Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a convergence device for preventing dispersion of counting sticks used mainly for children's arithmetic learning.

(Prior Art) Conventionally, in order to help children in lower grades understand the composition and decomposition of numbers, each child was given dozens of counting sticks B made of flat rods A made of synthetic resin as shown in Figure 1. Each child learns the composition of numbers by disassembling or composing a predetermined number of counting sticks according to the teacher's instructions. The counting stick b has a rectangular notch c in the lengthwise direction of the counting stick at its end and a square hole d in the lengthwise direction in the middle part, and the counting sticks b are formed with a notch c or a square hole d in the lengthwise direction. In addition to the use of combinations and arithmetic learning, there are also known items that have shapes that can be used as play toys for modeling.

Children tend to lose the counting sticks b, so in order to prevent this, the square holes d should be
For example, 10 counting sticks B are bundled by inserting pin-shaped or clip-shaped sticks as seen in Japanese Utility Model Publication No. 59-55163. It is used to learn composition and decomposition of numbers.

(Problem to be solved by the invention) In order to bundle multiple counting sticks b, the square hole d
The one in which the sticks are inserted into the bundling stick requires the child to hold the bundling stick in one hand, pick up the counting stick B with the other hand, and insert the stick into the stick one after the other, but this is still a step in the development of dexterity. This is a difficult task for children in lower grades who have not done so.

The object of the present invention is to provide a device that can perform this bundling operation relatively easily.

(Means for Solving the Problems) In the present invention, a predetermined number of counting sticks formed by forming notches in the length direction at the ends of flat bars are set to a thickness that fits into the notches of the counting sticks. and converging with a cap provided with a rib having a length corresponding to the total thickness of a predetermined number of counting rods.

(Operation) Place the cap on a desk with the edge of the rib facing upward or sideways, and fit the notch formed at the end of the counting stick into the rib. The counting sticks do not come off even if you move your hands because they fit into the ribs, and if you hold the cap with one hand and fit the counting sticks one after another over the entire length of the ribs, you can count the specified number of sticks. A rod can be placed in the cap.

Since the cap does not need to be held by hand and the counting sticks can be held with both hands, even children in lower grades with insufficient dexterity can easily collect the counting sticks.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. In FIG. 2, reference numeral 1 denotes a counting bar made of synthetic resin and having the same shape as that shown in FIG. 1, which is made of a flat bar 2 and has notches 3 formed in both ends in the length direction. Reference numeral 4 denotes a counting bar having a thickness approximately equal to the width d of the notches 3 of the counting bar 1 and a length l corresponding to the thickness of a predetermined number of the counting bar 1, for example 10.
4 shows a cap with a rib 5 having

The cap 4 has end walls 6, 6 at both ends of the rib 5.
, a bottom wall 7 perpendicular to the lower side of the rib 5, and a side wall 8 perpendicular to the end walls 6, 6 and the bottom wall 7 and parallel to the rib 5, forming a substantially box-shaped structure. an edge 9 of and an edge 10 of the end walls 6, 6 connected thereto,
10, a slope 11 that slopes inward was formed.

A predetermined number of counting sticks 1, for example 10, are placed in the cap 4, and from this, for example, 3 are taken out according to the teacher's instructions, and after confirming that the number of counting sticks 1 remaining in the cap 4 is 7, the number is calculated. It is used for classes to understand disassembly, but after use, the cap 4 is placed horizontally on a desk as shown in Figure 3, and while holding the cap 4 with one hand, the student counts with the other hand. The rod 1 is inserted from its end so that the notch 3 fits into the rib 5. The counting sticks 1 are inserted one after another along the entire length of the rib 5, but there is no need to lift the cap 4 by hand when inserting them, and the cap 4 and the counting sticks 1 inserted into it remain in the same state even if you remove your hand. Since it holds the counting stick 1, even children with poor dexterity can easily perform the task of converging the counting stick 1. In addition, the length of the rib 5 is a predetermined number of counting rods 1
Therefore, by fitting the counting stick 1 into the rib 5 until it reaches its full length, a predetermined number of ribs can be bundled without counting the number of ribs.

When a predetermined number of counting sticks 1 are arranged in the cap 4, as shown in FIGS. 3 and 4, if the cap 4a is fitted to the other end of the counting stick 1, the counting stick 1 can be easily inserted. It never comes off from cap 4.

(Effects of the invention) As described above, according to the present invention, since the counting sticks having notches at the ends are converged using the cap with ribs, the counting sticks can be converged without holding the cap by hand. It is convenient for children who lack dexterity to easily collect the predetermined number of counting sticks, as they can be used to complete the task and fit the counting sticks until the ribs are full. have
