Quick mounting nut

A fastener having a grip member ( ) that is insertable into a mounting space ( ) of a hollow structure ( ) and serves in the detachable fastening of an object to the hollow structure. The grip member ( ) is rotatable inside the hollow structure such that the grip member ( ) grips behind holding projections provided inwardly of the hollow body longitudinal walls. The holding projections are for fastening of the object between a stop ( ), that outwardly abuts the edges of the hollow structure's longitudinal walls ( ) lining the mounting space and can be fixedly clamped to the grip member ( ). A spring biased element ( ) acting perpendicular to the stop ( ) is arranged between the grip member and the stop. The result is that pre-fixation of the fastener to the hollow structure is made possible. By means of a coupling ( ) between the stop ( ) and the rear grip member ( ) its positions are precisely fixed.

Rail fastener

A connection element for at least two mounting rails ( ) and including a base member ( ) at least one attachment member having at least one connection opening ( ), and connection elements ( ) for reasonably connecting the attachment member ( ) with the base member ( ).

Connection element

A connection element for a bolt ( ) including a member ( ) for receiving the bolt ( ) and having a bore ( ) through which the bolt ( ) extends, a spring ( ) located in the bore ( ) of the receiving member ( ) for locking the bolt ( ) therein, and two, displaceable relative to each other, coaxial with each other and with the spring ( ), cone sleeves ( ) located in the bore ( ) of the receiving member ( ) and having each a through-bore ( ) which expands conically at its end adjacent to the spring ( ) and has a largest inner diameter, which is larger than an outer diameter of the spring ( ), and a smallest diameter which is smaller than the outer diameter of the spring ( ) but is at least equal to a diameter of the bolt.

A quick mounting nut ( ) movable, at least partially, without being rotated, axially to a threaded bolt ( ), with a springing wire clip ( ) being located in a nut housing ( ) with a continuous coaxial opening ( ), with the wire clip ( ) at least partially engaging in a bolt thread ( ) and having two legs ( &prime;) which spring relative to one another, with the opening ( ) having an inner cone ( ) which narrows radially from an axial neutral position of the wire clip ( ) and with the wire clip ( ) being movable axially to a limited extent and contacting at least partially inside the inner cone ( ) in its locking position.

A clamp for a cable duct having, at its open side (,), in regions of the free ends (,) of the side walls, inward projecting, strip-shaped edges, with the clamp including connection portions (,) provided at opposite longitudinal ends (,) of the bridge section (,) of the clamp, which bridges the open side (,) of the cable duct (,) being formed as inwardly bent, facing each other hooks lockingly engageable in undercuts (,) provided in respective anchoring grooves (,) extending in a longitudinal direction of the cable duct (,) and limited by respective bent-out portions (,) of respective side wall edges (,) and respective side walls (,).

A mounting rail, particularly for use in building construction, is formed by an elongated rail member (2) of approximately C-shaped cross section having a rear wall (3) with spaced openings (7a-7d) therethrough and pair of side walls (4a, 4b) extending from and at substantially right angles to the rear wall (3). The side walls have free edge sections spaced from the rear wall bent inwardly towards one another and forming cross members (5a, 5b) extending generally parallel to the rear wall with the inner edges of the cross members spaced apart and forming a slot (6) extending in the elongated direction of the rail member (2). Each side wall (4a, 4b) has shaped recesses (8a, 8b) extending for the length of the rail member (2). The shaped recesses (8a, 8b) are arranged symmetrically to one another in the opposite sidewalls (4a, 4b) and have a depth of (d) which does not exceed the width (b) of the cross members (5a, 5b) defining the slot (6).

A device for reinforcing a rear surface of a wall includes a receiving bag (4) attached to one end of an axial extending filling stub (1). Webs (3) are attached to the receiving bag (4) and the filling stub (1) so that the webs and receiving bag can be folded from a radially outwardly extending position toward the axis of the filling stub whereby the receiving bag and the webs can be folded into a position so that the combination of the webs (3), the receiving bag (4) and the one end of the stub (1) can be inserted through an opening (6a) in the wall (6). In the inserted position, the webs (3) return to the radially outwardly extending position along with the receiving bag (4) and the bag is filled with a hardenable mass (7) through the filling stub (1). A fixing element (5) is inserted between radially and circumferentially extending ribs (2) on the filling stub (1) located on the opposite side of the wall from the receiving bag (4). The fixing element (5) limits the depth that the filling stub (1) is inserted through the wall. After the mass (7) has hardened, a part of the wall (6) is reinforced at its rear surface by the mass, and fastening elements, such as screws, nails and the like, can be inserted through the wall into the hardened mass.

Arrangement for reinforcing parts of a wall with a hardenable mass

Attachment elements to be fixed to panel-shaped structural components by a hardenable material include an axially elongated dowel sleeve (1) forming a passageway extending from a second end toward a first end. An axially extending annular part (2) encircles the dowel sleeve. A bag-like member (3) is secured to the annular part and to the dowel sleeve adjacent the first ends thereof. The bag-like member is inserted through a borehole in the structural component from an outer side thereof. The bag-like member can be filled with a hardenable material providing a gripping action with an inner side of the structural component. The bag-like member, when filled with the hardenable material, has a first side facing the inner side of the structural component and an oppositely facing second side with openings in the first side being larger than the openings in the second side. As a result, when hardenable material is injected into the bag-like member, it flows out through the openings in the first side and supports the bag-like member with large area contact with the inner side of the structural component.
