Furniture leg devices

Abstract

This invention provides a structure for a single-legged table that allows for the easy attachment of additional functional components that can enhance the product's value. [Solution] The table has a tabletop 1 and a leg device 2. The leg device 2 has a lower support cylinder 4 fixed to a grounding body 3, an upper support cylinder 5 to which the tabletop 1 is fixed, and an intermediate member 6 connecting the two. The intermediate member 6 has an exposed flange portion 6c, and can support a shelf board 15 or cover 14 directly with the flange portion 6c or via an intermediate support member 13. A split unit 7 that acts as a weight can be used to obtain the necessary stability while making the grounding body 3 as small in diameter as possible, but since the split unit 7 is covered by the cover 14, there is no problem of deterioration in aesthetics. A table with a clean appearance and excellent functionality can be realized.

Description

Technical Field

[0001] The present invention relates to a leg device that constitutes furniture such as a table, and more particularly to a leg device that can support a tabletop independently even when used alone.

Background Art

[0002] For example, regarding a table having a circular or square tabletop, there is a single-leg type (one-leg type) in which a support column (leg column) is erected from the central portion of a grounding body that is stably placed on the floor, and the central portion of the tabletop is fixed to the upper end of the support column (for example, Patent Documents 1 and 2).

[0003] Although tables often have a four-leg type, when adopting the one-leg type as in Patent Documents 1 and 2, most of the legs are hidden under the tabletop, resulting in a neater appearance. Also, when a person uses the table in combination with a chair, the legs do not obstruct the person, so the person can use the table from any direction, which has the advantage of good usability. In particular, when the grounding body is formed in a circular shape as in Patent Document 1, it is possible to prevent the user's toes from getting caught on the grounding body, so it can be said that the appearance and usability are particularly good.

[0004] In Patent Documents 1 and 2, a single cylindrical body is used as the support column. However, in Patent Document 3, regarding a table that uses a tire wheel as the grounding body, the support column is a composite type consisting of a lower support column fixed to the grounding body and an upper support column fixed to the tabletop. An inwardly tapered portion (joint portion) is fixed inside the upper support column, and the tapered portion is inserted inside the lower support column to connect the upper and lower support columns.

Patent Document 3

[0006] Now, for example, in the case of a table, there is a need to place an additional functional component, such as a shelf, in the space below the tabletop, either as an optional item or as standard equipment. In this case, it is reasonable to attach the additional functional component using support columns.

[0007] However, in cases where the leg support is made of only a single pipe, as in Patent Documents 1 and 2, brackets are welded to the outer surface of the support, and additional functional components such as shelves are attached to these brackets. However, welding the brackets is time-consuming, and there are problems with flexibility because the additional functional components cannot be removed when they are no longer needed.

[0008] In Patent Document 3, the entire slender portion provided on the upper support is hidden inside the lower support, and the lower end surface of the upper support and the upper end surface of the lower support are in contact. As a result, the support is essentially the same as being made of a single pipe. Therefore, if an additional functional member is to be attached, a bracket must be welded to the upper or lower support, resulting in the same problem as in Patent Documents 1 and 2.

[0009] The present invention was made against this backdrop, and aims to improve the commercial value of furniture such as tables by providing a leg device that incorporates a useful additional function. [Means for solving the problem]

[0010] The present invention relates to a leg device for furniture that is placed on the floor surface and can support tabletops on its own, and claim 1, which forms a broader concept, It comprises a ground support body for standing on the floor, a lower support cylinder erected upward from the center of the ground support body, an upper support cylinder to which the top plates are fixed at the upper end, and an intermediate member connected to both the lower and upper support cylinders. The aforementioned intermediate member has an exposed portion that is visible from the outside." This is the structure.

[0011] Here, tabletops are primarily horizontal tabletops that allow people to perform various tasks, and function as furniture. In addition to tabletops, this category also includes monitors, whiteboards, projector holders, pin-up boards, and information plates. Therefore, furniture includes tables, electronic display devices, whiteboard devices, projector stands, bulletin board devices, and information board devices.

[0012] The present invention can be developed in various ways under claim 1. For example, in claim 2, "The intermediate member has a lower fitting portion that fits inside the lower support cylinder, an upper fitting portion that fits inside the upper support cylinder, and a flange portion that is integrally connected to the lower fitting portion and the upper fitting portion and is located between the upper support cylinder and the lower support cylinder." This is the structure.

[0013] In the present invention, the lower support cylinder and the upper support cylinder may have the same outer and inner diameters, or they may have different outer or inner diameters, for example, by setting the lower support cylinder to have a larger diameter than the upper support cylinder. Even if the inner diameters of the lower and upper support cylinders are different, this can be easily accommodated by making the outer diameters of the lower and upper fitting portions of the intermediate support member different.

[0014] The invention of claim 3 is, in claim 1 or 2, "The top plate is fixed to the upper end of the upper support column via a support plate, and the shelf board is supported by the intermediate member." This is the structure.

[0015] The invention of claim 4 is, in claim 1 or 2, "The upper support cylinder and the intermediate member are fastened together to the lower support cylinder by bolts inserted through them from above, and a nut into which the bolts are screwed is fixed to the upper end of the lower support cylinder." It is configured as follows.

[0016] In this case, it is possible to use a commercially available product as the nut and weld the nut to a bracket plate fixed to the lower support cylinder by welding or the like. It is also possible to fix a nut plate with tapped holes to the lower support cylinder by welding or the like. It is also possible to form a burring portion on the nut plate and tap it.

[0017] The invention of claim 5 is also a development example of claim 1 or 2, "The lower support cylinder is covered with a cover in which an upper plate is integrally provided at the upper end of the cylinder portion, and the upper plate of the cover is supported by the intermediate member." It is configured as follows.

[0018] The invention of claim 6 is a development example of claim 5, "The lower end of the cover covers or abuts against the grounding body, and a weight for stabilizing the grounding body and the lower support cylinder is arranged inside the cover." It is configured as follows.

[0019] The invention of claim 7 is a development example of claim 5, "An intermediate receiving member for supporting the upper plate of the cover is mounted on the upper part of the lower support cylinder in a state of holding the lower support cylinder, and the intermediate receiving member is composed of a plurality of members separated in the circumferential direction." It is configured as follows.

Advantages of the Invention

[0020] In the present invention, since the intermediate member has an exposed portion, it becomes possible to hold various functions in the leg device by using the exposed portion. That is, it becomes possible to support or attach an additional functional member by using the exposed portion, and the commercial value of furniture can be improved.

[0021] Furthermore, since the intermediate member does not need to be welded to the support column, the manufacturing process can be simplified by eliminating the need to weld brackets to the support column, and it is also easy to adapt if the additional functional member becomes unnecessary. In addition, since the support column does not experience thermal distortion due to bracket welding, there is the advantage of improved dimensional accuracy. Moreover, the intermediate member comes in two types: one that is inserted into the upper and lower support column tubes, and another that is fitted into the upper and lower support column tubes from the outside, allowing for selection depending on the application. This is also one of the advantages of the present invention.

[0022] As described in claim 2, forming a flange portion as an exposed part allows for easy support of shelves, covers, and other components with the flange portion. Furthermore, when a shelf or other component is supported by the flange portion, the flange portion is hidden by that component, thus concealing it from view and resulting in a superior aesthetic appearance.

[0023] Furthermore, by changing the outer diameter of the upper and lower fitting portions of the intermediate member, it is easy to accommodate differences in the outer diameter of the upper and lower support cylinders. In this case, setting the lower support cylinder to have a larger diameter than the upper support cylinder, or making the wall thickness of the upper support cylinder thicker than the upper support cylinder while keeping the outer diameter of the upper and lower support cylinders the same, is beneficial as it improves the overall rigidity of the support cylinders.

[0024] Claim 3 is applicable to tables and counters equipped with a top, but since items can be placed on the shelf, users will not have trouble finding a place to put their belongings, making it very convenient.

[0025] In claim 4, the upper support cylinder and the intermediate member are fastened together to the lower support cylinder with a bolt (long bolt), allowing for quick assembly of the leg device. If a support plate for the top plate is placed at the upper end of the lower support cylinder, fastening this support plate together with the leg device further improves the efficiency of assembly. Furthermore, if a cover is provided as in claim 5, fastening the cover together with the leg device further improves the efficiency of leg device assembly. In addition, since the nut is located at the upper end of the lower support cylinder, the bolt does not need to be excessively long, and commercially available bolts can be used, thus reducing costs.

[0026] As described in claim 5, providing a cover gives the product a substantial appearance, thereby improving its value from a design perspective. It also makes it easier to place weights or other components inside the cover. Furthermore, the top surface of the cover can be used as a luggage rack.

[0027] Minimizing the diameter of the contact points of the leg assembly is desirable for achieving a clean appearance and enhancing the product's value. However, reducing the diameter of the contact points reduces the stability of the furniture. In this regard, concealing the contact points with a weighted cover, as in claim 6, allows for minimizing the diameter of the contact points while ensuring high stability without compromising aesthetics.

[0028] When providing a cover, supporting the cover with a split-type intermediate support member as in claim 7 allows the intermediate support member to be added later, making assembly of the leg device easy. Furthermore, since the height position of the intermediate support member can be set arbitrarily, there is the advantage of being able to support the cover (and shelf board) at the optimal height.

[0030] (1) Basic structure of a table Next, embodiments of the present invention will be described based on the drawings. This embodiment is applied to a table. As shown in Figure 1, the table has a tabletop 1 and a leg device 2 that supports it. In Figure 1, (A) to (C) show a type in which a circular tabletop 1 is supported by a single leg device 2, and (D) shows a type in which an oval tabletop 1 is supported by two leg devices 2. The single-leg type shown in (A) to (C) will be described below, but the structure of the leg device 2 is the same as that of type (D).

[0031] As shown in Figures 2 and 3, the leg device 2 comprises a circular, metal grounding body 3, a lower support cylinder 4 erected from the center of the grounding body 3, an upper support cylinder 5 hanging down from the top plate 1, and an intermediate member 6 connecting the upper support cylinder 5 and the lower support cylinder 4. The grounding body 3 and the lower support cylinder 4 are made of metal, and the lower end of the lower support cylinder 4 is welded to the grounding body 3. The lower support cylinder 4 is held in place by two split units 7 that constitute the weight section.

[0032] A disc-shaped metal (steel plate) support plate 8 is positioned at the upper end of the upper support column 5, and is fixed to the underside of the top plate 1 by screws (not shown). The top plate 1 has embedded threaded inserts into which the screws are threaded, and the support plate 8 has numerous screw insertion holes 9 scattered around its circumference.

[0033] For example, as shown in Figures 1(B) and 1(C), a downward-facing bulge 8a is formed in the center of the support plate 8, and a circular reinforcing plate 10 is fitted onto the bulge 8a from above. The reinforcing plate 10 is welded to the bulge 8a. Furthermore, as shown in Figure 2(C), for example, a notch 11 is formed at the upper end of the upper support cylinder 5, while a group of engagement holes 12 that fit the bulge 11 are formed in the circumferential direction on the reinforcing plate 10. By fitting the bulge 11 and the engagement holes 12 together, the reinforcing plate 10 and the support plate 8 are held in a position where they cannot rotate horizontally relative to the upper support cylinder 5.

[0034] As can be seen from Figure 2(B), the intermediate member 6 has a lower fitting portion 6a that fits inside the lower support cylinder 4, an upper fitting portion 6b that fits inside the upper support cylinder 5, and a flange portion 6c that is integrally connected to the lower fitting portion 6a and the upper fitting portion 6b and exposed to the outside, and the flange portion 6c of the intermediate member 6 is held by the two-part intermediate receiving member 13.

[0035] The cover 14 and the shelf board 15 are supported by the intermediate support member 13. In this embodiment, the lower support cylinder 4 is slightly larger in diameter than the upper support cylinder 5. Therefore, the lower fitting portion 6a of the intermediate member 6 is larger in diameter than the upper fitting portion 6b.

[0036] The cover 14 is made of metal or resin and has a truncated cone shape with a tapered cylindrical portion (skirt portion) 14a that widens at the bottom and a donut-shaped upper plate 14b integrally connected to its upper end, with the upper plate 14b supported by an intermediate support member 13. The shelf board 15 is made of metal (steel plate) (it may also be made of resin) and is formed in a donut shape with a larger diameter than the upper plate 14b of the cover 14, and a rectangular bracket 16 is welded to its lower surface in plan view. The outer diameter of the upper plate 14b is set to be approximately 3 to 6 times the outer diameter of the lower support cylinder 4.

[0037] Then, a disc 17, as shown in Figures 2(B) and 4(B), is welded to the interior of the intermediate support member 13 near the lower end of the lower fitting portion 6a of the intermediate member 6, and a nut 18 is welded to its lower surface (or upper surface). A bolt 19, which is inserted from above through the reinforcing plate 10 welded to the support plate 8, is screwed into the nut 18.

[0038] Therefore, the support plate 8, shelf plate 15, cover 14, and upper support cylinder 5 are fastened together to the lower support cylinder 4 by bolts 19. Note that in Figure 2(B), the disc 17 and nut 18 are shown at a larger scale than other parts to improve visibility. As can be easily understood from Figure 5(C), the lower support cylinder 4 has multiple (2) window holes 4a spaced apart in the circumferential direction that expose a part of the disc 17, and the disc 17 is welded to the upper support cylinder 5 at the location of these window holes 4a. Therefore, welding work can be easily performed.

[0039] As can be seen from Figure 2(B), the protruding portion 11 of the upper support cylinder 5 extends above the reinforcing plate 10, and the head of the bolt 19 is positioned in the space enclosed by the protruding portion 11. Because the protruding portion 11 extends above the support plate 8, a relief recess 20 is formed on the underside of the top plate 1 into which the protruding portion 11 fits.

[0040] (2) Details of each part As shown in Figure 3, the two intermediate receiving members 13 are each semicircular in shape, and when the two are brought into contact, they form a ring. A groove 22 is formed on the inner circumference to fit into the flange portion 6c of the intermediate member 6, and positioning protrusions 23 and positioning holes 24 are formed on the end faces to fit together when they are brought into contact. A lower flange 25, an end rib 26, and numerous intermediate ribs 27 are formed on the outer circumference, and an engaging claw 28 is provided at one of the two ends that are separated in the circumferential direction, which engages elastically against the end rib 26 of the mating member.

[0041] Therefore, the pair of intermediate support members 13 are held in a way that prevents them from falling, by embracing the flange portion 6c of the intermediate member 6, the upper end of the lower support cylinder 4, and the lower end of the upper support cylinder 5. The intermediate support members 13 can also be fixed to the flange portion 6c of the intermediate member 6 with screws. The upper parts of the ribs 26 and 27 of the intermediate member 6 are formed as inclined surfaces to guide the fitting of the upper support cylinder 5.

[0042] The pair of split units 7 that make up the weight section have a group of split weight cases 30 that are split in half and open upwards, and a group of lids 31 that cover the top of the weight cases 30. The split unit 7 is formed by four groups of weight cases 30 and lids 31, and the lower support cylinder 4 is held by two split units 7. The upper end of the split unit 7 is held in an upwardly immovable position by a resin weight retainer 32 attached to the lower support cylinder 4.

[0043] As shown in Figure 3(E), the weight retainer 32 is an arc shape that overlaps a part of the lower support cylinder 4 from the outside, and a boss portion 32a is formed on its inner circumference which fits into a mounting hole 33 formed in the lower support cylinder 4, and an upward-facing engaging claw 34 is provided on the boss portion 32a. The engaging claw 34 is formed as a tongue-shaped body 35 whose base end is on the tip side of the boss portion 32a and which is able to rotate up and down against elasticity, and an upward-facing tab 36 is provided at the rear end (free end) of the tongue-shaped body 35. When the tab 36 is pushed downward, the tongue-shaped body 35 rotates downward, and the engaging claw 34 can be removed from the upper support cylinder 5.

[0044] Each weight case 30 can store weights such as scrap metal. Because weight cases 30 are used, waste materials can be used as weights, which is one of the advantages of this embodiment. As shown in Figure 5, the lid 31 is fixed by a plurality of screws 38, and the weight cases 30 and lid 31, which are stacked on top of each other, are held in place so as not to shift laterally by the engagement of a plurality of engaging protrusions 39 and engaging recesses 40. The weight case 30 is a molded product of synthetic resin, and ribs 41 for screwing in the screws 38 are formed on the inner surface.

[0045] The engaging projection 39 and engaging recess 40 are examples of positioning means, but it is also possible to form the engaging recess 40 on the lower surface of the weight case 30 and the engaging projection 39 on the lid 31, or to form both the engaging projection 39 and the engaging recess 40. Furthermore, it is also possible to form a stepped portion on the lower surface of the lid 31 and the opening of the weight case 30 so that they fit together, or to fix the bottom plate of the weight case 30 to the lid 31 which is overlapping its lower surface with screws.

[0046] For example, as shown in Figure 5, the outer diameter of the grounding body 3 is set to be larger than the outer diameter of the split unit 7, and the pair of split units 7 are held in a manner that prevents lateral displacement by a group of upward-facing engaging claws 42 and upward-facing positioning projections 43 that protrude upward from the grounding body 3.

[0047] There are four pairs of upward-facing engaging claws 42 and upward-facing positioning projections 43, which are arranged alternately in the circumferential direction. Pairs of circumferentially adjacent upward-facing engaging claws 42 and upward-facing positioning projections 43 are formed on a four-part arc-shaped spacer plate 44 located on the lower surface of the grounding body 3. The grounding body 3 has relief holes 45 into which the upward-facing engaging claws 42 and upward-facing positioning projections 43 are fitted from below. The spacer plate 44 is fixed to the grounding body 3 with upward-facing screws (not shown). For this purpose, countersunk holes 46 are formed in the spacer plate 44 into which the screw heads fit, and tapped holes 47 are drilled in the grounding body 3.

[0048] The upward-facing engaging claws 42 of the spacer plate 44 are arranged at 90° intervals in the circumferential direction and are formed in an outward-facing hook shape. On the other hand, as shown in Figure 6(B), an inward-facing flange 48 is provided at the lower end of the cover 14, and four notches 49 are formed in the inward-facing flange 48 to prevent interference with the upward-facing engaging claws 42. The spacer plate 44 is a molded resin product, but sheet metal products and die-cast products can also be used.

[0049] When the cover 14 is dropped in with the notch 49 positioned at the location of the upward engaging claw 42 of the spacer plate 44, its lower end is supported by the outer edge of the grounding body 3 and is held in place by the upward positioning projection 43 to prevent lateral movement. When the cover 14 is rotated horizontally by an appropriate angle, the cover 14 is held in place by the upward engaging claw 42 to prevent it from coming off. In this state, the cover 14 is pressed and fixed to the upper support cylinder 5 by bolts 19.

[0050] (3) Summary In the above configuration, the table is assembled in the following procedure. First, weights such as scrap metal are placed in the group of weight cases 30 and sealed with the lid 31. The group of weight cases 30 is then stacked on the ground base 3 to assemble a pair of split units 7 that hold the lower support cylinder 4. Next, the split units 7 are fitted into the upper support cylinder 5 to hold the pair of split units 7 so that they cannot move upward.

[0051] In this state, the lower weight case 30 is held in place by the upward positioning projection 43 so as not to shift laterally, and the vertically adjacent weight cases 30 are held in place by the engagement of the engaging projection 39 and the engaging recess 40 so as not to shift laterally. Therefore, when the weight retainer 32 is attached to the lower support cylinder 4, the group of split units 7 is held in a state of embracing the lower support cylinder 4. Thus, the split units 7 can be accurately positioned without using screws. Even if the lower support cylinder 4 and the axis of the lower support cylinder 4 are tilted when the table is moved, the ground contact body 3 will not fall off.

[0052] After (or before) positioning the split unit 7, insert the lower fitting portion 6a of the intermediate member 6 into the upper end of the lower support cylinder 4, attach the intermediate receiving member 13 to the intermediate member 6, then place the cover 14 over the split unit 7, fit the upper plate 14b of the cover 14 into the upper fitting portion 6b of the intermediate member 6, then fit the upper support cylinder 5 into the upper fitting portion 6b of the intermediate member 6, and then fit the lower end of the upper support cylinder 5 into the upper fitting portion 6b of the intermediate receiving member 13 while inserting it into the upper plate 14b of the cover 14.

[0053] The bracket 16 to which the shelf board 15 is fixed may be permanently fixed to the upper support cylinder 5, or it may be removable from the upper support cylinder 5. If the shelf board 15 is an optional item, it is preferable to make the bracket 16 detachable. In this case, the upper support cylinder 5 is attached to the intermediate support member 13, and then the shelf board 15 is fitted and installed into the upper support cylinder 5.

[0054] Then, the upper support cylinder 5 is set into the intermediate support member 13, the support plate 8 is fitted onto the upper end of the intermediate support member 13, and then the bolts 19 are screwed into the nuts 18 to press and fix the support plate 8, the intermediate support member 13, the shelf board 15, and the intermediate member 6 to the intermediate support member 13, and then the top plate 1 is placed on top of the support plate 8 and fixed with a group of screws.

[0055] Furthermore, in this embodiment, the flange portion 6c of the intermediate member 6 can be used to support the shelf board 15 and the cover 14, thus providing a table with excellent functionality and aesthetics. Since the flange portion 6c of the intermediate member 6 is hidden by the cover 14 and not visible, the aesthetics are not negatively affected by the presence of the intermediate member 6. The support plate 8 and the upper support column 5 are firmly fixed by a single bolt 19, so assembly can be carried out quickly.

[0056] As in the embodiment, by arranging upward positioning protrusions 43 on the grounding body 3 and holding the vertically adjacent weight cases 30 and lids 31 in a way that prevents lateral movement, there is an advantage in that the multi-stage adjacent split units 7 can be stably held without using screws for fixing. In addition, there are four pairs of upward engaging claws 42 and upward positioning protrusions 43, which are arranged alternately in the circumferential direction. If the circumferentially adjacent upward engaging claws 42 are formed on the spacer plate 44, the grounding body 3 can be made robust with a metal plate (steel plate) or the like while softening the contact with the floor.

[0057] In this embodiment, since the spacer plate 44 is divided equally in the circumferential direction, only one type of spacer plate 44 is needed. Therefore, only one type of mold is required, which helps to reduce costs.

[0058] The embodiments of the present invention have been described above, but the present invention can be implemented in various other ways. For example, when applied to a table, the base, tabletop, shelf, and cover can be rectangular or otherwise. It can also be applied to a table with a clover-shaped tabletop. The cover may be straight or tapered, and it is also possible to place a shelf on the top surface of the cover (supporting the shelf with the cover). It is also possible to form the top plate of the cover so that it protrudes radially from the upper end of the cylindrical part, and the top plate functions as a shelf.

[0059] In this embodiment, the weight is housed in a weight case, but it is also possible to fit a donut-shaped weight into the lower support cylinder without using a weight case. For the intermediate members, it is possible to prepare several types with different flange portion thicknesses (vertical widths) and use a common lower support cylinder and upper support cylinder to construct tables with different tabletop heights. For the ground contact body, cross-shaped or rectangular plate shapes such as those shown in Patent Document 2 can also be adopted.

[0060] The intermediate member can also be H-shaped in cross-section, with a lower support cylinder and an upper support cylinder inserted inside (in this case, the entire intermediate member will be exposed). It is also possible to attach a basket for storing luggage as an optional accessory using the intermediate member. Shelves can also be constructed from wire mesh. [Industrial applicability]

[0061] The present invention can be implemented in leg devices for furniture such as tables. Therefore, it can be used industrially. [Explanation of symbols]
