Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pin-shaped connecting member for connecting a plurality of wooden block elements having holes, for example, which are made of wood, and in which the connecting member has a tubular portion with longitudinal slits. The slitted portion has an outer diameter somewhat larger than the hole diameter of the block element, and is further provided with a horizontal slit extending over a portion of the body at right angles to the vertical slit. It pertains to a structure that is vertically divided into a plurality of interconnected segments.

In the known pin-shaped coupling elements of the above type, the segments formed by the transverse slots are each able to exert their own spring action, so that the holes in the block elements have different dimensional tolerances. It is possible to adapt each segment of the coupling member to the diameter of the hole of the block element in question without being influenced by the other segments, even if the coupling member is Therefore, in such a connecting member, although the connecting member fits tightly in one hole, it seems to have only a small frictional force or no frictional force in other holes. things are avoided. Therefore, with the above-mentioned connecting member, it is possible to connect the block elements even if the dimensions of the block elements are imprecise.

However, this type of connection of the block elements is based solely on frictional forces, so that if the load on the connection is high, the connection between the block elements can no longer be guaranteed.

The object of the invention is to improve the above-mentioned known construction so that, in addition to the plug-in connection due to frictional forces, the possibility of a connection between block elements that is resistant to tensile forces is achieved.

According to the present invention, this problem can be solved by setting the number and position of the horizontal slits that divide the longitudinally slitted portion of the connecting member to suit the dimensions of the block element having a plurality of intersecting holes. When the connecting member is inserted into the hole of each wooden block element to be connected, at least one transverse slit of the connecting member is inserted into the hole of the wooden block element into which the connecting member was inserted. and is adapted to be located within the intersecting holes, into which an insert member having a web that engages with the transverse slit is inserted and supported within the intersecting hole. This problem has been solved in that the insert is provided with a collar that fits into the intersecting hole and a head that rests on the outer circumferential surface of the block element.

In order to establish the connection, the connecting member is inserted into the mutually aligned holes of the two block elements that are in contact with each other, and the vertical slit of the connecting member is positioned at right angles to the vertical slit. A spring action is produced by the horizontal slits,
This spring action provides a frictional connection to the relevant wooden block elements. The interval between each horizontal slit and the interval between the edge of the connecting member and the horizontal slit are set in accordance with each dimension of the wooden block element, so that the hole in the wooden block element that receives the connecting member is formed. It is ensured that at least one transverse slit is located within the area of the hole intersecting the . The insert member passes through the above-mentioned cross hole of the wooden block element,
The insert is inserted until the web located on the insert engages the transverse slit. By supporting the insert in the cross-hole and at the same time engaging in the transverse slot, a locking effect is created which connects the corresponding wooden block elements to one another in a strong manner against tensile forces. Ru. As a result, the playing child can arbitrarily choose the connections that he deems desirable for the stability of his wooden model. Furthermore, the value of play increases as many variations of block element combinations can be selected with various levels of difficulty.
The kumiki set is suitable for both infants and older children.

Furthermore, in the present invention, by providing the insert member with a collar, the insert member can be easily inserted into the cross-hole, and its support within the cross-hole is increased. In addition, the head of the insertion member has the function of limiting the degree of insertion of the coupling member, and at the same time,
It functions as a grip to allow the insertion member to be removed again when the connection is released.

The invention will now be explained with reference to the illustrated embodiment.

The tubular coupling member 1 according to the invention shown in FIG. 1 has a longitudinal slit 2 extending therethrough. A plurality of interconnected segments 4 are formed by a transverse slit 3 extending perpendicularly from the longitudinal slit 2 over a portion of the torso.
Each has a unique spring action. With the above configuration, it is possible to connect each of the wooden block elements 5 having holes 6 with different errors, and even if the holes of the block elements to be connected are slightly misaligned, this can be avoided. Connections can now be made. Furthermore, in the example shown, the connecting elements 1 in the bores 6 of both block elements
By using the insert member 7, it is possible to make the above-mentioned coupling effect, which is caused only by the frictional force, strong against tensile force. That is, in a state where the coupling member 1 is inserted into the hole 6 in which the number and position of the horizontal slits 3 are aligned, 1
A set of two transverse slits 3 forming one segment is arranged to be located within a hole 6' which intersects the hole 6 which receives the coupling member 1.
Then, in order to lock the connecting part 1 in the hole 6, the intersecting holes 6' of both machining block elements 5 are inserted.
, the two webs 8 to be engaged in the transverse slit 3
The insert members 7 having the same diameter are respectively inserted.
This plug-in part 7 furthermore has a collar 9 which fits into the cross-hole 6' and which, by co-operation with a web 8 which engages in the transverse slot 3, secures the coupling part 1. work. In order to obtain greater stability, it is possible to connect the two webs 8 to each other via a transverse web 10, which should engage in the longitudinal slot 2 of the connecting element 1. The insert 7 also has a head 11 which contacts the outer circumferential surface of the wooden block element 5, by means of which it is possible to remove the insert during uncoupling.

In addition to the slitted part, the connecting member 12 shown in the embodiment of FIG.
used for installation. In order to fix the wheel-shaped block element 14 in position in the axial direction, a head 15 is arranged on the end face of the unslit portion 13, which acts as a stop. The part of the connecting member 12 that is inserted into the hole 6 of the block element 5 is so arranged that one horizontal slit 3 is located in the center of the cross hole 6' when the connecting member 12 is properly inserted. It is divided by a plurality of horizontal slits 3. In this case, therefore, a plug-in part 7 with only one centrally mounted web 8 is used. By inserting the insert member 7 into the cross hole 6' and simultaneously engaging the web 8 with the transverse slot 3, the connection between the connecting member 12 and the block block element 5 is immovably fixed. . Further, in order to facilitate insertion of the web 8 into the horizontal slit 3, the tip of the web 8 can be made sharp or rounded.
