[0003] [Patent Document 1] JP 2011-246898 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the conventional gate frame body described above usually protrudes in a corner shape from the inner edge of an opening in a building, wall surface, or ceiling surface. For this reason, a person or object passing through may come into contact with the protruding corner of the gate frame body, which may damage the protruding part or give an impact to the person or object that comes into contact with it. Therefore, for example, an angle-shaped buffer member may be attached to the protruding corner portion of the gate-shaped frame by double-sided tape or the like. However, according to such conventional technology, there is a risk that the angle-shaped buffer member may come off due to contact with a person or object, and the appearance is also undesirable. [Means for solving the problem]

[0005] In view of the above problems, one aspect of the present invention has the following configuration. A frame material for a structure that is provided along the inner edge of an opening in a structure, the frame material comprising a frame body extending along the inner edge of the opening, and a cushioning member provided on the frame body to cushion the impact of an object abutting against it from the outside, the frame material body having a plate-shaped protruding corner portion formed in a protruding corner shape, a notch portion cut into the plate-shaped protruding corner portion, and a fold-in portion folded inwardly along the notch portion, the cushioning member being fitted into a recess formed by the notch portion and the fold-in portion. Effect of the Invention

[0006] Since the present invention is configured as described above, it is possible to make the buffer member less likely to come off. [Brief description of the drawings]

[0008] Next, an embodiment of the present invention will be described in detail with reference to the drawings. In this specification, the term “inside the frame” refers to the inside of the frame body 10 which is configured in a gate shape or a rectangular frame shape, and the term “outside the frame” refers to the outside of the frame body 10 .

[0009] <First embodiment> FIG. 1 shows an example of a fitting device using a frame material for a structure according to the present invention. The fitting device 1 is attached to a passable opening in a structure X such as a building. This fitting device 1 comprises a frame body 10 attached along the inner edge of an opening in a structure X, and a door body 20 that opens and closes an opening 10a within this frame body 10, forming a hanging sliding door in which the door body 20 is suspended and slid laterally to open and close.

[0010] The frame body 10 comprises a structure frame material 11 which is a vertical frame facing the door end surface of the door body 20, a vertical frame 12 which is erected at a distance from the structure frame material 11 towards the door end direction, a vertical frame 13 which is erected at a further distance from the vertical frame 12 towards the door end direction, and a horizontal frame 14 which connects the upper ends of the structure frame material 11 and the vertical frames 12, 13 and covers the upper end side of the door body 20 which opens and closes.

[0011] The structure frame material 11 constitutes a vertical frame on the door-end side of the frame body 10, and is provided along the inner edge a1 (see FIG. 1) in the up-down direction of the opening of the structure X.

[0012] The vertical frame 12 near the center in the width direction passes through the door body 20 in a penetrating manner in the left-right direction. That is, according to Fig. 2, the door body 20 passes through the vertical frame 12 to the left to perform a closing operation, and passes through the vertical frame 12 to the right to perform an opening operation.

[0013] The vertical frame 13 on the door end side is located on the door end direction side within the door pocket 15 that houses the door body 20, and faces the door end portion of the door body 20 when the door is fully opened. The door pocket 15 is formed in a bag shape with an opening at the door end by the wall materials on both sides in the thickness direction of the door body and the vertical frame 13.

[0014] The horizontal frame 14 is provided in a long shape extending horizontally above the door body 20 so as to cover the upper end of the door body 20 that opens and closes. This horizontal frame 14 is sometimes called a crossbeam. The horizontal frame 14 has a generally inverted concave vertical cross section that is open downward and continues in the horizontal direction, and the upper end of the door body 20 is inserted into the interior of the horizontal frame 14. Inside the horizontal frame 14, a rail (not shown) is provided for suspending the hoist 22 of the door body 20 in a rotatable manner.

[0015] The door body 20 has a door body main body 21 which is a vertically long plate when viewed from the front, and a plurality of hoists 22 provided at the upper end of this door body main body 21. This door body 20 has a hoist 22 that is hung on a rail (not shown) within the horizontal frame 14 and rolls thereon, and moves laterally between a closed position in which it covers almost the entire area of ​​the opening 10a, and an open position (see Figure 1) in which it moves toward the door end and opens the opening 10a. In addition, the symbol 23 denotes a handle portion that is placed on and pulled left and right when opening and closing the door body 20.

[0016] The frame material 11 for a structure comprises a frame material main body 11a extending in the vertical direction along the inner edge a1 of the opening of the structure X, and a cushioning member 11b provided on this frame material main body 11a to cushion the impact of an object abutting against it from the outside (see FIG. 3).

[0017] The frame material main body 11a has a plate-shaped protruding corner portion 11a1 formed by bending a plate-shaped portion into a protruding corner shape, a notch portion 11a2 formed by cutting out this plate-shaped protruding corner portion 11a1, and a folded-in portion 11a3 (see Figures 2 to 8) formed by folding the plate-shaped portion inward along this notch portion 11a2. The frame body 11a is formed by bending and punching a flat raw plate material (not shown) to form the plate-shaped corners 11a1, the notches 11a2, the folded-in portions 11a3, and the like.

[0018] The plate-shaped corner portion 11a1 is located at a corner portion where the visible surface and the invisible surface of the frame body 10 intersect.

[0019] The cutout portion 11a2 is formed by cutting out a predetermined range of one of the plate-shaped corner portions 11a1 of the frame material 11 for a structure, straddling from the visible surface to the invisible surface, in a long shape extending in the vertical direction. The cutout portion 11a2 has a function of ensuring a space for storing the cushioning member 11b inside the frame material main body 11a (see FIG. 5), and a function of facilitating the bending process of the plate-shaped projected corner portion 11a1.

[0020] The folded-in portion 11a3 is formed by folding inward a plate-shaped portion on the front surface side of the frame body 11a. More specifically, a cutout portion 11a2 is formed in a plate-shaped raw material (not shown) for forming the frame material main body 11a. Then, at one end side and the other end side of the extension direction of this cutout portion 11a2 (the vertical direction according to FIG. 6), a notch 11a31 is provided that communicates with the cutout portion 11a2 and intersects with the extension direction of the cutout portion 11a2. The portions shaped like horizontally projecting plates in plan view (see FIG. 6) along the cuts 11a31, 11a31 and the notch 11a2 are bent inward at a substantially right angle (see FIG. 8) to form the folded-in portion 11a3.

[0021] The cutout portion 11a2 and the folded portion 11a3 configured as described above form an elongated recess 11a23 that continues in the vertical direction in a predetermined range near the lower end of the corner side of the frame material for a structure 11 (see Figs. 6 and 7). The cushioning member 11b is fitted into this recess 11a23.

[0022] The cushioning member 11b fits into the recess 11a23 so as to contact the folded-in portion 11a3. This cushioning member 11b is formed in a long rectangular parallelepiped shape extending in the vertical direction, and according to the example shown in Figures 3 to 5, it is formed so as to be approximately flush with the visible surface and the visible surface of the structure frame material 11. The cushioning member 11b is bonded to the folded portion 11a3 with an adhesive 11a5 (double-sided tape or adhesive).

[0023] The material of this buffer member 11b may be an elastic material having appropriate elasticity (for example, rubber or elastomer resin), or a low-resilience material (for example, low-resilience urethane foam).

[0024] <Action and effect> According to the above embodiment, even if a person or object attempting to pass through the opening 10a accidentally hits the frame material for the structure 11, the impact of the hit can be mitigated by the cushioning member 11b, thereby preventing damage to the frame material for the structure 11, the person, the object, etc. due to the hit. Moreover, since the buffer member 11b fits into the recess 11a23, it is unlikely to come off even if it receives an impact or if the adhesive portion deteriorates. Furthermore, by appropriately adjusting the depth of the recess 11a23, the thickness of the cushioning member 11b can be easily increased or decreased without increasing the amount by which the cushioning member 11b protrudes from the outer surface of the frame material main body 11a, thereby obtaining an excellent impact absorbing effect. Moreover, the sense of unity between the frame body 11a and the cushioning member 11b is improved, and the appearance is also good in terms of design. Moreover, the recesses 11a23 can be formed by bending or punching a plate-shaped raw material, and the workability is excellent.

[0025] <Second embodiment> Next, another example of a frame material for structures according to the present invention will be described. In addition, since the frame material for structures described below is a modified version of the frame material for structures 11 having the above-described configuration, the modified parts will mainly be described in detail, and parts that function in approximately the same way will be given the same symbols as the frame material for structures 11 described above.

[0026] A frame material for a structure 11A shown in FIG. 9 is obtained by replacing the buffer member 11b in the frame material for a structure 11 with a buffer member 11bA. The buffer member 11bA is set to have a larger vertical dimension and horizontal dimension in cross section than the above-mentioned frame material for structure 11. When the buffer member 11bA is fitted into the recess 11a23, the exposed surface located on the outside of the frame material for structure 11 protrudes outward from the visible surface and the visible surface of the frame material for structure 11.

[0027] Therefore, according to the frame material for a structure 11A shown in FIG. 9, the thickness of the cushioning member 11bA can be secured to be relatively large, thereby effectively mitigating the impact when a person, object, etc. comes into contact with the frame material for a structure 11.

[0028] In addition, a preferred modified example of the above-mentioned structure frame material 11A is one in which the exposed surface of the cushioning member 11bA protrudes outward from the visible surface of the structure frame material 11 (the left end surface in Figure 9), and is flush with the visible surface of the structure frame material 11 without protruding from the visible surface. According to this modification, the width of the opening 10a can be made wider, and the occurrence of objects coming into contact with the cushioning member 11bA can be reduced.

[0029] <Third embodiment> A frame material for a structure 11B shown in FIG. 10 is obtained by replacing the above-mentioned frame material main body 11a with a frame material main body 11aB.

[0030] Frame body 11aB is formed so that the lower end of recess 11a23 is located at its lower end. That is, the lower end of cutout portion 11a2 and the lower end of fold-in portion 11a3 both coincide with the lower end of frame body 11aB. Therefore, the lower end of the buffer member 11b, which is fitted into the recess 11a23, also approximately coincides with the lower end of the frame body 11aB.

[0031] Therefore, according to the frame material for structures 11B shown in FIG. 10, the cushioning member 11b extending in the vertical direction can be arranged also at the bottom part of the frame material main body 11a, thereby effectively mitigating the impact when it comes into contact with a person (especially the toes, etc.) or an object, etc.

[0032] <Fourth embodiment> A frame material for a structure 11C shown in FIG. 11 is obtained by replacing the frame material main body 11a of the frame material for a structure 11 with a frame material main body 11aC.

[0033] The frame material main body 11aC is obtained by adding a folded-in portion 11a4 to the frame material main body 11a.

[0034] The folded-in portion 11a4 is formed by folding inward a plate-shaped portion on the visible surface side of the frame material main body 11aC in substantially the same manner as the folded-in portion 11a3.

[0035] The cushioning member 11b having the above-mentioned structure is fitted into a recess 11a23' formed by the notch 11a2 and the two folded-in portions 11a3 and 11a4. The two intersecting outer surfaces of the cushioning member 11b are bonded to the folded-in portions 11a3 and 11a4 by adhesive 11a5.

[0036] Therefore, according to the frame material for a structure 11C shown in FIG. 11, the bonding strength of the cushioning member 11b to the frame material main body 11aC can be improved by the two folded portions 11a3, 11a4, and the cushioning member 11b can be effectively prevented from coming off due to impact or deterioration of the adhesive points. <Fifth embodiment> A structure frame material 11D shown in FIG. 12 is obtained by replacing the frame material main body 11a of the structure frame material 11 with a frame material main body 11aD and replacing the buffer member 11b with a buffer member 11bD.

[0037] The frame material main body 11aD is the same as the above-mentioned structural frame material main body 11a, except that an engaged portion 11a32 is provided at the folded-in portion 11a3. In the illustrated example, the engaged portion 11a32 is a through-hole.

[0038] The cushioning member 11bD is provided with an engaging portion 11b1 that fits into the engaged portion 11a32 of the fold-in portion 11a3 on the surface of the cushioning member 11b that faces the fold-in portion 11a3. The engaging portion 11b1 is formed in an arrow-shaped vertical section with an expanded diameter at the top side, and is elastically contracted and inserted into the engaged portion 11a32, with the upper end portion elastically expanding in diameter on the back side of the folded-in portion 11a3.

[0039] Therefore, according to the frame material for a structure 11D shown in FIG. 12, the joining strength of the cushioning member 11bD to the frame material main body 11aD can be improved, and the cushioning member 11bD can be effectively prevented from coming off due to impact or deterioration of the joint.

[0040] In the structure frame material 11D shown in Fig. 12, the engaged portion 11a32 may be a notch, and the hook-shaped engaging portion 11b1 may be engaged with the notch. Also, the concave-convex relationship between the engaged portion 11a32 and the engaging portion 11b1 may be reversed.

[0041] Sixth embodiment A frame material for a structure 11E shown in Figs. 13 and 14 is obtained by replacing the buffer member 11b in the frame material for a structure 11 with a buffer member 11bE.

[0042] The cushioning member 11bE is obtained by adding protruding parts 11b2, 11b3, and 11b3 that protrude in three directions to the cushioning member 11b.

[0043] One of the protruding parts 11b2 protrudes to one side in the thickness direction of the door body 20 (to the right in Figs. 13 and 14). As shown in Fig. 14, this protruding part 11b2 is inserted into and locked in the cutout part 11a2 of the frame material main body 11a, and contacts the back surface of the plate-shaped part on the visible surface side.

[0044] The other two protrusions 11b3, 11b3 are inserted and engaged into the cutout 11a2 of the frame material main body 11a at the upper and lower ends of the cushioning member 11bE, respectively, and contact the back surface of the plate-shaped portion on the visible surface side (see Figure 13).

[0045] Therefore, according to the frame material for a structure 11E shown in Figures 13 and 14, the joining strength of the cushioning member 11bE to the frame material main body 11a can be improved, and the cushioning member 11bE can be effectively prevented from coming off due to impact or deterioration of the joint.

[0046] In addition, an adhesive (including double-sided tape or adhesive) may be interposed between the protruding portion 11b2 and the back surface of the plate-like portion of the frame body 11a, and between the protruding portion 11b3 and the back surface of the plate-like portion of the frame body 11a, if necessary. This configuration can further improve the bonding strength of the cushioning member 11bE.

[0047] <Other Modifications>

[0048] According to the above embodiment, examples have been given in which the cushioning member protrudes from the surface of the frame material main body (see Figure 9), the lower end of the cushioning member is approximately aligned with the lower end of the frame material main body (see Figure 10), a folded portion 11a4 is added to the projected surface side (see Figure 11), the engaging portion 11b1 of the cushioning member engages with the engaged portion 11a32 of the folded portion 11a3 (see Figure 12), and the cushioning member is engaged with the cutout portion 11a2 (see Figure 14).However, as other examples, these aspects can also be combined as appropriate.

[0049] According to the above embodiment, the cushioning member is provided only on the corner portion of the entrance side or the exit side of the frame body 10 (the lower side on the paper in Figure 2), but as another example, it is also possible to provide the cushioning member in the manner described above on both the entrance side and the exit side of the frame body 10.

[0050] Furthermore, the frame material for the structure may be in a shape other than that shown in the figures, so long as it has a plate-shaped corner portion 11a1, and it may be in the form of a long material, such as a channel steel, Z-shaped steel, angle steel, or square steel tube.

[0051] According to the above embodiment, the frame material for a structure 11 is used as the vertical frame on the door end side, but in a similar manner, the frame material for a structure equipped with the above-mentioned cushioning member can be used as the vertical frame 12 on the central side in the width direction (see Figure 1) or as the upper horizontal frame 14.

[0052] According to the above embodiment, the fitting device 1 is a sliding door that is opened and closed manually, but as another example of this fitting device, it is also possible to use a sliding door that is opened and closed electrically.

[0053] According to the above embodiment, the frame material for structures having the above-mentioned configuration is applied to a suspended sliding door, but as an example other than the illustrated example, this frame material for structures can be applied to a non-suspended sliding door that rolls or slides on a sill, a hinged door (door), a folding door, a sliding door, a window, a shutter device, or other manual or electric fitting device or opening and closing device. Furthermore, the above-mentioned frame material for a structure can also be used simply as a frame material for the inner edge of an opening, such as a gate-shaped frame that does not constitute an openable and closable fixture.

[0054] The structures on which the frame material for structures of the above-mentioned embodiments can be installed include wooden buildings, reinforced concrete buildings, vehicles, ships, airplanes, etc.

[0055] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate without departing from the gist of the present invention.
