System comprising two linings lying on top of one another and a securing means, a method for connecting two linings and a securing means designed as a tension spring

摘要

The invention relates to a system (1) which comprises at least two coverings (101; 201) lying on top of one another in the form of an upper cover (101) and a lower cover (201) and at least one securing means (301; 401), with the coverings (101; 201) at least partially cover and in each case a plurality of openings (105, 106; 205, 206) between an upper side (102; 202) which forms a running surface (103; 203) of the respective covering (101; 201), and an underside (104; 204). Provision is made here for the securing means (301; 401) to be designed as a tension spring (302; 402), the tension spring (302; 402) having a first free leg (304; 404) on either side of a spiral winding (303; 403). and a second free leg (305; 405), wherein the tension spring (302; 402) is guided with the first free leg (304; 404) through one of the openings (105; 106) of the upper covering (101) and on the Upper side (102) of the upper covering (101) rests and wherein the tension spring (302; 402) is guided with the second free leg (305; 405) through one of the openings (205; 206) of the lower covering (201) and on the Underside (204) of the lower covering (201) rests.
