Foldable tripod mounting aid for fixing supports with sensitive surfaces

Abstract

Foldable tripod assembly aid for fixing the position of supports of various geometries and cross-sections with sensitive surfaces, as well as the possibility of alignment in four axes, characterized in that supports (14) are fixed securely and non-slip in a belt tensioning prism (5) (6) (7), which is part of a foldable, screwed together, tripod tubular frame welded construction (1) with continuously telescopic and lockable legs (2) (3).

Description

Main claim:

[0001] Foldable tripod mounting aid ( Fig. 5) ( Fig. 6) for tool-free positional fixation of supports (14) of various geometries and cross-sections with sensitive surfaces, as an aid for erecting fully or partially free-standing structures, combined with the option of precisely aligning the supports in four axes. Characterized in that supports (14) can be securely and non-slip fixed in a belt tensioning prism. The belt tensioning prism consists of a V-shaped prism (5) with non-slip contact surfaces (6), into which the support (14) is pressed with the aid of the belt strap of an automatic ratchet tensioning belt (7) and thus securely fixed. The tensioning mechanism is part of a foldable tripod tubular frame welded construction (1) with continuously telescopic and lockable legs (2) (3). Description:

[0002] In order to erect completely or partially free-standing structures such as attached balconies, exhibition stands, storage platforms, patio roofs, louvre roofs or pergola awnings, supports must first be placed, to the upper end of which crossbeams, connecting profiles, guide rails or rafters are then attached.

[0003] Until now, it has been common practice to temporarily secure these supports with the help of additional personnel or makeshift support structures until a self-supporting structure is achieved. The exact requirements for this must always be adapted to the local conditions, as substrates and any constraints vary depending on the application. Reliable protection, especially for coated surfaces, can hardly be guaranteed when securing them with battens or screw clamps. While surface damage can be effectively avoided by people "holding" the supports, this poses a significant risk of injury due to fatigue and toppling or falling components.

[0004] A sufficiently durable fastening to the substructure, for example, with screws, is often disadvantageous, as it is no longer possible to later align the finished structure with millimeter precision to meet required tolerances. This would also preclude subsequent repositioning using a crane.

[0005] The invention specified in claim 1 is based on the problem of erecting a completely or partially free-standing construction made of coated steel, aluminum or wood components with little personnel and equipment expenditure, in a time-saving and safe manner, in order to then align it precisely and only later to be able to fasten it in its final position.

[0006] Case study: A freestanding patio roof made of powder-coated aluminum profiles on four supports is to be erected, aligned, and secured on a load-bearing base plate by two people.

[0007] With the help of the invention (four required), the four supports can first be carefully set up freestanding in the belt tensioning prism (5) (6) (7). To do this, the individual supports (14) are leaned against the designated contact surfaces (6) of the tensioning prism (5). The belt is then pulled out of the ratchet tensioning belt with automatic retraction (7) to the required length in order to guide the support (14) to be tensioned, and is hooked into the designated attachment eyelet (10) using the safety carabiner (8) at the end of the belt. The belt is then tightened using a "ratchet" (7), and the support is thereby pressed into the prism (5) with its non-slip contact surface (6). The support can now be aligned as required using the continuously telescopic legs (2). The telescopic legs (2) are then securely locked using wing screws (3) to prevent later changes in position.The swivel stop (11) on the legs immediately left and right of the clamped support (14) reliably prevents the legs from colliding with the coated support (14) in the event of incorrect operation. Abrasion or abrasion marks caused by the strap are reliably avoided by a special strap pad (9) that surrounds the strap. After approximately positioning the supports on the base plate, the two people can attach all connecting cross members, rafters, etc. to the upper end of the supports. Once the structure is self-supporting and bolted together, the invention can be removed again after loosening the straps. All work steps related to the invention are carried out without tools. In the final steps, the distances and diagonals between the supports can be slightly adjusted if necessary in order to then anchor the structure once and for all in its final position on the base plate.

Claims

[1] Foldable tripod mounting aid for fixing the position of supports of various geometries and cross-sections with sensitive surfaces, as well as the possibility of alignment in four axes, characterized by that supports (14) are fixed securely and non-slip in a belt tensioning prism (5) (6) (7), which is part of a foldable, bolted together, tripod tubular frame welded construction (1) with continuously telescopic and lockable legs (2) (3). [2] Assembly aid according to claim 1, characterized by The belt tensioning system uses an automatic ratchet tensioning belt (7) to adjust the tensioning force depending on the requirements or sensitivity of the support to be tensioned. For additional surface protection, the belt is partially padded with a special belt pad (9), ensuring that no chafing or abrasion marks occur on the support (14) during the tensioning process. [3] Assembly aid according to claim 1, characterized bythat the three support legs (2) are individually telescopic and can be continuously locked using wing screws (3) to enable exact alignment of the support (14), even when clamped or on uneven ground. [4] Assembly aid according to claim 1, characterized by that all three legs can be folded almost independently of each other ( Fig. 5) ( Fig. 6) to enable the fixing of supports (14) in confined positions such as niches or directly in front of walls. [5] Assembly aid according to claim 1, characterized by that lighter supports (14) can be clamped in a freely suspended position without having to stand on the mounting surface, in order to be able to subsequently fix them at the correct level or, for example, to be concreted in. [6] Assembly aid according to claim 1, characterized by that assembly and disassembly, as well as the use of all individual functions, is possible without tools. [7] Assembly aid according to claim 1, characterized by that the pivoting range of the two legs immediately to the right and left of the clamped support is limited by a stop (11) in order to reliably prevent the legs from colliding with the support (14) in the event of incorrect operation.
