6 Claims.

This invention relates to lamp guards of the type which is detachably connected to a handle guard which is preferably made of soft flexible rubber.

An important object of the invention is to pro vide a new and improved locking or clamping element whereby the guard may be locked quickly and readily in position and immediately released upon the pressing of two compression fingers.

Another object of the invention is the provision of a lamp guard having a two-part collar -'assembly with a compression ring engaging the guard at or adjacent the collar to lock the twopart guard frame together, to permit quick and easy operation of the device so that the frame may be spread apart for the insertion or removal of an electric lamp.

A further object of the invention is the provision of a new and improved locking arrangement which may be applied either at the upper end or at the lower end of a two-part lamp guard so that the lamp guard will be operatively locked in position on the handle and permit quick and easy release so that the guard may be opened for insertion or removal of the electric lamp.

A still further object of the invention is the provision of a lamp guard which is made in two "parts, the two parts having relative movement to permit the insertion and removal of a lamp globe, there being a clamping element consisting of a compression ring with compression fingers to lock the two parts of the guard together and to cause that part of the guard which surrounds the handle to clamplngly squeeze the handle so as to lock the two parts of the guard to gether and to secure an electrical socket in position in the rubber handle guard.

Numerous other objects and advantages will be apparent throughout the progress of the following specification.

The accompanying drawing illustrates a selected embodiment of the invention and the views therein are as follows:

Fig. .6 is a top plan view of a modified form of guard shown in Fig. 7;

Fig. 7 is a detail elevational view of the modifled form of lamp guard.

The particular lamp guard herein shown for the purpose of illustrating the invention comprises a plurality of vertical supports or wires 6 to which one or more transverse horizontal wires 1 are rigidly fastened, such as by welding, soldering, or otherwise. These horizontal supports or wires I are splitat opposite sides, as indicated at 8, so that the guard may be spread apart for the insertion or removal of a lamp globe. A lower collar 9 is made u of two parts In and II, each part having a circular portion I 2 which is rigidly connected to the opposing parts Hi and H of the guard. The vertical wires 6 have their bottom ends rigidly secured by welding or otherwise to the respective parts of the collar 9. The upper ends of these wires are secured to an upper supporting member I 3 which may be a disc to which the vertical wires are connected by passing through openings at the periphery of the disc. or the member l3 may. comprise a two-part collar construction, indicated generally by the numeral a certain amount of flexibility or is pivoted to permit the guard tobe spread apart. In these figures, the guard is spread apart at its lower end to permit the removal of the guard from the rubber handle member Hi to permit ready and instant removal or insertion of a lamp globe. Instead of having the vertical wires 6 pivotally connected at the top as indicated in Figs 1 to 5 inclusive, the guard may be operatively connected at its lower end as shown in Figs. 6 and '1 with the upper part adapted to be spread apart. In Figs. 6 and 7, the collar 9 is operatively hinged together, there being converging legs It at each end of the part collar I0 and H. These legs are ivotally connected together as indicated at H, Fig. 7, in any convenient manner, such as by passing a rivet through the extremity of the legs. In Fig. 7, the collar 9, therefore, includes extensions on parts I Ii and H which are pivotally connected at H. In the device shown in Figs. 6 and 7 vertical wires 6 have their bottom ends secured to the respective parts of the collar 9 and their upper parts secured to the respective parts of or the two-part collar H. The two-part collar ll comprises the parts I. and II which are split along the line I.

Regardless of whether the lamp guard is constructed with a pivoted bottom collar, as shown in Figs. 6 and .7, and adapted to be spread apart at the top, or whether the guard comprises the lower split collar pivotallyconnected at the top to the washer is, it is free to be spread apart along the line 4. Where the legs I are used, the collar 9 is adapted to be spread apart by moving the upper sides outwardly. This arrangement provides an elongated receiving opening when the two parts of the guard are spread apart on their pivots II. The legs I, therefore, provide means for forming an elongated opening to permit the handle guard I! to be inserted readily and quickl within the collar 0. If desirable, a supporting hook 24 may be operatively connected to the top member it whether it comprises the disc shown in Figs. 1, 2, 3, or whether it comprises the split collar l4 shown in Figs. 6 and 7.

,The lamp guard in either of its forms is adapted to be locked to the rubber handle guard ing the two parts of the lamp guard together.

This clamping member may fit around the bottom of the lamp guard, as shown in Figs. 1

I and 4, or it may fit around the upper two-part collar portion I4, as shown in Figs. 6 and 7. Regardless of whether the clamping member 22 is positioned at the top or at the bottom of the guard, the clamping member will have operative engagement with the two parts of the guard. The clamping member 22 comprises a single strand or length of resilient wire coiled so that its free ends overlap a predetermined distance, thereby providing a one-piece compression ring which is adapted to fit around either collar 4 or II so as to lock the two parts of the guard together. Free ends 23 of the compression ring 22 are provided with turned ends 24 and 25, forming compression fingers whereby the compression ring may be expanded to permit it to fit over its cooperating collar. When the ends 24 and 25 are pressed inwardly, the size of the compression ring 22 is increased sufficiently to ment 3, l4. These ends 24 and 25 also protrude 'outwardly a predetermined distance from the ring, as clearly shown in Figs. 3 and 4, and therefore provide rests or legs 26, Fig. 4, so that the guard and its cooperating handle will be provided with supports preventing the member from rolling when it is laiddown. This clamping member 22 is so constructed that it will cause locking engagement of the two parts of the guard and allows the same to be quickly and readily unlocked to permit the guard to be spread apart, no tools being needed to cause such attachment or detachment.

In Figs. 1 to 5 inclusive, the compression ring 22 is shown arranged at the bottom of the guard and tends to squeeze the guard against the soft rubber of the handle member It. This squeezing or compression action of the member 22 also is. In Figs. 6 and 'i the lower ends of the guard are pivotally connected together at II, while the upper end of the guard has a two-part collar around which the compression ring 22 engages to squeeze the parts together. In these latterfigures, the bringing together of the upper parts of the guard causes the same squeezing action to occur about the enlarged portion of the rubber. handle guard II. The compression ring, regardless of where it is positioned, will draw the two parts of the guard together and hold the same in locked position with respect to the handle guard.

The invention provides a lamp guard which is provided with a compression ring and compression operating fingers for permitting the guard to be clamped to its supporting handle or to be operated so that the two parts of the guard may be spread apart instantly to permit quick and easy insection or removal of a lamp globe. Moreover, the clamping action caused by the compression ring permits the guard to be clamped in locked postion by a mere release of the compression fingers 24 and 25. The clamping or compression ring 22 is preferably made as one piece and having its ends overlapping in spiral form, as clearly shown in Figs. land 3. In order to permit easier operation of the fingers 24 and 25 to permit expansion of the member 22, the free end of the upper wire 21, Fig. 2, may be bent downwardly, as indicated at 24, Fig. 3, while the lower member 20 may be bent upwardly, as indicated at 24, Fig. 3.

The guardis relatively'inexpensive. to manufacture and: it may be readily and quickly assembled. Moreover, the particular construction of the upper and lower collars permits the guard to be spread apart a considerable distance, thereby afiording plenty of room forchanging a lamp globe. Moreover, the particular shape and construction of the compression member 22, including its compression fingers 24, 25, which act as supporting legs 2, permits the guard to be quickly and readily applied to the handle guard is. Also, this member allows the handle guard it to be quickly and instantly removed from the lamp guard.
