Problems solved by technology

The disadvantage of this fastening device is that, in the initial position of the spring-loaded element, the distance between the contact surface of the head and the contact surface is fixed and thus the connecting force acting on the connecting piece to be connected is fixed. of

Embodiment Construction

[0055] figure 1 Shown is a fastening device 1 which is provided for connecting two plates 2 to each other. The fastening device has a fastening mechanism 3 , a first washer 4 and a second washer 5 .

[0056] The fixing mechanism has a head 6 and a pin 7 . The head 6 has a head contact surface 8 composed of two partial surfaces. Mounted on the pin 7 is a contact surface 9 consisting of two sections, which is opposite the head contact surface 8 , these sections being formed on spring-loaded elements so that the section of the contact surface 9 The segments can be pressed in in the direction of the longitudinal axis of the pin 7 . In the description of the present invention, the concept of "relative" also includes as in figure 1 The arrangement of the fastening mechanism shown in , wherein a section of the contact surface 9 is arranged rotated by 90° about the longitudinal axis of the pin 7 relative to the subsurface of the head contact surface 8 . However, it is also possib...

Abstract

The invention relates to fastening device with a fastener, a first washer, and a second washer. The fastener has a head with a head contact surface and a pin which extends outwards from the head alonga longitudinal axis, and the pin has a fastening end with a contact surface opposite the head contact surface. The first washer has an opening, which is suitably large enough to allow the pin to passthrough the opening, and a wedge-shaped sub-portion. The second washer has an opening which is suitably large enough to allow the pin to pass through the opening and to allow a rotation of the secondwasher relative to the fastener about the longitudinal axis of the pin. The second washer contacts the wedge-shaped sub-portion and moves along the surface of the wedge-shaped sub-portion when the second washer and the fastener rotate relative to each other about the longitudinal axis of the pin.

Description

technical field [0001] The invention relates to a fastening device with a fastening mechanism having a head and a pin extending from the head along a longitudinal axis, the head having a head contact surface, wherein the pin has a fastening end with a contact surface, The contact surface is opposite to the head contact surface. Background technique [0002] Screws are known as fastening means which have a nut which is screwed onto the threaded pin of the screw, or screws which are screwed into a threaded hole. The connecting parts that need to be fixed to each other are arranged between the head of the screw and the nut screwed onto the threaded pin. However, screw connections have the disadvantage that a relatively time-consuming fastening process is required. As a result, for example, the screw must be turned several times until it is screwed sufficiently deep into the threaded hole. In the case of through screws it is required that the pin end be provided with a nut an...
