Description

[Technical Field]

[0001] The present invention relates to an awning that provides protection from the sun and rain. [Background technology]

[0002] For example, awnings are known that are installed on terraces, gardens, etc. of commercial facilities such as restaurants and hotels, and of homes, to provide shade and protection from the sun and rain (see Patent Document 1: Japanese Patent Laid-Open Publication No. 2006-043430). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-043430 Summary of the Invention [Problem to be solved by the invention]

[0004] The conventional awning exemplified in Patent Document 1 allows the canvas to be deployed on both the left and right sides when viewed from the front, enabling a wider range of sun and rain protection. However, it was configured with two rollers: one for winding up the left canvas and one for winding up the right canvas. Furthermore, two operating units for deploying and retracting the left and right canvases, respectively, and two guide rails for guiding each operating unit to move up and down, were provided on both ends of the rollers in the axial direction. As such, there were issues with the large number of parts, the complex device structure, and increased costs. There was also the issue of it appearing untidy.

[0005] In response to the above problem, the inventors of the present application considered adopting a configuration in which the left and right canvases are wound around a single roller rather than separate rollers. While this configuration makes it possible to reduce the number of parts, it creates a new problem in that the height positions (unwinding positions) of the left and right canvases, which are unwound in opposite directions from a single roller, are different, giving the appearance a different, less orderly impression than before. [Means for solving the problem]

[0006] The present invention has been made in consideration of the above circumstances, and aims to provide an awning that can reduce the number of parts, simplify the device structure, reduce costs, and give an impression of order.

[0007] The present invention solves the above problems by the means described below.

[0008] The awning according to the present invention is an awning in which a sheet-like canvas is deployed to provide shade and protection from the sun, and the canvas is View from the front A first canvas is laid out on the left side and a second canvas is laid out on the right side, and a winding roller is provided for winding and unwinding the first canvas and the second canvas in a stacked manner. Extending in a parallel direction and viewed from the front a first roller rotatably disposed at a left position around which the first canvas is wound, and a second roller rotatably disposed at a right position around which the second canvas is wound, the front surface is a surface seen from a direction parallel to the central axis of the winding roller, An awning characterized in that the first roller and the second roller are arranged so that their upper surfaces are at the same height. It is characterized by:

[0009] This simplifies the device structure because a single winding roller can unroll the canvas on both the left and right sides.Furthermore, the left and right canvases, which are unwound in opposite directions from a single winding roller, can be aligned in height, giving the product a neat and tidy appearance and creating a sense of luxury.

[0010] The winding roller further comprises a first frame to which the leading end of the first canvas is fixed, a first arm having one end connected to the first frame and reciprocating the first frame to unfold and store the first canvas, a second frame to which the leading end of the second canvas is fixed, and a second arm having one end connected to the second frame and reciprocating the second frame to unfold and store the second canvas, and the other end of the first arm and the other end of the second arm are rotatably connected to an operating unit that simultaneously operates the first arm and the second arm, and a guide rail that guides the operating unit so that it can move up and down, and the operating unit is disposed at both ends of the winding roller in the axial direction, or at either end. The winding roller is provided with a biasing member that constantly biases the first canvas and the second canvas in the winding direction, and the operating unit is provided with a stopper for fixing the first canvas and the second canvas at a predetermined position against the biasing force of the biasing member; by moving the operating unit from below upward, the other end of the first arm and the other end of the second arm connected to the operating unit rise, and the first frame connected to one end of the first arm and the second frame connected to one end of the second arm move in a direction away from the winding roller, thereby unfolding the first canvas and the second canvas; by moving the operating unit from above downward, the other end of the first arm and the other end of the second arm connected to the operating unit descend, and the first frame connected to one end of the first arm and the second frame connected to one end of the second arm move in a direction approaching the winding roller, thereby storing the first canvas and the second canvas. According to this, the operating unit that performs the unfolding and stowing operations of the left-side canvas and the right-side canvas, and the guide rail that guides the operating unit so that it can move up and down, can be configured as one unit on each side in the axial direction of the winding roller, which reduces the number of parts, simplifies the device structure, and reduces costs.

[0011] Furthermore, the operating unit preferably includes a left guide roller and a right guide roller, both of which have central axes parallel to the central axis of the winding roller and rotatably abut against the left side and right side of the guide rail, and a central guide roller, both of which have central axes perpendicular to the central axis of the winding roller and rotatably abut against the front or rear side of the guide rail. With this configuration, when an operator moves the operating unit up and down, the force applied by the operator to the operating unit increases sliding resistance. This can be reduced by the central guide roller, allowing for smooth vertical movement of the operating unit. Furthermore, when an operator moves the operating unit up and down, the load applied to the operating unit from the other end of the first arm increases sliding resistance. This can be reduced by the left guide roller, allowing for smooth vertical movement of the operating unit. Similarly, the load applied to the operating unit from the other end of the second arm increases sliding resistance. This can be reduced by the right guide roller, allowing for smooth vertical movement of the operating unit.

[0012] Also, at the lower end, Viewed from the front It is preferable to further provide support legs on both the left and right sides that can be extended and retracted by sliding. This allows for easy movement as the support legs can be retracted when moving. On the other hand, the support legs can be extended when setting up, preventing the canvas from tipping over when exposed to wind and ensuring stable installation. Furthermore, the sliding extension structure gives the canvas a neat and tidy impression and creates a sense of luxury. [Effects of the Invention]

[0013] According to the present invention, it is possible to reduce the number of parts, simplify the device structure, and reduce costs, and it is also possible to realize an awning that gives an impression of order and creates a sense of luxury. [Brief explanation of the drawings]

[0014] [Figure 1] 1 is a perspective view showing an example of an awning according to an embodiment of the present invention. [Figure 2] FIG. 2 is a front view showing the example of the awning of FIG. 1. [Figure 3] FIG. 2 is a cross-sectional view of part A in FIG. [Figure 4] 2A and 2B are a front view and a plan view of part B in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view (schematic diagram) showing an example of an awning 1 according to an embodiment of the present invention, with FIG. 1(a) showing a state in which canvases 14A and 14B are unfolded (unrolled), and FIG. 1(b) showing a state in which canvases 14A and 14B are stored (wound up). FIG. 2 is a front view (schematic diagram) of the awning 1, with FIG. 2(a) showing a state in which canvases 14A and 14B are unfolded and support legs 40A and 40B are unfolded, and FIG. 2(b) showing a state in which canvases 14A and 14B are stored and support legs 40A and 40B are stored. FIG. 3 is a cross-sectional view (schematic diagram) of part A in FIG. 1. FIG. 4(a) is a front view (schematic diagram) of part B in FIG. 1, and FIG. 4(b) is a plan view (schematic diagram) thereof. For ease of explanation, arrows in the figures indicate the front-rear, left-right, and up-down directions of the awning 1. In addition, in all the drawings for explaining each embodiment, the same reference numerals are used to designate components having the same functions, and repeated explanations may be omitted. Furthermore, unless otherwise specified, general structural materials (metal, resin, wood, etc.) are used as structural materials for the device.

[0016] This awning 1 is a device that has a sheet-like canvas (made of fabric, resin, etc.) that can be deployed and stored, and provides shade and protection from the rain when the canvas is deployed. For example, it is used in commercial facilities such as restaurants and hotels, as well as on terraces and gardens in homes.

[0017] As an example configuration, the awning 1 is configured to include two posts 10A, 10B erected at the front and rear, and one winding roller 12 rotatably mounted on the upper parts of the two posts 10A, 10B (specifically, support parts 11A, 11B provided at the upper parts). Note that the awning may be configured such that decorative panels 13A, 13B are attached to the posts 10A, 10B as shown in Fig. 1, or may be configured such that decorative panels are not attached to the posts 10A, 10B as shown in Fig. 2.

[0018] The canvases provided include a first canvas 14A that is deployed on the left side when viewed from the front, and a second canvas 14B that is deployed on the right side. As shown in Figure 3, the first canvas 14A and the second canvas 14B are configured to be wound up and unwound by a single winding roller 12 with their surfaces facing each other. The winding roller 12 is fitted with a biasing member (for example, a spiral spring) (not shown) that constantly biases (i.e., applies rotational force) the first canvas 14A and the second canvas 14B in the winding direction.

[0019] Conventional awnings have been configured with two winding rollers: one for winding and unwinding the left-side canvas and another for winding and unwinding the right-side canvas. This resulted in a large number of parts and a complex device structure. The inventors of the present application addressed this issue by using a single winding roller 12 to wind and unwind the first left-side canvas 14A and the second right-side canvas 14B, rather than using separate winding rollers. This configuration did indeed reduce the number of parts and simplify the structure. However, the height positions of the first left-side canvas 14A and the second right-side canvas 14B, which are unwound in opposite directions from the single winding roller 12, differed. More specifically, their unwinding positions (positions away from the winding roller 12) differed, creating a new problem: the awning appeared unbalanced and untidy.

[0020] In contrast to this, in this embodiment, a first roller 16A is provided which is rotatably disposed on the left side of the center axis of the winding roller 12 in a front view, around which the first canvas 14A is wound, and a second roller 16B is rotatably disposed on the right side, around which the second canvas 14B is wound. Here, the first roller 16A and the second roller 16B are disposed so that their respective upper surfaces (i.e., their uppermost positions) are at the same height.

[0021] With this configuration, the first canvas 14A on the left side and the second canvas 14B on the right side can be unfolded (unrolled) and stored (rolled up) using a single winding roller 12. Furthermore, the height positions (unrolling positions) of the first canvas 14A on the left side and the second canvas 14B on the right side, which are unrolled in opposite directions from a single winding roller 12, can be aligned. This allows for a simplified device structure while still giving the impression of order and creating a sense of luxury.

[0022] Next, the awning 1 according to this embodiment is configured to include a first frame 20A to which the tip 14a of the first canvas 14A is fixed, and a first arm 22A, one end 22a of which is connected to the first frame 20A, and which deploys and retracts the first canvas 14A by reciprocating the first frame 20A (moving the one end 22a toward and away from the winding roller 12). The first arm 22A has a middle portion rotatably suspended and supported by a first hanging arm 24A, which is rotatably connected to the supports 10A and 10B. Similarly, the awning 1 is configured to include a second frame 20B to which the tip 14b of the second canvas 14B is fixed, and a second arm 22B, one end 22c of which is connected to the second frame 20B, and which deploys and retracts the second canvas 14B by reciprocating the second frame 20B (moving the one end 22c toward and away from the winding roller 12). The second arm 22B has a middle portion rotatably suspended and supported by a second suspension arm 24B that is rotatably connected to the supports 10A and 10B. In this embodiment, the first arm 22A, the first suspension arm 24A, the second arm 22B, and the second suspension arm 24B are provided on both ends of the winding roller 12 in the axial direction, respectively.

[0023] Furthermore, the other end 22b of first arm 22A is rotatably connected, and the other end 22d of second arm 22B is rotatably connected, thereby providing one operation unit 30 that simultaneously operates first arm 22A and second arm 22B, and one guide rail 32 that guides the operation unit 30 so that it can move up and down. In this embodiment, guide rails 32 are fixed to both ends of winding roller 12 in the axial direction, specifically to support columns 10A and 10B, and operation units 30 are attached so as to be able to move up and down (slide in the up and down direction) relative to each guide rail 32. As a modified example, a configuration may be adopted in which guide rails 32 and operation unit 30 are provided only on one end of winding roller 12 in the axial direction (i.e., only on one of support columns 10A and 10B) (not shown).

[0024] According to this configuration, by providing one guide rail 32 and one operating unit 30 per support (10A or 10B), both the first arm 22A and the second arm 22B can be operated, i.e., both the first canvas 14A and the second canvas 14B can be deployed and stored. Therefore, compared to conventional configurations, the number of parts can be reduced, simplifying the device structure and reducing costs.

[0025] 4(b), the operating unit 30 according to this embodiment includes a left guide roller 34 and a right guide roller 36, both of which have central axes parallel to the central axis of the winding roller 12 and rotatably contact the left side surface of the guide rail 32 (specifically, the outer surface of the member constituting the left side surface). The left guide roller 34 and the right guide roller 36 each have central axes parallel to the central axis of the winding roller 12 and rotatably contact the right side surface of the guide rail 32 (specifically, the outer surface of the member constituting the right side surface). The operating unit 30 also includes a central guide roller 38, which has a central axis perpendicular to the central axis of the winding roller 12 (strictly speaking, parallel to the perpendicular direction) and rotatably contacts at least one of the front surface (specifically, the inner surface of the member constituting the front surface) and the rear surface (specifically, the inner surface of the member constituting the rear surface) of the guide rail 32. The operating unit 30 is provided with a handle 31 that an operator can grip and operate, and a stopper 33 for fixing the operating unit 30 in a predetermined position (deployed position, retracted position).

[0026] This configuration allows the operation unit 30 to move up and down smoothly with a light force. If the operation unit 30 and the guide rail 32 were simply configured to slide (contact) with each other, sliding resistance would increase due to the load (rightward component) applied to the operation unit 30 from the other end 22b of the first arm 22A when the operation unit 30 moves up and down. However, the configuration including the left guide roller 34 can reduce this sliding resistance. Similarly, when the operation unit 30 moves up and down, sliding resistance would increase due to the load (leftward component) applied to the operation unit 30 from the other end 22d of the second arm 22B when the operation unit 30 moves up and down. However, the configuration including the right guide roller 36 can reduce this sliding resistance. Furthermore, when the operation unit 30 moves up and down, sliding resistance would increase due to the force (front-rear component) applied by the operator to the operation unit 30. However, the configuration including the center guide roller 38 can reduce this sliding resistance.

[0027] Here, the operation of the operator operating the operating unit 30 to unfold or retract the first canvas 14A and the second canvas 14B is as follows. Specifically, when changing from a retracted state (see FIGS. 1(b) and 2(b)) of the first canvas 14A and the second canvas 14B to an unfolded state (see FIGS. 1(a) and 2(a)), the operator grasps the handle 31 of the operating unit 30 and moves from bottom to top. This causes the other end 22b of the first arm 22A and the other end 22d of the second arm 22B, which are connected to the operating unit 30, to rise. At this time, due to the action of the link mechanism including the first suspension arm 24A, the first frame 20A connected to one end 22a of the first arm 22A moves in a direction away from the winding roller 12, and the first canvas 14A is unfolded. At the same time, due to the action of the link mechanism including the second hanging arm 24B, the second frame 20B connected to one end 22c of the second arm 22B moves in a direction away from the winding roller 12, and the second canvas 14B is unfolded.

[0028] On the other hand, when the first canvas 14A and the second canvas 14B are changed from an unfolded state (see FIGS. 1(a) and 2(a)) to a stowed state (see FIGS. 1(b) and 2(b)), the operator grasps the handle 31 of the operating unit 30 and moves from up to down. This causes the other end 22b of the first arm 22A and the other end 22d of the second arm 22B, which are connected to the operating unit 30, to descend. At this time, the first frame 20A connected to one end 22a of the first arm 22A moves in a direction approaching the winding roller 12 due to the action of the link mechanism including the first hanging arm 24A, and the first canvas 14A is stowed. At the same time, the second frame 20B connected to one end 22c of the second arm 22B moves in a direction approaching the winding roller 12 due to the action of the link mechanism including the second hanging arm 24B, and the second canvas 14B is stowed. As mentioned above, the winding roller 12 is provided with a biasing member that constantly biases the first canvas 14A and the second canvas 14B in the winding direction, so that the first canvas 14A and the second canvas 14B can be stored without bending and the force required to operate the operating unit 30 can be reduced.

[0029] Next, the awning 1 according to this embodiment is configured with support legs 40A and 40B at the lower end (specifically, the lower end of the posts 10A and 10B) that extend and retract by sliding to both the left and right sides when viewed from the front.

[0030] With this configuration, the support legs 40A, 40B can be retracted when moving, making it easy to move. On the other hand, the support legs 40A, 40B can be extended when setting up, preventing the first canvas 14A and the second canvas 14B from tipping over when exposed to wind, allowing for stable installation. Furthermore, the sliding extension structure gives an impression of orderliness and creates a sense of luxury. As a modified example, instead of a mobile configuration with support legs 40A, 40B, a non-mobile (fixed) configuration in which the lower ends of the posts 10A, 10B are directly buried in the ground may be used (not shown).

[0031] As described above, according to the present invention, it is possible to reduce the number of parts, simplify the device structure, and reduce costs, while also realizing an awning that gives an impression of order and exudes a sense of luxury.

[0032] The present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the scope of the present invention. [Explanation of symbols]
