Description

Height adjustment device for tripod boards.

The present invention, as expressed in the set forth in this specification, refers to a device height adjustment for tripod conference boards (3 support points), which has been conceived and carried out in order of gain advantages over other existing analog media Purposes

The device is intended for Tripod conference boards are adjustable in height from one Safe and very practical way. This goal is achieved through a Concrete design of the writing plate and a longitudinal hole on the narrowest side of the slate plate that we It defines the route to follow. By pressing a small threaded knob on the metal tube we managed to regulate the height of the blackboard.

This hole allows us to locate the position highest and lowest position of the board in a safe way and fast Safe since the boundary of the hole prevents the tube metallic fall and may damage the person or other material; and fast since the hole itself indicates the end of the route.

Background of the invention

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

In reference to this there are models that work by means of telescopic tubes (one inside the other) and pressure fixation - this system prevents locating the end of the inner tube with the danger that it falls, they do not have a reference of the height that you are regulating. The same system exists with screw fixing - there are also systems with specific pre-marked positions (4 or 5 positions)
- What happens if they do not conform to what is desired by the end customer? -.

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 two holes longitudinal located on the narrow sides of it (a hole on each side).

The folding of the iron allows the function of guided of the 2 front support points of the board made in a metal tube that travel inside the shape resulting from the metal plate. This metal tube has a end of a threaded hole in which a knob is fixed (this knob avoid using any type of tool). He tube movement is delimited by the longitudinal hole lateral and to the fixing of the knob.

The tubes, apart from fulfilling the function of height adjustment also provide the board with greater strength structure.

The longitudinal hole located one on each side of the board, is located at a specific position vertically so that your tour already provides us with two measures of maximum and minimum. The maximum height of the board will be 190 cm and the minimum It will be 170 cm. This 20 cm path can be modified during the manufacturing process if necessary

Once the limit positions are defined, the hole allows a uniform path along it to adopt the desired height for the final customer. His fixation is done by two knobs that press the tube against the iron of the slate accessible from the front or back of the blackboard.

Brief Description of the Invention

Figure 1.- Shows a perspective view exploded of the parts involved in the device set forth above and reason for the invention as well as the mounted slate.

Figure 2.- Shows a perspective view of the detail of the fixing of the knob and of the maximum positions and minimum

Description of a preferred embodiment

In view of the commented figure, you can observe how the device is constituted by three pieces 1, 3 and 4 attachable to each other, the piece (1) being formed by a metal body of square and tubular section in which it is located in one end a threaded hole that will serve as a housing for the knob of fixing (4).

On the other hand, in the set (3) there is the existence of the slate plate which has in the narrower sides a longitudinal hole that thanks to its folding allows to move and fix the piece (1) in position desired by means of a knob (4). This iron has this longitudinal hole in a specific area already at a specific height to default to the maximum position of 190 cm (detail A) and the minimum position 170 cm (detail B)

The piece (4) allows the fixing of the pieces (1) in the desired position without the need for any tool.

Claims (2)

1. A height adjustment device for tripod slates, comprising two front, metal tubes of square section (part # 1) at the end of which there is a through hole A third auxiliary tube (section metal square (part 2) at the end of which there are two holes interns We also found a writing surface made in metal plate (part nº 3) punched and folded in shape For use, two circular polymer handles (piece no. 4) with metal insert for threading. Accompanying These pieces also have an internal structure (part # 5) made in melanin of rectangular section in which the different pieces mentioned above. Finally two internal springs optional (part # 6) made of metallic wire. 2. A height adjustment device for tripod slates of which and according to claim 1, is formed by a writing surface made in metal plate (part # 3) punched and folded that has longitudinal holes on its sides that delimit the Tour to follow. In said surface the structure is introduced internal melanin (part # 5) that runs inside longitudinally. This melanin structure allows fixation of optional springs (part # 6) that facilitate movement of height adjustment. Together with these mentioned pieces we will place the front, metal and square section tubes (piece # 1) between the melanin structure and the surface metal and, using the circular polymer handles (part no. 4) through the through holes of said tubes, we will fix This set at the desired height. The auxiliary, metallic and square section (part # 2) we will fix it on the back of the melamine structure through its anchor points.
