Definitions

• the present invention relates to a device for fixing of elongate elements of cable/pipe type to a chassis of a veh icle, wh ich device comprises at least one elongate flexible first part configured to be passed rou nd and tightly hold said elements, and means configured to fix the first part and therefore said elements to the chassis, and a method for effecting such fixing .
• the invention is not confined to any specific type of vehicle and it is only by way of examples that wheeled motor vehicles such as trucks or buses, motor vehicles which move on caterpillar tracks, and trailers are cited .
• the elongate elements may for example take the form of cables to carry electric current or transmit signals, pipelines for water, hydrau lic liquid and the like.

• the invention it shou ld be noted that there are existing devices of the kind defined in the introduction for fixing of elongate elements in the form of cables and pipes to a truck chassis, in which devices said means comprise various kinds of brackets or the like wh ich are fastened to the chassis and to which said first part is fastened .
• brackets may in certai n cases take the form of a so-cal led cable ladder, and such brackets may for example be situated along the rear section of a truck chassis in order to lead cables and pipes along the chassis.
• the number of brackets which may be needed for said fixing may be relatively large , resu lting in not insig nificant weight and cost of such devices, normally one per bracket.
• Such brackets or the like may also at times obstruct other vehicle parts or their fu nctions.

• Th is object is achieved as regards the device by proposing a device of the kind with the features set out in the characterising part of claim 1 .
• Said means being provided with a second part configured to be inserted in a hole which ru ns through a section of the veh icle's chassis, and this second part being provided with means for fixing the first part to it, makes it possible for said elongate elements to be fixed to the veh icle chassis without using any brackets or the like, since the actual fixing is instead effected directly to said holed section of the chassis.
• Th is means that weig ht and costs may be saved wh ile at the same time enabling easy and qu ick fitti ng (fixing) of the elongate elements.
• said second part is configured to be compressible by wal ls of a said hole du ring insertion therein , in order to be locked in said hole via potential energy stored by the compression .
• said second part has portions wh ich participate in defining its external contour for insertion in a said hole and which are configured to be compressible by hole walls towards a centreline of said hole, with storage of potential energy.
• said portions to be for example tongue-like , spring-like elements which are forced inwards towards said centreline du ring the insertion of the second part in the hole and wh ich thereby store potential energy.
• Said second part may with advantage be made of plastic material .
• said second part has a head with a larger d iameter than a said hole into which the second part is configured to be inserted, and the head is configu red to serve as a stop device for the second part when the latter is locked in a said hole and to abut against chassis section portions su rrou nding said hole on the opposite side of said chassis section to the position of elongate elements held by the first part.
• the second part being thus configu red in such a way as to resemble a short bolt, and said head being used as an anchor, resu lts in an inexpensive si mple device which occupies little space when in use.
• the device has means configu red to respond to tightening of the first part rou nd said elements by automatically snapping into successive locking states as the first part is progressively tightened .
• the first part may have a striplike shape and may accordingly have a binding strap configuration with a plurality of transverse locki ng chambers following one another in its long itudi nal direction and defining said successive locking states. This makes it easy and quick to effect the fixing and securing of the elements tig htly to one another and to said chassis section .
• the first part is with advantage made of plastic material .
• the two parts mentioned are integral, one end of the elongate flexible first part being connected to the second part, making the device easier to handle .
• the second part has said means for snapping into correspond ing means of the first part during the insertion of the first part through an aperture in the second part, led by its free end .
• said two parts are separate items and the second part has portions for the first part to be threaded rou nd in order to fix it to the second part.
• the first part has said means for snapping into corresponding means on itself during the i nsertion of one end of the first part through the first- mentioned means during the formation of a loop surrou nding said elements.
• the first part is thus tig htened in a loop which is secured to the second part and therefore to the chassis section by being threaded rou nd portions of the second part, and the first part is locked to itself in a tig htened snapped-in state.
• said second part is configu red to be inserted in a hole in a frame of a vehicle chassis.

• the advantages of one version of such a method are ind icated with sufficient clarity by the above description of the device according to the invention .

• a device 1 for fixing of elongate elements of cable/pipe type to a chassis of a vehicle will now be described with simultaneous reference to Figs. 1 and 2.
• the device has an elongate flexible first part in the form of a strip 2 shaped like a binding strap with a plurality of transverse locking chambers 3 following one another in its longitudinal direction.
• the strip 2 is integral with a second part in the form of a pluglike part 4 by being connected to the latter at a first end 5.
• the pluglike part 4 is configured to be inserted in a hole which runs through a section of a vehicle chassis and to be lockable in the hole, and is accordingly configured to be compressible by walls of a said hole by being provided with portions 6 in the form of ridges which participate in defining its external contour for insertion in a said hole and which are configured to be compressible by hole walls towards a centreline of said hole, with storage of potential energy. Accordingly, these portions 6 of the pluglike part are made of plastic material which has this property, and the whole device 1 is here moulded as a single piece made of the same plastic material.
• the pluglike part 4 further has a head 7 with a larger diameter than a said hole into which the pluglike part is configured to be inserted.
• This head 7 is configured to serve as a stop device for the pluglike part when the latter is locked in a said hole and to abut, via surfaces 8 of the head, against chassis section portions which surround said hole on the opposite side of said chassis section to the position of elongate elements held by the strip 2 (see also Fig.4).
• the pluglike part 4 has means in the form of locking chambers 9 for snapping into corresponding means in the form of the locking chambers 3 of the strip 2 during the insertion of the strip 2 through an aperture 10 in the pluglike part, led by a free other end 11 of the strip. Accordingly, the pluglike part 4 has a hole 12 running through it to the head 7 via the aperture 10.
