Embodiments for Carrying Out the Invention

[0010] Hereinafter, Embodiment 1 and Embodiment 2 of the present invention will be described with reference to the drawings (Figs. 1 to 6). [Embodiment 1] (Figs. 1, 2, 3A, 3B, 4A, 4B) Referring to Figs. 1 to 4B, the sliding door handle 1 and the sliding door 3 according to Embodiment 1 of the present invention will be described. In Figs. 1 and 2, the intermediate portion in the vertical direction is relatively scaled down for convenience. Fig. 1 is an exploded perspective view showing an overview of the separated state before assembling the sliding door handle 1 and the sliding door 3 according to Embodiment 1 of the present invention. Fig. 2 is an overview perspective view showing an overview of the assembled state of the sliding door handle 1 and the sliding door 3 shown in Fig. 1. The sliding door handle 1 and the sliding door 3 are connected to each other and assembled to function as the sliding door 3. Fig. 3A is a connection schematic diagram schematically showing a first example of the connection state where the base portion 10 and the handle portion 12 of the sliding door handle 1 shown in Fig. 1 mesh with each other. Fig. 4A is a connection schematic diagram schematically showing a second example of the connection state where the base portion 10 and the handle portion 12 of the sliding door handle 1 shown in Fig. 1 mesh with each other. In Figs. 3A and 4A, the hatching is omitted.

[0011] The sliding door handle 1 is attached to the sliding door 3 in order to pull out the sliding door 3 from a sliding door accommodating wall portion 50 (see FIGS. 5A, 5B, and 6) that accommodates the sliding door 3 moving in the lateral direction. The attachment of the sliding door handle 1 to the sliding door 3 is achieved by fastening and fixing a substrate portion 14 (base portion 10) to a sliding door end portion 31 (sliding door 3) via a fastening fitting 26. In FIG. 2, the fastening fitting 26 is hidden by the handle substrate portion 18. The sliding door handle 1 includes a base portion 10 fixed to a pull-out side sliding door end portion 31 of the sliding door 3, and a handle portion 12 that meshes with the base portion 10 and is located between the upper and lower ends of the sliding door end portion 31 and is pulled out when the sliding door 3 is pulled out. The base portion 10 includes a substrate portion 14 connected to the sliding door end portion 31, and substrate end protruding portions 16 protruding from both lateral ends of the substrate portion 14 toward the handle portion 12. The handle portion 12 includes a handle substrate portion 18 positioned to face the substrate portion 14, outer protruding portions 20 protruding from both lateral ends of the handle substrate portion 18 along the outside of the substrate end protruding portions 16, a partition protruding portion 22 protruding in a partition shape in a direction opposite to the base portion 10 at the center in the lateral direction of the handle substrate portion 18, and a finger hook portion 24 extending horizontally to the left and right at the tip of the partition protruding portion 22 where a human finger can be hooked.

[0012] In the connection of the base portion 10 and the handle portion 12, the substrate end protruding portion 16 includes a substrate end protruding convex portion 17 that meshes with the outer protruding portion 20, the outer protruding portion 20 includes an outer protruding convex portion 21 that meshes with the substrate end protruding portion 16, and the substrate end protruding convex portion 17 and the outer protruding convex portion 21 mesh with each other. The connected state in which the base portion 10 and the handle portion 12 mesh has two cases as shown in FIGS. 3A (the first example) and FIGS. 4A (the second example). The connection regions surrounded by the circular two-dot chain lines in FIGS. 3A and FIGS. 4A are respectively enlarged and shown as FIGS. 3B and FIGS. 4B. FIG. 3B is a partial enlarged cross-sectional view showing an enlarged connection state of a substrate end protruding convex portion 17 (substrate end protruding convex portion 17s) of the substrate portion 14 and an outer protruding convex portion 21 (outer protruding convex portion 21s) of the outer protruding portion 20 in the first example shown in FIG. 3A. Figure 4B is a partially enlarged cross-sectional view showing an enlarged view of the connection between the substrate edge protrusion 17 (substrate edge protrusion 17d) of the substrate portion 14 and the outer protrusion 21 (outer protrusion 21d) of the outer protrusion 20 in the second example shown in Figure 4A. In Figures 3B and 4B, hatching is omitted, similar to Figures 3A and 4A. When it is not necessary to distinguish between the substrate edge protrusion 17s and the substrate edge protrusion 17d, it shall simply be referred to as the substrate edge protrusion 17. When it is not necessary to distinguish between the outer protrusion 21s and the outer protrusion 21d, it shall simply be referred to as the outer protrusion 21.

[0013] In the sliding door handle 1, the base plate end projection 17 and the outer projection 21 are sawtooth-shaped in a cross-section (horizontal plane) in the transverse direction intersecting the vertical direction. In a cross-section (horizontal plane) in the transverse direction intersecting the vertical direction, the interlocking between the base plate end projection 17 and the outer projection 21 is sawtooth-shaped, making it easy to achieve a secure interlocking. The substrate edge protrusion 17s and the outer protrusion 21s each have a single right-angled triangle (Figure 3B). The sawtooth interlocking between the substrate edge protrusion 17s and the outer protrusion 21s is achieved by a single right-angled triangle, making it easy to determine the strength of the interlocking. The substrate edge projection 17d and the outer projection 21d each have multiple triangles (Figure 4B). The sawtooth-like interlocking between the substrate edge projection 17d and the outer projection 21d is achieved by multiple triangles, making it easy to position and fix the interlocking parts smoothly. Preferably, the base portion 10 is made of synthetic resin and the handle portion 12 is made of metal. Since the base portion 10 is made of synthetic resin and the handle portion 12 is made of metal, the substrate edge protrusions 17 (substrate edge protrusions 17s, substrate edge protrusions 17d) are made of synthetic resin and the outer protrusions 21 (outer protrusions 21s, outer protrusions 21d) are made of metal, making it easier to achieve smooth interlocking with a sawtooth shape.

[0014] The sliding door handle 1 is equipped with a base portion 10 and a handle portion 12 to ensure physical strength, thus making it easy to achieve safety and reliability. Furthermore, the handle portion 12 covers the base portion 10, and the front of the finger rest portion 24 and the handle base portion 18 are visible as the handle portion 12, making it easy to achieve an aesthetically pleasing design. In addition, since the handle portion 12 is positioned vertically from the upper end to the lower end of the sliding door end portion 31, it is easy to grip with your fingers regardless of the position of your fingers in the vertical direction, thus improving the convenience of pulling out the sliding door 3. The handle portion 12 and the screen projection portion 22 are positioned along almost the entire length of the sliding door end portion 31. Therefore, the sliding door handle 1 is attached to the sliding door end portion 31 of the sliding door 3 to ensure physical strength, enhance safety and reliability, facilitate finger gripping to improve the operability of the sliding door, and easily improve the convenience of the sliding door.

[0015] [Embodiment 2] (Figures 5A, 5B, 6) Referring to Figures 5A to 6, the sliding door handle 1, sliding door 3, and opening / closing door 5 according to Embodiment 2 of the present invention will be described. In Embodiment 1, the fastening fitting 26 was disclosed in Figure 1, but in this embodiment, a cross-sectional conceptual diagram including the fastening fitting 26 is shown to supplement the explanation. Furthermore, the screw space 33 and finger gap 35, which were omitted from the explanation in Embodiment 1, will also be described. Note that the sliding door handle 1 and sliding door 3 in Embodiment 1 are the same as the sliding door handle 1 and sliding door 3 in this embodiment, so they are given the same reference numerals and their explanations will be omitted as appropriate. Figure 5A is a conceptual cross-sectional view showing the state in which the sliding door 3 is housed in the sliding door housing wall 50 when the sliding door housing wall 50 is located on only one side as an opening and closing door 5 according to Embodiment 2 of the present invention. Figure 5B is a conceptual cross-sectional view showing the state in which the sliding door 3 is pulled out from the sliding door housing wall 50 in the opening and closing door 5 shown in Figure 5A. Figure 6 is a conceptual cross-sectional view showing the state in which a sliding door 3 is housed in a sliding door housing wall 50, when two sliding door housing wall sections 50 form a door pocket as an opening and closing door 5 according to Embodiment 2 of the present invention.

[0016] The sliding door storage wall section 50 has a structure for storing the sliding door 3 when it is not in use. The sliding door storage wall section 50 functions with at least one section. When there is one sliding door storage wall section 50 (Figures 5A and 5B), it is stored in a wall-like state, and the sliding door 3 takes the form of a single sliding door. When two sliding door storage wall sections 50 form a pair (Figure 6), they are normally held as a door pocket, and the sliding door 3 takes the form of a pocket door. Let me explain the fastening fitting 26. The base portion 10 (base plate portion 14) is fastened to the sliding door end portion 31 via a fastening fitting 26 in the center in the lateral direction (see Figure 1). The base portion 10 (base plate portion 14) is positioned and fixed to the sliding door end portion 31 at the center in the horizontal direction, improving the strength of the fastening and making it easier to ensure reliability. The screw holes are located on the base portion 10 opposite the screw heads 28 (omitted in Figure 1). The fastening fittings 26 are arranged at least at two locations on the top and bottom of the base plate portion 14 (base portion 10) (see Figure 1). If necessary, additional fasteners may be added in the middle of the base plate portion 14 in the vertical direction. The fastening fitting 26 is a screw having a screw head 28. Since the fastening fitting 26 is a screw having a screw head 28, it is easy to ensure strength to the base portion 10 with an area corresponding to the screw head 28, and it is easy to ensure the fastening strength of the base portion 10 and achieve reliable fastening.

[0017] The substrate end projection 16 (substrate portion 14) and the outer projection 20 (pull handle substrate portion 18) form a screw space 33 for accommodating a screw head 28 between the base portion 10 and the pull handle substrate portion 18 when the substrate end projection 17 and the outer projection 21 are engaged (see Figures 3A and 4A). In other words, the screw space 33 is formed between the base portion 10 (substrate portion 14) and the pull handle portion 12 (pull handle substrate portion 18). Because a screw space 33 for accommodating a screw head 28 is formed, it is easy to effectively position a screw having a screw head 28 as a fastening fitting 26.

[0018] In the sliding door handle 1, the distance between the finger rest 24 and the sliding door storage wall 50 is provided with a finger gap 35 that allows a person's fingers to be inserted and removed (Figures 5A and 6). By setting the distance between the finger rest 24 and the sliding door storage wall 50 to a predetermined finger gap 35, it becomes easy to insert and remove a person's fingers between the sliding door storage wall 50 and the sliding door 3 (finger rest 24), thus making it easier to avoid a person's fingers getting caught between the sliding door storage wall 50 and the finger rest 24. In particular, even when operating the device without sufficient awareness of the finger gap 35 between the finger rest 24 and the sliding door storage wall 50, such as when a child is operating it, it is easier to avoid pinching one's fingers. For safety and design reasons, the finger gap 35 is preferably symmetrical with respect to the lateral center. The symmetrical finger gap 35 functions the same whether there is one or multiple sliding door housing walls 50.

[0019] The sliding door 3 according to this embodiment is a sliding door 3 (see Figure 2) that is housed in at least one sliding door housing wall 50 and has a sliding door handle 1 for pulling out at the sliding door end 31 on the pull-out side, and the sliding door handle 1 is the sliding door handle 1 according to Embodiment 1. Since the sliding door 3 is equipped with a sliding door handle 1 according to Embodiment 1, it is easy to ensure that it is easy to operate, and the safety, convenience, and aesthetics (design) of the sliding door 3 are easily improved. The sliding door storage wall section 50 only needs to consist of at least one sliding door storage wall section 50. When two are used to form a pair, they are usually understood as a door pocket (see Figure 6). When there is only one sliding door storage wall section 50, it is stored in a wall-like state (see Figures 5A and 5B). Sliding door 3 ensures physical strength for safety and reliability, and is equipped with a handle that makes it easy to grip, thus improving convenience.

[0020] The opening and closing door 5 according to this embodiment comprises at least one sliding door housing wall 50, a sliding door 3 housed in the sliding door housing wall 50, and a sliding door handle 1 attached to the sliding door 3. In other words, the sliding door 3 in the opening and closing door 5 is the sliding door 3 according to this embodiment. The opening and closing door 5 includes a sliding door housing wall 50 that accommodates the sliding door 3 equipped with a sliding door handle 1 according to Embodiment 1, making it easy and precise to open and close the sliding door 3, and ensuring safety, reliability, convenience, and even aesthetic appeal (design) as a door. The opening and closing door 5 ensures physical strength to enhance safety and reliability, and is equipped with a sliding door handle 1 and sliding door 3 that make it easy to grip, thus improving convenience.
