Abstract
Abstract A coupling structure for a screen with a fixing rod comprises the screen having at its end a predetermined length of an accessory section provided with a pair of rigid engaging plates, and the fixing rod having a pair of curved side walls separated by an intermediate partition for forming a pair of coupling chambers. The pair of rigid engaging plates holding the accessory section therebetween are inserted and propped within the coupling chamber. The accessory section has a length enough to cover an outer face of the side wall for obtaining a good appearance.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
A coupling structure for coupling a screen with a fixing rod, comprising a screen having at its end portion a predetermined length of an accessory section provided with a pair of rigid engaging plates, a fixing rod of generally elliptical cross-section and constituted by spaced side walls symmetrically interconnected by an intermediate partitioning wall defining with said side walls a pair of open ended coupling chambers, said pair of rigid engaging plates on the accessory section being oriented in superposed relation and disposed in one of the coupling chambers of said fixing rod in oblique disposition for continuously engaging at its opposite ends the wall of the coupling chamber within which the rigid engaging plates are disposed, said accessory section having a length beyond the fixed plates for covering the outer face of the fixing rod and for insertion in at least one of the chambers thereof.
Claim 2
Dependent Claim
147 words
A coupling structure for coupling a screen with a fixing rod, comprising a screen having at its end portion a predetermined length of an accessory section provided with a pair of rigid engaging plates, a fixing rod of generally elliptical cross-section and constituted by spaced side walls symmetrically interconnected by an intermediate partitioning wall defining with said side walls a pair of open ended coupling chambers, said pair of rigid engaging plates on the accessory section being oriented in superposed relation and disposed in one of the coupling chambers of said fixing rod in oblique disposition for continuously engaging at its opposite ends the wall of the coupling chamber within which the rigid engaging plates are disposed, said accessory section having a length beyond the fixed plates for covering the outer face of the fixing rod and for insertion in at least one of the chambers thereof.
Claim 3
Dependent Claim
33 words
A coupling structure as recited in claim 1, wherein said pair of rigid engaging plates is securely positioned on both faces of said accessory section in upper and lower relation with each other.
Claim 4
Dependent Claim
33 words
A coupling structure as recited in claim 1, wherein said pair of rigid engaging plates is securely positioned on one face of said accessory section in upper and lower relation with each other.
Claim 5
Dependent Claim
34 words
A coupling structure as recited in claim 1, wherein said pair of rigid engaging plates is securely positioned on both faces of said accessory section in both vertical and horizontal alignment with each other.
Claim 6
Dependent Claim
47 words
The coupling structure as claimed in claim 1, wherein one side wall at its free end is bent inwardly within the coupling chamber to form a bent piece and the engaging plates holding the accessory section therebetween are propped against the bent piece of the side wall.
Claim 7
Dependent Claim
41 words
The coupling structure as claimed in claim 1, wherein the accessory section has a length enough to secure the rigid engaging plates within the coupling chamber of the fixing rod to cover at least one front face of the fixing rod.
Claim 8
Dependent Claim
70 words
The structure of claim 1 wherein one or more fixing rods are used as a repeating element for consecutively combining a plurality of the screens, in which one screen with the accessory section holding the rigid engaging plates is engaged within one of the pair coupling chambers of the fixing rod while another screen with the accessory section, holding the rigid engaging plates is engaged within the other coupling chamber.
Claim 9
Dependent Claim
70 words
The structure of claim 5 wherein one or more fixing rods are used as a repeating element for consecutively combining a plurality of the screens, in which one screen with the accessory section holding the rigid engaging plates is engaged within one of the pair coupling chambers of the fixing rod while another screen with the accessory section, holding the rigid engaging plates is engaged within the other coupling chamber.
