Loose Leaf Binding Mechanism (Patent No: 364521)
Inventor: Easton, Alexander Borthwick Location: Calgary Comments: N/A Description: WHAT I CLAIM AS MY INVENTION IS:
(1) Improvements in loose leaf binding mechanisms comprising in combination with binder covers, an upstanding member attached to one of said covers, a stationary element attached to the other of said covers, said stationary element being provided with a member-receiving aperture therein, a rotatable element being provided with an obliquely disposed aperture therein, the edge of said aperture being designed to bind against said post upon the rotation of said rotatable element.
(2) Improvement in loose leaf binder mechanisms comprising in combination with an upper and lower cover, a post extending therebetween said post being attached to said lower cover, a post receiving aperture within said upper cover, a stationary element attached to said upper cover provided with a post receiving aperture therein, a rotatable member mounted upon said stationary element, said rotatable member being provided with an oblique aperture therein, the edges of said apertures being adapted to bind against said post upon the rotation of said rotatable member.
(3) Improvements in loose leaf binder mechanisms comprising in combination with an upper and lower binder cover, a post extending therebetween, said post being attached to the lower of said covers and extending through an aperture provided in the upper of said covers, a boss attached to the upper of said covers provided with an aperture therein, in alignment with said first mentioned aperture, a cap rotatably mounted upon said boss provided with an obliquely disposed aperture therein, the edge of said oblique aperture being designed to bind against said post upon the rotation of said cap.
(4) The device as claimed in claim 3 in which said upper cover, said boss, and said cap are each provided with alignable channels therein, said channels connecting with said apertures within the respective members.
(5) Improvements in loose leaf binding mechanisms comprising in combination with binder covers, an extensible and contractible post extending therebetween, means for rigidly attaching said post to one of said covers, a plurality of upstanding strips extending from said means, said strips being spaced to provide longitudinal apertures therebetween, further strips slideably mounted between said first mentioned strips and a post head attached to the upper end of said first mentioned strips, a post receiving orifice within the other of said covers, a boss mounted upon said cover provided with an orifice therein in alignment with said first mentioned orifice a cap upon said boss having an oblique aperture therein, the edge of said aperture being designed to bind against the head of said post upon rotation of said cap when said post is in a contracted condition.
(6) The device as claimed in claim 5 in which said second mentioned strips are provided with turned lugs at the end thereof, receivable within a recess at the lower end of said orifice within said boss.
(7) In combination in a device of the character herein described, binder post looking means comprising a stationary element mounted upon a binder cover, a rotatable member attached thereto, said rotatable member having an aperture therein, the edge thereof being designed to bind against a binder post upon the rotation of said rotatable member.
(8) Improvements in loose leaf binding mechanisms comprising in combination with binder covers, an extensible loose leaf binder post comprising means for attaching said post to one of said covers, interlocking means in association therewith designed to allow the extension or contraction of said post and means for securing a rigid post extension to said post.
(9) Improvements in loose leaf binding mechanisms comprising in combination with binder covers an extensible and contractible binder post comprising an element attached to one of said covers, a further element slidably mounted upon said first mentioned element and means for securing a rigid post extension to said post.
(10) Improvements in loose leaf binding mechanisms comprising in combination with binder covers an adjustable loose leaf binder post comprising means for attaching said post to one of said covers, a plurality of strips extending therefrom, said strips being positioned to provide longitudinal apertures therebetween, further strips slidably mounted within said apertures, means within said first mentioned strips for maintaining said second mentioned strips continually in alignment and an element attached to said second mentioned strips adapted to receive a rigid post extension.
(11) Improvements in loose leaf binding mechanisms comprising in combination with hinder covers an extensible and contractible binder post comprising means for attaching said post to one of said covers, strips attached to said means spaced to provide longitudinal apertures therebetween, further strips slidably mounted between said first mentioned strips, said second mentioned strips being maintained continually in alignment by means of a slidable element attached thereto and a further element' secured to the upper ends of said first mentioned strips, said element being adapted to receive a rigid post extension.
(12) Improvements in loose leaf binding mechanisms comprising in combination with binder covers, an upstanding member attached to one of said covers, the second of said covers being provided with an aperture therein designed to receive said member and rotatable jamming means mounted upon said second cover adapted to lock said second cover in any selected position alone; the length of said member.
