This invention relates to a unibody support apparatus and method for use with structures with two oppositely positioned sides. In particular, in accordance with one embodiment, the invention relates, in a structure with two oppositely positioned sides, to a unibody support apparatus including a first preformed side support in the approximate form of a “C” and a second preformed side support in the approximate form of a “C”. A side support connector is connected with the first preformed side support and with the second preformed side support such that the side support connector is suspended between and by the first preformed side support and the second preformed side support. And at least one adjustable leg support, connected with the first preformed side support and the second preformed side support, is provided such that the height of the unibody support apparatus may be raised and lowered.
Machines are most useful if they are easy to set up and operate. By way of example only and not by limitation, large sewing machines and quilting machines in particular, are complex, heavy and, typically, hard to use machines. The state of the art is a complex assortment of separate plates, lengths of pipe, bolts and nuts that require a person specifically trained in the assembling of the particular machine to do so. A user is forced to call in “professional” help in order to get the machine assembled the first time and any time thereafter should he or she wish to move or modify it.
Further, the “modern” quilting machines, even when disassembled, contain parts that are too heavy for a single person to handle or too awkward to assemble alone. Thus, there is a need in the art for an apparatus and method that enables the user to simply and easily assemble a machine structure, and specifically a sewing/quilting machine. Therefore, it is an object of this invention to provide a unibody apparatus and method that enables a single user to assemble a support structure that is easy and simple and that does not require professional assistance.
Accordingly, the unibody support apparatus and method of the present invention, according to one embodiment, in a structure with two oppositely positioned sides, includes a first preformed side support in the approximate form of a “C” and a second preformed side support in the approximate form of a “C”. A side support connector is connected with the first preformed side support and with the second preformed side support such that the side support connector is suspended between and by the first preformed side support and the second preformed side support. And at least one adjustable leg is connected, with the first preformed side support and the second preformed side support, such that the first preformed side support and the second preformed side support may be raised and lowered.
According to another aspect of the invention, the first preformed side support and the second preformed side support are approximately identical and interchangeable side to side. In another aspect, the first preformed side support and the second preformed side support include attachment slots for receiving a connector at various controlled locations. In other aspects, the “C” form includes an elongated section for connection with at least one tubular roll; the “C” form includes a top and a bottom and the elongated section is at the bottom of the “C”; and the “C” form includes a top and a bottom and the side support connector is connected with the top of the “C”.
In another aspect, the at least one adjustable leg includes a first adjustable leg connected with the first preformed side and a second adjustable leg connected with the second preformed side. In other aspects, the first and second adjustable legs are connected with each other such that movement of one adjustable leg causes an equal movement of the other adjustable leg and in another, the adjustable leg is connected with a motor.
In another embodiment of the invention, in a sewing machine structure with two oppositely positioned sides, a unibody support apparatus includes a first preformed side support and a second preformed side support where the first preformed side support and the second preformed side support include attachment spaces for receiving a connector at various controlled locations and where the first preformed side support and the second preformed side support are in the approximate form of a “C” with an elongated section for connection with at least two tubular rolls. A side support connector is connected with the first preformed side support and with the second preformed side support at the attachment spaces such that the side support connector is suspended between and by the first preformed side support and the second preformed side support. And, a first adjustable leg is connected with the first preformed side support and a second adjustable leg is connected with the second preformed side support such that the first preformed side support and the second preformed side support may be raised and lowered.
According to another aspect, the first preformed side support and the second preformed side support are approximately identical and interchangeable side to side. In other aspects, the “C” form includes a top and a bottom and the elongated section is at the bottom of the “C”; and the “C” form includes a top and a bottom and the side support connector is connected with the top of the “C”.
In another aspect, the first and second adjustable legs are connected with each other such that movement of one adjustable leg causes an equal movement of the other adjustable leg; the first and second adjustable legs are connected with a motor; and the first and second adjustable legs include levelers.
According to another embodiment, in a sewing machine structure with two oppositely positioned sides, a unibody support method includes: providing a first preformed side support and a second preformed side support where the first preformed side support and the second preformed side support include attachment spaces for receiving a connector at various controlled locations and where the first preformed side support and the second preformed side support are constructed in the approximate form of a “C” with an elongated section and where at least two tubular rolls are connected with the elongated section, a side support connector connected with the first preformed side support and with the second preformed side support at the attachment spaces such that the side support connector is suspended between and by the first preformed side support and the second preformed side support and where the first preformed side support and the second preformed side support are approximately identical and interchangeable side to side and a first adjustable leg is connected with the first preformed side and a second adjustable leg is connected with the second preformed side such that the first preformed side support and the second preformed side support may be raised and lowered; and connecting a sewing machine with the side support connector.

Other objects, features and advantages of the present invention will become more fully apparent from the following detailed description of the preferred embodiment, the appended claims and the accompanying drawings in which:
The preferred embodiment of the present invention is illustrated by way of example in
As used herein the term “approximate “C” shape” refers to a shape for the first preformed side support 12 and the second preformed side support 14 that has a top section 16 and a bottom section 18 connected by a back section 20. A cutout section 22 creates a partial space between top 16 and bottom 18 and gives the supports their approximate “C” form or shape. Preferably, the bottom 18 is elongated or extended as compared to the top section 16 as illustrated. Obviously, supports 12 and 14 could be any desired shape, such as rectangular for example only, found useful to the user. Nonetheless, the approximate “C” shape is preferred because it requires less material for the creation of the supports 12 and 14 thereby making them lighter. Further, the cutout 22 creates an open working area from side to side in the unibody support apparatus as illustrated that is useful when creating quilts and the like on such a support.
A side support connector 24 connects first side support 12 and second side support 14. Once connected with first side support 12 and second side support 14 it is suspended between and by the side supports as illustrated. Preferably, side support connector 24 is conformed to receive a carriage 26 to which a sewing machine (not shown) may be attached as more fully described in Applicant's co-pending application for a Support and Cassette Apparatus and Method (U.S. patent application Ser. No. 11/543,453). In any event, side support connector 24 connects the side supports, preferably at the top 16, and adds rigidity to unibody support apparatus 10.

Connection of adjustable leg 28 and/or adjustable legs 30 and 32 also add rigidity to apparatus 10. In one aspect of the invention first adjustable leg 30 is connected with second adjustable leg 32 by leg connector 34 which adds further rigidity. Leg connector 34 may also contain a connection with the movement mechanism, gears for example as known in the art, of the adjustable legs such that movement of first adjustable leg 30 causes and equal movement of second adjustable leg 32. This feature eliminates the need to separately adjust both legs and ensures that both legs move equally thereby keeping the unibody apparatus 10 level.
Still referring to
Minor adjustments of the side support connector 24 and tubular rolls 38 are provided by the formation of some, but not necessarily all, of the attachment spaces 40 in the shape of elongated slots. As shown in
Referring now to
Again, in contrast to the state of the art where the height of the total structure is fixed, the ability to simply and easily adjust the height is a tremendous advance for a user. Where it used to require somehow removing the pressure on the supporting legs and unbolting a series of bolts to adjust the height, the present invention makes this simple and easy such that a user can adjust the height at will essentially instantaneously.
