The present invention relates generally to lock mechanisms. More particularly, the present invention relates to a lock mechanism that can be used to lockingly secure and release sections of a device relative to one another, wherein the device can adopt different positions for functioning as a ramp, a trailer, or a transportation system for recreational vehicles, such as motorcycles.
U.S. Pat. No. 8,123,455 titled “Loading Ramp and Trailer” and granted Feb. 28, 2012 discloses a loading ramp and trailer. U.S. Pat. No. 8,123,455 is owned by the owner hereof and is hereby incorporated by reference. Specifically, U.S. Pat. No. 8,123,455 discloses an apparatus that can function as a ramp in one position and as a trailer in another position. The apparatus includes a plurality of sections that can rotate relative to one another and can be secured relative to one another in a plurality of positions. For example, the apparatus and the plurality of sections thereof can be moved into a loading one of the plurality of positions to function as a ramp, into a trailing one of the plurality of positions to function as a trailer, and into a transporting one of the plurality of positions, which is different from the loading one of the plurality of positions and the trailing one of the plurality of positions. In each of the plurality of positions, the plurality of sections of the apparatus can be locked in a respective one the plurality of positions relative to one another. However, to move between the plurality of positions, the plurality of sections of the apparatus can be released so that they can rotate relative to one another.
In view of the above, an improved lock mechanism that can be used to lockingly secure and release the plurality of sections of the apparatus relative to one another is desired.
While this invention is susceptible of an embodiment in many different forms, there are shown in the drawings and will be described herein in detail specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention. It is not intended to limit the invention to the specific illustrated embodiments.
Embodiments disclosed herein include a lock mechanism that can be used to lockingly secure and release sections of an apparatus relative to one another. For example, in some embodiments, the lock mechanism disclosed herein can lockingly secure the sections of the apparatus in any configuration or position that the sections can achieve relative to one another in a plurality of different positions. Thus, a user can achieve a desired configuration of the apparatus rather than choosing from a limited number of positions for the apparatus. In some embodiments, the lock mechanism disclosed herein can also be released or unlocked to allow the sections of the apparatus to rotate relative to one another and to different ones of the plurality of different positions.
The lock mechanism disclosed herein can be used in connection with the loading ramp and trailer as disclosed in U.S. Pat. No. 8,123,455. However, it is to be understood that the lock mechanism is not so limited. Instead, the lock mechanism disclosed herein can be used in connection with any apparatus as would be known by those of skill in the art that requires locking sections of the apparatus in a plurality of different positions and releasing the sections to move them relative to one another and to different ones of the plurality of different positions. For example, the lock mechanism can be used with a vehicle that includes folding sections or with an apparatus that functions as a ramp and a trailer for storing and transporting vehicles, such as motorcycles, all-terrain vehicles, snowmobiles, or jet skis. Indeed, the lock mechanism can lockingly secure and release the sections of the apparatus to accommodate vehicles of different sizes and dimensions and position the apparatus relative to vehicles of different sizes and dimensions and in different environments.
As seen in the figures, and most notably in
As seen, the lock mechanism 100 can include at least a first sub-assembly 110, a second sub-assembly 120, a third sub-assembly 130, a fourth sub-assembly 140, and a wedge assembly 150. The first sub-assembly 110 can be securely connected to the first section 210 of the apparatus 200 with which the lock mechanism 100 is used. The first sub-assembly can also be rotatably connected to the wedge assembly 150 via a connection mechanism 160 that can form an axis of rotation for the wedge assembly 150. For example, the wedge assembly 150 can include a wedge handle 152 that can be associated with and dissociated from the first sub-assembly 110 as needed.
The second sub-assembly 120 can be rotatably connected to the first sub-assembly 110 via a connection mechanism 162 that can form an axis of rotation for the second sub-assembly 120. The second sub-assembly can also be connected to the third sub-assembly 130 via an adjustable connection mechanism 164. For example, the connection mechanism 164 can be adjusted to adjust the tension between the second sub-assembly 120 and the third sub-assembly 130 as needed.
The third sub-assembly 130 can be rotatably connected to the fourth sub-assembly 140 via a connection mechanism 168 that can form an axis of rotation for the third sub-assembly 130. Finally, the fourth sub-assembly 140 can be rotatably connected to the second section 220 of the apparatus 200 via a connection mechanism 166 that can form an axis of rotation for the fourth sub-assembly 140. In some embodiments, the fourth sub-assembly 140 can include a spring loaded pin lock 142 that can be engaged to lock the mechanism 100 and secure the third sub-assembly 130 to the fourth sub-assembly 140 and/or secure the fourth sub-assembly 140 to the second section 220 of the apparatus 200 and that can be disengaged to unlock the mechanism 100 and to release the third sub-assembly 130 from the fourth sub-assembly 140 and/or to release the fourth sub-assembly 140 from the second section 220 of the apparatus 200.
As best seen in
To unlock the mechanism 100, a user can disengage the pin lock 142 by pulling on the pin lock 142. In some embodiments, the pin lock 142 can be spring loaded.
When the pin lock 142 is disengaged, the third sub-assembly 130 can rotate relative to the fourth sub-assembly 140 about the axis of rotation defined by the connection mechanism 168. Further, the second sub-assembly 120 can rotate relative to the first sub-assembly 110 about the axis of rotation defined by the connection mechanism 162. As best seen in
When the lock mechanism 100 is unlocked, as the third sub-assembly 130 rotates relative to the fourth sub-assembly 140, as the second sub-assembly 120 rotates relative to the first sub-assembly 110, and as the second section 220 rotates relative the first section 210, other sections of the lock mechanism 100 can be moved for securing the first and second sections 210, 220 of the apparatus 200 relative to one another in a second position, for example, in a partially unfolded position that would be suitable for the sections 210, 220 of the apparatus 200 acting as a ramp. For example, as best seen in
In some embodiments, the wedge assembly 150 can be spring loaded so that a spring is compressed when the wedge assembly 150 is in the first position and decompressed when the wedge assembly is in the second position. Accordingly, the first sub-assembly 110 can secure the wedge assembly 150 in the first position and when released therefrom, the wedge assembly 150 can be biased for moving to the second position. The wedge assembly 150 can remain in the second position until user intervention causes the assembly 150 to move back to the first position and be secured by the first sub-assembly 110.
When the lock mechanism 100 is unlocked and the wedge assembly 150 is in the second position, the third sub-assembly 130 can continue rotating relative to the fourth sub-assembly 140, the second sub-assembly 120 can continue rotating relative to the first sub-assembly 110, and the second section 220 can continue rotating relative the first section 210 until the first and second sections 210, 220 of the apparatus 200 are in the second position, for example, in a partially unfolded position that would be suitable for the sections 210, 220 of the apparatus 200 acting as a ramp. As best seen in
The lock mechanism 100 can be unlocked to release the first and second sections 210, 220 of the apparatus 200 from the second position, and when released, the third sub-assembly 130 can continue rotating relative to the fourth sub-assembly 140, the second sub-assembly 120 can continue rotating relative to the first sub-assembly 110, and the second section 220 of the apparatus 200 can continue rotating relative to the first section 210 of the apparatus 200. When the lock mechanism 100 is unlocked, as the third sub-assembly 130 rotates relative to the fourth sub-assembly 140, as the second sub-assembly 120 rotates relative to the first sub-assembly, and as the second section 220 rotates relative to the first section 210, other sections of the lock mechanism can be moved for securing the first and second sections 210, 220 of the apparatus 200 relative to one another in a third position, for example, in a completely unfolded position that would be suitable for the sections 210, 220 of the apparatus 200 acting as a trailer. For example, as best seen in
When the lock mechanism 100 is unlocked and the wedge assembly 150 is in the first position, the third sub-assembly 130 can continue rotating relative to the fourth sub-assembly 140, the second sub-assembly 120 can continue rotating relative to the first sub-assembly, and the second section 220 can continue rotating relative to the first section 210 until the first and second sections 210, 220 of the apparatus 200 are in the third position, for example, in a completely unfolded position that would be suitable for the sections 210, 220 of the apparatus 200 acting as a trailer. As best seen in
When the lock mechanism 100 is in position to facilitate the first and second sections 210, 220 of the apparatus 200 being in the third position, a force vector can be created along an axis of the mechanism 100. For example, as seen in
A user can apply a force to the fourth sub-assembly 140 in the direction shown by the force arrow in
In some embodiments, a user can also engage the pin lock 142 to lock the mechanism 100. Furthermore, in some embodiments, a user can adjust the connection mechanism 164 as needed to adjust the tension between the second sub-assembly 120 and the third sub-assembly 130, thereby adjusting the locking pressure of the mechanism 100. For example, the connection mechanism 164 can include a bolt and screw, and the bolt can be threaded along the length of the screw to adjust a distance between the second sub-assembly 120 and the third sub-assembly.
In some embodiments, the lock mechanism 100 can comprise first, second, third, and fourth lock components 110, 120, 130, 140 connected to each other in a progressive fashion with the lock mechanism 100 securing to the apparatus 200 via the first and fourth lock components 110, 140. As seen in
A second, opposite end of the second lock component 120 can be connected to a first end of the third lock component 130 via an adjustable connecting or spanning mechanism 164 that can maintain the second end of the second lock component 120 at a selected distance from the first end of the third lock component 130. A second, opposite end of the third lock component 130 can connect to a first end of the fourth lock component 140, and the third and fourth lock components 130, 140 can be secured via a second rotatable connection mechanism 168. For example, the second rotatable connection mechanism 168 can secure the third and fourth lock components 130, 140 together to allow them to rotate with respect to each other.
A second, opposite end of the fourth lock component 140 can be secured to a second device section 220 of the device 200 via a third rotatable connection mechanism 166, which can act as a second anchoring mechanism. For example, the third rotatable connection mechanism 166 can secure the fourth lock component 140 and the second device section 220 together so as to allow them to rotate with respect to each other.
Each of the first, second, and third rotatable connection mechanisms 162, 168, 166 can be any type of rotating attachment or fastening mechanism as would be known by those of ordinary skill in the art, for example, a pin, a bolt, or a screw. Furthermore, the spanning connection mechanism 164 can be any type of attachment or fastening mechanism suitable for securing components at a distance from each other and as would be known by those of ordinary skill in the art, for example, a bolt or a screw.
The lock mechanism 100 can be secured to the device 200 via a first anchor mechanism 160 attaching a first end of the lock mechanism 100 to the first device section 210 and via a second anchor mechanism 166 attaching a second end of the lock mechanism 100 to the second device section 220.
The first anchor mechanism 160 can secure the first lock component 110 to the first device section 210, and the second anchor mechanism 166 can secure the fourth lock component 140 to the second device section 220, with the second and third lock components 120, 130 therebetween for indirectly connecting the first and fourth lock components 110, 140 to each other.
After the lock mechanism 100 is secured to the first and second device sections 210, 220, the position of one (or more) of the first, second, third, and fourth lock components 110, 120, 130, 140 can be adjusted with respect to another while leaving intact secure connections between (i) the lock mechanism 100 and the first device section 210 and (ii) the lock mechanism 100 and the second device section 220. That is, a user can change the configuration of the lock mechanism 100 to a plurality of different positions without unsecuring the lock mechanism 100 from the device 200. Accordingly, the device 200 can be moved from a first position to a second position by loosening or unfastening any connection mechanism, moving one or more of the lock components secured by that connection mechanism, and re-securing or refastening that connection mechanism. In this manner, the user is not limited to simply one or two predetermined configuration options, but instead, can secure the lock components into any of the plurality of different positions they can achieve with respect to each other.
In some embodiments, the user can lockingly secure the lock mechanism 100 into any of the plurality of different positions that the first, second, third, and fourth lock components 110, 120, 130, 140 can achieve while connected to each other.
The user has many choices for adjusting positions of neighboring ones of the lock components with respect to each other, thereby enabling the user to choose from an almost infinite number of configurations for the lock mechanism 100.
One way to adjust the positions of the neighboring ones of the lock components can involve loosening or unfastening the rotatable connection mechanism joining or connecting the neighboring ones of the lock components to allow the user to rotate the neighboring ones of the lock components from defining a first angle to adopting a second angle. For example, while the lock mechanism 100 is secured to the device 200, the user can loosen the first rotatable connection mechanism 162 securing the first and second lock components 110, 120 to each other in a first configuration, rotate the first and second lock components 110, 120 from a first angle to a second, different angle defining a second configuration, and manipulate the first rotatable connection mechanism 162 to secure the first and second lock components 110, 120 into the second configuration. As desired, the user can manipulate the first rotatable connection mechanism 162 to allow for rotation of the first and second lock components 110, 120 to any angle achievable by thereby, and then manipulate the first rotatable connection mechanism 162 to secure the first and second lock components 110, 120 into a rigid, unmoving position.
As another example, while the lock mechanism 100 is secured to the device 200, the user can loosen the second rotatable connection mechanism 168 that joins and secures the third and fourth lock components 130, 140 to each other in a first configuration, rotate the third and fourth lock components 130, 140 from a first angle to a second different angle defining a second configuration, and manipulate the second rotatable connection mechanism 168 to secure the third and fourth lock components 130, 140 into the second configuration. In some embodiments, an engagement between a groove 90 in the third lock component 130 and the third rotatable connection mechanism 166 can limit the amount of movement achievable by the third and fourth lock components 130, 140 with respect to each other, for example, as seen in
As another example, while the lock mechanism 100 is secured to the device, the user can loosen the third rotatable connection mechanism 166 that secures the fourth lock component 140 to the second device section 220 a first configuration, rotate the fourth lock component 140 and the second device section 220 from a first angle to a second, different angle defining a second configuration, and manipulate the third rotatable connection mechanism 166 to secure the fourth lock component 140 and the second device section 220 into the second configuration.
A different, non-rotational method to adjust the positions of the neighboring ones of the lock components can involve loosening the spanning connection mechanism 164 securing the second and third lock components 120, 130 to each other at a first distance, adjusting the first distance to a second distance, and fastening the spanning connection mechanism 164 to secure the second and third lock components 120, 130 to each other at the second distance.
As explained above, when the lock mechanism 100 is in a non-rigid and unlocked position, adjacent ones of the lock components having a rotatable connection mechanism therebetween can rotate relative to each other in a range of angles. The adjacent ones of the lock components can be aligned with respect to each other at any of those angles and fastened into a rigid and locked position at one of those angles. Instead of each pair of the adjacent ones of the lock components being lockable into only one, two, or a limited number of positions relative to each other, each pair of the adjacent ones of the lock components can be arranged to define either (i) any angle within the range of angles provided by the rotatable connection mechanism or (ii) any distance within a range of distances provided by a spacing element, thereby providing pairs of the adjacent ones of the lock components that are able to assume a large number of positions.
As the lock mechanism 100 can include several pairs of the adjacent ones of the lock components that are adjustably joined to each other (e.g., 110 and 120, 130 and 140, and 140 and 220), the lock mechanism 100 can be moved and secured into a large number of positions, such as dozens, hundreds, or even an infinite number of positions. As the distance between at least one pair of the adjacent ones of the lock components (120 and 130) can be adjusted by the spanning connection mechanism 164, such pair can be positioned into any distance apart achievable by the spanning connection mechanism 164, and that pair can be locked into a rigid and secured position at any of those distances, for example, either touching each other or secured at a fixed distance apart from each other. Thus, the lock mechanism 100 can be locked into a rigid position in any configuration that its individual pieces can achieve.

In some embodiments, the fourth lock component 140 can include a spring loaded pin lock 142 that can be engaged to lock the lock mechanism 100 and secure the third lock component 130 to the fourth lock component 140 and/or secure the fourth lock component 140 to the second section 220 of the device 200 and that can be disengaged to unlock the lock mechanism 100 and to release the third lock component 130 from the fourth lock component 140 and/or to release the fourth lock component 140 from the second section 220 of the device 200.
To secure the first and second device sections 210, 220 relative to one another, the pin lock 142 can be engaged so that the third lock component 130 is secured relative to the fourth lock component 140 and/or so that the fourth lock component is secured relative to the second device section 220. To unlock the lock mechanism 100, a user can disengage the pin lock 142 by pulling on the pin lock 142. In some embodiments, the pin lock 142 can be spring loaded.
When the pin lock 142 is disengaged, the third lock component 130 can rotate relative to the fourth lock component 140 about the axis of rotation defined by the second rotatable connection mechanism 168. As seen in
In some embodiments, the user can also engage the pin lock 142 to lock the lock mechanism 100. Furthermore, in some embodiments, the user can adjust the spanning connection mechanism 164 as needed to adjust the tension between the second lock component 120 and the third lock component 130, thereby adjusting a locking pressure of the lock mechanism 100. For example, the spanning connection mechanism 164 can include a bolt and a screw, and the bolt can be threaded along a length of the screw to adjust a distance between the second locking mechanism 120 and the third locking mechanism.
