Description

The invention relates to a load carrier for a jack with a stand column that can be placed on the floor, this is attached to a first transverse axis, two side walls having support arm, one of pivoting the support arm Serving threaded spindle, for those in the area of the upper Stand column end a first axial bearing and on the support arm in the Distance from the first transverse axis a second thrust bearing is provided, as well as with a hand crank on the column side End of the threaded spindle, the one on a body attachable load carriers in its lower area each side a storage approach for storing the Load carrier in openings in the support arm side walls such that the load carrier relative to the support arm about a to the first transverse axis parallel second transverse axis is pivotable, and a Channel for the passage of the threaded spindle and for the controlled Swiveling the load carrier around by the threaded spindle has the second transverse axis.

Such a jack is in EP-0 340 551-B1 the E.A. Storz GmbH & Co. KG described in detail and illustrated and the content of this document should also be the subject of the present Scripture.

Under a load carrier is the one above and below Part or that assembly of the jack understood which or which are attached to the vehicle body the lifting load and this in the support arm of the jack initiates.

The load carrier of the jack according to EP-0 340 551-B1 is specially designed for use on vehicles whose Body in those areas where the jack should be applied with one in the longitudinal direction of the vehicle extending and pointing downward web is, namely the so-called sill seam web. Therefore points the load carrier of this jack in its upper area a groove, which opens upwards, from the Top of the load carrier extends down and for the Recording of the sill seam web is provided. Using This well-known jack is therefore also suitable for Handling inexperienced people, of course, how to position the jack on the vehicle body, namely so that the sill seam engages in said groove.

However, the present invention is concerned with jacks of another type, namely those whose load carriers are from below against a seamless body attachment area is, and in such a case one can handle jacks Inexperienced person easily lift the jack in a wrong way Starting position, which then involves the risk brings that jack when lifting the vehicle slips away and / or the vehicle body is damaged. At such jacks, the top of the load carrier is more or less educated, at least when looking at the Load carrier in the direction of the second transverse axis, d. H. in the direction the axis around which the load carrier is lifted of the vehicle pivoted relative to the jack arm or in a direction perpendicular to this.

In the case of jacks to be used in the area of a sill seam web, whose load carriers have a groove for inserting the sill seam web it is relatively unproblematic if the one to be supported by the jack load carrier Body area and the one to be placed against this body area Top of the load carrier when placing the jack and / or relative to each other in the course of the lifting process are or are tilted (in the vehicle longitudinal direction or in Direction of the cross axles of the jack) because thanks engaging the sill seam web in the load carrier groove slipping of the load carrier is excluded. Such Slip protection is however with jacks with a Load carrier, the top of which can be placed against a seamless Body attachment area is designed, not given, so that with such jacks it is crucial that they are properly lifted to the body of the Vehicle.

The E.A. Storz GmbH & Co. KG now has a jack of the type mentioned in the introduction, in which the load carrier one with the bearing approaches for one pivotable mounting of the load carrier on the support arm, as well as with the channel for the passage of the threaded spindle Lower part and one that can be placed against the body from below Has upper part, which with the load carrier lower part one parallel to the second transverse axis and above the latter extending third transverse axis is pivotally connected. In this known jack are the top and bottom of the Load carrier pivotally connected to each other via two joints, the hinge axes coinciding with the third transverse axis and each joint has one attached to the lower part of the load carrier and from this laterally protruding journal as well as a bearing cheek arranged on the side of the upper part of the load carrier with a bearing opening for snapping onto the relevant one Has bearing journal. The load carrier upper part including the two bearing cheeks and the lower part of the load carrier together with the both journals are each made as one-piece plastic injection molded parts designed, and that in the two cheeks The storage openings provided are designed as open at the bottom Openings formed, in such a way that the Load carrier upper part from above onto the load carrier lower part can snap on, with elastic expansion of the extending downward from the actual storage openings Slits of the bearing cheeks; after snapping on the The upper part of the load carrier is the bearing journal of the lower part of the load carrier in said storage openings. Upper and lower part of the load carrier are provided with stops which the Swiveling of the upper part of the load carrier in relation to the lower part of the load carrier limit, d. H. two end positions of the Define the upper part of the load carrier. The top of the load carrier top is for placing against a seamless body attachment area designed, d. H. the load carrier upper part does not have a groove for inserting a sill seam web. Between the upper part of the load carrier and the lower part of the load carrier a steel wire spring is arranged, through which the unloaded Load carrier top always in that of his two End positions is pivoted in when the jack is on the body of the vehicle to be lifted is attached, However, the top of the load carrier upper part is not yet loaded (seen in the direction of its pivot axis) with the Axis of the jack screw spindle is relatively forms a small angle, the tip of which is towards the crank handle Threaded spindle end has - this angle is approximately 15 °. This ensures that the top of the still unloaded upper part of the load carrier when attaching the Jack at least approximately parallel to the body attachment area runs if a defective impeller (with flat foot) should be replaced while changing the vehicle as described in such cases often occur, relatively heavily loaded is, which should be noted in this context must that a jack is always for a very specific vehicle is constructed. Broken tires come however these days hardly ever before, so the most common case of use a jack changing a wheel during the transition from summer tires on winter tires or vice versa, and then takes place the wheel change of course when the vehicle is not loaded. For but this case has been caused by the spring and inclination of the upper part of the load carrier defined by the stops of the well-known car jack proved to be unfavorable because the so inclined load carrier upper part the user of the jack tempted to set the jack wrong, so that he can slip when lifting the vehicle. It also has It has been shown that the load carrier upper part in this known jack Disengage on one or even both journals can if the load carrier one-sided in the course of the lifting process which is never completely excluded can be - since the jack is always in the neighborhood of the wheel to be replaced is the vehicle body not only around the vehicle's longitudinal axis during the lifting process tilted, but also around the vehicle's transverse axis.

The invention was based on the object of this known Jack from E.A. Storz GmbH & Co. KG to improve that at least one of the two shown above Risks can be avoided.

Starting from a load carrier of the type mentioned at the beginning, which one with the storage approaches for storage on Support arm and with the channel for the passage of the threaded spindle provided lower part and a from below against the Has body attachable upper part, which with the Load carrier lower part via two joints around one to the second Transverse axis parallel and above the latter third transverse axis is pivotally connected, the hinge axes coincide with the third transverse axis and each Articulated one attached to a load carrier part and from this laterally protruding bearing journal and one on the other Load carrier part with a side cheek Has bearing opening for snapping onto the journal, lets according to the invention there is a risk of the load carrier upper parts disengaging thereby avoid that the bearing cheeks in Direction of the articulated axes and their elastic Bearing openings are designed as openings with a closed edge are and that the trunnions and / or the bearing cheeks at their free ends with such inclined to the hinge axis End faces or inner surfaces are provided that the bearing openings with elastic deflection of the Snap the bearing cheeks onto the bearing journals. Different to in the known jack described above E.A. Storz GmbH & Co. KG can then create one in the course of One-sided loading of the load carrier upper parts occurs during the lifting process do not cause one of the bearing openings and the associated bearing journal (transverse to the axial direction of the bearing journal) be separated from each other.

In principle, it would be possible to mount the bearing cheeks on the lower part of the load carrier and attach the journals to the upper part of the load carrier, so that the upper part of the load carrier is the lower part of the load carrier overlapping laterally from above, it is more advantageous to design the construction so that the bearing cheeks are attached to the upper part of the load carrier and as a result those defined by the journal end faces Levels run up to each other to the load carrier top to be able to snap on from above.

The invention also proposes a solution to the problem that the user of the jack due to the inclination of the Top of the one in its end position Load carrier upper part is tempted to the jack incorrectly set (so that it can slip off) if at intact wheels and unladen vehicle a wheel to be replaced.

Starting from a jack of the type mentioned at the beginning, whose load carrier one with the storage approaches for storage on the support arm and the channel for the passage of the threaded spindle provided lower part and a from below against the Has body attachable upper part, which with the Load carrier lower part around a parallel to the second transverse axis as well as the third transverse axis running above the latter is pivotally connected and pivoted between two end positions can be, as well as with a between load carrier upper part and load carrier lower part arranged spring for Swiveling or holding the unloaded upper part of the load carrier this can be in an initial position or an upper part Solve the problem according to the invention in that the spring is designed that the upper part starting position between the two end positions of the upper part of the load carrier and as a result, the top of the unloaded load carrier upper part a lower incline when the jack is applied has than in the known above Jack from E.A. Storz GmbH & Co. KG - in particular then the inclination of the top of the load carrier upper part with respect to the axis of that provided in the lower part of the load carrier Channel only be a maximum of approx. 13 °.

Embodiments are preferred in which in the starting position the top of the load carrier its top - in Direction of the third transverse axis or seen perpendicular to it - one with the axis of the channel of the lower part of the load carrier such angle forms that when putting on the not yet loaded Load carrier upper part against the body attachment area an unloaded vehicle with intact wheels the top of the load carrier top approximately parallel to Body attachment area runs.

In the known jack described above E.A. As already mentioned, Storz GmbH & Co. KG exists the spring acting on the upper part of the load carrier Steel wire, it is between the upper part of the load carrier and - Lower part inserted and bent so that it is under cannot detach from the load carrier under normal circumstances. If so for example, the top part of the load carrier as a stamped and bent part made of sheet steel could be one Steel wire spring undesirable when the vehicle is moving Rattling noises in the trunk receiving the jack to lead. The spring is therefore proposed according to the invention to design as plastic leather, which is also the possibility of Achieving another advantage opened: With the known Jack from E.A. Storz GmbH & Co. KG must Steel wire spring manufactured and assembled as a separate part become; According to the invention, the spring is now proposed to form one of the load carrier parts and this load carrier part to be designed as a plastic injection molded part. Then can neither the described rattling noises occur, nor does it have to the spring is manufactured and assembled separately; Moreover the spring is attached absolutely captive.

Basically, it would be if both were designed accordingly Load carrier parts and the spring possible with a single Spring to get the unloaded load carrier upper part in its starting position between its two end positions to keep. Functionally more reliable and easier to manufacture however, are embodiments with two each other opposite swiveling movements of the upper part of the load carrier effecting springs, which are designed and arranged so that the unloaded upper part of the load carrier with respect to the lower part of the load carrier his for attaching the jack ideal starting position.

In this case, one of the two springs could be on one Load carrier part and the other spring on the other load carrier part be provided for manufacturing and assembly reasons however, prefer embodiments where both Springs are attached to the same load carrier part.

The spring or springs could be bow-shaped and fixed on both sides to one of the load carrier parts be, especially with regard to the manufacture of the Load carrier, however, it is more advantageous if each spring than a one-sided spring tongue is formed, which - in the top view of the load carrier - across Pivot axis of the upper part of the load carrier extends.

In embodiments with two designed as spring tongues Springs are recommended in embodiments in which both Springs are attached to the lower part of the load carrier and at least with the load carrier top part unloaded against its underside issue. This not only has manufacturing and assembly advantages, but also leads to a particularly stable starting position of the upper part of the load carrier. The latter applies especially for embodiments in which the two springs - in Seen in the direction of the pivot axis of the upper part of the load carrier - form a flat, upward opening V, in particular then when the two springs - towards this Seen pivot axis - approximately from the circumference of the bearing pins stretch tangentially.

If only made use of that part of the invention should be, by an optimal alignment of the top of the upper part of the load carrier is guaranteed the linkage of the upper part of the load carrier to the lower part of the load carrier effecting journal by a single, continuous Bolts can be replaced or by two pin-like Parts, which in the bearing openings of a load carrier part and one through hole or two blind holes in the other Load carrier part used and by press fit on one Load carrier part are held.

Finally, for the sake of completeness, it should be mentioned that a jack of the type mentioned with a two-part Load carrier, the upper part of which can be pivoted on the lower part of the load carrier is articulated from DE-196 25 281-A1 E.A. Storz GmbH & Co. KG emerges; just like that Vehicle jack according to EP-0 340 551-B1 also relates to the DE-196 25 281-A1 expressly only includes jacks for Start in the area of a sill seam so that the swiveling load carrier upper part an opening upwards Has groove for the engagement of the sill seam web.

Other features, advantages and details of the invention will be apparent itself from the following description and the attached graphic representation of a particularly advantageous Embodiment of the load carrier according to the invention.

In the attached Fig. 1, however, is first of all known car jacks resulting from EP-0 340 551-B1, to the basic structure of such jacks explain for which the load carrier according to the invention is provided is; Fig. 1 shows such a jack in one Side view and in a state after the support arm has already been swung up over part of its stroke.

The known jack shown in Fig. 1 is intended in the following can only be described to the extent that this is for understanding the basic structure and the function of such Jack is required for which the invention Load carrier is provided.

The jack shown in Fig. 1 has a pedestal 10, a support arm 12, a load carrier 14, a threaded spindle 16, a hinged to this crank 20 and one attached to the lower end of the pedestal 10, angled Base plate 22 on. The pedestal 10 consists of a Cross section of U-shaped sheet metal profile with two side walls 24 and a rear wall connecting them. Also with the support arm 12 is a U-shaped cross section Sheet metal profile with two side walls 28 and a connecting these Bottom 30, which is slightly narrower than the rear wall 26 the column 10 so that the support arm 12 with its according to FIG. 1 right end between the side walls 24 of the pillar engage and by means of a bolt 34 in the side walls 24 can be pivoted. The bolt 34 defines thus the first transverse axis in the sense of the claims.

In Fig. 1, an area of the front bracket side wall 28 broken away to show better how the Load carrier 14 is mounted on the support arm 12.

The load carrier 14 (like the one to be described later load carrier according to the invention) preferably from a plastic manufactured under the registered Trademark DELRIN is available on the market, or from a plastic with similar properties. Different from that load carrier according to the invention to be described has the in Fig. 1 shown load carrier 14 an opening upwards Groove 36 for receiving a sill seam web of the body of the vehicle which is connected to the jack according to FIG. 1 should be raised; the one to be placed against the underside of the body and the lifting load-bearing top of the load carrier 14 was designated 38.

On the load carrier 14 are on both sides (according to FIG. 1 in front and rear) molded bearing-like bearing lugs 40, the between their end faces and the side surfaces of the actual body of the load carrier 14 each have a groove 42 have; the bearing surfaces forming engage in these grooves Edges of bearing openings 44 in the side walls 28 of the support arm 12 a. In the same way, one of a plastic body formed nut 46 for the threaded spindle 18 on upper end of the pedestal 10 pivotally mounted; to this Purpose are on the actual body of the mother 46 on both sides Articulated pin 48 formed between its end faces and grooves 50 on the side surfaces of the actual plastic body form into which the edges of bearing openings 52 in the Intervene side walls 24 of the column 10.

The load carrier 14 has a possibly graded Channel 56 with smooth wall for the passage of the threaded spindle 16, while in the nut 46 a channel 58 with a Nut thread for the threaded spindle 16 is formed.

The left end of the threaded spindle 16 according to FIG. 1 is one mushroom-shaped head 60 formed between the and the load carrier 14, an axial bearing 62 designed as a roller bearing is arranged is.

The bearing lugs 40 of the load carrier 14 or the bearing openings Define 44 in the support arm side walls 28 the second transverse axis in the sense of the appended claims.

2 shows the preferred embodiment of the invention Load carrier 70 in a side view accordingly the representation of the load carrier 14 in Fig. 1. The load carrier 70 consists essentially of a lower part of the load carrier 72 and a load carrier upper part 74, which is articulated are interconnected. As can be seen above all from the figures 3, 6 and 7 results are on the body of the load carrier lower part 72 molded on both sides of the bearing lugs, which have a disk-like end plate 76a and between this and the actual body of the lower part of the load carrier 72 each form a part-circular groove 76b. In these grooves can the edges of the bearing openings 44 of the in Fig. 1 shown support arm 12, where then, if necessary the bottom of the two grooves 76b each have a bearing surface forms for the edge of one of the bearing openings 44. At a particularly advantageous and shown in Figures 2 and 3 Embodiment of the load carrier according to the invention 70, however, is on the underside of the load carrier lower part 72 a bow-like sheet steel part 78 attached, which is part-circular Bearing shell segments 78a forms in the Engage grooves 76b and in turn each a part-circular Form groove 78b; in this case it is part-circular Due to the two grooves 78b each have a bearing surface for the edges of the bearing openings 44 of the in Fig. 1st support arm shown 12. Define the grooves 76b and 78b a pivot axis 76c, which is the second transverse axis acts within the meaning of the appended claims.

Like the load carrier 14 of the jack shown in FIG. 1 with the channel 56 for the passage of the threaded spindle 16 is provided, the lower part 72 of the invention Load carrier 70 a channel 80 crossing the lower part on.

The lower part of the load carrier is above the bearing lugs 76 72 provided on both sides with a bearing pin 82, the Front in its upper area an oblique face 82a forms, the inclined end faces of these of the two trunnions 82 defined planes obliquely upwards to run towards each other to create sliding surfaces for the from above load carrier upper part to be snapped onto the load carrier lower part 72 74 form, as described in more detail later will be.

As can be seen in FIGS. 3 - 5 and 6, the load carrier lower part designed as a plastic injection molded part 72 injection molded two spring tongues 84 and 86 according to the invention; these spring tongues are on the top of the lower part of the load carrier provided and to be discussed later Way specially designed and oriented. At this It should only be pointed out that these spring tongues transverse to one of the coaxial journals 82 defined pivot axis 88, which is the third Cross axis in the sense of the appended claims. The Figures 4 and 5 show the two spring tongues 84, 86 in the unloaded Condition and also show that the spring tongues are inclined differently in this state and - viewed in the direction of the pivot axis 88 - approximately Extend tangentially from the circumference of the trunnion, namely roughly in opposite directions.

The load carrier upper part 74 shown in FIGS. 8-14 is provided on both sides with a bearing cheek 90, which a circular bearing openings 90a for storing the upper part of the load carrier 74 on the two journals 82 of the lower part of the load carrier 72 has. In Figures 8-14 is also the pivot axis 88 indicated. Although it is also as Plastic injection molded part manufactured load carrier upper part 74 is heavily ribbed, it forms - in the direction of the swivel axis 88 seen - a substantially flat top 92 as well flat underside areas 94, all in one to the top 92 parallel plane. According to the invention Bearing cheeks 90 can be deflected elastically (in the direction of the swivel axis 88), although with considerable effort Forces - the bearing cheeks 90 must be so dimensionally stable that the lifting force to be absorbed by the load carrier upper part 74 over the bearing cheeks 90 into the bearing journal 82 of the lower part of the load carrier 72 can initiate.

Rib-shaped regions of the lower part 72 of the load carrier form whose top stops 100, which correspond to the direction of the Axis of the channel 80 is relatively small form an acute angle α, which is in particular about 15 °. Underside areas act with these stops 100 94 of the load carrier upper part 74 together to the pivoting of the upper part of the load carrier compared to the lower part of the load carrier limit in both directions and thus end positions of the Define load carrier upper part 74.

On the other hand, the spring tongues 84 and 86 are arranged that these also with underside areas 94 of the load carrier upper part 74 cooperate, d. H. against such underside areas 94 rest, according to the invention the two spring tongues 84 and 86 are designed, designed and arranged so that when the load carrier upper part 74 is unloaded, the upper side thereof 92 with the direction of the axis of the channel 80 an angle β forms, which is smaller than the angle α and preferably is approximately 13 °. 2 shows the load carrier upper part 74 in an unloaded state, d. H. in its starting position, and also shows the angle β. It is now understandable which is why the spring tongues 84 and 86 are different are inclined.

Articulated around load carrier upper part 74 and load carrier lower part 72 To connect with each other, the load carrier upper part from above onto the lower part of the load carrier and towards pressed down; the bearing cheeks 90 slide onto the inclined end faces 82a of the journal 82 and are thereby elastically deflected in the sense of widening outwards, until the bearing pins 82 in the bearing openings 90a of the Snap the upper part of the load carrier 74 into place, as shown in FIG. 2 is.

In the load carrier 70 according to the invention, those of the Spring tongues 84 and 86 springs formed captive on Load carrier arranged, and by appropriate choice of Spring positions and spring forces can be any Bring the starting position of the load carrier upper part 74 to so as to ensure that when the jack is applied the Upper side 92 of the load carrier upper part 74 at least approximately runs parallel to that body area against which the load carrier is to be put on from below.

It is also considered to be within the scope of the present invention to consider, the claimed and described load carrier at least in one of the ways described below modify:

After the load carrier over a swiveling load carrier upper part the lower part of the load carrier on the support arm could also fixed, but in any case be attached so that it cannot be pivoted; therefore the lower part of the load carrier does not necessarily have to go with it Storage approaches and / or with a channel for passage the threaded spindle.

In principle, those provided on a load carrier part could Bearing cheeks spread with a suitable tool be so that on an oblique course of the journal end faces could be dispensed with.

After all, it would also be possible instead of sloping faces to be provided on the bearing journals, the inside of the bearing cheeks bevel accordingly to make it easy to snap on of one load carrier part to the other load carrier part enable.
