Description

[0001] The invention relates to a nut (1) comprising two ends for screwing in eyebolts, wherein the nut (1) has one end for attaching a tool. background

[0002] Eyebolts are an important component in scaffolding construction for securing scaffolding.

[0003] Eyebolts typically consist of a bolt with a thread and a ring eye attached to the bolt. State of the art

[0004] The disadvantages of known devices are the following: To attach eyebolts, you can traditionally put a long rod, e.g. the handle of a hammer, through the eyelet and turn the eyebolt, which is often time-consuming and impractical, as the eyebolt can bend or clinker bricks on facades can be damaged.

[0005] To avoid such disadvantages, you can use a nut, as shown in DE202023105942U1, to screw in the eyelet using a ratchet.

[0006] The socket in DE202023105942U1 includes a slot to accommodate the eyebolt's ring. However, the eyebolt's eyelet can twist in the slot, making it difficult for a worker to place the eyebolt on a dowel.

[0007] Additionally, the eyebolt's eyelet is at risk of falling out of the slot, especially if the slot is older and worn. This can result in an eyebolt installed high up on a building accidentally falling and injuring other workers on lower levels. In particular, the bolt can fall out of the slot if the worker using the socket holds the ratchet with the slot facing down. This is especially critical if the eyebolt falls with the pointed end facing down. Task and solution of the invention

[0008] Object of the invention: The above-mentioned disadvantages of the prior art are to be avoided.

[0009] This object is achieved according to the invention in a nut of the type mentioned at the outset in that the other end of the nut (1) has a substantially flat shape, that the nut (1) has a cavity (16) with a lateral recess (4, 5, 6) for inserting the eyelet of an eyebolt, and at least one magnet in the side walls of the cavity (16). Advantages of the invention

[0010] Among other things, the following benefits are achieved: The new nut (1) prevents the eyebolt from falling out of the nut (1) so easily.

[0011] These advantages are achieved by a nut (1) having a cavity (16) with a lateral recess (4, 5, 6) for inserting the eyelet of an eyebolt, as well as at least one magnet in the side walls of the cavity (16). The eyelet is held in the nut (1) by the magnet(s).

[0012] Some holes, e.g., four holes (7, 8, 10, 11), can be used to insert the magnets. The magnets then sit in these holes (7, 8, 10, 11) and hold the eyelet in the nut (1) during use.

[0013] It is particularly important that the eyebolt is held magnetically in the recess so that the eyelet does not slip during rotation.

[0014] In developing the invention, the inventor has overcome the following technical difficulties in a non-obvious manner.

[0015] The challenge with the invention was to construct a socket so that the eyelet couldn't rotate sideways or easily fall out of the socket (1). It was also important that a worker could quickly connect the eyebolt to the socket (1). This problem was solved by the socket (1) according to the invention.

[0016] Advantageous embodiments of the invention are set out in the subclaims.

[0017] It is proposed that - that the nut (1) has a guide (9) for inserting the bolt of an eyebolt, - that the lower part of the cavity is designed as a pocket (17) and - that the magnets are mounted in holes (7, 8, 10, 11) in the side walls and are flush with the side walls. Example

[0018] An exemplary embodiment of the invention is described in more detail below with reference to the drawings. In all drawings, the same reference numerals have the same meaning and are therefore explained only once if necessary.

[0019] It shows Fig. 1 the front of a nut (1) according to the invention, Fig. 2 the back of a nut according to the invention (1), Fig. 3 a cross section CC of the nut (1) according to Fig. 4 looking towards the lower part (15), Fig. 4 a longitudinal section AA according to Fig. 6 the front of the nut (1), Fig. 5 a view B according to Fig. 8 from below onto the nut (1) looking towards the upper part (13, 14), Fig. 6 a side view of the nut (1), Fig. 7 a view of the top of the nut (1) and Fig. 8 another view of the top of the nut (1). Structure of the nut according to the invention

[0020] The nut (1) comprises a lower part (15), a middle part (14) and an upper part, which in turn comprises two parts (13, 14). Furthermore, the nut has a circular recess (4, 5, 6) into which the eyelet of an eyebolt can be placed. The recess comprises a lower part (4) and two upper parts (5, 6). It forms a cavity (16) in the nut (1) which has side walls. The nut (1) also has at least one magnet. When the eyelet is inserted, the eyebolt is held in the nut (1) by the magnet(s) so that it cannot fall out again on its own.

[0021] Optionally, the side walls of the cavity (16) can have holes. The magnets can be inserted through or into these holes.

[0022] A guide (9) can be located between the two upper halves (5, 6) of the nut. The bolt of the eyebolt runs through this guide (9) when its eyelet is inserted in the circular recess (4, 5, 6). Two walls, one to the left and one to the right along the guide (9), are designed so that the bolt rests closely against the walls when the eyebolt is inserted. This holds the bolt even more securely and, in particular, prevents it from slipping due to potential rotational movements of the eyelet in the circular recess. The worker can therefore precisely place the eyebolt onto a dowel on a house wall without the screw accidentally slipping and touching the house wall.

[0023] The lower part (12) of the nut (1) can also have holes (10, 11) for magnets.

[0024] The lower part (12) of the socket (1) has a special end so that a worker can attach a tool there to screw the eyebolt into or out of a house wall. This end can, in particular, be a ratchet-shaped end (3) and / or one with an external hexagon shape (2). This makes the socket usable with a variety of tools. A ratchet is typically used as the tool. Operation of the nut according to the invention

[0025] The operation of the nut according to the invention is explained in detail below: Step 1: A worker places the eyebolt into the nut by placing the eye of the eyebolt into the circular recess (4, 5, 6) and inserting the bolt into the guide (9) from above. Step 2: If the nut (1) does not have holes for magnets, it already holds the eyebolt with built-in magnets. If the nut (1) has at least one hole for magnets, the worker places at least one magnet or several magnets in a hole or in the holes (7, 8, 10, 11) of the nut (1). Step 3: Thanks to the magnet(s), the eyebolt can no longer fall out of the socket (1). The worker now connects a ratchet to the ratchet-side end (3) of the socket. Step 3: The worker attaches the eyebolt to the anchor of a house wall and screws the eyebolt into the house wall. Step 4: The worker removes the magnets from the holes (7, 8, 10, 11) if the nut (1) has one or more holes for magnets. If the nut (1) does not have such holes, this step can be skipped. Step 5: The worker removes the nut (1) from the eyebolt. Step 6: When unscrewing the eyebolt, the worker repeats steps 1-5, with the difference that in step 3 he does not have to dock the screw onto a dowel and screws it out of the dowel instead of into it.

[0026] The recess (4, 5, 6) is essentially circular.

[0027] To achieve good operating results, we recommend that the socket (1) be made entirely of steel. This reduces the risk of the socket (1) breaking off when turning the eyebolt.

[0028] The lower part (15) may have a pocket (17). This can ensure that the eyebolt fits particularly well in the lower part (4) of the recess (4, 5, 6) and further improves the hold of the eyebolt in the recess (4, 5, 6).

[0029] The magnets in the holes (7, 8, 10, 11) can be selected so that they do not protrude from the holes, but are flush with the side walls of the cavity (16). This can prevent any complications when inserting the eyebolt. To achieve this, ensure that the thickness of the magnets is not greater than the thickness of the left (13) or right upper part (14) or lower part (15) of the nut (1).
