Description
10~776~2 This invention relates to a base for poles, such as lamp poles.
It has been the general practice, up to now, to make the poles and bases in one piece, so that a large inventory of poles of various lengths and sizes mounted on bases of various shapes, were required. This takes up a large storage space. It is also very difficult to satisfy all customers, since it is almost impossible to maintain a complete line having all possible combinations of bases and poles.
It is therfore the object of the present invention to provide a base which is made separate from the pole and can take up a large number of poles of various lengths and sizes.
The base in accordance with the inveotion comprises a first block of concrete of predetermined shape having lateral walls covered with a layer of asbestos cement or plastic, a second smaller block of concrete, of predetermined shape, having lateral walls covered with a layer of asbestos cement or plasti~ and partly submerged into the first block of concrete, and a tubular sleeve embedded vertically into the -first concrete block and extending into a hole of predetermined dia-meter in the first block. The second block and the portion of the tubular sleeve located within the second block serve as a socket for receiving a pole.
A pin, a disc or other structural member, is preferably secured to the sleeve for anchoring the sleeve in the first concrete block and also forms a seat for the second block.
The hole in the second block may be of the same diameter as the outside diameter of a pole which has the same inner diameter as the outer diameter of the tubular sleeve, so as to fit tightly over the tubular sleeve. The hole may also be made of a diameter such as to make the base suitable to receive poles of different sizes. In such an embodiment, a rubber of plastic packing is partly embedded in the .
second concrete block and has an elastic lip contacting the pole, so as to improve appearance of the assembly.
The tubular sleeve preferably extends a short distance above the level of the second concrete block and a setscrew is threaded through the pole for fixing the pole on the tubular sleeve.
When the pole is used tu support an electrical device, an electrical conduit is embedded in the cement between the tubular sleeve and the outside wall of the first concrete block for passing electrical wires.
The invention will now be disclosed, by way of example, with reference to preferred embodiments illustrated in the accompanying drawings and in which:
Figure 1 illustrates a perspective view of a base in accordance with the invention;
Figure 2 illustrates a side view of the base of Figure l;
Figure 3 illustrates a top view of the base of Figure l;
Figure 4 illustrates a section taken along line 4-4 of Figure 3;
Figure 5 illustrates a section view similar to Figure 4 but taken through an alternative embodiment of the invention;
Figure 6 illustrates a section view similar to figure 4 but taken through still another embodiment of the invention;
Figure 7 illustrates a plan section taken along line 7-7 of Figure 6; and Figure 8 is a partial plan section taken along line 8-8 of Figure 6.
Referring to Figures 1-4 of the drawings, there is shown a base made of a first cylindrical block 10, of concrete material, into which is partly submerged a second concrete block 12, of smaller size. Both blocks are covered with a protective layer 14, of asbestos cement or plastic, also used for appear8n~e purpose. The top of the first concrete block is also covered with decorative stones 16. It is to be understood that the base is not necessarily circular in horizontal cross-section, but could be ,, ~
~07767;~
square, rectangular or of other configuration.
A tubular sleeve 18 is embedded vertically in the first concrete block and anchored in the concrete by means of a structural member 20 secured to the sleeve. Such structural member also forms a seat for the second concrete block. The strucutral member 20 may be a pin passing through the tubular sleeve 18 or a circular plate having a hole for receiv- ~
ing the tubular tube and being welded~ or vtherwise secured~ to such tubular ~ -sleeve.
Referring to Figure 4, the second concrete block has a hole therein, which is of the same diameter as the outer diameter of a pole 22 which has the same inner diameter as the tubular sleeve 18 so as to tightly receive the pole 22 between the walls of the hole in the concrete and the tubular sleeve. This may be easily done during casting of the concrete block by inserting a short pipe of the same diameter as the pole over the sleeve 18. The pole 22, after assembly, is secured to the sleeve 18 by a setscrew 24. When the pole is used for mounting an electrical device, such as a lamp, a conduit 26 is embedded in the concrete between the sleeve 18 and the outside wall of the block for passing electrical wires 28.
Referring to Figure 5, there is shown another embodiment for mounting poles of two different diameters~ say 2" and 3ll poles. The base is identical to the one of Figures 1-4, except that the tubular sleeve 18 is of a diameter slightly smaller to receive a 2" pole over it (not shown3, whereas the hole in the second concrete block is of a diameter such as to receive a 3" pole. In order to provide a neat appearance and to prevent water or snow ingress, a rubber, or plastic packing 30, is embedded in the concrete of the second block and such packing has an elastic lip 32 which can fit tightly over either the 2" or the 3" pole~
Referring to Figures 6 to 8 there is sho~n still another embodiment for mount~ng poles of various diameters. Also, the base is ~ o7 ~ ~ ~
arranged so that several bases can be stacked directly on on top of the other in stable condition. Ihe base of Figures 6 to 8 include a first cylindrical block 10', of concrete material, into which is partly sub-merged a second concrete block 12', of smaller si~e. Both blocks are covered by a protective layer 14', 14", of plastic material. The top of the first concrete block is also covered with decorative stones 16'.
A tubular sleeve 18' is embedded vertically in the first concrete block 10' and anchored in the concrete by means of a structural member 20' consisting of an annular part integral with the layer 14" and surround-10 ing the same and extended by vertically positioned triangular webs 20''which abut at their outer ends against the inner surface of the protect-ive layer 14' for the concrete block 10', in order to center layer 14' with respect to layer 14" during pouring of the concrete. An inner plastic layer 14''' lines the inside surface of the hole made in the second concrete block 12'. Said layer 14''' is maintained concentric with sleeve 18' by a washer 20''' surrounding sleeve 18' and fitted within the lower end of layer 14'''. The latter has vertically position-ed triangular webs 14a embedded in block 12' and abutting against layer 14''. The underface of the base is covered by a cap member 34, made of 20 plastic material and having a snap-fit with the protective layer 14'.
The cap 34 has drain holes 36 at its periphery and forms a frusto-coni-cal part 38 extended by an upwardly extending cylindrical part 40, in turn extended by a smaller diameter cylindrical part 42 co-axial with the base. The part 42 has a top 44 provided with two concentric ribs 46 adapted to receive between them the lower end of the tubular sleeve -18'. The cavity 40 is adapted to receive the upwardly protruding portion of the second block 12' of an underlying base when the bases are in stacked position, while the cavity 42 is adapted to receive the ;
free end of the tubular sleeve 18' of the underlying base, all while 30 the edges of the base lie directly on top of the first concrete block of the underlying base. Poles 22', of various diameters, can be inserted within the hole of the second block and rest on the washer 20"'. A pole, - '' , '' '' .
~07'7~ 2 of minimum diameter, would tightly fit around the tubular sleeve 18'.
A pole, of maximum external diameter, will tightly fit against the inner lining 14'''. It is obvious that a shim, not shown, for instance a cylindrical shim of appropriate inner and outer diameterJ can be inserted, also within the hole of the second block, either outside or inside the pole, depending on the diameter of the same, so that both ~.
internal and external faces of the pole will be engaged within the hole.
Also, external shims can be used, having an inner bore of other than circular cross-sections, for instance a rectangular or an hexagonal bore 10 to receive with a tight fit poles having an external cross-section other than circular, for instance rectangular or hexagonal. If the pole is adapted to receive electrical wires for.mounting an electrical device, the base will then have a conduit, such as conduit 26', embedded in the corlcrete of the first block between the sleeve 18' and the outside wall of the block for passing the electrical wires.
Although the invention has beer. disclosed with reference to preferred embodiments, it os to be understood that various modifications could be made to those embodiments within the scope of the claims.
