Abstract
Abstract A safety rail for vehicle doorways mounted on the inside of the living unit and consisting of an elongated member mounted on the doorway frame for pivotal movement from a position spanning the doorway opening to a position clearing the opening. A member connected to the inside of the frame releasably holds the rail across the opening and another member connected to the other side of the doorway opening holds the rail clear of the opening. The rail may be designed to carry a catch for engagement with a lock mechanism mounted on the door which is operated by a key from the inside of the vehicle and engages a latch catch mounted on the door. The rail may also be designed to carry a latch which is manually operated from the inside of the vehicle and engages a latch catch mounted on the door.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
209 words
A safety rail for a vehicle living unit having a door frame with first and second sides and a door hingedly mounted for pivotal movement outwardly comprising: a. an elongated safety rail adapted for two way pivotal mounting on one side of the door frame on the inside of the living unit and having a first position spanning the door opening at about waist level and a second position clearing the door opening; b. quick release means adapted for connection to said door frame for releasably holding said safety rail in said first generally horizontal position, having a pin preventing rotation in a plane parallel to the door frame and having a member preventing movement of said safety rail in a direction perpendicular to said door; c. means adapted for connection to said door frame for releasably holding said safety rail in said second generally vertical position; and d. pivot means adapted for mounting on said first side of said door frame for pivotally holding said safety rail having a member permitting movement of said rail in a plane parallel to said frame through an arc of at least 90* and another member further permitting limited pivotal movement of said rail generally perpendicular to the plane of said frame.
Claim 2
Dependent Claim
209 words
A safety rail for a vehicle living unit having a door frame with first and second sides and a door hingedly mounted for pivotal movement outwardly comprising: a. an elongated safety rail adapted for two way pivotal mounting on one side of the door frame on the inside of the living unit and having a first position spanning the door opening at about waist level and a second position clearing the door opening; b. quick release means adapted for connection to said door frame for releasably holding said safety rail in said first generally horizontal position, having a pin preventing rotation in a plane parallel to the door frame and having a member preventing movement of said safety rail in a direction perpendicular to said door; c. means adapted for connection to said door frame for releasably holding said safety rail in said second generally vertical position; and d. pivot means adapted for mounting on said first side of said door frame for pivotally holding said safety rail having a member permitting movement of said rail in a plane parallel to said frame through an arc of at least 90* and another member further permitting limited pivotal movement of said rail generally perpendicular to the plane of said frame.
Claim 3
Dependent Claim
39 words
A safety rail as described in claim 1 comprising: a. a locking mechanism adapted for mounting on the outside face of said door; and b. a catch mounted on said safety rail for locking engagement with said lock mechanism.
Claim 4
Dependent Claim
63 words
A safety rail as described in claim 1 comprising: a. a manually engageable latch mounted on said safety rail and having a manually engageable latch handle on the inside face of said safety rail adpated for locking said door from the inside of said living unit; and b. a latch catch adapted for mounting on said door for releasable engagement with said latch.
Claim 5
Dependent Claim
101 words
A safety rail as described in claim 2 comprising: a. said quick release means for holding said safety rail in said first position including a pin and a guide member for positively guiding said rail onto said pin at substantially the same arcuate position when said safety rail approaches said first position from said second position on a path at right angles to the plane of said door frame; and b. said pivot means including a joint permitting limited pivotal movement of said safety rail at right angles to said door frame permitting mating of said rail with said guide member.
Claim 6
Dependent Claim
112 words
A safety rail as described in claim 4 comprising: a. a manually engageable latch mounted on said safety rail and having a manually engageable latch handle on the inside face of said safety rail adapted for locking said door from the inside of said living unit; b. a latch catch mounted on said door for releasable engagement with said latch; c. said safety rail including a pair Of vertically spaced members and a pair of cross braces connecting said spaced members; and d. said lock catch and said manually engageable latch are mounted on one of said cross braces and said pivot means is mounted on the other of said cross braces.
