Definitions
- Hook for attaching a sling chain to a container
- the invention relates to a hook for attaching a chain sling to a container or the like with at least one hook nose arranged at the end of a pivot pin and oriented perpendicular to the axis of the pivot pin, which can be inserted into a receptacle on the container with an elongated hole-like opening , in which it is held after rotation from the insertion position by reaching behind a wall section of the receptacle, and with a securing device which counteracts unwanted unhooking of the hook nose from the receptacle.
- a hook of the type under consideration is known, the securing of which consists of a pivotally mounted angle lever which, after the insertion of two hook lugs forming a hammer head into the receptacle of the container, preferably under the action of a spring force with its free end snaps into the opening of the receptacle after it has previously been held in an inactive position by the person handling the hook, into which it must be pivoted back when the hook is removed from its receptacle. Since the free end of the angle lever protrudes from the outside into the opening in the receptacle, it limits the degree of pivoting of the hook.
- the invention has for its object to design a hook of the type under consideration so that it can be handled comfortably with one hand.
- the securing means consists of a locking bolt which is guided in a first bore of the hook which is arranged in the region of the end of the pivot which merges with the hook lug and a locking bolt which runs through the pivot in a first hole which cuts through the pivot.
- the hook according to the invention has the advantage that when the hook nose is inserted into the receptacle of the container, the locking pin can be easily moved into its securing position and when the hook is released, only a pressure has to be exerted on the free end of the actuating pin. Since the locking pin engages behind the insertion opening, the hook can be rotated by 180 ° without the risk of damaging the fuse.
- FIG. 1 is a side view of a container hook, which is provided with a safeguard against unwanted unhooking from a container fitting,
- Fig. 11 is an inside view of a fitting of a container
- FIG. 12 shows a section along the line XI-XI in FIG. 10.
- 1 is the main part of a hook which can be picked up by a user and which is provided with a fork head 3 having a connecting bolt 2 for a chain sling (not shown) or a lifting rope.
- a pivot pin 4 adjoins the main part 1 of the hook and merges into a hook nose 5 at its free end.
- two hooked lugs arranged like a hammer head can also be used.
- a bore 6 extending through the main part 1 and the pivot pin 4 of the hook extends into the area of the hook nose 5, the longitudinal axis 7 of which is perpendicular to the longitudinal axis 8 of a further bore 9 and which extends almost over the entire width b of the pivot pin 4 or the hook nose 5 extends.
- An actuating bolt 10 is mounted in the bore 6, with the aid of which a locking bolt 11 guided in the bore 9 can be pressed against the action of a spring 12 from a locking position shown in FIGS. 2, 3 and 8 into the release position shown in FIG. 9 is.
- the actuating pin 10 has at its free end an inclined surface 13 to which a locking cam 14 connects, which engages behind the locking pin 11 in the assembled state of the actuating pin 10 and in this way the cohesion of actuating pins 10 and locking pin 11 guaranteed.
- a locking cam 14 connects
- the inclined surface 17 of the locking bolt 11 has an angle ⁇ of approximately 50 ° with the longitudinal axis 8 of the locking bolt 11, while the angle ⁇ between the
- Inclined surface 13 of the actuating bolt 10 and its longitudinal axis 7 is approximately 40 °.
- the locking pin 11 is equipped with a further inclined surface 18 which makes an angle ⁇ of approximately 60 ° with respect to the longitudinal axis 8 of the locking pin 11.
- the inclined surface 18 and the type of assignment of the actuating pin 10 to the locking pin 11 becomes automatic when the hook nose 5 is inserted into an opening 19 of a fitting 20 arranged on the container and adapted to the shape of the hook nose 5 through one of the longitudinal edges 21 or 22 of the opening 19 transferred to the position shown in Figure 9.
- the end of the locking pin 11 is moved back into the position shown in FIG. 8 by the spring 12, so that the hook nose 5 is held securely in the fitting 20.
- the locking pin 11 is provided with an insertion groove 24 which the locking cam 14 can pass if the locking pin 11 with a force P in, for example with the aid of a pencil or dome Direction of arrow 25 is pressed against the action of spring 12 in the position shown in Figure 10.
- a vent hole 26 connects to the end of the hole 9.
- the longitudinal axis 27 of the hook nose 5 can assume inclined positions which cannot be realized in the known construction described at the beginning.
