Description

Protective device and method against break in

The present invention relates to a break-in prevention for obstructing an attempt, by means of sliding a shimmying member such as a flexible sheet material into a lock of a bolt, such as a latch bolt, slidable into a closing opening, such as in a closing plate or closing cavity, to open a lock of a movable closing element in the form of a door or window arranged in a wall or frame in the wall, wherein the closing element is arranged in a closed state against an edge. The present invention also relates to a method for manufacturing such a break-in pre^¬ vention. The present invention can be generally applied in closing systems comprising a wall, preferably provided with a window frame and/or doorjamb, with a closing element in the form of a door or window.

Many ways of gaining unauthorized access through doors and/or windows are known. One of these unauthorized ways of gaining access is known as so-called shimmying. Shimmying is possible when a door lock is provided with a latch bolt which is angled on one side so that the door can be closed easily. Shimmying is an act wherein access is gained to this latch bolt by means of a deformable sheet material, such as even a normal bank card or credit card, wherein by pressing against the angled side the latch bolt is urged into the lock, wherein it slides out of the closing opening such as in the closing plate or the closing cavity.

Shimmying can be prevented per se in many ways, these however requiring structural modifications to the closing systems or considerable investment. It is thus possible for instance to apply a central lock, the central lock having measures incorporated to prevent shimmying. Another solution effectively preventing shimmying per se is the use of a latch bolt in addition to the so-called dead bolt, although this requires separate operations by the user of the lock during each closing action and each opening action.

In order to obviate these drawbacks of the prior art the present invention provides a break-in prevention for obstructing an attempt, by means of sliding a shimmying member such as a flexible sheet material into a lock of a bolt, such as a latch bolt, inserted into a closing opening, such as in a closing plate or closing cavity, to open a lock of a movable closing element in the form of a door or window arranged in a wall or frame in the wall, wherein the closing element is arranged in a closed state against an edge, the break-in prevention comprising:

- a mounting element for mounting thereof on the frame or the closing element, wherein the closing element is arranged in a closed position in the frame, and

- a retaining element for preventing the shimmying member being able to reach the bolt;

- wherein at least the retaining element is coupled to the mounting element such that the retaining element functions at the position of the closing opening for the bolt for the purpose of obstructing sliding of the bolt into the lock.

An advantage of a break-in prevention according to the present invention is that, by means of a simple placing operation, an effective safeguard against shimmying is provided without further modification to the closing sys- tern. Assuming a clearance of 1-3 mm between the frame and the end surface of the door, such a provision can be easi^¬ ly arranged without problem and without additional opera^¬ tions during use by means of for instance an adhesive ac- tion and/or inserting one or several screws or nails. A further important advantage of the prevention according to the present invention is that it can be manufactured in simple manner and at low cost. A further advantage of a prevention according to the present invention is that it can have a low weight and can therefore be easily distrib^¬ uted. A further advantage of a prevention according to the present invention is that it can be arranged by practically any end user of the closing system him/herself without a professional specialist being necessary.

According to a first preferred embodiment according to the present invention, the break-in prevention is con^¬ figured for mounting on the frame, wherein the mounting element and the retaining element comprise a sheet materi^¬ al, preferably comprising a spine part, more preferably formed by means of a fold in the sheet material. The stat^¬ ed advantages of easy arrangement and convenience of use also apply in this preferred embodiment.

According to a further preferred embodiment, the break-in prevention comprises at least one hook element for providing an intercepting action relative to the shimmying member. When shimmying is attempted, the latch bolt is usually approached from the upper side or the underside by the shimmying member. The hook elements provide for this purpose an effective engagement on the shimmying mem^¬ ber so as to prevent a further movement in the infeed direction .

At least one hook element more preferably has an engaging action here on the shimmying member in a longitudi^¬ nal direction of the frame.

According to a further preferred embodiment, the mounting element and/or the retaining element are manufac^¬ tured from a metal such as a steel, such as spring steel. When such materials are applied simple manufacture is possible by means of a punching operation on the metal. A very strong retaining element is hereby provided, and it also becomes possible to manufacture the device in highly advantageous manner.

The mounting element and/or the retaining element are more preferably manufactured from a plastic such as polypropylene or polycarbonate, more preferably from rubber. Operations for manufacturing from a sheet material are provided using such materials. Also envisaged is forming of the device by means of such materials by means of a forming operation such as moulding or in ection moulding.

Envisaged in each preferred embodiment is that use is made of a reinforcement, such as a fibre reinforcement.

For mounting purposes the break-in prevention more preferably comprises mounting means such as comprising an adhesive. The break-in prevention can hereby be arranged on the doorjamb or the frame as if it were a sticker.

A mounting is provided in alternative manner by means of mounting means such as openings for the purpose of passage of mounting materials such as screws, nails or nuts. These mounting means are provided in alternative manner as addition to mounting by means of an adhesive.

A further preferred embodiment according to the pre^¬ sent invention relates to such a break-in prevention, comprising a body of which the mounting element and the retaining element form part, wherein

- the mounting element is configured for mounting on a closing element on a first side thereof, and wherein

- in mounted position of the body the retaining ele^¬ ment extends from the closing element in the direction of closure of the closing element.

This embodiment is provided particularly for appli- cation on the closing element, such as the door or the window itself. Particularly in situations wherein a so- called draught strip is arranged in the frame there is space behind the draught strip for placing of a retaining element according to the present embodiment.

Such a break-in prevention more preferably comprises a second mounting element for making contact with a second side of the closing element. An easy stop is hereby provided in simple manner for positioning purposes. The second mounting element also provides a contact surface for applying an adhesive in a second mounting direction relative to the closing element. A firm mounting is realized by applying two adhesive surfaces at a mutual angle of about 90°.

According to a further preferred embodiment, the mounting element, the retaining element and/or the body are manufactured by means of a forming operation such as moulding or in ection moulding.

The mounting element more preferably forms part of a closing plate arrangeable in the wall, the frame or the door amb, and wherein the retaining element extends from the mounting element or the closing plate. By means of such a preferred embodiment a smaller clearance is possi^¬ ble between the closing element and the wall.

In a further preferred embodiment the mounting ele^¬ ment is provided with a barrier element for blocking the shimmying member. A movement of the shimmying member in the direction of the bolt of the lock is prevented in additional manner by means of the barrier element.

The barrier element is more preferably formed by means of punching a periphery thereof out of material of the mounting element and arranging thereof at an angle relative to the mounting element, preferably by means of a folding operation. The barrier element can on the one hand hereby be manufactured in advantageous manner and the strength of the barrier element is on the other greatest at the position of the mounting element, precisely where the shimmying member exerts the greatest forces. Through such a forming of the barrier element the shimmying member is further urged precisely in the direction of this posi^¬ tion where the strength is greatest before the forces become considerably greater due to the blocking.

According to a further preferred embodiment, the break-in prevention comprises a guide member for guiding the shimmying member from the retaining element in the di^¬ rection of the mounting element. The guide member is more preferably formed by means of bending an end part of the retaining element. This guide member achieves that a shim^¬ mying member is urged in the direction of the mounting elements. The shimmying member is hereby better obstructed by the retaining element and the shimmying member is also better obstructed by the barrier element. The combination of barrier element and guide element therefore provides a surprising combined effect.

A protruding corner of the retaining element is more preferably provided with a finished corner, wherein the finish reduces cutting into clothing or the skin, preferably by means of a curvature gradient in one or preferably two directions. The user-friendliness of the device is hereby increased, and damage or inconvenience prevented.

A cutting surface is arranged in a corner between the mounting element and the retaining element. This cut^¬ ting surface achieves in advantageous manner that the shimmying member is damaged and/or that material is re^¬ moved therefrom during shimmying. This achieves that such material can be used as evidence against an operator of the shimmying member.

A further aspect according to the present invention relates to a method for manufacturing a break-in prevention, comprising steps for:

- defining the periphery of an assembly of mounting element and retaining element,

- punching the assembly of mounting element and re^¬ taining element from a sheet material,

- forming a spine part by means of an operation such as bending or folding, wherein the mounting element and the retaining element are formed on either side of the spine part. This aspect provides advantages as described with reference to another aspect according to the present invention .

Further advantages, features and details of the pre^¬ sent invention will be described in greater detail herein- below on the basis of one or more preferred embodiments with reference to the accompanying figures. Similar, though not necessarily identical components of different preferred embodiments are designated with the same reference numerals.

Fig. 6 shows a perspective view and top view of the preferred embodiment according to Fig. 4 and 5. Fig. 7A, B show two perspective views of a further preferred embodiment according to the present invention.

A first preferred embodiment (Fig. 1-3) according to the present invention relates to a break-in prevention 1. This comprises substantially two step-like elements, a mounting plate 2 and a retaining plate 4. In this pre^¬ ferred embodiment the retaining plate is divided into three parts, retaining plate 4 for arranging close to the closing opening, and two sub-retaining plates 4'. An adhe- sive strip 7 is provided for attachment purposes on the rear side of mounting plate 2. Also provided are four openings 9 for arranging screws therethrough, this being an optional operation. If for instance screws are applied, the adhesive strip is an optional measure.

Provided in the approach direction of the shimmying member are recesses 8, 8', 10, 10' for the purpose of serving as hook elements for intercepting the shimmying member. When the shimmying member approaches the break-in prevention from the upper side or the underside, it will be intercepted in the relevant recess.

By way of illustration hereof shimmying member 25 is shown in Fig. 3. Door 22 is shown in an almost closed position relative to frame 21. In this position the door can be further closed in the direction of arrow A, after which latch bolt 14 will move in the direction of arrow B into closing opening 16.

Retaining member 4 is mounted on the frame by means of an adhesive strip 7. When the door is closed, the door will cause the retaining member to yield to some extent. The shimmying member is inserted between the side 22' of door 22 and the side 23 of the frame. In order to be able to reach the latch bolt the shimmying member has to be pressed round the door, wherein it will come up against and be stopped by retaining member 4, and would not therefore be able to reach the inclining side of the latch bolt .

An unauthorized attempt at access is hereby blocked in effective manner by applying the break-in prevention with the retaining member according to the present invention .

The preferred embodiment according to figures 4-6 relates to a break-in prevention 31 comprising a mounting plate 32, a sub-mounting plate 35 extending substantially perpendicularly of mounting plate 32 and a retaining member 34 extending substantially in line with mounting plate 32. Mounting plate 32 and sub-mounting plate 35 are attached by means of adhesive strips 7' to the edge of the door at the position of latch bolt 14 of the door lock.

This door can for this purpose be applied in a frame as shown in Fig. 3, since through use of the draught strip there is space for accommodating the retaining member in the frame when the door is closed. It is envisaged to ap- ply recesses on the outer end of retaining element 34 similar to the recesses of the above embodiment. It is also envisaged not to apply recesses in the embodiment accord^¬ ing to Fig. 1.

Fig. 7 shows two views of a further preferred embod- iment . Fig. 7B is a perspective view and Fig. 7A is a cut^¬ away perspective view. The mounting plate is provided in similar manner as in the above embodiments with screw holes 9 as well as an adhesive strip on the rear side thereof. Three retaining plates 4 are bent out of mounting plate 2.

Both outer retaining plates 4 are provided with a bent guide member 76. These guide members serve to guide a shimmying member in the direction of the mounting plate. A barrier element 73 is arranged somewhat beyond guide member 76 as seen from respectively the upper or underside during use. The barrier element intercepts a shim^¬ mying member when it is moved in the direction of the barrier element. Guide member 76 is also functional here since it guides the shimmying member into the barrier ele^¬ ment. The intercepting action of the device is hereby en^¬ hanced still further.

The bent corners 75 between the mounting member and the retaining element are preferably sharpened for the purpose of cutting material off the shimmying member when it is pulled along them. Particularly advantageous here is that material obtained from the shimmying member in this manner can serve as evidence in proving the involvement of the operator of the shimmying member.

The edge corners 75 of the retaining element are provided with a curvature in the plane of the material and are provided with a curvature perpendicularly of the plane of the material, whereby a rounded corner results, this rounded corner preventing cutting into the skin or damage to textile.

The present invention has been described in the foregoing on the basis of several preferred embodiments. Different aspects of different embodiments are deemed de^¬ scribed in combination with each other, wherein all combinations which can be deemed by a skilled person in the field as falling within the scope of the invention on the basis of reading of this document are included. These preferred embodiments are not limitative for the scope of protection of this document. The rights sought are defined in the appended claims.
