Description

마찰계수 조절이 가능한 등긁개 {A backscratcher that can control the coefficient of friction}A backscratcher that can control the coefficient of friction}

본 발명은 마찰계수 조절이 가능한 등긁개에 관한 것으로, 특히 하나의 등긁개의 긁개부에 마찰계수가 다른 3개(예컨대, 마찰계수가 상, 중, 하)의 접촉면을 구비하여 사용자가 원하는 마찰계수의 접촉면를 임의로 선택하여 사용할 수 있도록 한 것이다.The present invention relates to a back scraper with an adjustable friction coefficient. In particular, the scraper portion of one back scraper is provided with three contact surfaces with different friction coefficients (e.g., high, middle, and low friction coefficients) to provide friction desired by the user. The contact surface of the coefficient can be selected and used arbitrarily.

일반적으로 등긁개는 인체의 등과 같이 손이 닿지 않는 가려운 부위를 긁어주는데 사용되는 것으로, 효자손으로 지칭되기도 한다. In general, back scratchers are used to scratch itchy parts of the body that cannot be reached, such as the back, and are also referred to as filial piety.

종래의 등긁개는 대나무 또는 합성수지 등을 사용하여 소정의 길이를 지니도록 제조되고, 등을 긁을 수 있도록 ㄱ형상으로 구비되는 긁개부와, 긁개부에서 파지가 용이하도록 하기 위한 손잡이부로 구성된다Conventional back scrapers are manufactured to have a predetermined length using bamboo or synthetic resin, etc., and consist of a scraper part provided in an L shape to scratch the back, and a handle part to facilitate gripping in the scraper part.

그러나 상기와 같은 종래의 등긁개에 있어서는, 손잡이 끝부분에 긁개부가 설치되어 있어 등을 긁을 수 있도록 되어 있으나 이러한 긁개부가 일정한 형태로만 형성되어 있는 결점이 있다.However, in the conventional back scratcher as described above, a scraper is provided at the end of the handle to enable scratching of the back, but there is a drawback in that the scraper is only formed in a certain shape.

즉, 종래에는 긁개부가 단지 사람의 손 형태를 하거나 또는 등긁개에 돌기를 형성하여 좀더 시원한 느낌을 주도록 하고 있으나, 이와 같은 등긁개가 일률적으로형성되어 있어 사용상의 불편함이 있음은 물론, 등을 긁는 강도에 변화를 줄 수 없는 결점이 있다.In other words, conventionally, the scraper is simply in the shape of a human hand or has protrusions formed on the back scraper to give a cooler feeling. However, since the back scraper is formed uniformly, it is inconvenient in use and also causes damage to the back. It has the drawback of not being able to change the scratching intensity.

도 1과 도 2는 본 발명의 마찰계수 조절이 가능한 등긁개 긁개부의 분리사시도로, 이에 도시된 바와 같이, 긁개부와 손잡이부로 구성되는 등긁개에 있어서, 상기 긁개부(1)가, 표면에 마찰계수가 다른 접촉면(2)을 가지며 내부에 길게 관통공(3)이 형성된 원형의 마찰부(4)와, 상기 마찰부(4)가 장착될 수 있도록 반원형으로 형성되며 일측에 구멍(5)이 형성되고 타측에는 구멍(6)과 다수의 걸림홈(7)이 형성된 헤드부(8)와, 상기 마찰부(4)가 상기 헤드부(8)에 장착된 상태에서 상기 관통공(3)과 구멍(5)(6)들에 삽입됨과 함께 돌기(9)가 걸림홈(7)에 걸려 고정되어 원하는 마찰부의 접촉면이 헤드부 표면에 노출되도록 하는 원형삽입축(10)을 포함하여 구성된 것으로, 도면중 미설명 부호 11은 상기 원형삽입축의 일측 끝단에 체결되는 볼트, 12는 등긁개의 손잡이부이다. Figures 1 and 2 are an exploded perspective view of the scraper portion of a back scraper with an adjustable friction coefficient of the present invention. As shown, in the back scraper consisting of a scraper portion and a handle portion, the scraper portion (1) is on the surface. A circular friction part (4) having a contact surface (2) with a different coefficient of friction and a long through hole (3) formed therein, and a semicircular shape so that the friction part (4) can be mounted, and a hole (5) on one side. A head portion (8) formed with a hole (6) and a plurality of locking grooves (7) on the other side, and the through hole (3) with the friction portion (4) mounted on the head portion (8). It is composed of a circular insertion shaft (10) that is inserted into the holes (5) and (6) and the protrusion (9) is caught and fixed in the locking groove (7) so that the contact surface of the desired friction portion is exposed to the head surface. , in the drawing, the unexplained symbol 11 is a bolt fastened to one end of the circular insertion shaft, and 12 is a handle portion of the back scraper.

상기 원형삽입축(10)의 일측 내부에는 나사부가 형성되어 상기 볼트(11)가 나사부에 나사끼우기로 결합되도록 구성된다.A threaded portion is formed on one side of the circular insertion shaft 10 so that the bolt 11 is screwed into the threaded portion.

단, 상기 접촉면(2)은, 예를 들어, 3개로 나뉘어져 마찰계수가 강한부분과 중간부분 그리고 약한부분으로 구분할 수 있는 것으로, 산업용 다이아몬드를 사용하여 형성할 수 있다.However, the contact surface 2, for example, can be divided into three parts with a strong friction coefficient, a middle part, and a weak part, and can be formed using industrial diamond.

이와 같이 구성된 본 발명의 작용을 설명한다.The operation of the present invention configured as described above will be explained.

본 발명의 등긁개는 도면과 같이 손잡이부(12)와 긁개부(1)로 구성되어 있으며, 상기 긁개부(1)가, 반원형의 헤드부(8)내에 원통형의 마찰부(4)가 장착된 구조를 갖는 것으로, 상기 마찰부(4)의 표면에는 3개의 접촉면(2)이 각각 구분되게 형성되어 있다.The back scraper of the present invention is composed of a handle portion 12 and a scraper portion 1 as shown in the drawing, and the scraper portion 1 is equipped with a cylindrical friction portion 4 within a semicircular head portion 8. It has a structure in which three contact surfaces 2 are separately formed on the surface of the friction portion 4.

즉, 헤드부(8)내에 먼저 마찰부(4)를 장착하고, 원형삽입축(10)을 헤드부(8)의 구멍(5)(6)과 마찰부(4)의 관통공(3)을 통하여 삽입하며, 마찰부(4)의 일측은 볼트(11)로 체결하고 타측은 원형삽입축(10)에 형성된 돌기(9)를 걸림홈(7)에 삽입하여 체결한다.That is, the friction part 4 is first installed in the head part 8, and the circular insertion shaft 10 is inserted through the holes 5 and 6 of the head part 8 and the through hole 3 of the friction part 4. It is inserted through, and one side of the friction part (4) is fastened with a bolt (11), and the other side is fastened by inserting the protrusion (9) formed on the circular insertion shaft (10) into the locking groove (7).

따라서, 상기 헤드부(8)내에 마찰부(4)의 상부가 노출되면서 이러한 마찰부(4) 표면에 형성된 접촉면(2)을 통하여 등을 긁을 수 있는 것이다. Accordingly, the upper part of the friction part 4 is exposed within the head part 8 and the back can be scratched through the contact surface 2 formed on the surface of the friction part 4.

이때, 상기 마찰부(4)에는 3개의 접촉면(2)이 각각 형성되어 있어 사용자가 원하는 접촉면(2)을 선택하여 사용할 수 있다.At this time, three contact surfaces 2 are formed on the friction portion 4, so the user can select and use the desired contact surface 2.

예를 들어, 등을 좀 더 강하고 시원하게 긁고자 할 경우에는, 접촉면(2)중에서 마찰계수가 제일 큰 접촉면이 헤드부(8)의 표면에 노출되도록 하여 이러한 접촉면(2)을 사용하여 등을 긁을 수 있다.For example, if you want to scratch your back more strongly and refreshingly, the contact surface with the highest coefficient of friction among the contact surfaces (2) is exposed to the surface of the head part (8) and you can scratch your back using this contact surface (2). You can.

한편, 사용자가 등을 중간정도 또는 약하게 긁고자 할 경우에는, 헤드부(8)와 마찰부(4)에 삽입되어 있는 원형삽입축(10)을 외측으로 이탈시킨 상태에서 다시 원하는 접촉면을 헤드부(8) 상면에 노출시켜 사용할 수 있다.On the other hand, when the user wants to scratch the back to a medium or light degree, the circular insertion shaft 10 inserted into the head portion 8 and the friction portion 4 is moved outward and the desired contact surface is again placed on the head portion. (8) It can be used by exposing it to the upper surface.

이때, 원형삽입축(10)을 마찰부(4)의 관통공(3)에서 이탈시키면 원형삽입축(10)의 돌기(9)가 걸림홈(7)에서 이탈되므로 마찰부(4)를 회전시켜 원하는 접촉면이 표면에 노출되도록 위치시킨다.At this time, when the circular insertion shaft 10 is separated from the through hole 3 of the friction portion 4, the protrusion 9 of the circular insertion shaft 10 is separated from the locking groove 7, thereby rotating the friction portion 4. and position it so that the desired contact surface is exposed to the surface.

이와 같이 마찰부(4)의 접촉면(2)을 원하는 마찰계수를 가진 쪽으로 변경시킨 상태에서 다시 원형삽입축(10)을 마찰부(4)의 관통공(3)에 밀어 넣고 원형삽입축(10)의 돌기(9)를 걸림홈(7)에 고정시키면 마찰부(4)가 유동하지 않고 고정된 상태에서 등긁개를 사용할 수 있는 것으로, 상기 걸림홈(7)은 다수개 형성되어 있어 원하는 마찰계수를 가진 접촉면(2)의 위치에서 돌기(9)를 걸림홈(7)에 삽입시켜 고정시킬 수 있는 것이다.In this way, in a state where the contact surface 2 of the friction part 4 is changed to the side with the desired friction coefficient, the circular insertion shaft 10 is again pushed into the through hole 3 of the friction part 4 and the circular insertion shaft 10 )'s protrusion (9) is fixed to the locking groove (7), so that the back scraper can be used while the friction part (4) is fixed and does not move. Multiple locking grooves (7) are formed to provide the desired friction. It can be fixed by inserting the protrusion (9) into the locking groove (7) at the position of the contact surface (2) with the coefficient.

여기서, 상기 마찰부(4)의 접촉면(3)은 예를 들어, 산업용 다이아몬드로 형성할 수 있는 것으로, 접촉면(2)에 산업용 다이아몬드 양의 점유 정도를 달리하여 마찰계수를 강하게 하거나 중간정도로 하거나 또는 약하게 설정할 수 있다. Here, the contact surface 3 of the friction part 4 can be formed of, for example, industrial diamond, and the friction coefficient can be made strong or medium by varying the degree of occupancy of the amount of industrial diamond on the contact surface 2. It can be set to weak.

상술한 바와 같은 본 발명은 상기 실시예에 국한되는 것은 아니며, 본 발명이 속하는 기술분야에서 다양한 실시예를 통하여 유용하게 적용할 수 있음은 물론이다.The present invention as described above is not limited to the above embodiments, and of course can be usefully applied through various embodiments in the technical field to which the present invention pertains.
