The present invention is directed to a modular dolly kit that is composed of at least two modules. The modular dolly kit can be used to transport loads that can range in weight and size.
Wheeled trucks and/or dollies, have been well documented in the art of wheeled trucks. They are usually built of robust materials that are heavy and that are not easy to maneuver or manipulate. For a detailed description of the prior art of dollies, see Chieh et al., U.S. Pat. No. 6,964,423 discloses a collapsible cross arm dolly that has four casters. The invention, although similar to the present invention, does not disclose the features and functions of the present invention. Chieh et al., discloses a collapsible cross-arm dolly that consists of an upper arm and a lower arm of square metallic tubing, with each arm formed with a horizontal offset center portion and with a pair of casters that are attached at each end of both arm's lower surface. The horizontal offset center portion is formed in opposite hand or mirror image of each other, thus permitting them to nest together and are both oppositely flattened to allow nesting on the same horizontal plane. A pivot junction is mutually disposed between the arms, thereby permitting the dolly to form a pivotal right angle cross position, or alternatively, a pivotal parallel arm collapsed position. A gravity-actuated restraint locks and disengages the connection of the upper arm to the lower arm, which permits changing orientation from the right angle cross position to the parallel arm collapsed position. A second embodiment is basically identical except a manual push-button restraint is utilized instead of being operated by a gravity actuated restraint.
The present invention does not use mirror image arms; it uses unique struts that are removably connected by a connector assembly. The present invention is similar to an erector set. The user dictates how many struts will be connected and the shape of the modular dolly. The modular dolly can be shaped to carry objects or loads that have oblong or irregular dimensions.
The present invention can be manipulated to increase or decrease areas that carry loads. The present invention does this by either adding modules (unique struts) to the structure or by adjusting the shape of the collapsible structure by manipulating the spacial relationship of each unique strut in relation to each other. The manipulation of the modular dolly is actuated by the pulling or pushing of the struts into a desired position and then locking the struts. An embodiment of the present invention may also use handles that are placed on the ends of the collapsible dolly. The handles allow any load being carried to be securely contained within the perimeter of the collapsible dolly.
In addition to Chieh et al., the following U.S. Patents are deemed relevant to the present invention: U.S. Pat. Nos. 6,382,643 Baker, May 7, 2002; 4,647,056, Baker, Mar. 3, 1987; 4,274,644, Taylor, Jun. 23, 1981; 2,869,241, Owen, Aug. 26, 1958; and 2,661,220, Davis, Dec. 1, 1953. The Patents were discussed in Chieh et al., and will not be further discussed in the present application.
The dolly of the present invention may be used by moving companies as well as the average home owner. The dolly is easy to store, it is easy to assemble and disassemble, it is easy to manipulate into desired shapes, and it is easy to lock into the desired shapes. The dolly is very inexpensive to manufacture and ship, for the shape of the unique strut can be stacked one on top of each other, unlike Chieh et al.
The present invention is directed to a modular dolly kit that is easy to store, that is easy to assemble and disassemble, that is easy to manipulate into desired shapes, and that is easy to lock into the desired shapes. The dolly is also very inexpensive to manufacture and ship.
The modular dolly kit of the present invention is comprised of at least one strut having a first and second end, and a first, second, and third through hole; at least one first connector; a least one second connector, each first connector removably attaches to each second connector, hereinafter referred as a connector assembly, after at least two struts have been modularly assembled, each connector assembly is threaded through either the first, second, or third through holes of each respective strut; and at least one caster assembly, each caster assembly removably attaches to each connector assembly.
In a further embodiment of the present invention, the dolly might also comprise of at least one termination. Each termination shall be placed at a desired end of the dolly and shall be locked in place by each connector assembly. Each termination is used to create either a pivot point at each end of the dolly or to insert a handle or any other device needed to move the dolly from one location to another. Each termination is a planar body that defines two termination through holes. One of the termination through holes may be irregularly shaped to accommodate a handle, a post connection, a belt, or any other device that may be used to push or pull the collapsible body into a desired shape. If using a post or a handle, the post or handle can also serve the purpose of containing any object on the surface area of the modular dolly.
The present invention addresses the need in the industry of modular dollies that can be adjusted to meet the user's needs. The present invention allows a user to purchase one kit that can be used to move large, small, or oblong structures. Presently, when transporting oblong structures, usually users have to use a combination of dollies; the present invention will allow a user to assemble the dolly to the dimensions of the oblong structure.
An object of the present invention is to provide a dolly that can be collapsible.
Another object of the present invention is to provide a dolly that can be manipulated into different shapes, thereby allowing the user to transport oblong structures.
Yet another object of the present invention is to provide a dolly that can easily be assembled by the user.
A further object of the present invention is to provide a dolly that does not require tools to assemble.
Yet a further object of the present invention is to provide a modular dolly accordion kit that can be extended to the length desired by the user by simply adding modules to the dolly.
These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and drawings where:
As seen in
In another embodiment of the present invention, as seen in
In a further embodiment of the present invention, when the first connector 14a and the second connector 14b are removably connected, they lock into place after at the struts 10 are arranged into a desired position. A comparison of
In another preferred embodiment the termination members 18 are substantially planar.
In yet a another embodiment of the present invention, the first 12, second 12, and third through holes 13 of each strut 10 are approximately of the same diameter.
As seen in
An advantage of the present invention is that it provides a dolly that is collapsible.
Another advantage of the present invention is that it provides a dolly that is manipulated into different shapes, thereby allowing users to transport oblong structures.
Yet another advantage of the present invention is that it provides a dolly that is easily assembled.
A further advantage of the present invention is that it provides a dolly that does not require tools to assemble it.
Yet a further advantage of the present invention is that is provides a modular dolly kit that can be extendable by the user by simply adding modules to the dolly.
Although the present invention has been described in considerable detail in reference to preferred versions, other versions are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein.
