A table saw assembly includes a base portion with a base work piece support surface which defines a support plane and a saw blade opening. A saw blade is positionable to extend upwardly through the saw blade opening. A first extension includes a first extension work piece support surface which is pivotable with respect to the base portion between a first position coplanar with the base work piece support surface and a second position above the support plane. A second extension includes a second extension work piece support surface which is pivotable between a third position coplanar with the base work piece support surface and a fourth position above the support plane. The table saw assembly includes a handle located above the work piece support surface and accessible by a user when the first extension is in the second position and the second extension is in the fourth position.

A piece of furniture having a convertible work surface, comprising: a lower frame suitable for supporting a surface on which a fixed part is arranged, having the fixed part a series of concave curved faces on its periphery; and a number of mobile parts having at least one convex curved face and two straight faces on the periphery thereof, said straight faces being arranged perpendicular to one another. The mobile parts are provided with means for arranging same in relation to the lower frame, in a first operating position in which the mobile parts are arranged around the fixed part, defining, together with the fixed part, a first work surface; and a second operating position in which the mobile parts are arranged on top of the fixed part, abutting along their straight faces, said mobile parts defining a second work surface.

An extendable sewing machine table which uses a tabletop with a top surface, a bottom surface and four side surfaces is described. The tabletop is supported by a frame. The tabletop is attached to a bracket and the bracket is reversibly attached to the frame using adjustable bolts. An opening for a sewing machine is defined in the top surface of the tabletop. Also shown are tabletop extenders, which have a rail. Each extender's rail is received by a channel in the corresponding tabletop side surface.

A mobile entertainment trailer, including at least one video game system disposed within the mobile entertainment trailer, at least one light disposed within the mobile entertainment trailer, a jukebox to play music within the mobile entertainment trailer, and a control panel disposed within the mobile entertainment trailer to control operation of the at least one light and the jukebox.

A height adjustable sewing machine support and storage system operates with a sewing machine, as a height adjustable working surface with storage capacity. The system comprises a supportive frame, upon which rests a work surface. A sewing machine is mounted or positioned on a height adjustable platform, which is selectively adjustable in height relative to the work surface. The height adjustable platform locks into a fixed height, coplanar or below the work surface, through selective engagement with ridged brackets. A hinged side platform hingedly articulates about the left or right edge of the work surface through a drop leaf configuration. A support bracket locks the hinged side platform into a coplanar arrangement with the work surface. A lower storage bin positions below the proximal edge of the work surface, and a plurality of shelves position below, and directly to the right or left of the work surface for storage.

A dashboard desk organizer fits on the dashboard of a vehicle providing compartments for storage. Its top and bottom can be made from a semi-stiff rubber or polymer product that, while partially stiff, can nevertheless be contoured to match the contours of the dashboards of different vehicles. The structure can be around four to five inches high with a lower lip of about an inch to keep items from sliding out. It can be from about nine to eleven inches deep with varying standard manufactured lengths sized to fit a wide range of dashboards. Alternatively, its compartments can be slanted downward in the forward direction to prevent slip out of items rather than having a lip.

A three-rows-of-ball bearings sliding rail is disclosed. An inner sliding rail body is supported in outer sliding rail bodies through three rows of support ball bearings which are arranged in parallel in a lengthwise direction of the inner sliding rail body. The three rows of support ball bearings are respectively limited within a length range of the outer sliding rail bodies via ball retainers. Each of the outer sliding rail bodies includes a bottom plate, a first side wall and a second side wall which are respectively located at two sides in a widthwise direction of the bottom plate, are integrally formed with the bottom plate and extended in a lengthwise direction of the bottom plate. The first side wall includes a first arm and a supporting part which is bent inwardly and extends horizontally from a bottom end of the first arm.
