Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides a drawer for accommodating index cards that is pretensioned by a spring in the open position and has a sorting perforation, and a drawer for storing index cards that remains in the case. a key lever having a pressing piece that engages with the sorting hole;
A drawing piece on the drawer bottom plate configured as a protrusion inclined on the front edge with respect to the opening direction, an engaging piece for the drawing piece provided on all index cards, and a drawer latch that can be released by a key lever. Concerning an indexed ledger with.

[Prior Art] In a known index-type ledger of this type, a guide piece is provided in the center of the bottom plate, and this piece projects into a corresponding engagement hole. This single entrainment piece is not particularly high in height and has a relatively flat slope. By pressing a key, the pressure piece is moved from below into the sorting hole and holds the index card that is to remain in the case. Other index cards that are not retained are carried out with the drawer by a single carrying piece. In this case, it often happens that individual cards, which should normally be taken out together with the drawer, become stuck due to friction between the cards or due to warpage. In such a case, the card cannot be removed at all or only a portion of the card can be removed, resulting in a wrong selection. A wrong order or arrangement of the cards will inevitably result in a missort (see German Patent Application No. 2741222).

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an indexed ledger of the type mentioned at the beginning which reliably prevents erroneous sorting.

[Means for solving problems]

This problem is solved by the fact that the pressing piece is disposed in front of the driving piece, close to it, or between the driving pieces, and cooperates with the driving piece when viewed in the opening direction of the drawer. Basically, the index cards are tilted so as to be thrown away from the bottom plate, and by providing sorting holes in all the pressing pieces except for the pressing pieces where the index cards are arranged corresponding to the index numbers, resolved.

〔effect〕

According to the invention, the entraining piece and the pressing piece cooperate in a very special manner. When the pressure piece corresponding to a particular index card is pressed down by pressing the key, the pressure piece abuts the card in the area of the sorting hole. This is because the card lacks screening perforations in certain locations. This pressure piece prevents the index card and the card below it from sliding over the slope of the entrainment piece. In other words, a suitably selected index card is thus reliably prevented from being carried away over the slope of the carrying piece, while the card above it can be removed without any hindrance.

〔Example〕

Various embodiments are possible within the scope of the invention.

In one embodiment, the drawer is provided with an auxiliary entrainment piece that supplements the aforementioned entrainment piece, the latter being already selected and entrained by the first-mentioned entrainment piece when the drawer is pulled out by a certain distance in the opening direction. You will work to completely remove the card from the case.

Various advantageous structural designs are possible with this embodiment.

In another embodiment, a notepad index book according to the present invention is configured as follows. That is, the entraining piece is pivotably supported on the drawer and can be rotated in such a way that, when the drawer is pulled out a certain distance, the inclined part is in an approximately vertical position, during which the entraining piece covers the area of action of the pressure piece. It is long enough to make a turn before leaving.

In this embodiment, the entraining piece itself is used to reliably and completely remove the index card carried by it from the case after it has left the area of action of the pressure piece by pivoting.

The third embodiment combines some features of both embodiments described above. On the one hand, the tilting guide of the drawer is designed immovably. Instead, an auxiliary entrainment piece is movable or pivotable, and an auxiliary engagement hole corresponding to the auxiliary entrainment piece is provided in the index card. After the drawer has been pulled out by a short distance in the opening direction, the auxiliary entrainment piece, which does not provide any displacement, engages reliably with the selected index card. The movement of this auxiliary entrainment piece can be guided very precisely by means of suitable guiding edges or the like. In order to securely hold and transport the selected index cards, a slight assistance is provided by the protruding holddown of the rotatable auxiliary guide piece.

In one embodiment of the invention, the pressing piece and the auxiliary entraining piece are arranged symmetrically between the side walls of the drawer, so that a package of index cards can be used, and the back For example, it may be provided with ruled lines extending from the front to the rear. In conjunction with a suitable key mark strip, the notepad can thus also be used in landscape orientation and is therefore also suitable as a coaster for a phone that is wider than it is deep.

The perforations for sorting and the holes for engagement with the entrainment piece, which are sensitive to wear and tear, are not provided on the edge of the index card and are therefore not visible to the user. The ability of the indexing ledger according to the invention to withstand relatively large deviations in the given stiffness and flatness of the cardboard of the indexing cards is considered a significant advantage over known ledgers. I can do it. It is particularly important to emphasize that even if the index cards are not placed in a particular arrangement or order in the drawer, the possibility of missorting is eliminated.

Further advantages and details of the invention will be explained in more detail below on the basis of various exemplary embodiments and with reference to the drawings.

In a preferred embodiment according to the invention, the indexable ledger consists of a case 1 which is open towards the rear wall of the case and in which a drawer 5 guided under tension by a spring 38 is guided. The drawer 5 has a raised part 8 extending over the entire width of the drawer at its front part, and a slot-shaped recess or a recessed part opening toward the rear wall of the case at its rear part, which is lower than the front raised part 8. Vertical groove 9,
and entrainment pieces 11 aligned in the longitudinal direction of the drawer 5
and an auxiliary entrainment piece 10.

The case bottom plate 3 has a vertical groove 9 when the drawer 5 is closed.
A support 12 is mounted to engage the. The support 12 has a support surface 13 located higher than the top surface of the auxiliary entrainment piece 10.

The auxiliary entrainment piece 10 is preferably attached to each edge of all or part of the longitudinal groove 9 and extends at a small distance from the support 12 and parallel thereto. Auxiliary entrainment piece 1
The front edge of 0 is located slightly behind the stop surface 41 of the support 12 and its top surface is below the plane of the support surface 13. A driving piece 11 is formed on the bottom plate 6 of the drawer 5 in a position parallel to the support 12 and the auxiliary driving piece 10 and offset to the front.

Due to the arrangement of the front elevation 8 of the drawer 5 and the support 12 with the support surface 13, the index card 7 lies hollow in the area between the support 12 and the front elevation 8. The index card can thus be bent downwards by the pressing piece 21 and gripped by the entraining piece 11.

On the index card 7, which has a perforation 25 for sorting and an engagement hole 26 for the carrying piece (the arrangement of which will be explained in detail below), it consists of two two-armed levers 17, 18 elastically connected in the front and rear; two axes 14,1
A number of key levers 16 are arranged in the case 1, and the free ends of the key levers each have a key 20 and a key nose end 43 on one side, and a pressing piece 21 and a locking nose end on the other hand. end 22 and guide fork 24. The key lever 16, consisting of two two-armed levers 17, 18 which are elastically connected in front and behind each other, may be integrally molded from a suitable spring-elastic material. However, there are two separate two-armed levers, one end of which forms the key 20 and the key nose 43, and the other end of which forms the pressing piece 21, the locking nose 22 and the guide fork 24. It is also possible, and in some cases possible, to connect the two two-armed levers at their respective free ends by a sufficiently elastic coupling member 19 made of metal, for example. is even advantageous. To manufacture a single double lever, relatively expensive materials have to be used if this lever is to withstand permanent loads, possibly using separate joint parts, such as spring steel. This can be a cost saving.

The card holder 23 of the case lid 2 holds the index card 7
At the same time, the pressing piece 21 is guided by the guide fork 24 of the key lever 16.

The drawer 5 is hermetically held by a latch 32 extending parallel to the front edge of the case 1;
2 is a notch 40 formed in the side wall 30 of the drawer 5;
The compression spring 31 forces the spring 31 into elastic engagement. A ramp 28 is disposed in the travel path of each key nose 43 for pulling the latch 32, the lower end of which is configured as a splint 29 for limiting the key travel.

The index card 7 is provided with two parallel rows of elongated sorting holes 25 and elongated engaging holes 26 for engaging pieces. The number of sorting holes 25 of each index card 7 below the pressing piece 21 is one less than the number of pressing pieces 21, and in the row of sorting holes of each index card 7, there is a sorting hole corresponding to an index number or an index letter. Perforations are missing. On the other hand, the number of elongated entrainment strip engaging holes 26 is the same in every index card and is equal to the number of entrainment strips 11.

When using the memo paper index, when the key 20 corresponding to the character or symbol is pressed, the vertical movement of the key 20 causes the two-arm lever 17 to pivot, the elastic coupling part 19 moves upward, and the rear two-arm lever 18 pivots around axis 15 correspondingly. The bearing of the rear lever 18 on the shaft 15 is configured as a slot in case of positional movements. When the key is pressed in this manner, the guide fork 24 at the end of the key lever 16 is guided by the card holder 23 and descends, and the corresponding pressing piece 21 engages and locks with the sorting hole 25. When an index card to be selected, that is to say an index card which does not have a sorting perforation in its place, is encountered, this card and possibly the group of cards below it are pressed by means of the entrainment piece 11. Due to the elastic deformation of the joint member, the movement progresses further, during which time the drawer 5 is unlocked, and the drawer is pushed by the spring 38 and begins to move forward. The sorting index card 7 that has been pushed into the action range of the pulling piece 11 may be pulled out by the pulling piece 11 while leaving the index card in the device, and the remaining index card 7 is pulled out by the pressing piece 21. It is locked by.

The entraining piece 11 preferably has a truncated pyramid shape with rounded corners. Even if the index card 7 that is not pressed down by the operation of the pressing piece 21 becomes sagging and enters the action range of the entraining piece 11 below, it will still slide off the entraining piece 11 because the inclination of the effective slope is selected to be large. . However, the selected index cards 7 are prevented from slipping down by the pressing piece 21, and are therefore forcibly carried away by the entraining piece 11 within the action range of the pressing piece 21. If the selected index card 7 and possibly the group of cards below it are pulled down by the support surface 13, these cards are stressed by the pressure piece 21, so that the edge of the card is bent into the bottom part of the bottom plate 6 of the drawer 5. The entraining piece 11 is the pressing piece 2
When the card leaves the area of effect of
can be grasped by the drawer 5 and sent out together with the drawer 5. The auxiliary entrainment piece 10 is cut out at the rear, as is clearly visible in the drawing, in order to ensure that the card is entrained and held by it. The index card 7 locked by the pressure piece 21 need only be shifted forward by the distance resulting from the gap between the rear edge of the sorting hole 25 and the locking edge of the pressure piece 21. Since the distance 〓 is made shorter than the length of the support surface 13, the locked index card 7 does not slip off the support 12, and thus the card is reliably held outside the action range of the auxiliary guide piece 10 running. be done. The spacing between the auxiliary entrainment piece 10 and the supports 12 is selected to be small enough that the remaining cards do not become trapped even if they sag between the support surfaces 13 of the individual supports 12.
For the same purpose, the support surface 13 of the support 12 is located slightly higher than the top surface of the auxiliary entrainment piece 10 adjacent to the support.

A major advantage of the index type ledger of the present invention compared to the known index type ledger is that there is no specification of the arrangement or order when storing the index cards 7 in the drawer 5, and in terms of rigidity and hardness, the index type ledger of the present invention has a great advantage. Cardboard for index cards can be used, which provides a much wider range of options than for ledgers. In this connection, it must also be taken into account that cardboard is a "living" material and can easily warp, for example due to changes in air humidity, which can lead to disturbances in known devices.

When sending out the drawer, the user presses the key 20.
Even if you take your finger off too soon, the pressing piece 21
The locking nose end 22 formed in the screening hole 25
By grasping under the trailing edge of the case, cards remaining in the case can be prevented from becoming unlatched.

As a result of the pre-elastic tensioning of the connection part 19, the key neck part 33 and the pressure piece 21 with the guide fork 24 are each again brought into contact with the housing lid part.

In a preferred embodiment, a container 36 for memo paper, etc. and a groove 3 with a writing instrument are formed under a part of the raised part 8 and are closed with a flip-up lid 35 supported at the rear.
4 are provided if all index cards 7 remain in the case. Therefore, the pressing piece 21 of the key lever 16 grasps all the index cards 7. A boat-shaped grip 37 connecting the groove 34 of the container 36 allows easy access to notepads and writing instruments.

Storing the drawer 5 after sorting is performed in the following steps. The index card 7 remaining in the case 1 is pushed back until its rear edge abuts against the stop surface 41 of the support 12. As a result, the locking nose end 22 of the last used key lever 16 is released, and the key lever brings its neck 33 and pressing piece 21 into contact with the case lid 2 again. The selected index card 7, possibly together with the group of cards below it, is placed on the bottom plate 6 of the drawer at the rear once the drawer 5 has been fed out.
It's on. Index card 7 when pushing
The trailing edge is pushed up onto the support surface 13 by an inclined guide 42 formed on the support 12 and released from cooperation with the entraining piece 11 and the auxiliary entraining piece 10. At the same time, the spring 38 is tensioned and the compression spring 31 forces the latch 32 into the recess 40, thus closing the drawer 5.

The notepad index is now ready for the next sorting.

In the embodiments shown in FIGS. 7 to 9, identical parts are given the same reference numerals. This embodiment is primarily distinguished by the lack of an auxiliary entrainment piece 10 in the rear region of the drawer. Furthermore, no sinking portion is provided in the rear region of the drawer 5. The bottom 6 of the drawer 5 is completely flat. The entraining piece 11a is rotatably supported by a pin 45. Each entrainment piece 11a is provided with a rotating snout 46 which lies within the slit 44 in the closed position (FIG. 7). The slit 44 is the entrainment piece 1
The length is such that the rotating nose end 46 comes into contact with the slit end before the pressing piece 1a leaves the action range of the pressing piece 21. In the state shown in FIG. 8, this position has not yet been completely achieved. In FIG. 9, the entraining piece 11a has already pivoted to such an extent that the slope now assumes a vertical position and is ready to reliably entrain the sorting index card after leaving the area of action of the pressure piece 21. ing. After performing the pivoting movement, the key can be released.

In the embodiments shown in FIGS. 7 to 9, the pressing piece 2
1 is also moved downwards until it abuts the index card 7 in question, i.e. an index card 7 which does not have a screening perforation in its place. If the drawer 5 is then moved forward, this index card 7 and the cards below it are prevented from sliding down the slope of the entrainment piece 11a. The index card 7 thereon is removed by the pressing piece 21 (see FIG. 8). If this removal has taken place, a pivoting movement takes place and the entraining piece 11a
The perforation of the index card 7 is ensured by the vertical front edge of the index card 7.

Another embodiment shown in FIGS. 10 to 13 is
Essentially, it shows a combination of the two embodiments described above. Here again, the same parts are given the same reference numerals. Drawer 5 in the embodiments of Figures 1 to 6
The auxiliary entrainment piece 10 provided at the rear end is omitted here. Furthermore, the sink is also missing and the bottom plate 6 of the drawer is very flat as in the embodiment of FIGS. 7 to 9.

The entraining piece 11 is designed to be longer in the direction of movement of the drawer, and one or more further auxiliary entraining pieces 10a are movably arranged on the drawer 5 and the bottom plate 6 between the cams. The index card 7 is provided with an auxiliary engagement hole 50, the front edge 55 of which is offset rearward from the front edge of the entrainment piece engagement hole 26 (see FIG. 11).

In this embodiment, the auxiliary entrainment pieces 10a are each formed at one end of a bell crank 51, which is supported under the bottom plate 6 so as to be pivotable about an axis 52. The other free end of the bellcrank has a nose end 53 that cooperates with a guide edge 54 formed on the bottom plate 6.
have.

In the closed position (FIG. 10), the auxiliary entrainment piece 10a is held in position at the rear by one of the guide edges 54. In this case, the vertical conveying edge and presser foot 56 of the auxiliary entrainment piece 10a are spaced a certain distance from the front edge of the auxiliary engagement hole 50, and are locked during operation and carried by the entrainment piece 11. Index card presser foot 56
It is made so that it cannot be grasped by anyone.

As soon as the front edge of the auxiliary engagement hole 50 of the locked index card 7 is located behind the presser foot 56 (see FIG. 12), the auxiliary entrainment piece 10a is guided by the guide edge 54 and It turns until it reaches the front edge of the engagement hole 50. The presser foot 56 grips the selected index card 7 and prevents it from slipping off (see FIG. 13).

The process described above for ensuring entrainment is completed before the entrainment piece 11 leaves the area of action of the pressure piece 21.

Since the front edge of the engagement hole 26 for the entrainment piece and the front edge of the auxiliary engagement hole 50 of the index card 7 are shifted in advance, the tip of the presser foot 56 is aligned with the slope of the entrainment piece 11 in its front position. Located slightly further back. In this way, the index card 7 taken out from the drawer 5 can be stored again without the risk of its trailing edge getting caught on the auxiliary guide piece 10a. That is, the cards are carried on the entrainment piece.

When the drawer 5 is completely pushed in, the auxiliary guide piece 10a
The index card 7 swings back to its normal position again, and the index card 7 enters the action range of the entraining piece 11 and the auxiliary entraining piece 10a, and is ready for the next selection.
