[0011] First Embodiment Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
[0012] In FIG. 1, reference numeral 1 denotes a gripping correction device according to a first embodiment of the present invention.
[0013] This gripping corrector 1 is used by being detachably attached to a shaft-shaped writing implement (something to be held) 2 having, for example, a hexagonal cross section, and has a main body 3 into which the writing implement 2 can be fitted.
[0014] The main body 3 is formed in the shape of a straight triangular cylinder made of soft material such as silicone or plastic, and is configured to fit the writing implement 2 inside along the axial direction.
[0015] That is, as shown in Figures 2 and 3, the main body 3 has a first surface 4, a second surface 5, and a third surface 6 that form a triangular cylindrical shape, and the radial cross-sectional lengths of the first surface 4, the second surface 5, and the third surface 6 are equal, forming a cross-sectional equilateral triangle.
[0016] Furthermore, the third surface 6 is formed in a flat shape, and the first surface 4 and the second surface 5 are formed in a curved shape whose radial cross section is curved inward.
[0017] Furthermore, due to the curved shapes of the first surface 4 and the second surface 5, the main body 3 is formed such that the angle a at which the first surface 4 intersects with the second surface 5, the angle b at which the second surface 5 intersects with the third surface 6, and the angle c at which the first surface 4 intersects with the third surface 6 are all less than 60 degrees.
[0018] When using the grip corrector 1 configured in this manner, the writing implement 2 is first fitted inside the main body 3.
[0019] At this time, the first surface 4 and the second surface 5 are formed into a curved shape in which the radial cross section curves inward, so that the first surface 4, the second surface 5, and the third surface 6 are pressed against the writing instrument 2 as shown in Figure 4, thereby enabling the writing instrument to be firmly attached and less likely to come loose.
[0020] Next, the main body 3 is grasped so that the flat third surface 6 is supported by the middle finger, the curved first surface 4 is pressed by the thumb, and the curved second surface 5 is pressed by the index finger.
[0021] At this time, since the third surface 6 is formed in a flat shape, it is easy to support it with the middle finger.
[0022] In addition, since the first surface 4 and the second surface 5 are formed in a curved shape, they fit easily with the thumb and index finger.
[0023] In this embodiment, the main body 3 is formed to have an equilateral triangular cross section in which the first surface 4, the second surface 5, and the third surface 6 have equal radial cross-sectional lengths. However, for example, the main body 3 may be formed to have an isosceles triangular cross section in which the first surface 4 and the second surface 5 have equal radial cross-sectional lengths. In short, the present invention is not limited to these, and it is sufficient if the cross section is triangular.
[0024] FIG. 5 shows the state in which the grip corrector 1 is attached to chopsticks (an object to be held) 7 having a substantially square cross section in the radial direction.
[0025] Furthermore, the objects to be held are not limited to writing implements or chopsticks, and the present invention can of course also be applied to objects such as spoons and forks.
[0026] <Second embodiment> Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.
[0027] In the second embodiment, as shown in Figs. 6 to 8, the main body 3 of the holding style corrector 1 has an insertion portion 12 adjacent to the third surface 6 for inserting a flat plate-shaped, for example, spoon handle (object to be held) 11.
[0028] In addition, the same components as those in the above-described first embodiment are denoted by the same reference numerals and the description thereof will be omitted.
[0029] With this configuration, not only can the same effect as in the first embodiment be achieved, but also it is possible to use items such as a writing utensil 2, chopsticks, spoon, fork, etc. that can be fitted inside the main body 3, and it is also possible to attach a flat handle (item to be held) 11, for example a spoon, to the insertion portion 12 and use it.
[0030] <Third embodiment> Hereinafter, a third embodiment of the present invention will be described with reference to the drawings.
[0031] In this third embodiment, as shown in Figures 9 to 11, the main body 3 of the holding style correction device 1 has a first surface 4, a second surface 5 and a third surface 6 each formed of an elastic rigid member 21 such as a metal, and a flexible member 22 such as a silicone resin that covers this rigid member 21.
[0032] The first surface 4 is formed so that its radial cross section is curved inward, and the second surface 5 and the third surface 6 are formed so as to be flat.
[0033] Furthermore, the main body 3 is configured such that a slit 23 is formed between the second surface 5 and the third surface 6, and the second surface 5 and the third surface 6 are elastically pressed against each other in a direction closing the slit 23.
[0034] Furthermore, as shown in Figs. 12 and 13, the main body 3 is provided with a pair of handles 24 for widening the slit 23 against an elastic force.
[0035] The handle 24 is rotatably supported by a pair of hinge portions 25 provided at the tip end of the first surface 4 and the tip end of the third surface 6 .
[0036] Further, the main body 3 is formed such that the second surface 5 and the third surface 6 have a cross section in the radial direction that has the same length and have an isosceles triangular shape.
[0037] Furthermore, the main body 3 is formed so that the angle a at which the first surface 4 intersects with the second surface 5 and the angle c at which the first surface 4 intersects with the third surface 6 are greater than 60 degrees, and the angle b at which the second surface 5 intersects with the third surface 6 is less than 60 degrees.
[0038] When using the gripping corrector 1 configured in this manner, first, the pair of handles 24 are pinched to widen the slit 23, and the writing implement 2 is then fitted inside the main body 3.
[0039] At this time, the curvature of the first surface 4 becomes even larger, and as shown in Figure 13, the first surface 4, the second surface 5, and the third surface 6 are pressed against the writing instrument 2, so that the writing instrument can be firmly attached to the writing instrument 2 and is less likely to come loose.
[0040] Next, as shown in FIG. 9, the main body 3 is grasped so that the flat third surface 6 is supported by the middle finger, the curved first surface 4 is pressed by the thumb, and the flat second surface 5 is pressed by the index finger.
[0041] At this time, since the third surface 6 is formed in a flat shape, it is easy to support it with the middle finger.
[0042] In addition, since the first surface 4 is formed in a curved shape, it is easy to press it down with the index finger in a fitted state.
[0043] Furthermore, with this configuration, instead of the writing implement (object to be held) 2, it can also be attached to a flat plate-shaped object, for example, a spoon handle (object to be held) 11, as shown in Figs.
[0044] That is, it can be inserted into slit 23 and held between second surface 5 and third surface 6.
[0045] In this embodiment, the main body 3 is formed into an isosceles triangular cross section in which the radial cross sections of the second surface 5 and the third surface 6 are equal in length, but the main body 3 may be formed into an equilateral triangular cross section in which the radial cross sections of the first surface 4, the second surface 5 and the third surface 6 are equal in length.
[0046] Furthermore, the main body 3 is formed so that the angle a at which the first surface 4 and the second surface 5 intersect and the angle c at which the first surface 4 and the third surface 6 intersect are greater than 60 degrees, and the angle b at which the second surface 5 and the third surface 6 intersect are less than 60 degrees. However, by increasing the curvature of the first surface 4, the angle a at which the first surface 4 and the second surface 5 intersect, the angle b at which the second surface 5 and the third surface 6 intersect, and the angle c at which the first surface and the third surface intersect may be formed so as to be less than 60 degrees.
[0047] In the second and third embodiments, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted.
[0048] The disclosure regarding the present invention described above can be summarized at least as follows.
[0049] In other words, the gripping correction device of the present invention is tubular in shape with a triangular cross-section having first, second and third sides, and comprises a main body into which an object to be held is fitted, and at least one of the first, second and third sides is formed into a curved shape whose radial cross-section curves inward.
