Fig. 8 is a cross-section taken on line 8-8 of 50 Fig. 7, the latch being in the position of Fig. 6.
A pair of back members I and 2 are mounted for sliding movement relative to each other between sheet binding and extended positions, as illustrated in Figs. 3 and 3 respectively. Outer baci; member i is provided with a pair of guide channels arranged one at each end o the back member to slidably receive guide rails il on the ends oi inner back member 2. Guide channels 3 and rails i are provided with interengaging stop members 5 for normally retaining the back members against complete detachment at an outer limit of sliding movement defining the extended position of the back members. Outer baci: member l is formed of an angular metal baci: plate 5 having a ange "l forming a binder bar. Suitable cover material 8 is applied over the inner and outer faces of back member t, with the use of filler as desired, and is also extended to provide the covering for cover member Q. Covering material 3 is arranged on back member l and cover 9 so that it will provide a hinge portion between cover 9 and the back member, as indicated at l0.
Back member 2 has a metal back plate i lY and a separate binder bar l2'y united by covering material i3 to form an angle back member, the covering material forming a hinge il between binder bar i2 and cover i5 over which it extends, as shown for example, in Figs. 2 and 7. With this construction, binder bar l2 is hingeable at IS relative to the remaining portion of the back member formed by the covered back plate Il to facilitate the operation of the sheet-engaging posts in a manner that will be hereinafter described.
Inner back member 2 has two sets of sheetengaging posts I1 and I8 respectively, secured at one end to binder bar I2, and each having the opposite end extending inwardly toward the other back member in spaced parallel relation. In the drawings, two posts I1 are illustrated as arranged near opposite ends of' binder bar l2 and one post I8 is illustrated in the central portion of binder bar I2. It is to be understood that additional posts may be added to each set and arranged in spaced'parallel relation for engaging in perforations` in the binding edges of a plurality of loose leaf sheets, in a manner well-known in the art. Posts I1 are of'tubular construction and are internally threaded to threadedly receive extensible post sections I9, having a latch engaging member on the free end of each extensible post section. Sheet-engaging post I8 is of tubular form, as clearly illustrated in Figs. 3 and 8.
A transfer bar 2| is provided with acentral post 22 for-slidable engagement in tubular post I and tubularv posts 22` positioned thereon to receive posts I1 in slidable relation therein. Extensible post sections i9 are arranged to slide in posts 23 so that latch-engaging member 2E# on each section will extend through apertures in the transfer bar for engagement by the latch mechanism to be described. Transfer bar 2l has a pair of latchengaging members 24 mounted thereon in positions intermediateposts 22 and 23 and extending outwardly for engagement-with the latch mechamsm.
The latch mechanism is mounted on outer bacia member I and has a channel member 25 secured to the outer face or" flange or binder bar i for cooperation therewith to provide a latch housing for slidably receiving latch bar 25. At the central portion, latch bar 25 is provided with an operating button 21 extending through a slot 23 in channel member 25, covering material 8 and "i position indicating plate 29 on the outside of the binder where it is accessible for manual operation to slide the latch bar back and forth into three different positions. The three positions are indicated on position indicating plate 2S, by numerals 1, 2 and 3, as shown for example in Figs. l and 6 where button 2 is shown in two different positions. Rivets 30, see Figs. 3 and 8 secure channel member 25 and binder bar 'i together in assembled relation and in addition, extend through slots 3l in latch bar 25 for guiding and limiting the sliding movement of the latch bar relative to the binder bar.
The end portions of latch bar 26 in alignment with posts Il and 23 are formed with keyhole slots 32 having the portion of smallest width at the left-hand end, as illustrated in Fig. 6 in a positioncorresponding t0 the first position or locked position of latch bar .2S and button 2l opposite the numeral l on position indicating plate 29. rilhe remainder of keyhole slot 32 is of greater width than the dimension of the head portions on latch-engaging members 2B, so that for the other two positions of latch bar 26, it will not be operative to have locking` engagement with latchengaging members 2&3. Therefore, whenever the binder back members are moved into a sheet compressing or bindingV position, latch-engaging members 2li will extend through keyhole slots 32 and post sections IQ are properly adjusted so that latch member 26 may be moved to the right, as shown in Figs. 6 andV 8 tohave the narrow portion or" slot 32 receiveV theA reduced portions 33 of latchengaging membersv 2li-for effectively latching the binder bars together'through the medium of posts ll and extensiblepost sections i9. In this position, the binder bars are held rigidly connected together against slidable movement of the back members relativeto eachother. When the parts are in this position, latch-engaging members 24 on transfer bars 2| will have the reduced portions 34 thereof extending through apertures in binder bars 1 andv into-keyhole slots 35 in latch bar 26 for engagement in the narrow portion ofy slots 35 in the manner shown in Fig. l. It will be noted that the narrow portion of slots 35 extends through both the first and second positions for latch bar 25 with the enlarged end arranged in the third'position only.
The above described construction ofl the latchmechanism therefore provides for the locking of the transfer bar and thebinder bar carried posts on binder bar l2 to binder bar 'I when latch bar 26 is inthe positionindicated by the numeral l in Fig. l. Fig. 1 shows latch member 26 and button 2l in the position described; The sheets engaged on the posts carried by the'transfer bar and binder bar l2 are thus held in compact or compressed bound relation with the binder bars retained against relative movement to'each other.
By moving button 2-'5- manually to a central po-- sition in slot 28fopposite the numeral 2 on position indicating plate 29, as shown in Fig. 6, latch bar 25 vwill bemoved into a positionso that latch-engaging membersV 20 carried by post sections i l' may be disengaged from binder bar 'l and latch member 2t through-the enlarged portions of slots 32. still retains latch-engaging members 24 in locked engagement with binder bar 'l so that transfer bar 2l may not be detached from binder back. member l. Under these` circumstances, back members I and 2 may be slidably moved apart from the sheetbinding position above described to the limit of movementprovided for by guide However, this position of latch bar 2E channels 3 and rails 4 until s top members 5 are engaged as shown in Figs.'4,'7 and 8. This retains the leaves carried by the several posts Il and I8 in loosely bound relation againstdetachment from the binder and provides for the separation of sheets, so that when the binder is opened and laid upon a nat horizontal surface, the sheets in the loosely boundA relation will lie substantially flat to provide for easy access'to information adjacent the bound edges.
Should it be desired to remove, insert or transfer sheets bound by the posts in the binder, then button 2l is manually operated into the position indicated by the numeral 3 on position-indicating plate 29. This will move the larger end of keyholel slots 32 and 35 into position to release latch-engaging members 20 and 24. As a result, transfer bar 2I may be disengaged from back member I and moved away from the back member into positions, as indicated in Figs. 4 and 5, in which the posts on the transfer bar and also the posts on binder bar I2 will be moved into an inclined position with respect to the bac-k member and binder bar I2 will be moved upon its hinge connection I6 relative to back plate II.
The transfer bar may then be disengaged from the telescoping arrangement of posts 22 and 23 with posts Il and I8 so that all, or any desired sheet or sheets, may be removed from engagement with the posts on the transfer bar and the posts I'I and I8. In addition, selective sheets may be removed frorn the binder by the manipulation of the sheets on the posts carried by binder bar I2 and the transfer bar. When the desired shifting, transfer, removal and insertion of sheets has been completed, the transfer bar then has its posts slidably engaged with posts I1 and I 8' in the manner illustrated in the drawings, when it may be moved into position relative to binding member I to engage latch-engaging members 24 in slots 35 for attachment to binder bar 'I through the operation of latch bar 26 to lock the transfer bar to the binder bar.
The invention, therefore, provides a binder having a post I arranged to provide for extension to receive and bind a sheet body of Variable size in which the binder bars may be rigidly connected together by posts I1 and extensions I9 thereof, to hold sheets in sheet-binding position. Then, through the release of one binder bar from posts I?, the back members may be moved into an expanded position through cooperation of the guide members so the binder may be laid upon a ilat surface with the covers in open position. Then the sheets may be moved apart in loosely bound relation and opened into position to lie substantially iiat and provide for convenient reference to all of the sheets in the binder.
The transfer bar provides for the convenient shifting and transfer of sheets in this binder construction when released from one binder bar, while at the same time, cooperating with the sheet-engaging posts on another of the binder bars to facilitate the support of the sheets in loosely bound relation. This cooperation between the transfer bar, the sheet-engaging posts, the latch means and the binder members, greatly facilitates the binding and reference to the sheets carried by the binder, as well as the convenient manipulation thereof to insert, remove and transfer the sheets.
The invention claimed is:
