Abstract

This glove includes a main glove section provided with a plurality of finger parts, the glove being formed integrally from a rubber or resin film, wherein in at least one finger part of the plurality of finger parts, the circumferential length at a position one-sixth of the finger length from the tip is 55%−80% of the circumferential length at a position 2/3 of the finger length from the tip.

Description

gloves

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

Background Art In general homes, factories, medical facilities, sports, etc., gloves integrally formed of a film of rubber or resin are widely used to protect the skin from hand and injury.
Conventional gloves of this type are generally made larger than the size of the real person's hand so that many people can use it.

However, since the finger part of the glove that accommodates the finger is longer or thicker than the finger of an actual person's hand, the finger plays in the finger part when wearing the glove. Or it is easy for the whole glove to slip out of the hand. As a result, there is a problem that the fit to the hand of the glove and the grip when holding an object through the glove become low, making it difficult to work with the glove.

Patent Document 1 discloses a glove provided with a large number of projections on the ventral side of a plurality of finger portions for use in hair washing. Further, in claim 2 of Patent Document 1, it is described that the tip end portion of the finger portion is made thinner.

JP 2005-200820 A

However, as can be seen from FIGS. 1 to 7 of Patent Document 1, “to make the tip end thinner” means to form the tip portion into a tapered shape in accordance with the shape of the fingertip of a human hand. .
Therefore, although there is no problem in pressing the fingertip against the scalp to wash the hair, in the case of work other than shampooing, the force is applied to the fingertip from various directions. The fit to the hand of the glove and the grip when grasping an object through the glove can not be improved.

The object of the present invention is to be able to fix the fingers firmly to the user's fingertips, to improve the fit to the hand of the glove and the grip when grasping an object through the glove, and work in a gloved state Provide gloves that can be easily

The present invention is a glove including a glove body provided with a plurality of finger portions, and integrally formed of a rubber or resin film, wherein at least one finger portion of the plurality of finger portions has a tip-to-finger length. The circumferential length of the 1/6 position is 55% or more and 80% or less of the circumferential length of the 2/3 position of the finger length from the tip.
According to the present invention, as described above, the circumferential length of the 1/6 position of the finger length from the tip of the at least one finger portion of the glove is smaller than the circumferential length of the 2/3 position of the finger length from the tip. As a result, the region near the 1/6 position can be firmly fitted and fixed to the end segment that is the fingertip side of the so-called first joint (distal interphalangeal joint) of the finger. In addition, by increasing the circumferential length of the 2/3 position to allow a space between it and the finger, it is possible to secure the freedom of bending and extending of the finger joint.

Therefore, it is possible to improve the fit to the hand of the glove and the grip when grasping an object through the glove, and it is easy to work with the glove.
The circumferential length of the 1/6 position is limited to the above range for the following reason.
That is, if the circumferential length at the 1/6 position is less than 55% of the circumferential length at the 2/3 position, a pressure sensation is produced at the end segment of the finger, and the sense of the fingertip which is the belly of the end segment is impeded. On the other hand, if it exceeds 80%, the circumferential length at the 1/6 position is reduced as described above, and the effect of firmly fitting and fixing the region near the position to the end of the finger can not be obtained. Therefore, in either case, the workability is rather reduced.

In addition, when the circumferential length at the 1/6 position is less than 55%, there is also a problem that it becomes difficult to attach and remove the gloves.
In the glove, it is preferable that the 1/6 position and the 2/3 position be connected via a step portion. As a result, compared with the case where the circumferential length between the two positions is gradually increased, it is possible to make the joint portion of the finger more loose. As a result, the flexibility of bending and extending of the finger joints can be further enhanced, and the workability can be further improved.

In the glove, the circumferential length at 1/6 position of the finger length from the tip of the finger portion corresponding to the third finger is 55% or more of the circumferential length at 2/3 position of the finger length from the tip, 80% It is preferable that it is the following.
Since the third finger is located at the center of the hand, the circumferential length of the 1/6 position of the finger length from the tip of the finger corresponding to the third finger is the circumferential length of the 2/3 position of the finger length from the tip If it is 55% or more and 80% or less, the fit to the hand of the glove and the grip when holding an object through the glove can be improved in a well-balanced manner throughout the glove.

According to the present invention, the fingers can be firmly fixed to the user's fingertips, so that the fit to the hand of the glove and the grip when grasping an object through the glove can be improved, and work in a gloved state Can provide easy to wear gloves.

It is a perspective view showing the glove body which is the principal part of the glove concerning one embodiment of the present invention. It is an enlarged side view of the finger part corresponding to the 3rd finger (middle finger) of the glove body of FIG.

FIG. 1 is a perspective view showing a glove body which is a main part of a glove according to an embodiment of the present invention. FIG. 2 is an enlarged side view of a finger unit corresponding to the third finger (middle finger) of the glove body of FIG.
Referring to both figures, the glove 1 of this example is integrally formed of a rubber or resin film 3 as a whole including the glove body 2. Although not shown, the glove body 2 is formed with a sleeve having an arbitrary length. One end of the sleeve portion is opened as a cuff for a user to put his hand.

The glove body 2 includes a palm 5 connected to the sleeve via the wrist 4 and a plurality of fingers 6 connected to the palm 5 corresponding to the shape of the hand.
Each finger portion 6 is formed in a tubular shape as a whole by the rubber or resin film 3 and the fingertip 7 side is closed. On the other hand, the proximal end 8 side where the finger portions 6 are connected to the palm portion 5 is an opening for the user to insert a finger.

Further, in the case of the illustrated example, each finger portion 6 is a line segment L obtained by dividing the finger length into six equal parts from the tip P on the side of the fingertip 7 at one-third position of the finger length, that is, as shown in FIG. The region up to the position of 2 is formed in a tubular shape having a diameter smaller than that of the region on the proximal end 8 side and substantially the same diameter.
Thereby, as described above, it is possible to firmly fit and fix the small diameter region at the distal end portion which is the fingertip side of the so-called first joint (distal interphalangeal joint) of the finger.

In addition, the peripheral length of the area on the proximal end 8 side of the small-diameter area is increased to provide a space between the small area and the finger, so that the flexibility of the finger joint can be secured.
Therefore, it is possible to improve the fit to the hand of the glove and the grip when grasping an object through the glove, and it is easy to work with the glove.
Further, between the two regions (between the region from the tip P to the position of two line segments L and the region on the base 8 side with respect to this region), from the fingertip 7 side to the base 8 side It is formed in the shape connected by the taper-shaped level | step-difference part 9 to which diameter becomes large gradually by taking it. As a result, compared with the case where the circumferential length between the two regions is gradually increased, it is possible to make the joint portion of the finger more leeway. As a result, the flexibility of bending and extending of the finger joints can be further enhanced, and the workability can be further improved.

In the case of the illustrated example, the step portion 9 is formed so as to expand mainly to the back side (upper side in FIG. 2) of the finger from the fingertip 7 side to the base end 8 side, and the belly side of the finger. (The lower side in FIG. 2) is formed to be substantially flush. This can further improve the grip when holding an object through gloves.
Moreover, although the finger tips 7 of all the finger parts 6 are formed in the said shape in the figure, in this invention, only one finger tip 7 of the five finger parts 6 is formed in the said shape, and the other fingers The fingertip 7 of the portion 6 may be formed to have substantially the same diameter as that of the proximal end 8 as in the prior art. Alternatively, the fingertips 7 of the two, three or four fingers 6 may be formed in the above-mentioned shape, and the remaining fingers 6 may be formed in a conventional manner.

The fingertips 7 of at least one finger portion 6 may be formed in the shape shown in the figure.
Although at least which finger portion 6 of the finger portion 6 is to be formed into the shape shown in the figure can be arbitrarily selected, it is particularly preferable to form the finger portion 6 corresponding to the third finger (middle finger) of the hand into the shape shown. Since the third finger is located at the center of the hand, if the finger portion 6 corresponding to the third finger is shaped as shown in the figure, the fit to the hand of the glove 1 or when grasping an object via the glove 1 Grip performance can be improved in a well-balanced manner throughout the glove 1.

In the present invention, at least one finger portion 6 forming the fingertip 7 in the shape of the figure, particularly preferably the finger portion 6 corresponding to the third finger, 1/6 position of the finger length from the tip P of the finger tip 7, That is, as shown in FIG. 2, the circumferential length C ₁ of _one position of the line segment L obtained by equally dividing the finger length from the tip P into two, 2/3 position of the finger length from the tip P, ie from the tip P the line L of the four minute position in the circumferential length _C 55% ₂ or more, set at 80% or less.

The reason is as described above. That circumference C ₁ of the 1/6 position is less than 2/3 55% circumference C ₂ position, on causing tightness in the end joint portion of the finger, sensation of the fingertip which is the belly of the distal segment portion is obstructed Be On the other hand, when it exceeds 80%, the previously described, 1/6 effects a region near the position to reduce the circumferential length C ₁ fixed by firmly fit the end joint portion of the finger position is obtained Absent. Therefore, in either case, the workability is rather reduced.

In addition less than the circumferential length C ₁ is the 55% 1/6 position, there is a problem that detachment of the glove 1 is hard to.
Other dimensions, shapes and the like of the finger portion 6 are not particularly limited. For example, the length of the region to be formed in a small diameter on the fingertip 7 side is 1/6 or more of the finger length from the tip P (one segment L It is preferably at least one minute, and at most 1⁄2 (for three line segments L) or less, particularly preferably at least 1/3 (for two line segments L).

If the length of the region to be formed to a small diameter is less than the above range, the effect of firmly fitting and fixing the region to the end of the finger can not be obtained, and the workability may be deteriorated. Moreover, when it exceeds the said range, while burdening bending of a finger | toe and workability | operativity falls, there exists a possibility that it may become difficult to attach or detach the glove 1. As shown in FIG.
2/3 circumference C ₂ position, and size of the user's hand, depending on how a finger, for example, preferably at 55mm or more in the case of the third finger, is preferably at 80mm or less.

When the circumferential length C ₂ is smaller than the above range, on the unpleasant there tightness fingers, workability load is imposed on the bending there is a risk of or become or, less likely to be attached and detached gloves 1 reduction. In addition, when it exceeds the above range, the fingertip 7 is easily displaced, and there is a possibility that the workability may be deteriorated.
The thickness of the film 3 can be set arbitrarily according to the application of the glove 1 etc. However, it is possible to improve the protection of the user's hand and to improve the workability by facilitating bending and stretching of the finger. When considering together, it is preferably 0.1 mm or more, particularly 0.2 mm or more, and preferably 2 mm or less, particularly 1.5 mm or less.

Examples of rubbers and resins that form the glove 1 include natural rubber, deproteinized natural rubber, acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), vinyl chloride resin, urethane resin And one or more kinds of various rubbers and resins such as acrylic resins.
The glove 1 can be manufactured by various methods as in the prior art.

For example, in the immersion method, a hand mold corresponding to the shape of the glove 1 is prepared, the surface of the hand mold is treated with a coagulant, and then it is dipped and pulled up in a liquid containing rubber or resin. This causes the liquid to adhere to the surface of the hand mold. Next, the liquid is solidified to form the rubber or resin film 3, and then the film 3 is peeled off from the hand mold to manufacture the glove 1.
The rubber or resin film 3 may have a single layer structure or a laminated structure of two or more layers. Moreover, you may reinforce with a fiber etc. as needed. That is, it may be a so-called support type glove in which a fibrous knitted glove and a rubber or resin film 3 are integrated.

In order to manufacture the support type glove, the dipping method described above is carried out with the knitted glove attached to the surface of the hand in advance to form a film of rubber or resin and to be integrated with the knitted glove. Just do it. In addition, a knitted glove may be adhered and integrated on the inner surface of a glove made of a rubber or resin film manufactured by a usual process.
Examples of the knitted gloves include seamless knitted gloves and knitted knitted gloves in which fibers such as cotton, nylon and polyester are knitted.

◎: It was very easy to work. Workability extremely good.
The above results are shown in Tables 1 and 2. The symbols of the subject column in the table are as follows. C ₀ indicates the perimeter of the distal interphalangeal joint of the designated finger. The parenthesis shows the position of the subject based on the result of measuring the hand shape of 400 Japanese adults.

(A) Third finger, C ₀ = 35 mm (approximate minimum value for adult females).
(B) Third finger, C ₀ = 44 mm (25th percentile approximation for adult women).
(C) Third finger, C ₀ = 47 mm (approximate adult male and female average value).
(D) Third finger, C ₀ = 51 mm (75th percentile approximate value for adult men)
(E) Third finger, C ₀ = 63 mm (approximated maximum value for adult males)
(F) First finger, C ₀ = 55 mm (approximated value of adult male and female average)
(G) Second finger, C ₀ = 46 mm (approximated value of adult male and female average)
(H) Fourth finger, C ₀ = 45 mm (approximated adult average value)
(I) Fifth finger, C ₀ = 41 mm (approximated adult average value)

From the results of the comparison of Table 2 Examples 1-4, be formed finger portion corresponding to the third finger to the shape of FIG. 2, the circumference C ₁ of the 1/6 position of the finger length from the tip of the finger portions , is less than 2/3 55% circumference C ₂ position, lowered workability or feel tightness to the fingertip, found that out prevention effect workability not be obtained decreases when it exceeds 80% The

In contrast, Table 1, Examples 1-7 of Table 2, the results of Examples 13 to 16, to form a finger part corresponding to the third finger to the shape of FIG. 2, the frequency of the said circumference C ₁ the length C ₂ of 55% or more, by a range of 80% or less, the respective characteristics has been found that both become ○ ~ ◎. According to these evaluations, it was found that the hand fit of the glove and the grip when holding an object through the glove can be improved, and the work in the gloved state can be facilitated. In addition, it has also been found that the range formed smaller than the region on the proximal end 8 side is preferably a range of 1/2 or less of the finger length from the tip P of the fingertip 7, particularly about 1/3.

In addition, according to the results of Examples 8 to 12 in Tables 1 and 2, the finger portions corresponding to the other fingers than the third finger have the shape shown in FIG. 2, or the finger portions corresponding to all the fingers are illustrated. even when the second shape, the circumference C ₁ of the circumference C ₂ of 55% or more, by a range of 80% or less, it was found that the effect equivalent to the case of the third finger are obtained.
Furthermore, according to the results of Examples 14 to 16 in Table 2, the rubber forming the glove is not limited to the natural rubber, and the same effect can be obtained with various rubbers, and the structure of the glove is also a single layer structure consisting only of a rubber film. It has been found that the same effect can be obtained even with support type gloves.
