Description

本発明は、把持柄の両側に凹凸状の把持面を設けた柄付き刃物に関するものである。 The present invention relates to a blade with a handle provided with uneven gripping surfaces on both sides of a gripping handle.

下記特許文献１で、柄１の把持部３の左右両把持面にあっては、前後方向で把持部３の頭部から尻部にわたり長手方向へ延びる複数本の横溝が設けられているとともに、上下方向で幅方向へ延びてこの横溝に対し交差して連通する複数本の縦溝が設けられ、この各縦溝間には指当て凸部が設けられている。使用時、把持部３を手で握った際、手の平が主に上記中間領域で指当て凸部に当てがわれるとともに、手指が上記頭部側領域や上記尻部側領域で横溝及び縦溝に掛けられる。
実登第３０５４７８６号公報 In the following Patent Document 1, on the left and right grip surfaces of the grip portion 3 of the handle 1, a plurality of lateral grooves extending in the longitudinal direction from the head portion of the grip portion 3 to the buttocks portion are provided in the front-rear direction. A plurality of vertical grooves extending in the vertical direction in the vertical direction and intersecting and communicating with the horizontal grooves are provided, and a finger contact protrusion is provided between the vertical grooves. In use, when gripping the grip portion 3 with a hand, the palm is mainly applied to the finger contact convex portion in the intermediate region, and the finger is formed into a lateral groove and a vertical groove in the head side region and the hip side region. It is hung.
JITTO No.3054786

しかし、左右両把持面の頭部側領域と尻部側領域と中間領域とにおいてはいずれも、互いに隣接する前後両縦溝間の前後方向間隔、すなわち、指当て凸部の前後方向寸法は、互いに等しく設定されているので、中間領域で指当て凸部の前後方向寸法が比較的小さくなり易く、頭部側領域や尻部側領域で縦溝間の前後方向間隔が比較的大きくなリ易い。そのため、把持部３を手で握った際、指当て凸部に接触する手の平の把持感触が悪くなるとともに、手指が横溝及び縦溝に掛かりにくくなる。従って、刃物の使い勝手が悪くなる。 However, in both the head side region, the buttocks side region, and the intermediate region of both the left and right gripping surfaces, the front-rear direction interval between the front and rear longitudinal grooves adjacent to each other, that is, the front-rear direction dimension of the finger contact convex portion is Since they are set to be equal to each other, the front-rear dimension of the finger contact projection is likely to be relatively small in the intermediate area, and the front-rear distance between the longitudinal grooves is likely to be relatively large in the head-side area and the butt-side area. . Therefore, when gripping the grip portion 3 with a hand, the grip feeling of the palm contacting the finger contact convex portion is deteriorated, and the finger is less likely to get caught in the horizontal groove and the vertical groove. Therefore, the usability of the blade is deteriorated.

この発明は、把持面の凹凸形状を改良して刃物の使い勝手を良くすることを目的としている。 An object of the present invention is to improve the concavo-convex shape of the gripping surface and improve the usability of the blade.

請求項１の発明では、把持柄（１）を手で握った際、手の平が主に上記後側領域（Ｒ，Ｑ）の隣接領域部分（Ｒ）で指当て凸部（２２）に当てがわれるとともに、手指が例えば上記頭部側領域（Ｐ）で横溝（１３，１４）及び縦溝（１５）に掛けられる。請求項２の発明では、把持柄（１）を手で握った際、手の平が主に上記前側領域（Ｒ，Ｐ）の隣接領域部分（Ｒ）で指当て凸部（２２）に当てがわれるとともに、手指が例えば上記尻部側領域（８）で横溝（１３，１４）及び縦溝（１６）に掛けられる。請求項３の発明では、把持柄（１）を手で握った際、手の平が主に上記中間領域（Ｒ）で指当て凸部（２２）に当てがわれるとともに、手指が例えば上記頭部側領域（Ｐ）または上記尻部側領域（Ｑ）または頭部側及び尻部側の両領域（Ｐ，Ｑ）で横溝（１３，１４）及び縦溝（１５，１６，１７）に掛けられる。前記隣接領域部分（Ｒ）や中間領域（Ｒ）では縦溝（１７）間の前後方向間隔（Ｌ１７）が大きくなって指当て凸部（２２）における前後方向（Ｘ）の寸法が大きくなるので、把持柄（１）を手で握った際、手の平がこの指当て凸部（２２）に接触して把持感触が良くなる。また、前記頭部側領域（Ｐ）や尻部側領域（Ｑ）では縦溝（１５，１６）間の前後方向間隔（Ｌ１５，Ｌ１６）が小さくなるので、把持柄（１）を手で握った際、手指が横溝（１３，１４）及び縦溝（１５，１６）に掛かり易くなって確実にかつ安定して把持することができる。 In the invention of claim 1, when the gripping handle (1) is gripped by the hand, the palm is applied to the finger contact convex portion (22) mainly at the adjacent region portion (R) of the rear region (R, Q). At the same time, fingers are hung on the lateral grooves (13, 14) and the longitudinal grooves (15) in the head side region (P), for example. In the invention of claim 2, when the grip handle (1) is gripped by the hand, the palm is applied to the finger contact convex portion (22) mainly at the adjacent region portion (R) of the front region (R, P). At the same time, the fingers are hung on the lateral grooves (13, 14) and the vertical grooves (16) in, for example, the hip region (8). In the invention of claim 3, when the grip handle (1) is grasped with a hand, the palm is mainly applied to the finger contact projection (22) in the intermediate region (R), and the finger is, for example, the head side. The horizontal groove (13, 14) and the vertical groove (15, 16, 17) are hung in the region (P) or the hip region (Q) or both the head and hip regions (P, Q). In the adjacent region portion (R) and the intermediate region (R), the front-rear direction interval (L17) between the longitudinal grooves (17) is increased, and the dimension in the front-rear direction (X) of the finger contact convex portion (22) is increased. When the gripping handle (1) is gripped by the hand, the palm of the hand comes into contact with the finger contact convex portion (22), and the gripping feeling is improved. Further, in the head side region (P) and the buttocks side region (Q), since the longitudinal interval (L15, L16) between the longitudinal grooves (15, 16) is small, the grip handle (1) is gripped by hand. In this case, the fingers are easily caught in the lateral grooves (13, 14) and the vertical grooves (15, 16), and can be gripped reliably and stably.

従って、請求項１〜３の発明では、刃物の使い勝手を良くすることができる。さらに、横溝（１３，１４）と縦溝（１５，１６，１７）とは縦横へ一連に延びて交差部（１８）で互いに連通するので、把持柄（１）の把持面（１２）に溜まった水分の流れが良くなって水分を把持面（１２）から排出し易くなる。 Therefore, in the first to third aspects of the invention, the usability of the blade can be improved. Furthermore, since the horizontal grooves (13, 14) and the vertical grooves (15, 16, 17) extend in series in the vertical and horizontal directions and communicate with each other at the intersection (18), they accumulate on the gripping surface (12) of the grip handle (1). As a result, the flow of moisture is improved and the moisture can be easily discharged from the gripping surface (12).
