Abstract

A multi grip quick release tool head for use with a hand operated manipulator for use in manipulating locks and latches on a locked door from outside a building in order to gain access to the building; the tool head comprises a plurality of spring loaded / tensioned parts e.g. pins or rods A2, A2.1, that mould themselves around an object, such as a door latch, handle or lock of a security locking system, allowing the object to be manipulated. The pins A2, A2.1 are encased within a block A4 that has a quick release attachment means A6. Preferably the pins A2, A2.1 may be interchanges, to allow pins of different shapes or with different gripping means (fig 6) to be used to change the configuration of the pins A2, A2.1. The gripping ends of the pins may be chamfered A2.1, knurled (A1, fig 6) or coated with rubber. The pins are preferably contained within piloted chambers (A12, fig 7) within the block A4, which may be angled or straight.

Adjustable Tool-Head

Background

This tool has been invented & prototypes built to enhance the services of a Locksmith, The Police, Fire or Emergency Services or anyone authorised to gain permitted' entry to locked buildings without damage where possible.

Problem Solved In conjunction with specific locksmiths equipment, this innovative tool-head allows a trained technician to gain permitted access to numerous high security commercial or domestic premises where the owners have mislaid their keys or entry is required by the owners under different circumstances or in a case of an emergency such as afire, gas leak or where the inhabitants may be in danger or incapacitated.

What does the tool do? The tool-head is designed with movable parts that are able to mould around different shaped low & high security locking mechanisms such as deadlocks, security chains, bolts, handles & other locks.

Used with specific locksmiths' tools, the tool-head allows a relatively unskilled technician to be able to enter a secure premises both quickly & efficiently with great ease, leaving most locks & security applications undamaged with no sign of forced entry. In covert' situations, the tool-head a5sists with exiting the building & locking up behind you without anyone knowing that you've been there.

A multi grip universal tool-head encompassing a variety of movable spring loaded pins (AS) securely encased in a durable block (A4) with a quick release hexagonal turning bolt (A6). When engaged into position, the pins reconfigure their static clu5ter & are able to manipulate numerous security locking systems on the inside of the building whilst working from the outside when attached to a locksmith's tool which can be used by either locksmiths or members of the emergency services or public servants' such a military personnel involved in gaining entry to secure buildings where needed. This then allows the userto open locks, windows, manipulate handles, thumb turns, keys or other security applications.

The tool-head is designed to be inserted into a chuck head & its distinctive shape permits entry through small holes.

Figures 1 & 2 (Drawing 1 of 4) Drawing 1 shows the tool-head (figures 1 & 2) from a side on position & shows it together with its component parts albeit in a basic form.

2. Figure 3 (Drawing 2 of 4) Drawing 2 shows figure three as If looking down onto the leading head of the tool 3. Figure 4 (Drawing 2of4) Drawing 2, figure 4 depicts the tool-head from tie end view 4. FIgureS (Drawing2of4) Drawing 2, figure 5 displays the tool from the bottom end highlighting the bottom plate ((As) securing pins (Al).

5. FigureS (Drawing 3of4) Drawing 3 illustrates figure 6 and shows ar array of cylindrical pins outside of the tool-head arrangement, all of which are different in their make-up most notably at the top end which protrudes out of the head of the tool.

6. Figure? (Drawing4 of 4) Drawing 4, figure 7 shows the internal works of the tool-head In a little more detail with the pins in situ and the springs in different states of play in the housing chambers (A12). The housing chambers (A12) are counter bored so as to hold the foot of the pins (All) demonstrated on drawing 3 of 4, figure 6.

An example of the invention will now be described by referring to the accompanying drawings: Figure 1 & figure 2 on page 1 shows the side view/s of the Multi-grip tool-head which is designed to connect to a locksmiths tool via the quick release functional shaft/bolt (AG). The quick release functional shaft/bolt (A6) connects to the bottom of the multi-grip tool-head through the bottom plate (AS) via its threaded tail piece (A9) as is further secured by the split pins (A7). The multi-grip tool-head block (A4) houses a number of different cylindrical pins (Al, A2 & A2.l) which are set into the chosen piloted chambers (Al2). The Piloted Chambers (A12) are counter bored to accommodate the foot of the pins (All) securing them into place once the springs (As) have been inserted into each chamber (Al2) containing the pins (Al, A2 & A2.l).

Figure 3 on page 2 shows a top view of the block (A4) with the pins (Al, A2 & A2.1) in situ. It's important to note that the pins can be moved around to accommodate different applications according to the complexity of the job in hand.

Figure 4, page 2 shows the block (A4) end view again with the pins engaged in their static state/cluster secured by the bottom plate (AS) with the quick release functional shaft/bolt (A6).

Figure 5, page 2 shows the bottom view of the block (A41 covered by the Securing plate (As) and further held in place by the split pins (A7) & the quick release functional shaft/bolt (A6).

Figure 6 of page 4 shows the different types of pins used. Al' signifies a number of pins which are knurled at the contact' end as opposed to the end with the foot (All). The A2' type of pin is without the knurled effect but is finished as bull-nosed' or similar finish whereas the A2.l' type has a slightly chamfered end with a rubberised tip.

Figure 7 of page 4 shows a bigger vart' cross section drawing of the block {A4) and in particular shows that some of the chambers (Al2) are angled and some are straight. Figure 7 depicts the pins (Al, A2 & A2.l) in various stages of their movement & confirms the positioning of the springs (A8). Looking at the pin (A2.l) on the far left of figure 7 demonstrates that the foot (All) has stopped the pin, wedging itself into the widest upper point of the chamber (Al2) which is the natural static position for all pins (Al, A2 & A2.l) whilst not in use.

Figure 7 on page 4 illustrates that the chambers (A12) permit slight movement of the pins (Al, A2 & A2.l) from side to side as well as up & down.

Particular Examples

1. Working from the outside of a building & using the tool-head in conjunction with a locksmiths tool you're able to pass through a small opening such as a letterbox or window fanlight & unlock many types of door handles, deadlocked latches & numerous other security applications such as all types of thumb turn & nightlatches too.

2.

Detailed outline of the invention With such an array of high security locks, doors and access control entry systems/units, Iocksmiths or trained members of the Emergency Services often come up against extremely difficult situations when asked to gain entry to premises in a timely manner without causing costly damage to the doors or locks. The multi-grip tool-head has been designed to work with a locksmith's tool to help overcome a number of low & high security doors/applications.

The mu/ti-grip tool-head moulds its shape with the slightest of pressure. When pushed onto an object, it quickly changes its form by accommodating the pressure via the spring loaded pins thus moulding itself around locking mechanisms including all types of thumb turns, latches, handles & keys.

Used in conjunction with a Locksmiths Too! the multi-grip tool-head does the following: 1. If a client has deadlocked a uPVC door and left the key on the inside of the door/Euro cylinder, a different attachment will then let you turn the key from the inside but working from the outside of the door extreme!y easily, thereby gaining entry within seconds.

2. The tool-head also lifts or pulls down Drop Snib' locking systems on night latches on the inside of the building whilst working from the outside of the building, without having to remove the tool or adjust the head.

3. The multi-grip Tool-head lets you push, mould, engage & unlock the centre door locking knob on a WEISER & Union Knob Set' thereby unlocking the door, again on the inside but working from the outside of the premises.
