Description
TRANSPORTABLE AND COLLAPSABLE
BAG CA~RYING CART
Backqround of the Invention-.
This invention relates to a transportable bag 5 holding device for use in collecting and conveying materials such as bedding, laundry or trash in hotels, hospitals or the like. More particularly, this invention relates to a new and improved bag carrying cart which is similar to the cart disclosed in my earlier U.S. Patent No. 4,549,748, but which includes several improved features including, for e~ample, improved folding ability and foot actuated lifting means associated with the cart's cover.
My earlier U.S. Patent No. 4,549,748, which is incorporated herein in its entirety, related to a novel bag holding device for use in collecting and conveying materials such as bedding, laundry or trash in a hospital, hotel or other institution. The bag holding cart of Patent No. 4,549,748 is comprised, in part, of a pair of inverted U-shaped frame support members pivotally connected at about their respective centers. A foldable base is provided to the lower portion of the cart, the base preferably having a locking means attached thereto. The cart is movable along conventional wheels or casters for easy transport. The upper portion of each inverted~
U-shaped support member is provided with novel bag retention safety bars which help to preclude bags, especially plastic bags, from sliding off the frame after material has been deposited therein. Finally, a hand actuated cover or lid assembly effects adequate closure while permitting ease of opening.
While well suited for its intended purposes, the bag holding cart of Patent No. 4,549,748 suffers from several perceived deficienciles and disadvantages.
For example, while the cart is foldable (see FIGURE 4 of Patent 4,549,748) for ease of storage and shipping, even in its folded state, the cart is rather bulky and cumbersome. Also, the slidable cover of my earlier cart must be opened and closed by hand. Unfortunately, such hand operation can be problematic, especially if the cart operator is loaded down with laundry, rubbish, etc. In that case, the operator must first put the load down, then open the cover, and finally pick up the load again and deposit it into a bag supported on the cart.
Accordingly, the hand actuated cover leads to labor inefficiency during cart use.
Summary of the Invention:
The above-discussed and other problems and deficiencies of the prior art are overcome or alleviated by the improved device for use in collecting and conveying materials in a hospital, hotel, or other institution of the present invention. In accordance with the present invention, - ~g~
a bag holding cart of the type disclosed in U.S.
Patent No. 4,549,748 includes a pair of inverted U-shaped frame support members pivotably connected at about their respective centers. A unitary base is provided to the lower portion of the cart. This base is pivotably connected to one of the frame members and is detachably connected to the other frame member preferably via a spring clip mechanism which affords a snap lock between the frame member and the base.
This unitary base and associated snap lock mechanism is an important feature of the present invention as it permits the cart to be folded in a very compact fashion for improved storage and transport.
Another important feature of the present invention is a foot pedal actuated cover or lid.
This cover is pivotably attached to the upper portion of the cart and may be actuated by a foot pedal which is linked to the cover by a pair of wire supports.
The foot actuated cover permits the lid to be opened without the use of the operator's hands. This is especially advantageous in those situations wherein the operator's arms are loaded down. In that case, the operator simply opens the lid by foot pressure and conveniently deposits the material into the bag supported on the cart.
Much of the remaining structural features of the present invention are substantially similar to those features described in the aformention U.S. Patent 4,549,748.

The above-described and other features and advantages of the present invention will be appreciated and understood by those skilled in the art from the following detailed description and drawing.
Brief Description of the Drawings:
Referring now to the drawings, wherein like elements are numbered alike in the several FIGURES:
FIGURE l is a perspective view of a cart in accordance with the present invention without a bag being inserted therein;
FIGURE 2 is a side elevation view of the cart of FIGURE l;
FIGURE 3 is a side elevation view, similar to FIGURE 2, during the folding operation;
FIGURE ~ is a side elevation view of the cart of FIGURE l subsequent to being folded;
FIGURE 5 is an enlarged side elevation view of the lower portion of the cart of FIGURE l;
FIGURE 6 is an enlarged sectional view of a first portion of FIGURE 5; and FIGURE 7 is an enlarged sectional view of a second portion of FIGURE 5; and FIGURE 8 is an enlarged view along the line 8-8 of FIGURE l.
Description of the Preferred Embodiment:
Referring first to FIGURES l and 2, a bag holding transportable cart in accordance with the present ' 9~
invention is shown generally at 10. Cart 10 is comprised of a pair of inverted U-shaped frame support members 12 and 14 pivotally connected about two corresponding bearlngs 16 and 18. This pivotal connection is preferably along the center of each vertical leg of U-shaped members 12 and 14. As will be discussed in greater detail hereinafter, cart 10 also includes a pivotable cover assembly 20 which is capable of opening and closing under the action of a foot pedal 22; and a base or rack 24 which interconnects the lower portion of frame members 12 and 14. Each U-shaped member 12 and 14 has a vertical straight section 23 which supports a conventional castor or roller 25.
Base or rack 24 is preferably unitary or one piece and provides support for the bags (not shown) after material (i.e., laundry, rubbish, etc.) has been added therein. Base 24 is preferably comprised of a plurality of perpendicular rods including longitudinal rods 26 and latitudinal rods 28. Base 24 is pivotably connected to the front of frame members 12 and 19 in a manner which allows it to be pivoted and fol~ed upwardly or downwardly. One preferred manner of achieving this pivotal connection is shown in FIGURES 5 and 6. Referring to FIGURES 5 and 6, in one embodiment, base 24 (actually longitudinal rod 26a) is pivotably attached to a cross-bar 30 interconnecting frame supports 12 and 14 via a small U-bend 32 to form a swingable hinge assembly. Cross-bar 30 may be welded or otherwise ~L3~
secured between members 12 and 14; while U-bend 32 will be welded or otherwise secured to cross-bar 30.
It will be appreciated that longitudinal rod 26a of base 24 will swing or pivot within U-bend 32.
The opposite end of base 24 is detachably connected to the opposing ends of support members 12 and 14. Referring to FIGURES 5 and 7, an L-bend or similar retaining means 34 is provided on straight portions 23 Eor receiving longitudinal rod 26b of unitary base 24. Rod 26b is retained within L-bend 34 by any suitable means such as snap-lock action performed by spring-clips 36. Spring clips 36 are preferably made from a suitable spring steel and can be pushed inwardly away from rod 26b to permit removal of rod 26b from within L-bend 34. Spring clips 36 may be attached to straight portions 23 by any suitable means such as, for example, fastening means 39. A second cross bar 37 is also provided between members 12 and 14 to rigidize and support the assembled frame.
Turning now to FIGURES 1, 2, 5 and 8, a discussion of the foot operated cover assembly follows. The cover assembly i~cludes lid 20 having depending side portions 40, a rigid shaft 42 attached between side portions 40, a pair of clips 44 which slip onto shaft 42, wire support rods 46 attached to clips 44 and foot pedal 22 pivotably connected to rods 46 Shaft 42 is welded or otherwise permanently attached to the cross-piece of U-frame 14. Each Clip ~L3gN~
~ preferably have a flat base 48 with a pair of parallel sides 50 extending transverse to base 48.
Aligned openings 52 are provided in each extending side 50 with shaft 42 being received in openings 52.
Openings 50 are sized to permit shaft 42 to freely pivot therewithin. Clip 44 is attached to the back depending surface 54 of lid 20. Lid 20 also includes oppositely disposed protrusions 56 which receive either end of shaft 42 and act to both align and retain shaft 42 in position. Protrusion 56 also act as a bearing surface between lid 20 and shaft 42.
Foot pedal 22 has a pair of lateral L-shaped extensions 58 which pivotably attach to base 24 at bearing mount 60. Bearing mount 60 is preferably welded onto latitudinal rods 28 and comprise a cylindrical housing which receives the ends of L-shaped extensions 58 therein. The ends of support rods 46 are looped and are connected to corresponding looped ends of a transve~se rod 62 ~see FIGURE 1) which interconnects both support rods 46 and is welded or otherwise secured to L-shaped e~tensions 58. Thus, when foot pedal 22 is forced downwardly, extensions 58 will also pivot downwardly (via bearing mount 60) bearing against transverse rod 62. As transverse rod 62 is urged downwardly by e~tensions 58, support rods 46 will be pulled in the direction illustrated by the arrows in FIGURE 2 urging clips 44 in the same direction and causing lid 20 to pivot ~L3~
about shaft 42 so as to and be urged open as shown in FIGURES 1 and 2. Upon release of the foot pedal, the reverse takes place with the lid pivoting closed.
As mentioned, an important feature of the present invention is its ability to close into a compact form. Referring first to FIGURE 3, during the closure or folding operation, base 24 is initially disengaged from both L-bends 34 by urging the spring clips 36 toward supports 12 and 14 and lifting base 24 upwardly. At this point, base 24 will swing about the hin~e described in conjunction with FIGURE 6 and cart 10 will fold into the compact shape shown in FIGURE 4 with frame support members 12 and 14 pivoting about bearings 16 and 18 and the cover dropping forward and down as it pivots about pivoting shaft 42. The significance of the looped ends of support rods 46 is apparent in FIGURE 4. Thus, during closure, rods 46 will be urged forward with the elongated looped ends providing the necessary "float" to preclude rods 46 from bending (compare FIGURES 3 and 4).
It will be appreciated that the important bag holding features of cart 10 are identical to the bag holding features described in U. S. Patent 4,5g9,748. Thus, referring now to FI5URES 1-3 of my prior Patent ~o. 4,549,748, each of the two cross-piece segments of U-shaped members 12 and 14 are provided with a pair of bag retention safety bars identified at 38 and 40. These bars 38, 40 are ~L3~19~
preferably welded onto U-shaped frames 12 and 14, respectively. Safety bars 38 and 40 are preferably comprised of two parallel straight portions 42 and 44 interconnected at each end by a U-shaped retaining member 46. As shown in FIGURE 3 of the 4,549,748 Patent, when either a plastic or cloth bag 48 is mounted on the cart 10, the bag should be mounted so as to overlap and fit tightly about the two safety bars 38 and 40. If a heavy load is added to the bag 48 and the bag is plastic, the bag will be urged downwardly (and the overlap urged upwardly). In accordance with the present invention, if the bag slides as suggested, the outer edges thereof will slip into the notches provided by the two safety bars 38 and 40 and be securely loaded therein. As a con-sequence thereof, plastic bags 48 will be prevented from premdturely slipping out of the cart 10. It will be appreciated that the bags should not be lifted upwardly out of the cart during changing, but instead should be removed from the front of the cart frame. Also, in a preferred embodiment, strips 60, 62 of the Velcro -type self-adhesive material are applied to at least one of the cross-piece segments of U-shape members 12 and 14. Similarly, correspond-ing strips of Velcro-type fasteners are attached onto fabric (i.e., cloth, canvas, etc.) bags. Thus, when the fabric bags are mounted onto the cart as shown in FIGURE 3, the Velcro-type fasteners will securely fix the heavier (relative to light weight plastic) fabric bags to the cart frame.
Similarly, cart 10 of the present invention may also be used with the various basket assemblies and interlocking correcting devices described in FIGURES 5-8 of U.S. Patent No. 4,599,478.
The novel bag holding cart of the present invention thus maintains many important features of the earlier cart of Patent No. 4,599,748, while improving on its disadvantages. The use of a unitary base which detachably connects to the frame permits 10 folding of the unit into a self-contained space saving flat position (FIGURE 4) for improved storage and lower shipping costs. The foot operated cover assembly precludes the use of hands, thereby permitting operation of the cart when both arms of 15 the operator are loaded with material to be added into the bag.
While preferred embodiments have been shown and described, various modifications and sub-stitutions may be made thereto without departing from 20 the spirit and scope of the invention. Accordingly, it is to be understood that the present invention has been described by way of illustrations and not limitation.

Description of the Preferred Embodiment:
Referring first to FIGURES l and 2, a bag holding transportable cart in accordance with the present ' 9~
invention is shown generally at 10. Cart 10 is comprised of a pair of inverted U-shaped frame support members 12 and 14 pivotally connected about two corresponding bearlngs 16 and 18. This pivotal connection is preferably along the center of each vertical leg of U-shaped members 12 and 14. As will be discussed in greater detail hereinafter, cart 10 also includes a pivotable cover assembly 20 which is capable of opening and closing under the action of a foot pedal 22; and a base or rack 24 which interconnects the lower portion of frame members 12 and 14. Each U-shaped member 12 and 14 has a vertical straight section 23 which supports a conventional castor or roller 25.
Base or rack 24 is preferably unitary or one piece and provides support for the bags (not shown) after material (i.e., laundry, rubbish, etc.) has been added therein. Base 24 is preferably comprised of a plurality of perpendicular rods including longitudinal rods 26 and latitudinal rods 28. Base 24 is pivotably connected to the front of frame members 12 and 19 in a manner which allows it to be pivoted and fol~ed upwardly or downwardly. One preferred manner of achieving this pivotal connection is shown in FIGURES 5 and 6. Referring to FIGURES 5 and 6, in one embodiment, base 24 (actually longitudinal rod 26a) is pivotably attached to a cross-bar 30 interconnecting frame supports 12 and 14 via a small U-bend 32 to form a swingable hinge assembly. Cross-bar 30 may be welded or otherwise ~L3~
secured between members 12 and 14; while U-bend 32 will be welded or otherwise secured to cross-bar 30.
It will be appreciated that longitudinal rod 26a of base 24 will swing or pivot within U-bend 32.
The opposite end of base 24 is detachably connected to the opposing ends of support members 12 and 14. Referring to FIGURES 5 and 7, an L-bend or similar retaining means 34 is provided on straight portions 23 Eor receiving longitudinal rod 26b of unitary base 24. Rod 26b is retained within L-bend 34 by any suitable means such as snap-lock action performed by spring-clips 36. Spring clips 36 are preferably made from a suitable spring steel and can be pushed inwardly away from rod 26b to permit removal of rod 26b from within L-bend 34. Spring clips 36 may be attached to straight portions 23 by any suitable means such as, for example, fastening means 39. A second cross bar 37 is also provided between members 12 and 14 to rigidize and support the assembled frame.
Turning now to FIGURES 1, 2, 5 and 8, a discussion of the foot operated cover assembly follows. The cover assembly i~cludes lid 20 having depending side portions 40, a rigid shaft 42 attached between side portions 40, a pair of clips 44 which slip onto shaft 42, wire support rods 46 attached to clips 44 and foot pedal 22 pivotably connected to rods 46 Shaft 42 is welded or otherwise permanently attached to the cross-piece of U-frame 14. Each Clip ~L3gN~
~ preferably have a flat base 48 with a pair of parallel sides 50 extending transverse to base 48.
Aligned openings 52 are provided in each extending side 50 with shaft 42 being received in openings 52.
Openings 50 are sized to permit shaft 42 to freely pivot therewithin. Clip 44 is attached to the back depending surface 54 of lid 20. Lid 20 also includes oppositely disposed protrusions 56 which receive either end of shaft 42 and act to both align and retain shaft 42 in position. Protrusion 56 also act as a bearing surface between lid 20 and shaft 42.
Foot pedal 22 has a pair of lateral L-shaped extensions 58 which pivotably attach to base 24 at bearing mount 60. Bearing mount 60 is preferably welded onto latitudinal rods 28 and comprise a cylindrical housing which receives the ends of L-shaped extensions 58 therein. The ends of support rods 46 are looped and are connected to corresponding looped ends of a transve~se rod 62 ~see FIGURE 1) which interconnects both support rods 46 and is welded or otherwise secured to L-shaped e~tensions 58. Thus, when foot pedal 22 is forced downwardly, extensions 58 will also pivot downwardly (via bearing mount 60) bearing against transverse rod 62. As transverse rod 62 is urged downwardly by e~tensions 58, support rods 46 will be pulled in the direction illustrated by the arrows in FIGURE 2 urging clips 44 in the same direction and causing lid 20 to pivot ~L3~
about shaft 42 so as to and be urged open as shown in FIGURES 1 and 2. Upon release of the foot pedal, the reverse takes place with the lid pivoting closed.
As mentioned, an important feature of the present invention is its ability to close into a compact form. Referring first to FIGURE 3, during the closure or folding operation, base 24 is initially disengaged from both L-bends 34 by urging the spring clips 36 toward supports 12 and 14 and lifting base 24 upwardly. At this point, base 24 will swing about the hin~e described in conjunction with FIGURE 6 and cart 10 will fold into the compact shape shown in FIGURE 4 with frame support members 12 and 14 pivoting about bearings 16 and 18 and the cover dropping forward and down as it pivots about pivoting shaft 42. The significance of the looped ends of support rods 46 is apparent in FIGURE 4. Thus, during closure, rods 46 will be urged forward with the elongated looped ends providing the necessary "float" to preclude rods 46 from bending (compare FIGURES 3 and 4).
It will be appreciated that the important bag holding features of cart 10 are identical to the bag holding features described in U. S. Patent 4,5g9,748. Thus, referring now to FI5URES 1-3 of my prior Patent ~o. 4,549,748, each of the two cross-piece segments of U-shaped members 12 and 14 are provided with a pair of bag retention safety bars identified at 38 and 40. These bars 38, 40 are ~L3~19~
preferably welded onto U-shaped frames 12 and 14, respectively. Safety bars 38 and 40 are preferably comprised of two parallel straight portions 42 and 44 interconnected at each end by a U-shaped retaining member 46. As shown in FIGURE 3 of the 4,549,748 Patent, when either a plastic or cloth bag 48 is mounted on the cart 10, the bag should be mounted so as to overlap and fit tightly about the two safety bars 38 and 40. If a heavy load is added to the bag 48 and the bag is plastic, the bag will be urged downwardly (and the overlap urged upwardly). In accordance with the present invention, if the bag slides as suggested, the outer edges thereof will slip into the notches provided by the two safety bars 38 and 40 and be securely loaded therein. As a con-sequence thereof, plastic bags 48 will be prevented from premdturely slipping out of the cart 10. It will be appreciated that the bags should not be lifted upwardly out of the cart during changing, but instead should be removed from the front of the cart frame. Also, in a preferred embodiment, strips 60, 62 of the Velcro -type self-adhesive material are applied to at least one of the cross-piece segments of U-shape members 12 and 14. Similarly, correspond-ing strips of Velcro-type fasteners are attached onto fabric (i.e., cloth, canvas, etc.) bags. Thus, when the fabric bags are mounted onto the cart as shown in FIGURE 3, the Velcro-type fasteners will securely fix the heavier (relative to light weight plastic) fabric bags to the cart frame.
Similarly, cart 10 of the present invention may also be used with the various basket assemblies and interlocking correcting devices described in FIGURES 5-8 of U.S. Patent No. 4,599,478.
The novel bag holding cart of the present invention thus maintains many important features of the earlier cart of Patent No. 4,599,748, while improving on its disadvantages. The use of a unitary base which detachably connects to the frame permits 10 folding of the unit into a self-contained space saving flat position (FIGURE 4) for improved storage and lower shipping costs. The foot operated cover assembly precludes the use of hands, thereby permitting operation of the cart when both arms of 15 the operator are loaded with material to be added into the bag.
While preferred embodiments have been shown and described, various modifications and sub-stitutions may be made thereto without departing from 20 the spirit and scope of the invention. Accordingly, it is to be understood that the present invention has been described by way of illustrations and not limitation.
