Tube restraint and methods
View Patent ↗Devices for restraining tubular segments and methods for storing and accessing tubular segments may include a frame arrangement that has a plurality of parallel cradles for holding tubular segments and movable restraining handles for securing the tubular segments. A spring retention assembly may also be provided that has a spring force to hold the restraining handles against the tubular segments. A vehicle can be equipped to have a device for storing and accessing tubular segments, wherein the device is movable between a storage position and an access position.
1. A storage mechanism for holding and securing at least one tubular segment, the storage mechanism comprising:
(a) a frame arrangement defining at least a pair of open ended cradles for holding a tubular segment;
(b) at least one restraining handle, the handle being connected to the frame arrangement and movable between a storage position and a release position;
(i) the storage position including the handle extending over at least one open ended cradle thereby securing the tubular segment to the frame arrangement;
(ii) the release position including the open ended cradle being free of coverage by the handle, thereby allowing the tubular segment to be removed from the frame arrangement; and
(c) a spring retention assembly, the spring retention assembly having a spring force that holds the restraining handle against the tubular segment when the restraining handle is in the storage position;
(d) a locking mechanism to prevent the restraining handle from moving out of the storage position; and
(e) a support bracket assembly pivotally connected to the frame arrangement to allow the storage mechanism to pivot about the support bracket assembly.
2. The storage mechanism of claim 1 , wherein the locking mechanism has a locked position and an unlocked position and is engaged in the locked position when the restraining handle is in the storage position and wherein the locking mechanism is disengaged in the unlocked position when the restraining handle is longitudinally displaced away from the cradles.
3. The storage mechanism of claim 2 , wherein the locking mechanism comprises:
(a) at least one protrusion member located on the restraining handle; and
(b) at least one recess that is defined by a fixed portion of the frame arrangement;
(c) wherein the locking mechanism is engaged in the locked position when the protrusion member is engaged within the recess; and
(d) wherein the locking mechanism is disengaged in the unlocked position when the protrusion member is drawn out of the recess.
4. The storage mechanism of claim 3 , wherein an end of the protrusion member is constructed and configured to slide across the outer face of a first plate when the locking mechanism is in the unlocked position, the first plate defining the recess of the fixed portion of the frame arrangement, wherein the spring force of the spring retention assembly provides a frictional force between the protrusion member and the outer face of the first plate.
5. The storage mechanism of claim 4 , wherein the compression spring assembly further comprises a compression spring and a second plate, the retaining plate being longitudinally secured to a stem of the restraining handle by a stem protrusion, wherein the compression spring is compressed between the first and second plates.
6. A vehicle having a storage mechanism for holding and securing at least one tubular segment, the storage mechanism comprising:
(a) a frame arrangement defining at least a pair of open ended cradles for holding a tubular segment;
(b) at least one restraining handle, the handle being connected to the frame arrangement and movable between a storage position and a release position;
(i) the storage position including the handle extending over at least one open ended cradle thereby securing the tubular segment to the frame arrangement;
(ii) the release position including the open ended cradle being free of coverage by the handle, thereby allowing the tubular segment to be removed from the frame arrangement;
(b) a spring retention assembly, the spring retention assembly having a spring force that holds the restraining handle against the tubular segment when the restraining handle is in the storage position;
(c) the storage mechanism being mounted to the vehicle and movable between a storage position and an access position;
(i) in the storage position, the cradles and the restraining handles generally facing a surface of the vehicle; and
(ii) in the access position, the cradles and the restraining handle generally facing away from the surface of the vehicle;
(d) a locking mechanism to prevent the restraining handle from moving out of the storage position; and
(e) a support bracket assembly fixed to the vehicle and pivotally connected to the frame arrangement to allow the storage mechanism to pivot about the support bracket assembly.
7. The vehicle of claim 6 , wherein the storage mechanism is pivotable relative to the support bracket assembly about an axis generally parallel to the longitudinal axis of the vehicle.
8. The vehicle of claim 6 , wherein the locking mechanism is engaged in a locked position when the restraining handle is in the storage position and wherein the locking mechanism is disengaged in an unlocked position when the restraining handle is longitudinally displaced away from the cradles.
9. The vehicle of claim 8 , wherein the locking mechanism comprises:
(a) at least one protrusion member located on the restraining handle; and
(b) at least one recess that is defined by a fixed portion of the frame arrangement;
(c) wherein the locking mechanism is engaged in the locked position when the protrusion member is engaged within the recess; and
(d) wherein the locking mechanism is disengaged in an unlocked position when the protrusion member is drawn out of the recess.
