The transport element 2 is along a longitudinal axis 7 of the basic body 3 arranged, which is also the longitudinal axis of the receiving device 4 is and at right angles to a conveying direction 8th stands. When horizontal conveying direction is the longitudinal axis 7 vertical and is the vertical axis.

The main body 3 has a substantially cylindrical peripheral surface 9 on, but in the conveying direction 8th seen a front and rear contact surface 10 . 11 is provided, as a flattening of the peripheral surface 9 is trained. The distance between the opposite stop surfaces 10 . 11 is dimensioned such that the minimum distance required for the piece of goods to be transported is provided. The contact surfaces 10 . 11 extend over an angular range α of 40 ° to 100 ° relative to the circumference of the body.

To the main body from the conveying direction 8th swing out is in the support element 2 one joint 12 provided so that the main body 3 with the piece goods carrier located thereon 5 around a hinge axis 13 parallel to the conveying direction 8th is, can be pivoted. This may be important in order to reduce transverse forces acting on the transport device, not shown.

In the 2A B is a second intermediate hook according to the invention 21 shown at the base body 3 two carrier elements 22 . 23 are provided, in turn, on top of the main body 3 are arranged. On the bottom of the main body 3 is located as already in 1 the receiving device 4 for a piece goods carrier 5 ,

The two support elements 22 . 23 extend parallel to the longitudinal axis 7 of the basic body 3 from the top of the main body 3 away and are in the conveying direction 8th seen in front of and behind the longitudinal axis 7 arranged and lie approximately in an imaginary center of the contact surfaces 10 and 11 , Between the two support elements 22 . 23 is in the body 3 an opening 24 provided that an economical use of material even with larger, outer dimensions of the body 3 allows.

It can be seen that the peripheral surface 9 is substantially cylindrical, that is at a predetermined curvature substantially parallel to the longitudinal axis 7 runs. Also the contact surfaces 10 . 11 are parallel to the longitudinal axis 7 aligned, but without curvature. The straight version of the peripheral surface 9 when tilted causes the peripheral surface 9 forms a slip slope, which has a self-centering of adjacent intermediate hook after a curve or in a jam track result, see later 5A . 5B , In the main body 3 are breakthroughs 25 . 26 for the support elements, not shown 22 . 23 provided in the area of the openings 25 . 26 also, can be rotatably mounted.

In the main body 3 Additional weights can be provided to improve a down rolling on a sliding bevel when only very light cargo to be transported. Also in the carrier elements 22 . 23 a joint can be provided which allows a movement transversely to the conveying direction. In the conveying direction, however, no movement except a game is possible.

Another embodiment of an intermediate hook 31 is in 3 shown. The intermediate hook 31 has three transport elements 32 on, extending over the top of the main body 31 extend. The main body 3 is designed in several parts and has a in the conveying direction 8th seen in front lying front part 35 and seen in the conveying direction behind the rear part 36 on. By the division of the main body 3 in a front part 35 and in a rump 36 a cornering of the intermediate hook can be made possible because the front part 35 and the rump 36 via an unillustrated hinge with each other about the longitudinal axis 7 are rotatable. This is the middle support element 33 on the longitudinal axis 7 , as well as the pivot point of the swivel joint. In the present embodiment, two support elements are arranged on the rear part, on the front part 35 a carrier element 32 , In addition, it is on the front 35 also the recording device 4 arranged so that at one in the eyelet 4 hinged transport goods themselves the front part 35 with the first carrier element 32 twisting towards the rest. A twist angle is here in the range of 15 to 75 °, preferably 20 to 50 °.

In the two-part body 3 is the front contact surface 10 on the front part 35 and the rear contact surface 11 at the rump 36 , Both the front part 35 as well as the rump 36 have a curved peripheral surface 9 . 9 ' parallel to the longitudinal axis 7 runs and in the case of a per se undesirable deflection of the intermediate hook transverse to the conveying direction 8th Sliding slopes for self-centering under the influence of the applied gravity leads.

The rump 36 has a front part 35 facing, outwardly curved peripheral surface 37 in their radius of curvature of an inwardly curved peripheral surface 38 on the front part 35 equivalent. In addition, the front part lie 35 and the rump 36 in the area of the rotary joint on each other, so that a mutual support along the longitudinal axis 7 he follows.

In the illustrated embodiment, the eyelet 4 on the front part 35 arranged as the front part 35 the rump 36 from below to at least to the rotary joint over, as in 3B shown. There is also recognizable that the pivot bearing from the support element 33 may be formed by an opening 39 in the rump 36 and through an opening 50 in the front part 35 , which are arranged one above the other in the direction of the longitudinal axis, is inserted and that via a security element 51 can be secured. To transfer power into the eyelet 4 hinged transported goods, it may be useful, too at the top of the opening 39 a fuse 52 be provided so that at the eyelet 4 attacking load case all three support elements are charged.

In 4A is an inclined conveyance of a cargo using an intermediate hook 2A , B shown.

This is one in the conveying direction 8th sloping conveyor track 41 used on the several intermediate hooks with their basic bodies 3.1 to 3.3 by means of their respective carrier elements 22 . 23 are guided. The leadership of the support elements is carried out so that a lifting of the support element 22 . 23 from the conveyor belt 41 avoided, for example, by providence of an upper leadership 42 , see also 5b for a transport roller according to the EP 1 013 569 A1 ,

By this type of leadership of the support elements 22 . 23 is also the body 3.1 to 3.3 essentially parallel to the conveyor track 41 , wherein the mutually adjacent basic body 3.1 to 3.3 at the contact surfaces 10 respectively 11 abut each other.

The cargo is above the cargo carrier 5 into the eye 4 hung on the underside of the body and the cargo is, according to gravity, at an angle to the longitudinal axis 7 of the intermediate hook 21 ,

In 4B an inclined conveyor is shown, in which the intermediate hooks are conveyed upwards. These are with the support elements 22 . 23 cooperating drive means 40 provided, which may for example be attached to a driven chain, not shown. Unlike in 4A there is a distance between the basic bodies 3.1 . 3.2 ,

5A is a schematic representation of the main body 3.4 to 3.4 a series of intermediate hooks in a view from above, wherein a basic body 3.6 transverse to the conveying direction 8th is offset. The basic body 3.4 to 3.7 the intermediate hooks are about their respective support elements 22 . 23 with the conveyor belt 41 connected, optionally with the interposition of a transport roller, as in 5b indicated.

It is immediately understandable that the intermediate hook with the main body 3.6 Because of the inclination relative to the vertical due to the influence of gravity, a force on the adjacent body 3.5 . 3.7 exerts, wherein the main body along the curved peripheral surface 9 slide along each other. In particular, in a downgrade of the system then pushes the body 3.6 between the main body 3.5 and 3.7 so that these again at the contact surfaces 10 . 11 abut each other. The peripheral surface 9 can also be slightly convex or become a piece goods carrier 5 be tapered, indicated by the dashed line.

In 5b this is again clarified. Starting from the body swung out of the row 3.6 with that in his eyelet 4 taken up piece goods carrier 5 becomes a restoring force in the direction of the arrow 43 provided over the peripheral surface 9 acts on the respective body on this. Because of the curvature of the peripheral surface 9 pushes the deflected body 3.6 back to the row.

The intermediate hook is in the embodiment shown via a transport element 44 formed as a transport roller according to the EP 1 013 569 A1 on the guideway 41 stored, wherein the transport element 44 from the leadership 42 at the jump off the conveyor track 41 is not changed. Thus, the in 4 shown inclined conveyance possible.

In 6 is the behavior of several intermediate hooks in a curved conveyor track 41 shown in a view from above. It can be seen that the basic body in the region of the curvature of the conveyor track 41 only abut each other at a lateral edge of the contact surfaces. Even in this situation, gravity ensures that a largely vertical alignment of the intermediate hook is maintained.

In 7 is the cornering of the intermediate hook off 3A shown schematically. Due to the swivel joint 71 of the intermediate hook 31.1 to 31.3 can adjust the front part relative to the rear part, so that despite the configuration with three support elements per intermediate hook cornering along the guideway 41 is possible.
