Abstract
An oven has heating units to dry the paint on a freshly painted automotive vehicle. Each heating unit has infra-red tubes mounted on a frame. A reflector plate having a reflecting surface is provided behind the frame. The frame is mounted for swinging movement from an operative position adjacent to the reflecting surface of the reflector plate to an inoperative position allowing access to the reflecting surface to enable the reflecting surface to be cleaned. A quick acting latch is provided to releasably secure the frame in its operative position.
Claims3
Apparatus for drying paint on a vehicle body comprising a drying unit, and means mounting said drying unit adjacent to a painted vehicle body, each drying unit comprising:
- (a) a reflector plate having a reflecting surface,
- (b) a frame comprising elongated spaced apart side frame bars and elongated spaced apart end frame bars connected end-to-end to define an opening,
- (c) heating elements carried by said frame,
- (d) means pivotally attached to one of said end frame bars mounting said frame for swinging movement away from an operative position adjacent to the reflecting surface of said reflector plate to an inoperative position allowing access to said reflecting surface to enable the reflecting surface to be cleaned,
- (e) said heating elements comprising elongated parallel tubes extending across said opening between said side frame bars,
- (f) each of said side frame bars having a channel extending along substantially the full length thereof, said channels projecting laterally outwardly from said side frame bars and in spaced relation to said reflector plate when said frame is in said operative position,
- (g) said channels opening toward one another and receiving the ends of said tubes so that said tube ends are protected and concealed by said channels,
- (h) means individually and releasably securing the ends of the tubes in said channels,
- (i) bus bars attached to said respective channels exteriorly thereof and electrically connected to the ends of the tubes therein, said bus bars, when said frame is in said operative position, occupying the space between said channels and said reflector plate to be protected and concealed thereby,
- (j) and releasable means for securing said frame in its operative position.
Apparatus for drying paint on a vehicle body comprising two drying units, and means mounting said drying units adjacent to a painted vehicle body,
- wherein each drying unit comprises:
- (a) a reflector plate having a reflecting surface,
- (b) a frame comprising elongated spaced apart side frame bars and elongated spaced apart end frame bars connected end-to-end to define an opening,
- (c) heating elements carried by said frame,
- (d) means pivotally attached to one of said end frame bars mounting said frame for swinging movement away from an operative position adjacent to the reflecting surface of said reflector plate to an inoperative position allowing access to said reflecting surface to enable the reflecting surface to be cleaned,
- (e) said heating elements comprising elongated parallel tubes extending across said opening between said side frame bars,
- (f) each of said side frame bars having a channel extending along substantially the full length thereof, said channels projecting laterally outwardly from said side frame bars,
- (g) said channels opening toward one another and receiving the ends of said tubes so that said tube ends are protected and concealed thereby,
- (h) means individually and releasably securing the ends of said tubes in said channels,
- (i) bus bars attached to said respective channels exteriorly thereof and electrically connected to the ends of the tubes therein,
- (j) and releasable means for securing each frame in its operative position,
- and wherein said two heating units are arranged side-by-side such that when the frames of said units are in operative position the adjacent channels thereof cooperate with said reflector plates to define a substantially closed space, said bus bars attached to said respective adjacent channels occupying said closed space to be protected and concealed thereby.
