Description

Training door for door breaching
The present invention relates to a training door according to the introductory portion of the independent claim.
In particular, it relates to such a training door for training door breaching
Background of the invention
The police and rescue services need to rapidly enter locked doors in order to perform their tasks. This is performed by breaching doors using force and special techniques. To be able to do so, regular and realistic training is necessary.
In order to perform these training sessions, the police and rescue services each year need to purchase a large number of wooden doors. It is only possible to use each door a limited number of times as they break during the training. This gives large costs for purchase, administration, transport, discarding and recycling.
DE3531702 discloses training doors for door breaching. These training doors do however need a substantial reassembly after each forced entry, which is costly and time consuming.
An object of the invention is therefore to provide a training door which requires fewer and simpler steps between the forced entries.
An other object of the invention is to provide a training door which is able to reproduce how a real door would yield at forced entry in a more realistic way.
These and other objects are attained by a training door according to the characterising portion of the independent claim.
Summary of the invention
The invention relates to a training door with at least a door leaf, a frame 1 and at least one locking cylinder 3a-e arranged to lock the door leaf against the door frame. At least one locking cylinder 3a-e is provided with at least one fractural impression. The fractural impression advantageously gives a controlled break at a selected position, while remaining parts after forced entry return to the original state.
The training door advantageously further comprises a moveable frame 2 with openings for reception of at least one locking cylinder 3a-e, 10. The frame 2 is resiliently suspended in the frame. In a particularly advantageous embodiment, the resilient suspension is of varying strength at varying positions on the frame, in order to be able to resemble different kinds of real doors.
The invention further relates to such a training door provided with a forward feeding key 9 arranged to be received in a fractural impression, for controlled forward feeding of new locking cylinder pieces.
The training door may further comprise locking cylinders 10 that are resiliently suspended and arranged to be pressed against the door leaf when the door is forcibly entered, which advantageously resembles the properties of seven lever locks and nine lever locks at forced entry.
The training door may further comprise a fling protector 8.

Fig. 2 shows the training door in a rear view
Fig. 3 shows in greater detail the mid section of the training door in a rear view
Fig. 4 shows a forward feeding key
Fig. 5 shows part of the training door with a seven lever lock cylinder
Fig. 6 shows the long side of the training door that faces the door frame
Fig. 7 shows a rear view of the upper corner of the training door with fling protector Description of a preferred embodiment
Fig. 1 shows an embodiment of the training door in a front view, comprising the door leaf itself, a rigid frame 1 and a moveable frame 2. The door leaf hangs in the rigid frame 1 with four hinges 6a-d and is held against the moveable frame 2 by at least three illustrated slideable locking cylinders 3a, 3c, 3d. The moveable frame abuts or is in the immediate vicinity of the long side of the door leaf that faces the hinges. The moveable frame is held in place by five springs 5a-e and five bolts 4a-e that extends in an opening between the rigid frame and the moveable frame.
The door leaf, the rigid frame and the moveable frame are all substantially sturdier than a normal door leaf and frame would be, so at a practice force entry neither the frame nor the door leaf gives in or warps. The resilient suspension of the moveable frame, steered by the bolts 4a-e makes the frame give in in a reversible and controllable way that corresponds to the movements of a real door leaf and a real door frame when giving in to a forced entry. The bolts 4a-e and springs 5a-e are intended to steer the movement of the moveable frame in the direction of the horizontal extension of the door.
The slideable locking cylinders 3a, 3c, 3d extends through and may be slid through an attachment device on the rear side of the door leaf and further extends through a corresponding frame cylinder holder 13a-e. With the locking cylinders in this position, the door leaf is held shut and if force is applied to the door in an attempted forced entry, the slideable locking cylinders are exposed to a bending force. The locking cylinders a provided with equidistant fractural impressions along the extension of the locking cylinders, visible in the figure a transverse lines. The training door is designed such that such a fractural impression naturally is positioned where the moveable frame and the door leaf meet, such that the bending force is applied to the fractural impression. When a sufficient force is applied to the training door, the locking cylinder is broken at the fractural impression and, depending on which kind of real door the training door is intended to imitate, the door may be opened after all the locking cylinders have been broken in relevant order.
The springs 5a-e then makes the door frame return to the original position and since the rigid door frame and the door leaf are rigid, the door may immediately be shut without having more that cosmetical damages due to the forced entry. Fig. 2 shows the training door in a rear view and here the slideable locking cylinders 3a, 3c, 3d are illustrated in their full length. The locking cylinders may unused have a length nearly corresponding to the width of the door leaf and are provided with fractural impressions along their full length. The fractural impressions are turned slits that may be produced with a width and depth corresponding to the required breaking strength.
The locking cylinders extend through U-shaped openings in the frame that in conjunction with the frame cylinder holders 13a-e constitute a closed opening around the cylinders ends. The opening is a through hole such that the cylinders may be pushed out of the opening at feeding of the cylinders one step forward to the next fractural impression. The frame cylinder holders are also held in place by springs 7al-el, 7a2-e2, such that the door leaf is given a resilient range of movement in the direction it is forcibly entered, in a way intended to correspond to how a normal door and door frame would warp during forced entry.
Both the springs 5a-e acting in direction of the horizontal extent of the training door may have varying spring length and strength and the springs 7al-el, 7a2-e2 acting in the direction that the door is opened may have varying spring length and strength. In this way a large degree of freedom is given to control the response of the door to forced entry such that different kinds of real doors may be emulated.
Fig. 3 shows in greater detail the mid section of the training door in a rear view and here is illustrated, in addition to the mid locking cylinder 3c, a seven lever lock cylinder 10 and an attachment device 1 Id and a reception opening 12d for a nine lever lock cylinder. The seven lever lock and nine lever lock cylinders are attached in the same way and may slide freely in their respective reception opening and attachment device, but as opposed to the other locking cylinders are pressed into the reception openings by a spring 14 and correspondingly extend into the moveable frame. At forced entry, The seven lever lock and the nine lever lock cylinders shear and the spring suspension allows them to be pushed out of the frame and loosen in a way similar to how real seven lever locks and the nine lever locks would act at forced entry.
The seven lever lock cylinder 10 is arranged between the mid locking cylinder 3c and the upper locking cylinder 3 a, that is at the same position a real seven lever lock would be placed. In a corresponding way, the nine lever lock cylinder is arranged between the mid locking cylinder 3c and the lower locking cylinder 3e, that is at the same position a real nine lever lock would be placed. This positioning is also intended to resemble the behaviour of a real door provided with such locks.
In the figure a forward feeding key 9 is also illustrated in conjunction with the attachment of the mid locking cylinder 3 c at the long side of the door leaf. The forward feeding key is slid into a groove in the attachment and extends into a fractural impression. In this way another fractural impression is held in place at the transition between the door leaf and the frame.
Fig. 4 shows such a forward feeding key 9 which has a U-shaped notch at the short side which receives the fractural impression of the locking cylinder. At forward feeding the forward feeding key is pulled out of the fractural impression, the locking cylinder is pushed forward one fractural impression and the broken off locking cylinder piece is forced out and may be removed. Then the forward feeding key is reinserted into the fractural impression and an unbroken fractural impression is held in a correct position.
Fig. 5 shows in greater detail part of the training door with a seven lever lock cylinder. The seven lever lock cylinder frame cylinder holder 13b and the resilient arrangement that allows the seven lever lock cylinder to shear out are illustrated.
Fig. 6 shows in greater detail the long side of the training door that faces the door frame. One end of a locking cylinder is illustrated, as well as a frame cylinder holder 13c and the springs 7b 1-2 that resiliently holds the frame cylinder holder in place.
Fig. 7 shows a rear view of the upper corner of the training door with a band attached to the frame and with a loop at the other end. The band with a loop is intended for attachment to the door leaf and acts as a fling protector 8 which prevents the door from flinging open when the door has been forcibly entered.
