The present invention relates to the field of portable lamps and more specifically to a universal adaptor bracket for removable portable lamp
The use of portable lamps tends to become widespread in all human activities, whether professional, sports or leisure activities.
Historically, construction or miners' helmets, such as those illustrated in
Today, as seen in
There is a wish to develop the possibilities of fixing a portable lamp on various supports or accessories and, consequently, to be able to count on a universal adaptor bracket allowing the fixing of a wide range of removable portable lamps.
This is the subject of this patent application.
It is an object of the present invention to provide a universal adaptor bracket allowing a secure fixing system for a removable portable lamp, without risk of accidental fall.
It is another object of the present invention to allow a universal adaptor bracket which allows a compact fixing system with a removable portable lamp of variable dimensions.
It is a third purpose of this invention to provide an architecture of adaptor brackets that can be designed in several versions: safety helmet, bicycle, or any support whatsoever.
The present invention makes it possible to achieve all these objects by producing an adaptor bracket for a removable portable lamp comprising a base or a frame comprising a first supporting lug and a second supporting lug.
The first supporting lug has, on its upper face, a first groove of substantially circular profile, configured to allow engagement of a first substantially circular rib of a removable portable lamp having a first dimension. Similarly, the second supporting lug has, on its underside, a second substantially circular profile groove, configured to allow engagement of a second substantially circular profile rib of said removable portable lamp. Furthermore, the adaptor bracket comprises a locking system based on a stop or a locking clip intended to block the engagement of said first and second ribs at a predetermined position in the first and second grooves.
In a particular embodiment, the base comprises a tongue or locking clip comprising a stud which is positioned in the middle of the first groove corresponding to the first supporting lug. The tongue has sufficient flexibility to allow elastic deformation so that when the first rib of the lamp—having a notch in its middle—is engaged in the corresponding groove of the first supporting lug, a stress is applied to the supporting lug or locking clip so as to flex the latter in order to allow said first rib to slide until the notch is positioned under the stud of the supporting lug or locking clip so as to block the positioning of the lamp.
Preferably, the adaptor bracket comprises a third supporting lug located above the second supporting lug and the third supporting lug comprises, on its lower face, a third groove of substantially circular profile configured to allow engagement of a second rib of substantially circular profile d a portable lamp having a second larger dimension.
Preferably, 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.
In a particular embodiment, the adaptor bracket is a bicycle adaptor bracket.
In another embodiment, the adaptor bracket is a adaptor bracket for a safety helmet having a rear tongue configured to be inserted into a corresponding slot in the front of a safety helmet to allow attachment of a light portable removable on the construction helmet. The tongue is made of an elastic material allowing, when inserting the tongue into the slot of the helmet, to exert a pressure pushing the adaptor bracket towards the safety helmet. Optionally, the rear tongue has a circular recess intended to receive a self-adhesive circular pad or patch allowing secure attachment of the adaptor bracket to the hard hat.
In another embodiment, the adaptor bracket comprises at the rear 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.
Other features of one or more embodiments of the invention will appear from the following description of embodiments of the invention, with reference being made to the accompanying drawings.
We now describe a general structure of a universal adaptor bracket allowing a compact fixing for a wide range of removable portable lamps or more generally any useful accessory.
This general structure can be broken down into different embodiments, as illustrated in
Indeed,
Finally,
The adaptor bracket of
Thanks to such system, the user may very easily mate or slide the two parts together and facilitate removable attachment of the accessory to the adaptor bracket and thus the safety helmet. The sliding of the two parts is based on a circular moving thanks to the circular profiles of both the grooves on the rail projection arrangement and the ribs, thus complying with the particular geometry of a safety helmet.
For that purpose, adaptor bracket comprises 100 comprises a first lower horizontal supporting lug 110, a second upper horizontal supporting lug 120 and, optionally , a third upper horizontal supporting lug 130 located above the second supporting lug.
All supporting lugs 110, 120 and optionally 130 are integral with the adaptor bracket 100 and carry out a projection arrangement with respect to the adaptor bracket, realizing at least one and preferably two rail systems for the circular moving and attachment of an portable lamp or accessory. More particularly, each supporting lug 110, 120 and optionally 130 has a respective circular groove which is configured to cooperate and mate the circular profiles of ribs 11 and 12 of a removable portable lamp or accessory part to be removably attached to the helmet.
Thus, the connection between the removable portable lamp to be guided and attached to the adaptor bracket and the guide adaptor bracket is ensured by the engagement of two dedicated circular ribs 11 and 12 in
As seen in
In one embodiment, the circular profile of the supporting lugs 110, 120 and optionally 130 corresponds to a circular profile having a radius of curvature comprised in a range equal to 100-200 mm. Preferably the radius of curvature is fixed at 150 mm.
As can be seen in
By sliding the lamp 10 into the two circular grooves of the supporting lugs 110 and 130, it is thus possible to create a solid and secure connection between the lamp 10 and the adaptor bracket 100.
In a particular embodiment, there is also a stop or locking mechanism, preferably located on the lower supporting lug 110.
Preferably, there is a tongue or locking clip 105 integral with the base or the frame of bracket 100 and having sufficient flexibility to allow elastic deformation. The tongue or locking clip 105 has at its end a protrusion or stud which is positioned in the middle of the groove corresponding to the first supporting lug 110. The rib 11 of the lamp 10 has in its middle a notch configured to cooperate with the locking clip 105 so that when the rib 11 is engaged in the curved groove of the supporting lug 110, a stress is applied to the flexible material of the tongue 105 which flexes to allow the sliding of the rib 11 in the tongue until the notch 15 is positioned at the level of the nipple of the tongue or flexible clip allowing the latter to return to its rest position, thus achieving secure blocking and locking of the lamp 10.
Of course, the locking system could be arranged on one side of the rib in another embodiment. Any other stop and abutment system may be considered.
It will be noted in this illustrative example that the lamp 10, of large size, has two different lower rib 11 and upper rib 12 since only the rib 11 has a notch 15. This asymmetry within the lamp 10, associated with the configuration of the adaptor bracket 100 makes it possible to achieve keying ensuring that the user will always position the lamp 10 in the right direction, that is to say with a control button 19 located at the top of the lamp 10.
Finally,
Lamp 20 corresponds to a small “sports” type lamp which, in a preferred embodiment, also includes a notch 25 similar to notch 15 of lamp 10, as shown in
3G, 4H and 4I illustrate a rapprochement of the removable lamp 20 and the engagement of its ribs 21 and 22 in the grooves associated with supporting lugs 110 and 120, until the complete engagement of the ribs and to the locking of the lamp 20 with the locking clip 105.
Will now be described in relation to
As before, the ribs 31 and 32 are configured to engage in the corresponding grooves of the supporting lugs 110 and 130 and therefore have a circular profile with a radius of curvature between 100 mm and 200 mm.
Thanks to this double notch 35-36, the lamp 30 can be fixed on the adaptor bracket 100—or any other adaptor bracket illustrated in particular in the
In this arrangement, the removable lamp 30 is positioned according to a first configuration with the control button 39 located at the top . . .
In this arrangement, the removable lamp 30 is positioned according to a first configuration with the control button 39 located at the top . . .
In this arrangement, the removable lamp 30 is positioned in a second configuration with the control button 39 located at the bottom.
This second configuration can be very advantageous in certain circumstances, for example when the removable lamp is mounted on a safety helmet on which there are other accessories that may interfere with the use of a control button located on the top.
Alternatively, the user could also prefer to control the removable lamp with his thumb, which will also lead him to favor this second configuration and, consequently, the cooperation of the notch 36 with the locking clip 105.
As can be seen, the proposed universal adaptor bracket has vast configuration possibilities, with the fixing of lamps of various sizes and also has great compactness due to the curvature of the fixing lugs allowing a removable lamp to be held at most near a construction helmet.
