Components suitable for use and reuse to hang receptacles, for example, planters.
Description
~2Z948~
This invention relates to components suitable for use and reuse to hang receptacles, for example, planters.
BACKGROUND OF INVENTION
Many approaches have been taken to the hanging of planters.
They have been secured by macrame, ropes, chains and the like and sup-penned from hooks fastened to the ceiling.
These approaches, however, each have the disadvantage that their distance from the ceiling cannot be easily adjusted. In most instances the material is knotted to provide some degree of adjustment.
However the degree of adjustment is approximate. Additionally, the adjustment is unsightly.
It is therefore an object of this invention to provide come pennants suitable for use to hang planters.
It is a further object of this invention to provide components to hang planters which permit easy adjustment of the distance the planter is suspended from the support (for example, the ceiling).
It is a further object of this invention to provide for such adjustment without special tools, or complex or unsightly adjustments.
In many instances, it is desired to suspend planters without any apertures slots or slits in their body. In those instances, the means of suspending the planter must safely and attractively envelope the planter in such a way to permit secure suspension. Therefore, the means for suspension must carry a seat substantially of the same size as the bottom or base of the planter with the sides of the means of sup-pension engaging the sides of the planter to securely and attractively hold the planter. If the means of suspension is not the right size -the planter will not be securely and/or attractively suspended.
It is therefore an object of this invention to provide an improved means for suspending a planter which does not require the use ~294~34 1 of holes, slits, slots, tabs or protrusions or other means of modifying the planter to securely yet attractively suspend the planter.
Further and other objects of the invention will be realized by those skilled in the art from the following summary of the invention and detailed description of the preferred embodiments thereof.
SUMMARY OF INVENTION
According to one aspect of the invention, a hanger support suitable for use in hanging a receptacle (for example, a planter) or other items (such as sign age) is provided, the support comprising:
(1) a hanger from which the support may be secured to hang a receptacle (planter), or other item from, for example, a hook in the ceiling, the hanger having:
(a) a plane or zone disposed or oriented in the vertical direction when the hanger support is secured or suspended for hanging for example, a planter, and, (b) a position whereat the hanger would be supported when the support is used to hang a planter,
This invention relates to components suitable for use and reuse to hang receptacles, for example, planters.

SUMMARY OF INVENTION
According to one aspect of the invention, a hanger support suitable for use in hanging a receptacle (for example, a planter) or other items (such as sign age) is provided, the support comprising:
(1) a hanger from which the support may be secured to hang a receptacle (planter), or other item from, for example, a hook in the ceiling, the hanger having:
(a) a plane or zone disposed or oriented in the vertical direction when the hanger support is secured or suspended for hanging for example, a planter, and, (b) a position whereat the hanger would be supported when the support is used to hang a planter,
(2) a take-up spool having an endless channel defined between a spool (preferably cylindrical spool) and a pair of preferably radially extending walls extending from either end of the spool, the take-up spool secured to the hanger for taking up material (for example, cables for example nylon-coated kink-resistant stainless steel cable , wire, plastic strands, or the like) for supporting the planter or other item, the take-up spool incorporating a plane or zone disposed in the vertical direction when the hanger support is secured or suspended for hanging the planter, or other item, and
(3) a lock vertically below the spool and hanger offset to the plane or zone of the take-up spool but in vertical alignment with the plane or zone of the hanger, to cause material extending downwardly from the spool to be offset relative to the plane or zone of the spool and into lZi~948~
1 the vertical plane or zone of the hanger and in vertical alignment with the position in the hanger whereat the hanger would be supported to support the hanger support whereby there exists neither rotational forces exerted about the hanger causing the spool to rotate about the hanger nor forces tending to cause the spool to tilt out of a vertical plane or zone.
In this way, excess material carried in the hanger support may be wound-up and stored to permit alteration of the vertical position of the receptacle (for example, planter) or reuse with another receptacle as required. Furthermore, this support lends itself to use with small diameter cables and support means which facilitate the display of planters and plants contained therein without visual conflict with the means of suspension. This hanger support structure also finds use to hang other items for display purposes which require length adjustment, such as sign age.
In one embodiment the lock incorporates a vertically extending slot (when the support is hung) offset to the plane or zone of the take-up spool and vertically aligned with the plane or zone of the hanger, to assist to lock the material to extend vertically offset from the plane or zone of the take-up spool.
In another embodiment, the lock comprises an L-shaped struck lure extending below the take-up spool, the L-shaped structure comprising a pair of spaced flanges extending laterally from the structure (preferably at the bottom thereof), the L-shaped structure carrying a slot between the spaced flanges offset relative to the plane or zone of the take-up spool but aligned with the plane or zone of the hanger to permit material from ; the spool to pass through the slot and be locked thereby to hang vertically therefrom.
According to another aspect of the invention, the take-up spool is rotatable about a vertical axis relative to the hanger. In one ~2Z9~84 1 embodiment the take-up spool is rigidly fixed relative to the lock so that the lock, and, in the embodiment where the lock incorporates the slot, the slot, are each offset relative to the zone or plane of the take-up spool but in vertical alignment with the plane or zone of the hanger.
According to another aspect of the invention, the take-up spool may carry an aperture through the spool surface around which the material is wound to permit material passed through the aperture to be tied, knotted and/or covered by a brass fitting (eyelet) and/or, crimped to secure the material behind the surface. Therefore, where the length of the material is to be adjusted (shortened for example), more material can be pulled through the aperture and for example, tied or knotted behind the aperture to preclude the pulled through material from returning to the take-up spool until for example, the knot is untied. Where the take-up spool is rotatable about a vertical axis relative to the hanger, a pin may be fixed in one of the radially extending walls of the take-up spool and passed through a portion of the hanger permitting relative rotation of the pin and thus the take-up spool relative to the hanger.
A cap may be used to cover the pin to secure the pin to the hanger.
The support may be used to carry material (for example, nylon covered kink-resistant stainless steel cable) used to secure and suspend a planter in the manner disclosed in my Canadian Application Serial Number 372,031 and in United States Patent Application Serial Number 126,663 in which Applications a receptacle or container (e.g. a planter) having an outer surface and bowl shaped recess is provided for carrying a plurality of tabulate bodies or protrusions equally spaced about the planter, each tabulate body or protrusion presenting a face on the side of the body remote the outer surface of the planter and being carried by the planter proximate its rim, each tabulate body or protrusion carrying a slot intermediate

In another embodiment, the lock comprises an L-shaped struck lure extending below the take-up spool, the L-shaped structure comprising a pair of spaced flanges extending laterally from the structure (preferably at the bottom thereof), the L-shaped structure carrying a slot between the spaced flanges offset relative to the plane or zone of the take-up spool but aligned with the plane or zone of the hanger to permit material from ; the spool to pass through the slot and be locked thereby to hang vertically therefrom.
According to another aspect of the invention, the take-up spool is rotatable about a vertical axis relative to the hanger. In one ~2Z9~84 1 embodiment the take-up spool is rigidly fixed relative to the lock so that the lock, and, in the embodiment where the lock incorporates the slot, the slot, are each offset relative to the zone or plane of the take-up spool but in vertical alignment with the plane or zone of the hanger.
According to another aspect of the invention, the take-up spool may carry an aperture through the spool surface around which the material is wound to permit material passed through the aperture to be tied, knotted and/or covered by a brass fitting (eyelet) and/or, crimped to secure the material behind the surface. Therefore, where the length of the material is to be adjusted (shortened for example), more material can be pulled through the aperture and for example, tied or knotted behind the aperture to preclude the pulled through material from returning to the take-up spool until for example, the knot is untied.

DETAILED DESCRIPTION OF THE DRAWINGS
With reference to Figures 1 to 5 inclusive, hanger support 20 is provided suitable for use in hanging a planter 22, support 20 come prosing:
(1) hanger 24 having a plane or zone 26 disposed or oriented in the : :
: ' ~;~Z~4~4 1 vertical direction (see Figures 2 and 4) when hanger support Z0 is secured or suspended for hanging planter 22 at point X whereat hanger 24 engages a support (for example a hook fastened to the ceiling).
(2) take-up spool 28 integrally injection molded of polycarbonate with hanger 24 for taking up three nylon coated kink-resistant stainless steel lines 30 wrapped around cylindrical spool 32 (see Figures 4 and 5) the sides of which are closed by walls 34 and 36 which extend radially from spool 32 to define endless line receiving channel 38 between the outer peripheral surface 40 of cylinder 32 and between walls 34 and 36, channel 38 of take-up spool 28 incorporating a plane or zone 42 (see Figures 4 and 5) disposed or oriented in the vertical direction when hanger 24 is secured or suspended for hanging planter 22, and, (3) L-shaped locking structure 44 integrally molded with take-up spool 28, offset to plane or zone 42 of take-up spool 28 but in vertical alignment with plane or zone 26 of hanger 24 and particularly the vertical plane passing through point X whereat hanger 24 engages a support (for example a hook fastened to the ceiling) not shown.
L-shaped structure 44 comprises connector 46 formed as an extension of wall 38 and includes channel, slot or groove 48 (formed in the face of connector 46) vertically aligned with point X (see Figure
5). Connector 46 at the lower end thereof is integrally molded to laterally extending spacer 50 in turn integrally molded to flange 52 (shaped like a finger) spaced from connector 46 by spacer 50. Channel, slot or groove 48 cuts through an edge portion of spacer 50 and flange 52 to permit lines 30 to pass between connector 46 and flange or finger 52 from spool 28 and abut spacer 50 as it is channeled by channel, slot or groove 48 from hanger support 20 see Figure 3). Therefore, as can be seen, the construction of hanger support 20 by offsetting hanger 24, channel 38 of take-up spool 28 and the L-shaped locking structure 44 in the manner described precludes hanger support 20 from laterally rotating lZ~948~
1 about point X to one side or from tilting or rotating about point X
either forwardly or rearwardly out of vertical plane when hanger support 20 is secured by lines 30 to planter 22 and secured to a support (not shown) which engages hanger 24 at point X.
To adjust the distance planter 22 is supported below hanger support 20, lines 30 need only be taken up (wound) or let out (unwound) from take-up spool 28. To secure lines 30 to take-up spool 28, lines 30 are wound together on cylindrical spool 32 after passing the ends through aperture 54 seen best in Figure 4 and 5) extending through surface 40 of cylinder 32 through the body of cylindrical spool 32 opening through inner radial surface 56 and crimping, covering or knotting them.
When adjustment of planter 22 up or down relative to hanger support 20 is required, the line 30 is wound together around spool 32 in channel 38. The radius of the cylinder (for example 3/8" [.96 cm]), will control the increments of adjustment available with hanger support (for example, approximately 3/4 I' or 1.92 cam adjustments for the lines at surface 40 of cylinder 32). If finer adjustment is required, the ends of line 30 projecting beyond inner radial surface 56 may be pulled through aperture 54 and the lines knotted or looped or clipped at 58 and the line rewound about spool 28.
To permit relative rotation about a vertical axis of hanger 24 relative to take-up spool 28, the two components may be separately molded and secured by a pin 60 fixedly embedded in wall 38 and secured through a hole 62 passing through hanger 24 vertically aligned with point X (see Figure 6). Because channel, slot or groove 48 is vertically aligned with point X see Figure 5 particularly), relative rotation of take-up spool 24 and hanger 20 is permitted without tilting of hanger 20 out of vertical or lateral rotation about point X (see Figure 7).
Hanger support 20 is shown in Figure 1 supporting receptacle 22 by the use of three lines 30 wound in take-up spool 28 and extending AYE
1 therefrom spread from cylindrical bead 62 to three separate places proximate rim 63 at which place, each line is secured. To this end the end of each line carries an upset, enlarged end or bead, or knot or the like. Each position carries a tabulate body or protrusion 64 of the construction shown in my Canadian Patent Application Serial Number 372,031 . Particularly each tabulate body or protrusion 64 is disposed proximate rim 63 and has face 66 on the side of body 64 remote the outer surface 67 of planter 22.
Each tabulate body or protrusion 64 carries vertically extending slot 68 intermediate body's 64 width from the top 70 of protrusion 64 and opening through the bottom and face 66, the portion of slot 68 opening through face 66 being less than the width of slot 68. Slot I comprises a wider slot portion or socket 72 at the upper end of slot 68 in communication with slot 68 and opening through face 66, the opening of socket 72 through the face 66 being the same as the opening of slot 68 through face 66. Slot 68 opens at the bottom into 3 channel, slot or groove 75 defined by bead 74 extending from face 66 beyond the periphery of body 64 spaced from outer surface 67 curvilinearly around body 64 to upper rim 70 and having means for example, bead 74 being thickened in places between surface 67 and bead 74 (e.g. at the rim 70) to reduce the width of mouth AYE leading into channel, slot or groove 75, to require flexor of each line 30 when pushed into mouth 74 past the thickened portions into channel, slot or groove 75 to thereby secure strand in channel, slot or groove 75. Therefore, when each line 30 is to be secured to each tabulate body 64, the upset knot or the like on the end of line 30 is inserted into socket 72, line 30 pushed through the opening in face 66 into slot 68 and into channel, slot or groove 75 past thickened portions AYE in mouth 74 to cause each line 30 to extend curvilinearly around body 64 and be secured in such position to support the receptacle 22.
AYE
1 With reference to Figures to 11 inclusive, hanger support 20 is used to support another receptacle 80 which carries no visible means for its support. In this regard, three lines 30 extend from each support 20 for spreading at bead 82, to secure receptacle 80 using metal hooks 84 each carrying loop 86 on its end. Each line is fastened to base 88 on which receptacle 80 seats, base 88 comprising horizontally extending annular support 90 (reinforced by connector 92) and annular skirt 94 secured to the periphery of annular base 88 and, sloped angularly downwardly away from base 90. Three pairs of spaced apertures 96 through skirt 94 are equally spaced from one another, each pair of apertures 96 comprising apertures AYE and 96B for permitting each of lines 30 to be brought behind skirt 94, through one of apertures 96 and returned through the other aperture. On the back side 94B of skirt 94 (see Figure 11) secured to both the underside 90B of annular support 90 and back side 94B of skirt 94B and extending between apertures AYE and 96B is curved spacer surface 98 against which line 30 abuts to prevent extreme wends in the line to prevent weakening of the line. The end of line 30 remote support hanger 20 is, prior to inserting through aperture 96, passed through loop 86 of hook 84, then passed through aperture AYE along surface 98 to aperture 96B, out aperture 96B and connected to loop 86 with the assistance of connector 100 by passing the line through con-nectar 100 around a portion of loop 86 and secured in connector 100.
Each hook 84 is then pulled upwardly and pulled over the rim of recap-lade (planter) 80 securely supporting receptacle 80 by support hanger 20. Particularly the weight of receptacle 80 on base 90 causes each hook 84 to be pulled tightly onto the rim of receptacle 80 (see Figure 8) maintaining receptacle 80 on base 90. Because three equally spaced pairs of apertures 96 have been employed for securing the three lines 30, lines 30 preclude receptacle 80 from falling from base 90 because of the disposition of the hooks 84 and supporting lines 30 at 120 degrees 12Z9~84 1 to one another.
With reference to Figures 9 and 10, each connector 100 comprises an injection molded part comprised of polycarbonate and carries slot 102 having width "w", height "h" and varying depth "d" opening through both upper end 104 and lower end 106. At each side edge of slot 102, air-cuter slot portions 108 and 110 are of greater depth "d" than inter-mediate slot portion 112 between portions 108 and 110, the depth "d" of slot portion 112 being less than the thickness of line 30, however the depth "d" of portions 108 and 110 being greater than line 30. Slot portion 110 has a wider slot portion or socket Lola extending from intermediate upper and lower ends 104 and 106, to end 106 where it opens. The end of line 30 carries bell-shaped metal member 114 carrying radially directed flange 116 at one end arid is secured through hole 120 in member 114 by the end of line 30 being knotted at 122 (see Figure 10). Member 114 is wider than slot 110 but narrower than slot portion Lola and is about the length of slot portion AYE to seat in socket AYE
and lock line 30 to connector 100.
With reference to Figure 12, another method of securing planter 80 to base 88' similarly constructed to base 88 is shown which employs only two hooks and two long lines secured to one hanger support (not shown). Particularly, base 88' carries two sets of well spaced aver-lures AYE and 124B on skirt 94' and a third aperture 126 intermediate apertures AYE and 124B. The reason for such spacing is to ensure the end portions of line 30 extending upwardly from base 88', portion AYE
and 30B, are spaced enough to hold the receptacle, along with hooks 84' secured to the rim of the receptacle (planter - not shown, from falling from base 88'. On the under surface of skirt 94' are curved spacer surfaces (not shown) between apertures 124B and 126, and AYE and 126, against which line 30 abuts, also to prevent extreme bends in the line to prevent weakening of the line. Therefore, as is apparent, a loop 86' ~229~34 1 Of material 30C carrying a hook extends through each aperture 126 with the continuation of the two ends of loop 86' extending through aperture 126 behind skirt 94' to abut the curved surfaces (not shown), with the end of loop 86' emanating from that portion between hook 84' and aperture 126 extending towards the aperture AYE or 124B remote the portion between hook 84' and aperture 126 from which it emanates. Therefore, portion 30C' closest aperture AYE (remote aperture 124B) 'crosses over' portion 30C" and extends to aperture 124B and portion 30C" closest aperture 124B (remote aperture AYE) 'crosses-over' portion 30C' and extends to aperture AYE, each abutting the curved surface (not shown) and, passing from behind skirt 94' through the respective aperture vertically to the support.
Therefore, any planter carried on base 88' is fully supported so that it cannot fall out when hooks 84' are applied to the planter's rim and prevented from falling by the loops of material 30C and hooks 84' and the widely spaced vertically extending portions AYE and 30B.
As many changes can be made to the embodiments without de-parting from the scope of the invention, it is intended that all matter contained herein be interpreted as illustrative of the invention and not in a limiting sense.
1 about point X to one side or from tilting or rotating about point X
either forwardly or rearwardly out of vertical plane when hanger support 20 is secured by lines 30 to planter 22 and secured to a support (not shown) which engages hanger 24 at point X.
To adjust the distance planter 22 is supported below hanger support 20, lines 30 need only be taken up (wound) or let out (unwound) from take-up spool 28. To secure lines 30 to take-up spool 28, lines 30 are wound together on cylindrical spool 32 after passing the ends through aperture 54 seen best in Figure 4 and 5) extending through surface 40 of cylinder 32 through the body of cylindrical spool 32 opening through inner radial surface 56 and crimping, covering or knotting them.
When adjustment of planter 22 up or down relative to hanger support 20 is required, the line 30 is wound together around spool 32 in channel 38. The radius of the cylinder (for example 3/8" [.96 cm]), will control the increments of adjustment available with hanger support (for example, approximately 3/4 I' or 1.92 cam adjustments for the lines at surface 40 of cylinder 32). If finer adjustment is required, the ends of line 30 projecting beyond inner radial surface 56 may be pulled through aperture 54 and the lines knotted or looped or clipped at 58 and the line rewound about spool 28.
To permit relative rotation about a vertical axis of hanger 24 relative to take-up spool 28, the two components may be separately molded and secured by a pin 60 fixedly embedded in wall 38 and secured through a hole 62 passing through hanger 24 vertically aligned with point X (see Figure 6). Because channel, slot or groove 48 is vertically aligned with point X see Figure 5 particularly), relative rotation of take-up spool 24 and hanger 20 is permitted without tilting of hanger 20 out of vertical or lateral rotation about point X (see Figure 7).
Hanger support 20 is shown in Figure 1 supporting receptacle 22 by the use of three lines 30 wound in take-up spool 28 and extending AYE
1 therefrom spread from cylindrical bead 62 to three separate places proximate rim 63 at which place, each line is secured. To this end the end of each line carries an upset, enlarged end or bead, or knot or the like. Each position carries a tabulate body or protrusion 64 of the construction shown in my Canadian Patent Application Serial Number 372,031 . Particularly each tabulate body or protrusion 64 is disposed proximate rim 63 and has face 66 on the side of body 64 remote the outer surface 67 of planter 22.
Each tabulate body or protrusion 64 carries vertically extending slot 68 intermediate body's 64 width from the top 70 of protrusion 64 and opening through the bottom and face 66, the portion of slot 68 opening through face 66 being less than the width of slot 68. Slot I comprises a wider slot portion or socket 72 at the upper end of slot 68 in communication with slot 68 and opening through face 66, the opening of socket 72 through the face 66 being the same as the opening of slot 68 through face 66. Slot 68 opens at the bottom into 3 channel, slot or groove 75 defined by bead 74 extending from face 66 beyond the periphery of body 64 spaced from outer surface 67 curvilinearly around body 64 to upper rim 70 and having means for example, bead 74 being thickened in places between surface 67 and bead 74 (e.g. at the rim 70) to reduce the width of mouth AYE leading into channel, slot or groove 75, to require flexor of each line 30 when pushed into mouth 74 past the thickened portions into channel, slot or groove 75 to thereby secure strand in channel, slot or groove 75. Therefore, when each line 30 is to be secured to each tabulate body 64, the upset knot or the like on the end of line 30 is inserted into socket 72, line 30 pushed through the opening in face 66 into slot 68 and into channel, slot or groove 75 past thickened portions AYE in mouth 74 to cause each line 30 to extend curvilinearly around body 64 and be secured in such position to support the receptacle 22.
AYE
1 With reference to Figures to 11 inclusive, hanger support 20 is used to support another receptacle 80 which carries no visible means for its support. In this regard, three lines 30 extend from each support 20 for spreading at bead 82, to secure receptacle 80 using metal hooks 84 each carrying loop 86 on its end. Each line is fastened to base 88 on which receptacle 80 seats, base 88 comprising horizontally extending annular support 90 (reinforced by connector 92) and annular skirt 94 secured to the periphery of annular base 88 and, sloped angularly downwardly away from base 90. Three pairs of spaced apertures 96 through skirt 94 are equally spaced from one another, each pair of apertures 96 comprising apertures AYE and 96B for permitting each of lines 30 to be brought behind skirt 94, through one of apertures 96 and returned through the other aperture. On the back side 94B of skirt 94 (see Figure 11) secured to both the underside 90B of annular support 90 and back side 94B of skirt 94B and extending between apertures AYE and 96B is curved spacer surface 98 against which line 30 abuts to prevent extreme wends in the line to prevent weakening of the line. The end of line 30 remote support hanger 20 is, prior to inserting through aperture 96, passed through loop 86 of hook 84, then passed through aperture AYE along surface 98 to aperture 96B, out aperture 96B and connected to loop 86 with the assistance of connector 100 by passing the line through con-nectar 100 around a portion of loop 86 and secured in connector 100.
Each hook 84 is then pulled upwardly and pulled over the rim of recap-lade (planter) 80 securely supporting receptacle 80 by support hanger 20. Particularly the weight of receptacle 80 on base 90 causes each hook 84 to be pulled tightly onto the rim of receptacle 80 (see Figure 8) maintaining receptacle 80 on base 90. Because three equally spaced pairs of apertures 96 have been employed for securing the three lines 30, lines 30 preclude receptacle 80 from falling from base 90 because of the disposition of the hooks 84 and supporting lines 30 at 120 degrees 12Z9~84 1 to one another.
With reference to Figures 9 and 10, each connector 100 comprises an injection molded part comprised of polycarbonate and carries slot 102 having width "w", height "h" and varying depth "d" opening through both upper end 104 and lower end 106. At each side edge of slot 102, air-cuter slot portions 108 and 110 are of greater depth "d" than inter-mediate slot portion 112 between portions 108 and 110, the depth "d" of slot portion 112 being less than the thickness of line 30, however the depth "d" of portions 108 and 110 being greater than line 30. Slot portion 110 has a wider slot portion or socket Lola extending from intermediate upper and lower ends 104 and 106, to end 106 where it opens. The end of line 30 carries bell-shaped metal member 114 carrying radially directed flange 116 at one end arid is secured through hole 120 in member 114 by the end of line 30 being knotted at 122 (see Figure 10). Member 114 is wider than slot 110 but narrower than slot portion Lola and is about the length of slot portion AYE to seat in socket AYE
and lock line 30 to connector 100.
With reference to Figure 12, another method of securing planter 80 to base 88' similarly constructed to base 88 is shown which employs only two hooks and two long lines secured to one hanger support (not shown). Particularly, base 88' carries two sets of well spaced aver-lures AYE and 124B on skirt 94' and a third aperture 126 intermediate apertures AYE and 124B. The reason for such spacing is to ensure the end portions of line 30 extending upwardly from base 88', portion AYE
and 30B, are spaced enough to hold the receptacle, along with hooks 84' secured to the rim of the receptacle (planter - not shown, from falling from base 88'. On the under surface of skirt 94' are curved spacer surfaces (not shown) between apertures 124B and 126, and AYE and 126, against which line 30 abuts, also to prevent extreme bends in the line to prevent weakening of the line. Therefore, as is apparent, a loop 86' ~229~34 1 Of material 30C carrying a hook extends through each aperture 126 with the continuation of the two ends of loop 86' extending through aperture 126 behind skirt 94' to abut the curved surfaces (not shown), with the end of loop 86' emanating from that portion between hook 84' and aperture 126 extending towards the aperture AYE or 124B remote the portion between hook 84' and aperture 126 from which it emanates. Therefore, portion 30C' closest aperture AYE (remote aperture 124B) 'crosses over' portion 30C" and extends to aperture 124B and portion 30C" closest aperture 124B (remote aperture AYE) 'crosses-over' portion 30C' and extends to aperture AYE, each abutting the curved surface (not shown) and, passing from behind skirt 94' through the respective aperture vertically to the support.
Therefore, any planter carried on base 88' is fully supported so that it cannot fall out when hooks 84' are applied to the planter's rim and prevented from falling by the loops of material 30C and hooks 84' and the widely spaced vertically extending portions AYE and 30B.
As many changes can be made to the embodiments without de-parting from the scope of the invention, it is intended that all matter contained herein be interpreted as illustrative of the invention and not in a limiting sense.
