Abstract

The pocket of the pocket contains a rectangular frame with spokes inserted into its opposite longitudinal sides, each of which is strung five bones, the upper row of which is separated from the four lower rows by a dividing rod. It has a mechanism for automatically returning the bone to its original position after counting, which contains a horizontal rod, located parallel to the dividing rod and connected in the middle with a perpendicular rod having at the end of the knee, interconnected by fixing hinges, and the last knee is connected with control button located on the upper part of the frame, with the knees made with the possibility of folding when you press the button to lower the horizontal rod and return the bones to their original position after finishing calculation.

Description

The useful model belongs to hand-held computing devices, particularly calculators, and can be used in preschools and elementary schools to aid in learning.

A soroban abacus is known, which contains a rectangular frame with a set of rods inserted into its opposite rods, on each of which 5 beads are strung, the upper row of which is separated from the lower rows by a dividing rod located in the armhole of the frame, on which at least three expressive marks are made. The counter is reinforced with a bolt, has two supports, a shoulder strap is attached to the frame (СА 105309 |, 506С 1/00, 20161.

Such a calculator is mainly intended for demonstration and training of a group of people, and not for individual use. In addition, it has some complications in manufacturing, which increases its price. In addition, all beads have the same color, which does not contribute to better learning of counting.

The nearest to the useful model claimed is the pocket abacus, which contains a rectangular frame with spokes inserted into its opposite longer sides, on each of which are strung five bones, the upper row of which is separated from the four lower rows by a dividing rod, the spokes having the length is greater than the size between the opposite longer sides of the frame, and are inserted into the holes made on the inner side of the longer sides with tension, and the bones are colored and each row of bones has a different color (ША и 2016 08263, 506С 1/00, 20161.

This abacus takes into account the shortcomings of the previous analogue, but the inconvenience of using it is that every time you need to return the bones to their original position with your fingers.

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

The problem is solved by the fact that the pocket calculator, which contains a rectangular frame with spokes inserted into its opposite longer sides, on each of which five bones are strung, the upper row of which is separated from the four lower rows by a dividing rod, according to a useful model, has a mechanism for automatically returning the dice to their original position after counting, which includes a horizontal rod, placed parallel to the dividing rod and connected in the middle to a perpendicular rod, having at the end knees, connected

Between themselves with locking hinges, and the last knee is connected to the control button located on the upper part of the frame, while the knees are made with the possibility of unfolding when the button is pressed to lower the horizontal rod and return the bones to their original position after the end of counting.

Implementation of the mechanism of automatic return of dice to the original position in the pocket calculator after performing arithmetic operations creates convenience when using it.

A useful model is explained with drawings.

In Fig. 1 shows a pocket calculator, front view; in Fig. 2 - a pocket abacus, front view, with the action of the mechanism of automatic return of dice to their original position after counting; in Fig. C - pocket calculator, rear view; in Fig. 4 - cat counting machine, rear view, with the action of the mechanism of automatic return of the bones to their original position after counting;

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

The pocket calculator has a mechanism for automatically returning the bones to their original position after counting, which contains a horizontal rod 5, placed parallel to the dividing rod 4 and connected in the middle to a perpendicular rod (not visible), which has at the end knees 6, connected to each other by locking hinges 7. The last knee 6 is connected to the control button 8, located on the upper part of the frame 1. The knees 6 are made with the possibility of unfolding when the button 8 is pressed to lower the horizontal rod 5 and return the bones C to their original position after the end of counting.

The pocket calculator functions as follows.

After performing arithmetic operations, when the dice Z are in different positions, press the button 8, after which the knees b of the automatic return mechanism of the dice Z unfold, the horizontal rod 5 lowers and returns the dice Z to the original position.
