Abstract

One ways of bringing diversity to human life is to change the color of their surrounding décor; benches or chairs and tables are part of the surrounding decors. The surface of the seating area, the back of benches and chairs and table tops can be built by adjoining the sides of prismatic pieces, whose height equals the width of the surfaces of seating areas, bench/chair backs and table tops with each side having a different color than the other side. The prismatic piece can be standing or rotating around the central axis, being perpendicular to its base so that by rotating each prismatic piece, the other side of it can be viewed.

Description

COLOR CHANGEABLE BENCH/CHAIR AND TABLE USING COLORED

ROTATABLE PRISMATIC FRAMES/SLATS

Field of the Invention

This invention is about benches or chairs and tables. The change in the color of the surfaces of seating areas, bench and chair backs and table tops is completely physical without any use of electricity or chemical reactions of certain elements, etc.

Background of the Invention

Diversity and changes in everyday life is one of the mental and psychological needs of human beings that saves their lives from being monotony and consequently from boredom and increases their efficiency. One of the many ways to respond to humans' needs regarding the diversity and changes in life is the strategy of changing the color of the environmental decor within which they spend a lot of time on a daily basis. This environment can be home, work environments, urban environments such as parks and bus stations and so on.

In cities, discerning municipalities tried to change the color of the benches, chairs and tables of city environments which were a part of the environment's decor; painting them a color other than their previous color after some time. Furniture manufacturers made a table that had two different colors underneath and turned up, making it possible to use the other side of the table in a different color by just turning the table. In addition, they made sofas that had covers and cushions with two different colors and when turned over to the other side, the other color could be used. All of these efforts were only aimed at responding to a part of human need for change and diversity that was mentioned earlier.

Now, the inventor intends to use rotating prismatic pieces around a central axis, perpendicular to the base, with each side in a different color than the other side on the surfaces of seating areas, bench and chair backs and table tops to make it possible to change the color of the surfaces of seating areas, bench and chair backs and table tops. Summary of the Invention

With the aim of creating the possibility of changing colors of the surfaces of seating areas, bench and chair backs and table tops, the mentioned pieces of the benches or chairs and table are arranged together by several adjacent parallel plates, each side of which is a side facet of a prism whose height is equal to the width of the bench/chair and table. Each side of the prismatic piece has a color different from the other sides. The pieces of the prism are identical and spaced along the same distance and can rotate around the central axis, perpendicular to their base. By rotating each prism piece around the central axis perpendicular to its base, the other side of the prism piece can be replaced by the previous side. There are two similar machines on the two ends of some of the prismatic pieces whose function is to change the standing state to a rotating state around the central axis perpendicular to the base and vice versa at same time for a number of prismatic pieces.

Generally, if the surfaces of seating areas, bench/chair backs and table tops are formed by placing sides of n prismatic pieces with the equilateral triangular arrangement, then 3 colors can be placed in n rows, resulting in 3ⁿ states and make colorful and different views in all the surfaces of seating areas, bench/chair backs and table tops. If, a prism piece with a square cross section is used instead of a prism piece with an equilateral triangular cross section, then 4 colors can be placed in n rows, leading to 4ⁿ states. Plate pieces are used in places where there is a shortage of space. The plate piece is the same prismatic piece with a square cross section that has two parallel lateral sides smaller than the other two sides. The two larger sides have different colors and only the two larger sides are used. If plate pieces are used instead of prismatic pieces with square cross sections, 2 different colors can be set in n rows to make 2ⁿ states.

If this invention is used in urban environments, city officials will not decide to paint benches or chairs and city tables for a long time according to their taste.

The invention under the title of "Mechanism for changing the color of the appearance of the bench/chair and table using rotatable colored prismatic pieces" consists of two parts: part one is dedicated to the design and manufacturing of prismatic parts. Part two is dedicated to the presentation of the technique that allows the possibility of changing the standing state to rotating state around the central axis perpendicular to the base and vice versa for prismatic parts.

There are a number of different solutions for the interior design of the prismatic parts. One of the simple solutions will be mentioned here. In order to make a prismatic piece with an equilateral triangle base (Fig. 2), three suitable surfaces of size 3 are required made from colored MDF, for example. Three steel profiles with square cross sections of 5. Hexagonal nuts are welded in the space between the three profiles at certain intervals. The short hexagonal rod 4 is cut and sharpened as shown in (Fig. 2). Pieces 3, 4 and 5 are connected to each other using a screw or wood glue (Fig. 2). In case of using prismatic piece (Fig. 2) in the surfaces of seating areas, bench/chair backs or table tops, the minimum distance from the center of the two prismatic pieces adjacent to each other should equal to the length of one side of the base of the prismatic piece plus 2 mm.

75 There are various techniques to make it possible to change the rotating state around the central axis perpendicular to the base of the prismatic piece to the standing state and vice versa. Here, a simple technique will be used for this purpose. Therefore, two identical machines will be designed that can be placed on both sides of the prismatic pieces (Fig. 2) or (Fig. 4) and (Fig. 5). The simultaneous operation of both machines at each end of the prismatic piece will allow the change of rotating state to standing

80 state and vice versa for each prismatic piece. The plan of the machine is shown in (Fig. 2), which includes a screw pin 12 mounted on the wing of a steep channel beam 1 1 connected by two screws and two nuts to the skeleton of the bench or the table. One long L beam 10 which is placed above the central axis of each prismatic piece is intended to be controlled by the machine (Fig. 2). Two screws 9 pass through the L beam 10; each screw 9 is restrained by two nuts 7 on both sides of the skeleton of the bench and the

85 table. Each screw 9 has a spring 8 located below the L beam. 6 is a two-piece support for the prismatic piece.

The mechanism of the machine (Fig. 2) is as follows: in order to create a standing state in the prismatic piece, it is necessary that thumb screws 12 be tightened so tightly in both machines mounted on both sides of the prismatic piece so that it can't be tightened anymore. In fact, the L beam 10 has moved by

90 the thumb screw 12 downward or towards the central axis rod of the prismatic piece and is tangent to it.

At the same time, the two springs 8 have been compressed. In order to change the standing state to rotating state around the central axis of the prismatic piece by screwing both thumb screws 12 in both machines in the opposite direction, the L beam 10 will move up wards by the compressed springs 8 and will move far from the central axis of the prismatic piece. If both thumb screws are sufficiently screwed in

95 the opposite direction, a 360 degree rotation will be provided for the prismatic piece.

In order to make a square based prismatic piece (Fig. 4), four suitable surfaces of the same size, that is size 13, are required made from colored MDF, for example. One steel profile with a square cross section of 15 is located in the space between profile 15 and the four surfaces of size 13 o suitable materials 14. For example, regarding the raw MDF, a small quadrate rod 16 is cut and sharpened at the end of profile 100 15 as shown in (Fig. 4) and is located inside profile 15. Pieces 13, 14, 15, and 16 are connected to each other using a screw or wood glue as shown in (Fig. 4) In case of using prismatic pieces (Fig. 4) on the surfaces of the seating areas, bench/chair backs and table tops, the minimum distance from the center of the two prisms adjacent to each other should equal to the length of the diameter of the base of the prismatic piece.

105 In order to create a prismatic plate piece (Fig. 5), two suitable surfaces are required with the same size, that is, size 17, made from colored MDF, for example. One steel profile with a square cross section of 18, two pieces of MDF that are placed on both sides of 17 and attached to them are needed. A short quadrate rod 19 is cut and sharpened as shown in (Fig. 5) and hinged inside profile 18. All pieces are bonded using a screw or wood glue (Fig. 5). In case of using prismatic pieces (Fig. 5) on the surfaces of

110 the seating areas, bench/chair backs or table tops, the minimum distance from the center of the two prisms adjacent to each other should equal to the length of the diameter of the base of the prismatic piece.
