Abstract

An in-line roller skate having a boot fixed releasably to a chassis. The fastening device uses the toggle effect and comprises a latch which is articulated to the chassis and has a point which interacts with a housing on the boot. This latch is kept engaged by the blocking of a toggle joint which can be actuated by means of a lateral lever. The boot is fixed at an opposite position (A) by a hook.

The latch may be in the form of a pedal actuable by the boot.

Claims

1. A roller skate comprising a chassis (1) consisting of at least one part equipped with rollers (2, 3, 4, 5) and a boot (6) fixed releasably to this chassis by fastening means which secure the boot to the chassis, at a first location (A) by hooking effected by the mutual longitudinal engagement of a part of the boot (9) and a part of the chassis (7), and at a second location (B) by a toggle-effect fastening device, wherein the toggle-effect fastening device is located in the chassis under the boot and comprises a latch (11;

23;

     35) which is articulated to the chassis about a transverse pin and has a pointed end (11a;

23a;

35a) that interacts with a housing on the boot, this latch being capable of occupying two stable positions, namely an obliquely raised position in which its point is out of the housing on the boot, and a lowered position in which its point is engaged in the housing on the boot, in the opposite direction to the engagement at the first hooking location, and kept engaged by the blocking of the toggle joint by exerting, a vertical pressure and a longitudinal thrust in the opposite direction.

2. The skate as claimed in claim 1, wherein the latch (11) is furthermore articulated to the end of a pair of toggle-articulated bars (14, 16).

3. The skate as claimed in claim 2, which comprises a lever (19) linked in rotation with one of the bars of the toggle joint for actuating the toggle joint in order to bring it into a blocking position.

4. The skate as claimed in claim 1, wherein the latch is in the form of a pedal (23;

35) which is lowered by pressure of the boot.

5. The skate as claimed in claim 4, wherein the pedal (23) is articulated to the end of a pair of toggle-articulated bars (26, 27) and it comprises a lever (28) linked in rotation with the toggle joint for actuating the toggle joint in order to bring it into a blocking position.

6. The skate as claimed in claim 4, wherein the pedal (35) has a second point (35b), located under the first point (35a) and forming an acute angle with this first point, and it constitutes one of the arms of the toggle joint, the other arm (38) being elastically compressible axially so that the toggle effect is obtained automatically when the pedal is lowered.

7. The skate as claimed in claim 6, which comprises auxiliary means (44;

58) for locking the pedal.

8. The skate as claimed in claim 7, wherein the auxiliary locking means consist of a latch (44) which slides in the chassis and locks the second point (35b) of the pedal.

9. The skate as claimed in claim 7, wherein the locking means consist of a sliding latch (44) mounted at the end of an auxiliary toggle joint (53, 55a).

10. The skate as claimed in claim 7, wherein the locking means consist of a latch (58) which slides on the chassis and engages under the articulation (43) of the toggle joint.

11. The skate as claimed in claim 8, wherein the sliding latch (44) engages between the points (35a, 35b) of the pedal, and it is secured to a manually actuable lever (62).

12. The skate as claimed in claim 11, wherein the lower side of the second point (35b) of the pedal has a ramp which can push away the sliding latch (44) when the pedal descends, and the sliding latch is pushed in the direction of the pedal by a spring, so that locking is obtained automatically when the pedal is lowered.

13. The skate as claimed in claim 1, characterized in that the hooking at the first location (A) has at least one ramp which presses the boot against the skate.

14. The skate as claimed in claim 1, wherein the two fastening locations are in the heel region, and the skate and the boot have longitudinal guide means (31, 32) in front of the heel.

15. The skate as claimed in claim 1, wherein, at at least one of the two securing locations, the fastening means have means (10;

25;

     41) for centering the boot on the skate.
