Abstract

A self-closing bag holder has first and second resilient clamp plates which are connected by hinges on opposite ends to permit the clamp plates to bend outwardly with respect to each other. The hinged clamp plate assembly provides an expandable collar for supporting a plastic bag in an upright orientation. The sidewall of the plastic bag is fitted through the collar and is folded about the clamp plates in an open mouth configuration. The bag sidewall is secured to the bag holder by spikes formed on opposite ends of the clamp plates, and also by the interlocking union of a mounting bracket and handle assembly. Self-closure is provided by the resilient clamp plates which retract into engagement with each other upon release.

Claims

1. Bag holding apparatus comprising, in combination:

a first resilient clamp plate having first and second end portions;

a second resilient clamp plate having first and second end portions;

the first clamp plate being assembled on the second clamp plate with the first end portion of the first clamp plate being coupled to the first end portion of the second clamp plate, and the second end portion of the first clamp plate being coupled to the second end portion of the second clamp plate;

the assembly of the first and second clamp plates defining an expandable collar for engaging the tubular sidewall of a flexible bag; and

a mounting bracket assembled on said first clamp plate, said mounting bracket including a base plate adapted for attachment to an external support structure and having a retainer arm attached to said base plate in offset relation therewith, thereby defining an open slot in which said first clamp plate is received.

2. Bag holding apparatus as defined in claim 1, comprising:

a mounting bracket having retainer portions disposed in releasable, interlocking engagement with said first clamp plate;

a handle assembly having retainer portions disposed in releasable, interlocking engagement with said second clamp plate; and

latch means formed on said handle and said mounting bracket for releasably securing said handle in interlocking engagement with said mounting bracket.

3. Bag holding apparatus as defined in claim 2, wherein:

said first clamp plate having an inside surface facing said second clamp plate and having a channel formed transversely across the inside facing surface of said first clamp plate;

said second clamp plate having an inside surface facing said first clamp plate and having a channel formed transversely across the inside facing surface of said second clamp plate;

said mounting bracket having a base plate and a retainer arm mounted on said base plate in offset relation therewith, said mounting bracket retainer arm being received within the channel of said first clamp plate; and

,

said handle assembly including a base plate and a retainer arm mounted on said base plate in offset relation therewith, said handle retainer arm being received within the channel of said second clamp plate.

4. Bag holding apparatus as defined in claim 1, including:

a handle assembled on said second clamp plate for manually extending said second clamp plate relative to said first clamp plate; and

a releasable latch assembly attached to said handle, said latch assembly including a latch arm attached to said handle and detent means formed on said first clamp plate for engaging said latch arm in a releasable, interlocking union when the first and second clamp plates are in the closed position.

5. Bag holding apparatus as defined in claim 1,

said retainer arm having a shoulder rib projecting into said receiver slot for releasably retaining said first clamp plate in said receiver slot.

6. Bag holding apparatus as defined in claim 1, including:

bag piercing means formed on the first and second end portions of one of said clamp plates.

7. Bag holding apparatus as defined in claim 6, said second clamp plate including:

first and second hinge means formed on the first and second end portions of said second clamp plate, respectively, said piercing means projecting outwardly from said first and second hinge means.

8. Bag holding apparatus as defined in claim 4, including:

a mounting bracket having a base plate and a retainer arm mounted on said base plate in offset relation therewith, and said retainer arm having an edge portion engagable by said latch arm when the first and second clamp plates are in the closed position; and

said latch arm including a shoulder portion projecting transversely with respect to said latch arm, said shoulder portion being insertable into said receiver slot for interlocking engagement with the edge portion of said retainer arm.

9. A self-closing bag holder comprising first and second resilient clamp plates connected together in a hinged union at opposite ends, respectively, said resilient clamp plates being yieldably extendable outwardly with respect to each other to a bag open position and being retractable toward each other to a bag closed position, said clamp plate assembly providing an expandable collar for supporting a flexible bag in an upright collecting orientation, a mounting bracket having retainer portions disposed in releasable, interlocking engagement with the first clamp plate, a handle assembly having retainer portions disposed in releasable, interlocking engagement with the second clamp plate, the retainer portions of said mounting bracket and said handle assembly being adapted for securing sidewall portions of a flexible bag onto said first and second clamp plates, respectively.

10. A self-closing bag holder as defined in claim 9, including bag piercing means formed on at least one of said clamp plates.

11. A self-closing bag holder as defined in claim 9, including:

coacting latch means formed on said handle and said mounting bracket for releasably securing said handle in interlocking engagement with said mounting bracket when the clamp plates are in the bag closed position.

12. A self-closing bag holder comprising first and second resilient clamp plates coupled together at opposite ends, respectively, said clamp plates being yieldably extendable outwardly with respect to each other to an open position and retractable toward each other to a closed position, said clamp plate assembly providing an expandable collar for supporting a flexible bag in an upright collecting orientation, a mounting bracket attached to said first clamp plate, and a handle assembly attached to said second clamp plate;

said mounting bracket having retainer portions disposed in releasable, interlocking engagement with said first clamp plate; and

said handle assembly having retainer portions disposed in releasable, interlocking engagement with said second clamp plate.

13. A self-closing bag holder as defined in claim 12, said mounting bracket including a base plate adapted for attachment to an external support structure and having a retainer arm attached to said base plate in offset relation therewith, thereby defining an open slot in which said first clamp plate is received.

14. A self-closing bag holder as defined in claim 12, said handle assembly including a handle having a base plate and a retainer arm attached to said base plate in offset relation therewith, thereby defining an open slot in which said second clamp plate is received.

15. A self-closing bag holder comprising, in combination:

a first resilient clamp plate having first and second end portions;

a second resilient clamp plate having first and second end portions;

a first hinge assembly connecting the first end portions of the first and second clamp plates together for pivotal movement with respect to each other;

a second hinge assembly connecting the second end portions of the first and second clamp plates together for pivotal movement with respect to each other;

a mounting bracket having retainer portions disposed in releasable, interlocking engagement with said first clamp plate;

a handle assembly having retainer portions disposed in releasable, interlocking engagement with said second clamp plate; and

,

latch means formed on said handle and said mounting bracket for releasably securing said handle in interlocking engagement with said mounting bracket.
