Description

and DK 174887 B1

The present invention relates to a trailer for automobiles, preferably a single or multi-axle trailer, of the type comprising a flat bed, with parallel side walls, an upright front wall and an upright rear wall, and connected to a towing car. rod connection with coupling means for coupling to a towing vehicle, which side walls are formed by profiles comprising cavities in front of, or which have outlets for receiving the side edges of the load and are arranged for direct or indirect fastening of the axle device.

Such a trailer is described in detail in the German Gebrauchsmuster DE 295 09 410 Ul, and the main principles behind this are a trailer construction without an actual chassis, which is made superfluous by the trailer's load and any load thereon being carried by the trailer's longitudinal profile. built-up sides, in which the laden inserted into the above-mentioned outlet, and fastened to a received! let projecting projecting first angular flap which is a part of said side profiles, and which angular profile second angular flap is downwardly projecting parallel to the profile outer side and intended for fastening the shaft body. Said cavity for receiving the bottom plate can furthermore be provided by providing the inside of the side wall profiles with a longitudinal projecting tab parallel to the first angular tab of the angle profile. Said side profiles can, in order to minimize the tare weight of the trailer structure, advantageously consist of extruded profiles of aluminum, more specifically sea-resistant aluminum is used, whereby the side profiles have a good corrosion resistance.

Said profile-built sides have a substantially rectilinear inner side from the upper side of the base plate to the upper edge, and in order to obtain a sufficient rigidity and load-bearing capacity of the profiles, these have one or more integrated cavities, typically an upper cavity and a lower cavity. closed or partially closed projections on the outer sides of the side profiles. It is further known from the above-mentioned publication to provide the outside of the upper cavity with a downwardly projecting tab with a projection on the inside for attaching hooks on elastic lines for holding the cover, for example a tarpaulin on top of the trailer. Said tabs for attaching the hooks can also be constituted by a tab on the outside of the upright side wall itself. The structure of the front and back profiles is approximately identical to the structure of the 30 side profiles, however with the main difference that the front and back profiles do not comprise angular profiles in connection with the lower box profile.

However, the above-mentioned trailer type leaves a lot to be desired with regard to appropriate layout, which is considered here for options for accommodation, as well as various safety aspects.

The present invention has for its object to provide a trailer of the initially stated type which strikes significant improvements in terms of fitting possibilities and protection of the profiles against wear, compared to the known trailers of this type. '

Trailers are often used for transporting heavier objects, building materials etc., which during loading can scratch / damage the upward-facing side edges and edges, and leave sharp edges and protrusions in aluminum surfaces and edges that can grab clothes etc. during passage. and cause damage.

In order to protect said side edges and edges from damage, the upper casing profile of both the side profiles, front and back profiles near the upper side can be formed 15 with locking grooves on the outer sides for receiving and locking cooperating locking tabs on adjacent sides of the flaps of an inverted U-shaped fender of shock-absorbing, wear-resistant material, which U-shaped fender in its mounted position encloses the upper sides of said upper box profiles. This achieves effective protection of the upper sides of the trailer box in connection with unloading and loading, and the presence of the fenders will also encourage the use of the fender-protected upper sides for temporary support of a heavy load to be loaded on the trailer when changing lifting position. This will not be the case when loading trailers without top fenders, as the temporary repulsion of heavy loads, e.g. stones, tiles, etc. will cause scratching of the aluminum material. The presence of the fender thus has a derived, very positive working environment effect, as it thus invites to make the 25 necessary shifts of lifting position, which in many cases is necessary when loading heavy objects on the trailer.

The fender may advantageously be formed of a tough elastic plastic material, and a preferred material may be PEH.

For the sake of protection of various necessary statutory reflectors and marker lights, the downwardly projecting second tab of the angular profile may be retracted relative to the outer vertical line of the side box profile, and which retracted tab in its free end has a from the outside of the tab substantially perpendicularly projecting therefrom, extending throughout the profile length, the extent of which at least corresponds to the retraction in relation to said projection line. Hereby a cavity is obtained which serves for good protection of said reflectors and lamps which are placed in the retracted profile, as the outside of the casing profile and the projecting edge of the profile will protect against impact.

(

Traditionally, at least the tailgate of the trailer is foldable, and gradually the front bib of modern trailers is also foldable. Said front and rear bibs are usually fastened to the sides of the trailer by means of external traditional holding means in the form of fastening brackets, for example a handle which is rotatably mounted either on the front or rear bib, with a hook-shaped course at the opposite end which is intended for swinging into an eye attached to the end of the adjacent side of the trailer. This design carries the risk of the holding means gripping into unauthorized objects, and is therefore unfortunate. In addition, the corners of the trailer box are often angular, which can be unfortunate, for example if you bump into these.

The trailer's tailgate and any front bib may therefore advantageously comprise closure fittings if the operating means in the locked position of the closure bracket are phased into corner post profiles, and whose facing sides comprise U-profiles for receiving the rear front profile, respectively, and which closure brackets comprise facing sides of the attachment posts. the corner posts in the folded position of the bib.

This eliminates all risks related to protruding parts of the closing fittings while driving and engaging in unauthorized objects.

25

It is further realized by the invention that the corner portions of the trailer can advantageously be formed by upright hollow posts whose one side portion comprises a U-profile for receiving the ends of the side profiles, and which outer corners of the posts are rounded between the sides and the tailgate and are further formed with a recess for accommodating the abutment tabs. This ensures that the trailer has a completely smooth transition between corner posts and the front and rear bibs, respectively.

! 4 DK 174887 B1

The known trailers usually comprise lashing hooks located on the outside of the trailer sides, at the bottom, this may be inappropriate as distances between the object or objects to be fastened and the lashing point become too long, so it is realized by the invention that improved lashing possibilities are obtained by designing side profiles. at least one hole in the upper box profile, in which there are grooves for insertion and retention of a hollow rail inserted therein. This provides lashing options closer to the I or the objects on the trailer load that must be lashed during transport.

|

In order to provide such great freedom of choice with regard to lashing possibilities on the trailer according to the invention, the front and rear insides may also comprise at least one hole in the upper box profile, in which there are grooves for insertion and retention of a hollow rail inserted therein.

in

It should be noted that it is further realized by the invention that the lashing possibilities can be further increased by forming the insides of the side profiles with at least one hole in the lower box profile, in which there are grooves for insertion and holding of a hollow rail inserted therein.

In order to provide such greater freedom of choice with regard to lashing options on the trailer 20 according to the invention, the front and the inside of the back may also comprise at least one hole in the lower box profile, in which there are grooves for insertion and retention of a hollow rail inserted therein.

It will of course be possible to combine the design of the profiles with regard to achieving the ideal lashing possibilities.

In order to be able to obtain stable joints between side profiles / end profiles and corner posts, these joints can advantageously be constituted by a fastening element comprising a block of rigid material comprising a groove for receiving an inner tab in the hollow corner profile, thus that the block is in abutment against substantially the entire cross-section in an area substantially corresponding to the width of the first angle-bent part of a cooperating angle-bent joint piece in suitable rigid material, so that the block and the first angle-bent part are assembled with suitable means passed through holes arranged therefor , which collection- DK 5 DK 174887 B1; the second part of the piece is fastened inside the adjacent profile, with suitable means of assembly.

This results in a significantly better distribution of transverse force influences in the joint area, as the presence of the block distributes the forces over a considerably larger area than would have been the case if only ordinary rivet or bolt joints had been used.

Often there is a need to increase the wall height of a trailer, or there is a need to apply different accommodation on top of the trailer sides. These different types of equipment have so far been fitted in different ways, but common to these has been an impression of high instability.

However, it is realized by the invention that a stable assembly system for accommodation can be provided by a holding element of a substantially cylindrical body, for lowering into the hollow corner posts, which holding element consists of an upper part and a lower part, the upper part internally comprising a bearing for the head of a bolt extending therethrough which is | anchored in a threaded passage in the lower part, which upper side and lower part facing sides are cut at an angle, so that clamping at the bolt causes a mutual displacement of the center axes of the upper and lower part, and thus of the cross-sectional diameter of the holding element. Hereby it is achieved that the holding element by sufficient tightening by means of the bolt is fastened inside the corner post, by pressing against the inner side surfaces of the corner post, and with the upper part projecting above the upper edges of the side and end profiles.

20

It will then be possible to place e.g. raising all four sides of the trailer by frame, consisting of end profiles, provided with hollow corner profiles, and placing the frame on top of the existing trailer sides, by leading the hollow corner profiles down over the upright tops of the equipment holders anchored in the underlying hollow corner profiles. This will result in a very stable increase in the side sections of the trailer.

In order to provide a good abutment in the abutment surface between the rubber fender on the trailer box and the frame constituting the side elevation, the end profiles on the underside and preferably on the outwardly facing side are formed with a downwardly directed edge, which results in improved stability against compressive forces on the outside. The downward-facing edge also covers any gaps between the underside of the side elevation that may or may not give a false impression of instability.

6 DK 174887 B1

For protection of the upper sides and edges of the trailer side elevation, the end profiles are provided with a rubber fender similar to that found on the upper sides of the trailer.

It will be obvious that the holding elements can be used for attaching other fitting elements, as long as these comprise cavities for receiving the projecting upper part of the holding elements.

! In order to counteract wear between the top of the end posts of the corner posts and in the fitting elements, spacers in the form of shock-absorbing material placed between the corner posts profiles of the fitting elements and the corner profiles of the trailer can advantageously be used as accessories for the holding elements.

Without sacrificing other embodiments of the trailer according to the invention, it can be stated that the side walls can advantageously consist of profiles of extruded aluminum or of profile-bent metal sheets.

The invention is explained in more detail in the following with reference to the drawing, in which

FIG. 1 shows a trailer 2 according to the invention, with a bottom 4, as well as sides 6, front side 8, as well as a rear side 10, drawbar connection 12, coupling part 14 and wheels 16. Trailer sides are further provided with a side elevation 18.

The sides 6 are, as can be seen from fig. 2 built up of metal profiles, preferably of sea-resistant aluminum, which has a vertical side 20, on the outside of which 21 an upper box-shaped profile 22 and a lower box-shaped profile 24 are found.

The upper box-shaped profile comprises locking grooves 26 near the upper side 28 of the profile box, cf. fig. 4, 10 for accommodating cooperating hook-shaped locking tabs 30 on the tabs 34 of an inverted U-shaped fender 36 of shock-absorbing, durable material.

The outside 38 of the profile box 22 further has a projecting tab 40 for attaching hooks (not shown) to an elastic cord in a tarpaulin (not shown) to cover the trailer bed.

On the inside of the wall 20 there is a hole 42 with grooves 44, for receiving a hole rail 46 which is slid in from the ends of the profile, for use in lashing objects placed on the bottom plate 4 of the trailer, cf. fig. 6 and 7.

The lower box-shaped profile 24 is closed at the bottom by an angular profile 48, with a horizontal tab 50 carrying the bottom plate 4. The bottom plate 4 is further interposed between the tab 50 and a projecting clamping nose 52 on the inside wall 20. Hereby a good retention of the bottom plate 4. The vertical tab 54 of the angle profile is retracted relative to the outside 56 of the lower profile box, the tab 54 is further formed with a projecting edge 58 perpendicular to the tab. This creates a cavity 60 which is suitable for the protection of any necessary reflectors and marker illuminators (not shown).

In FIG. 3 shows a front or back profile 62, comprising a vertical side wall 20 and the same details in the upper box profile 22, for which reason with reference to these details reference is made to the above description of the device shown in fig. 2 shown side profile. As can be seen from FIG. 3, the lower box profile 64 of the front or rear profile 62 does not include an angular profile at the bottom, but includes a downwardly directed nose tab 66 flush with the outside of the lower box profile 68. The front and rear profiles 62 are further used to increase the side height of the trailer. * DK 174887 B1 8 pure 2, as is otherwise shown in detail in fig. 4. Here, the nose flap 66 serves as a stabilization against transverse forces on the side height increase 18. It is noted that the fender 36 also serves as a spacer between the two professional sides 28, 67, so that no abutment surfaces metal against metal occur.

5 I ftg. S shows a detail view of a corner profile 70, also of extruded sea-resistant aluminum. The corner profile 70 comprises a U-shaped profile 71 for receiving the adjacent side profile 6, and further comprises a rounding 72 of the outer corner part, as well as a recess 74 for receiving a contact tab 76 on the closing profile 78 with recessed closing mechanism (not shown). ), whose slidable locking bolt 80 is inserted into the corner profile via a socket 81 (cf. Fig. 8) in the recess 74 by folding up the back wall 10 and possibly the front wall 8, and is mounted in the socket 81, by sliding the locking bolt 80 by the actuating handle. With this construction, the advantage is obtained that the corners of the trailer do not appear as angular.

FIG. Fig. 6 shows an embodiment of the trailer provided with the lashing rails 46, and 7 shows how a lashing rail 46 is inserted into the grooves 44, and is displaced so as to cover the cavity 42 on the inside of the upper profile box 22 of the side profile.

FIG. 8 shows a detail of a preferred fastening element 82, comprising a block 84 with a groove 86 for receiving an inner tab 88 of a corner profile 70, so that the block abuts at least V * of the inner wall 90 of the corner profile in a width which at least corresponds to the width of the first angle-bent half 92 of a cooperating angle-bent joint piece 94. The block 84 and the first angle-bent part 92 are joined by 25 collecting means (not shown) passed through holes 96 provided therewith, so that the corner profile side 90 is clamped between the angle-bent part 92 and the block 84. Fastening of the corner profile with side profile 6 to the adjacent side takes place by suitable means of assembly (not shown) through corresponding holes 100 in the joint piece 94. The advantage of using the fastening element 82 is that with the block on the inner side 90 of the corner profile 70 30, a better distribution of transverse force influences in the joint area is obtained, as the forces are distributed over a considerable size e area than if the assembly was made with one or more rivets or bolts.

FIG. 9 shows a section of a corner of a trailer 2, where side elevation is to be made by placing side elevation elements 18 assembled into a box-shaped frame for placement on top of the upper edges of the sides 8. Fastening of the side elevation takes place by means of a holding element 102, which is formed by a cylindrical body 104 for lowering into the 5 hollow corner profiles 70. The holding element 102 is formed by an upper part 106 and a lower part 108.

t

The upper part 106 has an inner abutment 110 (cf. Fig. 10) for the head 112 of a bolt 114 extending through the abutment 110, which engages in a threaded hole 116 in the lower part 108.

The facing sides of the upper and lower part 106, 108 are obliquely cut, and a clamping of the bolt 114 by means of special tools passed down through the opening 118 in the upper part 106 will cause a mutual displacement of the center axes of the upper and lower part in (not shown) and thus an increase in the diameter of the circumscribed circle of the holding element.

Hereby it is achieved that the holding element 102 is fastened to the inside of the corner post 70 by sufficient tightening at the bolt I 114, by pressing against the inside of the corner post. pages, or protrusions on them. The holding element will thus appear with a part of the upper part 106, projecting over the sides 6,8,10.

It will then be possible to place a side elevation 18, in the form of a frame consisting of profiles 62, assembled with hollow corner profiles, by guiding the hollow corner profiles 70 down over the rising upper parts 106. The fender 36 ensures that the facing sides of the side -20 the elevation 18 and the sides 6, 8, 10 do not wear against each other like metal against metal. The side elevation also comprises fenders 36 similar to the sides 6, 8, 10, so that also the upper edges of the side elevation are protected against scratches etc.
