Patented Sept. 13, 1938 PATENT ortica 2,129,799 LoosE LEAF BINDER l ','Arthur E. viens, Hartford, Conn. Application June 29, 1996,vserial No. 89,895
` 12 claims; (01;,129-19 My invention relates to loose leaf binders. It has among its objects toprovide an improved binder of this type having anl extensible `back structure and capable of holding loose leaf iillers of widely varying thickness while presentingA a neat and attractive appearance at the back. A further object is to provide such an extensible binder having an improved flexible back. A still further object is to provide improved means for 105i securing the extensible back in various adjusted positions. Another object is toY provide such an extensible binder which results in a book of uniform thickness at the front and back regardless of the thickness of the ller. Other objects are -to provide an extensible loose leaf binder which is inexpensive to manufacture, which has a title bearing back portion that is constantly visible during the growth of the book, and a binder which is extremely simple in construction and in the manner of adjusting the back for various thicknesses of filler. Other objects and advantages of my improved binder construction will, however, hereinafter more fully appear.
In the accompanying drawing I have shown for purposes of illustration two embodiments which my invention may assume in practice.
In this drawing,-
Figure 1 is a perspective View of my improved binder looking toward the inside of the back;
Fig. 2 is a similar perspective view looking toward the outside of the back; y
Fig. 3 is a detail end view on an enlarged scale; Fig. 4 is a sectional view similar to Fig. 3; Fig. 5 is a detail on line 5-5 of Figure 3; Fig. 6 is a detail on line 6 9 of Figure 3, and Fig. 7 is a detail View showing a'modifiedr back construction.
- As herein shown, the loose leaf binder embodying my invention has the usual front and back covers I and 2,' including the parallel binder strips 3 and 4 disposed along the back edges thereof' which carry the usual binding posts 5 for holding the loose leaf filler (not shown).
Preferably the covers are formed of rigid bre `board covered with innerr and outer layers of fabric 6 and 1 which form hinges 8 at the junction of each binder strip in a well known manner to permit opening of the book. The posts 5, two of which are shown herein, each include' a main post member 9 which is inwardlyY extended through the binder strip of one of the covers, here the front cover I, and has an external thin head I0 which is secured permanently in position by the outer layer of fabric I which isy secured to Mathe cover by adhesive and envelops the hea-d I0.
The member 9 has a screw threaded recess II at its upper end into which is adjustably threaded either a binder screw I2 which is adapted to be inserted through an aperture I 3 in the back coveror a post extension I4 having a threaded recess IIa which similarly receives the screw I2. The post 9 can belengthened by the use of additional extensions I to accommodate llers of varying thickness, the binder illustrated having provision for using two such extensions.
VIn. accordance with my invention, an improved extensible back structure is provided for connecting the covers I and 2 which is preferably flexible in nature and which presents a smooth nonbulging back for the binder in various extended positions thereof to accommodate fillers of widely different thickness. To this end, the inner and outer fabric layers 6 and 'l of the front cover I are extended well beyond the binder strip 3 to form inner and outer flaps I5 and I6 which are substantially coextensive with the members 9 of posts 5. As shown in Figure 4, the free edges of the aps I5 and I6 are each provided with an inturned hem, a strip of stiifening material I'I alsobeing provided in the hem of the flap I 5 alongiits free edge. The flaps I5 and I6 are permanently secured together along their top and bottom edges I8 and I9, as shown in Figures 2 and 3, to provide, in effect, an envelope at the back of the binder of a width equal to the thickness of the binder when n.0 extension I4 is used on the posts 5.
The back cover 2 is provided with similar inner and outer flaps ZI) and 2i. The outer flap 2| is slightly reduced in length, as indicated in Figure 2, to. provide a tongue receivable between the iiapsy I5 and I6 of the front cover. The inner flap 29 overlies the inner surface of flap I5. It will thus be evident that as the posts 5 are extended to accommodate a thicker filler, the tongue 2I of the back cover telescopes in the envelope with the flap 29 adjustable relative to the envelope while continuing to overlap the same.
Improved means are also provided for securing,the back in various Yadjusted positions corresponding to different lengths of the posts 5, three such positions being herein provided for, although it will be understood that more may be provided if desired- To this end the iap member I5 of the front cover is provided with sets of snap members A, B` and C arranged in rows extending toward itsv free edge. Three of these sets are shown, herein, representing three different positions ofextension of the binder and located at 553,
suitable points on said flap member to cooperate with the single snap members D, one of which is carried by the inner flap 20 of the back cover for each set of snap members on the envelope.
In the drawing, the binder is shown in the intermediate position in which the snap member D of the back cover flap cooperates with the middle snap member B of each set carried by the front cover, one extension I4 being provided on each post member 9. It will be evident that if it is desired to use a thinner i'lller the extension I4 is removed and the binding screws I2 then cooperate directly with the screw threaded portions I l of the post members 9. In this position of the back structure, the snap members D would cooperate with the snap members C. However, if it were desired to accommodate a thicker filler, a second extension I4 would be screwed into that shown in Figure 4, and the snap members D would then cooperate with the snap members A. In any case it will be noted that the back of the book will remain substantially flat and that the title portion 22 remains visible, regardless of the degree of extension of the binder.
In Figure 7 I have shown a modified construction in which the inner flap member 20 of the back cover comprises the tongue and is received within the envelope formed by the flap members I5 and I6 of the front cover. Here it will also be noted that the sets of snap members A, B and C are carried on the inside of the flap 2| in position to cooperate with the single snap members D carried on the outer surface of the flap I6 adjacent the edge thereof. This construction, in
which the cooperating snaps can be adjusted after the clamping screws I2 are in place, is desirable in some cases. It will be noted that in this modified construction the projecting snap members D are not visible in any position of adjustment of the Vbinder and that the outer surface of hap 2| comprising the title portion of the back remains visible in all positions of adjustment.
In using my improved binder, the screws I2 are removed and the covers are opened up so as to lie flat with their inner faces up and with the posts 5 projecting upwardly. The loose leaves comprising the filler are then threaded over the posts 5. It will be noted that if it is desired to add sheets at the back of the book, as is usually the case, the sheets already in place on posts 5 need not be disturbed. When the sheets have reached the upper end of the post members 9 and it is desired to add more sheets, an extension I4 is screwed into the threaded end II of each of the post members 9 to accommodate additional sheets. If desired, one or more extensions may be added in a well known manner, the illustrative construction being limited, however, to the use of two extensions IB. When the required number of. sheets has been threaded on the posts 5, the snap members D are engaged with the cooperating snap members A, B or C, corresponding to the length of the posts 5, and the clamping screws I2 are again screwed into the posts to secure the iiller in place.
From the above description of my improvepansion of the binder does not require tools or difficult operations, and that the construction is simple and inexpensive and presents a binder which is always attractive in appearance.
While I have in this application specifically described two embodiments which my 1nvention may assume in practice, it will be understood that the invention may be modied and embodied in various other forms without departing from. its spirit or the scope of the appended claims.
