DESCRIPTION

As shown in FIG. 1A, the present latch apparatus is indicated by reference number 10. Latch apparatus 10 includes a housing 12, a latch 14, and a lever 16. The lever 16 pivots or swings between closed and open positions. The solid lead lines show a closed position for the lever 16 and latch 14. The dashed or phantom lead lines show an open position for the lever 16 and the latch 14. When the lever 16 is pivoted up, then the latch 14 is drawn in. When the lever is pivoted down, then the latch 14 is drawn out.

FIG. 1B shows the latch apparatus 10 on a gated barrier 18. Gated barrier 18 includes a frame 20 and a gate 22 within the frame 20. Frame 20 is a U-shaped open top frame. Frame 20 includes a left standard 24, a right standard 26, and a lower horizontal support 28 or threshold 28 between the standards 24, 26. A frame extension 30 is engaged to the left side of the frame 20. Disposed between the frame 20 and a vertical environmental object such as a door jamb or wall to the right of the frame 20 and disposed between the frame extension 30 and a vertical environmental object such as a door jamb or wall to the left of the frame extension 30, is a set of four frame-to-wall connectors 32. Connectors 32 include a threaded shaft 34, a hand wheel 36 threadingly engaged on the shaft 34, and a wall cup 38 for engaging the vertical environmental object such as a door jamb or wall. The wall cup 38 is fixable to the door jamb or wall by a pin connector 40 such as a screw. Hidden from sight is a rotatable disk on the end of the shaft 34 that is received by the wall cup 38. The threaded shaft 34 may or may not be threadingly engaged with a respective corner portion 42, 44, 46, 48 of the frame 20 and frame extension 30. Preferably the threaded shaft 34 slides into and out of its respective corner portion 42, 44, 46, 48 without being threadingly engaged. The frame 20 and frame extension 30 hold the gated barrier 18 in place, and optionally off the floor, by the hand wheel 36 being turned so as to increase the effective distance of the shaft 34 between the hand wheel 36 and the disk in the wall cup 38. The hand wheel 36 abuts the corner portion 42, 44, 46, 48 and the disk abuts the wall cup 38 that is engaged to the door jamb or wall. When such effective distance is increased, one result is to pressurize the frame 20 and frame extension 30. In other words, one or more of the standards 24, 26 are manufactured to be oblique relative to the lower horizontal support 28. However, when the frame 20 and frame extension 30 are pressurized by increasing such effective distance, such one or more standards 24, 26 are drawn into a right angle relationship with the lower horizontal support 28, thereby drawing the upper portion of standard 26 into engagement with the latch 14 of the latch apparatus 10.

The gate 22 includes outer or end support members 50, 52. End support member 52 defines the pivot axis of the gate 22. Gate 22 further includes an upper horizontal or transverse support member 54 and a lower horizontal or transverse support member 56. Gate 22 further includes, disposed between end support member 50, 52, a set of vertical support members 58, 60, 62, 64, and 66 that extend from the lower horizontal support member 56 to the upper horizontal support member 54. Vertical support members 50, 58, and 60 extend into the latch apparatus 10 and are engaged to the upper horizontal support member 54. In FIG. 1A, the latch apparatus 10 is closed and the gate 22 is closed.

FIG. 2A shows a front view of the latch apparatus 10. Latch apparatus 10 includes a spring loaded slide lock 68. Slide lock 68 is mounted on the upper horizontal member 54 of gate 22. An internally mounted spring 70, shown in FIGS. 9A, 9B, 9C, and 9D, biases the slide lock 68 toward the housing 12. Slide lock 68 includes a main body 72 and a ledge 74 extending from the main body 72. Ledge 74 extends in the direction of the housing 12. Ledge 74 includes an oblique upper portion that extends downwardly and toward the latch apparatus 18 such that the lever 16 can snap back into a locking relationship with the slide lock 68.

Lever 16 swings or pivots on a pivot pin 76. Pivot pin 76 engages the housing 12, further engages the latch 14, and further engages the gate upper horizontal support member 54. Pivot pin 76 is secured to the latch apparatus 16 by a lock washer or clip 77.

Latch 14 includes a latch head 78. Latch head 78 includes a U-shape that includes a first longer extension 80 and a second shorter extension 82. Latch head longer extension 80 is shown in FIGS. 2A and 2B. Latch head shorter extension 82 is shown in FIGS. 2C and 2D.

Latch 14 is closed in FIGS. 2A and 2C. Latch 14 is open in FIGS. 2B and 2D.

In each of the closed and open positions as shown in FIGS. 2A and 2B, the first extension 80 of the latch head 78 extends over a portion of the frame 20, including over a portion of standard 26 and frame corner portion 42. This shows that gate 22 is a one way gate. Whether the lever 16 is closed as shown in FIG. 2A or open as shown in FIG. 2B, the first extension 80 of the latch head 78 extends over a portion of the frame 20. Gate 22 swings only one way, with this one way being toward the viewer in FIG. 2B and away from the viewer in FIG. 2D.

FIGS. 2C and 2D show the latch head extension 82. In the closed position of FIG. 2C where the lever 16 is closed, the latch head extension 82 extends over a portion of the frame 20, including over a portion of standard 26 and frame corner portion 42 such that the gate 22 cannot swing. In the open position of FIG. 2D where the lever 16 is open, the latch head extension 82 has been drawn inwardly such that a distal vertical edge of the latch head extension 82 has been drawn away from an inner edge of frame standard 26 and frame corner portion 42.

In FIG. 3A the U-shaped latch head 78 extends to each side of the standard 26 such that latch head extension 80 extends over one side or face of the standard 26 and such that latch head extension 82 extends over the other side or face of the standard 26. Here the lever 16 is closed and the proximal end of the second action lever 16 is locked by the ledge 74 of the first action slide lock 68.

In FIG. 3B the latch head extension 82 is withdrawn from its respective face of the standard 26 when the lever 16 is pivoted to an open position, after the slide lock 68 has been slid away from the proximal end of the lever 16. Here, where the lever 16 has been pivoted to an open position, the latch head extension 80 still extends over a portion of the standard 26 such that the gate 22 swings only one way, which way is toward the face of the standard 26 over which the latch head extension 80 extends. The latch head extension 80 extends over such face of the standard 26 when the lever 16 is pivoted to the open position and when the lever 16 is pivoted to the closed position and when the gate 22 is in the closed position.

In FIGS. 3A and 3B, it can be seen that the lever 16 includes a top 86, a first side 88, and a second side 90. Sides 88, 90 are generally triangular shaped. Top 86 is curved. Sides 88, 90 extend forwardly of a distal edge 258 of the top 86. The distance between the inner faces of sides 88, 90 is greater than the distance between the outer faces of the latch head 78 such that latch head 78 is disposed within the latch sides 88, 90.

FIGS. 4A and 4B show the latch apparatus 10 from a perspective different from the perspective of FIGS. 3A and 3B. In FIG. 4A the lever 16 is closed and the gate 22 is closed, with the latch head 78 engaging the standard 26. In FIG. 4B the lever 16 has been pivoted to the open position where latch head extension 80 is engaged with the standard 26 and where latch head extension 82 is disengaged from the standard 26.

FIGS. 5A and 5B show top views of the closed and open positons of the lever 16. Latch head 78, which includes a distal U-shaped portion and is H-shaped as a whole, includes a base 92. When each of the latch head extensions 80, 82 are engaged with standard 96, as shown in FIG. 5A, latch head base 92 confronts the inner face 94 of the standard 26. When latch head extension 82 is disengaged from standard 96, latch head base 92 is spaced from the inside face 94 of standard 26, as shown in FIG. 5B.

The bottom of each of the oblique channels 224, 226 is distal relative to the latch neck 134 and spaced from its respective stepped edge 216, 218. The top of each of the oblique channels 224, 226 is adjacent to a top 228 of the latch head 78. The bottom of each of the oblique channels 224, 226 is adjacent to a bottom 230 of the latch head 78. Bottom 230 is shown in FIGS. 9A, 9B, 9C, and 9D. Channel 224 engages first peg 208 of lever side 88. Channel 226 engages first peg 208 of lever side 90. Stepped edge 216 engages second peg 210 of lever side 88. Stepped edge 218 engages second peg 210 of lever side 90. The first peg 208 is disposed distally of the second peg 210 when the lever 16 is in each of the closed and open positions. The first peg 210 is disposed at a greater altitude than the second peg 210 when the lever 16 is in each of the closed and open positions. As the lever 16 moves between the closed and open positions, different surface portions of the pegs 208, 210 continually engage different surface portions of the oblique channels 224, 226 and the stepped edges 216, 218.

Latch head extension 80 includes a pair of horizontal upper and lower channels 232, 234 that open distally on the vertical edge 220 and that are closed with an oblique edge proximally. Latch head extension 82 includes a pair of horizontal upper and lower channels 236, 238 that open distally on the vertical edge 222 and that are closed with an oblique edge proximally. Such proximal edges disposed at the closed end of the channels 232, 234, 236, 238 run parallel to the axis of the oblique channels 224, 226.

Latch neck 134 includes a pair of horizontal slots 240, 242. Slot 240 is formed in latch side 200. Slot 242 is formed in latch side 202. Slots 240, 242 are aligned and extend horizontally. Gate upper horizontal support member 54 includes a pivot opening 244, shown in FIGS. 9A, 9B, 9C, and 9D, in each of the sides of the tubular gate upper horizontal support member 54. Pivot opening 244 receives pivot pin 76. Pivot openings 244 are aligned with slots 240, 242.

Latch head 78 is H-shaped such that a base 92 ties the longer latch head extension 80 to the shorter latch head extension 82. The distal face of base 92 includes upper, lower, and intermediate horizontal ribs projecting distally from base 92, as shown in FIG. 14C. The proximal face of base 92 is a stop that stops against the distal end of gate upper horizontal support member 54 when the latch 14 is drawn in by the lever 16.

The height of the latch neck 134 is greater than the height of the latch head 78 whether the height of the latch neck 134 is measured 1) between latch neck top 172 and any of the distal latch edge portions 196, 198 or 2) between latch neck top 172 and any of the proximal latch edge portions 201, 203.

Slide lock 68 is spring biased. Slide lock 68 includes a slide pin 246 engaged with the slide lock main body 72 and further slidingly engaged in aligned slots 248 formed in each of the sides of the gate upper horizontal support member 54. Slide lock 68 includes the coil spring 70 having a proximal end engaged to slide pin 246 and a distal end engaged to pivot pin 76. Slide lock 68 is thus continually biased in the distal direction so as to keep the ledge 74 biased toward the locked position. Ledge 74 includes an upper tapered edge and the proximal end of lever 16 includes a lower edge oppositely tapered such that lever 16 can snap by the tapered edge of ledge 74 and into its closed position even when slide lock 68 is in its closed position.

In operation, as shown in FIG. 9A, lever 16 is in a closed position and slide lock 68 is in a closed position. Latch head 78 is in the closed position where the latch head 78 engages the frame 20, namely, the standard 26 and the frame corner portion 42. Lever 16 is locked under the ledge 74 of the slide lock 68. First pegs 208 are in the upper ends of oblique channels 224, 226. Second pegs 210 are engaging the stepped base edges 216, 218 near the steps of the stepped base edges 216, 218. Latch neck 134, integral with latch head 78, is in the distal position, with the pivot pin 76 in the proximal end of slots 240, 242. FIG. 9B shows the slide lock 68 having been slid proximally, which is the first independent mechanical step that must be performed prior to swinging open the gate 22. When the slide lock 68 is slid in the proximal direction, the coil spring 70 is drawn to a greater pressure. FIG. 9C shows that the lever 16 has been pivoted from the closed position to an intermediate position. Slide lock 68 has been released and has been automatically returned to its closed position by the coil spring 70 pulling on the slide pin 246. As the lever 16 is pivoted, the first pegs 208 and the second pegs 210 travel in an arc about the pivot pin 76 and the first pegs 208, by engaging the oblique channels 224, 226, draw the latch 14 proximally and away from the standard 26 and frame corner portion 42. Latch neck 134 is guided as it is drawn proximally along a straight axis by the gate upper horizontal support member 54 on which the latch neck 134 rides, by the internal supports of the housing 12, by the slots 240, 242 riding on the pivot pin 76, by the portions of the housing 12 that form opening 132. Latch head 78, and thus its integral latch neck 134, is stabilized against wobble by the second pegs 210 continually engaging the stepped edges 216, 218 from the closed position of the lever 16 to the intermediate position of the lever 16 shown in FIG. 9C and to the fully open position of the lever 16 shown in FIG. 9D, which is completion of the second independent mechanical step that must be performed prior to swinging open the gate 22. In FIG. 9D, the slide lock 68 remains closed, the lever 16 has been fully opened, the first pegs 208 are in the bottom ends of the oblique channels 224, 226, the pivot pin 76 is adjacent to the distal end of slots 240, 242, the base 92 is at the distal end of the gate upper horizontal support member 54, the shorter extension 82 has cleared the inner faces of the standard 26 and the frame corner portion 42, and the longer extension 80 remains extended over the front faces of the standard 26 and frame corner portion 42 such that the gate 22 is swingable toward the front of the gated barrier 18 and is not swingable in the other direction.

In operation, to close the gate 22, the lever 16 is maintained in its open position. Lever 16 is maintained in its position by a friction fit between latch neck 134 and the gate upper horizontal support member 54, by a friction fit between latch neck 134 and the internal supports of the housing 12, and by a friction fit between the sides 88, 90 of the lever 16 and the sides 102, 106 of the housing 12. If an attempt to close the gate 22 is made when the lever 16 is in its closed and locked position engaged under the slide lock ledge 74, the outer face of the latch head extension 82 will hit the front faces of the standard 26 and frame corner portion 42. After gate 22 is closed with the latch head 78 in the proximal position such that shorter latch head extension 82 has bypassed the standard 26 and frame corner portion 42 and such that the inner face of latch head extension 80 extends over the front faces of the standard 26 and frame corner portion 42, the lever 16 is closed. As lever 16 is closed, the first pegs 208 travel in an arc about pivot pin 76 as first pegs 208 engage oblique channels 224, 226, thereby drawing the latch 14 distally and sliding the shorter latch head extension 82 over the rear faces of the standard 26 and frame corner portion 42 so as to lock the gate 22 to the frame 20. As the latch 14 is drawn distally, the second pegs 210 travel in an arc about pivot pin 76 and stabilize the latch head 78 and latch 14 as a whole.

As shown in FIGS. 10A and 10B, the oblong depressions 250, 252 in the housing sides 102, 106 receive name plates for the name of the company marketing the latch apparatus 10 or for the name of the particular latch apparatus. FIG. 10A shows the bevel or taper of the proximal beveled edge 254 of the proximal end 204 of the lever 16. Beveled edge 254 is also shown in FIGS. 9A, 9B, 9C, and 9D. FIG. 10B shows that housing extensions 128, 130 cover up, when the latch 14 is withdrawn by the lever 16, a pair of spaces 256 that are formed when the latch head 78 transitions to the latch neck 134 so as to minimize pinching of fingers or the skin of fingers. FIG. 10B shows that the distance between the inner faces of the sides 88, 90 of the lever 16 is greater than the distance between the outer faces of the latch head extensions 80, 82. FIG. 10B shows a front edge 258 of the top 86 of the lever 16. Front edge 258 is straight and runs to and between lever sides 88, 90. Front edge 258 is a stop that stops the lever 16 from further pivoting when front stop edge 258 when the front stop edge 258 abuts the extensions 128, 130 as shown in FIG. 9D. A further stop to the pivoting is an abutment of the first pegs 208 with the bottom ends of the oblique channels 224, 226. A further stop is provided by base 92 hitting the distal end of the gate upper horizontal support member 54.

FIGS. 11A and 11B show that, while the distal portion of the latch head 78 is U-shaped, the latch head 78 as a whole is H-shaped. FIGS. 11A and 11B show that extensions 80, 82 extend both proximally and distally of the latch head base 92. Latch neck 134 extends into the latch head 78 between the proximal portions of extensions 80, 82. Latch neck 134 is integrally connected with inner faces of proximal portions of the extensions 80, 82.

FIGS. 12A and 12C show that the distance between the inner faces of the sides 88, 90 of the lever 16 is greater than the distance between the outer faces of the latch head extensions 80, 82. FIG. 12C shows the H-shaped of the latch head 78.

FIG. 13 shows that the longer latch head extension 80 has a greater length than does the shorter latch head extension 82. FIG. 13 further shows that a distal oblique edge 260 of lever side 90 of the lever 16 is adjacent to and parallel with the oblique closed edges of channels 236, 238 of latch head extension 82 when the lever 16 is in the closed position.

FIG. 14A shows that the pivot pin 76 extends through the lever 16 and housing 12. FIG. 14B shows that a distal oblique edge 262 of lever side 88 of the lever 16 is adjacent to and parallel with the oblique closed edges of channels 232, 234 of latch head extension 80 when the lever 16 is in the closed position. FIG. 14C shows the distal face of base 92 that includes the upper, lower, and intermediate horizontal ribs projecting distally from base 92.
