Description
FIELD OF THE INVENTION
Suspendible device for holding items, particularly for suspension on a ladder.
BACKGROUND OF THE INVENTION
Suspendible containers are often helpful to users of ladders, scaffolding, ledges and the like. These users often require the containers to hold their tools and other work items. Examples of such tools and items include paintbrushes, cans of paint, and tools used by window washers and builders. The number of possible uses for ladders and elevating apparatus, and the tools required for such uses, is unlimited. The prior art teaches a number of suspendible containers that can be elevated from building surfaces such as ladders, scaffolding and ledges. However, the prior art primarily is limited to containers that clamp to the edges of the top caps or rungs of a ladder or other elevating building surfaces. One such device is described in U.S. Pat. No. 4,480,810 (the “'810 patent”) entitled “Tool and Parts Tray.” The '810 patent discloses a suspendible ladder pan that is attachable to the top cap or rungs of a ladder through the use of an adjustable clamping member.
Many ladders today are manufactured with holes in their top caps. However, none of the prior art teaches a removable suspendible device that can be suspended exclusively from these holes on the top caps of ladders.
SUMMARY OF INVENTION
The present invention relates to a suspendible container for holding items, such as tools and paint cans, that is capable of being attached to a horizontal surface containing holes. At least one prong is attached to a container at one end, and at the other end is removably insertable into the hole on the horizontal surface. Preferably, the container has two prongs, which are adjustable along three dimensions, thereby enabling the container to be attached to a horizontal surface having holes of numerous configurations.
The present invention is particularly adaptable to be suspended from the top cap of a ladder. Top caps of ladders, typically are constructed with holes of various configurations. The adjustable nature of the prongs of the invention enable the container to be suspended from a variety of ladders containing a variety of configurations of holes. In addition, the adjustability of the prongs enables the bottom surface of the container to lay flat even as the ladder is positioned at various levels of inclination. In a preferred embodiment, the dimensions of the container are sufficient for holding tools, paint cans, and other items often needed by the users of ladders. The suspension of the container from the top cap of a ladder enables the user to have access to items inside the container while standing on the ladder.
Because the prongs of the device are removably insertable into a number of ladders, the device is both easy to use, efficient, and economical. The device, however, is not limited to use only with ladders, it may be used on scaffolding or other ledges that contain horizontal surfaces containing holes. In addition, the container could include a removable and/or rotatable lid for protecting items in the container.
In the preferred embodiment, the adjustable prongs are comprised of a horizontal member that is perpendicularly attached to a vertical member. The horizontal member is attached to a flange which is perpendicularly attached to the top edge of one of the sidewalls of the container. The horizontal member is adjustably attached to the flange and the vertical is adjustably attached to the horizontal member.

24
. In this preferred embodiment, the vertical member
26
is shown in the form of a stove bolt
32
. Each horizontal member
24
contains a channel
50
through which the stove bolt
32
may be inserted. The stove bolt
32
contains a head
54
which is wider than the channel
50
. Accordingly, as the stove bolt
32
is inserted through the channel
50
, the head
54
cannot pass through the channel
50
. A hex-nut
34
is then threadable onto the bottom of the stove bolt
32
to rest against the underside of the horizontal member
24
, thereby holding the stove bolt
32
in place along the channel
50
. As illustrated in
FIGS. 6-8
, the stove bolt
32
can be attached to the horizontal member
24
at any point along the channel

can be suspended from any member of configurations of holes
14
in a horizontal surface
12
.
As discussed above, the flange
52
and the container
16
can be one piece made of the same material. For example, the flange
52
and container
16
can be molded together or can be made from one piece of sheet metal. In another embodiment, the flange
52
and container
16
are separate pieces that are attached to each other.
FIG. 9
illustrates a preferred embodiment of the flange
52
where the flange
52
is comprised of a projecting arm
28
and an attachment arm
30
. Device

is shown in FIG.
10
. In this embodiment, the flange
52
is attached to the container
16
. Preferably, the attachment arm
30
of the flange
52
is attached to the container
16
by welding. However, the manner by which the flange
52
is attached to the container
16
is discretionary. As a result, the flange
52
could be attached to the container
16
by an adhesive, rivets, and the like. In this embodiment, the attachment arm
30
is generally perpendicularly oriented to the projecting arm
28
. Preferably, the projecting arm
28
has a length that is shorter than the attachment arm, and the projecting arm
28
is centrally located along the attachment arm
30
. The horizontal member
24
is attached to the projecting arm
28
, in the manners previously described in relation to
FIGS. 1-8
.
Reference is now made to
FIG. 11
which is another embodiment of the device
58
. In this embodiment, the horizontal member
24
is attached to the top edge of one of the sidewalls
18
directly. In this embodiment, the horizontal member may be adjustably attached to the sidewall
18
by any number of adjustable fasteners currently known in the art or later developed. Alternatively, the horizontal member
24
could be fixedly attached to sidewall
18
. This embodiment also shows an optional lid
42
which may be removably attached to one of the sidewalls
18
.
In an alternative embodiment, the container
16
could be made of two pieces so as to be adjustable in size. As illustrated in
FIGS. 12-14
, this is accomplished by allowing an inner piece
100
to fit inside an outer piece
102
. A folded or formed channel
104
is located on a top edge
106
of the outer piece
102
to hold a top edge
108
of the inner piece
100
allowing them to slide together. Holes
100
are formed through the top edges of both pieces to permit the pieces to be locked together, with a clip
112
, at the desired size. Instead of one flange
52
on the side of the container
16
, there are two shorter brackets
114
, one on the inner piece
100
and one on the outer piece
102
. Each bracket
114
would be designed to allow the same adjustability as the flange
52
. The clip
112
is made to insert through two of the holes
110
on the top edge. The clip
112
has a groove
116
cut in a pin part
118
to allow an “E” ring
120
to snap onto it, thus securing the pin
118
in place. The pins
118
could also be made with a knob
122
on the end causing it to snap in place. Each half of the container
16
would be similar in shape to the original design, but would be 10 ¼″ long, allowing adjust from approximate 14″ to 19″ in length.
Although this invention has been illustrated by reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made which clearly fall within the scope of the invention. The invention is intended to be protected broadly within the spirit and scope of the appended claims.
