Abstract
Abstract Support means for containers adapted for location transfer and selected detached surface placement, wherein adjustable length of legs provide for surface support in an extended condition, and when in a retracted condition being substantially housed within the confines of the containers to facilitate their transfer, with appropriate lock means for the different leg conditions, and container and leg construction providing strength, ease of operation and protective confinement of the legs within the horizontal periphery of the container.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
Support means for containers comprising: A. a plurality of vertically disposed, axially extensible support legs attached to said containers; B. said legs being vertically axially movable from a retracted storage position to an extended container support position; C. means mounting said legs for horizontal movement in horizontally retracted and extended position; D. vertically disposed pockets within the body of said container, said legs in retracted position confined within said pockets; E. latching means to secure the said legs in a vertically retracted position; F. said legs including inner and outer leg portions telescopic with respect to one another, one said portion being attached to said means mounting said legs for horizontal movement; G. means carried by said legs including movable lock pins for interengaging and locking the inner and outer leg portions, and means operatively associated with said lock pins and the container body for movement of said lock pins into interengaging lock position when said horizontal movement means are horizontally extended, and to disengage said lock pins from said legs upon retraction of said horizontal movement means, said legs being axially vertically extended prior to horizontal movement.
Claim 2
Dependent Claim
188 words
Support means for containers comprising: A. a plurality of vertically disposed, axially extensible support legs attached to said containers; B. said legs being vertically axially movable from a retracted storage position to an extended container support position; C. means mounting said legs for horizontal movement in horizontally retracted and extended position; D. vertically disposed pockets within the body of said container, said legs in retracted position confined within said pockets; E. latching means to secure the said legs in a vertically retracted position; F. said legs including inner and outer leg portions telescopic with respect to one another, one said portion being attached to said means mounting said legs for horizontal movement; G. means carried by said legs including movable lock pins for interengaging and locking the inner and outer leg portions, and means operatively associated with said lock pins and the container body for movement of said lock pins into interengaging lock position when said horizontal movement means are horizontally extended, and to disengage said lock pins from said legs upon retraction of said horizontal movement means, said legs being axially vertically extended prior to horizontal movement.
Claim 3
Dependent Claim
72 words
Apparatus as claimed in claim 1, a lock housing within the upper end of the inner leg portion, blocks mounting said lock pins, horizontally supported in said housing and being slidable toward and away from one another, said outer and inner leg portions having side openings therethrough, said lock pins being extendible between and into mating side openings upon vertical extension of said leg portions to lock the same in extended position.
Claim 4
Dependent Claim
67 words
Apparatus as claimed in claim 2, a cam-shaped leg lock lever rotatably mounted on said lock housing, said lever, said housing, and said blocks having mating openings therein, pins extending in said openings interengaging said lever and said blocks and adapted upon rotation of said lever to slide said blocks in said housing for extension or retraction of said lock pins into and out of locking positions.
Claim 5
Dependent Claim
51 words
Apparatus as claimed in claim 3, including a lever operating block attached to said container body within said vertical pocket, and position for engagement by said leg lock lever upon horizontal movement of said legs from retracted to extended position to rotate said lever to extend said pins into locking position.
Claim 6
Dependent Claim
49 words
Apparatus as claimed in claim 4, a portion of said cam-shaped lever being engageable with an inner wall of said pocket upon movement of said leg horizontally into said pocket to rotate said lever for retraction of said lock pins to permit vertical telescopic retraction of said leg portions.
Claim 7
Dependent Claim
53 words
Apparatus as claimed in claim 5 and including a surface-engaging foot on the lower end of said inner leg portion adapted for surface contact and support of said leg, and latch means on said container selectively contactible with said foot, with said leg in vertically retracted position, for vertical securement of said leg.
Claim 8
Dependent Claim
40 words
Apparatus as claimed in claim 8, said openings in said lever and said block housing being elongated and angularly arranged with respect to one another to permit relative sliding movement of said pins therein upon rotation of said lock lever.
