HINGE FOR SWINGING WINDOWS Filed Feb. 23, 1961 EMTOK I l m QJTCH My kl gram I, I 7 nyvaw (A-no RNE United States Patent 3,117,351 HINGE FOR SWINGING WINDOWS Axel W. Ahlgren, Rockford, Ill., assignor to Amerock Corporation, Rockford, III., a corporation of Illinois Filed Feb. 23, 1961, Ser. No. 90,980 2 Claims. (1. 20-42) The invention relates to a hinge such as may be used to mount a casement window and relates more particularly to hinges of the type in which a shoe slides back and forth along a track in a frame as the window is opened and closed.
The general object of the present invention is to provide in a hinge of the above character a new and improved shoe which slides freely and easily along the track and has a long life in service use.
A more detailed object is to form the shoe with a wiper operable to clean the track in advance of the shoe thereby to remove dust or other grit which may have settled on the track and which otherwise would wear away the shoe.
Other objects and advantages of the invention will become apparent from the following detailed description taken in connection with the accompanying drawings, in which FIGURE 1 is a fragmentary plan view of a casement window mounted on a hinge incorporating the novel features of the present invention.
FIG. 2 is an enlarged perspective of the hinge shown in FIG. 1.
FIG. 3 is a fragmentary perspective view showing the novel shoe.
FIG. 4 is an enlarged fragmentary sectional view taken along the line 4-4 in FIG. 3.
FIG. 5 is a View similar to FIG. 4 but showing the shoe mounted on the track.
For purposes of illustration, the invention is shown in the drawings incorporated in a hinge 19 such as may be used for mounting a window of the casement type in which a sash 11 slides horizontally in a frame 12 and simultaneously swings about a vertical axis extending along a side edge 13 of the sash. The hinge connecting the sash to the frame for such movement comprises a bracket 14 extending along and fastened to the lower edge of the sash and a link 15 pivotally connected at one end to an end 18 of the bracket 14 by a pin 19 and pivotally mounted at the other end on a pin 20 fixed on the sill of the frame. A shoe 21 which is fulcrumed at 22 on the end of the bracket and which supports the latter on a boss 23 disposed around the fulcrum 22, slides along a bar 24 fastened on the sill by screws 25 to form a horizontal track 26.
With the foregoing arrangement, the window is opened to the position shown in phantom in FIG. 1 by sliding the shoe along the track toward the fixed pivot 20. The link 15 and the bracket 14 turn relative to each other about the pin 19 and the sash swings about the pivot 22 While sliding horizontally away from the frame 12. To facilitate opening and closing of the window, the shoe 21 is fast on a rack bar 28 slidable longitudinally along the track in a channel 29 (FIG. 2) formed integrally with the bar, the rack being driven back and forth by a hand crank 30 through suitable gearing 31.
In this instance, the shoe 21 comprises a rectangular plate 32 with one edge 32 embedded in the rack, and a block 33, preferably of rectangular cross-section, disposed between the track and the plate 31 and having a side 34 forming a bearing surface for sliding along the track. While the block 33 may be formed to extend across the width of the track, herein it is relatively narrow and disposed adjacent the edge 35 of the bar 24 thereby to avoid sliding contact with the heads of the screws 25. Pins 38 which may be formed integrally with the block and molded into holes in the plate secure the latter to the block.
The present invention contemplates a novel shoe 21 which slides freely and easily along the track 26 and has a long life in service use. To achieve these ends, the shoe is formed with a wiper 39 operable to clean the track in advance of the bearing surface 34 thereby to remove dust or other grit which may have settled on the track and reduce friction and wear on the bearing surface. Herein, the wiper 39 comprises a resiliently flexible finger preferably of substantially the same width as the block and secured at one end to the leading end 44 of the block at a point spaced above the bearing surface 34. The finger is inclined downwardly and away from the end of the block as illustrated in FIG. 4, and its free end 41 extends .past the plane of the bearing surface when the shoe is disassociated with the track. Therefore, :when the hinge is assembled the finger is bent away from the block as shown in FIG. 5, and stressed to urge the end 41 resiliently against the track. To prevent grit from riding under the finger, a knife edge 42 is formed on the end 41 as by a bevel 43. As the beveled surface 43 is worn away in service use, the resilience of the finger maintains the bevel in contact with the track, and the edge 42 formed by the bevel is substantially self-sharpening. Thus, the knife edge remains effective to clean the track.
In the present instance, similar wipers are disposed at each end of the block as shown in FIGS. 2 and 3, corresponding parts of the second Wiper 39' being indicated with primed reference numerals. In the interest of economy :and simplicity, the wipers preferably are formed integrally with the block 33 as by molding of a suitable plastic such as Delrin. As shown in FIG. 4, the fingers may be molded on the ends of the block adjacent the upper side thereof and are relatively narrow with substantially parallel sides, the inner sides being formed by the walls of notches 44 molded across each end of the block. While the angle of the bevel 43 is not critical, an angle of approximately 45 degrees with the plane of the bearing surface is preferred.
I claim as my invention:
1. In a hinge for mounting a casement window for sliding in a frame, the combination of a track paralleling the direction of sliding of the window, a plate supporting the window for movement along said track, a block disposed between said plate and said track with one side forming a bearing surface for sliding endwise on the track, said plate being secured to the opposite side of said block, resiliently flexible fingers formed integrally with said block at the opposite ends thereof, each of said fingers being secured at one end to said block at a point above said bearing surface with the free ends of the fingers resiliently urged against the track at each end of the block, and knife edges formed on said free ends to parallel said track and extend substantially across said bearing surface thereby to clean said track in advance of the surface as said block slides back and forth along the track.
2. In a hinge for mounting a casement Window for sliding in a frame, the combination of a track paralleling the direction of sliding of the Window, a plate supporting the window for movement along said track, a block disposed between said plate and said track with one side forming a bearing surface for sliding endWise on the track, said plate being secured to the opposite side of said block, a resilient- 1y flexible finger formed integrally With said block at one end thereof and connected to the block at a point above said bearing surface with the free end of the finger resil- 4 iently urged against the track, said block and said finger being formed of a resilient plastic material, and a knife edge formed on said free end to parallel said track and extend substantially across said bearing surface thereby to clean said track in advance of the surface as said block slides along the track.
