Description

Rolling whiteboard with fixed eraser

The present invention relates to a whiteboard, and in particular to a scrolling whiteboard with a fixed eraser that automatically and circularly scrolls a soft whiteboard through a scrolling shaft to extend the writing surface of the whiteboard infinitely and automatically clears written content through a fixed eraser.

The known whiteboard structure is to fix the whiteboard on the supports on both sides, and a storage tray for placing whiteboard markers and blackboard erasers is provided below it. Wherein, both the whiteboard and the storage tray are fixed on the bracket by riveting or screw locking.

However, during the use of such a whiteboard, such as a company meeting or classroom teaching, it is often necessary to face the lack of space for writing halfway through the writing, so that the user must stop writing content, and hold the eraser to clean up the written content before continuing to write.

Moreover, the writing space of traditional whiteboards is often limited by the size of the whiteboard and the size of the placement space. Although there are reversible whiteboard designs on the market, after writing on one side, you can continue writing by flipping the whiteboard to the other side. Such a flipping process is also an extremely inconvenient experience for users.

The present invention provides a scrolling whiteboard with a fixed eraser. The purpose of this invention is to extend the available space for users to write by automatically scrolling the soft whiteboard. The eraser fixed on the side of the whiteboard can be used to wipe the written content immediately, creating an intuitive and convenient whiteboard experience, and effectively improving the shortcomings of traditional whiteboards.

A rolling whiteboard with a fixed eraser of the present invention comprises: a whiteboard frame; two scrolling shafts, which are set at two corresponding sides of the whiteboard frame with a certain distance; a soft base plate, which is wound between the two scrolling shafts, and forms a ring-shaped closed curved surface, wherein a writing surface is formed on the outside of the soft base plate; at least one support plate is arranged inside the flexible base plate and fixed on the whiteboard frame to support the writing surface; The wiping bracket is vertically pivoted on the whiteboard frame and is arranged on one side of the writing surface; wherein, the flexible substrate is rolled through the two rolling shafts to replace the writing surface.

In an embodiment of the present invention, an electric control unit is provided inside the above-mentioned whiteboard frame, and the electric control unit includes a power supply unit and at least one control switch.

In one embodiment of the present invention, a motor is provided inside the whiteboard frame, and the motor is electrically connected to the at least one control switch for controlling the rotation of the scroll shaft.

In one embodiment of the present invention, a planetary gear is arranged inside the above-mentioned whiteboard frame body, which engages with the motor to control the rotation of the scroll shaft.

In one embodiment of the present invention, the above-mentioned flexible substrate is driven by the rolling shaft to roll forward or reverse.

In one embodiment of the present invention, the above-mentioned flexible substrate can be, but not limited to, a whiteboard made of flexible magnetic material.

In one embodiment of the present invention, the above-mentioned at least one eraser bracket includes a support tube, a pinch tube and a handle. The support tube is slightly longer than the pinch tube for fixing on the whiteboard frame body, and the pinch tube is a C-shaped tubular body to form a pinch groove so that the support tube can be fixed in the pinch slot. The handle is arranged outside the pinch tube for manipulating the at least one eraser frame.

In an embodiment of the present invention, the above-mentioned clamping tube further includes a cam structure for clamping a wiping cloth to form a fixed eraser.

In one embodiment of the present invention, the above-mentioned at least one eraser bracket is disposed on the whiteboard frame through a pivot mechanism, so that the at least one eraser bracket can pivot between a first position and a second position relative to the whiteboard frame.

In one embodiment of the present invention, the above-mentioned pivoting mechanism further includes an elastic member and a chute, the elastic member pulls the at least one eraser holder so that the at least one eraser holder is normally located at one end of the chute, when the at least one eraser holder is located at the first position or the second position, the at least one eraser holder is fixed by the pulling force of the elastic member.

The effect of the present invention is that by using the scrolling shaft to slide the whiteboard left and right to create more writing space, not only can the previously written content be retained, but also the writing range of the whiteboard can always be in the middle, solving the problem that some students will be blocked due to lack of whiteboard space and write in the corner of the whiteboard, resulting in poor vision. In addition, there is a whiteboard wiping rod outside the whiteboard. When necessary, just press a button, and the whiteboard will automatically rotate a circle to easily wipe the contents of the blackboard. This solves the situation that the teacher has to walk around to wipe the whiteboard.
