Description

[Detailed description of the invention] Industrial application field This invention is a sunshade and rainscreen that is permanently fixed at the entrance of a house, etc., by attaching it to the corner of the tension frame of the sunshade and rainscreen cloth. This relates to a three-sided elbow in the framework of a sunshade and rain shield whose eaves can be adjusted to any desired angle.

PRIOR TECHNOLOGY In the past, many tensile frames for sunshade and rainproof cloth have been proposed, but in general, pipes are bent at a certain angle and fixed to windows, doorways, etc., or they are fixed to arm bars or support bars. It was suspended or lowered upward with a rope using the root as a fulcrum.

Problems that the invention aims to solve: However, with the conventional method of stretching the sunshade and rainscreen cloth as described above, the pipe is already bent at a certain angle, so the problem is that the eaves of the sunshade and rainscreen cloth cannot be adjusted to an arbitrary angle. The dot was hot.

In addition, all of the sun and rain shield eaves require time and effort to install, have poor workability, and are not suitable for installation by amateurs.

The object of the present invention is to eliminate the above-mentioned conventional drawbacks, to provide a three-sided elbow in a tension framework for a sunshade and rain shield, which allows easy adjustment of the angle of the eaves, and which can be easily installed even by an amateur.

Means for Solving the Problems In order to achieve the above object, the present invention provides an L-shaped joint body A in which a horizontal rod joint 1 and an arm rod joint 1' are integrally formed, and a rotary joint of a vertical rod. 4, a notch 2 is provided extending from the outer corner A of the horizontal rod joint 1 of the L-shaped joint body A to a part of the arm rod joint 1' of the joint body A, and The rotary joint 4 is also provided with a notch 3 similar to the notch 2, and the rotary joint 4 is attached to the corner A by means of a fitting 5.
This is a three-sided elbow of the framework of a sunshade and rain shield, characterized in that the base part (R) is fixed so as to be rotatable.

Function As described above, the present invention is such that the base part B of the vertical rod rotation joint 4 is rotatably displaceable by the fitting 5 at the outer corner part A of the horizontal rod joint 1 of the L-shaped joint body A. Since the notches 2 and 3 are fixed to each other and are similar to each other in part of the arm rod joint 1' and the rotation joint 4,
Adjustment of the angle between arm rod joint 1' and rotation joint 4 is as follows:
Rotating joint 4 from the expanded position using the fixed part as a fulcrum
By rotating the rotary joint 4 so as to fold it in the range until the notch 3 overlaps the peripheral surface of the arm rod joint 1' on the other side, the rotary joint 4 can also be folded in the notch 2 of the arm rod joint 1'. The circumferential surface of the joint 4 functions to fit into the arm-rod joint 1', and the rotary joint 4 can be adjusted to any angular position with respect to the arm-rod joint 1', and can be fixed at a desired angle.

Embodiment An embodiment of the present invention will be described with reference to the drawings. The three-way elbow of the present invention consists of the structural members shown in FIGS. It is an integrally formed L-shaped fitting body, which is formed as a hollow tube, but can also be formed as a rod according to design needs. The horizontal rod joint 1 is a cylindrical body with a bottom, and a screw hole is bored in the fixed portion approximately in the center of the corner portion A of the bottom surface. The arm rod joint 1' has a notch 2 formed extending from the corner A to a part of the joint body. As shown in FIG. 6, a notch 3 is formed in the rotary joint 4 of the vertical rod extending from the base to a part of the rotary joint 4 in a similar manner to the notch 2. As shown in FIG. Reference numeral 5 denotes a fitting such as a screw rod, which fixes the rotary joint 4 to the corner portion A of the L-shaped joint body A. Second
As shown in Figures 4 to 4, the base part B of the rotary joint 4 is attached to the fixed part of the corner part A of the L-shaped joint main body A so that it can be freely rotated by a fitting 5 such as a threaded rod. It is attached.

As shown in FIG. 9, 6 and 6' are horizontal rods, and 7 is a vertical rod, and the horizontal rods and the vertical rods constitute a frame body. 8 is an arm rod, one end of which is inserted into the arm rod joint 1'. The frame body of the horizontal and vertical rods and the arm rods constitute the framework of the sunshade and rain shield. 9
is a tent, and 10 is an entrance.

The three-way elbow of the present invention, as shown in Figure 1,
The base part 4 of the vertical rod rotation joint 4 is an L-shaped joint body A.
The pivot joint 4 is attached to the outer corner A of the horizontal rod joint 1, and the pivot joint 4 is rotated with respect to the arm joint 1' using the fixture 5 as a fulcrum. As shown in FIG.
3, the angle between the arm rod joint 1' and the rotation joint 4 can be adjusted by moving the notch 3 of the rotation joint 4 from the expanded position using the attachment 5 as a fulcrum. By rotating it so as to fold it in the range until it overlaps with the circumferential surface of the arm rod joint 1', the circumferential surface of the rotation joint 4 also works to fit into the notch 2 of the arm rod joint 1'. It becomes possible to adjust the rotation joint 4 to any angle with respect to the arm rod joint 1', and it is possible to fix the rotation joint 4 at a desired angular position.

Since the present invention is configured as described above,
As shown in Fig. 9, a three-way elbow can be attached to the corner of the framework of the sunshade and rain shield.To explain how it is implemented, for example, when it is attached to the top surface of the doorway 10, it can be attached to the window. Appropriate mounting brackets are nailed to the left and right sides, and the arm bar 8 is horizontally projected from the front from the mounting brackets and inserted into the arm bar joint 1', and the vertical bracket is hung at an arbitrary angle from the upper part of the window. By inserting the lower end of the rod 7 into the rotation joint 4 and then inserting the horizontal rod 6 into the horizontal rod joint 1, a skeleton as a frame is completed. By covering the tent 9 on this frame, a sunshade and rain shield can be formed. This three-way elbow has a short cylindrical joint protruding in three directions in a three-pronged shape, and a metal pipe is inserted and welded into the cylindrical body that makes up the elbow. In other words, the pipe is cut into appropriate dimensions according to the width of the wall of the building corresponding to the entrance and exit, taking into account the length or angle of inclination, etc., to form a frame. Drill a hole in the pipe and secure it to the wall using nails or other mounting hardware.

Effects of the invention As mentioned above, the present invention attaches the vertical rod rotation joint base to the outer corner of the horizontal rod joint of the L-shaped joint body using a fixture, and also attaches the base of the vertical rod rotation joint to the outer corner of the horizontal rod joint of the L-shaped joint body, and also attaches the base of the vertical rod rotation joint to the arm rod joint and the rotation joint in a similar shape. Since the cutout parts are arranged to face each other, the rotary joint can rotate freely using the fixed part as a fulcrum, and the rotary joint for inserting the vertical rod can be rotated as if folded over the arm rod joint. By fixing the sunshade in a fixed position, the inclination angle of the sunshade can be easily adjusted.

Further, each joint and each frame rod can be easily attached and detached, and furthermore, by removing each frame rod from each joint, it is possible to easily and tidy up the structure without taking up much space, which is a practical benefit.
