Description

Application of Article 30, Paragraph 2 of the Patent Act As per the certificate for application of the provisions of exception to loss of novelty

The present invention relates to a sunshade. More specifically, the present invention relates to a free-standing awning.

Conventional free-standing awnings are generally in the form of parasols.

There is also a free-standing sunshade in which the sunshade (parasol) part is suspended from the tip of an arm protruding from a support and can be opened and closed (Patent Document 1). The arm is slidably connected to the column via an annular slider at its base end and can be moved up and down along the column, and is supported in the middle by an auxiliary arm rotatably attached to the top of the column. By winding up the rope and lifting the arm forward by rotating the handle, the awning is supported at a sufficient distance from the pillars so that the awning can be deployed without any trouble. Furthermore, a rope for opening and closing the awning is tied to the supporting wheel that opens and closes the awning, and after the arm is extended, the awning is expanded by pulling the rope for opening and closing the awning. This rope can be fixed by tying it to a post or some other suitable place, or the end of the rope can be wound up by turning a handle (not shown).

There is also a free-standing sunshade in which a rectangular sunshade sheet is opened only on one side of the pillar, so that the pillar can be installed in a corner of a passage, etc. (Patent Document 2).

However, in order to open a parasol-type awning, it is necessary to lift a heavy umbrella frame or sheet using ropes, wires, etc., and especially when the awning is large, a large amount of force is required. It is difficult to pull the rope by hand, and even more difficult to tie it somewhere while it is being pulled. Furthermore, when attempting to expand the sunshade, the distal end of the sunshade, which is stored in a collapsed state, closes and instantaneously creates negative pressure, which requires a large amount of force to open the sunshade.

In addition, in the case of a free-standing sunshade in which the sunshade part can be opened and closed by hanging it from the end of an arm that protrudes from a support, it is necessary to operate the arm to protrude away from the support and to deploy the sunshade separately. Therefore, it takes time and trouble to open and close. Furthermore, in order to speed up the opening/closing operation, it is necessary to increase the size of the winch and drum for winding up the operating wire, which is undesirable in terms of design and location.

Furthermore, in a structure in which a sunshade is hung from one side of a column or a sunshade sheet is extended, the support strength of the sunshade cannot be obtained by the arm, so there is a problem that the sunshade is vulnerable to gusts of wind and easily breaks.

In addition, in the case of a free-standing awning that has a pillar in the center of the awning, the usable space under the awning is divided by the pillar, making the center unusable, resulting in poor usability. For example, you cannot place a table, recliner, bed, seat, etc. across the center of the awning. Furthermore, since the awning is structured around a central support, installation locations are restricted and it cannot be installed close to walls or structures.

SUMMARY OF THE INVENTION An object of the present invention is to provide a free-standing sunshade that can project away from the support and simultaneously deploy the sunshade in one action.

In order to achieve such an object, the free-standing sunshade according to the invention according to claim 1 includes a support, an elevating slider that can be raised and lowered along the support, and a base end rotatably supported by the elevating slider. At the same time, the main arm whose tip end is a free end is connected to the main arm and the column, and rotation is applied to guide the tip side of the main arm away from the column, so that the tip side of the main arm is moved horizontally away from the column. An auxiliary arm that is suspended so as to protrude from the main arm, an opening/closing slider that slides along the main arm, a rope that changes direction at the tip of the main arm and connects the opening/closing slider and the column, and the tip of the main arm. A sunshade consisting of a sunshade frame that opens and closes in a fan-shape in the left and right directions along a main arm around a rotation center mechanism attached to the main arm, and a sunshade sheet supported by the sunshade frame, and the outermost sunshade frame of the sunshade. and a link that connects the opening/closing slider to push and expand the outermost awning frame by sliding the opening/closing slider, and by raising and lowering the lifting slider, the front end side is lifted while lifting the base end of the main arm. Tilt it forward to change it to a nearly horizontal position while at the same time opening the sunshade in a fan shape in the left and right directions, or sink the base end of the main arm and raise the tip side to change it to a nearly vertical position while simultaneously opening the sunshade in a fan shape in the left and right direction. I'm trying to close it.

Here, in the sunshade, the sunshade frames are independently rotatably supported by the rotation center mechanism at the tip of the main arm, and are pulled by the movement of the outermost sunshade frame and attached to the other sunshade frames and between them. Preferably, the sunshade sheet also has a structure that follows.

In addition, the rotation center mechanism is configured such that the base end sides of a plurality of radially arranged awning frames are rotatably connected around one common rotation center axis to open and close in a fan shape. and each sunshade frame are connected by a connecting plate with a different bending angle for each sunshade frame, and an individual rotation guide shaft is provided on the connection plate, and the individual rotation guide shaft for each sunshade frame is connected to the arc-shaped joint plate for each sunshade frame. It is preferable that the range of swing is regulated by moving within the guide hole so that the sunshade frames are arranged parallel to each other when the sunshade is closed.

Further, it is preferable that the elevating slider includes a bracket to which the base end of the main arm is rotatably attached, and an operating slider disposed below the bracket and interlocking with the bracket.

According to the device according to claim 1, by simply raising the lifting slider, the sunshade opens and closes in a fan-shape in the left and right directions and pops out forward to change to a nearly horizontal position, and by simply lowering the operating slider, the sunshade is moved in front of the support column. It can be pulled closer to the support and closed at the same time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described in detail below based on embodiments shown in the drawings. In this embodiment, the direction in which the awning leaves the support with respect to the support is referred to as the front direction, the direction in which it approaches the support is referred to as the rear direction, and the direction orthogonal to the front-rear direction is referred to as the left-right direction.

(Sunshade opening/closing mechanism (one-touch opening))
FIGS. 1 to 6 show an embodiment of the free-standing sunshade of the present invention. The free-standing sunshade according to this embodiment moves the operating slider 37 up and down along the support column 36, thereby simultaneously lifting the base end of the main arm 1, tilting the front end forward, and changing the posture to a nearly horizontal position. The sunshade 28 is opened in a fan-shape in the left-right direction, or the base end side of the main arm 1 is sunk and the distal end side is raised to change to an almost vertical posture, and at the same time, the sunshade 28 is closed in a fan-shape in the left-right direction.

That is, specifically, this free-standing sunshade lifts the sunshade 28 from one side, for example, the front, of the support column 36, and at the same time opens and closes it in a fan-shape in the left and right directions, and pops it forward to develop it into a nearly horizontal position. A pillar 36, a lifting slider 47 that is installed to be able to move up and down along the pillar 36, a main arm 1 whose base end is rotatably supported by the lifting slider 47 and whose distal end is a free end; An auxiliary arm 44 whose distal end is rotatably connected to the arm 1 and whose proximal end is rotatably attached to the column 36; an opening/closing slider 3 that slides along the main arm 1; A sunshade that opens and closes in a fan shape in the left and right direction along the main arm 1 around a rope 41 that changes direction and connects the opening/closing slider 3 and the support 36, and a rotation center mechanism 35 attached to the tip of the main arm 1. A sunshade 28 consisting of frames 5, 6, 7, 8, 9 and a sunshade sheet 21 supported by the sunshade frames 5, 6, 7, 8, 9, and the outermost sunshade frames 5 on both sides for opening and closing. It is provided with a link 4 that connects the slider 3.

In the case of this embodiment, the elevating slider 47 includes a bracket 38 that rotatably supports the base of the main arm 1, an operating slider 37 and a bracket 38 that move up and down within a height range that is easy for the user to handle, and the operating slider 37. The bracket 38 is configured to move up and down in conjunction with the movement of an operation slider 37 operated in a lower area of the support column 36. Generally, it is preferable that the position where the sunshade 28 is deployed is at a high position where it does not obstruct the user when entering in a standing position. often do not match. Therefore, in this embodiment, the operating slider 37 that interlocks with the bracket 38 is provided below the bracket 38 so that the slider does not have to be operated at a high position. Of course, the elevating slider 47 is not limited to arranging the two members of the operating slider 37 and the bracket 38 apart and integrating them with the connecting member 39, but can be configured as a one-piece structure including the operating slider 37 and the bracket 38. It goes without saying that there is nothing wrong with doing that.

The operation slider 37 moves up and down along the support column 36, and in this embodiment is made of, for example, a frame surrounding the support column 36. It is preferable that, for example, a bearing or a sliding resin block (not shown) is interposed between the operation slider 37 and the column 36 so that the slider 37 can be moved up and down with a light force. Of course, the operating slider 37 may be structured to be guided by a guide rail (not shown) separate from the support 36, but the support 36 also includes a guide rail function unless otherwise specified.

The operation slider 37 is preferably provided with a stopper mechanism for the support column 36, although not shown. With this, for example, the movement of the operation slider 37 is fixed at least at the rising end or the falling end or at an arbitrary position, and the main arm 1, the sunshade frames 5, 6, 7, 8, the sunshade sheet 21, etc. are agitated by the wind. This can prevent the product from being scratched and damaged.

The main arm 1 is supported by an elevating slider 47 whose base end moves up and down along the support column 36, specifically by a bracket 38 that is integrated with the operation slider 37, and is rotatably connected to the vicinity of the top of the support column 36. The middle part is suspended by an auxiliary arm 44. As a result, the main arm 1 whose base end is lifted along the support column 36 is changed to a horizontal position in which the distal end side protrudes forward while tilting forward along the rotation locus of the auxiliary arm 44. Specifically, in the case of this embodiment, the auxiliary arm 44 is rotatably connected by a bracket 45 at a position slightly closer to the base end than the middle of the main arm 1, for example. Therefore, when the base end of the main arm 1 moves upward as the operating slider 37 moves up and down along the support post 36, the auxiliary arm 44 moves the distal end of the main arm 1 away from the support post 36. The leading end of the main arm 1 is suspended so as to protrude horizontally from the support 36. In this embodiment, a bracket 45 is fixed to the main arm 1 by screws or welding, and the tip of the auxiliary arm 44 is rotatably attached to the bracket 45. On the other hand, the base end of the auxiliary arm 44 is rotatably connected to the vicinity of the top of the column 36 by a connecting pin 46. Here, the inclination of the sunshade 28 and the main arm 1 is not particularly limited, but they are slightly tilted backwards from the horizontal so as not to exceed the point of interest, but in some cases, the point of interest may be It may also be a mechanism in which the link mechanism is restrained by passing through and coming into contact with a stopper (not shown).

The main arm 1 may have any shape and structure as long as it has the strength to support the sunshade 28, but it goes without saying that it is preferably made of a material and shape that is as lightweight as possible and has excellent strength. Therefore, in this embodiment, an aluminum pipe material having a rectangular cross section is used, and the base end thereof is rotatably supported by a bracket 38 that interlocks with the operating slider 37.

As shown in FIG. 2, the column 36 is provided with a leg holder 48 at its lower end, and can be installed at any location by fixing the leg holder 48 to a foundation or the like with bolts or the like. However, the leg rests 48 are not necessarily attached, and the support columns 36 may be directly buried in the foundation and fixedly installed. In applications where the awning 28 is large or where strong winds are expected, it is preferable to dig a deep foundation and bury the pillars 36. Alternatively, a cylindrical block, such as a halved block, serving as a weight may be placed on the leg holder 48 and fixed by weight.

In the case of this embodiment, the main arm 1 is provided with a guide rail 2 on which the opening/closing slider 3 slides, as shown in FIG. As the guide rail 2, it is preferable to use a structural member, such as a channel material, which accommodates the opening/closing slider 3 so as to slide therein and hold it irremovably, such as a shaped material such as a shaped steel or an extruded or drawn material made of aluminum alloy. is used. For example, the guide rail 2 is made of an extruded material having a groove-shaped cross section as shown in FIG. Specifically, folded parts 22 that hold the rollers 23 of the opening/closing slider 3 are formed on both sides, and a groove shape is formed with an opening in the middle of the bottom, in which the main body 24 of the opening/closing slider 3 runs. An opening is formed to pass through in the longitudinal direction. The folded portion 22 is provided to support the roller 23 of the opening/closing slider 3 so that it can roll and not fall off. In this embodiment, the main arm 1 and the guide rail 2 are constructed as separate members, but the invention is not limited to this. In some cases, the main arm 1 and the guide rail 2 may be integrally molded ( In other words, the main arm 1 may also serve as the guide rail 2. Further, it is sufficient that the guide rail 2 is provided at least within the stroke range of the opening/closing slider 3, but in the case of this embodiment, the guide rail 2 is set to have approximately the same length as the main rail 1.

Here, the opening/closing slider 3 includes a rotatable link 4, and is connected to the outermost sunshade frame 5 via the link 4. In the case of this embodiment, for example, a U-shaped receiving metal fitting 25 is attached to the bottom side of the main body 24 of the opening/closing slider 3 by riveting or welding, and the link 4 is rotatably attached to both side walls of the U-shaped receiving metal fitting 25. For example, a U-shaped bracket 26 is welded to a bearing portion for the purpose. A cylindrical bearing portion at the base of the link 4 is inserted into the bracket 26 and rotatably attached with a fastener 27 to form a pair. In the case of this embodiment, the bracket 26, the main body 24 of the opening/closing slider 3, and the tires 23 are arranged symmetrically on almost a straight line, so that they are stably supported in a well-balanced manner laterally.

The opening/closing slider 3 may be of any structure, shape, or material as long as it moves along the main arm 1 and can be rotatably connected to the link 4 that drives the outermost sunshade frame 5. It is not limited to a specific structure. That is, the structure of the main body 24 of the opening/closing slider 3 is not particularly limited to its form or material as long as it can slide within the guide rail 2. For example, it may be made of a hat-shaped plate. Although it is possible to use a bent piece equipped with rollers 23 or a simple resin block with excellent sliding properties, in the case of this embodiment, a square pipe is used.

Further, the tip side of the link 4 rotatably connected to the opening/closing slider 3 is rotatably connected to the middle of the outermost sunshade frame 5 of the sunshade 28 . In the case of this embodiment, the bracket 20 is rotatably connected to the sunshade frame 5 by a substantially U-shaped bracket 20 and fasteners 29, which are fixed to the sunshade frame 5 by welding or riveting. Therefore, when the opening/closing slider 3 moves toward the tip of the main arm 1, it pushes and expands the outermost sunshade frame 5, and when it moves toward the base end of the main arm 1, it applies a force to fold it.

Further, the opening/closing slider 3 and the support column 36 are connected to each other by a rope 41 that changes direction at the tip end of the main arm 1. That is, one end of the rope 41 is fixed to the rope mooring fitting 40 of the support column 36, and the other end is connected to the opening/closing slider 3 inside the guide rail 2 via the pulleys 42, 43 of the main arm 1. Here, since the length of the rope 41, that is, the distance from the top of the pillar 36 via the pulleys 42 and 43 of the main arm 1 to the opening/closing slider 3, is constant, the opening/closing slider changes depending on the inclination of the main arm 1. The position of 3 is uniquely determined. In other words, the opening angle of the outermost sunshade frame 5 with respect to the inclination of the main arm 1 is uniquely determined.

(Sunshade opening/closing mechanism)
As shown in FIG. 3, the sunshade 28 according to this embodiment can be opened and closed at the tip of the main arm 1 so as to fan out in the left and right direction along the main arm 1. A plurality of movable sunshade frames 5, 6, 7, 8 and a fixed sunshade frame 9, which are supported so as to be openable and closable by a rotation center mechanism 35, and between these sunshade frames 5, 6, 7, 8 and the fixed sunshade frame 9. and a fixed sunshade frame 9, and a sunshade sheet 21 installed between the outermost sunshade frame 5 and the main arm 1. (to leave).

Specifically, in this embodiment, the movable sunshade frames 5, 6, 7, and 8 are independently rotatably supported by the rotation center mechanism 35 at the tip of the main arm 1, and the movement of the outermost sunshade frame 5 is The structure is such that the other sunshade frames 6, 7, 8 and the sunshade sheet 21 attached between them also follow the sunshade frames 6, 7, and 8 as they are pulled. That is, the sunshade frames 5, 6, 7, and 8 are interconnected through the sunshade sheet 21, and when the outermost sunshade frame 5 moves to spread around the rotation center mechanism 35, the sunshade sheet 21 becomes tense. The structure is such that the next sunshade frame 6 is pulled out, and the next sunshade sheet 21 is further tightened, so that the next sunshade frame 7 is further pulled out, and so on, so that the sunshade sheets 21 are successively expanded and fully opened. There is. Therefore, at the same time as the support of the link 4 to the outermost sunshade frame 5 is lost, all the sunshade frames 5, 6, 7, 8 and the sunshade sheet 21 therebetween are folded by gravity fall due to their own weight. In other words, when the main arm 1 and the auxiliary arm 44 are folded due to the lowering of the operation slider 37, the tension of the rope 41 applied to the opening/closing slider 3 is lost and all the sunshade frames 5, 6, 7, 8 rotate. The sunshade sheet 21 is also automatically folded. In addition, in the center of the sunshade frame that spreads in the left and right direction, a fixed sunshade frame 9 that is arranged and fixed along the main arm 1 is fixed non-rotatably to the base plate 10, and is attached to the sunshade frame 8. It is provided to fix the opposite side of the sunshade sheet 21. This fixed sunshade frame 9 also serves as the ends of the left and right sunshades 28.

The fabric of the sunshade sheet 21 is not particularly limited, and may be appropriately selected from commonly used sheet materials such as canvas, or from other new sheet materials. Although the shape of the sunshade sheet 21 is not required to be a specific shape, in the case of this embodiment, a substantially triangular sunshade sheet 21 is used.

In the case of the present embodiment, the rotation center mechanism 35 is configured such that the main rotation shaft 11, which is the main part of the sunshade sheet 21 that opens and closes in a fan shape, is disposed and supported between a pair of upper and lower substrates 10, as shown in FIG. 3, for example. It is set in. This rotation center mechanism 35 is provided at the tip of the main arm 1 by attaching the upper substrate 10 to the tip of the main arm 1 via a pair of L-beams 19 . The pair of upper and lower substrates 10 are connected to each other by bolting or welding with a substantially U-shaped spacer interposed therebetween.

For example, the sunshade 28 is constructed by rotatably connecting the base end sides of a plurality of sunshade frames 5, 6, 7, and 8 arranged radially around the rotation center mechanism 35 with one rotation center shaft 11. It is configured to be bundled and opened and closed in a fan shape around the central axis of rotation 11. The sunshade 28 of this embodiment has the rotation center axis 11 arranged in a direction perpendicular to the main arm 1, and opens and closes in a plane perpendicular to the rotation center axis 11 (that is, on a plane parallel to the main arm 1). possible.

(Sunshade rotation center mechanism)
Usually, in the case of the sunshade 28 for outdoor use, the sunshade frames 5, 6, 7, 8, and 9 that support the sunshade sheet 21 have a high cross-sectional shape to increase the moment of inertia of the area in order to increase the bending strength. There is a need to. For this reason, if you try to connect the base ends of the sunshade frames 5, 6, 7, and 8 with a single rotating shaft to open and close them in a fan shape, the key parts of the fan tend to rattle and become bulky and large. It comes with the problem of Therefore, it is conceivable to attach a thin plate-like connecting plate to the base end of each sunshade frame 5, 6, 7, and 8 to reduce the thickness of the part connected by the common rotation center axis 11. Unless the plate is made long, the sunshade frames 5, 6, 7, 8, and 9 will interfere with each other when approaching the mechanism at the center of rotation, and the fan angle cannot be made any narrower. In other words, the distance between the sunshade frames 5, 6, 7, 8, and 9 becomes wider toward the outside, which not only makes it difficult to create a compact folding structure, but also creates a storage situation that is susceptible to the effects of wind. be.

On the other hand, separate rotation centers are set for each of the sunshade frames 5, 6, 7, 8, and the sunshade frames 5, 6, 7, 8 are arranged parallel to each other when closed. 8 can be stored without overlapping, a compact folding structure can be expected. However, since the rotation centers of each sunshade frame 5, 6, 7, and 8 are different, when the sunshade 28 is opened and closed, the sunshade sheet The distance to the mounting point where 21 is fixed to each sunshade frame 5, 6, 7, 8, 9 changes for each sunshade frame 5, 6, 7, 8, 9, so close the sunshade 28. There is a problem in that the sunshade sheet 21 is forcibly stretched out while the user is in the room.

Therefore, the rotation center mechanism 35 of this embodiment has a common rotation center axis 11, connection plates 31, 32, 33, 34 with different bending angles for each awning frame 5, 6, 7, 8, 9, and individual rotation Guide shafts 13, 14, and 15 are provided. That is, each sunshade frame 5, 6, 7, 8 has a common rotation center axis 11 and individual rotation guide shafts 13, 14, 15 for each sunshade frame 5, 6, 7, 8, as shown in FIG. The individual rotary guide shafts 13, 14, 15 are provided so that their swing ranges are restricted by moving within their respective arcuate guide holes 16, 17, 18. In other words, each sunshade frame 6, 7, 8 moves the individual rotation guide shafts 13, 14, 15 within a certain range along the arc-shaped long holes 16, 17, 18 of the plate, with the common rotation center axis 11 as the pivot. It has a structure that opens and closes in a fan shape by opening and closing it in a fan-like manner (see Fig. 8). In the case of this embodiment, four sunshade frames 5, 6, 7, and 8 are provided on each side, and the total of eight sunshade frames 5, 6, 7, and 8 extend to an angle of, for example, 180°. It is set up like this. Note that the central sunshade frame 9 is connected and fixed to the board 10 with two bolts. One end of the sunshade sheet 21 at the innermost end is fixed. On the other hand, since the sunshade frame 5 is connected and interlocked with the opening/closing slider 3 via the link 4, a guide for regulating the swing range is not required, and a guide hole for guiding the rotation guide shaft 12 is not provided. Not yet.

As shown in FIG. 8, the four movable sunshade frames 5, 6, 7, and 8 are installed in parallel at regular intervals when the sunshade 28 is closed, and spread radially at equal angles when expanded. It is supported by connecting plates 31, 32, 33, and 34. The outermost sunshade frame 5 is displaced, for example, by a connecting plate 31 bent at 90° so as to be farthest from the rotation center axis 11 and to form a substantially right angle to the main arm 1 in the unfolded state. The second awning frame 6 from the outside is the second away from the rotation center axis 11 by the connecting plate 32 bent at about 100 degrees, and is tilted at about 67.5 degrees in the unfolded state. The third sunshade frame 7 from the outside is displaced third away from the rotation center axis 11 by a connecting plate 33 bent at about 150 degrees, and tilted at about 45 degrees in the unfolded state. The fourth awning frame 8 from the outside is displaced, for example, by a straight connecting plate 34 so that it is the fourth away from the rotation center axis and is approximately 22.5 degrees from the main arm 1 in the unfolded state.

As a result, when the sunshade 28 is closed, the sunshade frames 5, 6, 7, and 8 are arranged parallel to each other, as shown in FIG. At this time, the positions of the base ends of the sunshade frames 5, 6, 7, and 8 are arranged in four rows at equal intervals under the common rotation center axis 11 as shown in FIG. 8, but the positions of the individual rotation guide shafts are are at different radial positions and different angles from the common rotation center axis 11. As a result, the four connecting plates 31, 32, 33, 34 are fitted to the common rotation center axis 11 at regular intervals, while the base ends of the sunshade frames 5, 6, 7, 8 are at the same height. arranged in the same position.

In this embodiment, connection plates 31, 32, 33, 34 having different bending angles (different offset amounts) are fixed to the base end side of each sunshade frame 5, 6, 7, 8 by screws, for example. By fitting the connecting plates 31, 32, 33, and 34 to the common rotation center axis 11 while being shifted in the axial direction, the sunshade frames 5, 6, 7, and 8 are arranged at the same height. (See Figure 8). Further, in the closed position, each sunshade frame 5, 6, 7, 8 is supported by connection plates 31, 32, 33, 34 so as to be arranged parallel to each other. Therefore, the sunshade 28 of this embodiment can be compactly stored with the plurality of sunshade frames 5, 6, 7, 8, and 9 bundled in parallel to each other. Moreover, the positions where the sunshade sheet 21 is fixed to the sunshade frames 5, 6, 7, 8, and 9 are closer to each other when closed than when unfolded, so when the sunshade 28 is stored, the fabric loosens and unnecessary tension is applied. Never.

The connecting plates 31, 32, 33, and 34 are arranged on the rotation center axis 11 so as to be appropriately shifted in the axial direction so as not to interfere with each other, and are rotatably fastened with appropriate spacers interposed therebetween. That is, the sunshade frames 5, 6, 7, and 8 are provided at the same height but at different heights at the rotation center axis 11. In the case of this embodiment, the outermost and third sunshade frames 5 and 7 from the outside are sandwiched between two connecting plates from both the top and the bottom due to strength issues, although this is not a particular mechanical requirement. The second and fourth (innermost) sunshade frames 6 and 8 from the outside are supported by one connecting plate. Incidentally, the individual rotation guide shafts 12, 13, 14, and 15 are also rotatably fastened with appropriate spacers interposed therebetween.

The connecting plates 31, 32, 33, 34 and the sunshade frames 5, 6, 7, 8 may each be provided with a reinforcing rib plate, such as a triangular plate, at the base end, although not shown.

According to the self-supporting sunshade having the structure shown in FIGS. 1 to 8 configured as described above, in order to open the sunshade 28, it is sufficient to lift the operation slider 37 along the support column 36. As the operation slider 37 rises, the base end portion of the main arm 1 connected to the bracket 38 rises along the support column 36. The tip (rotation center mechanism 35) side of the main arm 1 falls in the direction away from the support column 36, that is, in the forward direction, in combination with the movement of the base end and the auxiliary arm 44. In synchronization with this movement, the opening/closing slider 3 is pulled relatively along the main arm 1 toward the tip of the main arm 1 by the rope 41, and the base end of the link 4 is pulled toward the tip of the main arm 1, that is, the rotation center mechanism 35. pull up towards. As a result, the outermost sunshade frame 5 connected to the link 4 is pushed out to widen its angle with respect to the main arm 1 around the rotation center mechanism 35, and the sunshade sheet 21 attached to the sunshade frame 5 → the sunshade. The sunshade 28 is opened in a fan shape by being pulled out in the order of frame 6 → sunshade sheet 21 → sunshade frame 7 → sunshade sheet 21 → sunshade frame 8 → sunshade sheet 21. In other words, while tilting the main arm 1 forward and lifting it to a nearly horizontal position, the opening/closing slider 3 is moved forward of the main arm 1 and pushes the outermost sunshade frame 5 via the link 4. Expand it to open the awning 28. In other words, in the self-supporting sunshade of this embodiment, at the same time as the operation slider 37 is lifted, the sunshade 28 is opened and closed in a fan shape in the left and right directions, and protrudes forward to take a substantially horizontal position.

Furthermore, when the free-standing sunshade is to be closed, the operator simply presses down the operating slider 37. That is, as the operating slider 37 is pushed down, the base end of the main arm 1 is pulled down along the support post 36, so the main arm 1 is pulled along the support support 36 as a whole while raising its distal end side. and changes to an upright position. At this time, the distance between the pillar 36 and the pulley 42 of the main arm 1 narrows, and at the same time the rope 41 loosens and the link 4 is closed by the weight of the awning frame 5 (direction along the vertical line). , the opening/closing slider 3 is pushed down toward the base end of the main arm 1. The sunshade 28 loses the support of the link 4 and is automatically folded under its own weight. That is, while closing the sunshade 28, the main arm 1 is raised and lowered while being pulled back toward the front (post 36).

In this way, the free-standing sunshade of this embodiment allows the sunshade 28 to be opened and closed with one touch. Note that even if the lifting slider 47 does not have a locking mechanism, the closed state is maintained by the weight of the main arm 1 and the sunshade 28, and the open state is maintained by the weight of the sunshade 28 including the main arm 1.

According to the above-described embodiment, it is possible to provide a unique and innovative movement of the sunshade, in which the sunshade 28 is raised and simultaneously opened and closed in a fan-like manner in the left and right directions, and jumped forward to a substantially horizontal position. Moreover, this interesting movement can be achieved with just one action. Here, there are no particular limitations on the shape or design of the sunshade 28, but if the shape or design is reminiscent of the wings of a butterfly or bird, for example, it will look like a butterfly or bird flying up while flapping its wings. Because it is reminiscent of traditional awning movements, it can perform interesting and novel movements that have not been seen before in awnings, and can impress those who see it. For example, by using the shape and design of an animal such as a bear with its arms outstretched, it can evoke a fearful action like a bear with its arms outstretched and pouncing on you. Furthermore, since it creates a unique and innovative movement that has never been seen before, it can be used not only as a sunshade but also as an object.

Moreover, since the sunshade 28 is opened by utilizing the force of the main arm 1 to fall, and closed by the own weight of the expanded sunshade 28 itself, the operation slider 37 is simply moved up and down along the support column 36. It can be opened and closed easily with a light operating force.

Note that although the above-described embodiment is an example of a preferred embodiment of the present invention, the present invention is not limited thereto, and various modifications can be made without departing from the gist of the present invention.

For example, in the above-described embodiment, the explanation was mainly given of an example of configuring the sunshade 28 with a bilaterally symmetrical shape, but the invention is not particularly limited to this, and it is also possible to configure the sunshade 28 with a bilaterally asymmetrical shape. . For example, as shown in FIG. 5, by making the lengths of the left and right sunshade frames 5, 6, 7, and 8 and the length of the sunshade sheet 21 different around the main arm 1, an asymmetric sunshade 28 can be constructed. Furthermore, as shown in FIG. 4, two main arms 1 may be arranged at 180-degree intervals with respect to one support 36, and each main arm 1 may be provided with a symmetrical or asymmetrical sunshade 28. By equipping it, a sunshade 28 in an expanded state as shown in FIG. 5 may be configured. Further, in the above-described embodiment, an example is given in which the sunshade 28 is formed in a rectangular shape reminiscent of the wings of a butterfly or a bird, but the sunshade 28 is not particularly limited to this, and is semicircular or semicircular. The above configuration may be configured as a fan-shaped sunshade having an angle of less than 360°.

Furthermore, in the above-described embodiment, the operating mechanism is used to simultaneously open and close the left and right awnings 28 by raising and lowering one operating slider 37; By providing an operating mechanism, the awning 28 may be opened and closed independently for each compartment. For example, the opening/closing action of the sunshade 28 may be modified by providing two systems of opening/closing sliders and ropes and staggering the opening/closing timing of the left and right sunshades 28.

Furthermore, although the sunshade 28 according to the above-described embodiment is provided so that the sunshade sheet 21 is tightened when the sunshade frame is unfolded, the sunshade sheet 21 is not particularly limited to this. It may be expanded. For example, although not shown, by directly connecting adjacent sunshade frames 5, 6, 7, 8, and 9 with a tape-like connecting member shorter than the width of the sunshade sheet 21, the sunshade sheet 21 can be tightened. As a structure in which the next sunshade frame 6 is pulled out, the adjacent sunshade frames 5, 6, 7, 8, and 9 may be pulled and unfolded by a tape-like connecting member (not shown). In this case, the distance between the adjacent awning frames 5, 6, 7, 8, 9 and the awning frames 5, 6, 7, 8, 9 is such that the tape-like connecting member is tightened before the awning sheet 21 is tightened. Since the sunshade sheets 21 are kept at constant intervals, the sunshade sheet 21 can form drooping folds between the adjacent sunshade frames 5, 6, 7, 8, and 9.

Further, in the above-described embodiment, the connection plates at the proximal ends of the sunshade frames 5, 6, 7, 8, and 9 are fitted to one common rotational center shaft 11 while being shifted in the axial direction, and are connected to each other. By making the bending angles of the connecting plates of the sunshade frames 5, 6, 7, 8, and 9 different for each one, the plurality of sunshade frames 5, 6, 7, 8, and 9 are parallel to each other when the sunshade 28 is closed. Although the sunshade frames 5, 6, 7, and 8 are arranged side by side so as not to interfere with each other, they are not particularly limited to this. 7 and 8 so as not to interfere with each other, or the installation position of the book with respect to the common rotation center axis 11 between multiple sunshade frames can be set at different heights for each frame. good. Even in this case, the sunshade frames 5, 6, 7, 8, and 9 can be prevented from interfering with each other near the common rotation center axis 11 of the sunshade 28, so that the sunshade 28 can be stored compactly. Of course, even if the sunshade frames 5, 6, 7, 8, and 9 interfere in the vicinity of the common rotation center axis 11, the closing angle of the sunshade 28 will not be the minimum, and this is allowed. This does not pose any particular problem under the usage environment.
