Description

  The present invention relates to a bench that is functionally folded while being a sturdy bench on which 3 to 4 people can sit, and that is easy to transport and stack.

  Conventionally, as a chair on which 3 to 4 people can sit down at the same time, there is a bench installed in a park or the like, and it is also used in a venue where a large number of people gather.

  There is also a bench technology that facilitates transportation by folding and does not take up storage space (see, for example, Patent Document 1).

  Further, there is a bench technology that facilitates transportation by folding and does not take up storage space (see, for example, Patent Document 2).

JP 7-246132 A Registered Utility Model No. 30628804

  Conventionally provided benches are seated by 3 to 4 people, so there are few folding types in terms of strength maintenance and cost, and most are fixed types. In addition, the fixed type has inconveniences and disadvantages that it is difficult to move and stack because it does not fold the legs.

  Further, the folding bench disclosed in Japanese Patent Laid-Open No. 7-246132 is designed to be a folding bench that guarantees the strength of a seat that directly takes a large weight and is comfortable to sit on. A folding bench comprising a frame member, an X-shaped leg set attached to both ends of the support frame member so as to be foldable, and a seat for seating on the tubular tube surrounding the two support frame members arranged side by side.

  However, this bench connects a pair of X-shaped leg sets with a long support frame material, and the support frame material constitutes a seat seat stretched in a tubular shape with a seat, so the seating comfort is not particularly bad. However, when 3 to 4 people are seated, the middle of the seat is loosened, and the weight applied to the intersection of the X-shaped leg set becomes very large, so that there is a concern in terms of durability.

  Furthermore, the folding bench disclosed in the registered utility model No. 30628804 is easy to carry and store by folding, but the configuration is that the seating surface is a lattice, and each axis is placed between the lattices. Although each leg rotates and fits in the center, the seating surface is a lattice, so the sitting comfort is extremely poor, and the legs located on the left and right form an unstable shape, so the weight balance depends on the number and position of the person sitting It is a bench with many inconveniences and drawbacks that can cause it to fall over.

  In order to eliminate the inconveniences and disadvantages of the conventional bench as described above, the present invention provides a foldable bench as claimed in claim 1, wherein the seat plate has a width and length on which 3 to 4 people can sit. A rectangular curtain with a predetermined width and length is attached to the part, and the left and right in the longitudinal direction are opposed to the part closer to the center of the predetermined length from the end on the left and right short sides in the longitudinal direction of the curtain. A pair of two bases attached to the base and the two bases facing each other connected by a long reinforcing rod to the base with a hinge and two sets of legs The body is folded back so that it can be folded on the back of the seat, and the holding base provided on the inner side of the leg and the shaft base on the back of the seat are movably connected by a gas spring bar, and along the reinforcing bar The support lock plate is hinged to the provided board and is located outside the leg. By attaching the support rod to the curtain plate corners, with the assembly of the left and right legs is easy, assembled stable leg and fold also constitutes an easy bench.

  According to a second aspect of the present invention, a lock device is provided on the reinforcing rod described above, and an engagement hole of the lock device is provided on the edge of the leg body, thereby providing a bench that can securely lock the folded leg body.

  The bench in the present invention has a flat seat plate so that it can be sat comfortably, and the legs provided on the back of the seat plate are foldable, and the support lock plate and gas spring bar are used together for a very stable configuration. Provide a bench.

  When assembling the leg, if the leg is lifted after releasing the locking device, the leg is automatically raised by the gas pressure of the gas spring rod, and the leg can be assembled quickly and surely by the support lock plate.

  Furthermore, when folding the leg, if the support lock plate is tilted and then folded, the gas spring bar will shrink and fold in conjunction with tilting the leg, and it will be automatically fixed by the lock device. There is no danger of opening the door without lifting it, so a bench that can be carried with confidence is constructed.

  In addition, since it folds flat to the height of the curtain when fully folded, it can be stacked in two or three steps as it is, and it can easily be stored vertically in a narrow space. By doing so, it is possible to provide a functional folding bench that cannot be seen in the past and can be transported many times.

  An embodiment of the folding bench of the present invention will be described with reference to a perspective view shown in FIG. 1, a front view shown in FIG. 2, a front view showing a folded state shown in FIG.

  The material of the bench 1 according to the present invention is made of cedar wood, and a seat plate 2 having a length of about 1,450 mm × 400 mm and a thickness of about 20 mm to 30 mm, assuming that three to four people can sit comfortably. On the back surface of the seat plate 2, there are two on the left and right short sides on the inner side, in which a curtain plate 3 having a width of about 60 mm and a thickness of about 15 mm is attached to the inner side about 10 mm to 20 mm from the periphery. A pair of foldable legs 4 and a gas spring bar 5 are provided.

  Hereinafter, the detailed description of FIGS. 4 to 7 will be given, but the two legs formed on the back surface of the seat plate 2 are exactly the same on the left and right sides, so only one side is shown for some drawings. Will be explained. First, a set of two sheets having a height of 15 mm, a width of 40 mm, and a length of 100 mm is formed in a portion about 70 mm away from the end on the left and right short sides in the inner longitudinal direction of the curtain plate 3 provided on the back surface of the seat plate 2. The bases 6 and 6 are attached in parallel to the adjacent short-side curtain plate 3, and are provided with a width of about 20 × height of 15 mm so as to connect the two bases 6 and 6 facing each other in the longitudinal direction. X Two long reinforcing rods 7 and 7 each having a length of 1150 mm are attached to the back surface of the seat plate 2 with a certain interval.

  Further, on the bases 6 and 6 which are a set of two pieces as described above, a pair of legs 4 and 4 each having a height of 350 mm × a width of 350 mm and a thickness of 40 mm are seated with hinges 8. The plate 2 is foldably connected so that it can be folded back, and a corner member of the curtain plate 3 outside the leg 4 has a height 56 mm × length 30 mm as a supporting member when the leg 4 is raised. A support rod 9 made of square material is attached as shown in FIGS. 6 and 7 to prevent the leg 4 from falling to the curtain 3 side.

  Next, the holding base portion 10 of the gas spring bar 5 is attached to either the left or right side of the lower portion of the inner side surface of the leg 4 described above, and the shaft base portion 11 serving as the opposing member is attached to the back surface of the seat plate 2. After the shaft base 11 is provided in a portion extending a little more in the middle between the reinforcing bars 7 and 7, the base of the gas spring rod 5 is fixed to the shaft base 11 and the distal end side that expands and contracts is described above. The movable base is fixed to the holding base portion 10 of the leg body 4 so that the leg body 4 can be held by expanding and contracting in conjunction with the tilting or raising of the leg body 4. In addition, the position of the holding base 10 attached to the leg 4 described above is shifted from each other so as to intersect with the gas spring bar 5 of the leg 4 on the opposite side, and is attached closer to the reinforcing bars 7 and 7.

  In addition, on the inner side of the leg 4 described above, a substrate 12 is attached along the reinforcing rod 7, and a support lock plate 14 with a finger hanging recess 13 is attached to the substrate 12 by a hinge 8 connection. . Furthermore, a push latch 16 with a release button is attached to the reinforcing bar 7 as a locking device 15 when the leg 4 is tilted, and an engagement hole 17 into which a claw of the push latch 16 fits is provided at the end of the leg 4. A pair of legs 4, 4 that are provided at the edges and are formed by attaching a rubber plate 18 to the contact portion of the support bar 9 at the outer lower part of the leg 4, and the back of the seat 2 The folding bench 1 is configured to be attached to the left and right of the curtain plate 3 in the longitudinal direction.

  Since the bench 1 according to the present invention is configured as described above, when the leg 4 is assembled, the push latch 16 positioned at the edge of the two legs 4 and 4 folded in the curtain 3 is provided. When it is triggered after being released, it is automatically caused by the gas pressure of the gas spring bar 5 attached to and interlocked with the leg 4 to raise the leg 4 vertically. Then, when the finger lock recess 13 of the support lock plate 13 is hooked and raised vertically as shown in FIG. 5, the outer surface of the leg 4 is supported by the support rod 9 positioned at the corner of the curtain plate 3. The inner side surface is held by the two legs 4 and 4 in a state of being reliably stabilized by the support lock plate 13 and the gas spring rod 5 described above. When further folding, after the support lock plate 13 is tilted horizontally, the gas spring bar 5 is contracted and folded in conjunction with the leg 4 being tilted, and the tabs of the push latch 16 are attached to the edges of the leg 4. By fitting in the provided engagement hole 17, the leg 4 is completely locked as shown in FIG. 8, so that the leg 4 does not open even if it is lifted or fallen carelessly, as shown in FIG. A bench 1 that can be folded thinly is constructed.

  Since the gas spring rod 5 in the present invention is longer than the central portion of the seat plate 2, the opposing gas springs 5 are attached so as to be shifted from each other. There is no problem. Furthermore, although the locking device 15 of the leg 4 is attached to the reinforcing bar 7, it may be attached to another part. In addition, the dimensions shown in the figure are basic, but there is no problem even if the size is changed, and none of them is particularly limited.
