UNITED STATES JAMES D, DOUGLAS, OF DETROIT, MICHIGAN.
Application filed October 30, 1926. Serial No. 145,123.
This invention aims to provide a portfolio having the inner ends of its cover members connected by an element on the inner side of which latter a binder support is secured, and to provide binders any one of which may be readily mounted on orremoved from the binder support so that the maufacturc of ortfolios may be cheapened and simplified and also to provide a portfolio into which any one of a variety of binders with their sets of leaves may be inserted.
Another object of the invention is to [no vide a portfolio having a binder support secured therein which has holding means for supporting a binder in such a manner that the latter cannot become detached from its support without positively releasing the holding means, and simultaneously exerting pressure on the binder itself.
With these and other objects in view which will become apparent as the specification proceeds, the invention is hereinafter more fully described with the aid of the accompanying drawings, in which:
Figure 1 is a general view of a portfolio, and
Figure 2 illustrates the same portfolio being utilized as a stand.
Figure 3 is a partial View of the invention showing the binder support.
Figure 4 shows the side of a binder and binder support, and the element by which the side members are connected in section.
Figure 5 is a partial View of a binder. and
Figure 6 is a section on the line VI--VI of Figure 3.
Referring to the drawings, 1 designates a portfolio having cover members 2 and 3 connccted at their inner ends by an element 4;. To the latter a binder support 5 is attached as by rivets 6. Integral with the binder support are forwardly projecting loops 7, and the upper end of the support cut away at 8 to permit the forwardly flexed end 9 ot the spring 10 to project between the upper margins 8 of the support. The lower end. ot the spring terminates between the inner surface of the element 4; and the back of the binder support 5, and held in position by one of the rivets 6 employed for connecting the binder support to the cover element 4.
The binder 11 is usually substantially channel-shaped insectiou, so that the leaves 12 may be secured in any desired manner between the opposite sides 11 of the binder; and the central portion 11 of the binder,
It will be noted that the fingers 14 are so positioned that when they are fully in engagement with the loops 7 that the upper end of the central portion ll of the binder is immediately beneath the forwardly flexed end 9 of the spring 10, so that should pressure be exerted under the binder the latter will not become disengaged from its support unless the forwardly flexed spring end 9 is snnultaneously depressed.
ln Figures 1 and 2 the portfolio 1 de plcted is of the type on which the construction hereinbefore described is utllizedi though obviously variations may be made in the cover member construction. In the portfolio 1 one of the cover members 3 has a flexible portion 15 thereon which is. of sufiicient length to fold around the outer edges of the leaves 12. At the other end of the flexible portion is a flap 16 which is in turn secured to an extension 17 by a joint 18. The cover member 2, the flap 16, and the extension 17 are provided with fasteners 19 so that the portfolio may be secured either in open position as indicated in Figure 2 or in closed position. I
On account of the fastening means between the binder support and the binder supporting the latter towards both its ends the cover members 2 and 3 may be turned downwards into the position indicated, in Figure 2 without an} danger of impairing the cilicacy of the fastening means. It will also he noted that this construction permits of several binders being carried and successively mounted in the one portfolio, thereby minimizing the amount of equipment that a salesman need carry with him.
lVhile in the foregoing the preferred em bodiment of the invention has been described and shown it is understood that the construction is susceptible to such modifications as fall within the scope of the append-edelaims.
What I claim as my invention and desire to secure by Letters atent is:
1. A portfolio comprising a cover, a sup porting plate connected to the cover, a binder including a member superposed on and in contact with said supporting plate, one of said contacting members having an integral loop projecting from its inner face and the other said member having a tongue projectlng from its mner face and extending through said 100p, and means for preventing relative movement between the supporting plate and binder tending to Withdraw the tongue from the loop.
2. In a portfolio, the combination with a cover and a binden of means for detachably connecting the cover and binder comp 'ising 1 a supporting plate secured to the cover and making surface contact with a portion ot the hinder, the contacting members of said plate and binder having interengaging means and a leaf spring extending between said members and secured to one of then'n a portion of said spring engaging the other said member to normally prevent disengagement of said interengaging means.
