The present invention will become more filly understood from the following detailed description and the accompanying drawings, which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
Please refer to
The inner block 10 has an assembling portion 11 formed at one side thereof for assembling with two sides of tipper and lower rails 41, 42 of the Window covering 40 and has an engaging space 12 formed at the other side thereof, wherein the engaging space 12 has a slot tunnel 121 correspondingly formed at an inner side thereof.
The connecting block 20 is assembled in the engaging space 12 of the inner block 10 so that when there are plural connecting blocks 20, the shape and the configuration of each connecting block may be formed as the same. Further, each connecting block 20 has an engaging portion 21 formed at one side thereof which faces the inner block 10, and the engaging portion 21 has a tenon 211 at an outer side thereof for engaging with the slot tunnel 121 of the engaging space 12 of the inner block 10. And, the other side of each connecting block 20 has an engaging space 22 formed thereon for engaging with the engaging portion 21, and the engaging space 22 has a slot tunnel 221 formed at an inner side thereof
The outer block 30 is assembled to one side of the connecting block 20 which is opposite to the side thereof facing the inner block 10. Moreover, the outer block 30 has an engaging portion 31 formed at one aide thereof facing the connecting block 20 for correspondingly engaging with the engaging space 22 of adjacent connecting block 20, and the engaging portion 31 has a tenon 311 formed at an outer side thereof for engaging with the slot tunnel 221 of the engaging space 22 of the connecting block 20, which is adjacent to the inner block 10.
The tenon 211 of each connecting block 20 and the tenon 311 of the outer block 30 are mounted on opposite edges or four edges of the outer side of the engaging portions 21, 31, respectively, and the tenons 211, 311 are formed to be arc protrusions which respectively have slot 212, 312 mounted on two sides thereof (as shown in
The frame 23 of each connecting block 20 and the frame 32 of the outer block 30 respectively have an indentation 231, 321, thereby the assembled removable block set 1 including the inner block 10, each connecting block 20 and the outer block 30 can be quickly disassembled through the indentations 231, 321.
An assembling portion 11 of the inner block 10 can have a protrusion outwardly extended from one side thereof for providing the inner block 10 to assemble, and the two ends of the case of the upper rail 41, the lower rail 42 of the Window covering 40 respectively have corresponding indentations, thereby through forcing the protrusion of the inner block 10 entering the indentations of the upper rail 41 and the lower rail 42 of the Window covering 40, the inner block 10 can be fixed greatly. Of course, the protrusion and the indentation can be exchanged.
The assembling portion 11 of the inner block 10 can have a screw hole 111 and the case of the upper rail 41, the lower rail 42 of the Window covering 40 can have a through hole (not shown) so that after assembling the inner block 10 and the case of the upper rail 41, the lower rail 42 of the Window covering 40, a fixing element, such as screw, can pass through the through hole and the screw hole for screwing and providing a better fixing.
Since the inner block 10, the connecting block 20 and the outer block 30 are mainly assembled on the ends of the case of the upper rail 41, the lower rail 42 of the Window covering 40, the outline thereof should be corresponded to the section of the ends of the case of the upper rail 41, the lower rail 42, no matter in any shape. For example, as shown in
Please refer to
Thereby, when buying a window covering, people can buy a standard window covering conforming to the width of the window, and if there is no conformed standard window covering, people just buy the removable block sets 1 to assemble in two ends of the upper rail and the lower rail for elongating the length of the rails until the lengths of the rails become slightly longer than the width of the window to facilitate the installation of the window covering. The following takes
When installing the window covering 40, several removable block sets 1 can be assembled in two ends of the upper rail 41 and tie two ends of the lower rail 42 of the Window covering 40. The width of the blinds 44 can be cut first for conforming to the width of the window. Furthermore, as shown in
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
