Description

  The present invention relates to a chair, a seat chair, and a seat formed by extending a seat between frame materials that face and frame a body-supporting surface that supports the body, such as a waist surface (seat) and a dorsal surface (backrest), It relates to automobile seats, train seats, aircraft seats, theater seats, sofas, benches and the like (hereinafter referred to as “seats”).

As a method of stretching the sheet base between the frame materials, it is assumed that one frame material is configured by meshing the uneven grooves and the uneven grooves of the two ribs having continuous uneven grooves in the length direction, A method in which the edge of the sheet base is sandwiched between the engaging concave and convex grooves and fixed to the frame member (see, for example, Patent Document 1), while a flange extending in the length direction is provided at the edge of the frame member, A hook is attached to the edge of the ground, and the hook is hooked on the flange of the frame member (see, for example, Patent Document 2 and Patent Document 3). A pair of fasteners that mesh with the edge of the belt and the edge of the belt-like border are attached. For example, Patent references 4) is known.
Japanese Patent Laying-Open No. 2001-8774 (FIG. 3) Japanese Patent Laying-Open No. 2003-9996 (FIG. 2) Japanese Patent Laid-Open No. 10-327972 (FIG. 2) Japanese Unexamined Patent Publication No. 2003-10009 (FIGS. 2 and 4)

  The conventionally known method is generally that the sheet is stretched by stretching and the edge of the stretched sheet is hooked on the frame material. It is difficult to apply. However, seats that are easy to stretch are depressed when the body is placed on them, the body sinks, the posture becomes unstable and it is easy to get tired, and it is often used for seats of automobiles and trains that are used for a long time. It is unsuitable.

  However, in Patent Document 3 above, the frame material is assembled so that the two angles (L-shaped steel) face each other to form a “gate” -shaped cross-sectional shape, A pipe is interposed between the vertical surfaces, the pipe is welded and fixed to the vertical surface of one angle, and the pipe is screwed and fixed to the vertical surface of the other angle. The edge of the sheet is hooked to the edge of the (flange) and temporarily fixed, and the screw is pulled to pull the sheet. However, in that method, when the screw is tightened, the entire angle rotates around the axis of the pipe and pulls the sheet material, so the rotational moment caused by the tensile strength of the entire sheet material acts on the screw and angle. To do. For this reason, thick and strong screws that do not bend even when a rotational moment acts on them and angles with a large cross-sectional secondary coefficient are used. It becomes difficult to finish.

  The present invention is composed of a sheet material that is strong and difficult to stretch, in particular, a cocoon-like elastic yarn having an elastic recovery rate of 90% or more after elongation of 15% and a single yarn fineness of 300 dtex or more. In a direction in which the axis of the yarn is continuous, stretch the elastic fabric that is not easily stretched with a tensile stress of 150 N / 5 cm or more when stretched to 10%, and stretch it between the frame materials of the seat frame. The purpose is to finish the joint between the seat and frame material beautifully and compactly.

In the seat according to the present invention, (a) a seat base 12 constituting a body receiving surface that supports the body is stretched between a pair of frame members 11a and 11b facing each other and rimming the seat, (b) Each frame member 11 has a plurality of screw insertion holes 13 penetrating in a direction in which the pair of frame members face each other with a predetermined interval in the continuous length direction of the frame member 11, (C)
A saddle-shaped support member 15 having a plurality of screw holes 14 drilled at the same interval as the screw insertion holes 13 of the frame member is attached to the edge 28 of the sheet base, and (d) the frame member The tip of the screw 16 inserted into the screw insertion hole 13 is screwed into the screw hole 14 of the hook-shaped support member. (E) The edge 16 of the sheet base is framed together with the hook-shaped support member 15 by the screw 16. The first feature is that the sheet material 12 is drawn toward the material 11 and fixed to the frame material 11, and (f) the sheet base 12 is tensioned between the pair of frame materials 11a and 11b facing each other. .

  In addition to the first feature, the second feature of the seat according to the present invention is that (g) the end edge 18 on one side of the strip-shaped border 17 that continues long in the direction in which the end edge 28 of the seat base continues is a saddle-shaped support. (H) the strip edge 17 is folded along the direction in which the edge 18 continues to wrap the frame material 11; (I) On the back surface of the sheet material 12 where the other edge 19 on the other side of the folded strip-shaped border 17 is the back side of the edge 18 attached to the sheet material 12, the frame material 11 It is in the point which is latched directly or indirectly through the seat base 12.

  The third feature of the seat according to the present invention is that, in addition to the second feature, (j) the frame member 11, the saddle-shaped support member 15, and the edge 28 of the seat base push the edge 28 of the seat base. The padding material 21 having a U-shaped cross-sectional shape is formed and is fitted in the pressing groove 20 and is wrapped in the U-shape by the padding material 21, and (k) the sheet base 12 is , Projecting from one frame member (11) of the pair of frame members 11a and 11b facing each other from the pushing groove 20 toward the other frame member (11), and (l) a belt-like border 17 The padding material 21 is wrapped together with the material 11 in a U-shape.

  The seat according to the fourth aspect of the present invention is characterized in that, in addition to the third feature, (m) the padding member 21 is fixed to the frame member 11, and (n) the shaft core is a pair of frame members 11a. -A through hole 27 is formed in the padding material 21 so as to continue straight in the direction in which 11b faces and pass through the screw insertion hole 13 of the frame material 11.

  The fifth feature of the seat according to the present invention is that, in addition to any of the first, second, third and fourth features, (o) the edge 28 of the seat base is folded back to be double. (P) the folded back margin 22 and the sheet base body 23 are stitched together, and (q) a tunnel 24 extending along the folded end edge 28 of the seat base is formed by the folded margin 22. (R) The saddle-shaped support member 15 is inserted into the tunnel 24 and attached to the edge 28 of the sheet material.

  The sixth feature of the seat according to the present invention is that, in addition to any of the first, second, third, fourth, and fifth features, (s) the edge 18 on one side of the strip-shaped border 17 is provided. The edge (28) or the frame member 11 of the sheet base on the other side which is the back side with respect to the one side to which it is attached, and the remaining other of the band-shaped border 17 which is not attached to the sheet base and is free. Locking members 25 and 26 that engage with each other are attached to the edge 19 on one side, and (t) the edge of the belt-like border 17 that is folded back and encloses the frame material in a U-shape. 19 is connected to the frame member 11 directly or indirectly via the sheet base 12 via the locking members 25 and 26.

  In the present invention, when the screw 16 is turned, the edge 28 of the sheet base is pulled to the frame member 11 together with the hook-shaped support member 15 so as to be picked up by the screw, so that it is screwed into the screw hole 14 of the hook-shaped support member. When all the screws 16 are sequentially turned, the sheet base 12 is tensioned between the frame members 11a and 11b. The tip of the screw 16 protrudes from the screw insertion hole 13 of the frame member 11 and is directed in a direction in which the pair of frame members 11a and 11b face each other. Acting in the length direction (axial direction), the rotational moment due to the tensile strength does not act on the screw 16. Therefore, the screw 16 can be used even if it is thin and easily bent. The edge 28 of the sheet base is pulled to the frame member 11 by picking and pulling it with the screw 16, and at this time, the saddle-shaped support member 15 merely moves the edge 28 of the sheet base so that the screw 16 is not removed. It only reinforces it. For this reason, the saddle-shaped support member 15 may be as thin and flexible as the sheet base, and it does not require a particularly large cross-sectional secondary coefficient or hard and strong rigidity. Then, the saddle-shaped support member 15 is attracted and brought into close contact with the frame member 11, and is integrated with the frame member 11. Therefore, according to the present invention, a thin flat plate is used for the saddle-shaped support member 15 and a thin screw is used for the screw 16, so that the joint portion between the sheet base 12 and the frame member 11 can be compactly finished. , You can get a seat with a good overall aesthetic, without the peripheral edge becoming particularly thick.

  In this way, a thin and flexible flat plate can be used for the bowl-shaped support member 15, and if it is brought into close contact with the frame member 11 with the screw 16, it deforms according to the shape of the frame member 11. It is not necessary to form it in the same shape as the frame member 11 in advance, and the cost of the members constituting the seat can be reduced. Further, since a thin flexible flat plate can be used for the bowl-shaped support member 15, in order to join the edge 28 of the sheet base to the frame member 11, the dimension between the frame members 11a and 11b facing each other ( Distance) and several temporary fixing screws corresponding to the dimensional difference between the sheet material 12 stretched between them (distance) and a saddle-shaped support. Temporarily screwing into a part of the screw hole 14 of the material, and by turning them alternately and repeatedly, gradually draw a part of the bowl-shaped support material (the edge 28 of the sheet base) to the frame material 11, A predetermined screw 16 is screwed into the remaining screw hole 14 of the hook-shaped support member, and the entire hook-shaped support member 15 is closely fixed to the frame member 11, and then the previously used temporary fixing screw is replaced with the predetermined screw 16. The seat can be assembled without the need for special equipment to assemble the seat. Even door area 12 sufficiently tense and can be stretched. In addition, a long screw is not required to join the edge 28 of the sheet base to the frame member 11, and the distance between the frame members 11a and 11b and the size difference between the sheet bases are shorter, and the saddle-shaped support member 15 The sheet base 12 can be tensioned sufficiently with a screw 16 having a thickness of about 10 mm, and the edge 28 of the sheet base is protruded by a screw tip protruding from the frame member 11 or the saddle-shaped support member 15. Problems such as injury by touching the protruding screw tip are avoided. Then, by partially changing the dimensional difference between the distance between the frame members 11a and 11b and the width of the sheet base 12, it is possible to easily stretch the sheet base 12 while partially changing the degree of tension. Become.

  A joint portion between the sheet base 12 and the frame member 11 is wrapped in a belt-like border 17 and decorated. Since the edge 19 that is directly or indirectly locked to the frame member 11 is a free end protruding from the sheet base 12, the belt-like border 17 is expanded or contracted in accordance with the expansion / contraction change of the sheet base 12 caused by the weight. Therefore, the edge 19 is not detached from the frame material 11 and the belt-like border 17 is not wrinkled, and the periphery of the seat is bordered by the belt-like border 17 and the finish is beautiful. In particular, when the frame material 11 is wrapped with the padding material 21, the belt-like border 17 is pushed up by the padding material 21 and swells, and the belt-like border 17 does not cause wrinkles or slack. However, the skin does not get injured by touching the frame member 11, and a comfortable seat can be obtained.

  When the padding material 21 is formed into a U-shaped cross-sectional shape in which a pressing groove 20 capable of pressing the edge 28 of the sheet is formed, the band-shaped border 17 is free so as to be accommodated in the pressing groove 20. If the locking member 25 that locks the edge 19 is attached to the edge 28 of the sheet material or the frame material 11, the pair of locking members 25 and 26 that engage with each other are sandwiched between the padding material 21 in the push groove 20. Therefore, it is not necessary to use a locking member with a particularly strong engagement force, and the edge of the sheet is simply pushed into the pressing groove 20 by pushing the locking member 26 attached to the free edge 19 of the belt-shaped edge 17. The padding material 21 can be easily covered with the belt-shaped border 17 by positively engaging with the locking member 25 attached to 28 or the frame material 11. In the present invention, the “U-shaped cross-sectional shape” of the padding material means that a depression groove 20 is formed in a part of the padding material, and both sides of the depression groove 20 sandwiching the depression groove 20 face the U-shape. The protruding cross-sectional shape is meant.

  The padding material 21 can be attached so as to wrap the frame material 11 and the saddle-shaped support material 15 after the sheet material is stretched on the frame material 11, but is fixed to the frame material 11 in advance and integrated, and then screwed into the frame material 11. If the through-hole 27 following the insertion hole 13 is formed, the padding material 21 does not prevent the sheet material from being stretched on the frame material 11, and a positional shift occurs between the padding material 21 and the frame material 11. The seat is beautifully finished.

  The tunnel 24 for inserting the saddle-shaped support member 15 and attaching it to the edge 28 of the sheet base is formed at the folding back margin 22 of the sheet base and can be freely deformed. 15 is not necessary, and a thin flexible flat plate can be used for the saddle-shaped support member 15, so that the shape (contour) of the edge 28 is the shape of the saddle-shaped support member 15 or the frame material 11. It is not necessary to prepare the sheet material 12 according to the above, and the sheet material can be stretched between the frame members by partially changing the degree of tension according to the difference in the outline and shape.

  As described above, according to the present invention, the seat frame is stretched between the frame materials of the seat frame without using a special device even in the case of a sheet material that is difficult to stretch, and the joint between the sheet material and the frame material is made compact, and the feel is good and beautiful. A seat can be obtained simply, efficiently and economically.

  The sheet base 12 is woven or knitted using a cocoon-like elastic yarn having an elongation of 15% and an elastic recovery rate of 90% or more and a single yarn fineness of 300 dtex or more. It is preferable to use an elastic fabric that is not easily stretched and has a tensile stress of 150 N / 5 cm or more when stretched to 10% in the direction in which the shaft core continues. The elastic yarn as the main material of the elastic fabric includes a polyether ester elastic yarn, preferably a polyether ester as a core component polymer, and a heat-melting polymer having a lower melting point as a sheath component polymer. It is preferable to use a heat-fusible core-sheath composite polyether-based ester elastic yarn (for example, Toyobo Co., Ltd., product name: Diaflora).

  FIG. 1 illustrates a seat in which the seat base 12 is tensioned between the frame members 11a and 11b facing left and right, but the seat base 12 is tensioned between the frame member and the frame member facing up and down or front and rear, that is, the longitudinal direction of the seat. In addition, a sheet fabric woven or knitted so that the axis of the elastic yarn is continuous in either one of the left and right or front and rear directions includes a direction in which the axis of the elastic yarn is not continuous. It can also be stretched on the seat by tensioning in all directions, that is, in the left / right and front / rear directions. 1 is continuous over the entire length of the frame member 11, a plurality of short hook-shaped support members can be intermittently attached to the frame member 11.

  The saddle-shaped support member 15 is preferably made of a saddle member such as a metal narrow plate or a round bar, but it may be made of plastic, and its cross-sectional shape is hollow, U-shaped, I It may be a shape or an H shape. The screw hole 14 of the hook-shaped support member 15 may be formed by attaching a nut to the hook-shaped support member 15. The frame member 11 shown in FIGS. 1 and 2 has a flat plate shape, but the cross-sectional shape thereof is not limited, and the rounded cross-section of the swelled padding material 21 shown in FIG. It can also be made into a hollow cross-sectional shape in which a large number of cavities are formed so as to form a honeycomb structure, and the frame material (11) having the hollow cross-sectional shape is extruded by aluminum or plastic Alternatively, several types of members having a curved cross-sectional shape can be assembled and formed. For the padding material 21, a porous material such as a thick fiber web (nonwoven fabric, resin-impregnated cotton) or a plastic foam in which fibers are bonded is used. In the case where the frame material (11) is inflated and has a rounded hollow cross-sectional shape, the padding material (21) may be thin enough that the frame material (11) covers the outer surface lightly. Alternatively, the bolt attached to the saddle-shaped support member 15 may be tightened from the outside of the frame member 11 with a nut.

  As shown in FIG. 2, when the padding material 21 has a U-shaped cross-sectional shape that encloses the frame material 11, the edge 28 of the sheet can be drawn into the recessed pressing groove 20 by the screw 16. The free edge 19 of the belt-like border and the locking members 25 and 26 can be stored in the push groove 20 so as not to be exposed to the outside, and the seat is finished beautifully. The padding material 21 that swells to form a U-shaped cross-section can be formed by combining a plurality of angular porous materials so as to surround the frame material (11) in a U-shape, and the angular porous The material is rounded by being fastened to a belt-like border 17 that encloses the material.

  A hook-and-loop fastener, a slide fastener, a hook, a hook, or the like is used for the locking members 25 and 26. As shown in FIG. 2, the belt-like hooks (25, 26) formed of plastic and having an edge having a J or U-shaped cross section as shown in FIG. Are attached to the free edge 19 by sewing. The belt-like border 17 is made of woven fabric, knitted fabric, non-woven fabric, artificial leather, synthetic leather, natural leather, or the like. The end edge 18 of the belt-like border 17 attached to the sheet base 12 may be sewn to the sheet base body 23 together with the folding margin 22 and the locking member 25 that constitute the tunnel 24. As shown in FIG. 2, the locking member 26 attached to the free edge 19 of the belt-like border is attached to the inside of the belt-like border that touches the padding material 21, and is exposed from the gap of the push groove 20.
