## Abstract

A pivotal gate latch (1), including housing (2), in which a pivotal sleeve (8) and gate post embracing plates (9 and 10) are disposed for pivotal movement. A latching flange (11) is arranged within the housing that engages with an upper disposed detent or shoulder (21) formed in the pivotal sleeve, to secure the gate frame (P) in place and sustain it in a locked condition. Vertical displacement of the latching flange, either manually or through remote cables, permits horizontal pivoting the latch plates in either direction, after which time, if the gate is biased by associated springs or cables, the gate may be self-centering, and locked automatically by the return of the latching flange to the rest position within the shoulder.

## Claims

### Claim 1

A pivotal gate latch for use with a pivoting gate and fixed gate post, comprising:
a housing including upper and lower vertically aligned brackets, said housing adapted for attachment to said fixed gate post;
a pivotal latch member secured to said housing by said upper and lower brackets, said pivoting latch member adapted for retaining said pivoting gate;
a locking member seated within said upper bracket, coaxial with said pivoting latch member, said locking member extending above said upper bracket and below said lower bracket and having first and second positions, said locking member preventing pivotal movement of said pivoting latch member in said first position, and permitting unrestrained pivotal movement of said pivoting latch member in said second position;
said pivoting latch member comprising a cylindrical sleeve, said sleeve having upper and lower faces, and an outer cylindrical surface, said sleeve of sufficient length to seat within said upper and lower vertically aligned brackets;
a first latch plate secured on a peripheral edge of said outer cylindrical surface;
a second latch plate secured on the peripheral edge of said outer cylindrical surface apart from, and horizontally aligned with, said first latch plate;
said first and second latch plates divergently aligned to retain said pivoting gate when said latch member is in said first position, said latch plate extending laterally and exteriorly between said upper and lower brackets;
said cylindrical sleeve further includes a shoulder formed in said upper face, said shoulder adapted to receive said locking member in said first position;
a locking flange of sufficient width to prevent rotation of said locking member within said upper bracket;
a bar having upper and lower ends, the upper end of said bar secured to a peripheral edge of said locking flange, and said bar of sufficient length to extend above said lower bracket;
an actuating member secured to the upper end of said bar, said actuating member extending above said upper bracket;
said locking member further includes a tubular sleeve secured around said bar below said locking flange, said tubular sleeve having an outer diameter smaller than an inner diameter of said cylindrical sleeve, such that said tubular sleeve seats coaxially within said cylindrical sleeve;
said locking flange being configured to seat within said shoulder in said first position and secure said cylindrical sleeve against pivotal movement;
said locking flange being configured to abut said upper face of said cylindrical sleeve in said second position, and disposing said cylindrical sleeve unrestrained against pivotal rotation;
said first position of said locking member is a rest position, and said second position of said locking member is an upward vertically displaced position;
said pivotal gate latch further including a closure plate, said closure plate secured to the upper face of said upper bracket, said closure plate providing closure for the upper edge of said upper bracket, said closure plate including an axial opening therein through which said locking means passes, and said locking means constrained against rotational movement by said closure plate.

### Claim 2 (depends on 1)

The pivotal gate latch of claim 1 said wherein actuating member comprises a ring.

### Claim 3 (depends on 1)

The pivotal gate latch of claim 1 wherein said pivotaing latch member is capable of rotational movement through an arc greater than 90.degree..

### Claim 4 (depends on 1)

The pivoting gate latch of claim 1 wherein said pivoting latch member is configured to retain said pivoting gate perpendicular to said housing when said locking member is in said first position.

### Claim 5 (depends on 1)

The pivoting gate latch of claim 1 wherein said bar further includes an aperture adjacent said lower end, said aperture configured to receive a locking pin and prevent vertical displacement of said locking member.

### Claim 6 (depends on 1)

The pivotal gate latch of claim 1 and wherein said locking flange is fixed extending downwardly at an acute angle with said bar.
