Description: BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an awning to be fit to an open cabin of a cruiser whose upper side is opened. Description of the Related Art Conventionally, there is a cruiser that has a main cabin with a steering which is opened to the air, a cruiser that has a flying deck (called a flying bridge, also) with a steering which is provided on the roof of a main cabin, and a cruiser having a cabin whose upper side is opened (hereinafter, such a cabin is referred to as an open cabin). Since such an open cabin has the upper side opened, a steersman can enjoy a refreshing sense of freedom during steering. Document US 3 370 308 discloses a sliding hard top for a cruiser. However, when steering in such an open cabin, a steersman may be exposed to a strong head wind, sprayed by the waves, or exposed to sunlight, so an enclosure is installed in the open cabin in order to enclose the steering seat and protect the steersman. There are various types of enclosures, and most of them are formed so that transparent vinyl sheets are spread via fasteners on the front face and both side faces of a main frame constructed in the form of a box on the open cabin, and a shielding sheet is spread on the top face of the main frame. Therefore, such an enclosure does not have a good external appearance since the box-shaped enclosure projects from the streamlined hull. Furthermore, the enclosure is ventilated by opening the fasteners of the transparent vinyl sheets, however, generally, the cruiser is anchored while being left exposed to rain at a marina, so that the transparent vinyl sheets may deform due to changes in temperature and other environmental conditions making the fasteners difficult to be smoothly opened and closed. SUMMARY OF THE INVENTION To solve the abovementioned problems such as a poor appearance of the enclosure and a difficulty in opening and closing the fasteners of the enclosure in the conventional art, in the present invention, a roof cover with a light shielding effect is provided so as to hang down toward the front side at the upper side of the open cabin of the cruiser, a transparent window panel is provided and inclined so as to be in parallel with said roof cover, said window panel is made to freely open and close by sliding in a space between the front end of the roof cover and the front portion of the open cabin that is provided at the front side of the roof cover, the opening and closing operability of the window panel is excellent, and in particular, when closing the window panel, the awning is made to have a streamlined form so that wind flows down forward from the window panel to the roof cover. In short, according to the invention, since the roof cover 3 having a light shielding effect is disposed so as to hang down forward at the upper side of the open cabin 2, the roof cover is in good harmony with the streamlined cruiser C, and can be used as a roof with an excellent appearance in comparison with the conventional box-shaped enclosure. In addition, air resistance against a head wind heading for the open cabin 2 is relieved by the inclination of the roof cover 3 to reduce the pitching and rolling of the cruiser C due to the head wind, whereby the steering is made excellent. Since the space X between the front end of the roof cover 3 and the front portion of the open cabin 2 is freely opened and closed by sliding the transparent window panel 4 disposed and inclined so as to be in parallel with the roof cover 3, the space X can be opened and closed by the easy operation of sliding the window panel 4 in comparison with the conventional opening and closing means by means of fasteners that are troublesome to open and close, whereby, in the condition where the window panel 4 is opened, wind can be allowed to blow in the steering sheet of the open cabin 2, and a steersman can feel a refreshing sense of freedom. Furthermore, in the condition where the window panel 4 is closed, the form becomes an excellent streamline in appearance in which inclination continues from the window panel 4 to the roof cover 3 in comparison with the conventional type, the field of view is good, and a strong head wind and the sea spray can be avoided, so that the cruiser C can be steered with no problem. A pair of parallel rods 8 and 8a disposed in parallel at the right and left are provided on the lower ends of the side frames 12 and 12a supporting the roof cover 3, and the parallel rods 8 and 8a are connected via the attaching and detaching means 24, 24a... to the handrails C1 and C1a provided at the left and right of the open cabin 2, so that the awning 1 can be attached to the existing handrails C1 and C1a without providing and fixing an attaching member exclusive for the awning 1, and the attaching work becomes easy. The awning can be easily removed from the open cabin 2 as necessary. Moreover, since the rear end of the roof cover 3 is extended so as to cover the upper side of the rear deck C4, the shading area of the roof cover 3 can be expanded not only to the steering sheet but also to the extent up to the rear deck C4, and this roof cover 3 also shields the rear deck C4 from sunlight and rain. Therefore, the practical effect of the invention is great.

Awning 1 of the present invention is mainly comprised of sheet-shaped waterproof roof cover 3 having a light shielding effect, which is disposed above open cabin 2 of cruiser C so as to hang down forward, and transparent window panel 4 which moves to open and close by sliding in space X between the front end of said roof cover 3 and the front portion of open cabin 2, and is disposed and inclined so as to be in parallel with the roof cover 3. Also, the cruiser C in the drawing is a type provided with a flying deck (open cabin 2) on the roof of the main cabin, and, needless to say, in addition to this type cruiser C, the awning 1 of the invention can be applied to other cruisers if they have open cabins without roofs. The abovementioned roof cover 3 and window panel 4 are attached to mainframe 5. The main frame 5 is formed by monolithically molding front frame 6 and rear frame 7, and as shown in Fig. 4, the mainframe is formed into a roughly lateral rectangular shape so that the frame is bilaterally symmetric and the front and rear sides curve outward in the bottom view. The front frame 6 is formed into a roughly U shape by connecting parallel rods 8 and 8a, which are disposed in parallel at the right and left sides on the same plane, and front arc rod 9, which curves outward from the front end of said parallel rods 8 and 8a. The rear ends of the parallel rods 8 and 8a are continued from bow-shaped rods 11 and 11a that are arched so as to fall forward as shown in Fig. 5, and the lower ends of said bow-shaped rods 11 and 11a are connected to the rear ends of the parallel rods 8 and 8a at almost right angles, whereby these frames and rods are united to form the mainframe 5. Furthermore, as shown in Fig. 6, in the mainframe 5, arched side frames 12 and 12a which gently curves are laid across the front ends of the parallel rods 8 and 8a and the rear portions of the bow-shaped rods 11 and 11a, and said side frames 12 and 12a are disposed in parallel with each other so as to overlap with the parallel rods 8 and 8a and the bow-shaped rods 11 and 11a. At the front ends of the side frame 12 and 12a, the connecting portions to the parallel rods 8 and 8a form short standing portions 13 and 13a. At the forward portions of the side frames 12 and 12a, the arch-shaped front frame 14 is laid. A plurality of lateral supporting rods 15 and 15... of the roof cover 3 with the same curvature as that of the front frame 14 are disposed in parallel with each other between the front frame 14 and the rear arc rod 10, vertical supporting rods 16 and 16a... are disposed so as to intersect said lateral supporting rods 15 and 15a..., and the front and rear ends of said vertical supporting rods 16 and 16a... are connected to the front frame 14 and rear arc rod 10, respectively. Herein, the roof cover 3 is spread over the curved surface surrounded by the rear arc rod 10, front frame 14, and side frames 12 and 12a. That is, each side of the roof cover 3 is turned up so as to wrap the rear arc rod 10, front frame 14, and side frames 12 and 12a, and as shown in Fig. 4, a lining spread on the back surface of the roof cover 3 and the abovementioned sides of the cover are stitched up by a string in zigzags. Then, as shown in Fig. 13, this roof cover 3 is formed by extending the rear end of the roof cover 3 so as to cover the rear deck C4 of the cruiser C in the condition where the awning 1 is attached to the cruiser C. Furthermore, as shown in Fig. 5, slide rails 17 and 17a are provided in parallel with each other under the side frames 12 and 12a to be along with the curves of the frames, and the front and rear ends of said slide rails 17 and 17a are connected to the rear portions of the standing portions 13 and 13a of the slide frames 12 and 12a and the arc rods 11 and 11a, respectively. The window panel 4 is made from plastic such as polycarbonate, has an area roughly corresponding to the space X surrounded by the front the front frame 14, front arc rod 9, and side frames 12 and 12a, and is bent horizontally into an arch shape as the front frame 14. Reinforcing frame 18 is provided on the periphery of the window panel 4, and cylindrical sliders 19 and 19a are fixed to the front and rear ends at the right and left sides of said reinforcing frame 18, and said sliders 19 and 19a are slidably mounted on the slide rails 17 and 17a, whereby the window panel4 opens and closes by sliding in the space X between the front frame 14 and the front arc rod 9 (corresponding to the space X between the front end of the roof cover 3 and the front portion of the open cabin 2). In other words, the front side 18a and rear side 18b of the reinforcing frame 18 are disposed so as to overlap with the upper portion of the front arc rod 9 and the lower portion of the front frame 14, respectively, in the condition where the space X is closed by the window panel 4 as shown in Fig. 6, and on the other hand, the window panel 4 is disposed so as to overlap the lower portion of the roof cover 3 in parallel in the condition where the space X is opened by sliding the window panel 4 rearward as shown in Fig. 8. U-shaped rear strikers 20 and 20a are provided at the middle portions of the front side 18a and rear side 18b of the reinforcing frame 18 corresponding to the lower edge and upper edge of the window panel 4 so that the strikers project forward and rearward in the direction of inclination of the window panel 4. U-shaped knob 21 for sliding operation of the window panel 4 is hung down from the middle portion of the rear side 18b of the reinforcing frame 18. In addition, the portion of the front arc rod 9 corresponding to the front striker 20 is provided with locking device 22 for locking and unlocking said striker 20. The portion of the rod corresponding to the rear striker 20a in the condition where the window panel 4 is moved rearward (corresponding to the intersection between the lateral supporting rod 15 and vertical supporting rod 16) is provided with locking device 22a for locking and unlocking the striker 20a. The locking devices 22 and 22a have the same structure, and as the schematic internal structure of one locking device 22 shown in Fig. 10, the locking device is comprised of latch 23 for attaching and detaching the strikers 20 and 20a and lever 23a for attaching and detaching operations of the strikers 20 and 20a with said latch 23. The latch 23 is forked so as to retain the strikers 20 and 20a, provided in a manner enabling the latch to freely rotate, and pressed in the direction of releasing the strikers 20 and 20a by a twist coil spring. On the other hand, the lever 23a is provided so that the front end is freely engaged and disengaged with one of the abovementioned forks, and pressed in the direction of engaging with the fork of the latch 23 by a twist coil spring. When the latch 23 rotates while retaining the striker 20 or 20a between the forks, one of the forks engages the front end of the lever 23a, the locking devices 22 and 22a retains the strikers 20 and 20a, and in this condition, the base end of the lever 23a is swung so as to disengage the fork, whereby the latch 23 rotates in the releasing direction by the pressing force of the twist coil spring to release the strikers 20 and 20a from the locking devices 22 and 22a. Also, as shown in Fig. 9, the existing bar-shaped handrails C1 and C1a are fixed to the right and left edges of the open cabin 2 of the cruiser C in a horizontal manner with respect to the open cabin 2, and awning 1 is connected to the handrails C1 and C1a via attaching and detaching means 24, 24a... comprised of clamps. Concretely, parallel rods 8 and 8a on the main frame 5 that are provided at a space corresponding to the space between the handrails C1 and C1a are disposed in parallel with each other by the clamps 24, 24a... so as to overlap the handrails C1 and C1a. As shown in Fig. 11, the clamps 24, 24a... connect the upper clamp 25 clamping the parallel rod 8 or 8a and lower clamp 26 clamping handrail C1 or C1a via U-shaped joint 27. The upper clamp 25 and lower clamp 26 have almost the same structure and are formed of upper plates 28 and 28a and lower plates 29 and 29a in pairs, respectively, and in the lower surfaces of the upper plates 28 and 28a and the upper surfaces of the lower plates 29 and 29a, semicircular concave portions corresponding to the arcs of the parallel rods 8 and 8a or the handrails C1 and C1a are made, respectively, and female screws that communicate both ends of the upper plates 28 and 28a and lower plates 29 and 29a are threaded. Then, the parallel rods 8 and 8a and handrails C1 and C1a are disposed between the concave portions of the upper plates 28 and 28a and lower plates 29 and 29a of the upper clamp 25 and lower clamp 26, and bolts B are screwed into the female screws in the upper plates 28 and 28a and the lower plates 29 and 29a, whereby the parallel rods 8 and 8a and handrails C1 and C1a are clamped by the upper clamp 25 and lower clamp 26 to connect the parallel rods 8 and 8a and the handrails C1 and C1a. Thereby, as shown in Fig. 9, the awning 1 is fixed to the open cabin 2, and in the condition where the window panel 4 is closed, the space X is closed by the front face upper edge of windproof panel C2 provided on the periphery of the open cabin 2 and the front end of the roof cover 3. Furthermore, at the front side of the open cabin 2, strut C3 that connects and supports the front arc rod 9 on the main frame 5 is erected. Depending on the type of the cruiser C, the cruiser may not have the existing handrails C1 and C1a, and in this case, the strut C3 is erected around the open cabin 2 to connect and support the front arc rod 9 and the parallel rods 8 and 8a on the main frame 5. Next, the action of the awning 1 of the present invention is explained. When windproofing is not necessary, handle 21 attached to the window panel 4 is gripped, the window panel 4 is slid rearward until the rear striker 20a attached to the window panel 4 (reinforcing frame 18) is locked by the rear lock device 22a, and the space X between the front end of the roof cover 3 and the front part of the open cabin 2 (the front face upper edge of the windproof panel C2) is closed. Since the roof cover 3 is extended so that the rear end covers the upper side of the rear deck C4 of the cruiser C, the area including the steering sheet of the open cabin 2 up to the deck C4 is shaded.
