TOY BUILDING SET

Abstract

A toy building set comprising a group of building elements, each having at least one ball 1, 2 arranged on the building element, and where the ball 1, 2 is connected to other parts of the building element via a connection rod 3, 4, and where the toy building set further comprises at least one element having a socket formed by two jaws 5, being arranged and adapted for receiving said ball 1, 2 in order to form a ball and socket joint, and where the cross section of the connection rod 3, from where it is connected to the ball 1 and at least a distance away from the ball 1, is smaller than the cross section of the ball 1, so that it gives a certain degree of freedom for the socket to rotate around the ball 1. The connection rods 3, 4 also comprise connections rods 4 having a relatively large cross section, so that the connection rods 4 with a relatively large cross section reduces the degree of freedom for the socket to rotate around the ball 2.

Description

The present invention relates to a toy building set comprising a group of building elements, each having at least one ball arranged on the building element, and where the ball is connected to other parts of the building element via a connection rod, and where the toy building set further comprises at least one element having a socket arranged and adapted for receiving said ball in order to form a ball and socket joint, and where the cross section of the connection rod, from where it is connected to the ball and at least a distance away from the ball, is smaller than the cross section of the ball, so that it gives a certain degree of freedom for the socket to rotate around the ball.

Thereby it is possible for e.g. a child to build constructions, such as toy figures having articulated body parts.

DESCRIPTION OF RELATED ART

An example of such a toy building set is known from EP patent application no. 856341 disclosing a number of separate building elements that can be connected via ball and socket joints to form an articulated toy figure.

The problem in relation to this kind of toy building sets is that it does not provide many different ways of connecting the separate elements to each other.

In relation to toy building sets it is therefore a constant challenge to provide such building sets that gives the possibility to build many different constructions or figures by using the same basic elements.

This is achieved to a certain degree with the toy building set according to U.S. Pat. No. 579,681, disclosing many different kinds of elements having coupling balls and complementary sockets that can be connected to each other in many different ways to form articulated figures or constructions.

SUMMARY OF THE INVENTION

The main object of the present invention is to provide a toy building set giving the user more different ways of building articulated figures having different patterns of possible movements.

This is obtained by the present invention according to claim 1 further specifying that the group of building elements comprises a first and a second type of connecting rods, and in that the first type of connection rod, at least close to the ball, has a cross section being relatively larger than the corresponding cross section of the second type of connection rod, so that the relatively larger cross section of the first type of connection rod reduces the degree of freedom on which the socket can rotate around a ball carried by the first type of connection rod, than the degree of freedom on which the socket can rotate around a ball carried by the second type of connection rod.

Thereby the same socket can be mounted on two different both balls being connected to a building element by connection rods with different cross sections, and the degree of freedom on which the socket can rotate around one of the balls will be more limited than the degree of freedom on which the socket can rotate around the other ball. Thereby it is possible, with a relatively limited number of different building elements, to build many different figures or constructions and at the same time providing more different patterns of possible movement or articulation of the figure or construction.

In a preferred embodiment the connection rod has an axis of symmetry, and the axis of symmetry extends through the ball carried by the connection rod. In this relation the axis of symmetry can preferably extend through the centre of the ball.

The group of building elements may comprise at least one building element having both a first and a second type of connections rods each carrying a ball. In this way the same building element can provide more different patterns of movement or articulation.

A very simple element can in this relation be provided, if at least two of the balls are interconnected by a common connection rod, and especially if the common connection rod has one end forming the first type of connection rod having its relatively larger cross section near one of the balls, and another end forming the second type of connection rod having its smaller cross section near another ball.

A toy building set according to one or more of claim 4, 5 or 6, characterized in, that at the at least one of the building elements has at least one ball having precisely two connecting rods of the first type extending from it.

In this relation it is further possible that at least one other ball has only one connecting rod of the second type extending from it.

In a further preferred embodiment the socket is formed by two resilient jaws, each having a concave coupling surface facing the other jaw, and having a spacing that ensures that the coupling surfaces on the two jaws lies against opposite sides of the ball, when the socket is mounted on the ball.

In this relation it is advantageous if the concave coupling faces on the jaws extend between two side faces, and in that the distance between the two side faces, and the cross section of the first type of connection rods are selected so that the jaws mounted on a ball carried by two of the first type of connection rods having a common axis of symmetry, can only rotate around the common axis of symmetry of the two connections rods of the first type.

BRIEF DESCRIPTION OF THE DRAWINGS

In the following, the invention will be described in greater detail with reference to embodiments shown by the enclosed figures. It should be emphasized that the embodiments shown are used for example purposes only and should not be used to limit the scope of the invention.

FIG. 1 shows a simple construction built by using one of each of the building elements shown on FIGS. 2, 3 and 4.

FIG. 2 is a side front of a first building element according to the invention.

FIG. 3 is a side view of a second building element according to the invention.

FIG. 4 is a side view of a third building element according to the invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In FIGS. 2, 3 and 4 are shown different embodiments of building elements according to the present invention. From the description below it will be evident to the skilled person that many different embodiments than the ones shown on FIGS. 1, 2 and 3 are possible to suggest in order to provide many different possibilities for building a toy construction, such as a toy figure or the like.

In the FIGS. 2 to 4, the building element has different numbers of balls 1, 2 being connected to each other via two different types of connecting rods 3, 4 where the first type of connecting rods 4 has a cross section being larger than the cross section of the second type of connecting rods 3.

The embodiments according to FIGS. 3 and 4 has identical sockets each formed by two jaws 5 having a concave surface 6 designed for providing a snap fit on any of the balls 1, 2, so that the socket 5 can slide on any of the balls 1, 2 without being released from the ball 1, 2. In FIG. 3 the jaws are shown in a front view, and in FIG. 4 the jaws are shown in a side view.

In this way the ball 1, 2 being connected to a socket will form an articulated ball and socket joint, so that the building elements provide the possibility to build a number or different articulated constructions or figures by using a varying numbers of building elements according to the invention.

As mentioned above it will be possible for the skilled person to suggest other embodiments having more or less balls 1, 2 arranged in many different positions with respect to each other, and be fixed together in their relative positions by means of the two different connection rods 3, 4. The two embodiments shown in FIGS. 3 and 4 shows that the connecting rods 3, 4 are arranged along the same axis of symmetry S shown by the dotted line, and in FIG. 2 the connecting rods 3, 4 are arranged along more symmetry lines arranged in common plan, and where only one is shown in the figure. It will be apparent that the skilled person can come up with other arrangements of symmetry lines arranged in 2 or 3 dimensions without departing from the idea of the present invention.

In this relation the building element according to FIG. 2 is designed to be used as a corpus element for building a bone structure for a toy figure, and the building elements according to FIGS. 3 and 4 could be used to be connected to the building element according to FIG. 2 in order to form a bone structure for limb parts of the toy figure.

In FIG. 4 is now shown a simple construction built by using the building elements according to FIGS. 2, 3, and 4. The building element according to FIG. 3 is mounted on the building element according to FIG. 2 by snapping the jaws 5 on a ball 1 being carried by a connection rod 3 having a relatively small cross section, and the building element according to FIG. 4 is mounted on a ball 2 being carried by two connection rods 4 having a relatively larger cross section.

Hereby the jaws 5 and thereby the building element according to FIG. 4 can, due to the relatively small cross section of the connecting rod 3, rotate around the ball 1 in all directions, and with a high degree of freedom.

On the other hand the relatively large cross section of the connection rods 4 carrying the ball 2 on which the jaws 5 according to the building element shown in FIG. 4, substantially only allows this building element to rotate around the symmetry axis S when sliding on the ball 2.

In this way the building elements according to the present invention provides more different options for building a large number of different constructions or figures.
