Description

  The present invention relates to a grip assisting tool that is detachably inserted into a gripping part such as a writing instrument, glue, correction tape, grudge or driver, and grips the object for easy operation.

  Conventionally, in writing instruments that contain felt in the writing part, the rear part is made spherical so that it is easy to grip for infants and the cap is easy to remove from the writing part, A constricted “shaft-shaped” writing instrument for infants is disclosed in Japanese Utility Model Publication No. Hei 3-84188, and it is known that such a shape is easy to grip. However, the disclosed technology relates to the shape of a writing instrument as a cylinder, and is inserted into a gripping part of an object such as glue, a correction tape, a grudge, or a driver to operate the object with ease. It is not intended to make it easier.

  Japanese Patent Application Laid-Open No. 2005-111959 discloses a neck in which the support body is narrower in the middle than in the upper part, so that the object can be easily gripped by being inserted into a gripping part of the object. A cylindrically-shaped “assistance tool for handicapped persons” having an outer diameter gradually increasing in diameter toward the rear end opposite to the insertion hole or having a spherical shape at the rear end side of the neck portion is disclosed. ing. This technology can be used without applying force by pinching between the thumb and another finger or between adjacent fingers, and even if there is no force applied, the finger is adjacent to another finger or adjacent Since it is sandwiched between the fingers, it is necessary to apply force to the fingers, and the fingers will have two roles of operation and gripping of the accessory, which may cause fatigue.

  Actually, many objects are designed on the premise that they are grasped by fingers, but fingers are weaker than individual functions and have less durability than repeated. When an object that is gripped with a finger is manipulated, the finger has two roles of object manipulation and gripping, which causes fatigue. In view of these facts, the inventor of the present invention provides a shape having a curved surface that can come into contact with the palm and a grip aid that is used to wrap and grip each finger and palm in order to reduce fatigue on the finger. I thought.

According to the registered utility model registration No. 3058876, a gripping portion having a curved rear end that can come into contact with the palm and formed so as to be wrapped and gripped by each finger and palm, and a predetermined portion at the tip of the gripping portion. A writing instrument characterized by comprising a pen tip extended at an angle is described, but the disclosed technique relates to a shaft cylinder of a writing instrument, and the gripping part of an object It is not intended to make it easier to grip and manipulate the object by inserting it. Moreover, since the gripping part shape in the above-mentioned device is a writing instrument, the gripping part is sandwiched with a finger so that the moving direction of the writing instrument is easy to operate, and the entire gripping part is wrapped with each finger and palm. It is hard to say that it is a shape.
Japanese Utility Model Publication No. 3-84188 JP 2005-111959 A Registered Utility Model Registration No. 3058876

  The present invention allows a person with weak pinching force at a fingertip to use a tool such as a writing tool or a correction tape, a tool such as a driver, an object such as a fork or a spoon, and hold it with a finger and a palm. An object of the present invention is to obtain a grip assisting tool for reducing fatigue and for detachably inserting it into an object.

The present invention
“1. A grip assisting tool having an opening and a cavity that are detachably inserted and held in a gripping part of an object, the shape of which is at one end in a direction along the axis. A grip aid having an oval shape with an opening, gradually tapered toward both ends, having a maximum outer diameter of 30 mm to 50 mm and a total length of 50 mm to 70 mm on the peripheral side surface .
2. 2. The grip aid according to claim 1, wherein the grip aid is provided with a through hole that communicates the cavity and the outside different from the opening.
3. The above-mentioned item 1 or 2, wherein the grip auxiliary tool is provided with a projection hole that communicates with the cavity, so that the projection formed on the object gripping part can project outward from the cavity. Auxiliary tool for grip as described.
4). 4. The grip assisting device according to any one of items 1 to 3, wherein the grip assisting device is formed of a rubber-like elastic body, a gel-like substance, or a porous body.
5. 4. The grip aid according to any one of items 1 to 3, wherein the grip aid is made of silicone rubber. "
It is.

  The grip assisting device of the present invention is formed in a substantially oval shape because the fingers of this shape are slightly curved and gripped using the finger joint, and the fingertip is slightly This is because it can be held with great force. The same thing can be said even if the shape of the grip assisting device is simply a spherical shape, but if it is a simple spherical shape, the grip assisting device will move easily in the palm of the body while operating the object, so that it will not move Since extra force is required for the fingers, it is not preferable.

  The opening of the grip assisting tool only needs to be able to be inserted into the gripping part of the object, and the shape is not particularly specified as a circular shape, a square shape, a polygonal shape or the like. A mere cut may be given.

  The grip assisting tool of the present invention is not inserted into a specified object such as a writing cylinder or the like by appropriately forming the shape and size of the opening and the cavity, and grips various objects. It is used by being detachably inserted into the part. The maximum outer diameter on the peripheral side is specified as 30 mm to 50 mm, regardless of whether the user of the grip assisting device of the present invention is young or old, and even in the lower grades of elementary school students. Is to be held with a finger and palm.

  By the way, body part measurement data by age and gender (traveled throughout Japan from 1992 to 1994 at the Human Life Engineering Research Center, measuring the physique of 34,000 people aged 7 to 90) Data) on the inner diameter (the distance of the portion L of the hand shown in FIG. 13 in the diameter of the plastic sheet when the plastic sheet is wound into a cylinder and passed through a ring made of the thumb and middle finger) Based on, in the age from almost 7 years old to 99 years old, the inner diameter size when rolling the palm and grasping something is about 30mm at the age of 7, reaching 40mm at the age of 14, and then about 40mm until the age of 99 The maximum outer diameter on the peripheral side surface is not set appropriately, but is a value supported by the data.

  Moreover, although the total length of the auxiliary tool for grips is specified as 50 mm to 70 mm, this is for enveloping the whole with each finger and palm. This is because a finger is applied to the edge of the substantially oval shape by the fingertip, and the grip aid can be operated with a slight force of the fingertip. If the total length is too long, the grip assisting tool will be gripped by each finger and palm, but the grip assisting tool will be held in a state where the finger is extended, and force must be applied to the finger. In addition, even if it is too short, the entire grip aid cannot be grasped so as to be wrapped around with fingers and palms. It will be responsible for these two roles, causing fatigue. Therefore, the total length is preferably 50 mm to 70 mm.

  According to the body part measurement data by age and gender as described above, the fingertip / finger joint distance (the straight distance between the fingertip and the finger joint on the back of the hand, the hand shown in FIG. The distance of the portion N is about 74.1 mm at the age of 7 for both men and women, and it can be seen that the distance increases gradually as the age increases. From these data, it can be seen that if the total length is 70 mm or less, both children and adults can grip the entire assisting tool for gripping with fingers and palms.

  Since the grip auxiliary tool of the present invention has a substantially oval shape within the above-mentioned size range, it can be grasped by wrapping the whole with each finger and palm, so if it is inserted into the gripping part of the object, the clamping force at the fingertip is weak Even humans can use objects. Moreover, since the force of the intensity | strength for pinching an object with a finger is not required, a specific site | part does not hurt and the feeling of fatigue to a finger and the feeling of fatigue from a hand to a shoulder can be reduced. Moreover, since it can be detachably fitted to various objects as required, it is economical.

  The effect of the invention according to claim 2 is that the grip assisting tool is inserted into the gripping part of the object by providing the grip assisting tool with a through hole that communicates the cavity and the outside different from the opening. It becomes a hole for the air change inside, and can be smoothly attached to and detached from the object.

  The effect of the invention according to claim 3 is that the grip assisting tool is provided with a projection hole that communicates with the cavity so that the projection formed on the gripping portion of the object can project outward from the cavity. Therefore, even if there is a protrusion on the part of the object where the grip auxiliary tool is inserted, the protrusion can protrude outward from the grip auxiliary tool, so it is possible to insert the grip auxiliary tool. It becomes.

  The effect of the invention according to claim 4 is that when the grip assisting device is formed of a rubber-like elastic body, a gel-like substance or a porous body, a fit feeling is obtained in combination with the shape of the grip assisting device, and it is easy to grip and fatigue. There is an advantage that it is difficult.

  The effect of the invention which concerns on Claim 5 has the advantage that it is hard to become dirty when the auxiliary tool for grips is formed with silicone rubber.
