[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the following embodiment is one form for embodying the present invention, and is not intended to limit the scope of the present invention.

[0018] FIG. 1 is a schematic diagram showing an installation state of an opening / closing body (sliding door) device 100 of the present embodiment, and shows a door roller transparently relative to a rail. The opening / closing body device 100 of this embodiment is configured by suspending an opening / closing body (sliding door) 1 having roller units 2a, 2b at the top from a rail 3 installed above an opening A formed in a wall surface W or the like. The provision of a suspended opening / closing body (sliding door) using rollers that can run on a rail is the same as in the past, so a description of the rail configuration and installation in the opening will be omitted here. In the following, the width direction of the opening / closing body 1 (left and right direction in FIG. 1) will be simply referred to as the "width direction," and the thickness direction of the opening / closing body 1 (direction perpendicular to the paper surface in FIG. 1) will be simply referred to as the "thickness direction." The up-down direction (or height direction) is the up-down direction in FIG.

[0019] Fig. 2 shows the opening / closing body (suspension-type sliding door) 1 of this embodiment, with Fig. 2(a) being a front view, Fig. 2(b) being a side view of the door leading side, Fig. 2(c) being a side view of the door trailing side, Fig. 2(d) being a top view, and Fig. 2(e) being a bottom view. Note that the front view of Fig. 2(a) shows the state in which the bracket members 2a3 and 2b3 of the door roller units 2a and 2b and the lock metal fittings (end metal fittings) 4 are attached, while the other Figs. 2(b) to (e) show the state in which these members are not attached. The opening and closing body 1 is A first surface material 11a and a second surface material 11b are made of metal and joined together to form the outer shape of the opening / closing body 1; A roller unit 2a, 2b having a box portion 22 and a roller portion 21 (see FIG. 6 ), A first core member 12a is disposed between the first surface material 11a and the second surface material 11b on the door tip side of the upper part of the opening / closing body 1 and has a roller mounting recess 121 for receiving a box portion 22 of the roller unit; A second core member 12b is disposed between the first surface member 11a and the second surface member 11b on the door trailing side of the upper part of the opening / closing body 1 and has a roller mounting recess 121 for receiving a box portion 22 of the roller unit; A lock fitting (end fitting) 4 provided on the end surface of the door end side; A back plate member 14 for mounting the lock fitting 4; a lower support rib 13 extending in the width direction at the lower part of the opening / closing body 1 between the first surface material 11a and the second surface material 11b; a core material (not shown) disposed entirely between the first surface material 11a and the second surface material 11b; It is equipped with:

[0020] The opening / closing body 1 of this embodiment is essentially a metal opening / closing body composed of metal (steel) surface materials (first surface material 11a, second surface material 11b) and metal (steel) support bones (lower support bone 13). The opening / closing body 1 of this embodiment does not have a frame-shaped strength rib that is normally provided in conventional opening / closing bodies (it has no strength ribs other than the lower strength rib 13), but instead has first and second core members 12a and b, which will be described below, on the upper door leading side and door trailing side (both upper corners). This makes it possible to use a door roller unit for wooden doors (a door roller unit with a box part with an adjustment function) in a metal opening / closing body. At the same time, the weight of the opening / closing body is reduced by eliminating the metal strength ribs on the upper part, door leading side, and door trailing side. In addition, with regard to the lock fittings (end fittings) that were conventionally attached to the ribs on the door end side, the adoption of the end fitting mounting structure described below has improved the mounting accuracy of the end fittings and made the installation work more efficient.

[0021] Figure 3 shows the first surface material 11a, with Figure 3(a) being a front view, Figure 3(b) being a side view of the leading side, Figure 3(c) being a side view of the trailing side, Figure 3(d) being a top view, and Figure 3(e) being a bottom view. The first surface material 11a has a front portion 111, a leading side portion 112, a trailing side portion 113, a top portion 114, and a bottom portion 115, and its basic form is roughly tray-shaped. The leading side portion 112, the trailing side portion 113, and the top portion 114 have a height of about half the thickness of the opening / closing body 1, excluding the cut-out portions. The bottom portion 115 is formed lower than the other side portions in order to form a guide recess that receives a lower guide pin 5 (see FIG. 1) that is provided on the floor surface to prevent the hanging sliding door from swinging, and has an open bottom configuration (guide recess).

[0022] The upper surface portion 114 is formed with a notch 1141a on its door-leading side for receiving the box portion 22 of the door roller unit 2a, and with a notch 1141b on its door-trailing side for receiving the box portion 22 of the door roller unit 2b. The width dimension of each notch is approximately the same as the width dimension of the box part with the bracket members attached (the notches are slightly larger), and the thickness dimension is approximately the same as half the thickness dimension of the box part of the door roller unit (the notches are slightly larger). That is, when the first surface material 11a and the second surface material 11b are joined, holes are formed that have a shape that matches the shape of the top surface of the box part of the door roller unit (the box part with the bracket members attached).

[0023] The door end side portion 112 has a bent portion 112f at its tip as a reinforcing structure. The door end side portion 112 has a notch 1121 formed at the top to accommodate the box portion 22 of the roller unit 2a, and a notch 1122 formed near the center (at a height suitable for mounting the lock fitting 4) to accommodate the lock fitting 4. The notch 1121 communicates with the notch 1141a, and its vertical dimension is approximately the same as the vertical dimension of the box part of the door roller unit (the notch is slightly larger), and its thickness dimension is approximately the same as half the thickness dimension of the box part of the door roller unit (the notch is slightly larger). The notch 1121 forms a hole shaped to fit the side shape of the box part of the door roller unit when the first surface material 11a and the second surface material 11b are joined. The vertical dimension of notch 1122 is approximately the same as the vertical dimension of mounting plate portion 44 of lock fitting 4 (the notch is slightly larger), and the thickness dimension is approximately the same as 1 / 2 the thickness dimension of mounting plate portion 44 of lock fitting 4 (the notch is slightly larger). Notch 1122 forms a hole shaped to fit the shape of the mounting plate portion of the lock fitting (the outer shape of the front) when surface material 11a and surface material 11b are joined. In addition, an upper positioning notch 112f1a and a lower positioning notch 112f1b for positioning the back plate member 14 are formed in the bent portion 112f of the door end side surface portion 112 (see FIG. 9). The upper positioning notch 112f1a and the lower positioning notch 112f1b will be described in detail later.

[0024] The trailing edge side surface portion 113 has a bent portion 113f at its tip end as a reinforcing structure. The door trailing side surface portion 113 is formed with a notch 1131 at the upper portion thereof for receiving the box portion 22 of the door roller unit 2b. The notch 1131 communicates with the notch 1141b, and its vertical dimension is approximately the same as the vertical dimension of the box part of the door roller unit (the notch is slightly larger), and its thickness dimension is approximately the same as 1 / 2 the thickness dimension of the box part of the door roller unit (the notch is slightly larger). The notch 1131 forms a hole shaped to fit the side shape of the box part of the door roller unit when the first surface material 11a and the second surface material 11b are joined.

[0025] The second surface material 11b has a similar (symmetrical) configuration to the first surface material 11a, and therefore a description thereof will be omitted here.

[0026] FIG. 4 shows the first core member 12a of this embodiment, where FIG. 4(a) is a perspective view, FIG. 4(b) is a side view of the door end side, and FIG. 4(c) is a top view. The first core member 12a has a shape like a rectangular parallelepiped with a portion cut out, and has a roller mounting recess 121 that receives the box portion 22 of the roller unit 2a, wall portions 122a, 122b located on both sides in the thickness direction of the roller mounting recess 121, and a door-end side recess 123 that is arranged to communicate with the roller mounting recess 121.

[0027] The roller mounting recess 121 is open on the top side and the door edge side at the corners of the core member 12a, and the dimensions in the width, thickness and height directions are approximately the same as the dimensions in the width, thickness and height directions of the box part of the roller unit (the recess is slightly larger). More specifically, the width direction dimension of the roller mounting recess 121 is shorter than the width direction dimension of the box part with the bracket member attached by the thickness of the first surface material 11a (and second surface material 11b) (this allows the side surface of the box part on the door edge side to be positioned flush with the surface material). The walls 122a, 122b that define the roller mounting recess 121 function as thickness direction positioning parts that define the position of the box part of the roller unit in the thickness direction (preventing rattling of the box part). The door-end recess 123 is a recess that receives the bent portion 112f at the tip of the door-end side surface portion 112 of the first surface material 11a (and the second surface material 11b).

[0028] The first core member 12a is made of wood, and in this embodiment is formed by bonding together three wooden plate-shaped members. Specifically, it is formed by bonding two rectangular plate-like members arranged on both sides in the thickness direction and an approximately L-shaped plate-like member arranged so as to be sandwiched between them. As can be understood from the above description of the roller mounting recess 121, the approximately L-shaped plate-like member has a thickness dimension that is approximately the same as the thickness dimension of the box part (the plate-like member is slightly larger), and the width dimension of the approximately L-shaped plate-like member is smaller than the width dimension of the two rectangular plate-like members by the depth of the door end side recess 123 (equal to or greater than the height of the bent part 112f). The height dimension is the same as the height dimension of the two rectangular plate-like members. The dimension of the part cut out to form the L shape corresponds to the dimension of the roller mounting recess 121 described above. The thickness of each of the two plate-like members is approximately half the inner dimension between the first surface material 11a and the second surface material 11b in the thickness direction minus the thickness of the approximately L-shaped plate-like member. The width and vertical dimensions (i.e., the size of the rectangle when viewed from the front) are formed to a size that provides appropriate strength for the opening and closing body as a reinforcing material. In this way, by forming the core member by bonding three plate-shaped members of the above configuration, countersinking and the like are not required, and this improves work efficiency and reduces costs. Note that, although an example in which the core member is formed by bonding three plate-shaped members is given here, the present invention is not limited to this, and any forming method may be used. For example, the core member may be formed by cutting a block-shaped (rectangular parallelepiped) piece of wood, or the core member may be integrally molded from resin, etc. The first core member 12a of the above configuration "has the roller mounting recess having an inner dimension approximately equal to the outer dimension of the box portion, and has a thickness approximately equal to the inner dimension in the thickness direction between the first surface material and the second surface material."

[0029] The second core member 12b has the same configuration as the first core member 12a (is arranged symmetrically), and therefore a description thereof will be omitted here.

[0030] FIG. 5 is a perspective view showing the door roller unit 2b. The door roller unit 2b has a door roller portion 21, a box portion 22, and a bracket member 23. The roller portion 21 is a roller portion that runs on a rail, and is connected to the box portion 22 via an axle member. The box portion 22 has therein a mechanism for moving (adjusting) the shaft member connecting the roller portion 21 in the height direction and width direction. The bracket member 23 has a structure for sliding engagement with the box portion 22, and the bracket member 23 is screwed to the opening / closing body and the box portion 22 is engaged therewith, whereby the roller unit 2b is attached to the opening / closing body. The roller unit 2b itself may be any roller unit having a box portion, such as a commonly used roller unit for wooden doors, and further explanation thereof will be omitted here. The roller unit 2a is different from the roller unit 2b in that it has a soft-close mechanism 24 for soft-closing (see FIG. 6), but other configurations are the same as those of the roller unit 2b. In this embodiment, the roller unit 2a has a soft-close function, but the roller unit 2a may not have the soft-close function.

[0031] 6A to 6C are diagrams showing the vicinity of the upper portion of the opening / closing body 1 of this embodiment, with FIG. 6(a) being a front view, FIG. 6(b) being a side view of the door end side, and FIG. 6(c) being a top view. The first core member 12a and the second core member 12b described above are disposed between the first surface material 11a and the second surface material 11b at both corners on the upper leading and trailing ends. In this arrangement, the notches 1121 on the leading ends of the first surface material 11a and the second surface material 11b and the notches 1141a communicating therewith are aligned with the roller mounting recess 121 of the first core member 12a. Similarly, the notches 1131 on the trailing ends of the first surface material 11a and the second surface material 11b and the notches 1141b communicating therewith are aligned with the roller mounting recess 121 of the second core member 12b. The bracket members 23 of the roller units 2a, 2b are screwed into the roller mounting recesses 121 of the first core member 12a and the second core member 12b, which are made of wood, with wood screws, and the box portions 22 of the roller units 2a, 2b, whose roller portions 21 pass through the rail 3, are slidably fitted into the bracket members 23, thereby installing the opening / closing body 1.

[0032] FIG. 7 is an enlarged view of the lock attachment portion of the opening / closing body 1 of this embodiment, FIG. 7(a) is a front view, and FIG. 7(b) is a side view of the door end side. As mentioned above, conventionally, lock fittings have been attached to a strength rib on the door end side, but the opening / closing body 1 of this embodiment does not have a strength rib on the door end side, and the lock fittings 4 are attached using a back plate member 14 that is positioned relative to the first surface material 11a and the second surface material 11b. The lock fitting 4 has a main body 41 that houses the lock mechanism, a deadbolt 42, a cylinder portion 43, and a mounting plate portion (front) 44. Any lock fitting that is attached to the end face of an opening / closing body can be used, so further explanation will be omitted here.

[0033] 8A to 8C are diagrams showing the back panel member 14 of this embodiment, with FIG. 8(a) being a front view, FIG. 8(b) being a side view of the door end side, and FIG. 8(c) being a top view. The back plate member 14 is a substantially U-shaped member when viewed from above (FIG. 8(c)), and has a door-end side portion 141, a back portion 142, and a front portion 143. The door end side surface portion 141 is formed with an opening 1411 sized to receive the main body 41 of the lock fitting 4 (but not to allow the mounting plate portion (front) 44 to be inserted therethrough). Additionally, four notches are formed at the top and bottom of each of both ends of the opening 1411 in the thickness direction to form an upper tongue portion 1412a and a lower tongue portion 1412b. The upper tongue portion 1412a and the lower tongue portion 1412b face the back side of the mounting plate portion 44 of the lock fitting 4, and each has a screw hole H formed therein into which the mounting plate portion 44 of the lock fitting 4 is screwed. The upper tongue portion 1412a and the lower tongue portion 1412b are "end face fitting mounting portions in which screw holes for mounting an end face fitting are formed." The distance from the base of the upper tongue portion 1412a (the upper end of the notch on the upper side at both ends of the opening 1411) to the base of the lower tongue portion 1412b (the lower end of the notch on the lower side at both ends of the opening 1411) is approximately the same as the vertical length of the notches 1122 in the first surface material 11a and the second surface material 11b (i.e., approximately the same as the vertical dimension of the mounting plate portion 44 of the lock fittings 4). In this embodiment, the back plate member 14 is formed so that the vertical length L1 from the base of the upper tongue portion 1412a to the position where it contacts the upper positioning notch 112f1a and the vertical length L2 from the base of the lower tongue portion 1412b to the position where it contacts the lower positioning notch 112f1b are different lengths (in this embodiment, the upper side length L1 is shorter than the lower side length L2 as an example, but the upper side length L1 may also be longer than the lower side length L2).

[0034] The back plate member 14 in this embodiment is basically a member formed by cutting and bending a steel plate (shear press processing), but in order to form the vertical dimensions more precisely, the lower notch 1413 is formed by NC (cutting) processing. More specifically, in the shearing process, the steel plate is cut so that it has a larger vertical dimension than the vertical dimension between the alignment parts (notches 112f1a, 112f1b) of first surface material 11a and second surface material 11b described below, and then, by cutting, notches 1413 are formed so that L3 matches (is slightly smaller than) the vertical dimension between the alignment parts (notches 112f1a, 112f1b). In other words, by including "a step of cutting the parts that abut the height direction positioning parts after shearing in the formation of the back plate member", a more precise member is obtained. In this example, the lower part of the component is machined to precisely adjust the vertical dimensions, but the upper part of the component may be machined, or both the upper and lower parts of the component may be machined.

[0035] 9 is an enlarged view of the portion of the surface material where the back plate member is attached, to explain the interrelationship of the engagement between the two. Note that, for the sake of understanding the structure, only the engagement between one surface material (second surface material 11b) and back plate member 14 is shown, but the engagement between first surface material 11a and back plate member 14 is based on the same concept. As shown in FIG. 9(a), an upper positioning notch 112f1a and a lower positioning notch 112f1b for positioning the back panel member 14 are formed in the bent portion 112f of the door-end side surface portion 112 of the second surface material 11b.

[0036] The upper positioning notch 112f1a is configured to abut against the upper end of the back plate member 14 and the door end side surface portion 141. This allows it to function as a "height direction positioning portion that determines the vertical position of the back plate member" and a "width direction positioning portion that determines the width direction position of the back plate member". It also functions as an "upper positioning notch that determines the position of the end metal fittings on the upper side". The vertical length of the upper positioning cutout 112f1a is formed to be approximately the same as the length L1 (see FIG. 8) of the above-mentioned back plate member 14. Also, the widthwise length of the upper positioning cutout 112f1a is formed so that the widthwise dimension L4 of the remaining cut-out bent portion 112f is approximately the same as the plate thickness of the mounting plate portion 44 of the lock fitting 4 (thereby, the mounted lock fitting 4 is installed flush with the door-end side surface portion 112 of the second surface member 11b).

[0037] The lower positioning notch 112f1b is configured to abut against the lower end (notch 1213) of the back plate member 14 and the door end side surface portion 141. This allows it to function as a "height direction positioning portion that determines the vertical position of the back plate member" and a "width direction positioning portion that determines the width direction position of the back plate member". It also functions as a "lower positioning notch that determines the position of the end metal fitting on the lower side". The vertical length of the lower positioning cutout 112f1b is formed to be approximately the same as the length L2 (see FIG. 8) of the above-mentioned back plate member 14. Also, the widthwise length of the lower positioning cutout 112f1b is formed so that the widthwise dimension L5 (the same dimension as L4) of the remaining cut-out bent portion 112f is approximately the same as the plate thickness of the mounting plate portion 44 of the lock fitting 4 (thereby, the mounted lock fitting 4 is installed flush with the door-end side surface portion 112 of the second surface member 11b).

[0038] As described above, the length L1 and the length L2 of the back plate member 14 are configured to be different lengths, and therefore the lengths in the up-down direction of the upper positioning cutout 112f1a and the lower positioning cutout 112f1b are also different. This configuration prevents the back plate member 14 from being mistakenly attached upside down. In this embodiment, the lengths L1 and L2 of the back plate member 14 and the vertical lengths of the upper positioning notch 112f1a and the lower positioning notch 112f1b are different, but the present invention is not limited to this, and the lengths L1 and L2 of the back plate member 14 and the vertical lengths of the upper positioning notch 112f1a and the lower positioning notch 112f1b may be the same.

[0039] The lower support bone 13 is a metal (steel) member that is substantially U-shaped with an opening on the lower side in a cross-sectional view. The lower support bone 13 is similar in concept to the lower support bones provided in conventional opening and closing bodies, so further explanation will be omitted here.

[0040] Next, an overview will be given of the assembly process of the opening / closing body 1 of this embodiment having the above-mentioned components.

[0041] The assembly of the components having the above-described configurations is generally carried out through the following steps. 1. Step of laying either the first surface material 11a or the second surface material 11b flat (laying the front part 111 down) 2. The step of placing the core material on the surface material (inside). 3. Step of arranging the first core member 12a and the second core member 12b at the corners of the upper door leading side and the upper door trailing side. 4. Step of arranging the back plate member 14 so as to be positioned with respect to the upper positioning notch 112f1a and the lower positioning notch 112f1b 5. Step of placing the lower bone 13 at the bottom 6. Step of covering the first surface material 11a (or the second surface material 11b) with the second surface material 11b (or the first surface material 11a) to bond the first surface material 11a and the second surface material 11b together. 7. Step of attaching the lock fitting (end fitting) 4 to the back plate member 14 8. Step of attaching the bracket members 23 to the roller attachment recesses 121 of the first core member 12a and the second core member 12b. 9. Step of attaching the door roller units 2a, 2b on the door leading side and the door trailing side by attaching the box part 22 to the bracket member 23 while inserting the box part 22 into the door roller attachment recesses 121 of each of the first core member 12a and the second core member 12b. In addition, the order of the steps of arranging the respective members in steps 2 to 5 above may be arbitrary. Step 8 can be performed at any timing between the time when the core member is formed and the time when the roller unit is attached (the roller unit can be attached in advance when the core member is formed). Steps 1-6 are basically work carried out in a factory, but steps 7-9 can be carried out at the installation site (particularly step 9, as mentioned above, is carried out at the installation site when the opening / closing body 1 is installed by slidingly fitting the box portions 22 of the roller units 2a, 2b, whose roller portions 21 are passed through the rail 3, into each of the bracket members 23).

[0042] Regarding step 2, the core material in this embodiment is a structure in which a large number of paper-made cylindrical bodies having a central axis in the thickness direction are joined in the planar direction in the width-height direction (not shown). The core material reinforces the first surface material 11a and the second surface material 11b to prevent them from becoming dented, and may be any material having this function (for example, a filler made of urethane foam, etc.).

[0043] Prior to the arrangement of the first core member 12a and the second core member 12b in step 3, the molding of the core members described above has of course been carried out, and therefore the "step of forming the first core member and the second core member, which have the wheel mounting recess with inner dimensions approximately the same as the outer dimensions of the box portion, and have a thickness approximately the same as the inner dimension in the thickness direction between the first surface material and the second surface material" has also been carried out. Furthermore, if the bracket members 2a3, 2b3 are attached to the first core member 12a and the second core member 12b in advance before installation on the surface material (by performing the work of step 8 in advance), the work will be easier than attaching the bracket members after the core members are assembled as opening / closing bodies.

[0044] Prior to the placement of the back plate member 14 in step 4, the back plate member 14 is pre-formed with screw holes H into which the mounting plate portion 44 of the lock fitting 4 is screwed, which makes the work easier than drilling screw holes after the back plate member is assembled as an opening / closing body. By positioning the back plate member 14 with respect to the upper positioning notch 112f1a and the lower positioning notch 112f1b, "positioning based on the height direction positioning portion" and "positioning based on the width direction positioning portion" are performed.

[0045] In this embodiment, the first surface material 11a and the second surface material 11b are joined together by adhesive (pressing and bonding) in step 6. In addition to step 6, adhesive is applied to each component as necessary when arranging each component in steps 2-5. In this embodiment, the components are fixed by adhesion, but the present invention is not limited to this, and any fixing method may be used (for example, welding or screwing may be used for some components).

[0046] As described above, according to the opening / closing body 1 and the manufacturing method thereof of the present embodiment, a roller unit including a box portion can be used in a metal opening / closing body. More specifically, it is possible to use commercially available roller units for wooden doors as they are in a metal opening and closing body. By forming the core member from a wood material, it is highly accurate and lightweight, and the roller units for wooden doors can be used as they are (they can be fastened with wood screws). Fig. 10 shows an example (near the upper part) of a conventional opening / closing body 200 made of metal. As shown in Fig. 10, the conventional opening / closing body 200 is equipped with an upper strength bone 201, a trailing-side strength bone 202, and a leading-side strength bone 203 made of steel (it also has a lower strength bone, not shown), and door rollers 205a and 205b are fastened (screwed using pop nuts) to the upper strength bone 201. In the opening / closing body 200 equipped with such an upper strength bone 201 made of steel, it is difficult to make it possible to install a door roller unit for a wooden door equipped with a box portion (it is difficult from the standpoint of economy, etc. to process a recess in a metal member to receive a door roller unit for a wooden door). In contrast, according to the opening / closing body 1 of the present embodiment, a roller unit having a box portion can be used in a metal opening / closing body. In addition, by using the core member, the strength bones are limited to the lower strength bones and other strength bones are eliminated, which leads to further weight reduction and cost reduction.

[0047] According to the opening / closing body 1 of this embodiment, the first core member 12a and the second core member 12b are the same member, and therefore, costs can be reduced by standardizing the parts. Also, since the first core member 12a and the second core member 12b are arranged at both ends, rather than being through members in the width direction like conventional strength ribs, the same members can be used even for variations in the width direction of the opening / closing body (in the case of through members like conventional strength ribs, separate members corresponding to differences in width are required), costs can be reduced from this viewpoint as well.

[0048] According to the opening / closing body 1 and its manufacturing method of the present embodiment, the mounting structure and mounting method for the lock fittings 4 can achieve low costs, high precision, and high work efficiency. 11 shows a strength frame 203 (a roughly U-shaped member in cross section) on the door-end side of a conventional metal opening / closing body 200. The conventional opening / closing body 200 is provided with the strength frame 203 on the door-end side, and this strength frame 203 is provided with an attachment structure for a locking metal fitting. In this attachment structure, an opening 2031 is formed on the side surface on the door-end side of the strength frame 203, and attachment pieces 204 are attached (welded) to the top and bottom of the opening 2031 on the back side of the side surface on the door-end side of the strength frame 203 so that the attachment pieces can be seen from this opening 2031. A screw hole for screwing in the locking metal fitting is formed in the attachment piece 204, but the formation of this screw hole needs to be performed after the strength frame 203 is assembled as an opening / closing body, which makes the work less efficient. This is because the reinforcing bars 203 placed inside the surface material are formed with a specified clearance taking into consideration their placement inside, and so their position relative to the surface material can vary slightly for each individual piece. Therefore, if the screw holes are formed first, the positional relationship of the screw holes to the surface material will also change slightly, which could make it impossible to attach the lock hardware. In contrast, according to the opening / closing body 1 and its manufacturing method of this embodiment, the positioning portion formed in the surface material described above allows the back plate member 14 to be positioned with high precision relative to the surface material, so that the screw holes H for screwing the mounting plate portion 44 of the lock fitting 4 can be formed in the back plate member 14 in advance, which is easier to work with than drilling screw holes after the back plate member is assembled as the opening / closing body. Furthermore, in the conventional opening / closing body 200, the attachment piece 204 is welded to the support frame 203, and the precision of the widthwise position of the attachment piece 204 peeking out from the opening 2031 relative to the surface material is not necessarily high. In order to make the surface material and the front of the lock hardware flush, the widthwise position of the attachment piece 204 is fine-tuned using pliers, for example. In contrast, according to the opening / closing body 1 of this embodiment, the back plate member 14 is directly positioned relative to the surface material, so that the positional accuracy relative to the surface material can be increased. In addition, in this embodiment, the portion protruding from the notch 1122 of the surface material is formed as a tongue portion (upper tongue portion 1412a, lower tongue portion 1412b) so that fine adjustment using pliers or the like is possible. As shown in FIG. 9, the position of the root portion of the upper tongue portion 1412a is approximately the same as the upper end of the notch 1122 (hole for receiving the lock metal fitting 4) of the surface material, so that the raised tongue portion is less likely to interfere with the bent portion 112f when fine adjustment (raising the tongue portion, etc.) is made using pliers or the like. Similarly, the position of the root portion of the lower tongue portion 1412b is approximately the same as the lower end of the notch 1122 of the surface material.

[0049] In the embodiment, the first surface material 11a and the second surface material 11b have the same (symmetrical) configuration, but the present invention is not limited to this, and in order to make an opening and closing body according to the concept described above, the first surface material and the second surface material may have a partially different structure. For example, as described below, a notch for positioning may be formed on only one side.

[0050] In the embodiment, the height positioning portion of the first surface material and the second surface material that defines the vertical position of the back plate member, and the width positioning portion that defines the width position of the opening and closing body of the back plate member are both formed by notches, but the present invention is not limited to this. For example, the height positioning portion and the width positioning portion may be formed by providing a protrusion on the first surface material and the second surface material that abuts against the back plate member to position it. In addition, in the embodiment, the height direction positioning portion and the width direction positioning portion are formed on both the first surface material 11a and the second surface material 11b as an example, but for example, the notch on one surface material may be formed as a notch with the precision required for a positioning portion and the notch on the other surface material may be formed slightly larger, or the function as a positioning portion may be configured only on one of the first surface material 11a or the second surface material 11b.

[0051] In the embodiment, the first core member 12a and the second core member 12b are the same member (arranged symmetrically on the leading and trailing sides), but the present invention is not limited to this, and the first core member 12a and the second core member 12b may have different structures. For example, the first core member 12a and the second core member 12b may have different structures depending on the difference in the peripheral structure on the leading and trailing sides, such as when the shapes of the roller unit on the leading side and the roller unit on the trailing side are different. In addition, in the embodiment, the first and second core members 12a, 12b are made of wood, but the present invention is not limited to this, and they may be made of resin, for example.

[0052] In the embodiment, the lock fitting 4 provided on the leading end face is shown as an example of an end fitting, but the present invention is not limited to this. For example, the mounting structure and method using the back plate member described above can be applied to any end fitting equipped with a mounting plate that is attached to any end face (leading end face, trailing end face, upper end face, lower end face) of an opening / closing body, such as a lift-down fitting (French drop) or an electrically conductive fitting (through which the wiring of an electric lock passes) provided on the trailing end face. In addition, although the embodiments show a sliding door as the opening / closing body, the mounting structure and method for the end fittings of the present invention are not limited to sliding doors, and the mounting using the back plate member described above can be applied to any opening / closing body, such as a hinged door. In addition, although the embodiment has been described as a structure and method for attaching an end metal fitting in a location where there is no strength rib, the attachment method using the back plate member described above can also be used when there is a strength rib. For example, by determining the relative shapes of the opening 2031 shown in Figure 11 and the back plate member of the present invention so that they do not interfere with each other, the structure and method for attaching an end metal fitting of the present invention can be used even when there is a strength rib.
