The heated lock device 100 of the present invention is not limited to padlocks with keys (as shown in FIGS. 1-5). The device 100 can include combination locks as shown in FIG. 6, FIG. 7, and FIG. 8.
Padlocks
Referring now to FIGS. 1-5, the lock device 100 comprises a housing 110 with a curved lock 115. In some embodiments, the housing 110 and curved lock 115 are generally similar to housings and curved locks 115 of standard padlocks, which are well known to one of ordinary skill in the art. In some embodiments, the housing 110 is larger than standard padlock housings.
As shown in FIG. 1, the first end (first cylinder) of the curved lock 115 is disposed in the inner cavity of the housing 110 and the first end of the curved lock 115 extends out of a first shaft 116 in the top surface 111 of the housing 110. The second end (second cylinder) of the curved lock 115 can move in and out of the inner cavity of the housing 110 via a second shaft 117 disposed in the top surface 110 of the housing 110. Like standard padlocks, a hasp is disposed on the second end of the curved lock 115. A latch in the inner cavity of the housing 110 engages the hasp to lock the lock device 100 and hold the second end of the curved lock 115 in the inner cavity of the housing 110. Hasps and corresponding latches are well known to one of ordinary skill in the art. Other lock standard components (e.g., key sleeve 130) are disposed in the inner cavity of the housing 110. As shown in FIG. 1, the key sleeve 130 is positioned in between the first end and second end of the curved lock 115 and the keyhole is disposed in the top surface 111 of the housing 110. As shown in FIG. 5A, the keyhole is disposed in the bottom surface 112 of the housing 110.
The first shaft in the housing 110 comprises a first heating element 120a. The first heating element 120a is coiled around the portion of the first end of the curved lock 115 that is disposed in the inner cavity of the housing 110. The second shaft in the housing 110 comprises a second heating element 120b. The second heating element 120b coils around the second end of the curved lock (when the second end of the curved lock is in the second shaft). The key sleeve 130 comprises a third heating element 120c, which coils around the key sleeve 130. The heating elements 120 are evenly wrapped around the shafts or key sleeve 130 to heat evenly.
The heated lock device 100 of the present invention further comprises a power source, for example a battery 160. In some embodiments, the battery 160 is a lithium battery (e.g., button cell battery) or a rechargeable battery. The power source (e.g., battery 160) is housed in a battery compartment (165) disposed in the housing 110. As shown in FIG. 2, a battery-holding tray 170 is adapted to fit into (e.g., slide into) the battery compartment (165). In some embodiments, as shown in FIG. 1 and FIG. 2, the battery compartment (165) is positioned near the bottom surface 112 of the housing 110. FIG. 3 shows the battery compartment (165) with the power source (e.g., battery 160) is positioned below the key sleeve 130. The battery compartment (165) and power source (e.g., battery 160) is not limited to this position. For example, FIG. 5A shows the battery 160 positioned near the top surface 111 of the housing 110. In some embodiments, a door 150 is pivotally attached to the housing 110 and can move between an open position and a closed position for respectively allowing and preventing access to the battery compartment (165).
The activation of the heating elements 120 is regulated. In some embodiments, the activation means is a spring-loaded mechanism. As shown in FIG. 5, the key sleeve 130 is slidably disposed in the inner cavity of the housing 110. The first end of the key sleeve 130 is positioned at the top end of the housing 110. The second end of the key sleeve 130 extends in the inner cavity of the housing 110 into a spring recess chamber 510. Disposed on the second end of the key sleeve 130 is a stopper 520 which functions to compress a spring 530 disposed in the spring recess chamber 510.
Disposed on the stopper 520 is a pressure spring bar 540. The spring 530 is coiled around the pressure spring bar 540. The pressure spring bar 540 is slidably in contact with a heat transformer 550 disposed above the power source (e.g., battery 160). As shown in FIG. 5, the heat transformer 550 is disposed above the battery 160, and a base contact plate 260 is disposed below the battery 160. The heat transformer 550 is operatively connected to the power source (e.g., battery 160). The heat transformer 550 comprises a button 551. When the button 551 is pressed, the heat transformer 550 is activated, allowing current or heat to be transferred to the heating elements 120 (e.g., via wires). The pressure spring bar 540 can move between an up position wherein the pressure spring bar 540 contacts the heat transformer 550 by depressing the button 551 (activating the heat transformer 550) and a down position wherein the pressure spring bar 540 does not contact the heat transformer 550 (the button 551). The pressure spring bar 540 is biased in the up position caused by the spring 530. FIG. 3 shows the pressure spring bar 540 in the up position (not in contact with the heat transformer 550), and FIG. 5 shows the pressure spring bar 540 moving down to the down position (to be in contact with the heat transformer 550). As shown in FIG. 3, the first heating element 120a, second heating element 120b, and third heating element 120c are each operatively connected to the heat transformer via a wire.
As shown in FIG. 5A, a contact pin 210 is disposed at the end of the keyway 190. The contact pin 210 has a first end and a second end, the first end being disposed at the end of the key sleeve 130 and the second end extending toward the power source (e.g., battery 160). The contact pin 210 is movable between an up position wherein the second end of the contact pin 210 is not in contact with the power source (e.g., battery 160) and a down position wherein the second end of the contact pin 210 is in contact with the power source (e.g., battery 160). FIG. 5A shows the contact pin 210 in the down position contacting the battery 160. The contact pin 210 is biased in the inactive position caused by a spring 220. The spring 220 is disposed in a spring compartment 222 and is coiled around the contact pin 210. A stopper 230 is disposed on the contact pin 210 near the first end of the contact pin 210. The stopper 230 compresses the spring 220 when the contact pin 210 is moved to the down position. The contact pin 210 can be moved to the down position by inserting a key 105 into the key sleeve 130. When the key 105 is removed from the key sleeve 130, the spring 220 pushes upwardly on the stopper 230 to move the contact pin 210 back to the up position.
When the contact pin 210 contacts the power source (e.g., battery 160), current can flow from the battery 160 to the heating elements 120. When the contact pin 210 does not contact the power source (e.g., battery 160), the circuit is broken and no power is delivered to the heating elements 120. As shown in FIG. 5A, the heating element 120c is operatively connected to a base contact plate (which contacts a first terminal of the battery 160 via a first wire 125a. The heating element 120c is operatively connected to the contact pin 210 via a second wire 125b, the contact pin 210 being for contacting the second terminal of the battery 160.
Disposed in the housing are a first drain hole 410a, a second drain hole 410b, and a third drain hole 410c. As shown in FIG. 3, the first drain hole 410a extends from the inner cavity of the housing 110 near the first end of the curved lock 115 down to the bottom surface 112 of the housing 110. The second drain hole 410b extends from the inner cavity of the housing 110 near the second end of the curved lock 115 down to the bottom surface 112 of the housing 110. The third drain hole 410c extends from the key sleeve 130 of the housing 110 near the middle of the curved lock 115 down to the bottom surface 112 of the housing. The drain holes 410 allow condensation to drain from the inner cavity of the housing 110. For example, if the lock device 100 becomes frozen and the heating elements 120 are activated, the ice will condense in the inner cavity of the housing 110. The drain holes 410 allow this condensation to be drained. Also, the drain holes 410 help aerate the inner cavity of the housing 110.
