Abstract

Two separate cover panels are mounted on two separate pliable laces to form a book structure with loose leaf pages mounted on the parallel lace portions which are between the cover panels. Each end portion of each lace lies longitudinally between and along the jaws of its own normally open, self-locking when closed and manually openable V-clamp. Two such clamps are carried on each cover panel; their fixed jaws constituting the end portions of a single slat; each such end portion having a well into which the companion movable jaw fits flush when the clamp is closed. In a modified embodiment, only one of the cover panels is provided with clamps, provision being made so that the lace ends at the other cover panel are headed to maintain their association with such clampless cover panel.

Other objects and advantages will become apparent as this disclosure proceeds.
For one practice of this invention, the intermediate parallel positioned portions of two pliable laces having some resilient quality, are for holding loose leaf sheets between two cover panels through which said laces are also passed. The fixed jaws of two V-clamps are mounted on each cover panel along the line of the holes in such panel, for holding the laces. Each fixed jaw has a companion movable jaw which is swingably mounted thereto by means of trunnion pintles extending laterally at one end of the movable jaw into aligned holes in the fixed jaw. The other end of each movable jaw has two spring fingers in extension thereof, provided with trunnion pintles adapted to automatically enter aligned holes in the fixed jaw when the clamp is closed, and thus releasably lock the clamp to grip a lace portion between and along the clamp jaws. The two fixed jaws on each cover panel are preferably integral to form a slat along the hole line of the associated cover panel. Eyelets which secure the slat to the cover panel, serve as the lace holes for the slat. Accessible tabs extending laterally from the spring fingers, when pinched together, release the movable jaw and so the clamp can be opened. Each fixed jaw has a well into which its companion movable jaw fits flush, when the clamp is set into closed condition. The holes for the two sets of pintles carried by the movable jaw, are in the side walls of such well. The laces are of course pulled through the clamps and made taut before the clamps are closed so the book-form effected, is tightly assembled. In a modified embodiment, clamps are only on one cover panel; the lace ends at the other cover panel being headed whereby the assembly is maintained.
In the accompanying drawing forming part of this specification, similar characters of reference indicate corresponding parts in allthe views.
FIG. 1 shows a binder embodying teachings of this invention. This view shows the binder in open condition, exposing the inner surfaces of the cover panels, and the laces connecting them; each end of said laces, being between the jaws of its own clamp; the clamps being shown in open condition. No pages are included in this view.
FIG. 2 is an enlarged fragmentary view showing the binder containing some pages, but the book is not tightened", so the pages are shown loose. The book is here shown upright, partially open, and in perspective.
FIG. 3 is an enlarged perspective: view of the movable jaw of one of the clamps.
FIG. 4 is an end view of FIG. 3.
FIG. 5 is a fragmentary perspective view, drawn to the scale of FIG. 3, showing one end of a slat mounted on one of the panels, there being one such slat on each panel, and each such slat end constitutes structure serving as the fixed jaw of a clamp.
FIG. 6 is an elevational view partly in section, showing an assembled clamp in open condition, drawn to the scale of FIGS. 3 and 5.
FIG. 7 is an end view of FIG. 6, but showing the clamp in closed condition, engaging a lace.
FIG. 8 is a fragmentary view, akin to FIG. 1, but of slightly modified form.
FIG. 9 is a bottom view of FIG. 3.
In the drawing, a loose leaf binder of preferred construction, designated generally by the numeral 15, consists of two cover panels 16 and 16' of relatively stiff material, laced through near one edge of the panel 16, and at the corresponding edge of the panel 16', by the spaced pliable separate laces L and L, which are for holding any desired number of loose leaf pages 20, between said cover panels; such pages having appropriate holes near one edge to receive said laces therethrough,
as is well known in this art. Each cover panel carries two normally open V-clamps whose cooperating jaws are adapted to releasably grip that region of a lace which lies along and between them. The lace parts which extend through the clamps, are denoted by the numerals 18,19 which are of the lace L, and l8, l9
which are of the lace L. The clamps on the cover panel 16, are indicated generally by the numerals 21 and 21 respectively, and those on the cover panel 16', are designated generally by the numerals 22 and 22' respectively. All clamps being of identical construction, the description of one, that numbered 21, will suffice for all.
The V-clamp 21, shown in open condition in the FIGS. 1 and 6, comprises an elongated movable jaw indicated generally by the numeral 23, along an elongated fixed jaw denoted generally by the numeral 24, which is mounted on the cover panel 16; said jaws being hingedly associated at one end to form a closable V-form whose mouth faces that off the clamp 21'. It is preferred that the fixed jaws of the clamps 21, 21 shall be integral and be the end regions of a slat 25. Likewise, the fixed jaws of the clamps 22, 22' shall be integral and be the end regions of the slat 25'.
The fixed jaw 24 of the clamp 2I, is provided with an indentation, which may be the well 26, or a channel by omitting the end wall 50, into which indentation, the movable jaw 23 fits flush, when the clamp 2] is closed, at which time the lace part 19 is gripped tight thereby. The opposite lengthwise walls of the well 26, or of the channel if such is used, not shown, have the aligned pair of holes 27, 27' for the respective pintles 28, 28' which serve as the axis of swing of the hinged movable jaw 23. Said opposite walls also have the aligned pair of holes 29,29 for the locking protruberances which may be the pintle- forms 30,30. The slat 25, at each end region, is secured to the cover panel 16 by the spaced eyelets 31 and 32, as shown. The indentations in the fixed jaws of the lace-clamping means 21, 21 are communicative with a longitudinal channel 33 of reduced width in the slat 25, which connecting channel is for the admission of the lace parts 19 and 19.
The movable jaw 23 of the clamp 21, has a clevis 34 at its hinged end, affording the pintles 28, 28' which fit into the holes 27,27 respectively, and thus provide the axis of swing of said movable jaw. The other end of the movable jaw, which is at the mouth end of the clamp, presents two spring fingers 35, 35', having lateral protuberances which may be the pintle- forms 30 and 30, which are adapted to become automatically engaged in the holes 29 and 29' respectively so the clamp 21 is self-locking when in closed condition. Each of said fingers, which are at the sides of the movable jaw, has an outward lateral tab 36, which set into the notches 37 respectively when the clamp is in closed condition. These tabs are accessible, and when manually pinched together, will release the engaged elements 30,30, so the movable jaw 23 can be manually swung to open said clamp 21, and thus release the lace part 19 which lies along the lengthwise channel 38 in the underside of said movable jaw 23. It is to be noted that the eyelet 31 is between the tines of the clevis 34 and has the lace L therethrough, thus mounting the panel 16 on said lace; said eyelet being in alignment with the holes in the pages 20, through which said lace is positioned straight.
One manner of presenting the binder in trade, is to have it assembled as shown in FIG. 1, except that all the clamps are closed after pulling the laces tight so that the cover panels are in superimposed relation. To mount pages 20, the binder is opened, then the cover panel 16 is removed after opening the clamps 21 and 21. Then the lace end 19 of lace L is set through one of the holes in said pages, and the lace end 19' of lace L is set through the other hole in said pages. Now, the lace end 19 is set through the eyelet 31, and between and along the jaws of the clamp 21, and pulled tight, whereupon the movable jaw 23 is shifted to close the clamp 21, and cause said clamp 21 to be locked because the pintles 30,30 will be sprung into the holes 29,29 respectively. The same manipulation is done with the clamp 21' It is evident that pages may be removed from or added onto the lace portions between the cover panels, from either side of the assembly, by opening the clamps 21,21 or 22,22 to remove the required panel 16 or 16', respectively, so proper access can be had to deal with pages, and then remounting such panel and effecting the book assembly. Obviously, removing pages from the book assembly would increase the length of either the lace ends 19, 19' if re moved from the panel 16 side or the lace ends 18, 18' if removed from the panel 16' side. Accordingly, adding pages to the book assembly would reduce the length of either the lace ends l9, 19' if added to the panel 16 side or the lace ends 18, 18 if added to the panel 16' side. It is noted that the amount of pages that could be added would depend upon the lengths of the associated lace ends, 19 19 and 18,18 which would permit proper gripping thereof by their respective clamps.
if it is desired to have the binder capable of having pages removed or added only from one side of the book, then, the cover member at that end of the book, shall be with clamps, but no clamps are furnished the other panel cover. Instead thereof, the lace ends at the clampless panel, shall be headed as shown at 40, which expedient will maintain the assembly; the single clamp for the lace L" being indicated at 42.
It is preferred that the clamps and the lace ends shall be out of sight and non-accessible when the binder 15 is closed, so as to avoid accidental opening of a clamp, and to add to the neatness and appearance of the binder. One manner to accomplish this is to have each cover panel provided along its entire height at back edge, with an extension hinged thereto at that edge forming part of a book back as indicated at 43. The associated slat 25, is along this extension on the back surface of the latter, and so positioned, that when the binder is closed, the back face of the cover panel 16, is across the mouths of the wells, and hence covers the movable clamp jaws 23, 23 residing in said wells.
Although to secure the book back portion 43 of the said extension, to the side edge of the slat thereat, it is more practical to have the extension comprise said part 43 and a flap 44, bent to be inside the binder, and to attach the said flap to the back of the slat by means of the eyelets 31 and 32, at each end portion-of said slat. It is evident, that the full extension shown forms a channel with its associated cover panel, in which the slat resides when the binder is closed. The numeral 45 indicates score lines to ease swing motion of the cover panel, which may be provided for such purpose. When the cover panels are made of sheeting material, their extensions to envelop the slats are made integral therewith respectively.
Recommended materials for the cover panels, are pressboard, plastic, cardboard which may be coated or cloth-bound, leather and the like. The laces are preferably of a pliable material having some resilient quality, as nylon, woven wire cable and the like. The slats 25, 25' are preferably molded of plastic, but may be of metal, pressed wood composition, or the like. The movable clamp jaws as 23, 23' are preferably mounted of plastic which would offer resilient quality to the resilient fingers 35,35, as polypropylene, or of suitable metal.
It is evident that a binder for tall pages, may have more than two laces and their appurtenant clamps, and that the binder may be made of such small size to accommodate tags which will be its pages, in which in stance, one lace may suffice. In some constructions, it may be desirable, that instead of the lace end being headed as at 40, it may be fixedly secured in proper place on the panel. It is believed that those versed in the art will readily understand all this, without the need of further illustration.
This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desired that the specific embodiments shown herein shall be deemed merely illustrative and not restrictive, and that the patent shall cover all patentable novelty herein set forth; reference being bad to the following claims rather than to the specific description and showings herein, to indicate the scope of this invention.
