Abstract

The apparatus comprises a channel-like construction (1 Figure 1) within which two bar members 8 move in opposite directions, which bars can be locked by a key or handle-operated mechanism consisting of handles 7. The ends of the bars are driven into reception enclosures 9, 10. <IMAGE>

Description

PASSAGEWAY ACCESS BARRING APPARATUS This invention relates to a passageway access barring apparatus.

Devices for barring an entrance such as a door or window are by no means novel, with locks, bolts and bars being the most common example of such access barring devices. The problem however, with tnese types of devices, is that the greater the degree of security needed to be imparted by them, the greater the need to increase the strength of their constructional elements. This increased constructional element strengthening usually resulting in a substantial increase in weight. This can cause them to become both heavy and cumbersome in terms of both their initial installation, and subsequent operation. A classic example being the use of a horizontal bar to span a door and its frame. In operation this horizontal bar has first to be lifted and then bodily man-handled into two receptor seatings, normally door frame mounted lugs, situated at either side of the door frame.

The operation of such a door barring device can prove to be a tiring, and for some people a physically dangerous task, to embark upon. Indeed some door locking devices in common use today can actually weaken the door and its frame, as in the case of mortice locks. This is caused by the need to remove a fairly substantial amount of material fro both the door and the door frame during the installation of such locks.

According to the present invention there is provided a passageway access barring apparatus comprising a body in the form of a channel section, two slidable internal locking bar members, means by wnich these slidable internal locking bar members can be extended and retracted, means by which these slidable internal members can be placed in a locked and unlocked state, means for the actuation of such locking bar member locking mechanisms, means for the positioning, location and retention of the overall passageway access barring apparatus body construction.

A specific embodiement of the invention will now be described by way of example with reference to the accompanying drawing in which Figure 1 illustrates an exploded view of the passageway access barring apparatus internal element construction relationships.

Figure 2 shows in perspective, the passageway access barring apparatus in position.

Figure 3 shows in perspective, the passageway access barring apparatus constructional element aperture locations.

Figure 4 snows the locking bar motion activation mechanisms.

Referring to the drawing the door or window barring apparatus comprises a channel like housing construction ( 1 ), within which two locking bar members ( 2 ), traverse in a free but restricted manner, means for the retention, location and guidance of these bar members, means for the reception, location and retention of the aforementioned bar member end sections, means for the releasably locking of said bar member ends ( 3 ), in their respective reception enclosures, as described in Figures 1 and 5.

The passageway access barring apparatus housing construction is mounted on the access port to be protected, in this particular instance a door ( 4 ), in such a manner as to impart the greatest possible degree of additional strengthening to the door and its framework, at the point of greatest potential weakness, usually the point at which the door is opened in relation to its frame, as described in Fig 2.

The body of the passageway access barring apparatus locking bar member construction, is manufactured from a suitably rigid and robust material. The external housing body construction of this passageway access barring apparatus, to be manufactured in such a way as to provide an internal enclosure, in the form of a channel or the like. This internal enclosure to then provide the location, retention and guidance means for the two internally slidable locking bar members. This interlocking and slidable arrangement to be so designed as to allow free, but restricted travel of the locking bar members, within the overall length of the passageway access barring apparatus body construction. The exact shape of the passageway access barring apparatus internal enclosure dictated by the form and shape of the internal slidable members themselves.

Further openings and orifices ( 5 & 6 ), are provided throughout the length of the passageway access barring apparatus body construction to accomodate the location of the internal locking bar members motion activation and locking means, as described in Fig 3.

In order to initiate the passageway access barring apparatus procedure, the door is first fully located within its door frame.

Then the passageway access barring apparatus's internal locking bar members are propelled in opposite directions with respect to each other within the locking bar housing body, by means of either a key operated locking bar member activation mechanism, or by means of a manually operated locking bar member activation system, in this particular instance two handles ( 7 ), situated on the locking bar members own body construction. This opposable locking bar member motion, has the effect of driving the end section of each locking bar member ( 8 ), into its own respective reception enclosure ( 9 & 10 ), which may be situated on either tne door, tne door frame, or the door frame own support elements i.e. a wall, or floor, as described in Fig 4.

Once the locking bar members have been fully extended and their ends sections firmly located within their respective reception enclosures, the locking bar members can then be locked in position by means of either a key operated lock, or by manually operated lock devices such as a bolt, pin etc ( not shown ).

In order to deactivate the system the operations outlined above are reversed, with the extendable locking bar members being fully retracted and held in position by the same locking means, when the door is in normal operation.

This door bar locking member arrangement now provides the door and its framework with a considerably strengthened overall rigidity, with little or no removal of the doors own existing material, coupled with desirable attributes of increased ease of installation, maintenance and removal of said device, by comparitively unskilled personnel.
