Description

Technical Field

[0001] The present invention relates to an awning for a cruiser mounted on an open cabin with an open upper part above the cabin of the cruiser.

Background Art

[0002] Conventionally, various cruisers have been developed that include a cabin called an open cabin, in which the upper part above the cabin is open, such as a cruiser having a main cabin equipped with a steering wheel in an open-air store style or a cruiser having a flying deck equipped with a steering wheel on the roof of the main cabin. In such a cruiser equipped with an open cabin, since the upper part above the cabin is open, open steering can be enjoyed. However, when steering in an open cabin, since it is directly exposed to strong oncoming winds, wave splashes, strong sunlight, and rain, it has been common to have an awning that covers the open cabin. As a prior art showing such a cruiser equipped with an awning, for example, there is the following Patent Document 1.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The above Patent Document 1 is an invention related to an awning for a cruiser. It divides an awning made by stretching a sheet on a frame into a plurality of parts with fiber-reinforced plastic, and joins each part of such a divided body to form an awning corresponding to various sizes, thereby achieving the merit of reducing the cost required from the manufacture of the awning to its attachment to the cruiser. However, conventional cruiser awnings, such as those shown in Patent Document 1, do not have a mechanism that allows the awning to be raised and lowered. For example, a cruiser navigating a waterway with sluice gates can only be fitted with an awning that is at a height that allows it to pass through the sluice gates, and if there is a new sluice gate other than the one whose height is known in advance, the cruiser may become unable to navigate the waterway, and the only option is to avoid it.

[0005] Therefore, the present invention aims to solve the above-mentioned problems of the conventional awning, to provide a cruiser awning that can be raised and lowered, and that can be easily retrofitted to existing cruisers. [Means for solving the problem]

[0006] To achieve the above objectives, the cruiser awning of the present invention comprises rails constituting the framework of the awning, a cover covering the rails, and a stand frame supporting the rails, wherein the stand frame is connected to a drive unit that allows the rails to be raised and lowered by driving the stand frame to rotate freely in the front-rear direction of the cruiser, and the drive unit is mountable on the edge of the cruiser, and the size of the drive unit is within the width of the edge of the cruiser. The drive unit comprises at least a base portion attached to the edge of the cruiser, a drive force generating portion positioned on the base portion, and a drive force transmission portion that transmits the drive force generated by the drive force generating portion to the stand frame. The stand frame comprises at least a front stand frame, one end of which is connected to a rail and the other end of which is rotatably connected to the front end of the base portion, and which is connected to the drive force transmission portion between the one end and the other end, and a rear stand frame, one end of which is connected to a rail and the other end of which is rotatably connected to the rear end of the base portion and which follows the movement of the front stand frame. The drive force generating portion comprises an electrically operated hydraulic cylinder, and the drive force transmission portion is connected to the front stand frame. The structure comprises a support arm rotatably connected to the base portion at a position between it and the rear stand frame, a drive force transmission arm connected to the electric hydraulic cylinder, and a drive arm connected to the front stand frame. The support arm, the drive force transmission arm, and the drive arm are formed from a single member such that the shape formed by connecting the connection points between the support arm and the base portion, the connection point between the drive force transmission arm and the electric hydraulic cylinder, and the connection point between the drive arm and the stand frame with straight lines is triangular, and the connection point of the support arm to the base portion is lower than the connection point of the drive force transmission arm to the electric hydraulic cylinder. This is its first characteristic. Furthermore, the cruiser awning of the present invention has, in addition to the first feature described above, Each of the arms—the support arm, the force transmission arm, and the drive arm—is configured with an inwardly curved shape. This is its second characteristic. Furthermore, the cruiser awning of the present invention is as described above. 1 or In addition to the two features, The thickness of the rear side of the base is greater than the thickness of the front side. This is the third characteristic. Furthermore, the cruiser awning of the present invention has, in addition to the features of any one of the first to third items above, The base portion is equipped with a cushioning member on its lower surface. This is its fourth characteristic. Furthermore, the cruiser awning of the present invention has, in addition to the features of any one of the above 1 to 4 items, The rear stand frame is constructed in an L-shape, bent toward the front stand frame. This is the fifth characteristic. Furthermore, the cruiser awning of the present invention has, in addition to the features of any one of the above 1 to 5 items, The stand frame supports the rails by suspending and fixing them on the inside of the cruiser, relative to the stand frame. This is the sixth characteristic. 。 [Effects of the Invention]

[0007] According to the cruiser awning with the first feature described above, the awning can be raised and lowered freely by equipping it with a drive unit that allows the rails to be raised and lowered. Furthermore, since the drive unit can be mounted on the edge of the cruiser, it can be an awning that can be easily retrofitted to existing cruisers. In addition, since the size of the drive unit is within the width of the edge of the cruiser, when the awning is installed, the drive unit does not protrude either inside or outside the hull, resulting in a compact, retractable awning that does not interfere with the navigation of the cruiser.

[0008] Also , electricBy using a dynamic hydraulic cylinder to generate the driving force, an awning that can be automatically raised and lowered can be made with a simple configuration. Furthermore, by forming the support arm, the driving force transmission arm, and the drive arm from a single component, the number of parts is reduced, resulting in a lightweight awning. In addition, the configuration of the support arm, driving force transmission arm, and drive arm, which are formed from a single component, is such that the shape formed by drawing straight lines from the connection points of the support arm to the base, the connection point of the driving force transmission arm to the electric hydraulic cylinder, and the connection point of the drive arm to the stand frame is triangular, and the connection point of the support arm to the base is positioned lower than the connection point of the driving force transmission arm to the electric hydraulic cylinder. As a result, the electric hydraulic cylinder generates a driving force in the forward direction, which allows the driving force transmission unit, formed from a single component, to be reliably lifted upward and rotated counterclockwise with the support arm as the fulcrum. This ensures that the driving force of the electric hydraulic cylinder is reliably transmitted via the drive arm as a force that rotates the front stand frame forward. In other words, when the electrically operated hydraulic cylinder generates forward driving force, it is possible to reliably prevent a malfunction in which the drive force transmission section, which is formed from a single component with the support arm as a pivot point, is pushed downward and rotated clockwise. Therefore, it is possible to create an awning that can reliably prevent malfunctions.

[0009] Furthermore, the above 2 According to the cruiser awning, which is characterized by the above-mentioned 1 In addition to the effects and benefits derived from its features, this design allows for weight reduction of the support arm, force transmission arm, and drive arm, all formed from a single component, and enables the creation of a retractable awning that also reduces manufacturing costs. Furthermore, the electrically operated hydraulic cylinder effectively relieves stress when force is applied to the drive force transmission section. Therefore, damage to the drive force transmission section can be prevented, resulting in a highly durable, retractable awning.

[0010] Furthermore, the above 3According to the cruiser awning, which has the characteristics described above, or second In addition to the effects of its features, when the edge of the cruiser curves and sinks towards the rear of the hull at the mounting position of the base, the horizontal alignment of the edge of the base in the longitudinal direction at the mounting position can be maintained. Therefore, it is possible to create a highly durable, retractable awning that allows for smooth lifting and lowering without being hindered.

[0011] Furthermore, the above 4 According to the cruiser awnings based on their characteristics, the above 1st to 1st 3 In addition to the effects of any one of the above features, when the edge of the cruiser curves and sinks towards the rear of the hull at the mounting position of the base, the horizontal position of the edge of the base in the longitudinal direction at the mounting position can be maintained even more effectively, resulting in a retractable awning that is less likely to be hindered in its raising and lowering operation. Furthermore, since the height of the edge of the cruiser is lower on the outside of the hull than on the inside of the hull to prevent seawater from entering the hull, the cushioning member can maintain the horizontal position of the edge of the base in the short direction at the mounting position. This allows the perpendicularity of the edges of the front and rear stand frames to the horizontal line to be maintained, resulting in a retractable awning that is less likely to be hindered in its raising and lowering operation. Therefore, it is possible to create a retractable awning that is less prone to interference during lifting and lowering, allows for smoother lifting and lowering, and is more durable.

[0012] Furthermore, the above 5 According to the cruiser awnings based on their characteristics, the above 1st to 1st 4 In addition to the effects of any one of the above features, it is possible to reliably prevent the rear stand frame from coming into contact with the drive unit. Therefore, it is possible to create a highly durable, retractable awning that is less prone to interference with the lifting and lowering operation and allows for smooth lifting and lowering.

[0013] Furthermore, the above 6According to the ownership of the cruiser by the features, in addition to the effects of any one of the above first to 5 In addition to the effects of any one of the features, the rails and the cover can be stored inside the ship rather than in the stand frame. Therefore, the rails and the cover do not protrude outside the hull, and a liftable opening that does not interfere with the navigation of the cruiser can be provided. Further, a structure that allows only the rails and the cover to be easily replaced can be adopted.

Modes for Carrying Out the Invention

[0015] The following description of a cruiser awning according to an embodiment of the present invention will be explained with reference to the drawings to facilitate understanding of the invention. However, the following description is not intended to limit the present invention as described in the claims. In Figure 5, for the sake of clarity, areas that should originally be shown with dashed lines will be shown with solid lines.

[0016] As shown in Figure 1, the awning 2 of the cruiser 1 according to an embodiment of the present invention is an electrically operated, retractable awning attached to the cruiser 1.

[0017] This awning 2 consists of a rail 10, a cover 20, a stand frame 30, and a drive unit 40.

[0018] The rail 10 constitutes the framework of the awning 2. In this embodiment, as shown in Figure 4, a configuration is used in which multiple rails are assembled in a grid pattern in the vertical and horizontal directions, and an arc-shaped rail is connected to the end in the longitudinal direction, resulting in a roughly oval-shaped rail. Of course, this configuration is not the only one, and the number, arrangement, and thickness of the rails can be changed as appropriate. The rail 10 is made of stainless steel poles, and for example, a commonly used awning rail can be used.

[0019] The cover 20 is a water-resistant sheet positioned above the rail 10 so as to cover the entire rail 10, and is tied to the rail 10 at appropriate points with strings (not shown). This cover 20 serves to block seawater, rain, and sunlight, and for example, a commonly used awning cover can be used.

[0020] The stand frame 30 is primarily for supporting the rail 10. In this embodiment, as shown in Figures 1 to 5, the cruiser 1 is equipped with a pair of stand frames on the left and right sides of its hull: a front stand frame 31 positioned on the front side of the cruiser 1 and a rear stand frame 32 positioned on the rear side of the cruiser 1. Furthermore, in addition to supporting the rail 10, the front stand frame 31 also has the function of allowing the rail 10 to be raised and lowered via the driving force of the drive unit 40. As shown in Figures 1, 2(a), and 5, one end of the front stand frame 31 is connected (fixed) to the rail 10 by a clamp 31b provided at the tip of the connecting arm 31a, and the other end is rotatably connected to the front end of the drive unit 40 via a bolt and nut, and is also connected (fixed) to the drive unit 40 between the one end and the other end. Furthermore, the rear stand frame 32 is connected (fixed) to the rail 10 at one end by a clamp 32b provided at the tip of the connecting arm 32a, and the other end is rotatably connected to the rear end of the drive unit 40 via a bolt and nut, and is a stand frame that moves in accordance with the movement of the front stand frame 31. Moreover, as shown in Figures 1(b), 2(a), and 5, the rear stand frame 32 is configured in an L-shape that is bent toward the front stand frame 31 in order to prevent contact with the drive unit 40 during operation. Furthermore, as shown in Figure 4, the front stand frame 31 and the rear stand frame 32 are configured to support the rail 10 at the same height via clamps 31b and 32b, on the inside of the cruiser 1, relative to each stand frame. The stand frame 30 is made of stainless steel poles, and for example, a stand frame commonly used for awnings can be used.

[0021] The drive unit 40 is designed to allow the rail 10 to be raised and lowered by driving the stand frame 30 so that it can rotate in the front-rear direction of the cruiser 1. This drive unit 40 consists of a base portion 41, a cover 42, a drive force generating portion 43, a drive force transmission portion 44, and a cushioning member 45.

[0022] The base portion 41 serves as the base for the drive unit 40. In this embodiment, as shown in Figures 2, 3, and 5, the base portion 41 is formed from a substantially flat stainless steel member with a hollow interior. Furthermore, as partially shown in Figure 3(b), the upper surface of the base portion 41 is provided with connecting portions 41a at both longitudinal ends for connecting the stand frame 30 via bolts and nuts. Furthermore, as shown in Figures 3 and 4, the base portion 41 is configured such that the length in the shorter direction (width) is within the length in the shorter direction (width) of the edge 3 of the cruiser 1. Furthermore, in this embodiment, as shown in Figure 2, the thickness of the rear side of the base portion 41 is made greater than the thickness of the front side. In this embodiment, the thickness of the rear side of the base portion 41 is made greater than the thickness of the front side by welding an elongated triangular stainless steel member with a hollow interior to the rear side only of the base portion 41, which has a base of a certain thickness. Of course, the configuration in which the thickness of the rear side of the base portion 41 is greater than the thickness of the front side is not limited to this configuration and can be changed as appropriate. Also, the ratio in which the thickness of the rear side of the base portion 41 is greater than the thickness of the front side can be changed as appropriate according to the shape and slope of the edge 3 of the cruiser 1.

[0023] The cover 42 is positioned on the base portion 41 and is intended to prevent the drive force generating portion 43 and the drive force transmission portion 44 from being too exposed to the outside. In this embodiment, as shown in Figures 1(b) and 2(a), a pair of thin stainless steel plates are fixed to the base portion 41 by welding. The rear side is inclined to prevent contact with the rear stand frame 32, and the front side is notched in a curved shape to prevent contact while exposing a part of the drive force transmission member 44. In addition, a thin stainless steel plate is fixed to the top and rear inclined portion between the pair of thin plates by welding, thereby closing the top and rear inclined portion. Note that the shape, thickness, material, etc. of the cover 42 are not limited to those of this embodiment and can be changed as appropriate.

[0024] The driving force generating unit 43 is positioned on the base portion 41 and within the length (width) of the base portion 41 in the shorter direction, and is for generating a driving force to drive the front stand frame 31 so that it can rotate freely in the front-rear direction of the cruiser 1. In this embodiment, the driving force generating unit 43 is configured as a so-called electric hydraulic cylinder, which consists of a motor 43a, a cylinder 43b, and a piston 43c, as shown in Figure 5. As an electrically operated hydraulic cylinder, for example, a commercially available MiniMotion (product name "MMP3-A2D150AA-DLMO") manufactured by KYB Corporation can be used.

[0025] The drive force transmission unit 44 is positioned on the base unit 41 and within the length (width) of the base unit 41 in the shorter direction, and is for transmitting the drive force generated by the drive force generation unit 43 to the front stand frame 31. In this embodiment, as shown in Figure 5, the drive force transmission unit 44 is composed of a support arm 44a, a drive force transmission arm 44b, and a drive arm 44c.

[0026] The support arm 44a constitutes the so-called pivot point of the drive force transmission unit 44, and is an arm that is rotatably connected to the base unit 41 via bolts and nuts at a position between the front stand frame 31 and the rear stand frame 32 on the base unit 41.

[0027] The aforementioned force transmission arm 44b constitutes the so-called point of force application of the force transmission unit 44, and is an arm connected to the piston 43c of the electric hydraulic cylinder via a bolt and nut.

[0028] The aforementioned drive arm 44c constitutes the so-called point of application of the drive force transmission unit 44 and is an arm connected to the front stand frame 31. In this embodiment, as shown in Figure 5, the drive arm 44c is composed of two arms: a first arm equipped with a clamp 44d at its tip for connecting (fixing) the front stand frame 31, and a second arm that is flexibly connected to the first arm via bolts and nuts. Of course, the configuration of the drive arm 44c is not limited to this configuration and can be changed as appropriate. Furthermore, the connection position between the clamp 44d and the front stand frame 31 is not limited to the position in this embodiment; it can also be moved to a position higher or lower than the position in this embodiment. In other words, in this embodiment, a single drive arm 44c is formed by two arms: a first arm and a second arm that is flexibly connected to the first arm. This configuration allows for a variable connection position between the clamp 44d and the front stand frame 31. Therefore, by varying the connection position between the clamp 44d and the front stand frame 31, the rotation range of the front stand frame 31 can be varied. More specifically, if the connection is made higher than the position in this embodiment, the front stand frame 31 rotates further forward than in the configuration of this embodiment, and the rail 10 descends deeper. On the other hand, if the connection is made lower than the position in this embodiment, the front stand frame 31 rotates less forward than in the configuration of this embodiment, and the rail 10 descends shallower.

[0029] Furthermore, in this embodiment, as shown in Figure 5(b), the support arm 44a, the drive force transmission arm 44b, and the drive arm 44c are formed from a single stainless steel thin plate member, where the connection point between the support arm 44a and the base portion 41, the connection point between the drive force transmission arm 44b and the electric hydraulic cylinder (piston 43c), and the connection point between the drive arm 44c and the front stand frame 31 are the vertices, and the shape formed by connecting these points with straight lines is triangular. In other words, in this invention, the support arm 44a, the drive force transmission arm 44b, and the drive arm 44c, all composed of a single member, rotate simultaneously and integrally due to the drive force generated in the drive force generation unit. Moreover, as shown by the dashed and double-dotted lines in Figure 5(b), the connection point of the support arm 44a to the base portion 41 is positioned lower than the connection point of the drive force transmission arm 44b to the electric hydraulic cylinder (piston 43c). Furthermore, the term "single member" in this invention is a concept that includes configurations in which the support arm, the drive force transmission arm, and the drive arm are each formed from multiple members, such as when two arms in this embodiment form one drive arm 44c, as long as the support arm, the drive force transmission arm, and the drive arm move (rotate) simultaneously and integrally due to the drive force generated in the drive force generating unit. Furthermore, in this embodiment, as shown in Figure 5, each of the support arm 44a, the driving force transmission arm 44b, and the driving arm 44c is configured with a curved shape that is recessed inward.

[0030] The cushioning member 45 is positioned within the length (width) of the edge 3 and is attached to the lower surface of the base 41 in order to maintain the horizontal alignment of the edge 3 of the cruiser 1 of the drive unit 40 (base 41) in the longitudinal direction and the horizontal alignment of the edge 3 of the cruiser 1 of the drive unit 40 (base 41) in the short direction. In addition, it is attached to the lower surface of the base 41 in order to effectively distribute the load of the drive unit 40 on the edge 3 and the load generated during lifting and lowering. Specifically, as partially shown in Figures 2 and 3(b), a cushioning member 45 is attached to the lower surface of the base portion 41 via a caulking adhesive. Furthermore, in this embodiment, the cushioning material 45 is configured to be a sheet of urethane with a uniform thickness before being attached, and the base portion 41 is attached to the edge 3 via bolts after being attached, so that a difference in thickness is naturally created in the cushioning member 45 due to the inclined shape of the edge 3 and the weight of the awning 2, thereby enabling the drive unit 40 (base portion 41) to maintain horizontality in the longitudinal and transverse directions of the edge 3 of the cruiser 1. Specifically, as shown in Figures 1 and 2, the edge 3 of the cruiser 1 has a shape that curves and sinks towards the rear of the hull. By attaching the cushioning member 45 to the lower surface of the base portion 41, the horizontal position of the edge 3 of the base portion 41 in the longitudinal direction can be maintained, as shown by the dashed line in Figure 2. Furthermore, as shown in Figures 3(b) and 4(b), the edge 3 of the cruiser 1 is lower on the outside than on the inside of the hull to prevent seawater from entering the hull. By attaching the buffer member 45 to the underside of the base portion 41, the horizontal position of the edge 3 of the base portion 41 in the short-side direction can be maintained, as shown by the dashed line in Figure 3(b). This prevents the forward stand frame 31 and the rear stand frame 32 from tilting outwards due to the inclination of the edge 3 in the short-side direction, and maintains the perpendicularity (shown as a single dashed line in Figure 3(b)) of the edge 3 of the forward stand frame 31 and the rear stand frame 32 with respect to the horizontal line (shown as a dashed line in Figure 3(b)). Furthermore, the cushioning material 45 is not limited to sheet-shaped urethane; other materials with cushioning properties may also be used.

[0031] As described above, in this embodiment, the drive unit 40 is designed to be mountable on the edge 3 of the cruiser 1, and the size of the drive unit 40 is within the width of the edge 3 of the cruiser 1.

[0032] Next, referring to Figure 5, we will explain the movement of raising and lowering the rail 10 in the awning 2 having the configuration described above. In the following explanation, we will first describe the movement of lowering the rail 10 while referring to Figure 5. First, the switch for the electric hydraulic cylinder used for lowering is turned on, driving the motor 43a. As a result, as shown in Figure 5(b), the piston 43c is gradually pushed out from the cylinder 43b, and the piston 43c pushes the force transmission arm 44b forward. In this case, because the connection point of the support arm 44a to the base portion 41 is located lower than the connection point of the drive force transmission arm 44b to the cylinder 43b, the drive force transmission unit 44 begins to rotate counterclockwise while being lifted upward, with the connection point of the support arm 44a to the base portion 41 as the pivot point. As a result, the front stand frame 31, which is connected to the clamp 44d at the tip of the drive arm 44c, is gradually pushed forward and descends, using the connection point between the front stand frame 31 and the base portion 41 as a pivot point. This causes the rail 10, which is connected to the clamp 31b on the front stand frame 31, to descend. At this time, since the rear stand frame 32 is configured such that one end is connected to the rail 10 and the other end is rotatably connected to the rear end of the base portion 41, the clamp 32b of the rear stand frame 32 rotates counterclockwise as it descends in accordance with the movement of the front stand frame 31, and the rail 10, which is connected to the clamp 32b, also descends. Then, when the piston 43c is in its most protruding position from the cylinder 43b, the descent of the rail 10 is completed, and the rail 10 is positioned at its lowest point. On the other hand, to raise the rail 10 from this state, the switch for the electric hydraulic cylinder used for raising is turned on, and the motor 43a is rotated in the opposite direction to when lowering it, thereby initiating the movement of retracting the piston 43c into the cylinder, and the rail 10 is positioned at its highest position by the opposite movement to the lowering movement described above.

[0033] The awning 2 of the cruiser 1 according to this embodiment of the present invention, having the above configuration, provides the following effects.

[0034] By providing a drive unit 40 that allows the rail 10 to be raised and lowered, the awning 2 can be raised and lowered freely. Furthermore, since the drive unit 40 can be mounted on the edge 3 of the cruiser 1, the awning 2 can be easily retrofitted to existing cruisers. In addition, since the size of the drive unit 40 is within the width of the edge 3 of the cruiser 1, when the awning 2 is installed, the drive unit 40 does not protrude from either the inside or outside of the hull, resulting in a compact, retractable awning 2 that does not interfere with the navigation of the cruiser 1. In this way, by making the awning 2 adjustable in height, even in waterways where there are new sluice gates other than those whose heights are known in advance, navigation can be continued safely if it is possible to navigate simply by adjusting the height of the awning 2.

[0035] Furthermore, by configuring the drive force generation unit 43 with an electrically operated hydraulic cylinder, the awning 2 can be automatically raised and lowered with a simple configuration. In addition, by forming the support arm 44a, the drive force transmission arm 44b, and the drive arm 44c from a single component, the awning 2 can be made lighter with fewer parts. Furthermore, the configuration of the support arm 44a, drive force transmission arm 44b, and drive arm 44c, which are formed from a single member, is such that the shape formed by drawing straight lines connecting the connection points between the support arm 44a and the base 41, the connection point between the drive force transmission arm 44b and the piston 43c, and the connection point between the drive arm 44c and the front stand frame 31 is triangular, and the connection point of the support arm 44a to the base 41 is positioned lower than the connection point of the drive force transmission arm 44b to the piston 43c. As a result, the electric hydraulic cylinder generates a forward driving force through the movement of the piston, which allows the drive force transmission unit 44, formed from a single member, to be reliably rotated while being lifted upward counterclockwise with the support arm 44a as the fulcrum. This ensures that the driving force of the electric hydraulic cylinder is reliably transmitted via the drive arm 44c as a force that rotates the front stand frame 31 forward. In other words, when the electric hydraulic cylinder generates forward driving force, it is possible to reliably prevent a malfunction in which the driving force transmission section 44, which is formed from a single member with the support arm 44a as the pivot point, rotates while pushing it downward in a clockwise direction. Therefore, an awning 2 can be made that can reliably prevent the occurrence of malfunctions. In other words, the reciprocating motion of the piston 43c of the drive force generating unit 43 causes the drive force transmission unit 44 connected to the drive force generating unit 43 to rotate counterclockwise or clockwise, thereby enabling the rail 10 to be raised and lowered. This simple configuration makes it possible to realize an awning 2 that can be raised and lowered automatically and without malfunctions in its raising and lowering operation.

[0036] Furthermore, by forming each of the support arm 44a, the drive force transmission arm 44b, and the drive arm 44c with an inwardly curved shape, it is possible to reduce the weight of the support arm 44a, the drive force transmission arm 44b, and the drive arm 44c, which are formed from a single component, and to create a retractable awning 2 that reduces manufacturing costs. Furthermore, the electric hydraulic cylinder can effectively relieve the stress when force is applied to the drive force transmission unit 44. Therefore, damage to the drive force transmission unit 44 can be prevented, resulting in a highly durable, retractable awning 2.

[0037] Furthermore, by making the thickness of the rear side of the base portion 41 greater than the thickness of the front side, when the edge 3 of the cruiser 1 is curved and sinking toward the rear of the hull at the mounting position of the base portion 41, the horizontal position of the base portion 41 in the longitudinal direction of the hull at the mounting position can be maintained, making it less likely for the lifting and lowering operation to be hindered, resulting in a highly durable and retractable awning 2 that allows for smooth lifting and lowering operation. Furthermore, by using a stainless steel member with an internal cavity as the base portion 41, the awning 2 can be made lighter, allowing for a reduction in the weight of the drive unit 40. Furthermore, by providing a cover 42 to the drive unit 40, it is possible to prevent the drive force generating unit 43 and the drive force transmission unit 44 from being too exposed to the outside, thereby preventing corrosion of the drive force generating unit 43 and the drive force transmission unit 44 due to seawater and sea breeze. Furthermore, the cover 42 is constructed by welding a pair of thin stainless steel plates, each with a sloping rear side and a curved cutout front side, to the base 41, and welding a thin stainless steel plate to the top between the pair of plates and to the sloping rear side. This configuration prevents contact between the rear stand frame 32 and the cover 42, and also prevents contact between the drive force transmission member 44 and the cover 42 while exposing a portion of the drive force transmission member 44. As a result, the awning 2 is designed to be easily operated, allowing for smooth and highly durable operation.

[0038] Furthermore, by providing a buffer member 45 on the lower surface of the base portion 41, even when the edge 3 of the cruiser 1 curves and sinks towards the rear of the hull at the mounting position of the base portion 41, the horizontal position of the base portion 41 at the mounting position can be maintained more effectively, resulting in a liftable awning 2 that is less likely to be hindered during the raising and lowering operation. Moreover, since the height of the edge 3 of the cruiser 1 is lower on the outside of the hull than on the inside of the hull, the buffer member 45 can maintain the horizontal position of the base portion 41 in the short-side direction of the hull at the mounting position. This allows the verticality of the edges 3 of the front stand frame 31 and the rear stand frame 32 with respect to the horizontal line to be maintained, resulting in a liftable awning 2 that is less likely to be hindered during the raising and lowering operation. In addition, the load on the drive unit 40 that is applied to the helicopter 3, as well as the load generated during lifting and lowering, can be effectively distributed, effectively preventing damage to the helicopter 3 and the drive unit 40. Based on the above, it is possible to create a retractable awning 2 that is less prone to interference during lifting and lowering, allows for smoother lifting and lowering, and is more durable.

[0039] Furthermore, because the rear stand frame 32 is configured in an L-shape, bent toward the front stand frame 31, even when the position where the clamp 32b of the rear stand frame 32 connects to the rail 10 is directly above the drive unit 40, as shown in Figure 5(a), the rear stand frame 32 can be reliably prevented from coming into contact with the drive unit 40. Therefore, the awning 2 can be raised and lowered smoothly without being hindered, and is highly durable.

[0040] Further, the stand frame 30 composed of the front stand frame 31 and the rear stand frame 32 is configured to support the rail 10 in a state where the rail 10 is suspended and fixed inside the ship of the cruiser 1 rather than the stand frame 30. By doing so, the rail 10 and the cover 20 can be stored inside the ship rather than the stand frame 30. Therefore, the rail 10 and the cover 20 do not protrude outside the hull, and the opening 2 that can be lifted and lowered without obstructing the navigation of the cruiser 1 can be provided. Also, a structure that allows only the rail 10 and the cover 20 to be easily replaced can be provided.

[0041] Note that the number, arrangement position, etc. of the stand frame 30 are not limited to those of the present embodiment and can be changed as appropriate. For example, a configuration in which three stand frames 3 are provided on each of the left and right sides of the hull may be adopted. However, at least two stand frames 30 are required on each of the left and right sides of the hull.

Industrial Applicability

[0042] According to the present invention, since the opening can be lifted and lowered and can be easily retrofitted to an existing cruiser, the industrial applicability in the field of cruiser openings is high.
