Abstract
Abstract An electrical hazard lamp is provided which includes a body member serving as a head member for a multilegged stand and also as a protective cover above a battery. The head member includes an upper wall and a peripheral downwardly extending flange which collectively define a shallow chamber having an open mouth presented downwardly to receive the upper end of a battery supported from the head member. Leg-receiving sockets are formed in the peripheral flange and legs are releasably secured in these sockets by screws. Alternatively, the legs are irremovably secured in their sockets by rivets arranged to permit the legs to pivot between splayed and compact positions. In the latter arrangement a battery case is releasably attached beneath the head member, the battery case having an outwardly projecting flange which is arranged to constrain the legs releasably in their splayed positions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
290 words
In a hazard lamp comprising a body, a lamp housing formed at least partially of light transparent material and mounted on the body, and electrically energized light source disposed within the housing, means for supporting a battery of electrical cells at a battery station, circuit means for establishing electrical connection between the battery and the light source, and means for supporting the lamp above the ground, the improvement wherein: a. said means for supporting the lamp above the ground comprises legs; b. said body comprises a head member in the form of a cover extending over said battery station; c. fastening means connected to the cover and spaced apart from each other peripherally of said head member around said battery station for fastening said legs to the cover whereby said head member serves both effectively to fasten said legs in supporting relation thereto and to provide weather protection above said battery station; d. the head member includes a top wall and an integral downwardly extending peripheral flange defining a chamber having a downwardly presented opening; e. means are provided for supporting the battery with its upper end portion in said chamber for cooperation between a part of said circuit means within said chamber and terminals of said battery; f. a plate member for supporting at least part of said circuit means is provided; g. said plate member being mounted in downwardly spaced parallel relation to said top wall and upwardly of the lower edge of said downwardly extending peripheral flange to define upper and lower portions of said chamber; h. said upper end portion of said battery being received in said lower portion of said chamber; i. and said upper portion of said chamber containing elements of said circuit means.
Claim 2
Dependent Claim
290 words
In a hazard lamp comprising a body, a lamp housing formed at least partially of light transparent material and mounted on the body, and electrically energized light source disposed within the housing, means for supporting a battery of electrical cells at a battery station, circuit means for establishing electrical connection between the battery and the light source, and means for supporting the lamp above the ground, the improvement wherein: a. said means for supporting the lamp above the ground comprises legs; b. said body comprises a head member in the form of a cover extending over said battery station; c. fastening means connected to the cover and spaced apart from each other peripherally of said head member around said battery station for fastening said legs to the cover whereby said head member serves both effectively to fasten said legs in supporting relation thereto and to provide weather protection above said battery station; d. the head member includes a top wall and an integral downwardly extending peripheral flange defining a chamber having a downwardly presented opening; e. means are provided for supporting the battery with its upper end portion in said chamber for cooperation between a part of said circuit means within said chamber and terminals of said battery; f. a plate member for supporting at least part of said circuit means is provided; g. said plate member being mounted in downwardly spaced parallel relation to said top wall and upwardly of the lower edge of said downwardly extending peripheral flange to define upper and lower portions of said chamber; h. said upper end portion of said battery being received in said lower portion of said chamber; i. and said upper portion of said chamber containing elements of said circuit means.
Claim 3
Dependent Claim
132 words
The structure claimed in claim 1 wherein: a. said legs are structurally separate from each other; b. said fastening means provide for movement of said legs between splayed positions and compact positions; c. the body includes a leg control element; d. means are provided for securing the leg control element to the head member selectively in either of a first and a second position; e. said leg control element is provided with means which, when it is secured to the head member in the first position, cooperate with said fastening means for rigidly restraining the legs in their splayed position; f. said leg control element is formed for cooperation with said fastening means for permitting said legs to assume their compact positions when the leg control element is in its second position.
Claim 4
Dependent Claim
73 words
Structure claimed in claim 1 wherein: a. said fastening means comprise sockets formed integrally with said peripheral flange and b. the means for supporting the battery comprise a battery case having an upwardly presented opening and being releasably secured beneath the top wall of the head member by securing means arranged for detachment of the case from the head member while the head member and the lamp housing remain supported by the legs.
Claim 5
Dependent Claim
38 words
The structure as claimed in claim 3 wherein: the fastening means detachably connect the legs to the cover and a bracket is provided on said peripheral flange for enabling the lamp to be mounted on a separate support.
Claim 6
Dependent Claim
48 words
The structure claimed in claim 4 wherein: a. said head member is a one-piece member, and b. the bracket and the body are releasably attached to each other by interfitting male and female parts, one on the bracket and the other being an integral part of the body.
Claim 7
Dependent Claim
38 words
The structure claimed in claim 1 wherein: a. the plate member has apertures therein, b. the battery has terminals projecting through said apertures and provided with means for holding the battery in assembled relation with said plate member.
Claim 8
Dependent Claim
53 words
The structure claimed in claim 1 wherein: a. the downwardly extending peripheral flange includes a generally horizontal step portion extending outwardly from the lower end of an upper wall portion to the upper end of a lower wall portion of said flange, b. said plate member is secured releasably to said step portion.
Claim 9
Dependent Claim
54 words
The structure claimed in claim 1 wherein: a. said top wall of said head member has an aperture, b. said housing has a spigot means open at its lower end releasably secured in said aperture, c. said circuit means extends from said upper portion of said chamber through said spigot means into said housing.
Claim 10
Dependent Claim
64 words
The structure claimed in claim 2 wherein: a. the means for supporting the battery comprises a battery case having an upwardly presented opening, b. the battery case is releasably secured to the underside of the head member and projects below the head member, c. the battery case is formed at its upper end with an outwardly extending flange which constitutes the leg control element.
