FIGURE 11 is an enlarged perspective view of the stop illustrated in FIGURE 9; and
FIGURE 12 is a view of the thumb screw with the cap, which fits on the end, shown in perspective.
Referring now particularly to FIGURES 1 through 3 of the drawings, one or more of the stops 20 embodying the invention may be used to lock a closure, such as the movable window sash 21, in its fully closed position in its window frame 22, or as shown in FIGURE 1, to limit its movement in the window frame toward its fully open position so that the window will provide only a small ventilation opening 23 and will prevent unauthorized entry through the window or prevent children or pets from moving through the window opening into or from a room.
The usual rectangular window frame 22 formed of extruded aluminum side members 24 and top and bottom members 27 is rigidly secured in a suitable window aperture provided in a wall W of a building structure. A top window pane assembly 30 is rigidly secured in the upper portion of the window frame with its outer side edges extending into suitable inwardly opening channels or grooves 31 of the window frame and may include plastic glaze members 33 holding the panes of glass in place.
The side frame members 24 also have inwardly opening channels or vertical grooves 35 defined by vertical parallel flanges .37 and 38 in which are received the opposite vertical side portions 41 of the frame of the movable window sash 21. The window frame members 24 may also have middle vertical guide flanges 44 which are received in grooves 45 of the side sash frame portions 41.
As clearly seen in FIGURE 3, the inner guide flange 38 extends inwardly of the inner surface of the wall W and the stop 20 is rigidly secured to the inner guide flange 38 at a desired location thereon to limit upward opening movement of the movable window sash 21. The stop 20 includes a channel shaped body having inner and outer planar parallel sides 51 and 52, respectively, which are connected by and integral with a web 53. Pads 54 and 55, of a plastic or other suitable substance, preferably resilient, are adhesively secured or bonded to the sides 51 and 52, respectively, of the stop body. The pads 54 and 55 cover the internal surfaces of the sides of the stop body and thus prevent them from engaging the guide flange 38 when the stop is secured thereto. The inner side 51 of the stop body has a threaded bore 55a which extends at an angle outwardly and away from the edge of the inner side so that when the shank 56 of a thumb screw S is threaded therein, the head or thumb portion 57 thereof is disposed outwardly of the wall W and will not engage the wall when the thumb screw is rotated during the installation or removal of the stop.
The inner end of the thumb screw S, as illustrated in FIGURE 12, preferably is provided with a domed shaped end piece or cap 59 which may be formed of steel powder particles mixed with an epoxy cement and secured to the usual flat end 60 of the thumb screw. Such cap may be secured thereto in any suitable manner. The caps are provided since the ends 60 of such screws usually have circular rims which would tend to bite through the pad 54 and into the outer surface of the guide flange 38.
It will be apparent that when the screw 57 is threaded into the bore 55a, it will cause the inner pad 55 to be compressed against the outer side of the guide flange 38 at a location substantially at the central horizontal plane of the stop body and located closer to the edge of the inner side 51 than to the web. As a result, if two stops are used to limit upward movement of the window sash, FIGURE 1, if an upward force is exerted on the sash, it tends to pivot the lower ends of the stops outwardly and the upper ends inwardly thus any such upward force exerted on the movable window sash will be translated into forces compressing the upper portions of the pads 55 and the lower portions of the pads 54 of the stops and causes the stops to be held with a greater frictional force against upward movement on the guide flanges. If only one stop is mounted on the flange of the window frame, it preferably is mounted on the left side frame member 24 so that if the movable window sash is capable of some pivotal movement within the window frame and its right side can be moved upwardly to some degree while its left side is held against upward movement by the stop, any force tending to pivot the sash will also tend to pivot the stop on the guide flange in a clockwise direction. Any relative movement between the screw and the stop thus caused will tend to move the screw further inwardly in the bore thus increasing the frictional force with which the stop is held on the guide flange.
In use, a stop 20 may be secured to either one or both of the vertical side window frame members 41 at any vertical position. For example, if the window is in its fully closed position one or more of the stops may be secured to the frame guide flanges to provide an added safety lock to the usual sash lock 61a. If it is desired that a ventilation opening 23 be provided by the window, which, however, will be too small for an intruder to enter into the uilding structure through such opening or which will be too small to permit a child or pet to fall out of the window, a stop 20 is secured to one of the side flange members and will then limit upward movement of the movable window sash. The stop is spaced a substantial distance above the aperture 23 so that an intruder will find it extremely difficult or impossible to reach the screw S through the narrow opening 23 and thus will be prevented from removing the stop.
Referring now to FIGURES 4 and 5, the stop 20a is similar in structure to the stop 20 and, accordingly, its elements have been provided with the same reference numerals, to which the subscript a has been added, as the corresponding elements of the stop 20. The stop 20a differs from the stop 20 in that the bottom and top portions 61 and 62 of its outer side 52 are bent outwardly to increase the distance to which the stop extends outwardly in the inner channel 35a of a window frame 22a having a wide channel or groove 35a so that the movable window sash 21a thereof is capable of a rather great lateral displacement. In this case, the sash could be moved outwardly from the frame a distance greater than the distance to which the stop 20 extends laterally into such channel. The
laterally outwardly extending portion 61 or 62 of the stop 50 extend outwardly a sufficient distance that even if the movable sash is moved laterally outwardly in the window frame the maximum possible distance, the sash during its upward movement will still engage such lateral portion 61 or 62 of the stop body.
It will be apparent, of course, that the portion 62 would be engaged by the sash if the stop were on the left side member of the window frame and the portion 61 would be engaged by the sash if the stop were on the right side member of the window frame.
Referring now to FIGURES 6, 7 and 8 of the drawings, the stop embodying the invention includes a body 71 having an inner side 72 and an outer side 73 which are connected by a web 74. The outer side of the stop body has a resilient pad 75 of plastic secured thereto as by an adhesive or bonding. The inner side has a longitudinal slot 76 extending longitudinally therethrough which opens to the groove defined by the side through the flanges 77 and 78. A pad 80 of a somewhat resilient substance, such as nylon or other plastic, is movably positioned in the slot 76 and has lateral flanges 81 and 82 which are engageable with the inner side flanges 77 and 78, respectively, to limit lateral inward movement of the pad 80. Longitudinal movement of the pad in the slot 76 is limited by the inner end of a screw 85 threaded in the bore 86 of the inner side which opens to the slot 76, the inner end portion of the screw being received in a lateral bore 87 of the pad. The body also has a lateral extension 90 which extends laterally outwardly of the outer side 73 and which has the same function as the laterally outwardly extending portions 61 and 62 of the stop body 20a.
It will be apparent that the stop 70 is securable to the flange of a window frame in the same manner as the stops 20 and 20a and functions in the same manner. The provision of the movable pad 80 permits the stop to be employed on window frames having guide flanges of more widely varying thickness than the stops 20 and 20a. If desired, the pad 80 could be formed of metal in which case a resilient pad, such as the pad 54, would be secured to its inner surface. The term pad as used herein is intended to cover both a pad 80 formed of a somewhat resilient substance, such as nylon, and also a pad formed of a metal body and provided with a resilient protective means on its surface.
Referring now to FIGURES 9 through 11, the stop 20b which is shown secured to a flange of a door frame 91 to limit opening movement of a sliding door 92 mounted in the door frame. The stop 20!: is similar to the stop 20 and its elements have been provided with the same reference numerals, to which the subscript a has been added, as the corresponding elements of the stop 20. The stop 20]) differs from the stop 20 principally having a body and the pads of greater length than those of the stop 20 and being provided with two screws Sb and Sc which are threaded in inclined bores on the inner side 51b of the stop body 50b. The screws are of greater length than the screw S of the stop 20 if the stop 20b is to be mounted on the middle guide flange 94 of the top member 95 of the door frame so that the heads of the screws will be positioned inwardly of the inner guide flange 96 of the door frame. It will be apparent that if two screws are used, the stop is held with a greater force against displacement on the flange 94.
It will be now apparent that any one of the described and illustrated stops embodying the invention may be secured to a horizontal flange of the frame in which a horizontally movable door or window to lock such door or window in its closed position or to limit the degree to which it may be opened. For example, as illustrated in FIGURE 9, the door may be partly opened so that pets may enter or leave a building structure while at the same time children are prevented from entering or leaving the building or intruders are prevented from entering the building.
It will now be apparent that a new and improved stop for closures which are mounted in frames for either vertical or horizontal movement therein has been illustrated and described which is easily and quickly securable to a guide flange of such frame and which prevents opening of the closure or limits the degree to which it may be opened no alteration or modification of the frame or of the closure is required.
It will further be seen that by providing protective pads, such as the pads 54 and 55, which are resilient and whose facing surfaces are spaced apart a distance substantially equal or slightly less than the thickness of the guide flange on which they are mounted, the mounting of the stop on such guide flanges is facilitated since the stop will tend to remain in any position it is placed thereon until the screw is tightened.
It will further be seen that if the pads 54 and 55 are spaced apart a distance greater than the thickness of a guide flange received therebetween, the screw may be rotated to cause its inner end to extend into the groove and thus move the portion of the pad 54 engaged thereby into frictional engagement with the guide flange to cause the stop to be held against movement on the guide flange.
It will further be seen that, only a single stop may be employed to prevent or limit the opening of a closure, or if desired, as illustrated in FIGURE 2, two stops secured to opposite sides of the closure frame may be employed for this purpose.
It will further be seen that each of the stops includes a channel shaped body formed of aluminum, a hard plastic or the like, and resilient or protective pads for preventing contact between the guide flange and the sides of the body and the screw.
The foregoing description of the invention is explanatory only, and changes in the details of the construction illustrated may be made by those skilled in the art, within the scope of the appended claims, without departing from the spirit of the invention.
What is claimed and desired to be secured by Letters Patent is:
1. A stop for a closure movable in a flange structure having a guide flange for guiding movement of the closure, said stop including: a channel shaped body having a web and parallel spaced inner and outer planar sides extending perpendicularly from said web, said body providing a groove in which a guide flange of a frame structure is receivable; planar resilient pads on said inner sides for preventing contact between said inner sides and a guide flange on which said stop is mountable; and [rotatable means movable on one of said inner sides for rigidly securing said body to a guide flange, one of said pads on said inner side preventing contact between said last mentioned means and a guide flange disposed in said groove, said body when secured to a guide flange of the frame structure being positioned in the path of movement of the closure toward open position and being engageable thereby to limit opening movement of the closure in the frame structure, said inner side having a threaded bore and said movable means including a screw in said bore, the inner end of said bore being closed by the pad on said inner side whereby said pad on said inner side prevents contact between the inner end of said screw and a guide flange on which the stop is mountable.
2. The stop of claim 1 wherein said bore extends angularly relative to said inner side to position the outer end of the screw remote from the edge of said inner side.
3. The stop of claim 1, wherein one of said outer sides has means extending laterally outwardly therefrom into the path of movement of the closure.
4. The stop of claim 1, wherein said pads are secured to and cover opposed facing surfaces of said inner sides of said body.
5. The stop of claim 1, wherein one of said inner sides has a longitudinal slot therethrough opening to said groove, one of said pads on said inner side having an inner and outer end with said inner end being movable into said groove, said pad and said inner side having coengageable means for limiting movement of said pad into said groove.
6. The stop of claim 5, wherein said outer end of said pad on said inner side has a bore, said screw having an inner end portion receivable in said bore of said pad.
7. The stop of claim 1, wherein said screw has a convex inner end.
8. The stop of claim 1, wherein one of said inner sides has a second threaded bore spaced longitudinally from said first mentioned threaded bore and a second screw in said second bore, the inner end of said second bore being closed by the pad on said inner side.
