    The elastically dilatable pin type connector (1) is used to joint the timber components of a child's construction game. It makes the joint by being pushed axially into aligned bores in abutting components, and adapts in the radial sense to fit the individual bores whilst tending to expand radially and grip the walls of the bore. The connector may comprise a length of circular hollow section with a continuous longitudinal barrel slot (2). Arcuate transverse barrel slots (3) are bisected by the longitudinal slot. The segmental cantilever flaps (4b) flex to adapt to bore dimensions.

    The invention relates to toys, in particular, pin joints for connecting wooden parts of a children's designer with openings.
    A pin connecting element for wooden parts of a children's designer with holes is known, having a tubular section with a longitudinal slit. The connection of the parts of the children's designer is achieved by friction of the connecting elements in the holes of the SI.
    However, such joints require small tolerances both for the manufacture of the parts themselves and for the manufacture of the connecting elements. The connection of the parts is difficult due to the influence of humidity due to the influence of the sun rays, etc.
    The purpose of the invention is to increase the reliability of joining parts that do not have exact dimensions.
    The goal is achieved by the fact that in a pin connecting element for wooden parts of a children's designer with holes having a tubular section with a longitudinal slit, the outer diameter of the tubular section is larger than the diameter of the hole in the part, while the tubular section is divided into sections in the longitudinal direction , made around the circumference n crossing the longitudinal slit.
    FIG. 1 shows the connecting element; in fig. 2 - connecting element together with designer parts; in fig. 3 - the same
    2 expansion element.
    The pin connector of FIG. 1) has a tubular section 1
    3 longitudinal slot 2. Tubular,
    Section 1 is longitudinally divided into parts 3 and 4 by slits 5 circumferentially made and intersecting longitudinal slot 2. Due to this, parts b can be joined, the openings 7 of which have different tolerances or a slight offset.
    The connecting element (Fig. 2) has an uncut section 8, the diameter of which is smaller than the diameter of the holes 7 in parts 6. On the front side of section 8 there is a head 9 that restricts the insertion of the connecting element and also serves to fix the connected parts of the designer.
    To connect the parts, they are aligned so that the holes 7 coincide. The connecting element is then inserted into these holes, with the bevels 10 or the rounding Fia on the front side and on the slot 5 facilitating its insertion or removal. Parts 3 and 4 of the tubular section 1 correspond to the external dimensions of the parts; therefore, each part corresponding to the part has a spring action independently of the adjacent segment.
    In order to increase the friction of the part of the tubular section 1 in the hole 7 of the part 6 (Fig. 3), an expansion element 11 is inserted into it, the conical surface 12 of which splits the walls of the section, pressing them against the wall of the hole 7 of the part 6. The expansion element 11 at the end of a larger diameter It has a head 13, which limits the insertion of the connecting element and also facilitates the removal of the trailing element 11 when disassembling the connection. The expansion element 11 can be made hollow,
