Definitions
- FIG 3 m m H mm M 0v H v r 4 0 M 3 N- f m M g y w I ⁇ &r6 4
- the support particularly visualized by the invention is of that category commonly referred to as spiders in which a plurality of spaced legs radiate in the manner of wheel spokes from a central arbor or hub on or in which there may be engaged a post such as a tree trunk.
- the support or spider more particularly visualized by the invention is formed of parts which are disassemblable and re-assemblable for storage and use, respectively.
- a spider as herein contemplated requires to assume reasonably rigid characteristics when assembled in order that it may thereby be enabled to maintain the post in a relatively steady condition.
- easy assembly and disassembly is also an obviously important desideratum of the contemplated spider supports.
- the aforesaid desiderate were not ordinarily incorporated in prior devices particularly those designed to retail at popular prices. That is to say, the said prior devices were either lacking the requisite rigidity or, in the alternative, were difiicult to assemble and disassemble; having been deliberately rendered so in an effort to achieve steadiness by reducing tolerances to tighten the interfitting of the parts.
- the invention accordingly, seeks to provide a spider support as described which is relatively easy to assemble and disassemble, which provides a steady, stable support when assembled, and whose design permits it to be manufactured inexpensively-cg: of plastics.
- an important object of the invention is to provide a spider support in a design which lends itself to construction of plastic material, e.g.: Polyethylene, and which is capable of yielding an economical yet sturdy and smoothly functioning product comprising a hub and spoke elements which lend themselves to easy assembly as a spider support and are equally easily disassembled for storage; the spider, in this assembled state, providing sturdy and stable support for its load.
- plastic material e.g.: Polyethylene
- the hub preferably includes in its construction, a receptacle for a post as aforesaid; a fence surrounding said receptacle in spaced relation thereto, and spaced slots in said fence.
- said spoke elements are preferably equipped with anchors removably installable in said slots; abutments engaging said fence when the anchors are installed in the slots, and channels between the anchors and the abutments; the aforesaid slots presenting edges which are receivable in said channels when the anchors are installed in the slots as aforesaid, and which are clampable therein to impart stability to the resulting structure.
- FIG. 1 is a perspective view of the present support with a formalized tree supported thereby;
- FIG. 2 is a side elevational view of a spoke
- FIG. 3 is a sectional view along line 33 of FIG. 5 with a standard positioned in the receptacle;
- FIG. 4 is a bottom plan view showing a spoke in posi tion on the hub
- FIG. 5 is an isometric view of the hub with part of one spoke secured thereto and another in alignment with a slot in the hub for positioning.
- spider support S will be seen to comprise a pluralitythree, in this instance-of leg elements hereinafter conveniently termed spokes R which radiate in the manner of wheel spokes from a central hub H which is interengageable with post 2 constituted in this case by the trunk of an artificial tree T, installed Within a receptacle provided as said hub H.
- said hub H will be deemed to be in its upright position in FIG. 3 whereby, it will be observed, that receptacle 4 aforesaid is provided with a [floor 6 through which post 2 installed in receptacle 4 as aforesaid is fixed therein by a screw 7.
- receptacle 4 must have sufficient depth to provide reasonably secure accommodation for the lower end of the post 2 installed therein. In ordinary circumstances, two or three inches Will constitute sufficient depth for this purpose; this being, then, also the general overall height of the hub H.
- Said hub H further includes a fence 8 of relatively thin stock having a width which is also commensurate with the depth of the receptacle 4 and which surrounds the latter in spaced and generally co-axial relation therewith.
- Said fence 8 is also coterminous with the receptacle 4 and its upper edge is integrally connected thereto by a fillet 10 at the top of hub H which forms a base or ceiling, as the case may be, for trench 112 between the receptacle and the fence.
- Said fence 8 is provided with a number of axial slots 14 in each of which a spoke R is installable in the manner to be described. As shown, each said slot 14 depends from a point slightly below fillet 10 to the lower, free edge of fence 8 at which said slot 14 is open to entry.
- the said spoke R is suitably elongated to afford requisite stability to spider S and is oifset at one end, which may be of reduced cross-section as shown, to form a foot 30.
- the said spoke R is preferably widened to match the height of the hub H and its abutting end is shaped conformingly to fence 8 and will be noted in FIGS. 4 and 5 so as to be capable of mating therewith.
- the fence 8 being cylindrical in the present embodiment, the aforesaid widened end of spoke R is arched to match the curvature thereof thus forming a mating abutment 32 therefor in which nests the abutting portion of fence 8.
- the height of said abutment 32 approximates the height of hub H while its thickness exceeds the width of slot 14 so that, when placed thereover in abutting relation to fence 8, it will overlap the aforesaid slot edges 2020.
- An anchor A attached to and extending forwardly from spoke R is installable in a slot 14 to secure said spoke R to said hub H in radial and fairly rigid relation thereto.
- Said anchor A includes a shank 34 which extends forwardly from abutment 32 in the manner of a fin and is thin enough to enter the slot 14 and tall enough to fill it. It is desirable, however, that the shank thickness be suffi ciently less than the slot width to render said shank 34 freely slidable in said slot 14 when the anchor is installed therein except as hereinafter noted.
- the forward projection of shank 34 into trench 12 is such as to permit the fence 8 to nest in abutment 32 as shown in FIG. 4 when said shank 34 is installed in slot 14.
- Said shank 34 is capped by an angular formation providing a thin and relatively flexible wing 38 integrally attached to shank end 36 on each side thereof and flaring rearwardly therefrom so that, when the latter is installed in a slot 14, the said wings 3838 will engage the fence 8 on each slide of slot 14 in the interior of trench 12.
- each said channel 40 receives a slot edge 20 when the anchors are installed in the hub with said slot edges clamped between the anchors and the abutments providing a reasonably rigid assembly.
- Said slot edges are of a thickness less than channels 49 and therefore are relatively freely slidable in the channels during installation of the anchors in the slots and before the clamping of the slot edges which does not occur until each anchor is almost completely installed in its slot.
- the lower portion of each channel 40 as viewed in the upright spoke position of FIG.
- the parts are so dimensioned and proportioned as to permit relatively unimpeded movement of shank 34 in slot 14 and slot edges 2020 in channels 40-40 until such time as the upper portion of the anchor enters the narrowed trench zone Z and the wing tip embossments constricting channel 40 initially engage the fence.
- spoke R is in its final assembled position.
- the upper portion of the anchor A is in the narrowed zone Z and is wedged therein between the receptacle 4 and fence 8.
- the embossment 43 and the abutment 32 co-operate to provide a clamping effect on fence 8 inasmuch as the thickness of the fence exceeds the constricted width of the channel between the e-mbossment and abutment prior to assembly.
- a spider support for supporting a standard comprising:
- said hub including,
- a receptacle for holding a standard in an upright position
- spoke elements including,
- the said slots presenting edges receivable in said channels when the anchors are installed therein as aforesaid with said edges clamped between the anchors and the abutments providing a rigid assembly;
- said wings cooperating with said abutments to define the channels aforesaid.
- said trench has a narrowed zone within which the said wings are wedged between the receptacle and the fence.
- said clamping References Cited means and the narrowed zone of said trench being UNITED STATES PATENTS respectively disposed to procure clamping of the slot edges and wedging of said wings only when the 1,422,933 7/1922 DFmYOH 248 188-7 anchors have been substantially completely installed 5 2,855,168 10/1958 Vlgna- 248-48 in said 510% 2,609,169 9/ 1952 Kroeger 24848 4.
- a spider support as set forth in claim 2 including 1 717142 6/1929 Bump 248188-7 a top integrally connecting the receptacle and the fence, 3,078,063 2/1963 Frankl 248188-7 the slots extending from the bottom of the fence to a point below its top.
- a spider support as set forth in claim 3 including: webs joining the fence and the receptacle between said slots.
