' ANTIVIBRATION DEVICE Filed May '7, 1954 MHW Patented Apr. 16, 1935 UNITED STATES PATENT QFFIQE V AN'rrviBRA'rioN Davies George A; Phinn, Pasadena, Calif. Application May 7, 1934, Serial No. 724,286
5 Claims.
My invention relates to a device for holding curtains against flapping, rattling and vibrations under and in wind pressure and gusts and the objects of the invention are briefly to provide a sim- 5 ple and inexpensive device that will effectively carry out the purposes stated, may be easily applied, will not mar the appearance of the frame or casing and, by maintaining the curtain secure against the curtain frame,
whether of door or window, will preserve the curtain material.
A preferable form of the to windows or screen doors invention applicable is expressed in the accompanying drawing, in which 1 Fig. l is a bottom elevation of a device embodying my invention.
Fig. 2 is a face view of Fig. 1.
Fig. 3 is a plan view.
flexible elements for engagin guiding the curtain slat in it ward movement.
g the extensions and s upward and down Fig. 5 is a fragmentary perspective view of the curtain slat showing one of Fig.6 is a front view of the extensions. a sheave applied in the top of a window or door frame in which a cord is arranged to run to operate the curtain,
' and Fig. '7 is a front view of a Window or door frame, showing a curtain in position and the anti flap devices as applied to the frame.
The invention is applicable particularly to spring roller curtains either f doors and is obviously used in pairs to engage the intermediate edges of the curtain.
Referring to the drawing, plate provided with holes 2 or Windows or screen I designates a base for screws or other devices to fasten same to the side members 3 of a frame or casing 4 for a win dow or door. At one side, the base plate I is provided with a housing 5, in which are journaled two spaced rollers 6 and 6' which project a short distance beyond the housing 5, and, as shown in Fig. 3 are in superposed relation.
At the other side said base plate is provided with upstanding lugs or ears 7 in which is journaled a pivot or hinge pin 8 for one end of an arm 5. which is upwardly disposed The other end of said arm and curves over the surface of the base plate I, thereby providing between it and the rollers 8'5 and H, a space A to accommodate the edge of the curtain, is provided with a shaft l0 upon which is mounted a roller ll of considerably greater diameter than either of said rollers 6 or 6'. the compression of a spring The arm 9 is under I2 which holds the the edges during the operation of the curtain.
The roller 1! i with the arm Q is movable relatively to the rollers 6 and 3' to enable the edges of the curtain E3 to be placed between said rollers and also to permit the roller l I to respond to irregularities in the curtain material and thus prevent injury thereto. This provision of relative movement of the roller H is also made to permit the passage between it and the rollers 6 and 6 of the curtain slat I i when it is pulled upwardly, or when it is lowered during the wind-up of the roller I5, which is a spring roller and whichis held in position at the bottom of the frame t or on a door by the usual curtain fixtures 16. In
order to facilitate the passage of the slat between the rollers, thethickness of same at its respective ends is reduced, this reduction being accomplished by flat bars ll secured to the slat l4. Each flat bar ii is provided with an eyelet l8 which penetrates the curtain l3 and through which is extended a flexible guide member I9 by which the movement of the curtain in either direction is effected always in a straight line. When the devices are applied as shown in Fig. '7, the curtain is securely held by the rollers 6 and 6' and H against vibration and flapping, preserving in this wise the life of the curtain and eliminating the necessity of use for such contrivances as hooks and snaps to hold the curtain against flapping.
By means of a pull cord 26 attached to the slat l4 and running over a sheave 2i in the top of the casing, the curtainmay be raised or lowered.
What I claim, is:
l. A device of the character disclosed comprising a plate arranged to be secured to a window or door frame, a pair of spaced rollers 'ournaled in said plate, a relatively large friction roller contacting said spaced rollers, a journal for said large roller, an arm carrying said journal and pivoted on said base, and means yieldingly engaging said arm to hold said large roller in yielding contact with said pair of rollers,
2. An anti flapping device for curtains comprising a plate arranged to be secured to a winsaid plate, a shaft on said arm carrying said friction roller, a pivotal mount for said arm, and means to hold said roller pressed in yielding contact with said spaced rollers.
3. An anti flapping device for curtains comprising a base arranged to be secured to a window or door frame, a pair of superposed rollers journaled in said base and at one side thereof, an arm hingedly mounted at the otherside of said base, a friction roller journaled on said arm and co-operating with said spaced rollers to grip the edge of a curtain, and means to maintain said friction roller in yielding engagement with said spaced rollers.
4. An anti-flap device for curtains comprising a base, superposed rollers journaled at one side of said base, a compressible roller co-operating with said superposed rollers to grip the edge of a curtain, and a yielding mount for said compressible roller at the other side of said base, said mount curving over the surface of said base.
5. An anti-flap device for curtains comprising a base, superposed rollers journaled in said base and at one side thereof, an arm pivotally mounted upon said base at the other side thereof to have a swinging movement relatively thereto, said arm having a curve free of the surface of said base, a compressible roller journaled in the end of said arm and co-operating with said superposed rollers to grip the edge of a curtain,
and means to maintain said arm under compression to cause said compressible roller to exert a constant yieldable pressure upon said superposed rollers.
