HINGE FOR DA VENPOBTS 0B SOFA-FEDS.
Specification of Letters Patent.
' Applicationfiled February 5, 1912. Serial No. 675,449.
To all whom it may concern.
Be it known that I, JOHN SONTHEIMER, a citizen of the United States, and a resident of Lincoln, in the county of Lancaster and State of Nebraska, have inventednew and Improved Hinges for Davenports or Sofa-Beds, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved hinge structure for use with sofa beds adapted to properly con-- nect the seat and back frames and the base, and at-the same time admit of easy manipulation of the front and back in moving the same from one. position to another.
A further object of the invention is the arrangement of an improved hinge structure including a pawl designed to be moved pivotally and longitudinally, and engage a plurality of stops or pins, whereby the seat and back associated with the pawl may be adjusted to any angle in respect to each In carrying out'these objects, a base of any desired construction is provided which has associated therewith aback and seat frame. The back and seat frames are pivot-- the seat is moved to a predetermined position the pawl is disengaged for permitting the two frames to act independently in' order that they may be moved so as to occupy the same horizonal plane.
A practical embodiment of the invention is represented. in theaccompanying drawings forming a .part of this specification, in which similar characters of reference indicate corresponding parts in all the views. I
Figure 1 is a side view of a daven ort or sofa bed embodying the invention; ig. 2 is a longitudinal central vertical section through Fig. 1; Fig. 3 is a fragmentary side view of one of the hin es and surrounding parts of the frame s owing the pawl in its disengaged position Fig. 4 is an edge view of the structure shown in Fig. 3; Fig. 5 is a view similar to Fig. 3, but showing the pawl in its position just prexY-ous to that JOHN SOmEIIER, Q1 LINCOLN, NEBRASKA Patented Nov. 12, 1912.
shown in Fig.3; Fig. 6 is a view similar to Y Flg. 3 except that the seat is shown as partiallv lowered and the pawl in an inoperative pos tion; and Fig.7 is a fragmentary longitudinal vertical section through the structure shown in Fig. 1 after the same has been moved to a complete open position for use as a bed. Y
Referring to the accompanying drawings by numerals, 1 indicates a base of any usual or preferred form, 2 a seat frame, and 3 a back frame. These frames of course may be made of any shape and size properly acting together and for acting as seat frames and back frames, and also as means for defining a bed when moved to the position shown in Fig. 7.
A hinge for each side of the frames2 and .iis provided, but as the same are of identical construction a description of one will suflice for both. As clearl drawings, the hinge 4. is ormed/ of three members,-namely a leaf or plate 5, a leaf 6,and a pintle 7. By means of these hinges the frames 2 and 3 are mounted so as to pivot freely in respect to each other, but are guided and controlled by a I and by linke 9 and 10. The link 9 is pivotally connected at 11 to the back 3 and at 12' to the rear part of the base 1. The link 10 is j ournaled on the pintle 7 and is pivoted it is desired to turn the frames from the position shown in Figs. 1 and 2', to the position shown in Fig. 7.
The pawl 8 is pivoted at 14 tothe leaf 5 on the seat 2 and extends substantially in a horizontal line toward the rear until the same engages a stop 15. The stop 15 is connected with an extension of the leaf 6 so that the pawl may hold the back at any desired angle. At the rear end the pawl 8 is formed at a slight angle to its general direction and the angle ortion is rovided with a plurality of note cs 16 whic are designed to accommodate the stops. It will shown in thepawl 8 be evident that any number of notcheslfi may be provided for giving any desired adand forth movement is necessary in order to permit the pawl to move longitudinally when the cam surface 18 engages the stop 15, and when the cam surface 19 engages: the stop 20. These camsurfaces engage the respective stops at the same time and by a continued pivotal movement of the ,seat the pawl will move longitudinally and finally permit a notch 21 to drop over the stop 20. This will lock the pawl 8 in an inoperative position, as clearly shown in Fig. 6. This locking of the pawl 8 is necessary when it is desired to move the back frame 3 and the seat frame 2, tothe position shown in Fig. 7. As soon as the frames have reached approximately the osition shown 'in Fig. 6, the upper edge 0 the awl 8 engages a stop 22 projecting froinlt e leaf 6. This will cause a disenga' ement of the stop 20 from the notch 21.- en this has occurred the pawl drops downand rests on the smooth surface 23 against the stop 15. It remains in this position as long as the seat and back are left in the osition shown in Fig. 7, but upon a pivot upward movement of the seat 2, the same will slide over the stop 15 until the stop 15 has en aged in some of the notches 16. After this as'occurred the seat 2 may then be forced downward against the base 1 which will cause the back 3 to oveupward to the position shown in Figs. land 2.
Iiioperation, when the device is in the posishown in Figs. 1 and 2, and it is desired toraise the back to a more vertical position, the same may be done merely by pushing against the back until the same has reached the desired perpendicular. If it should be desired to transform the device into a bed,
"as shown in Fig. 7, the seat at any desired point, is grasped and raised pivotally to the .i i t position shown in 3, and then lowered tothe position shown in Figs. 6 and 7, Fig. 6 showinlgan intermediate position. In ade' device from the position shown in Fig. 7, to that shown in Fig. 1, it is only necessary to raise the back to the desired an- ,gle and the seat will automatically slide to the rear according to the degree of angle of the back. By the construction and arrangement of the pawl 8 and the associated de-.
vices, the frames 2 and 3 may be adjusted to any desired position by merely shifting pivotally either the position of the seat or' the back, as occasion may require, the pawl 8 acting automatically. Also by the arrangement of the links 9 and 10 the seat and back frames 2 and 3 are substantially evenly balanced so that it will require but little a bed to a device which will act as a chair or daven ort. It wil be noted that by the use of the links 9 and 10, and'pivot pin, the working of the bin e is substantially noiseless. The awl 8 is oosely mounted so that no bind- 'mg will take placeas the same moves from one position to another.
'Having thus described my invention, I claim as new and desire to secure by Letters Patent:
