Definitions
- the invention relates to a ratchet according to the preamble of claim 1. (see CH-A-244 678).
- Ratchets are usually designed as universal tools, i. H. in the head of a ratchet is an inserted holder, which in turn stores an insertable or attachable tool, for example a screwdriver, wrench, or the like.
- an insertable or attachable tool for example a screwdriver, wrench, or the like.
- the holder rotatably mounted in the head for receiving of a so-called bit, on the end of which is a hexagon key is designed for a hexagon socket head screw. The bit can too pick up a coupling rod, at the other end a screwdriver or the like is included.
- the present invention is specifically concerned with the design the actual ratchet mechanism, which is an easy switch between right-hand and left-hand (for tightening or loosening of screws, nuts and the like).
- the object of the invention is to provide a ratchet of the type mentioned above, which on the one hand has a very compact structure, so that with This ratchet can also be worked in hard-to-reach places can, on the other hand preferably also switching between Right and left turns should be possible without the ratchet from the part to be turned (screw, nut, ...) must (see also FR-A-1 035 176).
- the working direction of rotation (tightening a screw or loosening a screw) by the Handle is rotated about its longitudinal axis.
- the one rotary position corresponds, for example, to the right gear, which corresponds to the other rotational position Links gear.
- one of the rolling elements is replaced by the Spring means from the holder, d. H. of those on the perimeter of the holder trained receiving recesses moved so that this rolling element practically does not matter when using the tool.
- the other rolling element is from the associated rolling element stop member by prestressing it while overcoming that of the spring means preload applied directly to the rolling element in the direction Holders pressed so that the rolling element in a recess on Circumference of the holder is located. If the head is in relative to the holder Working direction of rotation is rotated, so the rolling element between the him straight receiving recess and an area of the inner surface pinched the head, so that a twist of the handle and hence the head takes the holder. The head turns in the direction of return rotated, this rolling element can be its associated rolling element stop member push back against its bias and thus jump into the adjacent recess in the circumference of the holder. This Jumping is repeated according to the stroke of the return movement.
- the ratchet according to the invention works practically without slippage. Once the If the handle is turned in the direction of rotation, the handle also turns Holder with the bit inserted.
- the entire ratchet mechanism is symmetrical with respect to one plane formed which the longitudinal axis of the handle and which the head penetrating axis of rotation of the holder intersects.
- the process described above therefore runs in a corresponding manner the other rolling element if, for example, from clockwise to counterclockwise was switched.
- the working direction and accordingly the The return direction of this tool depends on the rotary position of the Handle with respect to the shaft receiving the handle.
- the rotary position the handle determines which of the two rolling elements of the circumference of the holder sitting in the head is continuously moved away, and which rolling element due to the relatively large preload of the associated one Rolling element stop member pressed against the circumference of the holder becomes.
- balls can also be used as rolling elements, preferably
- cylindrical pins as they are in principle of needle bearings are known here.
- Such pins give the ratchet mechanism considerable stability and durability.
- Corresponding to the cylindrical Pins are within the scope of the holder inserted into the head axially parallel recesses formed, which have a partially cylindrical shape and thus encompass part of the circumference of the pin in question.
- the spring means that act directly on the two rolling elements the task, in the case of right-hand or left-hand rotation, the one rolling element from move the peripheral surface of the holder.
- An embodiment provides for this the invention that the rolling elements against the rolling element stop members preloading spring means as an open ring locking spring are formed, which in an annular locking spring receiving groove sits in a holder receiving opening of the head, the Contact the ends of the open ring locking spring with the rolling elements.
- the ends of the ring locking spring press the two rolling elements the holder and its recesses away towards the handle.
- the position of the end face of the insertion end sitting in the shaft of the handle and the dimensions of the rolling element stop members are chosen so that the spring means these rolling element stop members over the between the ends of the ring locking spring and the rolling element stop members seated rolling elements a bit towards the handle push back as long as not one of the rolling elements (or both Rolling elements) assigned by them biasing means in the direction of Holders are biased to the part by the ring locking spring on the Rolling elements to overcome applied preload.
- the Rolling element stop members are designed as cylindrical pins which axially parallel to the shaft and the handle and parallel at a distance are stored to each other in the shaft, and that the pin on it the rolling elements facing end face an investment projection for the Have rolling elements. From this investment advantage and in part from the end face of the rolling element receiving member itself is then the associated rolling elements added, being by the ring locking spring is biased towards the rolling element stop member.
- the ratchet mechanism according to the invention is now designed so that the moving of the rolling elements from the one rotatably seated in the head Holder is only possible as long as not on the part of a rolling element stop member a preload is applied to the associated rolling element through which the rolling element is pushed between the head and the holder is so that the rolling element is in a recess on the circumference of the rolling element.
- ratchet mechanism in the At least one end of the handle on the end of the handle recessed two spring seats, in each of which sits a coil spring, the a ball axially loaded towards the head, the location of the Spring seats, the coil springs and the balls so on the location of the the rolling element stop members forming pin is matched that in one of the two rotary positions of the handle, one with one of the Balls aligned pins from the bias of the coil spring is pressed against the associated rolling element and thereby the rolling element between the holder and the head while the other is pushing Pin of the spring means against the end face of the insertion end of the Handle is pushed back.
- a locking or locking position is provided.
- the Invention before that additional spring seats in the insertion end of the handle are provided with associated coil springs and balls and that in a third rotational position between the handle and shaft two pins pretensioned by the coil springs (rolling element stop members) the two rolling elements between the holder and the head push to lock these two parts together in a rotationally fixed manner.
- the ratchet according to the invention is characterized by a compact Structure and consists of a few individual parts.
- the parts of the ratchet can be made into an operational tool relatively quickly and easily Assemble.
- Figure 1 shows in perspective a ratchet 2 with a head 4, in which a Bit 6 is stored in the form of a hexagon pin.
- the axis of rotation of the Ratchet corresponds to the axis passing through head 4 and bit 6.
- Bit 6 is inserted into an Allen screw 10, see above that the cap screw 10 by tightening a handle 8 of the ratchet 2 can be tightened.
- the "getting dressed” here means that the Handle 8 essentially pulled out of the plane of the drawing becomes.
- This actuating movement of the ratchet 2 is also in the following are referred to as the working direction.
- the opposite movement the handle 8, that is, the movement approximately in the drawing plane is a movement in the direction of rotation of the ratchet in which the head screw 10 stops and only the handle 8 moved together with the head 4 while one is still below explained in more detail, in the head 4 seated holder 50 for the bit 6 in the Head screw 10 stops.
- Ratchet 2 Before going to the details of that shown schematically in Figure 1 Ratchet is discussed in more detail, the operation of the ratchet 2 for switching between clockwise and counter-clockwise or for setting a locking or locking position are explained.
- the handle 8 sits with an insertion end 81 in one piece the head 4 formed hollow shaft 42. Over a part of the circumference of the shaft 42 extends through the wall of the shaft 2 Window 44, in the edge facing the handle 8 three wells spaced apart (see Post 49 in Figure 5 bottom right) are trained. From one described below The mechanism is the handle 8 accommodated in the shaft 42 biased towards the end thereof so that one of the insertion ends 81 of the Handle 8 radially outwardly projecting projection 82 in the window 44 protrudes and due to the aforementioned bias of the handle 8 towards the end of one of the three with the appropriate rotary position Wells (49 in Figure 5) engages.
- the cylindrical shaped insertion end 81 of the handle is from radially penetrates a receiving bore 83.
- the location hole 83 has an internal thread at least in the area shown below in FIG. 2.
- the handle 8 can be about its longitudinal axis twist in shaft 42 to a limited extent, the extent the twist depends on the circumferential length of the window 44.
- the handle 8 with its insertion end 81 is still from below Springs described in more detail (which can be seen in FIG. 2) in FIG. 2 biased to the right, ie towards the end of the handle 8. hereby the projection 82 comes into contact with the one facing away from the head 4 Edge of the window 44, with a corresponding relative rotational position between handle 8 and shaft 42 in one of the three depressions 49 intervene and so one of the three defined rotary positions of the To take handle 8 with respect to the shaft 42.
- Figure 4a shows the individual components of the total shown in Figure 1 Ratchet 2.
- the handle 8 On the right in Figure 4a is the handle 8 with its insertion end 81 shown.
- a Set of four spring seats 85a, 85b, 85c and 85d formed in the end face of the insertion end 81 .
- the spring seats are each designed as blind holes and are in the shown in Figure 4b about the central longitudinal axis of the handle 8 or its engaging end 81 arranged at the same distance.
- a coil spring 87 is received in each spring seat 85a-85d which each owns a small ball 88. As can be seen in Figure 2, the coil springs 87 press the associated small balls 88 against the bottom surface of the recess of the shaft 42 to thereby Insert 81 and with this the handle 8 to the right in FIG. 2 pretension.
- the head 4 is shown on the left in FIG. 4a, which has a circular receiving opening 45 owns. In the middle of the height of the receiving opening 45 is a locking spring receiving groove 46 for receiving a ring spring trained locking spring 43 formed. At the top of the There is another receiving opening 45, not here with reference numerals provided groove to accommodate a steel ring spring trained retaining spring 47, with the help of the holder 50 in the receiving opening 45 of the head 4 is secured.
- the holder 50 is penetrated in the middle by an opening in which a second retaining spring 52 an ejector button 51 is received.
- the holder 50 receives bit 6, wherein the bit 6 has a circumferential groove and between them Circumferential groove and an annular groove inside the central opening of the Holder 50 is a further retaining spring 52.
- the ejector button is turned on another bit inserted into the holder 50 again into the one in FIG. 2 shown upper position pressed.
- each of the rolling elements 93 and 94 is designed as cylindrical pins.
- To each of the rolling elements 93 and 94 includes a roller stop member 92 and 91, respectively.
- Figure 4c shows a perspective view of the shape of the rolling element stop member 91.
- the rolling element stop member 92 is designed in the same way.
- the rolling element stop member 91 or 92 has the shape of a cylindrical pin with a flat end face, which in Figure 4c is covered. At the other end of the pin there is a partial end face 91a, on which a projection 91x arises, the stop surface 91c and a narrow end face 91b.
- the two Surface sections 91a and 91c form a receiving or stop area for the rolling element associated with this rolling element stop member 91 94th
- Figure 3 shows a horizontal section through that shown in Figure 1 Gun. It can clearly be seen that the shaft 42 is made in one piece with the ring body trained head 4 is formed. In the intermediate area are located between the receiving opening of the shaft 42 and the head 4 two bearings designed as cylindrical bores for receiving each of a rolling element stop member 91 or 92.
- a plane of symmetry runs perpendicular to the plane of the drawing in FIG. 3, which is the central longitudinal axis of the handle 8 and the common Includes axis of rotation A of the holder 50 and the head 40. The entire ratchet mechanism is symmetrical with respect to this plane of symmetry built up.
- the two are designed as pins Rolling elements 93 and 94 each in a recess 53 on the outer circumference of the holder 50, with one end of the Ring locking spring 43 abuts.
- the handle 8 adjusted with respect to the shaft 42 so that this rotational position the locking position "S" for the ratchet is defined.
- the springs 87 on the Balls 88 applied bias overcomes the ring locking spring 43 applied to the rolling elements 93 and 94 tension, see above that these two rolling elements 93 and 94 in the direction of the holder 50th be pressed and thereby by two of the partially cylindrical recesses 53 are included.
- the rolling element stop member comes 91 with its partial end face and the inclined surface (91c in Figure 4c) for contact with the outer circumference of the designed as a pin Rolling element 94, so that this rolling element 94 between the receiving it Recess 53 and the opposite of this recess Wall of the head 4 is pinched.
- This will create a Relative rotation between head 4 and holder 50 prevented, so that Holder 50 and the tool insert or attachment coupled thereto be turned with the head 4.
- the Working direction of rotation opposite to the arrow direction shown in Figure 5 correspond clockwise.
- the handle 8 is opposite the shaft 42 rotated so that the rotational position of the left gear “L” equivalent.
- the spring seat 85b is aligned with the rolling element stop member 91 across from.
- the coil spring seated in this spring seat 85b presses the associated ball against the lower end face of the rolling element stop member 91, so that the rolling element stop member 91 the associated Rolling element 94 presses in the direction of the holder 50. So will that Handle 8 with the head 4 in the direction of the arrow counterclockwise rotated, the holder 50 is due to the between the holder 50th and the head 4 pinched rolling element 94.
- the other rolling element stop member 92 is from the associated end the ring locking spring 43 biased towards the handle 8, and in the absence of a corresponding counterforce (by one of the coil springs in one of the spring seats 85a-85d is the lower end face of the Rolling element stop member 92 on the end face of the insertion end 81 of the Handle 8 on.
- the location of the end face of the insertion end 81 and the Dimensions of the rolling element stop member 92 and the associated Rolling element 93 are selected so that the rolling element 93 is completely of the Holder 50 and the recesses 53 located on its circumference moved away is.
- FIG. 7 shows the reverse process with respect to FIG. 5.
- the rolling element stop member 92 in alignment with the spring seat 85c Insert end of the handle opposite, so that the rolling element stop member 92 associated rolling elements 93 in the direction of the holder 50 is pushed. If the head 4 is turned in the direction of the arrow, take this rotary movement due to the pinching of the rolling element 93 between head 4 and holder 50 with the holder 50.
- a counter turn the direction of the arrow in FIG. 7, ie counterclockwise, causes a reset stroke (creak effect), the holder 50 with its tool insert and the screw engaged with it or mother stops.
- the locked position of the ratchet can be omitted, so that only one switchover between counterclockwise and clockwise rotation is possible. Needed for this then only in the end face of the insertion end 81 of the handle 8 two spring seats (with a corresponding number of coil springs and small balls) to be present. The mode of operation according to FIG. 6 would then be dropped.
