Description

DETAILED DESCRIPTION OF THE INVENTION The invention includes a housing having a cover and a bottom with a plurality of selection keys and an extractor under the action of a compression spring and closeable by a locking device, the housing having a cover and a bottom. A stack of a plurality of recording cards stored in a storage device is provided with a selection tongue having a hole formed in its rear edge, the selection tongue having a hole therein, and a selection tongue having a hole therein. the size of the selection tongue increasing stepwise from one side to the other with one hole, each selection key fixed to a swinging arm configured as a lever with a card deterrent at its free end; and the card restraining device of the rocking lever is arranged in a row, and when the selection key is pressed, all the recording cards above the recording card associated with this selection key are When pulling out the extraction, the card restraining device is inserted from below into the hole of the selection tongue of the recording card, and at the same time the selected recording card and all the recording cards below it are pulled out together with the extraction. for unlocking the extractor with an interlocking cam for cooperating with the recording card and for engaging an interlocking hole in the recording card and pushing out the unlocked extractor by means of a compression spring. The present invention relates to a data recorder with a recording card selection device, which includes a device actuatable by a rocking lever of a selection key for releasing a recording card selected by the selection key.

Various embodiments of data recorders with selection devices are known. These include a housing for receiving a stack of loose recording cards;
and a keyboard having correspondingly numbered keys whose actuation selects the desired card. Any data or notes may be written on the record card in alphabetical order for later reference. Known embodiments of data recorders are configured relatively flat in the closed position;
In order to open the data recorder at a desired location and freely view the data on the card, it can be opened by a plurality of manually actuated keys. The data recorder configured in this manner further comprises: whereby a cover covering the recording card can be moved to a closed position, and upon closing the cover, the lifted recording card can be automatically returned to its initial position; Equipped with a close key.

Furthermore, the extractor which is under the action of the thrust spring and is closed by a lock, and the extractor whose record card is selected by means of a key adjusted to unlock the extractor, is extracted by the thrust spring. Data recorders are also known which consist of a housing with a device for twisting and releasing the housing.

Furthermore, the selection keys of the rocking lever are composed of plate-like square or rectangular parts fixed to the ends thereof, and the selection keys arranged in a row one after the other are three selection keys each. The selection key, which has a width matching the width of the swinging lever having a width corresponding to the width of the swinging lever and which faces the card restraining pin at the rear end of the swinging lever, overhangs the two swinging levers adjacent to the right side. The front selection key overhangs two swing levers adjacent to the left side, and the center selection key extends left and right onto the swing levers adjacent to both sides of this selection key. The card restraining pins of each rocking lever are connected to the rocking levers, and a card restraining pin of each rocking lever is formed at the end thereof and faces vertically upward, and when the rocking lever is actuated, the card restraining pin is connected to the recording card hole or the like from below when the rocking lever is actuated. consisting of a generally U-shaped portion formed in the end of the swinging lever having a foot extending to a selection key with a rod engaging the notch;
The extractor consists of a plate-shaped extractor bottom with a front end member that seals the extractor movement opening in the front wall of the housing when the extractor is in the insertion position, and is formed open at the rear and sides and has a rear edge. It has a number of slot-like notches corresponding to the number of card restraining pins having a length corresponding to the length of the U-shaped portion at the end of the swing lever in the region, and the extraction limiting walls on both sides are plate-like. Consisting of two limiting walls disposed on both sides of the extractor bottom and formed on the inner wall surface of the housing cover, each swing lever has a card restraining pin at the end of the housing to guide the swing lever. A device for unlocking the extraction consists of a U-shaped shackle connected to the cover of the housing, with a vertically extending slot-like hole in which a cam formed in the inner wall of the cover is engaged and guided, and a device for unlocking the extraction. A web extending transversely to the longitudinal direction of the swinging lever is disposed at the top of the swinging lever so that it can be actuated, and the leg of each shaft is When the shackle is lifted by operating the key, the locking cam cooperates with a counter cam formed in the extractor so that the extractor moves outward so that the lock cam is released from the countercam. Data recorders are also known.

The locking and unlocking of extraction is thus effected by means of a U-shaped oscillating shaft whose leg is pivotally supported at the inner end of the data recorder housing, and when the selection key is actuated, the oscillating shaft connected thereto is activated. The web of the shackle connected to the legs abuts against the portion formed at the rear end of the swinging lever such that the swinging lever lifts the shackle with its rear end, and extraction is selected by unlocking. Data recorders are also known in which a locking cam formed in the leg of the shank is moved out of the path of movement of a stopper cam formed in the extractor so that it can be moved out together with the recording card by the action of a compression spring. It is.

The use of a shackle for locking and unlocking the extraction is disadvantageous insofar as the size of the housing must be maintained so that the shackle can be freely swung inside the housing. This results in that no minimum size can be chosen for the housing. Furthermore, it follows that sufficient space must be provided on the sides of the extractor to receive the shaft legs.

The object of the present invention is therefore to provide a data recorder with an extractor lock and an unlocking device that is economical in terms of production and to improve the data recorder housing in such a way that it increases its functionality and at the same time retains its minimum dimensions. It's about doing.

In order to solve this problem, according to the present invention,
The extraction lock release device is constituted by a rocking plate that can swing around a horizontal rocking axis in the rear region of the housing, and a stopper edge that can be abutted by the rocking plate by the rear end of the rocking lever. and on the side edges extending transversely to this, each has one extraction-oriented locking cam, the locking cams extending obliquely to the housing bottom towards the rear housing area. an engagement recess or a stopper cam having a rear sliding edge configured in the end region of the bottom of the extractor, and a locking cam being released from the engagement recess when the stopper edge is lifted by rocking of the rocking plate; As is possible,
A data recorder of the type mentioned at the outset is proposed, which is characterized in that it cooperates.

By using a rocking plate arranged in the rear region of the data recorder housing for locking and unlocking the extraction, the rocker plate is located in the rear region of the housing and in the lateral region of the housing. Since it takes up less space, it allows the data recorder to take minimum dimensions, so that the extractor can have almost the entire width of the housing, so that a relatively large writing surface is provided on each individual record card. It has the advantage that the recording cards can likewise be chosen from a wide range.
In contrast, the sufficient width of the extractor and the corresponding dimensions of the recording card provide a large writing surface on the recording card, so that the extractor does not require a very large length, and long selected extractors can be used for data recording. It is considered a drawback if operating the selection key causes the relatively long selected extraction to move out, since there is often not enough space for the extraction from the vessel. Furthermore, the use of a rocker plate as the extractor unlocking device offers the advantage of economical manufacture. The rocker plate is constructed in one piece, and the rocker bearings necessary for its use can be formed at the same time during the manufacture of the housing bottom. Furthermore, since the swinging lever is free together with the holding pin and the shackle that gets in the way when assembling the data recorder is retracted, assembly of the data recorder with such a swing plate is simplified. Furthermore, the data recorder has a relatively small height, since there is no longer a need for space inside the housing into which the U-shaped shackle used in otherwise known data recorders can swing. obtain.

Further advantageous embodiments emerge from the claims.

The features of the invention are illustrated in the drawings by way of example.

The data recorder shown in FIGS. 1 to 5 consists of a housing 10 having a box-shaped cover 11 and a box-shaped bottom 21. The data recorder shown in FIGS. cover 1
1 and the bottom part 21 are interconnected by a screw connection or an adhesive connection or a clip connection and are preferably made of plastic.

7, 48, 49, 50 and 51 have the same number of slot-like openings 17 as the selection keys.
The remaining portion 16c of the upper cover plate 16 may be provided with a non-slip membrane and may be sized to serve as a support for the telephone.

The bottom part 21 with side walls 23 and 25, front wall 22 and rear wall 24 has a bottom plate 26 and a slot-like opening 20 serving to receive the extractor 30 in the front wall 22.

The bottom part 21 of the housing 10 is a plate-shaped extraction bottom part 3.
1, and a front closing member 32 that seals the extractor movement opening 20 in the front wall 22 of the bottom portion 21 when the extractor 30 is inserted. The extraction bottom 31 has an interlocking cam 33 at the center of its upper surface. (See FIG. 13) The side wall of the extractor 30 is constituted by two limiting walls, only one of which is shown in FIG. 12 and is designated by the reference numeral 19. The limiting wall is formed inside the housing cover 11. It is also possible to provide the limiting wall in the housing bottom 21.

In order to draw out the extractor 30, a steel spring rod 29 is connected at one free end to the plate-shaped extractor bottom 31 and fixed at the other end to the bottom plate 26 of the bottom 21. It is arranged on the bottom plate 26 of the bottom part 21 (see FIG. 13).
The action of the steel spring rod is such that when the extractor 30 is unlocked it is pulled out by the steel spring rod 29 which tends to return to its initial position.
This corresponds to the action of a slide spring, which is tensioned when inserted into 1.

In the area of the opening 17 of the upper cover plate of the cover 11 of the housing 10, a plurality of selection keys 40 to 51 are arranged, which are formed from vertical plate-like members. In the embodiment shown in FIGS. 1 and 2, for example, the first selection key 40 represents the letters "A, B" and the last selection key represents the characters "W, Z".
Twelve selection keys 40 to 51 are provided with corresponding letters of the alphabet so as to provide the following information. These twelve selection keys 40 to 51 are arranged in a row and spaced from each other at regular intervals, so that complete operation of each selection key is possible. Other embodiments of selection keys are also possible.

The selection keys 40 to 51 have lever-like swing arms 60, 61, 62, the number of which corresponds to the number of selection keys.
63, 64, 65, 66, 67, 68, 69, 7
0 and 71, and the ends 60a, 61a, 62a, 63a, 64a, 6 of the swing lever
5a, 66a, 67a, 68a, 69a, 70a
The selection keys 40 to 51 are fixed to the swing levers 60 to 71a, and the other ends of the swing levers 60 to 71 are designated by reference numeral 60b.

(See Figure 6).

The swing levers 60 to 71 are configured as two-arm levers, and the swing levers 60 to 71 are configured as two-arm levers.
A rocker is supported on the side walls 13 and 15 or 19 of the cover 11 so that the rocker shaft 80 has a through bore extending transversely to its longitudinal axis approximately in the center, and the rocker shaft 80 passes through the through bore. Since it is pivotally supported by the swing shaft 80, the swing lever 60
71 are arranged to be freely swingable about the swing shaft 80. However, the swing lever 6
0 to 71 can also be supported on the swing shaft in other ways. For example, the swing levers 60 to 71 can have semicircular recesses that serve as bearings for the swing shaft 80. In such an embodiment of the swing levers 60 to 71, lifting of the swing levers 60 to 71 from the swing shaft 80 is prevented so that the swing levers are prevented from rising from the swing shaft 80. Suitable protrusions are formed on the inside of the cover 11 which prevent but at the same time do not interfere with the swinging movement of the swinging levers 60-71. The selection keys 40 to 51 and the swing levers 60 to 71 are preferably constructed in one piece.

Each swing lever 60 to 71 has an end 60
A card deterrent device 130 is provided between b and 71b (see FIGS. 13 and 14). Since each card deterrent device 130 is similarly constructed, one card deterrent device of the swing levers 60-71 will be described in more detail below.

The card deterrent device 130 is constituted by a U-shaped part 140, one leg 141 of which extends parallel to the swing lever 60. The swing lever 60
A web connecting the legs 141 is designated by the reference numeral 145. The U-shaped portion 140 is formed on the swing lever 60 such that its legs 141 extend in the direction of the selection keys 40 to 51.

The free end of the leg 141 of the U-shaped portion 140 is followed by a vertically upwardly directed portion 142;
The portion 142 has a wall 1 facing its web 145.
42a has a projection 143 in the upper region, which is substantially parallel to the leg 141 of the U-shaped part 140 and slightly raised in the direction of the housing cover 11, as is clear from FIG. ing. The protrusion 143 tapers into a wedge shape and transitions into an outer surface 144 facing the selection key.
This outer surface 144 makes it easy for the bending part 142 with the protrusion 143 to easily engage in the hole at the rear end of the recording card when the rocking lever with the card deterrent device 130 swings. However, this will be explained in detail later.

The web 145 of the U-shaped portion 140 of each card deterrent 130 has one generally horizontally extending rear operating arm 146 (see FIGS. 13 and 14).

The card deterrent device 130 located at the rear end portions 60b to 71b of each of the swing levers 60 to 71 is integrally connected to the swing lever.

The vertical portion 142 with the protrusion 143 of each card deterrent device 130 constitutes the device for actually deterring the card. The arrangement and configuration of the card deterrent device 130 on the ends 60b to 71b of the swing levers is such that when one swing lever is operated by pressing down the corresponding selection key, the rear end of the swing lever is lifted. At the same time, part 1 of the swing lever
42 is raised and adapted to engage a hole or notch in the trailing edge of a recording card of a stack of recording cards disposed within extractor 30, as described in more detail below.

On the bottom plate of the bottom part 21 is a U of the card deterrent device 130.
A recess 27 is provided in the area of each contact surface of the glyph 140 (see FIG. 13). The depth of this recess 27 is equal to the depth of the U-shaped portion 140 of the card deterrent device 130.
Although the depth of the recess 27 substantially corresponds to the height of the leg 141 of the recess 27, the depth of the recess 27 may be deeper. As shown in FIG. 13, the configuration of the recess 27 and the pivot axis 8 are such that the pivot lever in the inoperative position is slightly inclined relative to the rear housing area.
The relationship of 0 is important. In this inoperative position, the legs 141 of the U-shaped portion 140 of the card deterrent device 130 are supported on the bottom surface of the recess 27.
This configuration ensures complete engagement of the vertical portion 142 of the card deterrent device 130 into the hole in the trailing edge region of the card of the stack of recording cards.

The protrusion 143 formed in the portion 142 has a slight length and is arranged at the trailing edge of the recording card to ensure the insertion of the card deterrent device 130 into the hole of the recording card and the inhibition of unselected cards. It is chosen to be no larger than the holes provided in the area. This rearwardly bent protrusion 143 of the card deterrent device 130 is located under the selected card when the extractor 30 is withdrawn and prevents the recording card being withdrawn with the extractor 30 from floating up. This configuration of the card deterrent device 130 also provides this advantage in the case of recording cards that are no longer flat after long-term use.

An unlocking device 300 consisting of a rocking plate 150 is provided so that the extractor 30 can be withdrawn after actuation of the selection key (see FIGS. 6 and 8). A rocking plate 15 is arranged to be rockable around a horizontal rocking shaft 153 in the rear region of the housing 10.
