Definitions

  • This invention relates generally to latches, and more particularly concerns an inexpensive latch especially adapted for use with sliding-panel windows and the like.
  • Windows of the sliding panel variety are being increasingly adopted for use in vehicles such as mobile homes and in other structures. Such windows are light in weight. and do not necessarily require complex closing mechanisms such as those found in automobiles. The elimination of such closing mechanisms lowers the cost of the window, and provides at least small amounts of wall space, which may be at a premium in a vehicle home.
  • sliding-panel window devices utilize a pair of glass plates or panels with at least one panel being slidable upon a track past the other panel.
  • Such arrangement requires no window-receiving cavity in the surrounding wall structure and permits the wall interior to be filled with insulation. It is desirable, of course, to be able to maintain the movable panel in a closed and locked position.
  • Yet another object of the invention is to provide a latch mechanism having relatively few moving parts, all of which are stressed to only low degrees, thereby enchancing the long service life of the latch.
  • a further object is to provide a window latch for a sliding window or like structure which provides a solid operational feel during latch manipulation.
  • FIG. I is a perspective view showing a typical slidingpanel window utilizing the present novel latch device.
  • FIG. 2 is a sectional view taken substantially in the plane ofline 22 in FIG. 1 and showing the latch parts in a fully assembled position for retaining a movable window panel;
  • FIG. 3 is a sectional view similar to FIG. 2 but showing the latch parts as they appear during latch assemy;
  • FIG. 4 is a sectional view taken substantially in the plane of line 4-4 in FIG. 2;
  • FIG. 5 is a sectional view taken substantially in the plane of line 5-5 in FIG. 2;
  • FIG. 6 is a perspective view of the window latch swing arm and mounting platform members
  • FIG. 7 is a perspective view showing the latch bese element upon which the mounting platform is affixed
  • FIG. 8 is a perspective view showing, in exploded relationship, parts of a modified version of the latch and the window panel to which the latch is affixed;
  • FIG. 9 is a sectional view taken substantially in the plane of line 9-9 in FIG. 12;
  • FIG. 10 is a sectional view taken substantially in the plane of line 10-40 in FIG. 8;
  • FIG. II is a perspective view showing the modified latch in its assembled and latched position
  • FIG. 12 is a sectional view taken substantially in the plane of line 12-12 in FIG. 1];
  • FIG. 13 is a perspective view similar to FIG. 11 and showing another modification of the latch device.
  • FIG. 14 is a perspective view similar to FIG. 13 and showing yet another embodiment of the invention.
  • FIG. 1 there is shown a typical bipanel window 20 mounted by a frame 21 within a surrounding wall 22.
  • a relatively stationary window panel 23 is fixed within the frame 21, and a second window panel 24 is mounted for sliding motion between tracks 25.
  • the second window panel 24 is moved into general superinposition over the first window panel 23, ventilating breezes are admitted through the opened area.
  • a novel latch 30 is provided.
  • this latch may be considered to include a stationary base element 31 which is adapted for attachment to the movable window panel 24, and a latch member 32.
  • the base member 31 can be attached to the movable window panel 24 by adhesive 34, through-bolts (not shown), or other convenient means.
  • the latch includes only a few parts, and these parts are subjected to low stress forces.
  • the latch member 32 includes a stationary mounting platform 37 adapted for fixed attachment to the base 31, and a spring arm 38 hinged to the mounting platform 37.
  • the latch member 32 illustrated in FIGS. 1, 2, 3 and 5 can be formed as a single piece from any suitable plastic or other material; when formed of plastic, a thin ridge 40 integrally molded between the mounting platform 37 and swing arm 38 provides a living hinge or a thin web of material interconnecting the swing arm 38 and the mounting platform 37 for relative pivotal movement.
  • the latch member 32 is secured upon it.
  • this mounting is accomplished by base member tongues 43 and 44 which engage mating mounting platform grooves 45 and 46 respectively when the mounting platform 37 is slid over the base member 31.
  • the tongues and grooves are formed along the longitudinal edges 49 and 50 of each respective element to provide a maximized bearing area and a correspondingly secure fit.
  • base element 31 can be first positioned upon the window panel, and when the base securing adhesive 34 has dried and the base member has been firmly affixed in its desired position, the latch mounting platform 32 can be slid over the base 31.
  • the swing arm 32 is biased into the closed or latching position overlying the mounting platform 37 as shown in solid lines in FIG. 2.
  • this biasing action is produced by a cantilever spring member 52 formed as part of the base 31.
  • the swing arm 32 When the latch is assembled, the swing arm 32 is folded from the position shown in FIG. 3 into the position shown in FIG. 2 wherein the swing arm 32 overlaps the mounting platform 31 as illustrated. In such overlapping position, a hooked stop device 54, formed on an undersurface S of the swing arm 32, protrudes through an opening 56 formed in the mounting platform 37. As the mounting platform 37 and swing arm 38 are slid over the mounting base 31, the underside 58 of the spring member 52 engages a top side 59 of the hook stop 54 in an interengaging knuckle connection, as illustrated in FIG. 3. A tapered stud portion 61 lo cated adjacent the hook stop 54 provides a guiding action as the hook stop 54 moves through the mounting platform opening 56, and during subsequent latch operation. At an opposite end of the latch, a similar elongated tapered stud 62 fits through a mating hole 63 formed in the mounting platform 32 to provide a guiding action during both initial swing arm positioning and subsequent latch operation.
  • a lock spring 65 formed on the cantilever spring 52 engages an edge 66 of the hook member 54 to prevent the mounting platform 37 from sliding off the base member 31 in a retrograde direction.
  • the lock spring 65 is unitarily formed with the main biasing spring 52, and snaps into place as the end 66 of the hook 54 completes its passage over the lock spring 65.
  • a stop 67 or other structure is formed at one end of the mounting base 31 to prevent the mounting platform 37 from sliding off the base member 31 in a forward direction either during assembly or thereafter.
  • both the hook stop 54 and the cantilever spring 52 rotate upwardly, as can be envisioned from FIG. 2. This motion brings the spring 52 into a stop position against the stationary mounting platform 37, and halts further upward rotational motion of the hook stop 54 or swing arm 38.
  • FIGS. 8-14 An alternate embodiment of the invention is shown in FIGS. 8-14.
  • hooks 80 and 81 are formed to fit through respective holes 82 and 83 formed in the mounting platform 37. Tips 84 and 85 of the hooks engage the undersurface 86 of the mounting platform 37.
  • the hooks 80 and 81 are resilient, and thus bias the swing arm into its latching position.
  • the hooks 80 and 81 also provide a resilient stop action for the motion of the swing arm 38 when the tips 84 and 85 are pulled into a generally horizontal position underlying the mounting platform 37.
  • a guide pin 90 attached to the underside of the swing arm 38 is positioned to fit through a guide hole 91 formed in the mounting platform 37. This guide pin and hole help stabilize swing arm motion.
  • a modified form of the swing arm leg 71 is provided in the embodiment illustrated in FIGS. 8-12; this modified embodiment provides an undercut finger ledge 93 to assist in lifting the swing arm 38 and the attached fin ger 72 out of engagement with the mullion 73.
  • the swing arm 38 can be formed separately from the mounting platform 37 to simply bear upon and rotate about a mounting platform bearing surface 93.
  • leg 71 Yet another embodiment of the leg 71 is shown in FIG. 13.
  • a second leg 94 is affixed to the base 31 or mounting platform 37 which allows a pinching motion to be applied to the latch when latch operation is desired.
  • a latch for a multi-panel window or the like having a movable panel comprising; a stationary base element adapted for attachment to the movable panel, a latch member including a stationary mounting platform element attachably secured to said stationary base, a swing arm secured to said mounting platform for overlapping the mounting platform, hooked stop means mounted on the swing arm for engaging a stationary element of said stationary mounting platform to limit swinging motion of the swing arm relative to the stationary elements, and means interconnecting the swing arm and said stationary element to urge the spring arm into a locking position for engaging a fixed catch member.
  • a latch according to claim 1 including a biasing means forming a portion of said hooked stop means for engaging said stationary element to urge said swing arm into a closed position abuttingly overlying said platform.
  • a latch according to claim 1 including a biasing means connected to a stationary element for engaging said hooked stop means to urge said swing arm into a closed position abuttingly overlying said platform.
