Description
ACCESSORY CROSS BAR FOR A BICYCLE TRAILER
TECHNICAL FIELD
The invention relates to an accessory cross bar for a passenger carrier bicycle trailer having a frame with a coupling arrangement for coupling of the trailer to a bicycle at a front end of the bicycle trailer and a push-handle at a rear end of the bicycle trailer.
BACKGROUND
Passenger carriers, in particular child carriers that are equipped to be used both as bicycle trailers and as manually pushed infant strollers for use by a walking or jogging person are disclosed in US 5,344,171, US D633,825 S, US 2008/0143076 Al and US
2010/0244405 Al. When decoupled from a bicycle, the trailer can be converted into a push-type carrier provided with a generally horizontally arranged push-handle to allow the trailer to be pushed by a walking person in a manner corresponding to that of a conventional baby carrier or stroller.
Particular demands are put on a combined stroller-trailer as it needs to be light-weight while still having a strong and durable frame in order to withstand being pulled after a bicycle over a rough surface at speeds that may be considerably higher than the speeds that are attained with conventional baby carriages and strollers which are designed for walking and running speeds. It is further generally desirable that the bicycle trailers are foldable in order to occupy as little space as possible during storage or when being transported, e.g. in a car.
Moreover, the previously known dual-function bicycle trailers are optimized with regard to the trailer function, implying that they lack such accessory equipment which would be desirable in a stroller but which is not needed in a bicycle trailer. Such accessory equipment includes baskets, bags, carrier hooks, etc.

2 Accordingly, an object of the invention is to provide a means for improving the function of a passenger carrier bicycle trailer, and in particular to improve the function of a bicycle trailer that can be used as a stroller.
SUMMARY OF THE INVENTION
In accordance with the invention there is offered an accessory cross bar for a passenger carrier bicycle trailer, the bicycle trailer comprising a frame with a coupling arrangement at a front end of the frame for coupling of the bicycle trailer to a bicycle and a push-handle at a rear end of the frame. The accessory cross bar is adapted for horizontal mounting at the rear end of the bicycle trailer frame and has a non-circular cross-section.
When mounted on a bicycle trailer frame, the accessory cross bar constitutes an additional transverse reinforcement member, increasing stability of the trailer frame. The non-circular cross-section of the accessory cross bar enhances torsional resistance in the trailer frame, which may be particularly advantageous when the bicycle trailer is used in the trailer mode. When the bicycle trailer is used in the stroller mode, the accessory cross bar may be used for attaching accessories such as bags, baskets, and other luggage containers as well as holders and fixtures for cups, bottles, mobile phones, electronic monitoring devices, lights, bells, etc.
The accessory cross bar will generally be mounted in front of and/or below the push-handle at the rear end of the bicycle trailer. Common push-handles have a generally horizontally arranged gripping portion that may be straight or curved and that is connected by two generally vertically arranged struts or legs at each side of a bicycle trailer passenger compartment. The push-handle may be pivotably connected at the sides of the passenger compartment so that the angle and height of the gripping part may be adjusted. Furthermore, the bicycle trailer may have one handle at each side of the passenger compartment or a combination of a loop-shaped push-handle and side handles. The accessory cross bar may preferably be designed to be mounted between the struts or legs, and may be placed at an upper edge or slightly above an upper edge of the passenger compartment and at a distance from the gripping portion of the push-handle.
The accessory cross bar of the invention is designed for mounting horizontally at the rear end of a bicycle trailer and has an upper part and a lower part in a vertical direction of the wSLega1\069965\00003\8197332v3 ,

The accessory cross bar may preferably be designed to be mounted between the struts or legs, and may be placed at an upper edge or slightly above an upper edge of the passenger compartment and at a distance from the gripping portion of the push-handle.
The accessory cross bar of the invention is designed for mounting horizontally at the rear end of a bicycle trailer and has an upper part and a lower part in a vertical direction of the wSLega1\069965\00003\8197332v3 ,
3 accessory cross bar and of the bicycle trailer. At least the upper part of the accessory cross bar may have a rounded surface. Preferably, a major part of the outer surface of the accessory cross bar is rounded so that the accessory cross bar has no sharp edges or corners that may cause discomfort or even hurt a person gripping the cross bar such as a walking child or someone attaching the cross bar to the bicycle trailer frame.
A rounded profile on the accessory cross bar is also beneficial in that it conforms to the aerodynamic design of the bicycle trailer frame.
The accessory cross bar may have an asymmetric shape in a horizontal direction. As used herein, the horizontal direction of the accessory cross bar refers to a direction from the front to the rear of the cross bar as it appears when correctly mounted on a bicycle trailer frame. An asymmetric horizontal shape of the accessory cross bar may be advantageous in that it may be used to ascertain that the accessory cross bar is correctly mounted on the bicycle trailer frame and/or that any accessories are correctly mounted on the accessory cross bar. This is achieved by adapting any coupling members used for coupling of the accessory cross bar to the bicycle trailer frame or an accessory to the accessory cross bar to the shape of the accessory cross bar. Thereby, the specially designed coupling members will engage in a predetermined manner with the asymmetrically shaped accessory cross bar, preventing incorrect mounting of the accessory cross bar and/or of the accessories.
The accessory cross bar is preferably hollow and comprises an outer wall and an interior cavity. A hollow accessory cross bar having a non-circular cross-section can be made highly resistant to torsional forces while still being light-weight. Suitable materials for the accessory cross bar may be metal, preferably aluminium or titanium, light-weight composite materials or plastic that can be formed into a profiled accessory cross bar by conventional methods. The accessory cross bar may have one or more openings extending in a longitudinal direction of the accessory cross bar in the outer wall of the accessory cross bar in order to permit access from the outside to an inner cavity. A
longitudinal opening in the wall of the accessory cross bar will appear as a track extending along the cross bar. When a fixture or holder for an accessory is inserted into the inner cavity of the accessory cross bar, a portion of the fixture or holder will protrude out of the longitudinal opening. In the case of the accessory being e.g. a canvas covering for the trailer frame, it will typically be the covering itself that protrudes out of the opening.

VVSLega1\069965\00003\8197332v3
4 One or more vertical walls, such as one vertical wall or two vertical walls may be arranged in the interior cavity, dividing the interior cavity into sub-cavities. When at least two vertical walls are arranged in the inner cavity, the accessory cross bar may comprise an inner horizontal wall extending between two inner vertical walls in the interior cavity, resulting in the accessory cross bar having an inner H-shaped profile.
The inner cavity or one or more sub-cavities inside the accessory cross bar may be arranged to receive and retain a fastener element for an accessory. The fastener element may be arranged to be slid into the cavity from an end opening in the accessory cross bar with a portion of the fastener element or the accessory protruding out through an elongated opening in the wall of the accessory cross bar. Alternatively, the fastener element may be snapped into the cavity through an elongated opening in the outer wall of the accessory cross bar.
Snap-in accessories may include light fixtures, bells, holders for mobile phones, cup holders etc. which may be placed anywhere along the track formed by the elongated opening in the wall of the accessory cross bar. It is also conceivable to use snap-in fixtures for attaching a covering extending the full length of the accessory cross bar.
Slide-in accessories may include a covering for the bicycle trailer frame, wherein an end portion of such a covering may be inserted and retained in the inner cavity.
However, also different types of holders and fixtures for other accessories may be attached to the accessory cross bar by means of a slide-in arrangement. The slide-in fastening option is normally more permanent than the snap-in fastener option as affixing and removal of the accessory requires the accessory cross bar to be detached from the bicycle trailer frame in order to access a slide-in opening at the end of the accessory cross bar.
Accordingly, an accessory cross bar that is formed integral with the bicycle trailer frame by the manufacturer of the bicycle trailer may have non-removable slide-in accessories fastened to the accessory cross bar by the manufacturer. Such non-removable accessories may be a covering for a passenger compartment, and/or fixtures and holders constituting permanent equipment of the bicycle trailer.
Commonly available bicycle trailers have a passenger compartment with side walls and a textile or plastic covering sheet material forming a front wall, a roof and a rear wall and optionally also the side walls. The accessory cross bar may comprise two inner sub-VVSLega1\069965\00003\8197332v3 cavities each arranged to receive and retain an end portion of a cover sheet for covering of the bicycle trailer frame. Accordingly, a first inner sub-cavity may be arranged to receive and retain an end portion of a covering sheet arranged to form a front and roof wall and optionally also side walls of the passenger compartment and a second inner sub-
The inner cavity or one or more sub-cavities inside the accessory cross bar may be arranged to receive and retain a fastener element for an accessory. The fastener element may be arranged to be slid into the cavity from an end opening in the accessory cross bar with a portion of the fastener element or the accessory protruding out through an elongated opening in the wall of the accessory cross bar. Alternatively, the fastener element may be snapped into the cavity through an elongated opening in the outer wall of the accessory cross bar.
Snap-in accessories may include light fixtures, bells, holders for mobile phones, cup holders etc. which may be placed anywhere along the track formed by the elongated opening in the wall of the accessory cross bar. It is also conceivable to use snap-in fixtures for attaching a covering extending the full length of the accessory cross bar.
Slide-in accessories may include a covering for the bicycle trailer frame, wherein an end portion of such a covering may be inserted and retained in the inner cavity.
However, also different types of holders and fixtures for other accessories may be attached to the accessory cross bar by means of a slide-in arrangement. The slide-in fastening option is normally more permanent than the snap-in fastener option as affixing and removal of the accessory requires the accessory cross bar to be detached from the bicycle trailer frame in order to access a slide-in opening at the end of the accessory cross bar.
Accordingly, an accessory cross bar that is formed integral with the bicycle trailer frame by the manufacturer of the bicycle trailer may have non-removable slide-in accessories fastened to the accessory cross bar by the manufacturer. Such non-removable accessories may be a covering for a passenger compartment, and/or fixtures and holders constituting permanent equipment of the bicycle trailer.
Commonly available bicycle trailers have a passenger compartment with side walls and a textile or plastic covering sheet material forming a front wall, a roof and a rear wall and optionally also the side walls. The accessory cross bar may comprise two inner sub-VVSLega1\069965\00003\8197332v3 cavities each arranged to receive and retain an end portion of a cover sheet for covering of the bicycle trailer frame. Accordingly, a first inner sub-cavity may be arranged to receive and retain an end portion of a covering sheet arranged to form a front and roof wall and optionally also side walls of the passenger compartment and a second inner sub-
5 cavity may be arranged to receive and retain an end portion of a covering sheet arranged to form a rear wall of the passenger compartment.
The accessory cross bar of the invention may have accessories that are attached on the outside of the accessory cross bar as well as accessories attached by being inserted into an inner cavity in the accessory cross bar either by sliding-in through an end opening in the accessory cross bar or by a snap-in attachment through a longitudinal opening or track in the accessory cross bar.
The accessory cross bar may be an integral, pre-mounted part of the bicycle trailer frame.
An integral accessory cross bar provides the manufacturer with a means of deciding the exact positioning of the accessory cross bar on the bicycle trailer frame and to ascertain correct and secure mounting of any permanent equipment attached to the accessory cross bar. An integral accessory cross bar will also add minimal weight to the bicycle trailer frame as no fastener elements for fastening of the accessory cross bar to the bicycle trailer frame are needed. Furthermore, by making a pre-mounted accessory cross bar with a non-symmetrical cross-section, the manufacturer can ascertain that any user mounted accessories are mounted in a correct way on the accessory cross bar.
Alternatively, the accessory cross bar may be separate from the bicycle trailer frame such that it may be attached to the bicycle trailer frame by a user of the bicycle trailer. A
separate accessory cross bar may comprise attachment members for repeated attachment and removal of the accessory cross bar from the bicycle trailer frame. A
separate accessory cross bar avails a user with the option of deciding whether to mount an accessory cross bar or not on the bicycle trailer. Furthermore, a separate accessory cross bar can be removed from the bicycle trailer when not needed, for instance when there is a desire to minimize the weight of the bicycle trailer. A separate accessory cross bar may be conveniently stored by a user optionally together with any accessories affixed thereto during periods when it is not needed and can subsequently be attached to the bicycle trailer frame together with the accessories when desired.

Furthermore, it is to be understood that the shape and construction of the bicycle trailer frame 2 may be different from that shown in Fig. 1. For instance, the shape of the passenger compartment may be different, the bicycle trailer may have two front wheels, etc.
The accessory cross bar 15 is shown to be permanently mounted on the bicycle trailer frame 2 by means of end fixtures 17 such that the accessory cross bar 15 is an integral component of the bicycle trailer frame 2.
Furthermore, the bicycle trailer 1 in Fig. 1 is shown with two accessories 18,19 attached to the accessory cross bar 15 by means of clamping members 20 which grip the accessory cross bar 15 from above and hold the accessories firmly in place on the accessory cross bar 15. The first accessory 18 is a frame for a front luggage compartment that may be used to hold a computer or similar item, and the second accessory 19 is a frame for a device that may be a holder for cups, cans, keys, a wallet, a mobile phone, etc. The shown accessories 18,19 are only examples of accessories that may be attached to the accessory cross bar 15 and it should be understood that any other type of accessory may be attached to the accessory cross bar 15, as disclosed herein. Similarly, the clamping members 20 may be substituted with other types of fastening means such as screw-on fasteners, snap-on fasteners, etc. as known in the art.
Fig. 2 shows a portion of the bicycle trailer frame 2 in Fig. 1 in the area of the accessory cross bar 15. The accessory cross bar 15 is shown without any accessories mounted thereon revealing that it has a flattened shape with an upper part 21 and a lower part 22 and a rounded upper surface 23 at the upper part 21 of the accessory cross bar 15.
The bicycle trailer frame in Figs. 1 and 2 has an adjustable push-handle 8.
The push-handle is attached to the struts 11 with pivot joints 24 which allow the angle a between the WSLega1\069965\00003\8197332v3 push-handle 8 and the struts 11 to be adjusted. In Fig. 1 the push-handle 8 is shown in a generally upright position with the horizontally arranged central gripping portion 9 raised above the accessory cross bar 15. Fig. 2 shows the push-handle 8 in a position where it is almost level with the accessory cross bar 15.
Figure 3 shows a view similar to the view in Fig. 2 but with the accessories 18,19 as shown in Fig. 1 mounted on the accessory cross bar by means of the clamping members being clamped over the rounded upper surface 23 of the upper part 21 of the accessory cross bar 15.
Figs. 4 and 5 show an accessory cross bar 15 which may be used with the bicycle trailer frame 2 in Figs. 1-3. However, it is to be understood that the inner structure of the accessory cross bar 15 in Figs. 4 and 5 are optional features of the accessory cross bar in Figs. 1-3. As in Figs. 1-3, the accessory cross bar 15 in Figs. 4 and 5 is shown to 15 have a flattened shape in the vertical direction V, with an upper part 21 and a lower part 22 and a rounded upper surface 23 at the upper part 21 of the accessory cross bar 15.
The accessory cross bar 15 has a front portion 25 and a rear portion 26 which are intended to be facing to the front and to the rear, respectively, when the accessory cross bar 15 is mounted in a bicycle trailer. As is seen in Fig. 5, the front portion 25 and the rear portion 26 differ somewhat in shape so that the accessory cross bar 15 is asymmetrical in the horizontal direction H.
The accessory cross bar 15 in Figs. 4 and 5 is hollow with an internal cavity 30 divided into subcavities 30a, 30b, 30c and 30d by two inner vertical walls 31a, 31b and an inner horizontal wall 32. The inner vertical walls 31a, 31b and the inner horizontal wall 32 form a generally H-shaped inner profile inside the outer wall 33 of the accessory cross bar 15.
The inner walls 31a, 31b and 32 constitute an inner reinforcing and stabilizing structure inside the accessory cross bar 15 and also have the function of delimiting the subcavities 30a-30d which may be used to receive and retain portions of fixtures and accessories as disclosed herein.
The accessory cross bar 15 has three elongated openings 34a, 34b and 35 extending in in the outer wall 33 in the longitudinal direction L of the accessory cross bar 15. The elongated openings 34a, 34b and 35 permit access from the outside to the inner subcavities 30a and 30b in the front and rear portions 25, 26 of the accessory cross bar vvsLegal\069965\00003\8197332v3 15 and to a central subcavity 30d in the lower part 22 of the accessory cross bar 15. The longitudinal openings 34a, 34b and 35 in the outer wall 33 of the accessory cross bar 15 appear as longitudinal tracks in the lower part 22 of the accessory cross bar 15.
Fig. 6 is a view of an end 36 of the accessory cross bar 15 in Figs. 4 and 5 which for the purpose of illustration is shown attached only with the non-visible opposite end in a fixture 17 on a bicycle trailer frame 2. The accessory cross bar 15 has an accessory 37 in the form of a fixture for an electronic device such as a speedometer or similar attached thereto by means of a clamping member 20 which is clamped over the upper part 21 of the accessory cross bar 15. The clamping member 20 has a shape which is adapted to the asymmetrical shape of the accessory cross bar 15 so that the clamping member will only fit on the accessory cross bar 15 in the way shown in Fig. 6. In this manner, it is ascertained that the accessory is correctly mounted on the accessory cross bar 15.
Figs. 7 and 8 show the accessory cross bar 15 in Figs. 4-6 being used for securing a covering 40 for the passenger compartment of a bicycle trailer frame (not shown in Fig. 7).
The covering comprises a front covering sheet 40a and a rear covering sheet 40b. The covering sheets 40a, 40b each have an end portion 41a, 41b. A fold has been created at each end portion 41a, 41b of the covering sheets 40a, 40b and the folded-over parts of the covering sheets 40a, 40b have been sealed along their free end to form longitudinal channels 42a, 42b into which a rods 43a, 43b have been inserted. The rods 43a, 43b having the covering sheets 40a, 40b secured thereto are shown to be inserted and retained in the front and rear inner subcavities 30a, 30b in the accessory cross bar 15.
The rods 43a, 43b can be introduced into the subcavities 30a, 30b by sliding the rods 43a, 43b in at the open end of the accessory cross bar 15 with the front and rear covering sheets 40a, 40b extending out through the elongated openings 34a, 34b in the lower part 22 of the accessory cross bar 15. Once inserted into the subcavities 30a, 30b, the rods 43a, 43b act as stopping members prohibiting the ends of the covering sheets 40a, 40b from being pulled out of the elongated openings 30a, 30b in a direction perpendicular to the direction of extension of the elongated openings 30a, 30b. In order to act as stopping members for keeping the covering sheets 40a, 40b secured to the accessory cross bar 15, the diameter, d, of the rods 43a, 43b is greater than the width, w, of the elongated openings 34a, 34b.
VVSLega1\069965\00003\8197332v3 The accessory cross bar 15 may be of the kind that is formed integral with the bicycle trailer frame by the manufacturer of the bicycle trailer such that the covering is a permanent, non-removable part of the bicycle trailer. Alternatively, the accessory cross bar 15 is a separate part allowing a user of the bicycle trailer to attach and remove the covering as desired.
Commonly available bicycle trailers have a passenger compartment with a size and shape defined by the bicycle trailer frame. The passenger compartment usually has side walls, a front wall, a roof and a rear wall. The front wall and the roof are often formed as a continuous sloped wall, with no apparent demarcation between the roof part and the front wall part. The front covering sheet 40a may form a roof 44 and a front portion 45 and optionally also side walls 46 as seen in Fig. 9. The rear covering sheet 40b may form a rear wall 47. Fig. 8 shows the accessory cross bar 15 with part of a roof 44 formed by the front covering sheet 40a and part of a rear wall 47 formed by the rear covering sheet 40b.
The stopping members at the ends of the covering sheets 40a, 40b need not be rods inserted in an end fold as shown in the figures. Alternative ways of attaching stopping members may be used such as gluing, welding, stapling, etc. may be used.
Moreover, the stopping members may be integrally formed with the covering sheet and may, for instance, be a thickened edge portion of the covering sheet. A thickened edge portion may be accomplished by rolling or folding the covering material to create a multi-layered thickened structure along the edge of the covering sheet. The thickened portion can be stabilized by mechanical or adhesive bonding or by ultrasonic or thermal welding.
Figs. 10 and 11 show a bicycle trailer frame 2 with only rear wheels 3 and a different construction of the push-handle 8 as compared with the bicycle trailer frame 2 in Figs. 1-3.
As these differences are inessential to the present invention, elements fulfilling the same function in the Figs. 1-3 embodiment and in the Figs. 10 and 11 embodiment have been designated the same reference numbers. The frame 2 shown in Fig. 10 has two connection points 50, 51 at the front of the bicycle frame 2. The connection points 50, 51 are arranged at open ends of longitudinally extending bicycle frame elements 53, 54 and are adapted to receive connecting members arranged on a front wheel arrangement or a bicycle coupling arrangement.
