Description

OBJECTS OF THE INVENTION (TECHNICAL FIELD) The present invention relates to flexible synthetic resin or natural or synthetic rubber gloves. More specifically, the invention relates to flexible synthetic resin, natural or synthetic rubber gloves that have a good fit, allow delicate work to be performed efficiently, and do not cause hand fatigue even when worn for long periods of time.

(Prior Art) Conventionally, gloves used for medical purposes, IC circuit manufacturing, household use, etc. are designed to prevent the Ube from getting wet from contact liquids, and to prevent bacteria, microorganisms, dust, etc. from being transferred from the Ube to the object being touched. Alternatively, the purpose is to prevent movement from the object to be contacted to the Ube, and various flexible synthetic resins and natural and synthetic rubbers are generally used as the material.

Now, with such gloves, in order to improve the workability of the wearer, especially when performing detailed work, it is necessary to wear one part of the glove, especially the fingertip part, in close contact with the wearer. It is desirable to have a configuration that allows However, if the gloves are in close contact with the hands, the movements of the palms, especially the fingertips, will not be slowed down by the gloves.
This is because the information is accurately transmitted to the object to be contacted.

However, conventional gloves with good adhesion are
When working while wearing the device for a long period of time, faculty members felt extremely tired. This means that if the glove has good adhesion, when you bend each joint of your hand to move the flat part, especially the fingertips, the part of the glove that touches each joint on the back of the hand will locally stretch further. Therefore, a force is absolutely required to elastically deform the glove. The power for this is
This is not a big problem when the work is done for a short time, but when the work is done for a long time, the burden placed on the faculty becomes quite large. In addition, when the parts of the back of the hand that come into contact with the joints are further stretched locally, the flat part feels quite tense, causing discomfort to the wearer and increasing fatigue. Put it away.

Therefore, flexible synthetic resin or natural or synthetic rubber gloves, which are conventionally used in cases where gloves are expected to be worn for a relatively long time, do not cause discomfort or fatigue in order to maintain workability. Did it have strong adhesion even if you gave it?
Although its workability is poor, it is constructed so that it can be worn relatively loosely.

(Problems to be Solved by the Invention) The present invention attempts to solve the problems of the conventional products as described above.

It is, therefore, an object of the present invention to provide a new flexible synthetic resin or natural or synthetic rubber glove.

The present invention also provides a good adhesion feeling and allows for efficient work.
It is an object of the present invention to provide gloves made of flexible synthetic resin or natural or synthetic rubber that do not give a feeling of fatigue to the hands even when worn for a long time.

Structure of the Invention (Means for Solving Problems) In order to achieve the above-mentioned objectives, the present invention has been made as a result of repeated studies on various improvements in the structure of gloves made of flexible synthetic resin or natural or synthetic rubber. When wearing the r! The present invention was achieved by discovering that by offsetting the local stretch of the iJ joint when the joint is bent by the slack, the burden placed on the hand when bending the joint can be reduced.

That is, the present invention is a glove made of flexible synthetic resin or natural or synthetic rubber, characterized in that it has slack in at least a portion of the region that contacts the joint of the back of the hand when worn.

(Example) Hereinafter, the present invention will be explained in detail based on examples.

FIG. 1 is a drawing showing a glove 1 of the present invention viewed from the inside of the hand. Therefore, the parts 2 to 15 of the glove 1 that come into contact with the l$HD part on the back of the hand have slack. Note that although this example shows slack in the parts that contact all the metacarpophalangeal joints and interphalangeal joints on the back of the hand, it is not necessary to have slack in all of these parts. It may have some slack. Among the parts 2 to 15 that contact the metacarpophalangeal joints and the interfinger rf411i5 parts, the greatest effect can be expected by having slack in the parts that contact the metacarpophalangeal joints of the 1st to 5m fingers. These are parts 2 to 6, and the next parts are part 7, which contacts the interphalangeal joint of the first finger, and part 8, which contacts the interphalangeal joint between the base and middle S* base of the second to fifth fingers. ~11, and f12
The order is from fingers to parts 12 to 15 that contact the interphalangeal joint between the 541st middle phalanx and the distal phalanx base.

In this way, the slack formed at the part that comes into contact with the joint part of the back of the hand when worn is that when the joint is stretched, the part in question is stretched more than the part near the part of the hand. The shape is not particularly limited, as long as the joint has enough space to allow the joint to come into contact with each other more easily when the joint is bent. It may be several vertical wrinkles, one to several horizontal wrinkles perpendicular to the direction of the fingers, or a network of wrinkles, but it is preferable to use the wrinkles on the fingers because of the ease of molding. Vertical wrinkles roughly along the direction are desirable.

Further, these sag may be wrinkles in the shape of mountains in the thickness direction as shown in FIGS. 2A to 2B, or wrinkles in the shape of peaks and valleys in the thickness direction as shown in FIG. 2C. However, it is desirable that the wall thickness of such a slack portion be substantially the same as at least the wall thickness of a portion in the vicinity thereof. In other words, if the thickness of the slack part is thicker than that of the surrounding parts, there is a risk that when the joint is bent, the parts in the vicinity of the slack part will be stretched; This is because the strength of that part decreases.

Furthermore, the glove of the present invention has good adhesion to the fingertips as a whole when worn.

The materials constituting the gloves of the present invention include flexible synthetic resins such as soft polyvinyl chloride, low-density polyethylene, polypropylene, polyester, and polystyrene, natural rubber, styrene rubber (S13R), and butadiene rubber (BR).
Any known material such as nitrile rubber (NBR), synthetic rubber such as urethane rubber, etc. can be used.

The glove of the present invention can be easily molded using the above-mentioned materials, for example, as follows. That is, gloves made of flexible synthetic resin or natural or synthetic rubber are usually made by dipping a knife into a solution or paste of flexible synthetic resin, or rubber paste or latex of natural or synthetic rubber, and then carrying out a predetermined process. Since it is manufactured through a long process, if the part corresponding to the joint of the hand of the knife shape used for this dipping work is provided with an unevenness in the desired shape to create 1q of slack, then the knife shape can be used for dipping. A desired glove can be obtained by dipping in the same manner as in the manufacturing method of conventional products.

In this case, as mentioned above, if the slack is a vertical wrinkle substantially along the direction of the fingers of the hand, a good product can be obtained without the risk of uneven thickness of the slack part due to dripping.

Effects of the Invention As described above, the glove of the present invention is characterized in that the glove made of flexible synthetic resin or natural or synthetic rubber has slack in at least a portion of the part that comes into contact with the joint part of the back of the hand when worn. Because the gloves are meant to protect your hands,
In particular, even if it fits well on the fingertips, it is very easy to bend and straighten the vjw of the hand, and there is no feeling of extreme tension when bending the joints, so you can wear it for a long time and work. These gloves have excellent workability and do not make you feel tired when performing magic tricks, and they can be easily manufactured by simply shaping the desired shape onto a knife, no different from the manufacturing method of conventional products. It is.
