7 Claims.
My invention relates more particularly to that type of binders which are termed analysis binders.
My invention has for its object to provide a new I and improved means of locking the binders for the loose leaves in position.
A further object is the provision of a novel construction for the binding posts which will tend to keep the sheet body in line and will materially assist in preventing the holes from being torn out of the sheet. It is'well known that this condition is one which is constantly present in all loose leaf binders and is a source of considerable annoyance.
By the use of my improvement it is largely lessened, if not entirely eliminated.
My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings which are hereunto annexed and made a part hereof, in which Fig. 1 is a plan view of my improved binder;
Fig. 2 is a section taken on the line 22 in Fig. 1 in the direction indicated by the arrows;
Fig. 3 is an end elevation of the binder as shown in Fig. 1;
Figs. 4 and 5 are detailed views of the recip rocable bar for disengagement of the lock;
Fig. 6 is an enlarged detail view of the locking mechanism;
Fig. 7 is an enlarged detailed view of one of the binding posts or pins, and
Fig. 8 is an end elevation with the binder in unlocked position.
Similar reference numerals refer to similar parts throughout the entire description.
As shown in the drawings, the binder comprises a U shaped member, the bottom part of the U being hingedly connected as at l, the sides 2 and 3 of the U may, if desired, be provided with extensions land 5 which are hingedly connected thereto although these extensions are not absolutely necessary and they need not be hinged. On the inside of the sides 2 and 3 of the U are secured two inwardly extended plates 6 and '7 which are arcuate in cross section. These plates are adapted to be telescopically intervolved one above the other as clearly seen in Fig. 3. The plate 6 is provided with a plurality of spaced apertures 8 and 9 which are adapted to receive lock bolts 10 and 11. lhis plate is preferably arcuate in cross section, this serving as a backing for the sheets. When so constructed it tends to prevent them from working on the posts and to keep 'T the perforations from being torn. These bolts 10 and 11 are suitably secured to flat springs 12, one end of which is secured by means of a rivet 13 to the lower plate '7. Apertures 14 are provided through which the lock bolts are projected by the tension exerted by the spring. The end 15 of each of the flat springs 12 is inclined as clearly seen in Fig. 6 and is adapted to be engaged by a correspondingly inclined surface 16, formed on a reciprocable bar 17 which is slidably secured to the lower surface of the lower plate 7. As illustrated rivets 18 are provided on plate '7 which are mounted in slots 19 and 20 which permit the bar 17 to be reciprocated.
The top of the posts 11 and 10 is beveled, as clearly seen in Fig. 6, towards the edge of the upper plate 6. This permits the edge of the upper plate to depress the bolt when the binder is being moved into closed position whereas if the bevel were omitted it would possibly strike against the edge of the locking bolt and would have'to spring over it but, by the provision of the beveled end, the plate very smoothly and conveniently depresses the bolt so that the plates telescope each other very uniformly until the bolts reach the apertures 8 and 9 and the spring projects the bolts into these registering apertures thereby locking the binder firmly in position. The binding posts or pins 21 are mounted on the inside of the sides 2 and 3 of the U alternately. Preferably these posts are arcuate when viewed in side elevation for convenience in holding the loose leaves in the binder when it is open. The free ends of the pins 21 are preferably pointed as at 22 to facilitate their insertion into the leaves to be bound. The body of the pins 21 is similar in size to the perforations in the loose leaves which are to be held in the binder. The base 23 of pins, however, is provided with an enlarged portion which is of greater diameter than the perforations in the leaves. as a backing for riveting the posts in position.
It has been found in practice that this device very satisfactorily accomplishes this result. Preferably the locking mechanism is enclosed by a cover 24 which extends the entire length of the binder so that the locking mechanism is completely enclosed.
Having described my invention what I regard as new and desire to secure by Letters Patent is-- 1. In a lose leaf binder, a U shaped member comprising two parts hingedly connected at the bottom of the U, a plurality of transversely extended alternate posts, secured to the sides of This serves the U, a reinforcing strip secured to each of said sides which terminates in an inwardly extending plate arcuate in cross section, said plates being adapted to be telescopically intervolved one above the other, there being a plurality of spaced openings in the top plate, a corresponding number of spring pressed locking members on the lower plate which project into such openings, a reciprocable bar secured to the underside of said lower plate, means on said bar to withdraw said looking members from engagement with the upper plate, the tops of said locking members being beveled whereby they will be depressed on contact with the edge of the upper plate. v
