Abstract

The invention relates to a device for holding a head of a pin of a component, said device having a receiving space which defines an opening via which the head of the pin can be inserted; a spring element disposed in the receiving space; and a path limiter which is disposed in the receiving space. The spring element has a receptacle for the head of the pin of the component, and the straight line which connects the geometric center point of the opening to the geometric center point of the receptacle forms a reference line. A curved or bent receiving section of a spring arm of the spring element is provided as part of the receptacle. The receiving section has at least one distance point which is arranged furthest from the reference line than other points along the extension of the curved or bent receiving section.

First claim

What is claimed is:

1. A device for holding a head arranged on a component, said device comprising a receiving space defining an opening, via which the head can be inserted into the receiving space from the outside, and a spring element arranged in the receiving space and a path limiter arranged in the receiving space, wherein:
the spring element including a receptacle for the head of the component,
the straight line that connects the geometric center point of the opening to the geometric center point of the receptacle forming a reference line, and the plane that includes the geometric center point of the opening and is perpendicular to the reference line forming a reference plane,
a curved or bent receiving section of a spring arm of the spring element is provided as part of the receptacle, the curved or bent receiving section having at least one distance point, which is arranged furthest from the reference line in comparison with other points along the extension of the curved or bent receiving section,
in relation to the position of the receiving section relative to the reference plane, a blocking section of the spring arm, with respect to which the curved or bent receiving section is designed as a recess, is closer to the reference plane than the receiving section,
the path limiter, with respect to the position thereof relative to the reference plane, is closer to the reference plane than the distance point of the receiving section, and
with respect to the position of the blocking section relative to the reference plane, a joint section of the spring arm, which allows the receiving section to pivot counter to a restoring force acting in the direction toward a starting position when the receiving section is pivoted, is closer to the reference plane than the blocking section, wherein pivoting of the receiving section allows a portion of the spring arm located between the blocking section and the distance point to bear against the path limiter, thereby preventing the distance point from being moved along the path limiter in the direction toward the opening.

2. The device according to claim 1 , wherein the spring element comprises a base for supporting the spring element, and wherein:
in relation to the position of the receiving section relative to the base, a blocking section of the spring arm, with respect to which the curved or bent receiving section is designed as a recess, is provided further away from the base than the receiving section,
in relation to the position of the blocking section relative to the base, a joint section of the spring arm, which allows the receiving section to pivot counter to a restoring force acting in the direction toward a starting position when the receiving section is pivoted, is provided further away from the base than the blocking section, and
in relation to the position of the blocking section relative to the base, a stopper section of the spring arm is provided further away from the base than the blocking section.

3. The device according to claim 2 , wherein the receiving section comprises a section that is circular ring segment-shaped or elliptical ring segment-shaped.

4. The device according to claim 2 , wherein the blocking section is arcuate, wherein it is curved opposite to the curved or bent receiving section.

5. The device according to claim 1 , wherein the spring element comprises a base for supporting the spring element, and a receptacle arranged above the base for the head of the component, wherein
a curved or bent receiving section of a spring arm of the spring element is provided as part of the receptacle,
in relation to the position of the receiving section relative to the base, a blocking section of the spring arm, with respect to which the curved or bent receiving section is designed as a recess, is provided further away from the base than the receiving section,
in relation to the position of the blocking section relative to the base, a joint section of the spring arm, which allows the receiving section to pivot counter to a restoring force acting in the direction toward a starting position when the receiving section is pivoted, is provided further away from the base than the blocking section, and
in relation to the position of the blocking section relative to the base, a stopper section of the spring arm is provided further away from the base than the blocking section.

6. The device according to claim 5 , wherein the receiving space is delimited at least by a base surface arranged at the bottom and by a stopper surface which is arranged at the top and faces the base surface, the opening adjoining the stopper surface, the spring element being arranged in the receiving space so as to be supported with the base thereof on the base surface in a starting position and to be supported with the stopper section thereof on the stopper surface, or so that the stopper section is arranged at a distance from the stopper surface but can be brought into contact with the stopper surface when the blocking section is moved in a direction pointing away from the base.

7. The device according to claim 6 , wherein a second stopper surface, which is arranged on the opposite side of the opening with respect to the first stopper surface, the spring element being designed with a second stopper section and a second blocking section, and the spring element being arranged in the receiving space so as to be supported with the second stopper section thereof on the stopper surface in a starting position, or so that the second stopper section is arranged at a distance from the stopper surface but can be brought into contact with the stopper surface when the second blocking section is moved in a direction pointing away from the base, and the second blocking section is arranged beneath the opening.

8. The device according to claim 1 , wherein an abutment is arranged outside the receiving space.

9. A system comprising the device according to claim 1 , and a component including a head, the receiving section of the spring element resting against the head.

10. The system according to claim 9 , wherein an abutment is arranged outside the receiving space of the device, and wherein the component comprises a block, and the block rests against the abutment.

11. A method for pulling out the head, arranged on the component, of the system according to claim 9 , said method comprising
applying a force to the head, the force having at least one component acting in the direction of the reference line;
wherein contact of the head with the curved or bent receiving section causes the receiving section to pivot counter to the restoring force so that the portion of the spring arm located between the blocking section and the distance point bears against the path limiter; and
when the portion of the spring arm located between the blocking section and the distance point bears against the path limiter, elastic or plastic deformation of the spring arm takes place, during which the blocking section is deformed.
