Description

  • The subject of the invention is a self-gripping device comprising self-gripping elements which move in relation to each other or to the axis running through the device on one or multiple planes.
  • Owing to their structure and shape, the devices manufactured so far impose the manner in which combination arising from connections between them are created according to strictly pre-imposed rules which do not allow any deviation from them as they are limited by the connection possibilities.
  • The currently used elements connecting the devices are permanently joined with the device and are its integral part. They take on the form of protruding elements, openings, hooks, loops and surfaces fitting into each other. They are positioned in relation to each other in a certain way which corresponds to the manner and principle of connecting where any deviation results in a lack of connection or a forced connection forming tensions. Such tensions may lead to the disconnection of the devices.
  • Document WO-A1-2010/050831 features a three-dimensional self-gripping device comprising at least three interconnected elements placed in a common base wherein the element has a head and a stem, where the stem's diameter is smaller than the head's diameter, and/or the stem's circumference is smaller than the head's circumference. The head of the self-gripping device is a three-dimensional solid figure, preferably being close to a semi-sphere or a complex three-dimensional solid in shape. The stem of the self-gripping device has the shape of a three-dimensional solid, preferably a cylinder whose circumference on the x-z plane, which is perpendicular to the straight line axis running through the head, the stem and the base of the device, is smaller than the head's circumference on the x-z plane, and/or its diameter on the x-z plane, which is perpendicular to the axis running through the head, the stem and the base of the device, is smaller than the head's diameter on the x-z plane. The base of the self-gripping device has a diameter and/or circumference which is smaller than, equal to or greater than the stem's diameter and/or circumference and takes the shape of a three dimensional form. The proportion of the stem's length to its diameter is equal or almost equal to, greater or smaller than zero. The axes of the device's stems connected to the base join or do not join at the same point on the base. The stem's axis running towards the base is a curved, straight or broken line. The head and/or the stem of the self-gripping device and/or the base are solids and/or openwork and/or blind openwork. The head, the stem and the base are made of materials of different physical properties and at least one of them is resilient and/or elastic. At least one connection between the head, the stem and the base of the self-gripping device is elastic and/or resilient. The three-dimensional gripping device connects with other three-dimensional self-gripping devices by means of the heads and the stems through clamping and/or hooking the heads with other heads and/or the heads with the stems and/or the stems with other stems.
  • The objective of the invention is to design an inexpensive and simply-constructed three-dimensional self-gripping device which, thanks to its construction, enables the easy gripping of objects and the creation of spatial forms of irregular shapes through the connection of numerous identical devices or their varieties. The self-gripping devices may be used as toy blocks or constructional elements intended for creating complex spatial forms which can be used as an element forming the structures of road surfaces, artificial ski slopes or the device and the connector can be used in reinforcing wires for creating reinforced concrete structures.

The connection between the devices is effected when the heads ( g ) of the gripping elements ( a ) are hooked to each other and/or the heads ( g ) are hooked to the stems ( e ) in the event when the sum of diameters of three neighbouring heads ( g ) is smaller than the sum of the distances between them and the length of the stem ( e ) is larger than the diameter of the head ( g ). The connector ( L ) and the module ( m ) and the gripping elements ( a ) are made of materials of different or identical physical properties, preferably of resilient, elastic and low friction coefficient materials and/or non-resilient materials. The heads ( g ) of the griping elements ( a ) have smooth and/or ridged surfaces so that they can become connected with other heads [a(1) ] of the device ( x ) of the same type. The heads ( g ) of the gripping elements ( a ) have smooth surfaces and/or surfaces with the parallel cut grooves ( t ) lying in the cut-groove ( t ) width distance from each other. The connector ( L ) is a three-dimensional solid figure, preferably with a shape being close to a solid of revolution or polygon, and that it connects the modules ( m ) in a way enabling them to revolve in relation to each other.
  • The main features of the self-gripping device are its spherical or cylindrical shape as well as the changeable position of gripping elements of the neighbouring modules of the device in relation to each other.
    Due to the changeable position of the gripping elements in relation to each other, the self-gripping device gains a greater ability of fitting into the gripping elements belonging to other devices of this type.
