Description
- 1. Field of the Invention
- The invention relates to a sun screen device, more particularly to a sun screen device with a flexible screen body that can be arbitrarily adjusted.
- 2. Description of the Related Art
- A conventional sun screen device, which is used for covering and uncovering a sun roof of an automobile, includes a pair of elongate slide rails, first and second shaft units, and first and second screen units.
- Each of the slide rails extends in a first direction, and has first and second rail ends that are opposite to each other in the first direction. The slide rails are spaced apart from each other in a second direction. The first end of each of the slide rails is formed with a first positioning groove. The second end of each of the slide rails is formed with a second positioning groove.
- The first shaft unit is disposed proximate to the first rail ends of the slide rails. The first shaft unit includes a first pair of seat members that are spaced apart from each other in the second direction, and a first shaft member that extends in the second direction and that has opposite shaft end portions mounted rotatably and respectively on the first pair of seat members, and a middle shaft portion between the shaft end portions of the first shaft member.
- Similarly, the second shaft unit is disposed proximate to the second rail ends of the slide rails. The second shaft unit includes a second pair of seat members that are spaced apart from each other in the second direction, and a second shaft member that extends in the second direction and that has opposite shaft end portions mounted rotatably and respectively on the second pair of seat members, and a middle shaft portion between the shaft end portions of the second shaft member.
- The first screen unit includes a first flexible screen body and a first operating member. The first flexible screen body has a securing end that is secured to the first shaft member, and a terminating end that is opposite to the securing end and that is movable in the first direction along the slide rails. The first operating member is connected to the terminating end of the first screen body, extends in the second direction, and has first and second ends coupled slidably and respectively to the slide rails. Each of the first and second ends of the first operating member is formed with a positioning protrusion.
- Similarly, the second screen unit includes a second flexible screen body and a second operating member. The second flexible screen body has a securing end that is secured to the second shaft member, and a terminating end that is opposite to the securing end and that is movable in the first direction along the slide rails. The second screen body has a mesh size different from that of the first screen body. The second operating member is connected to the terminating end of the second screen body, extends in the second direction, and has first and second ends coupled slidably and respectively to the slide rails. Each of the first and second ends of the second operating member is formed with a positioning protrusion.
- In operation, when it is desired to cover the sun roof of the automobile, the first (or second) operating member is moved such that the terminating end of the first (or second) screen body moves in the first direction along the slide rails away from the first (or second) shaft unit. Then, the positioning protrusions of the first (or second) operating member are engaged respectively to the second (or first) positioning grooves in the slide rails. At this time, when it is desired to uncover the sun roof of the automobile, the positioning protrusions of the first (or second) operating member are disengaged respectively from the second (or first) positioning grooves in the slide rails. Then, the first (or second) operating member is moved such that the terminating end of the first (or second) screen body moves in the first direction along the slide rails toward the first (or second) shaft unit.
- Although the aforementioned conventional sun screen device achieves its intended purpose, since the operating members of the screen units can only be positioned such that the first (or second) screen body either fully covers or fully uncovers the sun roof of the automobile, it is not feasible to arbitrarily control the amount of sunlight passing through the sun roof of the automobile when the aforesaid conventional sun screen device is in use.
- Therefore, the object of the present invention is to provide a sun screen device that can overcome the aforesaid drawback of the prior art.
- According to the present invention, a sun screen device comprises a pair of elongate slide rails, a shaft unit, a screen unit, a pair of cord units, and a pair of torque transmission members. Each of the elongate slide rails extends in a first direction, and has first and second rail ends that are opposite to each other in the first direction. The slide rails are spaced apart from each other in a second direction. The shaft unit is disposed proximate to the first rail ends of the slide rails. The shaft unit includes a pair of seat members and a shaft member. The seat members are spaced apart from each other in the second direction. The shaft member extends in the second direction, and has opposite shaft end portions mounted rotatably and respectively on the seat members, and a middle shaft portion between the shaft end portions. The screen unit includes a tubular roller and a flexible screen body. The tubular roller is sleeved coaxially on and is coupled co-rotatably to the middle shaft portion of the shaft member. The flexible screen body has a securing end secured to the tubular roller, and a terminating end opposite to the securing end. The terminating end of the screen body is movable in the first direction along the slide rails. Each of the cord units includes a cord spool mounted rotatably on a respective one of the shaft end portions of the shaft member, a pulley mounted rotatably on the second rail end of a respective one of the slide rails, and a pull cord wound on the cord spool, trained on the pulley, and connected to the terminating end of the screen body. Each of the torque transmission members has a first end coupled co-rotatably to the tubular roller, and a second end coupled co-rotatably to the cord spool of a respective one of the cord units. When the terminating end of the screen body is moved in the first direction along the slide rails away from the shaft unit, this results in unwinding of the screen body from the tubular roller, rotation of the tubular roller in a first angular direction, and rotation of the cord spools of the cord units in the first angular direction due to torque transmitting action of the torque transmission members. Accordingly, the pull cords of the cord units are wound on the cord spools. On the other hand, when the terminating end of the screen body is moved in the first direction along the slide rails toward the shaft unit, this results in unwinding of the pull cords of the cord units from the cord spools, rotation of the cord spools in a second angular direction opposite to the first angular direction, and rotation of the tubular roller in the second angular direction due to the torque transmitting action of the torque transmission members. Accordingly, the screen body is wound on the tubular roller.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:

- Each of the
slide rails 2 extends in a first direction, and has first andsecond rail ends 2l, 26 that are opposite to each other in the first direction. Theslide rails 2 are spaced apart from each other in a second direction transverse to the first direction. - The
shaft unit 3 is disposed proximate to thefirst rail ends 21 of theslide rails 2. In this embodiment, theshaft unit 3 includes a pair ofseat members 31 that are spaced apart from each other in the second direction, and ashaft member 32 that extends in the second direction and that has oppositeshaft end portions seat members 31, and amiddle shaft portion 323 between theshaft end portions - The
screen unit 4 includes atubular roller 41, aflexible screen body 43, a pair ofcoupling members 42, and anelongate operating member 44. Thetubular roller 41 is sleeved coaxially on and is coupled co-rotatably to themiddle shaft portion 323 of theshaft member 32. Theflexible screen body 43 has a securingend 431 that is secured to thetubular roller 41, and a terminatingend 432 that is opposite to the securingend 431 and that is movable in the first direction along the slide rails 2. Thecoupling members 42 are disposed in thetubular roller 41 and serve to couple co-rotatably thetubular roller 41 to themiddle shaft portion 323 of theshaft member 32. The operatingmember 44 is connected to the terminatingend 432 of thescreen body 43, extends in the second direction, and has opposite ends coupled slidably and respectively to the slide rails 2. - Each of the
cord units 5 includes acord spool 51, apulley 52, and apull cord 53. Thecord spool 51 of each of thecord units 5 is mounted rotatably on a respective one of theshaft end portions shaft member 32. Thepulley 52 of each of thecord units 5 is mounted rotatably on thesecond rail end 26 of a respective one of the slide rails 2. Thepull cord 53 of each of thecord units 5 has a winding section that is connected to and that is wound on thecord spool 51, an intermediate cord section that extends from the winding section and that is trained on thepulley 52, and a connecting section that extends from the intermediate cord section and that is connected to the operatingmember 44 of thescreen unit 4 such that thepull cords 53 are connected indirectly to the terminatingend 432 of thescreen body 43 via the operatingmember 44. - Each of the
torque transmission members 6 is a spiral spring member that is sleeved on theshaft member 32 and that is disposed in thetubular roller 41. In particular, each of thetorque transmission members 6 has afirst end 61 connected to a respective one of thecoupling members 42 to couple co-rotatably with thetubular roller 41, and asecond end 62 coupled co-rotatably to thecord spool 51 of a respective one of thecord units 5. Preferably, thetorque transmission members 6 are pre-tensioned so as to maintain thescreen body 43 and thepull cords 53 in a tautened state. - In operation, referring to
FIGS. 3 and 4 , when an external force is applied to the operatingmember 44 such that the terminatingend 432 of thescreen body 43 moves in the first direction along the slide rails 2 away from theshaft unit 3, as indicated by arrow (A), thescreen body 43 unwinds from thetubular roller 41. This results in rotation of thetubular roller 41 in the first angular direction, as indicated by the arrow (B), which in turn, rotates the cord spools 51 of thecord units 5 in the first angular direction due to torque transmitting action of thetorque transmission members 6. Accordingly, thepull cords 53 of thecord units 5 are wound on the cord spools 51. - Conversely, referring to
FIGS. 5 and 6 , when an external force is applied to the operatingmember 44 such that the terminatingend 432 of thescreen body 43 moves in the first direction along the slide rails 2 toward theshaft unit 3, as indicated by arrow (C), thepull cords 53 of thecord units 5 unwind from the cord spools 51. This results in rotation of cord spools 51 in a second angular direction opposite to the first angular direction, as indicated by arrow (D) , which in turn, rotates thetubular roller 41 in the second angular direction due to the torque transmitting action of thetorque transmission members 6. Accordingly, thescreen body 43 is wound on thetubular roller 41. - It is noted that when the operating
member 44 is released from the external force, the pre-tensionedtorque transmission members 6 do not serve to wind thescreen body 43 on thetubular roller 41 and only serve to prevent slackening of thescreen body 43 and thepull cords 53. Therefore, thescreen body 43 can be arbitrarily adjusted. As such, the amount of sunlight passing through the sun roof of the automobile can be controlled. - While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
