A vacuum gripper comprises a rigid base element and a loop-shaped vacuum seal element. The base element has first and second opposite sides. The seal element is attached at least indirectly to the second side and protruding therefrom in a direction away from the first side. The seal element comprises a contact surface that at least partially contacts with an object surface and an encircling surface oriented transversely to the contact surface so as to define a chamber. The seal element is elastically deformable at the contact surface to enable conforming to the object surface when pressed thereagainst. The vacuum gripper comprises an air extraction means mounted to the first side to be in fluid communication with the chamber through the base element, and configured to continuously extract air from the chamber to cause the contact surface to be urged towards and grip the object surface when pressed thereagainst.

The present disclosure relates to polishing tools and, more particularly, to hand polishing fixtures and methods of use. The structure includes: at least one hand grip which includes a shape accommodating a palm of an operator's hand; and a chuck having an interior space structured to fix a sample within the chuck and to extend below an underside surface of the at least one hand grip.

An extended frame portable vacuum grip device is provided having a rigid unitary support frame with elongated base and peripheral support wall that can define an open chamber at a face of the device for vacuum grip connections. A plurality of corresponding components can be combined to form independent vacuum grip regions within the open chamber extending along the length of the support frame. A plurality of ports can be defined through the base along its length that can each operatively connect with a corresponding pump. A plurality of closed-loop gaskets can each mate with corresponding portions of the base and support wall within the open chamber to act as vacuum seal members and define independent vacuum grip regions. A corresponding support frame for each gasket can help retain the independent arrangement and enhance seal actions of the gasket. The grip device can include structural reinforcements for reducing applied stresses.

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.

A detachable control handle for an extended grip system is provided for attachment with an interface of a portable grip device including a pair of spaced apart connector tabs extending from a rigid frame of the portable grip device and forming a pair of parallel captivation channels. The control handle can include an elongate grip handle and a pair of opposed support arms attached to the grip handle and extending away at angles from each other. The support arms can be more flexible in a perpendicular direction of the portable grip device. A crossarm can extend between the pair of support arms proximate a second end portion for establishing a preset inboard spacing maintaining the pins and support arms in an after-attached arrangement that can interfere with connecting and disconnecting. A method includes a user flexing the engagement members and pins for guiding the attachment.

The invention discloses a device (1) for releasing glasses (2) from the bodies (3) of vehicles where the device (1) comprises a frame (4), at least one suction pad (5), one guide pulley (6) fitted with two guide grooves (7) for guiding a cutting wire (8), or two guide pulleys (6) with a common central line, and two winding pulleys (9). The winding pulleys are fitted with winding grooves (10) for winding the cutting wire (8) and a spacing element or a spacing pulley (11) keeping the cutting wire (8) at a safe distance from the suction pad (5). During releasing the glass (2) the cutting angle (α) of the cutting wire (8) does not exceed the value of 90°. Each end of the cutting wire (8) is wound onto the winding pulleys (9) due to the guide grooves (7) wherein a safe distance from the suction pad (5) is ensured to eliminate their damage.

Aspects described herein include an end effector that includes a pliable body member defining an inner recess and having a sealing surface at a distal end. The sealing surface forms a seal with items and defines a first suction area. The end effector also includes an inflatable bladder that expands into the inner recess. When the bladder is in an inflated state, the bladder defines a second suction area smaller than the first suction area. The end effector also includes a vacuum port in fluid communication with the inner recess.

The subject of the invention is a suction pump having a suction tube and a suction piston for producing a negative pressure in a negative-pressure retaining device, a set consisting of the negative-pressure retaining device and the suction pump, and a method for attaching the negative-pressure retaining device.

A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which a vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with a vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum passageway.

A double ended hand tool created to pick up place and position flatback crystals, gems or other tiny items is disclosed. The tool contains a hollow, conical end which securely encases each crystal allowing the operator to easily position the crystal with no slip. The tool has a first end and a second end coupled by a shaft. The first end has a wax tip which allows the user to pick up crystals or other small items. The second end has a hollow narrow extended portion which allows the users to manipulate the crystal or other small items.
