A clip for sewing includes lower and upper members that are pivotable to each other about a given axis. The lower member has a first prong portion and a first handling portion opposite to the first prong portion. The upper member has a second prong portion and a second handling portion opposite to the second prong portion. A bias member urges the lower and the upper members about the axis so that the first prong portion and the second prong portion are drawn to each other to shut. A plurality of projection/recess pairs are provided, each pair having ng a recess and a corresponding projection to be received in the recess. In each of the projection/recess pairs, the recess is provided at one of the first and second prong portions, while the corresponding projection is provided at the other of them.

A straight edge bar clamp spreader comprises a straight edge bar, an inner channel portion, parallel channel portions, and two-way bosses or divots, a clamp, and a clamp-spreader. The inner channel portion is provided along an elongated central region of the bottom surface of the straight edge bar with a constant cross-section. The parallel channel portions are provided along two elongated parallel regions of the top surface of the straight edge bar. The two-way bosses or divots are provided across and on an inner surface of the inner channel portion of the bottom surface and an outer surface of the top surface and configured to define the predetermined stopping positions for two-way movements along the bottom surface or the top surface. The clamp is installed in the inner channel portion of the bottom surface. The clamp-spreader is installed in the pair of parallel channel portions of the top surface.

A toolless clamp comprises a shaft, a base, a latch, a first biasing member, and a clamping member. The base has a base bore configured and arranged to slidably receive a portion of the shaft. The latch has a latch bore configured and arranged to slidably receive a portion of the shaft and a portion of the base. The first biasing member is configured and arranged to bias the latch in a first direction away from the clamping member in an unclamped position and bias the shaft and clamping member in a second direction toward the base in a clamped position. The clamping member is operatively connected to a proximal end of the shaft and is configured and arranged to disengage the connecting member when the latch is in the unclamped position and engage the connecting member when the latch is in the clamped position.

A solar power system may include rails, solar modules, and a plurality of clamps to secure the solar modules to the rails. An end clamp may be partially disposed inside a rail at an end of the rail. The end clamp may secure a solar module to the rail by coupling to the frame of the solar module. The end clamp may include a fastener that may be tightened to engage the end clamp and secure the solar module by holding it on top of the rail. The end clamp may establish an electrical grounding connection between the frame of the solar module and the rail.

Fixture Apparatus and methods of manufacturing fixture apparatus. Fixture apparatus comprising: a first body to at least partially support an object, the first body including a structure having variable stiffness along at least a first axis of the first body.

A clamping device has a clamping arm mounted pivotable in a housing of the clamping device, a first locking means pivotable corresponding to the pivoting movement of the clamping arm, and a second locking means arranged in the pivot path of the first locking means and mounted in the housing, wherein the two locking means interact in an end position of the clamping arm. The first locking means, in the region of the end remote from the pivot axis of the first locking means, on the side facing the second locking means, has a recess defined at the side by two projections, wherein the second locking means contacts the projections when the clamping arm pivots into the end position thereof and is inserted into the recess in the end position, wherein the first locking means has a first portion which receives the first projection, and a second portion which receives the second projection, wherein the two portions, with the second locking means acting upon the two projections, are movable toward one another against a spring force with the spacing between the projections increasing.
