Description

LOCKING DEVICE FOR DOOR

The present invention relates to a door lock device, and more particularly, to a door lock device that can safely protect the object that needs to be protected, such as safes and automated teller machines.

In general, a safe is used for storing cash, securities, jewelery, valuable documents, etc., and is widely used for preventing a third party from intruding in addition to a formal user.

However, as the technology related to the safe evolves, the technology for unlawfully opening the safe is continuously improved, so that a safe which is more secure and less likely to be stolen is required. Especially, since the automated teller machine which holds a large amount of cash such as cash dispenser is used in public places, the necessity of security for the safe is emphasized.

The primary purpose of a safe is to prevent a third party from opening the safe no matter what device and method is used. The secondary purpose is to allow the police or private security agency to take the appropriate action It would be to delay opening until it can. At this point, it is almost impossible to open the safe at all when cutting tools and welding devices are developed. It is the most practical way to delay the opening time of the safe as much as possible.

For reference, under the US Underwriters Laboratory (UL) certification, it is stipulated that a safety expert should not be able to open the safe for about 30 minutes in order to be in safety level 1. In other words, it is a top priority to safeguard the safe for the maximum amount of time for devices that are difficult to transport the entire machine, such as cash dispensers.

The present invention provides a locking device for a door that can safely protect an object requiring protection such as a safe and a financial automation device.

In particular, the present invention provides a door locking device that can stably maintain the locked state of the door even when a forced attack is applied to the upper and lower surfaces of the door.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the locking device of the door for opening and closing the storage space of the object, the first locking member provided in the interior of the door and selectively restrains the door to the object And a second locking member provided inside the door and selectively restraining the door to the object, and a rotatable cam provided to be rotatable inside the door and having a first locking constraining part and a second locking constraining part symmetrically with respect to the center of rotation. A member, a first interlocking portion interlocking with the first locking member and optionally restrained by the first locking constraining part, and a second interlocking portion interlocking with the second locking member and optionally restraining on the second locking constraining part, and At the position where the first locking member and the second locking member restrain the door, the rotary cam member supports the first interlocking portion and the second interlocking portion in series.

In the present invention, since the first interlocking portion and the second interlocking portion interlocked with the first locking member and the second locking member can be supported in series by the rotary cam member, for example, the first locking member or the second locking member. When an external force is applied to one of the shocks, the impact may be canceled by the reaction force generated in the other.

The first interlocking portion and the second interlocking portion may be integrally formed or mechanically linked to the corresponding first locking member and the second locking member. For example, the first interlocking portion and the second interlocking portion may be integrally formed with the first locking member and the second locking member in a form of a protrusion. In some cases, the first and second interlocking parts may include one or a plurality of interlocking members that can be mechanically interlocked with the corresponding locking members. For example, the interlocking member may be connected to the corresponding locking member in a conventional link connection manner and interlocked by the locking member.

In addition, the first interlocking portion and the second interlocking portion may be provided in the same structure (or symmetrical structure) with respect to the rotating cam member, but in some cases, the first interlocking portion and the second interlocking portion have different structures (or asymmetry). Structure).

The first locking member and the second locking member can be configured to move in various ways depending on the required conditions and design specifications. For example, the first locking member and the second locking member may be configured to linearly move inside the door and selectively restrain the object. In some cases, the first locking member and the second locking member may be configured to rotate and selectively restrain the object.

The linear movement direction of the first locking member and the second locking member can be changed in various ways according to the required conditions and design specifications. For example, the first locking member may be disposed above the rotary cam member to be provided to be linearly movable along the vertical direction, and the second locking member may be disposed below the rotary cam member to form a straight line with the first locking member. It may be provided to be linearly movable along the vertical direction. In some cases, the first locking member and the second locking member may be disposed along a different line on a non-coaxial basis, or may be disposed along a different line on an inclined line. Alternatively, the first locking member and the second locking member may be configured to linearly move along the horizontal direction or other inclined direction of the door.

The structures of the first locking member and the second locking member can be variously changed according to the required conditions and design specifications. For example, the first locking member may be connected to the first linear link unit and linearly moved by the sliding movement of the sliding member, and connected to the first linear link unit to linearly move together with the first linear link unit, and selectively open the door. It may include a first locking pin portion for restraining the safe. In addition, the second locking member is connected to the second linear link portion that is interlocked and linearly moved by the sliding movement of the sliding member, and is connected to the second linear link portion and moves linearly with the second linear link portion, and selectively locks the door. It may include a second locking pin portion to restrain to.

The structure and shape of the rotary cam member may be variously changed depending on the required conditions and design specifications. For example, the first locking member and the second locking member may be configured to linearly move as the first interlocking part and the second interlocking part move along the circumferential surface of the rotary cam member. More specifically, the circumferential surface of the rotary cam member may be formed with a locking release portion having a height difference with the first and second locking restraints along the radial direction of the rotary cam member, the first corresponding to the rotation of the rotary cam member When the interlocking part and the second interlocking part are located in the corresponding first and second locking restraints, the door may be restrained by the first locking member and the second locking member, and the first interlocking part and the second interlocking part are unlocked. If positioned in the restraint by the first locking member and the second locking member can be released.

In addition, the first and second locking restraints may include first and second protrusion receiving grooves, and the first interlocking portion and the second interlocking portion are accommodated in the first and second protrusion receiving grooves. Movement of the first linking unit and the second linking unit may be temporarily restricted.

In addition, a sliding member may be provided on the inner surface of the door to be slidable. A guide slot may be formed in the sliding member, and the first and second linking units may be configured to linearly move as the first and second linking units move along the guide slots when the sliding member is slid. In some cases, it is possible to exclude the separate sliding member and simply configure the locking member to be interlocked and linearly moved by the rotary cam member.

In addition, a locking groove may be formed in the first locking member and the second locking member, and may include a locking protrusion connected to the sliding member to slide together with the sliding member and selectively restrained by the locking groove. In the position where the locking member and the second locking member restrain the door, the locking protrusion may be accommodated in the locking groove and restrain the linear movement of the locking member. In addition, the guide slot may be formed in a curved shape so that the locking protrusion may be constrained to the locking groove or naturally separated from the locking groove in response to the sliding movement of the sliding member.

In addition, a locking unit which is interlocked by the rotation of the rotary cam member and moves linearly in a direction intersecting with the first locking member and the second locking member may be provided. For example, the locking unit may be configured to be interlocked by the rotation of the rotating cam member and linearly move in a direction (left and right directions) perpendicular to the first locking member and the second locking member. For reference, in the present invention, the locking part is a concept including both a restraining element that directly restrains the door and the safe, or an interlocking element that is provided to be interlocked (or linked) with the restraining element to indirectly restrain the door to the object. Can be understood. For example, the locking part may include a side locking pin part that linearly moves and selectively protrudes to the side of the door by interlocking by the rotation of the above-described sliding member and the rotary cam member.

According to the lock device for a door according to the present invention, it is possible to safely protect an object requiring protection such as a safe and a financial automation device.

In particular, according to the present invention, even if a forced attack is applied to the upper and lower surfaces of the door, the locked state of the door can be stably maintained. That is, according to the present invention, the first interlocking portion and the second interlocking portion interlocking with the first locking member and the second locking member are disposed on the rotating cam member while the first and second locking members are disposed at the positions restraining the door. Since it can be supported in series by, the impact can be canceled by the reaction force generated in the other when the external force is applied to the first locking member or the second locking member. Therefore, even if a forced shock is applied to the first and second locking members, the locked state of the door by the locking member can be more stably maintained, and the time for opening the safe by the intruder can be delayed as much as possible.

Further, according to the present invention, in a state in which the first and second locking members are disposed at the position restraining the door, the locking protrusion is constrained to the locking groove and thereby restrains the linear movement of the locking member, thereby forcing the locking member to be forced. Even if the impact is applied, the locked state of the door by the locking member can be more stably maintained.

Further, according to the present invention, since the locking member can be restrained by the locking protrusion and the locking groove, the shock transmitted to the sliding member through the locking member can be minimized, and the abnormal slide movement of the sliding member due to the impact can be prevented. Can be.

For example, the safety plate may be provided between the inner surface of the door 110 and the base plate 112, and may be configured to be destroyed when a predetermined or more forced impact is applied from the outside. Hereinafter, the safety plate will be described with an example formed of a glass material that can be destroyed by a predetermined or more impact. In some cases, the safety plate may be formed of other materials that can be destroyed by a certain amount of impact, and the present invention is not limited or limited by the material and characteristics of the safety plate.

In addition, an auxiliary locking part (not shown) may be provided inside the door 110 to restrain the door 110 to the safe 100 when the safety plate is destroyed by a predetermined or more forced impact from the outside. . For example, the auxiliary locking unit may be configured to hold the door 110 in a locked state by restricting the sliding movement of the sliding member 220 when a forced impact greater than a predetermined level is sensed from the outside.

Hereinafter, the locking rod (not shown) provided on the inner surface of the door 110 to be linearly moved to the restraining position to allow the sliding movement of the sliding member 220 and the release position to allow, the one end is the safety For example, a connecting member (not shown) connected to the plate and the other end connected to the locking rod and a locking spring (not shown) for providing an elastic force to move the locking rod to the restraint position will be described. In addition, a constraining hole 226 may be formed at a side end of the sliding member 220, and the locking rod may be constrained to the constraining hole 226 in a state where the locking rod is disposed at the constraining position.

The locking rod is provided on the base plate 112 so as to be linearly movable to a restraining position and a releasing position allowing restraining the slide movement of the sliding member 220. The locking rod disposed at the releasing position is connected by a connecting member. It can be supported and maintained in an arrangement state, and the locking rod can be moved to the restrained position by the elastic force of the locking spring when the safety plate is destroyed by a forced shock from the outside.

For example, the locking rods may be provided in pairs spaced apart from each other at predetermined intervals, and each locking rod may be connected to the safety plate by a connecting member. The locking springs provide an elastic force to move the respective locking rods to the restraint position, but the locking rods can be maintained in the unlocked position by the connecting member until the safety plate is broken. However, when the safety plate is destroyed, the locking state (restricted to be placed at the release position) of each locking rod is released and at the same time, each locking rod is moved to the restraining position by the elastic force of the locking spring, so that the sliding member 220 Constrain slide movement.

In addition, a protective cover member (not shown) is provided on an inner surface of the door 110 to protect various components such as the sliding member 220, the first and second locking members 230 and 230 ′, the locking assembly 240, and the like. May be provided. Preferably, the protective cover member may be provided in a size and structure that can effectively protect the components mounted on the base plate 112.

In addition, a sensing wire (not shown) may be provided in the interior of the door 110 so as to be broken in response to a forced intrusion from the outside, and an emergency locking unit for restraining the door to the safe when the sensing wire is broken ( Not shown) may be provided. For example, the emergency locking part restrains the first locking member 230 and the second locking member 230 'when the sensing wire is disconnected due to forced intrusion from the outside, so that the door 110 is restrained by the safe 100. It may be configured to. It is also possible to arrange the emergency locking portion to restrain the sliding member or the locking assembly so that the door is locked to the safe when the sensing wire is broken.

On the other hand, as a method for opening an object such as the safe 100 described above, a method of destroying the first locking member 230 and the second locking member 230 'through the upper and lower attacks of the safe 100 may be expected. have. That is, as shown in Figure 3, after drilling the upper (or bottom) outer wall of the safe 100, by using a hammer to directly attack the end of the first locking member 230 and the second locking member 230 ' A method of destroying the first locking member 230 and the second locking member 230 'may be expected. In particular, in the structure in which the guide slot is inclined so that the first and second locking members can be interlocked by the sliding member, the impact applied to the first and second locking members is transmitted to the sliding member along the inclination of the guide slot and slides. There is a problem that the member may be pushed out, thereby restraining the restraint by the first and second locking members.

However, in the state where the first locking member 230 and the second locking member 230 'are arranged to restrain the door as in the present invention, the first locking member 230 and the second locking member 230' are respectively. In a structure in which the first interlocking portion 236 and the second interlocking portion 236 'may be supported in series by the rotary cam member 250, the first locking member 230 and the second locking member 230 are interlocked. Even if a forced shock is applied to '), the restrained state by the first locking member 230 and the second locking member 230' can be relatively stable. That is, since the first locking member 230 and the second locking member 230 ′ which are disposed symmetrically up and down may be supported in series by the rotary cam member 250, the first locking member 230 and the second locking member 230 may be supported. When an external force F is applied to one of the locking members 230 ′, an impact may be canceled by the reaction force F ′ generated at the other, and the first locking member 230 and the second locking member ( 230 ') damage can be suppressed as much as possible. Therefore, the intruder should use another dismantling operation to release the locking state by the rotating cam member 250, or use equipment that can apply even greater impact. Therefore, the time required for opening the safe 100 is delayed so much that the intruder can not open the safe 100 in a short time as intended.

Furthermore, since the locking protrusion 224 can be confined to the locking groove 233 in a state where the first and second locking members 230 and 230 'are arranged to restrain the door 110, the first and second locking members Even if an impact is applied to the 230 and 230 ′, the restrained state by the first and second locking members 230 and 230 ′ may be stably maintained.

On the other hand, in the normal opening, as shown in FIG. 4, as the rotating cam member 250 rotates, the first interlocking portion 236 and the second interlocking portion 236 ′ move toward the unlocking portion 254, thereby rotating the cam. The support state by the member 250 may be released. In addition, as the sliding member 220 slides, the locking protrusion 224 may be separated from the locking groove 233, and at the same time, the first locking member 230 and the second locking member 230 ′ are interlocked. The restrained state of the first locking member 230 and the second locking member 230 ′ may be released by linear movement.

On the other hand, Figure 5 is a view for explaining a door locking device according to another embodiment of the present invention. In addition, the same or equivalent portions as those in the above-described configuration are denoted by the same or equivalent reference numerals, and a detailed description thereof will be omitted.

In the above-described and illustrated embodiments of the present invention, an example in which the first locking member and the second locking member are supported by the rotating cam member is described. However, in some cases, the other locking unit may be formed by the rotating cam member. It can be configured to be supported.

That is, referring to FIG. 5, a locking unit which is interlocked by the rotation of the rotating cam member 1250 and linearly moves along a direction crossing the first locking member 1230 and the second locking member 1240 may be provided. . For example, the rotating cam member 1250 may be provided in a substantially cross shape in which the locking constraining portion 1252 and the unlocking portion 1254 having a height difference are alternately formed along the circumferential direction, and the locking portion rotates the cam. It may be interlocked by the rotation of the member 1250 and may be configured to linearly move in a direction (left and right directions) perpendicular to the first locking member 1230 and the second locking member 1240.

For reference, in the present invention, the locking unit is provided to be interlocked with (or associated with) the restraining element that directly restrains the door 110 and the safe 100, or the restraining element to indirectly restrain the door 110 to the object. It can be understood as a concept including all of the interworking elements. For example, the locking part may include a side locking pin part 1260 that linearly moves by interlocking with the rotation of the sliding member 1220 and the rotary cam member 1250 and selectively protrudes toward the side of the door. In addition, the safe box 100 may be formed with a side binding groove (not shown) for accommodating the protruding side locking pin portion 1260. In some cases, other parts may be configured to be interlocked with the rotary cam member 1250, and the present invention is not limited or limited by the type and characteristics of the locking part.

In addition, at least one of the first locking member, the second locking member, and the locking part interlocked by the rotary cam member may be supported by the spring member and configured to elastically move linearly.
