The present invention relates to combination padlocks.
There are several combination padlocks with single or even dual locking mechanisms that are on the current market. However, most of these padlocks are traditionally shaped and have a mechanical combination mechanism such as Mr. Eric Lai's U.S. Pat. No. 5,715,709 and U.S. Pat. No 8,261,583. However, none of these existing padlocks show a combination padlock which contains an object shape such as a car. For example,

Combination Padlock Captures—
The new invention is a padlock 10 with a car shaped external-cover 20, base-cover 30, and a set of exterior-dials 110 that act as the vehicle tires. In addition, a locking means such as cable 50 with different lock-ends (fixed-end 51 and flexible-end 52) controlled by the mechanical mechanism such as the correct combination code via dial 110 or correct key 260, allows for opening and closing of the object shaped (car shaped) padlock. More than one unlocking feature can be added in such a padlock. The present invention uses a set of exterior-dials 110 which are mounted like a vehicle tire/wheel to form a car shaped locking padlock with physical functionality on the wheels. If at least one exterior-dial 110 is not in the correct code, then the entire locking mechanism cannot be opened via the combination mechanism. If a correct key 260 is not present, then the padlock 10 is also not able to be opened by the incorrect key.
A button 170 demonstrates the opening of the lock correct code of exterior-dial 110. If it is not correct as per
A wheel cover 140 is mounted in the exterior-dial 110 to serve as a decoration and to cover the internal mechanism of the combination mechanism.
In
Combination Mechanism Design and Placement
The object-shaped padlock 10 is constructed with a set of exterior-dials 110, such as dials 110 assembled by the inner-dials 120. There is a rivet 122 in the inner-dial 120 which is assembled into the rivet-hole 111 of the exterior-dial 110. Once it is riveted then rotational movement from the exterior-dial 110 will direct transfer to the inner-dial 120. There is a wheel-cover 140 which is assembled to the exterior-dial 110. There is a rivet-hole 142 of the wheel-cover 140 that has a bigger space to cover the rivet 122 and rivet-hole 111 once they are riveted. By doing so, the exterior dials 110 look nice at the exterior, such as shown in
The inner-wheel 120 contains ratchet-slots 124 which receive the ratchet-pins 181 which are held in place in the ratchet-pin-holder 180 with a spring 182 exerting a force to make sure the ratchet-pins 181 will always be in contact with the ratchet-pin slot 124 of the inner-wheel. The ratchet-slot 124 is held in place by an inner-wheel-slot 30f/40f of the base-body-30/interior-cover 40. Once it is in this position, the riveted exterior-dial 110 and the inner-dial 120 cannot be pulled away from the body and the cover 20/30/40.
The inner-wheel 120 further contains a set of teeth 121 which engage with the teeth-slot 131 of the clutch 130. The teeth are engaged all the time except in the reset mode. Once the teeth-slot 131 engages with the teeth 121, the rotation of the exterior-dial 110 will transfer to the inner-dial 120, and it will further transfer this rotational movement to the clutch 130. The clutch 130 contains a reset button 135 which travels and passes through the reset holes 123/141/112 of the inner-dial 120/wheel-cover 140/and exterior-dial 110. The clutch 130 contains a true-gate 132 and false gates 133. In the lock mode, when the true gate 132 of the clutch 130 does not align to the extended-fin 153 of the control-plate 150, the control-plate 150 cannot be moved and cannot let the lock change to the open status. In the lock mode, the clutch 130 has been rotated such that the false gate 133 aligns with the extended-fin 153. In this case, the control plate 150 can only move a small distance relative to the false gate area. This creates a faulty signal to an intruder so as not to be able to easily locate the true gate 132 of the clutch 130 to open the lock. The clutch 130 contains an assembled portion in the clutch-slot 39/48 of the base-body 30/interior-cover 40.
The control-plate 150 further comprises a curved-surface 151 which contacts the clutch 130 when the padlock 10 is in the locked mode. The clutch 130 further comprises a spring-hole 134 which lets the clutch spring 210 pass through that lets spring 210 to contact the clutch-spring-wall 30g of the base-body 30. Although the control-plate 150 will be moving around the control-plate-slot 38/47 within the base-body 30 and the interior-cover 40, the shape and design of the clutch-spring-hole 152 is such that the clutch spring 210 will always be pushing the clutch 30 toward the inner-dial 120 so that the teeth-slot 131 of the clutch 130 will always engage with the teeth 121 of the inner-dial 120. The clutch spring 120 will not interfere with the movement of the control-plate 150.
The control-plate 150 also contains at least one connected-plate-receiving-cutout 154 (two cutouts) where one end is connected with the extended-pointer 163 of the connected-plate. The other end of the connected-plate-receiving-cutout 154 is connected to the extended-wing 171 of the button 170. This means that the control-plate 150, the connected-plate 160, and the button 170 are assembled together with the same vertical movement. In this case, the vertical movement of the control-plate 150 is mainly by the alignment of the true gate 132 of the clutch and the extended-pin 153 of the control-plate 150. In the lock mode, since at least the true gate 132 and the extended-pin 153 are not aligned, the control-plate 150 cannot move to the lock open position. Then the control-plate 150, and the contact-wall 161 will remain in the lock position and thus will not push the tail 73 of the cam upward. This means the opening via combination is restricted.
There is a connected-plate spring 230 which is installed in between the spring-wall 162 of the connected-plate 160 and the connected-plate-spring-wall 30i. This spring 230 will always push the connected-plate 160/control-plate 150/and the button 170 downward away from the tail 73 of the cam 70.
There are two control-plates 150 and each control plate 150 looks after the one side set of dials (two dials for this invention). If the padlock contains six wheels, then the control plate 150 can be expanded to have 3 extended-pins 153 and 3 sets of clutch mechanisms on each side.
The cam 70 has a flat-edge 72 which in the lock mode will always align to the flat-end 61 of the bolt 60. The other side round-end 62 of the bolt engages with the bolt-receiving-cutout 53 of the flexible-end 52 of the cable unit 50. Since the control-plate 150 has no movement, then the cam spring 240 will push the cam downward to this lock position. There is a cam-spring-hole 71 to receive the cam spring 240 to let the spring push the cam downward all the time. In additional, there is a wing 54 of the fixed-end 51 of the cable unit 50 placed inside of the wing-slot 30g/40h of the base-body 30 and interior cover 40. Once this is in place, the fixed-end 51 of the cable 50 cannot move away from the fixed-end-hole 21/31/41 of the external-cover 20/base-body 30/and interior cover 40 in any mode.
In the lock mode, pushing the reset button 135 of the clutch 130 will not lead to the reset mode, since the curved-surface 151 of the control-plate 150 will block the clutch 130 from moving inward.
Key Mechanism Design and Placement
A cylinder 100 is placed in the padlock 10. The cylinder may be controlled by a stack of wafers, such that when the correct key 260 is not present, the stack of wafers extending outwards prevent the cylinder from turning and opening the lock. The cylinder 100 contains pins 101 which are assembled to the holes 92 of the short-cam 90. The slope 91 of the short-cam 90 contacts the slope 82 of the extended-cam 80 for lock opening via key mechanism usage. Since there is no rotation of the cylinder 100, the short-cam 90 and the extended-cam 80 will have no movement. As they have no movement, then the cam 70 will have no movement.
There is an extended-cam spring 220 which is installed in between the wall 83 in the extended-cam 80 and the extended-cam-spring-wall 30j of the base body 30. This spring 220 will always push the extended-cam 80 downward such that the tail 81 of the extended-cam 80 will stay away from the tail 73 of the cam 70 in the lock mode. The spring 220 will also make the extended-cam 80 push downward such that the slope 82 of the extended-cam 80 will engage with the slope 91 of the short-cam during in the lock mode.
Unlock by Combination Code (
Since the user can turn the exterior-dials 110, the inner-dials 120 turn in the same manner as previously described so that each rivet 122 is being held in place in the rivet hole 111 of the exterior-dial such that they are assembled together with the same rotational movement. The teeth 121 of the inner-dial 120 engage with the teeth-slot 131 of the clutch 130, and as the inner-dial 120 turns, the clutch 130 will turn in the same manner. As the clutch 130 turns in the same manner, the user can turn the exterior-dial 110/inner dial 120 and the clutch 130 such that the true-gate 132 of the clutch 130 aligns with the extended-pin 153 of the control-plate to the lock open mode via combination code position. As they align, the user can push the button 170 such that the extended-pin 153 of the control-plate 150 will be able to move upward into the true-gate 132 of the clutch 130. The extended-wing 171 of the button 170 is assembled to one of the connected-plate-receiving-cutouts 154 of the control-plate 150. Therefore, when all of the true gates 132 of the clutch 130 align with the extended-pins 153 of the control-plate 150, the button 170 can push upward to let the extended-pins 153 enter and move inward to the true-gate 132 of the clutch 130.
The other end of the connected-plate-receiving-cutout 154 is linked to the extended-pointer 163 of the connected-plate 160. As the button 170 is being pushed upward, so will the control-plate 150 and connected-plate 160. As the connected-plate 160 moves upward, the contact-wall 161 will contact the tail 73 of the cam 70 to drive the cam upward. A torque spring 200 is assembled in between the torque-spring-slot 33/43 of the base body 30/ interior-cover 40 and the torque-spring-slot 191 of the spring-load-member 190. As the cam 70 moves upward, the torque spring 200 will drive the spring-load-member 190 upward. As the spring-load-member 190 moves upward and the cam is being push upward, the round-end 62 of the bolt 60 will move leftward such that the round-end 62 of the bolt will disengage away from the of the bolt-receiving-cutout 53 of the cable 50. The flexible-end 52 of the cable will pop out of the flexible-end-hole 22/32/42 of the external-cover 20/base-body 30 and interior-cover 40.
The spring-load-member 190 contains an extended-fin 193 which is assembled inside of the spring-loaded-member-slot 30e/40e of the base-body 30 and interior-cover 40. This causes the extended-fin 193 spring-load-member 190 to move within the slots 30e/40e.
The round-end 62 of the bolt contacts the surface 192 of the spring-load-member 190 and the flat-end 61 of the bolt 60 is placed under the slope 74 of the cam 70 in the lock open mode via combination dials.
Meanwhile, as the button 170 is being pushed upward to open the lock via combination dials, two things could happen:
1. Jumping to reset mode described in reset mode section.
2. The user releases the push button, then the connected-plate-spring 230 will push the connected-plate downward such that the connected-plate 160, button 170, and the control-plate 150 will all be pushed downward as they are interconnected. The connected-plate-spring 230 is assembled in between the connected-plate-spring-wall 30i base-body 30 and the spring-wall 162 of the connected-plate 160. As the user releases the button 170, the spring will push the connected-plate downward. Although, the connected-plate 160 is being pushed downward, the flat-end 61 of the bolt 60 is being engaged underneath the slope 74 of the cam 70. Then the cam 70 will stay in the lock open position. Meanwhile, the extended-pin 153 of the control-plate 150 will disengage away from the true-gate 132 of the clutch 130. As it disengages, then the user can rotate the exterior-dials 110 and it will rotate the inner-dial 120 and the clutch 130. As these parts are being rotated, the true-gate 132 of the clutch 130 leaves the cam 70 in the lock open stage. This will cause the lock to be in the open mode, but as the exterior-dials rotate then it will show with a non-open code such that any intruder will not be able to peek the correct code from the lock opening mode, thus providing for better security.
As the button 170/ connected-plate 160/control-plate 150 falls downward, the curved-surface 151 will be blocking the clutch 130 and thus moving toward the reset position. This means that the user cannot push the reset button 135 of the clutch 130 to the reset position.
For the key mechanism, if the cylinder 100 does not have the correct key 260, then the cylinder does not rotate. As the cylinder does not rotate, the short-cam 90 and extended-cam 80 remain silent. The extended-cam spring 220 will tightly push the wall 83 of the extended-cam 80 toward the short-cam 90 and the cylinder 100. There is no action by these components during the entire lock open mode via combination dials.
To relock, the user can push the flexible-end 52 of the cable 50 into the flexible-end-hole 22/32/42 of the external-cover 20/ base-body 30/ interior-cover 40. Then the flexible-end 52 will push the spring-load-member 190 downward such that the bolt-receiving-cutout 53 aligns with the round-end 62 of the bolt 50. As they align then the cam spring 240 will push the cam 70 downward such that the slope 74 of the cam 70 will push the flat-end 61 of the bolt rightward such that the round-end 62 of the bolt will engage back to the bolt-receiving-cutout 53 of the cable 50. As they engage, the flat-end 61 of the bolt 60 will contact flat-edge 72 of the cam 70, and it will further confirm the engagement of the bolt-receiving-cutout 53 of the cable 50 and the round-end 62 of the bolt 60. The user can now scramble the exterior-dials 110 or readvance scramble the exterior-dials 110 as mentioned above once the button 170 is released.
Unlock by Key User (
When correct key 260 is inserted into the cylinder 100, the user can turn the cylinder 100. The pins 101 of the cylinder 100 are assembled with the holes 92 of the short-cam 90. As the cylinder 100 turns, the short-cam 90 turns in the same manner. As the short-cam 90 turns, the slope 91 of the short-cam 90 will drive the slope 82 of the extended-cam 80 upward in the same manner. The extended-cam 80 is placed inside of the extended-cam-slot 36 of the base-body 30. The slot 36 will prevent the extended-cam 80 from any rotational movement as the tail 81 of the extended-cam 80 is shaped like a square with the slot 36 also in a square shape which will prevent the extended-cam 80 from rotational movement. Therefore, as the slope 91 of the short-cam 90 turns, it only drives the slope 82 of the extended-cam 80 upward. As the extended-cam 80 moves upward, the tail 81 will contact the tail 73 of the cam 70 upward.
As the cam 70 moves upward, the torque spring 200 will drive the spring-load-member 190 upward. As the spring-load-member 190 moves upward and the cam is being push upward, the round-end 62 of the bolt 60 will be forced to move leftward such that the round-end 62 of the bolt will disengage away from the of the bolt-receiving-cutout 53 of the cable 50. The flexible-end 52 of the cable will pop out of the flexible-end-hole 22/32/42 of the external-cover 20/base-body 30 and the interior-cover 40.
The spring-load-member 190 contains an extended-fin 193 which is assembled inside of the spring-loaded-member-slot 30e/40e of the base-body 30 and interior-cover 40. This will cause movement of the extended-fin 193 spring-load-member 190 to move within the slots 30e/40e.
The round-end 62 of the bolt will contact the surface 192 of the spring-load-member 190 and the flat-end 61 of the bolt 60 will be placed under the slope 74 of the cam 70.
The key unlocking user does not have to touch or activate the following components to open the lock via key 260: the exterior-dial 110, the inner-dial 120, clutch 130, control-plate 150, connected-plate 160, and button 170. These components remain silent in the entire open via key mode.
The user can keep on rotating the cylinder with a degree control by the angle-control-member 102 of the cylinder 100 and the cylinder-turning-angle-control-slot 40a.
Once it is opened via key mode, the key user can withdraw the key away from the cylinder 100 and the extended-cam spring 220 assembled in between the extended-cam-spring-wall 30j and the wall 83 of the extended-cam 80 so as to push the extended-cam 80 downward back to the lock position leaving the cam 70 in the lock open mode. The slope 82 of the extended-cam moves downward so as to rotate the slope 91 of the short-cam 90 back to the lock mode. This will cause the padlock to have the key-non-captive design such that the key is no longer captive in the lock during the entire unlock via key mode.
To relock: the user pushes the flexible-end 52 of the cable 50 into the flexible-end-hole 22/32/42 of the external-cover 20/base-body 30/interior-cover 40. Then the flexible-end 52 will push the spring-load-member 190 downward such that the bolt-receiving-cutout 53 will align with the round-end 62 of the bolt 50. As they align, the cam spring 240 will push the cam 70 downward such that the slope 74 of the cam 70 will push the flat-end 61 of the bolt rightward such that the round-end 62 of the bolt will engage back to the bolt-receiving-cutout 53 of the cable 50. As they engage, the flat-end 61 of the bolt 60 will contact flat-edge 72 of the cam 70, and it will further confirm the engagement of the bolt-receiving-cutout 53 of the cable 50 and the round-end 62 of the bolt 60.
As the cam 70 is pushed downward, the tail 73 of the cam 70 will now travel back to the lock mode position ready for unlock via key mode.
Reset Combination Code (
To reset the combination code, the lock must be in combination lock open code as per lock open via combination. As the combination user pushes the button 170 upward in the lock open mode, the user can keep holding the button 170 and stick a screwdriver or an object into the reset-stopper-hole 172 of the button 170 such that the button 170 will not fall back downward.
As the button 170/ connected-plate 160/control-plate 150 continues in this upward position, the curved-surface 151 will not block the clutch 130 to move toward the reset position. The extended-pin 153 of the control-plate 150 will always engage with the true-gate 132 of the clutch 130 in the reset mode. As the true-gate 132 has a length longer than the other gates, the extended-pin 153 engages with the reset mode all the time. As the true-gate 132 of the clutch 130 engages with the extended-pin 153, the clutch 130 will not be able to rotate during the entire reset mode.
The user can use a reset tool 250 (see
While the reset button is pushed inward, the user can rotate the exterior-dials 110 and the inner-dials 120 so as to rotate in the same manner. Once the user sets the new combination code, the user can remove the reset tool 250 and the clutch spring 210 will exert a force such that the teeth-slot 131 of the clutch 130 will engage back to the teeth 121 of the inner-dial 120. If all dials are in the new code, the user could further remove the object which is inserted in the reset-stopper-hole 172 of the button 170 such that button 170 will fall back down. As the button 170 moves downward, the control-plate 150 will move downward and the extended-pin 153 will move away from the true-gate 132.
The user can scramble the dials to relock and the lock is set to use the new code.
The object lock need not be a car but can also be another object, such as an animal, for example, a dog as shown in
A combined-dial 270 is shown in
1. Teeth 271 which are similar to 121 teeth of inner-dial 120 and which have the same functionality as described above.
2. Reset hole 272 which is similar to reset hole 112/123of the exterior/inner dial 110/120 and which has the same functionality as described above.
3. Ratchet-slot 273 which is similar to ratchet-slot 124 of the inner-dial 120 and which has the same functionality as described above.
Third Embodiment of using combined dial and new rod
The new rod 280 is a replacement of spring-load-member 190. The torque spring 200 will now replace by rod spring 290.
The third embodiment is an improvement by combining using the combined dial 270 and the new rod 280 with a spring 290 to push the flexible-end 52 of the cable 50 out more smoothly and easily. The spring 290 is being placed in the spring-receive-cutout 281 of the rod 280. The spring 290 will push the rod 280 upward and the flexible-end 52 upward in the unlocking modes. The functionality of the rod 280/rod spring 290 will be exactly the same for the spring-load-member 190/torque spring 200.
