Description

[Detailed description of the invention] Industrial application field This invention relates to the structure of a tent.

This invention relates to an improvement in the structure of the frame-engaging cylindrical part that inserts and engages the frame, especially in tents that are set up by a frame. The purpose is to keep it open at all times.

BACKGROUND TECHNOLOGY In a conventional tent that is mounted externally using a frame, the entire frame-engaging cylindrical portion, including its insertion opening, is flat, provided along the outside of the tent where the frame is to be attached. It was designed to be folded.

Problems to be Solved by the Invention As mentioned above, when trying to insert and engage the frame into the frame-engaging cylindrical part that has been folded flat,
This insertion port must be opened, especially when setting up a tent in winter or in extremely cold regions, when the insertion port of the frame-engaging cylindrical part is frozen in its folded state and you open it. have difficulty. In addition, in such cases, the difficulty of setting up the tent increases as people generally wear cold weather equipment such as gloves, and depending on the length of time it takes to set up the tent, it can become even more difficult. It is also assumed that In addition, even in seasons or areas other than the winter or extremely cold regions mentioned above, rapid weather conditions can suddenly change, especially when exposure to wind and rain occurs before construction, and the rainwater forms a plate, requiring emergency construction. One of the factors that impede construction occurs when the frame-engaging cylindrical portion is maintained in its folded state due to inertia.

In general, tents are folded to be as compact as possible when not being set up, and are tightly inserted into a container such as a storage bag. It is also folded in a compacted state, and due to moisture infiltration from rainwater etc., it often assumes the form of a single plate, and it retains this form even when it is frozen or set up due to inertia. Often maintained.

This invention was developed to solve the above-mentioned inconvenience, and the frame insertion opening of the tent-engaging cylindrical part is always kept open.

Means for Solving the Problems This invention at least solves the problem when the tent is folded tightly and stored in a predetermined container such as a storage bag when storing the tent other than when setting it up. A hard material with strong mechanical elements that does not lose its shape, such as rubber, synthetic rubber, synthetic resin, or metal as necessary, is used as the material, and the outer periphery of the frame to be inserted is circular and the outer circumference is a line. A rectangular pipe-like body with a shape on the inner circumference that can be slidably engaged with contact forms the end of the frame-engaging cylindrical part provided at the position where the frame of the tent is planned to be stretched, and The structure is such that it remains open at all times so that a frame can be inserted even when the case is in use.

Embodiment Next, an embodiment of this invention will be described with reference to the drawings.A frame having a circular cross-sectional shape is installed along the frame extension points 2, 2', and 2'' set at desired positions on the outside of the tent 1. The frame-engaging cylindrical portion 3, 3', 3'' through which the cylindrical portion 5 is inserted is formed by a sutured configuration;
A length range of about 3 cm to 5 cm at the ends of the frame-engaging cylindrical portions 3, 3', 3'' is covered with a material such as hard rubber, synthetic rubber, synthetic resin, or metal as necessary. , the outer periphery of the frame 5 having a circular cross section is always open, with pipe-like bodies 4, 4', 4'' having a rectangular inner periphery that can be slidably engaged by a plurality of line contacts in the longitudinal direction of the frame 5. It is configured so that the state is maintained.

The pipe-like bodies 4, 4', 4'' are formed with a triangular cross section as shown in FIGS. 3 and 4, but the shape of the inner periphery is not limited to the triangular shape. For example, it is easier to insert a rectangle, pentagon, or polygon if it has a relatively small number of angles, such as a hexagon at most.
Regarding the material of the pipe-shaped bodies 4, 4', 4'', it is possible to fold the tent 1 to store it, and also press it into a container such as a specific storage bag. It has strong mechanical elements that do not cause disadvantages such as deformation and loss of shape, and is made of a material such as hard rubber, synthetic rubber, or synthetic resin, or a metal material if necessary.

Function: This invention configured as described above has the frame-engaging cylindrical portions 3, 3', 3'' may be maintained in a flat and pressed state due to inertia in the folded state when stored, but the pipe-shaped body forming the end of the frame-engaging cylindrical part 3, 3', 3'' 4,
4' and 4'' have their end insertion openings open at all times due to their material characteristics, no matter what condition they are in.
There is no need to open the insertion port to insert the frame 5, and the distal end of the frame 5 can be immediately inserted through the opening.

As described above, the inner periphery of the pipe-shaped body 4 into which the frame 5 is inserted and engaged has a rectangular configuration, so the connection state between the outer periphery of the frame 5 and the inner periphery of the pipe-shaped body 4 depends on the number of squares on the inner periphery. There is a corresponding number of line contacts, and therefore, the areas other than the contact points are facing the air gap, so
The contact resistance during insertion and sliding allows easy sliding insertion, unlike contacting the entire outer periphery of the frame 5, and the cross-sectional area is much larger than that of the frame 5. Of course, this means that the pipe-shaped body 4 made of water-free material will not be deformed even by infiltration of rainwater regardless of the season, and in particular,
Even in the severe cold of winter or in extremely cold conditions at high places, even if condensation occurs when the pipe-shaped body 4 and frame 5 come into contact with extremely cold outside air, which is different from the atmosphere when stored, the contact area By reducing the amount of water, there is no risk of a phenomenon in which insertion is impossible, and the larger the opening area, the lower the probability that the opening will close due to freezing.

Since the pipe-shaped body 4 is thus open under any conditions, it is not necessary to take the trouble of providing an opening means as in the past, and it is sufficient to simply support the pipe-shaped body 4 with one hand for the insertion operation of the frame 5, and to hold the frame 5 with the other hand.
This allows the operator to concentrate solely on the insertion work, and can easily perform these tasks while wearing gloves. This is particularly effective in allowing one hand to be used relatively freely in extreme conditions such as bad weather or extreme cold, which occur throughout the year.

However, once the frame 5 is engaged with the opening of the pipe-like body 4, all that is left is a pressing operation, and the work of passing the pipe-like body 4 is also easy because the inner periphery is formed into a rectangular shape. Although the inner cavity has a cross-sectional area much larger than the cross-sectional area of the frame 5, the contact form is a line contact, so that the insertion operation can be easily performed with very little resistance due to contact sliding.

In this way, the pipe-shaped body 4 is characterized by its great effect in that it contributes to the easy operation of setting up the tent as an introduction section for the frame-engaging cylindrical part 3.
