Description

[Detailed Description of the Invention] This invention relates to a universal joint that connects the corner parts of the framework of a decorative tent installed in front of a store such as a store so that the angle can be adjusted slightly.

Decorative tents are installed above the entrances and exits of shops, restaurants, etc., and are used as sunshades, rain shelters, and billboards for advertising. That is, as shown in FIGS. 1 and 2, a decorative tent 1 that is rectangular when viewed from the front and triangular when viewed from the side is installed above the entrance 2 of a store. It is constructed by spreading tent cloth around a frame 3 as shown in the figure. The width W, depth D, and height H of the frame 3 of the decorative tent 1 vary depending on the frontage of the store, the width of the aisle in front of the store, and the height of the tent attachment part. Frame 3 was manufactured to order by cutting and welding steel materials according to the situation of the store. For this reason, the steel frame material constituting the frame 3 cannot be used for general purposes, leading to an increase in manufacturing costs.

In order to overcome these drawbacks of the frames of conventional decorative tents, the present inventor designed the structure so that the number of combinations of frame materials could be changed freely, or configured the frame materials themselves to be expandable and contractible. By doing so,
We have devised a frame whose width W, depth D, and height H can be easily changed. That is, as shown in FIGS. 4 to 6, this frame 3a is connected to the joint 5 of a fixed frame 7 in which angle members 4a and 4b having an L-shaped cross section are connected by joints 5 and 6 in a U-shape with an open bottom. ，
6, the upper ends of the inclined frame members 8, 8a are pivotally connected to
The intermediate inclined frame member 8a is connected to the connecting portion 9b of the universal joints 9, 9 having a to 9c, and the intermediate inclined frame member 8a is connected to the universal joint 9, 9.
The outer cylinder 12 and the inner cylinder 1 are connected to the side surface of the lower frame member 10 which is fitted into the connecting part 9a and spanned between the joints 9 and 9, and one end is connected to the remaining connecting part 9c of the universal joints 9, 9.
3 and the other end of the connecting frame member 11 whose length can be freely adjusted is connected to the vertical angle member 4b of the fixed frame portion 7.
It is connected vertically to the bottom edge of the Further, one end of another connecting frame member 14 having the same configuration as the connecting frame member 11 is connected to the intermediate portion of each inclined frame member 8, 8a, and the other end of this connecting frame member 14 is connected to a fixed frame member. It is connected to a mounting plate 30 that is fixed to the middle part of the vertical angle member 4b of the section 7 or to the mounting wall surface of the decorative tent 1.

In the frame 3a configured as described above,
The frontage can be changed depending on the number of horizontal angle members 4a, 4a of the fixed frame part 7 connected, and the vertical angle members 4b, 4b and the inclined frame members 8,
The height can be adjusted by changing the length of 8a, and the depth can be adjusted by changing the lengths of the connecting frame members 11, 14 and the inclined frame members 8, 8a.

By the way, when adjusting the height and depth of the frame 3a in this way, the angle between the left and right inclined frame members 8, 8 and the lower frame member 10, and the left and right connecting frame members 11, 11 and the lower frame member 10 are adjusted. The angle between the inclined frame members 8, 8 and the connecting frame member 1 always remains a right angle.
The angle formed with 1 and 11 changes. Furthermore, in the case where a store with decorative tents is located at a corner of the street, so-called a corner store, the decorative tents 1 and 1 are placed on two sides of the store facing the street, respectively, as shown in Figures 7 and 8.
1, and a triangular auxiliary tent 15 is stretched between the ends of the two decorative tents 1, 1. When installing decorative tents 1, 1 in such a corner store, the above-mentioned frames 3 are installed on each side 16a, 16b of the store, as schematically shown in FIG.
a, 3a are fixed, and a connecting inclined frame member 17 for tensioning the above-mentioned auxiliary tent 15 is stretched between the lower corners of each frame 3a, 3a. For this reason, each frame 3a to which the end of this connection inclined frame member 17 is to be connected,
In the lower corner part of 3a (parts a and b in Fig. 9),
As shown in FIG. 10, a connecting portion 9 into which the lower frame member 10, the inclined frame member 8, and the connecting frame member 11 are fitted, respectively.
A universal joint 9A having four connecting portions 9a to 9d, including connecting portions a to 9c and a connecting portion 9d into which the end of the connecting inclined frame member 17 is fitted, must be used.
However, as mentioned above, the depth of the decorative tent 1 changes depending on the width of the road in front of the store, so the depths of the frames 3a, 3a fixed to the two sides of the store are not always the same, and the depth of each frame 3a, 3a is different. The angle between the connecting frame member 11 and the connecting inclined frame member 17 changes around 45 degrees.

Therefore, the universal joint 9A is provided at the lower corner of the frames 3a, 3a fixed to different surfaces 16a, 16b.
shall have a structure in which the angle α between the connecting portions 9b and 9c and the angle β between the connecting portions 9c and 9d can be adjusted while the connecting portions 9a and 9b and the connecting portions 9a and 9c are held at right angles. is necessary.

The universal joint for the frame of a decorative tent of the present invention was devised in view of the above-mentioned circumstances.

Hereinafter, the present invention will be explained with reference to drawings showing embodiments.

11 to 18 show an embodiment of the universal joint 9A of the present invention. Of the four short cylindrical connecting portions 9a, 9b, 9c, and 9d constituting the universal joint 9A, two connecting portions 9a and 9b are integrally formed so as to be perpendicular to each other via a connecting portion 18. However, the remaining connecting portions 9c and 9d are formed separately and independently. As shown in FIGS. 11 to 13, the connecting portion 18 connecting the integrally formed connecting portions 9a and 9b has a thickness such that the thickness of the connecting portion 18 becomes thinner toward the outside of the curve of the connecting portions 9a, 9b. A curved surface portion 19 is formed which is inclined and recessed with respect to a plane including the center line of the short cylindrical connecting portions 9a and 9b. This curved surface portion 19 has connecting portions 9a,
U groove portions 20a obliquely intersecting the center line of 9b,
20b are connected by a connecting surface portion 21, and one end of a screw hole 22 provided at an angle in the connecting portion 18 is opened in each U groove portion 20a, 20b. The U groove portions 20a and 20b are formed in this screw hole 2.
As shown in FIG. 13, it is bent convexly in the length direction with the ridge line 31 as the boundary.

On the other hand, among the separately formed connecting parts 9c and 9d, the connecting part 9c is formed as shown in FIG. 11 and FIGS. 14 to 16. That is, the head 2 of the connecting portion 9c has an end 23a formed into a hemispherical shape.
3 has a slit-like cut 24 formed in the diameter direction, and a through hole 25 that penetrates the head 23 in a direction perpendicular to the cut 24. This through hole 25 has a connecting portion 9 in the upper half portion 25a from the bottom to the top with the cutout 24 as a boundary.
The width in the length direction of c is an inclined elongated hole that gradually becomes longer in a triangular shape, and the lower half part 25b has a bolt 26 (the first
The hole should be large enough to allow the head (Fig. 1) to enter. Next, as shown in FIG. 11, a flat plate part 28 that can be inserted into the cutout 24 of the head 23 of the connecting part 9c is formed at the end of the remaining connecting part 9d.
At the end of 8, there is a circular hole 2 through which the bolt 26 can pass freely.
9 is drilled.

The integral connection parts 9a, 9 formed in this way
When connecting b and separate connecting parts 9c and 9d with bolts 26 and using it as a universal joint, the head 23 of the connecting part 9c is connected to the U groove part 20b (or 20a).
The flat plate part 28 at the end of the other connecting part 9d is inserted into the cutout 24 of the head part 23. Next, the bolt 26 that has passed through the through hole 25 and the circular hole 29 is first loosely screwed into the screw hole 22 that opens in the U groove 20b (or 20a).
Assemble as shown. With each of the connecting portions 9a to 9d assembled in this manner, the connecting portion 9a and the connecting portion 9c and the connecting portion 9a and the connecting portion 9b each form a right angle, but the connecting portion 9b and the connecting portion 9c form a right angle. The angle can be adjusted by the amount that the head 23 of the connecting portion 9c can swing within the U-groove portion 20b. That is, the angle α formed by the connecting portion 9b and the connecting portion 9c is such that the upper half of the U groove portion is
It can be freely adjusted between the angle X formed by c and the angle Y formed by the lower half (X≧α≧Y).
Also, the angle β between the connecting portion 9c and the connecting portion 9d
(FIG. 10) can be adjusted by rotating the connecting portion 9d around the bolt 26.

Once the necessary adjustments have been made, the bolts 26 are tightened to immovably connect the connecting portions 9a to 9d.
The connection parts 9b and 9c have a wide area and are not in contact with each other.
Even if they are connected in the state shown in the figure, they can have sufficient strength as a tent frame by tightening the bolts 26. As described above, since the angle between the connecting parts 9b and 9c and the angle between the connecting parts 9c and 9d can be adjusted, the decorative tent frame universal joint of the present invention can be used at various heights with one type of joint. Frame members can be joined at the corner portions of a frame having a depth and depth.

In addition, in the illustrated example, the integrated connecting portions 9a,
Two U-groove portions 20a and 20b are provided in the connecting portion 18 of 9b. For this reason, the same universal joint can be used with a different U-groove overlapping the head of the connecting part 9c, and the cut 2
By simply changing the direction in which the flat plate part 28 is inserted into 4,
It can be used on either the left or right side of the frame 3a. That is, in the illustrated example (see FIG. 11) having the connecting portions 9a and 9b of the same shape and size, the head 23 of the connecting portion 9c is overlapped with the U groove portion 20b, and the flat plate portion 28 is inserted into the cut 24 from the left. When inserted, it can be used as the universal joint of section a in FIG.
0a, insert the flat plate part 28 into the cutout 24 from the right, and insert the inclined frame material 8 into the connecting part 9a and the connecting part 9b.
If the lower frame member 10 is connected to the lower frame member 10, it can be used as a universal joint shown in section b in FIG. However, if two types of symmetrical types are used, it is sufficient to provide one U-groove 20a or 20b in the connecting portion 18.

Since the universal joint for the frame of a decorative tent of the present invention is constructed and used as described above, it can be manufactured at a low cost with a simple structure, and the frame can be easily assembled. It has a great effect on reducing the cost of frames due to general use.
