BACKGROUND OF THE INVENTION List finders, such as telephone indexes, comprise a plurality of stacked information cards having names, addresses and/or telephone numbers printed thereon. The cards are mounted on a holder, having a cover pivotally mounted thereon to selectively expose the cards for information gathering purposes. In order to obtain a selected telephone number, for example, an indexing pointer is moved along the cover and adjacent to a key letter whereupon the cover is opened to obtain the desired information.

The indexing pointer for a conventional list finder, such as the one shown in FIG. 6 of applicants drawings, is oftentimes mounted for sliding movements on a separate metallic bar secured to the cover. Such arrangement of the indexing pointer is expensive to manufacture and assemble and cannot be removed from the bar should replacement thereof be required. Additional prior art indexing pointers of this type are disclosed in US. Pat. Nos. 2,115,537; 3,192,658; and 3,405,466 and Swiss Pat. No. 345,871.

Conventional list finders are normally also accompanied by a separate memo pad. Such memo pad is normally utilized to jot-down notes during a telephone conversation, for example.

SUMMARY AND OBJECTS OF THE INVENTION An object of this invention is to overcome the above, briefly described problems by providing an economical, non-complex and substantially noise-free list finder which is adapted to have a flexible U-shaped indexing pointer expeditiously attached to an edge of its cover during assembly and positively retained thereon for noise-free and trouble-free operation by combined guide and locating means. The list finder further comprises a holder having the cover pivotally mounted thereon and a plurality of stacked information cards removably mounted in the holder. The cover preferably comprises a molded one-piece construction composed of a plastic material. A first indexing pointer embodiment is formed in a like manner whereas in a second such embodiment the pointer has a leaf spring attached thereon for indexing purposes.

Another feature of this invention comprises a receptacle formed in the holder to retain a stack of memo sheets therein, beneath the information cards.

BRIEF DESCRIPTION OF THE DRAWINGS Other objects of this invention will become apparent from the following description and accompanying drawings wherein:

FIG. 1 is a perspective view of a list finder, embodying this invention, shown in its closed condition;

FIG. 2 is a view similar to FIG. 1, but illustrating the list finder in its opened condition;

FIG. 3 is a longitudinal, sectional view of the list finder, taken along line AA in FIG. 1;

FIG. 4 is an enlarged, cross-sectional view through an indexing pointer of the list finder, taken along line A'A' in FIG. 1;

FIG. 5 is an isometric view of the indexing pointer;

FIG. 6 is a perspective view of a conventional list finder, shown in an opened condition; and

FIGS. 7 and 8 are views similar to FIGS. 4 and 5, respectively, illustrating a modification of the indexing pointer.

DETAILED DESCRIPTION FIG. 1 illustrates a telephone index-type list finder comprising a base or holder 1 having a cover or lid 2 pivotally mounted on a rearward end thereof in a conventional manner. Upon opening of the cover to its FIG. 2 condition, a plurality of stacked information sheets or cards 3, having stepped-down cut-outs sequentially formed on their edges, are exposed to divulge information such as names, addresses and/or telephone numbers imprinted thereon. The base defines a receptacle for removably mounting the cards therein and the cover has a downwardly extending outer guide bar integrally formed thereon to define a longitudinally extending and upwardly facing ledge or bearing surface 4 on a lower end thereof (FIGS. 2 and 4).

The holder and cover each preferably comprise a suitably composed and moldable rigid plastic material with the cover having a one-piece construction. The holder has an upwardly extending outer wall integrally formed longitudinally along its side (FIG. 4) which is parallel to the covers outer guide bar. When the cover is closed, its top surface assumes a substantially flush relationship with respect to the upper edge of the hold ers outer wall to fully protect the cover.

The information cards are individually exposed by selectively sliding an indexing pointerS along an edge of the cover. The pointer, shown disassembled in FIG. 5, comprises a molded, one-piece construction having a generally U-shaped cross section. As will be hereinafter more fully described, the pointer is preferably composed of a resilient and slightly flexible plastic material to permit the pointer to be detached from the cover for assembly and replacement purposes. I

Referring again to FIGS. 4 and 5, the pointer comprises a horizontally disposed base portion 6 having a vertically disposed side portion 7 integrally connected thereto by a pair of spaced ribs. An upper or pointer portion 8 is cantilevered on an upper edge of the side portion and has a line marking formed on a forward edge thereof for the visual indexing purposes hereinafter described. A pair of laterally spaced and upstanding positioning lugs 9 and 9' are integrally secured to the base portion.

A pair of parallel cut-outs 10 are formed through the base portion to define a cantilevered spring-like member 11. The base portion terminates at its opposite end at a card indexing portion 12 which underlies steppeddown cut-outs 3' formed on the edges of the cards, as shown in FIG. 4. A detent 13 is secured on the free end of member 11 to releasably snap into engagement with one of a series of longitudinally aligned indentations or recesses 14 (FIGS. 2 and 4) to provide spring-loaded detent means therewith. Upon selective movement of the indexing pointer along the cover, the detent means cooperates with card indexing portion 12 of the base portion to provide the indexing function.

Referring to FIG. 3, the forward end of the cover may be manually released from base 1 by depressing a bar 15 which is cantilevered on the base by means of a vertically disposed support member 16. A coil spring 17 is mounted between the support member and the base to aid in the latching and unlatching function, due to the inherent resiliency of bar 15 when the bar is flexed between its solid and phantom line positions shown in FIG. 3. An aperture 18 is formed in support member 16 to normally receive a locking lug l9 integrally formed on a forward edge of the cover to provide a latch means when the list finder is in its closed position.

As shown in FIG. 2, a pair of semi-ring shaped

binders

20 and 20 project through the cards to retain them in the list finder. As shown in FIG. 3, upon depression of bar 15 to release locking lug 19 from aperture 18, a torsion spring 21 cooperates therewith to provide opening means for automatically raising the cover to its phantom-line position. The base preferably has a rectangular receptacle formed therein to retain a plurality of stacked memo sheets 22.

Thus, when the pointer is moved downwardly to its extreme position towards a forward end of the cover in FIG. 1, opening of the list finder will expose the memo sheets for use during a telephone conversation, for example. As schematically illustrated in FIG. 1, indicia means 23 may be formed on the cover to selectively align pointer portion 8 of the indexing pointer therealong for accurate information gathering purposes.

As clearly illustrated in FIG. 4, the cover has a longitudinally and downwardly extending inner guide bar 24 integrally secured thereon in parallel relationship to the outer guide bar. The inboard side of the inner guide bar abuts opposed flat bearing surfaces of lugs 9 and 9' to guide and prevent rightward movement of the indexing pointer relative to the cover and to precisely position card indexing portion 12 of the indexing pointer under the cards. As will be hereinafter described, the lugs have a height which is sufficiently short to release them from their abutment with the inner guide bar upon downward flexing of base portion 6.

Ledge 4 engages the lower end of side portion 7 of the indexing pointer in bearing contact to precisely locate detent 13 in a particular indentation 14, formed on the underside of the outer guide bar of the cover. The above-described structures cooperate to provide a combined guide and locating means on the edge of the cover and on the pointer for permitting the pointer to slide smoothly along such edge and for normally preventing removal of the pointer from the cover.

As described above, the pointer is sufficiently flexible and suitable tolerances are provided between the pointer and cover to permit expeditious removal thereof laterally from the cover, when it is opened. Such removal is effected by merely flexing base portion 6 and cantilevered member 11 downwardly to slightly expand the pointer to release lugs 9 and 9' and detent 13 from the cover. A new pointer may be reinstalled on the cover in a reverse manner to replace a damaged or otherwise malfunctioning pointer by merely snapping the lugs and detent into their respective FIG. 4 positions.

In contrast thereto FIG. 6 illustrates a conventional list finder wherein a metallic indexing pointer 25 is slidably mounted on a metallic guide bar 26, secured by rivets 27 to a cover 28. Such a complex conventional construction is expensive and cumbersome to manufacture and does not provide the above-described replacement desiderata nor does it provide such noise-free and trouble-free operation.

FIGS. 7 and 8 illustrate a modification of the indexing pointer wherein like numerals depict corresponding constructions having similar functions. However, like numerals appearing in FIGS. 7 and 8 are accompanied by letters a to clearly identify modified constructions. The constructions illustrated are fully adaptable for use in the list finder illustrated in FIG. 1.

Indexing pointer 50, slidably mounted on the edge of a cover 20, pivotally attached to a holder 1a, comprises integrally connected base, side and pointer portions 60, 7a and 80, respectively. A pair of lugs and 9a abut the inboard surface of an inner guide bar 240 whereas a card indexing portion 12a of base portion 60 underlies stepped-down cut-outs 3 of information cards 3 for indexing purposes. A groove 29 is formed longitudinally along the underside of pointer portion 8a to receive an upwardly facing positioning tongue 30 formed longitudinally along the upper edge of the cover. Such tongue and groove arrangement normally prevents the pointer portion from moving laterally relative to the cover.

The groove defines a downwardly facing ridge 31 on the pointer portion which engages the top of the cover in bearing contact therewith. A downwardly facing bearing surface 32, disposed vertically downwardly from groove 29, engages an upper bearing surface of ledge 4a of the cover to aid in the guiding and locating function. A pair of raised, parallel bars 33 and 33' are formed integrally on base portion 6a and terminate at their forward ends, short of side portion 7a to define a recess therein.

A leaf spring is clamped on the base portion in such recess means and has a V-shape, terminating at its apex in an upwardly facing detent 13a to provide a spring-loaded detent means therewith. The detent, as shown in FIG. 7, sequentially engages an indentation 14a for retaining the indexing pointer in a chosen position along the cover for indexing purposes. From the above description it can be seen that lugs 9a and 9a, groove 29, ridge 31, surface 32, ledge 4a and the tolerances provided between the indexing pointer and the cover also provide combined guide and locating means. Also, the pointer may be assembled on or removed from cover 20 by merely flexing it into a slightly expanded condition to release lugs 90 and 9a, ridge 31 and detent 13a from the cover.
