Description

Technical Field of the Invention

The present invention relates to a lock with reduced energy consumption, suitable for use in mailboxes, cargo lockers or similar cabinet doors.

Background Art

In the prior art, mechanically-operated locks are widely used. Mechanical locks may be vulnerable to outside interventions, and in this type of locks, it is also difficult to keep track of whether the lock is opened or closed. In addition, due to the fact that mechanical locks are locked and unlocked only by applying a physical force, it is not possible to use mechanical locks in places where it is difficult for the user to access.
Electronic locks are used to ensure electronic control of the lock and to monitor the sensor status. Electronic locks in the prior art generally contain a number of elements in the lock body so that the locking and unlocking operations can be performed with the power of the electric motor. This causes an increase in the production costs of the locks.
A prior art publication in the technical field of the invention may be referred to as CN109113443 (A1 ), which discloses an electronic lock discloses that the movement is transferred from the electric motor to the hook by means of the gear structures thereon, thereby the lock is locked and unlocked.

Summary of the Invention

An object of the present invention is to provide a hook lock that is easier to lock and unlock by transferring the energy supplied from the electric motor to the hook in an efficient and cost-effective manner.
Another object of the present invention is to provide a hook lock where the information whether it is opened or closed is inferred in a cost-effective manner.
The hook lock which is the subject of the present invention comprises a main body with an opening suitable for engaging a locking tongue when in use; a spring-loaded hook suitable for rotation within said main body, which can be moved into a released position in which the tongue can move in the opening and a locked position in which the tongue is held in the opening; an electric motor in the main body suitable to be instructed by a user; and a triggering mechanism actuated by the electric motor, which moves the hook from the locked position to the released position by transmitting the movement of the electric motor to the hook. Said triggering mechanism comprises a trigger movable inside the main body, which is movable between a supporting position in which it supports the hook to keep it in the locked position when the hook is in the locked position, and a tensioning position in which it is not in contact with the hook; a transmission shaft associated with the electric motor and on which a shaft spring is wound; a transmission box in which the transmission shaft and the shaft spring are guided, which allows the trigger to be arranged between the supporting position and the tensioning position with the movement from the transmission shaft, and which is suitable to be moved by the shaft spring; a shaft protrusion positioned on the transmission shaft and interacting with the shaft spring, which ensures that the shaft spring is wound towards the trigger when the transmission shaft is rotated and that the shaft spring is wound away from the trigger when the transmission shaft is rotated in the other direction. In this way, the rotational movement from the electric motor has been converted into a linear movement within the main body. By rotating the electric motor in both directions, locking and unlocking of the hook lock is electromechanically performed. In this way, the movement of the electric motor is also efficiently transmitted to the hook. The number of parts used in the main body is reduced, thereby reducing the cost of the hook lock.
In a preferred embodiment of the invention, the transmission box comprises a first portion in the form of a hollow box, in which the transmission shaft extends at least partially. The first portion is in the form of a rectangular hollow box. The first portion includes two side walls suitable for pushing the shaft spring thereto. This facilitates the movement of the transmission box by means of the shaft spring. The first portion is made of plastic material.
In a preferred embodiment of the invention, the transmission box comprises a trigger housing located next to the first portion, which is suitable for engaging the trigger therein.
By engaging the trigger in the trigger housing, the transmission box is moved with the trigger.
In a preferred embodiment of the invention, the hook lock comprises a gear set that connects the transmission shaft to the electric motor. In this way, the movement of the electric motor is efficiently transmitted to the transmission shaft.
In a preferred embodiment of the invention, the gear set includes an electric motor gear associated with the electric motor and a secondary gear having a radius greater than that of the electric motor gear, which is associated with the electric motor gear. The secondary gear ensures that the torque obtained from the electric motor is reduced and transferred to the transmission shaft.
In a preferred embodiment of the invention, the gear set includes a transmission gear that is associated with the secondary gear. Since the transmission gear rotates in the same direction as the electric motor gear, it is ensured that the electric motor and the transmission shaft are rotated in the same direction by mounting the transmission shaft on the transmission gear. In addition, by choosing the radius of the transmission gear and the secondary gear differently, the value of the torque to be transmitted to the transmission shaft can be adjusted once again. Thanks to the adjustment of the torque with more than one gear, the size of the gears to be used is reduced.
In a preferred embodiment of the invention, the hook lock comprises a control card that controls the operation of the electric motor by being electrically coupled with the electric motor. The control card regulates the operation of the electric motor. In addition, the information about the opening and closing of the hook lock, and the dates thereof can be recorded in the memory of the control card so that it can be followed by the user.
In a preferred embodiment of the invention, the hook lock comprises a communication module that allows the control card to be instructed by the user. By sending an instruction to the control card via the communication module, the user is able to open or close the hook lock electronically. In a preferred version of the invention, the communication module enables the user to communicate wirelessly with the control card. When the communication module includes one of the wireless communication tools such as WIFI, NFC, Bluetooth, etc., it enables the user to provide instructions to the remote control card through communication with a mobile device.
In a preferred embodiment of the invention, the hook lock comprises a switch which is electrically coupled with the control card, which has a switch arm that can be pressed by the hook, and which has a closed position in which the hook presses the switch arm when it is in the locked position and completes the circuit and an opened position in which the hook does not contact the switch arm when it is in the released position and the circuit is left open. In this way, whether the hook is in the locked position or not can be determined by the control card. In addition, the control card can determine how long the hook remains in the locked position or how long the hook remains in the opened position.
In a preferred embodiment of the invention, the hook lock comprises a trigger spring that is connected to the trigger and applies force to the trigger in the direction of moving the trigger to the supporting position when the trigger is in the tensioning position. In this way, when the transmission box is moved away from the trigger on the transmission shaft, the trigger is moved from the tensioning position to the supporting position by means of the spring force.
In a preferred embodiment of the invention, the hook lock comprises a trigger arm located on the trigger, which extends outward from the main body and which is suitable to be moved by the user. In this way, the hook lock can be opened manually by the user.
In a preferred embodiment of the invention, the hook lock comprises a motor cover located inside the main body, which covers the electric motor and enables the electric motor to be carried in the main body.

Detailed Description of the Invention

Within the scope of the present invention, the hook lock (10) comprises a main body (20) with an opening (21) suitable for engaging a locking tongue (50) when in use; a spring-loaded hook (30) suitable for rotation within said main body (20), which can be moved into a released position in which the tongue (50) can move in the opening (21) and a locked position in which the tongue (50) is held in the opening (21); an electric motor (40) in the main body (20) suitable to be instructed by a user; and a triggering mechanism (60) actuated by the electric motor (40), which moves the hook (30) from the locked position to the released position by transmitting the movement of the electric motor (40) to the hook (30). In Fig. 1, the hook (30) is in the released position and in Fig. 2, the hook (30) is in the locked position. In Fig. 3, the hook (30) is in the locked position, holding the tongue (50) in the opening (21). The hook spring, which is associated with the hook (30), applies a force on the hook (30) in the direction of moving the hook (30) from the locked position to the released position. The electric motor (40) is an electric motor (40) that can rotate in both directions.
Said triggering mechanism (60) comprises a trigger (61) movable inside the main body (20), which is movable between a supporting position in which the triggering mechanism (60) supports the hook (30) to keep it in the locked position when the hook (30) is in the locked position, and a tensioning position in which it is not in contact with the hook (30); a transmission shaft (62) associated with the electric motor (40) and on which a shaft spring (64) is wound; a transmission box (63) in which the transmission shaft (62) and the shaft spring (64) are guided, which allows the trigger (61) to be arranged between the supporting position and the tensioning position with the movement from the transmission shaft (62); at least one shaft protrusion (65) positioned on the transmission shaft (62) and interacting with the shaft spring (64), which ensures that the shaft spring (64) is wound towards the trigger (61) when the transmission shaft (62) is rotated, so that a force is applied to the trigger (61) to move the trigger (61) from the supporting position to the tensioning position by moving the transmission box (63) by means the shaft spring (64), and that the shaft spring (64) is wound away from the trigger (61) when the transmission shaft (62) is rotated in the other direction, thereby enabling the trigger (61) to be moved from the tensioning position to the supporting position by moving the transmission box (63) by means of the shaft spring (64). When the hook (30) is in the locked position and the trigger (61) is in the supporting position, the trigger (61) supports the hook (30) to keep it in the locked position. When the electric motor (40) is started, the movement of the electric motor (30) is transmitted to the transmission shaft (62). The transmission shaft (62) is a shaft rotating with the electric motor (40). The transmission box (63) is disposed on the transmission shaft (62) in a linearly movable manner. The transmission box (63) includes a first portion (631) in the form of a hollow box, in which at least a part of the transmission shaft (62) extends. The shaft spring (64) is wound on the transmission shaft (62) such that at least a part thereof remains inside the transmission box (63). The shaft spring (64) is preferably a spiral spring. A shaft protrusion (65) is provided on the transmission shaft (62), extending from the transmission shaft (62) to the shaft spring (64). The shaft protrusion (65) is in the form of a protrusion on the transmission shaft (62) such that it is within the spring pitch of the shaft spring (64). The shaft protrusion (65) may be a shaft disposed on the transmission shaft (62). As can be seen in Fig. 10, when the transmission shaft (62) is rotated by the electric motor (40) in the winding direction of the shaft spring (64), the shaft protrusion (65) moves the shaft spring (64) to bring it closer to the trigger (61) on the transmission shaft (62). The number of the shaft protrusion (65) can vary, preferably only one shaft protrusion (65) is used in the form of a cylindrical shape. In the case, the transmission box (63) is moved towards the trigger (61) by means of the shaft spring (64) and pushes the trigger (61), causing the trigger (61) to be moved from the supporting position to the tensioning position. In Fig. 11, the transmission box (63) has been moved towards the trigger (61) on the transmission shaft (62) and is in the position where it pushes the trigger (61). The trigger (61) does not contact the hook (30) when it is moved by the transmission box (63) from the supporting position to the tensioning position. As the hook spring applies force on the hook (30) in the direction of moving the hook (30) from the locked position to the released position, the hook (30) takes the released position when the trigger (61) is moved to the tensioning position. In Figs. 7 and 9, the trigger (61) is in the tensioning position where it is pushed by the transmission box (63), and the hook (30) is in the released position where it is not supported by the trigger (61).
When the hook (30) is to be moved from the released position to the locked position, the transmission shaft (62) is first rotated by the electric motor (40) opposite to the winding direction of the shaft spring (64). As can be seen in Fig. 12, when the transmission shaft (62) is rotated opposite to the winding direction of the shaft spring (64), the shaft protrusion (65) moves the shaft spring (64) on the transmission shaft (62) away from the trigger (61). In this case, the shaft spring (64) moves the transmission box (63) on the transmission shaft (62) away from the trigger (61). In Fig. 13, the transmission box (63) is in a position in which it is moved on the transmission shaft (62) such that it is moved away from the trigger (61) by the shaft spring (64). When the transmission box (63) is in this position, the trigger (61) takes the supporting position. In an embodiment of the present invention, the transmission box (63) includes a trigger housing (632) located next to the first portion (631), which is suitable for inserting the trigger (61) therein. The trigger housing (632) is located adjacent to the first portion (631) and is U-shaped. At least a portion of the trigger (61) is inserted in the trigger housing (632). When the trigger (61) is inserted in the trigger housing (632), the trigger housing (632) engages the trigger (61). In this way, the transmission box (63) and the trigger (61) are associated with each other to move together. In this case, when the transmission box (63) is moved towards the trigger (61), the trigger (61) moves with the transmission box (63) and is moved to the tensioning position. When the transmission box (63) is moved away from the trigger (61), the trigger (61) is pulled by the transmission box (63) and moved to the supporting position to support the hook (30).
In another embodiment of the invention, the trigger (61) is supported by a trigger spring (66) to move the trigger (61) from the tensioning position to the supporting position. In this case, when the transmission box (63) is moved towards the trigger (61) on the transmission shaft (62), a force is applied to the trigger (61) by the transmission box (63) which is greater than that applied by the trigger spring (66) and the trigger (61) is moved from the supporting position to the tensioning position. When the transmission box (63) is moved on the transmission shaft (62) away from the trigger (61), the force applied by the transmission box (63) on the trigger (61) is eliminated and the trigger (61) is moved to the supporting position with the force applied by the trigger spring (67). When the trigger (61) is moved to the supporting position, the hook (30) is manually rotated by the user and moved to the locked position. In Figs. 6 and 8, the trigger (61) is in the supporting position and the hook (30) is in the locked position.
In an embodiment of the invention, the hook lock (10) comprises a gear set (90) that enables the transmission shaft (62) to be associated with the electric motor (40). Said gear set (90) comprises an electric motor gear (91) associated with the electric motor (40), and a secondary gear (92) associated with the electric motor gear (91), and having a radius greater than that of the electric motor gear (91). The secondary gear (92) is rotated in a different direction than the electric motor gear (91). Since the radius of the secondary gear (92) is greater than that of the electric motor gear (91), the number of revolutions is less than that of the electric motor gear (91). In a preferred version of the invention, the radius of the secondary gear (92) is 2 times the radius of the electric motor gear (91). In another embodiment of the present invention, the hook lock (10) comprises a transmission gear (93) which is associated with the secondary gear (92). The transmission gear (93) rotates in the same direction as the electric motor gear (91) and in a different direction than the secondary gear (92). The radius of the transmission gear (93) and the radius of the secondary gear (92) can be different from each other. In this way, the rotational speed of the electric motor (40) is reduced to the required number of revolutions and increased, and transmitted to the transmission shaft (62). In the preferred version of the invention, the transmission shaft (62) is associated with the transmission gear (93).
In an embodiment of the invention, the hook lock (10) comprises a control card (70) that controls the operation of the electric motor (40) by being electrically coupled with the electric motor (40). The control card (70) can determine the rotational direction of the electric motor (40) by sending a signal to the electric motor (40). The control card (70) is also a processor into which software can be loaded. In this way, the starting time and/or operation period of the electric motor (40) can be adjusted.
In an embodiment of the invention, the hook lock (10) comprises a communication module that allows the control card (70) to be instructed by the user. The communication module can be located on the main body (20) in electrical connection with the control card (70). The communication module can be a mechanical button or a user interface with a screen. The user can provide instructions to the control card (70) to start and/or stop the electric motor (40) via the communication module. In addition, the user can upload software on the control card (70) via the communication module, by which he can preset the starting and stopping times of the electric motor (40). For example, when the user uploads an algorithm on the control card (70) for relocking the hook lock (10) in 10 seconds after it is opened, the hook lock (10) can be unlocked and locked without requiring a second locking instruction by the user.
In a possible embodiment of the invention, the hook lock (10) comprises a switch (80) which is electrically coupled with the control card (70), which has a switch arm (81) that can be pressed by the hook (30), and which has a closed position in which the hook (30) presses the switch arm (81) when it is in the locked position and completes the circuit, and an opened position in which the hook (30) does not contact the switch arm (81) when it is in the released position and the circuit is left open. When the hook (30) is in the locked position, it pushes the switch arm (81) and moves the switch (80) to the closed position. When the switch (80) is in the closed position, it is determined by the control card (70) that the hook (30) is in the locked position. When the switch (80) is in the opened position, it is determined by the control card (70) that the hook (30) is in the released position.
In an embodiment of the present invention, the hook lock (10) comprises a sitting surface (68) on the trigger (61) on which the hook (30) sits when the hook (30) is in the locked position and the trigger (61) is in the supporting position. The sitting surface (68) is formed on the trigger (61) in the form of a recess.
In an embodiment of the invention, the trigger (61) comprises a trigger arm (67) of the trigger (61), which extends outward from the main body (20) and is suitable to be moved by the user. The trigger arm (67) extends outward from a main body opening formed on the main body. The main body opening is wide enough to allow the trigger arm (67) to be moved therein. The trigger arm (67) allows the user to manually move the trigger (61) between the supporting position and the tensioning position. In this way, if the electric motor (40) or the control card (70) is damaged for any reason, the hook lock (10) can be opened manually. In addition, if the hook lock (10) is used on a cabinet, it allows the user to open the hook lock (10) from inside the cabinet.
As can be seen in Figure 5, it comprises a motor cover (41) located inside the main body (20), which covers the electric motor (40) and enables the electric motor (40) to be carried in the main body (20). The motor cover (41) also covers the gear set (90) and the transmission box (63), preventing them from being damaged from external impacts.
As can be seen in Figures 1-4, the hook lock (10) comprises a cover (22) that almost completely covers one side of the main body (20). The cover (22) is disposed on the main body (20) in order to prevent the elements inside the main body (20) from being damaged against external impacts. The hook lock (10) comprises a cover protective member (23) located on the cover (22). The cover protective member (23) is made from a metal material. In this way, the durability of the cover (22) is increased.
In an embodiment of the invention, said hook lock (10) can be used on a cabinet or locker.
