Abstract: An automatic locking mechanism can include one or more annular elements having teeth facing each other or facing away from each other. The automatic locking mechanism can include a rod disposed between the annular elements. The rod can have one or more pins configured to interface with the teeth of the annular elements. The pins and the teeth are also configured to rotate the rod when the annular elements move relative to the rod. The rotation of the rod can toggle a hook end of the rod in a hook receptacle, which can change states of the locking mechanism.

Abstract: A fork assembly can include multiple forks configured to surround a load. Multiple attachments can be made on the forks to couple to straps for support a load. The fork assembly can further include multiple fork extensions having end attachments to couple to straps for pulling on the load. Alternatively, the fork assembly can include multiple fork lifters having blades rotatable between a non-lift position and a lift position. The fork extensions can also have blades rotatable between a non-pullable position and a pullable position. The blade rotation can be performed by a remote rotate mechanism by an operator operating the fork assembly. In some embodiments, the fork attachment assembly for a forklift or a forklift vehicle can include roller legs coupled at far ends of the fork beams or the fork extensions. The fork assembly can include roller legs coupled at far ends of the fork beams or the fork extensions.

Abstract: A vacuum gripper for gripping an object surface using vacuum suction is configured to be portable or operated by a hoist. Battery conservation measures are included to provide a long term vacuum generation capability, together with manually rechargeable mechanism. A manually-operated vacuum pump is also integrated to the vacuum gripper as a safeguard for the battery-operated vacuum pump failure. The vacuum gripper includes an elastic deformable vacuum seal for gripping objects with irregular surfaces, together with press rods or pin array configured to assist the vacuum seal in filling any gaps between the vacuum seal and the object surface.

Abstract: A clamping device configured to handle large and fragile objects can include large jaws extended outside a smaller jaw support. The extended areas of the second jaw can be up to 4× of the jaw support, and can contain reinforced ridges configured so that a force applied from the second body portion to the second jaw spreads to the extended areas of the second jaw outside the second body portion, for example, to at least 80%. The clamping device can include an automatic locking mechanism for open and close the jaws from an operator far away from the clamping device.

Abstract: A panel joiner system includes 2 sets of suction cups couple together through a linear guide to allow the sets of suction cups to move toward each other for joining panels along the edges. A movement mechanism is also coupled to the suction cups to convert a rotational movement to a linear movement of the suction cups. A surface alignment module is coupled to the linear guide to move between the suction cups for aligning the top surface of the panels. Compressible materials or ball bearings can be disposed between the section cups and the linear guide to allow the panel joiner to adjust the panel positions for joining.

Abstract: Attachments for a clamping device can be used to increase the contact area between the jaws and the object to allow the clamping device to handle irregular objects, such as non-flat panels of metal, granite, ceramic, glass, quartz, or concrete plates. The attachments can include plate assemblies to be attached to the sides of the irregular objects. The attachments can include jaw plate assemblies to be attached to the sides of the jaws of the clamping device.

Abstract: A workstand support can have a height adjustment mechanism using a multi point locking system for simultaneously lock and unlock multiple locations in the height adjustment mechanism. Latch configurations of the multi point locking system can provide high surface areas for higher load support. Snap latches and spring loaded assemblies can provide means to secure the multi point locking system. Folded legs can reduce storage space for the workstand support.

Abstract: A clamping device includes a rotatable element disposed between a jaw and a jaw support. The rotatable element has a slanting surface, interfacing a roller, and thus is configured to push the jaw toward an opposite jaw of the clamping device when rolling in a clamping direction. An auto lock mechanism is included in the clamping device, which can secure the rotating element for keeping the jaws separated. The auto lock mechanism can be activated or deactivated when the jaws are separated at a maximum or near maximum separation.

Abstract: A clamping device is used for joining panels or boards with highly cosmetic appearance at the visible joined surface. The clamping device can include mechanisms to support and move one panel relative to another panel in two directions perpendicular to the beveled edges of the panels. The clamping device can include a rotational mechanism to rotate one panel around a direction parallel to the beveled edge.
