FR2641981A1 - Surface for spreading out and distributor of small flat objects (cards) - Google Patents

Abstract

Device for spreading out a large number of small flat objects (cards), such as playing cards, transparencies, microscope slides, etc. The invention relates to a device which rapidly spreads out a large number of cards and enables them to be gathered up rapidly. By reducing the handling operations, it limits fingerprints. It makes it possible to pick up a card easily. It consists of a surface 1 for spreading out, equipped with stops 3 and with a distributor 2 equipped with a one-by-one scraper 4 sweeping the deposited cards and preventing the simultaneous depositing of two cards. The cards are gathered up with the distributor, in the opposite direction from spreading-out, or with two fingers, rapid stacking being possible since one card always rests on a stop or on the preceding card, via one of its edges. The device according to the invention is intended particularly for spreading out and rapidly gathering up several cards.

Description

 The present invention relates to a device for spreading in large numbers - small flat objects: cards & playing, slides * microscope slides etc. In the following, for the sake of clarity, we will call "cards" of such objects.

 When one wants to examine several tens of "cards" simultaneously, one is obliged to arrange them one by one, the hand, side & chote. Then, during the pickup, it is impossible to combine initial order of "cards" and speed. In addition, these manipulations leave fingerprints sometimes harmful.

 The device according to the invention overcomes this loss of time, provides a very fast and regular distribution, limits the number of fingerprints, finally, it allows the quick pick up in the initial order. It is made of a spreading plan and a dispatcher.

 The first has protruding bumpers or stops, of rectangular or triangular section, transverse, parallel to each other and equidistant from d. This distance d is such that a "card" can not be inserted between two consecutive stops and always rests with an edge on a stop or the previous card. This allows fast pickup by stacking and facilitates the entry of a "card" <short nails>.

 For slides, microscope slides, etc., the spreading plane is in diffuser material illuminated from behind.

Dispatchers can be very varied models provided they push ahead of them on the spreading plan one or more stacks of "cards". Only the "card" of the bottom of the pile meeting a stop remains in place, the rest of the pile being pushed to meet the other butees. All distributors must have a board made of cardboard, plastic or steel. . . or a brush. who, sweeping the "cards" depo sweats, prevents the untimely spite of "cards" in excess: this is the raclette
uniqueness. It is adapted in size and nature to "cards" spread <in 2 side parts rubbing on the frame for slides>.

According to the value of d, the "cards" are overlapped or not
If they are not to overlap, the height h of the stops should be equal to the thickness e of the cards.

 If they are to overlap, the stops (which are only used to stop them) may have a lower height h.

Then, by moving in the opposite direction, the distributor reconstitutes the initial piles thanks to the squeegee of uniqueness which hangs the thickness of the "cards" exceeding stops and pushes them on the others. If h = e, the fast and orderly picking is obtained by interlacing the cards with the index and middle fingers in the opposite direction to the spreading.

The accompanying drawings illustrate the invention:
Figures 1 and 2 show in perspective, the device according to the invention.

 Figure 3 shows in perspective, a variant of this device.

 The device shown in FIG. 1 comprises a spreading plane (1) bearing stops <3) equidistant and a distributor (2) consisting of 4 vertical walls, slightly flared upwards, 2 walls being indented and their apex for the first time. easy introduction, from the top, of a stack of "cards". The walls (5) and <6) recessed at the base to let out the "cards", each carry a squeegee of uniqueness <4). In another variant, these two walls can simply be ainciated at the base, thus forming the squeegee of uniqueness.

 In another variant, the splitter <2) can also be wide enough to be easily placed around a stack of "cards" placed at the beginning of line.

The "cards" are spread out with this type of splitter by moving, in the hand, according to the arrows <7) the splitter (2) loaded with a stack of "cards", without making him turn back on
himself at the end of the line since being symmetrical, he deposits the "cards" in one set as in the other. In advance, an imperceptibly raises the front of the distributor <2) not to hang the stops <3), the rear resting constantly on the plane of spreading (1).

In the embodiment according to FIG. 3, the splitter <2> may be of the "moving bridge" type on the spreading plane (i>. It carries a squeegee of unity <4) covering all the rows of "cards". "& étaler and who, on the go does 1 'étalement, and return pickup
In a variant, the spreading plane (i> may include slides guiding the splitter <2) in its displacement and on which will rely the "cards" if the plane is straight.

Claims (7)

 1) Device for spreading and picking up cards, slides, microscope slides, characterized in that it comprises a spreading plane <1) carrying stops <3? Stopping the cards and a splitter (2> driving one or more stacks to spread.  2> Device according to claim 1 characterized in that the stops <3) are equidistant bands of d  3) Device according to claims 1 and 2 characterized in that the abutments <3) are strips of height less than or equal to the thickness of the cards.  4> Device according to one of claims 1 or 2 characterized in that a card can not be inserted between two abutments <3) consecutive.  5. Device according to any one of the preceding claims, characterized in that if the height of the stops is less than the thickness of the cards, the latter must overlap.  6) Device according to claim 1 characterized in that the splitter <2? has a single squeegee <4) which drives the unblocked cards by a stop (3>.  7> Device according to any one of the preceding claims, characterized in that, when the cards protrude in thicknesses stops <3) and partially overlap, the squeegee of <4> uniqueness reformes the initial piles, if the dispatcher has moved in the opposite direction of the direction of spreading.
