Abstract

A connecting system of a multi-section housing of an electronic device comprising: shafts between first and second housing sections and between third and fourth housing sections of superposed first to fourth housing sections to enable one section to be rotated 180 degrees with respect to another section after sliding superposed housing sections apart; first hinges which connect end faces of the second and third housing sections to be able to be rotated; and second hinges which connect opposite side end faces of the first and fourth housing sections, wherein the shafts enable the second and third housing sections to be slid with respect to the first and fourth housing sections and, in the finished slid state, the first and second hinges enable the second and third housing sections and first and fourth housing sections to be rotated about the shafts while being opened to thereby form a single flat surface.

First claim

What is claimed is:

1. A connecting system of a multi-section housing which is divided into first to fourth housing sections which are superposed in that order to form a multi-section housing which can be spread open to form a single flat surface, comprising:
first connecting devices which are arranged between the first and second housing sections and between the third and fourth housing sections, and
second connecting devices which are arranged between the first and fourth housing sections and between the second and third housing sections, wherein
the first connecting devices including:
fastening parts which are fastened to the first and fourth housing sections at one end sides, and
slide-and-rotate parts which stick out from the first and fourth housing sections, which enable the first and fourth housing sections to slide from the states superposed over the second and third housing sections, then enable the first and fourth housing sections to be rotated with respect to the second and third housing sections by respectively 180 degrees to form a flat surface at other end sides, wherein
the second and third housing sections have arm parts which hold the slide-and-rotate parts in the state where the first to fourth housing sections are superposed,
the second connecting devices including:
first hinges which connect single end faces of the second and third housing sections, and
second hinges which connect end faces of the first and fourth housing sections at opposite sides to the end faces of the first hinge sides, wherein
the first connecting devices are used to make the second and third housing sections slide with respect to the first and fourth housing sections, in the fully slid state, the first connecting devices are used to make the first and fourth housing sections rotate with respect to the second and third housing sections while the second connecting devices are used to make end faces of the second and third housing sections and end faces of the first and fourth housing sections approach each other, and, when the first and fourth housing sections finish being rotated with respect to the second and third housing sections, the end faces of the second and third housing sections and the end faces of the first and fourth housing sections abut against each other to thereby form a single flat surface.

2. The connecting system of a multi-section housing according to claim 1 , wherein
the arm part at the second housing section is formed so as to be flush with the outside surface of the first housing section in the state where the first and second housing sections are superposed, and
the arm part at the third housing section is formed so as to be flush with the outside surface of the fourth housing section in the state where the third and fourth housing sections are superposed.

3. The connecting system of a multi-section housing according to claim 1 , wherein
end faces of the first and fourth housing sections at the far sides from the arm parts of the second and third housing sections are provided with leg parts of the same heights as the arm parts.

4. The connecting system of a multi-section housing according to claim 3 , wherein
the leg parts are provided with the same lengths as the arm parts with respect to the sliding direction of the first and fourth housing sections.

5. The connecting system of a multi-section housing according to claim 1 , wherein
the surface of the second housing section superposed over the first housing section is provided with a groove which allows the slide-and-rotate part to slide and, at the slide end position, to allow the slide-and-rotate part to be rotated.

6. The connecting system of a multi-section housing according to claim 5 , wherein
the first connecting devices are provided with
two slide rails which are attached to the second and third housing sections in sliding directions with respect to the first and fourth housing sections,
slide members which slide in the directions of extension of the slide rails, and
brackets with first members which are attached to the first and fourth housing sections, with other members which are attached to end faces of the slide members, and with shafts which are provided between the two members and allow the first members to be rotated with respect to the other members,
grooves being formed to hold the slide rails and allow the slide members to move.

7. The connecting system of a multi-section housing according to claim 6 , wherein,
the slide members slide in the directions of extension of the slide rails by slide pins which are attached to the two end parts of the slide members.

8. The connecting system of a multi-section housing according to claim 6 , wherein
the arm parts which are provided at the second and third housing sections are provided with holding spaces which hold the slide members in the state where the first to fourth housing sections are superposed.

9. The connecting system of a multi-section housing according to claim 5 , wherein the first connecting devices ( 10 ) are provided with
single slide rails which are attached to the second and third housing sections in sliding directions with respect to the first and fourth housing sections,
two brackets which are attached to the second and third housing sections and hold the two ends of the slide rails, and
slide members which are provided at one end sides with fastening parts to the first and fourth housing sections and which slide along the slide rails by sleeves which are provided at the side surfaces at the other end sides and which have the slide rails inserted through them, and
grooves being formed to hold the slide rails and allow the sleeves to move.

10. The connecting system of a multi-section housing according to claim 9 , wherein,
the slide rails have circular cross-sections in directions perpendicular to their longitudinal direction.

11. The connecting system of a multi-section housing according to claim 9 , wherein
holding spaces which are provided at the second and third housing sections hold the slide members in the state where the first to fourth housing sections are superposed.

12. An electronic device comprising:
first to fourth four housing sections which are superposed in this order and are connected by a connecting system of a multi-section housing to form a multi-section housing which can be spread open to form a single flat surface, and
a control device which is provided at any of the first to fourth housing sections and which displays an image of one-quarter a screen's worth of a single display image synchronized with other screens, wherein
when the connecting system of a multi-section housing is used to make the first to fourth housing sections form a single flat surface, the control device is used to make the adjoining display screens display a single image as a whole, and
the connecting system comprising:
first connecting devices which are arranged between the first and second housing sections and between the third and fourth housing sections, and
second connecting devices which are arranged between the first and fourth housing sections and between the second and third housing sections, wherein
the first connecting devices including:
fastening parts which are fastened to the first and fourth housing sections at one end sides, and
slide-and-rotate parts which stick out from the first and fourth housing sections, which enable the first and fourth housing sections to slide from the states superposed over the second and third housing sections, then enable the first and fourth housing sections to be rotated with respect to the second and third housing sections by respectively 1
