/ mils like fastening device

description

The proper attachment of objects to walls Masonry or anything else, or devices that are used to hang up more or less heavy objects, happens mostly by hammering in hooks and the like or plastering the fasteners Presence of light building materials such as For example, pumice stones and the like, or significant for ceiling mountings Difficulties that have a loose fit of the aforementioned fastenings result and sometimes serious accidents especially when attaching small objects.

The innovation is based on the task of eliminating this disadvantage. This is done according to the invention in that a sleeve-like fastening device, preferably from made of a hard material, consisting of a round or square sleeve (1) which is expediently with a Tip (2) or the like. Is hammered into a hole pre-drilled according to the diameter. This is the rear end of the sleeve (1) is provided with a corresponding attachment ring (13) attached to the inside or outside of the under The use of a driver enables the sleeve to be hammered into walls and the like of any kind without damage.

The sleeve (1) also serves to accommodate the loose expansion parts (7) shown, for example, or the supported ones Spreading parts (8) which are driven outwards by a screw-in part (4) (9). This ensures that the Press expansion parts outwards into the masonry or the like and there barbs bi the, an unconditional pests sit the sleeve-like fastening device against tensile forces guarantee.

The sleeve (1) is preferably metric for receiving the screw-in part (4) (9), for example with an internal thread (3) ISO thread provided, whereas the screw-in parts (4) (9) are provided with external thread (5) (11).

Claims (7)

In order to push the expansion parts apart, the front end of the screw-in parts (4) (9) is expediently provided with a conical or conical tip (14). The screw-in part (4) is also used to suspend or fasten objects and is expedient to a hook, preferably in a curved arc (15) or, for example, to a hammer (16) or the like. educated. The appropriately designed expansion parts (8) are supported by a bolt (9). It is thereby achieved that the expansion parts anchor themselves with increased force in the surrounding material. Especially heavy-duty fastenings had to be appropriate solution can be found. For this purpose, several expansion parts (8) are first attached in pairs with bolts (9). Preferably four supported spreading parts (8) are used. Furthermore, the higher attack forces require the use of a special inner bolt (10) which is expediently provided with an external thread (11), which fits to the inner thread (3) of the sleeve (1). The inner bolt (10) has at its front end a preferably square or SecJaskant key surface (17) »for more powerful insert into the sleeve (1), as well as an internal thread (12), for receiving the actual assembly elements, for example hooks (18) or eyes (19) · Preferably however, commercially available machine screws and the like are used to attach mounting brackets, cabinets, etc. The innovation is explained using the drawings, for example: The top row shows the sleeve (1) in different Aus = - management forms with the spreading parts shown, for example (7) (8). In the middle row, some versions of the screw-in part (4) and the inner bolt (10) are shown. The bottom row of the embodiments shown, for example, shows representations in top view. Protection claims. 1 sleeve-like fastening device characterized that a sleeve (1), preferably made of impact-resistant material, on the insertion side to a tip (2) or otherwise appropriately shaped, provided with an internal thread (3), on the rear part an internal or external attachment ^ ring (13) has the ability to drive the sleeve into pre-drilled holes in materials of any kind without damage and by screwing in a screw-in part (4) or an inner bolt (10) its loose or stored Movable movable equal or unequal-sided spreading parts (7) (8) pushes outwards as a barb. 2. Apparatus according to claim 1, characterized in that the screw-in part (4) with external thread (5) at the same time for hanging objects, preferably as a hook (6) Eyes or hammer (16) is formed. 3. Apparatus according to claim 1 and 2, characterized in that the expanding parts (4) are loosely attached in the sleeve (1) and when the screw-in part (4) or inner bolt (10) is screwed in, it pushes itself outwards as a barb. 4. Apparatus according to claim 1 and 2, characterized in that the equilateral or unequal-legged expansion parts (8) are mounted with bolts (9) in such a way that they act as barbs when the screw-in part (4) or the inner bolt (10) is screwed in push outwards. 5. Apparatus according to claim 1 to 4, characterized in that the expanding parts (7) (8) preferably in pairs or also are attached several times in longitudinal slots of the sleeve (1) in one or more planes. 6. Apparatus according to claim 1 and 3 to 5, characterized in that, the Inarenbolzen (10) with external thread (11) at its front end with a key surface (17) and a Internal thread (12) for receiving hooks (18) eyes (19) preferably commercially available screws and fasteners is provided. 7. Apparatus according to claim 1 to 7, characterized in that the inner bolt (10) or the screw-in parts (4) in Your front part for driving apart the expansion parts (7) (8) preferably with a conical, spherical or conical tip ^ are provided.
