Abstract
Abstract A collapsible door wedge characterized by: a channel shaped base member; a channel shaped incline member pivotally attached at one end to an end of the base member; a prop member pivotally attached to the other end of the base member; and a quick release latch mechanism attached to the incline member for retaining the prop member in its propping position. The incline member has a lower surface provided with a pair of downwardly extending stops defining a latching space receptive to an end of the prop member. The latch mechanism includes a shaft extending through a chamber of one of the stops, a striker attached to one end of the shaft, a knob attached to the other end of the shaft, a washer for supporting the latch mechanism, and a spring disposed around the shaft for biasing the striker towards the latching space.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
126 words
A collapsible door wedge with quick release mechanism comprising: an elongated base member; an elongated incline member having a lower surface provided with a pair of downwardly extending stops defining a latching space therebetween; means pivotally coupling a first end of said base member to a first end of said incline member whereby said incline member may pivot between a wedging and a non-wedging position; a prop member having a first end pivotally coupled to said base member and a second end configured to fit within said latching space; and a latch mechanism coupled to said incline member including a striker biased towards said latching space and adapted to engage said prop member when said second end of said prop member is within said latching space.
Claim 2
Dependent Claim
126 words
A collapsible door wedge with quick release mechanism comprising: an elongated base member; an elongated incline member having a lower surface provided with a pair of downwardly extending stops defining a latching space therebetween; means pivotally coupling a first end of said base member to a first end of said incline member whereby said incline member may pivot between a wedging and a non-wedging position; a prop member having a first end pivotally coupled to said base member and a second end configured to fit within said latching space; and a latch mechanism coupled to said incline member including a striker biased towards said latching space and adapted to engage said prop member when said second end of said prop member is within said latching space.
Claim 3
Dependent Claim
77 words
A collapsible wedge with quick release mechanism as recited in claim 1 wherein a first of said pair of stops includes an internal chamber, and wherein said latch further includes a shaft extending through said chamber, a knob attached to a first end of said shaft, and biasing means disposed within said chamber for biasing a second end of said shaft towards said latching space, where said striker is attached to said second end of said shaft.
Claim 4
Dependent Claim
44 words
A collapsible wedge with quick release mechanism as recited in claim 2 further comprising support means coupled to said incline member proximate said chamber, and wherein said biasing means includes a spring, said support means providing a shoulder against which said spring may bear.
Claim 5
Dependent Claim
40 words
A collapsible wedge with quick release mechanism as recited in claim 3 wherein said knob is provided with a planar surface that is guided by a planar surface of said incline member to prevent rotation of said shaft and striker.
Claim 6
Dependent Claim
39 words
A collapsible wedge with quick release mechanism as recited in claim 2 wherein a second of said pair of stops includes a substantially vertical face facing said latching space, and an inclined face facing away from said latching space.
Claim 7
Dependent Claim
30 words
A collapsible door wedge with quick release mechanism as recited in claim 5 wherein said prop member has an upper surface provided with a first recess receptive to said striker.
Claim 8
Dependent Claim
40 words
A collapsible door wedge with quick release mechanism as recited in claim 6 wherein said prop member has an upper surface provided with a second recess receptive to said second stop when said incline member is in said non-wedging position.
Claim 9
Dependent Claim
40 words
A collapsible door wedge with quick release mechanism as recited in claim 7 wherein both said first end and said second end of said prop member are rounded from said upper surface toward a lower surface opposing said upper surface.
Claim 10
Dependent Claim
26 words
A collapsible door wedge with quick release mechanism as recited in claim 8 wherein said base member and said incline member are nestling, channel shaped members.
Claim 11
Dependent Claim
74 words
A collapsible door wedge with quick release mechanism as recited in claim 9 wherein said incline member includes an endwall portion at said first end provided with a transverse bore and a pair of slots engagable with the sidewalls of said channel shaped base member, and wherein said hinging means includes a pivot shaft extending through the bore of said endwall and engaging bores provided in said sidewalls of said channel shaped base member.
Claim 12
Dependent Claim
22 words
A collapsible door wedge as recited in claim 10 further comprising means for attaching said base member to a flat, horizontal surface.
