Description

SPECIFICATION Battery-operated hazard warning lamps This invention relates to battery-operated hazard warning lamps of the kind comprising a casing in which one or more than one electric cell can be housed, at least one lens mounted in a wall of or mounted on the casing and, housed within the casing, a holding unit carrying a bulb or other light emitting device which can be electrically connected to the cell or cells and which is positioned behind the or each lens. A battery-operated hazard warning lamp of this kind will, for convenience, hereinafter be referred to as "of the kind described".
It has been proposed to provide, for warning traffic and pedestrians of an excavation in the road or pavement or of other roadworks or obstructions, an upstanding post which, at its upper end, incorporates a battery-operated hazard warning lamp. Upstanding posts incorporating battery-operated hazard warning lamps have the disadvantage that one or both of the post and lamp has or have to be specially designed and, as a consequence, an upstanding post incorporating a battery-operated hazard warning lamp is unnecessarily expensive.
It is an object of the present invention to provide a cradle which is adapted to support a battery-operated hazard warning lamp of the kind described and usually employed free standing on the ground and which can be mounted on the upper end of an upstanding post of the kind conventionally used in road hazard barriers.
According to the invention, we provide, for use in supporting on the upper end of an upstanding post a battery-operated hazard warning lamp of the kind described, a cradle which is separately formed with respect to the lamp and which comprises a base, a wall or walls upstanding from the base and defining an enclosure in which the hazard warning lamp can be retained, the wall or walls being of such a shape and form that the or each lens of the lamp is exposed, and, dependent from the base, means for mounting the cradle on and securing the cradle to the upper end of the upstanding post.
The base preferably extends across the whole of the transverse cross-section of the cradle but, in some circumstances, it may comprise a peripheral continuous or discontinuous ledge at the foot of the wall or walls.
For reception of a battery-operated hazard warning lamp of the kind described having a casing of substantially rectangular transverse cross-section with a lens in each of its oppositely disposed major side walls, the cradle preferably comprises a base of substantially rectangular shape, a pair of oppositely disposed minor side walls upstanding from and extending along oppositely disposed shorter sides of the base and, upstanding from and extending along one longer side of the base between said minor side walls, a single major side wall in which there is a hole or recess through which one of the lenses of the lamp will be exposed.
Preferably, the cradle includes means for so securing a battery-operated hazard warning lamp of the kind described when supported within the enclosure to the wall or walls of the cradle that the lamp is movable with respect to the cradle to such an extent that an electric cell or electric cells of the lamp can be replaced and/or the operating switch of the lamp can be actuated without detaching the lamp from the cradle.Where the lamp has a casing of substantially rectangular transverse cross-secticn, preferably the upstanding minor side walls of the cradle have means for so connecting the cradle to the oppositely disposed minor side walls of the rectangular casing of a lamp that the lamp is pivotable with respect to the cradle, about an axis extending transversely of the cradle, through the open side of the cradle to facilitate access to the electric cell or electric cells and to the operating switch of the lamp.Where the cradle has means for pivotally mounting a lamp within the cradle, the cradle may also include means for restraining a lamp against such pivotal movement; such restraining means may comprise a leaf spring which must be deflected to permit such pivotal movement or means for effecting a snap engagement with the lamp and past which the lamp must be forced to permit such pivotal movement.Alternatively, or additionally, where the lamp casing has a bolt for mounting the lamp on a support and/or for securing two parts of the lamp casing together and/or for retaining an electric cell or electric cells within the lamp casing, the upstanding wall or an upstanding wall of the cradle may have an aperture through which the bolt of a lamp can be passed to secure the lamp to the cradle; in this case, this bolt will have to be removed before pivotal movement of the lamp with respect to the cradle can occur.
The means for mounting the cradle on and securing the cradle to the upper end of an upstanding post preferably comprises a downwardly extending tubular boss which will fit over and effect a snap-fit engagement with the upper end of an upstanding post. The snap-fit engagement preferably is of sufficient strength to prevent unauthorised removal of the cradle from the post upon the application of manual effort without effecting damage to the cradle and/or post. In a preferred embodiment, the downwardly extending tubular boss has on its inner surface at least one peripherally continuous or discontinuous rib which will effect a snap-fit engagement in a peripherally continuous or discontinuous groove in the outer surface of the upper end of an upstanding post.
Where an upstanding post has an external transverse cross-section of substantially circular form, the snap-fit engagement between the downwardly extending tubular boss of the cradle and the upstanding post may be such that the cradle can be rotated about the axis of and with respect to the post but, preferably, the tubular boss can be so keyed to the post or can be otherwise so secured to the post that relative rotational movement between the cradle and the post is prevented.
To provide for the case where a lamp to be supported in the cradle has an operating switch which is actuated through a hole in the wall of the lamp casing, preferably the upstanding wall or walls of the cradle has or have a hole or holes therethrough which will be in alignment with a hole or holes in a lamp casing and will provide access to the operating switch when the lamp is supported in the cradle, so that the operating switch can be actuated using an elongate tool of appropriate length without removing the lamp from or moving the lamp with respect to the cradle.
The cradle may have at least one pair of oppositely disposed means for detachable connection of a flexible tape or rope. Such tape connection means preferably each comprise a resilient finger which, at one of its ends, is integral with the or an upstanding wall of the cradle and which, at the other of its ends, bears against said wall to provide for ready introduction of a flexible tape or rope between the wall and said finger.
Preferably, the cradle is a single moulded body of plastics material, preferably yellow in colour. The upstanding wall or at least one of the upstanding walls of the cradle may have on its outer surface at least one strip of light reflecting material.
The invention also includes an improved battery-operated hazard warning lamp and cradle assembly for mounting on the upper end of an upstanding post, which assembly comprises a cradle comprising a base, a wall or walls upstanding from the base and defining an enclosure and, dependent from the base, means for mounting the cradle on and securing the cradle to the upper end of an upstanding post; and a battery-operated hazard warning lamp of the kind described supported on the base within the enclosure and so permanently secured to the cradle that the lamp is movable with respect to the cradle to such an extent that an electric cell or electric cells of the lamp can be replaced and/or the operating switch of the lamp can be actuated without detaching the lamp from the cradle, the wall or walls defining the enclosure being of such a shape and form that the or each lens of the lamp is exposed.
Where the road hazard warning lamp of the kind described has a casing of substantially rectangular transverse cross-section, the cradle preferably has a base of substantially rectangular shape, a pair of oppositely disposed minor side walls upstanding from and extending along oppositely disposed shorter sides of the base and, and upstanding from and extending along one longer side of the base between said minor side walls, a single major side wall in which there is a hole or recess through which one of the lenses of the lamp is exposed, the minor side walls of the lamp being permanently pivotally connected between the minor side walls of the cradle sc that the lamp can be pivoted with respect to the cradle through the open side of the cradle to facilitate replacement of an electric cell or electric cells of the lamp and/or actuation of the operating switch of the lamp.
The cradle of the battery-operated hazard warning lamp and cradle assembly of the invention may have any one or more of the features of the cradle hereinbefore described.
The invention further includes an improved hazard warning device comprising a post upstanding from a base and, permanently secured to the upper end of the upstanding post, an improved battery-operated hazard warning lamp and cradle assembly as hereinbefore described.
By virtue of the fact that, in the improved hazard warning device as hereinbefore described, the lamp is permanently secured to the cradle and the lamp and cradle assembly is permanently secured to the post, the risk of unauthorised removal of or tampering with the lamp is substantially reduced.
The invention is further illustrated by a description, by way of example, of a preferred cradle for supporting a battery-operated rcad hazard warning lamp of the kind described having a casing of substantially rectangular transverse cross-section and of a preferred battery-operated road hazard warning lamp and cradle assembly, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of the preferred cradle; Figures 2 and 3, respectively, are a front view and a sectional side view of the cradle, and Figure 4 is a perspective view of the road hazard warning lamp and cradle assembly.
Referring to Figures 1 to 3, the preferred cradle is made of moulded yellow plastics material and comprises a base 1 of rectangular shape, a pair of oppositely disposed minor side wails 2 upstanding from and extending along oppositely disposed shorter sides of the base and, upstanding from and extending along one longer side of the base between the minor side walls, a single major side wall 3 which has in its upper edge a recess 4 of arcuate shape. Depending downwardly from the undersurface of the base 1 is a tubular boss 5 of circular cross-section having on its inner surface a peripherally continuous rib 6 which, when the tubular boss is fitted over an upstanding post of circular cross-section, will effect a snap-fit engagement in a peripherally continuous groove in the outer surface of the upper end of the post.Each of the minor side walls 2 has on its outer surface a vertical strengthening rib 7 which is integral with a strengthening rib 8 on the undersurface of the base 1 and also has on its outer surface horizontal strengthening ribs 9. To provide for detachable connection of a flexible tape or rope to the cradle, the vertical strengthening rib 7 of each minor side wall 2 has integral with its lowermost end an upstanding resilient finger 10 which, at its free upper end, bears against the wall to provide for ready introduction of a flexible tape or rope between the wall and the finger.
At the upper end of each of the minor side walls 2 is an inwardly extending tubular boss 11 which, when a battery-operated road hazard warning lamp having a casing of rectangular transverse cross-section is mounted in the cradle, will be in axial alignment with holes in the minor side walls of the lamp casing and through which pivot pins (not shown) will engage with the holes in the minor side walls of the lamp casing so that the lamp is pivotable with respect to the cradle, about an axis extending transversely of the cradle, through the open side of the cradle to facilitate access to the electric cells of the lamp. A leaf spring 12 on the upper surface of the base 1 serves to restrain a lamp, when supported in the cradle, against such pivotal movement.When it is required to replace an electric cell ofa lamp supported in the cradle, the leaf spring 12 must be deflected to permit pivotal movement of the lamp with respect to the cradle through the open side of the cradle.
To accommodate a battery-operated road hazard warning lamp having a casing of rectangular transverse cross-section and having, within the lamp casing, a slidable operating switch which is actuated by an elongate tool through holes in the minor side walls of the lamp casing, each of the minor side walls 2 of the cradle has an aperture 14 which will be in axial alignment with a hole in a minor side wall of a lamp casing through which actuation of the slidable operating switch of the lamp can be effected.
Where the casing of a battery operated road hazard warning lamp has a bolt for mounting the lamp on a support and/or for securing two parts of the lamp casing together and/for retaining an electric cell or electric cells within the lamp casing, the major side face 3 of the cradle has near its lowermost end a tubular boss 15 through which the bolt of a lamp can pass before it enters and is secured to the lamp casing.
The major side wall 3 of the cradle carries on its outer surface between the tubular boss 15 and its lowermost edge two strips 17 for identification purposes. Additionally, two countersunk holes 18 are provided in the major side wall 3 for fixing of the nameplate of a user.
Referring to Figure 4, in the preferred battery operated road hazard warning lamp and cradle assembly, the lamp 21 has a casing 22 of rectangular transverse cross-section and has, in each of the major side walls of the casing, a circular lens 23. The lamp 21 is so supported in the cradle 20, which is substantially as described with reference to Figures 1 to 3, that the lamp is pivotable on pivot pins engaging in the tubular bosses 11 and axially aligned holes in the minor side walls of the lamp casing and that the upper arcuate edge 4 of the major side wall 3 of the cradle underlies the lens 23 in the adjacent major side wall of the lamp casing 22 and the lens is exposed.The lamp 21 has a mounting bolt 24 which passes through the tubular boss 15 of the major side wall 3 of the cradle 20, through the lamp casing 22 and screws into an internally screw threaded hole in a pad 25 secured to the outer surface of the casing to retain two electric cells in the lower part of the casing.
The cradle 20 is mounted on an upstanding post P of circular cross-section by means of the downwardly extending tubular boss 5 which effects a snap-fit on the upper end of the post.
When it is required to replace an electric cell or the electric cells of the lamp 21, a knife blade is inserted between the upper surface of the base 1 of the cradle 20 and the undersurface of the lamp casing 22 to depress the leaf spring 12 to enable the lamp to be pivoted out of the open side of the cradle to facilitate replacement of the cell or cells.
Actuation of the slidable operating switch of the lamp is effected by an elongate tool through one or other of the apertures 14 in the minor side walls 2 of the cradle 20.
