Socket insert for hand tools

The invention relates to a socket insert for hand tools which can connect a ring or open-end wrench with different socket sleeves, whereby the ring or open-end wrench can turn different screws or nuts.

Screws and nuts vary in shape and size. For example, to turn a 24 mm screw, you need a corresponding ring spanner, as each ring spanner is only suitable for a certain size of screw. To turn a screw of a different size, you need a different ring spanner. To turn screws of different sizes, you therefore need to get different spanners.

The invention is based on the task of creating a socket insert for hand tools which can connect a ring or open-end wrench with different socket sleeves, whereby the ring or open-end wrench can turn different screws or nuts.

This object is achieved according to the invention in that the socket insert has a polygonal body in the middle which can be enclosed by a ring or open-end wrench and on the top and bottom of which a square is provided which can be inserted into a socket sleeve in order to turn a screw or nut.

In the following, the invention is explained in more detail with reference to the accompanying drawings:

Referring to Figure 1, the plug insert (1) according to the invention serves to connect a ring and open-end wrench (40) to a plug sleeve (20), characterized in that

the socket insert (1) has a polygonal body (10) in the middle which can be enclosed by the ring and open-end wrench (40) and whose top and bottom each have a square (11), (12) which can be inserted into the socket sleeve (20) in order to turn a screw or nut (30).

As can be seen from Figures 2 and 3, the socket insert (1) is enclosed by the ring and open-end wrench (40) and the polygon (11) of the socket insert (1) is inserted into the socket sleeve (20). The socket sleeve (20) can then be pushed over a screw or nut (30) in order to turn it. Only one ring and open-end wrench (40) is required for this. Since the socket of the socket sleeve (20) usually has four sizes, the two square edges (11), (12) of the socket insert (1) can have different sizes, whereby the ring and open-end wrench (40) can be connected to all socket sleeves if the ring and open-end wrench (40) is equipped with two socket inserts (1). In this case, a socket wrench is formed by the ring and open-end wrench (40), the socket insert (1) and the socket sleeve (20).

In Figure 4, the polygonal body (10) of the socket insert (1) is enclosed by the fork head of the ring and open-end wrench (40).

As can be seen from Figure 5, the plug insert (1) has two square edges

(11), (12), of which one square (12) can be inserted into a larger socket (20) for turning a larger screw or nut (30) and the other square (11) can be inserted into a smaller socket (20) for turning a smaller screw or nut (30).

The second embodiment of the invention is shown in Figure 6. As shown, the polygonal body (10) of the socket insert (1) is designed as a cylinder with two flat surfaces (101) for the fork head of the ring and open-end wrench (40).

The third embodiment of the invention is shown in Figure 7. As shown, the polygonal body (10) of the socket insert (1) is provided with a through hole (13) for a rotary rod (50), so that the socket insert (1) can be driven by the rotary rod (50) in addition to the ring and open-end wrench (40).

Figures 8, 9, 10 show the fourth, fifth and sixth embodiments of the invention. As shown, the polygonal body (10) of the socket insert (1) is provided with blind holes (102), in each of which a spring element (14) is accommodated in order to prevent the socket insert (1) from coming loose from the ring and open-end wrench (40). Alternatively, the polygonal body (10) can be provided with a circumferential flange (104), (105) on the underside or in the lower area, whereby the same purpose can be achieved.

The seventh embodiment of the invention is shown in Figure 11. As shown, the plug insert (1) is provided at suitable locations with steel balls (103), (111), (121) which have a positioning effect.

Figure 12 shows the eighth embodiment of the invention. As shown, the plug insert (1) is provided with a push button (106). When the push button (106) is pressed, the steel ball (102) returns into the plug insert (1).

Figure 13 shows the ninth embodiment of the invention. As shown, the square (11) of the plug insert (1) is replaced by a plug sleeve (11) with a polygonal recess (112).

-A-

Figure 14 shows the tenth embodiment of the invention. As shown, the square (H) of the plug insert (1) is connected in an articulated manner to another square (113), whereby the plug sleeve (20) can be pivoted.

The eleventh embodiment of the invention is shown in Figure 15. As shown, a ratchet insert (107) is provided between the polygonal body (10) and the two square edges (11) (12), which enables the plug insert (1) to be used on a ratchet wrench.

Figure 16 shows the twelfth embodiment of the invention. As shown, the two square edges (11), (12) of the socket insert (1) are each firmly connected to a socket sleeve (114), (122), whereby the ring and open-end wrench (40) can directly turn a screw or nut.

Figure 17 shows the thirteenth embodiment of the invention. As shown, the polygonal body (10) of the socket insert (1) is provided with a flange (104) at a suitable location, as in Figure 9, whereby the socket insert (1) can be prevented from coming loose from the ring and open-end wrench (40).

Figure 18 shows the fourteenth embodiment of the invention. As shown, a smaller square (15) is provided on the larger square (12), whereby the plug insert (1) has three squares (11), (12) and (15) with three different sizes.
