Definitions

  • a cross shaped shaft extends through the housing and handle knobs are secured to the shaft, the knobs being journalled on housing parts.
  • a spring pressed latch plate on the door jamb normally holds the door closed and a plunger is mounted in the door between the shaft and the latch plate. Rotation of one of the handle knobs in either direction will operate the plunger to depress the latch plate and unlatch the door.
  • This invention relates to apparatus for latching a door and more particularly to mechanism for manually releasing an automatically operating latch bolt or the like.
  • latch sets presently in use are costly items to manufacture due in part to the complexity of the devices and the fact that many of the metal parts require precision machining and other finishing. Also the task of assembling the numerous parts which make up the conventional latch set is time consuming and this is reflected in the selling price of the manufacturer. The eventual purchaser of such a set is usually faced with the added expense of hiring a skilled workman to install the set in the door and with the current high cost of labour this factor must be given consideration by the average home owner.
  • the present invention is made almost entirely of plastic and the design of the apparatus is such that the several parts can be made by a relatively simple and inexpensive injection molding process. Such a process produces finished parts which can be distributed and sold without assembly to effect a corresponding reduction in the selling price of the apparatus.
  • the apparatus is one which can readily be installed by an unskilled householder or workman using simple tools and if certain errors are made in preparing the door to receive the device, the present apparatus will compensate for at least some of the miscalculations and still operate effectively thereafter.
  • a further feature of the invention resides in the provision of a shaft which requires only a small amount of plastic material to form but which possesses the strength and rigidity of the conventional metal shaft used in a latch set.
  • the shape of the plastic shaft is such that it can be threaded to receive the handle knobs, and said knobs can readily be keyed to the non-corrosive shaft.
  • Another advantage derived from the invention is the means whereby rotating parts of the apparatus are journalled in the door. No special bearings are required for this purpose and the ones provided by the design of the apparatus ensure proper alignment and function of the rotating parts. Since the bearing surfaces as well as other parts of the apparatus are formed of suitable plastic materials, no lubrication is required and the action of the device is exceptionally quiet and smooth operating.
  • the invention contemplates a housing which is mounted in the door 'ice near the free edge thereof.
  • a shaft extends transversely through the housing and the door and novel means is provided to journal the shaft in the housing.
  • the shaft has a number of radial ribs which are engaged by a yoke on the end of alatch operating plunger.
  • the shaft and the yoke have mating parts which interlock said shaft and yoke and also provide a cam action whereby rotation of the shaft in either direction will reciprocate the plunger.
  • FIGURE 1 is a sectional plan of the apparatus
  • FIGURE 2 is a view taken on the line 22 of FIG- URE 1,
  • FIGURE 3 is a view taken on the line 3-3 of FIG- URE 1,
  • FIGURE 4 is a view taken on the line 44 of FIG- UR'E 1,
  • FIGURE 5 is a view taken on the line 5-5 of FIG- URE 1,
  • FIGURE 6 is a view tatken on the line 66 of FIG- URE 5
  • FIGURE 7 is a view taken on the line 77 of FIG- URE 1, and
  • FIGURE 8 is a view taken on the line 8-8 of FIG- URE 4.
  • the numeral 10 indicates generally a door having an inside face 11, an outside face 12 and a side edge 14.
  • the door 10 closes against a jamb 16 of the door frame, the jambbeing fitted with an abutment strip 17.
  • the apparatus includes a keeper or latch plate 20 which is mounted in a supporting frame 21, the frame being inlaid into the edge of the jamb 16 with the right side edge of said frame aligned with the adjoining face of the strip 17, see FIG- URE 1.
  • the frame 21 is secured to the jamb by means of metal screws 22.
  • Plate 20 has integrally formed pintles 23 (FIGURE 2) at the corners of its upper and lower edges and these pintles are lodged in grooves 24 formed in the adjacent edges of the supporting frame opening 25.
  • the grooves 24 extend inwardly from the rear face of the frame 21 and terminate short of the exposed face of said frame.
  • the edge 26 of the plate 20 abuts the adjacent edge 27 of the frame 21 to limit inward movement of said latch plate.
  • the latch plate 20 is supported in upright position in the frame 21 by the pintles 23 and a spring 28 fitted to said plate normally urges the latch plate outwardly of the opening 25, the plate then being disposed at a slight angle to the outer edge of the door. Since the spring 28 is formed of a resilient plastic material, it conveniently can be molded as an integral part of the latch plate 20.
  • FIGURE 1 illustrates the manner in which the door 10 is prepared to receive the present apparatus.
  • a large hole 30 is bored transversely through the door from one face to the other at the same level as the latch plate 20.
  • a smaller hole 31 is drilled in the door edge 14, the axis of the hole 31 being normal to the edge 14 and intersecting the axis of the hole 30 at right angles.
  • the door edge 14 is then recessed as at 32 to receive a strike 34.
  • the strike 34 is secured within the recess 32 by metal screws 35, see FIGURE 5.
  • a hole 36 is provided in the strike 34 at mid-height, which hole registers with the hole 31 in the door.
  • the hole 36 communicates with a tapering recess 38 which is formed in the outer face of the strike 34 to receive the inclined latch plate 20.
  • the recess 38 provides a stop 39 against which the slightly rounded edge 40 of the plate 20 is adapted to bear to latch the door in closed position.
  • a housing 44 consisting of an outer sleeve 45 and an inner sleeve 46.
  • Sleeve 45 has an end flange 48 extending normal thereto and in which a central opening 49 is formed.
  • the outer face of the flange 48 is provided with a shallow depression 50 which is circular and concentric to the opening 49, the bottom of said depression being normal to sleeve 45. Threads 51 are cut on the inner surface of the sleeve 45.
  • the inner sleeve 46 is a relatively short member which is externally threaded as at 53 to engage the threads 51 of the outer sleeve.
  • Sleeve 46 has an end flange 54 extending normal thereto and which is provided with a central opening 55 extending through a concentric depression 56, the bottom of said depression being normal to sleeve 46.
  • the hole 30 is purposely made slightly larger than the outside diameter of the sleeve 45 and that no particular care need be taken to ensure that the axis of said hole is truly perpendicular to the faces 11 and 12 of the door.
  • the sleeves 45 and 46 are threaded together, their respective flanges 48 and 54 are moved into clamping engagement with the door faces. This has the effect of aligning the housing so that the housing axis is normal to the door faces regardless of the relative position of the axis of the hole 30 or the fact that the periphery of the hole may be uneven.
  • the housing sleeves are tightened by hand, vis. no special tool is used for this purpose.
  • the plastic flanges 48 and 54 have a natural tendency to cling or adhere to the wood of the door and a much greater hand pressure must be exerted in order to separate the sleeves.
  • said sleeve 45 is provided with a radially projecting lug 58, see FIGURES 1 and 7, which bites into the wood of the door when the two sleeves are finally tightened.
  • the self-aligning and self-locking housing 44 does not require the usual screws or other fasteners to secure it to the door.
  • the same housing and its associated parts may be used on doors of varying thicknesses with the same results, for example, it could be adjusted to fit doors of up to about 3 inches in thickness.
  • a shaft 60 Extending through the openings 49 and 55 is a shaft 60 having radial ribs 61.
  • the ribs 61 extend from end to end of the shaft and preferably, four such ribs are provided at 90 intervals about the shaft circumference so that said shaft is seen as a cross when viewed in end elevation.
  • a plastic shaft 60 of the described shape has ample rigidity and strength for the purpose it serves in the apparatus.
  • the outer edges of the ribs 61 are radiused about the longitudinal axis of the shaft and formed on these edges at each end of said shaft is an interrupted thread 63.
  • Two of the ribs 61 are vertically disposed above and below the shaft 60. These two vertical ribs are offset intermediate their length to provide notches 64. As viewed in FIGURE 5, the notches 64 open out from the right side of the shaft 60 and the horizontal rib on the same side has a notch 65 which is aligned with the notches 64. As shown best in FIGURES and 6, the outer sleeve 45 of the housing has a hole 68 and the sleeve 46 has a cut out 69 registering with the holes 31 and 36, and projecting throungh these aligned holes and cut out is a cylindrical plunger 70. The plunger 70 has a rounded outer end 71 which projects into the recess 38 in the strike 34.
  • Interconnecting means is provided between the inner end of the plunger and the shaft.
  • a yoke 72 is integrally formed on the inner end of the plunger.
  • the yoke 72 has inwardly projecting arms 73 which extend over the vertical ribs 61, and between these two arms the inner edge of the yoke is recessed as shown at 74 in FIGURE 5.
  • the recess 74 has substantially the same shape as the cross sectional profile of the adjoining portions of the shaft 60 at notches 64 and 65 into which yoke 72 fits.
  • the yoke is a loose fit on the shaft 60 but is prevented from moving endwise of the shaft by the notches 64 and 65 on the ribs, thus the yoke is self-aligning.
  • a spring 76 encloses the plunger 70 between the strike 34 and yoke 72. Rotation of the shaft 60 in either direction will cause the plunger 70 to move endwise and compress spring 76.
  • knobs 80 and 81 Mounted on the ends of the shaft 60 are handle means in the form of handle knobs 80 and 81.
  • the left or inside knob 80 has a peripheral wall 83 which tapers inwardly to a base 84.
  • the base 84 has a suitably threaded opening 85 which enables the knob to be threaded on to interrupted threads 63 on the end of the shaft 60.
  • Knob 80 is received in the shallow depression 50 on the flange 48.
  • the right or outside knob 81 which has a similar wall 87 and base 88 provided with a threaded opening 89, is similarly lodged in the depression 56 of the inner sleeve flange 54 when said knob is threaded on shaft 60.
  • Shaft 60 has a diameter considerably smaller than the openings 49 and 55 through which it projects.
  • the depressions 50 and S6 serve as thrust hearings in which the handle knobs, and the shaft supported thereby, are rotatively mounted.
  • the bases 84 and 88 in depressions 50 and 56 act as means for rotatably supporting the shaft in housing 44.
  • the flanges on the sleeves 45 and 46 and the bottoms of depressions 50 and 56 are parallel to the faces 11 and 12 of the door.
  • the axis of the shaft 60 is therefore normal to the door faces and the several parts are properly related to one another even if the door is slightly warped or the opening 30 is inaccurately bored. Since the plastic knobs have sliding contact with the plastic housing, a particularly quiet and smooth acting hearing is provided which does not require lubrication.
  • the outer handle knob 81 is non-rotatably secured to the shaft 60 by means of a key 90, see FIGURES l and 3, which key is square in cross section.
  • a notch 91 shown in FIGURE 3 only, is cut into the threads of the opening 89 in the knob 81.
  • the cross sectional dimensions of the key are such that said key will snugly fit between two adjacent ribs 61 on the shaft with one edge of the key entering the notch 91.
  • the key 90 may be inserted in this manner by pressure applied by hand. When the key 90 is so inserted, the handle knob 81 cannot be moved relative to the shaft 60.
  • FIGURES l and 7 show the means of securing the inner handle knob 80 to the opposite end of the shaft 60.
  • a lock washer 93 is used for this purpose, the washer having a cross-shaped opening 94 which conforms to the cross sectional shape of the shaft 60.
  • a number of circumferentially spaced and inwardly projecting tabs 95 are provided on the outer edge of the washer 93.
  • the base 84 of the handle knob has a similar number of slots 96 of corresponding shape and spacing.
  • the lock washer 93 fits over the end of the shaft and seats against the base 84 with the tabs 95 lodged in the slots 96.
  • the outer face of the washer 93 is provided with a pair of small handles 97 by which the locking device may be inserted into the handle knob or removed therefrom.
  • the knob '80 is thus nonrotatably secured to the shaft 60 and may be adjusted lengthwise thereof, with the Washer 93 enabling the knob to be locked in a number of selected positions on the shaft.
  • the numeral 101 indicates a pin which is integrally formed on the base 84 of the inner handle knob 80 to project inwardly therefrom parallel to the axis of the shaft 60.
  • An arcuate slot 102 is formed in the depressed portion of the flange 48 and the pin 101 extends into this slot.
  • the pin 101 is centrally located in the slot 102 as shown in FIGURE 4, and travel of the pin in a circular path obviously is limited by the length of the arcuate slot.
  • the shaft 60, and the knobs 80 and 81, keyed thereto can be turned only a limited amount in either direction. Because of the limited rotation of the shaft 60, the plunger 70 cannot be projected far enough beyond the door edge 14 so that, when the door is closed, the end 71 of said plunger will strike the inner face of the door jamb 16.
  • the hollow handle knobs 80 and 81 are closed by means of covers or discs 104 and 105.
  • the numerals 106 and 107 indicate rebates which are provided on the outer edges of the walls 83 and 87 to receive these discs.
  • the discs 104 and 105 are made so that their exposed faces are slightly convex as shown in dotted lines and while in this position said discs are inserted into the snug fitting rebates 106 and 107.
  • finger pressure is applied to the centres of the discs they snap inwardly whereupon their exposed faces are slightly concave.
  • the discs are securely attached to handle knobs and can only be removed by means of a tool having a point which can be entered into holes, not shown, which are formed in the discs for this specific purpose.
  • the plastic parts do not corrode so that there is no likelihood of the apparatus sticking or becoming inoperative due to a build up of rust as sometimes does happen with latch sets constructed of metal.
  • the exposed portions of the device can be produced in a wide variety of colors which will last indefinitely.
  • the elimination of metal bearing surfaces results in a door latch apparatus which is quiet, very smooth working and practically free from wear. This was proven by a test conducted to measure the wearing properties of the various parts of the apparatus. In this test, the apparatus was connected to a motor driven apparatus which repeatedly unlatched the door, opened it, then closed and relatched the door. These movements were conducted at a frequency of approximately 100 times per minute over an extended period of time at the end of which no appreciable signs of wear were detected in the apparatus.
  • the transfer of manual pressure to release the lock is effected by compression contacts of several surfaces which are generous in area, so reducing unit pressures. Most of these contacts are of a rolling nature and only one is a sliding contact. These features account partly for the freedom from wear. The balance is accounted for in the choice of plastic material used, which by its nature is more elastic and more wear resistant than many metals.
