Description

  The present invention relates to a portable seat that includes a pole that extends and contracts under a seat, stretches the pole when necessary, stands on a floor, and sits on the seat.

  In a public transport vehicle, if all the seats were filled with people, they had to hold on to the straps and continue to stand.

  When standing in a public transport vehicle without sitting in a seat, physical fatigue accumulates over a long period of time, and frequent use may lead to chronic diseases such as back pain. However, even if you usually carry a chair and cannot sit in a seat in the car, sitting in the chair that you bring can be a nuisance such as obstructing traffic in a narrow car. Carrying a chair itself is bulky and heavy and not very realistic. Therefore, it is intended to solve the above-mentioned problem by simply sitting down and being portable.

  The present invention adopts a structure in which an extendable pole is attached under a seat surface on which a seat can be laid without a backrest. The pole is characterized by being able to expand and contract to your preferred seating surface height, and in the most contracted state, it can be folded under the seating surface so that it can be completely stored, making it easy to carry. When actually used, it is used in such a way that one pole is pulled out, adjusted and fixed at an optimum angle with the seat surface, and then placed on the floor and seated on the seat surface. A rubber anti-slip is attached to the bottom of the pole to facilitate fixing on the floor. The body is balanced by holding the hanging leather inside the car. By adopting the above structure, the above-mentioned problems are solved.

  As described above, the present invention is characterized in that it carries a seating surface in which a folded pole is stored, so that it can be easily carried in a bag or the like. If you are unable to sit on the seat in the car and you have to stand up, take out the seat from the bag, fold it, pull out the stored pole, lean against the floor, and sit on the upper seat. At this time, the seating pole is located between the legs of the person and the seating surface is almost covered with the buttocks of the person, so that the surrounding passengers are not disturbed. In this way, it is possible to improve the usual portability and to rest the waist without disturbing the surroundings even during actual use. If you own this product, you do not have to bother to select the starting station to get on the chair in the car and get on to the next vehicle, and if you can not sit in the car, If you take it out and sit down and you can sit in the car, you can retract the pole, fold it, and store it easily. The present invention makes it possible not only to improve one's own health but also to use time effectively.

Best mode for carrying out the invention

  The seat surface of this portable seat has a structure in which there is no backrest, the buttock is placed, the portion where the center of gravity is applied is formed wide, and the front center protrudes to some extent between both crotch. Although the body is balanced with hanging leather in the car, the pole can no longer be supported when the hips are felt away from the seating surface due to shaking, so that the seating surface is always sandwiched between the thighs to prevent the pole from falling over. It is. Moreover, the back side of the part fixed between the two crotches also serves as a part for folding and storing the pole. The angle of the pole bent part can be adjusted with a gear and fixed with a clasp at the optimum angle for each person. The pole is composed of a plurality of cylindrical cylinders with a length that fits on the seating surface. The pole is structured so that a thin pole can be accommodated in a thick pole, and expansion and contraction is achieved by engaging the thread grooves and threads of the inner and outer poles. Adjust with. By taking these characteristics, the above-mentioned portable seat can be realized.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. 1-4 show an embodiment of the present invention. Fig. 1 is a rear perspective view of the present invention in a seated state, Fig. 2 is a rear view of a seating surface when the pole is folded and stored, and Fig. 3 is a side view of the seated state when the pole is pulled out. FIG. FIG. 4 is a front view in which an office worker actually sits in the vehicle in an embodiment when the present invention is actually used.

  1 to 4, reference numeral 1 denotes a seating surface on which the user sits. In consideration of portability, the present invention does not attach a backrest. In addition, the rear part of the seating surface where the weight is mainly placed with the buttocks is widened in consideration of sitting comfort. In addition, in order to prevent the seat from falling from the buttocks when actually sitting in the car, the structure is designed to project the center of the front of the seat, as shown in the actual use example in FIG. The protruding part 2 is sandwiched between both crotch so that it can be fixed at all times. The protruding portion also serves as a storage space when the pole 3 is folded on the back surface as shown in FIG.

  The pole 3 is composed of a plurality of cylindrical tubes having a length that fits perfectly under the seating surface, and the thick tube 4 can accommodate the thin tube 5. A thread groove and a thread 6 are provided at locations where the inner and outer cylinders are in contact with each other, and the pole 3 can be expanded and contracted by this engagement, and the length can be freely adjusted. 1-4, it is composed of four cylinders. However, the number of the cylinders is not limited to this, and the length of one cylinder is related to the length of the seating surface to be accommodated. The length of the cylinder is set, and the number of cylinders necessary for the height of the seating surface on which the user actually sits may be used. If a large number of cylinders are required, the width of the protruding portion 2 may be expanded to cope with it. A rubber-like anti-slip 7 is attached to the end of the pole 3 in contact with the floor to prevent slipping when sitting.

  2 and 3, the pole comes into contact with the seating surface at the rear surface of the wide part behind the seating surface on which the collar portion is mainly placed. By touching at this position, the weight transmitted from the buttocks can be easily applied directly to the pole. At the place where the pole 3 is connected to the seat surface 1, two gears 8 are attached so as to face each other, and the gear 8 is fixed so as not to rotate with respect to the pole 3. Also, a stop shaft 9 that penetrates the center of the gear 8 and the pole 3 is attached, and the stop shaft 9 is also fixed to the pole 3 and the gear 8 without rotating. As shown in FIG. 2, in this state, the position of the gear 8 is determined so that the pole 3 can be tilted to the protruding portion 2 side, and the stop shaft 9 is passed through the stop bearing 10 on the seat surface. Thus, the pole 3 can freely rotate around the stop shaft 9, but it is necessary to fix the seating surface at an optimal position, so a clasp 11 for fixing the gear 8 is attached. The clasp 11 is also fixed by a clasp retaining shaft 12 and a clasp retaining bearing 13, and the clasp 11 fixed to the retaining shaft 12 can freely rotate with respect to the retaining bearing 13. Here, a spring 14 is inserted between the seating surface and the clasp 11 so that the clasp 11 always presses the gear 8. By doing so, the clasp 11 always presses the gear 8 and the pole 3 continues to be fixed to the seat surface 1. If the clasp release lever 15 attached to the clasp 11 is pulled up in the direction in which the spring 14 is contracted, the pole 3 can be rotated.

  When carrying with the above configuration, as shown in FIG. 2, all the cylinders are screwed in until they become the shortest, the clasp release lever 15 is pulled up, and the pole 3 is stored in the seat surface 1. When the clasp release lever 15 is released, the gear 8 is fixed to the clasp 11 again, so that there is no possibility that the pole 3 jumps out when being carried. If it is in the form stored under the seating surface 1, the product of the present invention feels like carrying around the seating surface and can be carried easily even if it is put in a bag.

  When actually used as a seat, first, the clasp release lever 15 is pulled up and the pole 3 is pulled out from under the seating surface. When the angle between the pole 3 and the seating surface 1 becomes an arbitrary angle that is comfortable to sit on, the clasp release lever 15 is released to fix the pole 3 to the seating surface 1. Next, reverse rotation is applied to the pole 3 which has been shortened by screwing, and each cylinder is pulled out. Since the optimal seating height of each pole 3 is different, the pole 3 is extended to the length suitable for each person, and finally the form shown in FIGS. 1 and 3 is obtained.

  FIG. 4 shows an actual usage example. In the car, lean the pole 3 on the floor and place your waist on the seat 1. In this configuration, the pole 3 is located between your feet, so you won't be bothered by hitting someone else in the car. Since there is only one pole 3, it is not always positioned perpendicular to the floor, and the pole 3 also moves as the vehicle shakes. However, since the rubber-like non-slip 7 is attached to the end where the pole 3 contacts the floor, the pole 3 can be easily fixed on the floor. In this way, it is fixed at the contact point on the floor, but the upper seating surface 1 swings, so that the part 2 that protrudes the seating surface is sandwiched between your two crotch so that the seat does not fall down and your body is also in the car Hold it by hand to the strap and balance it. By taking this form, it is possible to sit down in a narrow space in a minimum space, and as described above, it can greatly contribute to the improvement of health by preventing fatigue, back pain, etc., and the effective use of time.
