Abstract

An arithmetic teaching aid consists of a horizontal bar supported at each end by a semi-circular disc. The bar provides the support for a series of clip-mounted discs bearing numbers or arithmetical symbols. The Bar and symbols are waterproof and designed for use under water by children and young people.

Description

The The invention relates to a device for diving and learning underwater. Diving figures and diving elements more usual Design is available in different sizes and shapes. We know diving rings, Diving animals, dip sticks and diving balls.

Of the Disadvantage of these known diving equipment and diving figures is that that they alone serve the purpose of lifting them up from the pelvic floor pick up.

A The exception is the underwater "butter-cheese-eggs game" in which two partners play a kind of board game underwater.

With This exception is the cognitive demands made on children and adolescents when diving in the water are made, rather low.

Of the in claim 1 protection invention is based on the problem a diving device too create that primarily under the water surface different learning tasks allowed.

This Problem is solved with the features listed in the protection claim 1.

With The invention is achieved that with numbers, letters or others Symbols labeled discs that have a holder on their back, can be put side by side on a stick. Thereby sit at both Ends of the rod feet that Keep the entire underwater learning stick at the bottom of the pool.

The circular shape of the feet is on a place interrupted so that the dive computer in swimming pool with gradient stays in place and does not roll down.

An embodiment of the invention will be described with reference to 1 to 4 explained. Show it:

1 The underwater learning stick with rod ( 1 ) with lateral feet ( 2 ) and attached washers ( 3 ). In this example, with numbers and arithmetic.

2 Partial view of the underwater learning rod with a diving number ( 3 ) and a foot tilted sideways ( 2 ).

3 Part of the underwater learning rod viewed from the side with an attached immersion disk ( 3 ) and a holder ( 4 ) for securely attaching the dip wheels to the rod ( 1 ).

4 Another partial section of the underwater learning rod with view diagonally from below. With rod ( 1 ) Diving disc holder ( 4 ) and immersion disk ( 3 ).

Claims (11)

Underwater learning rod for arithmetic, forming concepts and learning underwater, characterized in that immersion discs ( 3 ) on its back a bracket ( 4 ), by means of which they are arbitrarily preferably on a rod ( 1 ) can be placed. Underwater learning rod according to claim 1, characterized in that the immersion discs ( 3 ) together with the holder ( 4 ) sink to the bottom due to their material properties in the water. Underwater learning rod according to one of the preceding claims, characterized in that the rod of the underwater learning rod has a non-floating foot on each side ( 2 ), which holds the entire underwater learning bar on the ground and this circular foot is preferably interrupted at one point, so that the underwater learning bar does not roll away in sloping swimming pools. Underwater learning rod according to one of the preceding claims, characterized in that these feet ( 2 ) a sufficient distance of the rod ( 1 ) to the bottom, thereby substantially facilitating the placement, displacement and removal of the dip wheels on the rod, Underwater learning stick after one of the previous ones claims characterized in that the immersion discs of a waterproof, non-floating material that can be used with numbers, Letters or other symbols be printed or inscribed can. The immersion disks preferably have a diameter from about 10 to 12 cm. Underwater learning stick after one of the previous ones claims characterized in that instead of labeled or printed Washers, washers cut out (sawn) also in their original form for example, manufactured and used as numbers or letters can be. Underwater learning stick after one of the previous ones claims characterized in that instead of numbers and letters just as well symbols, signs, shapes and figures on the staff systematically can be ordered. Underwater learning rod according to one of the preceding claims, characterized in that by the systematic stringing together of For Men and figures on the rod simple puzzle can be formed. Underwater learning stick after one of the previous ones claims characterized in that by means of this rod in size, color, Strength and form objects differing from each other below and above water surface can be systematically organized. Underwater learning stick after one of the previous ones claims characterized in that the immersion discs are not in a circular shape are bound, but also consist of other geometric shapes can. Underwater learning stick after one of the previous ones claims characterized in that instead of a straight bar alternatively Also a curved bar can be used.
