Description

  The present invention relates to an awning device that opens, closes, holds, and stores an opening / closing body such as a canvas for sunshade and rain protection in stores, etc., particularly when the left and right arms have different extension postures. The present invention relates to an awning device that can stretch a canvas.

  FIG. 1 is a diagram showing a schematic configuration of a conventional awning apparatus. As shown in FIG. 1, for example, the awning device is attached to an outer wall of a building such as a store or a residential house via an attachment bracket 101. In FIG. 1, only the left side of the awning device is shown as a perspective view, and the configuration of only the left side shown will be described, but it is needless to say that a similar configuration exists on the right side. Omitted. The mounting bracket 101 has an E shape in which the upper side is long and the middle side and the lower side have the same length. A prismatic arm support frame 103 is fastened and fixed by bolts and nuts between the middle side and the lower side of the E-shaped mounting bracket 101. Near the left and right ends of the arm support frame 103, and inside the mounting bracket 101, link type joint arms 105 and 106 having a degree of freedom are attached via arm brackets 107. One end of the joint arm 105 and one end of the joint arm 106 are rotatably coupled via a joint member.

  The other end of the joint arm 105 is coupled to the arm bracket 107 via a joint member, and the other end of the joint arm 106 is rotatably coupled to the canvas support front frame 108 via the joint portion. Although not shown, the joint arms 105 and 106 have elastic bodies such as a tension coil spring that applies an urging force to extend the joint arms 105 and 106. Accordingly, the canvas support front frame 108 is always applied with an urging force to extend forward by the joint arms attached to the left and right. The canvas support front frame 108 is attached to one end side of a canvas 109 made of a synthetic fiber cloth that serves as a sunshade or rain cover. The other end side of the canvas 109 is wound around the winding pipe 110. The winding pipe 110 is rotatably supported by end brackets 111 attached to both ends of the arm support frame 103.

  The winding pipe 110 has a hollow pipe shape. When the awning device is electrically opened and closed, a rotary motor as a drive source is provided at either end of the winding pipe 110. The rotary motor is not shown because it is in the winding pipe 110. The outer side of the main body of the rotary motor and the inner side of the take-up pipe 110 are fixed, and the output shaft of the rotary motor is fixed to the end bracket 111 with bolts or the like. Accordingly, when the rotation motor rotates in the forward direction, the canvas 109 operates so as to be fed out, and when rotated in the reverse direction, the canvas 109 operates so as to be wound up. That is, the opening / closing operation of the canvas 109, which is an opening / closing body, is controlled by rotating the rotary motor in the forward and reverse directions.

  The cover plate includes an upper cover 112 and left and right side covers 113 and 114. The upper cover 112 is composed of a plate material made of a curved aluminum alloy or the like whose front edge is curved downward and whose cross-sectional shape is substantially J-shaped, and the lower surface near both ends is attached to the mounting bracket 101 (on the right side). Are attached to the upper end of the cover plate but are not shown in the figure, and cover the take-up pipe 110 and the canvas 109 wound around it from above, and the side covers 113 and 114. Covers the left and right outer surfaces. Since the upper cover 112 is long in the left-right width direction, a substantially L-shaped support bracket is provided at a substantially intermediate position to prevent the deflection thereof so as to support the upper cover 112. Yes. The support bracket is not shown.

  This awning device is configured to be able to electrically open and close the canvas 109 and to manually open and close the canvas 109 via the manual gear 115 and the crank ring 116. As shown in FIG. 1, there are three types of awning devices: an electric manual type that opens and closes both electrically and manually, an electric type that opens and closes only by electricity, and a manual type that opens and closes only manually. To do.

  2 is a diagram showing a schematic configuration of an arm angle adjusting mechanism of the awning device of FIG. 1, and is a view of the awning device of FIG. 1 as viewed from the left side surface. In FIG. 2, the side cover 113, the manual gear 115, and the crank ring 116 are not shown. When adjusting the angles of the joint arms 105 and 106, that is, the stretching angle of the canvas 109, the attachment angle of the arm holder 117 attached to the arm bracket 107 is adjusted. To adjust the mounting angle, the fixing bolt 118 for pressing and fixing the arm holder 117 to the side surface of the arm bracket 107 is loosened with a spanner, the hexagonal bar spanner 120 is set in the lower hole of the arm bracket 107, and is built in the arm bracket 107. This is done by rotating the angle adjustment bolt 119. That is, the angle of the arm holder 117 with respect to the arm bracket 107 can be adjusted by rotating the angle adjusting bolt 119. Such angle adjustment uses the angle marks engraved on the side surface of the arm bracket 107 as a guide, and the left and right joint arms 105 and 106 are alternately arranged so that the left and right joint arms 105 and 106 have substantially the same angle. It is necessary to adjust gradually. When the fine adjustment of the left and right joint arms 105 and 106 is completed, the angle adjustment is completed by tightening the fixing bolt 118 with a spanner.

As an awning device with such an angle adjustment mechanism, there is one as shown in Patent Document 1. Japanese Patent Application Laid-Open No. H10-228561 reduces the manufacturing cost by reducing the number of constituent members of the product set, and makes it possible to easily adjust the angle while visually observing the inclination angle of the awning.
Japanese Patent Laid-Open No. 08-246629

  The arm angle adjusting mechanism of the awning device shown in FIG. 2 uses a tool such as a spanner to loosen the fixing bolt 118 and the angle adjusting bolt 119 built in the arm bracket 107 (in other words, as an operating tool for this awning device). The angle of the arm holder 117 is adjusted by rotating it with a hexagonal bar wrench 120, and the arm angle is adjusted by tightening the fixing bolt 118 after the adjustment. Similarly, the arm angle adjusting mechanism described in Patent Document 1 is tilted by loosening the bolts with a tool such as a spanner and rotating the two angle adjusting bolts provided above and below the arm mounting portion with a tool such as a spanner. The angle of the member (arm holder) is adjusted, and after the adjustment, the bolt is tightened to adjust the angle of the arm.

  In the conventional awning device, the arm tip and the front frame are fixedly provided. Therefore, when adjusting the angle of the arm, that is, the angle of stretching and holding the canvas, the difference in angle between the left and right arms is about 5%. Therefore, when adjusting the arm angle, the left and right arms are adjusted almost simultaneously, or the left and right angles are not adjusted gradually. It was difficult to change.

  The present invention has been made in view of the above-described points, and an object thereof is to provide an awning device that can easily stretch a canvas even when left and right arms have different extension angles.

The first feature of the awning device according to the present invention is that the arm bracket means for adjusting the mounting angle of the arm support means for supporting the arm means by adjusting the amount of rotation of the angle adjusting means, and the distal end portion of the arm means A front frame means that is held by a front frame holding means attached to the front frame means; an opening / closing body means fixed to the front frame means; and by winding or unwinding the opening / closing body means, In an awning device comprising a winding means for performing an opening and closing operation, when the left and right attachment angles of the arm support means are different by the angle adjustment means, and the posture of the arm means is twisted, the front frame holding means is The arm means is attached to the arm means via an arm cap means configured to pivot and allow torsion with respect to the arm means Some that are.
In the conventional awning device, the front end portion of the arm means and the front frame holding means are fixed to each other, so that the left and right arm means are twisted by the angle adjustment, and the angle difference becomes about 5 degrees or more. A torsional stress is generated between the arm means and the front frame holding means provided in a fixed manner, and the arm means and / or the front frame holding means may be damaged. In the present invention, since the arm cap means configured to rotate with respect to the arm means and maintain the posture of the front frame holding means is provided, the left and right arm means are twisted by the angle adjustment, and about 30 degrees at the maximum. Even when the angle difference (twist) is about a degree, the twist can be allowed by the pivoting movement of the arm cap means, so that no torsional stress is generated between the arm means and the front frame holding means. Can be stretched canvas. In the awning device of the present invention, an operation of stretching (stretching) a canvas as an opening / closing body is called an opening operation, and an operation of storing the canvas is called a closing operation.

A second feature of the awning device according to the present invention is the awning device according to the first feature, wherein the front frame holding means is an insert whose horizontal axis is fixed to the front frame means and whose vertical axis is a round bar-like insert. The arm cap means is a hole through which the round bar-like insert portion is inserted, and has a shape in which two conical apexes are overlapped, The portion having the smallest inner diameter has an insertion hole configured to substantially match the outer diameter of the insert portion, and the upper and lower end portions of the arm cap means are formed in a spherical shape, and the insertion portion is inserted into the insertion hole. The insert portion is attached by being clamped from above and below via spherical washer means configured to match spherical portions formed at both upper and lower ends of the arm cap means. Is that is configured to freely pivot moving the insertion hole of the smallest part of the inner diameter of the insertion hole as the center (supporting point).
This is a more specific configuration of the front frame holding means and the arm cap means described in the first feature, wherein a part of the front frame holding means is constituted by a round bar-shaped insert portion. The part is inserted into the insertion hole of the arm cap means. Since this insert part pivots and moves freely in the insertion hole with the smallest inner diameter of the insertion hole as the center (fulcrum), even if the left and right arm means are twisted by angle adjustment, the insert part is the insertion hole of the arm cap means Since it is swiveled inside, the amount of twist can be allowed. In the present invention, the shape of the insertion hole is a case where two conical apexes are overlapped, but this is only an example, and the insert part is a fulcrum (center) in the insertion hole. ) As long as it can be turned at a predetermined angle, the shape is not limited to a conical shape, and various shapes such as a triangular pyramid shape, a quadrangular pyramid shape, and a combination of circles having different diameters are applicable. .

  A third feature of the awning device according to the present invention is that, in the awning device according to the first or second feature, the pivotable angle of the insert portion is equal to or greater than the value of the angle adjustment range of the arm means. It is in. This makes it possible to easily adjust the angle of the arm without worrying about the pivotable angle of the insert portion by making the pivotable angle of the insert portion larger than the angle adjustment range of the arm.

  According to a fourth aspect of the awning device of the present invention, in the awning device according to the first, second, or third feature, the apex angle of the conical shape is about 30 degrees, so that the inside of the insertion hole The swivel angle of the insert part that swivels freely is within about 30 degrees. In consideration of the fact that the angle adjustment range of the arm means is about 30 degrees, the apex angle of the conical shape for specifying the shape of the insertion hole is set to about 30 degrees.

  According to the awning device of the present invention, there is an effect that the canvas can be easily stretched even when the extension angles of the left and right arms are different.
