Abstract

A mechanical educational device for making the learning of simple multiplication tables more interesting has a ring shaped body comprising upper and lower sections A, B rotatable through 360 degrees with respect to each other. The main ring shape body A, B is held in within sections C rotatable about the main ring. Typically, the device is of plastic and has 4 inch diameter.

Description

TABLE 1 WISE 2351595 MECHANICAL - EDUCATIONAL - PUZZLE Table Wise' was

conceived because most people think that learning their times tables is a very boring process and certainly not any In at all. With 'Table Wise' you can have hours of fun individually or with a group of friends, trying to complete the puzzle. By making it fun, the "chore" element of learning the tables is taken away.

THE OBJECT The object of 'Table Wise' once it has been jumbled, is to realign the correct question against the correct answer by means of rotating A, B and C. To do this all twelve vertical sections C for each times table must be aligned with the correct horizontal solution. As there are several alternative placements giving the same solution, this seemingly simple task is further complicated.

Table Wise' would be made from resilient plastic that is both very strong, in case of rough handling and to assist the sliding sections by being self lubricating.

The usual way for tables to be written is 1 x 1 = 1, on 'Table Wise' this process will be split into two sections thus, I x 1 =' will be written on section C and the answer 'I' will be written on the main body A and B. In the axis 90 degrees to the main body there are six equi-spaced rotating sections C made up of twelve independent sliding captive sections. The main body A and B can be rotated horizontally to line up the vertical sections C with a different set of answers and again the vertical sections C can be rotated. This process of rotating one axis and then the other can be repeated as often as desired to jumble the puzzle up.

TABLE WISE

Figure 1 Table Wise' is a 4 inch plastic ring made up of two main body parts A and B. These parts rotate about their horizontal captive joint D, one half holding the other captive so that the ring shape is maintained at all times.

Figure 2 The main body A and B can be rotated via the captive joint D that allows the main body 360 degrees movement in either direction. The six vertical sections C are made up of twelve independent sections positioned with six in the top half of the body A and six in the bottom half of the body B. Section C can also rotate through 360 degrees in either direction, around the main body.

Figure 3 & 3.1 Section C is numbered 1 - 12 and six numbers are captive in the top half of the main body A and the other six sections of C are captive in the bottom half of the main body B. Figure 4 Shows complete side view of unfolded shape. In the top line the puzzle is solved. In the second line A has been rotated one place to the left against B. In the third line section C has been rotated one place downwards. This rotation of one axis and then the other in any number of places or either direction gives the puzzle a vast number of jumbled positions. Although, there is only one correct position possible to complete the puzzle successfully.

Figure 4.1 & Shows Figure 4 m 3D view - rotation of A against B. TABLE WISE

With the vertical sections numbered 1 - 6 on the main body A and 7 -12 on the main body B, it is possible to rotate A against B so that section 1 on the top half is lined up with section 7 on the bottom half. Likewise 2 on the top will line up with 8 on the bottom and so on all the way around the main body.

Figure 5 Shows the plan of 'Table Wise' Figure 5.1 Shows the side view of 'Table Wise' Figure 6 Shows a cross section through section C.

This description is for six of the twelve times tables. There would be a version of 'Table Wise' covering all twelve times tables, which although operated in the same manner, would be larger and infinitely more complex.

Claims

CLAIMS TABLE WISE

1) A hand held ring made up of two interlocking halves, one top and one bottom, these two sections can rotate 360 degrees against each other via the captive ring and maintain the ring shape at all times.

2) A ring as claimed in claim 1 that has sliding sections 90 degrees to the main ring that rotate 360 degrees, these sections are made up of twelve independent captive sections.

3) A ring as claimed in claims 1 and 2 that would be made of resilient plastic and have the first siX of the twelve times tables on the smaller version and all twelve times tables on the larger version, printed on the various moving sections.
