Description
Background of the Invention
This invention relates to a collection bag carrier which is operative to maintain a flexible bag such as a refuse bag in an opened condition to facilitate filling the same.
In using a flexible bag, it is often difficult and frustrating for a user in trying to maintain the top of the bag in the opened condition while filling it. This is particularly troublesome in using a plastic bag such as a plastic refuse bag in a yard in which wind can cause the bag to collapse in a close condition rendering the filling operation arduous. Furthermore, the filling difficulty is complicated by the necessity of carrying the bag around the yard or work area to collect the refuse.
Heretofore, numerous support frames have been developed for maintaining the collection bag in an opened condition while it is being filled. However, such support frames are complex and bulky in construction and they are difficult to use or to store while they are not being used. Moreover, they are not convenient to be carried by the user moving around the working area.
Some support frames are provided with complex or numerous securing means of the bag such that it is burdensome in mounting the bag onto the frame or dismounting it therefrom.
Summary of the Invention
It is the principal object of the present invention to provide a carrier which is operative to maintain a flexible bag in an opening condition for filling operation.
It is another object of the present invention to provide a carrier which is simple in structure and it may be disassembled for storage or be assembled quickly for use.
It is another object of the present invention to provide a carrier which is adjustable to accommodate bags of various length.
It is yet another object of the present invention to provide a portable carrier which facilitates the user to move the bag conveniently around the work area for the filling operation.
It is still yet another object of the present invention to provide a carrier to which the mounting and dismounting of the bag may be carried out simply and expeditiously.

Detailed Description of the Preferred Embodiments
With reference to the drawings wherein like reference numerals designate corresponding parts in the several views, the carrier 10 according to the present invention has a base board 11 which is preferably generally square in shape. A first tubular post 12 is located preferably at the middle of the front edge portion of the base board 11 in a vertical manner. The tubular post 12 is removably mounted to a sleeve mounting 13 secured to the base board 11. The tubular post 12 is secured to the sleeve mounting 13 by a manually adjustable securing bolt 14 such that the tubular post 12 may be easily mounted to or dismounted from the sleeve mounting with ease. Similarly, a second tubular post 15 extending in a vertical manner is removably mounted to a sleeve mounting 16 located at the middle portion of the rear edge of the base board 11 and is located directly opposite to the first tubular post 12. The second tubular post 15 is also secured to the sleeve mounting 16 by a manually adjustable securing bolt 17 for the same purposes.
A first T-shaped mounting bracket 18 having a generally horizontal bar member 19 and an elongated vertical leg member 20 and it is mounted at the top of the first tubular post 12 with its vertical leg member 20 slidably inserted into the top of the first tubular post 12. The first T-shaped mounting bracket 18 may be fixed in place at a selected height by an adjustable set screw bolt 21 provided at the side of the top portion of the first tubular post 12, and a reinforcing sleeve 22 may be provided at the top end portion of the first tubular post 12. Vertical slots 23 and 24 are respectively formed at the two ends of the horizontal bar member 19 of the T-shaped mounting bracket 18.
A slider member 25 is slidably mounted on the vertical leg member 20 of the T-shaped mounting bracket 18. The mounting pressure of the slider member 25 to the leg member 20 may be adjusted by a set screw 26 provided at the side of the slider member 25 such that the slider member 25 will be maintained by the tightening pressure of the set screw 26 against the vertical leg member 20 to remain securely at a selected position. The slider member 25 may only be pushed with such force to another selected position without having to operate the set screw 26. Alternatively, a manually adjustable set screw bolt may be provided such that the bolt may be operated to enable the slider member 25 to be moved and secured at any selected position. A loop-shaped cable 27 is mounted to the slider member 18. The cable 27 has such a length that it may be looped over the horizontal bar member 19 of the T-shaped bracket 18 and to engage with the slots 23 and 24 of the latter. The engagement may be facilitated by sliding the slider member 25 upwards towards the horizontal bar member 19 such that the cable 27 is loosely engaging with the horizontal bar member 19. The engagement may then be tightened by sliding the slider member 25 downwards until the cable 27 is taut.
Similarly, a second T-shaped mounting bracket 28 is slidably mounted at the top of the tubular post 15. The T-shaped mounting bracket 28 has a horizontal bar member 29 and an elongated vertical leg member 30. The T-shaped mounting bracket 28 is secured to the tubular post 15 by a manually operative set screw bolt 31. The top end portion of the tubular post 15 is reinforced with a sleeve 32. The T-shaped mounting bracket 28 may be secured at any selected height by the set screw bolt 31. Vertical slots 33 and 34 are respectively formed at the two ends of the horizontal bar member 29 of the T-shaped mounting bracket 28. A slider member 35 is slidably mounted on the vertical leg member 30 of the T-shaped mounting bracket 28. The mounting pressure of the slider member 35 may be adjusted by the set screw 36 provided at the side of the slider member 35. A loop-shaped cable 37 is mounted to the slider member 35. The engagement of the loop-shaped cable 37 with the horizontal bar member 29 may be adjusted by sliding the slider member 35 similar to that of the engagement of the slider member 26 and horizontal bar member 19 as described above.
Two wheels 38 and 39 may be provided at the two sides of the base board 11 adjacent to the rear edge therein, and a tow rope 40 is mounted to the front edge of the base board 11 such that the carrier may be towed and be moved around a work area with ease. The tow rope 40 may be mounted to the sleeve mounting 13 or to the base board 11 directly. A hand grip 41 may be provided at the free end of the tow rope 40 to facilitate pulling the carrier 10 may be pulled by hand around the work area.
In use, the flexible bag 42 may be quickly mounted to the carrier 10 by folding a portion of opposite sides of its top rim over the horizontal bar members 19 and 29 of the T-shaped mounting brackets 18 and 28. The position of the T-shaped mounting brackets 18 and 28 may be adjusted by varying the length of the vertical leg members 20 and 30 inserting into the tubular posts 12 and 15 respectively so as to accommodate bags of different lengths. The slider members 25 and 35 are pushed upwards towards the horizontal bar members 19 and 29 such that the loop-shaped cables 27 and 37 may be easily looped over the folded top rim portion of the flexible bag 42 now wrapping over the horizontal bar member 19 and 29 and their end slots 23, 24 and 33, 34 of the T-shaped mounting brackets 19 and 29 respectively. After the engagement, the slider members 25 and 35 may then be pushed downwards away from the horizontal bar members 19 and 29 respectively until the cables 27 and 37 are tightly securing the portions of the top rim of the flexible bag 42 wrapping over the T-shaped mounting brackets 19 and 29 so as to secure the bag to the carrier as well as to maintain the top of the bag in the opened position for the filling operation. The carrier 10 with the bag 42 mounted thereon may be conveniently pull around the work area by hand with the tow rope 40. The filled bag may be quickly removed from the carrier 10 by pushing the slider members 25 and 35 upwards to loosen the engagement of the cables 27 and 37 with the T-shaped mounting brackets 18 and 28 respectively such that the cables 27 and 37 may be disengaged therefrom and the bag may then be removed from the carrier 10.
Although I have described certain features of the present invention in more or less detail, it will be apparent that various changes, additions, omissions and substitutions can be made therein without departing from the spirit of the invention or the scope of the appended claims.
