DETAILED DESCRIPTION
[0060]
[0061] In an unladen state as illustrated in
[0062] The cable pull system presently comprises two cable pulls 2L and 2R which each by way of a plurality of deflection elements, for example in the form of rotatably mounted cable pulleys or rigid deflection pieces, are deflected so as to transmit an adjusting force to the securing net 1. To this end, the cable pulls 2L and 2R are connected to one or a plurality of preferably electromotive drives which are not illustrated in
[0063] In order to be able to deposit an object G1 on the load surface L, the securing net 1 by way of the cable pulls 2L and 2R is lifted and adjusted to the loading position as illustrated in
[0064] Upon placing an object G1 on the load surface L and below the securing net 1, according to
[0065] The securing net 1 in the variant of embodiment illustrated is lifted and lowered by way of the cable pulls 2L and 2R merely in an erected state so as to secure a load on the load surface L. Consequently, the securing net 1 in particular does not have to be unwound from a wound roll or be repositioned along a roof-side longitudinal rail. In this manner, the entire load securing device is capable of being comfortably handled by a user and of being relatively readily assembled in the rearward load space of a vehicle, without massive interventions in the design of the load space having to be performed.
[0066] A second variant of embodiment of a load securing device according to the invention is illustrated in different views by way of
[0067]
[0068] As can be seen from
[0069] Parts of the adjusting mechanism of the load securing device having the two link chains 3L and 3R are illustrated in
[0070] The two guide tubes 6.1 and 6.2 presently run so as to be mutually parallel and transverse to a longitudinal axis of the vehicle. Each of the guide tubes 6.1 and 6.2 has an end portion that is bent by substantially 90°, by way of which a link chain 3L or 3R is deflected when being displaced out of the respective guide tube 6.1 or 6.2. A single electromotive drive 5 is provided for driving the link chains 3L and 3R in order for the latter to be deployed from their respective assigned guide tube 6.1 or 6.2 and to be retracted thereinto again. Said drive 5 is likewise preferably fixed to the lower side U of the load floor. The drive 5 drives a flexible drive traction means in the form of a Bowden cable 4 which in turn is operatively connected to both link chains 3L and 3R in order to adjust these relative to the guide tubes 6.1 and 6.2. The Bowden cable 4 herein has two Bowden sheaths 40 that each extend from the drive 5 to a Bowden support 9.1 or 9.2, a drive cable being displaceably guided within said Bowden sheaths 40. This drive cable, proceeding from the Bowden support 9.1 or 9.2, is deflected multiple times outside and along the guide tubes 6.1 and 6.2, such that both adjusting links 3L and 3R by way of the drive and of the Bowden cable 4 can be adjusted in a synchronous manner by activating the drive 5.
[0071] A plurality of deflecting and guide elements 7a to 7f are provided in the region of the guide tubes 6.1 and 6.2 for deflecting and guiding the drive cable of the Bowden cable 4. In order for as compact a construction as possible to be enabled herein, some of the deflection and guide elements 7a to 7f are disposed on holders H1 to H4 by way of which the guide tubes 6.1 and 6.2 are established on the lower side U. Thus, two deflection elements 7a and 7b, each configured as rotatably mounted cable pulleys, are provided on a holder H4 on mutually opposite sides of the guide tubes 6.1 and 6.2, such that the two guide tubes 6.1 and 6.2 in part extend between portions of the drive cable that run in a mutually parallel manner. Furthermore, two cable pulleys as guide elements 7c and 7d are disposed on two mutually opposite sides on a further holder H1 that is spaced apart from the holder H4 to the maximum, the drive cable being not deflected but merely longitudinally guided by said guide elements 7c and 7d. In order to achieve that the drive cable by way of one portion runs both parallel to the one guide tube 6.1 and by way of another portion runs parallel moreover the other guide tube 6.2, two guide elements 7e and 7f in the form of rotatably mounted cable pulleys by way of which the drive cable is deflected in total by 180° are provided. In this manner, the drive cable in the plan view runs in a substantially U-shaped manner about the two guide tubes 6.1 and 6.2 that are aligned so as to be mutually parallel.
[0072] Two drive elements in the form of slides 8.1 and 8.2 are disposed on the drive cable and are fixedly connected to the drive cable of the Bowden cable 4 such that these slides 8.1 and 8.2 are entrained by way of the drive 5 when the drive cable is displaced. The slides 8.1 and 8.2 herein each are repositionably guided on an external side of an assigned guide tube 6.1 or 6.2, so as to slide along a tube axis R of the respective guide tube 6.1 or 6.2 that runs in a rectilinear manner. A guide track for a slide 8.1 or 8.2 that runs longitudinally herein is defined by a lateral guide slot 60 on the respective guide tube 6.1 or 6.2. Each slide 8.1 and 8.2, through this guide slot 60, by way of a coupling element 80, for example in the form of a screw or of a bolt, is connected to a thrust link 303 that is repositionably mounted within the respective assigned guide tube 6.1 or 6.2. By way of the rigid connection between a slide 8.1 or 8.2 and the respectively associated thrust link 303, the thrust link 303 is conjointly adjusted by the slide 8.1 or 8.2 as soon as the drive cable of the Bowden cable 4 is displaced (cf. also
[0073] The partially deployed link chain 3L is illustrated in an exemplary manner in a fragmented manner together with a securing net 1 in
[0074] As can be seen in particular with a view to the sectional illustration of
[0075] The compression spring 302, the thrust link 303, and the force-transmission element 304 form a rear end of the link chain 3L or 3R that at all times remains within the guide tube 6.1 or 6.2. The link chain 3L or 3R is deployed out of the respective guide tube 6.1 or 6.2 and retracted thereinto by way of said end. The force-transmission element 304 herein is mounted so as to be longitudinally repositionable in the sleeve-shaped portion of the thrust link 302, wherein any adjustment in a longitudinal direction can only be performed counter to a restoring force that is applied by the compression spring 302. By way of the compression spring 302 that is supported on the thrust link 303 and on the force-transmission element 304 and is compressed during assembly, the chain links 31 of the link chain 3L or 3R are pretensioned in relation to one another in such a manner that the chain links 31 in the deployed state are fixed to one another and the securing net 1, by way of the chain portion that on account thereof is then rigid transversely to the deployment direction, can be held in a position above the load surface L.
[0076] In order for the pretension on the individual chain links 31 to be generated, a plurality of pretensioning cores 312a and 312b are provided. The latter each extend through a chain link guide duct 311 of a chain link 31, the former being radially spaced apart from the duct 31k for the core 301 but running parallel thereto. The chain links 31 are pretensioned in relation to one another by way of the pretensioning cores 312a and 312b which each engage at both ends of a link chain 3L or 3R. The preferably two or four provided pretensioning cores 312a and 312b thus each engage on the finisher piece 30 and on the force-transmission element 304.
[0077] By way of the connection of the pretensioning cores 312a and 312b to both the force-transmission element 304 as well as to the finisher piece 30, the force-transmission element 304 can thus be conjointly adjusted in the case of an adjustment of the thrust link 303. An adjusting movement of the thrust link 303 in the case of a link chain 3L or 3R being deployed is thus directly transmitted to the chain links 31 that are sequentially disposed in the deployment direction. Furthermore, by way of the pretensioning cores 312a, 312b that are connected to the force-transmission element 304 and to the finisher piece 30, the force-transmission element 304 is entrained by the finisher piece 30 when the link chain 3L or 3R is deployed. The force-transmission element 304, relative to the thrust link 303, is pushed away from the finisher piece 30 by way of the compression spring 302, such that the force-transmission element 304 causes the rigidifying mutual connection of the chain links 31 when the latter are deployed out of the guide tube 6.1, 6.2.
[0078] By contrast, when a link chain 3L or 3R is retracted, an adjusting movement of the thrust link 303 is transmitted by way of the compression spring 303 to the force-transmission element 304. The latter in turn by way of the pretensioning cores 312a, 312b entrains the finisher piece 30 such that the latter finally is available on or in the end of the guide tube 6.1, 6.2, and the link chain 3L or 3R is fully retracted. The pretensioning of the chain links 1 in relation to one another herein is chosen such that the chain links 31 are mutually released when the respective link chain 3L or 3R is retracted into the interior of the guide tube 6.1 or 6.2, and the previously rigid chain portion thus becomes flexible again and can be deflected within the guide tube 6.1 or 6.2.
[0079] As can also be seen with a view to the enlarged illustrations of
[0080] Further details to the (thrust) link chains 3L and 3R and of the respective associated guide tube 6.1 and 6.2 are visualized in detailed views by way of the
[0081] As a point of differentiation for example from the illustration in
[0082] The fastening part 61* is configured as a separate component and by way of the flange region 610* thereof is fixedly connected to the end of the guide tube 3L or 3R. In this manner, the production of the respective guide tube 6.1 and 6.2 is simplified, and the requirement of a deflection angle and of the guide track for the link chain 3L or 3R is variable by way of the use of different fastening parts 61*.
[0083] Moreover, an exemplary design embodiment of a finisher piece 30 at the free end of a link chain 3L or 3R is visualized in the enlarged illustration of
[0084] Of course, not only a planar flexible securing element in the form of a securing net 1 can be adjusted by way of the adjusting mechanism, having a link chain 3L or 3R or a plurality of link chains 3L and 3R, that is illustrated in
[0085] Moreover, instead of a single common drive 5 for a preferably synchronous adjustment of a plurality of link chains 3L and 3R, it can also be provided in a variant of embodiment that the link chains 3L and 3R are adjustable in a non-synchronous manner by way of a plurality of (at least two) preferably electromotive drives.
[0086] In one refinement it can furthermore be provided that at least one light emitting light element is provided on and/or in an adjusting part of the device such as the link chains 3L and 3R, in order to make the deployed part of the link chain 3L or 3R more visible to a user. Such a light element can be formed by an optical fiber, for example. In a variant of this type, the individual chain links 31 can also be produced from a light-conducting material, for example, or light-conducting lines can be embedded in individual chain links 31. A light emitting light means can be integrated in the chain links 31 of a link chain 3L or 3R in particular in such a manner, and can likewise be deployable.
[0087] A variant of a load securing device according to the invention is visualized in
[0088] In
[0089] Supplementing
[0090] In the case of the disposition illustrated of the cable pulls 2.1 and 2.2 as well as 2.3 and 2.4 that act as tensioning elements and the installation of the latter along the securing net 1, sequential tensioning can also be provided, in the case of which the securing net 1 by way of the one cable pull 2.1 and/or 2.3 is initially pulled in the direction of the rear seat HS, the load of the load surface L on account thereof being repositioned in the direction of the rear seat HS. Subsequently, pulling is effected by way of an (additional) drive on the other cable pull 2.2 and/or 2.4, the securing net 1 thus being contracted, such that the previously repositioned load in the form of an object G1, G2, or G3 is wrapped by the securing net 1 and in the assumed position is secured on the load surface L.
[0091] Of course, other elongate flexible traction means, for example tension belts, can also be provided instead of a cable pull 2.1, 2.2, 2.3, or 2.4. Furthermore, the U-shaped profile of a tensioning element or of an adjusting part along a planar flexible securing element can also be combined with an adjustment of the securing element by way of a link chain 3L or 3R, for example. For example, a cable pull 2.1-2.4 can be embodied as the core 301 of a link chain 3L, 3R, or by way of a connection eyelet 300 be connected to the core 301 of a link chain 3L, 3R.
