Description

gloves

The present invention relates to a glove integrally formed of a film of rubber or resin as a whole.

As a glove for work in general household use to various industries, and as a medical glove, a substantially cylindrical sleeve and a glove main body which is continuous with one end of the sleeve and protects from the wrist to the fingertip are natural rubber, acrylonitrile-butadiene A glove which is integrally formed of a synthetic rubber such as rubber (NBR) or a resin such as a vinyl chloride resin or a urethane resin and which has the other end of the sleeve open as a cuff is widely used.

The gloves have various thicknesses, but in recent years, in order to improve the fit to the hand and the workability in the state of wearing the gloves, in particular, the gloves are formed only by the thin film of rubber or resin. The demand for soft, flexible gloves tends to increase.
However, the more flexible and the thinner the film, the lower the rigidity tends to be. Therefore, for example, when the thin glove is worn and actually used, the sleeve that should cover the area from the wrist to the forearm may fall toward the glove body, or the entire glove may be easily detached or detached from the hand. For example, when used for water work, there is a problem that bouncing water comes in and there is no point in wearing gloves.

In order to solve the above-mentioned problems, for example, in

Patent Documents

1 and 2 and the like, a prevention tool for clipping a cuff of a glove to prevent slipping is proposed, but such a prevention tool is used prior to use of the glove. Wearing or removing after use is troublesome.
Patent Document 3 describes a glove provided with a strap at the cuff of the glove, but it is also troublesome to tighten the strap prior to use of the glove or loosen it after use.

Patent Document 4 describes a tubular elbow used in combination with a short glove and provided with a plurality of pleats reaching from the one end side to the other end side. The elbow protector is unlikely to slip off the elbow due to the circumferential stretchability by providing the pleats, but such an elbow protector, together with the glove, has no gap between the two. Wearing or removing with gloves is still cumbersome. In addition, during use, the elbow protector may be displaced due to, for example, expansion and contraction of the elbow, causing a gap between the glove and the glove, and water may infiltrate from there, which is not perfect.

JP 2007-119982 A JP 2008-2044 A Japanese Patent Application Laid-Open No. 11-286809 Japanese Utility Model Application Publication No. 4-97805 Japanese Utility Model Publication No. 49-82913 Japanese Utility Model Application Publication No. 3-24114

The object of the present invention is to allow the sleeves to slip towards the body of the glove, or the entire glove to come off or come out of the hand, without putting on and taking off the guard or attaching it with the elbow protection. It is to provide a glove that can reliably prevent the ingress of water and the like as a result.

In order to solve the above problems, the inventor forms a pleat over the entire circumference of the sleeve part of the glove to impart good stretchability to the sleeve part, and the sleeve part is shifted toward the glove body We considered to prevent falling and the whole glove from coming off the hand or coming off. However, in the case where pleats with a constant depth, such as the pleats of the elbow protection described in Patent Document 4 described above, are provided in the sleeves,
・ The tightness against the narrowest wrist, especially in the forearm, becomes worse, and the workability in the state of wearing the glove decreases.
・ It was found that the sleeve was folded back and down in the middle of the work, and the water splashed during water work could not surely be prevented from invading from the cuff.

In order to prevent folding and sagging, the rubber or resin film should be thickened to increase the rigidity, but in that case the amount of rubber or resin forming the glove will increase and the glove will become heavier or the cost will There is a problem of getting expensive.
Therefore, as a result of further examination of the depth of the pleats, it was found that the depth of the pleats formed over the entire circumference of the sleeve may be gradually deepened from one end connected to the glove body toward the cuff. It came to complete.

That is, according to the present invention, the substantially cylindrical sleeve portion and the glove main body connected to one end of the sleeve portion are integrally formed of a film of rubber or resin, and the other end of the sleeve portion is opened as a cuff. The sleeve portion is provided with a plurality of pleats that reach the cuff from one end connected to the glove body over the entire circumference, and each pleat has a gradually increasing depth from the one end to the cuff It is characterized by the fact that

According to the present invention, as described above, while providing pleats that reach the cuff from one end connected to the glove body over the entire circumference of the sleeve, the depth of each pleat is made shallow in the vicinity of the one end. (1):
Expansion ratio E = R ₂ / R ₁ (1)
[Wherein, R ₁ represents the circumferential length in a free state where no stress is applied to each part forming the glove, and R ₂ represents the circumferential length when stretching is performed until pleats disappear in the same place. The expansion and contraction ratio E determined by

Therefore, among the sleeves, the vicinity of the one end corresponding to the narrowest wrist among the forearm can be firmly fitted to the wrist, and the workability in the state of wearing the glove can be improved.
Moreover, since the appropriate stretchability can be provided near the one end by the pleat provided on the entire circumference, there is no possibility that the ease of wearing of the glove is impeded.

In addition, since the depth of each pleat is gradually increased from the one end toward the cuff, the thickness of the rubber or resin film forming the sleeve is not increased. It is also possible to provide appropriate rigidity to prevent the occurrence of folding or drooping. In addition, it is not necessary to increase the thickness of the sleeves, and the amount of rubber and resin forming the glove can be increased to prevent the glove from becoming heavy and costly.

There is no particular limitation on the extent to which the depth of the pleats differs between one end of the sleeve and the cuff, but it is expressed by the expansion ratio E determined by the equation (1). It is preferable to set a range of 1 / 0.9 or more and 1 / 0.6 or less in the cuff and to gradually increase the stretch ratio E from the one end to the cuff.
The stretch ratio E is 1 at one end of the sleeve and no pleat is formed at the one end, and the sleeve is in the vicinity of the wrist on the one end side by gradually deepening the pleat from there toward the cuff The effect of making it fit well can be further improved.

In addition, by setting the expansion ratio E to 1 / 0.9 or more in the cuff, it is possible to further improve the effect of imparting appropriate rigidity to the sleeve to prevent folding and drooping. In addition, it is preferable that the stretch ratio E of the cuff is 1 / 0.6 or less because, for example, at the time of manufacture of a glove by a general immersion method, uneven thickness and cracks occur due to the pleat being too deep in the cuff. To prevent In the case where such uneven thickness or cracking occurs, on the contrary, folding or drooping tends to occur.

The length of the sleeve from the one end to the cuff is preferably 10 cm or more. Shorter sleeves are less prone to folding and drooping, but if they are shorter than the above-mentioned range, there is a possibility that the splashed water can not be reliably prevented from entering during water work.
The thickness of the rubber or resin forming the glove is considered to prevent the glove from becoming heavy or expensive due to an increase in the amount of rubber or resin forming the glove as described above. Then, it is preferable that it is 2.0 mm or less. However, if the thickness of the membrane is too small, even if pleated, it may not be possible to prevent the occurrence of folding or sagging by giving an appropriate rigidity to the sleeve. Therefore, the thickness of the membrane is preferably 0.1 mm or more.

According to the present invention, the sleeves fall off toward the glove body, or the entire glove slips out of the hand, without putting on and taking off the guard or attaching it with the elbow protection. As a result, it is possible to provide a glove in which water and the like are less likely to intrude.

It is a front view showing an example of an embodiment of a glove of the present invention. It is a figure explaining the outline of the pleat of the glove of the example of FIG.

FIG. 1 is a front view showing an example of the embodiment of the glove of the present invention. FIG. 2 is a view for explaining an outline of pleats of the glove of the example of FIG.
With reference to both figures, in the glove 1 of this example, a substantially cylindrical sleeve 2 and a glove body 3 connected to one end of the sleeve 2 are integrally formed of a rubber or resin film, and the sleeve The other end of the part 2 is opened as a cuff 4.

The glove body 3 has a palm 5 connected to the sleeve 2 and a plurality of fingers 6 connected to the palm 5 corresponding to the shape of a hand as in the prior art.
The sleeve portion 2 is formed of a first sleeve portion 8 on one end 7 side connected to the glove body 3 side, and a second sleeve portion 9 constituting the cuff 4. Both sleeves 8 and 9 are integrally connected at the boundary 10.
The first sleeve portion 8 is formed in a substantially truncated cone shape whose circumferential length gradually increases from the one end 7 side toward the boundary portion 10. The second sleeve 9 is formed in a substantially truncated cone shape whose circumferential length gradually increases from the boundary 10 to the cuff 4. The circumferential lengths of the two sleeves 8 and 9 at the boundary 10 are the same, whereby the two sleeves 8 and 9 are integrally connected over the entire circumference.

The slope of the generatrices forming the conical surface of the second sleeve 9 is greater than the slope of the generatrices constituting the conical surface of the first sleeve 8 so that the second sleeve 9 opens largely at the cuff 4 It is done.
Plural pleats 11 that reach the cuff 4 from one end 7 connected to the palm part 5 of the glove body 3 are provided on the sleeve part 2 consisting of both sleeve parts 8 and 9 over the entire circumference.

Each pleat 11 is formed in a substantially sine curve shape in cross section as shown in FIG. Each pleat 11 has a depth D shown in FIG. 2 gradually deepened from one end 7 to the cuff 4.
There is no particular limitation on how much the depths of the pleats 11 are different between one end 7 of the sleeve 2 and the cuff 4, but in the free state where no stress is applied to the parts forming the glove 1. From the circumferential length R ₁ and the circumferential length R ₂ when the pleats are extended, Formula (1):
Expansion ratio E = R ₂ / R ₁ (1)
When it is expressed by an expansion ratio E which is obtained by the equation (1), it is preferable to set it in the range of 1 / 0.9 or more and 1 / 0.6 or less in 1 at the one end 7 and in the cuff 4.

By setting the expansion ratio E to 1 at one end 7 and forming no pleats at the one end 7, gradually deepening the pleat from there toward the cuff 4, the first sleeve 8 at the one end 7 side It can be fitted firmly around the wrist.
Moreover, since the appropriate stretchability can be provided near the one end 7 by the pleats 11 provided on the entire circumference, there is no possibility that the ease of wearing the glove 1 is impeded.

In addition, by setting the expansion ratio E to 1 / 0.9 or more in the sleeve 4, the sleeve 2, that is, the first and second sleeves 8, 9 is given appropriate rigidity to prevent folding and sagging. can do. The stretch ratio E of the cuff 4 is preferably 1 / 0.6 or less because, for example, when the glove 1 is manufactured by a general immersion method, the uneven thickness associated with the pleat 11 being too deep in the cuff 4 or It is for preventing that a crack arises. In the case where such uneven thickness or cracking occurs, on the contrary, folding or drooping tends to occur.

The specific depth D of the pleats 11 can be arbitrarily set to satisfy the expansion ratio E according to the size of the glove 1 etc., but the cuff 4 is preferably 3 mm or more, particularly 4 mm or more, It is preferably 7 mm or less, particularly 6 mm or less.
By setting the depth D of the pleats 11 in the cuff 4 within the above range, the cuff 4 is given appropriate rigidity while preventing occurrence of uneven thickness or cracking during manufacturing of the glove 1, and folding or sagging is caused. It can be prevented.

The length L of the sleeve 2 from the one end 7 to the cuff 4 is preferably 10 cm or more, and more preferably 20 cm or more. As the sleeve 2 is shorter, it is less likely to cause folding or drooping, but if it is shorter than the above range, there is a possibility that the splashed water can not be reliably prevented from entering during water work.
The length L is preferably 40 cm or less, particularly 30 cm or less, in consideration of covering up to the vicinity of the elbow, for example.

The thickness of the rubber or resin forming the glove 1 is to prevent the glove from becoming heavy or costly because the amount of rubber or resin forming the glove 1 is increased as described above. It is preferable that it is 2.0 mm or less, especially 1.5 mm or less in consideration of. However, if the thickness of the membrane is too small, even if the pleats 11 are attached, there is a possibility that the sleeve 2 can not be provided with an appropriate rigidity to prevent the occurrence of folding or drooping. Therefore, the thickness of the film is preferably 0.1 mm or more, particularly 0.2 mm or more.

The entire glove 1 does not have to be within the above thickness range, and for example, the cuff 4 is made thicker than the other portions to give appropriate rigidity so as to further prevent folding or drooping, or the tip of the finger 6 May be thicker than other parts to protect the fingertip.
The glove 1 can be configured in the same manner as the conventional one except that the sleeve 2 has the pleats 11.
For example, the glove 1 is formed by depositing a rubber latex in the shape of the glove 1 shown in FIG. 1 by dipping as in the prior art and vulcanizing the rubber or forming an emulsion of resin into the shape of the glove 1 by dipping. It can be manufactured by drying and solidifying the resin while filming.
