摘要:
To mount articles onto two or more surfaces can be difficult if the relative position of the surfaces can vary due to for example manufacturing tolerances. This can cause high levels of residual stress in the mounting arrangement that especially in a high vibration environment can cause failures. Conventional mounting arrangements overcame this by complex or heavy designs, or by the use of methods such as shimming. This generally caused conventional designs to be expensive and cumbersome to fit. The disclosed arrangement comprises a simple and relatively inexpensive bracket and adjustable member, wherein the adjustable member can be adjusted to compensate for misalignment. After the bracket is fitted into position, the adjustable member can be positioned relatively to the bracket in such a manner that the bracket is fully supported by the adjustable member without any unwanted residual stress.

The invention relates to a securing device for a structural component to be secured to a panel with a tubular piece inserted into a penetration in the panel, into which tubular piece is inserted a screw, said screw being supported with its head on the one end of the tubular piece and holding the structural component with its threaded part, said structural component contacting the other end of the tubular piece, said tubular piece being screwed an optional distance into the penetration for axial adjustment. The tubular piece contains a distance detector, wherein, when the tubular piece is at a distance from the structural component, said distance detector is in its starting position projecting out of said tubular piece on its side facing away from the screw head and, when the tubular piece is in contact with the structural component, said distance detector is noticeably displaced out of the tubular piece.

A coupling apparatus for spanning a gap between a first structure and a second structure and fixedly coupling the first and second structures together. The coupling apparatus includes first and second coupling structures, an attachment member and a coupling member. The first coupling structure has an internally threaded cavity and is fixedly coupled to the first structure. The second coupling structure has an externally threaded body and an abutting flange. The externally threaded body threadably engages the internally threaded cavity, permitting the first and second coupling structures to cooperate to span the gap between the first and second structures such that the abutting flange abuts the second structure. The attachment member includes a threaded portion which extends through the first and second coupling structures and threadably engages the coupling member. The attachment member and the coupling member cooperate to generate a clamping force which is transmitted between the first structure, the first and second coupling structures and the second structure to thereby fixedly couple the first and second structures together. A method for fixedly coupling a first structure to a second structure is also provided.

A fastener and method for securing plywood to sheet metal comprises a head, and a shank with three distinct segments. The first segment is a threaded tip segment with a pierce point tip; the second segment is unthreaded; the third segment is threaded and extends from the unthreaded second segment to the fastener head. The method provides for use of a power tool to secure together a plywood sheet with a sheet metal stud using the fastener.

A device for mounting door frames, window frames and similar objects (1) at an adjustable distance from a support structure (2) has a tubular member (3) insertable into a through hole in the supported object (1), a screw menas (7) insertable into a hole (6) extending longitudinally through the tubular member (3), the tubular member (3) also including adjacent to a first end portion a restricting surface spaced from a resilient locking means (9), arranged to facilitate axial displacement of the screw head into a contact position with the restricting surface, but preventing withdrawal from this contact position. The second end portion of the tubular member (3) is arranged to form a preferably substantially disc-shaped abutment member (4), restricting the insertable distance of the tubular member (3) into the supported object (1). A portion of the tubular member (3), located adjacent to the abutment member (4), is arranged with means (9) for engagement with the internal surface of the surrounding hole in the supported object (1 ), said means (9) preferably comprising a screw thread or similar, arranged to be diametrically expanded into said engagement by insertion of the screw (7) into the hole (6) of the tubular member (3).

The invention relates to an adjustable securing means, preferably of metal, for joining two components (1,2) together. It comprises a holding element (3) which can be incorporated into an adapted hole in the component (1) at the side of the component (1) facing the component (2). The holding element (3) is provided with an internal thread and comprises a collar (8). The securing means further comprises a force-transmitting element (7) which is provided at least partially with an external thread and is screwable into the holding element (3) and has a through hole (8) with a stop (a) or the like at one end, the hole (8) being otherwise completely or partially formed with polygonal cross-section. The holding element (3) consists of a relatively narrow sleeve-like ring (6). The internally threaded holding element (3) comprises a lip projecting radially from its peripheral face and axially spaced from the collar and a lug (16) which lies in the plane of the collar (8) opposite the lip (12 ) and has a hole (18).

A tolerance compensating element for a device for connecting components by a connecting screw, includes an inner and an outer threaded part (10, 12), which are in threaded engagement with one another and, together, form a length-adjustable spacer (14), and a sleeve (30) which is held in the inner threaded part (10) and holds a spring element (34) in a position in which it comes into frictional contact with the circumference of the inserted connecting screw, and an unscrew protection device (44) in the form of a ring that is rotatably supported at one end of the spacer (14) and includes at least one arm (48) which projects axially into the sleeve (30) and, at the free end, forms an outwardly cranked claw (50) against which a stop (54) formed on the sleeve (30) abuts when a maximum unscrewing distance of the inner threaded part (10) is reached.
摘要:
The invention relates to an apparatus for the compensation of tolerances between components to be screwed to one another, comprising a hollow-cylindrical base element and a hollow-cylindrical compensation element which is in threaded engagement with the base element and which can be moved from a starting position into a compensation position by rotation relative to the base element. The apparatus is characterized in that a fixing means is provided by which the compensation element can be fixed in the compensation position relative to the base element.
