TABLE ASSEMBLY
The invention comprises a table, comprising: a) a base, the base being suitable for mounting in a vehicle, the base having a collar with one or more base pins along the interior of the collar; b) a pole, the pole being detachably coupled to the base, the pole having with one or more hockey-stick shaped slots at one end corresponding to and capable of receiving the base pins, a first lock/release mechanism for securing the pole to the base, and one or more apertures at an end opposite to the one end; and c) a table top, the table top being detachably coupled to the pillar, the top having a second lock/release mechanism for securing the top to the pillar, the second lock/release mechanism containing one or more elements which engage the one or more apertures on the pole, wherein the base, the pole and the table top combine to form the table.
The present invention relates to the field of tables. In particular, it relates to a removable table for use in cars, vans and similar vehicles.
BACKGROUND OF THE INVENTIONIn many settings, particular for passengers in vehicles, it is desirable to have a table surface available for work, recreation and/or storage. However, given the space limitations found in many vehicles, particularly minivans and passenger vans, it is not particularly desirable for the table to be permanently mounted in the vehicle. As a result, there has been an effort to design a removable table for use in these settings.
One such design is based on U.S. Pat. No. 5,383,644 to Huse for a removable pedestal. This patent discloses a pedestal mounting assembly with a removable post. The post includes a key, which fits into a key slot in the base to allow the post to be attached to the base and rotated into a mated position. Additionally, the mating between the post and the base is be accomplished by a set of oppositely spaced teeth on each. The post is designed to support a removable seat, such as on a boat and, as such, the teeth extend over a substantial portion of the post, and multiple rotations of the post are required to secure it to the base.
Another design is found in U.S. Pat. No. 4,117,784 to Piretti for a disassemblable table. This patent discloses a table which can be readily assembled and disassembled. The table consists of a top, pole and base, with the base consisting of several foot members. The foot members lock to a central hub in the base via a tongue-and-groove mechanism, and the pole and top are secured via a threaded rod. The foot member design of the Piretti table makes it unsuitable for use in a vehicle as the base is insufficiently stable to maintain the top level during motion.
A similar design is found in U.S. Pat. No. 4,178,858 to Ponzellini for a disassemblable table. This patent also discloses a table which can be readily assembled and disassembled. The table consists of a top consisting of several arm members, a pole and a base, with the base consisting of several foot members. The arm and foot members have cylindrical elements that are trapped with the tubular pole and secured by an expandable locking mechanism with the pole. As in Piretti, this design is more suited to use in a conventional table setting and not for use in a vehicle.
Yet another design is found in U.S. Pat. No. 5,560,303 to Severin for a dismantleable standing table. This patent discloses a standing table with a top, a support and a base. The various components are joined together by threaded rings, including a centering ring to align the parts. The threaded rings form part of the individual components, allowing the entire table to be (dis)assembled by hand, without needing tools.
There is a need to provide a removable table assembly which can be installed and removed rapidly, with a minimum amount of user effort. Ideally, the table assembly should not require any tools for installation. The base of the table assembly preferably takes up little vertical space, permitting use of the table assembly where space availability is limited, such as in passenger vehicles like minivans. Finally, the table assembly should be stable enough that the top surface remains level under stress and during motion of the vehicle.
It is an object of this invention to partially or completely fulfill one or more of the above-mentioned needs.
SUMMARY OF THE INVENTIONThe invention comprises a table, comprising: a) a base, the base being suitable for mounting in a vehicle, the base having a collar with one or more base pins along the interior of the collar; b) a pole, the pole being detachably coupled to the base, the pole having with one or more hockey-stick shaped slots at one end corresponding to and capable of receiving the base pins, a first lock/release mechanism for securing the pole to the base, and one or more apertures at an end opposite to the one end; and c) a table top, the table top being detachably coupled to the pillar, the top having a second lock/release mechanism for securing the top to the pillar, the second lock/release mechanism containing one or more elements which engage the one or more apertures on the pole, wherein the base, the pole and the table top combine to form the table.
Preferably, the lock/release mechanism on the table top is a handle biased by a spring mechanism, the handle extending from a lower surface of the table top.
The table can further include one or more straps located underneath the table top, the straps allowing the pole to be secured to the table top when the pole is disengaged from the base and the table top.
The invention further includes a method of assembling the inventive table.
Other and further advantages and features of the invention will be apparent to those skilled in the art from the following detailed description thereof, taken in conjunction with the accompanying drawings.
The invention will now be described in more detail, by way of example only, with reference to the accompanying drawings, in which like numbers refer to like elements, wherein:
The invention presented herein in a preferred embodiment comprises a table 10 as shown in
The elements comprising table 10 are shown more clearly in the exploded view of
As shown in
The pole 200 preferably has an aperture at its top end to allow for passage of the handle 130 from the table top 100. Also, preferably, there is a slot 205 (best seen in
The base 300, as shown in
To attach the pole 200 to the base 300, the sleeve 210 is inserted into the collar 350, aligning the pins 330 to the slots 260. After insertion, the pole 200 is rotated along the direction of the slots 260 until the locking pin 240 engages the aperture 360. At this point, preferably the pins 330 have traversed substantially the full length of the slots 260. The “hockey stick” shape of the slots 260 provides an additional frictive element to resist counter-rotation of the pole 200.
The table 10 provides the stability and support traditionally associated with a screw-threaded design, however, the combination of slots 260 and pins 330 produces that result with a minimal amount of rotation required. As shown in the preferred embodiment herein, the maximum rotation required to secure the pole 200 to the base 300 is 120 degrees, as opposed to a screw-thread design, which requires multiple 360-degree rotations.
Additionally, the table 10 requires less of the pole 200 to be secured within the base 300 than known designs. A theoretical screw-threaded pole would require several inches of thread to provide a reasonable amount of stability. The space requirements for such a design would preclude its use in a vehicle such as a minivan. By contrast, the table 10 presented herein requires substantially less space to engage the pole 200 to the base 300 and is well-suited for use in vehicles.
While the above invention has been presented in the context of mounting to passenger vehicles the invention is equally applicable to detachable tables for use in any configuration or situation.
This concludes the description of a presently preferred embodiment of the invention. The foregoing description has been presented for the purpose of illustration and is not intended to be exhaustive or to limit the invention to the precise form disclosed. It is intended the scope of the invention be limited not by this description but by the claims that follow.
