Furthermore, particular features of one embodiment can replace corresponding features in another embodiment or can supplement other embodiments unless otherwise indicated by the drawings or this specification.
100151 A trailer 10 can include an open bed 12, a frame 14, an actuator 16, and a pin 18. The open bed 12 can extend a width (referenced at 20) and a length (referenced at 22). Thc frame 14 can support the open bed 12. Wheels, such as wheels 24 and 26, can be mounted to the frame 14 to allow the trailer 10 to be moved. The trailer 10 can be utilized as an oilfield float trailer.
[0016] The actuator 16 can be mounted on the frame 14. The pin 18 can be mounted on the frame 14 along a periphery 28 of the open bed 12. The trailer 10 can include a plurality of pins, including pin 18 as well as pins 118, 218, 318 and 418. Each of the pins 18 ¨ 418 can be drivable by the actuator 16 in reciprocating movement transverse to the length 22 between a first pin end limit of travel defining a retracted position and a second pin end limit of travel defining an extended position.
Each of the pins 18 ¨ 418 can be recessed from the open bed 12 when in the retracted position and extend above the open bed 12 when in the extended position.
[0017] A rod 30 can be operably disposed between the actuator 16 and the pins 18 ¨ 418. The rod 30 can be drivable in reciprocating rectilinear movement along at least a portion of the length 22 by the actuator 16 between a first rod end limit of travel and a second rod end limit of travel. The rod 30 can be guided and supported in motion by one or more sleeves, such as sleeves 32 and 132, disposed along the length 22.
[0018] A cam, such as cam 34, can be mounted on the rod 30 and can be disposed in slidable engagement with the pin 18 to move the pin 18 between the first and second pin end limits of travel. The exemplary embodiment of the present disclosure can include a plurality of cams mounted on the rod 30. Each cam can be disposed in slidable engagement with one of the plurality of pins 18 ¨418 to concurrently move each the plurality of pins 18 ¨ 418 between respective the first and second pin end limits of travel. The rod 30 can thus extend greater than half of the length 22 to engage all of the pins 18 ¨418.
[0019] Referring now to Figures 4 and 5, the exemplary cam 34 can be a generally triangular plate extending away from the rod 30 in a direction transverse to the length 22. The cam 34 can define a sliding surface 36 engaging the pin 18. The sliding surface 36 can be defined by a closed slot 38. The exemplary sliding surface 36 engaging the pin 18 can be straight. The rate of movement transfer between the cam 34 and the pin 18 can therefore be linear.
[0020] The exemplary pin 18 can be guided and supported in movement by a sleeve 62 mounted to the frame 14. The exemplary pin 18 can include a first shaft portion 40 extending vertically between a base end 42 and a distal end 44. The distal end 44 can be recessed from or flush with the open bed 12 when the pin 18 is in the retracted position. The distal end 44 can be positioned above the open bed 12 when the pin 18 is in the extended position, as shown in Figure 4.
10021] The exemplary pin 18 can also include a second shaft portion 46 extending transverse to the first shaft portion 40. The exemplary second shaft portion 46 can be a cross-pin passing through a yoke defined by the base end 42, as best shown in Figure 2.
The second shaft portion 46 can be rotatable relative to the first shaft portion 40 and ride along the sliding surface 36.
[0022] Figure 3 is a partial side view of an exemplary embodiment of the present disclosure wherein the pin 18 is shown in the retracted position and Figure 4 is a partial side view of an exemplary embodiment of the present disclosure wherein the pin 18 is shown in the extended position. A reference point 48 has been illustrated in Figures 3 and 4. The reference point 48 is a fixed point on the rod 30. When the pin 18 is the retracted position, as shown in Figure 3, the rod 30 can be moved in the direction referenced at 50, along the length 22. As the rod 30 is moved in the direction 50, the second shaft portion 46 can ride up the sliding surface 36. Further, the second shaft portion 46 can urge the first shaft portion 40 upwardly. When the rod 30 has moved a predetermined amount (as illustrated by the relative positions of the reference point 48 in Figures 3 and 4), the pin 18 will have moved from the retracted position to the extended position. When the rod 30 has moved the predetermined amount in a direction opposite to direction 50 (as illustrated by the relative positions of the reference point 48 in Figures 4 and 3), the pin 18 will have moved from the extended position to the retracted position.
[0023] Figure 5 illustrates another exemplary embodiment of the present disclosure. A rod 30a can drive a cam 34a to drive a pin 18a between a retracted position (illustrated) and an extended position in which the pin 18a extends above an open bed 12a. The rod 30a can move along a length 22a of the open bed 18a. The cam 34a can define a sliding surface 36a. The cam 34a can be an arcuate plate. The sliding surface 36a can be arcuate. The rate of movement transfer between the cam 34a and the pin 18a can therefore be variable.
[0024] In Figures 1 and 2, the exemplary actuator 16 can include an electronic motor with appropriate gearing to convert rotation to rectilinear movement.
Alternatively, the actuator 16 can be a cylinder, such as hydraulic cylinders or pneumatic cylinders. Figure 6 illustrates another exemplary embodiment of the present disclosure.
The actuator 16b can be a purely mechanical arrangement. The actuator 16b can include a lever 52b. The lever 52b can be engageable with gears of the actuator 16b.
Cranking of the lever 16b by a user can result in rectilinear movement of a rod 30b to move a cam 34b, to drive a pin 18b between an extended position and a retracted position relative to an open bed 12b.
100251 It is noted that the actuator 16, rod 30, sleeves 32, 132, and cam 34 are shown exposed in Figures 1 and 2, but can be enclosed within the frame 12 in one or more embodiments of the present disclosure. The actuator 16, rod 30, sleeves 32, 132, and cam 34 are shown disposed in a pocket 54 defined by the frame 14 in Figures 1 and 2. One or more panels can be releasibly engaged with the frame 14 to shield the actuator 16, rod 30, sleeves 32, 132, and cam 34.
[0026] Figure 7 schematically illustrates another exemplary embodiment of the present disclosure. A trailer 10a can include an open bed 12 supported by a frame (not visible). A first actuator 16c can be mounted on a first side of the frame. A
second actuator 116c can be mounted on a second side of the frame. A first plurality of pins such as pin 18c can each be mounted on the first side of the frame along a periphery 28a of the open bed 12a and be drivable by the first actuator 16c in reciprocating movement transverse to a length 22c between a first end limit of travel defining a retracted position and a second end limit of travel defining an extended position. A second plurality of pins such as pin 118c can each be mounted on the second side of the frame along the periphery 28a of the open bed 12a and be drivable by the second actuator 116c in reciprocating movement transverse to the length 22c between a first pin end limit of travel defining a retracted position and a second pin end limit of travel defining an extended position.
[0027] The exemplary actuators 16c, 116c can be electronically-controlled valves and be connected to a source of pressurized fluid 56c. The source of pressurized fluid 56c can be associated with a tractor/truck 58c operable to pull the trailer 10c. A
controller 60c can be operable to control both of the first and second actuators 16c, 116c.
The controller 60c can be positioned in the tractor 58c to be operated by a driver of the tractor 58c. The driver can operate the controller 60c through a button, a switch, a knob, through voice commands, or some other modality. The controller 60c can control one or both of the valve-actuators 16c, 116c to open and thereby direct fluid to the pins 18c, 118c and the other pins. Lines 64c, 164c, and 68 represent fluid lines. Lines 66, 166c, represent lines of electrical communication. Each pin can be disposed in a sleeve defining a fluidly sealed chamber. Each pin can thus define a fluid cylinder.
The driver can thus control the pins to move to the extended position through the controller 60c.
100281 Figure 8 illustrates another exemplary embodiment of the present disclosure. A rod 30d can drive a cam 34d to drive a pin 18d between a retracted position and an extended position. The pin 18d is guided in motion by a sleeve 62d. The cam 34d can define a sliding surface 36d. The cam 34d can be selectively engaged, disengaged and re-engaged with the rod 30d. The cam 34d can be received in a slot in the rod 30d.
the slot can define a bottom to prevent the cam 34d from sliding completely through the rod 30d. Apertures can extend through the rod 30d to the bottom of the slot.
Additional apertures can be defined in the bottom of the cam 34d. The apertures in the cam 34d can be threaded. The apertures in the cam 34d can be aligned with the apertures in the rod 30d. Threaded fasteners, such as fastener 70d, can be received in the apertures in the rod 30d and threadingly engaged the apertures in the cam 34d to selectively engage the rod 30d and the cam 34d together. This allows the cam 34d to be replaced with another cam if another pattern of movement of the pin 18d is desired.
100291 While the present disclosure has been described with reference to an exemplary embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the present disclosure without departing from the essential scope thereof. Therefore, it is intended that the present disclosure not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this present disclosure, but that the present disclosure will include all embodiments falling within the scope of the appended claims.
Further, the "present disclosure" as that term is used in this document is what is claimed in the claims of this document. The right to claim elements and/or sub-combinations that are disclosed herein as other present disclosures in other patent documents is hereby unconditionally reserved.

100151 A trailer 10 can include an open bed 12, a frame 14, an actuator 16, and a pin 18. The open bed 12 can extend a width (referenced at 20) and a length (referenced at 22). Thc frame 14 can support the open bed 12. Wheels, such as wheels 24 and 26, can be mounted to the frame 14 to allow the trailer 10 to be moved. The trailer 10 can be utilized as an oilfield float trailer.
[0016] The actuator 16 can be mounted on the frame 14. The pin 18 can be mounted on the frame 14 along a periphery 28 of the open bed 12. The trailer 10 can include a plurality of pins, including pin 18 as well as pins 118, 218, 318 and 418. Each of the pins 18 ¨ 418 can be drivable by the actuator 16 in reciprocating movement transverse to the length 22 between a first pin end limit of travel defining a retracted position and a second pin end limit of travel defining an extended position.
Each of the pins 18 ¨ 418 can be recessed from the open bed 12 when in the retracted position and extend above the open bed 12 when in the extended position.
[0017] A rod 30 can be operably disposed between the actuator 16 and the pins 18 ¨ 418. The rod 30 can be drivable in reciprocating rectilinear movement along at least a portion of the length 22 by the actuator 16 between a first rod end limit of travel and a second rod end limit of travel. The rod 30 can be guided and supported in motion by one or more sleeves, such as sleeves 32 and 132, disposed along the length 22.
[0018] A cam, such as cam 34, can be mounted on the rod 30 and can be disposed in slidable engagement with the pin 18 to move the pin 18 between the first and second pin end limits of travel. The exemplary embodiment of the present disclosure can include a plurality of cams mounted on the rod 30. Each cam can be disposed in slidable engagement with one of the plurality of pins 18 ¨418 to concurrently move each the plurality of pins 18 ¨ 418 between respective the first and second pin end limits of travel. The rod 30 can thus extend greater than half of the length 22 to engage all of the pins 18 ¨418.
[0019] Referring now to Figures 4 and 5, the exemplary cam 34 can be a generally triangular plate extending away from the rod 30 in a direction transverse to the length 22. The cam 34 can define a sliding surface 36 engaging the pin 18. The sliding surface 36 can be defined by a closed slot 38. The exemplary sliding surface 36 engaging the pin 18 can be straight. The rate of movement transfer between the cam 34 and the pin 18 can therefore be linear.
[0020] The exemplary pin 18 can be guided and supported in movement by a sleeve 62 mounted to the frame 14. The exemplary pin 18 can include a first shaft portion 40 extending vertically between a base end 42 and a distal end 44. The distal end 44 can be recessed from or flush with the open bed 12 when the pin 18 is in the retracted position. The distal end 44 can be positioned above the open bed 12 when the pin 18 is in the extended position, as shown in Figure 4.
10021] The exemplary pin 18 can also include a second shaft portion 46 extending transverse to the first shaft portion 40. The exemplary second shaft portion 46 can be a cross-pin passing through a yoke defined by the base end 42, as best shown in Figure 2.
The second shaft portion 46 can be rotatable relative to the first shaft portion 40 and ride along the sliding surface 36.
[0022] Figure 3 is a partial side view of an exemplary embodiment of the present disclosure wherein the pin 18 is shown in the retracted position and Figure 4 is a partial side view of an exemplary embodiment of the present disclosure wherein the pin 18 is shown in the extended position. A reference point 48 has been illustrated in Figures 3 and 4. The reference point 48 is a fixed point on the rod 30. When the pin 18 is the retracted position, as shown in Figure 3, the rod 30 can be moved in the direction referenced at 50, along the length 22. As the rod 30 is moved in the direction 50, the second shaft portion 46 can ride up the sliding surface 36. Further, the second shaft portion 46 can urge the first shaft portion 40 upwardly. When the rod 30 has moved a predetermined amount (as illustrated by the relative positions of the reference point 48 in Figures 3 and 4), the pin 18 will have moved from the retracted position to the extended position. When the rod 30 has moved the predetermined amount in a direction opposite to direction 50 (as illustrated by the relative positions of the reference point 48 in Figures 4 and 3), the pin 18 will have moved from the extended position to the retracted position.
[0023] Figure 5 illustrates another exemplary embodiment of the present disclosure. A rod 30a can drive a cam 34a to drive a pin 18a between a retracted position (illustrated) and an extended position in which the pin 18a extends above an open bed 12a. The rod 30a can move along a length 22a of the open bed 18a. The cam 34a can define a sliding surface 36a. The cam 34a can be an arcuate plate. The sliding surface 36a can be arcuate. The rate of movement transfer between the cam 34a and the pin 18a can therefore be variable.
[0024] In Figures 1 and 2, the exemplary actuator 16 can include an electronic motor with appropriate gearing to convert rotation to rectilinear movement.
Alternatively, the actuator 16 can be a cylinder, such as hydraulic cylinders or pneumatic cylinders. Figure 6 illustrates another exemplary embodiment of the present disclosure.
The actuator 16b can be a purely mechanical arrangement. The actuator 16b can include a lever 52b. The lever 52b can be engageable with gears of the actuator 16b.
Cranking of the lever 16b by a user can result in rectilinear movement of a rod 30b to move a cam 34b, to drive a pin 18b between an extended position and a retracted position relative to an open bed 12b.
100251 It is noted that the actuator 16, rod 30, sleeves 32, 132, and cam 34 are shown exposed in Figures 1 and 2, but can be enclosed within the frame 12 in one or more embodiments of the present disclosure. The actuator 16, rod 30, sleeves 32, 132, and cam 34 are shown disposed in a pocket 54 defined by the frame 14 in Figures 1 and 2. One or more panels can be releasibly engaged with the frame 14 to shield the actuator 16, rod 30, sleeves 32, 132, and cam 34.
[0026] Figure 7 schematically illustrates another exemplary embodiment of the present disclosure. A trailer 10a can include an open bed 12 supported by a frame (not visible). A first actuator 16c can be mounted on a first side of the frame. A
second actuator 116c can be mounted on a second side of the frame.

[0027] The exemplary actuators 16c, 116c can be electronically-controlled valves and be connected to a source of pressurized fluid 56c. The source of pressurized fluid 56c can be associated with a tractor/truck 58c operable to pull the trailer 10c. A

The controller 60c can be positioned in the tractor 58c to be operated by a driver of the tractor 58c. The driver can operate the controller 60c through a button, a switch, a knob, through voice commands, or some other modality. The controller 60c can control one or both of the valve-actuators 16c, 116c to open and thereby direct fluid to the pins 18c, 118c and the other pins. Lines 64c, 164c, and 68 represent fluid lines. Lines 66, 166c, represent lines of electrical communication. Each pin can be disposed in a sleeve defining a fluidly sealed chamber. Each pin can thus define a fluid cylinder.
The driver can thus control the pins to move to the extended position through the controller 60c.
100281 Figure 8 illustrates another exemplary embodiment of the present disclosure. A rod 30d can drive a cam 34d to drive a pin 18d between a retracted position and an extended position. The pin 18d is guided in motion by a sleeve 62d. The cam 34d can define a sliding surface 36d. The cam 34d can be selectively engaged, disengaged and re-engaged with the rod 30d. The cam 34d can be received in a slot in the rod 30d.
the slot can define a bottom to prevent the cam 34d from sliding completely through the rod 30d. Apertures can extend through the rod 30d to the bottom of the slot.
Additional apertures can be defined in the bottom of the cam 34d. The apertures in the cam 34d can be threaded. The apertures in the cam 34d can be aligned with the apertures in the rod 30d. Threaded fasteners, such as fastener 70d, can be received in the apertures in the rod 30d and threadingly engaged the apertures in the cam 34d to selectively engage the rod 30d and the cam 34d together. This allows the cam 34d to be replaced with another cam if another pattern of movement of the pin 18d is desired.
