Description
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates in general to devices which hold bags for
collecting materials and more particularly to a travelling bag
holder.
Commercially available plastic and paper garbage disposal bags have
been found to be economically advantageous and convenient for
collecting and disposing of various types of waste materials.
However, in using such bags, there is a need for some means of
holding the bag in an opened configuration as it is moved around to
collect refuse. Portability and support of the bag itself is also
needed to reduce the amount of effort required per bag-full of
refuse collected. Prior art travelling dustbins are generally
clumsy and heavy even though they can be used to hold disposal
bags.
The invention provides a travelling bag holder of relatively light
weight frame construction which can hold and carry in opened
configuration plastic and paper bags such as are commonly sold for
garbage disposal.
According to the invention, the bag holder has a base that can be
interchangeably equipped with a set of caster wheels or a pair of
ski runners for travel thereupon. A pair of arms releaseably
connected to the base extend upward therefrom and engage the bag to
support and carry it in an opened configuration. These arms extend
from opposite sides of the base and are resiliently displaceable
toward each other to receive a bag having an opening dimension less
than the free span between the ends of the arms. Thus, the arms are
biased to hold the bag open.
For a better understanding of the invention and its several
advantages, reference should be had to the accompanying drawing and
following detailed description pertaining to certain preferred
embodiments of the invention.

DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
In FIGS. 1-3 there is exemplified a bag holder 10 having a base 11
equipped with caster wheels 12 for movement over a supporting
surface, such as a floor or the ground (not shown).
Connected to base 11 at opposite sides thereof are a pair of arms
13 that extend upwardly from base 11 and supportingly engage a bag
14, the skirt portion 15 of bag 14 being turned down and over the
end of each arm 13. The arms 13 are generally similar and of metal
rod construction, as better seen from the upside-down exploded
holder 10 shown in FIG. 2. Each arm 13 can be considered as
somewhat U-shaped having a transverse end section 16 connected to
opposing upright sections 17 to which is welded a brace 18.
Releaseable connection of each arm 13 to base 11 is achieved by
shank portions 19 extending in a common plane and which are
received in corresponding clamps 20 provided on the underside of
base 11. The shanks 19 of each arm 13 are inclined at a divergent
angle in relation to each other, and the pair of clamps 20 which
receives these shanks 19 have strap seats 21 that are similarly
inclined.
To connect each arm 13 to base 11, wing nuts 22 on bolts 24 are
loosened such that both strap seat pieces 21 can be easily sprung
away from top piece 23 to allow insertion of both shanks 19 into
the matching cavities of respective strap seats 21, and then wing
nuts 22 are tightened to effect clamping of each shank 19 between
top piece 23 and the associated strap seat 21. FIG. 6 shows in
detail the structure of a typical clamp 20 and how its wing nut 22,
bolt 24 and strap seat 21 piece cooperate with top piece 23.
For a more secure gripping of the arms 13, each strap seat 21 is
provided with a dimple or detent 25 that is received in a
corresponding notch 26 of the shank 19.
The divergent angle arrangement of the shanks 19 makes it more
difficult to accidentally pull them out of clamps 20 in the event
nuts 22 should loosen, but yet because of the flexibility of the
resilient rod structure of the arms 13, the shanks 19 can be easily
inserted into clamp 20.
This resilience of arms 13 is utilized for holding bag 14 in an
opened configuration. The arms 13 when connected to base 11 are
outstretched therefrom such that the free span, i.e., without the
bag 14 in place, between the end sections 16 of opposing arms 13 is
larger than the opening dimension of bag 14 when held by arms 13 as
shown in FIG. 1, and as measured between the end sections 16 with
the bag 14 in place. Thus, the arms 13 are resiliently displaceable
toward each other to receive a bag 14 having an opening dimension
less than the free span between the ends 16 of arms 13.
Although in many cases the contact friction between the turned over
portion 15 of bag 14 and the arms 13 will be sufficient to keep the
bag 14 from slipping as it becomes filled, as with refuse, the
invention provides an elongated ring type clamp 28, somewhat
similar in shape to brace 18, which slidably fits over selected arm
13 and the bag portion 15 that is turned over the end 16 of that
arm 13, and operates to secure bag portion 15 to arm 13 as better
seen in FIG. 3.
A removable, hinge type cover 29 can be used in connection with
holder 10 for closing the opening presented by bag 14. Cover 29 has
a pair of spaced hooks 30 shaped to hang and swing around the end
section 16 of one arm 13 with bag 14 in place as shown in FIGS. 1
and 3. When swung into the closed position, the end of cover 29
opposite hooks 30 rests upon the bag covered end section 16 of the
other arm 13.
The arms 13 grip the bag 14 in a manner somewhat analogous to the
way a bowstring is held, in that the upright sections 17 are bent
at 31 so that end sections 16 tend to hook into the pocket 33
formed by turning down section 15 of the bag 14.
The bag holder 10 can be adapted to hold various depth sizes of
bags similar to bag 14 by substituting for each of the arms 13 an
arm assembly 35 as shown in FIG. 7. Arm assembly 35 has upright
sections 36 similar to those of arm 13, except that instead of
being integrally connected to a transverse end section, the
sections 36 are adjustably connected to a separate end section 37.
Expediently, upright sections 36 are made of rod or tubing smaller
in diameter than the inside diameter of tubing used to make end
section 37. Section 37 is thus drilled and tapped to receive set
screws 38 that are turned to lock section 37 to the end of sections
36 received inside section 37. The effective length of arm assembly
35 can be therefore adjustably set as required for the bag
used.
FIGS. 4, 5 and 6 illustrate how the same basic bag holder 10 can be
equipped with runners 41 instead of casters 12. From FIGS. 2 and 6
it can be noted that the base 11 is provided with means for
receiving conventional caster wheels 12 at each of four corner
bosses 42. Each corner boss 42 has installed in it a fitting 43 for
receiving a standard caster shank 44, such as commonly come as
parts of commercially available caster wheels 12. Accordingly, to
fit base 11 with runners 41 it is merely necessary to remove
whatever wheels 12 are installed and insert into the fittings 43
the similar shanks 45 and 46 used to secure each runner 41 to a
corresponding in-line pair of bosses 42.
To avoid fitting problems as might occur if both shanks 45 and 46
were fixedly connected to the runner 41, only the one shank 45 is
fixedly connected to runner 41, and the other shank 46 extends
through an elongated hole 47 in runner 41 and is provided with a
rectangular flange 48 that seats flush into a recess 49 provided in
the bottom of runner 41, as shown in phantom by FIG. 5. The recess
49 and elongated hole 47 allow a certain degree of movement for
shank 46 so that its distance to shank 45 can be adjusted to
compensate for variations in the actual layout distance between the
fittings that receive the shanks 45, 46.
From the foregoing, it can be appreciated that the invention is
adaptable in numerous ways to meet the requirements of a specific
bag holding application, and provides a basic structure that can
travel on wheels 12 or interchangeable runners 41.
While a specific embodiment of the invention has been shown and
described in detail to illustrate the application of the principles
of the invention, it will be readily understood and appreciated
that various changes or modifications thereof may be made without
departing from the spirit or scope of the invention.
