Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tent frame that is easy to store and assemble.

(Prior art and its problems) Tents in which curtain cloth is supported by one or more rod-shaped poles are widely used, but in conventional tents, each pole is formed as an independent long rod. Therefore, it is bulky when stored, inconvenient to carry, and difficult to assemble.

In order to improve this, a pair of elastic frames are constructed by bending a linear frame that is hard, tough, and flexible and can be divided into arcs, and intersecting the blades to form a diagonal line at the top. By providing a pair or more of the above-mentioned curved frames, fitting both ends of the curved frame into the bottom holes of the bag-like curtain cloth, stretching the curtain cloth bottom cloth, and hooking the hanging tool provided with the curtain cloth on the above-mentioned frame. A tent that forms a living space has been proposed (Utility Model Application No. 127529/1983), but this tent had the following problems.

Because one frame is long (e.g. 4m),
When pitching a tent on a slope, such as on a snow-covered mountain course, there is not enough space to assemble a long frame, which can be dangerous due to wind pressure.

Since the frames are not connected to each other, each frame moves independently, and since the curtain cloth is only hung on the frame, it is unstable against external pressure and the shape of the tent changes easily, creating a feeling of anxiety for the user. give.

When a long frame is elastically deformed, the curvature of each short pipe that makes up the frame is constant,
Since the height of the frame is automatically determined when the positions of both ends of the long frame are determined, it is not possible to widen the living space in the direction of the zenith of the tent.

(Purpose of the Invention) The present invention has been made in view of the above circumstances.The frame is easy to assemble even in a small space with unstable footing, has a large resistance to external pressure such as wind pressure when pitching a tent, and can be used as needed. The purpose of the present invention is to provide a frame for a tent that can raise the zenith.

(Structure of the Invention) The frame for a tent according to the present invention has a through hole bored in the side part, and has a top member that is placed at the top of the tent when the tent is pitched, and is attached radially to the top member in pairs. The pole is composed of a plurality of short cylindrical bodies connected in series and detachable from each other, and an elastic string passing through the inside of these cylindrical bodies and connecting the plurality of cylindrical bodies. , and is characterized in that two poles forming a pair with the top member in between are connected by a single elastic cord inserted through a through hole in both poles and the top member.

(Embodiment) Below, the embodiment shown in the drawings will be described. FIG. 1 is an external view showing the state of use of a tent frame according to the present invention. Paul 3,3
It consists of a, 3b, 3c... The top member 2 is placed at the top of the tent, and consists of an upper member 2a and a lower member 2b, both of which are inserted into a recess 5 provided in the core of the upper member 2a, as shown in FIG.
They are integrated by fitting a protrusion 6 provided on the core of the two. The top member 2 is provided with a locking device 4 for securing its upper member 2a and lower member 2b. That is, a pair of screw holes 7 for bolts are provided on the upper surface side of the lower member 2b, and a pair of arcuate elongated holes 9 are provided in the upper member 2a at positions corresponding to the screw holes 7. ing. A bolt 10, which vertically passes through elongated holes 9, 9 of the upper member 2a, is screwed into the screw holes 7, 7 of the lower member 2b. When this bolt 10 is loosened, the upper member 2a can be freely rotated by the length of the elongated hole 9 relative to the lower member 2b, but when the bolt 10 is tightened, both can be rotated freely. Fixed. The locking device 4 is not limited to the one shown in the drawings, but any other suitable device can be used as long as it can secure the upper member 2a and the lower member 2b.

A through hole 11 that penetrates in the diametrical direction is provided in the side portions of the upper member 2a and lower member 2b that constitute the top member 2.
is drilled. The through hole 11 is formed as an enlarged diameter part 11a into which the pole 3 fits up to a certain depth from the entrance part, and the core part is formed as the through hole part 11 with a smaller diameter than the enlarged diameter part 11a.
It becomes b. The through hole 11 is inclined at an angle α of 5 to 15 degrees with respect to the horizontal plane so that the inlet side is downward. This angle of inclination α may be appropriately selected depending on the height of the living space and the difficulty of coming off when external forces such as wind pressure are applied, and may be horizontal in some cases.

The pole 3 is formed by connecting a plurality of short hollow cylindrical bodies 15 in series. The short cylinder 15 has a through hole 1 in its core.
7, and a joint 19 is fitted to one end thereof. The joint 19 has a distal end 19a that is connected to the short cylindrical body 15.
It is fixed to the short cylindrical body 15 by caulking P in a state of protruding from the cylindrical body 15. Tip 1 of this joint 19
9a fits into the opening of the adjacent short cylindrical bodies 15 on the side without a joint, and joins the short cylindrical bodies 15 together.
Note that a through hole 19b is bored in the core of the joint 19.

A stopper 20 is fitted to the tip of the short cylinder 15 located at the lowest end of the pole 3. An end portion of an elastic string 21 is fixed to this plug 20, and this elastic string 21 is connected to the inside of each short cylinder 15 arranged in series constituting the pole 3 and to the joint 19. reaches the top member 2 through the through hole 19b;
It is similarly inserted into the pole 3 on the opposite side through the through hole 11b of the top member 2. opposite pole 3
The distal end of the elastic cord 21 inserted through the pole is fixed to the stopper 20 of the short cylinder 15 at the lowermost end of the pole. That is, the elastic string 21 passes through the interior of a pair of poles 3, 3 provided in the diametrical direction of the top member 2, is stretched to some extent, and is fixed at the tips of both poles. The short cylindrical bodies 15, 15, . . . are biased in the direction of joining together. Short cylinder 15 at the upper end of the pole 3
The upper end portion of the top member is fitted into the enlarged diameter portion 11a of the top member. As the elastic string 21, a rubber string, a coil spring, etc. can be used. In addition, the short cylindrical body 1
5 can be formed of a metal pipe such as an aluminum pipe, a resin pipe, etc., and the top member 2 can be formed of metal, synthetic resin, etc.

Note that, similarly to the upper member 2a, the lower member 2b is also provided with a pair of poles 3 formed by connecting a plurality of short cylindrical bodies 15, 15, . . . in series in the diametrical direction. The poles 3, 3 (A, B) provided on the upper member 2a
) and the poles 3, 3 provided on the lower member 2b.
(C, D) can be arbitrarily adjusted by mutually rotating the upper member 2a and lower member 2b, but normally it is 76 degrees β and 104 degrees.
An angle of the order of degrees β′ is adopted.

Next, when storing this tent frame 1, the uppermost short cylinder 15 is removed from the top member 2 and each short cylinder 15 is separated. When separated in this way, the short cylindrical bodies 15, 15, . This makes it convenient to store and carry. Even in this state, the group of short cylindrical bodies 15 constituting the pair of poles 3, 3 and the upper member 2a or lower member 2b are connected to one elastic string 2.
1, reassembly is easy and these parts will not become separated or lost.

The curtain cloth 25 of the tent is attached to and supported by the poles by hanging tools 27, 27, . . . . curtain cloth 2
5 may be attached to the frame in other ways.
In the figure, 25a is a doorway, and 25b is a window.

In the illustrated tent frame 1, two poles 3 are provided on each of the upper member 2a and the lower member 2b, but three or more poles may be provided on each member. Alternatively, the top member 2 may be formed as a single member instead of being divided into an upper member 2a and a lower member 2b as in the illustrated example, and a plurality of poles may be attached radially to this member.

In the illustrated example, one tent is set up using one set of tent frames 1, but as shown in FIG. By connecting the two, it can also be used to pitch a tent with a desired length.

(Effects of the Invention) As explained above, the tent frame according to the present invention includes a pole for supporting a curtain cloth, which is constructed by joining a plurality of short cylinders in series, and is constructed in this way. Since a plurality of poles are connected to each other by the top member, it is easy to assemble, convenient to store, and has excellent strength. Furthermore, since the pair of poles attached to the top member are connected to each other by a single elastic cord passing through the inside of the top member, the parts are not separated and assembly is extremely easy. Since the top member is composed of an upper member and a lower member that are mutually rotatable, it is possible to freely adjust the relative angle in plan view of the plurality of poles that intersect at the top.
It has become easier to change the conditions of use of the tent. Since the strain applied to the pole can be reduced, the selectivity for the material of the pole can be increased, and it can be made economically superior. Note that it is also possible to change the volume of the tent by increasing or decreasing the number of short cylindrical bodies that constitute the poles.
