DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and initially to FIGS. 1-3, a curtain carrier in accordance with the preferred embodiment of the present invention comprises a carrier body 10 having a first end provided with a mounting ring 11 which has an inner wall provided with a sliding face 112, a first support seat 40 having a connecting tube 42 which is inserted into the mounting ring 11 of the carrier body 10 and has an inner wall provided with an engaging hole 424, a second support seat 20 having an engaging sleeve 22 which is inserted into and closely fit in the engaging hole 424 of the connecting tube 42 of the first support seat 40, and a rolling module 30 located between the first support seat 40 and the second support seat 20 and slidably mounted between the sliding face 112 of the mounting ring 11 of the carrier body 10 and the connecting tube 42 of the first support seat 40.
The first support seat 40 has a first stop plate 41 formed on an outer wall of the connecting tube 42 and abutting the mounting ring 11 of the carrier body 10. The connecting tube 42 of the first support seat 40 has a first end abutting the second support seat 20 and a second end provided with the first stop plate 41. The engaging hole 424 of the connecting tube 42 has a first end provided with an enlarged guide slot 421 to allow entrance of the engaging sleeve 22 of the second support seat 20 and a second end provided with a radially and inwardly extending stop flange 426 to stop movement of the engaging sleeve 22 of the second support seat 20. The engaging hole 424 of the connecting tube 42 has a diameter smaller than that of the guide slot 421 and greater than that of the stop flange 426. The guide slot 421 of the connecting tube 42 has a stepped shape and has a side provided with an oblique guide face 422 to guide movement of the engaging sleeve 22 of the second support seat 20.
The second support seat 20 has a second stop plate 21 formed on an outer wall of the engaging sleeve 22 and abutting the mounting ring 11 of the carrier body 10, and the first end of the connecting tube 42 has an end face 420 abutting the second stop plate 21 of the second support seat 20. The engaging sleeve 22 of the second support seat 20 has an inner wall provided with a through hole 222. The engaging sleeve 22 of the second support seat 20 has a first end provide with a reduced insert 221 abutting the stop flange 426 of the connecting tube 42 and a second end provided with the second stop plate 21. The reduced insert 221 of the engaging sleeve 22 has a stepped shape. The reduced insert 221 of the engaging sleeve 22 is inserted through the guide slot 421 into the engaging hole 424 of the connecting tube 42 and is guided by the oblique guide face 422 of the connecting tube 42. The reduced insert 221 of the engaging sleeve 22 has a thickness smaller than that of the engaging sleeve 22 of the second support seat 20.
The mounting ring 11 of the carrier body 10 has an inside provided with a mounting hole 111 for mounting the first support seat 40 and the second support seat 20. The mounting hole 111 of the carrier body 10 is surrounded by the sliding face 112. The mounting ring 11 of the carrier body 10 is provided with two opposite retaining grooves 113 to retain the first stop plate 41 of the first support seat 40 and the second stop plate 21 of the second support seat 20 respectively. The sliding face 112 of the mounting ring 11 is located between the two retaining grooves 113. The carrier body 10 has a second end provided with a connecting plate 12. The connecting plate 12 of the carrier body 10 is formed on an outer wall of the mounting ring 11. The connecting plate 12 of the carrier body 10 has two opposite sides each provided with a reinforcing ribs 121 and has a surface provided with a limit rod 121, a through bore 123 and a hanging hole 124.
The rolling module 30 is located between the first stop plate 41 of the first support seat 40 and the second stop plate 21 of the second support seat 20 and includes a plurality of rolling balls 31.
In assembly, the connecting tube 42 of the first support seat 40 is inserted into the mounting ring 11 of the carrier body 10, and the first stop plate 41 of the first support seat 40 is retained in one of the two retaining grooves 113 of the mounting ring 11. Then, the rolling module 30 is inserted between the mounting ring 11 of the carrier body 10 and the connecting tube 42 of the first support seat 40. Then, the reduced insert 221 of the engaging sleeve 22 is inserted through the guide slot 421 into the engaging hole 424 of the connecting tube 42 and is guided by the oblique guide face 422 of the connecting tube 42. Finally, the reduced insert 221 of the engaging sleeve 22 is stopped by the stop flange 426 of the connecting tube 42, and the second stop plate 21 of the second support seat 20 is retained in the other one of the two retaining grooves 113 of the mounting ring 11, so that the rolling module 30 is located between the first stop plate 41 of the first support seat 40 and the second stop plate 21 of the second support seat 20 and is slidably mounted between the sliding face 112 of the mounting ring 11 and the connecting tube 42 of the first support seat 40.
In practice, referring to FIG. 4 with reference to FIGS. 1-3, the curtain carrier is used to attach a curtain cloth 3 to a headrail 1 via a hanging hook 2. A pivot rod 4 extends through the through hole 222 of the engaging sleeve 22 and is movable in the headrail 1 to attach the carrier body 10 to the headrail 1. The hanging hook 2 is hooked onto the hanging hole 124 of the connecting plate 12 to attach the curtain cloth 3 to the carrier body 10. Thus, when the curtain cloth 3 is pulled by a user, the carrier body 10 is moved in the headrail 1 so as to open or close the curtain cloth 3. At this time, the first support seat 40 and the second support seat 20 are rotatable relative to the mounting ring 11 of the carrier body 10 to facilitate movement of the carrier body 10. In addition, the rolling module 30 is slidably mounted between the sliding face 112 of the mounting ring 11 and the connecting tube 42 of the first support seat 40 to reduce the friction between the carrier body 10 and the first support seat 40 to facilitate rotation of the first support seat 40 relative to the carrier body 10.
Accordingly, the curtain carrier consists of a carrier body 10, a first support seat 40, a second support seat 20 and a rolling module 30, so that the curtain carrier has a simplified construction, thereby greatly decreasing the cost of fabrication. In addition, when the first support seat 40 and the second support seat 20 are combined, the reduced insert 221 of the engaging sleeve 22 is inserted through the guide slot 421 into the engaging hole 424 of the connecting tube 42 and is guided by the oblique guide face 422 of the connecting tube 42, so that the first support seat 40 and the second support seat 20 are assembled easily and quickly, thereby facilitating assembly of the curtain carrier.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
