Description

[Detailed description of the invention] This invention relates to bedding for military use, mountaineering, etc., and is designed to prevent emergency situations when the bedding is closed by entering the bedding and pulling up the slider (slus) of the opening/closing fastener. To provide a device capable of urgently releasing a closed fastener and escaping from the bedding without having to open the bedding by pulling down a fastener slider when the user wants to escape from the bedding as quickly as possible in the event of an outbreak. The purpose is to

This will be explained in detail based on the drawings.

In Fig. 6, 4 is the bedding, 1, 1 is the left and right fastener chain of the bedding opening/closing fastener, which is long vertically disposed approximately in the center of the front of the bedding from the neck to the toes. Close it by pulling it up along the zipper chain to the neck, and open it by pulling it down.

The slider 2 has knobs on the outside and inside, respectively.

In the above-mentioned bedclothes, the present invention has a fastener part of a suitable length range at approximately the chest position of the bedclothes, so that when the slider 2 is pulled up to close the bedclothes, the slider 2 passes through that part. The left and right fastener chains 1, 1 of the part are made to form a non-closing part A without causing meshing.

1 to 3 are an enlarged plan view and a cross-sectional view of the non-closed portion.

Then, connect the left zipper chain side and the right zipper chain side to the inside of the bedding in the non-closing part A by straddling the non-closing part A and keep the non-closing part A open at all times. Fasteners 31, 32, and 33 are provided that are disengaged when a tensile force F, F' exceeding a set value is applied to the chest area of the bedding by greatly stretching it from side to side.

Further, as shown in FIG. 4, the upper ends of the left and right fastener chains 1, 1p are provided with a stopper 14 to prevent the slider 2 from being removed from the upper end of the fastener chain on one side, and an insertion fitting 16 that can be freely inserted into and removed from the slider 2 at the upper end of the other chain. Make it.

In Fig. 5, a stopper 15 is provided at the lower end of the left and right fastener chain 1.1 to prevent the slider from being pulled out, and a stopper 15 is provided at the lower end of the left and right fastener chain 1.1, and a stopper 15 is provided at the lower end of the other chain to prevent the slider from being removed. It is.

Each of the left and right fastener chains 1, 1 has a tape 11,
It consists of a string 12 at the edge of the tape, and clips 13 attached at predetermined intervals along the length of the string 12, and the tape 11 portion is attached by sewing, gluing, etc. along the opening edge of the bedding.

Figure 1 shows the fastener part of the appropriate length range at the chest area of the bedding, with the head 13' on one side of the fastener chain 1 left on the string 12 at the base, and the head removed in Figure 2. Opposing picks 13', 1 for fastener chains 1, 1
By deforming 3' into a shape without any meshing portions, the slider 2 can reciprocate through that portion without any trouble, but the grooves 13° 13', 13', and 13' in those portions are prevented from meshing. A non-closed part A was formed.

Therefore, slide slider 2 in the fastener closing direction (
When pulled up), the left and right fastener chains 1, 1 on the lower and upper sides of the non-closing part A in the middle of the fastener chain are engaged with each other, and the fasteners are closed, but the part A is Does not cause closure.

The illustrated example uses a hook-and-loop fastener (product name: Velcro fastener, magic fastener) as a stopper to keep the non-closing part A open at all times. Attach the hook-and-loop fastener piece 32 to the inner surface of the bedding 4, and attach the base of the second cloth 33 to the inner surface of the bedding 4 on the other side of the fastener chain.
6 pieces 3 that are paired with the above-mentioned hook and loop fastener piece 32 on the free end side
1 is attached.

To enter the bedding 4, pull down the slider 2 to open the bedding wide and then pull the slider 2 up to the neck to close the fastener chains 1, 1 over the entire length except for part A. Next, the fastener element piece 32 at the tip of the band 33 is fastened to the six pieces 31, and the band 33 is made to straddle the non-closing part A, thereby connecting the left fastener chain side and the right fastener chain side to form the non-closing part A. to prevent it from opening.

In the normal case, contrary to the above, the bedding is opened by releasing the stoppers 31 and 32 by hand and pulling down the slider 2 at the back of the neck.

If you have entered the bedding and closed the bedding and want to escape from the bedding as quickly as possible due to an emergency situation, press the chest area of the bedding with both elbows out to the sides and forcefully in the left and right direction. Make it stand out.

Then, due to the strong tensile forces F and F', the stopper 31.3
2 is forced to come off naturally.

At the same time as it comes off, a strong pulling-opening force in the left and right direction acts on the non-closing part A of the fastener, so that each of the closing fastener parts on the upper and lower sides of the non-closing part A sequentially naturally opens from the non-closing part A. It is easily released, and the bedding zipper naturally opens wide.

Then, by grasping the left and right opening edges of the bedding, which was wide open in the middle, and pulling it open even wider, the insertion fitting 16 at the upper end of one of the fastener chains was removed from the slider 2 at the neck ( 4), the bedding is completely opened.

In other words, the user does not have to manually search for the slider 2 at the neck and pull it down the entire length of the long zipper to the foot to widen the bedding, which is a relatively time-consuming operation.
As described above, the fastener in the closed state can be opened over its entire length in an emergency, thereby making it possible to escape from the bedding as quickly as possible in an emergency situation.

Since the non-closing part A is especially provided in the chest area of the bedding, when the person inside the bedding pulls both elbows strongly to the left and right, strong pulling forces F and F' in the left and right direction are effectively applied to the non-closing part A. It is possible to reliably release the stoppers 31, 32, and at the same time, it is possible to easily release the fastener in a way that it opens in the middle using the non-closing portion A as a starting point.

After the above-mentioned emergency opening of the fastener, in order to enable the slider 2 to open and close the fastener again, pull down the slider 2 at the upper end of one fastener chain 1 along the fastener chain until it hits the stopper 15 at the lower end, and then Slide the insertion fitting 17 at the lower end of the fastener chain onto the slider 2.
By inserting it in the same way as a conventional jumper fastener, the slider 2 can again be used to open and close the fastener.

The pressing force of the stoppers 31 to 33 that normally keep the non-closing part A open is, for example, the force of the child piece 31. The joint area of the O piece 32 can be adjusted to an appropriate value by appropriately designing the size as shown in FIGS. 1 and 2.

In addition to the hook-and-loop fasteners shown in the drawings, the fasteners 31 and 32 may be made of snaps or other fasteners that are released when a suitable tensile force F or F' is applied.

If the non-closing part A is formed by removing the heads of each of the lobes 13' in that part or deforming them into a shape that does not cause interlocking as shown in FIG. 1 or the example in FIG. 1, the flexibility of the fastener will be impaired. I won't let you.

[Brief Description of the Drawings] The drawings show an embodiment of the present invention, and FIG. 1 is a plan view of a non-closing fastener part, FIG. 2 is a plan view of another example, and FIG. 3 is a plan view of the non-closing fastener part. 4 is a plan view of the upper end of the fastener, 5 is a plan view of the lower end of the fastener, 6
The figure is a plan view of the bedding in the closed state. 1.1 is the left and right fastener chain of the slide fastener,
13 is a reel, 13' is a reel without interlocking action, 2 is a slider, and 31.32 is a stopper for opening and stopping the non-closing fastener part A in the middle of the fastener.
