Description

[Technical field]

[0001] The present invention relates to a chair. [Background technology]

[0002] There is known a chair configuration provided with a luggage carrier on which a person can place a bag or other carry-on items when sitting down. One example of such a chair is disclosed in Patent Document 1 (JP 2009-183532 A). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2009-183532 A (paragraphs 0021-0025, figures 1-4, etc.) Summary of the Invention [Problem to be solved by the invention]

[0004] The luggage carrying section (luggage carrying shelf) of the chair disclosed in Patent Document 1 is configured by attaching a cross bar arranged in the front-to-rear direction to each of the left and right legs, with the luggage carrying section spanning the middle parts of the cross bars. This means that the insertion part of the cross bar into the leg can easily come loose, causing the luggage carrying section to fall onto the installation surface. [Means for solving the problem]

[0005] The present invention is intended to solve the above problems, and has the following objectives: That is, the present invention aims to provide a chair that can prevent baggage, such as carry-on items, from falling onto the installation surface of a baggage placement section on which the baggage is placed.

[0006] As a result of intensive research by the inventors to solve the above problems, the inventors came up with the following configuration: That is, the present invention is a chair having a seat attached to the upper part of two legs, each of the legs having a base extending along an installation surface, a grounding part attached to the base, a first standing part and a second standing part standing from both ends of the base, and a connecting part connecting the first standing part and the second standing part, a luggage placement part is disposed between the bases, the luggage placement part has clamping bodies that clamp each of the bases from above and below, and is detachable from each of the bases.

[0007] This allows the luggage carrier to be securely held on the base, which is part of the leg, so that the luggage carrier will not fall onto the installation surface.

[0008] It is also preferable that the luggage placement portion is provided with a positioning member for preventing misalignment of the ground contact portions in the direction in which the ground contact portions are disposed.

[0009] As a result, even if the legs of a seated person come into contact with the luggage placement section, the position of the luggage placement section will not shift, and luggage placed on the luggage placement section can be easily removed when leaving the seat.

[0010] It is also preferable that at least a part of the outer periphery of the luggage placement section is bent upward.

[0011] This makes it possible to prevent luggage from falling off the luggage placement section.

[0012] It is also preferable that the luggage loading section is a lattice body formed from a plurality of wire rods, and the clamping body is formed by bending a portion of both ends of the lattice body on the base side above or below the base.

[0013] This allows the luggage carrying section to be lighter in weight.

[0014] It is also preferable that the legs are arranged in the left-right direction, and the tip of the clamping body is located flush with or on the inside of the grounding part and the outermost surface position of the base. It is also preferable that the legs are arranged in the left-right direction, and the tip of the clamping body and the positioning body is located flush with or on the inside of the grounding part and the outermost surface position of the base.

[0015] As a result, even chairs equipped with luggage placement sections can be arranged so that the chairs are closely packed together laterally. Effect of the Invention

[0016] According to the configuration of the present invention, the luggage placement portion can be securely held on the base, which is part of the leg, so that the luggage placement portion will not fall off the installation surface. [Brief description of the drawings]

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this specification, "upper", "lower", "front" and "rear", as well as "left" and "right" are defined based on the seated person of the chair 100.

[0019] As shown in Figures 1 to 4, the chair 100 in this embodiment has two legs 10 arranged at a required distance in the left-right direction, a seating section 20 and a back section 30 attached to the legs 10, and a luggage placement section 40 arranged below the seating section 20 and between the two legs 10.

[0020] The leg 10 has a base 11 extending along the installation surface, a first standing portion 12 and a second standing portion 13 standing upward from both ends of the base 11, and a connecting portion 14 connecting the first standing portion 12 and the second standing portion 13. In the leg 10 in this embodiment, the base 11, the first standing portion 12, the second standing portion 13, and the connecting portion 14 are integrally formed by bending a tube body. A resin cap 15 is detachably attached to the lower surface of the base 11 as a grounding portion. As shown in FIG. 3, in both the left and right legs 10, the standing base portion 12A of the first standing portion 12 from the base 11 is bent inward and then raised upward, so that the first standing portion 12 is raised at a position inside the second standing portion 13. As a result, in the chairs 100 with the luggage placement section 40 removed, stacking of the chairs 100 can be easily achieved by inserting the rear part of the underside (the underside part on the back 30 side) of the seating section 20 of the upper chair 100 from the front side of the upper surface of the seating section 20 of the lower chair 100. The distance between the left and right legs 10 gradually narrows as one moves from the base 11 side (lower side) to the connecting section 14 side (upper side).

[0021] As shown in FIG. 4, the first standing portion 12 and the second standing portion 13 are gradually spaced from each other from the side of the base 11 (lower side) to the side of the connecting portion 14 (upper side). One of the first standing portion 12 or the second standing portion 13 (here, the second standing portion 13) protrudes upward from the horizontal portion of the connecting portion 14. The protruding portion 16 is formed by the protruding portion of the second standing portion 13 that is bent so as to stand up along the protruding portion of the second standing portion 13 and the bent portion of the tip of the connecting portion 14 in the required length range. The two pipes in the protruding portion 16 can be integrated by welding or the like. As shown in FIG. 5, the leg 10 in this embodiment is D-shaped in side view.

[0022] As shown in FIG. 6, the resin cap 15 in this embodiment has a support portion 15A formed with a width dimension approximately equal to the outer diameter dimension of the pipe of the base 11, and a locking portion 15B protruding outward from the support portion 15A on the left and right side surfaces of the chair 100. The locking portion 15B is formed in a J-shape in a plan view. The resin cap 15 thus formed is attached to the base 11 from the bottom surface of the resin cap 15 by a screw (not shown). A form in which a non-slip sheet is attached to the bottom surface of the resin cap 15 can also be adopted. By adopting the resin cap 15 having the locking portion 15B in this way, it is possible to prevent the leg 10 from spreading outward to the left and right when used alone, and to connect multiple chairs 100 in a state of almost close contact in the left and right direction as shown in FIG. 7 and FIG. 8.

[0023] A luggage placement section 40 is disposed between the bases 11 of the left and right legs 10 in a spanning state. The luggage placement section 40 in this embodiment has a luggage placement body 41 on which luggage is placed and a clamping body 42 that clamps the base 11 from above and below at both ends of the luggage placement body 41 on the base 11 side. The luggage placement body 41 in this embodiment is formed of a plurality of metal wire rods 43 and a frame body 44. The frame body 44 here is formed by forming the wire rods 43 into a frame shape. The luggage placement body 41 in this embodiment is formed into a lattice body by a plurality of frame bodies 44 arranged so that the longitudinal direction is the front-rear direction, and a plurality of frame bodies 44 and wire rods 43 arranged so that the longitudinal direction is the left-right direction. In addition, both longitudinal ends 45 of a frame body 44 arranged in the front-to-rear direction and constituting part of the outer peripheral edge of the luggage carrying body 41 are bent diagonally upward within a required length range, thereby preventing luggage from falling off the luggage carrying body 41.

[0024] The clamping body 42 in this embodiment has a lower clamping body 43A in which both ends (both ends on the base 11 side) of the wire 43 arranged at the front and rear positions are bent toward the lower side of the base 11, and an upper clamping body 44A in which both left and right ends of the frame body 44 are placed on the upper side of the base 11. The tip of the lower clamping body 43A is accommodated within the range of the planar position of the base 11, and the tip of the upper clamping body 44A is accommodated in a position outside the planar position of the base 11 and inside the outer position of the resin cap 15 (see Figs. 1, 3, and 10). The load placement section 40 thus formed is attached to the chair 100 by clamping the base 11 of one leg 10 with the right or left clamping body 42, and then clamping the base 11 of the other leg 10 with the left or right clamping body 42. In this embodiment, the left and right legs 10 are not positioned in the left-right direction, so that the left and right legs 10 can be moved, and the luggage placement portion 40 can be easily attached.

[0025] According to the configuration of the baggage placement unit 40 in this embodiment, when the baggage placement body 41 is bent downward by placing the baggage on it, the clamping body 42 rotates downward (in the direction of the arrow A in FIG. 10) along the outer circumferential surface of the base 11. As a result, the tip of the lower clamping body 43A moves to a position outside the base 11 from its planar position before the baggage is placed. On the other hand, the tip of the upper clamping body 44A moves inside the base 11 from its planar position before the baggage is placed (in the opposite direction to the direction of the arrow A in FIG. 10), but the tip of the upper clamping body 44A before the baggage is placed is located sufficiently outside the base 11. Therefore, even when the baggage is placed, the tip of the upper clamping body 44A is still located outside the base 11 from the contact portion with the base 11. For the above reasons, it is advantageous in that the clamping state of the clamping portion 42 relative to the base 11 can be made stronger when luggage is placed on the luggage carrying body 41 than the clamping state of the clamping portion 42 relative to the base 11 before luggage is placed on the luggage carrying body 41.

[0026] In addition, since the wire 43 in the foremost position is disposed immediately behind the front plastic cap 15, and the wire 43 in the rearmost position is disposed immediately before the rear plastic cap 15, even if the luggage placement section 40 moves only slightly in the front-rear direction, the lower clamping body 43A of the wire 43 in the foremost position or the wire 43 in the rearmost position will abut against the plastic cap 15. The lower clamping body 43A abuts against the front or rear surface of the plastic cap 15, thereby restricting the movement of the luggage placement section 40 in the front-rear direction. In this manner, the lower clamping body 43A in this embodiment also functions as a positioning body that prevents the luggage placement section 40 from being displaced in the front-rear direction (the direction in which the plastic cap 15 is disposed).

[0027] The seating portion 20 in this embodiment is formed of a perforated plate made of synthetic resin with a plurality of seat through-holes 22 that penetrate in the vertical direction. As shown in Fig. 9, an inverted U-shaped fitting portion 24 that opens downward is formed along both left and right edge portions on the bottom surface of the seating portion 20. The seating portion 20 is detachably attached to the legs 10 (connecting portions 14) by fitting the fitting portions 24 into the connecting portions 14 of the left and right legs 10, respectively.

[0028] The back 30 in this embodiment is made of the same material as the seat 20, and is formed independently of the seat 20. The back 30 is formed as a perforated plate with a plurality of back through holes 32 that penetrate in the front-rear direction. As shown in FIG. 11, the back 30 has insertion parts 36 with recessed holes 34 that open downward at both ends of the bottom surface, and the back 30 is detachably attached to the legs 10 (protruding parts 16) by inserting the protruding parts 16 of the left and right legs 10 into the recessed holes 34 of the insertion parts 36. In addition, the insertion parts 36 have step parts 38 formed at the parts where the planar position overlaps with the seat 20, and by attaching the back 30 to the protruding parts 16, the step parts 38 press a part of the seat 20 from the top to the bottom, preventing the seat 20 from escaping from the connecting parts 14.

[0029] The chairs 100 in this embodiment can be connected in the left-right direction with the luggage placement sections 40 attached, as shown in Figures 7 and 8. Furthermore, when the chairs 100 are not in use, if the luggage placement sections 40 are removed from the legs 10, the chairs 100 can be stored in a vertically stacked state.

[0030] Although the chair 100 according to the present invention has been described in detail based on the embodiment, the present invention is not limited to the above embodiment. For example, in the above embodiment, the seating portion 20 and the back portion 30 are independent of each other, but the back portion 30 may be formed integrally with the seating portion 20. Also, the back portion 30 may be omitted.

[0031] In the above embodiment, the base 11, the first standing portion 12, the second standing portion 13, and the connecting portion 14 of the leg 10 are integrally formed by the tube body, but the present invention is not limited to this form. The leg 10 may be formed by assembling the base 11, the first standing portion 12, the second standing portion 13, and the connecting portion 14, which are individually prepared, by welding or the like. The leg 10 may be formed of a material other than the tube body. In the above embodiment, the connecting portion 14 connects the upper ends of the first standing portion 12 and the second standing portion 13 to each other, but the present invention is not limited to this form, and the connecting portion 14 may be formed by connecting the middle portions of the first standing portion 12 and the second standing portion 13 to each other.

[0032] In the above embodiment, the clamping body 42 of the load placement section 40 has a lower clamping body 43A in which both ends of the wire 43 on the base 11 side are bent toward the lower side of the base 11, and an upper clamping body 44A in which both ends of the frame body 44 on the base 11 side are placed on the upper side of the base 11, but is not limited to this form. The clamping body 42 may have an upper clamping body (not shown) in which both ends of the wire 43 on the base 11 side are bent toward the upper side of the base 11, and a lower clamping body (not shown) in which both ends of the frame body 44 on the base 11 side are placed on the lower side of the base 11, and the load placement section 40 may be suspended by the upper clamping body. In this case, both ends of the frame body 44 on the base 11 side at the position close to the resin cap 15 function as positioning bodies.

[0033] Furthermore, although the luggage carrying body 41 of the luggage carrying section 40 in the above embodiment is exemplified as being formed by the wire material 43 and the frame body 44, the luggage carrying body 41 may be formed by only the wire material 43 or only the frame body 44. Furthermore, it is also possible to adopt a form in which a plate body is processed into sheet metal, or a form in which a plate-like luggage carrying body 41 is formed by assembling a plurality of plate bodies by welding. When the luggage carrying body 41 is formed by using a plate body, the clamping body 42 can be formed by attaching the plate material or the wire material 43 to the luggage carrying body 41.

[0034] In the above embodiment, the lower clamping body 43A is used as the positioning body, but the present invention is not limited to this. Although not shown, a separately formed positioning body may be disposed on the load carrying body 41. When a separate (independent) positioning body is disposed in this manner, the position of the tip of the positioning body is preferably flush with or inside the outermost surface positions of the resin cap 15 and the base 11.

[0035] In the above embodiment, the chair 100 is exemplified in which the legs 10 are arranged at a required interval in the left-right direction, but the legs 10 may be arranged at a required interval in the front-rear direction. In this case, in order to attach the back 30, the first and second standing parts 12 and 13 of the legs 10 arranged on the rear side are each made to protrude upward beyond the connecting part 14, thereby forming the protruding standing part 16 for attaching the back 30.

[0036] In addition to the modified examples described above, it is also possible to adopt a form in which the modified examples described in the embodiment are appropriately combined. [Explanation of symbols]
