SUPPORT STAND FOR POLE-LIKE OBJECTS
BAC~GROUND OF THE INVENTION
The present invention is directed to a support stand, and it particularly relates to stands which are adapted for releasea~ly retaining pole-l;ke objects in a supported upright position on a support surface. Thus, the present invention contemplates a support stand for such o~jects as banner poles, flag poles, real and artificial Christmas trees, rally markers and the like.
It is particularly useful in cooperation with a support structure for ~anners.
The use of pole-like supports fGr message displays, advertising displays for the support of national and regional flags, and as a support for banners and flags that represent groups, such as sport teams, delegations and the like are becoming ; 15 increasingly more popular. Use of such structures is highly desired for both indoor and outdoor functions.
Where a support pole requires a temporary mount rather than a permanent mount, it is desira~le to ha~e a sturdy yet compact support stand which may readily be assembled and disassembled as use o~ the support pole requires.
This need is felt both where the support pole is a single integral unit and where it is a collapsi~le pole structure.

Prior art support stands for pole-like objects have included stands of a perm~nent nature as weLl as some porta~le stands. Permanently affixed stands include tubular pipes which are embedded in the ground or which are implanted in concrete hases that are either embedded in the ground or permanently affixed to another support surface. Other stands may, for all practical purposes, be considered permanent due to their physical mass since they are not readily mov~a~le; again, these include, for example, cast concrete blocks. Other permanent stands include risid metallic brackets that may be bolted to a support surface, such as a sidewalk, plaza and the like.
On the other hand, temporary stands for portable pole-like objects found in the prior art include the traditional Christmas tree stand wherein a plurality of radially outwardly projecting legs may be attached by screws to a cup-like container adapted to receive the stump of a Christmas tree. Artificial Christmas trees have a smaller hase which may be telescopically received in a tubular base support. Also, temporary support stands include those having a plurality of folding legs attached to slide brackets with these legs being scissor actuated to move from a stored position to a support position. There is a a new and improved stand with a ~;~ support pad abuts the support sur~ace and a plurality of ~: ~ leqs pivot downwardly to terminate in staked ends thatengage the ground or in support pads located at an offset relationship with respect to the central pad.

Despite these prior axt supports, -there remains a need for a support stand that may be disassembled into a stored position which readily and ea ily be assembled in a support coniguration to positively support a pole-like object on a support surface. There is a further need for such a support stand which may readily be used in indoor and outdoor applications and which may be adjustable to compensate for slight irregularities in the flatness of the support surface. There i~ a further need or a support stand which may be stored in a mini-mum amount of space and which may be used repeatedly over a course of time. There is a Eurther need for a support stand o simplified structure that requires minimum assembly time without the need for assembly tools.

DFTAILED DFSCRIPTION OF THE PREEERRED EMBODIMENT
The present invention is directed to support stands i~ general and speci~ically to a support stand for pole-like objects. The support stand according to the preferred embodiment oE the present inve~tion i5 particularly adapted as a stand which may be easily erected for use and disassembled for storage ~ithout the need for tools. As such, the present invention is constructed to be particularly useful as a support stand for supporting pole like objects on a generally horizon-tal support surface. Such objects include flag poles, banner poles, artificial and real Christmas trees, and other pole-like objects. Thus, it should be understood that the scope of this invention contemplates the supporting of any object that has a lower shank portion that may be mounted in a stand so that the object is held in an upright position.
Turning to the Figures, the preferred embodiment of the present invention is best shown in Figures through 3. ~ere, support stand 10 includes a base assem~ly 12 and intermediate leg assembly 14 and an upper leg a~sembly 16. Support atand 10 is used to ,, v ~ 7 ~3~59~63 support a pole-like object, as represented by pole 18 on a support su.rface such as surface 20. As is shown in Figures 1-3, base assernbly 1~. is formed by a base mem~er 22 in the form of a tube ha~ing an upwardly open mouth 24 having a surrounding upper rim 27. Mouth 24 is adapted to receive a lower shank portion 19 of pole 18 so that shank portion 19 is supported in the interior cavity 23 of base member 22. A lower portion of base member 22 is enlarged, and this is accomplished by having a lower portion o~ tube 26 telescopically received in and rigidly affixed to a base sleeve 28.
Thu~, it should be appreciated that base member 22 is formed by tube 26 and base sleeve 28 which are rigidly affixed to one another. A primary leg 30 is rigidly secured to base member 22. To this end, leg 30 has an upper leg portion 32 which is affixed to ~ase sleeve 28 such as by welding or other attachment means at location 34. Upper leg portion 32 is oriented longitudinally of the base member in spaced parallel relation to the outer surface thereof, as is ~est shown in Figure 3.
Accordingly, a gap 36 is formed between outer portion and the surface of tube 22~ with gap 36 having a radial width slightly greater than the radial thickness of the base sleeve 28 and mounting sleeves 42 and 56, discussed below. Leg 30 extends downwardly from upper leg portion 32 and is outwardly divergent to form a main leg portion 38 which projects laterally away from the ~ase member and terminates at ~ree end 40 which is adapted to rest on sur~ace 20, as is shown in Figure 3. As noted above, .
:~3~5~;3 leg 30 is rigidly secured to sleeve 28 and to tube 26 which form base member 22. However, it i5 within the scope of this invention that leg 30 and sleeve 28 be affixed to one another as a leg assembly, similar to leg assemblies 14 and 16, and that this leg assem~ly be slideably mounted on the base assembly.
Intermediate leg assembly 14 is best shown in Figure 2 and includes a mounting sleeve 42 which has an inner sleeve surface 44 and an outer sleeve surface 46.
Sleeve 42 is sized to ~e slideably and mateably received on tube 26 of ba3e member 22 so that it is in close-fitted engagement therewith to define an enga~ed position. A second~ry leg 48 is rigidly mounted onto mounting sleeve 42 ~uch as ~y welding or other attachment means known in the art. Leg 4~ is identical in con~truction with leg 30 so that it has an upper leg portion 50 and a main leg portion 52 which extends downwardly from and projects laterally away from base member 22 ln the nested position. Leg 48 terminates at a free end 54 which will engage the support surface 20.
Likewise, upper le~ assembly 16 includes a mounting sleeve 56 having an inner sleeve surface 58 and an outer sleeve surface 60. A secondary leg 62 has an upper leg portion 64 which is rigidly secured to mounting sleeve 56, again by welding or other attachment technique.
Sleeve 56 is sized to be slideably and mataably received on tube 26 of base member 22 in the engaged position.
Leg 62 includes a main leg portion 66 which extends downwardly and laterally outwardly of base member 22 in g ,, ,~ ~ .
, the engaged position so that it terminates in a free end 68 that engage~ mounting surface 20.
It should be apprecia~ed from the foregoing that the construction of leg assem~lies 14 and 16 are substantially the same and, indeed, are quite compara~le to the con~truction o~ ~ase assem~ly 12. As may be seen in Figure 2, base sleeve ?.8 of base mem~er 22 is identical with each of sleeves 42 ~nd 56 and receives smaller diameter tu~e 26 therein. Since each of upper leg portions 32, 50 and 64 are oriented longitudinally at the base mem~er in the nested position, sleeves 42 and 56 slide onto tu~e 26 ~o that they are completely nested on base member 22 between tu~e 26 and upper leg portion 32 of leg 30. In order to present a uniEorm appearance, sleeve 56 is mounted on the uppermost end of upper leg portion 64 of leg 62. Sleeve 42 is then mounted downwardly on upper portion 50 of leg 48 a distar.ce e~ual to the longitudinal length of sleeve 56.
Similarly, sleeve 28 is mounted onto upper portion 32 or leg 30 a distance e~ual to the com~ined longitudinal lengths o~ sleeves 56 and 42. Thus, when in the engaged position shown in Figure 1, the upper ends of legs 30, 48 and 62 are in a com~on plane trans~er~e to the longi ;~ tudinal axis of tube 26. Each of sleeves 42 and 56 are then nested within ~ap 36 between tube 26 and upper leg portion 32 of leg 30.
In order to prevent relative angular rotation of sleeves 42 and 56 and, correspondingly, legs 48 and 62, angular registration and retaining structure is .

.
;
~3~PS~3 provided. As is best shown in E'igure 2, sleeve 28 of base member 22 is provided with radiAlly outwardly pro-jectin~ nubs 70 and 72 which are spaced with respect to each other and to upper leg portion 32 eq~iangularly about sleeve 28. Each of legs 30, 48 and 62 are formed as bent U-shaped channel pieces so th~t upper leg portions 32, 50 and 64, respectively, are formed as radially inwardly opening channel pieces. Thus, for example, as sleeve 42 i5 slid onto tube 46, upper leg portion 50 is oriented so that the inwardly opening channel of upper leg portion 50 slidingly engages nub 70. Similarly, as mounting sleeve 56 is slid onto tu~e 26, thè inwardly openi~g channel o~ upper leg portion 64 slideably engages nub 72. The engagement of nu~s 70 and 72, respectively, with the channels in upper leg portions 50 and 64 prevent rotation of base assem~ly 12, intermediate leg assembly 14 and upper leg assembly 15 about a longitudinal axis.
: It can further be appreciated from the foregoing that tube 26 is si~ed so that it has an upper rim 27 which is in a ~ommon plane with upper ends 33, 51 and 65 of leg portions 32, 50 and 64, respectively. Thus, when in the nested position, mouth 24 is in the common plane of the upper ends of each of the support legs. The common internal radius and external radius of each of the mounting sleeves 42 and 56 as well as base sleeve 28 thus pre 5 ent a uniform cylindrical appearance for base member 22, as best shown in Figure 1.
As noted above, pole 18 has a lower shank portion 19 that is received throu~h mouth 24 into the interior , ~3~S~63 of tube 26. To further positîon pole l8 on support stand 10, a positioning sleeve 21 is telescopically received onco pole 18 and is affixed thereto. I,ower shank portion 19 thus comprises a smaller diameter tu~e that is telescopically received in tu~e 18 and affixed thereto. Since tube 19 is sized to be telescopically received on the interior of tube 26, tube 26 has a similar diameter with pole 18. Sleeve 21 thus has a common diameter with sleeves 28, 42 and 56 so that pole 18 may be telescapically received into mounting stand 10. Thus, it should be appreciated that tubular pole 18 can he used as an adapter to receive a flagstaff or other elongated pole-like mem~er.
As is seen in Figures 1 through 3, and also in Figure 4, each of legs 30, 48 and 62 are provided with holes at their respective free ends. Specifically, free end 40 of leg 30 is provided with an upwardly opening hole 41, free end 54 of leg 48 is provided with upwardly opening hole 55, and free end 68 of leg 62 is provided ~ith upwardly opening hole 69. Each of these holes is provided to either receive a mounting stake or adjustin~
pad. By way of example, in Figure 4, leg 62 is shown adapted to receive a stake 80 which may ~e pl~ced through hole 69 and driven into the support surface.
This is especially useful for outdoor use where it is desired to ~urther secure mounting stand 10 to the ground. Where the stand 10 is used on a floor, pole 69 could receive a nail, bolt or other mounting element to secure leg 62 onto the 100r. Such mounting structure would be then used for each o~ holes 41, 55, and 6~.
,, ~. , ~ .
:
~ .
~3(~Sa~63 Alternately, an adjustable pad structure may be providecl. As is shown in Figure 5, ~y way of example and not limitation, a threade~ bolt 82 may be provided and positioned upwardly into hole 69. Bolt 82 nas a lower support pad 84, a threaded shank 86 which extends through hol~ 62 to terminate at a threaded upper end 88 which threada~ly receives a nut 90 thereon. Leg 62 is connected to bolt and nut assem~ly 8~,90 so that, as nut 90 i5 rotated, free end 68 of leg 62 moves upw~rdly and downwardly. Thus, this assembly provides a position adjust~ent between the free ends o~ each of the legs in the support surface so as to compensate for a sli~htly irregular support surface 20.
In operation, then, a user assembles support stand 1~ 10 by first mounting intermediate leg assembly 14 on ~ase assembly 12 by telescopically engaging tube 26 with sleeve 42 with nub 70 engaging the channel on upper leg portion 50 of leg 48. When this engagemant i5 com-pleted, the user next takes upper leg assem~ly 16 and slideably mounts sleeve 56 in telescopic relation onto tube 26 with the channel of upper leg portion 64 engaging nub 72, This assembly may then be placed on support surface 20 and pole 18 may be mounted therein by placins tube 19 through mouth 24 so that lower leg portion 19 engages the interior of tube 26. Each of legs 30, 48 and 6~. are slightly flexible and are curved at a large radius from its respective free end to a mid-portion thereof. Thusj as is shown in Figure 3, leg 3a ~; extends at a gently sloping curve at a large radius from .
3i4~
free end 4G to a location adjacent its attachmen-t point 34. Thus, a mid-portion of leg 30 is oriented at acute angle 0 with respect to support surface 20 that is engaged by free end 40. Sinc~ leg 30 is slightly flexible, the weight of any pole-like object pla~ed in support stand 10 will allow support stand 10 to flex and therefore automatically accommodate slight irregulari-ties in the support sur~ace. Further, it should be appreciated that the use of three legs for the support assembly is desired since Eree ends 40, 54 and 68 deEine a plane for suppoxt stand 10 as the three engaged points. However, any number of leg assemblies are contemplated within the scope of this invention. Since the free ends of each le~ engage the support surface at a laterally offset location, the weight of the base member and the supported object create a bending moment on each leg that helps bind each mounting sleeve against longitudinal movement.
Turning to the modifications oE the present invention, ~urther mountin~ structure is shown in Figure 6. Here, support stand 110 is constructed almost identically with support stand 10, described above.
However, as is shown in Figure 6, each upper leg portion 132, 150 and 164 o~ legs 130, 148 and 162 terminate at upper ends 133, 151 and 165, respectively. Again these upper en~s are in a common plane. Howe~er, the trans-, verse plane of upper ends 133, 151 and 165 is spaced above rim 127 50 that each upper leg portion 132, lS0 and 164 extends above the open mouth 124 o~ base assembly 112. Each o~ these upper leg portions is then ~ 14 :~ :
, ' ~3~S~;3 provided with a threaded hole that receives adjusting wingheaded ~olts 180 which may be advanced in the threaded hole in a radial direction. Thus, when a pole-like object is inserted into support stand 10, threaded ~olts 180 may be operated to positively engage the pole assembly to Eu~ther retain the pole assembly in release--able connection to the support stand llO. This embodiment is particularly usef~l as a support stand for an artificial Christmas -tree.
As is shown in Figures 7 and $, base assembly 10 may be employed with an adapted base 100. Base 100 includes a lower shank 102 which is sized to telescopi-cally fit through mouth 24 of base mem~er 20. A CUp-shaped receptacle 104 has an interior cavity 106 which has an enlarged diameter and which is sealed by plate 108 at its lower portion. A plurality of threaded bolts 109 extend through holes such as threaded hole 107 so that bolts 109 are radially advanced into and out of cavity 106. It should be appreciated that when adapter base 110 is mounted on support stand 10 a pole-like ob~ect having an enlarged base portion may be mounted onto the stand. This adapter is particularly useful for live Christmas trees so that, af~er the trunk of the tree is placed within ca-~ity 106, bolts 109 are ti~htened to secure the tree therein. Water may then be added into receptacle 104 as is known in the art.
Naturally, virtually any adapter base having a lower shank portion is within the scope o~ this invention.
An alternate embodiment of the support stand according to the present invention is shown in Fi~ure 9.
~L3~ Ei3 Here, a support stand 210 is shown having a base assembly 212 that is s~uare-shaped in cross-~ection so that a hollow square twbe 226 replaces tube 26 of base assembly 12. Square-shaped sleeves 228, 230, 232 and 234 extend around tube 226 with square sleeve 228 pre~erably being rigidly ~ecured thereto in a manner similar to sleeve 28 oE the preferred emhodiment described above. Four tubular legs 236, 233, 240 and 242 have lo,ngitudinal leg portions such that the longi-tudinal le~ portions of legs 238, 240 and 242 are respectively attached to sleeves 230, 232 and 234. The mid-portion of legs 236, 238, 240 and 242 extend upwardly and downwardly to terminate, respectively, at free ends 256, 258, 260 and 262 that engage the support surface by pads 266, 268, 270 and 272. Each of the legs are fairly rigid ~ut flex slightly to again allow for modestly uneven support surfaces. The square confi~uration of tube 226 and sleeves 228, 230, 232 and 234 provide the angular alignment of the legs in an equiangular position. Other polygonal shapes ~or the ' hase member could be readily empl~yed.
Alternate embodiments of the equiangular alignment means are shown in Figure 10 and 11. In Figure 10, base assembly 312 includes a tube 326 that has a base sleeve 328 to which a leg 330 is attached. Intermediate leg assembly 314 includes a leg 348 that is attached to mounting sleeve 342, and upper leg assembly 316 has a leg 362 that i5 rigidly secured to a sleeve 356. As is shown in Figure 10, sleeve 328 i~ provided with a slot ~: .
.
: i .
~5463 329 and sleeve 342 is provided with a mating tab 341 that is si~ed to engage slot 3290 Thus, when sleeve 342 is positioned in telescopic nest~d position on tube 326, sleeve 342 may be rotated so that tab 341 engages slot ~29 to properly align intermediate leg a~sembly 314 with respect to rotational ansle. Si.milarly, then, sleeve 342 is provided with a ~lot 343, and sleeve 356 is provided with a tab 355 sized to engage slot 342. When sleeve 356 is nested onto 326, upper leg assem~ly 316 may be rotated 50 that tab 355 engages slot 342, thus aligning each of legs 330, 348 and 362 and eqlliangular positions about the longitudinal axis of the support stand 310.
In Figure 11, support stand 410 is provided with a ~ase member including a tube 426. Tube 426 has a plurality of equiangularly spaced ribs 428, and each sleeve, such as sleeve 456 is provided with a plurality of channels, such as channels 458, again at equiangularly spaced intervals around the inner surface of the mounting sleeve. Thus, when leg assemblies 414 and 416 are rotated with respect to base assembly 412, these channels and ribs mate to equian~ularly align the leg assemblies with respect to the base assembly a~out the longitudinal axis.
Accordin~ly, the present invention has ~een described with some degreP of particularity directed to the preferred embodiment of the preSQnt invention.

SUPPORT STAND FOR POLE-LIKE OBJECTS
BAC~GROUND OF THE INVENTION
The present invention is directed to a support stand, and it particularly relates to stands which are adapted for releasea~ly retaining pole-l;ke objects in a supported upright position on a support surface. Thus, the present invention contemplates a support stand for such o~jects as banner poles, flag poles, real and artificial Christmas trees, rally markers and the like.
It is particularly useful in cooperation with a support structure for ~anners.
The use of pole-like supports fGr message displays, advertising displays for the support of national and regional flags, and as a support for banners and flags that represent groups, such as sport teams, delegations and the like are becoming ; 15 increasingly more popular. Use of such structures is highly desired for both indoor and outdoor functions.
Where a support pole requires a temporary mount rather than a permanent mount, it is desira~le to ha~e a sturdy yet compact support stand which may readily be assembled and disassembled as use o~ the support pole requires.
This need is felt both where the support pole is a single integral unit and where it is a collapsi~le pole structure.

' - , ~;~QS46~
Prior art support stands for pole-like objects have included stands of a perm~nent nature as weLl as some porta~le stands. Permanently affixed stands include tubular pipes which are embedded in the ground or which are implanted in concrete hases that are either embedded in the ground or permanently affixed to another support surface. Other stands may, for all practical purposes, be considered permanent due to their physical mass since they are not readily mov~a~le; again, these include, for example, cast concrete blocks. Other permanent stands include risid metallic brackets that may be bolted to a support surface, such as a sidewalk, plaza and the like.
On the other hand, temporary stands for portable pole-like objects found in the prior art include the traditional Christmas tree stand wherein a plurality of radially outwardly projecting legs may be attached by screws to a cup-like container adapted to receive the stump of a Christmas tree. Artificial Christmas trees have a smaller hase which may be telescopically received in a tubular base support. Also, temporary support stands include those having a plurality of folding legs attached to slide brackets with these legs being scissor actuated to move from a stored position to a support position. There is a a new and improved stand with a ~;~ support pad abuts the support sur~ace and a plurality of ~: ~ leqs pivot downwardly to terminate in staked ends thatengage the ground or in support pads located at an offset relationship with respect to the central pad.

DFTAILED DFSCRIPTION OF THE PREEERRED EMBODIMENT
The present invention is directed to support stands i~ general and speci~ically to a support stand for pole-like objects. The support stand according to the preferred embodiment oE the present inve~tion i5 particularly adapted as a stand which may be easily erected for use and disassembled for storage ~ithout the need for tools. As such, the present invention is constructed to be particularly useful as a support stand for supporting pole like objects on a generally horizon-tal support surface. Such objects include flag poles, banner poles, artificial and real Christmas trees, and other pole-like objects. Thus, it should be understood that the scope of this invention contemplates the supporting of any object that has a lower shank portion that may be mounted in a stand so that the object is held in an upright position.
Turning to the Figures, the preferred embodiment of the present invention is best shown in Figures through 3. ~ere, support stand 10 includes a base assem~ly 12 and intermediate leg assembly 14 and an upper leg a~sembly 16. Support atand 10 is used to ,, v ~ 7 ~3~59~63 support a pole-like object, as represented by pole 18 on a support su.rface such as surface 20. As is shown in Figures 1-3, base assernbly 1~. is formed by a base mem~er 22 in the form of a tube ha~ing an upwardly open mouth 24 having a surrounding upper rim 27. Mouth 24 is adapted to receive a lower shank portion 19 of pole 18 so that shank portion 19 is supported in the interior cavity 23 of base member 22. A lower portion of base member 22 is enlarged, and this is accomplished by having a lower portion o~ tube 26 telescopically received in and rigidly affixed to a base sleeve 28.
Thu~, it should be appreciated that base member 22 is formed by tube 26 and base sleeve 28 which are rigidly affixed to one another. A primary leg 30 is rigidly secured to base member 22. To this end, leg 30 has an upper leg portion 32 which is affixed to ~ase sleeve 28 such as by welding or other attachment means at location 34. Upper leg portion 32 is oriented longitudinally of the base member in spaced parallel relation to the outer surface thereof, as is ~est shown in Figure 3.
Accordingly, a gap 36 is formed between outer portion and the surface of tube 22~ with gap 36 having a radial width slightly greater than the radial thickness of the base sleeve 28 and mounting sleeves 42 and 56, discussed below. Leg 30 extends downwardly from upper leg portion 32 and is outwardly divergent to form a main leg portion 38 which projects laterally away from the ~ase member and terminates at ~ree end 40 which is adapted to rest on sur~ace 20, as is shown in Figure 3. As noted above, .
:~3~5~;3 leg 30 is rigidly secured to sleeve 28 and to tube 26 which form base member 22. However, it i5 within the scope of this invention that leg 30 and sleeve 28 be affixed to one another as a leg assembly, similar to leg assemblies 14 and 16, and that this leg assem~ly be slideably mounted on the base assembly.
Intermediate leg assembly 14 is best shown in Figure 2 and includes a mounting sleeve 42 which has an inner sleeve surface 44 and an outer sleeve surface 46.
Sleeve 42 is sized to ~e slideably and mateably received on tube 26 of ba3e member 22 so that it is in close-fitted engagement therewith to define an enga~ed position. A second~ry leg 48 is rigidly mounted onto mounting sleeve 42 ~uch as ~y welding or other attachment means known in the art. Leg 4~ is identical in con~truction with leg 30 so that it has an upper leg portion 50 and a main leg portion 52 which extends downwardly from and projects laterally away from base member 22 ln the nested position. Leg 48 terminates at a free end 54 which will engage the support surface 20.
Likewise, upper le~ assembly 16 includes a mounting sleeve 56 having an inner sleeve surface 58 and an outer sleeve surface 60. A secondary leg 62 has an upper leg portion 64 which is rigidly secured to mounting sleeve 56, again by welding or other attachment technique.
Sleeve 56 is sized to be slideably and mataably received on tube 26 of base member 22 in the engaged position.
Leg 62 includes a main leg portion 66 which extends downwardly and laterally outwardly of base member 22 in g ,, ,~ ~ .
, the engaged position so that it terminates in a free end 68 that engage~ mounting surface 20.
It should be apprecia~ed from the foregoing that the construction of leg assem~lies 14 and 16 are substantially the same and, indeed, are quite compara~le to the con~truction o~ ~ase assem~ly 12. As may be seen in Figure 2, base sleeve ?.8 of base mem~er 22 is identical with each of sleeves 42 ~nd 56 and receives smaller diameter tu~e 26 therein. Since each of upper leg portions 32, 50 and 64 are oriented longitudinally at the base mem~er in the nested position, sleeves 42 and 56 slide onto tu~e 26 ~o that they are completely nested on base member 22 between tu~e 26 and upper leg portion 32 of leg 30. In order to present a uniEorm appearance, sleeve 56 is mounted on the uppermost end of upper leg portion 64 of leg 62. Sleeve 42 is then mounted downwardly on upper portion 50 of leg 48 a distar.ce e~ual to the longitudinal length of sleeve 56.
Similarly, sleeve 28 is mounted onto upper portion 32 or leg 30 a distance e~ual to the com~ined longitudinal lengths o~ sleeves 56 and 42. Thus, when in the engaged position shown in Figure 1, the upper ends of legs 30, 48 and 62 are in a com~on plane trans~er~e to the longi ;~ tudinal axis of tube 26. Each of sleeves 42 and 56 are then nested within ~ap 36 between tube 26 and upper leg portion 32 of leg 30.
In order to prevent relative angular rotation of sleeves 42 and 56 and, correspondingly, legs 48 and 62, angular registration and retaining structure is .
::
.
;
~3~PS~3 provided. As is best shown in E'igure 2, sleeve 28 of base member 22 is provided with radiAlly outwardly pro-jectin~ nubs 70 and 72 which are spaced with respect to each other and to upper leg portion 32 eq~iangularly about sleeve 28. Each of legs 30, 48 and 62 are formed as bent U-shaped channel pieces so th~t upper leg portions 32, 50 and 64, respectively, are formed as radially inwardly opening channel pieces. Thus, for example, as sleeve 42 i5 slid onto tube 46, upper leg portion 50 is oriented so that the inwardly opening channel of upper leg portion 50 slidingly engages nub 70. Similarly, as mounting sleeve 56 is slid onto tu~e 26, thè inwardly openi~g channel o~ upper leg portion 64 slideably engages nub 72. The engagement of nu~s 70 and 72, respectively, with the channels in upper leg portions 50 and 64 prevent rotation of base assem~ly 12, intermediate leg assembly 14 and upper leg assembly 15 about a longitudinal axis.
: It can further be appreciated from the foregoing that tube 26 is si~ed so that it has an upper rim 27 which is in a ~ommon plane with upper ends 33, 51 and 65 of leg portions 32, 50 and 64, respectively. Thus, when in the nested position, mouth 24 is in the common plane of the upper ends of each of the support legs. The common internal radius and external radius of each of the mounting sleeves 42 and 56 as well as base sleeve 28 thus pre 5 ent a uniform cylindrical appearance for base member 22, as best shown in Figure 1.
As noted above, pole 18 has a lower shank portion 19 that is received throu~h mouth 24 into the interior , ~3~S~63 of tube 26. To further positîon pole l8 on support stand 10, a positioning sleeve 21 is telescopically received onco pole 18 and is affixed thereto. I,ower shank portion 19 thus comprises a smaller diameter tu~e that is telescopically received in tu~e 18 and affixed thereto. Since tube 19 is sized to be telescopically received on the interior of tube 26, tube 26 has a similar diameter with pole 18. Sleeve 21 thus has a common diameter with sleeves 28, 42 and 56 so that pole 18 may be telescapically received into mounting stand 10. Thus, it should be appreciated that tubular pole 18 can he used as an adapter to receive a flagstaff or other elongated pole-like mem~er.
As is seen in Figures 1 through 3, and also in Figure 4, each of legs 30, 48 and 62 are provided with holes at their respective free ends. Specifically, free end 40 of leg 30 is provided with an upwardly opening hole 41, free end 54 of leg 48 is provided with upwardly opening hole 55, and free end 68 of leg 62 is provided ~ith upwardly opening hole 69. Each of these holes is provided to either receive a mounting stake or adjustin~
pad. By way of example, in Figure 4, leg 62 is shown adapted to receive a stake 80 which may ~e pl~ced through hole 69 and driven into the support surface.
This is especially useful for outdoor use where it is desired to ~urther secure mounting stand 10 to the ground. Where the stand 10 is used on a floor, pole 69 could receive a nail, bolt or other mounting element to secure leg 62 onto the 100r. Such mounting structure would be then used for each o~ holes 41, 55, and 6~.
,, ~. , ~ .
:
~ .
~3(~Sa~63 Alternately, an adjustable pad structure may be providecl. As is shown in Figure 5, ~y way of example and not limitation, a threade~ bolt 82 may be provided and positioned upwardly into hole 69. Bolt 82 nas a lower support pad 84, a threaded shank 86 which extends through hol~ 62 to terminate at a threaded upper end 88 which threada~ly receives a nut 90 thereon. Leg 62 is connected to bolt and nut assem~ly 8~,90 so that, as nut 90 i5 rotated, free end 68 of leg 62 moves upw~rdly and downwardly. Thus, this assembly provides a position adjust~ent between the free ends o~ each of the legs in the support surface so as to compensate for a sli~htly irregular support surface 20.
In operation, then, a user assembles support stand 1~ 10 by first mounting intermediate leg assembly 14 on ~ase assembly 12 by telescopically engaging tube 26 with sleeve 42 with nub 70 engaging the channel on upper leg portion 50 of leg 48. When this engagemant i5 com-pleted, the user next takes upper leg assem~ly 16 and slideably mounts sleeve 56 in telescopic relation onto tube 26 with the channel of upper leg portion 64 engaging nub 72, This assembly may then be placed on support surface 20 and pole 18 may be mounted therein by placins tube 19 through mouth 24 so that lower leg portion 19 engages the interior of tube 26. Each of legs 30, 48 and 6~. are slightly flexible and are curved at a large radius from its respective free end to a mid-portion thereof. Thusj as is shown in Figure 3, leg 3a ~; extends at a gently sloping curve at a large radius from .
3i4~
free end 4G to a location adjacent its attachmen-t point 34. Thus, a mid-portion of leg 30 is oriented at acute angle 0 with respect to support surface 20 that is engaged by free end 40. Sinc~ leg 30 is slightly flexible, the weight of any pole-like object pla~ed in support stand 10 will allow support stand 10 to flex and therefore automatically accommodate slight irregulari-ties in the support sur~ace. Further, it should be appreciated that the use of three legs for the support assembly is desired since Eree ends 40, 54 and 68 deEine a plane for suppoxt stand 10 as the three engaged points. However, any number of leg assemblies are contemplated within the scope of this invention. Since the free ends of each le~ engage the support surface at a laterally offset location, the weight of the base member and the supported object create a bending moment on each leg that helps bind each mounting sleeve against longitudinal movement.
Turning to the modifications oE the present invention, ~urther mountin~ structure is shown in Figure 6. Here, support stand 110 is constructed almost identically with support stand 10, described above.
However, as is shown in Figure 6, each upper leg portion 132, 150 and 164 o~ legs 130, 148 and 162 terminate at upper ends 133, 151 and 165, respectively. Again these upper en~s are in a common plane. Howe~er, the trans-, verse plane of upper ends 133, 151 and 165 is spaced above rim 127 50 that each upper leg portion 132, lS0 and 164 extends above the open mouth 124 o~ base assembly 112. Each o~ these upper leg portions is then ~ 14 :~ :
, ' ~3~S~;3 provided with a threaded hole that receives adjusting wingheaded ~olts 180 which may be advanced in the threaded hole in a radial direction. Thus, when a pole-like object is inserted into support stand 10, threaded ~olts 180 may be operated to positively engage the pole assembly to Eu~ther retain the pole assembly in release--able connection to the support stand llO. This embodiment is particularly usef~l as a support stand for an artificial Christmas -tree.
As is shown in Figures 7 and $, base assembly 10 may be employed with an adapted base 100. Base 100 includes a lower shank 102 which is sized to telescopi-cally fit through mouth 24 of base mem~er 20. A CUp-shaped receptacle 104 has an interior cavity 106 which has an enlarged diameter and which is sealed by plate 108 at its lower portion. A plurality of threaded bolts 109 extend through holes such as threaded hole 107 so that bolts 109 are radially advanced into and out of cavity 106. It should be appreciated that when adapter base 110 is mounted on support stand 10 a pole-like ob~ect having an enlarged base portion may be mounted onto the stand. This adapter is particularly useful for live Christmas trees so that, af~er the trunk of the tree is placed within ca-~ity 106, bolts 109 are ti~htened to secure the tree therein. Water may then be added into receptacle 104 as is known in the art.
Naturally, virtually any adapter base having a lower shank portion is within the scope o~ this invention.
An alternate embodiment of the support stand according to the present invention is shown in Fi~ure 9.
~L3~ Ei3 Here, a support stand 210 is shown having a base assembly 212 that is s~uare-shaped in cross-~ection so that a hollow square twbe 226 replaces tube 26 of base assembly 12. Square-shaped sleeves 228, 230, 232 and 234 extend around tube 226 with square sleeve 228 pre~erably being rigidly ~ecured thereto in a manner similar to sleeve 28 oE the preferred emhodiment described above. Four tubular legs 236, 233, 240 and 242 have lo,ngitudinal leg portions such that the longi-tudinal le~ portions of legs 238, 240 and 242 are respectively attached to sleeves 230, 232 and 234. The mid-portion of legs 236, 238, 240 and 242 extend upwardly and downwardly to terminate, respectively, at free ends 256, 258, 260 and 262 that engage the support surface by pads 266, 268, 270 and 272. Each of the legs are fairly rigid ~ut flex slightly to again allow for modestly uneven support surfaces. The square confi~uration of tube 226 and sleeves 228, 230, 232 and 234 provide the angular alignment of the legs in an equiangular position. Other polygonal shapes ~or the ' hase member could be readily empl~yed.
Alternate embodiments of the equiangular alignment means are shown in Figure 10 and 11. In Figure 10, base assembly 312 includes a tube 326 that has a base sleeve 328 to which a leg 330 is attached. Intermediate leg assembly 314 includes a leg 348 that is attached to mounting sleeve 342, and upper leg assembly 316 has a leg 362 that i5 rigidly secured to a sleeve 356. As is shown in Figure 10, sleeve 328 i~ provided with a slot ~: .
.
: i .
~5463 329 and sleeve 342 is provided with a mating tab 341 that is si~ed to engage slot 3290 Thus, when sleeve 342 is positioned in telescopic nest~d position on tube 326, sleeve 342 may be rotated so that tab 341 engages slot ~29 to properly align intermediate leg a~sembly 314 with respect to rotational ansle. Si.milarly, then, sleeve 342 is provided with a ~lot 343, and sleeve 356 is provided with a tab 355 sized to engage slot 342. When sleeve 356 is nested onto 326, upper leg assem~ly 316 may be rotated 50 that tab 355 engages slot 342, thus aligning each of legs 330, 348 and 362 and eqlliangular positions about the longitudinal axis of the support stand 310.
In Figure 11, support stand 410 is provided with a ~ase member including a tube 426. Tube 426 has a plurality of equiangularly spaced ribs 428, and each sleeve, such as sleeve 456 is provided with a plurality of channels, such as channels 458, again at equiangularly spaced intervals around the inner surface of the mounting sleeve. Thus, when leg assemblies 414 and 416 are rotated with respect to base assembly 412, these channels and ribs mate to equian~ularly align the leg assemblies with respect to the base assembly a~out the longitudinal axis.
Accordin~ly, the present invention has ~een described with some degreP of particularity directed to the preferred embodiment of the preSQnt invention.
