摘要:
The apparatus is intended for vertically linking a first chain and a second chain under water. The apparatus is characterised in that it comprises a lower base (1) with an open cross-shaped slot (5) into which the last link of the first chain (6) is inserted, extending above said lower base (1), while a guide/holder (2) for the second chain (7) is attached to the lower base (I) over said slot, said guide/holder containing an H-shaped shackle (II) that is coupled to the last link of said second chain (7) by means of a first bolt (12), the last link of the first chain (6) being inserted in the free space in the shackle (11) so that both chains (6-7) are coupled by means of a second bolt (13).

The invention relates to a chain lock comprising two lock parts (1) which can be displaced in the longitudinal direction of the lock in order to open and close said lock. Each lock part (1) comprises a journal (5) which is arranged on one end thereof and a pocket (6) which is arranged on the other end thereof. The journal (5) of one lock part (1) fits, respectively, into the pocket (6) of the other lock part (1). The journals (5) and the pockets (6) are both similar in height (H) to the inner width of the lock and each journal (5) comprises several retaining frames (7, 8), whereby the several retaining grooves (13, 14) thereof are associated with the pocket (6) of the other lock part (1) in order to achieve economical power and voltage distribution in the journals (5) and pockets (6).

The present invention relates to a lifting hook (1) that can be used to lift loads using lifting gear, comprising a hook-shaped part (3) which hooks onto the load that is to be lifted and a chain length reducer (5) secured to the hook, the said reducer (5) comprising, on the one hand, an orifice (17) the dimensions of which allow the links of the chain (7) to pass through and then allow one (13) of the said links to be locked in position when the said chain (3) is taut and, on the other hand, means (21) for partially closing off the orifice (17) which are hinged so that they can be released manually simply by pressing them so as to allow the length of the chain (7) to be adjusted, notable in that the reducer (5) comprises a closure finger (10) that closes off the hook-shaped part (3) to prevent the load from becoming unhooked, and in that the closing-off means (21) comprise self-locking means (24) which hold the closure finger (10) in the locked position on the part (3) of the hook as long as the closing-off means (21) are disengaged from the orifice (17) and have not yet been returned to a position in which they bear against the external face (23).

The invention relates to a chain lock comprising two lock parts which can be displaced in the longitudinal direction of the lock in order to open and close said lock. Each lock part comprises a journal (6) which is arranged on one end thereof and a pocket (7) which is arranged on the other end thereof in order to receive a journal (6) of the respective other lock part. Each journal (6) is fitted with at least one retaining web (8) which can be displaced in a retaining groove (11) of the pocket (7) of the respective other lock part. The journal (6) and the pocket (7) have a cross-section which continuously widens or expands in the longitudinal direction of the lock in order to maintain the small amount of required displacement path in the opening and closing of the lock.

The invention relates to a plane chain strand (50) provided with horizontal and vertical normal chain links (30, 40) which are mounted in an alternating manner and which engage into each other in a nondetachable manner with the limbs and arcs thereof. In the chain strand (50), directly in front and directly behind a chain lock link (10), at least one special chain link (20) is mounted in the same position as said chain locking link (10). The limbs of the lock links have the same outer contour, especially the same width and thickness, as the outer limbs of the two lock parts of the chain lock link (10). The wear and tear of the chain lock link (10) of said inventive plane chain strand (50) can be reduced or eliminated in comparison with conventional plane chains, by means of equal or slightly larger previous and subsequent special chain links (20).
摘要:
Der Schäkel besteht aus zwei gleichen Schäkelteilen begrenzt durch längsgerichtete ebene Flächen, derart, daß die Schäkelteile in Längsrichtung zusammengeschoben werden können. Die beiden Schäkelteile sind im Prinzip U-förmig mit gleich langen Schenkeln. Der eine Schenkel (6) bildet jeweils eine flach gewölbte Längsseite, der andere Schenkel ist als Stumpf (20) ausgebildet. Beide Stümpfe bilden einen Steg zwischen den Kettenaufnahmen (1). In Richtung der Querachse (7) ist ein Bolzen durch Bohrungen in den Schenkeln und in den Stümpfen gesteckt. Der Bolzen ist durch Stifte (10) gesichert. Der Vorteil besteht in der Einfachheit der spanabhebenden Bearbeitung der geschmiedeten oder gegossenen Schäkelteile gegenüber dem bekannten Kenterschäkel.

Procédé d'assemblage de deux extrémités d'éléments en vis à vis et maillons démontables réalisés par ce procédé. L'invention a pour objet un procédé d'assemblage de deux extrémités d'éléments (1) en vis à vis à l'aide de deux demi coquilles (2) réunies par des organes d'assemblage tels que des vis. Selon l'invention, il comprend les étapes consistant à :
former des reliefs (3) soit à la surface interne des demi coquilles soit à la surface externe des extrémités des éléments; mettre les demi coquilles en place sur les extrémités des éléments; forger des reliefs sur les organes originellement lisses par estampage direct sur les organes possédant les reliefs; réunir les demi coquilles par lesdits organes d'assemblage.
摘要:
Der Bausatz für die Befestigung einer Kette enthält ein U-förmiges Kettenhalbglied (1), dessen Stirnflächen einen Anschlagflansch (3) aufweist, dessen Länge grösser ist als die doppelte Dicke des Bogenteils (2) sowie ein Kreuzstück (8) zur Befestigung des Kettenhalbgliedes mit einer kreuzförmigen Ausnehmung (11), in die das U-förmige Bogenteil (2) des Kettenhalbgliedes wahlweise senkrecht oder waagrecht hindurchgesteckt werden kann, um es in dieser Stellung an eine Wand, an einen Pfahl oder dergleichen zu befestigen. Der komplette Bausatz enthält ferner ein zweiteiliges Joch, um die Glieder miteinander zu verbinden und ein Wendestück, um die Gliederhälften um 90 o verdreht miteinander zu verbinden. Ein solcher Bausatz ermöglicht die problemlose Befestigung und rationelle Herstellung von Ketten und gewährleistet eine ästhetisch einwandfreie Durchbiegung und Anordnung der Kette.
