Abstract

A height adjustment device for slates with wheels, comprising a tube of round metal section (piece no. 1) at the end of which there is the thread for fixing the slate. Said regulating device also includes an internal structure (piece no. 2) of melamine of rectangular section with the necessary machining for its use, a writing surface made of metal plate (piece no. 3) punched and folded in a suitable way for its use, two circular polymer handles (piece no. 4) with metal insert and threaded. Accompanying the pieces mentioned there is also a spring (piece no. 5) made of metal wire. Finally, a metal plate (piece 6) laser cut and folded with the necessary holes for its fixation.

Description

Height adjustment device for blackboards with wheels.

The present invention, as expressed in the set forth in this specification, refers to a device of height adjustment for conference blackboards, the which has been conceived and realized in order to obtain advantages with respect to other existing means of analogous purposes.

The device is intended for conference boards with wheels are adjustable in height of one Safe and very practical way. This goal is achieved through a concrete design of the writing plate and an interior structure  Made in melamine. By pressing a small knob Threaded in melamine we managed to regulate and fix the board to the desired height

This device allows us to regulate the board at the desired height, with great ease - since only the slate iron and that greatly reduces the weight to move-, safety thanks to a spring that does not always keep the iron in the work area and quickly.

Background of the invention

Numerous devices or means are known for perform the height adjustment of a slate with wheels and that They fulfill the function perfectly.

In reference to this there are models that they work through telescopic tubes (one inside the other) - this system forces more effort as it moves all the upper set of whiteboard writing (there are systems that they incorporate a spring inside the tubes to facilitate this regulation).

Description of the invention

The device of the invention has two very marked characteristics on which the whole principle is based. It is played with the folding of the metal plate and a structure melamine interior that provides a central movement that is performs as well as acoustic reduction, and also allow fixing of the pressure elements.

The folding of the iron allows the function of guided by the internal melamine structure that moves through the inside the resulting shape of the metal plate. This melamine (fixed on the shale of the slate) has a machining which allows the fixing of the pressure knobs to fix the slate at the desired height (this knob prevents the use of any type of tool).

The movement of the metal plate is helped by a central pier that also marks the end of the race maximum and minimum. The maximum height of the board will be 190 cm and the minimum will be 170 cm. This 20 cm path can be modified during the manufacturing process if necessary.

Once the limit positions are defined, the Slate runs centered thanks to the internal structure of melamine to adopt the desired height by the end customer. its fixation is done by two knobs that press melamine against the slate plate accessible from the back from the board.

Brief Description of the Invention

Figure 1.- Shows a perspective view of the parts involved in the device described above and reason for the invention as well as an overview of the board assembled resulting

Figure 2.- Shows a perspective view of the detail of the fixing of the knob and the system of regulation of height.

Description of a preferred embodiment

In view of the commented figure, you can observe how the device is constituted by four pieces (2), (3), (4) and (5) attachable, the piece being formed (2) by a rectangular section melamine body that incorporates a machining of several drills to fix the different parts that intervene between them the fixing knob (4).

On the other hand, in the set (3) there is the existence of the slate plate which has folded that allow to move and fix the piece (2) in the desired position by means of a knob (4). This set allows to fix a spring (5) in the bottom that helps regulating the displacement of height marking the maximum position of 190 cm and the minimum position 170 cm shown in Figure 2.

The piece (4) allows the piece (3) to be fixed in the desired position without the need for any
tool.

Claims (2)

1. A height adjustment device for blackboards with wheels, comprising a round section tube metallic (part # 1) at the end of which there is the thread for the blackboard fixing. Said regulating device also includes an internal structure (part # 2) of section melamine rectangular with the necessary machining for its use, a writing surface made of metal plate (part # 3) punctured and folded adiente for use, two circular polymer handles (part # 4) with metal insert and screwed. Accompanying the cited pieces there is also a dock (piece nº 5) made of metallic wire. Finally an iron metal (part 6) laser cut and folded with holes necessary for fixing. 2. A height adjustment device for operating blackboards with wheels and according to claim 1, is formed by a writing surface made of metal plate (part # 3) punched and folded. The internal melamine structure (part # 2) that runs longitudinally inside is introduced on said surface. This melamine structure allows the fixing of one of the ends of the spring (part # 5) made of metal wire, the other end is fixed on the metal writing surface. This spring helps during the longitudinal movement of the board in the action of regulating the height for the correct writing. Alongside these mentioned and fixed parts in the internal melamine structure are the circular polymer handles (part # 4) that serve to fix the writing surface to the desired height. These pieces form a set in which the metal plate is added
(part 6), laser cut and folded, using screws. At the other end of this last piece, the round-section metal tube (part # 1) is fixed by means of a screw.
