Description

E. STOCKER DooR CLOSER Filed Sept. 8. 1925 Patented May 24, 1927.
UNITEDv STATES ERNST STOCKER, OF LUZERN. SEVITZERLAND.
DOOR CLOSER.
Application led September 8, 1925, Serial No. 54,972, and in Switzerland September 11, 1924.
The invention relates to a new and improved door-closer adapted to he used for doors` gates and so on.
The main olijeet of the invention is to provide a most simple and etileetive deviee ot this eharaeter which is inexpensive in ronstruetion and whieh ean be readily applied to the eonventional types ot doors.
further ohjeet ot' niy invention consists' in the provision oi' a door-eloser n'hieh does not ofiler any apprcafiahle resifftanee when the door is opened and `which needs no readjustlnent after having been srt onee.
Vi'urther oliieet ot the in\entiou is to provide a door-eloser whieh erm he readily adapted to any size ot' doors to elose the same gently without jamming.
In the drawings aeeon'lpanying and torming part of the present speeifieation`r l have shown in detail tivo ot the several eonvenient `forms ot embodiment ot the invention, which will he set forth fully in the followingl description.
It Will he obvious therefore that I do not restriet myselie thereto; I may depart therefrom in several respects Within the scope ot the invention included in the claim following said description.
Referring to the drawings;
Fig. 1 is a sectional side elevation of the first example ot my door-closer,
Fig. .2 is a top view thereof,
Figs. 3 and 4 show the means to attaeh the door-einser in a top and in a side View,
Fig. 5 shows the seeond form of eonstruetion of the door-closer in a` sectional side elevation` Fig. (i is a top view thereof,
Figs. 7 to 14 show diagrammatieally the manner to attach the door-closer to the door and to the door-easing.
Like ehararters refer to like parts throughout the several figures.
The door-closer shown in Figs. 1 to 4 eomprises an angular support K which is rigidly fixed hy means of screws to the door T. On the horizontal member of the support K a. eireular plate E is tiXed by means of a sei-ew (t engaging a serew-threaded here ot a stud IY) rigidly eonneeted to the plate E. The plate E is provided with a eireular row of'` holes lVt and the support K is provided with a pin N projecting in one of said holes M securing the plate E against rotation. The stud D is provided with a radial slot C and into this slot the inner endpieee of a blade spring F projects. The outer end of the spiral spring F is rigidly eonneeted to a easing H hy means ot' a sel-ew Q and a nut R. To the easing H a guide pin J is rigidly fixed at its centre projecting into the bore of the stud l) and rotatably mounted therein moreover the easing H is fastened to an arm A. The arm is eonneeted to an angle pieee L h v means ot a link Z. The pier-e L is fastened to the door easing by screws and one memhrr L is provided with a numher of holes; L". rlhe link Z engages with one ot its endsy one ot' the holes L and with the other end a hole l in the arm A. By opening or closing the door the easing H with the arm A turns around the stud l) as its pivot.
The parts l( and L ot the door-closer may he. fixed to the doorewinel` and to the dooreasing in the manner shown in Figs. 7 to 14.
ln the arrangement shown in Fig. 7 the support is fixed to the door-Wing T and the angle piet-e L is tiXed to the door-easing; the pieee L is arranged between the support. l( and the hinges of the door it the door is elosed. lt' the distant-e between support l( and hinges O is denoted by r1. and the angle between the parts A and Z is denoted hy B it the door is elosed and B' if the. door is ol'iened, it' l denotes the force of the spring F measured at the point B and Z the foree arting in the direction ot' the link Z then the torque tending to elose the door is If by opening the door its angle with the door easing increases. the value of (siii B) P increases and moreover the foree P increases with the increase of the angle B but in a larger measure while the distance a decreases (see position of the door and the door-closer in broken lines Fig, 1). The foree tending to elose the door ean be kept at least very approximately eonstant hy elosing a spring F of proper strength and the said fol-ee is ehosen to he just a little above that to overeome the friet ion.
vThe relative position of the points ot attachment of the parts K and L on the door and on the door-casing may be as shown in Fig. 8. The support K fixed to the door is
