Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an abacus counting device that eliminates the fear of abacus counting during calculation and speeds up the counting.

Abacus counter-setting devices are already known, but in all of these, a rod for operating beads is moved by pushing an operating body protruding from a frame in a direction parallel to the limbs to which beads are attached.

During calculations, the abacus is generally held fairly tightly by the upper and lower frames with the left hand to prevent it from moving unnecessarily.

Therefore, if you place your finger on the operating device for bankruptcy when calculating, there is a risk of accidentally incurring the bankruptcy, so it is necessary to keep your fingers and fingers away from the operating device for bankruptcy during calculation, so that the calculation ends. Since it is necessary to move the hand and finger to the operating body each time the calculation is made, the calculation is delayed by that amount, making it unsuitable for competitions.

In addition, since the operating body is a stick whose tip is pressed with the fingers, depending on the position of the left hand holding the abacus, the hand becomes quite thick (needs to be moved) when the abacus is held, and the operation Since you will be searching for your body, your bankruptcy will be delayed further.

The present invention solves the above problems.

First, the first invention will be explained with reference to FIGS. 1 to 9. Reference numeral 1 denotes a pair of side frames, with an upper frame 2 fixed between one end and a lower frame 3 fixed between the other ends.

4 is a beam placed near the upper frame 2 and fixed between the side frames 1 and 1, 5 is a beam that penetrates the beam 4 and is fixed between the upper frame 2 and the lower frame 3, and five beads are attached to the upper side of the beam 4. 6 and a portion 7 are attached to the lower side, respectively.

Reference numeral 8 denotes a plurality of links made of plates or rods, which are placed over the back surface of the beam 4, and their center portions are pivoted to the beam 4 by a shaft 9.

Beads 6.10 are arranged on the back side of the abacus, parallel to both sides of the beam 40, and connectable to the five bead 6 and the side surface of a portion of T. A pair of rods that move γ and have a length that spans almost the entire length of the beam 4, each of which has a link 80.
It is pivoted on both ends.

Reference numeral 11 denotes an operating body in which the link 8 is projected toward the upper frame 2 from a position overlapping the shaft 9 attached to the beam 4;
The link 8 is fixed to the link 8 by being formed integrally with the link 8 or formed separately and fixed to each other.

Therefore, if the free end side of the operating body 11 is swung in a direction parallel to the upper frame 2, the ring 8 will rotate and the rod 1
0°10 is away from beam 4 or close to beam 4.

In the example shown in FIGS. 2 to 4, the free end of the operating body 11 is inserted into the recess 13 through the insertion hole 12 provided in the upper frame 2, and
The operating body 11 is engaged with a part of a movable body 14 provided on the outer surface of the movable body 14 so as to be slidable in a direction parallel to the outer surface of the movable body 14, so that the operating body 11 is caused to swing by sliding the movable body 14.

In the example shown in FIG. 2, the end of the operating body 11 is inserted into the pipe-shaped engagement protrusion 15 provided on the back surface of the movable body 14, and in the example shown in FIG. Although the ends of the body 11 are overlapped, either may be used.

When the engaging protrusion 15 is made into a pipe shape as shown in Fig. 2,
It is suitable that the inner diameter thereof is larger than that of the end of the operating body 11 so that the operating body 11 can be swung easily.

In these examples, the moving body 14 is slidably attached to the upper frame 2 and inseparably attached thereto.

FIG. 2 shows that a dovetail 16, which is long on the back side of the movable body 14 in a direction parallel to its sliding direction, is slidably engaged with a dovetail groove 17 fixedly provided in the upper frame 2, so that the movable body 14 can be moved. This is an example in which the body 14 is slidably and non-separably attached to the upper frame 2.

The dovetail 16 and the dovetail groove 17 may be provided only on one side of the engagement protrusion 15.

FIG. 4 shows a pin 19 inserted into a long hole 18 passed through the upper frame 2 in the length direction of the operating body 11, and fixed to the movable body 14, and the head of the pin 19 is engaged with the outside of the long hole 18. By stopping the movable body 14, it is possible to slide the movable body 14, but it is impossible to separate it from the upper frame 2.

5 and 6 show still another example, in which a mounting protrusion 20 provided on the operating body 14 and movably fitted into the upper frame 2 has a mounting protrusion 20 that is long in the moving direction of the movable body 14 and extends in the front and back directions of the abacus. A pin 22 fixed to the upper frame 2 is inserted into the long mounting hole 21 provided.

However, the invention is not limited to these examples. 23 moves the operating body 11 and the movable body 1 in the direction of bringing the rod 10 closer to the beam 4;
This is a spring provided in the recess 13 to bias the recess 4.

To complete the calculation using this device, the moving body 14 is slid to the left along the upper frame 2 against the force of the spring 23 after the calculation is completed.

In the drawing, the back side of the abacus is shown, so it is on the right side.

Then, the engaging protrusion 15 of the movable body 14 causes the operating body 11 to swing about the shaft 9 as a fulcrum.

When the operating body 11 swings, since the operating body 11 and the link 8 are fixed to each other, the link 8 rotates as shown by the arrow in FIG. 2, and the rod 1010 is moved in the direction away from the beam 4.

Since the rod 1010 can be joined to the five beads 6 and the part 7,
With these moves, all beads 6 and 7 are destroyed at the same time.

When the movable body 14 is released after the transaction is completed, the repulsive force of the spring 23 causes the movable body 14, the operating body 11, and the rod 1010 to return to their original positions.

The movable body 14 may be slid back to its original position by hand without being released.

In this way, the moving body 14 that slides along the upper frame 2 is provided, and the link 8 is rotated by the sliding of the moving body 14.

In other words, if you hold the abacus by holding the upper and lower frames 23 during calculation, there is no risk of making a mistake even if you hold down the moving body 14.

In other words, since you can always hold the movable body 14 while calculating, when the calculation is finished and you want to cancel the transaction, you only need to move your fingers slightly in the horizontal direction, and you can complete the transaction without wasting time. can.

Since the movable body 14 can be made longer in the length direction of the upper frame 2, it is possible to always hold the movable body 14 even if the position of holding the abacus changes to some extent.

7 to 9 show other embodiments. In FIG. 7, a connecting body 24 provided on the inner surface of the movable body 14 is pivoted to the end of the operating body 11, with one of them being a long hole. This is also a moving object 14
When you slide the button, the operating body 11 swings accordingly, allowing you to make a payment.

In FIG. 8, the end of the operating body 11 is projected from the insertion hole 12 to the outside of the upper frame 2, and is directly fixed to the movable body 14, so that the operating body 11 can be rotated directly by sliding the movable body 14. This is suitable for simplifying the configuration.

Note that in this example, there may be a slight gap between the opposing surfaces of the upper frame 2 and the movable body 14, or there may be a slight gap between the upper frame 2 and the movable body 14, or
It is suitable that 1 be made slightly slidable in its axial direction.

In the embodiment of FIG. 9, the link 8 is
One end of the operating body 11 is pivotally attached to the movable body 14, and the other end is pivoted to a connecting body 24 protruding from the movable body 14.
When the is slid along the upper frame 2, the operating body 11 is pulled through the connecting body 24, and the link 8 is rotated, and the rod 10.degree.

In this example, the operating body 11 may be fixed to the link 8, and in this case as well, the operating body 11 swings as the movable body 14 slides, causing the link 8 to rotate and the transaction to be made.

When the movable body 14 is released after the discharge, everything returns to its original state due to the repulsive force of the spring 23.

The operating body 11 in the embodiment shown in FIG. 9 may also have its end fixed directly to the movable body 14 as in the embodiment shown in FIG.

In the embodiments shown in FIGS. 7 to 9, the movable body 14 is pivoted or fixed to the operating body 11, so that alone can make the movable body 14 inseparable from the upper frame 2. However, in the embodiments shown in FIGS. It is also possible to use a means for fixing the movable body 14 in combination.

In these embodiments, the spring 23 connects the operating body 11 and the movable body 1.
4 is energized.

However, in the embodiments shown in FIG. 2 and FIGS. 7 to 9, if the movable body 14 is returned to its original position by hand after the transaction is completed, the operating body 11 is returned to its original position, and the rod 10 can be returned to both sides of the beam 40. .

In any of the embodiments shown in FIGS. 2, 4, and 7 to 9, if one of the beads 67 is moved for calculation without pressing the movable body 14 after the transaction, the rod 1010 can be moved. Since everything returns to its original state through the spring 23
It is possible to exclude

FIG. 10 shows an embodiment of the second invention, in which the link 8 is moved by pushing the operating body 11 in the direction of the lower frame 3 by sliding the movable body 14.
The operating body 11 is pivoted at a position away from the shaft 9 and far from the movable body 14, and the other end is inserted and supported within the recess 13 of the upper frame 2.

A cam 31 is provided on the inner surface of the movable body 14 so as to project from the movable body 14. The cam 31 pushes the free end of the operating body 14 in the axial direction when the movable body 14 is slid along the upper frame 2.

32 is for urging the operating body 11 toward the movable body 14;
This is a spring interposed between the bottom of the recess 13 and the tip of the operating body 11.

Although not shown in this drawing, in order to slidably attach the movable body 14 to the upper frame 2, attachment means such as those illustrated in FIGS. 2 to 6 are employed.

The other configurations are the same as the first invention.

When using this device, the movable body 14 is slid along the upper frame 2.

Then, the cam 31 protruding from the inner surface of the movable body 14 pushes the tip of the operating body 11, moves the operating body 11 in its axial direction, rotates the link 8, and completes the transaction.

If you release the moving body 14 after the settlement is completed, the spring 23.3
With the power of 2, everything will return to normal.

The movable body 14 may be manually slid back to its original position without being released.

Even if the spring 2332 is removed, the scales that operate the device are the first.
This is similar to the invention of

In this way, in the second invention as well, if the movable body 14 is slid along the upper frame 2, the transaction will be canceled.
There is no risk of failure even if the moving body 14 is pressed strongly to fix the abacus during calculation.

Therefore, it is easy to handle the abacus during calculations.
In addition, since the user can keep his/her fingers on the movable body 14 at all times when using the abacus, the user can quickly complete the transaction.

Furthermore, compared to the pressing motion of conventional devices, the sliding motion of the present invention allows the fingers to move more easily and smoothly, which also speeds up the settlement. suitable for doing.

In all the embodiments shown here, the movable body 14 is arranged on the upper frame 2 side, but the movable body 14 can also be provided on the lower frame 3.
In this case, the operating body 11 is made to protrude toward the lower frame 3.

The sliding direction of the movable body 14 at the time of settlement is the direction in which the fingers of the left hand are pulled when the abacus is held, but it is of course possible to slide the moving body 14 in the opposite direction.
