Abstract
A telescopic security post comprises at least two tubular sections 10, 12; an interlocking mechanism, eg slot and peg [15,16 Fig 3], for locating the tubular sections in an extended position; and a locking means to secure and prevent the post from being collapsed. The locking means comprises a rectangular block 18 attached by chain 21 to the base of the housing 13 and to the top tubular section 10. The rectangular block 18 has a plurality of grooves for selectively engaging a slot in the top post member 10. By removing slack from the chain 21 and engaging the rectangular block 18 in the slot it is not possible for the tubular sections 10, 12 to be collapsed. A cylinder lock 17 is housed within the rectangular block 18 and is used to rotate lever 25 through ninety degrees so as to abut stop 26 and secure the rectangular block 18 in place.
Description
EXTENDIBLP POSTS.
This invention relates to an extendible post mainly used for protecting from theft motor vehicles by preventing them being driven away, there are a big range of posts available on the open market but these are limited to posts that are hinged at ground level and posts that are completely lowered into the ground, the later makes it necessary to excavate a hole deep enough to take the whole post depth..
According to the present invention the post is constructed of a number of interlocking sections that can be locked and secured together to form a rigid post. Equally they can be collapsed and lowered into the ground where the excavation depth to house the post can be relatively short.
A specific embodiment of the invention will now be described by the way of an example with reference to the accompanying drawings in which.
Figure. l. :-Shows a perspective of the post in the extended position.
Figure. 2. :- Shows a perspective of the post in the collapsed and covered position.
Figure. 3 :- Shows the interlocking mechanism of the tubular sections.
Figure. 4 :- Shows the security locking mechanism in the engaged position.
Figure. 5 :- Shows how the chain is anchored to the base plate.
Figure. 6 :- Shows the position of the locking mechanism in the
unlocked condition.
Refering to the drawing.
Fig 1 shows the post constructed of tubular sections 10,11, and 12. Section 10 is capable of sliding into 11 and section 11 is capable of sliding into 12. Section 12 is also housed in the lidded box 13.
In the collapsed position Fig 2 the sliding tubular sections are lowered
into a position where the lid 14 on box 13 may be closed over the collapsed sections 10, 11 and 13.
When the post is in it's working position as fig l. A interlocking mechanism is employed to prevent the tubular sections 10 and 11 returning to the collapsed position. The interlocking mechanism is in the form of a bayonet type action as shown in Fig 3. The slots 15 in section 10 extends downwards almost to the depth of section 10 but stops before reaching the end of section 10 and then moves laterally around the tubular section before moving upwards for small distance. This arrangement produces a slot in the form of a hook.
Fig 3 also shows a peg 16 on a broken away section, turned back for clarity attached to tubular sectionl 1 extending inwards to register in the hook part of slotl5. A similar arrangement of slot and peg occurs beteen tubular sections 12 and 13. When all the tubular sections are
located together by means of the slots and pegs, the method of securing
and locking them in the extended position is by means of the rectangular block 18 fig 5 and fig 6.
The rectangular block 18 can slide up and down through hole 22 but is prevented from passing through by cap 20 fig 5 and fig 6. This
rectangular block 18 is attached to the base of tubular section 13 by
chain 21 Fig 5 or any similar linked collapsible construction.
The rectangular block 18 also contains a groves 19 which allows the block 18 to slide across slot 24. In the vertical axis of the rectangular block 18 in a cylinder lock 17 which can turn lever 25 through 90 degrees.
Therefore the action to secure the post in the extended position is as follows :- The rectangular block 18 is pulled upwards to it's maximum extent and aligned with the respective grove 19 this then allows it to slide across slot 24 until it reaches the end of it's travel. The key is inserted in lock 17 and turned thereby turning lever 25 until it reaches stop 26. This action prevents the retangular block from returning along slot 24 and when the key is removed secures the post in the extended position.
It will be appreciated that the parts may be made of appropriate materials of metals, plastic or ceramic for example.
Claims (2)
- -CLAIMS 1 An extendible and collapsible post used for protecting motor vehicles from theft, comprising of two or more tubular sections that are capable of sliding within each other and that are held in the extended position by the use of a bayonet actions on the tubular sections, which are then locked in place by a chain preventing the tubular sections releasing from the bayonet action.
- 2 Apparatus as in claim I that takes up any slack on the chain by having a series of groves in a block thats fixed to the end of the chain and when the respective grove lines up with the slot on top of the post can slide along and a lockable lever can be turned via a key to prevent the block from returning thereby securing the post.
