Description

[Technical Field]

[0001] This invention relates to a sunshade (sunshading device) used to block sunlight entering a building through openings such as windows and doors installed in the wall of a building. More specifically, it relates to a sunshade that can be installed safely, easily, and efficiently in a space-saving manner, without damaging the building's wall, etc., and that blocks sunlight entering the building, and can also be used as an indoor partition (divider). [Background technology]

[0002] In recent years, sunshades have been installed in gardens, verandas, and other areas facing windows and doors to block sunlight from entering buildings. These sunshades are hung by attaching their upper edge to a mounting bracket such as a hook attached to the eaves or wall, and are installed and fixed in a curved shape from the eaves. In other words, the lower edge of the sunshade is attached to a weight such as a water tank or sandbag placed on the ground via a connector such as string, so that it extends diagonally outward as it goes downward without sagging.

[0003] However, with conventional sunshades, attaching the mounting brackets to a building or attaching the upper edge of the sunshade to the mounting brackets requires working at height using climbing devices such as stepladders, stools, or ladders, making installation dangerous. Moreover, when drilling holes under the eaves or in the wall to attach the mounting brackets, it is costly to restore the original condition in rental properties, making people hesitant to install sunshades. In addition, installing and securing a sunshade requires the hassle of having to prepare many separate parts, such as mounting brackets, a water tank (weight), and strings (connectors).

[0004] Furthermore, because conventional sunshades are stretched diagonally from the eaves or wall outwards towards the outside of the building, they are installed and fixed so that their lower edges extend into the garden, balcony, etc., requiring a corresponding amount of space (installation area). Moreover, installing a sunshade reduces the usable area of ​​the garden, balcony, etc., and there is a risk that children or people walking by at night may not notice the string (connector) used to secure the lower edge, and get their feet caught in the string and fall.

[0005] Therefore, several mechanisms have been proposed for installing sunshades without attaching mounting brackets to the eaves or wall. For example, an awning has been proposed in which a pair of supports are erected in a tensioned manner between an installation surface such as the top surface of the eaves of a building and the floor, and the sheet material is wound or unwound around a rotatable core material (roll) that is hung horizontally between the supports (see Patent Document 1 and Patent Document 2). Also proposed is a pole support device that includes a curtain cloth stretched and supported by a plurality of poles that are leaned diagonally against the wall surface of a building (see Patent Document 3).

[0006] However, even in the systems disclosed in the above-mentioned Patent Documents 1 to 3, the sunshade fabric is stretched and supported at an angle so that it spreads out from the eaves or wall toward the outside of the building. Therefore, if there is not enough space outside the building for installation, it is currently necessary to give up on installing a sunshade. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Registered Utility Model No. 3168864 [Patent Document 2] Registered Utility Model No. 3212101 [Patent Document 3] Registered Utility Model No. 3184002 Summary of the Invention [Problem to be solved by the invention]

[0008] This invention was made in consideration of the above-mentioned conventional circumstances, and aims to provide a technology that can install a curtain cloth that blocks sunlight from entering a building in a space-saving, safe, simple and efficient manner without damaging the building's walls, etc., and that can also be used as an indoor partition (divider). [Means for solving the problem]

[0009] The sunshade of the present invention is composed of a pair of support poles that are simply erected in a space, both of which have support surfaces that abut on one side in the axial direction and the other, and a curtain cloth that is stretched and supported by the support poles to block sunlight that enters the building, and each of the support poles has a holder to which the curtain cloth is attached and is erected vertically in the space.

[0010] In this sunshade, the support pole can be adjusted to expand and contract in the axial direction and can be provided with an expansion / contraction adjusting means having a tension structure that is biased in the axial direction to expand. In addition, this support pillar can be made up of a plurality of fitted poles, and can be provided with a pressure-type extension / contraction adjustment means that allows the sliding positions of the poles to be adjusted and fixed by pressing the outer periphery of the pole located inside against the outer periphery of the pole due to the inclination of a crimped annular body arranged on the outer periphery of the pole.

[0011] The support strut has a first pole, a second pole that can be fitted into the first pole, and a telescopic adjustment means to which the upper end of the first pole is attached, which connects and fixes the second pole and releases it, making the second pole adjustable in extension and retraction relative to the first pole. The telescopic adjustment means comprises a telescopic adjustment body main body having a hollow cylindrical upper cylinder into which the lower end of the second pole is fitted, and a hollow cylindrical lower cylinder that is integrally connected to the lower part of the upper cylinder, to which the upper end of the first pole is attached from below and whose upper end located within the upper cylinder has an inclined portion; a slide operation body receiving portion provided in the lengthwise direction of the telescopic adjustment body main body from the outer wall portion of the upper cylinder to the outer wall portion of the lower cylinder; a slide operation body attached to the slide operation body receiving portion so as to be slidable in the lengthwise direction of the telescopic adjustment body main body and having an operation protrusion on its inward protruding end; and a slide operation body inside the upper cylinder, whose inner periphery is in contact with the outer periphery of the second pole on the inclined portion of the lower cylinder. a guide cylinder that is integrated with the crimped annular body that is disposed on the outer periphery of the second pole on the crimped annular body and has an operation protrusion of the slide operation body connected to its outer periphery; and an annular elastic body that is disposed between the upper side step portion of the upper cylinder and the crimped annular body and that applies elastic force to the crimped annular body, the guide cylinder, and the slide operation body toward the lower cylinder; and when the slide operation body is slid toward the upper cylinder, the operation protrusion pushes up the crimped annular body and the guide cylinder via the operation protrusion against the elastic force of the annular elastic body, bringing the crimped annular body into a horizontal state and eliminating the protrusion of the inner periphery of the crimped annular body toward the outer periphery of the second pole, bringing the second pole into a connected and fixed released state that can be adjusted for extension and contraction; and when the slide operation body is restored to its original position by the elastic force of the annular elastic body, the crimped annular body returns to its inclined state and the inner periphery of the crimped annular body is crimped and crimped to the outer periphery of the second pole, bringing the second pole into a connected and fixed state.

[0012] In the sunshade according to the present invention, the holder may be an annular body fitted onto the outer periphery of the support pole. The holder preferably also includes a fastening screw for attaching the screen cloth and securing it to the support pole.

[0013] In the sunshade according to the present invention, it is preferable that the support pole further includes a ring for positioning the holder. In the sunshade of the present invention, the support pole preferably has a fixed plate at each of its axial ends, which abuts against the support surface of the space, and the fixed plate preferably has a trumpet shape that expands toward the abutting surface.

[0014] In addition, in the sunshade according to the present invention, the support pole may further include a connecting pole that can be connected to an end of the second pole. Furthermore, in the sunshade according to the present invention, the screen cloth may be integrally formed from a flexible member having breathability. [Effects of the Invention]

[0015] According to the invention described in claim 1, it is possible to install a sunshade that blocks sunlight from entering a building in a space-saving, safe, simple, and efficient manner without damaging the building's walls. In other words, because the sunshade is attached to vertical support poles, it can be installed in a very small space (area) required to erect the support poles, maximizing the use of the garden or balcony area. Moreover, because the distance between the pair of erect support poles can be freely adjusted with a high degree of freedom, the sunshade can be installed appropriately depending on the width of the sunshade, and it can also be used as an indoor partition. Furthermore, as long as there is a solid ceiling surface such as under the eaves and a floor surface, the sunshade can be installed safely, easily, and efficiently without drilling holes in the walls or under the eaves of the building. Furthermore, in order to install and secure the sunshade, it is not necessary to prepare many parts such as mounting brackets, a water tank (weight), and strings (connectors), but rather the sunshade can be installed and secured efficiently and easily by preparing only the support poles and the curtain cloth.

[0016] According to the invention of claim 2, the support pole can be adjusted to expand and contract in the axial direction and is equipped with a tension structure expansion adjustment means that is biased and extended in the axial direction, so the support pole can be stably and simply erected in the desired position. In other words, because the height of the support pole can be adjusted, the sunshade can be installed safely and efficiently according to the height of the eaves without using a stepladder or other lifting device.

[0017] According to the device described in claim 3, a pressure-type expansion and contraction adjustment means is provided that is configured to press the outer periphery of the pole by tilting the crimped ring body, making it possible to adjust and fix the sliding position in the axial direction of the support strut.Therefore, a simple configuration of tilting the crimped ring body relative to the pole and then releasing it makes it possible to easily adjust the expansion and contraction in the axial direction.

[0018] According to the invention described in claim 4, by sliding the slide operating body toward the upper cylinder, pushing the crimped ring against the elastic force of the annular elastic body to a horizontal position and releasing the tilt of the crimped ring, the second pole can be adjusted to an adjustable extension / retraction state. On the other hand, by stopping the operation of the slide operating body (releasing the finger), the slide operating body returns to its original position due to the elastic force of the annular elastic body, causing the crimped ring to be tilted and the second pole to be connected and fixed. Therefore, by sliding the slide operating body (up and down movement), the crimped ring can be tilted and released with a simple one-touch operation. Moreover, because the slide can be operated by hand, there is no need to climb a ladder and work at a high altitude, as is the case with conventional sunshade installations, and installation can be performed safely.

[0019] According to the device of claim 5, the holder is fitted to the outer periphery of the support pole, so there is no risk of the sunshade attached to the holder accidentally falling off the support pole along with the holder. Also, by adjusting the height of the holder, the height of the installed sunshade (curtain cloth) can be freely changed. Furthermore, the cloth can be stretched and supported by applying tension.

[0020] According to the invention described in claim 6, the curtain cloth can be easily attached to the holder using a tightening screw, and the holder can be fixed to the support pole at the same time as attaching the curtain cloth to the holder.

[0021] According to the invention described in claim 7, the holder is positioned by the ring, and the risk of the holder shifting position due to the frictional resistance of the ring against the support pillar (the holder slipping off due to loosening of the tightening screw, etc.) is reduced.

[0022] According to the invention of claim 8, the fixed plate reduces the force applied to the surface of the space where one end and the other end of the support column in the axial direction meet, thereby reducing the risk of damaging the support surface of the space. Furthermore, by making the fixed plate a trumpet-shaped plate that expands toward the abutting support surface, the fixed plate distributes the force applied to the support surface of the space where one end and the other end of the support column in the axial direction meet, further reducing the risk of damaging the support surface of the space.

[0023] According to the device described in claim 9, by using connecting poles according to the size (height) of the space in which the support pillar is to be installed, the support pillar can be erected in the desired space.

[0024] According to the invention described in claim 10, the curtain cloth not only serves as a sunshade and a privacy partition that can block views from outside, but also does not hinder the intake of wind into the building for ventilation. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a sunshade according to the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below are preferred examples of the present invention and are therefore subject to various technical limitations. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description.

[0027] As shown in FIG. 1, the sunshade 10 in this embodiment is intended to be installed in a space such as the entrance porch of a dwelling or under the eaves of a window or door, and is composed of a pair of support posts 1, 1 and a curtain cloth 2.

[0028] The support pillar 1 is simply installed in a space having support surfaces that abut on both sides in the axial direction, and is composed of a lower pipe 11 and an upper pipe 12, as shown in Figure 2. In other words, this support pillar 1 is configured so that the lower pipe 11 and the upper pipe 12 can be adjusted to expand and contract in the axial direction, and one side in the axial direction (lower side) abuts against a floor surface 91 such as the outside of a front door (entrance) or under the eaves where a window or door is located, and the other side in the axial direction (upper side) abuts against a top surface (ceiling) 92 such as the inside of a eaves or under the eaves, and is installed vertically in this space.

[0029] The lower pipe 11 is a part that constitutes the lower region of the support column 1, and has a lower fixed plate 6 attached to its lower end. This lower pipe 11 can be, for example, a thin, rod-shaped steel pipe with an outer diameter of 28 mm. The lower fixed platen 6 can be provided with, for example, an abutment portion 61 that abuts against the floor surface 91 that constitutes the installation space, and a pipe receiving cylinder portion 62 that is attached to the lower pipe 11. Therefore, the lower end side of the lower pipe 11 is detachably attached to the pipe receiving cylinder portion 62 of the lower fixed platen 6. It is desirable that the lower fixed platen 6 has a generally trumpet shape that widens toward the abutting surface (floor surface 91) side so that a wide contact area can be secured.

[0030] The upper pipe 12 is a part that constitutes the upper region of the support column 1 and is placed above the lower pipe 11, and is assembled so that its lower end is slidably fitted into the upper part of the lower pipe 11 and its upper side protrudes upward from the upper side of the lower pipe 11. This upper pipe 12 can be, for example, a thin, rod-like steel pipe with an outer diameter of 25 mm.

[0031] The upper pipe 12 can also be configured to include a connecting pole 13. In this embodiment, the upper pipe 12 is configured to include the connecting pole 13, and the support column 1 is made up of the lower pipe 11, the upper pipe 12, and the connecting pole 13.

[0032] The connecting pole 13 is a part that is further placed on the upper end side of the upper pipe 12, and is combined with the upper end side of the upper pipe 12 by fitting its lower end side into the upper end side of the upper pipe 12. The connecting pole 13 also has an upper fixed plate 7 attached to its upper end side. This connecting pole 13 can be, for example, a long, thin rod-shaped steel pipe with an outer diameter of 25 mm.

[0033] 3, the upper fixed plate 7 comprises, for example, a contact base 71 having a disk-shaped upper end and a cylindrical opening at the lower end, which contacts the inner top surface 92 of the eaves or overhang that constitutes the installation space, and a cylindrical receiving cylinder 72 fitted into the opening of the contact base 71. In other words, the receiving cylinder 72 protrudes downward from the contact base 71, and the upper end of the connecting pole 13 is detachably attached to the receiving cylinder 72 of the upper fixed plate 7. The upper fixed plate 7 can also be made to have a generally trumpet-shaped shape that widens toward the contacting surface (top surface 92).

[0034] The upper fixed platen 7 also includes a biasing spring 74 disposed between the receiving piece 73 provided inside the abutment base 71 and the upper end surface of the receiving cylinder 72, and a thin, disk-shaped abutment auxiliary body 75 made of, for example, rubber, disposed detachably on the upper end surface side of the abutment base 71. As a result, when the upper end of the connecting pole 13 is attached to the receiving cylinder 72 and the upper end surface side of the abutment base 71 is brought into abutment with the top surface 92, the biasing spring 74 elastically presses the abutment base 71 into abutment with the top surface 92. At this time, the flexibility of the abutment auxiliary body 75 also prevents damage to the top surface.

[0035] In addition, if the upper pipe 12 does not have a connecting pole 13, that is, if the support pillar 1 is composed only of the lower pipe 11 and the upper pipe 12, the upper fixed plate 7 is attached to the upper end of the upper pipe 12.

[0036] Each support pole 1 is also provided with a holder 4 for attaching the lower edge of the curtain cloth 2, a holder 5 for attaching the upper edge of the curtain cloth 2, and annular rings 8, 8 for positioning the holders 4, 5, respectively.

[0037] The curtain cloth 2 is a flexible sheet material that blocks sunlight from entering the building, and as shown in Fig. 4, it has eyelets 21 at the left and right corners on the lower edge that allow it to be attached to the support pole 1. In addition, as shown in Fig. 5, the curtain cloth 2 has eyelets 22 at the left and right corners on the upper edge that allow it to be attached to the support pole 1. The screen cloth 2 is made of a rectangular sheet-like flexible material, and may be, for example, a translucent sheet, an opaque sheet, a woven fabric, or a nonwoven fabric made of a synthetic resin material such as polyethylene resin or polyvinyl chloride resin, but is not limited to these. The screen cloth 2 may also be integrally formed from a breathable flexible material such as a mesh sheet.

[0038] As shown in Figure 4, the holder 4 is a ring (cylindrical) body that is attached to the outer periphery by being inserted into the axial end of the support pole 1, and is equipped with a fixing hole 41 that allows the lower edge of the curtain cloth 2 to be attached, and a fixing bolt 19 that is inserted through a grommet 21 provided at the corner of the lower edge of the curtain cloth 2 and screwed into the fixing hole 41. FIG. 4 shows the state in which the curtain cloth 2 is attached and fixed to the holder 4 by inserting a fixing bolt 19 into an eyelet 21 provided at the right corner of the lower edge of the curtain cloth 2 .

[0039] As shown in Figure 5, holder 5, like holder 4, is a ring (cylindrical) body that is attached to the outer periphery by being inserted into the axial end of support pillar 1, and is provided with a fixing hole 51 that allows the upper edge of curtain cloth 2 to be attached, and a fixing bolt 19 that is inserted through a grommet 22 provided at the corner of the upper edge of curtain cloth 2 and screwed into fixing hole 51. FIG. 5 shows the state in which the curtain cloth 2 is attached and fixed to the holder 5 by inserting a fixing bolt 19 into an eyelet 22 provided at the left corner of the upper edge of the curtain cloth 2 .

[0040] In this way, the curtain cloth 2 can be attached to the holders 4 and 5 by screwing them together, and can be attached to any height on the support pole 1. In other words, the holders 4 and 5 can easily and firmly support the curtain cloth 2 in tension on the support pole 1 using the fixing bolts 19. Furthermore, the height of the curtain cloth 2 relative to the support pole 1 can be freely adjusted by adjusting the attachment positions of the holders 4 and 5 to the support pole 1.

[0041] The ring 8 is an annular member that is fitted onto the outer periphery of, for example, the lower pipe 11 or the connecting pole 13 to which the screen fabric 2 is attached, and functions as a guide for adjusting the position of the holders 4 and 5. In other words, by fitting this ring 8 onto the outer periphery of the lower pipe 11 or the connecting pole 13 and lowering the holders 4 and 5 until they abut against the ring 8, the height of the screen fabric 2 can be easily positioned, making the installation of the screen fabric 2 on the support pole 1 extremely simple and easy. The ring 8 can be made of, for example, a rubber member. The required number of rings 8 are provided, just like the holders 4 and 5.

[0042] The support column 1 also includes a tension connector 3, which is a tension structure tension adjustment means that allows for axial expansion and contraction adjustment and is biased in the axial direction to expand. This tension connector 3 allows the length of protrusion of the upper pipe 12 relative to the lower pipe 11 to be adjusted, and is arranged to surround the outer periphery of the lower pipe 11 and upper pipe 12, spanning the upper part of the lower pipe 11 and the upper pipe 12 that protrudes upward from the upper part of the lower pipe 11.

[0043] This tension connector 3 can have a configuration similar to the telescopic adjuster proposed by the applicant and disclosed in Utility Model Registration No. 3227376 or Utility Model Registration No. 3244844. This allows for tensioning operation to fix the upper pipe 12 to the lower pipe 11, and tension release operation.

[0044] That is, as shown in Fig. 6, this tension connector 3 can be put into a tension operation state by removing the safety bolt 39, pulling out the fixing pin 34a provided in the operation area, and then pressing the operation button (one-touch button) 34, which is the slide operation body, with a finger as shown in Fig. 7. In the tension operation state, the upper pipe 12 can expand and contract relative to the lower pipe 11, so if the upper pipe 12 is pulled upward in this state, the support column 1 can be arranged in a tension structure between the floor surface 91 and the ceiling surface 92, which are the support surfaces of the support column 1.

[0045] On the other hand, when the pressure on the operation button 34 is released, the tension connector 3 enters a tension release state, and the upper pipe 12 is firmly connected and fixed in place to the lower pipe 11. In the tension release state, the safety bolt 39 is then attached to its original position, and the fixing pin 34a is returned to its original state.

[0046] Specific examples of such tension connector 3 are shown in Figures 8 and 9. Figure 8 shows the upper pipe 12 in a connected and fixed state (tensioning operation released state), and Figure 9 shows the upper pipe 12 in a connected and fixed released state (tensioning operation state). The tension connector 3 comprises an expansion / contraction adjuster body 30, an operating body receiving portion 33, an operating button , a crimped annular body , a guide cylinder 37, and an annular elastic body .

[0047] The telescopic adjuster body 30 is composed of a hollow cylindrical upper cylindrical body 32 into which the lower end of the upper pipe 12 is fitted, and a hollow cylindrical lower cylindrical body 31 which is integrally connected to the lower part of the upper cylindrical body 32, to which the upper end of the lower pipe 11 is attached from below, and whose upper end located inside the upper cylindrical body 32 has an inclined portion 31a.

[0048] The operating body receiving portion 33 is provided in the length direction of the telescopic adjuster body main body 30 from the outer wall portion of the upper cylindrical body 32 to the outer wall portion of the lower cylindrical body 31 . The operation button 34 is an operation body having an operation protrusion 35 that protrudes inward, and is attached to the operation body receiving portion 33 so that this operation protrusion 35 can move in the longitudinal direction of the telescopic adjustment body main body 30.

[0049] The crimped annular body 36 is disposed on the inclined portion 31 a of the lower cylindrical body 31 inside the upper cylindrical body 32 , with a portion of its inner periphery protruding and in contact with the outer periphery of the upper pipe 12 . The guide cylinder 37 is integrated with the crimped annular body 36, which is disposed on the outer periphery of the upper pipe 12 on the crimped annular body 36, and the operation protrusion 35 is connected to the outer periphery thereof.

[0050] The annular elastic body 38 is disposed between the upper side step 32a in the upper cylindrical body 32 and the crimped annular body 36, and applies elastic force to the crimped annular body 36, the guide cylindrical body 37, and the operation projection 35 toward the lower cylindrical body 31, and also applies elastic force to urge the operation button 34 outward and protrude via the operation projection 35. An example of the annular elastic body 38 is a coil spring.

[0051] 8, when the fixing pin 34a is pulled out of the tension connector 3, the elastic force of the coil spring 38, which is an annular elastic body, causes the operating button 34 serving as the operating body to protrude outward, and the crimped annular body 36 assumes an inclined state, positioned on the inclined portion 31a of the lower cylindrical body 31. Then, the inner periphery of the crimped annular body 36 protrudes and crimps onto the outer periphery of the upper pipe 12, thereby connecting and fixing the upper pipe 12.

[0052] 9, when the operation button 34 is pressed as shown by the large black arrow, the operation projection 35 provided on the inside slides toward the upper cylinder 32 as shown by the small black arrow, pushing up the crimped ring 36 and the guide cylinder 37 against the elastic force of the coil spring 38, and the crimped ring 36 becomes horizontal. When this happens, the inner periphery of the crimped ring 36 no longer protrudes toward the outer periphery of the upper pipe 12, and the upper pipe 12 enters a connection / fixture release state in which it can be adjusted for extension and contraction, and the fitting position of the upper pipe 12 relative to the lower pipe 11 can be freely adjusted.

[0053] When the pressure on the operation button 34 is released, the elastic force of the coil spring 38 causes the operation projection 35 and the operation button 34 to return to their original positions, and the crimped annular body 36 returns to its inclined state and is fixedly connected.

[0054] When installing the support pole 1 configured as above, first, the upper holder 5 is aligned with the support pole 1, and the upper edge of the curtain cloth 2 is attached to the holder 5. Next, at the installation location, the user holds the lower pipe 11 with one hand and the upper pipe 12 with the other, sets the support column 1 up so that it is perpendicular to the floor surface 91, and then adjusts the length of the support column 1 using the tension connector 3. That is, with the lower fixing plate 6 attached to the lower end of the lower pipe 11 in contact with the floor surface 91, the support column 1 is supported so that it is perpendicular to the floor surface 91, and by tensioning using the tension connector 3, the upper region of the upper pipe 12 is pulled out from the lower pipe 11, and the upper fixing plate 7 attached to the upper end of the connecting pole 13 is fixed by abutting it against the ceiling surface 92. Then, with the curtain cloth 2 stretched taut downward, the lower holder 4 is aligned with the support column 1, and the lower edge of the curtain cloth 2 is attached to the holder 4. In this way, as shown in FIG. 10, the sunshade 10 can be efficiently extended and supported on the outside of the window W in a space-saving manner.

[0055] <Other embodiments> In the above-described embodiment, various technical limitations are imposed for the sake of convenience of explanation, but the scope of the present invention is not limited to these. For example, the tension connector 3 provided on the support post 1 is not limited to one equipped with a pressure-type expansion / contraction adjustment means using a crimped annular body 26 (the expansion / contraction adjustment body disclosed in Utility Model Registration No. 3227376 or Utility Model Registration No. 3244844 proposed by the applicant). That is, as shown in FIG. 11, the support column 1 may be provided with a tensioning system in which the support column 1 is extended or contracted by rotating a jack portion 53 without using the tensioning connector 3. In Figure 11, the support pillar 1 is installed vertically in the space between the floor surface 91 and the top surface 92, and by rotating the jack part 53 in the direction of the arrow, it is extended by a length α from the start line to the stop line.

[0056] In addition, although not shown, the tension connector 3 may also be equipped with an operating body rotation type extension / retraction adjustment means, in which the inner diameter gradually decreases by rotating a cylindrical (annular) operating body provided on the outer periphery of the connecting part between the lower pipe and the upper pipe in the circumferential direction, and the sliding position can be adjusted and fixed by tightening the operating body.

[0057] Furthermore, in the present invention, the holder 4 is not limited to a ring (cylindrical) body fitted onto the outer periphery of the support pillar 1, but may also be, for example, a holding member that can be easily crimped by inserting it radially into the support pillar 1 (lower pipe 11 or connecting pole 13). [Industrial Applicability]

[0058] The sunshade of this invention can be used, for example, as an indoor partition (room divider), and can be widely used as a space-saving, simple, and efficient sunshade cloth to be installed in gardens or verandas facing window or door openings in houses and condominiums. Therefore, it is expected to have an energy-saving effect by suppressing indoor temperature increases in summer and contributing to reduced energy consumption. Moreover, because the sunshade of this invention is installed vertically, it can appeal to a wide range of people, including those who have given up on installing a sunshade because they did not have enough space to install one.

Claims

1. a pair of support columns that are simply erected in a space having support surfaces that contact one side and the other side in the axial direction; A curtain cloth stretched and supported between the support columns to block sunlight entering the building; It consists of Each of the support poles has a holder to which the curtain cloth is attached and is installed vertically in the space. A sunshade characterized by:

2. The support column is provided with an expansion / contraction adjustment means having a tension structure that allows expansion / contraction adjustment in the axial direction and is biased in the axial direction to extend.

2. The sunshade according to claim 1.

3. The support column is composed of a plurality of fitted poles, and is provided with a pressure-type expansion and contraction adjustment means configured to adjust and fix the sliding positions of the poles by pressing the outer periphery of the pole with the inclination of a pressure-contact annular body arranged on the outer periphery of the inner pole.

2. The sunshade according to claim 1.

4. The support struts are: The first pole and a second pole that can be fitted within the first pole; an extension / retraction adjusting means for attaching the upper end of the first pole and connecting and fixing the second pole and then releasing the second pole, thereby enabling the second pole to be extended or retracted relative to the first pole; and The expansion / contraction adjusting means is an extension / retraction adjuster body including a hollow cylindrical upper cylinder into which the lower end of the second pole is fitted, and a hollow cylindrical lower cylinder integrally connected to the lower part of the upper cylinder, into which the upper end of the first pole is fitted from below, and whose upper end located inside the upper cylinder is an inclined part; a slide operation body receiving portion provided in the length direction of the telescopic adjuster body body from the outer wall portion of the upper cylindrical body to the outer wall portion of the lower cylindrical body; a slide operation body attached to the slide operation body receiving portion so as to be slidable in the length direction of the telescopic adjustment body body, and having an operation protrusion at an inner protruding end; a crimped annular body inclinedly disposed inside the upper cylindrical body so that a part of its inner periphery protrudes onto the inclined portion of the lower cylindrical body and contacts the outer periphery of the second pole; a guide cylinder that is integrated with the crimped annular body and that is disposed on the outer periphery of the second pole on the crimped annular body, and that has an operation protrusion of the slide operation body connected to its outer periphery; an annular elastic body that is disposed between the upper side step portion in the upper cylindrical body and the crimped annular body and that applies elastic force to the crimped annular body, the guide cylindrical body, and the slide operation body toward the lower cylindrical body; Equipped with When the slide operation body is slid toward the upper cylinder body, the operation protrusion pushes up the crimped annular body and the guide cylinder body against the elastic force of the annular elastic body, bringing the crimped annular body into a horizontal state, eliminating the protrusion of its inner periphery toward the outer periphery of the second pole, and bringing the second pole into an adjustable, connected, fixed, and released state. When the slide operation body is restored to its original position by the elastic force of the annular elastic body, the crimped annular body returns to its inclined state, and the inner periphery of the crimped annular body protrudes and crimps onto the outer periphery of the second pole, thereby connecting and fixing the second pole.
