Abstract: The device comprises a casing adapted to be secured, as by gluing, to the sailboard, the casing having a downwardly opening, mortise-defining recess surrounded at its lowermost end by a peripheral flange, the centerboard having a tenon at its upper end adapted to be received in the mortise, the centerboard having a shoulder at its front end adapted to engage the peripheral flange, the tenon terminating rearwardly in an outwardly opening bore having resilient lips adapted to be snap-fitted around a hinge pin extending horizontally between the opposite sides of the mortise, the mortise including a self-locking attachment adjacent its front end releasably engagable with the front end of the tenon to secure the centerboard in the mortise in its normal position of use, the centerboard being readily inserted in and removed from the mortise and pivotable about the hinge pin if it strikes an obstruction.

Abstract: The invention relates to a case of plastics material for an electrical pocket flashlight or pocket lamp energized by battery. It is composed of two bodies, an inner and an outer, assembled together by clipping, the upper body including the parabolic reflector into which a shouldered socket holder ring is adjusted. The metal socket inserted therein has a base provided with a flexible metal strip. In the lower body, slides a cradle supporting the battery and bringing by vertical translation, under the effect of a push-button, the terminals of the battery into contact with the metal strip and the base of the flashlight bulb.
