Description

FIELD OF THE INVENTION
The present invention relates to receptacles serving as trash can holders and plant pots mainly used on city streets.
BAC~CGROUyD OF THE INVENTION
Trash cans as used on city streets are generally removably supported in a holder which is itself either fixedly mounted on a stand fixed to the sidewalk surface or attached to a lamp post, or the like, so that the trash can can be eaqily removed and emptied by city employees. Such holders are often subjected to damage, especially in citieb located in northern climates where snow-clearing equipment is used during the winter-time. Such equipment including narrow endless track vehicles equipped with a front-mounted snow plow adapted to travel on sidewalks; such vehicles often hit the trash can holders. Such holders are often made of steel straps with or without spaced upright wood slats, and thus can be easily de$ormed or broken by the snow plows.
Considerable upkeep expenses are therefore incurred by the city admini~tration. The same remarks apply to plant pots such as flower pot~ and tree pots which are usually made metal or o~ glass fiber rein~orced resins.
OBJECTS OF THE INVENTION
~t is therefore the general object of the present invention to provide a trash can holder and a plant pot which have a considerably improved resistance to damage ~rom colliding vehicles.

,'"

~78~13 Another object of the present invention is to provide a trash can holder of the character described, so supported as to be transversely shiftable and rotatable upon impact by a moving objeat or vehicle, so as to decrease or absorb the impact shock to a de~ree sufficient to avoid damage to the holder.
Another object of the pre~ent invention is to provide a trash can holder and a plant pot of the character described, using - a flexible, resilient sheet of elastomeric material as a side wall to form a shock-absorbent surface and also to form a wall which will have a very long useful life and which ha~ decorative characteristics.
- SUMMARY OF THE INVENTION
; The side wall of the trash can holder and plant pot of ; the invention is preferably formed by a transversely-bent flexible ;~ 15 resilient sheet, made of elastomeric material, preferably reclaimed rubber as obtained from used automobile tires. The sheet is bent ; into a cylindrical shape, with ad~acent parallel edge portions disposed upwardly, the lower edge of the cylindrical wall rests on a bottom closure plate and retaining means are fixed to the bottom closure plate to retain the sheet in the cylindrical shape.
-~ The retaining means for retaining the sheet in its cylindrical shape preferably include an upright member, of H-qhaped cross-section, fixed to and upstanding from said bottom closure plate at the periphery of the latter, 3aid member defining oppositely-directed channel~, each receiving and guiding one of the two parallel edge portions of the sheet. The retaining means ~: ' ,'' ' ' .

- ~ ~ 7 ~

: preferably further includes circular bands or straps fixed to said H-shaped member and located at vertically-spaced zones along the latter, said bands surrounding the circular wall, the lowest band fixed to the periphery of said bottom closure plate and upwardly protruding therefrom. Preferably, the lowest band also protrudes downwardly from said bottom closure to provide a good grasp for a workman wishing to transport the holder. When the ~-shaped upright member i3 used for the holder, it, preferably has a cross-leg formed by two spaced wall portions defining a third channel opening at the suter face of the cylindrical wall, so that a conventional stake , of T-shaped cross-section, can have its main leg fitted within said third channel with the stake attached to the H-shaped member and driven into the ground to keep the holder in vertical position.
The holder also has a stand, adapted to be fixed onto a . ~upporting surface, which includes an upright stem and a top plate fixed to the upper end of said stem, the bottom closure plate resting on the top plate and transversely shiftable and rotatable -~ relative to the latter. The holder iEurther includes confining means secured to the under~ide of the bottom closure plate and underlapping the underside of the top plate of the stand to prevent tilting of said bottom closure plate and, consequently, of said side wall with respect to said upright stem. The confining means . preferably includes a collar fixed to and protruding from the ; 25 under~ide of the bottom closure plate and an annular flange fixed to and radially inwardly extending from said collar and parallel to '' ' ' "
,, . ~.

, 2~7~13 and spaced from said bottom closure plate a distance about equal to ; the thickness of said top plate of said stand. The annular flange defines a circular opening co~axial with the bottom closure plate and of a diameter greater than but less than the diameter of said top plate, said collar having a diameter greater than that of said top plate, the latter extending between said bottom closure plate and said flange and said upright stem extending through said circular opening. This arrangement allows, as indicated above, transverse shifting and rotation of the cylindrical wall relative to the base upon an impact received by the cylindrical wall to thus decrease and absorb the shock imparted to the holder, resulting in the avoidance of damage ts the latter. Preferably, the bottom closure plate has drainage openings for any liquid which may accumulate in the holder and said openings can be brought into vertical register with the screw-receiving holes made in the bottom plate of the base, so that a screwing tool extending within the cylindrical wall and accessible to workmen at the top of the cylindrical wall, can be made to reach screws and the screw holes, ~- so as to screw and unscrew the same from the top of the holder.

, DETAILED DESCRIPTION OF THE INVENTION
The trash can holder of the invention is shown in Figure 1 and comprises a resilient, flexible sheet 10, of elastomeric material, preferably reclaimed rubber as obtained from used vehicle ; 5 2~7~3 tires. The sheet 10 may have a thickne~s between one-half inch and .~ one inch and it has a rectangular shape when laid flat.
The sheet 10 is maintained in curved, cylindrioal shape with its adjacent edge portions lOA (see Figure 4) maintained : 5 vertical and in close relationship by means of an upright sheet metal member 12, of H~shaped cross-section, which defines . oppositely-directed channels 14 in which the marginal edge portions ;~ lOA of the sheet 10 are inserted and guided. As shown in Figure 4, ` upright member 12 is preferably made of two strips of sheet metal, namely: an inner strip 16 transversely curved in accordance with the radius of curvature of the sheet 10, and an outer strip 18 also ~. transversely curved and which also transversely aurved and is : centrally longitudinally depressed to form a third channel 20, which opens outwardly of the holder. The portion o~ the outer strip forming the third channel 20 includes a channel bottom 22 which i~ welded or otherwise .~ecured to the central part of the inner strip 16 and two side walls 24 which are spaced apart and - correspond to the transverse leg of the H formed by upright member , ~
12.
The wall portions Eorming the third channel 20 serve to .. - , ~ reinforce the upright member 12 and also serve to receive the main : leg of a T-shaped stake, of conventional construation, not shown, which may be driven into the ground to hold the holder in upright position, the stake being secured by flexible strapping to the upright member 12.
Rigid sheet metal bands or straps 26, 28, and 30 are ::

, secured as by welding to the outer ends of the outer strip 18 at - vertically-spaced zones along the upright member 12. The straps 26, 28, and 30 form three rings, of a diameter such as to frictionally engage the outside of the sheet 10 and further retain the same in cylindrical shape. The upper s$rap 26 extends just below the upper edge of the sheet 10; the intermediate strap 28 ' extends at about the mid-height of the sh~et 10; and the lower : strap 30 is preferably wider than the two upper straps and surround ' the bottom portion of the sheet 10. A vertical strip 32 10 interconnects the three straps 26, 28, and 30 at zones thereof " diametrically opposite the upright member 12. Strip 32 maintains the three straps 26, 28, 30 in their intended horizontal position.
A bottom closure plate 34, of circular shape, is secured as by spot welding at its periphery to the bottom strap 30 along a zone such that the strap 3~ projects not only upwardly from the bottom closure plate to surround sheet 10, as shown in Figure 3, but also protrudes do~nwardly from closure plate 34, so . ~
as to provide a grasp for a workman to better easily transport the trash can holdler.
The closure pl,ate 34 is secured within the lowsr strap 30 in such an orientation that its peripheral notch 36 be in re~ister with the third channel 20 of the upright member 12. A second dish-shaped circular plate 38 is secured to the underside of the closure plate 34 It has the same diameter as the latter and is also provided with a notch 40 in alignment with the notch 36 of plate 34. Second plate 38 can be defined by a collar 41 from the lower 2~78~3 edge o$ which radially, inwardly extends an annular flange 42 and from the upper edge of which radially, outwardly extends an upper annular flange 44. In an alternate embodiment, the upper flange 44 could be dispensed with, with the top edge of collar 42 directly secured to the underside of the closure plate 34. The latter, ; together with the lower flange 42, are spaced apart and form a ;~ cavity 46 in which is slidably received the top plate 48 of a stand 47 compri~ing a base plate 50 and an intermediate tubular stem 52.
The top plate 48 and the base plate 50 are secured in spaced parallel relationship to the top and bottom end of the stem 52, respectively. ~
Collar 41 and top plate 48 have preferably a circular ~ -shape. Annular flange 42 defines a circular central opening 54, through which stem 52 extends. The top plate 48 is located within cavity 46 in frictionally-slidable contact with the underside of the bottom closure plate 34 and the top side of the lower flange 42. The diameter of top plate 48 is greater than the diameter of central opening 54, but less than the diameter of collar 41, so that the top plate cannot be removed from its engagement within cavity 46, but the closure plate 34 and, consequently, the entire trash can holder is free to be laterally shifted and rotated relative to the top plate 48, while the holder remains in upright position.
In the embodiment shown in Figure 3, the lateral shifting of the closure plate relative to the ~tand 47 is stopped when stem 52 makes contact with the edge of the central opening 54.

2 ~ 3 The above-noted arrangement whereby the cylindrical wall 10, together with bottom closure plate 34 with the assembly of the upright member 12 and straps 26, 28, 30, can be bodily rotated and/or shifted upon impact with respect to stand 47, has been found to greatly diminish damage to the trash can holder which might be caused by an impact of a motorized snow-plow or the like. The shock is absorbed due to the lateral shifting which is usually comb1ned with a rotation oE the above-noted asssmbly with respect to the stand 47, due to the fact that in most cases, the resultant of the impact is laterally offset with respect to the vertical axis of the trash can holder. The arrangement is such that the holder is always maintained in upright position, since the depth of the - cavity 46 is substantially equal to the thickness of the top plate 48. Usually a snow plow hits the holder at the level of lowest lS strap 30 or just above. Normally, the cylindrical trash can A, which is inserted within and removed from the holder by means of its handles ~, as shown in Figure 2, is provided with drainage - openings C, such openings avoiding any accumulation of liquid, such as rain, within the can A. In the same manner, the bottom closure plate 34, together wit~ the upper flange 44, are provided with drainage openings 56, 56a to drain any liquid out of the holder.
-Base plate 50 is normally rectangular in shape and provided at its four corners with holes 58 for receiving screws 60 used to fix the base plate 50 onto a supporting surface, such as a sidewalk D.
In accordance with a feature of the invention, the ' i~ . .

2~7~ 3 drainage openings 56, made in plates 34, 38, arP disposed so that they may be brought into vertical register with the base plate holes 58, so that a suitable tool may be inserted by the workman through the open end of the holder through the drainage openings 56, 56a so as to gain access to the screws 60 within the holes 58, so as to screw the same into the sidewalk surface In the same manner, the screws 60 may be removed. This permits city workmen to more conveniently fix and remove the holder to and from the sidewalk. Obviously, this operation i5 made with the trash can A
out of the holder.
Referring to Figures 7 to 9, it is seen that the trash can holder without the stand 47 can be directly secured to a lamp post E or the like by means of flexible steel straps F, which - surround the post and extend, as shown in Figure 9, through slots made in the walls 24 of the outer strip 18 of the upright member 12, and on the outside of the edge portions 10A of the sheet 10.
Straps F are clipped together at their ends by means of standard ; clips, not shown. Obviously, the compl,ete trash holder, including .. ~'--'.
its stand, as shown in Figure 1, could be secured in the same manner to a lamp post 8 or the like, with the base plate 50 of the stand directly on the ground.
; Figure 8 shows also that the vertical edges 10A of the sheet 10 can be in the form of a cut-out, so as to enable the vertical edge portions lOC of the sheet above the upright member 12 to be close together.
Figures 10 to 14 relate to a receptacle used as a plant , .

~ 2~7~:L3 pot to be installed on city ~treets to hold young trees or flowers.
~- The pot 70 is cylindrical and its diameter is preferably about 36"
with a height of about 27". In the example shown two ~lexible, resilient sheet~ 72 of equal size are used together with an equal number oE upright members 74 of H-shaped cross-section. Sheets 70 are preferably made of reclaimed rubber such as sheet 10. Their vertical edge portions 72a are inserted and retained within channels 76 defined by members 74. Sheets 72 may have vertical slots 78. Pot 70 has a bottom closure plate 79 on which rest the curved sheets 72. Plate 79 has water draining hole 80. Rigid, sheet metal, horizontal bands 82, 84 and 85 retain and surround sheets 72 and are secured to the outside of upright members 74.
Lowermost band 86 surrounds and is secured to the periphery of closure plate 79 and projects downwardly therefrom. Ground engaging legs 88 are secured to closure plate 79 and band or ring 86. A sheet metal cylindrical liner 90 is applied against the inside face of sheets 72 and is secured at its bottom edge to closure plate 79 as by welding. Preferably a heat insulating layer 92 of foam plastic coats the inside face of liner 90. The pot is filled with earth and the plant roots are protected against sudden temperature drops by layer 92. As an alternative, liner 90 and layer 92 are replaced by sheets of reclaimed rubber such as ~heets 72 but thicker and without slots 78. Such sheets will provide good heat inqulation and together with sheet 72, the necessary strength to contain the earth. Such plant pots are heavy and are lifted by a power crane the hooks of which engage eyes 94 in the form of bent ~ 2~7~3L3 - -,`` , -.
