Abstract

The invention relates to a pulling device (16) for a trailer (10) for a user to pull the trailer (10), in particular a cross-country skier. The pulling device (16) has a first rod element (20), a second rod element (22) and a spring device (24). The first rod element (20) is mounted on the second rod element (22) in an axially movable and spring-loaded manner. In addition, the pulling device (16) has a locking device (40) which can move between a locking state in which the first rod element (20) is axially fixed to the second rod element (22), and a release state. The invention also relates to a trailer (10) comprising a pulling device (16).(Fig-4)

Claims (13)

Claims
1. A pulling device (16) for a trailer (10) for a user to pull the trailer (10), in particular a cross-country skier, wherein the pulling device (16) has a spring device (24), and wherein the pulling device (16) has a locking device (40) which can move between a locking state in which the spring device (24) is blocked and a release state.
2. The pulling device (16) according to claim 1, wherein the pulling device (16) has a first rod element (20) and a second rod element (22), wherein the first rod element (20) is mounted on the second rod element (22) in an axially movable and spring-loaded manner by means of the spring device (24), wherein the locking device (40) is designed to axially fix the first rod element (20) to the second rod element (22) in the locking state.
3. The pulling device (16) according to claim 2, wherein the locking device (40) has a locking element (42) which is held on the second rod element (22) so as to be movable between a locking position in which the locking element (42) engages with the first rod element (20) and a release position, in particular wherein the locking element (42) is movable in a direction that is transverse to an axial direction of the first rod element (20).
4. The pulling device (16) according to claim 2 or 3, wherein the locking device (40) has a retaining element (44) by means of which the locking element (42) is held on the second rod element (22) so as to be axially fixed in position.
5. The pulling device (16) according to claim 3 or 4, wherein the locking device (40) is configured to provide a first latched position for the locking element (42) when in its locking position, and/or to provide a second latched position for the locking element (42) when in its release position.
6. The pulling device (16) according to any one of the preceding claims 2 to 5, wherein the Iocking device (40) has a damping element which engages with the first rod in the Iocking position, in particular wherein the damping element is held on a side of the Iocking element (42) that faces the first rod element (20), and/or in particular wherein the Iocking element (42) only engages with the first rod element (20) in the Iocking position by means of the damping element.
7. The pulling device (16) according to any one of claims 3 to 6, wherein the retaining element (44) forms a guide (46) for the Iocking element (42), in particular wherein an actuating side of the Iocking element (42) is aligned with the guide (46) so as to be flush therewith in the Iocking position, and/or in particular wherein an actuating side of the Iocking element (42) is aligned with the guide (46) so as to be flush therewith in the release position.
8. The pulling device (16) according to any one of claims 3 to 7, wherein the Iocking element (42) is made up of two parts, in particular which are connected to one another by a snap-fit connection and/or which collectively envelope the second rod element (22) and/or the retaining element (44).
9. The pulling device (16) according to any one of claims 4 to 8, wherein the retaining element (44) is made up of tvvo parts, in particular which are connected to one another by a snap-fit connection and/or which collectively envelope the second rod element (22).
10. The pulling device (16) according to any one of the preceding claims 2 to 9, wherein the Iocking device (40) is held at a through-opening (52) of the second rod element (22), in particular by the Iocking element (42) protruding at least partially into the through-opening (52) of the second rod element (22) both in the engagement position and in the release position, and/or in particular by the retaining element (44) having a projection (54) which projects into the through-opening (52) of the second rod element (22).
11. The pulling device (16) according to any one of the preceding claims 2 to 10, wherein the first rod element (20) is held on the second rod element (22) so as to rotate about its axial extent, and wherein the first rod element (20) is also held on the second rod element (22) so as to be further rotatable about its axial extent when the locking device (40) is in its locking state.
12. The pulling device (16) according to any one of claims 4 to 11, wherein the locking device (40) is sealed, in particular sealed against snow, in particular by the through-opening (52) in the second rod element (22) being sealed, and/or in particular by a space between the retaining element (44) and the locking element (42).
13. Atrailer (10) having a pulling device (16) according to any one of the preceding claims, wherein the trailer (10) is designed to be pulled by a user, in particular a cross-country skier, by means of the pulling device (16).
