Description
- 1. Field of Invention
- This invention relates to a unique horizontally foldable steering wheel table, which is easy to carry and handle, will not open apart easily without an extra force in a folded-up position, and can be easily and rigidly mounted in different ways on a steering wheel of a motor vehicle, for use by a person sitting behind the steering wheel for reading, writing, eating, using lap-top computer, and cosmetics, when the vehicle is in parking position.
- 2. Description of Prior Art
- A number of devices have been created to provide a steering wheel table, some of those are foldable, but none of them will provide such a foldable steering wheel table that will not easily fall apart when in folded-up position.
- Also, those previous inventions have problems to easily and rigidly mount a steering wheel table on a steering wheel of a motor vehicle. None of these inventions are efficient enough to solve all the problems.
- U.S. Pat. No. 5,749,306 to Breuner (1998) discloses a portable steering wheel mounted computer table.
- a) This device is mounted on a steering wheel by a shock cord. This structure is not practical and rigid. The table will not be in balance, especially when there is an air bag bump on the steering wheel.
- b) It does not posses a neat and uniform appearance and looks unstable by using a shock cord or similar material when placing an expensive and heavy laptop computer on it.
- c) This device has nothing to prevent or stop a force from under the table surface, which may knock the table off the steering wheel and damage the expensive computer.
- U.S. Pat. No. 5,749,305 to Jacovelli (1998) discloses a tray for use in automobiles for placing food, drink or others.
- d) By design, this device looks not stable enough on a steering wheel and the two end of the tray may go up and down like a seesaw.
- U.K. Pat. No. GB1,550,890 to Hardy (1979) discloses a foldable steering wheel table with two hooks hanging on a steering wheel.
- e) By design, this device has nothing to prevent or stop a force from under the table surface, which may knock the table off the steering wheel, and it will not be useful when there is an air bag bump on the steering wheel.
- f) Though this device can be folded up when not in use, the table surface board will be unfolded by itself without a lock, which is not convenient for carrying.
- U.S. Pat. No. 5,558,026 to Seibert (1996) discloses a tray for use on a steering wheel.
- g) This device, which has a pocket on the top of the tray to hang on a steering wheel but has nothing else to stable the device on a steering wheel, is very easy to fall off and not stable.
- h) All of the above described inventions has no device to place or store pans, spoons, forks, other utensils, etc. on a table surface.
- Several objects and advantages of my invention include those that:
- a) will not open by itself when in folded-up position;
- b) require an extra force to separate and unfold the support and table surface;
- c) is easy for carrying;
- d) there is an oblong slot on the table surface for placing pen, utensils, etc.;
- e) by using latch or catch on the support, will greatly increase the easiness and stability of the foldable steering wheel table on a steering wheel;
- f) uses different ways of latch or catch to mount a steering wheel table for different steering wheels;
- g) by using a catch or latch, will reduce the overall size of a steering wheel table;
- h) by using one or more moveable catches or latches that can move along the support, will fit and mount on different point and place on a steering.

- Description—FIG. 1 to13
- FIG. 1 illustrates a detailed embodiment of the present invention.
- FIG. 1A and FIG. 5 show all parts of the present invention. Except springs and screws, this device can be constructed with plastic material, such as ABS, polystyrene, and polypropylene. The thickness of all walls of every part does not exceed 3 mm for big parts, and 1 to 1.5 mm for small parts. The thickness of the reinforcing ribs for the table will not exceed 1.5 mm. The table1 comprises of a
surface board ribs 25. - FIG. 2 through FIG. 6 shows the views when the support and table surface are in a position of 90 degree.
- FIG. 2 shows a table1 wider than a steering wheel and a
cup slot 2 position on the table 1. - FIG. 3 shows a front view of an
arch shape support 3 with a clamp on it. - FIG. 4 shows that the radian of the inner sidewall27 of the support is similar with the radian of the outside edge of most steering wheels. This device will fit for mounting on different motor vehicles. The
back half clamp 4 is connected with thesupport 3 byclamp axle 6. The top and bottom edges of theback half clamp 4 is designed to have a similar radian of the outside edge of a steering wheel, and the inner side of the back half clamp is also designed to have a similar radian of the ring of a steering wheel. With the force of theclamp spring 5, the device is rigidly mounted on a steering wheel. The device will not shift or move in any directions.Number 16 is a steering wheel in thesupport 3. - FIG. 5 shows a table in bottom side view.
Number 25 is the reinforcing ribs with same thickness to strengthen the table surface. - FIG. 5A shows a
cup slot 2 in a sectional view. The depth of the slot is the same as the reinforcerib 25. - FIG. 6 shows that the table1 may be constructed in a single part with the
table angle control 9 in casting, in order that thetable angle control 9 will move and push the table 1 up and down.Number 17 is a steering wheel in sectional view in thesupport 3. - FIG. 7A to7D show that the angle-adjusting
wheel 11 and angle-controlpolygonal flange plate 12 are connected to each other and are constructed as one part in casting. The plate is an irregular polygon, could be (4 sided) irregular quadrilateral or (5 sided) irregular pentagon, depending on how many adjusting levels are desired. One more side will add one more different level. - FIG. 7E is an angle-adjusting
wheel 11 in a sectional view, and FIG. 7F is an angle-adjustingwheel 11 in back view. FIG. 7E and 7F show that thepolygonal plate 12 has a square hole 29 in the middle in 2 mm deep, then changes into a round hole 29 all the way through. In corresponding to this specially designed hole, the angle-adjustingwheel axle 10 has the same characters and itsbottom end 19 is square too. As forced down by the angle-adjustingwheel spring 13, the angle-adjusting wheel axle'ssquare end 19 goes into the polygonal plate square hole 30. Thus, the angle-adjustingwheel 11 is locked and will not turn or rotate. The position of the angle-controlpolygonal flange plate 12 determines the position of thetable angle control 9 and the angle of the table 1. Because the radius of the each side of thepolygonal plate 12 to the middle point of the angle-adjustingwheel 11 is different. - FIG. 7G is an angle
adjusting wheel axle 10 in a sectional view, showing that the axle is a cylinder with a square end. - FIG. 8 shows the foldable steering wheel table with a clamp in the folded-up position in perspective view assembled of the various parts of a typical embodiment. Because of the resistance from the
limit stopper 32, the angle between the table 1 andsupport 3 will not change unless with an extra force to separate the table and support. - FIG. 8E shows the folded-up position at the point of8E-8E. FIG. 8G shows that the
limit stopper 32 is over the reinforcingrib 34 for table angle control into FIG. 8G open-up position after the springing strip bends and passes the position of FIG. 8F. If the table is being folded up with an extra force, thelimit stopper 32 will go over the reinforcingrib 34 for table angle control again to the position of FIG. 8E. This ensures that the steering wheel table will not folded-up or open by itself without any extra force. - FIG. 9 shows an alternative way (instead of clamp) to stabilize the
support 3 on a steering wheel. A springing snap latch or catch 38 is used and molded in manufacturing on thesupport 3. This springing snap latch or catch 38 can be made of plastic or stainless steel. - FIG. 9A shows the
support 3 with the springing snap latch or catch 38 in a sectional view. The lower part of the latch or catch 38 is curved inwards, thus requires an extra force to push thesupport 3 and springing snap latch or catch 38 on to a steering wheel. The steering wheel table will not fall away without an extra force to pull it out. - FIG. 10 shows another design of a latch or catch to stabilize the
support 3 on a steering wheel. A snap latch or catch 39, that is molded in manufacturing on thesupport 3, and alock 40 are used. FIG 10A shows thesupport 3 with the snap latch or catch 39 in the closed position. FIG 10B shows thesupports 3 with the snap latch or catch 39 and lock 40 in the open position. A certain force is required to close or open the latch or catch 39 in order to mount or dismount the steering wheel table on or from a steering wheel. - FIG. 11 shows another design of a latch or catch to stabilize the
support 3 on a steering wheel. A single-hinge snap latch or catch 42, that us pivotally linked by anaxle 49 on thesupport 3, and alock 41 are used.

clamp 4 and thesupport 3. - FIG. 7 shows a serial of positions of the angle-adjusting wheel and the different angles between the table1 and the
support 3. - If you need to change the table surface angle or level, simply pull up the angle-adjusting
wheel 11 for about 3 mm and turn to a desired position. When the angle-adjustingwheel 11 is released, the wheel will go back down as forced by theangle control spring 13, and there will be a snap sound whenflange point 20 on thetable angle control 9 goes into arespective recess hole 21 in angle-adjustingwheel 11. - In the illustration of this invention, a 4-sided irregular quadrilateral is used for the angle-control
polygonal flange plate 12. Every 90-degree is a position point for thetable angle control 9. By turning the angle-adjustingwheel 11 to a different position, the radius of each side of thepolygonal plate 12 to the middle point of the angle-adjustingwheel 11 is changed, which in turn changes the angle (position) of thetable angle control 9 and eventually changes the angle between the table 1 and thesupport 3. - There is one angle-adjusting
wheel 11 on each side of thesupport 3. It is necessary to adjust both wheels at the same time to the same position point. The position point on the wheel is indicated bynumbers - FIG. 8 through FIG. 13 illustrate the operation of folding-up and opening-up the foldable steering wheel table with different latches or catches.
- Summary, Ramification, and Scope
- Thus, the reader will see that the table of this invention can be folded up for easy carrying and storage, will not fall apart from the fold-up position without any extra force, and can be easily and rigidly mounted on a steering wheel,and can be removed just as easily as mounted.
- Although the description above contains many specifications, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. For example, the latch can be catch, more than one latch or catch can be used on the support of this invention. Therefore, the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given here either in writing or drawings.
