1 Claim, 3 Drawing Figures PATENTE'BFEB S1914 RICHARD SAPPER INVENTOR AGENT BACKGROUND OF THE INVENTION DESCRIPTION OF THE PREFERRED EMBODIMENTS.
With reference to FIG. 1, the lamp according to the The present invention relates to a lamp with an artic- 5 invention in a first embodiment comprises a base 11 supulated support for use as a table, floor or hanging lamp.
Conventional lamps with articulated supports, such as those for drawing boards, have the disadvantage of requiring the use of springs each time it is desired to lessen the force required for making the various possible movements, resulting in constructional complications and the development of slackness and faults in the mechanical parts after a certain period of operation.
A further disadvantage of conventional lamps with articulated supports is that they need to be solidly clamped, for example to the drawing board or a normal table, so that they do not overturn.
SUMMARY OF THE INVENTION An object of the present invention is to largely elminate the aforementioned disadvantages relative to conventional lamps by providing a lamp with an articulated support which is extremely manageable, of simple construction, long lasting and which does not require clamping when used as a table lamp.
Another important object of the invention is to provide a lamp in which the necessary electrical connections are very easily arrangd.
According to the invention there is provided a lamp with an artictulated support which comprises a plurality of arms disposed in cascade, i.e. one successively connected to another and connected in an articulated manner to each other at intermediate points, the tenninal arm supporting at one end the lamp holder and its relative accessories and at the other end a counterweight arranged in such a manner that the center of gravity of said terminal arm and the components supported by it coincides substantially with the axis of the articulated joint of said arm, each other arm having one end connected in an articulated manner to the successive arm in the direction of the terminal arm, and its other end supporting a counterweight arranged in such a manner that the center of gravity of said other arm with all the components supported by it coincides substantially with the axis of the articulated joint of this latter arm. In other words, the counter-weight of the lamp-carrying arm balances the latter around its fulcrum at the intermediate point while each arm more distal from the lamp-carrying arm has a counterweight positioned to balance it and thus compensate the weight of all following arms and the lampholder.
BRIEF DESCRIPTION OF THE DRAWINGS.
The invention will be more evident from the following detailed description of some preferred but not exclusive embodiments of a lamp with an articulated support according to the invention, illustrated by way of example in the accompanying drawing in which:
FIG. 1 is a diagrammatical view of a first embodiment of a lamp with an articulated support according to the invention;
FIG. 2 is a perspective view of a second embodiment of a lamp with an articulated support according to the invention; and
FIG. 3 shows a detail relative to the articulated joints of the lamp according to the invention.
porting a vertical stem 2 to the end 3 of which is connected in an articulated manner an arm 4 of which one end carries a counterweight 5, and the other end is connected in an articulated manner at 6 to the terminal arm 7.
This latter arm is provided at one end with a counterweight 8, and at its other end an assembly 9 comprising the lamp holder and its relative accessories. More precisely the assembly 9 comprises an internal reflector l0 and an external shield 11 containing a plurality of upper perforations 11a and spaced from said reflector l0, and having a conformation such as to permit a flow of air between the components 10 and 11 for cooling purposes, so as to allow the use also of halogen lamps which are known to produce a large amount of heat.
the counterweight 8 is arranged in such a manner that the center of gravity of the complex comprising the counterweight, the arm 7 and the assembly 9 coincides with the axis of the articulated joint 6. In this manner a universal equilibrium condition is attained by which the assembly 9 may be positioned at any point on the dotted circumference 12, with the position attained being in each case maintained.
In a like manner the counterweight 5 is arranged in such a manner that the complex comprising said counter weight, the arm 4, the counterweight 8, the arm 7 and the assembly 9 has its center of gravity on the axis of the articulated joint 3. In this case a universal equilibrium condition is also attained, by which the articulated joint 6 may be brought into any position on the dotted circumference 13, with the position attained being in each case maintained for any position of the terminal arm 7.
From the aforementioned, the operation of the lamp according to the invention is evident.
As the masses of the various parts of the lamp are in constant equilibrium, the base 1 does not require clamping and may be simply rested on a table.
The assembly 9 may be comfortably positioned at any point compatible with the length of the arms 4 and 7, using minimum force and without requiring the use of auxiliary means such as springs or the like.
The double shield conformation of the assembly 9 means that the external shield 11 may be gripped with the hands without risk of burning, even if halogen lamps are used.
In addition to the table arrangement, a hanging arrangement may be provided in which the stem 2 is fixed by conventional means to the ceiling or a wall.
Advantageously the stem 2 and the arms 4 and 7 each comprise to parallel rods, as shown in the embodiment of FIG. 2, forming an articulated pair of supporting components with this arrangement, a single suitably insulated electric wire may be passed internally through each component of the pair of supporting components 2, 4 and 7. With the modification shown in FIG. 2, it is possible to fix a transformer 14 to the base I so that the lamp may be supplied at low voltage. In this case instead of including insulated wires, the current may be made to pass through the pair of supporting components 2, 4 and 7 constructed of metal and suitably insulated one from the other.
In the design shown in FIG. 2, cross pins are provided at the articulated joints 3 and 6, with the joints at the pin ends.
In order to compensate manufacturing tolerances and other slight disturbances in the aforementioned equilibrium system, friction means are provided which automatically take up the play.
For example, as shown in FIG. 3, each joint at the ends of pins 15 comprises a mushroom shaped member 16 with a cavity housing a spring 17 adapted to thrust a friction ring 18 against the corresponding component of the arm 4 or arm 7. Said component is thrust in its turn against the surface of a substantially U-shaped body which is fixed, for example by welding, to the corresponding component of the stem 2 or arm 4, according to whether the articulated joint 3 or the articulated joint 6 is considered. The stem of the mushroom shaped member 16, into which one end of the cross pin 15 is inserted, is also fixed to the body 19. In this manner the component 4 or 7 may be moved on overcoming a certain friction force determined by the action of the spring 17.
Said spring further ensures the automatic take up of play.
In one modification the articulated joints 3 and 6 may be made using one or more magnets as the friction force.
In another modification, the acticulated joints may be constructed with friction surfaces which also serve simultaneously for transmission of the electric current.
As may be seen, the lamp according to the invention is of rational and at the same time simple construction, so ensuring very easy operation and long life.
The invention so conceived is susceptible to numerous modifications all of which fall within the scope of the inventive idea. Thus for example the number of arms may be increased at will following a succession arrangement according to the aforementioned criterion, i.e., arranging counter-weights in such a manner as to make the centers of gravity of the various parts coincide with the axes of the articulated joints.
