Description

WORKBENCH ARRANGEMENT FOR SKIPAPARATION

The present invention relates to a workbench arrangement, comprising a base structure and a support element connected to the base structure for fastening workpieces and / or work tools to be machined, in particular skis.

Workbenches, in particular portable workbenches, which can be transported, for example, disassembled or folded, are known and are used in a variety of ways. Such workbenches are also offered and used for the maintenance, preparation and preparation of sports equipment such as skis, bicycles, etc. Especially when working at home, the problem of pollution when working on the workbench is a very important problem. This problem occurs particularly when preparing skis. The dirt is particularly diverse and undesirable. When processing the edges, small metal chips accumulate that fall on the floor, stick to shoes, clothes etc. and are easily carried through the entire apartment. The situation is similar with the wax, which is typically pulled off the base with a blade after application. Even if you try to collect and dispose of the wax as soon as you pull it off, some of the wax that has been removed in layers falls to the floor and is relatively easy to get stuck there. In addition, occasional wax drips onto the floor when ironing on the wax. The dripped wax is very difficult to remove, especially on roughly structured surfaces. It is often helpful to provide a work surface, e.g. newspaper, etc., under the workbench. However, this can only solve the problem of dripping wax. However, this does not solve the problem of the metal chips and the falling off wax. The skis are typically fastened to the workbench with a clamping device during processing, so that it is practically impossible to provide a catchment device underneath the skis. Even workbenches that are specifically offered for ski preparation do not offer a solution to this problem. The locking devices for the skis stand in the way of the use of a fall arrester. To make matters worse, the skis in all of the clamping devices or workbenches used are arranged in regions above the workbench and in regions freely above the floor, so that it is not sufficient to cover the floor alone to at least catch the dripping wax, but both The floor and the workbench must be covered if contamination of the workbench is to be avoided.

Similar problems also arise in other work, where, for example, sports equipment other than skis or other workpieces or work equipment are to be attached to the workbench and at the same time the dirt which is to be collected is to be collected. The problem is particularly acute where a long length clamped object, such as skis, has to be processed, so that the dirt accumulates over a relatively long length and a collecting device for a long length is desirable.

A mounting stand for two-wheelers is known from DE 196 05 392 C2, in which a two-wheeler can be connected to a support element which projects relative to a base structure. This document does not indicate that dirt is collected.

Accordingly, it is the object of the present invention to provide a workbench and in particular a ski preparation workbench arrangement in which there is space for a catchment device under an object to be processed or a working device and in particular no carrying structure etc. is in the way.

According to the invention, this object is achieved in the above-described workbench arrangement with a basic structure and a carrier connected to it. geelement solved in that the support element is substantially horizontally projecting and connected to the base structure at a distance from it.

The basic structure itself can be a conventional workbench, for example. According to the invention, the support element is cantilevered and connected to this base structure at a distance from the base structure, so that it is possible to arrange a catchment device for the entire length of the object to be processed.

The support element is preferably cantilevered in a plan view of the workbench and spaced apart from the base structure. With such a design, the support element can be arranged lower relative to the base structure than in the case where, for example, the work surface of a workbench is arranged at a vertical distance above the base structure. The size of the distance in plan view from the base structure is dependent on various factors, for example spatial distribution of the contamination that occurs, intended position of attachment of the collecting device, size of the collecting device, etc. and should be so large that essentially all of the dirt that accumulates the basic structure can fall into the collecting device. The distance is, for example, between 5 cm and 30 cm, for example between 7 cm and approximately 25 cm, for example between 10 and 20 cm or approximately 12 to 15 cm.

The base structure is preferably substantially elongate in plan view, and further preferably the support element is arranged essentially parallel to the longitudinal direction of the base structure. In the event that the basic structure is a normal workbench, this arrangement is preferred solely because, in principle, you can then work in front of the workbench as you would without the additional support element connected. On the other hand, such an arrangement requires the relatively smallest space requirement.

The carrying element preferably essentially comprises a carrying bar. In particular, the material for the support element can have a rectangular cross section. The carrying element can, for example, be made from a tall material exist. For weight reasons, it may be convenient to use aluminum ^¬ material. In particular, a square tube can be used.

105 At least one crossbar is preferably provided with which the support element is connected to the base structure. The crossbar can be attached to a conventional workbench, for example, with a screw clamp. It is also possible to provide receptacles on the workbench or

110 in which the crossbar can be inserted, similar to the ladder described below as the basic structure. In general, the crossbar can be inserted into an opening provided on the base structure and fixed therein. It is also possible for the support element to be integral with one or more crossbars or cantilevered

To provide 115 fasteners.

A collecting device is preferably arranged below the support element and, in plan view, essentially next to the base structure. A corresponding collecting device can be made very simple. You can at -

120 can be designed, for example, in the form of an elongated trough, which is arranged under the base element and hung, for example. It is particularly favorable to arrange such a collecting element relatively just below the carrying element, preferably at a height which is above the average waist height of a person working on it. That way

125 on the one hand ensures the safe trapping of dirt. On the other hand, the person working on it has substantial unrestricted freedom of movement. The collecting element can also be arranged in the manner of a "hammock" under the carrying element. It may be advantageous to stiffen the edges of a corresponding collecting cloth, for example by

130 light fiberglass sticks, etc., such as those used to stiffen tents or sails, which are inserted into the appropriate guide pockets on the collecting cloth. The collecting cloth can be attached to such rods particularly easily, for example to the support element. Such a collecting cloth can also be rolled up very small, for example

135 stowed inside a hollow handle, etc. It is particularly favorable to fasten the collecting device with a quick attachment, for example by a snap fastening or by a tightly fitting or resilient fit, into which the fall arrester can be easily attached. It is expedient to attach the collecting device to the support element and / or to the crossbar and / or to the base structure.

At least two crossbars are preferably provided, and it is particularly preferred to connect the collecting device to the crossbars. 145 For example, the fall arrester can simply be attached to a crossbar at two points.

The working height of the carrying element is preferably adjustable. This can be accomplished, on the one hand, by the height of the support element being adjustable relative to the base structure, for example by a corresponding height adjustment of the connection to the base structure or a corresponding height adjustment between cross bars and support element, etc. It is also possible to base the structure train yourself height adjustable.

155 The support element is preferably removably connected to the base structure. For example, pipe plug connections can be used. Such connections can absorb relatively high forces and are nevertheless designed to be relatively simple. Clamping devices, e.g. Clamping screws can be provided to insert such pipe connections

160 pipe longitudinal direction to fix. It may be expedient to connect the carrying element in such a way that the collecting device can remain below the carrying element during the removal of the carrying element, so that dirt lying on the carrying element can be easily tilted into the collecting device and contamination does not occur during dismantling.

165 The carrying element itself can also be designed to be dismantled. For example, the support bar can consist of several pluggable elements.

The base structure can preferably be collapsed and / or dismantled. The 170 enables easy transportation and storage. The base structure is preferably a scissor-like frame with two legs connected to a swivel joint and a fixing mechanism with the aid of which the legs are fixed relative to one another in the erected state

175 and the support element is connected to the upper region of the legs. In general, this construction is reminiscent of the base of an ironing board. The upper ends of the legs can, for example, be rotatably connected to a horizontally arranged horizontal strut, one of the ends in the longitudinal direction at different positions of

180 the fixing mechanism can be fixed so that the frame can be adjusted to different working heights. The locking mechanism can simply be a clamping screw with which the upper end of the leg can be clamped or screwed in place at the corresponding position of the strut. A particularly simple construction and a particularly simple one

185 handling results if an axis extension is provided essentially at the position of the axes of rotation, it being particularly favorable to effect the actuation for the fixing mechanism, for example for the clamping screw, by turning one of these axes. The user can then grab the two handles from the folded state,

Pull 190 to the desired height and fix it at this height by actuating the locking mechanism. The two handles can also be designed so that they represent the crossbars for fastening the support element and thus create the necessary distance from the frame so that dirt can fall down without remaining on the frame.

195 A stand-up element is preferably provided on the base structure and in particular on the legs of the scissor-like frame, which protrudes downwards under the support element. In this way, a secure stand is implemented in terms of use if a force is applied downward in the region of the carrying element 200 in the direction of the floor.

The base structure is preferably a ladder which has two side strut arrangements which have a plurality of side strut elements which are pivotally connected to one another by joints, and a plurality of rungs, so that the 205 ladder in the form of a work platform with essentially horizontally arranged side strut elements and with essentially vertically arranged side strut elements serving as legs, wherein the removable support element is connected to the ladder set up to the work platform. Conductors, especially light conductors made of aluminum

210 um material, are produced in large quantities and sometimes very cheap. In particular, such conductors that are made of box-like hollow profiles are extremely light and yet have great strength. Such ladders also typically have a lot at the ladder ends between the side struts to which the individual ladder rungs are attached

215 wide support elements with rubber cover, so that such ladders can be set up very stably on the floor. These contact elements often protrude significantly over the ladder to the side, so that tipping to the side in particular is not easily feared. The ladders described, which can be set up in the manner of a work platform, also serve on the

220 horizontally arranged area arranged step plates, which are often made of aluminum material or sheet metal, typically as walk-in work platforms, for example for painting walls and ceilings, etc. Accordingly, such ladders set up in the form of a work platform are extremely stable and despite their very low weight own with the

225 very wide support elements already described have a very high lateral tilt stability. In addition, the joints of such ladders often have different latching positions in terms of angle, so that the working height can also be easily adjusted.

230 Preferably, at least one rung of the ladder is hollow and connected to the side strut elements in such a way that a through opening is formed by the side strut elements and the rung, and wherein the cross bars have a slightly smaller outer contour that fits into the inner contour of the through opening and that fits into the By-

235 aisle opening is inserted and fixed therein. In this way, a support element can be connected to the ladder extremely easily. The constellation described with a passage opening through rung and side strut elements is very often found in the light aluminum diverters. The long passage opening is ideal, the carry

240 element to connect in the manner described. Since the cross section of the through opening is typically essentially rectangular, matching cross bars can be provided relatively easily. If a load is essentially only in the longitudinal direction of the ladder set up as a platform or in the direction of the floor, it is not necessary to do so

245 To fix the crossbar in the passage opening of the ladder. On the other hand, it can be easily fixed, for example by a simple pin running transversely through the connecting rod and an associated contact surface on the opposite conductor end. Possibly. can provide resilient damping elements between the stop and the ladder

250 and / or be provided between the locking pin and the conductor. In this way, a positive locking of the crossbar can be carried out without any problems. Alternatively, for example, a frictional fixing can also be provided, for example by means of a conical transverse rod which is pushed in until it engages with the inner wall of the through-hole.

255 aisle opening comes in fixed system. Another possibility of frictional fixing is to move the crossbar or parts thereof outwards after the crossbar has been inserted into the through opening such that they come into contact with the inside diameter of the through opening. For example, there is the possibility of elastic compliance

260 areas to be provided in the crossbar, which bulge outwards for example by shortening the crossbar in the longitudinal direction and then come into contact with the through opening. It should be pointed out that in this way one and the same crossbar in through openings of different cross-sectional sizes - for example in the case of conductors of different sizes

265 manufacturers - can be positioned. It should be pointed out that the idea of using a commercially available ladder, which can be constructed in the form of a platform, as the basic structure of a workbench arrangement, is considered in itself to be inventive and in particular without the characterizing features of claim 1.

270 When preparing skis, it is often necessary to park the second ski or other skis that are not being worked on. To this Purpose, it is possible to provide a rack for storing such skis, for example on the side of the base structure opposite the support element. A rack frame can, for example, have storage elements arranged one above the other, which allow skis to be stored horizontally one above the other. The basic structure can also be provided with a horizontal shelf, for example a board, etc., which is used, for example, to store tools.

280 The base structure of the workbench arrangement is preferably a wall bracket. Using this wall bracket, the workbench arrangement can be attached to a wall. The carrying element is preferably detachably connected to the wall bracket or the base structure. The wall bracket can

285 can be designed, for example, like a shelf bracket into which shelf shelf supports can be hung. Similar to the shelf supports, the support element can also be hung on such a wall bracket. It is expedient to provide stiffening means in order to move the workbench arrangement in a direction essentially parallel to the wall surface at the outer end of the carrying element.

290 elements, ie in order to avoid that the outer end of the support element can move essentially parallel to the wall surface. For this purpose, a crosswise stiffening can be provided, for example.

The invention and refinements of the invention are explained in more detail below with reference to exemplary embodiments illustrated in the drawings. Show it:

325 FIG. 1 shows an exploded view of a workbench arrangement 2, having a base structure 4 and a support element 6, which is connected to the base structure 4 for use, for fastening workpieces to be machined. pieces, such as the skis 104 and / or working devices shown in FIG. 3, such as, for example, a woodturning machine.

The basic structure 4 shown is a scissor-like frame with two legs 10, 12 connected to a swivel joint 8. The legs 10, 12 are rotatably connected at their upper end to a horizontal strut 14. The rotary

335 point 16 of one leg 12 is firmly positioned on the horizontal strut 14. The pivot point 18 for the leg 10 can be displaced in the longitudinal direction, in particular through an elongated hole 20. A fixing mechanism 22 is provided in order to fix the pivot point 18 in the longitudinal direction of the horizontal strut 14. By changing the positioning of the pivot point 18 in the longitudinal direction of the horizontal

340 strut 14, a different working height can be set for the base structure 4. By moving the pivot point 18 all the way to the right in the illustration in FIG. 1, the scissor-like frame can be folded together, which allows easy storage.

345 It can be seen that the frame is essentially similar to the base of an ironing board. The legs 10, 12 have at their lower end support elements 24, 26, which each have feet 28 at their lateral ends, for example made of non-slip material such as rubber material. The individual legs, riot elements, struts of the base structure 14 are preferably made of one

350 metal material or other material of sufficient strength. Extruded aluminum profiles are particularly suitable because of their ratio of weight to stability. The upper ends of the legs 10, 12 are fork-shaped in the drawing, so that they encompass the horizontal strut 14 from both sides. You could also be cranked,

355 i.e. bend from the longitudinal direction of the legs 10, 12, similar to the design of the leg 10, which is cranked in the area of the pivot point 8, so that the frame can be folded as compactly as possible. It is also possible to connect the upper ends of the legs 10, 12 laterally next to the horizontal strut 14 at the pivot points 16 and 18.

360 The base structure 4 itself has an elongated shape which extends essentially in the longitudinal direction in plan view. Two crossbars 30 and 32 ra- gene from the horizontal strut 14 substantially perpendicular to the longitudinal direction of the base structure 4 away. In the embodiment shown, the

365 crossbars 30, 32 essentially extensions of the pivot, which form the pivot points 16, 18. The crossbar 30 can also be part of the fixing mechanism 22. The fixing mechanism 22 can have, for example, a sliding block which is provided with a thread and is arranged in the elongated hole 20. The pivot can be a corresponding one

370 have threads and be screwed into the thread of the sliding block. By tightening the pivot, i.e. In the embodiment of the crossbar 30 shown, the thread of the pivot is screwed into the thread of the sliding block and the sliding block is clamped against the elongated hole. In this way, the base structure 4 or the scissor-like frame in the

375 speaking height set. Instead of the locking mechanism 22 described, another clamping mechanism and / or locking mechanism can be used. In the simplest case, instead of the elongated hole 22, a plurality of bores are arranged essentially along a line in the longitudinal direction of the horizontal strut 14, with one pin each through the

380 forked upper end of each leg 10, 12 is pushed. In order to avoid collapsing while working, additional security can be provided.

The support element 6 can be connected to the crossbar 30, 32. The 385 crossbars 30, 32 create a sufficient distance from the actual base structure 4, so that a collecting device 34 can be connected underneath the support element 6 without problems over the entire length of the support element 6, for example without colliding with the legs 10, 12. This is made possible by the cantilevered arrangement of the support element 6 at a distance of 390 from the base structure. In particular, in the embodiment shown, the support element 6 is arranged at a distance laterally from the base element 4 in a plan view of the workbench arrangement 2. The lateral distance should be at least so large that a collecting device 34 can be connected in such a way that the essential dirt that accumulates is collected by this 395. In particular, the distance should be such that no or only little dirt can fall on parts of the base structure 4. In practice, a lateral distance of approx. 10 to 20 cm has proven itself.

In the embodiment shown, the collecting device 34 is a simple 400 cloth, which is suspended from the crossbars 30, 32 and is stretched just below it. The cloth or film of the collecting device preferably has a surface that is as dense and smooth as possible, so that wax dripping down cannot be sucked up and other dirt particles, for example metal chips, cannot adhere to it. This makes it particularly easy to dispose of the dirt and the collecting cloth can be easily kept clean. It is also possible to connect the collecting device 34 in such a way that it protrudes in the longitudinal direction forwards or backwards over the crossbars 30, 32. The catcher 34 can also be a stable tub e.g. be made of plastic material. It is understood that the 410 collecting device 34 does not necessarily have to be connected to the cross bars 30, 32. It is also possible to connect the collecting device 34 to its base structure 4 and / or the carrying element 6.

The support element 6 is arranged essentially parallel to the longitudinal direction of the base structure 4. It essentially has a support rod 36. Corresponding tubular receptacles 38 are provided on the support element 36 for fastening the support rod 36 to the cross rods 30, 32. The tubular receptacles 38 can be pushed over the crossbars 30, 32 and clamped with clamping screws 40. One or both 420 of the tubular receptacles 38 can be slidably attached in the longitudinal direction of the support rod 36 in order to participate in the movement of the cross rod 30 during the height adjustment. Alternatively, it is also possible to make the support rod 36 telescopic. It is also possible to form the crossbars 30, 32 integrally with the support bar 36 and to connect them releasably to the base structure 425. It can also be imagined to form the horizontal strut 14 of the base structure 4 integrally with the support rod 36 essentially at the position of the support rod 36, so that only the cross rod 30, 32 is connected to the upper ends of the legs 10, 12, while the pivot points 16, 18 and the locking device 32 on the support rod 36 430 are seen. In this way, a relatively large component of the base structure 4 can be saved with a slight loss of stability.

2 shows an alternative embodiment of a workbench arrangement 2, the base structure 4 being formed by a conductor 42. That is on the conductor 42

435 support element 6 connected. In this embodiment, the crossbars 30, 32 of the support element 6 are connected to the support rod 36. They can either be fixed or foldable, etc. on it. The ladder itself has two side strut arrangements 44, 46 which extend over the length of the ladder and which several can be pivoted together by means of joints 48

440 connected side strut elements 50. Rungs 54 are provided in the usual manner between the individual side strut elements 50. As can be seen in FIG. 2, the ladder in the form of a work platform with essentially horizontally arranged side strut elements 50 and with essentially vertically arranged side strut serving as legs

445 ben elements can be set up. Such a ladder 42 set up to the work platform is extremely stable and, in particular due to the relatively wide support elements 24, 26, also tilts sideways. This enables the lateral connection of the support element 6 to the ladder.

450 In the embodiment of FIG. 2, in addition to the support element 6, two rack frames 52 can be connected, on which, for example, skis that are not being processed can be placed. Typically, the rungs 54 of the conductors 42 are hollow and are further connected to the side strut elements 50 such that a through opening

455 56 is formed by the side strut elements 50 and the rung 54. This through opening 56 is suitable for connecting the carrying element 6 and the rack frames 52. It should be pointed out that a corresponding rack frame 52 can also be connected in the embodiment according to FIG. 1. In particular, the cross bars 30, 32 can be inserted into the

460 openings 56 can be inserted, whereby the support element 6 can be connected to the conductor 42. In addition, it is possible, for example by clamping or latching or pinning the support element 6 in Determine position relative to the conductor 42. The shelf racks 52 can be attached in a similar manner.

465 In the workbench arrangement 2 of the embodiment according to FIG. 2, a collecting device 34 can preferably also be connected. This can be carried out as described in connection with FIG. 1. It should be noted that the collecting device 34 is thus under the carrying

470 element 6 is arranged that the falling dirt is collected, i.e. ideally, the support rod 36 or the support element 6 is arranged substantially centrally above the collecting device 34. For this purpose, the cross bars 30, 32 in the embodiment shown in FIG. 2 can be extended in the direction to the right via the support bar 36, so that they essentially

475 symmetrical to the support bar 36 connection points for the collecting device 34 can be provided.

The catcher 34 itself has a width depending on the specific application. For example, it can be used to prepare skis

480 between 20 and 60 cm wide or between 30 and 60 cm wide or between 30 and 50 cm wide. As already mentioned, a wide variety of objects or tools to be processed can be arranged on the support element 6 of the workbench arrangement 2. The use of this workbench arrangement 2 for preparation is particularly preferred,

485 Care and maintenance of sports equipment, in particular skis and bicycles. The catcher 34 is also useful in applications where no dirt accumulates, for example when servicing sports equipment. Falling parts, for example screws, etc., are caught by the collecting device 34 in the same way as dirt.

490 The workbench arrangement according to the invention can be used with conventional ski clamping devices and preferably with a ski clamping device as described in WO 00/45908 A1. A ski tensioning device is described below, as can be connected to a 495 carrying element 6 with particular preference. FIG. 3 shows a ski tensioning device 102 for tightening a pair of skis 104 in pairs for processing ski edges 106. The Vorrich ^¬ tung has a pair of abutment surfaces 108 that on a Anlageflä-

500 chenelement 110 are arranged substantially opposite to each other. It can be seen that the contact surfaces 108 are arranged from the parallel position at a predetermined angle in such a way that the skis 104 are clamped against one another about their longitudinal axis 112. The angle is in the range of approximately 0 to 2 °, but can also be less or more.

505 In addition to the contact surfaces 108, a transverse stop 114 for positioning the skis 104 is arranged transversely to their longitudinal direction on the ski tensioning device 102. The cross stops 114 are located on both sides of the device 102 at substantially the same height, i.e. in a plane which, like the entire device, is essentially mirror-symmetrical to a symmetry

510 metry level 1 16 is provided in the longitudinal direction of the device 102 and going through the plane of symmetry 116. If there is talk of plane of symmetry 1 16 in the foregoing, it should be pointed out that symmetrically to this plane of symmetry 116 there are essentially the contact surfaces 108 as well as the transverse stops 1 14 and possibly longitudinal stops. Other elements

515 of the ski tensioning device 102, such as the tightening device etc., can be designed independently of the plane of symmetry 116.

In particular, it can be seen in the figure how a pair of skis 104 each lie on the ski tensioning device 102 with the covering 120 against a contact surface 108

520 is clamped. In this case, the edges 106 not to be machined in this clamping position bear against the first contact surfaces 114 at the bottom. It can also be seen that the contact surfaces 108 extend essentially over the entire width of the skis 104. For an optimal clamping of the skis, it would be optimal if the contact surfaces 108 extend over the entire width of the skis

525 104 extend. Then it is not possible to edit the covering side 222 of the edges themselves. With such a clamping, only the side wall side 24 of the edges 106 can be machined. Therefore, the contact surfaces 108 are not extended over the entire width of the skis 104, but end a certain distance in front of or below the edges 106 to be processed

530, the remaining free space should be so large that not only safe work of the entire base side 122 of the edges 106 is possible, but also that the tool 126 for processing the base side 122 of the ski edges 106 can be safely guided between the skis 104.

535 It can also be seen in the figure that a certain predetermined distance should be provided between the covering sides 122 of the edges 106 to be processed. This distance should not be too small, so that in the case of skis 104 which may be slightly incorrectly tightened, this does not result in excessive angular deviations in the mutually processed edges 106 compared to one another

540 leads. Geometrical considerations make it clear that the further away the edges 106 to be machined are from one another, deviations in the position of the skis 104 relative to one another result in correspondingly smaller angular errors, while very large angular errors then occur with a very small distance between them. In addition, tool 126 may be larger

545 distance between the edges 106 of the pair of skis be better guided against tipping.

FIG. 3 also shows the tool 126 for processing the base side 122 of the ski edge 16 of the ski 104 which is clamped on the left. The topping page machining

550 processing tool 126 has a clamping device 128 with a clamping block 130 and a locking device 132. In the case shown by way of example, the locking device 132 is a screw which can be used with a nut or a thread (not shown) for tightening the clamping block 130. A machining element 134 is replaced by the clamping device 128.

555 seibar and held essentially parallel to the plane of symmetry 116. It is pointed out that an angular arrangement of the processing element 134 in relation to the plane of symmetry 116 can be provided. The processing element 134 in the illustration shown is, for example, an abrasive paper. In successive steps

560, for example, sandpaper of different grain sizes can be used. Alternatively, a file or piece of file can be used. So-called "body files" can be used to remove a lot of material. The pad side processing tool 126 has two opposite edge areas 565 136, 138, the processing element 134 being provided on the edge area 138. A machining element can also be provided on both sides, so that only the tool has to be pressed against this edge in order to machine the opposite edge.
