Description

[Detailed Description of the Invention] The present invention relates to a tent in which the tent area can be opened and closed like an umbrella.

This kind of tent is disclosed in Japanese Utility Model Application No. 54-60929, but in that case, the raising and lowering of the inner cylinder to which the umbrella rib etc. are attached is directly linked to the opening and closing of the umbrella, which causes a lot of burden. , counterbalance etc. are also required,
The operation is slow, and the amount of vertical movement of the inner cylinder is also large.

The present invention is intended to solve the above-mentioned problems, and its purpose is to provide a tent that can be opened and closed easily, quickly, and lightly.

In order to satisfy the above object, the present invention is constructed as follows.

That is, the present invention fixes a base 4 on which tensioning rods 3, 3, etc. are pivoted so as to be able to open and close radially on top and bottom pipes 2 that are loosely inserted into a base pipe 1 standing on the ground, and a tent base 5 is fixed on top and bottom pipes 2 that are loosely inserted into a base pipe 1 standing on the ground. The tension rods 6, 6, . is attached to the operating tube 7 that is loosely inserted into the base tube 1, and a connecting strip 8 has one end fixed to the lower part of the upper and lower tubes 2.
a, 8e are hung around pulleys and gears provided on the upper part of the base pipe 1, and then the other ends are fixed to the operating tube 7, so that the operating tube 7 and the upper and lower tubes 2 are connected. It is an umbrella-shaped tent. In the embodiment shown in FIGS. 1 to 4, a wire rope 8 is used as a connecting thread.
The example shown in FIG. 5 shows a transmission mechanism 8 using a chain 8e as a connecting line, in which the operation cylinder 7 is connected to the lower end of the upper and lower pipes 2.
The modification shown in Fig. 6 is a wire rope 8 as a connecting thread.
In addition, a rack and pinion transmission mechanism 8 is used. However, in the example shown in FIGS. 1 to 4, a handle 9 is provided on the operation barrel 7, and by holding the handle 9 with the hand and pushing it down, the wire rope transmission mechanism 8
The upper and lower pipes 2 are raised through the tent, and the tent is closed by a tension rod 6 and a tension rod 3. Reference numeral 10 is a stopper handle for fixing the operation tube 7.

Next, in the chain transmission mechanism 8 shown in FIG.
By pulling and turning the sprocket 8c, the sprocket 8c is rotated, and the upper and lower pipes 2 are operated by the chain 8e. Incidentally, the sprocket 8c may be rotated by an electric motor.

In the one in Figure 6, the rack 8f is connected to the shaft 8g of the pulley 8b.
The rack 8f is fixed to the hollow support 2, and the rope 8a is connected to the pulley 8b.
Hook one end to the operating tube 7 and the other end to the hollow support 2, turn the pinion 8h to raise the upper and lower tubes 2 via the rack 8f, and connect the operating tube 7 to the operating tube 7 via the rope 8a.
The tent was lowered by its own weight to close the tent.

In each figure, reference numeral 14 denotes a spring for tensioning the tent fabric, which is inserted into the telescopic tube 15 inserted into the hollow tensioning rod 3, and its one end is attached to the telescopic tube 15 and the other end is attached to the tensioning rod 3. A ring 17 of the tent fabric 5 is hooked onto a hook 16 provided at a hook 15, and the tent fabric 5 is made to be tensed when unfolded by the action of a spring 14. 18
is a fixture for the tension rod 6, which is provided at the upper end of the operation tube 7, and one end of all the tension rods 6, 6, . . . is pivoted by a pin 19,
And the other end is attached to the middle part of the tension rod 3, 3... with pin 1.
It is pivoted by 9'. Reference numeral 20 denotes a pivot pin of the tensioning rod 3 to the base 4, and 21 and 21' denote receiving rings of the fixture 18, which are fixed to the operating cylinder 7 at the top and bottom of the fixture 18 by screws 22 and 22'. 23 is the fixed concrete of the base pipe 1, 24 is the tightening rope hanging ring, 25, 26
1 shows the upper and lower pipes 2, the wires to the operation tube 7, and the chain mounting hardware. The shape of the tent area 5 may be a normal umbrella shape as shown in FIG. 7a, or may be square as shown in FIG. 7b, and various other shapes can be selected.

Since the present invention has the above configuration, it is possible to manually operate the operation tube 7.
The tent can be closed by pushing down or turning the sprocket or pinion manually or by a motor, and opened by pushing up or turning the sprocket or pinion in the opposite direction.

That is, in the present invention, the upper and lower tubes 2 and the operating tube 7 are connected via pulleys and gears with connecting strips 8a and 8e, so when the operating tube 7 is raised, the upper and lower tubes 2 are lowered, and the upper and lower tubes 2 are attached to the upper and lower tubes 2. The tension rod 3 opens, and the weight of the tent opening/closing part and the upper and lower tubes 2 act to open the tent, so the force required for the opening operation is small.
Moreover, since the operation tube 7 rises quickly, the amount of elevation of the upper and lower tubes 2 is also reduced. When closing the tent, the operation tube 7 is lowered, but this is also done easily because the tension rod 3 and the tent fabric 5 are loaded, which acts to push up the upper and lower tubes 2. Therefore, compared to conventional tents, it has the practical benefit of being able to be opened and closed more quickly and easily. In particular, according to the present invention, the upper and lower tubes move up and down when opening and closing the base tube 1 without requiring the length corresponding to the radius of the tent, so it can be opened and closed smoothly without taking up much space.
