The present application is a continuation of International Application No. PCT/KR2011/009460 filed Dec. 8, 2011, which claims priority to Korean Application No. 10-2010-0135219 filed Dec. 27, 2010, which applications are incorporated herein by reference.
TECHNICAL FIELDThe present invention relates to a glove for gripping a small object, and more particularly, to a glove for gripping a small object having a structure of a thimble portion and a forefinger portion being able to easily grip the small object.
BACKGROUND ARTA conventional glove is used for protecting a hand or for maintaining temperature of the hand regardless of the outside temperature. Recently, a function of a glove is being expanded from the protection of the hand. Thus, various gloves such as a cut resistant glove, a non-slipping glove, a heat resistant glove, a winter glove, an acid-resistant glove, a flame resistant glove, a vibration isolation glove, a glove for treating oil and solid waste, and so on.
The glove is formed of cloth with a predetermined thickness in order to protect a hand. However, when a user works while wearing the glove, it is difficult for the user to grip small instruments, such as, a needle, a pin, a nail, a screw, and so on. Therefore, the user should take off the glove and grip the small objects with bare hands, and thus, it is inconvenient. Further, if the grip of the small object is difficult with even bare hands due to the size of the small object, an additional instrument should be prepared.
Also, an end of the conventional glove is not sharp and the conventional glove is formed of an insulating material. Thus, signal cannot be provided to a touch panel of a resistance type and a capacitance type when the user wears the glove. Accordingly, the user cannot use the touch panel while wearing the glove.
On the other hand, according to a study of the inventor, there are four reasons why the grip of the small object is difficult with the glove.
First, conventionally, the small objects are gripped by finger tips of a thumb and a forefinger. By a thickness of a glove material constituting the glove, a point of the glove where the thumb and the forefinger are in contact become stubby and a dead space of the gripping is formed.
Secondly, when the finger is inserted to a space of a glove finger portion, an extra space is formed between the glove and the hand because the glove is larger than the finger. When the end portion of the glove is in contact with the object, the extra space is folded and creases are generated, and thus, the grip of the small object is disturbed.
Thirdly, the human hand has nails. Thus, when gripping the small object of a limited size (that is, a semiconductor chip, a larva, an insect egg, and so on), the nail of the thumb and the nail of the forefinger are symmetrically positioned with respect to the small object, the grip position and the balance of the object are secured, and a proper grip force is provided to the object. However, the glove does not have the nails.
Fourthly, in order to grip the small object that the maintenance of the gripped contact point is impossible (such as, the object has a sphere shape or a round bar), the small object is raised through gripping central lower portions of the object are gripped by the nails, and then, the small object is settled between the nails and finger print portions. However, in the state that the glove is worn, the pulling the small object upward or the settlement between the nail and the fingerprint portion are impossible.
SUMMARY OF THE DISCLOSUREThe present invention has been made in view of the above problems, and the present invention provides a glove being able to easily grip small objects than bare hands of human.
Also, the present invention provides a glove being able to transfer signal to a touch panel of a resistance type and a capacitance type.

Hereinafter, with reference to accompanying drawings, examples of the present invention will be described in detail. For convenience, like reference numerals refer to like elements throughout.
With reference to
The thimble portion 10 is formed at an end portion of the finger portion of the glove. The thimble portion 10 includes a first layer 101 facing the back of a hand and a second layer 102 being opposite to the first layer 101. Front sides of the first layer 101 and the second layer 102 are adhered to each other and form a structure where the finger is inserted. In this instance, the thimble portion 10 may be inserted to the finger portion, may be adhered to the finger portion, or may be formed by an injection molding.
In this instance, in a vertical cross section taken along a longitudinal direction of the finger, the first layer 101 may be formed of a curved surface having a convex shape from an inner side of the thimble portion toward an outside of the thimble portion. A curvature of the curved surface of the first layer 101 is varied. The second layer 102 may be formed of a curved surface. The front side of the second layer 102 is convex from the outside of the thimble portion to the inner side of the thimble portion, the rear side of the second layer 102 is convex from the inner side of the thimble portion to the outside of the thimble portion, and a curvature of the second layer 102 is gradually varied between the front side of the second layer 102 and the rear side of the second layer 102. Thus, there may be an inflection portion between the front side of the second layer 102 and the rear side of the second layer 102. However, the present invention is not limited to the shapes of the first and second layers 101 and 102. The line where the front sides of the first layer 101 and the second layer 102 meet forms an edge line 103.
The thimble portions 10 corresponding to different fingers have the same shapes and structures; however, the size of the thimble portions 10 corresponding to the different fingers may be different. The thimble portion 10 may have bilateral symmetry. The thimble portion 10 of the bilateral symmetry can be easily manufactured.
As shown in
A material of the thimble portion 10 is an important factor of a gripping ratio. The first layer 101 may preferably have Shore A hardness of about 20 to about 70. In this instance, the large hardness is advantageous to easily grip an object being large and heavy. Beyond the above range, the gripping ratio is below standard of industrial utilization.
Specifically, the material of the thimble portion 10 may be selected from various materials, such as, rubber, synthetic resin, fiber, metal, non-metal, and so on. The thimble portion may be preferably formed of the material that an original form is rapidly recovered.
For example, the material of the thimble portion 10 may be manufactured to have the above hardness range, by using one rubber selected from the group consisting of nitrile rubber, natural rubber, acrylic rubber, urethane rubber, fluoro rubber, silicon rubber, and synthetic rubber thereof. However, the present invention is not limited thereto.
Beside the material, a thickness of the thimble portion 10 is also an important factor. The first layer 101 may preferably have the thickness of about 0.03 mm to about 3 mm. When the thickness of the first layer 101 is above about 3 mm, repetitive movements for gripping the object (that is, bending and spreading out the fingers) may be disturbed by the thickness of the first layer 101. When the thickness of the first layer 101 is below about 0.03 mm, a manufacture of the structure of the first layer 101 may be difficult because of the small thickness.
Also, the second layer 102 may preferably have the thickness of about 0.03 mm to about 3 mm. When the thickness of the second layer 102 is above about 3 mm, repetitive movements for gripping the object (that is, bending and spreading out the fingers) may be disturbed by the thickness of the second layer 102. When the thickness of the second layer 102 is below about 0.03 mm, a manufacture of the structure of the second layer 102 may be difficult because of the small thickness. In this instance, the second layer 102 may be thinner than the first layer 101 in order to provide a feeling like the human hand during wearing the glove.
On the other hand, the thimble portion 10 has a streamlined shape on the whole. That is, a height of the thimble portion 10 decreases as it goes toward the edge line of the front end portion, and the thickness of the edge line that is the front end is in a range from about 0.001 mm to about 0.5 mm. Hereby, the edge line of the thimble portion 10 is thinner than the nail of the human hand (for example, the thickness of the nail of the human hand is about 0.65 mm), and thus, the small object can be easily gripped through the glove more than the human hand.
A length of the thimble portion 10 may be preferably the same as a length from a fingertip to a knuckle adjacent to the fingertip of the finger, or be preferably slightly larger than a length from a fingertip to a knuckle adjacent to the fingertip of the finger.
During the gripping the object, a right-and-left center line of the nail of the thumb and a right-and-left center line of the nail of the forefinger are not arranged in a straight line in a front view. That is, an angle of the right-and-left center line of the nail of the thumb and the right-and-left center line of the nail of the forefinger is about 140°. The right-and-left center line of the nail of the thumb and the right-and-left center line of the nail of the forefinger at the gripping point are not consistent with or aligned with each other and have a gap of about 2.2 mm to about 2.9 mm. Also, a surface of the nail of the thumb and a surface of the nail of the forefinger are not aligned with each other. Accordingly, it is difficult to grip a smaller object by the human hand. Here, the right-and-left center line means a line connecting centers of the right-and-left direction.
In order to easily grip the smaller object more than the human hand, in the glove for gripping the small object according to the embodiments, a distance between the right-and-left center line of an outer surface of the first layer of the thumb thimble portion and the right-and-left center line of an outer surface of the first layer of the forefinger thimble portion are aligned with each other within an error margin of about 0 mm to about 0.5 mm, when the user wear the glove and align the front end portion of the thumb thimble portion and the front end portion of the forefinger thimble portion. Also, an angle between both the right-and-left center lines may be in a range from about 170° to about 190° in a front view where the first layers are shown. The thumb thimble portion and the forefinger thimble portion may have a common a tangent plane at the contact point of the both the right-and-left center lines.
To achieve this, the thumb thimble portion 10-1 is positioned at a position rotated to the right with respect to the nail of the thumb that the first layer 101 of the thumb thimble portion corresponds to. Also, the forefinger thimble portion 10-2 is positioned at a position rotated to the left with respect to the nail of the forefinger that the first layer 101 of the thumb thimble portion 101-2 corresponds to.
On the other hand, hereinafter, gloves according to embodiments being able to be used as stylus pens on a touch screen of a capacitance type will be described. Same reference numerals refer to elements same as or similar to the elements of the above embodiment for convenience.
In the embodiment, at least a part of a portion where a second layer 102 of a forefinger thimble portion 10-2 is mounted has a hole 201, and a finger of a user is in direct contact with the forefinger thimble portion 10. In this instance, the forefinger thimble portion includes a conductive resin, and thus, a current of the finger of the user is transferred to the touch screen through the forefinger thimble portion, thereby generating the capacitance change of the touch screen.
In this instance, widely known moldable conductive resin may be used the conductive resin. A material that a conductive metal and resin are mixed is generally used. For example, iron, cupper, nickel, and so on may be used for the metal, and PPE, PC, and so on may be used for the resin.
In the embodiment, a stylus pen is mounted on the first layer 102. That is, the stylus pen is mounted in the first layer 102. The stylus pen may be integrated with the thimble portion during an injection molding, or may be detachable to the thimble portion.
The stylus pen includes a battery 302, and a conductive tip 301 for transferring the current of the battery. Also, a connection element for connecting the battery 302 and the conductive tip 301 may be further included.
The battery 302 is a small size battery having a size being able to be included in the first layer. The conductive tip 301 has a stick shape extending in the finger direction. Also, the front end portion of the conductive tip 301 may be preferably consistent with or aligned with the front end portion of the thimble portion.
The mounting member 403 may be preferably fixed to or mounted on the thimble portion 10 through elastic deformation. The conductive tip may preferably have a long stick shape, and an end portion of the conductive tip 401 may be preferably consistent with or aligned with the end portion of the thimble portion 10. The battery 402 provides current to the conductive tip 401.
The thimble portion may be mounted on the glove main body by forming the thimble portion, coating an adhesive agent to an inner surface of the thimble portion, and adhering the thimble portion to the glove main body using the adhesive agent. Considering environmental problems, the process that does not use the adhesive agent is preferable.
A method for mounting the thimble portion on the finer portion of the glove main body by an injection molding may be useful. In this case, the method for mounting the thimble portion on the finger portion by the injection molding will be described with reference to
First, an upper the upper core 601, the lower core 602, and the slide core 603 of a molding are manufactured, respectively. The upper core 601 forms an outer surface of the first layer 101 of the thimble portion 10, the lower core 602 forms an outer surface of the second layer 102 of the thimble portion 10, and the slide core 603 is inserted into the finger portion of the glove main body 20 and forms an inner shape of the thimble portion.
That is, when the upper core 601 and the lower core 602 are open, the slide core 603 is installed between the upper core 601 and the lower core 602. In this instance, the finger portion of the glove main body 20 is installed on the slide core 603. And then, the upper core 601 and the lower core 602 are closed to be sealed. Then, an injection space is formed between the finger portion of the glove main body and the cores. The injection-molded member of high pressure is filled in the injection space, and then, the thimble portion is formed. After the injection molding, the slide core 603 is separated and the injection-molded member is taken from the slide core 603.
In this, each the upper core 601, the lower core 602, and the slide core 603 may have include protrusions 611, 613, 615, and 617 for preventing the deviation of the injection-molded member so that the injection-molded member does not stay from an area where the thimble portion 10 is formed.
On the other hand, a plurality of the cores of the molding may be used. Then, during the injection molding using one set of cores, the process putting the glove to another set of cores can be performed. Thus, the productivity can be improved.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
