Definitions

• the subject of the invention is a fastening pin, particularly for fastening objects in floors, walls or the like by inserting same into pre-drilled holes.
• Application PCT/PL2004/000089 discloses a fastening pin provided with resilient elastic protrusions, preferably in the form of tapered geometrical figures, positioned around the core of the pin.
• This embodiment allows secure fastening of the pin in the wall without the use of binding agents or elements expanding the pin in the hole.
• Resilient protrusions bending under slight pressure enable easy placement of the pin in the hole without tools, and at the same time they efficiently lock the pin against taking it out of the hole.
• the fastened elements must not move with respect to one another.
• intermediate elements are used, such as washers with cuts, to increase friction between the integrated elements. The additional elements prevent the elements moving with respect to one another.
• the essence of the solution consists in that the head of the pin on its core side is provided with fixing protrusions, preferably in the shape of tapered 3-D geometrical forms.
• An embodiment of the fixing protrusions is such fixing protrusions which in cross-section have the shape of such geometrical figures as triangles, rectangles, half-circles or trapeziums.
• Practice shows that the most efficient are protrusions shaped as right-angled triangles or harpoon-shaped protrusions. Harpoon-shaped ends of protrusions of the head of the pin allow moving elements being joined with respect to the pin in the last stage of their fastening to the wall of the room.
• Said triangle-shaped protrusions can be positioned radial with respect to the axis of the pin.
• Fixing protrusions placed on the head of the pin are particularly efficient when the fastened element also is provided with protrusions, especially if their shape corresponds to the shape of the protrusions on the head of the pin.

• the head 1, 1' of the fastening pin on the side of the core 2 is provided with fixing protrusions in the shape of tapered 3-D geometrical forms.
• Figures 1 to 6 present heads of the pins with longitudinal fixing protrusions situated in a plane perpendicular to the axis of the core, which protrusions in cross- section have the shape of geometrical figures.
• protrusions 3 in cross-section are harpoon-shaped.
• the head 1 of the pin presented in Fig. 2 is provided with longitudinal protrusions of rectangular cross-section outline, whereas protrusions 5 of the head presented in Fig. 3 in cross-section are shaped as isosceles triangles.
• the head 1 of the pin presented in Fig. 4 has semicircular longitudinal protrusions 6, and in the embodiment presented in Fig 5, protrusions 7 are trapezium-shaped in cross-section.
• Fig. 6 presents head V_ of the pin, provided with provisions 8, which in cross- section are triangular and are situated along the radii.
• Fixing protrusions 9, presented in Fig. 7 and Fig. 8, are in the shape of pyramids, and protrusions JK) from Fig. 9 and Fig. 10 are conical in shape.
• Fixing protrusions are particularly effective when the fixed element also is provided with protrusions corresponding in shape to the protrusions of the head of the pin.
• Fig. 11 presents the manner of using the pin to fasten connector 11 of a skirting board 13.
• the head 1 of the pin is provided with protrusions 3 with harpoon- shaped ends, co-operating with corresponding in shape protrusions 12 of the connector H.
• the harpoon-shaped ends of protrusions 3 of the head 1 of the pin and corresponding harpoon-shaped protrusions ⁇ 2 of the connector H ease movement of the connector H with respect to the pin, towards the floor, in the final stage of fastening the connector to the wall of the room.
