Description

[Technical Field]

[0001] The present invention relates to a handle structure. [Background technology]

[0002] Conventionally, embedded handle structures have been provided in doors and the like. For example, the handle structure disclosed in Patent Document 1 is constructed by drilling a hole in a door made of a plate material and fitting a box-shaped handle member into the hole. The handle member needs to fit within the thickness of the plate material to which it is attached. However, if the finger hook portion of the handle member is made deeper, the entire handle member becomes thicker, making it impossible to fit within the thickness of the plate material. On the other hand, if the handle member is configured to fit within the thickness of the plate material, the finger hook portion tends to be shallow. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, each embodiment of the present invention will be described with reference to the drawings.

[0016] <Embodiment 1> 1 shows a state in which a recess 200 is provided in a plate material 100 in a hand-held structure P according to a first embodiment of the present invention. Note that Fig. 1(a) is an enlarged front view of the vicinity of the recess 200 in the plate material 100, and Fig. 1(b) is a cross-sectional view taken along the line A-A.

[0017] As shown in FIG. 1 , the plate 100 is a hollow resin structure including a core layer 120 having a plurality of cells 110 therein, and includes a sheet-like surface layer 130 and a back layer 140 bonded to both the front and back sides of the core layer 120. The plate 100 constitutes a part of a door or the like of a structure, and can be operated by a user by placing their fingers on it. Furthermore, the surface layer 130 of the plate 100 is optionally provided with fixing holes 101 around a recess 200. Note that the plate 100 is a hollow resin structure including the core layer 120 having a plurality of cells 110 therein, but is not limited thereto. As long as the plate constitutes a part of a door or the like of a structure, it may be a solid structure (i.e., a wooden or metal plate) or any other structure made of any material.

[0018] In the handle structure P of the present invention, a recess 200 is first provided at a desired location on the plate material 100. The recess 200 is formed by cutting the surface layer 130 and core layer 120 of the plate material 100 using a countersinking process or the like, resulting in a space with an opening 210, an inner surface 220, and a bottom surface 230 on the opposite side of the opening 210. The opening 210 is exposed on the surface layer 130 side. The inner surface 220 is a portion of the core layer 120 exposed by the countersinking process, and the bottom surface 230 is a portion of the core layer 120 or a portion of the back surface layer 140 exposed by the countersinking process. The corners of the recess 200 cannot be machined and are therefore countersunk by hand, resulting in a greater amount of countersinking at the corners of the recess 200 than at other portions. While the recess 200 is formed by countersinking, the method is not limited thereto and may be any method. For example, the recess 200 may be formed at the same time as 3D forming the plate material 100. Furthermore, although the recess 200 has a substantially square shape when viewed from the front, it is not limited to this and may have any shape, such as a substantially circular shape.

[0019] Next, Fig. 2 shows the space forming member 300. Fig. 2(a) is an overall perspective view of the space forming member 300, Fig. 2(b) is a front view of the space forming member 300 embedded in the recess 200 of the plate material 100, and Fig. 2(c) is a cross-sectional view taken along the line B-B.

[0020] As shown in FIG. 2(a), the space-forming member 300 has a box shape including a bottom wall 310 and side walls 320 rising from the periphery of the bottom wall 310. The opposite side of the bottom wall 310 has an opening 330. The space-forming member 300 is configured to be sized to fit inside the recess 200. The space-forming member 300 is formed by folding a sheet of resin foam material and assembling it into the shape shown in FIG. 2(a). However, the space-forming member 300 is not limited to this. The space-forming member 300 may be formed by any method using any material, such as wood or metal. Since the space-forming member 300 is assembled in an expandable manner, the entire space-forming member 300 is not a single unit, and size adjustment is easy. Although the space-forming member 300 is formed in a box shape, the space-forming member 300 is not limited to this. As described below, the space-forming member 300 may have any shape as long as it covers a portion of the exposed inner surface of the recess 200.

[0021] Then, as shown in FIG. 2(b), the space forming member 300 is inserted into the recess 200 through the opening 210 and accommodated within the recess 200. Then, the inner surface 220 of the recess 200 is covered by the side wall 320 of the space forming member 300, and the bottom surface 230 of the recess 200 is covered by the bottom wall 310. In this way, the exposed inner surface of the recess 200 is covered by the space forming member 300, preventing fingers from touching the exposed inner surface of the recess 200 and getting injured. In addition, the inner surface side of the space forming member 300 is flat, further preventing injury. In addition, the opening 330 of the space forming member 300 is exposed to the surface layer 130 side of the plate material 100. 2(c), when the space forming member 300 is housed in the recess 200, at least a portion of the side wall 320 of the space forming member 300 abuts against at least the surface layer 130, thereby preventing the space forming member 300 from rattling left and right in the recess 200. As will be described later, the space forming member 300 is pressed down by a cover member 400 and fixed in the recess 200 so as not to fall out. For this reason, the space forming member 300 is not adhered to the interior of the recess 200 with an adhesive or the like, but this is not limiting, and the space forming member 300 may be adhered and fixed to the interior of the recess 200 with an adhesive or the like. Furthermore, the side wall 320 of the space forming member 300 is inclined. Furthermore, when the cover member 400 is attached, the corners between the side wall 320 and the bottom wall 310 of the space forming member 300 are arranged so that the core layer 120 bites into the intermediate forming member 300 while compressing the core layer 120, thereby preventing rattling in the front-to-rear direction. Note that when the space forming member 300 is an injection-molded product, the corners between the side wall 320 and the bottom wall 310 of the space forming member 300 are arranged so that the core layer 120 bites into the intermediate forming member 300. Also, when the space forming member 300 is a foamed product, the space forming member 300 is arranged so that the core layer 120 bites into the intermediate forming member 300 while the cover member 400 is attached.

[0022] Next, Fig. 3 shows the cover member 400. Fig. 3(a) is an overall perspective view of the cover member 400, Fig. 3(b) is a front view of the cover member 400 placed on the recess 200, and Fig. 3(c) is a cross-sectional view taken along the line CC.

[0023] As shown in FIG. 3( a), the flat-plate-shaped cover member 400 made of metal that has not been subjected to bending processing includes a main body portion 410 and a cover member-side opening 420 in the center thereof. The front surface 411 and the back surface 412 of the main body portion 410 are flat surfaces. The opening area of the cover member-side opening 420 is smaller than the opening area of the opening 210 of the recess 200. Furthermore, the opening area of the cover member-side opening 420 is smaller than the opening area of the opening 330 of the space forming member 300. Fixing holes 415 are optionally provided in the main body portion 410. The cover member 400 is made of metal and formed in a flat plate shape, but is not limited thereto and may be formed in any shape from any material, such as wood or resin.

[0024] Then, as shown in FIG. 3( b), the cover member 400 is placed on the front surface side of the recess 200, so that the cover member-side opening 420 of the cover member 400 overlaps the opening 330 of the space forming member 300. Then, as shown in FIG. 3( c), a space is created between the back surface 412 of the cover member 400 and the space forming member 300, where a finger can be placed, and the back surface 412 forms a finger hook 460. When operating the plate material 100, such as when opening or closing a door, a finger can be inserted inside the cover member-side opening 420 of the cover member 400 and the finger can be securely placed on the finger hook 460 on the back surface 412. In particular, even if the plate material 100 is thin, the back surface 412 of the cover member 400 can reliably form the finger hook 460. Thus, according to the handle structure P of the present invention, the finger hook 460 can be reliably secured regardless of the thickness of the plate material 100.

[0025] 3(b), the finger hooks 460 are formed on both sides (the left side X1 and the right side X2 in the drawing) of the cover member side opening 420, but are not limited to this, and the finger hooks 460 may be formed on at least one side (the left side X1 or the right side X2 in the drawing) of the cover member side opening 420. Furthermore, the finger hooks 460 are formed on both sides (the left side X1 and the right side X2 in the drawing) of the cover member side opening 420, but are not limited to this, and the finger hooks 460 may be formed at any position as long as it is at least a part of the periphery of the cover member side opening 420 (for example, the upper side X3, the lower side X4, the left side X1, or the right side X2).

[0026] 3, in the handle structure P of the present invention, the space forming member 300 is attached to the recess 200 of the plate material 100, but the present invention is not limited to this, and the space forming member 300 does not have to be attached to the recess 200. In this case, the cover member 400 is attached directly onto the recess 200, and the cover member-side opening 420 of the cover member 400 is overlapped with the opening 210 of the recess 200. A space is then created between the back surface 412 of the cover member 400 and the recess 200 where a finger can be placed, and the back surface 412 forms a finger hook portion 460.

[0027] Note that the cover member 400 is fixed to the plate material 100 so as to cover the space forming member 300, and therefore, the space forming member 300 housed inside the plate material 100 can be effectively prevented from falling off from the plate material 100. Furthermore, as shown in FIG. 3(c), the space forming member 300 abuts against the back surface of the cover member 400, and therefore, rattle of the space forming member 300 in the front-to-rear direction can be prevented. Furthermore, the cover member 400 is fixed to the plate material 100 by fixing members 470 such as rivets that pass through fixing holes 415 of the cover member 400 and fixing holes 101 of the plate material 100, but the method is not limited thereto, and the cover member 400 may be fixed to the plate material 100 by any fixing method such as adhesive bonding or welding.

[0028] <Embodiment 2> Next, a handle structure PA according to a second embodiment of the present invention will be described with reference to Fig. 4. The handle structure PA according to the second embodiment differs from the handle structure P according to the first embodiment shown in Figs. 1 to 3 only in the shape of the cover member-side opening 420A of the cover member 400A, and other configurations are basically the same as the handle structure P according to the first embodiment, so detailed description will be omitted. Fig. 4(a) is an overall perspective view of the cover member 400A, and Fig. 4(b) is a front view of the handle structure PA.

[0029] 4(a), in a metal, flat-plate-shaped cover member 400A, a cover member-side opening 420A is substantially circular. The opening area of the cover member-side opening 420A is smaller than the opening area of the opening 210A of the recess 200A. Furthermore, the opening area of the cover member-side opening 420A is smaller than the opening area of the opening 330A of the space forming member 300A.

[0030] Then, as shown in FIG. 4(b), the cover member 400A is placed on the front surface side of the recess 200A, with the cover member-side opening 420A of the cover member 400A overlapping the opening 330A of the space forming member 300A. This creates a space between the back surface 412A of the cover member 400A and the space forming member 300A where a finger can be placed, and the back surface 412A forms a finger hook 460A. When operating the plate 100A, such as when opening or closing a door, a finger can be inserted through the cover member-side opening 420A of the cover member 400A and securely placed on the finger hook 460A on the back surface 412A. Thus, the handle structure PA of the present invention ensures a secure finger hook 460A regardless of the thickness of the plate 100A.

[0031] 4(b), since cover member side opening 420A has a substantially circular shape, finger hook 460A is formed around the entire periphery of cover member side opening 420A. Also, although cover member side opening 420A has a substantially circular shape, the shape is not limited thereto, and cover member side opening 420A may have any shape as long as finger hook 460A can be formed around a portion of the periphery of cover member side opening 420A.

[0032] <Embodiment 3> Next, a handle structure PB according to a third embodiment of the present invention will be described with reference to Fig. 5. The handle structure PB according to the third embodiment differs from the handle structure P according to the first embodiment shown in Figs. 1 to 3 only in the configuration of the cover member 400B, and other configurations are basically the same as those of the handle structure P according to the first embodiment, so detailed description will be omitted. Fig. 5(a) is an overall perspective view of the cover member 400B, and Fig. 5(b) is a front view of the handle structure PB.

[0033] 5(a), the cover member 400B includes two flat metal cover member pieces 480B. A front surface 481B and a back surface 482B of the cover member pieces 480B are flat. The cover member pieces 480B may also optionally have fixing holes 485B for fixing the cover member pieces 480B to the plate material 100B with rivets or the like.

[0034] As shown in FIG. 5(b), the cover member piece 480B of the cover member 400B is positioned on the front surface side of the recess 200B so as to overlap a portion of the opening 330B of the space forming member 300B. This creates a space between the back surface 482A of the cover member piece 480B and the space forming member 300B where a finger can be placed, and the back surface 482B forms a finger hook 460B. When operating the plate 100B, such as when opening or closing a door, a finger can be inserted through a portion of the opening 330B that is not covered by the cover member piece 480B and the finger can be securely placed on the finger hook 460B. Thus, the handle structure PB of the present invention ensures that the finger hook 460B is secure regardless of the thickness of the plate 100B.

[0035] 5(b), finger hooks 460B are formed on both sides of opening 330B by two cover member pieces 480B, but this is not limited thereto, and finger hooks 460B may be formed at any location as long as they are at least a portion of the periphery of opening 330B. Furthermore, while cover member 400B includes two cover member pieces 480B, this is not limited thereto, and cover member 400B may include one cover member piece 480B, or three or more cover member pieces 480B, as long as cover member 400B includes at least one cover member piece 480B. Furthermore, cover member piece 480B has a substantially rectangular shape, but this is not limited thereto, and cover member piece 480B may have any shape as long as it can overlap with a portion of opening 330B of space forming member 300B to form finger hooks 460B.

[0036] 5, in the handle structure PB of the present invention, the space forming member 300B is attached to the recess 200B of the plate material 100B. However, the present invention is not limited to this, and the space forming member 300B does not have to be attached to the recess 200B. In this case, the cover member 400B is attached directly onto the recess 200B, and the cover member piece 480B overlaps with a part of the opening 210B of the recess 200B. A space in which a finger can be placed is created between the back surface 482B of the cover member piece 480B and the recess 200B, and the back surface 482B forms the finger hook portion 460B.

[0037] <Embodiment 4> Next, a handle structure PC according to a fourth embodiment of the present invention will be described with reference to Fig. 6(a). Note that the handle structure PC according to the fourth embodiment differs from the handle structure P according to the first embodiment shown in Figs. 1 to 3 only in that it does not include a cover member 400 and that the space forming member 300C includes a finger hook portion 380C. Since the other configurations are basically the same as those of the handle structure P according to the first embodiment, detailed description will be omitted. Note that Fig. 6(a) is a cross-sectional view showing the handle structure PC, similar to Fig. 3(c).

[0038] As shown in FIG. 6(a), the space-forming member 300C has finger hooks 380C on both sides of the opening 330C, each of which is convex toward the opening 330C. The finger hooks 380C are flush with the surface of the plate 100C. A space for hooking a finger is provided on the back surface 382C of the finger hook 380C. When operating the plate 100C, such as when opening or closing a door, a finger can be inserted inside the opening 330C and securely hooked on the back surface 382C of the finger hook 380C. Thus, the handle structure PC of the present invention can reliably secure a finger hook regardless of the thickness of the plate 100C. In particular, unlike the handle structure P of embodiment 1 shown in FIG. 3, the handle structure PC of embodiment 4 can reliably secure a finger hook without using a cover member 400.

[0039] Although the space forming member 300C includes two finger hooks 380C on both sides of the opening 330C, the present invention is not limited thereto, and any number of finger hooks 380C may be provided at any location on at least a portion of the periphery of the opening 330C, such as providing one finger hook 380C on only one side of the opening 330C or providing finger hooks 380C continuously around the entire periphery of the opening 330C. Furthermore, the finger hook 380C has a flat plate shape, but the present invention is not limited thereto, and the finger hook 380C may have any shape as long as it is convex toward the opening 330C and allows fingers to be hooked thereon.

[0040] <Embodiment 5> Next, with reference to Fig. 6(b), a handle structure PD according to embodiment 5 of the present invention will be described. Note that the handle structure PD according to embodiment 5 differs from the handle structure P according to embodiment 1 shown in Figs. 1 to 3 only in that the recess 200D is a through-hole that also has an opening 210D on the back surface, that the space forming member 300D has an opening 330D on the back surface, and that a cover member 400D is also provided on the back surface. Since the other configurations are basically the same as those of the handle structure P according to embodiment 1, detailed description thereof will be omitted. Note that Fig. 6(b) is a cross-sectional view showing the structure of the handle structure PD, similar to Fig. 3(c).

[0041] As shown in FIG. 6(b), recess 200D is a through-hole penetrating plate 100D and has openings 210D on both the front and back surfaces. Space-forming member 300D, disposed inside recess 200D, has openings 330D on both the front and back surfaces, forming a frame-like structure surrounded by sidewalls 320D. Cover member 400D has the same structure as cover member 400 shown in FIG. 3, and is disposed on both the front and back surfaces of recess 200D, with cover member-side opening 420D of cover member 400D overlapping opening 330D of space-forming member 300D. A space is then created between cover member 400D and space-forming member 300D on the back surface 412D, forming a finger-hook portion 460D. When operating plate 100D, such as when opening or closing a door, a finger can be inserted from either the front or back side through cover member-side opening 420D of cover member 400D and then securely hooked on finger hook 460D on back surface 412D. In this way, with handle structure PD of the present invention, finger hook 460D can be reliably secured regardless of the thickness of plate 100D.

[0042] <Embodiment 6> Next, a handle structure PE according to a sixth embodiment of the present invention will be described with reference to Fig. 7. The handle structure PE according to the sixth embodiment differs from the handle structure P according to the first embodiment shown in Figs. 1 to 3 only in the structure of the space forming member 300E, and other configurations are basically the same as the handle structure P according to the first embodiment, so detailed description will be omitted. Fig. 7(a) is an overall perspective view of the space forming member 300E, and Fig. 7(b) is a cross-sectional view showing the structure of the handle structure PE, similar to Fig. 3(c).

[0043] The space forming member 300E includes a bottom wall 310E and side walls 320E rising from both sides of the bottom wall 310E, and is configured from an extruded member in the shape shown in FIG. 7(a). An opening 330E is formed on the opposite side of the bottom wall 310E. Furthermore, finger hooks 380E are provided on both sides of the opening 330E, each of which has a convex shape that faces the opening 330E. Furthermore, a protrusion 390 is provided on the opposite side of the finger hook 380E, protruding outward from the side wall 320E. A fixing hole 391E is provided in the protrusion 390.

[0044] As shown in FIG. 7(b), when the space forming member 300E is accommodated in the recess 200E, the protrusion 390E covers a portion of the surface layer 130E of the plate material 100E. The space forming member 300E is fixed to the plate material 100E by inserting a fixing member 392E, such as a screw, into the fixing hole 391E of the protrusion 390E and penetrating it to the surface layer 130E. The space forming member 300E is formed by bending, and as shown in FIG. 7(a), a side wall 320E, a finger hook 380E, and a protrusion 390E may be provided on one pair of sides of the bottom wall 310E, while the side wall 320E, the finger hook 380E, and the protrusion 390E may not be provided on the other pair of sides of the bottom wall 310E. Furthermore, when the space forming member 300E is formed by bending, the protrusion 390E may not be provided. In other words, one pair of sides of the bottom wall 310E may be provided with only the side wall 320E and the finger hook 380E, and the other pair of sides of the bottom wall 310E may not be provided with the side wall 320E, the finger hook 380E, or the protrusion 390E.
