Abstract
본 발명은 잔디를 편안한 자세로 서서 능률적으로 고르게 깎을 수 있게 한 잔디가위에 관한 것이다.The present invention relates to lawn shears that enable efficient lawn mowing while standing in a comfortable position.
양손을 사용하여 잔디를 고르게 깎는 종래의 잔디가위는 자루의 길이가 30㎝ ~ 40㎝ 정도로 짧고, 절단칼과 자루의 꺽임 각도가 약 20°전후이므로 작업자가 쪼구려 앉거나 허리를 구부린 자세로 잔디를 깎게되므로 작업이 힘들고 능률이 떨어지며, 또한 양 손으로 가위를 들어 가위와 지면 사이에 일정높이를 유지하면서 가위질 하였으므로 가위가 갖는 자중에 의해 작업자의 팔이 아플 뿐 아니라 지면이 평탄하더라도 잔디가 일정 높이로 균일하게 깎이지 않는 문제점이 있었다.Conventional lawn shears that use both hands to mow the lawn evenly have a length of about 30 cm to 40 cm, and the angle of cutting knife and bag is about 20 °, so the worker squats or bends the grass. Since the work is difficult and less efficient, and the scissors are held while holding the scissors with both hands while maintaining a constant height between the scissors and the ground, the weight of the scissors hurts the worker's arm and the grass is raised even when the ground is flat. There was a problem that does not cut evenly.
또한, 한 쌍으로 구성 된 좌ㆍ우측 절단칼의 칼날이 일직선이어서 절단칼을 오무리는 경우 경사지게 접근하는 한 쌍의 절단칼에 의해 잔디가 칼날의 선단으로 미끄러지므로 절단효율이 떨어져 작업성이 나빠지는 등의 문제점이 있었다.In addition, when the blades of a pair of left and right cutting knives are in a straight line and the knife is closed, a pair of cutting knives approaching inclinedly cause the grass to slide to the tip of the blade, resulting in poor cutting efficiency and poor workability. There was such a problem.
따라서, 본 발명은 잔디가위의 자루를 서서 작동할 수 있게 길게 연장 형성하고, 칼날과 자루의 꺾임각도를 35°~ 50°범위로 하여 잔디를 편안한 자세로 서서 깎을 수 있도록 하고, 일측 절단칼의 저부면에 360°회전되고 완충수단을 갖는 캐스터를 설치하여 잔디가위의 자중을 지면에 얹어 주행시키면서 잔디를 고르게 깎을 수 있게 하고, 일측 절단칼 또는 양측 절단칼의 칼날 부분에 완만한 곡선의 요입칼과 돌출부를 복수 개 형성하여 잔디가 칼날의 선단으로 미끄러지는 것을 방지하도록 함으로써 작업성과 작업능률을 향상시키도록 한 것이다.Therefore, the present invention is formed to extend the length of the lawn shears to operate the scissors, the angle of bending of the blade and the sack in the range of 35 ° to 50 ° so that the grass can be cut in a comfortable posture, the cutting of one side of the knife A caster with 360 ° rotation and cushioning means is installed on the bottom surface to allow the lawn shears to be cut evenly while driving the weight of the grass shears on the ground. By forming a plurality of protrusions and to prevent the grass from sliding to the tip of the blade to improve the workability and work efficiency.
Description
본 발명은 잔디를 편안한 자세로 서서 능률적으로 고르게 깎을 수 있게 한 잔디가위에 관한 것이다.The present invention relates to lawn shears that enable efficient lawn mowing while standing in a comfortable position.
일반적으로 양손을 사용하여 잔디를 고르게 깎는 종래의 잔디가위는 도 1에 도시한 바와 같이 자루(4)(6)의 길이가 30㎝ ~ 40㎝ 정도로 짧을 뿐 아니라 절단칼(12)(14)과 자루(4)(6)의 꺽임 각도가 약 20°전후이므로 작업자가 쪼구려 앉거나 허리를 구부린 채로 잔디를 깎았으므로 작업이 힘들고 능률이 떨어지는 문제점이 있었다.In general, conventional lawn shears that use both hands to mow the lawn evenly, as shown in FIG. 1, the length of the sacks 4 and 6 is about 30 cm to 40 cm, as well as the cutting knives 12 and 14. Since the angle of bending of the bag (4) (6) is about 20 ° back and forth, the worker was squatting or mowing the grass while bending the waist, the work was difficult and the efficiency was reduced.
또한, 가위와 지면 사이에 일정높이가 유지되도록 두 손으로 가위를 든 채로 가위질하였으므로 가위가 갖는 자중에 의해 가위질하는 작업자의 팔이 아플 뿐 가위의 유도이 심하여 잔디가 일정 높이로 고르게 깎이지 않는 문제점이 있었다.In addition, since the scissors were held with both hands so that a certain height was maintained between the scissors and the ground, the worker's arm hurts due to the weight of the scissors, and the guide was severely induced so that the grass was not cut evenly to a certain height. there was.
또한, 한 쌍으로 구성 된 좌ㆍ우측 절단칼의 칼날(8)(10) 부분이 일직선이므로 잔디를 깎기 위하여 절단칼(12)(14)을 오무리는 경우 경사지게 접근하는 한 쌍의 칼날(8)(10)에 의해 잔디가 절단칼(12)(14)의 선단으로 미끄러지게 되므로 절단효율이 떨어지고 작업성이 나빠지는 등의 문제점이 있었다.In addition, a pair of blades (8) and (10) of the left and right cutting knife composed of a pair is straight, so when cutting the cutting knife (12) (14) to mow the grass a pair of blades approaching obliquely (8) The grass 10 slides to the tips of the cutting knives 12 and 14, thereby reducing cutting efficiency and worsening workability.
따라서, 본 발명은 잔디가위의 자루를 길게 연장 형성하여 선 채로 잡을 수 있게 하고, 칼날과 자루의 꺾임각도를 35°~ 50°범위로 하여 잔디를 편안한 자세로 서서 깎을 수 있게 함을 목적으로 한다.Accordingly, an object of the present invention is to extend the handle of the grass shears to form a long hold, and to set the angle of bending of the blade and the sack in the range of 35 ° to 50 ° so that the lawn can be mowed while standing in a comfortable position. .
또한, 일측 절단칼의 저부면에 360°평면 회전되고 완충수단을 갖는 캐스터를 설치하여 잔디가위의 자중을 지면에 실어 주행시키면서 잔디를 고른높이로 깎을 수 있게 함을 목적으로 한다.In addition, by installing a caster having a 360 ° plane rotated on the bottom surface of one side cutting knife having a cushioning means to carry the self-weight of the lawn shears on the ground, so that the lawn can be mowed at an even height.
또한, 일측 절단칼 또는 양측 절단칼의 칼날 부분에 완만한 곡선의 요입칼과 돌출부를 복수 개 형성하여 잔디가 칼날의 선단으로 미끄러지는 것을 방지함으로써 작업능률을 향상시키도록 함을 목적으로 한다. 이하 본 발명의 바람직한 실시 예를 첨부한 도면에 따라 상세히 설명하면 다음과 같다.In addition, it is an object to improve the work efficiency by preventing the grass from slipping to the tip of the blade by forming a plurality of gentle curved indentation knife and protrusions on the blade portion of one side cutting knife or both side cutting knife.

도 2는 본 발명 잔디가위(2)의 외관 사시도로, 자루(4)(6)와 칼날(8)(10)을 갖는 한 쌍의 절단칼(12)(14)을 X 형상으로 교차시킨 다음 핀(16)으로 축 고정하여서 된 잔디가위에 있어서, 자루(4)(6)의 길이를 약 1m 전후가 되도록 길게 연장시키고, 절단칼(12)(14)과 자루(4)(6)의 꺾임각도(θ)는 도 3과 같이 35° ~ 50°범위로 유지되게 절곡시켜 잔디가위(2)를 편안한 자세로 서서 조작할 수 있도록 한다.2 is an external perspective view of the lawn shears 2 of the present invention, in which a pair of cutting knives 12, 14 having a bag 4, 6 and a blade 8, 10 are crossed in an X shape. In the lawn shears axially fixed with the pins 16, the length of the bag 4, 6 is extended to be about 1 m, and the cutting knives 12, 14 and the bag 4, 6 The bending angle θ is bent so as to be maintained in the range of 35 ° to 50 ° as shown in FIG. 3 so that the lawn shears 2 can be operated while standing in a comfortable posture.
상기에서 길게 연장시키는 자루(4)(6)는 알미늄 파이프와 같이 무게가 가벼우면서 충분한 강도가 유지되는 재질을 사용함이 바람직하며, 자루(4)(6)의 말단부에 결합 고정되는 손잡이(18)(20)의 외면은 거칠게 가공하거나 또는 요철(22)(24)을 형성하여 파지한 손의 미끄러짐을 방지하도록 한다.The long extending bag (4) (6) is preferably made of a material that is light in weight and maintains sufficient strength, such as aluminum pipe, handle 18 is coupled to the end of the bag (4) (6) The outer surface of the 20 may be roughened or the unevenness 22 or 24 may be formed to prevent slippage of the gripped hand.
한편, 일측 절단칼(12)에는 도 4와 같이 축공(26)을 형성한 다음 지면(28)으로부터 자루(4)(6)로 전달되는 진동이나 충격력을 흡수하는 완충 스프링(30)이 끼워진 캐스터(32)의 축봉(34)을 삽입 고정시켜 평면적으로 360°자유로이 회전할 수 있게 한다.On the other hand, the one side cutting knife 12 is formed with a shaft hole 26, as shown in Figure 4, the caster is fitted with a buffer spring 30 to absorb the vibration or impact force transmitted from the ground 28 to the bag (4) (6) The shaft bar 34 of 32 is inserted and fixed so as to be able to rotate 360 degrees freely in a plane.
상기에서 지면(28)과 접촉하는 캐스터(32)에 의해 잔디가위(2)의 중량이 지면(28)으로 대부분 전달되므로 잔디가위(2)를 들 필요없이 잡고 작업하면 되며, 따라서 자루(4)(6)를 밀어 주행하면서 가위질하여 잔디를 깎으면 되므로 작업이 한결 수월해지며, 또한 캐스터(32)에 의해 지면(28)과 절단칼(12)(14)과의 일정높이가 유지되므로 고른 높이로 잔디를 절단할 수 있다.Since the weight of the lawn shears 2 is mostly transmitted to the ground 28 by the casters 32 in contact with the ground 28, the grass shears 2 need not be lifted, and thus the handle 4 may be carried. (6) It is easy to work because the shearing and mowing the grass while driving, and also the fixed height between the ground 28 and the cutting knife (12) (14) by the caster 32 is maintained at an even height You can cut the grass.
또한, 상기 캐스터(32)는 평면적으로 360°자유로이 회전하므로 작업방향이나 잔디가위(2)를 원하는 방향으로 자연스럽게 주행시키면서 작업을 할 수 있다.In addition, since the caster 32 is rotated freely in a plane of 360 ° in plane, it is possible to work while driving the work direction or the lawn shears 2 naturally in the desired direction.
또한, 스프링(30)의 탄성 유격에 의해 도 4와 같이 상ㆍ하 방향 및 주행방향으로 경사 유격이 있으므로 진동이나 충격력이 흡수되어 손잡이(4)(6)로는 거의 전달되지 아니하므로 피로감을 줄일 수 있다.In addition, since the spring 30 has an inclined play in the up and down direction and the driving direction as shown in FIG. 4, vibration or impact force is absorbed and hardly transmitted to the handles 4 and 6, thereby reducing fatigue. have.
또한, 일측 절단칼(12)의 칼날(8) 부분에는 그 길이에 따라 다소 달라질 수 있으나 도 2와 같이 완만한 형상의 요입칼(36)을 3개 내지 5개 정도 형성하여 요입칼(36)로 유입된 잔디가 칼날(8)의 선단으로 밀리는 것을 방지하여 절단효율을 향상시키도록 한다.In addition, the blade 8 of the one side cutting knife 12 may vary slightly depending on its length, but as shown in FIG. 2, three to five needle blades 36 having a gentle shape are formed by the needle knife 36. To prevent the grass introduced into the tip of the blade (8) to improve the cutting efficiency.
상기에서 복수 개의 요입칼(36)을 도 5와 같이 일측 절단칼(12) 뿐만 아니라 타측 절단칼(14)에도 형성할 수 있으며, 이러한 경우 요입칼(38)과 요입칼(36) 사이로 유입된 잔디가 요입칼(36)(38)의 마디 부분에 형성된 돌출부(40)(42)의 저항에 의해 잔디가 칼날(12)(14)의 선단으로 미끄러지는 것이 방지되므로 절단효율이 더욱 향상된다.In the above, a plurality of concave knives 36 may be formed on the other side cutting knife 14 as well as the one side cutting knife 12, as shown in Figure 5, in this case introduced between the concave knife 38 and the concave knife 36 Since the grass is prevented from slipping to the tip of the blades 12 and 14 by the resistance of the protrusions 40 and 42 formed in the node portions of the indentation knifes 36 and 38, the cutting efficiency is further improved.
상기에서 요입칼(36)(38)의 표면에 형성하는 절삭부(44)는 요입칼(36)(38)과 같은 형상으로 형성하여 요입칼(36)(38)이 마모되는 경우 고르게 절삭할 수 있도록 하고, 일측 절단칼(12) 또는 양측 절단칼 선단부에 통공(48)을 형성하여 벽에 고정된 못 등에 걸어 보관할 수 있도록 한다,The cutting portion 44 formed on the surface of the needle knife 36, 38 is formed in the same shape as the needle knife 36, 38 to evenly cut when the needle knife 36, 38 is worn. To form a through hole 48 on one side of the cutting knife 12 or both cutting knife tip to be stored on the nail or the like fixed to the wall,
또한, 본 발명에서 양손을 이용하여 손잡이(4)(6)의 벌림과 오무림을 반복하면서 절단작업을 할 수 있으나 도 6과 같이 통상의 전정가위 처럼 절단칼(12)(14)의 후단부에 안쪽으로 돌출되는 돌출부(50)(52)를 대칭 형성한 다음 탄지 스프링(54)을 설치하여 손잡이(22)(24)의 벌림은 스프링(54)에 의존하고, 손잡이(22)(24)의 오무림은 양손의 가압력에 의존하도록 함으로써 힘을 덜 들이면서 절단작업을 할 수 있으며, 이러한 경우 손잡이(24) 부분에 반대측 손잡이(22)를 잡아당겨 걸 수 있는 고정고리(46)를 구비하여 잔디가위(2)를 보관하거나 이동하는 경우 절단칼(12)(14)의 벌어짐을 방지하여 안전사고를 방지하도록 함이 바람직하다. 미 설명 부호 (56)은 삽지구, (58)는 캐스터의 휠, (60)은 캐스터의 브라켓, (62)는 캐스터의 축봉 이다.In addition, the present invention can be cut while repeating the opening and squeezing of the handle (4) (6) using both hands in the present invention, but the rear end of the cutting knife (12) (14) like a normal pruning shear as shown in FIG. Symmetrically forming protrusions 50 and 52 protruding inwardly, and then installing a stop spring 54 so that the opening of the handles 22 and 24 depends on the spring 54 and the handles 22 and 24. The rim of the can be cut with less effort by relying on the pressing force of both hands, in this case is provided with a fixing ring 46 that can be pulled on the opposite handle 22 on the handle 24 When the lawn shears 2 are stored or moved, it is preferable to prevent the safety accident by preventing the spread of the cutting knife 12, 14. Reference numeral 56 denotes a shovel, 58 a caster wheel, 60 a caster bracket, and 62 a caster shaft.
본 발명에서 설명의 편의상 절단 대상물로 잔디를 그 일예로 들었으나 잔디 이외의 농작물이나 각종 식물의 절단에 그대로 적용할 수 있음은 물론이다.For the convenience of description in the present invention, the grass is used as the cutting object as an example, but it can be applied to the cutting of crops and various plants other than the grass as it is.
이상과 같이 본 발명은 잔디가위(2)의 자루(4)(8)를 길게 연장 형성하고, 절단칼(12)(14)과 자루(4)(6)의 꺾임각도(θ)를 35°~ 50°범위로 하여 잔디를 편안한 자세로 서서 깎을 수 있는 효과가 있다.As described above, according to the present invention, the bag 4 and 8 of the lawn shears 2 are extended and formed, and the bending angle θ between the cutting knives 12 and 14 and the bag 4 and 6 is 35 °. It is effective to mow the grass in a comfortable position in the range of ~ 50 °.
또한, 일측 절단칼의 저부면에 360°회전되고 완충수단을 갖는 캐스터가 설치되어 있으므로 잔디가위의 자중이 지면에 실리므로 잔디가위를 가볍게 주행시키면서 고른 높이로 깎을 수 있으며, 지면으로부터 전달되는 진동이나 충격력이 흡수 되므로 작업자의 피로감을 줄일 수 있는 효과가 있다In addition, since the caster is rotated 360 ° on the bottom surface of one side cutting knife and has a cushioning means, the weight of the lawn shears is loaded on the ground, so that the lawn shears can be mowed at an even height while running lightly. Since the impact force is absorbed, there is an effect that can reduce the fatigue of the worker
또한, 일측 절단칼 또는 양측 절단칼의 칼날 부분에 복수 개의 요입칼과 돌출부가 완만하게 형성되어 있으므로 잔디가 칼날의 선단으로 미끄러지는 것이 방지되고 작업능률이 향상되는 등의 효과가 있는 유용한 발명이다.In addition, since the plurality of indentation knives and protrusions are gently formed in the blade portion of one side cutting knife or both side cutting knife, it is a useful invention that the grass is prevented from sliding to the tip of the blade and the work efficiency is improved.
