  However, in the conventional gripping structure for a hand-held device, the spoon can be fixed in a desired direction by directing the spoon. However, the structure is complicated as a whole and needs to be essentially made of metal or resin. There is a problem that lacks. In addition, since the grip body has a simple cylindrical shape, there is a problem that it is difficult for an infant or a handicapped person to accurately grasp the spoon. The present invention has been made to solve such a problem.

  The tableware according to the present invention is configured by being cut out of wood, has a lower straight portion that is long in one direction and has a lower straight portion on the lower side, and has an upper curved portion having a curved shape on the upper side thereof, A main body gripping portion having a lower concave portion at one end side of the side linear portion, and a connecting portion provided at the one end side of the main body gripping portion, with respect to an axis in a longitudinal direction of the main body gripping portion at least 30 degrees or more. And an action part inserted and fixed at an angle of less than or equal to the degree.

  The upper curved portion may have a depressed portion formed by depressing a portion of an index finger to which a force is easily applied. Preferably, the upper curved portion has a curved shape along an arch formed entirely from the palm and the base of each finger. Further, it is preferable that the main body grip portion has a rectangular cross section.

The spoon 100 includes a main body gripping portion 1 that is gripped by a user, and a scooping portion 2 that is an operation portion that performs an essential scooping action of the spoon 100.

  The main body gripping portion 1 is manufactured by shaving wood such as bamboo, cherry blossoms, zelkova, oak, oak, cypress, chestnut, persimmon, and cedar, and is integrally formed. At this time, it is manufactured so that the grain is projected in the longitudinal direction of the main body holding portion 1. Further, the main body gripping portion 1 may be manufactured by laminating the above-mentioned wood pieces, pressing them by a predetermined adhesive, and cutting out the pressed material. In that case, it is preferable to stack the layers in order so that the grain is alternated. In addition, the upper and lower surfaces are laminated so that a grain is exposed in the longitudinal direction of the main body holding portion 1. By laminating and crimping with the wood grain directions alternately, sufficient strength and texture of the wood can be expressed, and the direction dependency of the material at the time of machining can be suppressed low.

The main body gripping portion 1 has a substantially rectangular cross section. The main body gripping portion 1 has a shape that is long in one direction and is substantially linear (a flat surface on the lower side) on the lower side in a plan view, and is gripped by a palm. An upper curved portion 11 having a gentle curvature (curved surface on the upper surface) and being held near the base of the finger of the hand, and a concave portion formed at one lower end portion in the plan view, And a connecting portion 13 provided at the one end portion for inserting and fixing the end portion 21 of the scooping portion 2.

  The lower straight portion 10 has sharp corners and a substantially rectangular cross section. The rectangular cross-section guides the gripping of the hand in a semi-compulsive manner to a predetermined gripping style. Specifically, when the thumb is pressed against the lower recess 12, the palm is positioned on the side surface portion 14, and the finger is positioned on the opposite side surface 15, so that the user can hold the thumb firmly.

 As shown in FIG. 4 (b), the upper curved portion 11 has an arch shape (indicated by the symbol A in the figure) formed by the palm and the base of each finger as a whole. It is formed by a curved shape. The width of the upper curved portion 11 is determined according to the size of a hand of a general infant to an elementary school student. By bending, the position from the index finger to the little finger is naturally corrected, so that the finger can be grasped at the correct position. In other words, the upper curved portion 11 has a shape substantially the same as the arch shape of the palm and the base portion formed inside when an average child from 1 year old to an elementary school student holds the hand H. is there.

  From another viewpoint, the upper curved portion 11 has a shape in which a portion of the forefinger to which force is easily applied is depressed (a depressed portion 16). Thereby, the shape of the upper curved portion 11 and the lower concave portion 12 described later are firmly gripped with the thumb and the index finger, which are easy to enter, so that it is possible to make the shape less slippery.

The upper curved portion 11 does not have to have the same radius, and may have a curvature that changes as long as it is curved as a whole. Further, the waveform may be such that each finger is fitted (not shown).

The lower concave portion 12 is formed as a semi-cylindrical surface on one end side of the lower linear portion 11, and has a concave curvature such that an average of an infant from one year old to a belly of an elementary school child fits. By forming the lower concave portion 12 at this position, the main body grip portion 1 is gripped, and when the thumb is fitted to the lower concave portion 12, the scooping portion 2 described later is in a correct position with respect to the hand, Naturally, the way of gripping the main body gripping portion 1 is formed. When the thumb is fitted to the lower concave portion 12, the lower portion of the palm contacts the side portion 14 of the main body grip portion 1, the vicinity of the base of the finger from the center of the palm contacts the side portion 14, and the finger is bent upward. 11, and it is natural to grip the main body grip 1 as a whole.

As described above, the lower concave portion 12 has a function of determining an overall grip angle (an angle in the circumferential direction with respect to the axial direction of the main body grip portion 1). In other words, the lower recess 12 determines the angle of the scooping unit 2 so that the angle of the face surface is determined by the grip angle of the grip of the tennis racket.

  The connecting portion 13 has a structure in which the end portion 21 of the scooping portion 2 is inserted and fixed. Specifically, a square hole 22 is provided in the side surface portion 14 at one end portion, and the scooping portion 2 The end 21 is press-fitted. The depth of the hole is about 8 mm. This hole 22 is formed by machining using a dedicated drill blade. As shown in FIG. 5, the attachment angle of the scooping unit 2 by the connecting unit 13 is set to 45 degrees with respect to the longitudinal center axis L1 of the main body gripping unit 1. The attachment angle can be 30 degrees or more and 60 degrees or less. Thereby, as shown in FIG. 4, when the infant or elementary school student holds the main body gripping portion 1 in the hand H and brings the spoon 100 close to the mouth M, the scooping portion 2 enters substantially straight with respect to the mouth M. More preferably, the attachment angle of the scooping portion 2 by the connecting portion 13 is 35 degrees or more and 55 degrees or less with respect to the longitudinal center axis L1 of the main body holding portion 1. In this way, when the infant or elementary school student naturally holds the main body gripping portion 1, the scooping portion 2 enters the mouth M more straightly.

  The connecting portion 13 has an arc portion 18 bulging upward in an arc shape. From another point of view, the arc portion 18 protrudes in a protruding shape adjacent to the upper curved portion 11. When the user grasps the arc portion 18 of the connecting portion 13, there is a sense of incongruity. Therefore, the user avoids the arc portion 18 and fits the thumb into the lower concave portion 12 and holds the thumb. You will come out from the left side. That is, the arc portion 18 acts so as to grip the hand H at a correct position.

  Next, the scooping portion 2 has a spoon portion 22 at the front end and an insertion portion 21 at the rear end. The scooping section 2 has a structure in which the above-mentioned wood pieces are laminated and pressure-bonded with a predetermined adhesive. The boundaries between the layers are formed on the upper and lower surfaces of the scooping section 2 in the longitudinal direction. In other words, a lamination surface is formed in the thickness direction of the scooping unit 2. When wood is laminated so as to form a laminated surface in the direction perpendicular to the thickness direction (plane direction), warping may occur and the wood may be deformed. Therefore, the laminated materials should be laminated so as to form the laminated surface in the thickness direction. (The layers are sequentially stacked so that the warp directions are opposite to each other), the entire warp can be suppressed, the deformation can be suppressed, and the direction dependency of the material at the time of machining can be suppressed low.

  The dimensions of the spoon portion 22 of the scooping portion 2 are adapted to the mouths of an average one-year-old infant and elementary school student. The general spoon portion 22 has an egg shape, but is not limited thereto. In addition, a fork other than the scooping section 2 may be used as the action section (not shown).

  Further, the grain of the spoon 100 as a whole appears in the longitudinal direction to form a natural image. In addition, by configuring the main body gripping portion 1 and the scooping portion 2 as separate components as a whole of the spoon 100, each of the portions to be actually held and the portions to be eaten, such as using different colors or adopting different woodgrain colors, can be used. And make it easy for elementary school students to understand. The curve 23 at the tip of the spoon 100 has a gentle curvature so that food can be easily scooped on the tableware.

  The number of layers of the wood is six. This number of layers is optimal for increasing strength and processing accuracy. In addition, since the number of layers is large, it can be evaluated as a material having uniform mechanical properties as a whole, and deformation can be minimized.

  FIG. 5 and FIG. 6 are explanatory diagrams showing functions provided by the spoon shown in FIG. As shown in FIG. 5, the longitudinal axis L1 of the main body gripping portion 1 intersects with the longitudinal extension line L2 of the scooping portion 2 at an angle of 45 degrees. Assuming that the main body gripping portion 1 is an emphasis point, the scooping portion 2 is an action point, and the connecting portion 13 between the scooping portion 2 and the main body gripping portion 1 is a fulcrum, the fulcrum is centered by slightly rotating the main body gripping portion 1 as the emphasis As a result, the tip of the scooping portion 2 acting as an action point moves greatly. Due to the principle of leverage, no extra force is required when scooping food, and fine movements are easily transmitted.

As shown in FIG. 6, the longitudinal axis L1 of the main body gripping portion 1 is substantially orthogonal to the extension line L3 in the direction of the hand, and furthermore, at an angle of 45 degrees with the extension line L2 in the longitudinal direction of the scooping portion 2. Intersect. This angle is an angle at which the scooping unit 2 enters straight into the mouth when the body gripping unit 1 is gripped by hand and the hand naturally comes close to the mouth. Also, when the wrist twisting operation cannot be performed well, the operation of scooping the food and carrying it to the mouth can be naturally performed only by the movement of the elbow and the shoulder.

  As described above, according to the spoon 100 according to the present invention, it is suitable for use by infants from the age of one and a half who start practicing the spoon and those who have difficulty moving their hands. Further, since the whole is made of wood, a natural feeling is obtained and safety is enhanced.

  FIG. 7 is an explanatory diagram showing the dimensions of the embodiment of the spoon 100. By producing the spoon 100 with the dimensions shown in FIG.
