Description

Connection of crossing tubes or rods with a safety hook The invention is based on a connection of intersecting tubes or rods a safety hook with the largest possible opening, the safety hook is firmly connected to the one to be connected part in the longitudinal direction and the other part to be connected its hook part at an angle of more than 180 °, wherein one leg of the hook is also a spring-loaded, in hook closure or opening position is movable closing part, furthermore the hook on his The end has a tangential extension which is approximately at right angles to the approach direction of the hook runs on the part to be connected.

In the case of connections of the type just mentioned, a locking part is used spring loaded bolt provided. In this known construction is not with great security achieved that the hook does not move from the part to be connected solves when corresponding forces occur directed against the opening of the hook mouth. Also, with this known connection, the assembly is not easy by simple Pressing the hook onto the rod-like part to be connected is possible.

It has also become known a hook construction in which the Closing part is guided in a slot of the hook and by pivoting in the closed position can be brought.

Finally, a hook has also become known in which the locking part by a leaf spring attached to the outer circumference of the hook in the closed position is pressable.

The object of the invention is towards this known person is Connections of the type mentioned in the first paragraph of this description improve that with easy assembly a secure attachment as possible against occurring in all directions, acting on the parts to be connected Forces is reached.

To solve this problem, the details are largely known Design features provided, which consist in the fact that the locking part in one Slot of the hook is hinged at a point farther from the attachment point of the hook on the one part to be connected lies than the free end of the locking part on the hook in its closed position, the circular shape of the hook continues, the Closing part around its articulation on the hook against the one-sided attached to the circumference of the hook to the articulation extending leaf spring from the rod or the pipe can be pivoted away.

The invention achieves ao in a simple manner that with simpler Mounting as secure a fastening as possible against the in all directions to the forces to be connected is reached. Due to the special nature and position of the articulation point and the type of articulation of the locking part and its Shape and position is achieved in the invention that forces that, for. B. opposite of the hook bracket occur, do not open the hook mouth, but even to contribute tighter closing. In addition, this type of locking part design achieved that when the hook is placed on the part to be connected, the hook mouth opens easily and when the connection is complete, under the pressure of the leaf spring easily closes again.

The invention is illustrated using an exemplary embodiment in the drawing explained in more detail. Here, FIG. 1 the hook on the one part to be connected seen from the side and F i g. 2 is a view of the representation as it is after F i g. 1 is listed.

From the drawing is the connection of intersecting tubes or rods with a safety hook 1 with the largest possible mouth width, the safety hook 1 is firmly connected to the one to be connected part 7 in the longitudinal direction and the other part to be connected with its hook part at an angle of more as 180 ° to recognize. One leg of the hook l is a spring-loaded, Closing part 2 movable in hook closing or opening position. The hook 1 has at its end a tangential extension 6 which is approximately at right angles to the approach direction of the hook 1 runs on the part to be connected. The closing part 2 is in one Slot 5 of the hook 1 hinged at a point 3, which is further from the attachment point of the hook 1 on the part 7 to be connected lies as the free end of the locking part 2, the circular shape of the hook 1 continues on the hook 1 in its closed position, wherein the locking part 2 around its articulation 3 on the hook 1 against the one-sided attached, leaf spring 4 extending around the circumference of the hook 1 to over the articulation 3 can be pivoted away from the rod or the tube.

Claims (1)

Claim: Connection of crossing pipes or rods with a safety hook with the largest possible mouth width, the safety hook being firmly connected to the one part to be connected in its longitudinal direction and the other part to be connected with its hook part at an angle of more than 180 °, wherein one leg of the hook is a spring-loaded locking part that can be moved into the hook closing or opening position, the hook also having a tangential extension at its end which runs approximately at right angles to the attachment direction of the hook on the part to be connected, characterized by the Combination of the largely known design features, which consist in the fact that the locking part (2) is hinged in a slot (5) of the hook (1) at a point (3) which is further from the fastening point of the hook to the one to be connected Part (7) is the free end of the locking part, on the hook in its locking position ung the circular shape of the hook continues, whereby the locking part can be pivoted away from the rod or the tube about its articulation (3) on the hook against the leaf spring (4) which is attached on one side and extends around the circumference of the hook to beyond the articulation.
