[Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described below with reference to the drawings (Figures 1 to 5). [Embodiment 1] (Figures 1, 2, and 3) A sliding door handle 1 and sliding door 3 according to Embodiment 1 of the present invention will be described with reference to Figures 1 to 3. Figure 1 is an exploded perspective view showing an overview of the separated state of the sliding door handle 1 and sliding door 3 according to Embodiment 1 of the present invention before assembly. Figure 2 is an overview perspective view showing the assembled sliding door handle 1 and sliding door 3 as shown in Figure 1. The sliding door handle 1 and the sliding door 3 are combined and connected to each other to function as the sliding door 3. Figure 3 is a schematic enlarged partial cross-sectional view showing the cross-sectional state in the direction of the arrow indicated by arrow symbol SF3 in Figure 2. In Figure 3, hatching for the sliding door handle 1 and fastening hardware 26 is omitted for clarity of the figure. The same applies to the following figures.

[0011] The sliding door handle 1 is attached to the sliding door 3 for pulling out the sliding door 3 from a sliding door accommodating wall portion 50 (see FIGS. 4A, 4B, and 5) that accommodates the sliding door 3 moving in the horizontal direction. The sliding door handle 1 is attached to the sliding door 3 by fastening and fixing a connecting portion 10 of the sliding door handle 1 to a sliding door end portion 30 of the sliding door 3 via a fastening fitting 26. The sliding door handle 1 includes a connecting portion 10 fixed to the sliding door end portion 30 from the upper end to the lower end of the pull-out side sliding door end portion 30 of the sliding door 3, a partition protruding portion 12 protruding in a partition shape in a direction opposite to the sliding door end portion 30 from the horizontal center of the connecting portion 10, and a finger hook portion 14 extending symmetrically left and right in the horizontal direction at the tip of the partition protruding portion 12 for a human finger to be hooked. The connecting portion 10 includes a pair of fixing portions 16 positioned and fixed by surface contact on both end sides in the horizontal direction of the sliding door end portion 30, and a pair of inclined portions 20 that form an isosceles triangular space 18 between the sliding door end portion 30 and the partition protruding portion 12 between the fixing portion 16 and the partition protruding portion 12. Either one of the inclined portions 20 includes a fastening portion 22 (FIG. 1) through which a fastening fitting 26 (FIG. 2) connected to the sliding door end portion 30 penetrates.

[0012] Since the sliding door handle 1 includes a connecting portion 10 fixed to the sliding door end portion 30 (the fixing portions 16 that are in face contact with both ends in the horizontal direction of the sliding door end portion 30), mechanical strength is ensured, and it is easy to achieve safety and reliability. The connecting portion 10 includes inclined portions 20 that form an isosceles triangular space 18 between the sliding door end portion 30 (fixing portion 16) and the partition protruding portion 12. The inclined portion 20 includes a fastening portion 22 through which the fastening fitting 26 penetrates. The sliding door handle 1 is fastened to the sliding door 3 in an inclined direction via the fastening fitting 26 that penetrates the fastening portion 22, so it is easy to ensure fastening strength, and it is easy to ensure the connection strength between the sliding door handle 1 and the sliding door 3 with a relatively simple structure. The finger hook portion 14 extends symmetrically left and right in the horizontal direction at the tip of the partition protruding portion 12 and is long in the longitudinal direction from the upper end to the lower end of the sliding door 3. Therefore, regardless of the position of the finger in the vertical direction, it is easy to hook the finger, and it is easy to improve the convenience of the operation of pulling out the sliding door 3. That is, the sliding door handle 1 ensures physical strength, achieves safety and reliability, and includes a finger hook portion 14 that facilitates finger hooking, making it easy to improve convenience. Since the finger hook portion 14 is positioned over substantially the entire vertical direction, it can be used regardless of a person's height, and it is easy to ensure convenience. Further, since it is positioned symmetrically left and right, it can be used regardless of the dominant hand, and it is easy to improve convenience. The screen protruding portion 12 is positioned over the entire vertical direction, similarly to the connecting portion 10. Incidentally, the fastening portion 22 is positioned as a through hole through which the fastening fitting 26 positioned on the inclined portion 20 passes.

[0013] The fixing portion 16 is positioned in a band shape from the upper end to the lower end of the sliding door end portion 30. Since the fixing portion 16 is positioned in a band shape from the upper end to the lower end on both end sides of the sliding door end portion 30, it is fixed in a band shape in the vertical direction with respect to the lateral ends of the sliding door end portion 30, and it is easy to ensure stable connection strength. The fixing portion 16 includes a claw portion 24 (FIG. 3) that sandwiches the side surface 32 of the sliding door end portion 30 at the tip. That is, since the fixing portion 16 includes the claw portion 24 that sandwiches the side surface 32 of the sliding door 3 (sliding door end portion 30), the positioning accuracy and fixing strength of the fixing portion 16 (sliding door handle 1) with respect to the sliding door 3 are ensured, and it is easy to improve the connectivity (fixing property) between the sliding door end portion 30 and the sliding door handle 1. The side surface 32 of the sliding door 3 (sliding door end portion 30) corresponds to the front and back planes of the sliding door 3 that intersect the sliding door end portion 30. The fastening fitting 26 is preferably fastened flush with the inclined portion 20. Since the fastening fitting 26 is vertically fitted into the inclined portion 20 to be flush, it is surely connected to the sliding door end portion 30, and it is easy to ensure the aesthetic sense of the inclined portion 20 and further the design property of the sliding door handle 1. Since the fastening fitting 26 is fastened flush with the sliding door handle 1 (inclined portion 20), it is fastened in a direction intersecting the sliding door end portion 30, and it is easy to improve the connection strength. Incidentally, the fastening fitting 26 is preferably a socket screw.

[0014] [Embodiment 2] (FIGS. 4A, 4B, 5) Referring to FIGS. 4A to 5, the sliding door handle 1, the sliding door 3, and the opening / closing fitting 5 according to Embodiment 2 of the present invention will be described. Since the sliding door handle 1, the sliding door 3, and the opening / closing fitting 5 are substantially the same as the sliding door handle 1, the sliding door 3, and (the opening / closing fitting 5) according to Embodiment 1, respectively, the same reference numerals are given and the description will be omitted as appropriate. Figure 4A is a partial cross-sectional view taken from the same position as in Figure 3, showing a state in which the sliding door handle 1 and the sliding door 3 are housed in the sliding door handle 50, in an opening / closing door 5 according to Embodiment 2 of the present invention, where the sliding door housing wall 50 is located on only one side. Figure 4B is a partial cross-sectional view showing the sliding door handle 1 and sliding door 3 pulled out from the sliding door housing wall 50 in the opening / closing door 5 shown in Figure 4A. Figure 5 is a partial cross-sectional view taken from the same position as in Figure 3, showing the state in which the sliding door 3 is housed in the 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, in the same position as in Figure 3.

[0015] 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 4A and 4B), it is stored in a wall-like state, and the sliding door 3 takes the form of a single sliding door. When there are two sliding door storage wall sections 50 forming a pair (Figure 5), they are normally perceived as a door pocket, and the sliding door 3 takes the form of a pocket door. In the sliding door handle 1, the distance between the finger rest 14 and the sliding door storage wall 50 is provided with a finger gap 36 that allows a person's fingers to be inserted and removed (Figures 4A and 5). By setting the distance between the finger rest 14 and the sliding door storage wall 50 to a predetermined finger gap 36, it becomes possible to insert and remove a person's fingers between the sliding door storage wall 50 and the sliding door 3 (finger rest 14), thus making it easier to avoid a person's fingers getting caught between the sliding door storage wall 50 and the finger rest 14. In particular, even when operating the device without sufficient awareness of the finger gap 36 between the finger rest 14 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 36 is preferably symmetrical with respect to the lateral center. The symmetrical finger gap 36 functions the same whether there is one or multiple sliding door storage walls 50.

[0016] 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 30 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 5). When there is only one sliding door storage wall section 50, it will be stored in a wall-like state (see Figures 4A and 4B). 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.

[0017] 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 related to the opening and closing door 5 is the sliding door 3 according to this embodiment. Since 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, the opening and closing of the sliding door 3 becomes easy and accurate, and safety, reliability, convenience, and even the aesthetic appeal (design) of the opening and closing door 5 are easily ensured. 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.
