Abstract

A new latch mechanism for a vehicle glove box doors, or other locking requirements, wherein the door is to be held in flush position relative to an adjoining panel surface, said latch mechanism comprising, an injection molded plastic body, an injection molded plastic handle, an injection molded lock member or actuator member, with the previous parts being spring biased into their appropriate positions during operation of the latch mechanism, and with the actuator member being of sufficient width to provide a strong retaining force for the latch mechanism upon the event of a vehicle crash impact and also acting to provide a wide contact locking surface to thereby assist in preventing flex distortions between said door and panel surface.

Claims

1. A latch mechanism for securing a door in flush position relative to an adjoining panel surface, said latch mechanism comprising,

(i) first means to provide a housing for the mechanism,

(ii) a second means which operates as a handle, said handle integral with and pivotable on an axle member, for unlocking the latch mechanism, with the second means being spring biased to a generally flush position relative to the door and panel surface,

(iii) a third actuator means centrally located with respect to said handle, which is movable between at least first and second positions to lock and unlock the latch mechanism, and said actuator means including a spring member which biases the actuator means into a locked position,

said actuator means being of sufficient width to provide a strong retaining force for the latch mechanism upon the event of a vehicle crash impact and also to provide a wide contact locking surface to thereby assist in preventing flex distortions between said door and panel surface.

2. The invention of claim 1 wherein,

said mechanism consists of no more than three plastic parts, and helically formed spring member to bias the latch mechanism into its locking position.

3. The invention of claim 1 wherein,

said actuator means has a sloped surface on one side thereof which acts to cam the actuator means to a depressed position upon closing of the door,

and said actuator means is generally centrally located relative to the width of the housing.

4. The invention of claim 3 wherein,

said first and second means are made of a glass filled plastic, and the actuator means is made of a strong smooth low friction plastic, to thereby provide a latch mechanism which is very light weight, stable, and safe under crash conditions.

5. The invention of claim 1 wherein,

said mechanism consists of no more than three plastic parts, and helically formed spring member to bias the latch mechanism into its locking position,

said actuator means has a sloped surface on one side thereof which acts to cam the actuator means to a depressed position upon closing of the door,

and said actuator means is generally centrally located relative to the width of the housing.

6. The invention of claim 5 wherein,

said first and second means are made of a glass filled plastic, and the actuator means is made of a strong smooth low friction plastic, to thereby provide a latch mechanism which is very light weight, stable, and safe under crash conditions.

7. The invention of claim 1 wherein,

said second means has a traverse axle member with opposite ends thereof mounted in receptive apertures of the housing, said actuator means being generally centrally located relative to said transverse axle member.

8. The invention of claim 7 wherein,

said mechanism consists of no more than three plastic parts, and helically formed spring member to bias the latch mechanism into its locking position.

9. The invention of claim 8 wherein,

said first and second means are made of a glass filled plastic, and the actuator means is made of a strong smooth low friction plastic, to thereby provide a latch mechanism which is very light weight, stable, and safe under crash conditions.

10. The invention of claim 9 wherein,

said housing has flange members at each end thereof, with at least two apertures in each flange to thereby facilitate mounting of the latch mechanism.

11. A latch mechanism for securing a vehicle glove box door in a flush position relative to an adjoining panel surface, said latch mechanism comprising:

a box-like housing have a plurality of mounting flanges attached thereto, said mounting flanges positioned such that they may be placed adjacent said door for use in securing said box-like housing to said door, said housing further including a channel disposed therein;

a latch slidably disposed within said housing, said latch including a transversely extending rail member which is slidably disposed in said channel, said latch member further including an outwardly extending shoulder portion;

a handle pivotally mounted on said housing, said handle including an axle member integral with said handle and further including a lever arm extending radially outward from said axle member;

a spring disposed about said axle member and acting to rotate said axle member such that said handle is urged inward towards said door surface; and

a spring member disposed between said housing and said latch member operative to urge said latch member outward into a latch position.

12. A latch mechanism for securing a vehicle glove box door in a flush position relative to an adjoining panel surface, said latch mechanism comprising:

a box-like housing have a plurality of mounting flanges attached thereto, said mounting flanges positioned such that they may be placed adjacent said door for use in securing said box-like housing to said door, said housing further including a channel disposed therein and a slot in a sidewall of said housing;

a latch slidably disposed within said housing, said latch including a transversely extending rail member which is slidably disposed in said channel, said latch member further including an outwardly extending shoulder portion said shoulder portion extending outward through said slot;

a handle pivotally mounted on said housing, said handle including an axle member integral with said handle and further including a lever arm extending radially outward from said axle member wherein said lever arm engages said shoulder;

a spring disposed about said axle member and acting to rotate said axle member such that said handle is urged inward towards said door surface; and

a spring member disposed between said housing and said latch member operative to urge said latch member outward into a latch position.

13. A latch mechanism as set forth in claim 12 wherein said axle member includes opposite ends adapted to fit into apertures on said flange portions, each of said apertures including an upwardly sloped surface molded into the flange portions and the ends of the axial portion including a sloped surface thereon whereby the complementary sloped surfaces facilitate the assembly of the axle member to the housing to form a firm tight fitting engagement.

14. A latch mechanism as set forth in claim 13 wherein said latch mechanism consists of no more than three parts and a helical spring for biasing the latch into a locking position.

15. A latch mechanism as set forth in claim 14 wherein said housing and said handle are made of a glass filled plastic and said latch is made of a strong smooth low friction plastic.
