TELEVISION CABINET WITH A TUBE AND FRAME ASSEMBLY MOVABLE IN VERTICAL AND HORIZONTAL PLANES

Abstract: A television cabinet is formed of a frame (3, 4) carrying a picture tube (2), which is connected to said frame (3, 4) and to the frontal half frame (1) through the tube fixing parts (14), spherical guideways (8), spherical bearing (15) letting the spherical guideways move and helping the tube (2) rotate vertically and horizontally.

Description: TELEVISION CABINET WITH A TUBE AND FRAME ASSEMBLY MOVABLE IN VERTICAL AND HORIZONTAL PLANES Hereby invention relates to a television cabinet which can rotate along both vertical and horizontal axis within a spherical bearing. In TV production, the image tube is fixed onto a front frame. TV user has to move the cabinet to left or right to get a better view of the TV picture. These motions carried out on this limited single axis do not in general provide users with a better view. The problem has been solved for computer monitors by installing monitors on a table capable to perform a cradle like motion by rotating the assembly to right hand and left-hand sides in order to prevent the reflection which is caused by the light sources in the environment and to provide user with a better view. To use such a structure in a television cabinet causes increase in packing materials as the height of TV set is thus raised, therefore less TV sets are conveyed and stored within a conveyor. Furthermore enlargement of screen sizes makes it difficult to turn aside TV sets as their weights are thus increased. In the U.S. patent 3,789,140 a structure called "Tillable Display Screen Assembly" is described. A tilting operation is performed using driving mechanism enabling only a horizontal motion. The object of hereby invention is to prevent light reflections initiated by outside light sources and to enable user to move the television tube along vertical and horizontal axis to obtain a better view. Another object of hereby invention is to keep TV cabinet height at an optimum level in order to provide safe and cost effective storage, transportation and packing conditions. In order to attain objectives thus stated, the invention has been configured in accordance with following drawings, where; Figure 1 , Front view of spherical bearing Figure 2 , Front view of carrier plate together with bearing and guideway Figure 3, Front view of spherical bearing mounted with the tube and the frame Figure 4, Side view of spherical bearing mounted with the tube and the frame Figure 5, Front view of the frame Figure 6, View showing motion in vertical axis of the tube and frame assembly within the cabinet. Figure 7, View showing motion in horizontal axis of the tube and frame assembly within the cabinet. Figure 8, View showing the connection of the main cabinet to the bearing together with tube and frame The descriptions of the parts numbered in the figures are as follows; ( 1 ) Frontal half frame (2) Tube (3) Long guideway holder (4) Short guideway holder (5) Carrier plate (6) Lower guideway (7) Upper guideway (8) Guideway (9) Frame Pin (10) Bearing bolt (11) Screw (12) Centering bearings (13) Cabinet ( 14) Tube fixing parts (15) Spherical bearing (16) Frame Bolt (17) Bearing pin (18) Cabinet bolt Frontal half frame(l) while keeping its spherical form is centered by means of the centering holes situated on the corners of the frame (Fig. 5) which is constructed of two short guideway holders (4) and two long guideway holders (3) and two guideways (8) which have the ability to rotate in vertical and horizontal planes and which are manufactured of production steel whose shape, thickness and width depend on the dimensions of the tube which will be carried. The long and short guideway holders (3 and 4) are connected to each other. The guideways are fixed to the frame after being centered. The spherical bearing (15) is formed of lower guideway (6) and upper guideway (7). Carrying plate (5) manufactured by bending iron sheet is centered on lower guideway (6) using bearing pins. (17). Upper and lower guideways (6 and 7 respectively) are fixed using bearing bolts (10) to the carrying plate (5) as such that guideway (8) remains between them. The spherical bearing (15) set formed as a frame and the tube fixing parts (14) are fixed onto the frontal half frame (1) with screw (11). Spherical bearing (15) mounted with tube (2) and frontal half frame (1) is put inside the cabinet (13), by means of the cabinet bolts (18) spassing through the carrying plate (5). Centering bearings (12) present on frontal half frame (1) prevents the tube from turning around the vertical axis to its center. The basic operational principle of the system is to turn the image tube (2) which is situated in a virtual sphere passing from the tube fixing parts, around vertical and horizontal axis passing through sphere's center, by a pushing force to be applied on the front frame. The lower and upper guideways (6 and 7) shown in figure 1 are guideways in spherical form passing through the tube fixing parts (14). The spherical guideways (8) which can slide between the lower and upper guideways (6 and 7) are the main parts providing the motion of the assembly. The said guideways (8) are connected to the frame (Figure 5) by means of frame bolts (16) and then mounted to the picture tube (2) and to the frontal half frame (1). This assembly which is put into the cabinet (13) is moving as shown in Figure 6 and 7. When the user pushes the frontal half frame (1) towards a direction the above described assembly moves easily towards the said direction.

Claims: CLAIMS A television cabinet characterized in that the said cabinet is formed of a frame (Figure 5) carrying a picture tube (2), which is connected to said frame and to the frontal half frame through the tube fixing parts (14), spherical guideways (8), spherical bearing (15) letting the spherical guideways move and helping the tube (12) rotate vertically and horizontally. 2. A television cabinet as described in claim 1, characterized in that guideways (8) tilted as such to enable vertical and horizontal motion of tubes (2) of different sizes. 3. A television cabinet as described in claims 1 and 2, characterized in that spherical bearing (15) is formed by connecting lower (6) and upper (7) guideways whose shapes enable the guideways (8) move between them. 4.
