Abstract

A socket for use with a ratchet wrench includes a front segment 12 and a rear segment 11. The front segment 12 has an axially extending bore shaped to fit snugly over the head of a threaded fastener in order to turn the fastener. The rear segment 11 adjacent to the front segment is adapted to be rotated by the pin of a ratchet wrench. The outer lateral wall of the front segment 12 has at least two flat surfaces 122 which are diametrically opposed to each other in order that the socket may also be rotated by an open-ended spanner 30. <IMAGE>

Description

- - 1,1 1 ---J --1-- A SOCKET FOR USE WITH A RATCHET WRENCH The present

invention relates to a novel socket for use with a ratchet wrench, and more particularly to a socket with a novel shape which makes it more useful than conventional socket.

Referring to Fig.1, the conventional socket (1) for use with a ratchet wrench includes a front segment (3) and a rear segment (2). Said front segment (3) has an hexagonal axially extended bore to fit snugly over the head of a threaded fastener. Said rear segment (2) adjacent to said front segment (3) is adapted to be rotated by the pin of ratchet wrench (not shown). This configuration has many disadvantages. For example, provided a mechanic intended to use said socket to turn a bolt, it is difficult for him to use said socket to rotate the top end of a bolt by hand. He must ratchet wrench, because the lateral wall conventional socket is rounded and use the of a smooth and the mechanic often has greasy hands while at work. If thi.s socket is accidentally dropped, it can very easily roll out of reach as a result of its cylinder-like figure. Supposed a work several sizes of only the one configuration is necessary to rotate nuts one person can work on such things at one novel socket is characterized by the outer team uses a ratchet set(l wrench, sockets). Problems arise because with wrench, which in the conventional or bolts,only time. The lateral wall --2-- of said front segment having at least two flat surfaces which are opposite to each other. The purpose of the present invention is to overcome the drawbacks of the prior art.

The object of the present invention is to provide a novel socket which is adapted for rotation by a ratchet wrench or other types of wrench (such as crescent or monkey wrenches), or by hand.

According to this invention, a socket for use with a ratchet wrench includes a front segment and a rear segment,said bore shaped fastener in segment is adapted to the outer least two front segment having an axially extended to fit snugly over the head of a threaded order to turn said fastener; said rear adjacent to said front segment and is be rotated by the pin of a ratchet wrench; lateral wall of said front segment has at flat surfaces which are opposed to each other.

Other features and advantages of the preferred embodiment of the invention will become clear as the invention is described in detail with reference to the following drawings, of which:

Fig. 1 is a perspective view of a socket to the prior art;

Fig. 2 is a embodiment of a sockQt invention; 1 i i according perspective view of a preferred according to the present i i 1 1 1 i 1 1 i 1 1 --3-Fig. 3 depicts a preferred embodiment as it is intended to engage the ratchet wrench according to the present invention; Fig. 4 depicts a preferred embodiment as it is intended to engage a crescent wrench according to the present invention; Referring to Fig. 2, a novel socket/for use with a ratchet wrench includes a front segment (12) having an axially extended bore which is shaped to fit snugly over a nut or the top end of a bolt, a rear segment (11) adjacent to said front segment and adapted to be rotated by the pin of a ratchet wrench. The bore (120) in said front segment (12) is hexagonal and extended axially, this configuration being the same as the prior art. The outer lateral wall qf said front segment is formed by multiple pairs of flat surfaces (122) adjacent to axial recesses (121). The flat surfaces of each pair are diametrically opposite to each other. Each recess (121) is interposed between two successive flat surfaces (122) so that the recesses alternate with the flat surfaces. The corners (1201) of said hexagonal axially extended bore (120) correspond to the locations of said flat surfaces (122) in order to increase the thickness of said outer lateral wall, reinforcing the socket structure. The sides (12011) of said hexagonal axially extended bore correspond to the locations of said recess (121). The free periphery of said front --4-- a segment (12) inclines outwardly and downwardly to form a sloped surface (130), in order to dulled the edge between the flat surfaces (122) and recesses (121).

Referring to Fig. 3, a novel socket (10) is intended to engage the ratchet wrench, where the method of assembly is the same as the prior art.

Referring to Fig. 4, each pair of the flat surfaces (122) of novel socket /can be engaged and rotated by a crescent wrench (30) or other wrench (such as a monkey wrench,etc.).

Claims

CLAIMS:

1. A socket for use with a ratchet wrench comprising:

a front segment having an axially extended bore which is shaped to fit snugly over the head of a threaded fastener in order to turn said fastener; and a rear segment adjacent to said front segment and adapted to be rotated by the pin of a ratchet wrench, wherein the outer lateral wall of said front segment has at least two flat surfaces which are opposite to each other.

2. A socket as claimed in Claim 1, wherein said outer lateral wall of the front segment has multiple pairs of flF,t surfaces, the flat surfacesof each pair being diametrically opposite to each other.

3. A socket as claimed in Claim 2, wherein said outer lateral wall of the front segment has multiple pairs of axial recesses, each recess being interposed between two successive flat surfaces so that the recesses alternate with the flat surfaces.

4. A socket as claimed in Claim 3, wherein said flasurfaces include a dulled edge adjacent to the free periphery of said front segment.

5. A socket substantially as described hereinbefore with reference to Figs. 2 to 4.

6. Any features of novelty, taken singly or in combination, of the embodiments of the invention hereinbefore described with reference to Figures 2, 3 and 4 of the accompanying drawings.
