DESCRIPTION:
BRIEF SUMMARY
The invention relates to a fastening mechanism for shoes, articles of clothing, tents or rucksacks etc. with a lace or tape-like tying element.
A fastening mechanism is already known, in particular a clamping mechanism for a shoelace according to EP-B1-0 398 303 of the same Applicant, which comprises a fastening tab and a supporting body having two side walls, between which there is a free space for the shoelace. The free space in the form of a recess comprises a clamping element, which in longitudinal guides arranged in the side walls can be moved from a clamping position into an open position. The shoelace is guided between the clamping element and a stop delimiting the recess opposite the fastening tab and wraps around the clamping element on the side facing away from the stop.
The above tried and tested clamping mechanism has a disadvantage however in that the shoelace runs between the underside of the supporting body and a surface of the shoe, which on lacing the shoe results in a point or linear pressure acting on the surface and thus on the body of the shoe wearer, reducing the comfort of the shoe or article of clothing respectively. Furthermore, it is very a time-consuming and complicated process to insert and guide the shoelace in or through the supporting body. In addition, with a rigid arrangement of the clamping element there is an increased risk of abrasive wear to the shoelace.
The objective of the invention is therefore to create a fastening mechanism which is characterised in that the article of clothing, for example a shoe, is very comfortable for the wearer. Furthermore, the fastening mechanism should be easy to thread, which is desirable in particular in the case of rucksacks or tents.
In addition, the objective is that along an opening of the article of clothing or the rucksack or tent to be fastened as many fastening mechanisms as possible should be arranged consecutively in order to obtain an even and tight fastening of the opening, and/or the tying element should be secured against movement in opening direction.
The said objective of the invention is achieved according to the features of one embodiment of the invention. The surprising advantage is that the tying element does not rest on the upper side of an article of clothing, thus avoiding a point or linear pressure on said surface and increasing the comfort of the article of clothing for the wearer. Furthermore, an angle, defined by a section running into the fastening mechanism and a section of the tying element running out of the latter can be reduced, thus permitting a reduction in the distances between consecutively arranged fastening mechanisms in an opening of an article of clothing and thereby an even and tight fastening of the opening.
An embodiment according to claim 2 is advantageous in that a low-friction movement of the tying element relative to the fastening mechanism is achieved and thus the wear of the tying element is reduced.
A further embodiment of the invention in which the rotary body is a ball and is rotably mounted in opposite openings of the arms is also advantageous in that the low-friction and low-wearing guiding of the tying element is performed on a spherical surface and thus in any dimension, so that both the lacing up and tightening of the tying element can be performed easily.
A still further embodiment in which the rotary body is arranged rotably about an axis of rotation arranged rigidly in the arms is also possible in which wear to the exterior of the reversing element is avoided, and the easy rotational movement of the reversing element is maintained, in particular in the case of a dirty fastening mechanism.
The invention also provides a fastening mechanism in which the rotary body is in the form of a cylinder having cylinder extensions rotably mounted in the opposite openings of the arms, by which the production costs of the fastening mechanism can be maintained without compromising the comfort for the wearer, the low wear and simple lacing of the tying element.
