Description

Emergency door opening device {Emergency door opening device}

The present invention relates to an emergency door opening device that allows the door to be quickly and easily forcibly opened when entering a building, etc. in an emergency situation such as terrorism, life-saving, or fire.

In order to quickly suppress the incident when a major criminal incident such as a terrorist attack, hostage incident, or drug incident occurs, suppression forces need to enter the building as quickly as possible. For example, if entry is delayed, evidence such as drugs may be hidden or destroyed, and criminals may be given time to escape from the residence or violently resist the suppression forces with weapons.

Additionally, in various emergency situations, such as when a fire accident occurs, a suicide attempt occurs, or a patient requiring emergency occurs, police officers or firefighters must quickly enter the inside of a normal house or other structure protected by an entrance door.

However, when emergency response personnel such as police officers or firefighters arrive at the scene of an incident, golden time is often missed due to failure to open the door if the door is broken or locked.

There are two types of doors: the push-open method and the pull-open method. In Korea, most people use the pull-open method. However, due to the structural characteristics, it is relatively easy to force open a push door by applying a physical blow, whereas it is quite difficult to force open a pull door even by applying a physical blow.

Earth teams, police stations, and even special forces rarely have the equipment to force open doors. For this reason, in the event of an emergency, it is common to open the door with the help of the fire department. However, even in the case of fire departments, they do not have any special means, so they limit themselves to simply breaking open the door with a hammer, etc.

As a result, entry into the house is delayed, which often results in serious emergency situations such as loss of precious life due to missing the golden time in emergency situations where every minute is urgent, and it is also quite difficult to force open the door. there is.

Therefore, there is an urgent need for the emergence of forced door opening equipment that can force open doors more quickly and easily and can be easily moved and used in emergency situations.

Specific features and other advantages of the present invention and methods for achieving them will become clear by referring to the embodiments described in detail below along with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms. The present embodiments are merely provided to ensure that the disclosure of the present invention is complete and to be understood by those skilled in the art. It is provided to fully inform those who have the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, an emergency door opening device according to embodiments of the present invention will be described with reference to the drawings.

1 to 6, the door emergency opening device 1 according to the present invention can be basically configured to include a main frame unit, a support member 20, a double-acting actuator 30, and a piercing member 40. .

The main frame unit may include a base 10 and a post 11. The base 10 may be configured in the form of, for example, a square table. A plurality of wheels 15 may be appropriately arranged on the lower surface of the base 10 for smooth movement. Accordingly, the main frame unit is movable and is very easy to move.

One side of the base 10 may be provided with a clip holder (16) for mounting the support rod 50, which will be described later.

The post 11 is, for example, configured in the shape of a square tube and may be installed vertically on the upper surface of the base 10. The post 11 may be composed of first and second posts 12 and 13 that are coupled to allow relative movement so that the length (height) can be adjusted.

The lower end of the first post 12 is fixed to the upper surface of the base 10. The second post 13 can be movably inserted into the first post 12. On one side of the second post 13, a plurality of fastening holes 13a for length (height) adjustment may be provided at regular intervals along the length direction. The first and second posts 12 and 13 may be integrally coupled and fixed by bolts 14. Accordingly, it is possible to adjust the length (height) of the post 11 by fastening the bolt 14 to the first post 12 through one of the fastening holes 13a of the second post 13.

The support member 20 may be configured in various shapes. For example, as shown, it may be configured to include two leg portions 21 configured in a U shape. The two leg portions 21 may be arranged to face each other at intervals by means of a plurality of connecting rods 22 . Also, one of the plurality of connecting rods 22 can be connected to the top of the second post 13 and thus be mounted on the main frame unit.

Both ends of each leg portion 21 contact and support the wall surface W around the door D. Accordingly, contact pads 23 can be provided at both ends of the leg portion 21 to enable stable close contact with the wall surface W.

As shown in FIG. 3, the contact pad 23 may have a block-shaped body 24 and a coupling portion 25 extending from one side of the body 24. The coupling portion 25 is configured in a tubular shape into which the end portion of the leg portion 21 can be inserted, and has a fastening hole 25a so that it can be fixed to the leg portion 21 with a bolt 27.

The contact pad 23 may be made of various materials, for example, it may be made of rubber, urethane, or felt. The contact pad 23 adheres to and supports the wall W of the building, and since a very large hydraulic pressure is applied when the door D is forcibly opened, there is a risk that the wall W may be damaged. Additionally, in some cases, the contact pad 23 may support a wall made of glass or metal, so this needs to be fully taken into consideration.

Therefore, the contact pad 23 is preferably made of a material relatively softer than the wall W, and has a coefficient of friction so that slipping can be minimized without causing scratches on the concrete wall W or glass wall. It may be better to have a large piece of rubber, urethane, or felt.

Additionally, it may be desirable for a magnet 26 to be inserted into the body 24 of the contact pad 23. The magnet 26 can more reliably adhere the support member 20 to the wall W when the wall W is made of metal.

The double-acting actuator 30 may be composed of a double-acting hydraulic cylinder that can exert large force. Accordingly, the double-acting actuator 30 is provided with a hydraulic device 33 on the base 10 of the main frame unit, and can receive the necessary hydraulic pressure. The controller 34 for operating the double-acting actuator 30 may be configured as a button or joystick type, and may be attached to the connection bar 22 of the support member 20, for example.

In the double-acting actuator 30, the cylinder body 31 may be mounted on any one connection bar 22a of the support member 20. The double-acting actuator 30 may be simply mounted to be fixed to the support member 20, or may be rotatably mounted on the support member 20 by the rotation means 35, as shown in FIG. 2. Accordingly, the double-acting actuator 30 can appropriately adjust the direction (angle) in which the operating rod 32 acts depending on the usage environment or needs.

The rotation means 35 may include, for example, a first hinge bracket 36 provided on the connection bar 22a of the support member 20 and a second hinge bracket provided on the cylinder body 31 of the double-acting actuator 30. It may be configured to include a hinge bracket 37. The first and second hinge brackets 36 and 37 may be rotatably connected by a hinge pin (38).

The first hinge bracket 36 may be provided with a fixing bolt 39 for fixing the position of the double-acting actuator 30. And the second hinge bracket 37 may be configured in a semicircular shape and may be provided with a plurality of adjustment holes 37a radially along the edge. Accordingly, the installation angle of the double-acting actuator 30 can be adjusted by coupling the fixing bolt 39 of the first hinge bracket 36 to one of the adjustment holes 37a of the second hinge bracket 37.

The piercing member 40 may include a body 41 and two locking wings 43. The body 41 may, for example, be configured to have a circular cross-section and a predetermined length. The body 41 may have an awl 42 formed with a sharp end at one end (tip) so that it can penetrate the door (D) by the double-acting fluid oilator 30.

In addition, two face portions 41a may be provided on the outer surface of the body 41 so that the locking wings 43 can be seated, respectively. The face portions 41a are arranged at 180° intervals to correspond to each other. It is better to form the face portion 41a leaving a certain length from the tip of the body 41, that is, the awl portion 42. Accordingly, a support protrusion 41b is formed at one end (one end toward the awl) of each face portion 41a of the body 41, and these support protrusions 41b are formed on each locking wing 43 as described later. By limiting the unfolding angle when sexually unfolded, the catching wings 43 can be caught on the inner surface of the door (D).

The locking wings 43 may be installed to rest on the two face portions 41a of the body 41. The locking wing 43 can be rotated with respect to the body 41 by having one end (the end toward the awl) supported by the body 41 by the pivot 44. Each locking wing 43 can be biased so that it can be spread relative to the body 41 by a torsion spring (48). The two locking wings 43 can be rotated in opposite directions and spread out on both sides of the body 41.

Meanwhile, the locking wings 43 are restrained to be parallel to the longitudinal direction of the body 41 by the wing restraining member, and the piercing member 40 penetrates the door D by the pushing action of the double-acting actuator 30. After that, the restraints are released and it can unfold elastically.

The wing restraint member may be configured in various forms, for example, as shown, it may be composed of a restraint ring 46 coupled to the outer surface of the body 41 including two locking wings 43. When the piercing member 40 penetrates the door (D), the restraining ring 46 is stopped by contacting the outer surface of the door (D), thereby breaking away from the body 41 and releasing the restraint of the catching wing 43. You can.

This restraining ring 46 may be made of any material such as metal, synthetic resin, or rubber.

The piercing member 40 may be provided with a rod 45 of a predetermined length at the rear end in the longitudinal direction, and a connector 47 may be provided at the distal end of the rod 45 to operate the operating rod 32 of the double-acting actuator 30. ) It can be installed integrally at the tip. The connector 47 and the operating rod 32 of the double-acting fluid oiler 30 may be connected, for example, by a screw connection method.

The support rod 50 is composed of separate parts as shown in the example, and supports the rear end of the double-acting actuator 30 on the wall (W1) opposite the door (D) as shown in Figure 6 when the door (D) is forcibly opened. As shown in 8, it is connected to the rear end of the double-acting actuator 30 and can be used to support the floor when the pushing door (D) is opened.

In addition, although not separately shown, the support rod 50 may be hinged and rotatably connected to the rear end of the double-acting actuator 30. In this case, it is folded and stored in normal times, and only when the door (D) is forcibly opened, it is unfolded and the double-acting actuator (30) is supported on the wall (W1) opposite the door (D) as shown in Figure 6, or the double-acting actuator (30) is supported as shown in Figure 8. (30) can be supported on the floor.

Next, the operation of the door emergency opening device 1 according to the present invention configured as described above will be explained in parallel with FIG. 7.

In order to forcibly open a locked door (D), first, as shown in FIG. 6, the opening device (1) of the present invention is placed in front of the door (D) to be opened, and the operating rod ( 32) The awl portion 42 of the piercing member 40 mounted on the tip is directed toward the door (D). Then, the leg portion 21 of the support member 20 is brought into contact with the wall surface W. Afterwards, secure the main frame unit.

At this time, the main frame unit alone can sufficiently support the operation of the double-acting actuator 30, but preferably the actuator 30 is supported using a support rod 50 to support the double-acting actuator 30 more stably. It is recommended to support the rear end of the door (D) on the wall (W1) opposite.

In this state, the double-acting actuator 30 is operated in the forward direction. Then, as shown in FIG. 7(a), the piercing member 40 touches the door D due to the advancement of the operating rod 32, and as shown in FIG. 7(b), the piercing member 40 touches the door D due to the continued advancement of the operating rod 32 ( D) can penetrate. At this time, the restraining ring 46, which restrains the locking wing 43 to be positioned parallel to the body 41, contacts the outer surface of the door D, preventing passage through the door D.

The forward movement of the operating rod 32 may continue until the entire piercing member 40 as shown in FIG. 7(c) passes completely through the door D. In this way, when the piercing member 40 completely passes through the door (D), the restraining ring 46 is separated from the piercing member 40 by the door (D). Accordingly, the two locking wings 43 can be expanded in opposite directions by the restoring elasticity of the torsion spring 48.

Next, operate the double-acting actuator 30 to operate in the pulling direction. Then, the operating rod 32 retreats, and accordingly, the piercing member 40 retreats outward as shown in FIG. 7(d). When the piercing member 40 retreats, the two locking wings 43 spread on both sides of the body 41 are caught on the inner surface of the door D. At this time, the leg portion 21 of the support member 20 contacts the wall surface W around the door D and supports the double-acting actuator 30 to strongly pull the door D.

Then, when the operating rod 32 retreats further, the door D may be pulled by the locking wing 43 and opened.

Figure 8 schematically shows another embodiment of the door emergency opening device 1 according to the present invention.

This embodiment is configured to forcibly open the push-open door (D). The installation angle of the double-acting actuator 30 is appropriately adjusted by the rotation means 35 so that the operating rod 32 faces upward, and the double-acting actuator 30 is supported on the floor at the rear end of the cylinder body 31. To do this, the support rod 50 may be connected.

In addition, at the tip of the operating rod 32 of the double-acting actuator 30, there is an adhesive pad 60 that pushes the door D by contacting the lower part of the door lock (L) instead of the piercing member 40 described above. A close contact pad 60 may be installed at the bottom of the installed, inclinedly arranged support rod 50 to stably support it on the floor.

The contact pad 60 can be rotated relative to the first and second contact pads 61 and 62 by connecting them with a hinge pin 63. Here, the contact pad 60 mounted on the operating rod 32 of the double-acting actuator 30 functions as a push pad that pushes the door (D), and is mounted on the support rod 50 to support the floor surface. The pad 60 functions as a support pad.

In this embodiment, the push-open door (D) can also be quickly and forcefully opened using the double-acting actuator 30.

Those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
