BY ATTOR‘NEY Patented Nov. 15, 1938 2,136,912 UNITED STATES PATENT OFFICE 2,136,912 HINGE MECHANISM FOR LIGHTING ‘ ‘ FIXTURES ‘ Leroy C‘. DoaneQMeriden, Conn, assignor to The Miller Company, Meriden, Conn.,.a corporation of Connecticut Application May 29, 1937, Serial No. 145,427 '5 Claims. (Cl. 240-735) The present invention relates to lighting ?x tures and is more particularly directedto» hinge mechanism for lighting ?xtures of the ceiling type. The present invention contemplates lighting ?xtures having downwardly depending walls to receive a shade supporting band and recessed to receive a hinge element carried by the band. The band may be a continuous or split band and in 10 cludes means pivotally connecting it to the frame to permit it to be suspended in open position. According to the present invention the band is formed with hinge knuckle such as a channel and the hinge element constitutes a pin or pintle sup 15 ported in the channel and about which the band. may swing, the pin also serving as an alining element when a split band is used. The accompanying drawing shows, for pur poses of illustrating the present invention, an 20 embodiment in which the invention may take form, it being understood that the drawing is illustrative of the invention rather than limiting the same. 25 In this drawing: Fig. 1 is a plan view partially fragmentary to show the assembled ?xture and relative relation of parts for assembly; Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1; 30 Fig. 3 is a fragmentary view of one end of the ?xture showing the hinge support; and Fig. 4 is a section on the line 4—4 of Fig. 1. be split as at 30 to permit it to be sprung open to insert ?ange 24 of shade 22 and when closed to embrace same, and when closed pin l8 serves as an alining and holding member for the split band. 5 When hinge pin I8 is placed in hinge knuckle or channel 28, the band and frame may be hingedly connected by placing one end of pin ill in recess [6 with the other end swung diagonally forward (Fig. 1) until it comes within the pe riphery of face opening [4, whereupon it may be raised and swung rearwardly in groove 28 until it alines with recess I9. Thus positioned the shade will be suspended in open position as shown by dotted outline Fig. 2, whereupon it may be pivoted 15 upwardly, positioning the entire band 20 within the depending walls of frame 2. The band is provided at the end opposite the hinge with a slot 32 into which a latch member 34 may be ro tated by actuating bolt 36 carried in wall [2 to 20 lock the shade in position. There is also provided a supporting plate 38 which could be integral with frame 2 but as shown it constitutes a separate member screw threadedly attached thereto. Depending from the lower face of plate 38 is a clamp 40 prefer ably formed of a strip of resilient metal secured to plate 38 as by rivets 4|. When shade 22 is raised into position, band 28 will tend to raise clamp 40 parallel to the supporting plate 3.8 30 whereby the downward bias of clamp 40 will pre vent chatter of the frame due to vibration such Referring to the drawing, a substantially hori zontal frame is indicated by the reference charac 36 ter 2. The frame is generally rectangular, though other shapes may be used and includes depend ing side walls 4 and 6 and end walls 8 and I ll, the end walls being turned inwardly as at I2 to de?ne a rectangular face opening [4, and also provide second clamp of like nature may be provided to bias the opposite end of the band downwardly 35 on latch member 32. The supporting plate 38 is provided with apertures 42 through which screws 44 may be passed for securing the ?xture to the ceiling, and supports a socket 45 and lamp bulb 40 an external ?nish to the fixture. There is provided in side wall 6 a recess 16 for 46 as indicated. It is obvious that the invention may be em supporting one end of a hinge pin or pintle l8, and wall 4 is provided with longitudinal groove 20 terminating in a recess IQ for supporting the 45 other end of the pin l8. As pin 18 is wider than bodied in other forms and constructions within the scope of the claims and it is to be understood that only the preferred form has been shown and various modi?cations and changes being 45 possible, I do not otherwise limit myself in any way with respect thereto. I claim: 1. A lighting ?xture comprising a substantially horizontal frame having end and side walls, one 50 wall having an interior recess and the opposite the face opening hi, it is positioned by placing one end in recess l8 and moving the other end diag onally in groove 20 to recess l9 (Fig. 4) . The shade '22 may have any desired shape and 50 as shown is provided with a rectangular ?ange 24 adapted to be received in a supporting band 28. The band 26 is formed at one end with a hinge knuckle such as channel 28 for engaging the hinge pin l8, it being understood that other 55 forms of knuckles may be used. The band 28 may as when the device is mounted in a vehicle. A 40 Wall a groove terminating in a recess, a shade, a band for the shade receivable in said frame, and a hinge connection between the band and frame comprising a, pin carried by the band and 55 2 2,136,912 supported in said recesses, said pin being posi tioned by diagonal movement in the groove. 2. A lighting ?xture comprising a. substantially horizontal frame having end and side walls, one wall having an interior recess and the opposite 4. A lighting ?xture comprising a substantially horizontal frame having end and side walls, one wall having an interior recess and the opposite wall an interior groove terminating in a recess, a pin supported in the recess and positioned by diagonal movement in the groove, a shade, a band on the shade receivable in said-frame, and a pin engaging part on the band for hingedly connecting the frame and band. 10 prising a pin carried in said channel and sup- . ., 5. A lighting ?xture comprising a substantially ported in said recesses, said pin being positioned ‘horizontal frame having end and side walls, one wall a groove terminating in a recess, a shade, a band for the shade receivable in ,;the. frame, said band havinga channel therein and. a hinge connection between the band and frame com ' of the side walls having an internal recess and ' 3. A lighting ?xture comprising a substantially ; ‘ theiother a groove terminating in a recess, a shade horizontal frame having end. and side walls, one having a rectangular ?ange, a rectangular band wall having a recess and the opposite wall a for. carrying saidshade receivable into said frame, one end of saidband being split and having a groove terminating in a recess, a shade, a split channel therein, a pin carried in said channel band for the shade adaptable when open to re by diagonal movement in then-groove. ceive the shade and when closed-‘to embrace H and projecting'beyond the ends thereof, said pin the shade, a pin for alining the splitband in, aligning the ends of the bands and being sup closed position, said pin being supportable in said portable in said recesses by diagonal movement 20 recesses and positioned by diagonal movement in-‘said groove to hingedly connect the frame in said, grove to hingedly connect theeframeand and band.
