Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the disclosure of an extremely novel and effective backpack that is expected to be used for a variety of purposes.

One of the anticipated main purposes of the present invention is to use a device for attaching and detaching the auxiliary frame to a normal backpack carrier for use in various conveyance means, such as carry on one's back as a backpack, conveyance as a tongue force by gripping, etc. The purpose of this design is to enable it to be effectively used as a transport device.

Next, one of the other main objects anticipated in the present invention is to make it possible to effectively rest or sleep in a state separated from the ground by a required width as a simple bed or the like at the same time as such a transportation means. It was placed at the point.

Furthermore, one of the other main objects anticipated in the present invention is that by providing extermination means or extermination means in backpacks, it can be particularly effective for mountain climbing and other outdoor transportation. It was placed in

Next, one of the other main purposes anticipated in the present invention is to make it possible to use the backpack as a two-wheeled hand-carried vehicle on flat ground by attaching appropriate auxiliary wheels to the backpack. It was put in place at the point where

Furthermore, one of the other main objects of the present invention is to make effective use of the extendable handle of the backpack, so that it can be used appropriately as a prop for hiking in the mountains in winter. The aim is to make it possible.

Furthermore, various other objects contemplated by the present invention will be made clear from the following description, and the present invention intends to achieve appropriate and purposeful effects of such characteristics. The outline of the structure is as follows: A pair of left and right stands are used to connect the wheat culms to be used, and a mount is protruded from the bottom of the backpack frame toward the rear. In the configuration of the backpack carrying frame, an auxiliary frame is removably attached above the wheat culm of the backpack frame, and the auxiliary frame is fitted onto or fitted over the wheat culm to become telescopic and interconnected, and the auxiliary frame has an upper end portion. A protruding eaves portion is formed on one side, and handle portions are protruded from the lower use front of both sides of the backpack frame and from both sides of the auxiliary frame in the direction opposite to the eaves portion. In view of this, considerable design changes were planned in conjunction with the above-mentioned configuration outline.

The details of the present invention will be described below with reference to a typical embodiment shown in the drawings. Reference numerals 1 to 1 represent wheat culms that are used in left and right pairs, and are provided with pipe materials having the required length dimensions. The wheat culms 1 to 1 are connected by the horizontal rods 2 to 2 to form the basic frame of the backpack, and the wheat culms 1 to 1 are connected from the approximately central position of the upper horizontal rods 2 in this basic frame. Attaching backpack bands 3 to 3 toward the lower position of use of the wheat culms 1 to 1, and protruding a pedestal 4 toward the side after use from the lower ends of the wheat culms 1 to 1, and connecting the free ends of the pedestals 4, The mounting plate 6 has a planar shape and has mounting plates 6 to 6 for a pair of left and right auxiliary wheels 5 to 5 hanging downward from the bottom surface of the pedestal 4.

Next, the wheat stalks 7 to 7 of the auxiliary frame, which are used in an upright position by being removably inserted into the wheat stalks 1 to 1 of the frame, are connected as appropriate to the basic frame of the previous backpack using horizontal rods 8 to 8. At the same time, an eaves frame 9 is protruded from one side of the upper end of the wheat stems 7 to γ in a planar shape, and is covered with a PVC sheet 10 or the like. .

Furthermore, a relatively strong sheet material 1 is provided between the wheat culms 1 to 1 placed on the basic frame and the wheat culms 7 placed on the auxiliary frame.
1 to 11 are horizontally extended, and an auxiliary sheet 12 is placed on the auxiliary frame from the upper horizontal rod 8 position of the wheat stem 7 toward the mounting direction of the basic frame and extends over the installation width of the wheat stems 7 to 7. , and the free end of this auxiliary sheet 12 is adapted to be engaged with the horizontal rods 2-2 of the wheat culms 1-1 in the basic frame so as to be adjustable at any time.

Next, a handle ring 13 is integrally attached to the basic frame, located in the opposite direction to the attachment of the pedestal 4 of the wheat stem 1, and a similar handle ring 14 is attached to the auxiliary frame, located in the opposite direction to the attachment of the eaves frame 9. This is how it was done.

The present invention has a unique configuration on paper, in particular, the basic frame and the auxiliary frame can be separated, and the state of engagement between them can be freely changed, especially the length of use can be changed. - Considering the change in the engagement position of the spread sheet etc. due to the expansion and contraction of the frame, the structure of the eaves frame 9 and the setting direction of the eaves frame 9 can be changed freely forward and backward, and By providing the handle rings 13 and 14, the frame can be expanded and contracted and used as a tongue or a support. The concrete effects of the above-mentioned rope characteristics are made possible by the fact that a simple bed can be constructed as a pillar, and by the installation of auxiliary wheels 5, it can be made into a two-wheeled hand-transported vehicle.

That is, in the backpack according to the present invention, when used as a regular backpack, the length of the rod part that supports the luggage can be adjusted freely to match the amount of luggage, and the eaves frame 9 is The structure is designed to avoid direct sunlight or rainwater, and if necessary, the eave frame 9 can be directed toward the cargo to protect the loaded cargo.

Next, when using other conveyance means, especially as tongue force, after fully stretching and fixing the wheat culms 7 to 7, the auxiliary sheet 12 is spread out and used by holding the handle rings 13 and 14. In addition, when used as a toga, especially for rescue of people in distress, the handle rings 13 and 14 are made of willow, and the pedestal 4 and eaves frame 9 are towed as gripping operation parts.Furthermore, it can be used as a bed. The use of was also made possible by a similar method.

In addition to such multi-purpose use, the backpack according to the present invention is designed to use a push two-wheeled vehicle as its basic transportation means, and is capable of changing the mode of transportation at any time on level ground.

As stated on paper, the present invention is concerned with the provision of a highly novel and effective backpack that is effectively guaranteed to be used for a variety of purposes.
