points by the pair of cover bodies 20 and the pair of leg members 30, which suppresses deformation due to the seesaw movement that tends to occur in the case of single-point support, and can suppress bending over the entire length of the handle body 10. When the handle body 10 is long and supported by the door only at the upper and lower ends, bending during operation can be suppressed, improving the operating feel.

[0029] Next, another embodiment of the present invention will be described with reference to Fig. 6 to Fig. 8. Fig. 6(a) is a vertical cross-sectional view showing a door handle according to another embodiment of the present invention. Fig. 6(b) is a cross-sectional view taken along arrow GG in Fig. 6(a). Fig. 7(a) is a front view showing a lid according to another embodiment. Fig. 7(b) is a cross-sectional view taken along arrow HH in Fig. 7(a). Fig. 7(c) is a side view showing a lid according to another embodiment. Fig. 8(a) is a front view showing a reinforcing tubular member according to another embodiment. Fig. 8(b) is a cross-sectional view taken along arrow II in Fig. 8(a).

[0030] 6 and 7, in the door handle of this embodiment, a pair of cover bodies 20A have cylindrical abutment portions 22 and columnar protrusions 23, and multiple engaged portions 21 are formed on the abutment portions 22. The abutment portions 22 have substantially the same shape as the cover body 20 of the above embodiment, and abut against the inner wall of the handle body 10. In this embodiment, the protrusions 23 are cylindrical with a smaller diameter than the abutment portions 22, and protrude from one end face 22a of the abutment portions 22 toward the center of the handle body 10 in the longitudinal direction.

[0031] 6 and 8, the door handle of this embodiment further includes a reinforcing cylindrical body 40. The reinforcing cylindrical body 40 is open at both ends and has a cross-sectional shape that is inscribed in the inner wall of the handle body 10. The protrusions 23 of the pair of lid bodies 20A are inserted into the openings 40a at both ends of the reinforcing cylindrical body 40. In this embodiment, the cross-sectional shape of the reinforcing cylindrical body 40 is polygonal, more specifically, quadrilateral (square).

[0032] 8, the reinforcing cylinder 40 has a plurality of second shaft insertion holes 41 at both ends, and each of the protruding portions 23 of the pair of lid bodies 20 has a plurality of second engaged portions 23a. Fifth fastening members 38, which serve as other fastening members, are inserted into the second shaft insertion holes 41. The second shaft insertion holes 41 are formed at positions that coincide with the second engaged portions 23a.

[0033] The multiple second engaged portions 23a are formed on each protruding portion 23 so as to be aligned in the longitudinal direction of the handle body 10, and are engaged with the fifth fastening member 38 via the multiple second shaft insertion holes 41. In addition, as shown in FIG. 1, a sound-deadening material such as gummed tape 42 can be wrapped around the reinforcing cylinder 40 to reduce noise generated by collision between the reinforcing cylinder 40 and the inner wall of the handle body 10.

[0034] As described above with reference to Figures 6 to 8, according to the door handle of the embodiment, the reinforcing cylinder 40 is disposed in the hollow portion of the handle body 10 so as to be inscribed within the inner wall of the handle body 10, and the protrusions 23 of the pair of lid bodies 20 are inserted into the openings 40a at both ends of the reinforcing cylinder 40. Therefore, it is possible to suppress deflection of the entire length of the handle body 10, particularly in the portion between the pair of lid bodies 20, and when the handle body 10 is long and supported by the door only at the upper and lower ends, it is possible to more effectively suppress deflection during operation and improve the operating feel.

[0035] 6 to 8, in the door handle of the embodiment, the cross-sectional shape of the reinforcing cylindrical body 40 is polygonal, and in this embodiment, rectangular, so that even when a pan head screw is used as the fifth fastening member 38, as shown in Fig. 6(b), it is easy to ensure a space large enough to accommodate the head of the screw between the inner wall of the handle body 10 and the reinforcing cylindrical body 40. Therefore, the pair of lid bodies 20 and the reinforcing cylindrical body 40 can be connected more firmly than when a countersunk head screw is used as the fifth fastening member 38, and when the handle body 10 is long and supported by the door only at its upper and lower ends, deflection during operation can be more effectively suppressed, improving the operating feel.

[0036] Furthermore, as explained with reference to Figures 6 to 8, according to the door handle of the embodiment, each protrusion 23 of the pair of cover bodies 20 has a plurality of second engaged portions 23a formed in a line in the longitudinal direction of the handle body 10, and the reinforcing cylinder 40 is connected to the pair of cover bodies 20 by a plurality of fifth fastening members 38 that engage with the plurality of second engaged portions 23a.

[0037] Therefore, the reinforcing cylinder 40 itself is supported by each cover body 20 at two or more points, which suppresses deformation due to the seesaw movement that tends to occur when supported at one point, and also suppresses bending of the reinforcing cylinder 40 itself.When the handle body 10 is long and is supported by the door at only the upper and lower ends, bending during operation can be more effectively suppressed, improving the operating feel.

[0038] The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 8). However, the present invention is not limited to the above embodiments, and can be embodied in various forms without departing from the spirit of the present invention (for example, (1) to (2) below).

[0039] (1) In the above embodiment, a square pipe was used as the reinforcing cylinder 40. However, the reinforcing cylinder 40 only needs to be inscribed within the inner wall of the handle body 10, and a round pipe can also be used as the reinforcing cylinder 40.

[0040] (1) In the above embodiment, the protrusions 23 of the pair of lid bodies 20A were cylindrical, but the protrusions 23 may be polygonal pillars such as square pillars as long as they fit into both end openings 40a of the reinforcing cylinder 40. [Explanation of symbols]
