DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple assembly type tent which is installed outdoors at events such as bazaars, athletic meet, school festival, and short-term events.

[0002]

2. Description of the Related Art Such prefabricated tents are ideal for overcoming rain and direct sunlight at various outdoor events.
Widely used. This assembled tent is composed of a frame (pipe) serving as a framework and a sheet attached to the frame to serve as a roof of the framework. The two-flow type shown in FIG. 8 and the single-flow type shown in FIG. 9 are generally used. In either type, the frame includes a frame portion 81 serving as a support, a frame portion 82 serving as an eave, a frame portion 83 serving as a ridge, and a frame portion 84 which is obliquely hung to connect the eave and the ridge. Having. After assembling this frame 80 (or in the middle of assembling), the sheet 90 is put on the skeleton, a rope (not shown) attached to the sheet 90 is tied to the frame portion 82, and the sheet 90 is fixed to the frame 80. I have.

[0003] Further, in order to increase the stability of the tent, the frame portion 81 is fixed to the ground with a pile and a rope.

[0004]

However, since this kind of assembled tent is installed outdoors, the seat 90 may be blown by strong winds (especially gusts). Even if the frame portion 81 is fixed with a pile and a rope, the sheet 90 soars into the air together with the frame 80, and sometimes the frame 80 hits a person and injuries occur. In particular, the total weight of the entire frame 80 may be close to 100 kg, and if such a heavy frame 80 falls in a crowd, serious damage may be caused.

[0005] In order to prevent this, the frame portion 81 of the column is required.
Must be firmly fixed with concrete foundation. However, events such as bazaars, athletic meet, school festival,
In a prefabricated tent used as a simple roof for short-term events, building concrete foundations requires delivery time, cost,
It is physically impossible to clean up after the event, and the current situation is that a pile is driven into the ground. For this reason, the sheet 90 and the frame 80 fly by the gust and the accident that the person is injured is not stopped.

The present invention has been made in view of such a problem, and an object of the present invention is to provide an assembling tent which can prevent an accident due to a drop of a frame without the frame flying even in a strong wind.

[0007]

In order to achieve the above-mentioned object, the present invention relates to a prefabricated tent comprising at least a frame which forms a framework of a tent having eaves, and a sheet which is attached to the frame to form a roof of the framework. Wherein the sheet is provided with a hook which is detachably fitted to a frame portion corresponding to at least the eaves of the skeleton, and the hook is formed so as to be naturally released from the frame portion by a wind speed of a predetermined value or more. It is characterized by the following.

In this assembly type tent, the seat is attached to the skeleton by fitting the hooks of the seat to the frame portion which becomes the eaves of the skeleton. When the strong wind exceeds a predetermined speed, the hook naturally comes off the frame portion, the sheet loses its support, and only the sheet is blown off by the strong wind. Since the seat is much lighter and softer than the entire frame, even if the seat falls and hits a person, injury is unlikely.

That is, in the assembled tent according to the present invention, the frame remains as it is even when a strong wind blows, so that the frame does not fly with the sheet, and no injury is caused by dropping the frame.

[0010] In the present invention, the hook attached to the seat has a function of coming off naturally from the frame portion by a strong wind of a predetermined value or more, and it is preferable that the hook has a C-shape having elasticity.

Although the predetermined value of the wind speed in the present invention cannot be specified unconditionally depending on the size of the tent, that is, the size of the seat, etc., as a rough guide, the hook is located outside the frame portion up to the wind speed of 15 m / s. 17m / s wind speed
At this time, the hook is set to be naturally released from the frame portion. Of course, for example, a wind speed of 40 m / s
In the event of a catastrophic gust of wind, the hook immediately comes off the frame.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to embodiments. It should be noted that the assembled tent of the present invention is characterized by a hook attached to a seat, and a frame composed of a frame may be the same as a conventional one shown in FIGS. 8 and 9. explain.

FIG. 1 is a plan view of a hook portion of the seat, and FIG. 2 is a side view thereof. However, hooks (described later) are omitted in FIGS. 1 and 2. On the back side of the seat 90, the long piece 1 is attached to a portion close to the frame portion 82 corresponding to the eaves of the frame so as to be along the frame portion 82. Since the skeleton shape of the entire frame portion 82 of the eave is a quadrangle, the long piece 1 is provided in an annular shape accordingly. The long piece 1 is made of the same material as the sheet 90. For example, when the sheet 90 is made of polyester canvas coated with vinyl chloride resin to have a waterproof function,
It is made of the same material as the sheet 90, and is formed by bending it as shown in FIG. The upper part of the long piece 1 is a sheet 9
The long piece 1 is firmly fixed to the sheet 90 by the welded portion 3.

A reinforcing rope 10 having a diameter of, for example, 4 mm is passed through the lower part of the long piece 1. The upper part and the upper folded part of the rope 10 are formed so that the rope 10 does not come off and the folded part is originally formed. The threaded portion 11 is provided so as not to return. A strip tape 20 that is difficult to break is firmly fixed to the long piece 1 by a swage 21.
The band tape 20 is made of, for example, a 1 mm thick nylon tarpaulin.

A rectangular connection fitting 30 is suspended from the band tape 20, and an engagement shaft 31 slidable along the connection fitting 30 is passed through the connection fitting 30. Engagement shaft 31
Has an insertion hole 31a at both ends, and the connection fitting 30 is inserted into the insertion hole 31a. The surface of the engagement shaft 31 is knurled.

A hook 40 having a shape as shown in FIG. The hook 40 has a C-shaped part 4 for receiving a frame part 82 corresponding to a skeleton eave.
1 and an inverted U-shaped part 42 for receiving the engagement shaft 31. The part 41 and the part 42 are formed integrally.
The hook 40 is made of, for example, polypropylene, and has elasticity so that the portion 41 can be detachably fitted to the frame portion 82. This hook 40 has a predetermined value (1 in the previous example).
7 m / s) or more so as to naturally deviate from the frame portion 82.

FIG. 4 is a plan view showing a state in which the hook 40 is hooked on the engagement shaft 31. The hook 40 can be easily set on the connection fitting 30 by hanging the portion 42 on the engagement shaft 31. In this state, not only the hook 40 but also the connection fitting 3
0 can be moved like a pendulum. Parts related to the hook 40 (the hook 40, the connection fitting 30,
An appropriate number of the engagement shafts 31 and the band tapes 20 are provided at regular intervals on the long piece 1.

Next, the operation of the assembled tent having the seat 90 provided with the hook portion having the above structure will be described.
This will be described with reference to FIGS. The tent may be any of the two-flow type shown in FIG. 8 and the single-flow type shown in FIG. In any type of tent, at the time of assembling, a frame composed of a frame 80 is assembled, a sheet 90 is put on the frame, and the hooks 40 of the sheet 90 become eaves.
2 is fitted from the outside. Since the hook 40 has appropriate elasticity, it is easy to fit the C-shaped portion 41 by lightly pushing the portion 41 into the frame portion 82. When all the hooks 40 are fitted to the frame portion 82, the attachment of the seat 90 to the framework is completed.

After the seat 90 has been mounted, the seat 90 is in a normal state as shown in FIG. In this normal state, the wind speed 15
Even if the wind of m / s or less blows, the hook 40 does not come off the frame portion 82, and the seat 90 maintains the function as the roof of the tent.

Here, when a strong wind of 17 m / s or more is blown, and especially when the sheet 90 is blown up by strong wind from the inside, the force of the arrow F is applied to the sheet 90 as shown in FIG. Accordingly, the connection fitting 30 is pulled in the direction of the arrow, and the hook 40 rotates in the direction of the arrow.

If the strong wind stops in the state of FIG. 6, the normal state of FIG. 5 is restored.
As shown in FIG. 7, the hook 40 is further pulled by the connection fitting 30 and immediately comes off the frame portion 82.
As a result, only the sheet 90 is blown off by the strong wind, the skeleton remains, and there is no danger that the skeleton is blown off together with the sheet 90. Therefore, there is no risk of the flying frame hitting a person and causing injury.

Next, the results of a strong wind test performed on the assembled tent will be described. The tent was of the two-flow type shown in FIG. 8, the size of the sheet 90 was 1.5 × 2.0 (interval), and the frame was composed of a frame 80 corresponding to the size.
The tent was set up on the outdoor ground. However, the frame portion 81 of the frame support is not fixed using a pile and a rope. Then, the air was blown toward the tent using a fan having a maximum wind speed of 30 m / s (two units are used only in a destructive gust). The wind speed was measured with an anemometer.

According to the test results, during normal use, that is, when the wind speed was up to 15 m / s, the hook 40 did not come off the eaves frame portion 82 of the skeleton.

At a wind speed of 17.5 m / s, which is the limit at which the hook 40 comes off the frame portion 82, the hook 40 starts to come off from the center of the frame portion 82 to the end.
However, the sheet 90 was not blown away from the framework.

Further, when the wind speed was increased and a catastrophic gust, that is, at a wind speed of 40 m / s, all the hooks 40 were immediately disengaged from the frame portion 82, and the sheet 90 was blown away from the framework. However, the frame 80 constituting the skeleton was not allowed to fly, nor did it float from the ground. In addition, the frame 80, the sheet 90, the hook 40, and the like were not damaged.

Thus, according to this assembled tent,
The hook 40 is detached from the frame portion 82 by a wind speed equal to or greater than a predetermined value (17 m / s), and only the sheet 90 is blown off by strong wind, so that personal injury and property damage due to the drop of the frame 80 can be prevented.

In addition to this effect, in this prefabricated tent, the seat 90 can be attached to the frame portion 82 by fitting the hook 40 to the frame portion 82, and the seat 90 can be easily removed. The time required for attaching and detaching the seat can be considerably reduced as compared with the conventional tent for connecting the seat to the frame portion 82. That is, at the time of attachment, if the hook 40 is lightly pushed in from the outside of the frame portion 82, the hook 40 fits into the frame portion 82,
At the time of removal, the hook 40 is easily detached from the frame portion 82 by slightly tapping the sheet portion slightly above the hook 40 from the inside of the seat 90 toward the outside.

As a result, the size of the sheet 90 is 1.5 ×
In the case of 2.0 (between), in the conventional tent fixed with a rope, it took about 7 minutes to attach the sheet 90 and about 3 minutes to remove the sheet 90. The time is about 40 seconds, the removal time is about 15 seconds, and the time can be greatly reduced to about 1/10 or less.

In the above embodiment, the hook 40 is provided along the frame portion 82 corresponding to the skeleton eaves. However, the hook 40 is provided along the frame portion 83 corresponding to the ridge and the oblique frame portion 84. Is also good.

[0030]

As described above, according to the prefabricated tent of the present invention, when the wind speed exceeds a predetermined value, the hook naturally comes off from the frame portion corresponding to the eaves of the frame, and only the sheet is blown off by the strong wind. Since the frame is configured to remain as a frame, the following effects can be obtained. (1) Disasters such as personal injury and property damage due to falling of the frame can be prevented. (2) The deformation of the frame and the breakage of the sheet due to strong wind can be prevented. (3) The time required for attaching and detaching the seat can be greatly reduced.
