Description

The present invention relates to a awning. More specifically, the present invention relates to a simple installation type awning particularly suitable for application to a paragola type awning.

Conventionally, there has been a paragola type awning having a skeleton composed of four columns and four girders and a awning sheet that is supported by a rectangular roof frame portion of the skeleton and can be opened and closed (for example). , Patent Document 1). Since this awning is intended for permanent installation, it is installed by adopting a strong frame structure and firmly fixing it to the ground as a measure against strong winds.

Japanese Unexamined Patent Publication No. 2014-169563

However, the method of using the awning is not limited to the permanent installation. For example, there are various ways to use it, such as installing it only during the hot summer months, or installing it at an event for a limited time. In this case, a simple tent or the like is often installed, but since the tent cannot be opened and closed in the tent, there are restrictions on how to use it. In other words, it is required to easily install a awning that can open and close the tent as needed.

By the way, in the installation of the awning, it is required to install the girder on the support column substantially horizontally not only in terms of appearance but also in order to allow the awning sheet to be opened and closed smoothly. However, in the case of the simple installation type awning that is temporarily installed, unlike the awning that is premised on permanent installation, the entire ground of the awning installation location or at least the installation location of the support column is leveled and leveled to the height. It is difficult to ensure the levelness of the girders by adjusting the height or cutting the length of the support column itself, both in terms of cost and period. Therefore, there is a need for a strut adjustment mechanism that can easily adjust the inclination of the girder.

The present invention meets such a demand, and provides a simple installation type awning that can easily and quickly adjust the height of a support column and can open and close the awning sheet by installing the girder horizontally. The purpose.

In order to achieve such an object, the present invention is a simple installation type in which a awning sheet that can be opened and closed between an open state and a closed state is supported by a frame composed of a plurality of columns and a girder straddling the columns. In the awning, each column can be expanded and contracted independently, and it has a fixing mechanism that can fix the expansion and contraction length of the column at multiple positions, and the expansion and contraction length of multiple columns can be fixed in each column. By expanding and contracting the columns, the unevenness of the ground is adjusted to keep the girder horizontal.

Here, the telescopic structure of the strut is preferably a telescopic structure in which the lower strut is housed inside the upper strut.

Further, it is preferable that the support column fixing mechanism is fixed by inserting a convex portion protruding from the upper support column side into a plurality of holes provided in the lower support column.

According to the simple installation type awning according to claim 1, since the height can be adjusted independently for each support column as needed, the height can be changed for each support column as needed. For example, you can extend only the pillars where the ground is low and floating so that they touch the ground, or conversely, when the ground is high, shorten the pillars so that they cannot be pushed up. Even if the ground level of the support column installation location is not flat (horizontal slope, etc.) by adjusting the height, it is possible to eliminate the rattling and tilting of the entire frame. Then, the awning height can be set to a desired height, and the awning can be installed by maintaining the upper girder of the support column horizontally.

Hereinafter, the configuration of the present invention will be described in detail based on the embodiments shown in the drawings. In the present embodiment, the direction in which the awning sheet is opened is the front direction, the direction in which the awning sheet is closed is the rear direction, and the left and right sides are defined based on the front facing state.

FIG. 1 shows an example of an embodiment in which the awning of the present invention is applied to a four-post paragola type awning. The paragola type awning according to this embodiment includes a skeleton 1 assembled in a rectangular parallelepiped shape and a foldable awning sheet 6 stretched on the skeleton 1.

The skeleton 1 includes, for example, a strut 2 that can be expanded and contracted between at least a low position and a high position and is fixed at least at a high position, girders 3 and 4 having both ends supported by the strut 2, and strut 2 and a girder. It is provided with a corner joint 5 that straddles between the column 4 and between the girder 3 and the girder 4 and surrounds the corner where the column 2 and the girders 3 and 4 in two directions orthogonal to each other intersect. And the corner joint 5 are connected to each other to be assembled. The awning using this skeleton 1 is completed by assembling the skeleton 1 with the strut 2 contracted to a low position, attaching the awning sheet 6 to the skeleton 1, and then extending all the struts 2 to a high position. The awning sheet 6 is stretched at a high position. In the case of the present embodiment, four girders of four columns 2, front and rear girders (hereinafter referred to as side girders 3), left and right girders provided with rails (hereinafter referred to as rail girders 4), and columns. A paragola-type awning skeleton 1 is composed of a corner joint 5 that surrounds a corner where 2 and girders 3 and 4 intersect.

Here, the support column 2 has a structure that can be expanded and contracted. For example, as shown in FIG. 13, by combining prisms of different sizes to form a nested telescopic structure (telescopic structure) in which the other prism is slidably connected to one prism. The support column 2 is provided so as to be expandable and contractible. From the viewpoint of expanding and contracting the support column 2, any square tube may be large, but in the present embodiment, the lower corner inside the upper square tube, that is, the upper support column (hereinafter referred to as the telescopic column 2a). As a telescopic structure in which a cylinder, that is, a lower support column (hereinafter referred to as a slide column 2b) is accommodated, rainwater or the like is provided so as not to enter and collect inside the support column 2 through a gap between the slide column 2b and the telescopic column 2a. Has been done. The telescopic column 2a as the upper column and the slide column 2b as the lower column constituting the telescopic structure are not limited to the square cylinder shown in the figure, and may be a cylinder, an elliptical cylinder, or a polygonal cylinder in some cases. good.

FIG. 13 shows an example of the cross section of the square cylinder serving as the support column 2. The telescopic pillar 2a on the upper side of the pillar 2 is, for example, a square cylinder having a square cross section. On the other hand, the slide column 2b on the lower side of the column 2 is, for example, a square tube having a size that fits inside the telescopic column 2a and has a substantially square cross section, and a recess 13 that is continuous in the longitudinal direction at the center position in the width direction of one side surface. Is provided. The recess 13 is for passing the lock pin 11c at the tip of the telescopic stopper 11 in the vertical direction (to prevent interference during relative movement), and it is sufficient if it exists at least within the relative movement range of the lock pin 11c. In the case of the present embodiment, it is preferable that the square cylinder is provided over the entire length of the square cylinder because the square cylinder is formed by extrusion molding.

Between the telescopic column 2a and the slide column 2b, a fixing mechanism capable of fixing the telescopic length of the column 2 at a plurality of positions is provided. In the case of the present embodiment, the fixing mechanism is configured as a connecting tool 7 that connects and fixes the telescopic column 2a and the slide column 2b. For example, in the case of the present embodiment, the connector 7 is attached to the stopper holder 10 provided at the lower end of the telescopic pillar 2a, the lock plate 12 attached to one side surface of the slide pillar 2b, and penetrates the telescopic pillar 2a while being attached to the stopper holder 10. The lock plate 12 is composed of a telescopic stopper 11 having a lock pin 11c at the tip that engages with the lock plate 12, and the lock pin 11c at the tip of the telescopic stopper 11 is inserted into the hole 12a of the lock plate 12. And the lock pin 11c are engaged in the axial direction to move each other in the axial direction, and by extension, the support column is restrained from the axial movement (so-called expansion and contraction of the support column 2) between the telescopic column 2a and the slide column 2b to which they are attached. It has a structure that fixes the length of 2.

Although the detailed structure of the telescopic stopper 11 is not shown, for example, a boss plate that freely supports a knob portion 11a having a lock pin 11c at the tip and a shaft portion (not shown) of the knob portion 11a within a certain range. It is provided with 11b, and the lock pin 11c at the tip penetrating the telescopic column 2a and the hole 12a of the lock plate 12 can be taken in and out by grasping the knob portion 11a and moving it back and forth. In the case of the present embodiment, the boss plate 11b is arranged on the surface side of the stopper holder 10 and uses the fixed back plate 11e addressed to the inner surface of the telescopic pillar 2a to form the stopper holder 10 and the telescopic pillar 2a. It is fastened and fixed by a screw 11d so as to sandwich the. In the case of the present embodiment, the lock plate 12 is provided with a plurality of holes 12a, for example, eight holes 12a, and the lock pins 11c are selectively fitted into the holes 12a, so that the height position is set to eight stages. The structure is adjustable within the range of. That is, the awning of the present embodiment is at least a low position (a position shown by a virtual line in FIG. 6 or a position shown in (A) of FIG. 7) and a high position (a position shown by a solid line in FIG. 6 or (C) in FIG. 7). In addition to being able to expand and contract with the position shown in (1), the structure is such that the column length can be adjusted in a range of multiple stages, for example, 8 stages at a higher position. Further, the height adjustment of the support column 2 can be operated independently for each support column. Therefore, the height of the awning can be adjusted in 8 steps as needed, and the inclination of the girder due to non-landing can be adjusted by adjusting the height independently for each support.

The position and movement amount of the stroke end of the lock pin 11c at the tip of the telescopic stopper 11 penetrates the hole 12a of the lock plate 12 at the pushing position where the knob portion 11a is most pushed, but the bottom of the recess 13 It is a position where it does not abut (a position where it can pass through the recess 13 of the slide column 2b), and at the most pulled out position toward the front side, the lock pin 11c at the tip comes out from the hole 12a of the lock plate 12. Is set to. Therefore, it is sufficient to operate the telescopic stopper 11 only when the lock pin 11c at the tip is fitted into the hole 12a of the lock plate 12. In the case of the present embodiment, the lock plate 12 is connected to the slide column 2b by, for example, a screw 12c, but at the same time, a claw portion 12b formed by bending the upper end and the lower end is provided at the bottom of the recess 13 of the slide column 2b. It is positioned and locked at the same time by penetrating a hole (not shown).

On the other hand, the stopper holder 10 has a bottom portion of a double-cylinder structure including an outer portion 10a that surrounds the outside of the telescopic pillar 2a and an inner portion 10b that wraps around and surrounds the inside of the telescopic pillar 2a, and opens the lower end of the telescopic pillar 2a. It is fitted into the part. The inner peripheral surface of the inner peripheral portion 10b that wraps around the inside of the telescopic pillar 2a of the stopper holder 10 is in contact with the slide pillar 2b and has a structure that reduces friction and supports the stopper holder 10 so as to be smoothly slidable. Extending ridges 14 are appropriately formed on all surfaces. The inner portion of the stopper holder 10 including the ridge 14 also serves as a spacer for keeping the distance between the telescopic pillar 2a and the slide pillar 2b constant. Further, a ridge 14'protruding toward the inner side of the stopper holder 10 is also formed on the edge of the surface of the slide column 2b where the recess 13 is formed, and is sandwiched between the ridges 14 of the stopper holder 10. It is provided so as to prevent rattling in the horizontal direction orthogonal to the moving direction of the lock pin 11c. In the case of the present embodiment, the stopper holder 10 is fastened to the telescopic pillar 2a by a screw 11d when the boss plate 11b is attached to the surface side of the stopper holder 10.

The corner joint 5 straddles between the support column 2 and the girders 3 and 4 and between the girder 3 and the girder 4, and surrounds the corner where the support column 2 and the girders 3 and 4 are orthogonal to each other. By connecting three orthogonal surfaces (that is, plates 15) to the columns 2 and the girders 3 and 4, respectively, the columns 2 and the girders 3 and 4 are connected to each other. In the present embodiment, for example, as shown in FIG. 10, a plate 15 having a substantially triangular shape (in the present embodiment, it is a plate forming a deformed pentagon as if one corner of a rectangle is cut off, and has three corners and a hypotenuse. (Has) are butted and welded together. An L-shaped angle 16 is fixed to the inside of each of the three plates 15 of the corner joint 5 at intervals of substantially the same width as the support column 2 or the girders 3 and 4, for example, by plug welding, and the L-shaped angle 16 rises. The columns 2 or girders 3 and 4 can be installed in the space between the side (the side perpendicular to the fixed surface 15) and the surface of the other plate 15 facing the side (the side perpendicular to the fixed surface 15). Two planes that are orthogonal to each other, that is, two plates 15, and two sides that are parallel to the above-mentioned two planes of the L-shaped angle 16 provided therein are the pillar 2 or the four sides of the girder (that is, the pillar 2 or the girders 3, 4). The function of guide and positioning is exerted by abutting the two surfaces orthogonal to each other and a part of the two surfaces facing each other and sandwiching the support column 2 or the girders 3 and 4. The L-shaped angle 16 has an L-shaped cross section and also has an L-shaped plan view, and also functions as a reinforcing material for each plate 15. The shape of the corner joint 5 is not limited to the shape shown in the drawing, and the support 2 and the girders 3, 4 or the girder 3 are formed at positions away from the positions where the three planes orthogonal to each other, the support 2 and the girder are abutted. The shape is not limited to a specific shape as long as it has a hypotenuse portion interlinking with the girder 4.

Further, since the paragola type awning of the present embodiment connects the girders 3 and 4 via the corner joints 5 arranged so as to cover the upper ends of the columns 2, the upper end openings of the columns 2 are covered by the corner joints 5. .. Further, since the girders 3 and 4 are also connected by pressing the openings at both ends against the support column 2 at the same time, the openings are closed by the support column 2 and further covered by the corner joint 5. Therefore, the corner joint 5 functions as a cap for both the support column 2 and the girders 3 and 4.

8 and 9 show cross sections of the girders 3 and 4. Since it is sufficient for the side girder 3 to function as a simple structure, it is composed of, for example, a simple square cylinder. On the other hand, the rail girder 4 is composed of, for example, a square cylinder, and a rail portion 22 for accommodating and guiding the guide roller 25 is provided in one corner thereof, for example, the lower corner. The rail portion 22 is provided with a groove in the center for passing the hang stay 26, and is formed on both sides thereof with a bottom surface that functions as a guide rail for receiving and supporting the guide roller 25.

The rail portion 22 may be formed integrally with the rail girder 4, that is, as one square cylinder, or may be a separate body. However, in the case of the present embodiment, the girder 4 and the rail portion 22 are simultaneously formed by, for example, extrusion molding. It is formed. Of course, the separately molded girder 4 and the rail portion 22 may be integrated by fixing means such as welding or riveting. Of the rail girder 4, the portion that functions as a girder is brought into contact with the strut 2, but the end of the rail portion 22 is provided with a gap (guide roller inlet) between the rail girder 4 and the strut 2 to provide a awning sheet 6. The guide roller 25 may be provided so that it can be incorporated after the skeleton 1 is assembled. Further, in the case of the present embodiment, the rail portion 22 is arranged so as to open downward and is provided to support the roller charged from the opening, but the present invention is not limited to this, and the rail portion 22 may be provided in some cases. May be opened on the side (inner surface) of the girder.

An L-shaped female screw plate 19 having a female screw (not shown) is installed in a portion where the fastening bolt 18 is fastened to the rail girder 4, the side girder 3, and the corner joint 5 of the support column 2. Since the female screw plate 19 also functions as a reinforcing metal fitting, it is preferable that the female screw plate 19 is previously fixed to the inside of each open end of the rail girder 4, the side girder 3, and the support column 2 by welding or the like.

Further, in the above description, the opening of the rail portion 22 of the rail girder 4 is arranged downward so that the awning frame 20 is suspended under the rail girder 4, but in some cases, it may be on the side of the rail girder 4. An opening may be arranged to support the awning frame 20 at the same height as the rail girder 4 or at a position higher than the rail girder 4. By raising the support position of the awning frame 20, the height of the awning sheet 6 can be raised.

At the lower end of the support column 2, a load receiving portion 8 that protrudes laterally from the support column 2 and receives the weight 9 is provided. The load receiving portion 8 of the present embodiment is, for example, a disk, and is fixed to the lower portion of the support column 2, that is, the lower end of the square tube portion (not shown) built in the slide column 2b by welding, for example. Then, by inserting a square tube portion (not shown) from the lower end opening of the slide column 2b and fixing it to the side surface of the slide column 2b with a fastening bolt (not shown) or the like, the load receiving portion 8 is attached to the lower end of the slide column 2b, that is, the column. It is prepared at the lower end of 2. The support column 2 is fixed by placing the weight 9 on the load receiving portion 8. Here, the load receiving portion 8 not only has a function of mounting the weight 9 but also has a function of widening the installation area of the support column 2 to prevent it from falling over. On the other hand, if the load receiving portion 8 is too large, it hinders the tilting of the support column 2, so it is preferable to make the load receiving portion 8 the minimum size necessary for receiving the weight 9. In the present embodiment, the disk is used, but it may be a square plate, a triangular plate, or a polygonal plate.

The weight 9 is, for example, a half-split ring as shown in FIG. 14, and one ring (weight assembly) is formed by combining the half-split rings so as to surround the support column 2, and the weight 9 is further stacked on the weight 9 to form FIG. It is configured in a cylindrical shape as shown in. The half-split ring-shaped weight 9 is formed with irregularities 9a and 9b that fit with the mating half-split ring at both ends in the circumferential direction. That is, a convex portion 9b is formed on one end surface of the semi-cylindrical weight 9 in the circumferential direction, and a concave portion 9a into which the convex portion 9b is fitted is formed on the opposite end surface, and the other weight 9 is formed. It is provided so as to form a ring in combination with the unevenness 9a and 9b of. The concave portion 9a and the convex portion 9b of the present embodiment have a curved surface having the same curvature as the weight 9 itself, and are configured to mesh with each other only by sliding them in the vertical direction and combining them. That is, the pair of semicircular weights 9 can be fitted and removed in the vertical direction, but not in the horizontal direction. That is, it is prevented from coming off in the horizontal direction.

On the other hand, the weight 9 is provided with, for example, a step 9g in which the upper half portion 9c and the lower half portion 9d are displaced in the radial direction to form a space in which the upper half portion 9c fits inside the lower half portion 9d. , The weights 9 are provided so as to prevent radial movement (in other words, horizontal direction) between the upper and lower weights 9 when the weights 9 are stacked. Further, while the protrusion 9f is provided on the bottom surface of the upper half portion 9c, a recess 9e that penetrates the upper half portion 9c in the axial direction is formed. Then, when stacking a plurality of sets of weights 9, the recesses 9e and the protrusions 9f are combined to prevent the weights 9 from rotating in the circumferential direction.

In the case of the present embodiment, the weights 9 are made of cast iron, and are provided so as to weigh 10 kg on one side and 20 kg on a pair, for example. The weight of the weight 9 is adjusted by increasing or decreasing the number of stages of the weight assembly to be stacked. Of course, the weight 9 is not limited to the above-mentioned cast iron, but may be made of concrete or a plastic container that is made into a weight by injecting water or the like, and the shape is not limited to the half ring shape. It may be a block of shape or U shape.

On the other hand, in the case of the present embodiment, the awning sheet 6 constitutes one large awning sheet 6 by connecting a plurality of small sheet-shaped members 21 with the awning frame 20. Specifically, in the present embodiment, a plurality of awning frames 20 movably supported along the rail girder 4 by the sliding means 24, and a plurality of sheet-like members 21 stretched between the awning frames 20. Therefore, one awning sheet 6 is configured.

The awning frame 20 is a so-called bone that connects a plurality of strip-shaped sheet-shaped members 21, and in the present embodiment, for example, a pipe made of an extruded aluminum material having a cross-sectional shape as shown in FIG. 9 is used. The awning frame 20 is composed of a square cylinder portion 20a and a seat locking portion 20b, and the seat locking portion 20b is integrally formed under the square cylinder portion 20a. For example, two C-shaped long grooves 20c are provided on the bottom surface of the seat locking portion 20b. The cross-sectional shape of each elongated groove 20c has an opening portion narrower than that of the back portion. The square tube portion 20a and the seat locking portion 20b are provided over the entire length of the awning frame 20. The awning frame 20 having such a cross-sectional shape is formed by, for example, extrusion molding. The openings at both ends of the awning frame 20 are closed by side plates (not shown). The connecting structure between the awning frame 20 and the sheet-shaped member 21 is not particularly limited to the above-mentioned method, and other connecting means such as a fastener can also be applied.

The sheet-shaped member 21 stretched between the awning frames 20 is not limited to a specific material, but it is preferable to use a canvas material using, for example, high-strength polyester or recycled polyethylene. In the case of the present embodiment, a plurality of strip-shaped sheet-like members 21 are attached to a plurality of awning frames 20 and connected to each other to form one large awning sheet 6. In the case of the present embodiment, the sheet-shaped member 21 has the same length in the front-rear direction (length in the lateral direction along the rail girder), and the distance between the awning frames 20 when the awning sheet 6 is opened is the same. However, depending on the case, the lengths of some or all of the sheet-shaped members 21 may be different.

The front end portion and the rear end portion of the sheet-shaped member 21 are each provided with a tubular portion through which the mandrel 23 is passed, and the tubular portion inflated by passing the mandrel 23 is respectively provided in each elongated groove 20c of the awning frame 20 from the end. By inserting and pulling out from the opening portion in the longitudinal direction of each elongated groove 20c, it is connected to the front and rear awning frames 20, respectively. That is, the front and rear awning frames 20 are connected by the sheet-shaped member 21. The sheet-shaped member 21 is attached to the awning frame 20 by inserting the tubular portion through the opening at the end of each elongated groove 20c of the awning frame 20 and inserting the sheet-shaped member 21 through the opening portion of the elongated groove 20c. As a result, the core rod 23 passed through the tubular portion is hooked in the narrow opening of the long groove 20c to prevent the sheet-shaped member 21 from coming off. Incidentally, in the present embodiment, the length of each awning frame 20 and the width of each sheet-like member 21 are substantially the same as the length of the front and rear girder frames 3, and the awning sheet 6 is substantially the same as the skeleton 1 in the fully open state. It is provided so that it has the same size, but it is not particularly limited to this.

As the sliding means 24, for example, in the case of the present embodiment, a twin-wheel guide roller 25 that rolls on the guide rail 22, a hang stay 26 to which the roller 25 is rotatably attached, and an end portion of the awning frame 20 are suspended. It is composed of a hanging tool 27 and a connecting tool having a variable angle for connecting the hanging tool 27 and the hanging tool 27 so as to be swingable, for example, a cannabis hook 28. The upper end of each hanging tool 27 is attached to the hang stay 26 by a cannabis hook 28, but the present invention is not particularly limited, and the hanging tool 27 and the hang stay 26 may be directly connected. By rolling each roller 25 on the bottom surface (guide rail) of the rail portion 22, the awning frame 20 can be moved along the guide rail 22, that is, the rail girder 4. The guide roller 25 at the head of the present embodiment is provided with two sets of rollers 25 for stability, but the guide roller 25 is not limited to this.

In the case of the present embodiment, the hanging tool 27 fixed to both ends of the awning frame 20 and the hang stay 26 of the guide roller 25 charged in the rail portion 22 of the rail girder 4 are a connecting tool having a variable angle, for example, a carabiner. It is hung via a hook 28 or the like. In this case, the guide roller can be easily removed from the awning frame 20 simply by opening the gate of the cannabis hook 28. Of course, in this embodiment, the cannabis hook 28 is adopted, but it is not particularly limited to this, and it goes without saying that something like a hanging string may be used. Further, in the present embodiment, the hanging tool 27 uses a plate, but the present invention is not limited to this, and a chain (not shown) or the like may be interposed.

Further, in the vicinity of the inlet of the guide roller 25 of the rail girder 4, a guide roller loaded into the guide rail by applying a load to the guide roller 25 by spring elasticity when the guide roller 25 passes is on the inlet side. A slider stopper 29 for preventing the product from falling back is provided. The slider stopper 29 is made of, for example, a leaf spring, and is provided so as to exert spring elasticity and urge the roller when the roller passes by being screwed to the ceiling surface of the rail portion.

On the other hand, the awning frame (hereinafter referred to as the fixed awning frame 20') arranged on the innermost side of the rail girder 4 (opposite the entrance) has a stay 31 to which the hanging tool 27 is attached to the rail girder 4. The fastening means is fixed and suspended by, for example, a knob bolt 30. As a result, when the first awning frame is pulled out to the entrance side, the last awning frame 20 is fixed, so that the awning sheet 6 is deployed.

In the present embodiment, the hanging metal fitting for suspending the awning frame 20 is stretched substantially flat with a slight inclination as a whole by making the left and right support heights different by setting the other end side longer than the one end side. It is said to be a structure. Of course, the left and right support heights of the awning sheet 6 can be aligned and stretched horizontally. Here, "tensioning" the sheet-shaped member 21 includes not only the case where the sheet-shaped member 21 is taut without slack, but also the case where the sheet-shaped member 21 is loosened to some extent.

According to the paragola type awning configured as described above, the support column 2, the side girder 3 and the rail girder 4 are connected to each other by using the corner joint 5 and can be easily assembled. In particular, in the case of the present embodiment, the column 2 and the side girders 3 and 4 are inserted into the space (so-called recess) between each plate 15 of the corner joint 5 and the L-shaped angle 16 and abutted with each other to form the corner joint 5. By simply passing the fastening bolt 18 through the hole 17 from the outside and tightening it to the support column 2 and the side girders 3 and 4, the corner joint 5 and the support column 2 and the side girders 3 and 4 are fastened to complete the assembly of the frame 1.

That is, the skeleton 1 is assembled by inserting the columns 2 and the girders 3 and 4 into the corner joints 5 from three directions and fixing them to the two orthogonal surfaces of the corner joints 5 with bolts. For example, first, the upper end opening of the support column 2 is covered with the corner joint 5, and then bolted on two sides to fix the corner joint 5 to the support column 2. After that, the support column 2 is inserted into the corner joint 5 and pushed in until it hits the opposite surface (ceiling surface), or is pushed in until the hole 17 and the screw hole (not shown) of the support column 2 meet, and the hole is made in the corner joint 5. The fastening bolt 18 is screwed in from 17, and the corner joint 5 is connected to the support column 2.

Next, insert either or both of the side girder 3 and the rail girder 4 so as to abut against the side surface of the support column 2, and then bolt them on the two sides to either the rail girder 4 or the side girder 3. The corner joint 5 is fixed to one or both of them. By repeating this, two sets of portal frames are constructed. After that, the girders remaining in the vacant corners of each corner joint 5 are inserted so as to connect the two sets of gate-shaped frames, and the girders are abutted against the support columns 2 and then fixed to the corner joints 5 with fastening bolts. Assemble skeleton 1. At this time, it is preferable that the skeleton 1 is assembled at a low position where the support column 2 is contracted, that is, with the support column 2 shortened. For example, it is preferable to assemble at a height of about 1800 mm so that the operator can work in a standing posture in order to carry out the assembly safely.

In the above-described embodiment, two sets of gate-shaped frames are first assembled, and then the remaining girders, for example, rail girders 4, are connected to the corner joints 5 between them to complete the frame assembly. However, the present invention is not particularly limited to this, and the support column 2, the rail girder 4, and the side girder 3 may be connected at the same time.

Next, it is preferable to assemble the awning sheet 6 to the rail girder 4 while keeping the support column 2 in the contracted low position. For example, since the guide roller 25 can be attached to the side of the awning sheet 6 in advance when leaving the factory, the entrance at the end of the rail girder 4 (the gap between the rail portion 22 of the rail girder 4 and the column 2). The awning sheet 6 can be quickly and extremely easily attached by simply mounting the guide roller 25 into the rail portion 22. At this time, the fixed awning frame 20'arranged on the innermost side of the rail girder (opposite the loading entrance) is attached to the outside of the rail girder 4 with a knob bolt 30 and suspended without being inserted into the rail portion 22. Lower. In the present embodiment, the awning sheet 6 is attached by inserting the guide roller 25 into the rail girder 4 after assembling the skeleton 1, but the present invention is not particularly limited to this, and for example, the factory has passed in advance. Sometimes, when the guide roller 25 is set on the rail portion 22 of the rail girder 4, the carabiner hook 28 is attached to the hang stay 26 of the guide roller 25 of the rail girder 4 at both ends of the awning frame 20. It can also be installed with a single touch.

According to the awning of the present embodiment, the awning sheet 6 can be easily and easily attached to the skeleton 1 and the awning sheet 6 can be removed from the skeleton 1, so that the maintenance work associated with the awning sheet 6 can be reduced. The awning sheet 6 can be easily selected and replaced according to the usage situation, and the convenience and versatility of the awning can be improved.

Then, after the assembly of the awning sheet 6 to the rail girder 4 is completed, the support column 2 is extended and raised to assemble a paragola having a predetermined height. Here, four columns 2 may be extended at the same time, but as shown in FIGS. 7 (A) to 7 (C), by extending each side to raise the height, it is easy to extend 2 without using a stepladder or the like. A paragola of a predetermined height is assembled by a person. The corner joint 5 has a structure in which three planes orthogonal to each other are closed, and the strut 2 and the girders 3 and 4 are in phase with each other straddling between the strut 2 and the girders 3 and 4 and between the girder 3 and the girder 4. Since it surrounds the orthogonal corners, it functions even if it is a brace and has high rigidity. Therefore, even if the support column 2 is tilted, the corner joint 5 does not buckle or the angle between the frames does not change, so that the support column 2 can be extended one by one to tilt the frame as a whole. Also, when dismantling, the struts 2 on one side are shrunk with the skeleton 1 tilted as a whole, the struts 2 on one side are lowered to the ground, and then the struts on the other side are lifted and tilted to shrink the struts. You can easily lower the awning to a lower position. Then, the skeleton 1 can be easily and quickly disassembled on the ground simply by removing the awning sheet at a low position and further removing the bolts of the corner joint 5.

The worker can perform all the work on the ground while standing, that is, assembling the skeleton 1, attaching the awning sheet 6 to the skeleton 1, etc. without using a stepladder, and finally extending and lifting the support column 2. The pergola-type awning can be assembled easily, safely and quickly. Further, in the dismantling, all the work can be performed on the ground after the support column 2 is shrunk, so that the dismantling can be easily performed in a short time. Moreover, assembling to some extent, for example, attaching a hanging bracket with a guide roller to the awning sheet 6 and welding can be completed at the time of shipment from the factory, so that the work at the site can be reduced to the extent of bolt tightening, so that the total is further increased. Time can be shortened. For example, the assembly can be completed by two workers in about 20 minutes, that is, about 1/5 to 1/6 of the conventional paragola.

Here, in the installation of the awning, it is required to install the girders 3 and 4 on the support column 2 horizontally. The girders 3 and 4 need to be horizontal not only in terms of appearance but also in order to smoothly open and close the awning sheet 6 which can be opened and closed. However, the place where a simple awning is required is not always a flat and level place. In the present specification, the "horizontal" of the digits 3 and 4 obtained by adjusting the height of the support column 2 is not limited to horizontal in a strict sense, but also includes "approximately horizontal" and "almost horizontal". It is used to mean substantially horizontal to include.

In this way, when there is unevenness in the place where the awning is required to be installed, it is necessary to secure the horizontality of the girders 3 and 4 by adjusting the height of each of the columns 2. The lock plate 12 is provided with a plurality of holes 12a, for example, in the case of the present embodiment, eight holes 12a, and the lock pin 11c is selectively fitted into the holes 12a to obtain a height at a high position. The structure is such that the position can be adjusted in a range of 8 steps. That is, in the awning of the present embodiment, the awning height can be adjusted in eight stages as needed. Further, since the height adjustment of the support column 2 can be operated independently for each support column 2, the height can be adjusted for each support column 2 as needed. For example, the support column 2 may be extended so that it touches the ground when the ground is low and floating, or the support column 2 may be shortened so that it cannot be pushed up when the ground is high. Even when the flatness of the ground at the place where the support is installed is not obtained by adjusting the height every 2 (horizontal slope, etc.), it is possible to eliminate the rattling and inclination of the entire frame 1. Then, the awning height can be set to a desired height, and the awnings can be installed by maintaining the upper girders 3 and 4 of the support column 2 horizontally. Note that FIG. 12 shows an embodiment in which eight holes 12a are provided at intervals of 15 mm so that a total of 105 mm can be adjusted, but this is just an example and is not shown, for example. Six holes may be provided at intervals of 20 mm so that a total of 100 mm can be adjusted.

Further, since the corner joint 5 also functions as a cap that covers the connecting portion between the opening at the top of the column and the girder, it is possible to prevent rainwater and the like from entering and to have a simple structure that does not require a retrofit cap. As well as reducing the number of parts, the assembly process and disassembly process can also be reduced.

Moreover, since all the work can be performed on a flat ground without using a stepladder, there is no risk of falling from the stepladder and it is safe. The awning sheet 6 can be easily attached and detached without the need for special tools. Moreover, since the support column is simply fixed by placing the weight 9, there is no need for large-scale construction such as foundation work. Therefore, it enables simple and quick assembly and disassembly, and is ideal for temporary simple installation.

The above-described embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be performed without departing from the gist of the present invention. For example, the awning according to the above embodiment is effective when applied to a temporarily installed awning, but this does not mean that it cannot be applied to a permanently installed awning. For example, even when the support 2 is embedded in the ground or the stationary foundation method of fixing with anchor bolts is adopted and applied to a permanent awning, the height of each support 2 is adjusted to flatten the ground at the place where the support is installed. Even when the degree is not high (horizontal slope, etc.), it is possible to eliminate the rattling and tilting of the entire frame 1. Therefore, the advantage that the awning can be installed by simplifying the ground leveling and foundation preparation before the awning is installed and the advantage that the assembly time can be significantly shortened are not lost.

Further, the awning of the present invention is not limited to the paragola type in which the canvas 6 is stretched substantially flat as shown in FIGS. 1 to 6, and the support columns 2 and the girder 3 as shown in FIGS. 16 and 17 are used. It is also possible to attach the dome-shaped frame 32 on the skeleton 1 of the above and apply the canvas 6 to the dome-shaped awning. In the dome-shaped frame 32, the tip of the canvas support frame 34 radiating from the central hub 33 is supported by the frame fixing bracket 35 detachably attached to the corner joint 5 of the support column 2, while the support column 2 of the canvas support frame 34 is supported. The canvas 6 is stretched in a dome shape by being supported from below by an auxiliary frame 36 attached to the side surface of the support column 2 in the vicinity. The auxiliary frame 36 is detachably attached to the support column 2 by an auxiliary frame support metal fitting 37 provided on the side surface of the support column 2. Even in this case, after assembling the skeleton 1 and attaching the canvas 6 at a low position, if the support columns 2 are extended one side at a time or all at once and lifted to a high position, the skeleton 1 can be assembled on a stepladder. Unlike the conventional awning that had to be attached to the canvas or the canvas, the advantage of being able to significantly reduce the assembly time is not lost. The dome-shaped canvas 6 is covered over the dome-shaped frame 32 arranged diagonally of the girder 3 assembled in a rectangular shape, and the lower end edge of each side is wrapped around the girder before the surface fastener or the surface fastener. It is fixed with a hook or the like. Further, in the middle of the canvas 6, for example, the dome-shaped frame 32 is fixed with a string or a band.

Further, FIGS. 18 to 21 show other embodiments. The awning of this embodiment is a method of fixing the awning sheet 6 in a closed state in which the awning sheet 6 is expanded (a state in which the space surrounded by the girders 3 and 4 is closed by the awning sheet 6). It is a different one. That is, the awning frame 20 arranged at both ends of the front end and the rear end of the awning sheet 6 and the locking member 38 provided at the center of the fixed awning frame 20'in the width direction are hooked on the hook 39 suspended from the side girder 3. As a result, the structure is such that the end of the awning sheet 6 is fixed. The locking member 38 is attached to the awning frame 20 and the fixed awning frame 20'via, for example, a clip 41. One end of the clip 41 is provided with a cylindrical fixing portion 45 fitted into the C-shaped long groove 20c at the bottom of the awning frames 20 and 20', and is held and fixed by the elastic force of the C-shaped long groove 20c. .. Further, the clip 41 is passed through the two belt loops 46 arranged in parallel with the locking member 38 so as to be folded back to hold the locking member 38. On the free end side of the locking member 38, a hole 42 through which the tip 39a of the hook 39 penetrates and a ring portion 43 for gripping are provided. Here, since the locking portion 38 provided in the fixed awning frame 20'is usually fixed in position after being set on the rail girder 4 of the awning sheet 6, it is prevented from coming off after passing the tip 39a of the hook 39 through 42. For example, a carabiner hook 40 is hooked on the hole 44 and hung. Of course, the member for preventing the removal is not limited to the carabiner hook 40, and pins and the like may be used. In the open state in which the awning sheet 6 is stored (most of the space surrounded by the girders 3 and 4 is open), the guide roller 25 of the awning frame 20 of the awning sheet 6 is a plate inside the rail girder 4. It is stopped so that the return is prevented by overcoming the spring (not shown).

According to the method for fixing the awning sheet 6 described above, the awning sheet 6 can be pulled out by hooking the hook at the tip of the operating rod 47 on the ring portion 43 of the fixing member 38 attached to the awning frame 20 at the tip. The awning sheet 6 can be deployed. Then, in the case of deploying on the entire surface, the awning frame 20 on the tip side can be passed through the side girder simply by pulling the fixing member 38, hooking the hole 42 of the fixing member 38 on the hook 39 of the side girder 3 and penetrating the tip portion 39a. It can be fixed to 3. The operation rod 47 is attached to and stored in the upper support column of the support column 2 via a hook or the like.

Further, in the above-described embodiment, an example of application to a quadrangular paragola type awning in which four columns 2 and two girders 3 and 4 are combined has been mainly described. The number of awnings and the shape of the awning are not particularly limited, and awnings with three struts (for example, Japanese Patent Application Laid-Open No. 2019-49161), awnings with five struts, or more awnings can be used. Further, the shape of the awning may be polygonal or circular, as long as it has a sheet that can be opened and closed. If the frame structure is other than a rectangle, the angle between the support column and the girder connected to it will be less than 90 ° or more than 90 °. Therefore, when the corner joint 5 is used, the support column 2 and its connection (In this case, one girder is not limited to the structure like the rail girder described above, and may be a mere girder material) between the two girders 3 and 4 and the girder. Three intersecting surfaces (that is, plates 15) are provided on the columns 2 and the girders 3 and 4, respectively, so as to surround the corner where the columns 2 and the girders 3 and 4 intersect between the columns 3 and the girder 4. By connecting the columns 2, the columns 2 and the girders 3 and 4 may be connected to each other, but the columns 2 and the girders 3 and 4 may be directly connected without using the corner joint 5.

Further, in the above-described embodiment, a plurality of strip-shaped sheet-shaped members 21 are attached to a plurality of hanging frames and connected to each other to form one large awning sheet 6, but the present invention is particularly limited. In some cases, the canvas may be hung with a string at the four corners or in the middle of the frame like a tarp, or it may be used simply by covering the frame with a twist.

Further, in the case of the above-described embodiment, the L-shaped angle 16 and the corner joint 5 are permanently fixed by welding such as plug welding or spot welding, but the present invention is not particularly limited to this. By arranging the L-shaped angle-shaped structure so as to move forward and backward toward the two opposing surfaces, that is, the two plates 15, each surface 15 of the fixed corner joint 5 and the movable L-shaped angle are arranged. The support and the positioning function may be exerted by sandwiching the support column 2 or the girders 3 and 4 between the shaped structure.

Further, the support column 2 in the above-described embodiment has a structure in which the support column 2 can be expanded and contracted between at least a low position and a high position, and the height position can be adjusted in a range of a plurality of stages, for example, eight stages at least at a high position. However, the structure is not particularly limited to this, and the height position may be adjusted stepwise or continuously at an arbitrary position in order to adjust the non-landing condition. That is, the support column 2 is not expanded and contracted between the height position suitable for assembling the skeleton 1 and mounting the awning sheet 6 and the height position suitable for using the awning, but from the ground unevenness. It may be possible to adjust the strut height only to keep the girder horizontal.

Further, the support column 2 in the above-described embodiment adopts a telescopic structure and can be expanded and contracted, but the present invention is not particularly limited to this, and other expansion and contraction structures such as an expansion and contraction ladder, a lattice structure (diamond lattice), and a fluid pressure cylinder. , A bellows structure or the like may be used. Alternatively, it may have a telescopic structure in which a pair of chains that bend only on one side are arranged line-symmetrically, wound up, and sent out facing each other so as to bend inward so that they do not bend each other and extend as columns.

Further, the column 2 in the above-described embodiment is composed of two members, an upper column (expandable column 2a) and a lower column (slide column 2b), but the present invention is not particularly limited to this, and three or more columns are not particularly limited. The telescopic structure may be formed at two or more places by two or more sets of connecting tools 7 provided at two or more joint points as well as being made of a column member.

Further, as a fixing mechanism capable of fixing the expansion / contraction length of the support column 2 at a plurality of positions, in the above-described embodiment, it is configured as a connecting tool 7 for fitting the lock pin 11c and the hole 12a. Not necessarily limited to the mating structure. For example, a braking mechanism may be used in which the screw tips of the screw pairs provided on the telescopic column 2a side are pressed against the surface of the slide column 2b to be fixed by friction, or as a structure in which irregularities are fitted and locked. Is also good. It is possible to restrain the expansion and contraction of the telescopic pipe by fitting it into the recess of the mating member and engaging it. The convex member and the concave member may be hemispherical or have a rectangular cross section.

Further, a restraint mechanism may be used in which braking is applied to one of the column members that move linearly. For example, a restraint mechanism consisting of a combination of a rod having a saw blade-shaped uneven surface and a claw that meshes with the uneven surface of the rod to stop the movement of the rod may be applied. In the case of a combination of a saw blade-shaped uneven surface and a claw, the saw blade-shaped uneven surface becomes a slope when the claw moves relatively upward, giving a force to retract the claw and relatively downward. When the claw moves toward it, the part that becomes a horizontal surface engages with the claw and functions as a stopper to prevent its descent, so it is only necessary to constantly urge the claw toward the rod with a spring or the like. It can be moved by simply pushing up the slide pillar 2b side without moving it in and out, and when the hand is released, the uneven surface and the claw automatically move to the engaged state, and the movement in the height direction is fixed. can do. As a releasing mechanism for releasing this fixed state, for example, a knob connected to the claw may be provided, and the claw may be separated from the uneven surface of the rod by pulling the knob. Although not shown, a spring structure such as a leaf spring or a compression coil spring is interposed between the telescopic column 2a and the claw, and the claw is usually an uneven surface due to the spring force of the spring structure. It may be provided so as to be urged toward. Then, when the knob is pulled, the claw may be provided so as to retract from the uneven surface.

Further, as a fixing mechanism capable of fixing the expansion / contraction length of the support column 2 at a plurality of positions, the rack may be moved up and down by the rotation of the gear by combining the rack and the pinion. In this case, by interposing a combination of a worm gear and a worm wheel in the gear train to provide self-locking property, the support may be used as a contraction prevention mechanism. In this case, a complete reverse rotation prevention mechanism may be configured in combination with another braking mechanism. Since the height can be changed continuously, fine adjustment is easy.
