No. 67,714, entitled Rotating Shade Drop Light Roto Shade, filed Aug. 28, 1970, now abandoned.

BACKGROUND OF THE INVENTION Heretofore, extension lamps of the drop light type which include a suspension hook, lamp bulb guard and handle, together with a reflector, have not satisfactorily provided for light reflection focusing due to their construction. The position of the reflector in such constructions has been affected by torque or pulling on the cord, or the weight of the guard, or position where hung. The cord torque or weight causes the free swiveling hook to turn, for example, or result in a misalignment of the reflector with reference to the work location. In some constructions, adjustment of the reflector could be effected by loosening components of the combination and adjusting the same, with a subsequent fixing by tightening of loosened members. Such constructions preclude, or in any event detract from, facile use of the light for work conditions and positions.

The present invention overcomes these drawbacks and deficiencies in the prior devices.

SUMMARY OF THE INVENTION An extension lamp bulb guard and reflector of the drop light type consisting of a handle, a lamp bulb guard, a suspension hook, and a light reflector wherein the handle, suspension hook, and sometimes the guard, are connected as a unit, and the reflector is mounted for independent rotation. The construction eliminates twisting, misalignment or misdirection of light focusing which might otherwise occur due to weight stress, torque, or tension on the cord in use. In the present construction, since the cord, handle and hook are a fixed or stabilized unit, the reflector can be freely and readily turned to any desired light reflection angle and can be easily varied for different working positions, regardless of placement or suspension of the lamp.

Other and additional objects and advantages of the invention will be more readily apparent from the following detailed descriptions of embodiments thereof when taken together with the accompanying drawings in which:

This application is a continuation-in-part of my copending application Ser. No. 67,714, entitled Rotating Shade Drop Light Roto Shade, filed Aug. 28, 1970, and incorporates the basic principles and structures of this preceding application and further discloses additional specifically different structures for accomplishing the overall end result thereof.

Referring now in more detail to the drawings, the invention is directed to an extension lamp bulb guard and reflector of the type usually associated with and referred to as a drop light or trouble light. Such constructions include a handle 20, fragmentarily shown, a lamp bulb socket 22, and a detachable or removable bulb 24. The electric cord or extension cord, not shown, extends operatively into handle 20 and is electrically connected with the lamp bulb socket 22in a usual manner. Such constructions are usually provided with a suspension hook, generally indicated at 26, adapted for suspending the lamp from any convenient means in proximity to a work location. In heretofore known constructions, these hooks are freely rotatably mounted with respect to the remainder of the unit, with the result that the angular position of a reflector unit associated therewith is affected by torque or pulling of the cord or the weight of the guard or position where hung. Such forces with a free swiveling hook tend to affect the position of the reflector and accordingly focusing of the light on the work area. The present invention, in all embodiments shown and described, eliminates this drawback.

In FIG. 1, a partial bulb cage 28 includes a plurality of shaped wires 30 adapted to partially surround bulb 24, which terminate and are fixed at their upper ends to a spool or thimble 32, with hook 26 being fixed with respect to spool 32 and accordingly wires 30. The lower ends of wires 30 are secured to a cylindrical attachment member 34 which can be in the nature of a split sleeve adapted to pass over the end of socket 22 and can be rigidly secured thereon by means of a conventional split clamp 36 with tightening nutand bolt combination 38. When mounted as shown in FIG. 1, the hook is rigidly fixed with respect to handle 20, or, in other words, is non-rotatable with respect thereto. The partial cage 28 is also non-rotatable with respect to the handle.

In the embodiment of FIG. 1, the lamp bulb guard 40 consists ofa plurality of bent wires 42 attached at their upper ends to a semi-cylindrical collar 44, and at their lower ends to a semi-cylindrical collar 46. The guard 40 is pivotally attached at 48 to a light reflector, generally designated 50, which includes a formed reflector surnector 34. Latch 58 is then operatively engaged with an abutting wire 42 to fasten the combination guard and reflector unit in a freely rotatable manner with respect to a unit formed by the handle, bulb and suspension hook. Due to this freely rotatable mounting, regardless of the position assumed by the handle and hook unit due to forces on the cord or the like, the reflector can be appropriately adjusted to reflect light to the work area.

The embodiment of FIG. 4 functions in the same manner as the preceding embodiment but varies slightly in structure. The hook 26A is again rigidly secured to a connector 34A fixed with respect to handle 20. Reflector 50A is again generally configured for partial surrounding of bulb 24 and has at the upper end thereof an apertured disc 60A which fits over the stem of hook 26A in a freely rotatable manner. A split sleeve 62 engages around connector 34A, and tightener 64 is provided. Guard 40A is hingedly attached at 48 to the reflector and has a bale portion 66 engageable with a friction lock 68 on reflector 58. The association and function is the same as in the previous embodiment, permitting free rotation of the reflector and guard'unit with respect to the handle, hook combination.

In FIG. 6, the modification shown is quite similar to that of FIG. 4, but the reflector 50B is provided with a spring clip 70 at its upper end and a spring clip 72 on collar 74 at its lower end for free rotatable mounting on the hook, handle unit.

In FIG. 7, reflector 50C includes only a lower collar 76 and spring clip 78 for association with. the handle. The hook 26C terminates at its lower end in a split collar 80 for rigid securement on handle 20. Again the reflector, guard is freely rotatable with respect to the fixed handle, hook combination.

In FIG. 8, the reflector 50D has a lower cylindrical collar 82 similar to FIG. 7, with the body of the reflector and hook 26D having a slightly different configuration and ofa generally upper cylindrical configuration. The guard 40D has a lower attachment collar 84 for fixed engagement with respect to handle 20, butwith an open cylindrical upper end 86 formed of wire member 88 on which are pivotally engaged and mounted a plurality of segments 90, which collectively form an end closure, or, when in opened position, permit access to bulb 24. Again, the operation is identicalwith the above embodiments.

In FIG. 9, the hook and

cage

26D and 40D are the same as in FIG. 8. The reflector 50E, however. consists of magnetized material which, through coaction with the wires of guard 40!), permit freely adjusting the relative positions thereof.

In FIG. 10, a still further modification is shown, again including a guard 40F affixed at its lower end 92 with 6 respect to the handle 20. The hook 26F, together with guard 40F, is rigid with respect to the handle. Thereflector 50F, ofa shaped configuration, has a permanent keep it cool.

magnet 94 secured thereon. The operation of this embodiment is similar to that of FIG. 9. Additionally, however, the reflector 50F consists of a double wall construction, including inner wall 96 and spaced outer wall 98, which form an air space 100 therebetween. The air space 100 serves to insulate the outer shade wall to While preferred embodiments have been hereinabove described and shown in the drawings, manifestly minor changes in details of construction can be effected without departing from the spirit and scope of the invention as defined in and limited solely by the appended claims.
