Abstract

A band lock (1) comprising a first (2) and a second (3) part, which each comprises partly engagement portions (4, 5) for mutual detachable coupling with each other, partly band coupling portions (8, 9) for cooperation with a band (20, 21) each. The engagement portion (4) of the first part (2) comprises an engagement pin (6) extended in the transversal direction (T), and the engagement portion (5) of the second part (3) comprises a hook element (7), which delimits a seat (S) for the engagement pin (6) which seat extends essentially in a transversal direction (T). With the engagement pin (6) placed in the seat (S), a rotational joint is formed with a rotational axis (A) extending in said transversal direction (T) for allowance of the parts (2, 3) to be restrictedly rotatable in relation to each other around the rotational axis (A). The invention also relates to a child carrying device.

Claims

1. Band lock (1) comprising a first (2) and a second (3) part, which each comprises partly engagement portions (4, 5) at respective first ends for mutual detachable coupling with each other, partly band coupling portions (8, 9) at respective second ends for cooperation with a band (20, 21) each, wherein the first (2) and the second (3) part forms a respective transversal direction (T) in right angle to an intended longitudinal extension (B) for and essentially parallel to a transversal extension for a band intended for cooperation, characterized in that

the engagement portion (4) of the first part (2) comprises an engagement pin (6) extending essentially in said transversal direction,

the engagement portion (5) of the second part (3) comprises a hook element (7) which delimits a seat (S) for the engagement pin (6), which seat extends essentially in said transversal direction (T),

a resilient lock element (11) is arranged at the seat (S) for acting against an engagement pin (6) inserted in the seat, and

with the engagement pin (6) placed in the seat (S), a rotational joint is formed, with a rotational axis (A) extending in said transversal direction (T), for allowing the first part (2) and the second part (3) to be limitedly rotatable in relation to each other around the rotational axis (A).

2. Band lock according to claim 1, characterized in that the engagement pin (6) is at least partially circularly cylindrical.

3. Band lock according to claim 2, characterized in that the seat (S) is complementary designed to the engagement pin (6) and likewise at least partially circularly cylindrical.

4. Band lock according to claim 1, characterized in that the hook element (7) is an element which extends in said transversal direction (T), is bent around, and tapers off in said transversal direction (T) towards a free end (7′

).

5. Band lock according to claim 1, characterized in that said lock element (11) is arranged on a free end (7′

) of a tongue formed element.

6. Band lock according to claim 1, characterized in that each one of the first (2) and the second (3) part comprises a frame of plastic material, wherein each frame integrally comprises an engagement portion (4, 5) as well as a band coupling portion (8, 9).

7. Band lock according to claim 1, characterized in that at least one of the first (2) and the second (3) part exhibits a transversal fixed rod and side edges with guide lists (14, 15, 16, 17), which carries a movable lock member (18, 19) for locking cooperation with said band (20, 21) between the lock member (18, 19) and the fixed rod.

8. Band lock according to claim 1, characterized in that at least one of the first (2) and the second (3) part exhibits a transversal fixed rod (35, 36) and side edges with lists (14, 15, 16, 17), and comprises a rotatable lock member (33, 34), for locking cooperation with said band (20, 21), said rotatable lock member (33, 34) being arranged between the lists (14, 15) rotatable around a rotational axis (37, 38) being essentially parallel to the transversal direction, which rotatable lock member (33, 34) has an engagement portion (39, 40) with an essentially constant cross section along the rotational axis (37, 38) and with an engagement surface (41, 42) to be in engagement with a band (20, 21), which engagement portion (39, 40) exhibits a distance between the rotational axis (37, 38) and the engagement surface (41, 42) which varies around the rotational axis (37, 38).

9. Band lock (1) according to claim 8, characterized in that the engagement portion (39, 40) is essentially symmetrical around a symmetry axis (43, 44) arranged parallel to the rotational axis (37, 38) at a distance from the rotational axis (37, 38).

10. Band lock (1) according to claim 9, characterized in that the engagement portion (39, 40) of the rotatable lock member (33, 34) is essentially circularly cylindrical around the symmetry axis (43, 44).

11. Band lock (1) according to claim 8, characterized in that it is arranged with restricting means (45, 46) restricting the rotational movement of the rotatable lock member (33, 34), wherein the surface of the band lock that is arranged to be in contact with the body of a user essentially defines a first plane (47), wherein the rotational axis (37, 38) is in a second plane (48) being parallel to the first plane (47) and wherein the engagement portion (39, 40) is restricted by the restricting means to have a major part of its volume between the first plane (47) and the second plane.

12. Band lock according to claim 1, characterized in that the first part (2) exhibits a transversal list (22), which is parallel to the engagement pin (6) and situated at a distance (a) from this which essentially corresponds to the dimension of the hook element (7), seen between a free end (7′

) thereof and an outer point (23) on the engagement portion (5) of the second part (3).

13. Band lock according to claim 1, characterized in that the second part (5) is provided with an insertion opening (29) for the engagement pin (6) to the seat (S) directed essentially perpendicularly to said intended longitudinal extension (B) for a band intended for cooperation and essentially perpendicularly to said transversal direction (T).

14. Child carrying device including a child harness, upper carrying straps and a waist band, characterized in that it is provided with a band lock according to claim 1.
