Convenience to use.

Description

The utility model relates to computing hand-held devices, in particular, to accounts, and can be used in preschool institutions and elementary grades to assist in learning.

Known abacus soroban containing a rectangular frame with multiple rods installed in its opposite rods, each of which has 5 beads strung, the upper row of which is separated from the lower rows by a dividing rod located in the frame opening, on which at least three expressive marks are made . The abacus is reinforced with a crossbar, has two supports, a shoulder strap is attached to the frame [UA 105309 U, G06C 1/00, 2016].

Such accounts are intended primarily for demonstration and training of a group of people, but not for individual use. In addition, they have some difficulties in manufacturing, which increases their price. In addition, all beads have the same color, which does not contribute to a better assimilation of the account.

Closest to the claimed utility model are pocket scores, which contain a rectangular frame with knitting needles inserted in its opposite long sides, each of which is strung with five bones. The upper row is separated from the four lower rows by a dividing rod, the spokes being longer than the size between the opposite long sides of the frame and inserted into the holes made from the inside of the long sides with tension. The bones are colored and each row of seeds has a different color [UA and 2016 08263, G06C 1/00, 2016].

These accounts take into account the shortcomings of the previous analogue, however, the inconvenience of its use is that each time you need to return the bones with your fingers to their original position.

The utility model is based on the task of improving pocket accounts by adding a mechanism that, after performing arithmetic operations, would automatically return the bones to their original position for ease of use of accounts.

The problem is solved by the fact that pocket scores containing a rectangular frame with spokes inserted into its opposite long sides, each of which is strung with five seeds, the upper row of which is separated from the four lower rows by a dividing rod, according to the utility model, have a mechanism for automatic seed return in the initial position after counting, containing a horizontal rod placed parallel to the dividing rod and connected in the middle with a perpendicular rod having at the end knees interconnected by fixing hinges, and the last knee is connected to a control button located on the upper part of the frame, while the knees are decomposable by pressing a button to lower the horizontal bar and return the bones to their original position after the end of counting.

The presence in the pocket accounts of a mechanism for automatically returning seeds to their original position after performing arithmetic operations creates convenience when using them.

The invention is illustrated by illustrations.

In FIG. 1 shows pocket scores, front view;

in FIG. 2 - pocket scores, front view under the action of the mechanism of automatic return of seeds to their original position after counting;

in FIG. 3 - pocket scores, rear view;

in FIG. 4 - pocket scores, rear view under the action of the mechanism of automatic return of seeds to the initial position after counting.

Pocket abacus contains a rectangular frame 1 with spokes 2 inserted into its opposite long sides. Five spikes 3 are strung on each spoke 2, the upper row of which is separated from the four lower rows by a dividing rod 4.

Pocket accounts have a mechanism for automatically returning seeds to their original position after counting, containing a horizontal rod 5, parallel to the dividing rod 4 and connected in the middle with a perpendicular rod (not visible), which is connected at the end of the knee 6 by fixing hinges 7. Last knee 6 connected to the control button 8 located on the upper part of the frame 1. The knee 6 is made with the possibility of decomposition by pressing the button 8 to lower the horizontal rod 5 and return the bone points 3 in the initial position after the end of the account.

Pocket abacus operates as follows.

After arithmetic, when the bones 3 are in a different position, press the button 8, after which the knees 6 of the automatic pitting 3 mechanism are expanded, the horizontal rod 5 is lowered and the bones 3 are returned to their original position.

Claims (1)

Pocket scores containing a rectangular frame with knitting needles inserted into its opposite long sides, each of which is strung with five seeds, the top row of which is separated from the four lower rows by a dividing rod, characterized in that they have a mechanism for automatically returning the seeds to their original position after counting, comprising a horizontal rod placed parallel to the dividing rod and connected in the middle with a perpendicular rod having, at the end of the knee, fixed to each other ruyuschimi joints, the knee and the latter is connected to a control button disposed at the upper portion of the frame, wherein the knee configured to decomposition by pressing a button for lowering the horizontal bar and the return to the original seed position after closure account.
