Claim 7

a T-shaped tongue having a stem integrally connected at one end thereof to the second portion of said body so as to project away from said second portion along a direction substantially parallel to said major surfaces, the other end of said stem adjoining a crossbar disposed along a direction substantially orthogonal to said stem.

Claim 8

a T-shaped tongue having a stem integrally connected at one end thereof to the second portion of said body so as to project away from said second portion along a direction substantially parallel to said major surfaces, the other end of said stem adjoining a crossbar disposed along a direction substantially orthogonal to said stem.

Claim 9

A latch as defined in claim 1 wherein each of said other segments has a contact bar integrally connected thereto so as to orthogonally project therefrom.

Claim 10

A latch as defined in claim 2 wherein said body and said tongue have a substantailly flat shape, and wherein each contact bar has a cylindrical shape.

Claim 11

A latch as defined in claim 3 wherein the distance between each contact bar and the one segment of its supporting arm is substantially equal to the thickness of said structure.

Claim 12

A latch as defined in claim 3 wherein the distance between said crossbar and the second portion of said body is substantially equal to the thickness of said structure.

Claim 13

A latch as defined in claim 5 wherein the second portion of said body has substantially U-shaped cutouts therein adjacent said stem.

Claim 14

A latch as defined in claim 2 wherein said receiving means comprises a substantially U-shaped groove adapted to fit snugly over the edge of said printed circuit board.

Claim 15

A latch as defined in claim 2 wherein said latch comprises a single piece of injection-molded plastic.

Claim 16

A latch in cooperative locking combination with a structure for securing a printed circuit board adjacent thereto comprising: a body having two major opposing surfaces adjoining a first portion, a second portion opposite said first portion, and two additional portions of said body opposite each other between said first and second portions, each additional portion including an L-shaped arm having one segment integrally connected to the second portion of said body so as to project away from one major surface of said body, the other segment of each arm extending away from the first portion of said body along a direction substantially parallel to said one major surface and having a contact bar integrally connected thereto so as to orthogonally project therefrom, means disposed adjacent to the first portion of said body along the major surface opposite said one surface for receiving an edge of said printed circuit board, a T-shaped tongue having a stem integrally connected at one end thereof to the second portion of said body so as to project away from said second portion along a direction substantially parallel to said major surfaces, the other end of said stem adjoining a crossbar disposed along a direction substantialy orthogonal to said stem,

Claim 17

A latch in cooperative locking combination with a structure for securing a printed circuit board adjacent thereto comprising: a body having two major opposing surfaces adjoining a first portion, a second portion opposite said first portion, and two additional portions of said body opposite each other between said first and second portions, each additional portion including an L-shaped arm having one segment integrally connected to the second portion of said body so as to project away from one major surface of said body, the other segment of each arm extending away from the first portion of said body along a direction substantially parallel to said one major surface and having a contact bar integrally connected thereto so as to orthogonally project therefrom, means disposed adjacent to the first portion of said body along the major surface opposite said one surface for receiving an edge of said printed circuit board, a T-shaped tongue having a stem integrally connected at one end thereof to the second portion of said body so as to project away from said second portion along a direction substantially parallel to said major surfaces, the other end of said stem adjoining a crossbar disposed along a direction substantialy orthogonal to said stem,

Claim 18

said structure having a neck defined by two shoulders spaced apart to support said arms, respectively, at the vertex joining the two segments of each arm in an orientation whereat said one segment rests against one side of said structure, and each contact bar abuts against said neck adjacent the side of said structure opposite said one side, said tongue passing through an aperture disposed in said structure beneath said neck such that said crossbar contacts said opposite side, said aperture being shaped so as to allow said crossbar to pass therethrough before making contact with said opposite side.

Claim 19

said structure having a neck defined by two shoulders spaced apart to support said arms, respectively, at the vertex joining the two segments of each arm in an orientation whereat said one segment rests against one side of said structure, and each contact bar abuts against said neck adjacent the side of said structure opposite said one side, said tongue passing through an aperture disposed in said structure beneath said neck such that said crossbar contacts said opposite side, said aperture being shaped so as to allow said crossbar to pass therethrough before making contact with said opposite side.

Claim 20

A latch in combination with a structure as defined in claim 9 wherein said aperture is T-shaped and has a stem opening with one end thereof disposed adjacent said neck and another end opposite said one end disposed away from said neck and adjoined to a crossbar opening, the width of said stem opening being greater than the width of said stem but less than the length of said crossbar.

Claim 21

A latch in combination with a structure as defined in claim 10 wherein said body and said tongue have a substantially flat shape, and wherein each contact bar has a cylindrical shape.

Claim 22

A latch in combination with a structure as defined in claim 11 wherein the distance between each contact bar and the one segment of its supporting arm is substantialy equal to the thickness of said structure.

Claim 23

A latch in combination with a structure as defined in claim 11 wherein the distance between said crossbar and the second portion of said body is substantially equal to the thickness of said structure.

Claim 24

A latch in combination with a structure as defined in claim 13 wherein the bottom of said body has substantially U-shaped cutouts therein adjacent said stem.

Claim 25

A latch in combination with a structure as defined in claim 10 wherein said receiving means comprises a substantially U-shaped groove adapted to fit snugly over the edge of said printed circuit board.

Claim 26
