Description

  The present invention relates to a corner awning device that is used for covering corner portions of various buildings, frame structures, and the like with good appearance.

  Conventionally, a movable awning device usually winds a canvas that is unfolded forward from a wall-side portion around a canvas take-up shaft supported by a bearing on an outer wall portion of a building by a manual handle or an electric motor. A canvas take-up device that takes up or rewinds and a canvas tensioning device that connects a front bar that fixes the front end of the canvas with a foldable swing arm or the like (for example, the following) Non-Patent Documents 1 and 2 (hereinafter referred to as the former), many of which are installed as sunshades and rain shields around the terrace and outside the store, or as part of buildings and store decorations. Aging is planned.

  Therefore, in laying out the former awning device around the outside of the building, the plane form of the corner portion of the building is the orthogonal form shown in FIG. 15A, the chamfered form shown in (B), (C In the case of exhibiting the obtuse angle shape shown in FIG. 5) or the acute angle shape shown in (D), on the outer peripheral portion of the range perpendicular to any of the front wall W1, the side wall W2 and the oblique wall W3 of the building, Various long and short rectangular canvases P (hereinafter referred to as rectangular canvases) are developed and covered.

On the other hand, in order to cover the corner space part of a building, conventionally, a movable awning device having a configuration shown in the following (a) to (d) has been proposed (for example, see Patent Document 1 below, hereinafter the latter). Called).
(A) An awning support frame that incorporates the entire apparatus is supported obliquely forward and supported by a fixed bracket at the corner end, and the long side of the substantially right triangle-shaped canvas is wound up by an electric motor, or the winding roller is rewound. The two bodies are supported by bearings at both front and rear ends of the awning support frame.
(B) The base end of the folding arm biased in the expanding direction is attached near the middle of the base pipe, and the top of the triangular canvas is attached to the arm holder at the tip.
(C) A decorative panel is pivotally provided at the front end of the awning support frame so that the decorative panel can be expanded, and the arm holder is slidably supported along the groove at the rear of the decorative panel.
(D) The tip of the awning support frame is lifted and supported by a wire rope, and is pulled up to the rear upper part of the corner end by a hoist to store the entire apparatus in an inverted state.
“Awning Sales Manual”, Japan Awning Association, January 2004, p.9-11 "Technical Manual" (French awning) [online], Miyahan Co., Ltd., "Search June 28, 2002 and June 9, 2004", Internet <URL: http://www.miyahan.co.jp/ tecnicalm / index.html> Japanese Utility Model Publication No. 4-40336

However, in the former awning device, the corner space that is outside the above range and left on the outer periphery of the building, for example, the rectangular space Z1 shown in FIG. 15A, (B), or (C) The acute-angled space part Z2 shown and the obtuse-angled space part Z3 shown in (D) cannot be covered with good appearance.
Therefore, if one canvas take-up shaft is attached to the corner position of the front wall W1, the other canvas take-up shaft is turned up and down, and the corners of the other side wall W2 and the slant wall W3 are placed. As a result, the corner spaces Z1 to Z3 shown in FIGS. 15A to 15C can be covered.

However, such a small-handed technique impairs the decorativeness and appearance of the corner space on the outer periphery of the building.
In particular, corners in various buildings often face two-way pedestrian roads, or face intersections, and are in contact with the eyes of an unspecified number of people. It is also a place that has favorable business conditions such as excellent advertising effects.
In that the awning device incorporated in such a conspicuous place has to be made into a device only in a state where the corner space portions Z1 to Z3 are missing, or that it can only be dealt with by the technique of a small hand as described above, It lacks technical interest and usefulness as a movable awning device.

  On the other hand, in the latter awning device, the triangular canvas developed in the corner space portion is cantilevered at the corner end portion of the protruding corner portion, so the load of the entire device is concentrated on the fixed bracket protruding from the corner end portion. . In addition, since the awning support frame is lifted by the wire rope, it is easy to cause left-right swinging of the entire apparatus when the canvas is unfolded, and is particularly unstable and easily affected by wind. In addition, the entire device is lifted by a wire rope, pulled up to the corner end, and stored vertically upside down, so there is a concern that overhead drop may occur when considering the situation of wire rope deterioration and cutting. In addition, the inverted storage exposes the back side of the entire apparatus to the front surface of the corner end, which impairs the appearance during storage.

  Therefore, the present invention provides a corner awning apparatus incorporating the contents of the invention that can cope with various technical problems assumed in providing a new product as well as the above technical problems.

  As corner awning devices S1 to S6 of the present invention, as described in claim 1, canvas take-up shafts J1 to J13 for winding or rewinding corner canvas G1 to G4 are used as inner shafts 12, 12A and 12B. The outer canvas 13 is supported so as to be movable in the axial direction of the inner shafts 12, 12A, 12B. When the corner canvas G1-G4 is wound up or rewound, the hems of the corner canvas G1-G4 are formed. The front bars 36 and 36A for supporting the parts are configured to be pushed in parallel diagonally forward or pulled backward diagonally by foldable swinging arms 44 and 45, N1, N2, T1, T2, V1, and V2. It is characterized by that.

  In other words, as described in claim 2, the corner canvas G1 to G4, the inner shafts 12, 12A, 12B, and the outer roller 13 supported so as to be movable in the axial direction of the inner shafts 12, 12A, 12B. When winding or rewinding the canvas take-up shafts J1 to J13 and the corner canvas G1 to G4, the front bars 36 and 36A that support the skirts of the corner canvas G1 to G4 are provided. Provided are corner awning devices S1 to S6 including swing arms 44, 45, N1, N2, T1, T2, V1, and V2 that are pushed diagonally forward in parallel or pulled backward and folded.

  Thereby, the corner part including the corner space part of the circumference of various buildings can be covered with appearance, and conversely, at the time of storage, it is possible to cope with compact storage in the wall part at the corner position. As a result, it will dramatically improve the decoration and appearance of the corners of buildings, and provide innovative and innovative products to the industry that are rich in technical interest and usefulness as corner awning equipment. be able to.

At that time, the outer windings J1 to J13 for winding or rewinding the corner canvas G1 to G4 are supported so as to be movable in the axial direction of the inner shafts 12, 12A, 12B and the inner shafts 12, 12A, 12B. And a roller 13.

About the first example of canvas tension device

Next, the canvas tension device K1 of the first example will be described.
Reference numerals 44 and 45 denote a pair of parallel swing arms, which are urged and supported so as to be able to push the front bar 36 in parallel toward an obliquely forward corner space, and the arm base end is pivotally supported. The brackets 46 and 47 to be fixed to the outer wall W1 to W3 at the bottom of the casing 11 near the corner of the building at the tip of the canvas take-up shaft J1 It fixes to the support bar (not shown) passed in the direction.
Reference numerals 48 and 49 denote brackets that pivotally support the front ends of the swing arms 44 and 45, respectively, in the vicinity of the middle portion of the front bar 36 and at the back position of the rear end portion with the same interval as the brackets 46 and 47. It is fixed.
Then, a spring (not shown) having appropriate spring elasticity is incorporated in one or both of the proximal end portion and the distal end portion of the swing arms 44 and 45, and swings by the elastic biasing force. A pair of arms 44 and 45 rotate in parallel in the expanding direction, and push the front bar 36 in parallel toward the corner space portion diagonally forward.
On the contrary, when the corner canvas G1 is wound up, the pair of swing arms 44 and 45 are driven to rotate against the elastic urging force so that the front bar 36 is directed toward the diagonally rear wall. Pull in while moving in parallel.

The swing arms 44 and 45 are mounted in parallel with a suitable interval so that the two bodies rotate in the same direction synchronously. When the arm length is shorter than the arm length, it is desirable to refract the positions near the arm base end portions as in the swing arms 44 and 45 shown in FIGS.
The refracting portions 441 and 451 enable a compact housing at the edge of the wall with respect to the swing arms 44 and 45.

Action of corner awning equipment

First, in order to wind the corner canvas G1 around the canvas winding shaft J1, an operating handle (not shown) is engaged with the hook 23 and is manually rotated.
Then, the inner rotary shaft 12 and the outer roller 13 are integrally rotated through the meshing of the gears 20 and 21, and the top surface 1 of the canvas fixed to the out roller 13 is set to the inner side, and the back surface is set to the outer side. Wrap. That is, as shown in FIGS. 10B and 10C and FIGS. 11B and 11C, the corner canvas G1 is wound downward.
On the other hand, the swing arms 44 and 45 are driven to rotate rearward against the elastic urging force and translate the front bar 36 obliquely rearward.
At the same time, the tension of the canvas tensioning device K1 acts on the outer roller 13 via the canvas G1, and the tensile force by the connecting wires 34 and 35 acts on the outer roller 13, and these actions are rearward with respect to the outer roller 13. It is converted into sliding force.
As a result, the outer roller 13 moves backward in the axial direction of the inner rotary shaft 12.
Then, as shown in FIGS. 10A to 10C and FIGS. 11A to 11C, the canvas main body R1 is gradually wound around the outer roller 13, and the canvas overhang R2 is 13 is wound around the outer peripheral portion of the inner rotary shaft 12 exposed in accordance with the backward movement.
Accordingly, as shown in FIGS. 10D and 11D, the corner canvas G1 is wound without substantially protruding from the axial length of the canvas winding shaft J1, and the swing arms 44 and 45 are also wound. Is folded in a lying state at the edge of the wall, overlapped with the front bar 36, and stored compactly.

In the above case, the connecting wires 34 and 35 cross-connect the front bar 36 and the outer roller 13, and a tensile force acts to slide the outer roller 13 backward in response to the diagonal movement of the front bar 36.
Therefore, when the corner canvas G1 is wound, the canvas main body R1 is prevented from being distorted or in-plane deformation is prevented, and the corner canvas G1 can be smoothly and regularly wound.
In this respect, when the connecting wires 34 and 35 are not cross-connected, the canvas main body R1 is easily distorted or in-plane deformation is easily caused by the influence of the degree of hardness, elasticity, knitting density, etc. of the canvas fabric. Become.
As a result, adverse effects such as irregular winding of the corner canvas G1 and impaired smooth backward movement with respect to the outer roller 13 are assumed.

Next, contrary to the above, when the corner canvas G1 wound around the canvas winding shaft J1 is expanded toward the corner space on the outer periphery of the building, the operation handle is rotated in the opposite direction. Manipulate.
Then, the elastic urging forces of the two oscillating arms 44 and 45 folded in the wall portion are released, and the oscillating arms 44 and 45 are urged and rotated in the expanding direction by the pressing urging force, and the front bar 36 is rotated. Is moved in parallel toward the corner space part ahead of the angle and pushed out.
At the same time, the inner rotating shaft 12 and the outer roller 13 integrally rotate in the reverse direction so that the corner canvas G1 wound around the canvas winding shaft J1 is rewound and the swinging arm acts on the front bar 36. A sliding force in the forward direction with respect to the outer roller 13 acts by the elastic biasing force of 44, 45, the tension of the canvas G1, and the tensile force of the connecting wires 34, 35 to be rewound. While moving forward along the rotary shaft 12, the motor rotates backward.

In this manner, the front bar 36 is pushed obliquely forward by the elastic urging force of the swing arms 44 and 45, the integral reverse rotation of the inner rotary shaft 12 and the outer roller 13, and the forward movement of the outer roller 13, The corner canvas G1 is smoothly pushed out into the corner space portion diagonally forward.
Accordingly, as shown in FIGS. 1 and 2, the two corner awning devices S1 are attached so as to abut on the corner position of the front wall W1 and the corner position of the side wall W2, and are attached to the respective canvas winding shafts J1. The wound corner canvas G1 is rewound.
As a result, the two corner canvases G1 are pulled out obliquely forward and developed in a face-to-face state, so that the outer periphery of the building including the corner space portions Z1 to Z3 is covered with good appearance.

  In the above case, the inner rotary shaft 12 is manually rotated. However, the rotary shaft 22 shown in FIGS. 5, 8, and 9B is rotated forward and backward by an electric motor (not shown). Alternatively, a spur gear can be attached instead of the worm gear 20, the drive gear can be meshed with the spur gear, and the drive gear can be rotated forward and backward by an electric motor (not shown).

Combination with conventional awning equipment

By the way, as shown in FIGS. 12 to 14, an awning device Q having a conventional structure that unfolds and winds up a rectangular canvas P is combined with the latter half of the awning device S 1 according to the present invention.
In the figure, reference numeral 51 denotes a canvas take-up shaft built in a casing 52, to which a base end portion of a rectangular canvas P is attached, and the canvas outlet is opened at an upper position of the casing 52. 53 is a front bar for fixing the front end of the canvas P, and L1 and L2 are a pair of two fold swing arms, which are elastically attached in a direction to spread the two swing arms L1 and L2 by a spring or a wire. It is fast.
The awning device Q having a conventional structure is attached so that the portion near the tip of the casing 52 is substantially overlapped with the position of the bottom half of the casing 11 of the awning device S1 according to the present invention. The ends are fixed to the outer walls W1 to W3 and others with a left and right interval.
Therefore, when the canvas take-up shaft 51 is taken up and rotated by a manual handle or an electric motor, the take-up shaft 51 is wound up with the back side of the rectangular canvas P on the inner side and the front side on the outer side. The two folding swing arms L1 and L2 are folded against the elastic urging force, folded inward, and stored by moving the front bar 53 in parallel toward the wall.
In this way, by arranging the corner awning device S1 of the present invention and the awning device Q having the conventional structure in combination, the outer circumference including the corner space portion of various buildings can be unified like a single unit. Covered with good appearance.

  In the above case, the corner canvas G1 is wound down and the rectangular canvas P is wound up so that the step at the boundary between the canvases G1 and P at the time of unfolding is not noticeable. Conversely, the overlapping state of the casing 52 of the awning device Q and the casing 11 of the awning device S1 of the present invention is changed up and down, and the corner canvas G1 is wound up and the rectangular canvas P is wound down. You can also.

About the second example of canvas take-up shaft

Next, the configuration of the canvas take-up shaft J2 of the second example for electrically driving the inner rotary shaft 12 will be described with reference to FIGS. 17 (A) and 17 (B).
In the figure, reference numeral 54 denotes a cylindrical electric motor inserted through the rear portion of the inner rotary shaft 12, and a motor output shaft 541 is provided at the front end portion thereof, and a fixing shaft portion 542 is provided at the rear end portion thereof. is doing. Reference numeral 55 denotes a bearing socket having a concavo-convex surface to be inserted into the inner rotary shaft 12, and the motor output shaft 541 is fitted into the shaft hole 551.
Reference numeral 19C denotes an end cap that is fitted into the rear end portion of the inner rotary shaft 12, and supports the position of the rear portion of the main body of the electric motor 54 in a circular hole 194 of the cap main body portion.
Therefore, after the bearing socket 55 is fitted and fixed to the motor output shaft 541, the electric motor 54 is inserted into the rear position of the inner rotary shaft 12, and the end cap 19C is inserted into the rear position of the main body of the electric motor 54. Then, the cap 19C is fitted into the rear end portion of the inner rotary shaft 12, and the shaft portion 542 of the electric motor 54 is fitted and fixed to the bearing portion 161 of the end cap 16. As a result, the electric motor 54 is incorporated into the inner rotary shaft 12.
Accordingly, when the electric motor 54 is driven, the output shaft 541, the bearing socket 55, and the inner rotary shaft 12 integrally rotate forward and backward, thereby automating and saving labor for winding the corner canvas G1.
In the above case, the electric device is incorporated in the rear part of the inner rotary shaft 12, but can also be incorporated in a position near the tip of the rotary shaft 12.

Interlocking device of awning device

In the above case, the two corner awning devices S1 face each other at the corner position of the building and the respective canvas take-up shafts J1 and J2 are manually rotated or electrically rotated. Will be dealt with by incorporating a manual device as shown in FIGS.
In the figure, reference numeral 57 denotes a corner cap bent at a right angle. The inside of the corner cap is partitioned by a bearing portion 571, and a casing 11 having a canvas take-up shaft J1 is fitted to one and the other of the corner cap 57. At the same time, the support shaft 181 of the inner rotary shaft 12 butted orthogonally is supported by the bearing portion 571.
At the rear rear position of the bearing portion 571, the rotating shaft 22 provided with the hook 23 is vertically supported by bearings, and the worm 21 fitted in the upper position of the rotating shaft 22 and the support of one and the other inner rotating shaft 12 are supported. The worm gears 20 fitted to the shaft 181 are engaged with each other.
As a result, the two canvas take-up shafts J1 facing the front wall W1 and the side wall W2 rotate forward and backward in conjunction with each other, and the respective corner canvas G1 is taken up and rewound in conjunction with each other.

18 (A) and 18 (B) show the case where two canvas take-up shafts J1 are abutted orthogonally to the corner position of the building, the bending angle of the corner cap 57 is an obtuse angle. If it is formed into a shape of a shape or an acute-angled cap, the corner portion of the building can correspond to any of the obtuse and acute-angle shapes shown in FIGS. 16 (C) and 16 (D).
Further, the interlocking rotating shaft 22 can be rotated forward and backward by an electric motor (not shown).
Of course, when the electric device as shown in FIGS. 17 (A) and 17 (B) is used as the canvas take-up shaft J2 built in the inner rotary shaft 12, it is attached to the corner position by electrically synchronizing it. Since the two corner awning devices S1 can be interlocked, there is no need to incorporate a manual or electric interlocking device as shown in FIGS.

About the corner canvas deformation example

By the way, in the case of the canvas tension device K1 described above, when considering the smoothness of the operation when winding the corner canvas G1, the smoothness when the outer roller 13 is moved backward, and the like, The expansion angle is practically limited to a maximum of about 75 to 80 degrees.
Therefore, the protruding length of the corner canvas G1 obliquely forward is limited by the expansion angle of the swing arms 44 and 45. As a result, the length of the corner canvas G1 is about 20 cm between the one and the other canvas that are deployed facing each other. A gap is formed.
Therefore, in order to narrow the gap between the opposite sides of the canvas oblique sides as much as possible without changing the expansion angle of the swing arms 44 and 45, the three types of corner canvases G2 to G4 as shown in FIGS. I will provide a.
Among them, in the case of the canvas G2 of FIG. (A), a canvas hypotenuse 5 parallel to the canvas hypotenuse 3 of the canvas G1 of the first example shown by an imaginary line is formed on the basis of the foremost position of the outer roller 13, and the other The canvas base 6 is vertically raised from the tip of the canvas skirt 2, and a connecting through hole 7 is formed in an obtuse angled mountain where both sides 5, 6 intersect.
At the same time, crossed through holes 32 and 33 are formed in an X shape in the enlarged canvas main body R1, and the vertically extending trapezoidal canvas overhang R3 is formed by vertically cutting off the tip of the canvas skirt 2. Is formed.
In the case of the canvas G3 in FIG. (B), the canvas hypotenuse 5 is formed in the same manner as described above, the canvas hypotenuse 8 is formed obliquely upward from the tip of the canvas hem side 2, and the angle formed by both sides 5,8 is formed. Are formed at a substantially right angle, and a connecting through hole 7 is drilled at a right-angle crest where both sides intersect.

Accordingly, in the case of the canvases G2 and G3 shown in FIGS. 19A and 19B, the leading end of the canvas top 1A fixed to the outer roller 13 and the leading end of the canvas skirt 2 fixed to the front bar 36 are used. The portion that protrudes outward from the line connecting the two hangs down when the canvas is unfolded or the canvas is wound up unless otherwise restricted.
Therefore, as shown in FIGS. 18A and 18B, two canvas take-up shafts J1 attached to the corner portions of the front wall W1 and the side wall W2 are configured so as to be interlocked with each other. The through-holes 7 of the canvas overhanging portion R3 of the body canvas G2, G3 are connected to each other by an extensible tool 10 such as a rubber string or a coil spring.
Accordingly, as shown in FIGS. 20 (A), (AA), (B), and (BB), the protruding portions described above are pulled together by the extender 10, and the swing arms 44 and 45 are elastically attached. By the force, the canvas main body R1 and the canvas overhanging portion R3 are kept in a tensioned state, and the winding and rewinding to the respective canvas winding shafts J1 are performed in conjunction with each other.
As a result, it is possible to further narrow the gap between the opposite canvas hypotenuses 5 as compared with the corner canvas G1.

Further, in the case of the canvas G4 of FIG. 19C, unlike the cases of FIGS. A and B, the length of the front bar 36 is relatively shortened, and the canvas hem fixed to the front bar 36 is used. A hypotenuse that connects the tip of the side 2A and the tip of the canvas top side 1A fixed to the outer roller 13 is formed on the canvas fold line 9.
In addition, an angle formed by the canvas oblique side 5A having an inclination angle of about 50 degrees toward the tip of the canvas top side 1A and the canvas oblique side 8A obliquely upward from the tip of the canvas bottom 2A is formed at a substantially right angle. The right-angled mountain parts to be connected are connected by the expansion and contraction tool 10.
Then, when the corner canvas G4 is rewound, the corner canvas G4 is unfolded gradually from the canvas fold line 9.
On the other hand, when winding the canvas overhanging portion R3 around the inner rotary shaft 12 of the canvas winding shaft J1, the base end portion that is folded in the mountain is pulled up so that it is flush with the canvas main body portion R1. It is wound up with tension.
As a result, as shown in FIGS. 20 (C) and 20 (CC), the mountain is bent at a steep slope from the canvas mountain fold line 9 and supported by tension, and the gap width between the opposite canvas hypotenuses 5A is reduced and expanded. Improve the appearance of the corner space at the time.

About the third example of canvas winding shaft

Next, the canvas winding shaft J3 of the third example shown in FIGS. 21A and 21B will be described.
The canvas take-up shaft J3 is different from the canvas take-up shafts J1 and J2 in the first example and the second example in that the casing 11 for taking up and storing the canvases G1 to G4 is an essential component. The end portion of the inner rotary shaft 12A whose length is about 1/2 to 2/3 of the casing 11 is cantilevered and supported by the end cap 15, and the outer roller 13 is slidably inserted and supported on the inner rotary shaft 12A. is doing.
58 is a slide bearing fixed to the rear end portion of the outer roller 13, and the slide bearing 58 is guided by the inner wall surface of the casing 11 and slides in the front-rear direction.
Therefore, when winding up the canvases G1 to G4, the inner rotary shaft 12A and the outer roller 13 are integrally rotated, and the swing arms 44 and 45 are rotated backward in an arc shape against the elastic biasing force. The outer roller 13 is wound up while being moved backward to the rear of the casing 11 by the tension of the canvases G1 to G4 and the tensile force of the connecting wires 34 and 35.
Conversely, when the canvases G1 to G4 are deployed, the front bar 36 is pushed forward obliquely by the elastic biasing force of the swing arms 44 and 45, and the outer roller 13 that rotates reversely integrally with the inner rotary shaft 12A. Then, it moves forward toward the tip of the casing 11, and the canvases G1 to G4 wound around the canvas winding shaft J3 are pulled out.

A close-up prevention device for canvas overhangs

  The canvas take-up shafts J4 and J5 of the following fourth and fifth examples and canvas take-up shafts J11 to J13, which will be described later, are projected onto the inner rotary shafts 12 and 12A exposed by the backward movement of the outer roller 13. The present invention relates to a configuration for preventing tight winding when winding the portions R2 and R3 and ensuring a smooth backward movement of the outer roller 13.

About the 4th example of canvas take-up shaft

First, the canvas take-up shaft J4 of the fourth example shown in FIGS. 22 to 24 will be described.
Reference numeral 50 denotes a synthetic resin slide rope having moderate elasticity and elasticity, and about four of them are incorporated in the axial direction of the inner rotary shaft 12.
Reference numerals 18A and 19A denote end caps that are fitted to both front and rear ends of the inner rotary shaft 12, and each of the slide ropes 50 is rotated in a U-shape at four outer peripheral positions from the cap main body portion to the lid portion. Rope passages 182 and 192 that are bent and turned outward are formed.
Reference numerals 24A and 25A denote end caps fitted to both front and rear ends of the outer roller 13, and a rope insertion hole 263 is formed in the guide projection 261 formed on the inner side of the end cap, and the cap main body is fitted to the cap main body. A guide groove 264 that engages with the guide protrusion 273 on the inner surface of the groove 27 is formed.

In order to assemble the slide rope 50 to the canvas take-up shaft J4, it is inserted in the axial direction along the back surface of the guide protrusion 172 of the inner rotary shaft 12, and the end caps 18A, 19A fitted in the front and rear positions are inserted. The rope passages 182 and 192 are once drawn outward from one of the rope passages 182 and 192, folded back to the outside, and then drawn out along the guide groove 171 at the front and rear position of the inner rotary shaft 12. Further, the end of the rope is pulled out from the through hole 263 of the end caps 24A and 25A of the outer roller 13, and the clips 501 and 502 are fitted to both ends of the rope to fix the end.
The other slide ropes 50 are also incorporated in the same manner, whereby four slide ropes 50 are stretched between the inside and the outside in the axial direction of the canvas take-up shaft J4.
Therefore, when the out roller 13 moves backward, the slide rope 50 at the front end is pulled out along the guide groove 171 of the inner rotary shaft 12 and the slide rope 50 exposed at the rear end is linked with the inner rotary shaft. 12 is pulled into the interior.
As a result, the canvas overhanging portions R2 and R3 wound around the inner rotary shaft 12 exposed by the backward movement of the outer roller 13 are exposed in the axial direction in the upper half portion, so that the slide rope 50 whose outer diameter is raised. Is indirectly wound around the outer peripheral surface of the.
For this reason, since the tight winding is not caused when the canvas overhang portions R2 and R3 are wound, the smooth movement of the outer roller 13 is ensured.
In addition, since the slide rope 50 is pulled out from the inner rotary shaft 12 in conjunction with the backward movement of the outer roller 13, it is possible to prevent rubbing against the canvas overhanging portions R2 and R3 wound around the outer periphery of the slide rope 50.

About the 5th example of canvas take-up shaft

Next, the canvas take-up shaft J5 of the fifth example shown in FIGS. 25 to 27 will be described.
Reference numeral 56 denotes a synthetic resin slide belt having appropriate elasticity and stretchability, and about four of them are incorporated in the axial direction of the inner rotary shaft 12.
18B and 19B are end caps fitted to the front and rear end portions of the inner rotary shaft 12, and each slide belt 56 is formed in a U-shape at an outer peripheral position from the cap main body portion to the lid portion. Belt passages 183 and 193 that are turned and turned are formed.
Reference numerals 24B and 25B denote end caps fitted to both front and rear ends of the outer roller 13. The cap collar portion is cut into four equal positions, and a slide belt 56 is formed in the surface axial direction of the cap body portion. A belt passage 265 for drawing in is formed.
Therefore, the slide belt 56 is inserted in the axial direction along the inner side surface of the guide protrusion 172 of the inner rotary shaft 12, and then pulled out from the inside of the belt passages 183 and 193 of the end caps 18B and 19B to the outside. After turning back, the belt is retracted along the belt passage 265 and both ends of the belt are fixed by clips 561 and 562.
The other slide belts 56 are also incorporated in the same manner, whereby four slide belts 56 are stretched around the canvas take-up shaft J5.
When the outer roller 13 moves backward, the slide belt 56 is pulled out to the shaft surface along the guide protrusion 172 of the inner rotating shaft 12 in conjunction with the outer roller 13, and the canvas overhanging portions R2 and R3 are indirectly connected to the slide belt 56. Wrapped around.
Thereby, the smooth forward and backward movement of the outer roller 3 is ensured, and rubbing against the canvas overhanging portions R2 and R3 is prevented.

  In order to electrify the canvas take-up shafts J4 and J5, components such as the electric motor 54, the bearing socket 55, and the end cap 19C shown in FIGS. ) Or FIG. 26 (C), or the inner rotary shaft 12 is assembled into one end cap 15 or 16 of the casing 11 by incorporating an electric motor (not shown). It will be electrified.

About the second embodiment of the corner awning device

Next, the corner awning device S2 of the second embodiment shown in the perspective views of FIGS. 28 (A) to (C), FIGS. 29 (D) and (F), and the plan views of FIGS. 30 (A) to (F). Will be explained.
This awning device S2 is one of the canvas tensioning device K2 of the second example provided with a pair of parallel two-stage swinging arms N1, N2 that rotate in a circular arc in a two-stage operation, and the canvas winding shafts J1 to J5 described above. Alternatively, it includes a canvas winding device M1 provided with any of canvas winding shafts J6 to J8 described later.
The two-stage swing arms N1 and N2 are composed of a rear arm 59 and a front arm 60 that are foldably connected. The intermediate portions of the swing arms N1 and N2 are connected by a connecting rod 61, and the arm front end is connected. The brackets 48 and 49 of the front bar 36 are pivoted.
Brackets 46 and 47 at the base end portions of the two-stage swing arms N1 and N2, that is, the base end portion of the rear arm 59, are incorporated with relatively weak spring elasticity, and the rear arm 59 and the front portion A relatively strong spring elasticity is incorporated in the bent connection portion of the arm 60.

Therefore, when the corner canvas G1 developed as shown in FIGS. 28A and 30A is wound around the canvas winding shafts J1 to J5, first, the corner canvas G1 is urged by a weak spring elasticity. A pair of the rear arms 59 starts to rotate back in a circular arc shape against the elastic urging force, and the rear bar 59 is moved diagonally rearward while moving the front arm 36 diagonally backward. Or it folds to the edge part of a wall through the rocking | fluctuation process shown to FIG. 30 (A)-(C).
Further, when the canvas take-up shafts J1 to J5 are taken up and rotated, the pair of front arms 60 urged by the strong spring elastic force moves the front bar 36 diagonally backward against the elastic urging force. While moving in parallel, the front arm 60 is folded to the side wall portion through the swinging process shown in FIGS. 29 (C) to (E) and FIGS. 30 (C) to (E).
On the contrary, when the canvas take-up shafts J1 to J5 are rewound, first, the pair of front arms 60 urged by a strong spring elastic force causes a circle in the forward expanding direction by the urging force. It rotates in the shape of an arc and pushes out the front bar 36 while moving it in a diagonally forward direction.
When the front arm 60 swings to the spread angle as shown in FIG. 28C or FIG. 30C, next, a pair of rear arms 59 biased by the weak spring elasticity rotate forward. By swinging to an expansion angle as shown in FIG. 28 (A) or FIG. 30 (A), the front bar 36 is pushed out while being translated further diagonally forward.
Thereby, the corner canvas G1 is developed and covered in the corner space.
Accordingly, when the front bar 36 is expanded and operated in two stages toward the corner space portion obliquely forward by the link mechanism including the two-stage swing arms N1 and N2 and the connecting rod 61, the first example is used. As compared with the case of the swing arms 44 and 45 incorporated in the canvas tensioning device K1, the front bar 36 can be pushed out further diagonally forward.

In this case, the angle connecting the base end portion and the front end portion of the two-stage swing arms N1 and N2 that press and urge the front bar 36 is practically about 70 to 80 as shown in FIG. The swing angle is adjusted so that the front arm 60 does not exceed 45 to 50 degrees, and the swing angle formed by the connecting rod 61 and the rear arm 59 does not exceed 120 degrees. In addition, rotation is restricted by an appropriate stopper (not shown) as required.

Therefore, when the inner rotary shaft 12 and the outer roller 13 are rotated together by the manual device, the outer roller 13 moves forward and backward in the axial direction while rotating through the meshing of the worm gear 91 and the worm rack 92, and at the same time, the outer roller 13 is moved back and forward while being slidably guided by the inner rotary shaft 12 by the tension of the canvas tension devices K1 to K5 and the tensile force of the connecting wires 34 and 35.
Thereby, the canvas main body R1 is wound around the outer roller 13, and the canvas overhanging portions R2 and R3 are wound around the inner rotary shaft 12 exposed by the backward movement of the outer roller 13.

Note that, when the corner canvas G1 is taken up or rewound on the canvas take-up shaft J6, the take-up diameter fluctuates, and the peripheral speed of the take-up shaft J6 gradually increases or decreases. In order to ensure the interlocking state with it, it is preferable to gradually widen the rack interval of the worm rack 92 toward the rear.
In the above case, since the outer roller 13 can be reliably moved forward and backward by the rack mechanism, the connecting wires 34 and 35 can be dispensed with.
The configuration other than the above is illustrated in the same manner as the canvas take-up shaft J1 of the first example, but the rack structure as described above is applied to any of the canvas take-up shafts J2 to J5 of the second to fifth examples. Can also be incorporated.

Therefore, when the electric motor is driven and the outer roller 13 rotates through the meshing of the bar gear 70 and the spur gear 69, the female screw 252 of the end cap 25C meshes with the rack 93 of the inner fixed shaft 12B. In addition, the outer roller 13 is slidably guided by the inner fixed shaft 12B by the elastic biasing force of the canvas tensioning devices K1 to K5, the tensioning force of the canvas G1, and the tensile force of the connecting wires 34 and 35, and moves backward. Move forward.
As a result, the canvas main body R1 is wound around the outer roller 13, and the canvas overhangs R2 and R3 are wound around the inner fixed shaft 12B exposed by the backward movement of the outer roller 13.

In the above-described case, the rack 93 that meshes with the female screw 252 is formed in the axial direction of the inner fixed shaft 12B. Instead, a spiral screw (not shown) on the outer peripheral surface of the inner fixed shaft 12B, that is, The outer roller 13 can be moved forward and backward by forming a male screw and engaging both the screws.
Further, instead of the female screw 252, an engaging projection (not shown) can be formed inside the end cap 25C, and the engaging projection and the male screw can be engaged and engaged.
In the case of the canvas take-up shafts J7 and J8 in the seventh and eighth examples, a manual drive device that directly drives the rear end portions of the drive gear 68 and the bar gear 70 is incorporated in the storage case 16A. You can also
Similarly, if the slide rope 50 and the slide belt 56 shown in the canvas winding shafts J4 and J5 of the fourth and fifth examples are incorporated in the canvas winding shafts J7 and J8, the canvas overhanging is performed in the same manner as those cases. The tight winding at the time of winding the portions R1 and R2 is prevented, and the smooth backward movement of the outer roller 13 is not impaired.

About the ninth example of canvas winding shaft

Next, the driven canvas take-up shaft J9 shown in FIG. 45 will be described.
77 is a coil spring inserted in the latter half of the inner rotary shaft 12, 78 is a disk-shaped spring retaining socket, and the tip 771 of the coil spring 77 is inserted into the through-hole 782 opened in the eccentric position. The rear end 772 is inserted into and supported by the through holes 192 opened at the eccentric position of the end cap 19.
Reference numeral 79 denotes a fixed shaft for penetrating and supporting the coil spring 77, which penetrates from the central through hole 190 of the end cap 19 to the coil spring 77, and its shaft tip 791 is inserted into the central through hole 781 of the spring stopper socket 78 and the shaft. The rear end portion 792 is fitted and fixed to the central through hole of the bearing portion 161 of the end cap 16.
Therefore, when the inner rotary shaft 12 rotates through the outer roller 13, the coil spring 77 is gradually compressed through the end cap 19 of the rotary shaft 12, and elastic energy is accumulated in the coil spring 77, or The stored elastic energy is released.

On the contrary, as the canvases G1 to G4 are deployed, elastic energy is gradually accumulated in the coil spring 77, and the maximum elastic biasing force is accumulated when the deployment is completed.

About the effect | action of the awning apparatus of 6th Example

Therefore, as shown in FIGS. 42 and 43, in order to wind the unfolded corner canvas G1 to G4 around the canvas winding shaft J9, an operation handle (not shown) is engaged with the hook 23 of the manual device and rotated. Then, the rotating shaft 73 rotates through the meshing of the bevel gears 752 and 751, and at the same time, the swing arms 44 and 45 are moved backward through the meshing of the worms 741 and 742 and the worm gears 761 and 762 at both ends. Rotate in a circular arc toward the front bar 36 to translate the front bar 36 diagonally backward.
At that time, the front bar 36 is tensioned by elastic energy necessary and sufficient to wind up the developed corner canvases G1 to G4.
Therefore, the restraining force by the swing arms 44 and 45 on the deployed canvas G1 to G4 is weakened, and at the same time, the elastic urging force of the coil spring 77 storing the maximum elastic energy is released when the deployment is completed.
As a result, the inner rotary shaft 12 and the outer roller 13 are integrally driven and rotated, and the canvas top sides 1, 1A fixed to the out roller 13 are wound.
In this way, the swing arms 44 and 45 on the driving side are rotated rearward, the front bar 36 is moved in parallel obliquely rearward, and at the same time, the tensile force of the connecting wires 34 and 35 is applied to the outer roller 13. The outer roller 13 is moved backward in the axial direction of the inner rotary shaft 12 by converting it into a rearward sliding force with respect to the inner rotational shaft 12.
As a result, the canvas body R1 is wound around the outer roller 13, and the canvas overhangs R2, R3 are wound around the inner rotary shaft 12 exposed as the outer roller 13 moves backward.

On the contrary, when the canvas G1 to G4 wound on the canvas winding shaft J9 is developed toward the corner space of the building, the wall edge portion is rotated by rotating the operation handle in the opposite direction. The two oscillating arms 44 and 45 folded into the arc rotate in an arc shape in the expanding direction, and push the front bar 36 attached to the front end of the arm in parallel toward the corner space portion diagonally forward. .
Along with this, the inner rotating shaft 12 and the outer roller 13 rotate together in reverse, and the elastic energy is accumulated by compressing the coil spring 77 while rewinding the corner canvas G1 wound around the canvas winding shaft J1. To do.
Further, a sliding force in the forward direction with respect to the outer roller 13 acts by the rotational force of the swing arms 44 and 45 acting on the front bar 36 and the tensile force of the connecting wires 34 and 35 to be rewound, and the outflow The roller 13 rotates in the reverse direction while moving forward along the inner rotary shaft 12.
As described above, the front bar 36 is pushed obliquely forward by the rotational force of the swing arms 44 and 45, the inner rotary shaft 12 and the outer roller 13 are integrally rotated in reverse, and the outer roller 13 is moved forward. The canvas G is pushed toward the corner space part diagonally forward.

85 is a retaining washer fitted into the rear end portion of the pipe shaft 81, and supports the lid plate 82, the spiral spring 83, and the slide case 84 that are fitted into the pipe shaft 81 sequentially. Reference numerals 241 and 251 denote through holes of the inner fixed shaft 12B, 821 denotes a through hole of the cover plate 82, and 841 denotes an end through hole of the slide case 84.
Accordingly, when the outer roller 13 inserted and supported so as to be slidably guided on the inner fixed shaft 12B rotates, the spiral spring 83 is gradually compressed through the end cap 25C of the outer roller 13, and elastic energy is applied to the spring 83. The stored elastic energy is released.
Specifically, when the winding of the canvas G1 to G4 to the canvas winding shaft J10 is completed, the elastic energy is released with a slight preload.
On the contrary, as the canvases G1 to G4 are deployed, elastic energy is gradually accumulated in the spiral spring 83, and the maximum elastic biasing force is accumulated when the deployment is completed.

It is a sheet magnet fixed to the edge of the G4 canvas near the oblique sides 3, 5, 5A. The outer roller 13 is made of a nonmagnetic material.
Therefore, when the canvas overhanging portions R2, R3 are wound around the outer peripheral surfaces of the inner shafts 12, 12A, 12B exposed by the backward movement of the outer roller 13, the canvas hypotenuses 3, 5, 5A are repelled by magnetic force and magnetically levitated. By doing so, the tight winding is prevented, and the smooth movement of the outer roller 13 is ensured.
In this case, the sheet magnet can be fixed to the inner peripheral surface of the outer roller 13 and the sheet magnet 94 can be fixed over the entire outer peripheral surface of the inner shafts 12, 12A, 12B.
In that case, the outer roller 13 is supported in a magnetically levitated state with respect to the inner shafts 12, 12 </ b> A, 12 </ b> B, and the sliding resistance during the forward / backward movement of the outer roller 13 is eliminated or greatly reduced. Thus, the forward / backward movement of the outer roller 13 is remarkably smooth.

About other variations of corner canvas

Finally, some modifications of the corner canvas G1 to G4 will be added.
50 (A) to 50 (C), 86 is a border sheet fixed on the surface side near the canvas hypotenuse 3, 5, 5A, and its film thickness is continuously increased from the top side to the canvas base 2, 2A. The thickness gradually increases.
Therefore, when the canvas overhang portions R2 and R3 are wound around the outer peripheral portions of the inner rotary shafts 12 and 12A and the inner fixed shaft 12B exposed by the backward movement of the outer roller 13, the portion of the sheet 86 is As shown in the cross-sectional view of FIG.
As a result, the canvas overhang portions R2 and R3 are prevented from being tightly wound around the outer peripheral surfaces of the inner rotary shafts 12 and 12A and the inner fixed shaft 12B, and the spacer function by the edged sheet 86 wound spirally Is ensured and the smooth movement of the outer roller 13 is ensured.
In the above case, the border sheet 86 is gradually thickened. However, the thickness may be increased step by step for every turn or every two turns.

In FIG. 51, 89 is a strip-like aggregate having spring elasticity, and is sewn and fixed inside the canvas in the form of horizontal stripes from the canvas body R1 to the canvas overhangs R2 and R3, or It is inserted into the bag passage formed in a horizontal stripe shape.
Therefore, if the canvas G1-G4 incorporating the aggregate 89 is wound around the outer roller 13, between the inner shafts 12, 12A, 12B having a smaller diameter and the outer peripheral surfaces of the canvas overhang portions R2, R3, It is wound around a slight gap.
Therefore, smooth movement of the outer roller 13 is ensured and rubbing against the canvas overhang portions R2 and R3 is prevented.

52 (A) and 52 (B), reference numerals 87 and 88 denote connecting belts that are sewn and fixed on diagonal lines connecting the four corners of the canvas body R1 diagonally, and are passed through the belt ends protruding from both ends thereof. Holes 871, 872, 881, and 882 are provided.
Therefore, when the canvas top sides 1, 1A of the corner canvas G1 to G4 are attached to the outer roller 13 and the canvas bottom sides 2, 2A are attached to the front bars 36, 36A, the respective engagement holes 271, 272, 39, 40 are provided. It is fixed by screwing a screw (not shown).
In the above case, the connecting belts 87 and 88 are fixed to the canvas body R1 in an X shape. However, as shown in FIG. 53, the connecting belts 87A and 88B are sewn and fixed in an inverted V shape, or Instead of a belt, a rope can be used, or the connecting wires 34 and 35 can be fixed in an X shape or a V shape.
