Abstract
Abstract A flexible post looseleaf binder having novel post hold-down slide means adapted to be easily inserted into and, if desired, removed from its retaining channel. To insert the slide means into the channel, the slide is held in a first angular position relative to the channel. In this position, the body of the slide presents to the channel top opening a maximum width not greater than substantially equal to the width of the channel opening, so that the slide can readily be inserted into the channel. After insertion, the slide is rotated to a second angular position. In this latter position, an abutment portion of the slide underlies a lateral wall portion of the channel, so that the slide is locked against accidental removal from the channel. In a modified form, each slide is provided with a hook-like hanger extension. When the slides are moved to the outward ends of the channel, these extensions protrude outwardly beyond the binder covers, and are used to hang the binder in a file cabinet or the like. Detent structure provided on each slide holds the slide releasably latched in the foregoing end position.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
190 words
In a looseleaf binder including spaced wall means defining therebetween a longitudinally extending space and a top opening thereinto, said wall means including laterally extending wall portion means: a slide member adapted to be slidably disposed in said space for sliding longitudinal movement therealong relative to said spaced wall means; said slide member including a body portion which in a first angular position of said slide member relative to said opening presents to said opening a maximum width not greater than substantially equal to the width of said opening to thereby permit said body portion to be inserted through said opening into the space defined between said spaced wall means; said slide member after insertion thereof into said space being rotatable relative to said opening to a second angular position; said body portion of said slide member including abutment means rendered effective by said rotation of said slide member to said second angular position to underlie said laterally extending wall portion means, said wall portion means cooperating with said abutment means, when said slide is in said second angular position, to block said slide means against removal from said space.
Claim 2
Dependent Claim
190 words
In a looseleaf binder including spaced wall means defining therebetween a longitudinally extending space and a top opening thereinto, said wall means including laterally extending wall portion means: a slide member adapted to be slidably disposed in said space for sliding longitudinal movement therealong relative to said spaced wall means; said slide member including a body portion which in a first angular position of said slide member relative to said opening presents to said opening a maximum width not greater than substantially equal to the width of said opening to thereby permit said body portion to be inserted through said opening into the space defined between said spaced wall means; said slide member after insertion thereof into said space being rotatable relative to said opening to a second angular position; said body portion of said slide member including abutment means rendered effective by said rotation of said slide member to said second angular position to underlie said laterally extending wall portion means, said wall portion means cooperating with said abutment means, when said slide is in said second angular position, to block said slide means against removal from said space.
Claim 3
Dependent Claim
50 words
The combination according to claim 1, wherein: said slide member includes a head portion disposed above said body portion, said head portion being disposed outside said space when said body portion is disposed within said space. said head portion providing a manually graspable operating means for manipulating said slide member.
Claim 4
Dependent Claim
21 words
The combination according to claim 2: said head portion being of a width greater than said top opening into said space.
Claim 5
Dependent Claim
44 words
The combination according to claim 3: said laterally extending wall portion means being provided at the top of said space and comprising opposed, spaced, laterally inwardly extending flanges, said top opening into said space being defined between the inner edges of said opposed flanges.
Claim 6
Dependent Claim
39 words
The combination according to claim 4: said slide member being provided with opposed, spaced, longitudinally extending slots adjacent and underlying said head portion; said slots opening laterally outwardly; said abutment means comprising a wall of each of said slots.
Claim 7
Dependent Claim
23 words
The combination according to claim 5: said flanges extending into said slots when said inserted slide member is in its second angular position.
Claim 8
Dependent Claim
24 words
The combination according to claim 1, including: means for blocking movement of said inserted slide member from said second to said first angular position.
Claim 9
Dependent Claim
33 words
The combination according to claim 1, wherein: said inserted slide member is rotatable from said second angular position to said first angular position to allow removal of said slide means from said space.
Claim 10
Dependent Claim
28 words
The combination according to claim 8, wherein said slide member includes: overridable means for blocking movement of said slide member from said second to said first angular position.
Claim 11
Dependent Claim
47 words
The combination according to claim 5, wherein said slide member further includes: opposed, spaced bar members depending below said slots and defining between said bar members a recess through which a post of said binder is adapted to extend and be held down by said slide member.
Claim 12
Dependent Claim
47 words
The combination according to claim 10, wherein: each of said bar members includes a vertical, substantially flat surface at an end thereof, the said surfaces of said two bar members being spaced and substantially parallel and defining thereacross said maximum width of said slide member body portion.
Claim 13
Dependent Claim
46 words
The combination according to claim 1, wherein: said slide member includes a substantially hook-shaped extension fast therewith and arranged to protrude outwardly beyond the side of said binder when said slide member is slid to a given position adjacent the end of said longitudinally extending space.
Claim 14
Dependent Claim
20 words
The combination according to claim 12, further including: positive latching means for latching said slide member in said given position.
Claim 15
Dependent Claim
19 words
