Description

  The present invention relates to a chair having an improved attachment portion for a tension member of a load support such as a seat and a backrest.

A chair seat used for office work or the like is usually provided with a cushion material such as urethane on the upper part of the substrate constituting the skeleton part, and a sheet-like tension material extending from the outer surface of the cushion material to the outer edge of the substrate. Covered.
When attaching this type of chair upholstery material, it is easy to replace the upholstery material at the time of fouling, etc., and it is easy to give stable tension to the entire area of the upholstery material. A technique is often used in which the peripheral edge of the substrate is narrowed on the lower surface side of the substrate, thereby fixing the tension member to the cushion material and the substrate (see, for example, Patent Documents 1 and 2).

In the chairs described in Patent Documents 1 and 2, a bag-like insertion hole is provided in the peripheral portion of the tension member that wraps the outer side surface of the cushion material and the outer peripheral portion of the substrate, and a tightening string is inserted into the insertion hole. Thus, the ends of the fastening string are bound together on the lower surface side of the substrate. On the lower surface side of the chair, a locking projection for restricting the displacement of the fastening string toward the center of the substrate is provided, thereby preventing the displacement of the tension material.
In this chair, the fastening cord can be easily attached to the cushion material and the substrate by fastening the fastening cords in a loop shape on the lower surface side of the substrate and binding the ends together, and the fastening cord. By managing the length of the bundling portion of the strip, there is an advantage that variation in tension acting on the tension material can be reduced.

Japanese Patent No. 3728576 Japanese Patent No. 4255670

In the chairs described in Patent Documents 1 and 2, the locking protrusions are formed only in the direction of receiving the tightening string that is to be narrowed inward. However, when the tension material is actually stretched between the cushioning material and the substrate, not only the direction in which the peripheral edge of the tension material tightened by the tightening string tends to squeeze inward, but also spread outward. It has been found that the direction is also displaced.
As a cause of this, for example, when the substrate or cushion material is substantially rectangular in plan view, if the peripheral portion of the tension member is tightened by the fastening string, the substrate or cushion material on the peripheral portion of the tension member is The part corresponding to the vicinity of the corner is most strongly pulled by the fastening string, but the tensile force is relatively weak in the part corresponding to the vicinity of the straight part between the adjacent corners on the peripheral edge of the tension member. The part is expected to be displaced so as to partially spread outward due to the tension of the tension member.

  Therefore, the present invention is intended to provide a chair that can appropriately regulate the displacement of the fastening string and the peripheral edge portion of the upholstery material and suppress the displacement of the upholstery material.

The chair according to claim 1 employs the following configuration in order to solve the above problems.
A substrate forming a skeleton, a cushion material disposed on the surface side of the substrate, a tension material covering at least the outer surface of the cushion material and the outer peripheral edge of the substrate, and a peripheral edge of the tension material. The tension support is provided with a tightening string that is tightened on the back surface side of the substrate to bind the end portions together in a state where the tension material covers the outer side surface of the cushion material and the outer peripheral edge of the substrate. In the chair provided with a body, the board includes a first locking means for restricting displacement of the tightened string in the direction of the center of the board, and the tightened string in the direction toward the outside of the board. and second locking means for regulating the displacement is provided, et al is, the first locking means includes a first side wall projecting backstage from the back surface of the substrate, from the vicinity of the projecting end of the first side wall A first projecting wall projecting outward of the substrate, and the second engagement The means includes a second side wall projecting backward from the back surface of the substrate, and a second projecting wall projecting inward of the substrate from the vicinity of the projecting end of the second side wall. A concave groove continuous in the circumferential direction of the substrate is formed, the first side wall is constituted by an inner wall of the concave groove, and the second side wall is constituted by an outer wall of the concave groove. It is a feature.
As a result, when the fastening string inserted through the peripheral edge of the tension member is tightened on the back side of the substrate with the tension material covering the outer side surface of the cushion material and the outer peripheral edge of the substrate, the tightening string The displacement in the substrate center direction is regulated by the first locking means, and the displacement of the fastening string in the substrate outer direction is regulated by the second locking means. Therefore, not only the displacement that tends to squeeze inside the peripheral edge of the tension member, but also the displacement that tries to spread outward is regulated.
In this case, the peripheral portions of the tightening string and the tension member are reliably regulated by the first projecting wall and the second projecting wall. In addition, even when the peripheral portion of the tightening cord or the tension member is not in direct contact with the first projecting wall or the second projecting wall, the displacement of the tightening cord or the tension material is the first side wall or the second side wall. Regulated by.
In this case, when the tension member is attached, the peripheral portion of the tightening string or the tension member is pushed into the concave groove continuous in the circumferential direction of the substrate while the peripheral portion of the tightening string or the tension member is first projected. It can arrange | position inside a wall or a 2nd protrusion wall. Therefore, the tension member can be easily attached.

A bag-shaped insertion hole 17 is provided along the circumferential direction in the peripheral portion 15 a of the upholstery material 15 that is arranged around the lower surface side of the peripheral portion of the substrate 13. The insertion hole portion 17 is broken at a part in the circumferential direction of the peripheral edge portion 15a of the tension member 15, and the tightening string 18 is inserted from the broken portion. In the state where the tension material 15 wraps the tension material 15 from the outer side surface of the cushion material 14 to the outer peripheral edge portion of the substrate 13, the fastening string 18 is tightened on the lower surface side of the substrate 13. In this state, both end portions 18a and 18a are bound with a predetermined tension.

  Here, a concave groove 19 extending in the circumferential direction is formed on the lower surface of the outer peripheral edge portion of the substrate 13, and the peripheral edge portion 15 a of the tension member 15 is fitted into the concave groove 19 together with the tightening string 18. It has become. The concave groove 19 includes an annular first side wall 24 projecting downward from the lower surface of the substrate 13, and an annular second sidewall 25 projecting downward from the lower surface of the substrate 13 at a position spaced outside the first sidewall 24. , Is formed by. In this embodiment, a part of the first side wall 24 is continuously formed on the root side of the shielding wall 16. In other words, the shielding wall 16 is formed continuously with the protruding end of the first side wall 24.

They are arranged adjacent to each other with a predetermined distance in the outgoing direction. That is, the first protruding wall 26 and the second protruding wall 27 are arranged in a staggered manner with the concave groove 19 interposed therebetween.
Here, the first projecting wall 26 and the second projecting wall 27 provided adjacent to the regions corresponding to the straight portions 13b on the left and right sides and the straight portion 13b on the front side are concave grooves as shown in FIG. Each tip extends to a position that is approximately half the length of the 19 groove width.

  In the chair 1 of this embodiment, when the cushioning material 14 is disposed on the substrate 13 and the tensioning material 15 is attached thereto, first, the tensioning material is applied to the outer side surface of the cushioning material 14 and the outer peripheral edge of the substrate 13. 15, and the peripheral portion 15 a of the tension member 15 is fitted into the concave groove 19 of the substrate 13 together with the fastening string 18 on the lower surface side of the substrate 13. At this time, at each corner portion 13a and the straight portion 13b on the rear side, the fastening string 18 and the peripheral edge portion 15a of the upholstery material 15 are pushed over only the first projecting wall 26 into the concave groove 19, In the straight portion 13b and the straight portion 13b on the front side, the fastening string 18 and the peripheral portion 15a of the tension member 15 are pushed over the first projecting wall 26 and the second projecting wall 27 into the concave groove 19. Put in.

  Next, in this state, both ends of the tightening string 18 drawn out from the insertion hole 17 at the peripheral edge of the tension member 15 are tightened using a special instrument, and in this state, both ends of the tightening string 18 are tightened. Bond together. Note that the tightening of the tightening string 18 can also be performed manually by an operator. Thus, when the both ends of the tightening string 18 are tightened, the tightening string 18 and the peripheral edge 15a of the tension member 15 are the base material in the regions corresponding to the respective corner portions 13a and the rear straight portion 13b of the substrate 13. In the region corresponding to the straight portions 13b on both the left and right sides of the substrate 13 and the straight portion 13b on the front side, the fastening string 18 and the peripheral portion 15a of the tension member 15 are partially formed on the base material. Displacement in the outward direction, and in other parts, it tends to be displaced in the direction of the center of the substrate. At this time, the displacement of the fastening string 18 and the peripheral portion 15a of the tension member 15 in the center direction of the substrate is regulated by the first side wall 24 and the first protruding wall 26, and the peripheral portion of the tightening string 18 and the tension member 15 The displacement of 15 a in the substrate outer direction is regulated by the second side wall 25 and the second protruding wall 27.

  As described above, in the chair 1 according to this embodiment, in addition to the first side wall 24 and the first projecting wall 26 which are the first locking means, the second surface is formed on the lower surface of the substrate 13 of the seat body 4. Since the second side wall 25 and the second projecting wall 27 that are the locking means are provided at appropriate positions, not only the displacement that tends to squeeze inside the peripheral edge portion 15a of the tension member 15 but also the outer side tends to spread outward. Displacement can also be regulated appropriately. For this reason, it is possible to more reliably suppress the stretching of the upholstery material 15 in various directions.

  In particular, in the chair 1 according to this embodiment, the second side wall 25 and the second protrusion are formed on the straight portions 13b on both the left and right sides and the straight portion 13b on the front side of the thick substrate 13 of the cushion material 14 stacked on the upper surface. Since the wall 27 is provided, it is possible to appropriately regulate the displacement that tends to spread to the outside of the peripheral edge portion 15a of the tension member 15 due to the tightening of the tightening string 18.

  In the chair 1 according to this embodiment, the first locking means is constituted by the first side wall 24 and the first protruding wall 26, and the second locking means is the second side wall 25 and the second protruding wall. 27, the detachment of the peripheral edge 15a of the tension member 15 from the concave groove 19 can be reliably regulated by the first projecting wall 26 and the second projecting wall 27, and the tightening cord 18 and the peripheral edge 15 a of the tension member 15 are not directly in contact with the first protrusion wall 26 and the second protrusion wall 27, the displacement of the tightening string 18 and the tension member 15 is caused by the wall of the groove 19. It can be regulated by a certain first side wall 24 and second side wall 25.

Furthermore, in the chair 1 according to this embodiment, the concave groove 19 is provided on the lower surface of the substrate 13 so as to be continuous in the circumferential direction of the substrate 13, and the first side wall 24 is configured by the inner wall of the concave groove 19. In addition, since the second side wall 25 is constituted by the outer wall of the groove 19, when the tension member 15 is attached, the fastening string 18 and the peripheral portion 15 a of the tension member 15 are connected to the groove 19 on the substrate 13. The fastening strip 18 and the peripheral edge 15a of the upholstery material 15 can be easily arranged inside the first projecting wall 26 and the second projecting wall 27 while being continuously pushed into the inside. For this reason, the tension member 15 can be easily attached. Further, since the displacement of the fastening string 18 and the peripheral edge portion 15a of the upholstery material 15 is restricted within the continuous concave groove 19, it is possible to make the upholstery material 15 more difficult to bend.
However, it is not always necessary to form the continuous concave groove 19 on the lower surface of the substrate 13, and the first side wall 124 and the second side wall 125, which are narrow, as in the second embodiment shown in FIG. Are intermittently projected on the lower surface of the substrate 113 along the extending direction of the fastening cord 18, and the first projecting wall 126 and the first projecting wall 126 are disposed in the vicinity of the projecting ends of the first and second sidewalls 124 and 125, respectively. The two protruding walls 127 may be provided continuously.

  Moreover, in the chair 1 which concerns on this embodiment, the 1st protrusion wall 26 and the 2nd protrusion wall 27 which are provided in the linear part 13b are arrange | positioned adjacent to mutually spaced apart in the extension direction of the fastening string 18. Therefore, the extending length of the first protruding wall 26 and the second protruding wall 27 can be sufficiently extended without causing contact between the tips of the first protruding wall 26 and the second protruding wall 27. . For this reason, the first projecting wall 26 and the second projecting wall 27 can be easily bent and deformed when the fastening string 18 and the peripheral portion of the tension member 15 are attached. Therefore, this makes it easy to attach the tension member 15.

  In particular, in the case of this embodiment, the first projecting wall 26 and the second projecting wall 27 that are provided adjacent to the straight line portion have a groove width of the concave groove 19 (a separation width between the first side wall 24 and the second side wall 25. ), Each tip end extends to a position that is approximately half the length, so that the wide range of the concave groove 19 is closed by the first and second protruding walls 26 and 27, and the tension from the concave groove 19 is increased. It is possible to effectively prevent the peripheral edge portion 15a (clamping string 18) of the material 15 from falling off. Further, as in this embodiment, even when the respective leading end portions of the first projecting wall 26 and the second projecting wall 27 are extended to a position that is substantially half the groove width of the recessed groove 19, at a minimum, If the fastening string 18 is set so that it can pass, the operation of inserting the peripheral edge portion 15a of the tension member 15 into the concave groove 19 may be hindered by the first protruding wall 26 and the second protruding wall 27. Absent.

FIG. 9 is a view showing the lower surface of the main part of the substrate 213 according to the third embodiment of the present invention.
In this embodiment, the 1st protrusion wall 226 and the 2nd protrusion wall 227 which are provided in a linear part are arrange | positioned in the position where a front-end | tip part mutually opposes.
In the case of this embodiment, since the front ends of the first protruding wall 226 and the second protruding wall 227 are arranged to face each other, the displacement direction of the tightening string 18 and the peripheral portion 15a of the tension member 15 may change. Even if it exists, displacement of the peripheral part 15a of the fastening cord 18 or the tension | tensile_strength material 15 is reliably controlled by either one of the 1st protrusion wall 226 and the 2nd protrusion wall 227.

FIG. 10 is a view showing the lower surface of the main part of the substrate 313 according to the fourth embodiment of the present invention.
In this embodiment, the first projecting wall 326 and the second projecting wall 327 provided in the straight portion are such that a part of the tip part is opposed to each other and a part of the remaining part is separated in the extending direction of the fastening string 18. Are arranged to be.
In this embodiment, even if the displacement direction of the tightening cord 18 or the peripheral portion 15a of the tension member 15 may change, the tightening cord by either one of the first projecting wall 326 and the second projecting wall 327. 18 and the displacement of the peripheral portion 15a of the upholstery material 15 can be reliably regulated.
In addition, the first projecting wall 326 and the second projecting wall 327 are such that only a part of the tip part is opposed to each other and the remaining part is separated in the extending direction of the tightening string 18, so that the first projecting wall The wall 326 and the second projecting wall 327 extend long along the extending direction of the tightening string 18. For this reason, the first projecting wall 326 and the second projecting wall 327 can be easily bent and deformed when the fastening string 18 and the peripheral portion 15a of the tension member 15 are attached. For this reason, attachment of the upholstery material 15 can be facilitated.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, although the above-described embodiment is an embodiment in which the load support is a seat, a similar structure can be adopted for the backrest body of the backrest.
