A cylindrical winding tool 3 has three elongated members 5 obtained by splitting a cylindrical member in its axial direction into multiple pieces. The elongated members are interconnected in a hinged state in a circumferential direction by the magnet sheet. When the elongated members 5 are to be used, the elongated members 5 are placed in a spread state and arranged on the magnetically-attached object 4. When the elongated members 5 are not used, the elongated members 5 are gathered together in the circumferential direction, abutment sections 5b of the end faces of the adjacent elongated members are brought into abutment on each other and thus the cylindrical winding tool 3 having a required diameter can be formed.

An adjustment mechanism, including a first, second and third element pivotally connected to each other in series; locking means to lock the respective elements in a selected position relative to each other; and a pushbutton actuating mechanism that releases the locking means such that the elements are independently pivotal with respect to each other and release of the pushbutton actuating mechanisms re-engages the locking means.

A slope adjustable illuminated art and drafting table for drawing, writing, or impromptu sketching on large documents enables efficient access and storage of artistic or drafting supplies. The art and drafting table provides a base supported by a pair of arced legs. A work surface overlays the base. The work surface is illuminated and pivotally adjustable to slope between 0 and 35. A hinged angle adjustment bracket fastens the work surface at the desired slope. The drafting table provides modular lower drawers that are interchangeable between left and right sides of the drafting table; an extendable shelf having a longitudinal lip for retaining marking instruments; and a pair of elongated partitioned lateral trays at the lateral edges of the work surface. The partitioned lateral trays are detachable and have depressions for holding artist instruments, paints, writing instruments, and other materials used by artist and draftsmen.

This invention relates to a tilt board (1, 51, 61, 101) comprising an activity surface (3) supported by a base (5). The base comprises a front wall (7) and a rear wall (9) that extends downwardly from the activity surface by a greater distance than the front wall. The activity surface (3) comprises an activity surface surround (15) defining an aperture (17) therein and a removable activity surface insert (19) dimensioned for reception in the aperture. A plurality of interchangeable activity surface inserts (19) may be provided. The activity surface inserts (19) are also tilt adjustable relative to the remainder of the tilt board. The tilt board (1, 51, 61, 101) is provided with a circumferential flange so that the tilt board may be inserted into an aperture of a larger work surface such as a table if desired. The tilt board can be used for a range of activities, can lie flat in a larger work surface if desired, and the tilt angle can be adjusted to several angles which is highly advantageous.

A removable ruler for manual ceramic cutters which can be rotatably mounted on the base of a manual ceramic cutter and which includes a rotary platform permanently secured to the base of the cutter by a rotary shaft; and two removable lateral extensions. The platform includes securing means for the rapid coupling and subsequent uncoupling of the lateral extensions.

A system for connecting spaced components of a gas turbine engine includes connecting one end of a T-bar to each of the spaced components. One component is attached to the crossbar portion of the T-bar by trapping the crossbar between the component and a bracket. The second component is attached to the shaft portion using a hanger nut connected to the shaft portion of the T-bar and bolted to the second component. The system may be installed by attaching the crossbar portion, then advancing the first component towards the second component until the shaft portion passes through an aperture in the second component. The hanger nut is attached to the shaft portion and the second component.

Disclosed are a method and/or a system of a flippable board. In one aspect, the flippable board includes a track capable of attaching to a surface, a first hinge component and a second hinge component attached to the track, and a frame attached to the first and second hinge components along a first vertical end of the frame. The first and second hinge components allow the frame to rotate between an open position and a closed position. The flippable board further includes an adjustable left magnet and adjustable right magnet attached to the first and/or second hinge component, and at least one metal sleeve attached to a second vertical end of the frame capable of connecting to the left magnet and/or right magnet of a secondary flippable board and/or an adjustable surface magnet in order to secure the flippable board in the open and/or closed position.

A whiteboard comprises a panel, four rims and four connectors. The panel comprises a writable pre-coating layer, a foaming layer and a back plate. The each rim comprises a rim main body and a number of locking pieces. The rim main body comprises a top plate, a light filter plate, an upper plate, a side plate. The light filter plate is connected between the top plate and the upper plate by melting. An inserting plate is vertically extended outwards from the side plate. A locking plate is vertically extended downwards from the rear end of the inserting plate. The locking pieces are locked at the lower ends of the locking plates. Each of the locking pieces comprises a connecting portion at the upper position thereof. A supporting portion is formed at the lower end of the connecting portion. The each connector comprises a bottom casing and a top casing. The bottom casing comprises a bottom casing main body. The top casing comprises a top cover. A lateral plate is downwards bent and extended from the outer edge of the top cover. A sealing strip is pasted at the position of the inner edge of the sealing strip contacting the writable pre-coating layer.
