'5I a calendar of the wall type having a binding and locking arrangement of new and improved construction.

A more particular object of the invention is to perfect a calendar of the loose-leaf type having binding means for the leaves of the calendar which means also serves as part of a locking means for the cover of the calendar.

Another object is to perfect a loose-leaf calendar of the wall type having a back cover and a front cover, binding elements secured to the back cover for suspending the leaves of the calendar below the covers, and means on the front cover cooperating with the binding elements to form locking means readily disengageable to permit a leaf to be turned and hidden underneath the front cover, and readily engageable to lock the cover to hold the leaf in turned position.

Other objects and advantages will become apparent from the following detaileddescription taken in connection with the accompanying drawing, in which:

Fig. 1 is a perspective view of a calendar embodying the features of the invention, showing the front cover of the calendar raised to permit the turning of a leaf of the calendar.

Fig. 2 is an enlarged fragmentary front elevational View, partially in elevation and partially in section, of the calendar shown in Fig. 1.

Fig. 3 is an enlarged fragmentary sectional view taken approximately along the line 3-3 of Fig. 2.

Fig. 4 is a view of the same proportion as Fig. 3, taken approximately along the line 5-5 of Fig. 2 but showing the front cover just engaging the binding elements.

Fig. 5 is an enlarged sectional View takenl approximately along'the line 5 5 of Fig. 2 and showing the front cover fully engaged or locked with the binding elements.

While the invention is susceptible of various modifications and alternative constructions, it is here shown and will hereinafter be described in apreferred embodiment, but it is not intended that the invention is to be limited thereby to the specific construction disclosed, but it is intended to cover all modifications and alternative constructions falling within the spirit and scope of the invention as defined by the appended claims.

Generallythe calendar is of the type intended to be hung on a wall and is also of the type in which 1938, Serial No. 226,056

(Cl. Ll-119) the leaves of the calendar are intended to be employed for record purposes, and thus are to be saved and not torn off and thrown away after the month represented thereon has passed. Accordingly, the calendar comprises aback cover I0, a front cover II and a plurality of leaves I2. The covers as well as the leaves are of rectangular shape having'their horizontal dimension greater than their vertical dimension, and with the leaves I2 both slightly shorter and slightly narrower in I0- ord'er that they may be received between the covers Ill and I I, and when so received completely concealed between the covers. The front cover Il is hingedly connected at its upper end to the upper edge of the back cover IB, While its lower edge is free, in fact, the covers I0 and II preferably are formed, as shown in Figs. 1 and 2, from a single piece which is bent midway of the longitudinal edges of the covers to form the hinged connection between the covers. If desired, an aperture I3 may be formed in the covers near the upper edges to receive a hook or nail by means of which the calendar is hung.

A unique binding arrangement is provided herein which serves not only as a means for securing the leaves in loose-leaf manner to the back cover, but also forms part of a locking means for the lower edge of the front cover. To that end, the back cover Il) near its lower edge is formed with a pair of closely spaced apertures I4 adjacent each end of the cover. Similarly, each leaf I2 is formed with a pair of apertures I6 formed in the leaves near the top edge and adjacent each end of the leaf. Adapted to be threaded through the apertures in the back cover l and the leaves I2 is aremovable binding element, generally designated I'I. In the present instance, this element comprises a pair of rings I8 secured together by a connecting portion I9. Each of the rings has its free end overlapping the 40 connecting portion, as best seen in Figs. 3 to 5,V and is resilient to permit the opening of the ring by vdistortion so as to permitl its being threaded through the apertures I4 and I6. 'Ihis l binding element preferably is formed of plastic material, but may be formed of other materials having the desired degree of resiliency.

It :is believed apparent from the foregoing descriptionv that the leaves I2 are normally suspended below the cover portions III and Il, as 505 best shown in Fig. 1. When the end of a month or other unit of time represented on each leaf has been reached, 4.the leaf may be turned upwardly so as to be received between the front and back covers, thus to be preserved for future reference 5'53- and at the same time to be concealed from view. Such turning of a leaf is readily accomplished simply by lifting the front cover II.

In order that the front cover I I may retain the leaves which have been turned between it and the back cover, and in order that the Weight of such turned leaves may not open the front cover a sufficient distance to permit the leaves to fall down, means is provided on the front cover for cooperation with the binding elements I'I forming a readily engageable and disengageable locking means for retaining the front cover II in closed position. This means comprises simply a pair of T-slots 20 formed in the front cover in the lower edge thereof and opening through the lower edge thereof. These slots are spaced to correspond with the apertures I4 and, as best seen in Figs. 3 to 5, provide a plurality of tabs 2| which cooperate with the binding elements I'I to form the locking means for the front cover. If it is found desirable, in order to provide sufficient strength and life, the tabs 2|-may be reinforced in rsome way.

As best seen in Fig. 4, when the front cover I| is to be engaged with the binding elements I'I, it is simply pressed onto the binding elements and as a result of the pressure so applied the tabs 2| are bent, as shown in Fig. 4, permitting them to pass by the ring members I8.` After passing the l ring members I8, the tabs, due to their resilient construction, straighten out and thus lock behind the ring members I8, as shown in Figs. 3 and 5. When so locked behind the ring members I3, the front cover Il 'is so well secured that the weight of the leaves .which 'have been turned and which are retained between the front and the back covers will not be suiicient to cause the cover I I to open a distance sufcient to permit the leaves to drop down. When it is desired to turn a leaf, the front cover is simply pulledoutwardly at its lower edge, at which time the tabs 2| will be bent oppositely to the manner shown in Fig. 4 and will permit disengagement of the tabs and the binding element. With the cover disengaged, a leaf I2 is turned upwardly and positioned, as shown in Fig. 1, between the covers I0 and I I and the front cover I I is then again closed, and the tabs 2| pressed into engagement with the element II to lock 4the cover. It is believed apparent that for mailing purposes all of the leaves I2 are turned upwardly so as to lie between the covers III and I I, thereby making a compact mailing piece.

In view of the foregoing, it is believed apparent that I have perfected a new and improved calendar of the loose-leaf wall type and, more particularly, have perfected a new and improved binding and locking arrangement for such a calendar. When constructed in the manner disclosed herein, the `leaves l2 are readily and quickly turned without removing the calendar from its supporting hook or without requiring much time or effort in the manipulation of fastening or securing means. Yet the construction provided herein assures that the leaves will be retained in turned position and will not fall of their own weight, and also assures that the calendar may be folded intov a compact piece for mailing or preserving purposes.
