Description
y 8, 1965 H. WIEGELMANN ETAL 3,184,593
POLE-MOUNTED LAMP Filed Nov. 8, 1962 1-7 F/GI/ IN VE/VTORS:
Hubert Wz'egelmanrz Jars/ 6 Hillier United States Patent Claims. 61. 240-52 This invention relates to lamps on poles, and more specifically to an oblong lamp for bracket poles.
In the known constructions the offset socket of the pole is inserted into the lamp housing through a ring and fastened by two bolts passing through this ring and provided with lock nuts. It is also known to fasten the offset socket in the lamp housing by a clamp tightened by two screws, or by other solid components.
While such lamps serve their intended purposes within certain inherent limitations, they have several disadvantages.
To avoid these disadvantages the invention provides a pole-mounted lamp which comprises at least one concentrically flexible clamping bushing for mounting the lamp housing on a pole, and a clamping means surrounding said clamping bushing and establishing a rigid connection between said lamp housing and said pole.
It is an essential feature of this invention that there is provided not a rigid but a concentrically flexible clamping bushing which ensures an all-round and uniform close fit of the lamp around the circumference of the pole. The clamping means are preferably designed as a clamping strap and placed around the clamping bushing and can be tightened by means of a single bolt so that the lamp mounting as proposed by the invention excels through greater simplicity and functional eificiency of at least the same reliability when compared with the hitherto known clamping means.
It is a further feature of this invention to provide the clamping bushingor clamping bushings when several are being used-with a cylindrical part closed round about and with projecting lugs. The clamping strap encircling the clamping bushing presses the cylindrical part as well as the lugs tightly against the circumference of the pole. The strength of the wall of the clamping bushing has to be selected in accordance with the deformation of the material taking place. As suitable material a light metal such as aluminum is recommended. Instead of dividing the clamping bushing into a cylindrical part and into projecting lugs the entire clamping bushing may be designed cylindrically, an all-round flexibility being attained by appropriate slots.
Particularly with respect to longitudinal lamp housings for fluorescent lamps to be mounted on bracket poles the invention proposes inserting the pole end into the lamp housing and to construct the well-known lead-in socket as a clamping bushing. It might be expedient to have the inserted pole end fastened by a second clamping bushing within the lamp housing. Regarding the alignment of the longitudinal lamp housing to the bracket pole it is advisable to design at least one of the two clamping bushings laterally adjustable.
The suggestion according to this invention to use a clamping bushing as a clamping element is particularly furth red by the suggestion of forming the clamping biishing", used as the lead-in socket of the lamp housing,
directly from the material of the lamp housing. In this connection use is made of the fact that the strength of the material suitable for the clamping bushing is substantially the same as that of the sheet metal of the lamp housing and the material of the housing, e.g. aluminum, is highly 3,184,593 Patented May 18, 1965 suitable as material for the clamping bushing. Such a design of the lamp is. of particular advantage in that special clamping elements can be dispensed with.
A preferred embodiment of the invention will now be described by way of example and with reference to the accompanying drawing, in which:
FIG. 1 is a longitudinal section through a lamp mounted on the upper end of a bracket pole;
FIG. 2 is a cross section, on a larger scale, taken on the line IIII of FIGURE 1, and
FIGS. 3 and 4 are side elevational views, partly in longitudinal section of the lamp and particularly the lead-in socket.
FIG. 1 shows a bracket pole 1 having an oifset socket 3 inserted into the interior of a lamp housing 2. The lamp housing 2 and the bracket pole 1 are connected at the rearward end 4 and the forward end 5 of the socket 3. The construction of these connections, especially of the one at the rearward end 4, is shown in FIGS. 3 and 4 in detail. As shown in FIG. 3 the lamp housing 2 is flanged and forms a short cylindrical part 6 ending in lugs 7. This part 6 and the lugs 7 constitute a concentrically flexible clamping bushing which engages over the total or at least an essential part of the circumference of the inserted socket 3 of the bracket pole 1.
FIGS. 2 and 4 show a clamping strap 9 which surrounds the clamping bushing and is tightened at laterally projecting ends 19 by a bolt 12, so that the clamping bushing has a tight seat on the socket 3. Between the two laterally projecting ends 10 of the clamping strap 9 there is fastened one side of an angle 11 the other side of which is fixed to the lamp housing 2. The clamping strap 9 can, already prior to assembly, be undetachably fastened to this angle 11.
As illustrated in FIGS. 3 and 4 the exterior part of the bracket pole 1 has a larger diameter than its inserted socket 3. A packing 8 may be inserted between the shoulder on the bracket pole 1 and the face of the lamp housing 2.
The invention provides an easy and positive mounting of the lamp on the end of the bracket pole. Assembly from a ladder is a simple matter. The tightening of a single bolt nut of the clamping strap 9 will sufiice to secure the lamp housing 2 to the socket 3 undetachably and lastingly. This results in savings of material, especially when the clamping bushing is directly shaped from the sheet metal of the lamp housing 2 by stamping or cutting out that portion of the end face of the housing 2 which lies within the dot and dash lines 13 in FIG. 2. In addition, less space will be required than is necessary for the known clamping means such as set screws or pipe straps.
We claim:
1. A pole-mounted lamp comprising a lamp housing, said lamp housing including an integral wall portion, said wall portion defining a bushing, said bushing including a base portion adjacent said wall portion and an end portion terminating in the interior of said housing, said bushing being generally tubular, the end portion of said tubular bushing being formed with a plurality of spaced lugs,
and means surrounding said bushings for clamping said bushing and the lugs thereof against an end portion of a pole lamp adapted for insertion through said opening and bushing.
2. The pole-mounted lamp as defined in claim 1 wherein said clamping means is a clamping strip having ends, and means at said ends for contracting said strap.
