Claims.
Another object of thel invention is the provision of a device or opener of this character, wherein the mechanism for controlling the opening of the door or closure is of novel form, as the door will be controlled to avoid the slamming of the same Aor striking a person entering a doorway by quick and sudden closing movement of such door or closure.
A further object of the invention is the projfision of a device or opener of this character, wherein the same is of great convenience in warehouses'and restaurants, and in fact in any place where owners orV employees habitually have their arms and hands full or shoulders loaded with .",foods and wares making kit practically impossible to manually handle the door or closure sojthat by actuating a foot pedal or stirrup the full opening of the door or'closure can be effected automatically. I y
A still further object of the invention is the 'provision of a device or opener of this character,
which is comparatively simpleY in construction,` thoroughly reliable and emvcient` in operation, strong, durable, automatic of operation, and in-l expensive to manufacture and install.
With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention, and pointed out in the claims hereunto appended.
In the accompanying drawings:
Figure 1 is a horizontal sectional view taken transversely through a door frame and door with the invention applied in accordance therewith.
Figure 2 is a sectional view on the line 2-2 of Figure 1 looking in the direction of the arrow.
Figure 3 is a sectional view on the line 3--3 of Figure 2.
(Cl. 26S- 36) Figure 4 is a fragmentary sectional view on the line 4-4`of Figure 1. Y
Figure 5 is a sectional view similar to Figure 4 but showing operating means holding door in open position.
Figure 6 is a sectional view on the line 6--6 of Figure 5.A
Figurer! is a sectional view on the line 7-'7 of Figure 6.
Figure 8 is a sectional view on the line 8--8 of Figure 2. f l
Figure 9 is a fragmentary vertical sectional View of door support or pivot bracket.
Similar reference characters indicate corresponding parts throughout the several views in the drawings.
Referring to the drawings in detail A designates generally a doorway or door frame which is of the conventional kind having a swinging door or doors B, only one in this instance being shown andfis pivotally mounted vertically for its swinging l movement by a bracket 10 having a base eXtension 11 secured at 12 to the door sill 13, the upper end of this bracket being formed with a pivot ear 14 in which is engaged ra pivot 15, the latter con-A 80 nected with a bearing plate 16 set in a notch or cut away portion 17 in the heel edge of the door B.
In axial alignment with the pivot 15 is a turning shaft 18 having the squared,y upper end 19 which fits in a corresponding opening 20 in a 85 coupling plate 21 mounted on the lower edge of the door B, so that on turning of this shaft the door will be caused to swing and in this manner the door moves to open and closed positions.
The shaft 18 is vertically journaled in a suitable bearing 22 vmounted in the base sill `23 of the doorway or frame and extends beneath the flooring 24 for such sill. Loosely engaged `on this' shaft 18 below the iiooring is a stirrup 25 having a yokeV 26 formed with upper and lower guides or loops 27 and 28, respectively. The lower end of the shaft 18 has fixed thereto the lower L- bracket 29 while xed to the bottom face of the liooring 24 is the upper L-bracket 30, the latter being held stationary in alignment with the doorway Aror base sill23. Thelower bracket 29 turns with the shaft 18. Y
s Carried by the stirrup 25 on opposite sides of its axis of movement and extending through the guides or loops 27 and 28 are abutment rods `31, these being vertical and parallel with said shaft 18. Active upon the rods 31 are plungers 33, each having the forked head 34 provided with notches 32, the latter serving as seats for the rods 31. The stems 35 of the plungers 33 are slidable in the respective brackets 29 and Si). The heads 34 are tensioned by the expansion springs 35 which surround said stems for maintaining the heads in contacting engagement with the rods 3l, so thatJ when the door is moved to opening position the same will be tensioned for the swinging thereof closed. The heads E are guided in the guides or loops 27 and 23 and when the door B is closed these heads engage both rods 31 to sustain the door in this normal position.
Spaeed from the shaft i8 and depending from the bottom face of the flooring 24 are inverted U-shaped hangers 37, these being set at an angle to converge toward the doorway A.
Vertically slidable through the flooring 24 close to the hangers 37 are foot actuated pedals 38, these being outside and inside with respect to the door B and its door frame A, the posts 39 of these pedals are vertical and slidably fitted in guides 4() on the hangers 37. Operated by each post 39 is a throw rod 41 which has connection with an arm 42 of a rocking shaft 43 journaled horizontally in the companion hanger 37. This shaft 43 has a crank arm 44 pivotally connected with a link 45 which latter is pivoted to the lower end of the post 3g next thereto. The rods 41 are also pivoted to a latching extension 46 of the stirrup 25.
The lowermostvplunger 33 tensions the door B when pushed by hand to opening position by the forked head 34 eocentrioally acting against either rod 3l in the yoke 2S of the stirrup 25. It will be obvious that when the door B is opened by hand 4the stirrup 25 will not turn with the shaft 18 and the tension of the lower plunger 83 returns the door toclosing position.
l The upper plunger 33 tensions the door B when the same is foot actuated for the opening of said door, and in this manrer the latter will return to normal closing position. The upper plunger 3 operates identically to the lower plunger when the stirrup 25 is turned, the latter being held xed to the shaft '18 by the lower plunger at this time, so that said shaft turns with the stirrup for the openingof the door during the actuation of either of the pedals 38.
The door B when swung to full opening position on operation of either foot pedal 33V will. be momentarily arrested through the medium of a latching bail 47 horizontally disposed and pivoted at 48 in bearings 49, which latter are fixed to the bottom faoe of the flooring 24 and such bail is tensioned by retractile springs 50 to urge it into contact with the latching extension 45 so that the latter when the door is being opened will engage in either seat 51 in the bail whereby such door B-will be momentarily held in opening position. The shaft 18 above the arm 46 has fixed thereto a striker 52 which is adapted for engaging with trip projections 53 formed on and rising from the bail` 47 close to the bearings 49 therefor, so that subsequent to the latching of the door by the bail 47 it will be automatically released and returned to closing position. The tension of the plungersBB is such that the instant the stirrup 25 is released it will have a quick swing so as not to be relatched by the bail 47.
What is claimed is:
1. The combination with a swinging closure, of
a rotatable shaft fixed to the closure for the swinging thereof, a stirrup loose on the shaft, means movable with the shaft and working in the stirrup to tension the closure for closing movement of the same when hand opened, foot operated means connected with the stirrup to move the same for the automatic opening of the closure and means working in the stirrup to tension the closure for closing movement when the stirrup` has been moved.
