Abstract
The invention concerns a rain screen which is attachable toa bicycle, moped, e bike or scooter, comprising a shaft with ribs for supporting a web; the web comprising a discontinuity between a first rib and a second rib for providing a head opening with a covering section at a distance above the web partially in register with the head opening wherein the covering section is supported by an extended top of the shaft and by either extended tensioners of the first and second rib or by the distal ends of the first en second rib.
Description
FIELD OF THE INVENTION
The present invention relates to the field of a rain screen which is attachable to a bike.
BACKGROUND
An umbrella (rain screen) mounted on the steering wheel of a bicycle is presented in Dutch patent 1014056. This umbrella serves to keep the driver dry when cycling in the rain. Because of the umbrella, the driver does not need to wear rainproof clothing to stay dry. Patent 1014056 shows an umbrella which is mounted on the steering handle bar of a bicycle such that the position of the screen is adjustable to protect the driver from the rain for different driving speeds and wind directions. The umbrella is positioned above the head of the driver to allow the driver a free view of the surroundings and the road. Due to the relatively high position of the screen, the overturning moment due to side winds is relatively high, creating a risk of toppling of the bicycle. And due to the relatively high position of the screen, there is relatively little protection against the rain when driving or with wind.
SUMMARY
It is preferred to reduce at least some of effects of the disadvantages indicated above. Among others, it is preferred to improve the protection against rain by providing a (rain)screen that may be carried lower relative to the body.
An aspect of the present invention provides a rain screen, comprising a frame, wherein the frame is attachable to a bike, a canopy attached to the frame comprising a web and a plurality of ribs for supporting the web, which ribs are at proximal ends connected to the frame, the web comprising a discontinuity between a first rib and a second rib for providing a head opening, wherein the rain screen further comprises a covering section at least partly provided at a distance from the web at least partially in register with the head opening.
A canopy is a cover, comprising a web preferably comprising a woven or non-woven fabric as a covering material, spanned or spannable over the plurality of ribs. The web comprising a discontinuity is defined as a web comprising one or more holes and/or one or more sections that are omitted such that the web does not cover the entire area spanned between the ribs over which the web is spanned.
The discontinuity of the web provides a head opening, which is arranged such that a user may provide his head through the head opening. The head or neck may be provided in or through the discontinuity of the web. Alternatively or additionally, the head opening may provide a viewing window for a user who is at least partially covered by the canopy.
The frame may be attachable to a bike, moped, e-bike, scooter or any other vehicle without a roof to protect a user of the vehicle from rain whilst driving the vehicle. A user riding the bike and using the rain screen according to the present invention will thus be at least partially protected from rain by the rain screen.
The ribs may extend substantially radially from the frame, and the web may be spanned over the ribs. The spanned web may provide a force pulling the first rib away from the second rib. If the discontinuity were to be present over the entire area between the first rib and the second rib, this pulling force cannot be transferred between the first rib and the second rib causing an unstable shape of the web. Therefore, a tensioning element such as a small strip of web material is arranged to limit a maximum substantially tangential distance between the first rib and the second rib, or, stated differently, to limit the distance between distal ends of the first rib and the second rib.
In an embodiment of the rain screen, the frame comprises a shaft having distal ends of the ribs hingedly connected thereto at a rib connection position, a runner arranged to be translated relative to the length of the shaft between a first position and a second position, and stretchers, at a proximal end hingedly connected to the runner and at or near a distal end connected to the ribs, wherein when the runner is translated from the first position to the second position, the web is spanned by the stretchers pushing distal ends of the ribs away from the shaft, and when the runner is translated from the second position to the first position, distal ends of the ribs are pushed towards the shaft by the stretchers;
In an embodiment of the rain screen, the first position of the runner is a bottom position when the rain screen is not in use, and the second position of the runner is a top position when the rain screen is in use.
When the rain screen is in use, the covering section at least partially prevents rain falling on top of the rain screen from falling through the head opening - or on a head sticking through the head opening. Instead, rain falls onto the covering section and may flow of the cover section for example onto the web.
In an embodiment, the covering section is connected to the extended shaft by means of a connection at a distance from the rib connection position.
The frame may further comprise two extended stretchers, at a proximal end connected to the runner and at or near a distal end connected to the covering section, such that the two extended stretchers are arranged for tensioning the covering section from the frame.
In another embodiment of the rain screen, the covering section is supported by two extra ribs with their proximal ends connected to the extended shaft.
In another embodiment of the rain screen, the covering section is spanned by a third rib with its proximal ends connected to the shaft top.
Two side flaps may be connected to and provided between the web and the covering section. The side flaps may shelter a head provided in the head opening from rain coming from the sides of the head opening.
In the description below, the following definitions are used interchangeably: opening in the screen and head opening; tube, tube extension, and shaft; web and non-continuous screen; upper screen and covering section; extended top and extension section; sliding connection and runner; web and non-continuous lower section; tensioners and stretchers.

DETAILED DESCRIPTION OF THE EMBODIMENTS
Figure 1 shows schematically a side view of the device according to the invention whereby on behalf of clarity of the figure certain components have been left out and where a covering section (10) is shown below which the head of the driver can be positioned.
Figure 2 shows schematically a front view of the device with the same components as presented in figure 1. The discontinuous web (1) comprises an opening (2) between two ribs through which the head of the driver may be positioned. The ribs (3) of the screen provide for support of the foldable flexible material of the web (1). The shaft (4) of the screen is connected via component (5) to the shaft extension (6). The shaft extension is connected to the bicycle via component (7). In the preferred form of the device, the connection (5) is provided with means to connect the shaft detachable to the bicycle so that the screen can be easily attached to and detached from the bicycle.
The foldable flexible material of the covering section (10) is tensioned between two extended stretchers (9) and a the extended top (13). The covering section includes two side flaps (12) for improved protection against the rain, leaving a free view on the road for the driver.
Figure 3 presents a top view of the screen with a selection of the components which have been presented in figures 4 and 5.
Figure 4 shows schematically how the frame, web en covering section are folded with the sliding hinged connection (14) of the ribs (8) of the covering section (10) to the extended top (13). In Figure 4, from left to right, the runner is translated over the shaft from the second position to the first position.
Figure 5 shows an alternative for the hinged sliding connection (14) comprising of an extended top (21) sliding adjacent to the shaft (4) with its distal end hinged connected (20) to the ribs of the covering section (8) and its proximal end connected to the runner.
Figure 6 shows schematically an alternative whereby the covering section (10) is tensioned between the extended stretchers (9) and the extended top (13). When the screens are folded, the covering section slackens.
Figure 7 shows schematically a side view of the device according to the invention whereby on behalf of clarity of the figure certain components have been left out and where a covering section (10) is shown below which the head of the driver can be positioned. The covering section is connected to the extended top of the shaft (13) and to the first and second rib (3).
Figure 8 shows schematically a front view of the device with the same components as presented in figure 7.
Figure 9 presents a top view of the screen with a selection of the components which have been presented in figures 7 and 8.
Figure 9a shows schematically how frame, web and covering section (10) are folded with the sliding hinged connection (14) of the extra ribs (8) of the covering section to the extended top (13).
Figure 10 shows schematically a side view of the device according to the invention whereby on behalf of clarity of the figure certain components have been left out and where the device is connected to a ladies bicycle instead of a man’s bicycle as has been the case in the figures 1-9.
Figure 11 shows schematically a side view of the device according to the invention whereby on behalf of clarity of the figure certain components have been left out and where the device is connected to a scooter including not only protection against the rain for the driver, but also for the passenger.
Figure 12 and 13 show schematically the adjustability by means of the preferred form of the connection (7) of the shaft extension and screen in height and angle for drivers of different sizes and so that the driver is protected from the rain at different driving speeds.
Figure 14 shows schematically a preferred form of connection (7) connecting the shaft extension (6) to the frame of the bicycle. The shaft extension (6) can be moved by the driver as indicated by the arrows of figure 14 until it is in the correct position. The shaft extension (6) can shift inside the shaft guide (17) and the shaft guide (17) has a rotation-free connection with (7).
Figure 15 shows schematically the details of the preferred form of the connection (7) with the shaft guide (15). When free horizontal and vertical movement is desired, the fixing block (18) is raised along the shaft extension (6) to above the shaft guide (15). When the shaft and the screen are in the desired position, the driver moves the shaft to make the female (16) and male (19) connection and after that lowers the fixing block (18) to fix the position of the screen.
Figure 16 shows schematically a preferred form to stow the folded screen when not used to the frame of the bicycle using connection (5) in a hinged form.
While the ribs in the figures are in the figures shown as extending at substantially the same angle from the frame, embodiments of the rain screen are also envisioned wherein different ribs extend at different angles from the frame. This may allow a non-symmetrical web to be provided, which may increase aerodynamic properties of the rain screen. Furthermore, different ribs may have different lengths.
