No. 820,710 Claims priority, application Germany Apr. 25, 1959 4 Claims. (Cl. 240-71) The present invention relates to a pulling-lamp-fixture with aspring pull operating in one direction, which spring pull is disposed preferably in a ceiling canopy. The lamp cord carries at one end the lamp socket and the fixture,

respectively, while its other end may be wound on a Winding drum rotatably mounted in a frame and adjustably spring biased. The winding drum has furthermore means for transferring current between the network and the lamp cord.

It is one object of the present invention to provide a pulling-lamp fixture including a spring-pull, which will project only a relatively short distance beneath the ceiling upon which it is mounted.

It is another object of the present invention to provide a pulling-lamp-fixture wherein the bushing, which supports the spring-pull frame, projects through the bottom of the ceiling canopy in downward direction and is connected with a covering or centering cap which has an inner threaded collar and covers the bushing together with the entire bottom of the canopy and which has preferably a different color than that of the canopy.

It is yet another object of the present invention to provide a pulling-lamp-tixture wherein the conically formed covering or centering cap is equipped with a threaded collar which projects into the bottom of the ceiling canopy and which receives the bushing over the entire length of the latter and is disposed flush with the inner side of the bottom of the canopy. The outer edge of the cap engages the shoulder of a ring projecting axially in downward direction, which shoulder is formed by the bottom of the canopy.

With the structure designed in accordance with the present invention it is possible that the ceiling canopy which receives the spring-pull appears optically much lower than the known structures, since the construction height of the actual canopy is in this manner reduced for the length of the bushing provided on the frame. The covering cap which receives now the bushing in a covering manner is no more recognized as to the construction height, particularly since advantageously it is in a color different from that of the canopy. This conically shaped covering cap amounts to a reliable solution on the one hand as to the mounting or securing, and on the other hand of an aesthetic and well constructed formation of the bottom of the canopy, and finally makes the total ceiling canopy appear shorter for an appreciable amount, so that this embodiment lives up to all desired requirements of a ceiling spring-pull covered by a ceiling canopy. Threaded nipples or the like do not appear at all in this structure. Furthermore, the axially projecting shoulders of the bottom of the canopy contribute to the safe centering of the cap, while on the other hand the shoulder of the cap which receives the frame bushing secures a safe centering of the spring-pull.

This new embodiment of the present invention brings about also a mounting of the spring-pull frame in an advantageous manner. The mounting of the fixture is achieved in such a manner that by means of the proposed eye or hook, a spring-pull frame needs to be hooked merely to the ceiling hook, whereby the cumbersome mounting by means of a U-shaped, bent securing member, as applied in a known structure, is eliminated.

With these and other objects in view, which will beited States atent "ice come apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:

FIGURE 1 is a pulling-lamp-fixture with a spring pull disposed in the ceiling canopy;

FIG. 2 is a longitudinal section through the ceiling canopy with a spring-pull, partly in section, whereby the bottom of the canopy and the frame bushing are covered by a covering cap; and

FIG. 3 is an elevation of the pulling-lamp-fixture, another embodiment of the covering cap being shown in section.

Referring now'to the drawings, and in particular to FIGS. 1 and 2, a spring-pull 10 is disposed in a ceiling canopy 11, whereby the spring-pull 10 is mounted on a ceiling hook 12. The feeding of electric current from a current source including feeding wires 19 onto the winding cord 22 takes place by means of the axles 15 and 16 which carry ,the respective halves of the winding rollers 13 and 14 and from here over the contact springs 17 and 18, secured to the spring-pull 10 by means of contact screws 22 onto the terminal ends 22' of the winding cord 22, on the end of which the lamp socket 42 together with the lamp shade 43 is mounted. The respective halves of the winding rollers 13 and 14 have substantially halfcircular complementary recesses 13 and 14 through which the winding cord 22 is fed from the interior of the winding rollers 13 and 14 toward their outer faces on which the winding cord 22 is wound.

The spring-pull frame 36, which supports the axles 15 and 16 in an axially aligned position, is held together by means of a frame bushing 40 which, in accordance with the embodiment of the present invention shown in FIG. 3, projects through the bottom 44- of the canopy 11, and is carried by an inner threaded cylindrical member 45 of a covering cap 46. This member 45 projects on the one hand through the bottom 44 of the canopy 11 and terminates at its inner side flush with the latter. Furthermore, the cap 46 has a substantially conical shape and is centrally supported or guided with its edge 47 on an axially projecting shoulder 48 of the bottom =44 of the canopy 11.

In the embodiment shown in FIG. 2 of the drawing, the bottom 44 of the canopy 11 has an axially projecting annular member 49 through which the frame bushing 40 extends, whereby a comparatively short cylindrical member 45 of the covering cap 46 may be screwed on, or merely fit on the free remaining part of the frame bushing 40, and thereby a safe mounting is secured.

The mounting of the spring-pull frame 36 is arranged in such a manner that eyes 30 stamped out from the upper cross member 29 of the frame receives the ends of a fixing stirrup 50 which is interlocked with the eyes 30. This stirrup 50 is in this manner connected with the upper cross-member 29 of the frame and it is not required to mount the stirrup 50 during the mounting of the springpull. The spring-pull is supported from the ceiling hook 12 by means of said stirrup 50.

As already set forth, the shown and described embodiments of the present invention are merely examples for supplying a structure of the present invention and are not limited thereto, rather other embodiments and application are possible within the scope of the present invention. This relates in particular to the constructive formation of the covering or centering cap, as well as its collar, the scope of the present invention being determined by the objects and the claims.

I claim:
