This invention aims to provide a novel means whereby a closure, such as a window or door, may be operated easily, to swing through an arc of approximately 180 degrees. The invention aims to supply novel means for eiiecting the end stated, in a simple but effective manner, the device including few parts and being not likely to get out of order. Another object of the invention is to provide a device of the class described which will work smoothly and capable of being operated without appreciable eiiort.
It is within the province of the disclosure to improve generally and to enhance the utility of devices or" that type to which the present invention appertains.
With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrange-. ment of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying drawings:
Fig. 1 shows in top plan, a device constructed in accordance with the invention;
Fig. 2 is an elevation;
Fig. 3 is a top plan showing the window fully opened, operating parts being arranged accordingly;
Fig. 4 is a top plan showing the parts as they will appear when the window is closed;
Fig. 5 is a sectional view of the gear casing;
Fig. 6 is a bottom plan showing a portion of the track;
Fig. 7 is a section on the line l? of Fig. 1.
Fig. 8 is a transverse section taken through the track and a part of the lower hinge.
In the drawings, the numeral I marks a support, such as a window sill. The numeral 2 designates a closure, in the present instance a window. A track is secured to one side of the window 2 and is designated as a whole by the numeral 3. The track 3 includes a top plate 4, an outer side wall 5 and an inner side wall ii. The walls 5 and t are disposed at right angles to the top plate 4. The walls 5 and ii of the track 3 have longitudinal ribs l which project toward each other and define a slot 8. The track 3 is secured to the sides of the window 2 by attaching elements ll extended through the wall 5. The wall 5 is considerably wider than the wall 6, and, consequently, the
securing elements 9 may be mounted readily in place, as shown in Fig. 2.
Each hinge ill includes a foot i I, having a reduced extension 12, the foot being held on the sill l by securing elements It.
The complemental member of the hinge E8 includes an inverted L-shaped anchor i5, comprising a vertical side piece it and a top member I! supplied at its free edge with a short depending flange E8. The side piece it of the anchor I5 is connected to a flange 1! 9, which is reduced to form an extension 25], connected to the part I2 of the foot H by a pivot element 2!. The top member H of the anchor l5 engages above the top plate t of the track 3, the flange l8 extending downwardly and overlapping the inner side wall 6 of the track. The side piece it of the anchor overlaps the side wall 5 of the track 3 and is connected thereto by securing members 22, for example rivets.
A base 23 is mounted on the sill l and is in the form of a box-like housing, including a bottom 24, and upstanding marginal walls 25. On the walls 25 of the housing 23, a lid 26 is mounted. Securing elements 21, such as screws, pass downwardly through the lid 25 and through the bottom 24 of the housing 23, the securing elements entering the sill I.
The bottom 24 of the housing 23 has an upstanding hub 28. A pivot member 29 is provided, and is in the form of a screw, extended downwardly through the lid 26 of the housing 23 and threaded into the hub 28. A gear segment 30 is mounted to rotate on the pivot member 29, and rests on the hub 23. The gear segment 39 meshes with a worm 3 l The gear segment 30 is supplied with an upstandin hub 32, which, engaging the lid 26 of the housing 23, maintains the segment 30 in such a position that it will mesh with the worm 3 l. The worm 3! is carried by a horizontal shaft 32, mounted to rotate in one of the marginal walls 25 of the casing 23 and terminating in an operating member 33, such as a crank, disposed without the housing 23.
The numeral 3% designates an arm, provided at its inner end with an angularly disposed offset 35, formed integrally with, or otherwise connected to, the gear segment 39. The numeral 35 marks a link, having a downwardly offset portion 31, the adjacent end of the arm 3 5 being received between the offset portion and the lower edge of the side wall 5 of the track 3, as Figs. 2 and 7 will show. The arm 34 is pivoted at one end, as shown at Hill, to the intermediate portion of the link 36.
The numeral 38 designates a fixed shaft on the outer end of the link 36, a wheel being journaled on the shaft. The wheel includes a hub 39 and a disk-like head 40, the hub being received slidably in the slot 8 between the rib 1 of the track, and the head being received between the ribs 1 on the one hand, and the top plate 4 of the track 3 on the other hand. The shaft 38 and the wheel may be alluded to as a slide, mounted to move longitudinally of the track 3.
The numeral 4| refers to a radius rod, the word rod being employed merely as a convenient name for the part, and imposing no limitation. The outer end of the radius rod 4| is connected to the inner end of the link 36 by a pivot element 42. Specifically, the radius rod 4 is pivoted to the ofiset portion 31 of the link 36., The radius arm 4| has a curved end 43, which enters the' open side of the housing 23, the curved end being mounted to swing on a shaft, which may be a screw 44, extended downwardly through the lid 26 of the housing 23 and threaded into the bottom 24 of the housing. With a view to economizing material in the curved end 43 of the radius arm 4|, and in order to promote a proper working of the device, the curved end 43 is made as short as possible, the pivot member 29 and the pivot screw 44 being located in a straight line parallel to the outer edge of the lid 26 of the housing 23. The offset 35 of the arm 34 enables the arm to clear the corresponding marginal wall 25 of the housing 23 when the window is closed. When the window is closed, the arm 34 and the radius rod 4| lie in superposed relation, directly beneath the track 3.
In practical operation, when the shaft 32 is rotated by means of the crank 33, the worm 3| rotatesthe gear segment 30, and the arm 35 is caused to, swing. The angle between the radius rod 4| and the link 36 is altered. the wheel 39-40 moves lengthwise of the track 3, and the window 2 is opened or closed, depending upon the direction of the rotation that is imparted to the shaft 32. Figure 3 shows that the construction is such that the window 2 can be opened through an arc of 180 degrees.
By way of recapitulation, the opener and closer includes a support I, to which a closure 2 is hinged as shown at 2|. A link 36 is provided. A track 3 is carried by the closure 2, and a slide 40 at one end of the link 36 is mounted to reciprocate on the track 3. A pivot element 29 connects one end of the arm 34 to the support and a means 33 is provided for actuating the arm. A pivot element 44 mounts one end of the radius rod 4| on the support a pivot element connecting the intermediate portion of the link 36 to the opposite end of the arm 34. A pivot element 42 connects the opposite end of the radius arm 4| with the opposite end of the link 36. The pivot element 44 which mounts the radius arm 4| on the supportl is located inwardly of the pivot element 29 which mounts said one end of the arm 34 on the support I. The pivot elements I00, 42, 44 and 29 are so located with respect to each other, the relative lengths of the link 30, the radius rod 4| and the arm 34 are such, and the track 3 is of sufficient length, so that the closure 2 may be opened through an arc of degrees, the radius rod 4| extending across the arm 34 when the closure 2 is opened through the aforesaid arc. The radius rod 4| starts to move toward the aforesaid crossed relation with respect to the arm 34 as soon as the opening movement of the closure 2 is initiated.
Having thus described the invention, what is claimed is:
1. An opener and closer comprising a sill, a closure hinged for swinging movement above the sill, a box-like housing secured to the sill, the housing having an end wall and being open on its inner side, a shaft journaled in the housing and having a worm, a gear mounted to rotate in the housing and meshing with the worm, an arm joined fixedly at one end to the gear and extended out of the open side of the housing, a radius rod pivoted at one end in the housing and extended out of the open side thereof, a track secured to the closure, a link, a slide on one end of the link and mounted for reciprocation on the track, a pivot element connecting the opposite end of the link with the opposite end of the radius rod, and a pivot element connecting the opposite end of the arm with the intermediate portion of the link, the arm including an angularly extended part which enables the remainder of the arm to clear the end wall, when the closure is in closed position.
