The subject of the invention is a set of a fastening pin and a skirting board connector.

Application description WO 02/066764 discloses a skirting board fastened to the wall with a connector. The connector is a plate whose one end has an offset ending with an elastic blade, and the other end of the plate is ended with a perpendicularly positioned foot which enables resting the connector on the floor while marking the spot where the pin hole is to be drilled in the wall, and enables fastening connectors on the proper elevation. The connector has at least one elongated hole through which it is fastened to the wall by the pin.

The practice of fastening skirting boards proves that holes for fastening pins are not drilled perpendicularly to the surface of the wall. Because of little distance from the floor and the danger of damaging (scratching) its surface by the drill, there is a natural tendency towards lifting the handle of the drill away from the floor, and as a result the hole for the pin is usually made at an oblique angle to the floor surface. As a result of such positioning of the hole, the fastening pin presses the upper part of the connector more tightly.

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. However, before the protrusions lock the pin against

taking it out of the hole, there is some play within the limits of resiliency of the protrusions due to which the fastened element is not fastened rigidly.

Application PCT/PL2004/000085 discloses a clip for joining connectors of the skirting board on the outer corner of the wall. The clip has the form of a plate with a narrowing, and the clip has protrusions which co-operate disconnectably with the holes of the connectors of the skirting board. Distances between protrusions of the clip and distances of the holes from the edges of the connectors are so selected that, after the assembly, the connectors are in contact with each other on the edge of the wall. This solution enables firm fastening of the outer corner element on two connectors of which only one is secured to the wall, but it requires using an additional connecting element.

A set of a fastening pin and a skirting board connector containing a pin provided with protrusions and stabilizing fins and a connector with a wall having a blade at its upper end and a distancing foot at its lower end, characterized by that the connector has at least one offset with an elongated hole, wherein the fastening pin is placed, where the offset is in the form of strips separated by side slots made in the wall of the connector and has stabilizing protrusions, and the head of the pin on its lower part has protrusions whose shape matches the protrusions of the offset. When the pin is thrust into the hole, the offset is resiliently deflected, which, upon releasing the pressure, causes tension in the protrusions of the pin and rigid fastening of the connector.

The fixing protrusions of the offset are tooth-shaped in their cross-section, their tips directed upwards, while the protrusions located at the bottom of the pin in their cross-section are tooth-shaped with their tips directed upwards.

Preferably, the surface of the offset is positioned obliquely towards the surface of the wall of the connector adjacent to the wall of the room, and the offset in the lower passage into the wall of the connector, has a narrowing in its cross-section. The narrowing eases deflection of the offset when the pin is thrust into the hole in the wall.

The hole of the connector has a widening with a guiding protrusion whose shape matches the groove situated between the protrusions of the pin and running along the core thereof. This eases correct positioning of the pin towards the

connector, which is important because of co-operation of the protrusions of the head of the pin and protrusions of the offsets.

The connector may also be provided with shallow recesses on the surface of its wall adjacent to the wall of the room. In this embodiment, it is possible to fasten the connector to the wall using an adhesive.

The connector at its side ends has protrusions and dents, with protrusions on one side thereof correspond with dents on the other side. The protrusions and matching dents enable integration of connectors on the corner of the room wall.

The offset of the surface of the connector at the hole enables self-adjustment of its contact surface with the head of the pin, and results in the connector being pressed with equal force over the entire surface of its contact with the wall. Moreover, the smaller cross-section area of the connection of the offsets enables their deflection during the assembly, which results in continuous pressure of the connector on the wall, caused by the resiliency force of the material.

The subject of the invention is presented in an embodiment in a drawing where Fig.1 presents a perspective view of the pin; Fig. 2 - a view of the pin in the direction "W" shown in Fig. 1; Fig. 3 - a view of the connector; Fig. 4 - a cross- section of the connector fastened to the wall; Fig. 5 - a view of the corner of the wall with fastened connectors; and Fig. 6 - detail "A" of Fig. 5.

The fastening pin I is provided with protrusions 2 and stabilizing fins 3, and has a flattened part 4 where the core joins the head. The head of the pin 1 in its bottom part is provided with protrusions 7 perpendicular to the flattened part 4, which in cross-section are tooth-shaped with their tips directed downwards. Protrusions 2 are so located on the circumference of the core of the pin that they form a groove 8 which runs along the core of the pin 1.. While manufacturing the pin, protrusions 2 are not made in the spot where to groove is to be located.

Connector 6 of the skirting board (not shown in the drawing) has offsets 1_1_ with elongated holes 5, wherein the fastening pin is inserted. Offsets H are in the shape of strips separated by side slots 12 made in the wall of the connector 6 and are provided with fixing protrusions 13. Protrusions 13 are tooth-shaped in their cross-section, their tips directed upwards, and they match the shape of protrusions 7 situated on the bottom part of the head of the pin 1. The hole 5 of the connector 6

has a widening IQ with a guiding protrusion 9 whose shape matches the shape of the groove 8 located between protrusions 2 and running along the core of the pin JL The surface of the offset H is positioned obliquely to the to the surface of the wall of the connector 6 adjacent to the wall of the room, and offset H in the lower passage into the wall of the connector, has a narrowing 15 in its cross-section. The narrowing 15 results from smaller thickness of the strips of the offset H and from the widening of IQ of the hole 5. The connector 6 is terminated at its sides with tongues \7_ and dents 16, wherein tongues 17 on the one side correspond with dents 16 on the opposite side. The tongues 17 and the corresponding dents 16 enable integration of connectors 6 on the corner of the wall of a room, as shown in the drawing (Fig. 5 and Fig. 6). Such integration of connectors enables firm fastening of the outer cover masking the ends of the skirting boards (not shown in the drawings).

Moreover, the connector 6 is provided with shallow recesses on the surface of its wall adjacent to the wall of the room. Such embodiment enables fastening the connector to the wall using an adhesive.

The spots for making holes in the wall of the room are marked using the connector 6, the foot being rested on the floor. To fasten connectors 6 to the wall, the pin 1 inserted to the hole 5, using the widening ^Q and the guiding protrusion 9, in such manner that the flattened part 4 is situated between the strips of the offset H. Then, pressing the connector 6 to the floor, the pin 1 is inserted into the hole in the wall of the room. In the final stage of thrusting the pin 1 into the hole in the wall, it is possible to correct position of the connector 6, as protrusions 13 of the offset H and matching protrusions 7 on the bottom surface of the head of the pin 1 enable moving the connector 6 towards the floor. While the connector is being fixed to the wall, protrusions H deflect to correct imperfections in the making of the holes, which, after releasing the pressure, causes tension in the protrusions 2 in the hole in the wall so that the connector 6 is rigidly fastened to the wall. The oblique position of the surface of the offset H in respect to the surface of the wall of the connector 6, and the narrowing 15, enable deflection of the offset.
