SHEET 5 OF 5 CARD INDEX WITH SELECTING MEANS This invention relates to a card index of the type described in a patent to W. Koller, US. Pat. No. 3,423,862, which comprises a case, a drawer biased by a push spring and held in a closed position by a latch, the drawer adapted to accommodate a plurality of index cards with reference numbers, letters and so on, means for unlatching the drawer and releasing an index card selected by means of a set key by urging the unlatched drawer outwardly under the action of the push spring, the rear side of the drawer being open and the base of the drawer having parallel longitudinal slots for accommodating snug-shaped cams mounted on the bottom of the box type case at a predetermined distance from a case aperture, the predetermined distance corresponding, in the pushed-in position of the drawer, to the length of a drawer base portion which slopes towards the drawer front wall and defines a recess, an entrainment member on each longitudinal edge of the drawer adapted to engage matingly shaped entrainment recesses in the index cards of a resiliently elastic material, each of the index cards having at its adjacent front face register type selector recesses for engagement by the selector keys operating the latch for locking the drawer in such a way that when a selector key is depressed a selected index card, with any stack of index cards lying below it, is bent down over the cams and pressed into the recess and onto the entrainment members of the drawer whereby the latch is tilted from its locking position.
The object of the present invention is to improve the card index of the above-mentioned patent and to provide an improved card index in which any error in the selection of the index cards is excluded and the possibility of damaging the front faces of the index cards having the selector recesses is avoided. This object is attained in accordance with the present invention in that in a card index of the above-described type a guide cam is mounted on the bottom of the case, centrally with respect to the longitudinal extension of the drawer and to the rear of the recess defined by the sloping drawer base portion, the guide cam height increasing in the direction of the rear of the drawer, the guide cam adapted to cooperate with a groove in the drawer base extending transversely to the longitudinal direction of the drawer, the groove adapted to receive an U-shaped swivel stirrup having free leg ends pivotably mounted at the longitudinal side walls of the drawer, and a central portion bent towards the base of the drawer and received in a central opening of the groove, the central stirrup portion adapted to cooperate with the guide cam so that in the pushed-in position of the drawer the stirrup is in a raised position and the index cards are lifted at their front faces andthe entrainment recesses of the index cards are moved out of the engagement range of the entrainment members located in front of the recess defined by the sloping drawer base portion.
For additionally accommodating a supply of notice material the base of the drawer includes two adjacent cup shaped recesses separated by a channel shaped fillet for guiding the guide cam, a rear support surface and a front support surface for supporting the index cards, the groove for receiving the stirrup being provided in front of the recess into which will be depressed the selected index cards, with any stack of index cards lying below them when depressing a selector key. The
two support surfaces of the drawer base are connected by longitudinal side walls of the drawer laterally defining the cup shaped recesses, and the upper edges of the side walls lie in the same plane as the two support sur' faces.
The entrainment members are spaced from each other and mounted on the base of the drawer between the groove and the recess in the base, and'the index cards have entrainment recesses, each of which is operably associated with a corresponding one of the entrainment members.
For protecting the front faces of the index cards when pushing the drawer into the case, the two longitudinal side walls of the drawer are provided, according to another feature of the present invention, with a reduced portion to the rear of the stirrup and between each of the higher and lower longitudinal side wall portions forming a step-like vertical entrainment shoulder, the index cards having recesses in the region of the higher longitudinal side wall portions corresponding to the lengths and related to the thickness of the longitudinal side wall portions. Furthermore, the selector recesses of the various index cards of the stack which are provided at the front faces of the index cards are arranged in a step-like fashion from the left and from the right longitudinal side edges towards the entrainment recesses and from the centers of the index cards towards the entrainment recesses.
An example of an embodiment of the invention is illustrated in the drawing and described in more detail in the following. In the Figures:

FIG. 9 is a top viewof several superimposed index cards of the type shown in FIGS. 8 and 8A;
FIG. 10 shows the card index partly in perspective and partly in section; 7
FIG. 11 is a partial longitudinal sectional view of the card index; and
FIG. 12 is a perspective view, partly in section, of a portion of the card index.
In a preferred embodiment shown in FIG. I the card index constructed in accordance with the invention consists of a case 4 with a drawer 2, open at the rear end and guided on the bottom 4a of the case, for accommodating a plurality of index cards 1 of a resiliently elastic material. The index cards 1 are provided with entrainment recesses 15 adjacent to their front faces. The front faces of the index cards 1 which are advanced when the drawer 2 travels outwardly have selector recesses 20 which extend stepwise from the left and from the right longitudinal side edges of the cards towards the entrainment recesses 15 and from the centers of the index cards 1 towards the entrainment recesses 15. The stepped arrangement of the index cards 1 which are successively referenced from a to i is preferably such that, commencing from the top of the stack, the left hand steps are formed by the first card a, the third card c, the fifth card e and the eleventh card k, the right hand steps are formed by the second card b, the fourth card d and the sixth card f, the center left hand steps are formed by the first card a, the seventh card g, the ninth card i and the twelfth card 1, and the center right hand steps are formed by the second card b, the eighth card It, the tenth card j and the twelfth card 1 respectively (FIGS. 8, 8A and 9).
A guide cam 50 is mounted centrally on the bottom 4a of the case 4 and to the rear of a recess 16 which slopes towards the drawer front wall. The guide cam 50 is sloping upwardly towards the rear of the drawer 2 and is adapted to guide an U-shaped swivel stirrup 52 received in a groove 51 in the base of the drawer 2. The groove 51 extends transversely to the longitudinal direction of the drawer 2. The free leg ends 52a, 52b of the stirrup 52 are pivotably mounted at the longitudinal side walls 53, 54 respectively of the drawer 2. The groove 51 extends in the base of the drawer 2 up to points adjacent to the pivot mountings of the stirrup 52 (FIG. 1). The stirrup 52 has an approximately U- shaped central portion 55 which is bent towards the bottom 4a of the case 4 and is received by a central opening 56 in the groove 51 so that in the pushed-in position of the drawer 2 the U-shaped stirrup portion 55 rests on the highest portion of the guide cam 50, and the swivel stirrup 52 assumes a raised position in which the stirrup is raised upwardly by an amount corresponding to the amount of deflection of the central stirrup portion 55 from the plane of the stirrup towards the bottom (FIGS. 4 and The index cards 1 which are arranged on the base of the drawer 2 will be likewise lifted in the raised position of the swivel stirrup 52 so that the entrainment recesses of the cards are moved out of the engagement range of the entrainment members 6 which are located in front of the recess 16. These entrainment members 6 are spaced by about equal distances from the longitudinal side walls 53, 54 of the drawer 2, and from each other and engage the entrainment recesses 15 of the index cards 1 when actuating one of the selector keys (not shown) mounted on the case.
In the base of the drawer 2 are two adjacent eupshaped recesses 61, 62 for receiving blank notice slips 60 (FIGS. 1 and 2). These recesses 61, 62 are separated from each other by a channel-shaped fillet 63 extending in the longitudinal direction of the drawer. The closed upper surface of the fillet 63 serves as a support surface for the index cards 1 whereas the interior of the fillet 63 forms a guide track for the guide cam 50. The two recesses 61, 62 define in the base of the drawer 2 a rear support surface 64 and a front support surface 65 for the index cards I. The groove 51 for receiving the swivel stirrup 52 is provided in the front support surface 65. The recess 16 is in front of the front support surface 65. The cup- shaped recesses 61, 62 for accommodating blank notice slips or the like are bounded laterally by the longitudinal side walls 53, 54 of the drawer 2, and the upper edges of the side walls extend in the same plane as the support surfaces 65, 64. The index cards 1 are therefore supported by the two support surfaces 64, 65, the upper edges of the longitudinal side walls 53, 54 and the fillet 63.
The longitudinal side walls 53, 54 of the drawer 2 have a greater height in the front portion than in the remaining portion of the drawer. Each of the longitudinal side walls 53, 54 has a step-like portion defining an approximately vertical entrainment shoulder 53a, 54a approximately in the region of the swivel stirrup 52 (FIGS. 1 and 6). In the region of the higher portions of the side walls 53, 54 which extends up to the step-like shoulders the index cards 1 have recesses 70, 71 which correspond to the lengths of the higher front longitudinal side wall portions and are related to the thickness of the longitudinal side walls 53, 54 (FIGS. 7 and 9). These lateral reductions of the longitudinal side walls 53, 54 of the drawer 2 allow to readily withdraw an index card 1 such as for the purpose of writing thereon, by gripping the card at its lateral edges. The rearwardly facing shoulder 53a, 54a respectively of the step-like portions in the longitudinal side walls 53, 54 of the drawer 2 serve simultaneously as transport and support surfaces for the index cards 1 when pushing the drawer 2 into the case 4 whereby the front selector recesses 20 of the index cards 1 are protected and do not get compressed.
As shown in FIGS. 10 to 12, selector keys 7 mounted on the case 4 engage in the selector recesses 20 of the index cards 1. Each selector key is under the pressure of a counter-spring l3 and has two laterally extending shoulders 19 which limit the upward thrust of the spring 13 on the key. Below the shoulders 19 each se-.
lector key is provided with a pin 8 which is adapted to the profile of the selector recesses of the index cards 1. When the drawer 2 is closed a fillet 10 engages in a recess 11 located in a longitudinal side wall of the drawer. To displace the fillet 10 out of the recess 11, a control rail 9 is provided in the path of travel of the selector keys 7 and it is cooperatively engaged with the fillet.
At their lower ends, the pins 8 have hook-shaped portions 25 arranged so that when the key 7 is pressed down the portion 25 engages under the card stack to be retained and holds it securely in position. The bottom surface of the portions 25 are arcuate so that in downward movement they do not damage the front edges of the cards. The outer upper horizontal surface of the hook-shaped portion is formed arcuately as a journal surface.
The card index formed in accordance with the invention is used as follows: When not in use the drawer 2 of the card index is held in the case 4 by means of the latch or fillet 10 (not shown). Since the swivel stirrup 52 is resting on the guide cam 50 the index cards 1 are lifted slightly at their adjacent front faces bearing the selector recesses 20 so that these portions of the index cards come to engage the selector keys 7 from below. When actuating a selector key the pin 8 of this key is pressed on the projecting index card corresponding to the key in the cut-out zone of the selector recesses-20 of the index cards 1, and the index card 1 is bent over the raised swivel stirrup 52, together with any other index cards lying below it, so far into the recess 16 of the drawer 2 that the entrainment members 6 engage in the entrainment recesses 15 of the index cards 1. Simultaneously any other index cards that may be remaining in the case are held back by the pressed down pin 8 of the actuated selector key 7. During the last phase of the depressing operation, the drawer latch means is released. The drawer 2 travels out of the case 4 to the front whereby the selected index cards 1 are entrained by the entrainment members 6. Simultaneously the stirrup 52 is tilted from its initial upper raised position into the groove 51 and comes to rest in a position below the base of the drawer 2. After the drawer 2 has traveled out, the drawer may be readily pushed back into the case 4.
The card index formed in accordance with the invention is of a simple design and may be easily and economically manufactured. In the extended position of the drawer the index cards which have remained in the case assume a flat configuration within the case. As a result of the smaller side wall portions of the drawer individual index cards may be readily removed. Due to the fact that when pushing in the drawer the index cards are gripped along their side edges, and as the cards are pushed back together with the drawer any damaging of the selector recesses of the index cards I is avoided. In comparison to the index cards according to the above-mentioned patent the stepped arrangement of the selector recesses of the index cards according to the present invention results in the further advantage that even with a small number of index cards a positive engagement of the entrainment members 6 is assured despite a smaller travel of the selector keys.
