Abstract
Abstract A bag handling system used to facilitate the filling of bag by holding the bag open. The bag handling system is comprised of an inner locking frame through which the open end of a bag is passed such that it can be folded over the inner frame. The inner frame is then inserted in and secured into the channel of an outer base frame. The outer base frame includes an integrated hand grip and rails for the attachment of an extension handle/support leg. The outer base frame also has guide grooves for the attachment of a sweep pan to channelize the fill into a bag.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A bag handling system comprising: an inner frame defining a central opening therethrough; an outer frame of channel-shaped cross-section and having a shape corresponding to the shape of said inner frame so that said inner frame can fit within the channel of said outer frame; a hand grip rigidly joined to said outer frame; releasable locking tabs provided on said outer frame for holding said inner frame within the channel of said outer frame, said locking tabs extending partially into the channel of said outer frame; and rails rigidly joined to and extending along said outer frame on both sides of said hand grip, said rails serving as a means of releasably attaching an extension handle to said outer frame on either side of said hand grip to facilitate manipulation of an assembly of said outer frame, said inner frame and a bag having its open end extending through the opening of said inner frame and clamped between said inner and outer frames.
Claim 2
Dependent Claim
163 words
A bag handling system comprising: an inner frame defining a central opening therethrough; an outer frame of channel-shaped cross-section and having a shape corresponding to the shape of said inner frame so that said inner frame can fit within the channel of said outer frame; a hand grip rigidly joined to said outer frame; releasable locking tabs provided on said outer frame for holding said inner frame within the channel of said outer frame, said locking tabs extending partially into the channel of said outer frame; and rails rigidly joined to and extending along said outer frame on both sides of said hand grip, said rails serving as a means of releasably attaching an extension handle to said outer frame on either side of said hand grip to facilitate manipulation of an assembly of said outer frame, said inner frame and a bag having its open end extending through the opening of said inner frame and clamped between said inner and outer frames.
Claim 3
Dependent Claim
16 words
The bag handling system as defined in claim 1, wherein said rails are of T-shaped cross-section.
Claim 4
Dependent Claim
52 words
The bag handling system as defined in claim 1, further comprising an elongated extension handle having a hand gripping formation at one end and a formation at the other end configured to couple with one of said rails to thereby effect a releasable attachment of said extension handle to said outer frame.
Claim 5
Dependent Claim
72 words
The bag handling system as defined in claim 1, further comprising a guide tray which is releasably attachable to said outer frame, said guide tray comprising a guide surface which is inclined when said guide tray is attached to said outer frame and said outer frame is vertically oriented, said guide tray thereby facilitating the sweeping of items into the open end of a bag clamped between said inner and outer frames.
Claim 6
Dependent Claim
33 words
The bag handling system as defined in claim 4, wherein wall-mounting holes are provided in said guide tray, said holes being spaced to receive fasteners secured to adjacent studs in a vertical wall.
Claim 7
Dependent Claim
45 words
The bag handling system as defined in claim 1, further comprising legs which are releasably attachable to said inner frame, said legs, when attached to said inner frame, serving to stabilize said inner and outer frames, assembled together, against a horizontal or vertical support surface.
