Modular wall phone latching mechanism

Claim 2

A latch mechanism of a wall telephone instrument for affixing said wall telephone instrument to a wall telephone mounting plate, wherein said wall plate has at least one headed stud extending from the face thereof with said stud spaced from a mounting aperture bearing a modular jack and in which said instrument has an opening in its base for receiving said stud and has a plug member adapted to mate with the jack, said latch mechanism comprising a flat spring member having a head section adapted to engage the head of said stud in a latch position affixing the instrument to said plate, said spring member including a body extending from said head section toward an exposed edge of said instrument with said spring body normally biased toward the headed stud, and a holding member for holding said spring member in engagement with the head of said stud, said holding member accessible from the exposed edge of the instrument to release the engagement of the head section of the spring member with said headed stud to allow removal of the instrument from the mounting plate.

Claim 3

A latch mechanism as claimed in claim 1, wherein said spring body is mounted in said instrument base and said body has a mounting tail securing said spring body to said instrument enabling normal flexing movement of said spring member away from the mounting plate.

Claim 4

In combination, a base plate of a telephone set for mating with the front face of a wall receptacle and a device for mounting on said base plate to latch the base plate and telephone set carried thereon to said wall receptacle, in which the front face of said receptacle has a jack aperture therein and at least one headed rivet spaced from said aperture, said base plate including a line cord terminating in a modular plug for mating with a jack within the aperture and a keyhole opening for receiving said headed rivet, said latching device including a leaf spring member having a head section adapted to engage the headed rivet in a condition latching the telephone set to the wall receptacle, said leaf spring mounted in said base plate through a mounting opening therein, the head section of said leaf spring normally biased to extend through an opening in said base plate toward the front face of the receptacle, and in which there is means accessible from externally of the base plate and telephone set for releasing said mating on manual actuation of said release means.

Claim 5

In combination, a base plate of a telephone set for mating with the front face of a wall receptacle and a device for mounting on said base plate to latch the base plate and telephone set carried thereon to said wall receptacle, in which the front face of said receptacle has a jack aperture therein and at least one headed rivet spaced from said aperture, said base plate including a line cord terminating in a modular plug for mating with a jack within the aperture and a keyhole opening for receiving said headed rivet, said latching device including a leaf spring member having a head section adapted to engage the headed rivet in a condition latching the telephone set to the wall receptacle, said leaf spring mounted in said base plate through a mounting opening therein, the head section of said leaf spring normally biased to extend through an opening in said base plate toward the front face of the receptacle, and in which there is means accessible from externally of the base plate and telephone set for releasing said mating on manual actuation of said release means.

Claim 6

The combination of claim 3, in which said leaf spring has a stepped tail end for mating with a pin in said base for preventing sliding movement of the body of said leaf spring, and in which the release means comprises a shaped wire spring engaging said leaf spring at said head section and said wire spring has a free end extending out of said base.

Claim 7

The combination of claim 4, in which said wire spring is shaped to be readily detachable from said leaf spring to enable slide release of the leaf spring from said base.

Claim 8

A latch mechanism adapted to mount in a modular wall telephone instrument including a base for automatic latching action cooperative with a headed stud on a wall receptacle plate for receiving said instrument, in which there is a keyhole opening in said instrument for receiving said headed stud, said latch mechanism including a latch spring intruding into said keyhole opening and a mounting in said instrument for said latch spring to enable said spring to be depressed into said instrument by the impingement thereon of the headed stud, wherein said latch spring is biased so as to automatically position itself in latching engagement with said stud when said stud is moved to the remote end of the keyhole opening, in which said latch spring comprises a formed flat spring with a transverse groove at the end thereof which intrudes into said keyhole opening, and in which said latch spring is assembled into said base within a slot in said base, further comprising a formed wire spring for engaging said flat spring at the intruding end thereof, and said wire spring extends through an opening in the wall of said base to render the mechanism accessible from externally of the base.

Claim 9

A latch mechanism adapted to mount in a modular wall telephone instrument including a base for automatic latching action cooperative with a headed stud on a wall receptacle plate for receiving said instrument, in which there is a keyhole opening in said instrument for receiving said headed stud, said latch mechanism including a latch spring intruding into said keyhole opening and a mounting in said instrument for said latch spring to enable said spring to be depressed into said instrument by the impingement thereon of the headed stud, wherein said latch spring is biased so as to automatically position itself in latching engagement with said stud when said stud is moved to the remote end of the keyhole opening, in which said latch spring comprises a formed flat spring with a transverse groove at the end thereof which intrudes into said keyhole opening, and in which said latch spring is assembled into said base within a slot in said base, further comprising a formed wire spring for engaging said flat spring at the intruding end thereof, and said wire spring extends through an opening in the wall of said base to render the mechanism accessible from externally of the base.
