Abstract

The invention relates to a bicycle holder (1) which is attached to the tailgate (11) or roof (6 ') of cars (6) and which allows transport in four different optional ways (2). Each bicycle (7) is fixed in two rim brackets (28). 28 ') and in a frame bracket (12) and does not touch the nearest bicycle (7). The adjustable clamps (25, 26, 27, 60) of the bike carrier (1) have slightly resilient plastic-coated fingers (35) that reduce the risk of paint damage or glass damage to the car (6) and can be fitted with shock-proof safety catches (37). For example, 4 bicycles (7) S1 / S2-apterase (2 ', 3'), i.e. In order to minimize air resistance, the Sl fitting (2 ') is preferably used. The bike carrier (1) is collapsible in a compact parking position (8) and thus does not need to be removed from the car (6) after use.The tailgate (11) is always openable. The rear window wiper (71) is not obstructed. Marginal reduction of the driver's rear-view mirror. SL-fitted (2 ') bicycles (7) do not obscure the rear (brake light) of the car (6). Extra number plate may be needed depending on car type.

Description

Known technology The bike carriers on the market can be divided into three different types: a) Mounted on the car roof b) Mounted on the car's towbar cl Mounted on the car's tailgate Comments regarding these groups: HRS) b) Cl Mounted on the car roof.

Bicycles with their holders are mounted here on the same type of transverse roof brackets as usual roof boxes use.

The disadvantage of this placement of the bikes is above all the great air resistance.

Four roof-mounted bicycles can increase the car's fuel consumption by 50% - 70%.

The car's crosswind sensitivity also increases.

Short people find it difficult to place a bicycle on site. At least two people are needed the attachment.

In some transport situations, however, ceiling mounting may be preferable.

Mounted on the car's towbar.

Patents US D635,087 S and US D656,456 S are examples of bicycle holders placed on a car towbar. Holder arms to which the bicycles are attached are foldable down here, but still pose a danger damage its vulnerable position. The patent does not state the construction of the rear brackets required partly for it the foremost / innermost bicycle in the event of a hard braking shall not swing in and damage the rear of the car, and the distance protection required between the bicycles to prevent damage between the bicycles.

It can also be questioned whether the tow ball can provide a sufficiently high friction torque shock moments and if the system has a sufficiently high natural frequency (resonant oscillation).

Several different constructions based on this principle are available on the market.

Mounted on the car's tailgate The patents US 2011/0017791 A1 and USD656080 S1 are examples of bicycle holders placed on the car's tailgate. The figures show mounting on cars with a boot lid, i.e. sedan cars (34) there the car's rear window is fixed, not integrated in the trunk lid.

The bicycle holder here constitutes its simplest design of two U-shaped tubes connected in two Adjustable knot mechanisms. The U-shaped pipes support the upper side of the boot lid at two points via some soft cushions and partly the rear rear surface of said hatch. The bike carrier is pressed via said elastic cushions in place with a number of straps, two pieces fastened by means of hooks in the front edge of the tailgate, two pieces by means of hooks in the lower edge of the hatch. Two more straps are often used to better secure the attachment from slipping and swaying in the side direction of the car.

The disadvantage of this construction is partly all straps and partly the straps, which have a certain elasticity, must be tightened very tightly to avoid slipping and swaying at dynamic forces. There are no mechanically rigid attachment / support points that directly stiffen the bike carrier position. All forces are transmitted via opposing elastic straps and elastic cushions. The attachment of the bicycles is done by means of clamping devices acting in pairs against each bicycle handlebar. For three bikes, it will be 2 x 3 = 6 clamp brackets.

In addition, the missing rear holders mentioned in point (b) above.

No protection against damage according to section 9. above is also not mentioned in the patents.

The "bundling" of bicycles requires intermediate protection.

Mounting to the car of this type of bike carrier with all its belts takes in the order of 20 - 60 minutes. P.g.a. this time-consuming disassembly and assembly work is allowed in many cases the bicycle holder will remain even if the time to the next bicycle transport is long.

Most modern cars are equipped with tailgates where the rear window is integrated in the tailgate.

The tailgate, which is slightly convex and sloping, has a hinge connection to the rest of the car in the front edge of the tailgate.

The most recently described type of bicycle holder as above is also used for this type of car.

Usually either or both of the U-shaped pipes rest directly against the above-mentioned cushions rear glass surface. The glass surface is thus exposed to a fairly high point load via the cushions.

The hooks of the straps grip the tailgate in 4-6 points, i.e. two pieces in the front edge, two pieces in the rear edge and in some designs one in each side edge.

Many car models of later model years have a tailgate whose rear window forms the outermost parts of the side edges of the tailgate. The tailgate's steel frame is thus completely covered by the glass pane. To allowing the hooks of the straps to work directly against these glass edges is possible but requires good load distribution and the biasing force of the hooks should be as close to the plane of the glass surface as possible and parallel to it this to avoid breaking forces on the glass edge.

Pegeout 508 is an extreme example. The tailgate is here made entirely of glass with the respective hinges as well as the locking device attached directly to the glass.

These modern tailgate constructions place new demands on the secure attachment of bicycle holders.

The aims and features of the invention The invention, which relates to a new type of bicycle holder (1) for cars (6), essentially fulfills the above-mentioned requirements and wishes.

The characteristics of the invention are: 0 that the bicycle holder (1) can be made in variants depending partly on how bicycles (7) are desired to be fitted, partly depending on the current car type. ø that the bicycle holder (1) can be placed on the car's (6) tailgate (11) or on its roof (6 '). that the bicycle holder (1) placed on the roof (6 ') is mounted on a standard roof load holder (10) attached to car roof (6 ') or mounted in a roof box (38) attached to the roof load carrier (10). that the bicycle holder (1) allows folding to a loading position (9) and folding to a parking position (8) and thus does not need to be removed from the car (6) as it is temporarily not used. that the bicycle holder (1) does not prevent the tailgate (11, 126) from opening and does not obstruct the wiper function (71). that the bicycle holder (1) keeps the bicycles (7) physically separated from each other by the wheels of each bicycle (7) (7 ', 7 ") are fixed in two wheel mounts (28, 28', 28") and in a frame mount (12). that the bicycle holder (1) placed on the tailgate (11, 126) has clamps (25, 26, 27, 60) which are provided with a number of slightly resilient plastic-coated fingers (35) which distribute it relatively high the biasing force (36) in order to avoid paint damage and, where applicable, glass damage on the tailgate (11). Thus, the biasing force (36) can be selected relatively high. that the clamps (25, 26, 27, 60) are preloaded with a clamping mechanism (40, 40 ') which does not use elastic mechanical components (120) or long straps (74). The resulting high spring constant (49) and high prestressing force (36) provide high fixing rigidity (49 ') for the wheel mounts (28, 28 ') and the frame brackets (12) relative to the car (6). that the clamps (25, 26, 27,60) can be provided with safety catches (37) which at e.g. one frontal collision makes it impossible for them to detach from the tailgate (11, 126) as long as it is closed. that the bicycles (7) can have H-fitting (1 ') (= horizontally adapted) to the bicycle holder (1). Fig. 1, 4, 5. that the bicycles (7) can have S1 fitting (2 ') (= side fitting) to the bicycle holder (1). Fig. 2, 6, 7. that the bicycles (7) can have S2 fitting (3 ') (variant of Sl fitting for roof transport). Fig. 3, 8 - 11. that the bikes (7) can have S3 fitting (4 ') (variant of Sl fitting for sedan cars). Fig. 12. that the bicycle holder (1) in SZ fitting (3 ') is connected to the roof load carrier (10) or to the roof box (38) which on the one hand has openable housing halves (38 ') with the cavity-like wheel brackets (28 ") in which the wheels (7 ', 7 ") of the bicycles (7) are fixed and provide protected storage both in the parking position (8) and in load mode (9). Fig. 9, 10.

Fig. 15 shows a rotatably mounted wheel bracket (28 ') and axially fixed on a pin (69).

Figure explanations Fig. 1, 4, 5. The bicycle holder (1) for H-stern (1 ') has an upper load beam (15) with space for frame brackets (12).

The lower rear end portion (15 ') of the upper load beam (15) is connected via an arm (21) with a steering screw (68) to a lower load beam (14) mounted in rear clamps (25). The lower load beam (14) has horizontal, in the car (6) transversely directed pins (69) on which wheel mounts (28 ') for the wheels (7', 7 ") of the bicycles (7) are mounted. in the case of the H-adapter (1 '), each bicycle (7) is lifted sideways, slightly reclined in such a way that the wheels first enters the wheel brackets (28 ') which have a U-shaped slightly wedge-shaped cross section. Then turn the bike (7) together with the wheel brackets (28 ') to an upright position at the same time as the upper load beam (15) enters past the frame tube (70) of the bicycle (7). In this upright position, the bicycle (7) is fixed with a frame bracket (12) to the frame tube (70).

A maximum of three bicycles (7) can be transported in the version shown.

If only one bicycle (7) is to be transported, its wheels (7 ', 7 ") can be entered into the rearmost pairs of the wheel brackets (28 ') whereby the bicycle (7) can be tilted further forward towards the tailgate (11) and there fixed in a more projected position on the frame bracket (12). This gives a lower wind resistance.

If two bicycles (7) are to be transported, use the two rearmost pairs of wheel brackets accordingly (28 ').

The bicycle holder (1) is shown in Fig. 5 in the parking position (8). Here the upper load beam (15) is detached from it lower load beam (14) and pivoted about 90 degrees in its vertical bearing (72) in the housing (82). Then it has the lower load beam (14) is swung up about 110 degrees in its bearing in the clamps (25).

Fig. 2, 6, 7. The bicycle holder (1) for S1 fitting (2 ') consists of a load beam (16) mounted in the front clamping clamp (26) pins (73) (see Fig. 13). The load beam (16) rear end portions (16 ') which are horizontal and directed in the transverse direction of the car (6) has space for frame mounts (12) (not shown in Fig. 7).

The front end portion (16 ') of the load beam (16) and the front clamps (26) have wheel brackets (28) for the (7) front wheels (7 ') A lower load beam (17) is provided with wheel brackets (28) for the rear wheels (7 ") of the bicycles (7).

At the S1 adaptation (2 '), each cycle (7) is lifted sideways, slightly sideways in about 60 degrees vertical slope and directed in the direction of travel of the car (6), in such a way that the wheels (7 ', 7 ") first enter the wheel mounts (28) which have a u-shaped slightly wedge-shaped cross-section. Then turn the bicycle (7) in the wheel brackets (28) up to vertical position at the same time as one rear end portion (16 ") of the load beam (16) enters at the frame tube of the bicycle (7) (70). When the cycle (7) is lowered, it will be wedged in the three points A, B and C indicated in Fig. 6.

When each cycle (7) is connected with the frame bracket (12) in its frame tube (70) at point A (Fig.6), the cycles become completely fixed in all load directions.

For smaller bicycles (7), the end portion (16 ") is instead entered under the front fork (73) of the bicycle (7) and through its front wheels (7 ').

The number of places for bicycles (7) has theoretically no limit. In practice, a maximum of four pieces is suitable.

Due to the orientation of the bicycles (7) relative to the direction of travel of the car (6), the wind resistance is lower than for the alternative H-fitting (1 ') and the bikes (7) do not obscure the rear / brake lights.

The bicycle holder (1) is shown in Fig. 7 in the parking position (8) and in the load position (9).

Fig. 3, 8 The bicycle holder (1) for SZ fitting (3 ') is here attached to a roof load holder (10) which is attached to the roof (6 ') of the car (6). The bicycle holder (1) has the same basic structure as previously mentioned bicycle holder (1) for Sl fitting (2 ') with here a load frame (18) which is rotatably mounted in a vertical plane in bearing blocks (75) attached to the front transverse load bar (13 ') of a standard roof load carrier (10). One support rod (23) is mounted in a support element (76) attached to a load beam (19) attached to the roof load carrier (10) rear transverse load bar (13 ").

The bicycles (7) are fixed to the frame brackets (12) and the wheels (7 ', 7 ") are erade xeradei the wheel brackets (28) on the horizontal bar (18 ') of the load beam (18) and on the rear load beam (19) respectively.

The S2 adaptation (3 ') of the bicycles (7) takes place in approximately the same way as in the previously described S1 adaptation (2 ').

Fig.9, 10 The bicycle holder (1) for SZ aft (3 ') is here attached to a roof box (38) which is attached to roof rack holder (10) which is attached to the car '(6) roof (6'). Fig. 10 shows the parking position (8) where the steering wheel screw (68) secures the support beam (23) of the bicycle carrier (1) against the load beam (18).

Two cover doors (38 ') are each mounted in hinges (77) attached to the lower cover (38 ") of the roof box (38). the cover doors (38 ') in Fig. 10 are shown here half open.

The cover doors (38 ') are provided with the cavity-like wheel brackets (28 ") for the wheels (7', 7") of the bicycles (7).

The wheel mounts (28 ") are designed so that the wheels (7 ', 7") are fixed by wedge action.

The cover doors (38 ') are preferably made by vacuum forming or injection molding of plastic. FIG. 9 shows two bicycles (7) which rest in the wheel mounts (28 ") and which are also fixed by means of the frame mounts (12). on one rear portion (18 ") of the load beam (18) to its frame tubes (70) or front wheel forks (70 ').

In Fig. 9, the bicycle handlebars (78) of the bicycles (7) are rotated about 90 degrees, which facilitates the fitting of the bicycles (7). and slightly reduces wind resistance.

Lie shows a previously known method of reducing wind resistance by the bicycles' (7) front wheels (7 ') are dismantled and transported elsewhere in the car (6).

Within the scope of the invention Bicycle holder (1) for SZ fitting (3 '), the front forks (70') are rotated approx. 90 degrees and wedged in the front of the wheel brackets (28 ") at the same time as the horizontal rear portions of the load beam (18) (18 ") which is here lowered to a slightly lower position (79) in order to be able to be connected to the frame tubes (70) of the bicycles (7) by means of the frame bracket (12). The rear wheels (7 ") are xered as before in the wheel mounts (28").

Fig. 12 The bicycle holder (1) for SZ aft (4 ') is here slightly modified to fit sedan cars (6 ") tailgates (126). The rear window (51) of the car (6) is fixed, not integrated in the tailgate (126).

The clamping mechanism (40 ") is slightly modified compared to the clamping mechanism (40) for the S1 fitting (2 ').

The bicycle holder (1) is shown in the parking position (8) and in the load position (9).

Fig. 13 shows one of the front clamps (26) provided with a spring-loaded safety catch (37) which prevents the respective clamping claw (26) from sliding out of its engagement in the slot (80) of the tailgate (11) at a shock load (81).

Fig. 14 shows a front clamp (60) with metal strip (62) and screw rod (63). This is a alternative to clamping clone (26) and is primarily intended for the bicycle holder (1) in H-fitting (1 ').

Lig = _1_5 shows a wheel bracket (28 ') secured against axial movement on the pin (69) and with limited rotary movement by means of a screw (82) acting in a groove (83). The wheel bracket (28 ') is preferably made in injection molded plastic possibly with fiber reinforcement. The wheel bracket (28 ') is here adapted for the H-fitting (1').

The invention thus allows the bicycles (7) to be fitted in the following four optional ways (all of which are based on principles of the invention): o H-fitting (1 ') (tailgate mounting, horizontal) 0 S1 fitting (2 ') (tailgate fitting, side) o S2 mounting (3 ') (ceiling mounting, side) 0 S3 mounting (4 ') (tailgate mounting, side, for sedan cars (6')) All versions of the bike carriers (1) provide the same mute attachment to the car (6, 6 ') and to each bike (7) by means of the two wheel mounts (28, 28 ', 28 ") and the frame mount (12) which also ensure that no physical contact is between the bikes (7).

No long elastic straps (74) are used.

The frame brackets (12) are not inserted or symbolically inserted in the figures. Their placements are numbered instructed. The frame brackets (12) can in their simplest form consist of short straps (74) or of so-called GRAB- band (2), an invention not included in this patent application.

Fig. 1 shows a pair of wheel mounts (28) of a bicycle (7) at points B and C. These are angled. When moving horizontally, the bicycle (7) will unroll along the circular arc shown. When applying the frame bracket (12) at point A, the cycle (7) will thus assume a small acceptable horizontal inclination deviation depending on the size and construction of the bike (7).

One or more bicycle handlebars (78) may need to be loosened and turned slightly so as not to collide with other bicycles (7) All types of bicycles (7) including women's bicycles can be attached with all the fitting methods according to the invention.

The detailed design of the invention Detailed version of the bicycle holder (1) for H-fitting (1 '), S1-fitting (2'), S2-fitting (3 ') and SS-fitting (4 ') differ slightly from each other.

For the bicycle holder (1) for H-fitting (1 ') the following applies: See first the Figure Explanation for Figs. 1, 4, 5.

The load beam (15) is its front end portion (15 ') vertically mounted in a housing (82). A bearing block (83), attached to the load beam (15), forms an axial bearing (84) in that it is slidable in a groove (53) in the housing (82).

The load beam (14) is stored in the rear clamps (25). the task is to pre-tension the rear clamps (25), which grip the tailgate (11) lower edge (11 ”), towards the front clamp (60).

The housing (82) is mounted on the rod (14 ') by means of the bracket (54). vertical position (85) of the housing (82) relative the rod (14 ') can be adjusted, to fit the size of the car (6) in question, by selecting suitable screw holes (86) in the bracket (54) for screws (86 ').

The upper end portion (82 ') of the housing (82) is provided with a transversely directed hole (87) in which a bearing bushing (88) is stored. A support (89) consisting of a support body (89 ') with a support body (89') is mounted on the bearing bushing (88). load-distributing slightly elastic body (89 ") acting against the tailgate (11).

The bearing bushing (88) has a hole (90) drilled in its transverse direction in which a clamping bolt (60) screw rod (63) runs.

Fig. 14 shows the clamping details (60) included details. A claw (61), provided with a number of slightly resilient fingers (35), are rotatably attached to a metal band (62) by means of the rivet (61 '). A support (65) is attached to the metal strip (62) in one of the holes (64). The support (65), which has a slightly resilient body (66) which distributes the abutment force against the rear window (51) or the tailgate (11), is used when the metal band (62) is not allowed load any plastic spoiler (91) ("duck-tail").

In the opposite end portion (62 ") of the metal strip (62), the screw rod (63) is fastened by means of the rivet (63 ').

A knob (92) is attached to the screw rod (63).

Before mounting the bicycle holder (1) on the car (6), first make the following one-time settings for the car in question (6): partly for clamping clone (60) by selecting the designated hole (64) in the metal band (62) partly for the clamps (25) by selecting the designated hole (86) on the bracket (54). partly for the stop nut (113) through the correct position (113 ').

(Position of the stop nut (113) (113 ') indicates how much the knob (92) should be screwed counterclockwise to clamp (25) must be able to enter over the edge (11 ") and thus give instructions for later assemblies / disassembly).

Then fold out the bike carrier (1) in load position (9) and fix with the steering wheel screw (68).

The angled fingers (35) of the rear clamps (25) are then inserted into a gap (80) constituting the distance between the rear edge (11 ") of the tailgate (11) and the edge (6") of the car (6). Then turn the support (89) to the appropriate position on the tailgate (11) and clamp (60) (ngars (35) are pushed into place in the slot (80).

The tailgate (11) may need to be opened slightly when connecting the claws (25, 61) in the slot (80).

Finally, tighten the bicycle holder (1) in place by means of the threaded steering wheel (92).

For the bicycle holder (1) for Sl fitting (2 ') the following applies: See first the Figure Explanation for Figs. 2, 6, 7.

The front clamp (26) (see Fig. 13) pins (73) sit on a threaded body (93) which has a first approximately horizontal, in the direction of travel of the car (6) directed threaded first hole (94 ') in which a threaded rod (95) is screwed on. In the opposite front end (95 ') of the rod (95) is a pin (96) (only indicated in the figure) attached to which a claw (50) with resilient fingers (35) is rotatably mounted about. A spring loaded The safety catch (37), which is mounted on the pin (97) on the rod (95), has a locking tongue (37 ').

When mounting the bicycle holder (1), the angled fingers (35) of the front clamps (26) are lowered into the front column (80).

When the fingers (35) are in place, the locking tongue (37 ') of the spring-loaded safety catch (37) will automatically slide into the slot (80).

In the event of a shock load (36 ") exceeding the prestressing force (36), the fingers (35) are prevented from slipping out of the gap (80) of the locking tongue (37 ').

The length of the clamp (26) is adjustable by the threaded rod (95) moving in the threaded body (93) threaded holes (93 ').

The minimum setting step (98) corresponds to the pitch (93 ") of the threaded hole (93 ').

The front edge (11 ') or rear edge (11 ") of the tailgate (11) or both may for some cars (6) consist of rear window (51) edge (51 '). Therefore, the biasing force (36) of the claws (50, 27) must abut the edge (51 ') is distributed over relatively long edge lengths (51 ").

The claws (50, 27) are therefore made of a thin, hard and resilient material (58) and have a relatively large claw width (59) and are provided with a plurality of narrow fingers (35).

The pin (96), the threaded hole (94 ') and the thin material (58) provide an automatic alignment of the fingers (35) of the claws (50) relative to the often slightly arcuate edge (11 ', 11 ", 51') edge length (51").

To further protect the edges (11 ', 11 ", 51'), the fingers (35) can be given a thin protective plastic layer (56) and thereby minimizes the risk of paint damage (57) on the edges (11 ', 11 ") and / or edges of the tailgate (11) glass damage (57 ') on the rear window (51) edge (51') occurs.

The thin material (58) means that the clone (50, 27) fits even when the gap (80) is small.

The tailgate (11) may have to be opened slightly even at the connection in the slot (80). 10 The threaded body (93) has an approximately vertical and approximately perpendicular to the first hole (94 ') second threaded hole (94 ") into which a threaded rod (95") is threaded. The threaded rod (95 ") passes a clearance hole (102) in the tube (103) and strikes the inner surface (104) of the tube (103). The tube (103) is provided with an elastic support member (47) resting on the tailgate (11) or on its rear window (51).

A slightly elastic support body (99) is placed on the threaded body (93) and rests against the rear of the tailgate (11) upper edge (105) which in some cases consists of a spoiler (91) ("duck tail") of plastic which is usually quite weak.

By adjusting by means of the threaded rod (95 "), it can be directed towards the tailgate (11) the force component (36 '), which is formed when the biasing force (36) is applied, is given a desired force distribution (52) between the support member (47) and the elastic support body (99). The rear clamp (27) can also be provided with similar spring-loaded safety catches (37) which act in the rear edge (11 ") of the rear edge (11) of the corresponding slot (80).

Approximately in the middle of the rod (16 ') a bent sheet metal strip (106) is rotatably mounted. The sheet metal strip (106) is provided with holes (106 ') to which a clamping mechanism (40) is attached.

The clamping mechanism (40 ') is shown in Figs. 6, 7. It consists of a screw rod (41) axially mounted on a bearing pulley (107) mounted mounted in the hole (106 ') of the sheet metal strip (106). The knob (108) is attached to the screw rod (41). The screwdriver (41) is enclosed in its lower end portion (41 ") in a horizontal bearing pin (122) directed in the transverse direction of the car (6) stored in a support bar (109). A support rod (22) is mounted in the upper end portion (109 ') of the support rod (109) by means of a bearing pin (110). Two parallel levers (45) are also mounted on the bearing pin (122) and attached at their opposite ends to a cylindrical, horizontally transversely directed rod (46) on which a number of the elastic support elements (47) are stored. The support elements (47) rest on the tailgate (11) of the car (6).

In the lower end portion (109 ") of the support rod (109), clamping clamp (27) is adjustably fastened in step (44) by means of screws (111) and nuts (112) in designated holes (43).

The levers (45) transmit the force component (36 ') directed towards the tailgate (11), which is then formed. the biasing force (36) is applied by means of the knob (108) to the support elements (47) and also ensures that a clearance (48) is maintained relative to the rear window wiper (71) of the car (6) during application.

A horizontal transverse support beam (17) is fixedly attached to the lower end portion of the support rod (109) (109 '). On the support beam (17), two support elements (47) are placed which support against the tailgate (11).

Four wheel brackets (28) are also fixed to the support beam (17).

The bicycle holder (1) is mounted on the car (6) as follows: First, the following one-time settings are made for the current car (6): partly for the clamping claws (26) by turning the claws (50) to the specified axial dimension. partly for clamping claw (27) by selecting the indicated hole (43) on the support rod (109). partly for the stop nut (113) through the specified end position (113 ').

(Position of the stop nut (113) (113 ') indicates how much the knob (108) must be screwed counterclockwise to clamp (27) must be able to enter over the edge (11 ") and thereby facilitate later assemblies / disassemblies). Fold out the load bar (16) and the support bar (22) and fi xerate them with the steering wheel screw (68). 2. Connect the front clamps (26) to the front edge (11 ') of the tailgate (11). Possibly must the tailgate (11) then opens slightly. 11 3. Open the tailgate (11) slightly and hook the clamp (27) on the edge (11 ").

Then turn the knob (108) clockwise. In this case, the levers (45) will be turned counterclockwise the rod (46) until the correct biasing force (36) is reached in the screw rod (41). See below mounting that the elastic elements (47) support in a suitable place on the tailgate (11). 5. Close the tailgate (11).

For the Bicycle Holder (1) for SZ fitting (3 ') the following applies: See first the Figure Explanation for Figs. 3, 8 - 11.

The bicycle holder (1) for S2 fitting (3 ') largely corresponds to Bicycle holder (1) for S1 fitting (2') except that the clamps (26, 27) and the clamping mechanism (40 ') are removed.

It must instead be connected to a standard roof load carrier (10) mounted on the car's (6) roof (6 ').

The SZ adaptation (3 ") of the bikes (7) is similar to the S1 adaptation (3 ').

See Figs. 3, 8 and its explanations of figures.

The bicycles (7) are here approximately parallel horizontally established in the direction of travel of the car (6).

To distribute the resulting acceleration forces (100), mainly in the direction of travel of the car (6), approximately equal to the front clamps (10 ') and the rear clamps (10 ") connect a drawbar (101) the support element (72) and the rod (18 ') (alternatively the load beam (13')).

The bicycle holder (1) for S2 fitting (3 ') can be folded into a parking position (8) by the steering wheel screw (68) unscrew and the load beam (18) folds backwards to an approximately horizontal position. Then fold down the support bar (23) forward and fixert against the load beam (18) with the steering wheel screw (68).

The bicycle holder (1) can alternatively be placed in a roof box, as shown in Figs. 10, 11, 12 and their explanations of figures.

For the bicycle holder (1) for S3 fitting (4 ') the following applies: See first the Figure Explanation for Fig. 12 A steering wheel (108 ') attached to a screw rod (41') mounted in a fork (121) mounted in a spindle (122 ') mounted in the upper end portion (123 ') of the rod (123), in conjunction with a nut (124), hinged to a sheet metal belt (125) mounted on the front part (20 ') of the load beam (20), provides a rough setting for the current sedan car (6 ') tailgate length (126).

The wheel mounts (28) for the front wheels (7 ') of the bicycles (7) are foldable in pairs to provide greater compactness. parking mode (9).

The rear clone (27) with the wheel mounts (28) corresponds to the design of the S1 fitting (2 ') and has the same setting options in discrete steps (44).

The locking mechanism (40 ") biases the bicycle holder (1) with a steering wheel screw (68), threaded into a transverse thread (122 ") (not visible in Fig. 12) in the spindle (122 '), actuating a support member (123) consisting of a plate (123 ') with some elastic pad (123 ") supporting the tailgate (126).

The claws (25 ') are here directly articulated attached to the clamping claws (25) which form bearings for the load beam (20). 12 Calculation of the biasing force (36) 1. Assume the value of the steering wheel M (92, 108) torque M is 2.5 Nm.

Set the pitch of the threaded screw rod (41) p = 1.25 mm. (M8 thread) Assume that the screw rod (41) has the efficiency n = 35%.

Assume the bearing friction coefficient of the screw rod (41) fi cient u = 0.1.

Set the bearing friction radius R = 6 mm = 0.006 m of the screw rod (41) The biasing force (36) calculation formula is -) F = (M - F x u x R) x 2000 x 3.14 x n / p .ml fl PWN The above inserted values give the biasing force (36) F = 2139 N in the screw rod (41).

The maximum total weight _rr_i of the bicycles (7) is about 60 kg. a = F / m = 2139/60 = about 36 m / sl. Such a high acceleration can never occur, which gives a great safety margin to allow the bike carrier (1) to lift from the tailgate (11, 126).

Assume that the dimension of the screw rod (63, 41) is MQ with a core radius r = 3.3 mm.

This gives a screw stress o = F / (n x ri) = 63 N / mm ' This means a safety margin of about 6 -8 times, which is reassuring even for high shock loads.

Alternative embodiments within the scope of the invention The described clamping mechanisms (40, 40 ', 40 ") can all be used in some modified forms for all adaptation modes H-fitting (1 '), S1-fitting (2') and S3-fitting (4 '). ø The wheel bracket (28) can be fitted with, analogously to the wheel bracket (28 '), a bearing directed in its longitudinal direction (130) with a limited tilt (131) to facilitate the S1 fitting (2 '), the S2 fitting (3') and the S3 fitting (4 ') The metal band (62) in the clamping mechanism (40) can be exchanged for a wire bias (127). ø The screw rod (41) can be replaced with a wire bias (127 '). o The screw rod (41 ') can be replaced with a wire bias (127 "). o A limitation of the biasing force (36) can be obtained by introducing a torque limitation function.
