선풍기의 두부에 결합도는 넥크(10)와 좌대에 입설된 지주의 상단부에 형성된 넥크홀더(30), 그리고 넥크(10)를 넥크홀더(30)에 체결할때 이들 사이에 개재시키는 래치트(20)로 크게 분류하여 볼수 있다. 이를 좀더 상세히 설명하면, 넥크(10)의 하측 원호면에 래치트 스프링(12)과 볼베어링(16)(16')이 삽입되는 베어링공(15)이 천공되고 중심부에 축공(13)이 관통되며, 축공(13)의 외주면에는 환상의 스프링홈(14)이 형성됨과 동시에 그 스프링홈(14)의 하측 즉, 베어링공(15)의 상측에는 넥크스프링(17)의 일측단(17a)이 괘지되는 요삽홈(18)이 요설된다.The coupling degree of the head of the fan is a neck holder 30 formed at the upper end of the neck 10 and the support post placed on the seat, and a ratchet interposed therebetween when the neck 10 is fastened to the neck holder 30. 20) can be broadly classified. To explain this in more detail, the bearing hole 15 into which the ratchet spring 12 and the ball bearings 16 and 16 'are inserted is drilled in the lower circular arc surface of the neck 10 and the shaft hole 13 penetrates the center thereof. On the outer circumferential surface of the shaft hole 13, an annular spring groove 14 is formed and at one end 17a of the neck spring 17 is located below the spring groove 14, that is, above the bearing hole 15. Concave insertion groove 18 is provided.
한편, 지지판(22)(22')이 ㄷ자상으로 절곡되어 나란하게 대향 입설된 래치트(20)의 선단부는 원호상을 이루고 그 일측 지지판(22)의 상단 원호면에는 상기 넥크스프링(17)의 타측단(17b)이 괘지되는 괘지홈(24)이 요설됨과 아울러 양지지판(22)(22')의 중심부에는 축공(23)이 관통되고, 그 하부에는 일정간격을 두고 수개의 걸림공(26)이 양지지판(22)(22')을 관통하여 천공되는 한편, 좌대에 입설된 지주의 상단부에 형성된 넥크홀더(30)에는 상기 넥크(10)가 래치트(20)와 결합되어 수용되도록 래치트홈(34)을 갖는 한쌍의 지지간(32)(32')이 서로 대항되게 입설되고, 그 중심부에는 양지지간(32)(32')을관통하는 축공(33)이 형성되어 구성된다.On the other hand, the support plates 22 and 22 'are bent in a c-shape and the front end portions of the ratchets 20 side-by-side facing each other form an arc shape, and the neck spring 17 is formed on the upper arc surface of one side of the support plate 22. In the center of both support plates 22 and 22 ', the recessed groove 24 through which the other end 17b of the main body is recessed is provided. 26 is perforated through both support plates 22 and 22 ', and the neck 10 is coupled to the ratchet 20 so as to be accommodated in the neck holder 30 formed at the upper end of the strut placed on the base. A pair of support bars 32 and 32 'having ratchet grooves 34 are placed opposite each other, and a shaft hole 33 is formed in the central portion thereof to penetrate both support bars 32 and 32'. .
이와 같은 구조를 가지는 종래 선풍기의 상하각도 조절장치의 결합과정과 작용상태를 보면, 먼저 넥크(10)의 스프링홈(14)에 양단(17a)(17b)이 직각을 이루고 있는 네크스프링(17)의일측단(17a)을 상기 스프링홈(14)의 하측에 형성된 요삽홈(18)에 삽입하여 괘지시킨 다음 베어링공(15)에는 래치트 스프링(12)을 개재시켜 그 양측에 볼베어링(16)(16')을 삽입하여 래치트(20)에 결합시킨다.Looking at the coupling process and the operating state of the vertical angle control device of the conventional fan having such a structure, first, the neck spring 17 is formed at both ends (17a) (17b) of the spring groove 14 of the neck 10 at right angles. Insert one side end (17a) into the concave insertion groove (18) formed on the lower side of the spring groove (14) and hung it, and then the bearing hole (15) is interposed with a ratchet spring (12) and a ball bearing (16) on both sides thereof ( 16 ') is inserted into the ratchet 20.
이때 넥크스프링(17)의 타측단(17b)은 래치트(20)의 일측지지판(22)상단 원호면에 요설된 괘지홈(24)에 괘지시키고 볼베어링(16)(16')은 임의의 걸림공(26)에 일치시켜 넥크(10)와 래치트(20)를 일단 결합하고 이들의 결합체를 넥크홀더(30)의 양 지지간(32)(32')사이의 래치트홈(34)에 안착시켜 넥크(10), 래치트(20) 그리고 넥크홀더(30)에 각각 천공된 축공(13)(23)(33)을 일치시킨 상태에서 고정용 보올트(36)와 너트(38)로 결합시킨다.At this time, the other end (17b) of the neck spring (17) is hung on the locking groove 24, which is formed on the upper arc surface of the upper side of the support plate 22 of the ratchet 20, and the ball bearings (16) and (16 ') are caught at random. The neck 10 and the ratchet 20 are first coupled in accordance with the ball 26, and the combination thereof is connected to the ratchet groove 34 between both support sections 32 and 32 'of the neck holder 30. With the bolts 36 and the nuts 38 fixed to the neck 10, the ratchet 20, and the neck holders 13, 23, 33, which are drilled into the neck holders 13, 23, 33, respectively, Combine.
이상과 같이된 상기 구조는 선풍기의 두부에 전방이나 후방으로 외력을 가하여 각도를 주게되면 넥크스프링(17)의 탄력을 받아 두부가 지지되면서 래치트(20)의 하부에 천공된 임의의 걸림공(26)에 볼베어링(16)(16')이 걸리도록 하여 두부의 상하각도를 조절하였다.The structure as described above is given any angle by applying an external force to the head of the fan to the front or the rear to receive the elasticity of the neck spring 17 while the head is supported by any locking hole (hole) 26) the ball bearings 16 and 16 'were hung to adjust the vertical angle of the head.
따라서, 이와 같은 종래의 구조는 걸림공이 형성된 위치에서만 넥크가 정지하게 되므로 그 조절각이 걸림공에 의하여 한정되고 상하로 각도조절을 하기 위하여 두부에 외력을 가할시 베어링이 걸림공을 통과하면서, 발생되는 소음등으로 인하여 사용자로 하여금 불괘감과 짜증을 유발하게 됨은 물론 그 구조가 복잡하여 제작 및 조립공정이 번거롭고 생산성 저하와 원가상승의 요인이 되는등 여러가지 문제점과 결함을 안고 있었다.Therefore, the conventional structure is such that the neck is stopped only in the position where the engaging hole is formed, the control angle is limited by the engaging hole and when the bearing is passed through the engaging hole when external force is applied to the head for angle adjustment up and down, Due to the noise, such as the user to cause malaise and irritation, as well as its structure is complicated, the manufacturing and assembly process is cumbersome, and the productivity and cost increase factors have had various problems and defects.
본 고안은 상기와 같은 종래의 문제점 및 결함을 해소하고자 넥크의 원호면 외측벽에 압착돌기르 일체로 돌설하고 래치트의 양지지판에는 이와 접하는 탄성편을 서로 대향되게 전단 절곡하여 내향돌설하여 이들의 탄성에 의한 마찰력을 이용 조절범위내의 어느 부위에서나 조절각도를 제한받지 않고 두부를 정지시킬 수 있도록 안출한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above problems and defects, the present invention integrally squeezes the compression protrusions on the outer wall of the circular arc surface of the neck. By using the frictional force by using any position in the control range without restraining the head to be restrained without restricting the angle, it will be described in detail by the accompanying drawings as follows.
제3도는 본 고안의 구성을 보이기 위한 분해사시도이고, 제4도는 본 고안의 결합상태를 보인 사시도로서, 이에 도시한 바와 같이 넥크(10)하측에 형성된 원호면 양측벽에 상측을 향하여 일측단이 돌출되는압착돌기(19)(19')를 각각 만곡형성하고 넥크(10)의 외주면에 결합되는 래치트(20)의 양지지판(22)(22')에는 상기 압착돌기(19)(19')와 연접하는 일정부위를 ㄷ자상으로 전단 절곡하여 탄성편(28)(28')을 각각 내향 돌설하여서 된 것이다.Figure 3 is an exploded perspective view for showing the configuration of the present invention, Figure 4 is a perspective view showing a coupling state of the present invention, as shown therein one side end toward the upper side of the circular arc formed on both sides of the neck 10 Each of the compression protrusions 19 and 19 'is formed on both support plates 22 and 22' of the ratchet 20, each of which protrudes the pressing protrusions 19 and 19 'and is coupled to the outer circumferential surface of the neck 10. ) By shear bending a certain portion in contact with the c-shape and inclining the elastic pieces 28 (28 ') inward.
이와 같이 된 본 고안의 장치를 결합시키는 넥크(10)를 래치트(20)에 결합하고 이들을 다시 넥크홀더(30)의 래치트홈(34)에 안착시켜 축공(13)(23)(33)을 일치시킨 다음 고정용 보올트(36)와 너트(38)로 체결하여 간단히 결합을 시키게 된다.The neck 10 for coupling the device of the present invention as described above is coupled to the ratchet 20 and seated in the ratchet groove 34 of the neck holder 30 again to form a shaft hole 13, 23, 33. Then, the fixing bolt 36 and the nut 38 are fastened to each other to be simply engaged.
이상과 같은 본 고안의 상하각도 조절장치는 선풍기의 두부에 외력을 가하여 전방으로 숙이게 되면 넥크(10)의 일측 압착돌기(19)에 접하는 래치트(20)의 탄성편(28)이 그 탄성으로 인하여 압착되게 되고, 이에따라 마찰력이 상승하게 되므로 두부의 무게를 충분히 지지할 수 있게되며, 이와 반대로 후방으로 외력을 가할때는 타측 압착돌기(19')에 접하는 래치트(20)의 탄성편(28')이 압착되어 상기와 같은 작용으로 두부를 지지하게 된다.When the upper and lower angle adjusting device of the present invention is leaned forward by applying an external force to the head of the fan, the elastic piece 28 of the ratchet 20 in contact with the one side pressing projection 19 of the neck 10 is elastic. Due to the pressing force, the friction force is increased accordingly, so that the weight of the head can be sufficiently supported. On the contrary, when the external force is applied to the rear side, the elastic piece 28 'of the ratchet 20 contacting the other pressing protrusion 19' is applied. ) Is pressed to support the head by the above action.
따라서, 본 고안의 선풍기 상하각도 조절장치는 넥크의 돌기와 래치트의 탄성편이 압착되기 때문에 그 조절이 가능한 범위각 내에서는 어느 지점에서나 두부를 정지 시킬 수 있게 되며, 종래의 각도조절시 발생되던 불괘한 소음을 방지하게 된다. 또한 별도의 스프링이나 볼베어링을 사용하지 않게 되므로 그 구조가 간단해지고 제작 및 조립공정이 현저하게 단축되어 생산성 향상은 물론 원가절감에 크게 기여할 수 있는등 여러가지 장점을 제공해준다.Therefore, the fan vertical angle adjustment device of the present invention is able to stop the head at any point within the range angle that can be adjusted because the projection of the neck and the elastic piece of the ratt is compressed, the unfairness caused during the conventional angle adjustment It will prevent noise. In addition, since it does not use a separate spring or ball bearing, its structure is simplified, and the manufacturing and assembly process is significantly shortened, thus providing various advantages such as improving productivity and greatly reducing cost.
