According to the urging mechanism 50, the rear arm 41 and the front arm 42 are urged in the deploying direction (extending direction) by the urging force of the urging mechanism 50 when no force is applied to the telescopic arm 40. Further, when the canvas 10 is wound around the winding body 20 and a compressive force in the front-rear direction is applied to the telescopic arm 40, the tension spring 51 is extended and the rear arm 41 and the front arm 42 are bent. It rotates as follows.

The power transmission cutting unit 60 (power transmission cutting mechanism) is a mechanism for transmitting the power applied to the input member 64 to the winding body 20 and for separating the power transmission path by an external force.
This power transmission cutting unit 60 is engaged in a case 61 so as to rotate integrally with a worm wheel 62 that rotates in conjunction with the winding body 20, a worm 63 that meshes with the worm wheel 62, and the worm 63.

According to the illustrated example, the half piece 61a is formed in a substantially rectangular shape in plan view having a concave accommodation space near the center. A through hole 61a1 is provided on the bottom surface of the housing space in the half piece 61a for rotatably inserting a rotary shaft 71a of a damper mechanism 71 described later.
The other half 61b is formed in substantially the same shape as the half piece 61a, overlaps with the half piece 61a, and is fastened and fixed by a fastening tool such as a bolt to close the accommodation space.

The worm wheel 62 is a helical gear that constitutes a worm gear mechanism. The worm wheel 62 is annularly mounted on the rotating shaft 71a of the damper mechanism 71 that passes through the half half 61a, and rotates integrally with the rotating shaft 71a.
According to the illustrated example, the rotating shaft 71a is formed in a prismatic shape, and the worm wheel 62 is fitted concentrically with the prismatic rotating shaft 71a.

The worm 63 is a screw gear that meshes with the worm wheel 62 to constitute a worm gear mechanism.
An input member 64 is inserted through the shaft portion of the worm 63 in a penetrating manner. The worm 63 is attached to the input member 64 so as to be integrally rotatable and axially movable.
According to the illustrated example, the upper side of the input member 64 is formed in a prismatic shape. A square hole (not shown) slightly larger than the outer peripheral portion of the prismatic input member 64 is provided on the center side of the worm 63. The worm 63 has the square holes fitted in a ring shape with respect to the prismatic input member 64.

  The input member 64 is integrally rotated from an operating shaft portion 64a that is rotated from below and a transmission shaft portion 64b that is linearly connected to the upper end of the operating shaft portion 64a and transmits the rotational force of the operating shaft portion 64a. Configured to be possible.

  The operation shaft portion 64a is formed in a cylindrical shaft shape from a hard material such as metal, and has an annular portion 64a1 for hooking a manual operation rod (not shown) having a tip hook shape on the lower end side thereof.

  The transmission shaft portion 64b includes a circular shaft portion 64b1 on the lower half side, an annular flange portion 64b2 projecting annularly on the upper side of the circular shaft portion 64b1, and a rectangular axis coaxially continuous on the upper side of the annular flange portion 64b2. The portion 64b3 and the rotating shaft portion 64b4 that is coaxially continuous on the upper side of the angular shaft portion 64b3 are configured in an integral substantially shaft shape.

The circular shaft portion 64b1 is formed in a columnar shape or a cylindrical shape. An operation shaft portion 64a is coaxially connected and fixed to the lower end side of the circular shaft portion 64b1. A cylindrical holding member 66 is mounted on the upper end side of the circular shaft portion 64b1 so as to be movable up and down.
Further, an annular elastic body 64c is annularly attached to the circular shaft portion 64b1 so as to be positioned between the holding member 66 and an annular flange portion 64b2 described later. According to the illustrated example, the annular elastic body 64c is an elastic body such as a plurality of O-rings. As another example of the annular elastic body 64c, a coil spring or another annular or cylindrical elastic body can be used.
In order to reduce the frictional resistance between the annular elastic body 64c and the annular flange 64b2, one or a plurality of washers 64c1 are mounted.

  The annular flange portion 64b2 is located between the circular shaft portion 64b1 and the angular shaft portion 64b3, and protrudes in an annular shape radially outward from the outer peripheral surface of the angular shaft portion 64b3. The annular flange 64b2 is not rotatable and axially movable with respect to the angular shaft portion 64b3, and is formed integrally with the angular shaft portion 64b3 by machining according to the illustrated example.

  The square shaft portion 64b3 has an outer peripheral surface formed in a prismatic shape. A worm 63 is mounted on the angular shaft portion 64b3 so as to be movable up and down and integrally rotatable, and a second urging member 69 is mounted on the upper side of the worm 63 in an annular shape.

  The rotation shaft portion 64b4 has an outer peripheral surface formed in a columnar shape. A washer 64d and an O-ring 64e are annularly attached to the rotating shaft portion 64b4. And the part above this washer 64d and O-ring 64e in this rotating shaft part 64b4 is inserted in the substantially cylindrical support member 65. As shown in FIG.

The support member 65 is a substantially bottomed cylindrical member whose upper portion is closed. The support member 65 is annularly attached to the rotation shaft portion 64 b 4 at the upper end of the input member 64 and is rotatably fitted to the input member 64.
Further, the upper end side of the support member 65 is annularly attached to the shaft member 64f so as to rotate around the shaft member 64f supported by the case 61 (specifically, the half portion 61a) which is a stationary part. It is. The shaft member 64f is a shaft-like member that protrudes substantially vertically from the half portion 61a of the case 61 to the inside of the case. According to the illustrated example, the shaft member 64f is a bolt that penetrates the half portion 61a in the thickness direction.

The holding member 66 is a cylindrical member that is fitted in an annular shape around the circular shaft portion 64b1 so as to move in the vertical direction with respect to the circular shaft portion 64b1.
A first urging member 67 and a lever member 68 which will be described later are fixed to the outer peripheral portion of the holding member 66.

  The first urging member 67 is a coil spring. The first urging member 67 is disposed on the worm wheel 62 side (left side according to FIG. 3) with the input member 64 as a boundary, and one end side of the first urging member 67 is a stationary part 61 (specifically, a half part) 61a), and the other end is fixed to the holding member 66, and the worm 63 is urged in the approaching direction in which the worm 63 is engaged with the worm wheel 62.

The lever member 68 is disposed on the opposite side (right side according to FIG. 3) of the worm wheel 62 with the input member 64 as a boundary. When the lever member 68 is rotated, the lever member 68 pulls the holding member 66 so as to oppose the urging force of the first urging member 67.
More specifically, according to the illustrated example, the lever member 68 is formed in an inverted triangle shape having pivoting portions 68b and operated portions 68c on both sides of the rotation fulcrum portion 68a.
The rotation fulcrum portion 68a is pivotally supported by a shaft-like member such as a bolt with respect to the half half portion 61a of the case 61 which is a non-moving portion.
The pivot part 68b is rotatably connected to the holding member 66 via a shaft-like member or the like.
The operated portion 68c is provided with a through hole, and one end side of the string-like member 68d is fixed to the through hole. The other end side of the string-like member 68d is hung downward.
According to a preferred example of the present embodiment, the lever member 68 has a dimension (distance) from the rotation fulcrum part 68a to the operated part 68c rather than a dimension (distance) from the rotation fulcrum part 68a to the pivot attachment part 68b. ) Is long. According to this configuration, the input member 64 can be rotated by a relatively light pulling operation on the string-like member 68d, and the operability is good.
In the illustrated example, the lever member 68 exposes the operated portion 68c to the outside. However, as another example, the operated portion 68c is disposed in the case 61 and the string-like member 68d is disposed in the case 61. It is also possible to adopt a mode in which it is pulled in and connected to the operated portion 68c.

The second urging member 69 is a coil spring that is annularly inserted into the angular shaft portion 64 b 3 of the input member 64, and urges the worm 63 downward relative to the input member 64.
More specifically, the upper end portion of the compressed second urging member 69 is in contact with the lower end of the support member 65 through the washer 64d and the O-ring 64e. Further, the lower end portion of the second urging member 69 is in contact with the upper end portion of the worm 63. Accordingly, the worm 63 is urged downward by the second urging member 69, and the lower end thereof is brought into contact with the annular flange 64b2.

The damper mechanism 71 includes a substantially disc-shaped main body portion 71b and a rotation shaft 71a that rotates relative to the main body portion 71b, and provides resistance to rotation in only one direction of the rotation shaft 71a due to the viscous resistance of the fluid. This is a well-known one-way type rotary damper. The damper mechanism 71 applies resistance to the rotation of the winding body 20 and releases the resistance when the winding body 20 rotates in the reverse direction.
The rotating shaft 71 a passes through the main body 71 b, and a prismatic part at one end thereof is inserted into the case 61 of the power transmission cutting unit 60 and is fitted to the center of the worm wheel 62. A rotating core 72 is coaxially fixed to the other end side of the rotating shaft 71a.

  The rotating core 72 is a cylindrical member, and is fixed to the rotating shaft 71a so as not to rotate. The winding body 20 is fitted on the outer periphery of the rotating core 72 in an annular shape so as to be integrally rotatable.

  In FIG. 1, reference numeral 24 denotes a side cover that covers the side of the winding body 20. Reference numeral 25 denotes a top cover that covers the upper side of the winding body 20.

In FIG. 1, reference numeral 53 denotes a swing mechanism that swings each telescopic arm 40 in the vertical direction between each telescopic arm 40 and the support base 21.
The swing mechanism 53 includes a mechanism for manually swinging the telescopic arm 40 up and down (see, for example, Japanese Patent Application Laid-Open No. 2010-24761), or a mechanism for electrically swinging the telescopic arm 40 up and down (for example, a special feature). For example, see Japanese Laid-Open Patent Publication No. 2013-19483). It is also possible to omit the swing mechanism 53 so that the telescopic arm 40 does not swing.

Next, the characteristic operation and effect of the awning device A having the above configuration will be described in detail.
First, in the stored state in which the left and right telescopic arms 40 are contracted and the canvas 10 is wound around the winding body 20, the worm wheel 62 is engaged with the worm 63 as shown in FIG. Is held non-rotatable.

  In this state, if the string-like member 68d is pulled downward and the lever member 68 is rotated in one direction (clockwise in the illustrated example), the rotation is performed as shown in FIGS. The holding member 66 is pulled by the lever member 68. At this time, the holding member 66 contracts the annular elastic body 64c and moves in the direction away from the worm wheel 62 while moving upward along the input member 64 (in the illustrated example, right diagonally upward).

  Therefore, the input member 64 inserted into the holding member 66 rotates about the shaft member 64f, the worm 63 is separated from the worm wheel 62, and the meshed state of the worm 63 and the worm wheel 62 is released. The

For this reason, the worm wheel 62, the rotary core 72, and the winding body 20 are in a freely rotatable state. Thereafter, both the telescopic arms 40 are extended by the urging force of the urging mechanism 50, and the support front frame 30 moves forward. As a result, the canvas 10 is fed out from the winding body 20, and the winding body 20 is moved. It rotates in the feeding direction.
The rotational speed at this time is suppressed by the resistance of the damper mechanism 71. Therefore, the canvas 10 is gradually projected forward.

When the downward tension force on the string-like member 68d is loosened during the extension operation of the canvas 10 or after the extension of the canvas 10 is completed, the lever member 68 is moved in the reverse direction by the tensile force of the first urging member 67. And the input member 64 is rotated in the reverse direction (leftward according to FIG. 5) so that the input member 64 returns to the original state, and the worm 63 is engaged with the worm wheel 62. For this reason, the rotation of the worm wheel 62 and the winding body 20 is stopped, and the feeding operation of the canvas 10 is also stopped.
When the lever member 68 is rotated in the reverse direction and the input member 64 is also rotated in the reverse direction, the holding member 66 is smoothly moved downward by the elastic force of the annular elastic body 64c. Return to position.

In addition, during this stop, when a rotational force is applied to the input member 64 so as to wind and rotate the winding body 20, the input member 64 applies the rotational force to the support member 65 and the holding member 66. The worm 63 also rotates in the same direction. In this winding operation, the resistance of the unidirectional damper mechanism 71 is not received.
For this reason, the worm wheel 62 is also meshed with the rotating worm 63, the rotating shaft 71a, the rotating core 72 and the winding body 20 are rotated in the same direction, and the canvas 10 is wound around the winding body 20, Both telescopic arms 40 contract.

If the rotational force applied to the input member 64 continues after the winding body 20 winds up the canvas 10, the worm 63 rises against the urging force of the second urging member 69. The worm wheel 62 moves upward. For this reason, it is possible to prevent the winding body 20 from damaging the canvas 10 due to excessive winding.
In addition, even when the input member 64 is mistakenly rotated in the opposite direction in an attempt to rotate the winding body 20 after the canvas 10 has been fully extended by the above-described overhanging operation, the worm 63 is moved to the second direction. Since it rises against the urging force of the urging member 69 and disengages upward from the worm wheel 62, it is possible to prevent the winding body 20 from reversely winding the canvas 10.
The effects such as the rise of the worm 63 are the same as the invention described in Patent Document 1.

  Therefore, according to the awning apparatus A, the canvas 10 is desired only by operating the lever member 68 without using an electric drive source such as a motor or continuously rotating a manual operation rod (not shown). Can be easily extended to the position.

In addition, according to the said embodiment, although the expansion-contraction arm 40 was comprised from two arms, the rear arm 41 and the front arm 42, as another example of the expansion-contraction arm 40, it was set as the 3 or more arms made to bend. It is also possible to adopt an aspect.
Furthermore, as another example of the telescopic arm 40, it is also possible to provide a single arm in which the rear end side is pivotally supported on the stationary part and the front end side is pivotally supported on the support front frame 30. According to this other example, since the one arm rotates with the pivot point on the rear end side as a fulcrum, the support front frame 30 at the front end of the arm can be moved in the front-rear direction.
Furthermore, as another example of the telescopic arm 40, it is also possible to adopt a mode in which a plurality of cylindrical members overlapped inside and outside are slid to extend and contract.

Further, according to the above-described embodiment, the tension spring 51 and the wire 52 are used as the biasing mechanism 50 for expanding and contracting the telescopic arm 40. As another example of the biasing mechanism 50, the rear arm 51 and the front arm are used. Other structures such as a mode in which a torsion coil spring, a leaf spring, or the like is provided in a portion that pivotally supports 52 are also possible.
Furthermore, as another example of the urging mechanism 50, it is possible to omit the tension spring 51 and the wire 52 and to extend the telescopic arm 40 only by the weight of the front side portion of the telescopic arm 40 and the support front frame 30. It is.

  Further, according to the above-described embodiment, the power transmission path between the worm wheel 62 and the worm 63 is cut. However, as another example, the input member 64 and the winding body 20 are separated by another clutch mechanism (not shown). It is also possible to cut the power transmission path between the two.

  Further, according to the above embodiment, the rotary damper is used as the damper mechanism 71. However, as another example of the damper mechanism 71, it is also possible to use a direct acting damper combining a piston, a cylinder, and the like. .

  Further, the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention.
