Abstract
Abstract This freight lashing apparatus comprises freight contact bail means responsive to freight movements in a forward and in both lateral directions. An unlocking means is responsive to freight movement in a reverse direction. The freight contact bail means and the unlocking means are both operatively connected to freight locking means to retract the freight locking means and the bail means below the loading floor so as not to interfere with the freight movement, especially in an aircraft.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
256 words
A freight lashing apparatus for securing freight to a loading floor, comprising a frame structure, a first tilting axis (2a) held in said frame structure, bell crank lever means tiltably supported on said first tilting axis and having normally vertically extending arm means and normally horizontally extending arm means, roll over bail means (2) held by said normally vertically extending arm means, said roll over bail means having two slanted contact surfaces extending normally toward said horizontally extending arm means, push rod means, bar means (3a) connecting said normally horizontally extending arm means of said bell crank lever means to one end of said push rod means (3), said conneting bar means having free ends, guide slots in said frame structure, each of said free ends of said connecting bar means (3a) riding in a respective one of said guide slots, a freight locking mechanism (4,6), a second tilting axis (6a) also held in said frame structure and tiltably supporting said freight locking mechanism, means journaling the other end of said push rod means (3) to said freight locking mechanism above said second tilting axis, and unlocking means (8) operatively connected to said locking means, said roll over bail means being responsive to a forward and lateral freight movement and said unlocking means (8) being responsive to a reverse freight movement, whereby said bell crank lever means with the roll over bail means and the locking mechanism are tiltable into a retracted, lowered position below said loading floor in response to freight movement in any direction.
Claim 2
Dependent Claim
256 words
A freight lashing apparatus for securing freight to a loading floor, comprising a frame structure, a first tilting axis (2a) held in said frame structure, bell crank lever means tiltably supported on said first tilting axis and having normally vertically extending arm means and normally horizontally extending arm means, roll over bail means (2) held by said normally vertically extending arm means, said roll over bail means having two slanted contact surfaces extending normally toward said horizontally extending arm means, push rod means, bar means (3a) connecting said normally horizontally extending arm means of said bell crank lever means to one end of said push rod means (3), said conneting bar means having free ends, guide slots in said frame structure, each of said free ends of said connecting bar means (3a) riding in a respective one of said guide slots, a freight locking mechanism (4,6), a second tilting axis (6a) also held in said frame structure and tiltably supporting said freight locking mechanism, means journaling the other end of said push rod means (3) to said freight locking mechanism above said second tilting axis, and unlocking means (8) operatively connected to said locking means, said roll over bail means being responsive to a forward and lateral freight movement and said unlocking means (8) being responsive to a reverse freight movement, whereby said bell crank lever means with the roll over bail means and the locking mechanism are tiltable into a retracted, lowered position below said loading floor in response to freight movement in any direction.
Claim 3
Dependent Claim
79 words
The apparatus according to claim 1, wherein said frame structure has a rear end adjacent to said first tilting axis and a front end substantially adjacent to said unlocking means, and wherein said slanted contact surfaces of said roll over bail means extend laterally outside said frame structure, said slanted contact surfaces further extending downwardly away from said rear end and thus toward said front end, whereby said slanted contact surfaces are located ahead of said first tilting axis.
Claim 4
Dependent Claim
40 words
The apparatus according to claim 1, wherein said freight locking mechanism comprises guide means (4) effective in a given direction and freight latch means (6) effective in a plane extending substantially at a right angle relative to said given direction.
Claim 5
Dependent Claim
49 words
The apparatus according to claim 1, wherein said frame structure has a rear end adjacent said first tilting axis and wherein said guide slots for said free ends of the connecting bar means (3a) have a shape substantially following a circle segment extending downwardly and toward said rear end.
Claim 6
Dependent Claim
90 words
The apparatus according to claim 1, wherein said unlocking means (8) comprise a freight contact bail responsive to a reverse freight movement, a shaft (8a) tiltably supported in said frame structure and supporting said freight contact bail, actuating means (9) connected at one end thereof to said freight contact bail, and ratchet lever means pivotally connecting the other end of said actuating means (9) to said connecting bar means (3a), whereby the ratchet lever means (10, 10d) move downwardly said connecting bar means (3a) and thus out of dead center.
Claim 7
Dependent Claim
87 words
The apparatus according to claim 5, wherein said actuating means of said unlocking means comprise spring compensating means including piston cylinder means and a piston rod (9a, 9c) and a compression spring on said piston rod, said ratchet lever means (10) comprising cooperating lever arms (10c, 10d) and a cam surface (10b) arranged for entraining one of said cooperating lever arms in response to a forward tilTing of the other of said cooperating lever arms whereby said connecting bar means (3a) are moved out of dead center.
Claim 8
Dependent Claim
92 words
The apparatus according to claim 1, wherein said freight locking mechanism comprises guide means (4) effective in a given direction, and latch means (6) effective in a plane extending substantially at a right angle relative to said given direction, said guide means (4) effective in a given direction comprising locking pawl means (5) journaled to said guide means and including side pieces (5c) and a cross piece (5b) interconnecting said side pieces, said locking pawl means being arranged for effectively locking said freight latch means (6) in its operative, freight latching position.
Claim 9
Dependent Claim
60 words
The apparatus according to claim 1, wherein said freight locking mechanism comprises latch means (6) effective in a given plane, said apparatus further comprising a foot pedal arranged outside said frame structure, and lever means connecting said foot pedal to said latch means for locking said latch means in a freight latching position by an operation of said foot pedal.
Claim 10
Dependent Claim
81 words
The apparatus according to claim 1, further comprising a contact safety device (11) including a bracket (1i) secured to said frame structure for supporting said contact safety device (11) which comprises a pin (11a) movable back and forth and arranged normally for cooperating engagment with said unlocking means, said safety device further comprising cam lever means (11b, 11e) pivoted to said pin for withdrawing said pin from engagement with said unlocking means in response to tiltng of said cam lever means.
Claim 11
Dependent Claim
48 words
The apparatus according to claim 1, further comprising torsion spring return means (12) arranged on said first tilting axis (2a), said torsion spring return means being biased against said roll over bail means (2) for returning said roll over bail means and thus also said freight locking mechanism.
Claim 12
Dependent Claim
39 words
The apparatus according to claim 1, wherein said freight locking mechanism comprises latch means (6) effective in a given plane, vertical axes means secured to said latch means, and roller means (4a) rotatably supported on said vertical axes means.
