Description

  The present invention relates to a chair and a seat or a back constituting the chair, and in particular, has a feature in a means for attaching a skin material covering a cushion.

  In a chair, if the seat is configured with a cushion on the seat plate or the back is configured with a cushion on the back plate, the cushion is covered with a skin material made of woven fabric or knitted fabric, etc. The edge of the material is attached to the seat plate or back plate. And as a method of attaching the skin material to the seat plate or the back plate, a belt-like locking member (edge material) is fixed to the peripheral portion of the skin material, while an attachment groove with an outward opening is formed in the seat plate or the back plate. In addition, there is a method of fitting the locking member into the mounting groove.

Thus, in the method of fitting the locking member into the mounting groove, the locking member is inserted into the mounting groove by crossing the insertion / removal direction of the locking member and the pulling direction when tension is applied to the skin material. Is held in the state. However, in a configuration in which the locking member is simply inserted into the mounting groove, it may not be possible to reliably prevent the locking member from coming out of the mounting groove.

  Therefore, in Patent Document 1, in a configuration in which a mounting groove is provided in a resin backboard (back plate) and a hook (locking member) is inserted into the mounting groove, a portion close to the opening edge and the hook on the inner surface of the mounting groove are mutually connected. It is disclosed to provide a pair of claws that are engaged to prevent the hook from coming off. The mounting groove is formed by projecting inwardly a protrusion having a U-shaped cross section on the backboard.

JP 2006-183236 A

In Patent Literature 1, when tension is applied to the skin material, the hook tends to rotate around the claw, but the end opposite to the claw is in contact with the inner surface of the attachment groove, so the hook is attached to the attachment groove. It is located inside and is held so that it cannot be removed. Therefore, in order to prevent the hook from coming off more accurately, the depth of the mounting groove is preferably as deep as possible. However, if the depth of the mounting groove is increased, the height of the ridge increases, which may increase the amount of resin used and increase the cost. Moreover, it cannot be denied that the mold becomes complicated in order to form the ridges and claws, and there is a concern about an increase in cost in this aspect.

  Further, although Patent Document 1 is applied to a vehicle seat, when applied to a seat or back of a non-vehicle chair such as an office rotary chair, the seat and back cushion of these chairs are compared to those for a vehicle. Since it is thin, the presence of the protrusion may be transmitted to the seated person via the cushion, and there is a possibility that the seated person may feel uncomfortable.

  The present invention has been made to improve the current situation.

The invention according to claim 1 relates to a seat or a back, and this invention covers a cushion disposed on the seat plate or the back plate with a skin material, and attaches at least a part of the skin material to an edge of the skin material. In the configuration that is locked to the back of the seat plate or back plate via a locking member,
While the seat plate or the back plate has a locking hole for attaching the locking member, the locking member is inserted into the locking hole and comes into contact with one inner surface of the locking hole. A fitting portion, and a flange portion facing the other inner surface of the engagement hole facing the one inner surface is provided on the fitting portion, and the flange portion is attached to the seat plate or The locking plate is brought into contact with the back plate from the inside, and the angle of the other inner surface is different from the one inner surface so that the groove width increases toward the back.

  The invention of claim 2 embodies claim 1, and in this invention, the locking member is an L-shaped fitting portion having a base plate overlapping the outer surface of the seat plate or the back plate, and the flange portion. And has a crank shape as a whole. The invention of claim 3 embodies the invention of claim 1 or 2. In this invention, the fitting portion is elastically deformed when the fitting portion is inserted into and removed from the locking hole. A stopper part is provided that returns and deforms by elastic restoring force when inserted completely.

The present invention also includes a chair. That is, this chair has a body support member that is a superordinate concept of claims 1 to 3, and this body support member has a locking hole for attaching the locking member to the substrate, the locking member is inserted into the locking hole has a fitting portion which abuts on one of the inner surface of the locking hole, the fitting portion, the one of the inner surface of the locking hole A flange part facing the inner surface of the other side is provided, the flange part is in contact with the substrate from the inside, and the locking hole has a groove width that increases toward the back. The angle of the other inner surface is different from the one inner surface.
The body support member here includes a wide range of members having a cushion and a skin material such as an elbow rest, a headrest, and a shoulder rest in addition to a seat and a back.

In the first aspect of the invention, when tension is applied to the skin material and the locking member is pulled outside the seat plate or the back plate, the collar portion of the locking member comes into contact with the other inner surface of the locking hole. The locking member is held so that it cannot be removed from the locking hole.

And this invention does not need to provide a protrusion like patent document 1 in a seat board or a back board, and it is sufficient if a seat board or a back board provides a locking hole with the same thickness as before. For this reason, when the seat plate or the back plate is made of resin, it is possible to prevent an increase in the amount of the resin used and the complexity of the mold, thereby avoiding an increase in cost. Moreover, since it is not necessary to provide a protrusion like patent document 1, a discomfort is not given to a seated person's body. Moreover, since the groove | channel width is widened so that the locking hole goes to the back, the fitting of a fitting part is invited.
The invention according to claim 4 also exhibits the same effect as that of the invention according to claim 1.

When the locking member is in a crank-like form as in claim 2, the collar portion comes into contact with the seat plate or the back plate from the inside while the substrate is in close contact with the back surface of the seat plate or the back plate. It can be securely held in a state where it cannot be displaced. Further, not only the stopper portion provided with retaining the ability to elastically deform as claimed in claim 3 is further improved, in order to insert the fitting portion into the locking hole, insert the fitting portion into engagement hole Since it is possible to give a click to the person when it is fully cut, there is an advantage that the person can grasp with a sense (tactile sense or hearing) that the locking member is attached in a predetermined state.

Next, an embodiment of the present invention will be described with reference to the drawings. This embodiment is applied to a rotary rocking chair that is frequently used for office work. In the present application, but using the wording such as "longitudinal", "lateral" to identify the direction, which is the usual reference seated occupant orientation posture. Front view is seen from a seated occupant and opposed direction.

(1). Outline of Chair First, an outline of the chair will be described with reference mainly to FIG. 1 and FIG. As shown in FIG. 1, the chair includes a leg 1, a seat 2, and a backrest 3 as major elements. Although the leg 1 has branch legs extending in the radial direction, the illustration is omitted, and only the leg support 4 made of a gas cylinder is shown. A base 5 is fixed to the upper end of the leg column 4, and a seat 2 is disposed above the base 5.

As shown in FIG. 2, the seat 2 is made of resin seat plate has a (seat inner shell) 6 and the seat cushion 7 strung on its upper surface, the seat receiving member 8 shown in FIGS. 2 and 3, It is installed so that the front-rear position can be adjusted. The seat receiver 8 is made of resin, and its front part is connected to the front part of the base 5 via the front link 9. The front link 9 is connected to both the base 5 and the seat receiver 8 in a side view. Rotate relative to it. Therefore, when the front link 9 rotates, the seat receiving body 8 and the seat 2 move back and forth while moving up and down. The seat receiver 8 can also be called an intermediate support or a seat outer shell.

The backrest 3, the shell-like backplates body pressure of a seated person such as (back inner shell) 10, has a this attached shell shaped back support (back outer shell) 11, the back plate 10 A back cushion 12 is stretched on the front surface. The back cushion 12 is covered with a skin material 13 such as a cloth from the front.

The lower end of the back support 11 has a forward extending pair of arms 14 are formed integrally with the left and right arms 14 are connected to the base 5 so as to tilted backward around the front end portion thereof, and the left and right arms 14 is connected to a rear portion of the seat receiving body 8 via a bracket 15 (which is slightly exposed in FIG. 1 (B).). For this reason, when the backrest 3 is tilted backward, the seat receiver 8 and the seat 2 are pulled by the metal fitting 15 and are raised while moving backward. At the rear of the base 5, the elastic member for imparting a resistance (not shown) is built against the locking. A lever device 16 (see FIG. 2) for holding the seat 2 in a desired front-rear position is mounted on the lower surface of the right side portion of the seat plate 6.

(2). Structure of Seat Plate Next, the structure of the seat 2 and the seat support 8 and the relationship between them will be described. First, the seat plate 6 will be described. For example, as can be understood from FIGS. 3 to 5, the seat plate 6 includes an intermediate portion 17 to which the body pressure of the seated person is strong, a front side portion 18 positioned in front of the intermediate portion 17, and a rear portion 19 positioned behind the intermediate portion 17. And side portions 20 located on the left and right outer sides of the intermediate portion 17 and the front portion 18.

Longitudinal center slit 21 back and forth in the lateral middle portion of the intermediate portion 17 are plural rows formed, the right and left sides of the intermediate portion 17, the front and rear longitudinal side slits 22 are plural rows formed. Between the group of the center slits 21 and the group of the side slits 22, a group of a plurality of middle slits 23 that are gently inclined so as to fall down toward the longitudinal center line of the seat plate 6 is formed. The middle slit 23 is gently curved. Due to the presence of these groups of slits 21, 22 and 23, the intermediate portion 17 extends and deforms downward in proportion to the body pressure of the seated person.

For example, as shown in FIG. 5, the front portion 18 of the seat plate 6 includes a front bottom plate 24 in a state of Chi paragraph from the intermediate portion 17 is constituted by the vertical and horizontal front rib 25 projecting from the upper surface thereof, the ribs The upper surfaces of the 25 groups are continuous with the upper surface of the intermediate portion 17 in the same plane. Therefore, the front portion 17, a number of prismatic space partitioned by the group of the ribs 25 is open upward. In addition, the front end of the front portion 18 is configured with a bowl-shaped front wall 26 that is gently curved in a forward convex shape in order to soften the contact with the thigh of the seated person.

For example as shown in Figure 5, the rear 19 of the seat plate 6 is adapted to the rigid structure projecting from a group of vertical and horizontal behind rib 28 behind the bottom plate 27, basically even if a body pressure of a seated person elasticity Does not deform. And the intermediate part 17 and the rear part 19 are parted by the long slot hole 29 of the up-and-down opening extended in the left-right direction. Therefore, the intermediate portion 17 can be extended and deformed without being restricted by the rear portion 19, and the expansion and deformation of the intermediate portion 17 does not reach the rear portion 19.

The rear bottom plate 27 has a shape in which the horizontal posture portion is continuous in two stages so that the front side is low and the rear side is high, while the rear rib 28 has a front end at the same height as the intermediate portion 17. Yes, it is inclined while curving in side view so that it gradually increases as it goes backward. This is a measure to fit the curve of a person's buttocks. The rear end of the rear portion 19 is constituted by an upward rear bank portion 30.

As shown in FIG. 5, the side portion 20 has a side bottom plate 32 and a side wall 33 rising upward from the side end thereof. The side bottom plate 32 and the side wall 33 are also formed by side ribs 34 having a triangular shape in front view. It is connected. Side portion 20 also has a rigid structure that does not elastically deform the body pressure of a seated person.

The seat cushion 7 is a molded product manufactured (foamed) using a mold, and as shown in FIG. 8, a portion where the left and right side surfaces and the upper surface are connected has a sharp shape with an acute angle. The front portion of the seat cushion 7 is provided with three front projections 35 located on the left and right intermediate portions and the left and right sides of the seat cushion 7. The front projections 35 are provided on the front portion of the seat plate 6. It is fitted in the recess 36. Thereby, the seat cushion 7 is positioned accurately. As shown in FIG. 4, an auxiliary rib 37 that supports the front protrusion 35 is provided in the front recess 36 of the seat plate 6. Further, (see FIG. 8 (A) also), as shown in FIG. 5, the outside of the side ribs 23 is provided with a front and rear longitudinal upward opening groove 38. The presence of the upward opening groove 38 allows the intermediate portion 17 of the seat plate 6 to be extended and deformed.

As shown in FIGS. 4 and 7, the rear portion of the seat cushion 7 is provided with a laterally long rear projection 35 ′ that abuts against the upper surface of the group of ribs 28 constituting the rear portion 19 of the seat plate 6. The rear projection 35 ′ does not hit about ¼ of the front side of the rear portion 19 of the seat plate 6. For this reason, when the intermediate portion 17 of the seat plate 6 sinks and deforms, the seat cushion 7 is smoothly deformed with a small curvature.

Further, as shown in FIG. 7A, on the front side of the rear bank 30 in the rear edge of the seat plate 6, a long rear long groove 36a is formed on the left and right by lowering the rib 28, A rear protrusion 35a that fits in the rear long groove 36a is formed at the rear end edge of the seat cushion 7. Furthermore, the front of the rear long groove 36a of the seat plate 6, while the thus auxiliary protrusions 36b to slightly increase the rib 28 to the right and left intermediate portions and the left and right outside is formed, the seat cushion 7, auxiliary An auxiliary recess 35b that fits into the protrusion 36b is formed.

The rear portion of the seat cushion 7 is held on the seat plate 6 so as not to be displaced by the fitting of the rear long groove 36a and the rear protrusion 35a and the fitting of the auxiliary protrusion 36b and the auxiliary recess 35b . For this reason, there is no trouble that the rear part of the seat cushion 7 moves by being seated, and a comfortable sitting comfort can be obtained.

(3) .Surface material mounting method
As shown in FIGS. 7B and 8, the seat cushion 7 is covered from above with a skin material 39 made of woven fabric or knitted fabric, and the periphery of the skin material 39 is placed on the periphery of the seat plate 6 from below ( It is fixed (from the back side). This point will be described next. In the present embodiment, the left and right side edges and the rear edge of the skin material 39 are attached to the seat plate 6 using the clip 40 shown in FIG. 8, and the invention of the present application is used to attach the front edge of the skin material 39. The left and right horizontally long locking tool 41 shown in FIG. 6 is used for attaching the front edge.

Clip 40 shown in FIG. 8 has a substrate 42 which is fixed to the edge of the skin material 39, the substrate 42, a back plate 43 extending along the side edges of the skin material 39, both side ends of the back plate 43 A pair of side plates 44 connected to each other are projected upward. The back plate 42 and the side plate 44 converge on the top portion 45, and the catch piece 46 projects downward from the top portion 45. Since only the upper end of the catch piece 46 is connected to the top portion 45, the catch piece 46 is elastically deformed so as to approach the back plate 44. A claw portion 46 a having an engagement surface facing the free end side of the catch piece 46 is formed in the upper and lower halfway portion of the outer surface of the catch piece 46. The back plate 43 and the catch piece 46 form a substantially mountain shape (tapered shape).

The left and right side edges and rear edge of the seat plate 6, and a clip receiving holes 48 which can insert the majority of the clip 40 is formed, the inner edge of the clip receiving hole 48, the claw portion 46a of the clip 40 from the inside Get caught. Thereby, the edge of the skin material 39 is held by the seat plate 6. Subtracting the side of the back plate 44 against the finger tip (or the tip of a tool such as a screwdriver) to the tip of the catch piece 46 deforms collapse the catch piece 46, the engagement between the clip receiving hole 48 is released .

  Further, as shown in FIG. 8A, an inclined surface 48 a that is inclined toward the inner side of the seat plate 6 is formed at the opening edge of the clip receiving hole 48 where the catch piece 46 overlaps. For this reason, it is possible to easily hook the fingertip or tool to the tip of the catch piece 46.

As clearly shown in FIG. 6, three clip receiving holes 48 are formed on each of the left and right side edges and the rear end edge of the seat plate 6. An edge plate 49 such as a resin plate may be fixed to the edge of the skin material 39 as indicated by a one-dot chain line in FIG. When the edge plate 49 is used in this manner, the skin material 39 is retained, so that the skin material 39 can be held in a stretched state without slack or wrinkles even when the clip 40 is mounted in a jumping manner. There is. Edge plate 49 may be fixed to either the front and back of the skin material 39. The seat cushion 7 has a recess into which the clip 40 is fitted.

When the edge plate 49 is fixed to the peripheral edge portion of the skin material 39, since the skin material 39 is made of a flat cloth, it is troublesome to sew the skin material 39 to the skin material 39 in an annular state ( That is, sewing is troublesome.) Measures in this regard, are partially displayed in Fig. That is, in FIG. 6, the edge plate 49 is partially shown by parallel diagonal lines in the upper right part, and the tape 49 'made of a stretchable material such as rubber is shown by hatching, and the corner part is sandwiched between them. The edge plate 49 is connected by an elastic tape 49 '.

As a specific manufacturing method, for example, the edge plate 49 is sewn on the four circumferences of the skin material 39, and then the stretchable tape 49 'is fixed to the adjacent edge plate 49 across the corner portion by sewing or the like. It is possible. Alternatively, when the edge plate 49 is sewn to the skin material 39, it is also possible to sew to the adjacent edge plate 49 with the stretchable tape 49 'stretched. When stretching and stretching the stretchable tape 49 ′, the stretchable tape 49 ′ may be sewn to the skin material 39.

  In any case, since the strong edge plate 49 only needs to be sewn to a portion excluding the corner portion, the attaching operation of the edge plate 49 is very simple, and the adjacent edge plates 49 are elastic. Since it is pulled by the tape 49 ', the skin material 39 is held in a stretched state at the corner. In this regard, it can be an independent invention.

Next, the locking tool 41 will be described based on FIG. 6 and FIGS. 7B and 7C ( the locking tool 41 is omitted in FIG. 7A). Fastener 41 is made of a resin (or a metal plate), have a substrate 51 which surface material 39 is fixed by sewn or the like, outside the two longitudinal side skin material 39 of the edge of the substrate 51 A fitting portion 53 that fits into a horizontally long locking hole 52 provided in the front wall 26 of the seat plate 6 is integrally provided on the long side edge located at the front side.

Three locking holes 52 are provided along the left-right direction, and therefore three fitting portions 53 are also provided. The fitting portion 53 has an upright portion 53a that rises from the substrate 51 , and a flange portion 53b that protrudes from the tip of the fitting portion 53 to the opposite side of the substrate 51, and has an L shape in side view. Therefore, the locking tool 41 has a crank shape in a side view.

The locking tool 41 is pulled to the front side by the skin material 39, and the upright portion 53 a of the fitting portion 53 overlaps the front inner side surface (one inner surface) of the locking hole 52. The tool 41 is held so that it cannot be displaced forward . And, in a state where the substrate 51 is overlapped with the lower surface of the front wall 26, the tip of the flange portion 53b in the fitting portion 53 is in contact with the front wall 26 from above (from the inside where the seat cushion 7 is provided). The fitting portion 53 is held so that it cannot be removed from the locking hole 52. Therefore, the locking tool 41 is held so as not to fall off the seat plate 6 simply by fitting the fitting portion 53 into the locking hole 53.

The front wall 26 of the seat plate 6 is inclined in a side view so that the tip thereof is down, while the rear inner surface (the other inner surface) 52a of the locking hole 52 is in a substantially vertical posture. Therefore, the rear inner surface 52a of the locking hole 52 is inclined in a side view with respect to the front inner surface, and as a result, the groove width of the locking hole 52 increases toward the back (up). For this reason, fitting of the fitting part 52 is invited.

When the rear inner surface 52 a of the locking hole 52 is inclined as in the present embodiment , the flange portion 53 b of the fitting portion 53 may be brought into contact with the rear inner surface 52 a of the locking hole 52. Conversely, it is also possible to overlap over a wide range hook portion 53a on the upper surface of the front wall 26. Anyway, the front wall 26 of the seat plate 6 need only open the locking hole 52, the front wall 26 it is sufficient conventional similar thickness, increasing the amount of the resin or the seated person thigh I don't feel uncomfortable.

At both left and right ends of each fitting portion 53, stopper portions 54 are provided that bulge outside the corner portion where the standing portion 53a and the flange portion 53b are connected. The stopper portion 54 is separated from the fitting portion 53 by a long hole-like slit 55, and therefore the bulging portion 54 can be elastically deformed. The stopper portion 54 is connected to the root of the standing portion 53a and the tip of the flange portion 53b in the fitting portion 53, but may be connected to only one of them. Further, the stopper portion 54, it is also possible to provide the right and left middle portion of the fitting portion 53, and the stopper portion may be a simple protrusion.

Since the stopper portion 54 comes into contact with the upper end of the front inner surface of the locking hole 52 in the mounted state of the locking device 41, the function of preventing the fitting portion 53 from coming off can be improved. Further, when the locking tool 41 is mounted, if the bulging portion 54 is elastically deformed and then passes through the locking hole 53, the bulging portion 54 instantaneously returns and deforms due to elastic restoring force. Since a person can grasp a click feeling, it can be grasped by touching that it is correctly worn.

  Although the locking device 41 can be provided individually corresponding to each locking hole 43, a single locking device 41 extending in a series along the front edge of the seat plate 6 as in the present embodiment. When used, there is an advantage that the mounting operation can be performed quickly. It is also possible to use the locking tool 41 for attaching other parts of the skin material 39 other than the front edge.

In the present embodiment, the skin material 39 is attached by the procedure of first attaching the locking tool 41 to the front end of the seat plate 6 and then attaching the group of clips 40 to the seat plate 6. Each group of clips 40 may be attached in any order.

Although it is possible to attach the four circumferences of the skin material 39 to the seat plate 6 with the locking tools 41, in this case, the locking tools 41 located on the two side edges of the four rotations greatly deform the seat cushion 7 By doing so, the skin material 39 must be attached in a state of being pulled strongly, which may cause troublesome attachment. On the other hand , when the locking tool 41 and the clip 40 are used together as in this embodiment , the locking tool 41 and the clip 40 can be attached to the seat plate 6 without applying a strong tension to the skin material 39. The work of attaching the skin material 39 (assembly of the seat 2) can be performed easily.

(4). Intermediate member and seat plate mounting structure
As shown in FIG. 2, the intermediate member 8 has a structure in which a number of reinforcing ribs 56 are formed vertically and horizontally on the upper surface of the bottom plate, and a hook portion 57 into which the front link 9 is fitted protrudes downward at the front end. doing. In this embodiment , the seat 2 is attached to the intermediate member 8 so that the front-rear position can be adjusted. In FIG. 7A, the seat 2 is displayed in the most retracted state.

As shown in FIG. 3 and FIG. 8 (A), the upper and lower longitudinal rails 58 project downward from the inner edge of the side portion 20 on the lower surface of the seat plate 6, while the left and right side portions of the intermediate member 8. Are integrally formed with a lower rail 59 on which the upper rail 58 is slidably mounted. In this case, as shown in FIG. 8 (A), the inner portion of the upper rail 58, and projecting guide ribs 58a located on the inner side of the lower rail 59 downwardly, thus, the seat plate 6 intermediate member 8 In contrast, it is held so that it cannot be shifted left and right.

The seat plate 6 must be held by the intermediate member 8 so as not to move upward. Therefore, in the present embodiment, the guide claw 60 having a front view shape is provided on the outer edge of the intermediate member 8 from the lower rail 59, while the guide claw 60 is fitted to the left and right sides of the seat plate 6. A stop groove 61 is formed. The retaining groove 61 has a bottom plate 61a, and the guide plate 60 is positioned on the bottom plate 61a, so that the seat plate 6 is held so as not to be detached.

For example, as shown in FIG. 6A, the rear end of the bottom plate 61a in the retaining groove 61 is notched, and the notch is indicated by reference numeral 62. When the seat plate 6 is moved forward and the guide claw 60 is positioned at the notch 62, the seat 2 can be moved up and down to be attached to and detached from the intermediate member 8. On the other hand, it is not preferable that the seat 2 can be easily removed in a normal use state. Therefore, the forward position of the seat 2 in a normal use state is regulated by, for example, the lever device 16 shown in FIG. 2, but the description thereof is omitted because it is not directly related to the present invention.

(5). Others The present invention can be embodied in various ways other than the above embodiment. For example , the locking member does not necessarily have a crank shape, and can be formed in an L shape, for example. That is, it is also possible to fix the skin material 39 to the standing portion 53a of the fitting portion as a shape of only the fitting portion 53 in which the substrate 51 is removed from the locking tool 41 of the embodiment. Moreover, the latching tool does not necessarily need to be plate-shaped, and can be manufactured with a wire, for example.

The above embodiment is applied to the seat, the present invention is, against the back and elbow, can be applied, such as the headrest. Even when applied to these, it is preferable that a combination of clips bayonet. Further, the present chair may include those sofa etc. Various.
