ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a gripping glove favorably used for gripping such things as high-temperature cooking utensils in a kitchen, heat-treated members in high temperature in a factory, or high-voltage electric cables.
2. Description of the Related Art
While a pair of gloves made of thick materials are conventionally used for gripping such a thing as a heated cooking utensil up to a high temperature in a kitchen oven, that of a mitten type (refer to
FIG. 4
) employed to enable quick putting on and off of the gloves.
Namely, such a glove is in general use that has a thumb receptacle or sack portion a for putting in the thumb and a common sack portion b for putting in all other fingers together.
While the shape of above described conventional mitten-type glove enables is to be quickly put on and off, when used for gripping such things as high-temperature members and high-tension cables, it is difficult to produce a firm gripping action, and there is a tendency that the gripping action is produced only by having the common sack portion b turned down toward the palm side.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a gripping globe arranged such that a firm gripping action of a member is produced safely by the third, fourth, and fifth fingers, receiving suitable assistance in supplementing the gripping force from the thumb and the forefinger, and that the action needed to put the glove on the hand is quickly performed.
In order to attain the above mentioned object, the gripping glove of the present invention comprises a sack portion for accommodating a thumb and a sack portion for accommodating forefinger arranged independently of each other for accommodating in the thumb and the forefinger, respectively, and a common sack portion formed in a one-piece unit for accommodating the third finger, fourth finger, and fifth finger, together, arranged separately from the sack portion for the forefinger.
Further, the gripping glove of the invention is characterized by that, when it is in its non-used and flattened state, the angle formed between the center line of the sack portion for thumb and the center line or control axis of the sack portion for forefinger is set between 40 and 50° and the angle formed between the center line of the sack portion for forefinger and the center line of the common sack portion is set between 25 and 35°.
Further, the gripping glove of the invention is characterized by having surfaces processed for preventing occurrence of slippage on the palm side of the sack portions.
In the above described gripping glove of the invention, there are the sack portion for thumb and the sack portion for forefinger arranged separately from each other for putting in the thumb and the forefinger, respectively, and, in addition, a common sack portion formed in a one-piece unit for putting in the third finger, fourth finger, and fifth finger, together, arranged separately from the sack portion for the forefinger. Therefore, when used allows the user the glove to grip firmly a high-temperature member or the like with the common sack portion turned down toward the palm side. At this time, especially because the sack portion for the thumb and the sack portion for the forefinger give cooperative assistance in the gripping action, it is made possible to more firmly grip the high-temperature member, a high-tension cable, or the like. Thus, serviceability of the gripping glove of the invention becomes greatly improved.
Since, when the glove is in its non-used and flattened state, the angle formed between the center line of the sack portion for the thumb and the center line of the sack portion for the forefinger is set between 40 and 50° and the angle formed between the center line of the sack portion for the forefinger and the center line of the common sack portion is set between 25 and 35°, the relative positions of the sack portions are rendered conformable to the shapes of the fingers that are naturally opened. Hence, when the glove is used, the operation to put it on the hand with the fingers inserted into their respective sack portions can be performed quickly, and this is especially helpful for a cook when hurried during operating an oven or using a frying pan in the kitchen or for a worker when gripping a high-voltage electric cable at a height.
Further, since there are provided surfaces processed for preventing occurrence of slippage on the surface of the sack portions on the palm side, the gripping operation by the glove can be performed more firmly and this contributes to an improvement in safety.
