| 20120043777 | PARALLEL PNEUMATIC GRIPPER - The invention relates to a pneumatic gripper which comprises a gripper body ( | 02-23-2012 |
| 20120080896 | PNEUMATICALLY CONTROLLED GRASPING DEVICE - A pneumatically controlled grasping device to grasp and handle items or bodies provided with a graspable member. A supporting sleeve ( | 04-05-2012 |
| 20130088030 | METHOD AND APPARATUS FOR MANIPULATING A SUBSTRATE - A device is disclosed for manipulating a substrate having an inside diameter (ID). The device includes a handle, a trigger that slides within the handle, an alignment shaft and a plurality of substrate supports having distal ends. A plurality of substrate support actuators are connected to the trigger. The trigger can move the plurality of substrate supports between a substrate engaging position and a substrate releasing position through selective engagement of the plurality of substrate supports by the plurality of substrate support actuators. In the substrate engaging position the distal ends of the substrate supports move radially outward to engage the ID of the substrate, enabling the device to hold the substrate without touching the substrate faces. Other embodiments are described and claimed. | 04-11-2013 |
| 20130285403 | APPARATUS AND METHOD FOR ENGAGING AND HANDLING ARTICLES OF MANUFACTURE - Apparatus and method for engaging an article. The apparatus has a longitudinal centerline, a disengaged configuration and an activated configuration. The apparatus also includes a base having a first end and a second end and a sleeve surrounding at least a portion of the base. The sleeve has one or more bands extending between a proximal end and a distal end, the proximal end of the sleeve being joined to the base at a fixed location and the distal end of the sleeve being moveable with respect to the proximal end along the base. At least one of the band bends away from the longitudinal centerline when the distal end of the sleeve is moved toward the proximal end of the sleeve along the base from the disengaged configuration to the activated configuration. | 10-31-2013 |
| 20130300142 | ENGAGEMENT ASSEMBLY AND METHOD - An engagement assembly, adapted to securely engage an orifice of an article. The engagement assembly includes a plurality of elongate fingers which are transversely movable relative to each other, each finger having an end flange thereon. The engagement assembly has an insertion position, wherein said fingers are contracted together, such that said flanges are adapted to be inserted through said orifice of said article; and, an engaged position, wherein said fingers are flared outwards relative to said insertion position, such that said flanges are adapted to thereby prevent withdrawal of said assembly from said orifice. | 11-14-2013 |
| 20140138971 | CLAMPING MECHANISM - A clamping mechanism includes a supporting seat, a clamping assembly, and a pushing assembly. The clamping assembly includes a fixing member, four clamping members, and a limiting member. The fixing member is fixedly received in the supporting seat and defines a receiving hole therein. The four clamping members are partially received in the receiving hole and protrude out of the fixing member. The limiting member is sleeved around the four clamping members. The pushing assembly includes an adjusting seat, an elastic member, and a pushing member. The elastic member is received in the adjusting seat. The pushing member is partially received in the adjusting seat, and an end of the pushing member away from the adjusting seat is surrounded by the four clamping members and resists the four clamping members outwardly. | 05-22-2014 |
| 20140265400 | CENTER EXPANDING CHUCK - A system for handling an object comprises a guide plate, a center hub rotatable relative to the guide plate, a plurality of slots disposed in the guide plate, and a plurality of arms each having first and second ends. The first end of each of the plurality of arms is coupled to the center hub, and the second end of each of the plurality of arms is coupled to an associated slot of the plurality of slots. Rotation of the center hub in a first direction causes the second end of each of the plurality of arms to move radially outward within the associated slot in an extended state. An outer surface of a first arm of the plurality of arms may be nested against an inner surface of a second arm of the plurality of arms in a retracted state. | 09-18-2014 |
| 20150357062 | GRIPPER MECHANISM - A gripper mechanism for moving an object having a surface cavity, the gripper mechanism comprising an actuation end moveable in an axial direction and a rotary body. A first mechanism is configured such that movement of the actuation end in an axial direction rotates the rotary body. A gripper is moveable between an engaged position and a disengaged position. In the engaged position the gripper is capable of engaging an object and in the disengaged position the gripper is capable of being received into and removed from a cavity of an object. The gripper is connected to the rotary body by a second mechanism. The second mechanism is configured such that rotary motion of the body moves the gripper between the engaged position and the disengaged position. | 12-10-2015 |
| 20160016349 | DEVICE FOR TRANSPORTING A HOLLOW BODY COMPRISING IMPROVED GRASPING MEANS - A device for transporting a hollow body having a neck including an inner vertical orientation wall and a top edge, the device including elements for grasping the hollow body by engaging with the neck's inner wall, which are mounted at the bottom end of a rod and movably connected to the rod, the rod being movably mounted vertically between a high position and a low position. The grasping elements are movably mounted radially between: a retracted position, in which the grasping elements are inserted vertically, from top to bottom, inside the neck, without contact with the inner wall; and a deployed position, in which the grasping elements engage with the inner wall of the neck, wherein changing the position of the grasping elements from the retracted to the deployed position is controlled by the vertical movement toward the bottom of the rod, from the high to the low position. | 01-21-2016 |
