Description

When sitting in a seat for a long time, such as a movie, a theater or an event, carry your carry-on baggage etc. to the end of the portable lifting device attached to the upper back of the front row seat and secure your carry-on baggage above the knee The present invention relates to a portable hanging device for reducing the troublesomeness and pain caused by things.

When women go out, they often go out with a variety of hand luggage, such as handbags containing cosmetics and valuables, paper bags containing shopping items, cloth bags and paper bags containing light clothing for fashion, and the like.
In particular, in the case of movies, theater plays, entertainments, etc. that will sit on the seat for a long time, these baggage are placed on the knees and held and held. Holding a baggage that is bulky and relatively heavy as a whole on the knee for a long period of time hinders viewing and is painful.

Of course, if you are in a movie theater, theater, or event hall with baggage deposits, you will not need to consider these difficulties. Often sits secure. In such a case, there is a need for a portable lifting device for releasing the troublesomeness and pain of securing the baggage above the knee.

  With respect to such a portable hanging device having a purpose, techniques such as those disclosed in registered utility model No. 3133339 and Japanese Patent Laid-Open No. 9-191975 are disclosed.

Registered Utility Model No. 3133339 Patent Publication No. Hei 9-191975

  As a result of investigating public patents and public utility models as a technology related to the hanging tool, for example, a thin string with a hook for hanging baggage on a built-in spiral spring such as registered utility model No. 3133339 is bound and removed. Although there is a portable hanging device that adjusts the length, it is a box type that can accommodate the entire device, and it cannot be used without a hanging source that suspends the box.

In addition, the portable hanging tool used on the seat or the shoulder of the chair as disclosed in Japanese Patent Laid-Open No. Hei 9-191975 is made of a metal rod, and it is quite large and not easy to carry. From the viewpoint of small size, light weight, and ease of use required for the device, it was difficult to apply to seats in movie theaters and theaters. Various other hanging devices have been devised, but they are often unsuitable for easy application to seats in movie theaters and theaters.

In order to hang baggage using the horseshoe-shaped part on the backrest of the seat of a theater or the like, a metal plate, a metal pipe, or a metal rod that matches the horseshoe shape as shown in FIG. Luggage can be suspended by joining a metal plate or metal bar bent in a U-shape.
However, since the horseshoe shape at the upper part of the seat back is not necessarily the same shape, portable suspension devices made of metal plates, metal pipes, and metal rods will be dedicated to the corresponding seat and will be transferred to other seats. There will be no versatility.

Or, there is a shape like Japanese Patent Publication No. Hei 9-191975 as a portable hanging device having versatility, but the size is large and a woman cannot carry it in a handbag.
Therefore, the portable hanging device is required to be small, light and versatile.

In addition, there is a deformable metal pipe called a flexible tube on the market, and a form of a portable hanging device that can be used in accordance with the horseshoe shape of the seat backrest of various shapes is conceivable. However, there is a possibility that it may become incompatible with the sense of women in the following points.

It is essential for women to be fashionable, lightweight, and small portable items when they go out. It is unthinkable for a woman to go out with a metal bulky portable lifting device as described above. In addition, when it is put into practical use as a portable hanging device, it is necessary to consider the embarrassment of being seen with strange eyes from the surrounding audience in the theater.

Therefore, the portable hanging device is stylish enough to be put in a small handbag, lightweight, small size is essential, and it will not stand out even if it is attached to the horseshoe-shaped part above the seat back of a movie theater, theater, etc. It must be in shape.

The first idea to solve the above problem is
It is a portable suspension device consisting of a spiral spring and a rotating coat hook that is swirled under no load condition. This is a portable lifting device that can be used to hang baggage and the like on a rotating coat hook, and is fixed as a force that holds the upper shoulder of the seat back.

    Further, the second device is the first device, wherein the spiral spring has a length of 300 to 350 mm, a width of 25 to 35 mm, a thickness of 0.05 to 0.1 mm, and a weight of 20 to 25 g. Is a portable hanging tool having a width of 4 to 8 mm smaller than the width of the spiral spring and a weight of 20 to 30 g.

  It was recognized that the weight of the baggage that can be hung on the portable lifting device can be obtained up to 2.0KG by using the spiral spring. The load that can be hung by this portable lifting device takes into consideration the weight of handbags that women have when going out of the movies, theater, entertainment, etc., essential items such as cosmetics and valuables, and the weight of portable umbrellas or parasols depending on the weather. As a result, it was found that the total weight was about 0.5 to 1.5 kg. Therefore, in consideration of these carry-on items, shopping items, etc., the weight by which the portable hanger is hung is a portable hanger that retains the ability to hang a weight of about 1.0 to 2.0 kg. Is necessary and can be achieved by using a spiral spring.

When attaching this portable lifting device to the outer periphery of the horseshoe shape (shoulder part) on the backrest of the front seat, the swirl is extended horizontally and attached so as to follow the outer periphery of the horseshoe shape (shoulder part) of the upper part of the seat backrest. To do.
The thickness of this portable lifting device is as thin as 1.5 to 2.0 mm even if the case thickness of the storage band bag for safety measures is added, compared to the portable hanging device that is made of the above-mentioned metal material etc. In addition, it is flat and does not stand out, and there is little worry that the surrounding audience can see with strange eyes.

In addition, the total weight of the portable lifting device is 40-60g even if the weight of the storage band bag for safety measures and the rotating coat hook is combined, and it is extremely small and lightweight. No burden on the bulky enemies.
In addition, it is possible to create a stylish feeling by printing flowers, small animals, illustrations, etc. on the surface side of the belt-like bag that houses the spiral spring, and it can be seen with strange eyes from the surrounding audience when it is implemented Can be avoided.

When the portable suspension is mounted on the outer periphery of the horseshoe shape (shoulder portion) at the top of the back of the seat, it exerts the force of holding the horseshoe shape portion (shoulder portion) and withstands the force in the falling direction generated by hanging baggage A spiral spring is used as a structural material for a portable lifting device capable of (holding a baggage).

  The spiral spring used in the present invention is in a spiral state in a no-load state as indicated by 6 in FIG. The spiral spring used in the present invention has a width of 28 to 40 mm, a length of 250 to 350 mm, and a thickness of 0.05 to 0.00 as shown in FIGS. A 1 mm spiral spring is suitable.

The spiral spring used in the present invention is curled up like 6 in FIG. 3 when not in use (no load state), and the size of the spiral state is small with a diameter of 35 to 45 mm and a width of 25 to 40 mm. Because it is cylindrical, it can be gripped by the palm of your hand and fits enough in a small handbag that a woman has.

The portable lifting device made of spiral springs is small and rounded, but when used, hold one end of the spiral spring (rotating coat hook) and stretch it straight so that you can hold your back seated shoulder Hang.
The force that the spiral spring tries to return to the original full state can be used as a force to hug the front seat backrest shoulder, and by adding safety and anti-slip measures to the front seat backrest shoulder Maintained without misalignment.

A commercially available rotating coat hook shown in FIG. 3 is used as a tool for hanging baggage as a portable hanging tool.
In order to attach the rotary coat hook to the spiral spring, as shown at 12 in FIG. 5, a hole is previously formed at the position 8 in FIG. 4 of the spiral spring so as to match the position of the attachment hole of the rotary coat hook. Secure with bolts, nuts or special caulking tools.

There are articles with fixed buttocks on the coat hooks used in the living room, but it can be bulky in small handbags held by women. Goods are desirable.

If the spiral spring is used bare, the thickness is as thin as 0.05 to 0.1 mm, so that there is a risk of damaging a finger cut or other small items in the handbag. Also, since the surface of the spiral spring is extremely smooth, when it is used naked, the force to return to the original full state cannot slide back on the front seat shoulder and reach the purpose of the portable lifting device. There is a possibility.

Therefore, it has become possible to firmly achieve the purpose of the portable lifting device by adding the following measures for preventing cuts and fixing to the front seat back shoulder.
(1) Safety measures such as cut prevention The spiral spring with a width of 25 to 40 mm, a length of 250 to 350 mm, and a thickness of 0.05 to 0.1 mm used in the present invention is inserted into a specially manufactured belt-like bag. use. The material of the belt-like bag can be a sheet made of a synthetic resin such as a fabric (woven fabric), a vinyl resin, a polyurethane resin, or a polyester resin. The weight of the belt for safety measures is 5 to 10 g for a fabric (woven fabric) and 20 to 25 g for a molded product of a synthetic resin sheet.
The total weight of these three types of portable suspension material is 50 g to 60 g, but it does not feel a burden as belongings for women.

Two pieces of these fabrics (woven fabrics) or synthetic resin sheets are overlapped and cut 8 mm longer than the width and length of the constant load spring. By sewing two pieces of fabric (woven fabric) or one side of the short side of the synthetic resin sheet after cutting and one side of the short side in the case of fabric (woven fabric), and by heat-sealing in the case of synthetic resin sheet Use a belt-like bag.
Thereafter, a constant load spring is inserted into the belt-like bag, and one side of the opened belt bag is sewn or heat-sealed to confine the constant load spring belt, thereby preventing the occurrence of cuts.
Of course, a hole for attaching the rotary coat hook is opened at a predetermined position at the end of the belt-like bag on the rotary coat hook attachment side.

(2) Anti-slip measures when attaching mobile suspensions In the case of fabric (woven fabric) bags inserted with spiral springs, friction with the fabric (woven fabric) covering the seat surface of movie theaters and theaters is obtained, and synthetic resin is obtained. It is thought that it is harder to slip than a belt-like bag of sheet material.
However, since it cannot be said that it does not slip completely, as a countermeasure against slipping, the hook type side of the hook-and-loop fastener is sewn or attached to the side facing the seat on the side without the rotation coat hook.

As shown in FIG. 6 at 14, the hook-and-loop fastener type is suitably one having a length of 1/3 to 1/2 of the portable suspension from the opposite end to which the rotary coat hook is attached.
Also in the case of a synthetic resin sheet, it is desirable to attach a hook-and-loop fastener / hook type with an adhesive on the side facing the seat as described above.

  The present invention provides new portable products to the market and is effective for industrial promotion.
