The present invention relates to a switchable ratchet wrench for rotating a hand tool, in particular a fastener.

Ratchet wrenches have several advantages over conventional closed or open end wrenches. Fasteners to be tightened or loosened are typically in a restricted position with limited arc motion when the wrench is positioned on the fastener. When using an open and or a closed end wrench, only a limited arc of motion is made. It must be disconnected from the fastener and repositioned after its opening.

The ratchet wrench can be operated while keeping it on the fastener by easily returning the wrench to the initial point of motion by the ratchet mechanism without having to remove the wrench from the fastener. When providing the switching ratchet, the ratchet can be freely rotated in any direction required.

Conventional ratchet wrenches have an essential disadvantage compared to closed or open end wrenches. The wrench engagement surface of the fastener may sometimes be very far from the end of the fastener, i.e. a conventional automotive spark plug whose wrench engagement surface is located over the entire length of the spark plug, or the bolt that holds the fastener. Is a case extending through the fastener. Conventional closed or open end wrenches may simply pass through an end of a spark plug or bolt to contact the wrench engagement surface of the fastener. Conventional ratchet wrenches have a square drive that engages a square hole in the socket.

The ability of the socket to contact the wrench face on the fastener is thus determined by the length of the socket. Experience has shown that, in most applications, so-called "short" socket sets for short areas and so-called "deep" socket sets for fasteners and spark plugs with through bolts. Requires a set of sockets of different lengths, including. This is expensive to buy two complete socket sets. Also, when moving the wrench handle away from the fastener so that a long “deep” socket can be placed between the wrench and the fastener, the user must have a moment perpendicular to the direction of rotation necessary to avoid overstressing the fastener. Be careful not to work.

In order to eliminate the need for a plurality of sets of sockets, this has been overcome by providing a ratchet wrench having a hole through the wrench centered on the axis of rotation of the drive of the ratchet wrench. Sanborn, US Pat. No. 125,695, Mossberg US Pat. No. 1,165,995, and US Pat. No. 2,317,461 all show ratchet wrenches having through holes. Each patent wrench only fits into a single fastener size. Wilson, US Pat. Nos. 1,347,691 and 2,300,479, shows ratchets having through-holes that can use interchangeable sockets to use wrenches depending on fastener size, respectively. However, none of the wrenches shown in the patent change the ratchet direction without changing the wrench. In addition, all of them use lighter, smaller, and stronger sockets compared to standard square drive sockets, which makes commercial competition difficult with standard square drive sockets.

The ratchet wrench using the socket set is provided with a spring-loaded stopper such that the socket is fixed on the drive member of the wrench in normal use. Recently, a mechanism has been developed to quickly disconnect a socket from a wrench by contracting the stopper. Such mechanisms are shown in Robert's US Pat. No. 3,208,318 and Haznar US Pat. No. 3,532,013.

However, these instruments require a large number of parts and are therefore expensive and can be easily separated for repair.

Most conventional ratchet wrenches allow about 9 ° rotation between the socket and the wrench before the ratchet mechanism in the wrench is actuated to secure the socket to the wrench to rotate in the required direction. In some ratchets, the angle was reduced to allow the ratchet wrench to be used more effectively in the mating position, but this design was not entirely satisfactory.

Known ratchet wrenches cannot be used if the member to be tightened or loosened is adjacent to an obstacle that prevents the socket and wrench from being placed in the member. Conventional sockets have a rounded cross section and cannot be removed and rotated without the wrench in place. Therefore, a ratchet wrench cannot be used if the wrench itself cannot be fixed to the socket even if the socket is placed on the member.

No single ratchet wrench has yet been developed which has all of the above-mentioned advantages of having a quick release mechanism of the socket used, including having a through hole to eliminate the need for multiple sets of sockets.

According to one aspect of the invention, the ratchet wrench is provided to rotate the fastener. The ratchet wrench has a handle having a head at one end thereof, and the head has a circular hole formed through the center of the shaft.

The drive member is mounted on the handle and extends into a cylindrical hole for rotation about an axis with respect to the handle. The drive member is operatively connected to the fastener so that rotation of the drive member rotates the fastener. The drive member penetrates along the axis to form an extended hole. The latching means is provided to selectively latch the handle in both rotation directions with respect to the axis with respect to the drive member.

According to another form of this invention, the ratchet wrench which rotates a fastener is provided. The ratchet wrench has a handle with a head at its lower end. The head has a circular hole formed through the shaft center. The wall of the head forming the cylindrical hole has a ratchet over the entire perimeter of the wall. The drive member is mounted to the handle rotatably about an axis of rotation relative to the handle through a cylindrical hole. The drive member is operatively connected to the fastener so that rotation of the drive member rotates the fastener. The drive member also forms a slide face against the ratchet teeth in the head and a hole extending through the axis of rotation. A pawl is located between the slide face on the drive member and the ratchet teeth on the head and forms the first and second sets of ratchet teeth on the pawl facing the ratchet teeth on the head. Means are provided for moving the pawl between the first and second positions relative to the slide surface so that when the handle is rotated in the first direction with respect to the drive member in the first position, the pawl fits between the ratchet and the slide surface of the head. To allow the vehicle to rotate the handle in the opposite direction relative to the drive member. When the fool is in the second position with respect to the slide surface, the rotation of the handle in the opposite direction with respect to the drive member is prevented, and the moving means causes the rotation of the handle in the first direction with respect to the drive member.

According to another aspect of the invention, the drive member in the ratchet wrench forms two slide surfaces facing the ratchet teeth in the head. The poles are positioned so that a slide movement is made on each slide surface. Each fool forms the first and second sets of ratchet teeth on the pole facing the ratchet teeth on the head. A structure is provided to move the pole between the first and second positions relative to the slide surface, so that when the handle is rotated in the first direction with respect to the drive member in the first position, the pole is fitted on the ratchet of the head and the slide surface. The moving structure allows the handle to rotate in the opposite direction with respect to the drive member. When the fool is in the second position with respect to the slide face, the handle is prevented from rotating in the opposite direction with respect to the drive member, and the movable structure causes the handle to be rotated in the first direction with respect to the drive member. The slide surface is formed such that the pawl does not engage with the teeth on the head and at the same time the engagement of the pawl with the head acts to reduce the required angle of rotation between the drive member and the head.

According to another form of this invention, the adapter which can use the ratchet wrench and socket of this invention is provided with respect to the conventional square drive wrench and socket.

According to another aspect of the present invention, the hexagonal socket used for a ratchet wrench has a wrench face on its outer surface that can use a conventional open end or box wrench for tightening or releasing a member. Hex sockets can be used with standard sockets to form other hexagon sockets or deep sockets.

According to another form of this invention, the means for fixing a socket on a drive member is provided. In addition, a means is provided to disable the means for securing the socket so that the socket is separated from the drive member.

The invention will be more readily understood by the following detailed description taken in conjunction with the accompanying drawings.

According to FIGS. 1 and 3 to 5, the wrench 10 according to the first embodiment has a handle 20 having a head 22 at its end, and in the opposite direction of the head 22. It has a handle 24 for holding by a user. As shown in FIG. 3, the head 22 has a cylindrical hole 26 formed through the center of the shaft 27. The wall 28 of the head forming the cylindrical hole is provided with ratchet teeth 30 distributed parallel to the axis 27 and along the entire periphery of the wall 28.

The drive member 32 is provided with the cylindrical part 34 and the hexagonal drive part 36. The upper edge of the cylindrical portion 34 has a flange 38 which is mounted on the annular insertion member 40 in the wall 28 of the head 22 and rotates. The drive member 32 is secured to the handle 20 by fastening plates 42 coupled to the bottom of the cylindrical portion 34 by screws 44, as shown in FIGS. 3 and 5.

The fastening plate 42 has a diameter sufficient to contact the lower surface of the head 22 so that the drive member is separated from the handle 20. However, the drive member 32 is configured to be free to rotate in the head with respect to the shaft 27. As shown in FIGS. 3 and 4, the drive member 32 has a hole 48 extending completely through the member and centered on the shaft 27. The hole 48 forms a passage for the spark plug end, stud, rod, bolt, or other elongate object such that the ratchet wrench 10 is used in the fastener without using a deep dish socket.

This shape also allows the wrench to be in close contact with fasteners that allow the wrench to be used in confined spaces. It also reduces the force acting on the fastener by a wrench other than the rotational torque required to rotate the fastener.

The drive member 32 is formed with a slide face 50 and a spring receiving groove 52, which extend to the opposite side of the cylindrical portion 34 as shown in FIGS. 3 and 6. The slide surface 50 forms a curve with a radius larger than the radius of the cylindrical portion 34, whereby the edges of the slide surface coincide with the outer surface of the cylindrical portion and the center of the slide surface enters from the outer surface of the cylindrical portion. The pawl 54 is inserted between the drive member 32 and the wall 28 so as to rest on the slide surface. The pole 54 has an inner curved surface 56 to slide on the slide surface 50.

The pawls 54 form a first set of ratchet teeth 58 and a second set of ratchet teeth 60 on opposite sides of the inner curved surface 56. The vertical hole 62 is formed between the tooth 58 and the tooth 60 through the pole 54. The first and second sets of ratchet teeth 58, 60 face the ratchet teeth 30 on the wall 28. The V-shaped spring 64 is inserted into the groove 52 with its vertex 65 toward the head 22 and positioned at the center of the groove 52.

The drive member 32 is formed with one curved notch 67 and three curved notches 66 extending from the top surface 68 of the drive member towards the member. Notches 66 and 67 are located at an angle of 90 ° from the adjacent notch with respect to axis 27. The two notches 66 extend into the incision 69 in the cylindrical portion 34. The other notches 66 and notches 67 extend towards the insertion member formed by the groove 52 and the slide surface 50, respectively. The holes 62 in the pawl 54 are continuously aligned with the curved notch 67 when the pawl is positioned between the drive member 32 and the wall 28 as shown in FIGS. 7 and 8.

The annular conversion plate 70 is located on the upper surface 68 and has a pin hole 72 for receiving the conversion pin 74, the guide pin 75, and the knob pin 76. The switching pin 74 has a relatively large knob portion 77 and a relatively small pin portion 78. The hole 72 is sized so that the pin portion 78 passes but the knob portion 77 does not pass.

The pin portion 78 extends into the spring groove 52 between the spring 64 and the wall 28 through the curved notch 66. The knob pin 76 has a knob portion 77 but does not extend below the bottom of the switch plate 70. As shown in FIG. 6, the knob pin 76 is provided with a small hole 79 to receive one end of the rotating spring 85. As shown in FIG. When the main spiral body of the spring 85 is encased in the groove 67 of the drive member 32, the other end of the spring 85 fits into the hole 62 of the pole 54.

The elastic ring 80 has a notch 82 formed in the drive member 32 so as to support the pin and the switching plate on the drive member 32 as shown in FIGS. 5 and 6, and each switching pin ( It is provided to be seated in the notch 84 formed in the pin portion 78 and the guide pin 75 of 74.

The latch operation is as follows. The spring 64 presses the diverter pin 74 in either of two positions against the end wall 81 or 83 of the notch 66 as shown in FIG. The pin 74 rotates the plate 70 as it is moved between the end walls 81, 83. As the plate 70 rotates relative to the drive member 32, the spring 70 is tensioned and elastically presses the pawl 54 moving with the plate 70. When the pin 74 comes in contact with the end 81, the spring 85 pushes the pawl 54 to the first position on the slide surface 50 as shown in FIG. 7. When the pin 74 abuts the end 83, the spring 85 pushes the pawl 54 to the second position on the slide surface 50 as shown in FIG. 8. In the first position shown in FIG. 7, the pawl is sandwiched between the teeth 30 and one end of the slide surface 50.

In this position, rotating the head 22 in the direction of arrow 86 in FIG. 7 causes the ratchet teeth 30 on the wall 28 to slide along the first set of ratchet teeth 58. The pawls 54 move slightly along the slide surface 50 to provide sufficient clearance for the ratchet teeth 30 to slide over the first set of ratchet teeth 58. The spring 85 continues to push the pawl 54 to a first position between the teeth 30 and the ends of the slide surface 50 and the pawls are returned by the springs and latching operations are performed. However, if the handle 20 and the head 22 are rotated in the opposite direction in the direction of the arrow 88 with respect to the drive member 32, the fool is sandwiched between the slide surface 50 and the wall 28 to form a first set. The ratchet teeth 58 and the ratchet teeth 30 are engaged to rotate the joint while the drive member 32 and the head 22 are bitten together to loosen or tighten the bolt or nut.

The operator grasps the knob pin 76 and the switching pin 74 of the knob portion 77, and the second in the path limited by the curved notch 66 with respect to the end wall 83 as shown in FIG. By moving the pin 74 to the position, the ratchet action of the socket wrench 10 can be reversed. As shown in FIG. 8, when the handle 20 and the head 22 are rotated in the direction of the arrow 86, the fool 54 is placed between the slide surface 50 and the wall 28 of the head 22. As shown in FIG. Will be refitted. The second set of ratchet teeth 60 engages with the ratchet teeth 30 on the head and jointly rotates the handle 20 and the drive member 32. When the handle 20 and the head 22 are rotated in the direction of the arrow 88, the ratchet operation is performed. The ratchet teeth 30 slide along the second set of ratchet teeth 60 and the springs 85 return the pawls 54 to the second position for ratcheting to take place. The spring 64 continues to press the switching pin 74 toward the first end wall 81 or the second end wall 83 as the pin is located at the side of the center of the vertex 65. The diverter pin 74 bends the spring 64 to its maximum when the pin contacts the vertex 65 at the center between the edges of the curved notch 66. In this position, the spring 64 can move the pin toward both end walls of the curved notch 66 along the direction in which the pin moves.

Other structures of the switching mechanism of the wrench 10 are shown in FIGS. 9, 10 and 11. Some parts of this structure are identical to the above-mentioned parts and the same parts are dotted with the same numbers. According to this structure, the drive member 32 is formed with a curved notch 66 'extending from the upper surface 68' of the drive member into the insertion member formed by the slide surface 50 'and the spring groove 52'. do. The pawl 54 'has a notch 120 that slides 50 when the pawl is positioned between the drive member 32' and the wall 28 'as shown in FIGS. 10 and 11. 'Is continuously aligned with the notch 66' opened adjacently. The annular switching plate 70 'has a pinhole 72' which is located on the upper surface 68 'and accommodates the switching pin 74'. The switching pin 74 'has a relatively large diameter knob portion 77' and a relatively small diameter pin portion 78 '. The hole 72 'is holed so that the knob portion 78' passes, but the knob portion 77 'does not pass. The pin portion 78 'extends into the spring groove 52' through the curved notch 66 'adjacent to the slide surface 50'. A notch 82 'formed in the drive member 32' so as to support the switching pin and the switching plate on the drive member 32 as shown in FIG. 9 on the elastic ring 80 ', and each switching pin ( It is provided so that it may be settled in the notch 84 'formed in the pin part 78' of 74 '.

The latching operation is almost the same as the latching action of the pole 54 mentioned above. However, the latching operation of the elastic spring 85 is caused by the spring 64 'pressing the pin 74' extending into the groove 52 'with respect to both ends 81' and 83 'of the notch 66'. Is performed. The spring 64 'force acts through the pin 74' and the plate 70 'and the second pin 74' as shown in FIGS. 10 and 11, and the second pin 74 '. Is fitted against the wall of notch 120 and extends adjacent the slide face.

Again, according to the ratchet wrench 10 according to FIGS. 1 to 10, although the head 22 has a drive member 32 having an annular ratchet tooth 30 and a pole 54, The invention includes a configuration in which the drive member has an annular ratchet set and the head supports the pole.

The drive portion 36 of the drive member 32 is suitable for fixing any one of the sockets 14 to 18 thereon and the extension member 12 at the same time. The drive portion 36 forms an outer hexagonal surface 100 forming a male drive portion and an inner hexagonal surface 102 forming a female drive portion. The socket 16 shown in FIG. 2C has a female connection 104, which has an outer hexagonal surface 106 that can engage the inner hexagonal surface 102 of the drive portion 36. The socket 14 shown in FIG. 2B has a female connection 108 which has an inner hexagonal surface 110 which can be engaged with the outer hexagonal surface 100 of the drive portion 36. The design of the socket 16 is such that small bolts, nuts and the like can be used. The socket 14 may use a larger bolt or nut. The sockets 14 and 16 each have a hole coincident with the hole 48 so that the wrench 10 can be used in a fastener having a bolt extending into the hole 48 or the like. The socket 18 has a female connection 112 with an inner hexagonal surface 114 that engages with the outer hexagonal surface 100 of the drive portion 36. The length of the socket 18 is much longer than the length of the socket 14 to have the advantage of a deep socket in the wrench 10 when the shank diameter of the bolt or rod that secures the fastener is larger than the diameter of the hole 48. The extension member 12 has a male connection portion 116 that meshes with the drive portion 36 and a female connection portion 118 used with the socket 14 or 16 when the extension member is required.

Hexagon drive section 36 should be rigid to withstand higher rotational torque than square drive wrenches of the same size. In addition, the combined male and female drive portions of the hexagonal drive 36 have advantages over conventional square drives. Since the hexagonal dry part 36 can use a relatively small hexagonal socket such as the socket 16 and the extension member 12 having a female drive portion, and a relatively large hexagonal socket such as the sockets 16 and 18 on the male drive portion. , Hexagon drive unit 36 may be used over a wide range of socket sizes than the conventional rectangular drive. For example, a single-sized hex drive portion 36 may be used for the socket sizes typically required for use of 3/8 inch square drives and 1/2 inch square drives. The shape of the hole formed by the female hexagonal drive surface of the combined male and female drives such as the inner surface 102 allows passage of a bolt shank or the like that is not possible with a conventional square drive. It is not necessary to limit the advantages of the female / male combination drive to the ratchet wrench, but it is necessary to use a power wrench such as an air powered wrench 500 of FIG. 34, a breaker bar wrench such as a wrench 260 of FIG. A screwdriver manual socket wrench, such as the screwdriver wrench 502 of 33 degrees, or a wrench using a male / female drive unit can be used. In addition, the length and weight of the sockets 14 to 16 can be reduced compared to conventional standard sockets, and the width of the drive socket combinations can be equalized.

In addition, the socket wrench 10 is provided with a socket lock and quick disassembly means. As shown in FIGS. 3 and 5, the member 130 has a cylindrical portion 132 and two resilient downwardly extending legs 134. The member 130 is positioned in the hole 48 in the drive member 32 before attaching the diverter plate 70. The shoulder 136 formed between the cylindrical portion and the leg contacts the lower portion of the switching plate 70 to hold the member 130 in the drive portion 32.

The drive part 36 has provided the notch 138 on the opposite hexagonal side surface. Leg 134 extends into this notch as shown in FIG. The leg 134 shown on the left side of FIG. 5 has a shoulder 140 bent inwardly, which holds the outer hexagonal surface of the socket 16 or extension member 12. This holds the socket 16 or extension member 12 on the socket wrench 10 by frictional contact through the shoulder 140. The socket or extension member may be provided with a notch with respect to the outer hexagonal surface into which the shoulder 140 may enter. The leg 134 shown on the right side of FIG. 5 has an outwardly projecting shoulder 142 in frictional contact with the inner hexagonal surfaces of the sockets 14, 18. In addition, the sockets 14, 18 may have notches on the inner hexagonal surface that accommodate the shoulder 142. The elastic button 144 is attached to the cylindrical portion 132 as shown in FIG. The button is provided with an annular edge 146 that enters into the groove 148 on the cylindrical portion 132. The button has a large enough contact area for the operator to easily operate the socket log and quick release means.

By pressing the button 144 downward toward the drive member 32, the member 130 moves downward in the drive member, and the shoulders 140, 142 move downward on the cam edges 150, 152 of the notch 138. Slip The edges are angled to retract the shoulders 140 and 142 into the notches 138 when pressed to release the socket or extension member on the member 130 and the drive portion.

14 is a cross-sectional view of the drive portion 36 of the drive member 32. Notches 138 are formed on both sides of the drive portion in the flat portion of the hexagonal surface. The inwardly bent shoulder 140 of the leg 134 for securing the socket 16 onto the wrench will interfere with the passage of the object 250 having a diameter A where the wrench is positioned to rotate the fastener. . Object 250 may be comprised of, for example, rods, bolts, or other structures.

The modified design of the drive member 32 which prevented such interference is shown in FIG. In this variant design, the notch that receives the leg 134 for supporting the socket 16 is located at the corner between the two flat surfaces of the hexagon. The inwardly curved shoulder 140 extends from two adjacent hexagonal surfaces on the inner hexagonal surface 102. This frees the passage of the object 250 having the diameter A shown in FIG. 15, which cannot pass through the drive portion as in FIG. 14. It also uses a third leg 134 ″ lying in a third notch 138 ″ positioned between two flat surfaces of the drive 36. The third leg 134 ″ also has a curved shoulder 140 ″ supporting the socket 16 to increase the bearing capacity of the socket.

It will be appreciated that the socket wrench 10 has all the advantages of the aforementioned socket wrench.

The latching action can be switched without removing the wrench by simply moving the changeover pin. To switch the latch action, the knob portion 77 is always rotated in the direction of the wedge pole 54 between the head 22 and the drive member 32.

Thus, the drive portion 32 does not need to rotate relative to the head 22 when switching the wrench to switch the wrench with one hand.

17A to 20 illustrate a ratchet wrench 300 according to a fourth embodiment of the present invention. Many parts of the ratchet wrench 300 are the same as the parts of the wrench 10 described above. The same parts are shown with two dots (″) on the same number.

The ratchet wrench 300 has a handle 20 ″ having a head 22 ″. The head 22 ″ has a through cylindrical hole 26 ″ which is centered at the shaft 27 ″.

The drive member 302 has a cylindrical portion 304 and a hexagonal drive portion 306. The upper edge of the cylindrical portion 304 has a flange 308, which is configured to seat and rotate on the annular insert 40 ″ in the wall 28 ″ of the head 22 ″. Drive member 302 is secured to handle 20 ″ by retainer ring 303 located in groove 305 in drive member 302 and groove (not shown) in wall 28 ″. This causes the drive member 302 to rotate on the axis 27 ″ with respect to the head 22 ″.

The drive member 302 has a large cylindrical hole 310 which extends fully through the drive member 302 and is centered on the axis 27 ″ when mounted in the head 22 ″. The hole 310 has the shape and characteristic of the hole 48 mentioned above.

The drive member 302 is provided with opposing slide surfaces 312 and 314 as shown in FIGS. 17A and 20. Slide surfaces 312 and 314 are planar.

The slide surface 312 extends perpendicular to the radial line 316 extending from the axis 27 ″ to the shortest surface with the slide surface 312. However, the slide surface 312 is not perpendicular to the radial line 316 crossing at the shortest point on the axis 27 ″. In a preferred embodiment of the present invention, the head 22 ″ has 48 ratchet teeth 30 ″ and an angle θ between the slide surface 314 and the line 317 perpendicular to the radial line 316. Is 3 ° 45 ′. The first fool 318 is located between the ratchet teeth 30 ″ in the head 22 ″ and the slide surface 312. The second fool 320 is located between the slide surface 314 and the ratchet teeth 30 ″. Two fools 318 and 320 are placed on each slide surface 312 and 314.

Each pole 318, 320 has a first set of ratchet teeth 322 and a second set of ratchet teeth 324 facing the ratchet teeth 30 ". The vertical hole 326 is formed through the poles 318 and 320 between the teeth 322 and 324 as shown in FIG.

The drive member 302 is formed with two curved notches 328 and two straight notches 330 as shown in FIG. Curved notch 328 extends from top surface 332 of drive member 302 into cutout 334 in drive member 302. The straight notch 330 extends from the upper surface 332 and opens into the gap formed by the slide surfaces 312 and 314. The vertical holes 326 in the poles 318 and 320 are continuously aligned with the straight notches 330 when the pole is positioned between the slide face and the ratchet teeth 30 ".

The annular diversion plate 336 is located on the top surface 332 and has diversion pins 338 and 340. When the switching plate 336 and the switching pins 338 and 340 are fixed to the cylindrical portion 304 by the elastic ring 80 ″ in the same manner as the switching pin 70 is fixed to the drive member 32, As shown in FIG. 18, the transition pins 338 and 340 extend into the curved notch 328.

The switching spring 342 selectively pushes the switching pins 338 and 340 against one end or end of the curved notch 328. The switching spring 342 holds the switching pins 338 and 340 against the curved notch 328 by contacting the contact portion 346 of the switching spring 342. When the diverter plate 336 is rotated clockwise as shown in FIG. 18, the diverter pins 338 and 340 move the diverter pins 342 while the diverter pins 342 move to form a curved notch (opposite to the end 344). Contacting end 348 of 328.

Then, the contact portion 350 of the switching spring 342 holds the switching pin with respect to the end 348 until the switching plate 336 is rotated counterclockwise by the operator as shown in FIG. .

The latch operation is as follows. The switching spring 342 pushes the switching pins 338 and 340 to one of two positions with respect to the ends 344 and 348 of the curved notch 328. The position of the switching plate 336 is determined by the positions of the switching pins 338 and 340.

Pool pins 352 and 354 are provided to extend through the straight notches 330 and extend into the vertical holes 326 of each of the poles 318 and 320. Continuous main spring 343 extends over the entire periphery of drive member 302. The main spring 343 can be moved by rotating about the axis 27 ″ by the switching pins 338 and 340 as shown in FIG. When the diverting pins 338, 340 contact the end 344 of the curved notch 328, the main spring 343 moves to the first position 318, on the slide surfaces 312, 314 shown in FIG. 20. Press and hold the phosphol pins 352 and 354 to move 320. When the diverter pins 338 and 340 contact the end 348 of the curved notch 328, the diverter pins 338 and 340 are moved to the second position shown by the pole 318 shown in dashed line in FIG. The juice springs 343 and the phosphines 352 and 354 are moved to move the fools 318 and 320.

In the first position shown in FIG. 20, only the first set of ratchet teeth 322 of the first pool 318 fit between the teeth 30 ″ and the slide surface 312. The first set of ratchet teeth 322 on the second pole 320 are latched teeth 33 ″ by a slight angle between the slide surface 314 and the line 317 perpendicular to the radial line 316. Does not mesh with

In this position, when the head 22 ″ rotates in the direction of the arrow 356 in FIG. 20, the first pole 318 is sandwiched between the slide surface 312 and the ratchet teeth 30 ″, so that the bolt or nut The drive member 302 and the head 22 ″ are fastened together so as to tighten or loosen, so that they can be combined and rotated together.

If the head 22 ″ rotates in the direction of arrow 358 in FIG. 20, the first pool 318 has a ratchet tooth 30 ″ with a first set of ratchet teeth 322 on the first pool 318. FIG. It will be moved very little along the slide surface 312 against the main spring 343 force to provide sufficient clearance to slide over. The main spring 343 continues to push the first fool 318 to the first position, so the fool 318 is returned by the spring force and a latching action takes place. However, before the second set of ratchet teeth 322 of the first pole 318 and the ratchet teeth 30 ″ on the head 22 ″ are engaged by the pawl 318 spring force, the second The pawl 320 is moved such that the first set of ratchet teeth 322 of the second pole is engaged with the ratchet teeth 30 ″ on the head 22 ″.

The second fool 320 may rotate in the direction of arrow 356 with the drive member 302 fastened to allow the first set of ratchet teeth 322 to rotate with the ratchet teeth 30 ″.

Thus, the angle of rotation of the drive member 302 relative to the head 22 " between the latch engagement positions using the first and second poles 318, 320 is less than if only a single pole is used. The reduced angle between these ratchet engagement positions extends from the axis of rotation 27 ″ and slides at an intersection of other angles from the radial line 316 that intersects the slide surfaces 312 and 34 closest to the axis 27 ″. It is possible by forming (312, 314). For example, if 48 latch teeth 30 ″ are formed on a head 22 ″ having a single poll, the head 22 ″ is 7 ° 30 between the engagement of the pawl and the ratchet teeth 30 ″. Can rotate by '. In contrast, positioning two poles to engage the rat teeth 30 " can reduce the rotational angle between engagements by 3 ° 45 '. Thus, it will be appreciated that the slide surface 312 does not need to be perpendicular to the radiation 316. In addition, the slide surface 312 may have a slight angle with respect to the line 317 perpendicular to the radial line 316, like the slide surface 314. It should also be understood that the slide surfaces 312 and 314 do not need to directly face each other as shown in FIGS. 17A-20. If the slide faces 312 and 314 are configured to engage the pawls 318 and 320 at the same time as the teeth 30 ", the ratchet mechanism of the wrench 300 will be strong, thus using the wrench 300 abnormally roughly. It can be done. Simultaneous latching operation may occur when the slide surface 314 is parallel to the line 317 shown in FIG.

Ratchet operation of the ratchet wrench 300 can be achieved by holding the diverter plate 336 and moving the diverter pins 338, 340 relative to the end 348 of the curved notch 328. This moves the primary springs 343 and the poolins 352 and 354 in the straight notches 330 to move the first and second poles 318 and 320 to the second position. When the handle 20 ″ and the head 22 ″ are rotated in the direction of the arrow 358, one of the fools 318 and 320 has a tooth 33 in which the drive member 302 and the head 22 ″ are engaged. ”) Is engaged. When the head 22 " is rotated in the direction of the arrow 356, the latch operation is performed. Also, only one of the poles 318, 320 will engage the latch teeth 30 " at a given tilt angle position. Thus, the separation of the reduced angle between the latch engagements takes place when the pool is in the second position.

The cylindrical drive portion 304 of the ratchet wrench 300 can fix the sockets 14 to 18 and the extension member 12, and mentions the female and male combination drive portions 36 of the socket wrench 10. It has a shape.

21 to 24, the advantages of the hexagon sockets 14, 16 and 18 are described. As shown in FIG. 21, the portion 108 of the socket 14 has an outer hexagonal surface 360, which is a wrench engagement surface for rotating the socket 14 with a conventional open end wrench 362. To form.

In FIG. 22, the hexagon socket 14 and the conventional socket 364 are compared. In Fig. 22 the dimension a is the height of the socket. Dimension (b) is the diameter of the opening of the hexagon socket 14 through which the shank of the bolt can protrude and at the same time the opening of a conventional socket 364 to accommodate a square drive that is not large enough to allow a large bolt or shank to pass through. Size. The dimension c is the depth of the actual nut engagement portion of the socket. The dimension d is the built in depth.

Comparing the hexagon socket 14 and the conventional socket 364, the overall size of the hexagon socket 14 is reduced by eliminating the portion forming the assembly depth d. The weight of the hexagon socket 14 is smaller than that of the conventional socket 364, and in the case of the socket having the same dimension, the portion forming the assembly depth d is removed, and the hexagon outer surface 108 and the size (b) of the socket 14 are removed. It is reduced because of the large hole that forms. The dimension b on the hexagon socket 14 is larger than the dimension b on the socket 364 in the case of a socket of the same dimension, so that a large bolt shank or the like can be passed if necessary.

According to FIG. 23, the present invention provides a deep socket 370 by using a conventional socket 366 and a hexagon socket 14 of a suitable size having a square drive portion 368. That is, the deep socket 370 shown in FIG. 3 works with a conventional rectangular drive socket wrench.
