Fastening Means

摘要

Fastening means, a preferred embodiment of which is shown in FIG. 2, hasajoist 1 and a locking member 5. The joist 1 has a channel and locking extensions and the locking member 5 has a base 6 and an upstand 7. The base 6 has rounded corners 10. The fastening means is formed such that when it is in use the locking member 5 can be slid into the channel and rotated therein to assume a locking position, such rotation made possible by the rounded corners 10 which, when in use, serve to prevent a rotational impasse between the joist 1 and the locking member 5. The fastening means is formed such that when the locking member is in the locking position it is in a tight fit within the channel and cannot pull out of the channel by reason of obstruction by the locking extensions.

主权项

1. A walking surface having a fastening means comprising a beam and a locking member, the beam having a channel and locking extensions, the locking member having a base and an upstand, the base having reduced corners, the fastening means formed such that when it is in use the locking member can be slid into the channel and rotated in a first direction therein to assume a locking position, such rotation made possible by the reduced corners which serve to prevent a rotational impasse between the beam and the locking member, the fastening member being in a tight fit within the channel and unable to pull out of the channel by reason of obstruction by the locking extensions, the locking member being able to be released from the locking position only by rotation of the locking member in a second direction rotationally opposite the first direction, an item of walking surface board arranged such that it has been laid onto one of the locking extensions so that part of the locking member extends into a side groove of the board.
