Description

Technical Field

[0001] The present invention is in the field of forced entry. In particular, the present invention relates to a reusable door and frame assembly for training first responders, law enforcement officers, and military personnel in the use of breaching tools. Background Art

[0002] Many different types of breaching tools are standard equipment for police, firefighters, and military personnel in the performance of their duties to force entry into buildings. In order to maximize the effectiveness of these tools and reduce the time required to force a door open, these personnel must be trained in their use. Doors used as training aids must be extremely strong to resist damage caused by the tremendous forces that breaching tools exert on the door and frame, especially when they are introduced into the space between the door edge and the door jamb.

[0003] US 9,318,028 discloses a door breaking training door assembly. A unique feature of the assembly is rubber mounts at the top and bottom of the vertical door jambs, connecting the door jambs to the top and bottom horizontal subassemblies of the door frame. When a breaching tool is inserted between the edge of the door and the door jambs, these rubber mounts deform, allowing the jambs to move away from the door during the breaching operation. Another feature of the assembly is a replaceable metal sleeve that covers and protects the edge of the door from damage caused by the tool breaching the door.

[0004] US 8,926,332 is a continuation of US 8,408,917 and discloses a training device for forcibly entering a door using a prying tool such as a crowbar. The door frame consists of two vertical members, called door stop jambs and hinge jambs located on both sides of the door. The two jambs are mounted on a base and connected at the top by a horizontal subassembly. The salient features of the device are that the door hinge is mounted on the hinge jamb in a manner that allows sliding movement toward and away from the hinge jamb, and that the hinge includes a spring that deflects the sliding hinge away from the hinge jamb and resists compression with sufficient force to simulate the forces encountered when trying to wedge a prying tool between the door and the door stop jamb.

[0005] The object of the present invention is to provide a robust assembly for training defence and rescue forces to open doors in the most realistic manner, with maximum efficiency and speed.

[0006] Further objects and advantages of the invention will appear as the description proceeds. Summary of the invention

[0073] A training device is shown herein, comprising a door frame and a door connected to the frame by hinges. Three different training components can be mounted on the frame or the door, which are used to train military, police and fire personnel in the skills required to breach a door using different types of breaching tools that can be used to perform manual breaching, mechanical breaching, ballistic breaching, hydraulic breaching and explosive breaching methods. In order to achieve its purpose, the device must, on the one hand, be configured to present the trainee with as many different scenarios as possible that may be encountered in the field, and, on the other hand, must be robust enough to be used repeatedly with minimal damage.

[0074] Figure 1A and 1B The training device 10 is shown on one side and on the opposite side of the device from the operator of the demolition tool. Here, the type of door is defined by the way it is opened in order to enter the fortress, i.e., a house, room, yard, etc. In the door breaking exercise using the training device 10, a door that "opens inwards" is pushed inwards away from the operator of the demolition tool, while a door that "opens outwards" is pulled outwards towards the operator in order to pass through it. The training device 10 can be used for training on both sides, i.e., the push side or the pull side. Figure 1C The training device 10 is shown from the side approached by a trainee when the door 12 is locked in the door frame.

[0075] The training device 10 includes a door frame 12, a door 14, and a "floating" jamb 16 inserted between the door 14 and the door frame 12. The jamb 16 is supported by the door frame 12 but is not directly fixed to the door frame 12. The embodiment of the training device 10 described herein is configured so that it is connected to the door frame 12 by a hinge 20a (see FIG. Figure 1C And note that the door 14 (which may use two, three or more hinges) can only swing in an outward direction away from the door frame 12.

[0076] The training apparatus 10 is stable enough to normally remain upright during all training exercises; however, if located on a non-level floor or ground, supports may be added to stabilize the device 10. One possible implementation of the support structure is for example Figure 1A , Figure 1B As shown. The design of the support structure should minimize interference with the trainee's activities during the sabotage training. Therefore, in this embodiment, the corner of the locking side of the door frame 12 is located on the floor, and the length of the angle iron 18 located on the floor is installed at the bottom corner of the hinge side of the door frame 12 in a direction perpendicular to the plane of the frame 12. Both ends of the angle iron 18 can be installed with leveling screws. In addition, as shown in FIG. Figure 1C and Figure 2C As shown, at least one support 18A may be added, the top end of which is fixed to the hinge side support of the door frame 12, the bottom end of which is fixed to the angle iron 18, and an additional leveling screw 18c may be added to the flange mounted at the bottom of the locking side support of the door frame 12. The angle iron 18 and any added support 18a are mounted to the frame 12 using bolts, which can be removed to reposition the device 10. The operation of the device 10 is not limited by the support structure, and is specifically not limited by the support structure embodiments described herein.

[0077] like Figure 1A , Figure 1B As shown, three optional training components are attached to the door frame 12, the door 14 or the jamb 16. These training components are not necessarily components of all embodiments of the training device 10. Each of them is designed to train the operator for a specific skill, and they can be installed to the device 10 when one or more of these skills are learned. The training components shown are: the door 20, which is installed at the hinge side pillar of the door frame 12; the upturned flange assembly 22, which is connected to the locking side of the door 14; and the zero clearance door assembly 24, which is composed of two components: a box subassembly 24A installed on the locking side of the door, and a jamb subassembly 24b installed on the jamb. These training components will be described in detail below.

[0078] Figure 2A and 2B The door frame 12 is shown from the side of the device from which an operator of the breaking tool approaches and from the opposite side of the device. Figure 2C The door frame 12 is shown from the side where the trainee approaches the device. Figure 2B As shown, the flat steel plate 26 is the locking side of the half door lintel 12d welded to the top of the door frame 12. The plate 26 is used to simulate a regular door frame so that the trainee can insert a demolition tool into the gap between the top guide rail 14d of the door and the plate 26 to practice upward door breaking. At the upper and lower corners where the door lintel 12d and the threshold 12c intersect with the locking side guide rail 12b of the frame 12, components 28 for supporting the top and bottom of the jamb 16 in the door frame 12 can be seen. Figure 2COther features visible in the embodiment are: posts 18a, leveling screws 18c, and flanges 12f added to both ends of the lintel 12d to allow the frame to be attached to a wall or other structure.

[0079] The assembly 28 includes a box 28a which is mounted, such as bolted or welded, to the lintel 12d and the threshold 12c. The box 28a defines a cavity 28b in which the top and bottom ends of the jamb 16 are loosely fitted. The assembly 28 also includes a spring seat 28c connected to the locking side support 12b of the frame 12. The spring seat 28c is used to horizontally support two springs 28d.

[0080] Figure 3A , Figure 3B The door 14 is shown from one side of the device and from the opposite side, respectively, to that accessible to the operator of the breaking tool. Figure 3C The door 14 is shown from the side where the trainee approaches the apparatus. The door 14 is composed of two horizontal hollow steel profiles and two vertical hollow steel profiles that are welded at their corners to form a rectangle. In the figure, the profiles of the door 14 are identified as follows: hinge side rail 14a, locking side rail 14b, bottom rail 14c and top rail 14d. Steel plates 26b are welded to the inside of the locking side of the bottom rail 14c and the top rail 14d to reinforce when breaking into the door. A flat steel plate 36 is welded to the top of the locking side rail 14b to simulate the flange on the locking side edge of a conventional door. Plate 36 is used to train operators to use breaking tools near the top of an outward-opening door. In the middle of the door 14 are two horizontal profiles 30 and a square metal plate 32, which are used to add rigidity and strength to the door for door breaking exercises using mechanical tools, and to provide a structural element to which subassemblies of the zero-clearance door assembly 24 can be attached. In the Figure 3C Additional features seen in the embodiment of FIG. 1 are: hole 110, hinge 12e and door handle 108, which are added for convenience and to simulate the features of a real door.

[0081] like Figure 3A Shown are a plurality of nuts 38 connected to sleeves 40 protruding through the locking side rails 14b of the door 14 (see FIG. Figure 5 ). Holes 110 through which sleeves 40 pass are bored through locking side rails 14b at different heights to simulate multiple locking positions that must be broken to successfully open the door. Holes 110 are located opposite similar holes 110 through jamb 16 (e.g., Figure 4A and Figure 4B The sleeve 40 has a circular passage 48 extending therethrough (see Figure 5 ). A locking bolt or deadlock pin 46 (eg, Fig.9D4. Although the figures show the sleeve 40 in five holes 110 in the locking side rail 14b, in different embodiments, more or fewer holes 110 may be provided, and in different training scenarios, only one or more sleeves and / or only one or more pins 46 inserted through the sleeves may be used. Figure 3B A steel band 42 can be seen welded to the face of the locking side rail 14b facing the jamb 16. The band 42 includes a plurality of hexagonal sockets into which the hexagonal head 44 of the sleeve 40 is inserted, so as to allow the door 14 to close smoothly against the jamb 16 and to prevent damage to the demolition tool caused by the head of the sleeve protruding from the profile. The pin 46 is made of different materials, depending on the difficulty planned for the demolition exercise. Materials used for the pin 46 include wood, aluminum and steel of varying hardness. The sleeve 40 is provided because in exercises using a hard metal pin 46 that does not include the sleeve 40, it was found that the force applied to the pin 46 during the demolition exercise caused damage to the hole 110 through the locking side rail 14b and the jamb 16. In the course of many training sessions, damage occurs and it is known that the locking side rail 14b and / or the jamb 16 must be replaced. The use of a replaceable sleeve 40 eliminates the need for these expensive and time-consuming replacements. Furthermore, since damage caused by the pin 46 being pulled out of the sleeve 40 during the door-breaking operation is limited to the inner side of the sleeve 40 and the head 44 in the locking side guide 14b facing the jamb 16 (or vice versa), the sleeve 40 is designed with a hexagonal head 44. Therefore, when one face of the head 44 is damaged after multiple uses, the nut 38 can be loosened or removed and the sleeve 40 rotated to expose the next face. In this way, the sleeve 40 can be reused multiple times on six different aspects of its head 44 before it must be discarded and replaced with a new sleeve 40.

[0082] like Figure 3B The nails 50 on the locking side rail 14b are shown. They are located opposite to similar nails 50a on the side column 16 (see Figure 4A A piece of metal or wood may be inserted between the nail 50 on the mating door 14 and the nail 50a on the jamb 16 to create a closer contact between the door and the frame and simulate a locking device such as a striker or bolt.

[0083] Figure 4A and 4BThe door jamb 16 is shown on one side of the device and the other side of the device respectively, which is approached from the operator of the breaching tool. The door jamb 16 is an additional support profile located between the locking side support 12b of the frame 12 and the locking side guide 14b of the door 14. The jamb 16 is supported by the door frame 12; however, it is not directly fixed to the door lintel 12d or the threshold 12c. As follows, the top and bottom of the jamb 16 are free to float in the confined space, that is, move sideways or move forward and backward, so as to allow the jamb 16 to be away from the locking side guide 14b of the door 14 during the breaching exercise without causing damage to the jamb 16 or the locking side guide 14b that occurs in the actual breaching action.

[0084] The jamb 16 is composed of a length of a hollow steel square profile 16a. A first side 16a' of the profile 16a faces the locking side rail 14b of the door 14; an opposite side 16a" of the profile 16a faces the locking side pillar 12b of the frame 12; a third side 16a"' of the profile 16 faces the push side of the door; and a fourth side 16a"" is opposite the opposite side 16a"' and the pull side of the door. A narrow flat steel strip 16b is welded to the third side 16a"' of the profile 16a. The steel strip 16b is suspended on the side 16a"' of the profile 16a on the locking side rail 14b of the door and the locking side pillar of the door 14, simulating a flange that covers the gap between the door and the door frame of a real frame door.

[0085] As discussed above, the holes 110 through the sleeve 40 are drilled through the sides 16a' and 16a" of the profile 16a of the jamb 16 at various heights to simulate multiple locking positions that must be broken to successfully open the door. Figure 4A The threaded end of the sleeve 40 is shown connected to the side 16a" of the profile 16a (see Figure 5 ) of the nut 38. Figure 4B A steel band 42 is seen welded to the side 16a' of the profile 16a of the jamb 16. The band 42 comprises a plurality of hexagonal sockets into which the hexagonal heads 44 of the sleeves 40 are inserted, so as to allow the door 14 to close smoothly against the jamb 16. Figure 4A Visible are nails 50a corresponding to the nails on the locking side rail 14b described above.

[0086] At the top and bottom of the profile 16a are protruding tabs 52. As shown, these tabs 52 can be formed by welding an angle iron piece to the top and bottom of the profile 16a, or alternatively formed by machining the ends of the profile so that the side 16a' of the profile 16a is longer than the other three sides of the profile. In other embodiments, short pins protruding from the top and bottom of the profile 16a can replace the tabs 52. In addition, a bracket 54 is attached to the sides 16a'" and 16a"" at the top and bottom of the profile 16a, and the bracket 54 includes an attached right-angle profile so that one surface of the bracket 54 is located in a plane parallel to the side 16a'" of the profile 16a.

[0087] The clips 52 at the top and bottom of the profile 16a of the jamb 16 mate with the cavities 28b in the boxes 28a of the top and bottom components 28 of the door frame 12. The cavities 28b are large enough to allow the clips 52 to move forward, backward, and laterally therein relative to the frame 12, and the cavities 28b are still supported by the frame 12 when a tool is used to force the door 14 and the jamb 16 apart. Allowing the jamb 16 to move in the cavities 28b protects the jamb 16 from being permanently bent while simulating a scenario of a real door where the door jamb 16 would become distorted during the cracking process.

[0088] The spring 28d of the assembly 28 bears against the bracket 54 on the profile 16a so as to push the side 16a' of the profile 16a of the jamb 16 toward the locking side rail 14b of the door. By pressing the top and bottom of the jamb 16, the spring 28d maintains the locking side rail 14b of the door and the counterpressure of the breaking tool, thereby increasing the difficulty level of inserting the tool into the gap between the jamb 16 and the locking side rail 14b. In order to produce different degrees of difficulty, the spring 28d can be replaced with a spring with different resistance to the compression force trying to move the jamb 16 in the cavity 28b. Another function of the spring 28d is to return the jamb 16 against the door 14 if the tool slips out of the gap, which is a common problem in the door breaking behavior that the trainee must learn to overcome. The hole 56 in the bracket 54 accommodates a bolt or pin inserted into the center of the spring 28d to stabilize its contact with the jamb 16 and prevent any possible slippage of the spring 28d that compresses the bracket 54 during the door breaking process.

[0089] Figure 5 The sleeve 40 described above is shown. The sleeve 40 is sized to be inserted into a hole 110 bored through the jamb 16 of the door frame 12 and the locking side rail 14b of the door 14. The sleeve 40 is a cylindrical sheet of metal having a head 44 at one end having a diameter greater than the hole 110 in the door and jamb and being threaded at the other end. A circular passage 48 (such as a threaded end) into which a pin 46 is inserted Fig.9D4 (shown) through the center of the sleeve 40. The sleeve 40 is slid through the hole until the head 44 abuts against the side of the jamb 16 facing the locking side rail 14b (or vice versa), and the nut 38 is screwed into the threaded end of the sleeve 40 to securely hold it in place.

[0090] Figure 6 It shows that Figure 1A , Figure 1B The gate 20 is an optional feature of the training device 10. The gate 20 is a training component for training personnel to use various demolition tools. The gate 20 is connected to the hinge side support 12a of the door frame 12 by a hinge 20a (such as Figure 1B 1 and 1 ). The gate 20 is made of three vertical lengths 21a-21c and two horizontal lengths 21d and 21e of steel profiles welded together to have a square or rectangular shape. A third horizontal length 21f is welded between the vertical lengths 21a and 21b. A plurality of holes 20b in the horizontal profile allow for the insertion of replaceable rods or bars of metal or wood of different types, strengths and cross-sectional sizes to allow for training with cutting tools (e.g., manual or hydraulic bolt cutters). Chain and chain link fences may also be hung on the gate 20 for training with cutting tools. The flange 20c on the support profile opposite the hinge 20a may be configured to be locked to the door 14 by a padlock.

[0091] A wooden board 112 is inserted into the gate 20 between the vertical profiles 21b and 21c and is held in place by brackets 116. The purpose of the wooden board 112 is to allow ballistic breaching training using, for example, a shotgun.

[0092] For other exercises, the metal plate 32 is bolted to the horizontal profile 30 and allows mechanical breaching training using breaching tools such as sledge hammers, pry bars or battering hammers. Since the metal plate 32 is bolted to the horizontal profile 30 rather than welded, it can be replaced with a new metal plate if it bends or becomes damaged beyond functional limits during training. In order to minimize bending of the metal plate 32 caused by repeated breaching using a casing hammer or a projectile, a covering of conveyor belt material or similar material is bolted to the side of the metal plate facing the trainee. This reduces the frequency of replacing the plate.

[0093] In addition, explosive door breaching training can be conducted using a small charge attached to a bare metal plate 32 or the locking side rail 14b of the door. Dynamic loads that push metal rather than cut metal are used in these training courses.

[0094] A vertical steel U-shaped profile 114 is added to the gate 20 for use with the wooden board 112. A plurality of plates 114a and trailer hitches 114b are attached to the rod 114 to simulate a cylinder lock and a door handle, respectively. This is used to teach the trainee the correct position to aim the shotgun in order to attack most effectively. Holes 114c are drilled horizontally on both sides of the vertical profile 114 directly behind the plates 114a and trailer hitches 114b. Wooden dowels (not shown) can be inserted through the holes 114c extending a few inches on both sides of the vertical steel profile 114. These wooden dowels simulate the latch of the cylinder lock or the bolt of the dead bolt behind the plates 114a and trailer hitches 114b, respectively. When the trainee correctly aims the shotgun and shoots the wooden board 112, the bullet penetrates the wooden board 112 and breaks the wooden board. If the trainee does not aim the shotgun correctly, the wooden clip will remain intact, giving immediate feedback on the trainee's technique and accuracy.

[0095] Figure 1A and 1B Two additional training components are shown that may be added or removed from the device as required by the training course. The flip-up flange assembly 22 is used for training the use of a breaching tool to breach a conventional door having a flange that covers the gap between the door and the jamb. The zero clearance door assembly 24 is used for training the use of a breaching tool to breach a zero clearance door, i.e., a door that is adjacent to a frame and is locked to the frame by a conventional key-activated locking bolt. Both of these components are used to train individuals to breach different types of doors using different types of power, i.e., hydraulic, pneumatic, electrical, or manual, such as slides, sledge hammers, and pry bars, breaching tools. Below, after a description of each of these components, the process of breaching training device 10 will be described using a hydraulic door breaching tool manufactured by the applicant of the present application, as shown in FIG. Fig. 7A , Figure 7B shown.

[0096] Fig. 7A and Figure 7B is a photograph showing two views of a hydraulic door breaching tool 58. The tool 58 includes a connector 60 for connecting to a manual or battery-powered hydraulic pump, a piston cylinder 62, a handle 64, a static tooth assembly / base 66, and a Figure 7B The three wedge-shaped teeth that can be seen most in the figure. Among them, two teeth 70 are fixed on the base 66. When the hydraulic pump is activated, the dynamic middle tooth 68 is pushed forward from the base 66.

[0097] Fig. 8A and Figure 8BThe flip-up flange assembly 22 is shown bolted to the locking side track 14b of the door with a bracket 72a. The assembly 22 includes a rear wall 72 and a bottom wall 74 welded to the bracket 72a, and a front wall 76 connected to the bottom wall 74 by a piano hinge 78. A replaceable sheet metal 80 having a cross-section of a right angle shape is bolted to the side of the front wall 76 facing the jamb 16. The portion 80a of the sheet metal 80 perpendicular to the front wall 76 simulates the protruding edge of a real door. The piano hinge 78 allows the front wall 76 and the sheet metal connected thereto to swing forward and backward relative to the rear wall 72 and the spring 84 in the spring housing 82. When the door 14 of the training device 10 is closed, the spring 84 pushes the portion 80a of the sheet metal 80 downward toward the top of the portion 16b of the jamb 16. The spring 84 can be easily replaced to provide springs with different resistance to compression, thereby providing different degrees of difficulty during training.

[0098] Figure 8C An embodiment of an upturned flange assembly 22' is shown, which is constructed on a U-shaped profile 118. The profile 118 is mounted above and bolted to the locking side rail 14b of the door 14 by bolts 118a. The assembly 22' is substantially the same as the upturned flange assembly 22, and its function is the same with modifications made for the durability of the assembly. Figure 8C Shown are the rear wall 72 and the front wall 76. In this embodiment, the top side of the profile 118 serves as a bottom wall to which the rear wall 76 and other subassemblies including the side walls 122 are welded.

[0099] The flip-up flange assembly 22' consists essentially of two parts: a rear portion fixed to the door by means of the profile 118, and a front portion pivoted relative to the rear portion and flipped from the door jamb 16 during the door breaching operation.

[0100] The rear portion of the upturned flange assembly 22' includes a rear wall 72 and a spring housing 82 fixed to the rear wall 72. A spring 84 pressing against the front wall 76 is shown in the spring housing 82. Figure 8C Shown is a bracket 124 for supporting and mounting a safety cover (not shown).

[0101] Fig.8D and Fig. 8EThe rear view and the front view of the front part of the flip-up flange assembly 22' are shown respectively. The front part includes a front wall 76 and a replaceable sheet metal 80 having a right-angle cross section 80a. In this embodiment, the replaceable sheet metal 80 is sandwiched between the front side of the front wall 76 and the metal plate 126. The metal plate 126 and the sheet metal 80 are fixed to the front wall 76 by bolts 128. The purpose of the metal plate 126 is to increase the strength of the metal plate 80 and reduce the frequency of replacement. It can also be seen in these figures that the vertical portion 80a of the replaceable sheet metal 80 having a right-angle cross section, the right-angle cross section is bolted to the side of the front wall 76 facing the side column 16. A hinge support 130 is welded to the rear side front wall 76. The cover 120 is welded to the top edge of the front wall 76 and the top of the hinge support 130 to stabilize the hinge support 130.

[0102] In the upturned flange assembly 22', the hinge connecting the two parts of the assembly and allowing the front part to pivot relative to the rear part includes a hollow cylindrical rod 134 (see Figure 8C ), which passes through a hole in the side wall 122 mounted on the bracket 118 and a hole 132 near the bottom of each hinge support 130. Grease fittings 132 at the end of the rod 134 allow the interior thereof to be filled with grease, and small holes in the rod wall at the location of each hole in the side wall 122 of the rod and the hole 132 allow grease to leak from the interior of the rod 134 and reduce friction as the front of the flip flange assembly 22' rotates around the rod 134.

[0103] like Fig. 8A and Figure 8B In the upturned flange assembly 22 shown in the figure, the portion 80a of the sheet metal 80 perpendicular to the front wall 76 simulates the protruding edge of a real door. The hinge allows the front wall 76 and the sheet metal 80 connected thereto to swing forward and backward relative to the rear wall 72 and the spring 84. When the door 14 of the training device 10 is closed, the spring 84 pushes the portion 80a of the sheet metal 80 downward toward the top of the portion 16a"" of the side column 16. The spring 84 can be easily replaced to provide springs with different resistance to compression, thereby providing different degrees of difficulty during training.

[0104] 9A to 9D are screen shots showing different stages of a door breaching process performed using the door breaching tool 58 on the training device 10 including the flip-up flange assembly 20 .

[0105] Fig. 9A This is the first stage of the destruction process. The door 14 is closed against the jamb 16, and the spring 84 pushes the front wall 76 of the assembly 20 so that the metal plate portion 80a is suspended on the jamb 16 and abuts against the side 16a"" of the jamb 16. Fig. 9A1 shows the nut 38 on the sleeve 40 through the locking side post 14b on the door 14 and the head 40 of the sleeve through the profile 16a of the jamb 16, indicating the location of the insertion of the pin to simulate at least one dead bolt between the door 14 and the jamb 16. In this step, the dynamic teeth 68 are retracted into the base 66 of the tool 58, and, while the door breaking tool 58 is held perpendicular to the plane of the door 14, the trainee applies the edges of the two static teeth 70 and the dynamic teeth 68 at the base 66 of the tool 58 between the bottom of the sheet metal portion 80a and the top of the steel strip 16b of the jamb 16.

[0106] Fig. 9B The first stage is shown completed. At this stage, the static teeth 70 and dynamic teeth 68 of the hydraulic door breaching tool 58 are fully inserted between the top of the jamb 16 and the bottom of the portion 80a of the sheet metal 80. To allow this and accommodate the thickness of the teeth, the front wall 76 of the assembly 22 and the attached sheet metal 80 pivots around the hinge 78 to compress the spring 84.

[0107] Fig. 9C 58 is shown as it is activated, causing the dynamic teeth 68 to be pushed away from the base 66 of the tool 58. When the tool 58 is activated, two actions occur simultaneously. First, the dynamic teeth 64 apply an inward force to the door jamb 16, allowing the locking side rails 12b to move inwardly relative to the door frame 12 by moving the catches 52 in the cavities 28b at the top and bottom of the jamb 16 (see FIG. 5 ). Figure 2A , 2B , 4A and 4B). The static teeth 70 of the tool 58 then apply an external force to the sheet metal portion 80a, causing it to flip, i.e., the force applied by the tool 58 overcomes the force applied by the spring 84, forcing the front wall 76 of the assembly 22 to move rearward, lifting the sheet metal portion 80a from the jamb 16. The combination of these two actions causes the door 12 to begin to swing away from the frame 14, while applying a tensile force to the pin acting as a dead bolt.

[0108] It should be noted that the design of components 22 and 22' simulates a real door in several ways, including: 1) the pivot mechanism simulates the movement of a fragile door with a weak flange that will bend when hydraulic pressure is applied to the door swinging outward; 2) the pivot mechanism will cause the tool to slip if the trainee does not use correct technique; 3) when the tool slips, the door resets to zero, simulating a real door that will close when the tool slips.

[0109] Fig.9D The door 14 is successfully broken at the stage when the movable tooth 68 is fully extended from the base 66 of the door breaking tool 58. It should be noted that how the telescopic force bends the pin 46, which simulates the dead bolt and pulls it out of the head 44 of the sleeve 22 in the jamb 16.

[0110] A set of holes are provided at different positions on the locking side rail 14 b of the door, which allows the upturned flange assemblies 20 , 22 ′ to be connected at different heights to allow trainees to practice breaking into the door by inserting tools at the top, middle or bottom of the door 14 .

[0111] In actual situations, when a door is breached using a door breaching tool 58 of the type shown in the drawings, the edge of the door is usually damaged beyond repair and the door must be replaced. In addition, the teeth of the tool can easily lose their grip on the door and jamb as the door separates from the jamb. The flexing and bending of the sheet metal 80 simulates both of these phenomena, providing realistic training for the operator of the tool. The use of the upturned flange assembly 22 with the training device 10 allows the sheet metal sheet 80 to be easily, quickly and inexpensively replaced when damaged, allowing the training device 10 to be reused for many additional training sessions.

[0112] Fig. 10A and Fig. 10B The cassette subassembly 24a is shown, and Fig.11A and Fig. 11B The jamb subassembly 24b of the zero clearance door assembly 24 is shown for simulating a zero clearance door, with the locking side rails 14b of the door 14 abutting against the jamb 16 of the door frame 12, and the door 14 being locked to the frame 16 by turning the door bolts with a conventional key.

[0113] The cassette subassembly 24a consists of a frame 86 which can be attached to the locking side rails 14b and the horizontal profile 30 of the door 14 (see FIG. 1 ), if the assembly 24 is not a permanent part of the training device 10 or the assembly is a permanent part by welding. Figure 3A ). Fig. 10A The cassette subassembly 24a is shown from the side facing the trainee / operator, and Fig. 10B Opposite sides are shown. Structural elements 98 serve as guides for slots defining the inner top and inner bottom of the frame 86 in which the box 90 can slide. The box 90 is filled with a replaceable wood insert 92 consisting of one or more wood pieces. A lock body 94 is mounted in the wood insert 92, and a panel 96 is inserted on the edge of the wood insert 92 facing the jamb 16. Turning a key in the lock body 94 causes the lock bolt to extend outward through the panel 96 or retract into the wood insert 92. The subassembly 24a includes a plurality of springs 100 arranged to push the box 90 toward the jamb 16 and provide resistance when the box 90 is forced to slide into the frame 86 and away from the box during the door breaking exercise. Four springs 100 are shown, but in different embodiments, there may be more or less springs. The springs 100 can be easily replaced to provide springs with different resistance to compression, thereby providing different degrees of difficulty during training.

[0114] Subassembly 24b such as Fig.11A and Fig. 11B The subassembly 24b includes a frame 102 configured to be attached to the side 16a'' of the profile 16a of the jamb 16 (see Figure 4A ) and supports a replaceable wood insert 104. Subassembly 24b is connected to the side column 16 by bolts if assembly 24 is not a permanent component of training device 10, or by welding to an embodiment in which assembly 24 is a permanent component. Wood insert 104 is embedded in frame 102 so that one edge of wood insert 104 faces wood insert 92 of subassembly 24a. The edge of wood insert 104 includes a joint plate and a hole (not shown) that receives a locking bolt extending from panel 96 to lock the two subassemblies together.

[0115] Embodiments of the training device 10 are configured with bolt holes to enable the zero clearance door assembly 24 to be mounted on both sides of the door 14. The cassette subassembly 24a and subassembly 24b are secured to the door 14 and the opposite side of the jamb 16 from one side as shown. Figure 1A This shows that door assembly 24 will face the trainee approaching device 10 from the side of door 20. This configuration of training device 10 allows for more complex training exercises in which the trainee must first successfully break through door 20, such as with a shotgun, cutting tool, or hydraulic breaching tool, and then break through door 14, such as with a hydraulic breaching tool.

[0116] Figures 12A to 12D are screen shots showing different stages of a door breaching process performed using the door breaching tool 58 on the training device 10 including the zero clearance door assembly 24 .

[0117] Fig. 12A This is the first stage of the destruction process. The door 14 is locked to the jamb 16 by turning the key on the lock body 94 on the wood insert 92 of the subassembly 24a mounted on the door. Turning the key tightens the locking bolt 106 (see Fig. 12C ) extends from the panel 96 on the wood insert 92 to the striker (not visible in the figure) on the side of the wood piece 104 in the frame 102 of the subassembly 24b mounted on the profile 16b of the profile 16. In this step, the movable teeth 68 are retracted against the base 66 of the tool 58. With the door breaking tool 58 held parallel to the plane of the door, the edges of the three teeth 68 and 70 at the base 66 of the tool 58 are forced between the edge of the wood insert 92 in the subassembly 24a of the box 90 simulating the edge of the door and the wood insert 104 in the subassembly 24b simulating the edge of the jamb 16.

[0118] Fig. 12BThis is the first stage. In this stage, the dynamic teeth 68 and the static teeth 70 of the hydraulic door breaking tool 58 are inserted between the wood plug-in 92 in the box 90 and the wood plug-in 105 in the frame 102 on the side column.

[0119] Note that in assembly 24, the hydraulic door breaching tool 58 is held parallel to the door so that the door is sideways relative to the door frame. This is the opposite of assembly 22 (see Figures 9A-10B ), in assembly 22, a hydraulic door breaching tool 58 is held perpendicular to the door to force the door to swing open away from the door frame.

[0120] exist Fig. 12C In the embodiment, the hydraulic door breaking tool 58 is activated to extend the dynamic teeth 68, which push against the wood insert 104, while the static teeth 70 apply a reaction force to the wood insert 92 in the box 90. The force applied by the dynamic teeth 68 causes the jamb 16 to move laterally from the box 90 in the cavity 28b at the top and bottom of the jamb 16 (see Figure 2A ). At the same time, the force applied by the stationary teeth 70 pushes the box 90 to compress the spring 100. The combination of the movement of the jamb 16 and the compression of the spring 100 causes the box 90 to begin to move away from the profile 16a of the jamb 16 and allows the locking bolt 106 to begin to slide out of the running board on the wood insert 104 in the frame 102 of the subassembly 24b.

[0121] exist Fig.12D , movable tooth 68 has extended to move jamb 16 in one direction, and compression of spring 100 causes box 60 to move in the opposite direction until the distance between subassembly 24a and subassembly 24b is large enough to allow locking bolt 106 to slide completely out of the strike plate and door 14 can be opened from the jamb.

[0122] In real-world scenarios, when hydraulic door breaching tools 58 are employed to open doors, the edges and jambs of the door are often damaged beyond repair and must be replaced. Using the training device 10 with assembly 24, the wood inserts 92 and 104 are easily, quickly, and inexpensively replaced when damaged, allowing the training device 10 to be reused for an unlimited number of additional training sessions while maintaining the exact same breaching techniques used on real doors.

[0123] Although embodiments of the present invention have been described by way of illustration, it will be appreciated that the invention may be susceptible to numerous changes, modifications and adaptations without departing from the scope of the claims.
