(Embodiment 1)
FIG. 1 is a configuration diagram showing a tension rod according to the first embodiment of the present invention. The tension rod 100 is provided with a partially divided rod main body 1 and a threaded portion 11 between the divided ends, and the threaded portion 11 is screwed and connected to a nut 12 which is a sleeve-shaped member from both sides to form a nut. It is composed of an expansion / contraction portion 2 that expands / contracts the entire rod body 1 in the longitudinal direction by rotation of the rod body 1, and fixing portions 3 provided at both ends of the rod body 1.

In the expansion / contraction portion 2, female screws in opposite directions are formed on the inside of the nut 12 from both sides. Further, male screws in opposite directions are provided at the ends of the divided rod main bodies 1, and the male screws are screwed into the female screws of the nut 12 to connect the rod main body 1 to one. By rotating the nut 12, the rod body 1 expands and contracts in the longitudinal direction. As the configuration of the expansion / contraction portion 2 for adjusting the overall length, another known configuration may be adopted.

Next, the fixing portion 3 is provided with angle adjusting portions 31 at both ends of the rod body 1 so that the angle can be adjusted. As shown in FIG. 2A, the angle adjusting portion 31 includes a bracket 32 provided at the end of the rod body 1 and a bracket 34 provided on the back surface of the fixing plate 33, and the brackets 32 and 34 face each other. Concavities and convexities 35 that mesh with each other are formed on the surface. As shown in FIG. 2B, the brackets stacked so that the unevenness 35 meshes with each other are fastened to each other by bolts and nuts (not shown) penetrating the center, and the fixing plate 33 is fixed to the rod body 1 at a predetermined angle. can. The angle adjusting unit 31 makes it possible to set a state in which the rod body 1 has an angle of at least 45 degrees with respect to the resin surface 36 of the fixing plate 33.

A resin plate 36 is provided on the surface of the fixing plate 33 of the fixing portion 3. As shown in FIG. 3, the resin plate 36 has a structure in which a thin chloroprene rubber having a non-slip function is attached to a plastic fixing plate 33. A large number of irregularities are formed on the surface of the chloroprene rubber, and the irregularities obtain a frictional force with the wall surface. Further, as shown in FIG. 4, a structure in which a sponge-shaped natural rubber is attached to a plastic fixing plate 33 may be used. Further, ethylene propylene diene rubber (EPDM) having appropriate flexibility may be used. These surfaces are finely porous.

FIG. 5 is an explanatory diagram showing a usage state of the tension rod. The angle adjusting portion 31 adjusts the resin surface 36 of the fixing plate 33 so as to be 45 degrees with respect to the longitudinal direction of the rod body 1 to fix the angle. Subsequently, the length of the entire rod body 1 is adjusted by the expansion / contraction portion 2, and the fixing portion 3 is pressed against the corner portion of the wall surface W. Subsequently, the nut 12 is rotated to extend the rod body 1, and the solid plate 33 of the fixing portion 3 is pressed against the wall surface W. The resin surface 36 of the fixing portion 3 is pressed against the wall surface W and comes into close contact with the wall surface W.

Since the fixing portion 3 is inclined at 45 degrees, the axial force of the rod body 1 can be separated into a force perpendicular to the wall surface W and a force in the horizontal direction. The force in the horizontal direction is received by the frictional force between the wall surface W and the resin surface 36.

When the surface of the wall surface W is a mirror surface without unevenness, the material of the resin surface 36 is adsorbed to generate a high frictional force, so that the fixing plate 33 is fixed to the wall surface W. When the surface of the wall surface W has small irregularities (plastered wall such as mortar or diatomaceous earth), the irregularities bite into the resin surface 36 to generate a large frictional force and hinder the movement in the surface direction. As a result, the fixing portion 3 is closely fixed to the wall, and the tension rod 100 is fixed at the corner portion.

When removing the tension rod 100, the nut 12 is rotated to contract the rod body 1 and release the force on the wall surface W. As a result, the tension rod 100 can be easily removed from the wall surface W.

According to the above-mentioned tension rod 100, the tension rod 100 can be installed in the dead space at the corner portion of the wall surface W, so that the space can be effectively used.

(Embodiment 2)
FIG. 6 is an explanatory view showing a tension rod according to the second embodiment of the present invention. The tension rod 200 has substantially the same configuration as the tension rod 100 according to the first embodiment, but has a position fixing structure 210 for piercing a needle with respect to the wall surface W. Since other configurations are the same as those in the first embodiment, the description thereof will be omitted. As shown in FIG. 3A, the position fixing structure 210 is provided with a push-in portion 212 having a needle 211 at the tip of a part of the fixing plate 33. The pushing portion 212 is inserted into the hole 213 of the fixing plate 33 and held by frictional force. The needle 211 at the tip is buried in the resin surface 36. The top of the push-in portion 212 protrudes from the fixing plate 33.

As shown in FIG. 3B, two position fixing structures 210 are provided with respect to the fixing plate 33, but the position fixing structure 210 is not limited to this. The needle 211 is about the size of a push pin needle. A long one is preferable, but the needle diameter is preferably small in order to reduce the needle mark on the wall surface W. The position fixing structure 210 does not have to be in the form of inserting a needle as long as it has a structure in which unevenness that prevents the wall surface W and the fixing plate 33 from moving in the horizontal direction is formed between the fixing plate 33 and the wall surface W. good.

FIG. 7 is an explanatory diagram showing a usage state of the tension rod. The fixing plate 33 is pressed against the wall surface W, and the pushing portion 212 of the position fixing structure 210 is pushed in to insert the needle 211 into the wall surface W. As a result, the fixing plate 33 is fixed in position in the direction parallel to the wall surface W. In this state, the nut 12 is rotated to extend the rod body 1 in the longitudinal direction, and the fixing portion 3 is pressed against the wall surface W. The resin surface 36 of the fixing portion 3 is pressed against the wall surface W and comes into close contact with the wall surface W.

Further, the movement of the fixing plate 33 in the direction parallel to the wall surface W is blocked by the frictional force of the resin surface 36 and the shear stress of the needle 211 of the position fixing structure 210, and the fixing portion 3 is closely fixed to the wall.

According to the above-mentioned tension rod 200, since the tension rod 200 can be installed in the dead space at the corner portion of the wall surface W, the space can be effectively used.

(Embodiment 3)
FIG. 8 is a perspective view showing the tension structure according to the third embodiment of the present invention. The tension structure 300 has a fixing plate 301 in which strip-shaped plates are connected at right angles and rotatably, and a tension rod 100 is provided between the fixing plates 301. The tension rod 100 is a rod main body 1, a sleeve-shaped fixing portion 302 provided at both ends of the rod main body 1 and attached to the fixing plate 301, and one end of the rod main body 1 and a sleeve of the fixing portion 302 are screwed and connected. It is composed of an expansion / contraction portion 2 that expands / contracts in the longitudinal direction by the rotation of the rod body 1.

A resin surface 303 is provided on the back surface (contact surface with the wall surface W) of the fixing plate 301. The resin surface 303 is made of, for example, chloroprene rubber, and a large number of irregularities are formed on the surface thereof, and frictional force with the wall surface W is obtained by the irregularities. Further, the structure may be such that a sponge-shaped natural rubber is attached to a plastic fixing plate 301. Further, ethylene propylene diene rubber (EPDM) having appropriate flexibility may be used. These surfaces are finely porous.

A mountain-shaped protrusion 304 is provided on a part of the fixing plate 301, and the fixing portion 302 of the rod body 1 is fixed to the slope of the protrusion 304. The fixing plates 301 are connected to each other by a hinge 305 at the short side portion and are slightly rotatable. As a result, the tension rod 100 is fixed to the fixing plate 301 at an angle of approximately 45 degrees. Since the fixing plate 301 rotates slightly, the angle between the tension rod 100 and the fixing plate 301 is connected or fixed at an angle of plus or minus several degrees with respect to 45 degrees. That is, they are connected or fixed within an angle range including at least an angle of 45 degrees (for example, 40 degrees or more and 50 degrees or less).

Next, the attachment of the tension structure 300 to the wall surface W will be described. First, the fixing portion 302 of the rod body 1 is rotated to adjust the length in the longitudinal direction to be slightly shorter, and the fixing plate 301 is pressed against the wall surface W at the corner portion of the wall as shown in FIG. In this state, the length of the entire rod body 1 is extended by the telescopic portion 2, and the fixing plate 301 is pressed against the corner portion of the wall surface W. The resin surface 303 of the fixing plate 301 is pressed against the wall surface W and comes into close contact with the wall surface W.

The axial force of the rod body 1 can be separated into a force perpendicular to the wall surface W and a force horizontal to the wall surface W because the slope of the protrusion is inclined at 45 degrees. The force in the horizontal direction is received by the frictional force between the wall surface W and the resin surface 303. By providing the resin surface 303 on more than half of the area of the fixing plate 301, a high frictional force can be obtained as a whole.

When the surface of the wall surface W is a mirror surface without unevenness, the material of the resin surface 303 is adsorbed to generate a high frictional force, so that the fixing plate 301 is fixed to the wall surface W. When the surface of the wall surface W has small irregularities (plastered wall such as mortar or diatomaceous earth), the irregularities bite into the resin surface 303 to generate a large frictional force and hinder the movement in the surface direction. As a result, the fixing plate 301 is closely fixed to the wall, and the tension structure 300 is fixed at the corner portion.

When the tension structure 300 is removed, the rod body 1 is rotated to contract the rod body 1 and release the force on the wall surface W. As a result, the tension structure 300 can be easily removed from the wall surface W.

According to the above-mentioned tension structure 300, the tension rod 100 can be installed in the dead space at the corner portion of the wall surface W, so that the space can be effectively used.
