摘要:
The present invention provides a fastener alignment guide comprising a generally planar body and an angled element arranged at an acute angle θ to the body, a first aperture arranged through the angled element and a second aperture arranged through the body, wherein the first aperture and the second apertures are aligned such that a fastener may be inserted progressively through the first and second apertures in use. The present invention also provides a slip-resisting fastener alignment guide comprising a body at least partially arranged in a first plane, the body comprising a first aperture for receiving, in use, at least a portion of a shank of a fastener; and a guidewall extending out of the first plane for guiding the fastener, in use, into the first aperture at an acute angle α to the first plane, wherein the guidewall comprises a first bearing edge or surface upon which an underside of a head of the fastener can bear in use, the body further comprises a second bearing edge or surface upon which the underside of the head of the fastener can bear in use, and the first bearing edge or surface and the second bearing edge or surface are each configured/arranged to resist movement, in use, of the fastener alignment guide relative to the fastener in a first direction parallel to the first plane. The present invention also provides a method of forming the fastener alignment guide and slip-resisting fastener alignment guide.

A clip comprises a member mounting portion for attaching a mounting member; an umbrella shaped flange; a flat plate-like shaft extending downward from the center of the umbrella flange; a pair of arms extending obliquely downward and outward from the umbrella center; a pair of legs extending from the upper outer side to the lower inner side; and a pair of locking portions near the upper end of each leg and having a distance between the outer surfaces smaller than the distance between the outer surfaces of the upper ends of the legs. The distal end of each arm is connected to the middle of a leg. A leg connector connects the lower ends of the legs to each other. As the clip is pushed into the mounting hole, the upper portions of the legs move inward and the lower portions of the legs move outward.

The present disclosure is directed to a coupling element for the releasable connection of a first component to a second component. The coupling element has an annular basic element comprising a fastening structure at a radially outer side. Further, the basic element comprises a socket-like holding structure at a radially inner side. The socket-like holding structure comprises a centrally arranged supporting element as well as a plurality of holding webs. The holding webs comprise at least a first and a second web section. The first web section encloses with an axis of symmetry S of the coupling element an angle ∝ from a range of 45°≤∝≤90° and the first web section and the second web section are arranged in an obtuse angle with respect to each other.

A photovoltaic mounting system having an elongated connector base. The elongated connector base can included photovoltaic module connector portion for supporting a pair of elevated photovoltaic modules above the base. The base may include a captive screw system for holding a pair of mounting screws in place prior to installation and functioning as a screw guide during installation. An assistance clamp fits over the elongated base under the photovoltaic module connector portion to secure the elongated connector base to relatively narrow portion of a roof to provide lateral stability to the elongated connector base.

A device for removably connecting a lining layer to an inner shock-absorbing portion of a helmet, mainly made of foam is disclosed. The device includes a first element constrainable to the lining layer and a second element constrainable to the inner shock-absorbing portion. The second element has a threaded portion that can be inserted by screwing it in the foam of the inner shock-absorbing portion. The device also includes means for the mechanical snap-fit coupling between the first and the second element.

A method and apparatus is provided for adjusting a latch. An apparatus comprises a latch body, a first member, and a second member associated with the latch body. A receiving area extends through at least a portion of the latch body. The first member is configured to be at least partially received within the receiving area of the latch body. The first member has a first coupling element. The second member has a second coupling element. Movement of the first member along an axis through the receiving area changes a distance between the first coupling element and the second coupling element.
