Device for hanging a so-called fly line

Abstract

Device for suspending a so-called fly-line, i.e. a support tube (31) in particular for tube slides or the like, wherein a hook (1) is provided which engages in the support tube (31).

Description

[0001] The invention relates to a device for suspending a so-called fly-line, i.e. a support tube, in particular for tube slides or the like.

[0002] Support tubes, especially for a fly-line, must be anchored in the air, i.e., suspended. To ensure that the use of the sleds guided by them is not impaired, the suspension must only attach to the top and occupy a very small portion of the circumference. Furthermore, it is important that the joints between individual tubes are as smooth as possible to prevent impacts on the sleds.

[0003] The object of the invention is therefore to propose a device of the type mentioned above which can be used rationally, is very flexible in its arrangement and yet ensures secure anchoring.

[0004] This problem is solved according to the invention by providing a hook that engages in the support tube.

[0005] The hook engages through a slot in the support tube and rests against its inside.

[0006] It has proven very advantageous to have two hooks provided.

[0007] Two cooperating hooks ensure a secure attachment at each suspension point.

[0008] In this context, it is also particularly advantageous if the two hooks are aligned in opposite directions along the longitudinal direction of the support tube.

[0009] The opposing orientation allows for particularly good absorption of longitudinal forces. Furthermore, the device is very well suited for use at the joints of two pipes.

[0010] Furthermore, it has proven particularly advantageous if the hooks are equipped with an opening for receiving a shackle or a screw connection.

[0011] This allows the hooks to be tightened and hung particularly well.

[0012] It has proven to be very advantageous if a crossbar is provided for connecting two hooks, wherein the crossbar has an opening for receiving a shackle or the like and corresponding openings for screwing it to the other and / or the hooks.

[0013] The traverse connects two hooks, usually positioned in opposite directions, creating a common anchor point for guying. The traverse can be an integral part of both hooks. An additional or separate traverse, for example for reinforcement, is also possible.

[0014] Another embodiment of the invention that is very advantageous according to the invention is present when the contact surface of the hook in the support tube is wedge-shaped.

[0015] Due to its wedge-shaped design, which can also act as a cutting edge, the hook digs into the inside of the support tube, thus ensuring an even better hold.

[0016] According to a further very advantageous embodiment of the invention, each hook is designed in such a way that it can be arranged overlapping with another hook.

[0017] This design makes it particularly easy to connect two hooks, for example those arranged in opposite directions, to form a hook arrangement using an integrated crossbar.

[0018] According to a further development of the invention, it is also extremely advantageous if the hooks are able to engage in the support tube, especially from above.

[0019] This results in a very good distribution of the weight forces that occur.

[0020] In this context, it is extremely advantageous if an inner tube is provided in the support tube, into which the hooks can engage.

[0021] Such an inner tube distributes the forces occurring between the hook and the support tube very well.

[0022] It has proven to be very advantageous if the inner pipe is connected to the outer pipe.

[0023] This prevents twisting or slipping out.

[0024] Furthermore, according to the invention, it is very advantageous if the inner tube is arranged at a joint between two outer tube sections to be joined.

[0025] This allows the inner tube to also serve as a connection between two buttressed support tubes. A secure and stable connection is created.

[0026] According to the invention, it is also very advantageous if the outer tube and / or inner tube are at least partially slotted.

[0027] These slots allow hooks to engage and, especially with a slotted inner tube, enable adjustments to be made regarding the diameter. The inner tube then sits flush against the inside of the outer support tube.

[0028] The invention is illustrated below using an exemplary embodiment.

[0029] This shows: Fig. 1 a side view of a hook according to the invention, Fig. 2 a narrow side view of the same hook, Fig. 3 a longitudinal section through a support tube into which two hooks engage and an inner tube is provided, Fig. 4 a cross-section through this support tube, Fig. 5 a longitudinal section through another support tube into which two hooks engage and a short, slotted inner tube is provided, and Fig. 6 a cross-section through this support tube.

[0030] With 1 is in Fig. 1 a hook for hanging a support tube 31 with a hook nose 2 and a hook body 3.

[0031] At the front transition between the hook nose 2 with a contact surface 2a and the hook body 3, an undercut 4 is provided, so that the hook nose 2 with its contact surface 2a can fit neatly against the inside of the support tube 31. At the rear transition between the hook nose 2 and the hook body 3, an undercut 5 is also provided, the contour of which is further rounded. With the hook 1 inserted, the undercut 4 lies inside the support tube, whereas the undercut 5 lies outside the support tube.

[0032] Following the undercut 5, a support surface 6 is provided which is able to rest on the outer surface of the support tube 31.

[0033] Together, these form the lower part 7 of the hook body 3. The upper part 8 of the hook body 3 is attached to this. In this embodiment, the upper part 8 has two bores 9 by means of which the hook body 3 can be screwed to the hook body 3 of another hook 1.

[0034] The upper part 8 is designed in such a way that it forms a bump which can overlap with another hook 1.

[0035] In the upper part of the upper section 8, a further bore 10 is provided, into which a support cable, a shackle or the like can engage. None of this is shown.

[0036] In the present embodiment, the thickness of the upper part 8 is reduced compared to the thickness of the lower part 7 and here amounts to only half the thickness of the lower part 7.

[0037] If two identical hooks 1 are connected to each other in such a way that the two hook lugs 2 point away from each other, a double hook arrangement 32 is created, as shown in Fig. 3 is shown.

[0038] The two lower parts 7 lie next to each other, whereas the two upper parts 8 overlap, thus restoring the full component thickness.

[0039] The bores 9 and 10 are identical. The two hooks are positively connected to each other by means of screws 33 inserted into the bores 9. A shackle or a suspension cable can engage in the bore 10 formed by the two hooks 1.

[0040] The support tube 31 has two slot-shaped recesses 34, each of which can accommodate a hook 1. The width of the recess 34 corresponds to the thickness of the hook 1, and its length is precisely such that the hook nose 2 can be inserted into the recess 34 and tilted in such a way that the contact surface 2a rests on the inside of the support tube 31 and the contact surface 6 rests on the outside of the support tube 31.

[0041] In the Fig. 3 In the illustrated embodiment, an inner tube 35 is arranged in the support tube 31 and is connected to the support tube 31 via connecting elements 36. Screws or rivets, for example, can be used as connecting elements.

[0042] In this case, the inner tube 35 is made of aluminum and has recesses 37 corresponding to the recesses 34. The hooks 1 thus engage not only through the wall of the support tube 31, but also through the wall of the inner tube 35. The contact surface 2a is therefore supported on the inside of the inner tube 35.

[0043] The relative positions of the contact surfaces 2a and 6 are aligned with the thickness of the support tube 31 and, if an inner tube 35 is provided, with the sum of the wall thicknesses of the support tube 31 and the inner tube 35. It is conceivable that one and the same hook 1 could also be used for tubes with thinner wall thicknesses.

[0044] It is also conceivable that the inner tube 35 not only reinforces the support tube 31, which is usually made of stainless steel, in the area of ​​the hook arrangement 32, but also connects two abutting support tube ends.

[0045] However, it is also conceivable, as in Fig. 5 As shown, a shorter inner tube 55 is provided, which in this example is also made of stainless steel. This inner tube 55 is only slightly longer than the hook arrangement 32. The inner tube 55 in turn has recesses 57 that correspond to the recesses 34 of the support tube.

[0046] Connecting elements are not required here. The inner tube 35 is provided with a longitudinal slot 58 on its underside opposite the recesses 57, which serves to compensate for the diameter of the inner tube 55. The inner tube 55 can thus fit precisely against the inside of the support tube 31. This compensation can be spring-loaded.

[0047] In the case of the hook arrangement 32, it is also conceivable that an additional, not shown, crossbar is provided, which is screwed laterally onto the hook arrangement 32 and connects the two hooks 1 forming the hook arrangement.

[0048] The use of an inner tube 35 or 55 effectively prevents deformation of the support tube 31 by the forces introduced into the hook assembly 32. Furthermore, comparatively larger forces can be transmitted. The precisely fitting recesses 34 prevent longitudinal play in the hook assembly 32, thus allowing longitudinal and transverse forces to be transmitted.

[0049] Overall, this design of hook 1 and hook arrangement 32 significantly improves the tensioning of a so-called fly-line and significantly increases the safety reserves.
