C1aims (01. 173--328) l The invention relates to holders f r tu ular lampsand refers more particularly to holders for p ev nt ng a id ntal. d sen a ment of fluorese t flames item the r ed sockets of flu escent venu s as :fo o e-of its o t to p ovide a h der of simpl construction which may be readily secured to an-end socket of the lamp fixtu v The invention has forother objects to proide a ol which is s l ent and has a loop which bereadily moved over the'body of an end-socket and clamped in placeby its inherent resiliency; to provide a holder which clea-rs the lamp when in operativ position and engages the lamp when in inoperative: position and in partial engagement with an end socket; and to providea holder which additionally serves to guide the lamp while being installed to align its end contacts with the entrance channel of the adjacent end socket.
With these as well as other objects in view-the invention resides in th novel features of constructien, combination and arrangement of parts, as more fully hereinafter set forth.
In he dr w n s:
Elgar-e 1 is an elevation of a tubular lamp fix: cure and attached holders for the, tubular lamp embodying the invention;
FigureZ is an inside, elevation of one of the sockets of the lamp fixture and an attached lamp holder;
Figure 3 is a bottom plan view thereof;
Figure 4 is a perspective view of a lamp holder prior to attachment.
The invention is designed particularly for use with a standard construction of fluorescent lamp fixture having the end sockets I each of which is provided with the head 2 and depending body 3;- of generally rectangular cross-section having at its lowerend the longitudinally extending open ended entrance channel 4 through which thepair of substantially parallel contacts 5 of the lamp 6 are moved during the installation or removal of the lamp from the sockets. The contacts are in the nature of pins extending longitudinally of and beyond the ends of the lamp.
1 are the lamp holders at the opposite ends of the lamp 6. Each lamp holder comprises a onepiece spring clip preferably formed of resilient wire of circular cross-section and having the loop 8 which during attachment of the clip is movable upwardly and longitudinally over a body 3 to a position adjacent the associated head 2. The loop embraces the body and secures the clip in place by reason of the inherentresiliency of the material forming the loop. The clip alsohas the integral parts 9 which-extend. transversely of the body 3 from the ends of the loop '8 at the inner side of the body and the integral arms ID which extend downward-1y or depend from the ends of the transverse parts. 9 transversely of 'theloqp and the transverse parts, The arms have the curved parts i l which are concave with respect to each other to embrace the lamp s when in operative position in the. sockets, l, the lower ends of these arms formin a gap of appreciably less width than the diameter of the lamp and located at the lower side of the la p QDPO$ 6 e l o 3 and transverse parts 9. The arms also have the terminal parts l2 which diverge downwardly with *espect to each other. The curved parts ll clear the lamp when, the latter is in operative Dosition in the sockets asshown by thedash lines l3 in Figure 2. but the lower end portions of these curved parts engage the lamp when it is in the position shown by the dotted lines 14 in Figure 2 at which time the lowermost contact is below the socket and the uppermost contact is located in the entrance channel of the socket. The vertical median line, between the diverging terminal parts 52 and the lower ends of the curved parts H, is in alignment with the entrance channel 4. As a result, when the lamp is being assembled with its sockets the diverging terminal parts and the lower end portions of the curved parts of the clips serve to guide the lamp. to the sockets by aligning the contacts at the ends of the lamp with the entrance channels of the sockets. Further-more, by reason of the inherent resiliency of the material forming, the clips, these, clips assist in moving the lamp to bringlits' uppermost contacts into the entrance channels after the horizontal center of the lamp has been moved upwardly past th eaps at the lower ends of the curved parts of the clips. I
The loop of each spring clip is of generally rectangular shape corresponding tothe' cross-section of the support body 3 and for the purpose of.
eiiectively frictionally securing each clip to its support body, I preferably curve the bottom It of the loop to form the contacts l6 and I preferably incline the top legs H of the loop to have the contacts l8 adjacent the junctions with the transverse parts 9 substantially opposite the contacts l6 and spaced therefrom a distance less than the transverse distance between the outside and inside ia ces of the support body.
This construction provides for ready assembly or attachment of the spring clips to the supports 3 by spreading and pulling outwardly the transverse parts 9 by gripping the curved parts I l adjacent to these transverse parts. At the same time firm gripping of the clips is assured at both the outside and inside of the support bodies of the sockets.
From the above description, it will be seen that I have provided a simple construction of holder which may be economically manufactured and readily applied to a standard construction of flucrescent lamp fixture. It will also be seen that the holder serves to prevent accidental disen gagement of the lamp. Furthermore, it will be seen that the arrangement of holder is such that it serves to guide the lamp to place while the lamp is being installed and it permits the lamp to be installed or removed by a lamp changing device operated by a person remote from or out of reach of the lamp sockets.
What I claim as my invention is:
