Tie-down device
The present invention relates to a tie-down device comprising a base member and a retaining member, the retaining member having a plate and a pin extending from the plate, the pin being engageable with a part of a channel or structure associated with the channel, the plate being engageable with another part of the channel or structure associated with the channel by pushing the retaining member to a distal position away from the base member and twisting the retaining member whilst in the distal position into engagement with the channel or structure associated with the channel.
1. A tie-down device comprising a base member and a retaining member, the retaining member having a plate and a pin extending from the plate, the pin being engageable with a part of a channel by locating in a hole provided in the channel, the plate being engageable with another part of the channel by pushing the retaining member to a distal position away from the base member and twisting the retaining member whilst in the distal position into engagement with the channel.
2. A tie-down device according to claim 1 , further including:
a pair of spaced apart, co-planar and substantially parallel elements provided on the base member on either side of the retaining member; and
biasing means between the base member and the retaining member against which the retaining member acts in moving to the distal position, the parallel elements engaging the channel when the biasing means is at least partially released.
3. A tie-down device according to claim 1 , wherein the plate is elongated, having longer edges lying transverse to an axis of the base member and shorter edges lying approximately parallel to the axis, wherein twisting the plate through approximately ninety degrees results in parts of the plate proximate to the shorter edges engaging with the channel.
4. A tie-down device according to claim 2 , wherein the parallel elements engage in the channel under action of the biasing means to inhibit twisting of the device within the channel.
5. A tie-down device according to claim 2 , wherein the biasing means comprises one or more compression springs located between the base member and the retaining member that are compressed when the retaining member is pushed away from the base member and uncompress, returning the retaining member back towards the base member, when a pushing force acting on the springs is removed.
6. A tie-down device according to claim 2 , further including indicating means for indicating when any one or more of the pin, plate or parallel elements are not engaged with the channel.
7. A tie-down device according to claim 6 , wherein the indicating means includes visual indicia provided on the retaining member that is only viewable when the retaining member is in the distal position.
8. A tie-down device according to claim 1 , wherein twisting of the retaining member causes the plate to rotate within the channel through a specified angle, whereupon opposed parts of the plate engage with the channel to secure the device to the channel.
9. A tie-down device according to claim 1 , further including indicating means for indicating when any one or more of the pin or plate are not engaged with the channel.
