EP1693163A2 - Handle with magazine for tool inserts, in particular screw driver inserts - Google Patents

Abstract

The handle has a magazine (M) attached in a cavity of the handle for receiving several screwdriver inserts (4). The magazine consists of a sleeve (5) provided with a retaining device for the inserts, and a core (9) provided with a stop unit. The core comes out when the sleeve stops and is displaced relative to the handle, with a cap (3) detached from the handle, such that the inserts kept at the sleeve can be projected from the cavity.

Description

The innovation concerns a magazine handle for tool inserts, in particular for receiving replaceable screwdriver inserts.

Such handles are known in various embodiments from the market and literature. Usually, the handles are equipped on their front with a device for receiving the screwdriver inserts.

In a known embodiment, the end portion of the handle is designed as a removable cap that closes a number of blind holes in the handle. In these blind holes Schraubendreher Elnsätze are housed. Disadvantage Is in this embodiment that for removing the screwdriver Einsäfize the cap must be unscrewed, the screwdriver inserts are not visible from the outside and only six pieces can be accommodated in the handle. Such a handle is shown for example in the catalog Wiha 2001/2002 on page 134.

In a similar embodiment, the end portion of the handle is designed as a rotatable cap which has a bore on the same pitch circle on which the blind holes lie in the handle. It is further provided with a latching device by which the cap is held in a position in which the bore is in a position between the blind holes in the handle. The screwdriver bits can not fall out. You can also remove without the firing the blind holes part must be unscrewed. The disadvantage, however, is that the Screwdriver inserts still not visible from the outside and are limited in number to six.

The same applies to a screwdriver known from DE-C2-38 30 859. Bel this the housing of the screwdriver inserts is similar solved, however, the screwdriver inserts are housed in blind holes in the front part of the handle and the head piece of the handle is designed as a turntable having a bore for removing a screwdriver bit.

A magazine handle disclosed in DE-U1-93 02 534 also has blind holes extending in the axial direction, which are closed by a rotatable cap. The latter is connected by a snap connection with the handle. In the cap, a pivotable lid is used flush with the surface, whose width corresponds approximately to the diameter of a blind hole. If, by turning the cap, the lid is brought to a stop via a blind hole and opened, then a screwdriver insert can be removed from the blind hole quiver. However, the disadvantage is the form-technically complicated construction for the production of cap and lid by injection molding. Moreover, the surface of the cap is not smooth. The gaps around the lid interfere with the palm of your hand when working with the screwdriver. Another disadvantage is the small number of six screwdriver inserts to be accommodated.

In one known from DE-U1-298 10 876 magazine handle a slide magazine is provided for receiving screwdriver inserts. Its end is formed so that it forms flush with a part of the surface of the end surface of the handle. In order to pull the magazine out of the handle, it has laterally a hook-shaped approach, which is embedded in a recess in the handle so that a trough for attachment of a fingertip remains. This shape is disturbing in the hand when working with the handle. In the magazine stand quivers are formed for inserting and removing the screwdriver inserts. The disadvantage here, however, that the magazine must be pulled out of the handle very far to remove the inner inserts. In addition, only a maximum of six inserts are included in the magazine, which are not visible from the outside.

From EP-B1-0 674 567 a cartridge-type magazine screwdriver is known. In a substantially cylindrically shaped handle, a first shaft of a receiving device for screwdriver inserts is firmly inserted. The back part of the shaft protrudes into the cavity in the back of the handle. On the rear part of the shaft, a second tubular shaft is mounted, which is movable on the first shaft in the longitudinal direction and to which a magazine for receiving the tool inserts is attached. A closure lid of the magazine is mounted on the second shaft and movable therewith. The disadvantage here is the substantially cylindrical shape of the relatively long handle, which is very unwieldy and does not meet the requirements of a good ergonomic shape. Another disadvantage is that the tool inserts are not visible when the handle is closed.

A well-known from WO-A1-005 106 storage compartment for screwdriver inserts is accessible, that you can move an outer handle axially against an inner handle part. The disadvantage here, however, is that when using the screwdriver, the torque must be introduced via the outer handle part, which forms substantially the entire length of the handle enclosed by the hand. However, it is not given a stable connection from the outer to the inner handle part. The operating zones for releasing the connection between the handle parts are also such that they trigger disturbing sensations when using the screwdriver in the hand enclosing the handle. The locking can also solve the latching. The screwdriver inserts are difficult to see from the outside.

The recognizability of the screwdriver inserts is particularly important for sales in the self-service area, because the prospective customer wants to recognize as possible all the details of the product before making a purchase decision, in particular the number and type or types of contained inserts.

Thus, an important object of the invention is to design a magazine handle for tool inserts so that it has a good ergonomic shape and can accommodate more than six screwdriver Elnsätze that can be quickly and easily removed from the magazine at any time. The inserts should also be clearly visible from the outside.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 16.

According to the invention, this object is achieved in the catfish that an ergonomic shape of the handle is specified, this handle in the rear of a cavity in In the form of a stepped bore, In which a two-cell, short-built magazine is housed, which is telescoped together when the closure cap is placed on the handle satgesetzt.

The magazine consists of a magazine sleeve and a magazine core, both preferably made of plastic by injection molding. The magazine sleeve has a collar of significantly increased diameter, on which at least one holding device for the screwdriver inserts is attached. These sit with the end face of the shank on the cap-facing side of the collar. On this side, on the collar, extending in the radial direction, low web-like elevations are formed, which form positioning aids for the screwdriver inserts. Instead of the radial webs low quiver-like depressions may be formed in the collar plate, which correspond to the hexagonal profile of the shafts of the screwdriver bits, but are partially open radially outward.

The holding device consists in a first embodiment of a permanent magnet, preferably a ring magnet which is fixed to the collar plate. The screwdriver bits are held in place by being attracted to the ring magnet. An attraction would also be achieved if a ring magnet of smaller diameter is attached to the cap-facing side of the cartridge sleeve so that the screwdriver inserts abut the shaft laterally on the magnet. Instead of a ring magnet and several pin-shaped or plate-shaped individual magnets can be axially oriented fixed in the collar plate and hold the screwdriver inserts on its end face.

In the region of the larger diameter of the stepped bore, the collar plate of the magazine sleeve is smoothly guided, in the region of the smaller diameter a cylindrical extension of the magazine sleeve.

The magazine sleeve has a stepped bore whose larger diameter lies on the side facing the front part of the handle. In the stepped bore of the magazine core is guided axially movable. He has at its front part of the handle end facing a stop element in the form of a federal or an attached snap ring and a bore in which a coil spring is guided. It rests with its other end at the bottom of the cavity or in a hole emanating from the bottom. The spring is stretched when pressing the magazine into the handle - when placing the cap on the handle -, We lock the Detached cap, the spring pushes the magazine core so far into the magazine sleeve until the collar abuts the step in the hole in the magazine sleeve and the magazine core, while continuing to act spring force, the magazine sleeve in the further movement moves until the edge of the collar on Stop cam comes to the plant, which protrude from the wall of the cavity. The magazine is now so far out of the grip that the inserts can be easily accessed and an insert is easily removed or can be used again in the magazine.

Bel a second embodiment, the holding device consists of spring elements, which, axially or radially oriented, are integrally formed on the magazine sleeve and hold the screwdriver inserts clamped.

The cap has, starting from the bottom of the handle-side cavity, a cylindrical or prismatic approach, which is connected by a snap connection with the cap-side end of the magazine core The cap is thus always connected to the handle and does not need when removing a screwdriver bit be held or filed. When placing the cap on the handle is pushed back over the connection to the magazine core and stretched the spring. The dimensions of the magazine and the cap are coordinated so that the tips of the screwdriver bits, with the cap sitting on the handle, protrude into an annular cavity formed between the cap wall and the hub. The cap is preferably made of crystal clear plastic, so that the tips of the screwdriver bits are clearly visible even when the handle is closed from the outside.

The device for locking the cap on the handle is preferably designed in the form of a bayonet closure. In this case, engage segments of a ring land on the cap with a cam in corresponding grooves, which are formed in the cavity of the handle. In the grooves transversely rounded webs are formed, which cause when closing or loosening the cap, a resistance must be overcome - the segments of the annular web einfedem - before the cap can be brought into the position in which they are released from the handle can be.

25 a one-piece cartridge sleeve

As shown in FIG. 1, in the front part of the handle 1, a shaft 2 of a receptacle for replaceable screwdriver inserts 4 is firmly inserted, usually by spraying the handle on the inserted into the mold shaft 2 by injection molding. A cap 3 is placed on the handle 1 and secured by a locking device 15. A magazine M has a sleeve-like magazine sleeve 5 with a collar 6, a ring magnet 7 and a magazine core 9. It is inserted with the attached screwdriver inserts 4 in a stepped bore 8, 13 in the handle 1, a coil spring 12 is tensioned.

The magazine sleeve 5 is guided with the projection 5a in a bore 8 of smaller diameter and with the collar 6 in a bore 13 of larger diameter. Both holes 8, 13 form a cavity in the rear part of the handle 1 for receiving the magazine M, which is arranged coaxially to the handle longitudinal axis A of the handle 1 and limited axially displaceable.

The magazine core 9 is guided in a stepped bore 11 in the magazine sleeve 5. 14 are stop cams on which the edge of the collar 6 comes to rest when the spring 12, the magazine m from the handle 1 pushes. By a snap connection 16, the cap 3 and the magazine core 9 are connected together. The screwdriver bits 4 sit with the end face on the surface F of the collar 6 and are held by the magnetic force of the ring magnet 7. With the tips protrude the screwdriver bits 4 in an annular cavity 3a of the cap 3, wherein the distance between the surface F of the collar 6, sit on the screwdriver inserts with the end face and the bottom 3e of the annular recess 3a in the cap third is seated on the handle 1 seated cap 3 so that the screwdriver bits 4 are held almost free of play in the axial direction. Thereby During use of the screwdriver, no disturbing noises can occur and the inserts are always stored safely.

The cap 3 is made of clear transparent plastic. At least the lateral surface 3d of the cap is smooth, so that in this area the full transparency is given; the rest of the area may be frosted for design reasons.

Fig. 2 shows the handle with the magazine pushed out M. The magazine core 9 is moved so far in the bore 11 by the spring 12, that the collar 10 bears against the step in the bore 11 of the magazine sleeve 5. He has this further taken to the abutment of the edge of the collar 6 to the stop cam 14. The magazine M is now pushed so far out of the cavity of the handle that the screwdriver inserts 4 are exposed to access, but you can not from the magazine M fall off and fall out of the handle 1, because they are held by the ring magnet 7. The cap 3 is connected by the snap connection 16 fixed to the magazine core 9 and does not need to be held as a single part in one hand. The two-part construction of the magazine M, consisting of the magazine core 9 and the magazine sleeve 5, is particularly advantageous in that it allows a long stroke of the magazine M and a long opening stroke for the cap 3, so that the screwdriver inserts 4 well taken the opening between the cap 3 and handle 1 and can be used again in the magazine M.

Fig. 3 shows a cross section along the line I-I through the handle 1 in Fig1. On the body of the handle 1, the shell of Welchkunststoff 1a is shown, which is not shown in the other figures. The guided in the bore 11 of the magazine sleeve 5 magazine core 9 is shown with a hexagonal cross-section. The cross section can also be round.

4 shows a cross section through the handle 1 and the cap 3 in the plane II-II of the locking device of the cap 3. The cams 17, projecting from ring land segments of the cap edge, engage in grooves 20 which are in the cavity 8, 13 of the handle 1 are formed. In the illustrated locking position transverse webs 24b are engaged in the grooves 20 in corresponding grooves 24a in the cam 17. To release the lock, a resistance must be overcome, which is caused by the fact that the ring land segments with the cams 17 must be compressed radially inwardly when the locking is to be overcome.

Fig. 5 shows a perspective view of the locking device 15 for fixing the cap 3 on the handle 1. At the edge of the cap, the cams 17 are formed, which dive when placing the cap 3 on the handle 1 in grooves 20 in the wall of the handle 1 are formed. By rotating the cap 3, the cams 17 are displaced into undercuts, so that the cap 3 is axially secured. In the cam 17 grooves 24 a are formed, engage in the transverse webs 24 b, when the cams 17 are displaced into the undercuts. When overcoming the transverse webs 24b, the cams 17 spring radially inwards. Therefore, a resistance must be overcome both when backing and when loosening the cap 3, which in particular should prevent unintentional loosening.

The plan view of the collar 6 of the magazine sleeve in Fig. 6 shows how the screwdriver bits 4 sit with the hexagonal shafts in the formed in the collar plate quivers 21, which are formed by the radially and circumferentially extending webs 22. The quiver 21 have only a small height and are partially open in the radial direction to the outside, so that the screwdriver inserts 4 can be easily removed or used again. The quivers 21 also serve as positioning aids,

In Fig. 7, the magazine sleeve 5 is shown with attached screwdriver inserts 4, the latter being held in accordance with the second embodiment of the holding device by axially oriented clamping spring elements 23 which are integrally formed on the magazine sleeve 5 and the collar 6, the spring elements 23 have in their height extension recesses 23a. In these recesses preferably engage the edges of the hexagonal shafts of the screwdriver inserts 4, while the side lips are bent, whereby a frictional connection is formed.

In Fig. 8, the holding device is shown in a side view. Instead of the axially oriented spring elements 23, it is also possible to provide those which are oriented radially and extend fan-like from the central part of the magazine sleeve 5 above the collar 6.

9 shows a longitudinal section through the magazine handle according to FIG. 1. In the embodiment according to FIG. 9, however, instead of the large ring magnet 7 fastened to the collar 6, a smaller ring magnet 7a is fastened to a shoulder of the magazine sleeve 5 in the direction of the cap , The screwdriver bits 4 lie with the shafts laterally on the sleeve-shaped magnet 7a and are held by the magnetic force.

In the embodiment shown in Fig. 10, a magazine sleeve 25 is provided which is integrally formed and made of a magnetic material. This has the advantage that no separate magnet 7, 7a is present, which must be attached to the magazine sleeve 25 as an additional component. Moreover, the screwdriver inserts 4 always sit securely in the magazine sleeve 25, because the inserts 4 are not only held on the bottom or side surface, but on both surfaces. The one-piece design of the magazine sleeve 25 is also significantly cheaper than a two-part design.

All components are kostenlg made of plastic by injection molding. The magazine sleeve 5 and the magazine core 9 can also be made of a magnetically non-active metal, for example aluminum, if a magnet 7.7a or spring elements 23 is used as the holding device. It is advantageous to produce the handle 1 with a core handle made of hard plastic and provided with a jacket 1a made of Welchkunststoff. As a result, on the one hand a more pleasant feeling in the handle 1 comprehensive hand generated, on the other hand higher torques can be transmitted to the handle 1, because soft plastic has a higher coefficient of friction than hard plastic.

Of course, in the magazine expediently screwdriver inserts of different types or sizes are classified in order to rotate with a mounting different screws. In the figures, the assembly is shown only by way of example with little different types.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways. It can be seen, however, that a magazine handle for receiving interchangeable tool inserts, in particular screwdriver inserts 4, has a handle 1, whose front part has a device for receiving a tool insert 4. The handle 1 also has a handle main body G. In this a coaxially arranged to the handle longitudinal axis A magazine M is formed concentrically to a centrally arranged in the magazine M Magazine core 9 a number of tool inserts 4 receives. The magazine core 9 is with a magazine M in the handle main body G under rotation releasably closing cap 3, which enables the removal or replacement of at least one tool insert 4 from the magazine M in a release position.
