Abstract

A securing device for a pair of double door such as a patio door; the device comprising a housing 1 which covers the two door handles with a retaining means to brace both handles together preventing either handle from being rotated. Preferably the device comprising one retaining flange 4 located behind a first handle and a securing pin through a hole 3 secures a second handle and keeps the device in place. In an alternative embodiment the device may comprise of two retaining flanges, the device being in two parts secured by a single retaining pin. There may be a plurality of holes 3 allowing adjustment to fit a range of door handles.

Description

Patio Door Security Device This invention relates to a device for securing a pair of handles on UPVC double! patio doors --Many modem UPVC double/patio doors now incorporate a multi-point locking system for security.The lock is usually a key operated euro style lock.

However, intruders have become increasingly competent in overcoming and disarming this type of lock (different methods of picking or snapping the euro style lock have been placed on the lnternet).Once the lock is picked or snapped the external handle can be pushed downward to release the multi-point locking system thus allowing access to the property. Also, in some doors where there is no retaining hook built into the locking system the doors can potentially be wedged/prized apart and pushed/pulled open to allow entry to the property.To overcome these problems the present invention proposes a removable securing bar for locking and bracing a pair of double/patio door handles together in a horizontal position, a retaining means for holding the securing bar in position.

The retaining means is preferably a retaining flange for one handle and a retaining pin for the other, but this could be achieved by alternative means, for example, by the use of a retaining pin, or clasp, for each of the handles.

The invention will now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 shows the securing bar 1 encasing a pair of double door handles with the retaining pin 2 in position.

Figure 2 shows a rear view of the securing bar 1 with the retaining pin 2 in position and the retaining flange 4.

Figure 3 shows a cross-section view from above of how the securing bar 1 is placed into position to encase the handles following the direction of the arrows Figure 4 shows a cross-section view from above of the securing bar 1 in its final position encasing the handles.

Figure 5 shows an alternative embodiment of the securing bar 1 and alternative arrangement of the retaining means.

In Figure 1 the main body of the securing bar 1 is shown encasing a pair of handles on double/patio doors and secured in place by means of a retaining pin 2 Once the interior handles are encased in this manner the exterior door handles cannot be turned since they are connected to the interior handles that are secured in the horizontal position by the security bar 1. Arranged in this manner the external handles cannot be operated or turned to release the multi-point locking system even if the euro style lock is picked or removed.

The securing bar 1 would ideally be constructed from a material of adequate tensile strength and gauge to maintain its structural integrity under high impacts and forces. The securing bar 1 would be of adequate dimensions to encase a range of door handles since there is variation in door handle design.

The internal body of the securing bar 1 would preferably be treated with a plastic or foam coating to avoid scratching the door handles, the coating would also minimize rattling and offer a closer/tighter fit to the handles.

In figure 4 the cross-section view from above shows how the securing bar 1 encases the handles and is retained in position by the retaining flange 4 and retaining pin 2. The retaining flange 4 butts up to the stem of the first handle and keeps the securing bar 1 held in position over this handle. Over the second handle a series of retaining pin holes 3 located in the securing bar 1 allow the retaining pin 2 to be inserted and hold the securing bar 1 in position over the second handle. There are a number of retaining pin holes 3 which allow for the retaining pin 2 to be fitted as close to the stem of the handle as possible (a number of holes would be included to allow for adjustment as some handles will be closer or further apart depending on their design). The retaining flange. 4, and the retaining pin 2 arranged in this manner to the stem of the handles brace the handles together if there is an attempt to wedge/prize the doors apart (e.g. where the locking mechanism does not incorporate a hooking mechanism).

The use of a retaining pin3 allows for easy and quick removal of the securing bar 1 in case of emergencies, for example, a house fire.

Figure 3 is a cross-section view from above and shows how the securing bar 1 is maneuvered into position encasing the internal handles. Using the arrows as a guide the securing bar I is first moved from left to right ensuring the first handle slides in between the securing bar 1 and the retaining flange 4. Once the retaining flange 4 meets the stem of the handle the right hand arrows indicates the security bar 1 is then rotated toward the door encasing the right hand handle.This procedure can be reversed; fitting from right to left since the securing bar 1 can be flipped over and attached from either direction.

In figures an alternative embodiment of the securing bar 1 is shown. The securing bar I is comprised of two parts. A and B, where B slides over A to form a continuous unit.A and B each incorporate a retaining flange 4. A selection of retaining pin holes 3 placed on the overlapping section of parts A and B allow for a retaining pin 2 to hold them together. The overlapping section between parts A and B would be of sufficient length to form arid maintain a rigid structure able to withstand high impacts and forces. The two flanges 4 butting up to the stem of each of the handles brace the handles together if there is an attempt to wedge/prize the doors apart and hold the securing bar 1 in position over the handles. The retaining pin 2 holds parts A and B of the securing bar 1 together to form a single unit to encase the handles and secure them in a horizontal position.

Claims

Claims 1. A securing device for a pair of UPVC double/patio door handles comprising a security bar of adequate dimensions to encase a pair of door handiles and hold them together in a horizontal position, and a retaining means such that the securing bar can be attached to and brace the handles together.
2. A securing device according to claim 1, in which the retaining means is provided by one retaining flange, one retaining pin and retaining pin holes.
3. A securing device according to claim 1, in which the retaining means is provide by two retaining flanges, one retaining pin and retaining pin holes.
4. A securing device accordingto any of the proceeding claims, in which the retaining means is adjustable.
