Description

Reference number: 202 08 9264 · ·* · · · \'**\ · j · .«' Description of the wooden cross:

The wooden cross is a puzzle. It consists of two identical wooden constructions. Both parts have holes (a) that each hold a pin that normally holds the two parts together (after the wooden constructions have been put together and moved only slightly, the pins slip into the hole (b) and can only be removed in the manner described).

The two parts can only be separated again if the cross is rotated on the table and the pins slide back into their holes (a 1+2) due to centrifugal force.

In order for the pins to hold the 2 parts together, both parts are drilled through at the corresponding point (b) (see sketch). For each wooden cross, 4 pins must slip out of the hole and release the 2 individual parts again.

Description

Wooden cross for use as a game of skill

State of the art:

So far, we are not aware of a similar game.

Problem:

The wooden cross consists of two identical wooden structures. Both parts have holes (a) that each hold a pin that normally connects the two parts firmly and generally does not accidentally release them as individual parts. After the wooden structures have been put together and moved only slightly, the pins slip into the hole (b) and can only be opened if the physical principle of centrifugal force is applied. Shaking them does not help either, as at least one of the four pins prevents them from being pulled apart. Even if the wooden cross is rotated on its axis but slips sideways, the parts will not separate from each other.

Solution:

The two structures (referred to as a wooden cross) can only be separated again if the cross is placed on the table and rotated so that the 4 pins simultaneously slide back into their holes (a 1+2) due to centrifugal force and release the individual parts again. Provided the wooden cross is not moved again, the upper structure can be pulled up and you have two individual parts again.

Advantages/meaning:

In adult education/personnel development, this game can be used to demonstrate complex situations and the development of solutions.

Further embodiment of the invention:

The wooden cross can be recreated using many materials and in many sizes and can be used in many different ways.

Explanation of the drawing with label

0 holes a(i+2): 9 mm, 0 holes b: no mm Depth of hole(ai+2) approx. 3.6 mm, hole b goes through.

A second, completely identical piece is placed upside down in the groove and creates a wooden cross that can only be separated in the manner described. The wooden pins cannot fall out of their holes and can move freely.

Claims (1)

Wooden cross for use as a game of skill, consisting of two completely identical pieces that are inserted upside down into the groove and characterized by the fact that it consists of two identical wooden structures (or another suitable smooth material). In both structures there are holes (a) each of which accommodates a pin (4 in total, each structure 2), which (pins) normally firmly connect the two parts.
