No. 588,422 Int. Cl. F16m 11/20 U.S. Cl. 248188.7 33 Claims ABSTRACT OF THE DISCLOSURE An apparatus and method for forming a m'ultileg furniture base wherein the legs are formed of wood and radially extend from a centrally disposed hub member. The hub member is secured thereto by a plurality of pairs of arms; one arm of each pair being adapted to be inserted within a bore formed in the leg, and the other arm of each pair being adapted to lie beneath the leg. The arms are in turn secured together by appropriate means, such as screws, so as to urge them towards each other to grip the leg portion disposed therebetween.

This invention relates to supports, and, more particularly, to supports having a plurality of wooden legs radiating from a vertically disposed column.

Plural leg supports, such as those commonly used as pedestals for tables or bases for chairs, are often formed with metal legs in order to provide the rigidity and strength required for the table or chair to be supported by such support, however, as est hetically pleasing as some metal legs may be they still cannot equal the esthetic beauty of a well formed natural wooden leg.

Existing supports utilizing a plurality of natural wood legs radiating from a vertical post, in many cases, present a cumbersome appearance since the wooden legs must be formed with bulky dimensions in order to provide the rigidity and strength required to support the article disposed thereon and/or whatever is to be carried by such article. In addition, some presently known methods and mechanisms for interconnecting a plurality of legs about a central hub are complex, costly, difficult to assemble, and quite often do not provide the rigidity required for a proper support.

It is therefore an object of this invention to provide an improved support.

It is a further object to provide an improved support having a plurality of wooden legs extending from a central hub.

A still further object is to provide an improved support hub adapted to receive and properly position a plurality of radially disposed wooden legs and a vertical post.

Another object is to provide an improved support hub which is relatively inexpensive to fabricate, simple to use, and which securely and rigidly receives and interconnects a plurality of wooden legs and a post to thus form a support for a chair, table, or the like.

Still another object is to provide an improved construction for a wooden leg adapting same to receive a rolling caster or a glide.

Still another object is to provide an improved wooden leg construction upon which either a rolling caster or a glide may be disposed proximate the extreme end of the leg without fracturing or otherwise damaging same.

This invention involves plural leg supports of the type used for chair bases, table bases, and the like, wherein a plurality of wooden legs extend radially from a centrally disposed vertical post or pedestal, and contemplates providing a tubular hub member adapted to carry leg mounting structure of -U-shaped configuration, with one leg of the -U adapted to be embedded within the leg in such 3,443,782 Patented May 13, 1969 a manner that the leg is securely gripped or even pinched between the legs of the U-shaped mounting structure.

In carrying out the invention, according to preferred embodiment thereof, the support is formed from a substantially square, vertically disposed, hollow, tubular, hub member, with a pair of spaced flat arms extending from each wall of the tube upon which a leg is to be mounted. The flat arms are formed as the arms of a substantially U-shaped leg support which is mounted on the hub with one of the flat arms extending from an aperture formed therein and the other arm extending out proximate the bottom edge of the hub. Each leg is formed with an aperture adapting same to fit over the arm which extends from the aperture in the hub and so that a bottom surface of the leg lies adjacent the lower arm of th U-shaped leg support member. Suitable apertures or holes are formed in both arms of the 'U-shaped leg support, and in the leg, to permit securing members, in the form of screws or bolts, to be threaded between the arms of the leg support to pull the arms towards each other and squeeze the wood of the leg t-herebetween; thus forming a secure support for the leg. In addition, there is disposed proximate the free end of the leg a flat plate recessed into the material of the wood, and having an aperture which is either threaded to receive the threaded shank of a glide member, or adapted to carry a tubular hearing which in turn will receive the pin of a rolling wheel or caster.

Other objects, features, and advantages of the invention in its details of construction and arrangement of parts, will be seen from the above, from the following description of the preferred embodiment when considered in conjunction with the drawings, and from the appended claims.

For convenience, the invention will be described as applied to a support of the type used as a base for a chair, table, or the like; it being understood nevertheless, that, without departing from the scope of this invention, that subject support may be utilized for any other item requiring a plural leg support such as a coat rack, display rack, or the like, and which are to be provided with a plurality of wooden legs radially projecting from a centrally disposed hub and which are adapted to have disposed thereon casters or glides.

With reference to FIG. 1 there is generally shown at a support of the type commonly used as a base for swivel chairs and the like and consisting of four wooden legs 22 radially extending from a hub member 24 (FIGS. 1 and 2) and mounting casters 26 (FIGS. 1 and 7). A bearing member 30 is received within hub 24 and, in turn, receives a post 34 carried by a swivel chair or the like An aperture (FIG. 3) of substantially rectangular configuration is formed in each wall 42 (FIGS. 2 and 4) of hub member 24, and is adapted to receive an upper arm (FIGS. 4 and S) of a substantially U-shaped leg attaching bracket 52. A lower arm 54, interconnected to upper arm 50 of bracket 52 by a cross-piece 56, is adapted for disposition adjacent a lower edge (FIG. 4) of hub 24.

A plug 64 (FIG. 4) in the form of either a hollow or solid cylindrical member may be inserted in a space 66 remaining within hub member 24 after U-shaped brackets 52 are disposed therein as shown in FIGS. 2 and 4. In the alternative U-shaped brackets 52 may be tack welded together as at 68 (FIG. 3) or otherwise secured in place on hub 24.

A pair of apertures 72 (FIG. 5), formed in each upper arm 50 of brackets 52, and a pair of apertures 74, formed in each lower arm 54 of brackets 52, are: adapted to receive threaded securing members 76 (FIG. 4) in the form of bolts or screws. Apertures 72 may either be threaded, or securing members 76 formed with threads which will thread the apertures when members 76 are threaded therethrough. Another pair of apertures 78 (FIG. 5) are formed in each lower arm 54 to receive securing members 80 in the form of wood screws.

A longitudinal bore 86 (FIGS. 4 and 6) of appropriate configuration is formed in each leg 22 to receive upper arm 50 of U-shaped bracket 52, and a pair of transverse bores 88 (FIGS. 4 and 6) are formed in each leg 22 to receive threaded securing members 76.

To assemble leg members 22, U-shaped brackets 52, and hub 24, into a unitary support, one need only mount an appropriate number of U-shaped brackets 52 on hub 24 by inserting upper arms 50 thereof through apertures 40 of hub 24 so that lower arms 54 thereof rest against lower edge 60 of hub 24, and then secure same in place with either a plug 64, by tack welding as at 68, or by other suitable means. Legs 22 are then slipped in place so that upper arm 50, of bracket 52, is disposed within longitudinal bore 86 against the inner wall 90 (FIGS. 4 and 6) thereof and so that a lower surface 92 of leg 22 rests upon an upper surface 94 (FIG. 5) of lower arm 54 of bracket 52. Threaded securing members 76 are then threaded into place and tightened up so that a portion 96 of leg 22 between upper arm 50 and lower arm 54 of bracket 52 is squeezed therebetween. One or more screws 80 are then tapped into leg 22 as the final securing step for support 20.

If desired, a cap member 98 (FIG. 3) formed with an appropriate aperture to receive bearing member 30 may be placed over the top of hub member 24.

A toe plate (FIGS. 7 and 9) disposed in a shallow 112 (FIG. 7) of leg 22 and secured in place by a pair of wood screws 114 (FIG. 7), mounts a bearing 116 adapted for disposition in a bore 118 of leg 22 and is adapted to receive the pintle 120 of caster 26. A pair of apertures 124 (FIGS. 8 and 9) are formed in top plate 110 to facilitate the securing thereof to leg 22 by wood screws 114 (FIG. 7). The use of plate 110 and bearing 116 permits the disposition of caster 26 proximate an end 128 (FIG. 7) of leg 22 without pintle 120 of caster 26 breaking through end 128 as is commonly experienced in many existing supports for wooden legs.

Although hub 24 has been shown as a tube of substantially square cross section, it should be obvious that hub 24 may be in the form of a tubular member of rectangular, circular, triangular, or other convenient cross section or for that matter as a solid member. In addition, although hub 24 has been shown with only a short vertical rise it may be formed with any desired vertical rise to facilitate the use thereof as a support for an item of furniture such as a table (FIG. 10).

A pair of tubular hubs 142 of triangular corss section are vertically extended to form columns 144 upon which table top 146 of table 140 is supported. A pair of legs 22' extend from and are supported upon each hub 142; said legs 22 being secured thereto by appropriately formed bracket members, such as bracket members 52 of FIG. 5, and in the same manner, that legs 22 are secured to hub 24 in FIGS. 1 and 4.

A stretcher 150, spanning hubs 142, is secured thereto by the use of bracket members, such as bracket members 52, in the same manner that legs 22 and 22' are secured to bracket members 52.

A glide 152 (FIGS. 10 and 11), having a threaded shank 154 (FIG. 11) is threaded into a toe plate 156 (FIGS. 12 and 13) secured to the free end 128 of legs 22 by wood screws 158 (FIG. 11). Toe plate 156 is similar to toe plate 110 of FIG. 9 but formed with a threaded aperture 160 (FIG. 12) to receive shank 154 of glide 152.

It should be obvious that either casters 26 or glides 152 may be disposed on legs 22, 22'.

FIGS. 6 and 14 show a modified form of the leg attaching construction with FIGS. 1-5 utilizing hub 24 having formed in the walls thereof substantially square apertures 40' (FIG. 6) each adapted to receive an upper arm in the form of a hollow tubular member and which is secured thereto by welding as at 172, or by other suitable means. An inner end 174 of upper arm 170 extends through aperture 40' of hub 24 and into an aperture 176 (FIG. 6) of a vertically disposed portion (FIGS. 6 and 14) of a lower arm 180. The lower arms 180 are secured in place, as shown in FIG. 14, by disposing in a space 182 therebetween bearing member 30, or other suitable means such as a plug similar to plug 64 of FIG. 4. It is of course understood that arms 180 may be secured in place by welding or other suitable means.

An internally threaded T-nut 188 is disposed in each aperture 190 formed in upper arm 170.

With upper arm 170 and lower arm 180 in place on hub 24', legs 22 may be secured thereon by merely slipping same over upper arms 170 in such a manner as to place arms 170 within bores 86 of legs 22. Threaded securing means 194 are then inserted through apertures 196 formed in lower arms 180, through transverse bores 88 of legs 22, and into T-nuts 188 carried by upper arms 170. Threaded members 194 are then tightened up sufiiciently to effect a tight gripping or pinching of portions 96 of legs 22 disposed between upper arms 170 and lower arms 180.

In FIG. 15 a hub 24" is shown extending upwardly into a vertical column 210 upon which a table, such as table 140, a chair or any other item may be disposed. An upper arm 214, in the form of a solid cylindrical bar, with an inner end 216 thereof extending through an aperture appropriately formed in hub 24" is secured to the wall of hub 24" by welding as at 218, or by other suitable means. Inner end 216 of upper attaching arm 214 is also received in an aperture 220 formed in a vertically extending portion 224 of a lower arm 226.

When lower arms 226 are in place on inner ends 216 of upper arms 214 the assembly is completed by inserting a plug 64 of appropriate circular configuration in the space therebetween. Any other suitable means of securing may be used such as welding, etc., if desired.

With upper arms 214 and lower arms 216 properly secured the hub 24", legs 22" may be secured thereto by slipping upper arms 214 into bores 86" of legs 22" and by inserting lower arms 226 into a hollowed out portion 230 formed in a lower surface 92" of legs 22'. Threaded attaching members 234 may then be inserted through apertures appropriately formed in lower arms 226 and through bores in legs 22" to be secured to upper arms 214 by either threading same into tapped holes provided therein or into T-nuts which may be carried thereby. Threaded members 234 are then tightened up so that portions 96" of legs 22" between lower arms 226 and upper arms 214 are tightly gripped if not even pinched between upper arms 214 and lower arms 226.

From the above description, it will thus be seen that a novel and improved support has been provided for chairs, tables, and the like which permits the attachment of wooden legs to a centrally disposed hub in such a manner that the legs need not be bulky and may be inexpensively, easily and securely attached to the hub, and which further permits the disposition proximate the ends of the wooden legs of casters, rollers, or gliders without the stems thereof rupturing the ends of the wooden legs.
