Luggage holder with suspension type crossbeam

The present invention relates to a crossbeam that is adapted to be mounted within the luggage holder of automobile-exterior face, especially hard-wired crossbeam, this crossbeam have formed the suspension type carrying support of luggage bracket.

For a long time, people use the luggage holder that is installed in the automobile-exterior face to transport the luggage that is placed on automobile external.The simplest form of luggage bracket is to be made of one group of parallel strip of installing with automobile top with flushing, and these laths are in order to provide additional support to prevent the damage of roof.Yet these supports lack the device that retrains luggage, usually cause losing of luggage when luggage skids off support.

In order to overcome this shortcoming, added the high framework of frame preventing that luggage is owing to the change of momentum skids off carriage.Framework generally is that the lath periphery along supporting luggage extends, and with being installed in pillar supporting on the roof on the surface that exceeds automobile.Though provide the constraint of supporting to main article, found that heavier goods causes supporting slat and the bending of roof by gravity easily.And, because the weight and the aerodynamic requirement of automobile do not wish to adopt heavier material manufacture support.

As a result, develop the support of raising that does not rely on vehicle roof supports, and because these luggage brackets can assemble, this manufacturing and erected cost have just been reduced before installing.Yet these existing high support both lacked necessary perimeter constraint, again crossbeam used heavy connecting device.Because the basic goal of any automobile design is will produce the automobile of aerodynamic requirement as far as possible to eliminate resistance.Because these connecting devices have increased air-flow resistance and this target of out of reach on the key position of vehicle structure.

The present invention be a kind of luggage bracket improvement the crossbeam assembly set, it has overcome the shortcoming of the luggage holder of prior art.

This crossbeam of design-calculated is to be used for constituting a fixing carrying support that hangs on the luggage bracket week frame according to the present invention.All frames of luggage bracket are adapted to be mounted within car surface, and the high certain distance of relative car surface frame.Crossbeam of the present invention comprises that has having of cross section ovalize beam member upper and lower surface, elongated.Be used for 〈 ﹠﹠ connecting device on the side bar is installed on each termination of beam member.Attaching parts has the flat substantially body of a band U-shaped root edge and straight apical margin.Be provided with an inside projection at the root edge place near attaching parts, it is inserted and secured in the hollow end of beam member.

The structure of the profile of attaching parts and inside projection all is in order to reduce the framework side bar and to hang the air-flow resistance that attaching parts produced between the crossbeam and design-calculated.So when beam member is connected on the attaching parts, will align with the lower surface of beam member in the U-shaped base of attaching parts.Equally, when crossbeam was connected on the side bar, the upper limb of attaching parts will align with the upper limb of side bar.In addition, making a call to a through hole, be used for crossbeam is fixed on mounting screw on the framework so that pass near the upper limb place of attaching parts.

Other purpose of the present invention, characteristics and advantage will be hereinafter show in conjunction with the accompanying drawings the detailed description.

The detailed description that most preferred embodiment of the present invention is carried out in conjunction with the accompanying drawings can have more fully the present invention and understand, and identical in the drawings parts adopt identical label.Wherein:

Fig. 1 is mounted in the transparent view that car surface has embodied of the present invention high luggage bracket.

Fig. 2 is the decomposition diagram before the present invention assembles.

Fig. 3 is a section-drawing of the present invention.

At first referring to Fig. 1, represent that luggage bracket 10 of the present invention is installed on the outside face 12 of automobile to support and transportation luggage or similar goods.What show in this most preferred embodiment is that luggage bracket 10 is contained on the automobile top.But this is applicable to that also luggage holder is installed on the bonnet, and luggage bracket 10 generally includes a framework 14 that becomes rectangle substantially.This framework is bearing on the car surface 12 with certain spatial relationship with a plurality of supporting seats 16, framework 14 comprises the side bar 18 of two longitudinal extensions between bearing 16 at least, auxilliary beam 20 also can be fixed on the bearing 16 in order to constitute the framework 14 of rectangle, and these auxilliary beams 20 also can replace with crossbeam 22 of the present invention.As shown in Figure 1, embody on the side bar 18 that suspension type crossbeam 22 of the present invention removably is fixed on framework 14.

Referring now to Fig. 2 and Fig. 3, crossbeam 22 comprises the beam member 24 that elongated two ends have identical termination 26.For the sake of clarity, only a termination 26 with regard to beam member 24 illustrates the present invention, and the assembling that uses the same method of the two ends of every * crossbeam 22.The cross-sectional plane of beam member 24 is ovalize substantially, and it has a upper surface 28 and a lower surface 30.In most preferred embodiment, the termination 26 of beam member 24 is hollow to hold the connecting device that bottom will talk about, and but, beam member 24 also can be with round tube shape structure to reduce production costs.And beam member 24 also can adopt the cross-sectional plane of Any shape, but oval 〈 ﹠﹠ maximum loading strength, and the air-flow resistance minimum.

Crossbeam 22 also comprises the termination 26 of beam member 24 is connected to the device 32 that side bar 18 gets on securely.This connecting device 32 is fixed on crossbeam 23 between the framework 14 formed planes and car surface 12 by luggage bracket 10 in the mode that hangs on the side bar 18, and comprises a connection piece 34.Attaching parts 34 has substantially L-shaped cross section, and it has a projection 36 in the hollow termination 26 that can inject beam member 24, and inwardly projection 36 has with the very close oval outer shape of the shape of beam member 24, to guarantee firm connection.In addition, with bolt or screw 38 attaching parts 34 is fixed on the beam member 24.This screw matches with the hole 42 of the inside projection of hole 40 of opening on the wall of beam member 24 and attaching parts 34, so that attaching parts 34 links together with beam member 24.

Still see Fig. 2 and Fig. 3, attaching parts 34 has a bottom surface that takes the shape of the letter U substantially 44, the shape of its shape and beam member 24 lower surfaces 30 is very close, and, although inwardly projection 36 is very near the lower edge 44 of attaching parts 34, a round platform shoulder 46 is arranged still between the lower edge 44 of projection 36 and attaching parts 34.Because the lower surface 30 of beam member 24 has the profile similar with shoulder 46, when the result connects with beam member 24 at attaching parts 34, the root edge of attaching parts 34 can with lower surface 30 concordant (as shown in Figure 3), this butt joint that flushes has substantially reduced the air-flow resistance that crossbeam 22 is produced on being fixed to the luggage bracket side bar 18 of prior art the time.
