(Cross-reference of related applications)
This application claims the priority of (patent document 1) for which it applied on January 25, 2010.

      The present invention relates to a winding cover, and more particularly to a winding cover having a winding function.

      Referring to FIGS. 1 and 2, a conventional window cover 1 is rotatably disposed between two fixing members 11 spaced apart from each other, a case 12 attached between the fixing members 11, and the fixing member 11. An awning unit 13 and a winding unit 14 are provided.

      The sunshade unit 13 is wound around the rotating mandrel 131 and the rotating mandrel 131 inserted into the cavity 121 of the case 12, and can be drawn out therethrough through the insertion groove 122 of the case 12. A curtain member 132, a grip part 133 attached to an end portion of the curtain member 132, and two rotating members 134 attached to two end portions of the rotating mandrel 131 are included. The winding unit 14 is inserted into the passage 135 of the rotating mandrel 131 and surrounds the mandrel 141 fixed to one of the fixing members 11 and the mandrel 141 and at one end thereof and at the other end of the rotating member 134. A spring 142 connected to the rotating member 134 adjacent to the fixed member 11 to which the mandrel 141 is fixed.

      When the curtain member 132 is pulled out of the rotating mandrel 131 by pulling the grip part 133, the rotating mandrel 131 that rotates by this kind of movement then rotates the rotating member 134. As a result, the spring 142 is subsequently twisted, thereby accumulating the restoring force. When the curtain member 132 is released, the restoring force is used to return the rotating mandrel 131 and the rotating member 134 to their original positions so that the curtain member 132 can be re-wound around the rotating mandrel 131. .

      The mandrel 141 and the spring 142 are mounted in the passage 135 of the rotating mandrel 131. Therefore, these elements encounter limitations due to the insufficient space provided by the passage 135. For example, the size of the spring 142 is limited and, as a result, it is not possible to provide a greater restoring force to the rotating mandrel 131, the rotating member 134 and the curtain member 132. Similarly, other parts of the winding unit 14 cannot be increased in size and, therefore, it is difficult to assemble the winding unit 14 or replace any of its parts.

The outer cover wall 231 is spaced apart from the side wall 211 to match the shape of the side wall 211. The peripheral cover wall 232 surrounds the outer surface of the outer cover wall 231 and extends toward the side wall 211. The surrounding cover wall 232 and the outer cover wall 231 define a receiving space 233 in which the winding unit 4 is disposed. The second fixing member 24 is attached to the remaining one of the two ends of the case 20 using the remaining two of the fasteners 25 (that is, opposite to the end to which the connection seat 22 is attached). It is done. The second fixing member 24 has a turning hole 241 that is substantially aligned with the rotation hole 213 in the side wall 211 of the first fixing member 21.

      The sunshade unit 3 includes a rotating mandrel 31, a curtain member 32, a first rotating member 33, a second rotating member 35, a sleeving ring 34, and a grip part 36. The rotating mandrel 31 is at least partially inserted into the passage 201 of the case 20. The curtain member 32 is fixed to the rotating mandrel 31 at one end, wound on the rotating mandrel 31, and then fed out. The first rotating member 33 and the second rotating member 35 are fixed to the rotating mandrel 31, and extend through the rotating hole 213 of the first fixing member 21 and the turning hole 241 of the second fixing member 24, respectively. To support the rotation of the rotating mandrel 31. The curtain member 32 has an end portion 321 operable to extend outward from the groove 204 of the peripheral wall 202 of the case 20. A grip component 36 is attached to the end portion 321 of the curtain member 32.

      The first rotating member 33 includes a column portion 332, a joint portion 331, and a rotating portion 333. The column portion 332 extends through the rotation hole 213 of the first fixing member 21. The joint portion 331 is fixedly attached to the rotating mandrel 31. In this embodiment, the joint portion 331 is inserted into the shaft passage 311 of the rotating mandrel 31 and secured thereto, for example by having a diameter slightly smaller than the dimension of the shaft passage 311. The rotating portion 333 is disposed between the joint portion 331 and the column portion 332. In this embodiment, the pillar portion 332 has a rectangular cross section. The sleeving ring 34 is connected to the rotating portion 333 of the first rotating member 33 with a sleeve and attached in the rotating hole 213 of the first fixing member 21.

      The winding unit 4 is attached to the first fixing member 21 and includes a spring reel 41, an auxiliary wheel 43 and a spring 44. The spring reel 41 is fixed to the first rotating member 33 that rotates therewith, and is disposed between the side wall 211 and the outer cover wall 231. The auxiliary wheel 43 is rotatably connected to the mounting rod 214 of the first fixing member 21 with a sleeve. The spring 44 is wound around the auxiliary wheel 43 and fixed at one end to the spring reel 41 (this will be described in more detail later). The winding unit 4 further includes a seat 42 that can be operated to rotate the spring reel 41 as the first rotating member 33 rotates, and the seat 42 moves in unison with the first rotating member 33. In addition, the first rotating member 33 is securely housed therein. The spring reel 41 includes two wheel walls 411, a peripheral wall 412, and a tube wall 413. The wheel walls 411 are horizontally spaced apart from each other. The peripheral wall 412 interconnects the wheel wall 411 and surrounds the first rotating member 33 and has an insertion groove 415. When the curtain member 32 is unwound from the rotating mandrel 31, the spring 44 is wound around the peripheral wall 412. The tube wall 413 extends from the inside of the wheel wall 411 and is surrounded by the peripheral wall 412, and the tube wall 413 has a recess 414 formed at the distal end portion thereof.

      The auxiliary wheel 43 has a base wall 431 and a tube wall 432 protruding from the base wall 431 and through which the mounting rod 214 of the first fixing member 21 extends. Spring 44 includes a winding end segment 441 and a hook end 442. The winding end segment 441 is wound around the tube wall 432 of the auxiliary wheel 43. The hook end 442 is inserted into the insertion groove 415 of the spring reel 41. The seat 42 has a cylindrical main body 422 and a protrusion 423. The end portion of the cylindrical main body 422 is formed with an insertion groove 421 into which the column portion 332 of the first rotating member 33 is inserted. The protrusion 423 is disposed on the surface of the cylindrical main body 422 and is accommodated in the recess 414 of the tube wall 413 of the spring reel 41. When the curtain member 32 is wound around the rotating mandrel 31, most of the spring 44 is wound around the tube wall 432 of the auxiliary wheel 43.

      As shown in FIG. 3, when the curtain member 32 holds the grip part 36 and is pulled out from the rotating mandrel 31 by pulling in the direction away from the case 20, the rotating mandrel 31 has the first and second rotating members. 33 and 35 are driven to rotate, and the first rotating member 33 then causes the spring 44 to be unwound from the tube wall 432 of the auxiliary wheel 43 and wound around the spring reel 41 to restore the restoring force. The seat 42 and thus the spring reel 41 is driven to rotate to accumulate. If necessary, the grip part 36 can be detachably connected to an external part (not shown), so that the curtain member 32 can be kept in the extended state.

      When the curtain member 32 is released, the restoring force is applied to the spring reel 41, the seat 42, the first rotating member 33, the second rotating member 35 and the rotation so that the curtain member 32 can be automatically wound. Used to return the mandrels 31 to their original positions.

      The winding unit 4 cannot occupy any internal space in the sunshade unit 3, and the winding unit 4 cannot prevent the rotation of the rotating mandrel 31. Note that it is attached outside (ie, adjacent to the outer surface of the sidewall 211). Therefore, the present invention is easy to assemble and disassemble. Further, for example, the dimensions of the spring 44 can be varied as needed so that greater restoring force can be provided. Finally, both spring 44 and other parts can be easily replaced.
