ABSTRACT:
BACKGROUND OF THE INVENTION
My invention relates in general to a means for holding a fillable bag upright while it is filled with garden refuse, construction debris, kitchen debris or useable materials with a need for transport. Other materials are also appropriate without limitation, if the bag or container is not chemically damaged by such contents. In particular my invention relates to an mechanical apparatus which maintains a bag or container in an open and upright position while it is filled manually from the bottom upwardly.
My apparatus, hereinafter referred to as an improved modified universal adjustable bag holder, can be inserted into the ground to support and hold a bag open in the preferred embodiment. However, other embodiments which need not be inserted into the ground are also within the scope of my invention. Another embodiment of my invention comprises a vertical support which can support a bag or container in an upright position on both the front and back sides of the vertical support.
My bag holder in the preferred embodiment has ground-engagable feet and adjustable angled arms over which the bag or container is positioned and fastened. The angled arms are moved vertically by an adjustment by which the angled arms are physically connected.
In the preferred embodiment polyvinyl chloride piping(PCV), most preferably hollow and with an inner diameter of approximately 2 and ½ inches throughout, is the construction material of choice for the bag raising mechanism. However, embodiments composed of other materials such as steel tubing or hollow wooden segments are acceptable if they possess requisite strength, rigidity, and/or resilience. Combinations of these materials are acceptable as well in other embodiments.
In the preferred embodiment the two angled arms are generally open and parallel to the ground. The arms form a circumference of approximately 36 inches. The arms have a diameter of approximately 26.0 inches when the arms are in their most open position. However my invention is not limited to this particular diameter or circumference. The diameter and circumference may be varied depending upon the particular use and the diameter of the bags or containers. Also, the diameter can be changed by manually adjusting the angles of the two arms.
When the two angled arms are parallel to the ground, there is an gap remaining in the most anterior portion of the circumference, and with no pipe or other support whatsoever. This opening facilitates the removal and attachment of a bag to the angled horizonal arms, as well as widthwide bag expansion.
In the preferred embodiment there are also attachments on both angled arms. Preferably these attachments ares detachable VELCRO® hook and loop fastener tabs which prevent the bag from slipping or collapsing during use.
Other devices are ubiquitous in the prior art. In U.S. Pat. No. 4,358,083 (Haubrich), a device was described with a fully circumscribed hoop, removable bag attachments, and ground engaging feet. T-shaped members were movably mounted on a cross bar for adjusting the size of the metal hoop.
SUMMARY OF THE INVENTION
In the preferred embodiment, my universal bag holder is adapted for use in construction areas for containing debris (ie., a contractor's bag). The more the user pulls on the bag the tighter the bag fits into the apparatus. A square bag holder is also within my invention with VELCRO® hook and loop fastner tabs instead of tiebacks. For use in construction, a plastic bag is preferable because it can stretch with increasing contents. For example, a 39 (thirty-nine) gallon leaf and grass plastic bag is ideal.
Canvas is also acceptable as well as paper for bag or container construction. Nevertheless, the property of stretch and elasticity is lost when using these materials. The advantage with paper of course, is that it is generally biodegradable, whereas most plastic bags, with notable exceptions are not. The bag or container is attached anteriorly upon the angled arms to a curved vertical support. To construct my preferred bag holder, the materials cost approximately $6.00 per device, excluding labor and collateral costs.
As such, one goal of my invention is to provide an improved bag holding device for construction sites and other uses.
Another goal of my invention is to provide a bag holding device with arms which provide an anterior access to an upright bag or container.
Another goal of my invention is to provide a device which can hold a bag on angled arms on both sides of a vertical curved support structure.
Still another goal of my invention is to provide a bag holding device which can simultaneously allow a plastic bag to stretch horizontally and be raised to its full height vertically.
Still another goal of my invention is to provide a device to hold a suitable bag or container to fill with household goods or other storable items.
