Abstract: A child resistant roll-and-press lighter includes at least one abutment surface (32; 41; 45) which engages a corresponding counterabutment surface (33; 42; 44) on the lever (20; 50, 51). The surfaces disengage to release the lever for pivotal movement, when and only when at least a predetermined minimum force is applied to the lever pad (23) by the user. The abutment or counterabutment surface may be arranged on a transversely deformable, resilient engaging element (30; 43; 46) which engages the corresponding surface in tension. Alternatively the lever may be mounted in elongate slots so as to translate and so disengage the cooperating surfaces when the minimum force is applied by the user. Alternatively the counterabutment surface may be arranged on a sliding catch (51) housed beneath the lever pad. The minimum force is easily applied by the adult user by rotating the wheel assembly (10) at normal speed.

Abstract: A child resistant piezoelectric gas lighter includes an intermediate member (40, 60, 70, 80) and a safety button (50) which is operable to set the intermediate member from a disabled condition, wherein the trigger (30) is depressible without actuating the piezoelectric spark generator (20) or, less preferably, thee valve, to an enabled condition wherein the intermediate member transmits the actuating motion from the trigger to the piezoelectric device to generate a spark, and operate the lighter. The intermediate member may be a resilient leaf (40, 60) mounted at a fixed point on the trigger (30) or piezoelectric device (20) or may be a separate element (70) mounted on the lighter body (1) for translational movement and engaging both components.

Abstract: A roll and press gas lighter is rendered child resistant by an impeding element (26) mounted on the lighter body such that its surface (26?) is preferably substantially flush with a low friction surface (16?) which forms the outer periphery of the thumbwheels (16). The impeding element preferably comprises a protective strip which extends around the sparkwheel (15). In use the engaging surface (26?) of the impeding element is engaged by the user's thumb simultaneously with the low friction surface, increasing the force required to rotate the sparkwheel and hence the child resistance of the lighter. The degree of child resistance of the lighter is determined inter alia by the smoothness of the thumbwheels and the position of the impeding element.

Abstract: A roll and press gas lighter is rendered child resistant by an impeding element (26) mounted on the lighter body such that its surface (26′) is preferably substantially flush with a low friction surface (16′) which forms the outer periphery of the thumbwheels (16). The impeding element preferably comprises a protective strip which extends around the sparkwheel (15). In use the engaging surface (26′) of the impeding element is engaged by the user's thumb simultaneously with the low friction surface, increasing the force required to rotate the sparkwheel and hence the child resistance of the lighter.

Abstract: A roll and press gas lighter is rendered child resistant by a protective strip (26, 35) which extends around the sparkwheel (15) and impedes the action of the user's thumb. The wheel assembly (13) is mounted for reciprocal motion and upwardly biased by the flint spring (19), and is depressed by the user during operation. The thumbwheel (16) may have a smooth periphery to increase the force required to rotate it.

Abstract: The invention relates to a roll and press lighter which is rendered child resistant by a fixed extension of the body which surrounds or bisects the lever so as to impede the user's thumb. The adult user must operate the lighter in such a way that the flesh of the user's thumb is able to depress the lever below the level of the fixed extension.

Abstract: The invention relates to a roll and press gas lighter which is rendered child resistant by frictionally retarding the wheel assembly, making it difficult for a child to rotate it. The wheel assembly may have a serrated axle rotating in a serrated bearing; the periphery or sides of the thumbwheel may have projections which engage with the lever or lighter body. The wheel assembly may be formed in two parts, urged apart by an internal spring so as to frictionally engage in frustoconical bearings; alternatively the wheel assembly may rotate frictionally around a fixed axle. The wheel assembly may be retarded by a rubber wheel or a fixed leaf spring. Alternatively the flint may be provided with a strong spring to retard the sparkwheel, and the sparkwheel may he indented to engage with the flint.
