Abstract

A adaptor bracket for a wide range of removable portable lamps intended to be fixed on various supports or accessories. The bracket has a base or frame having a first supporting lug with a circular groove to engage a first rib and has a second supporting lug with a circular groove to allow engagement of a second rib. The adaptor bracket has a locking system based on a stopper or locking clip intended to block the engagement of the first and second ribs at a predetermined position.

First claim

What is claimed is:

1. An adaptor bracket for a removable portable lamp intended to be fixed on a support and comprising:
a base or frame having a first supporting lug and a second supporting lug;
wherein the first supporting lug has, on its upper face, a first groove of substantially circular profile, wherein said circular profile is configured to correspond to the circular shape of a helmet, wherein said first supporting leg is configured to allow engagement of a first substantially circular rib of a removable portable lamp having a first dimension;
wherein the second supporting lug has, on its underside, a second groove of substantially circular profile, configured to allow engagement of a second rib of substantially circular profile of said removable portable lamp;
wherein the adaptor bracket comprises a locking system based on a stopper or a locking clip intended to block the engagement of said first and second ribs at a predetermined position
wherein the grooves corresponding to said first and said second supporting lugs have a radius of curvature within a range equal to 100-200 mm, and preferably equal to 150 mm.

2. The adaptor bracket for a removable portable lamp as defined in claim 1 wherein said base or said frame comprises locking clip comprising a stud which is positioned in the middle of the first groove corresponding to said first supporting lug, said tongue having sufficient flexibility to allow elastic deformation, so that when the first rib of said removable portable lamp is engaged in the corresponding groove of said first supporting lug,
wherein the first rib has a notch in its middle configured to cooperate with said locking clip, a stress is printed on said locking clip so as to flex the latter in order to allow the sliding of said first rib until said notch is positioned under said tab or locking clip so as to block the positioning of said removable portable lamp.

3. The adaptor bracket according to claim 2 , further comprising a third supporting lug located above the second supporting lug; wherein the third supporting lug has, on its underside, a third groove of substantially circular profile configured to allow engagement of a second rib of substantially circular profile of a portable lamp having a second dimension, wherein the second dimension is greater than the first dimension.

4. The adaptor bracket according to claim 1 , wherein the grooves corresponding to said first, second and third circular supporting lugs have a radius of curvature within a range equal to 100-200 mm, and preferably equal to 150 mm.

5. The adaptor bracket according to claim 1 wherein the adaptor bracket is a bicycle adaptor bracket.

6. The adaptor bracket according to claim 1 wherein the adaptor bracket is an adaptor bracket for a safety helmet comprising a rear tongue configured to be inserted into a corresponding slot located at the front of a safety helmet so as to allow the fixing of a removable portable lamp on said safety helmet; wherein the tongue is made of an elastic material allowing, when inserting the tongue into the slot of the helmet, to print a bias of the adaptor bracket towards the safety helmet.

7. The adaptor bracket according to claim 6 wherein said rear tongue has a circular recess intended to receive a self-adhesive circular patch or patch allowing secure attachment of the adaptor bracket to the hard hat.

8. The adaptor bracket according to claim 1 wherein the adaptor bracket comprises four fixing lugs each provided with a self-adhesive adhesive so as to allow the fixing of the adaptor bracket on a substantially flat support.

9. A headlamp comprising a first circular rib and a second circular rib configured to slide into the corresponding groove of said first supporting lugs or one of said second or third supporting lug of the adaptor bracket of claim 1 .

10. An adaptor bracket for a removable portable lamp intended to be fixed on a support and comprising;
a base having a first supporting lug and a second supporting lug;
wherein the first supporting lug has, on its upper face, a first circular groove configured to allow engagement of a first circular rib of a removable portable lamp or accessory having a first dimension;
wherein the second supporting lug has, on its underside, a second circular groove configured to allow engagement of a second circular rib of said removable portable lamp or accessory;
wherein said first circular rib is located at the bottom of the portable lamp or accessory;
wherein said second circular rib is located at the top of said portable lamp or accessory; and
wherein both circular grooves and circular ribs are configured to easily mate and slide the parts together in a circular movement, so as to facilitate removable attachment of the portable lamp or accessory to the adaptor bracket, and
wherein the grooves corresponding to said first and said second supporting lugs have a radius of curvature within a range equal to 100-200 mm, and preferably equal to 150 mm.

11. The adaptor bracket according to claim 10 characterized in that the adaptor bracket comprises a locking system based on a stopper or a locking clip intended to block the engagement of said first and second ribs at a predetermined position,
in order to allow the attachment of a portable lamp or any other useful movable accessory, accessory bracket is additionally fitted with a new specific circular groove projection arrangement that is configured to mate with two corresponding circular ribs of a corresponding movable accessory.

12. The adaptor bracket as defined in claim 10 wherein said adaptor bracket is configured to be affixed on a safety helmet.

13. The adaptor bracket according to claim 10 , further comprising a third supporting lug located above the second supporting lug; wherein the third supporting lug has, on its underside, a third groove of substantially circular profile configured to allow engagement of a second rib of substantially circular profile of a portable lamp having a second dimension, wherein the second dimension is greater than the first dimension.

14. The adaptor bracket according to claim 10 , wherein the grooves corresponding to said first, second and third circular supporting lugs have a radius of curvature within a range equal to 100-200 mm, and preferably equal to 150 mm.

15. The adaptor bracket according to claim 10 wherein the adaptor bracket is a bicycle adaptor bracket.
