록킹부(120)를 암 레스트(300)의 측단(313)보다 내측으로 위치시키기 위해, 암 레스트(300)의 저부(320)는 노브 수용부(321)를 갖는다. 노브 수용부(321)는 콘솔의 상부(210)의 내측단보다 내측에 위치하고 콘솔의 하측을 향해 돌출한다. 노브 수용부(321)는 록킹부(120)를 암 레스트의 저부(320)에 수용할 수 있는 수용 공간를 한정한다.In order to position the locking portion 120 inward than the side end 313 of the armrest 300, the bottom portion 320 of the armrest 300 has a knob receiving portion 321. The knob accommodating portion 321 is located inside the upper end of the upper portion 210 of the console and protrudes toward the lower side of the console. The knob accommodating portion 321 defines an accommodating space that can accommodate the locking portion 120 in the bottom portion 320 of the arm rest.
도 3 내지 도 5를 참조하면, 일 실시예에 따른 록킹부(120)는 록킹 노브(130)와 노브 스프링(140)을 포함한다. 록킹 노브(130)는 걸림 돌기(110)와 걸림결합하도록 구성된다. 노브 스프링(140)이 록킹 노브(130)를 콘솔에 위치한 걸림 돌기(110)를 향해 항상 가압한다. 즉, 록킹 노브(130)는 노브 스프링(140)에 의해 암 레스트의 측단을 향해 항상 밀린다. 노브 스프링(140)에 의해 항상 밀리는 록킹 노브(130)가 걸림 돌기와 해제 가능하게 걸림결합된다. 이와 같이, 록킹 노브(130)와 노브 스프링(140)으로 구성되는 록킹부(120)는 자동차의 탑승자가 록킹부(120)를 조작함이 없이 셀프 록킹을 실행할 수 있다.3 to 5, the locking unit 120 according to an embodiment includes a locking knob 130 and a knob spring 140. The locking knob 130 is configured to engage with the locking protrusion 110. The knob spring 140 always presses the locking knob 130 toward the locking projection 110 located on the console. That is, the locking knob 130 is always pushed toward the side end of the arm rest by the knob spring 140. The locking knob 130, which is always pushed by the knob spring 140, is engaged with the locking projection and release. As described above, the locking unit 120 composed of the locking knob 130 and the knob spring 140 may perform self-locking without the occupant of the vehicle operating the locking unit 120.
일 실시예에 있어서, 록킹 노브(130)는 결합부(131)와 걸림부(132)를 가지며, 걸림부(132)는 결합부(131)와 일체로 형성된다. 결합부(131)가 록킹 노브의 일측부를 형성하고, 걸림부(132)가 록킹 노브의 타측부를 형성한다. 노브 스프링(140)은 록킹 노브의 걸림부(132)와 접촉한다. 록킹 노브(130)는 결합부(131)에서 암 레스트의 저부(320)에 회전 가능하게 결합된다. 록킹 노브(130)의 걸림부(132)가 노브 스프링(140)의 가압력에 의해 콘솔의 걸림 돌기(110)와 걸림결합한다.In one embodiment, the locking knob 130 has an engaging portion 131 and an engaging portion 132, and the engaging portion 132 is integrally formed with the engaging portion 131. The engaging portion 131 forms one side of the locking knob, and the locking portion 132 forms the other side of the locking knob. The knob spring 140 contacts the locking portion 132 of the locking knob. The locking knob 130 is rotatably coupled to the bottom portion 320 of the arm rest at the engaging portion 131. The locking portion 130 of the locking knob 130 is engaged with the locking projection 110 of the console by the pressing force of the knob spring 140.
결합부(131)는 힌지축(133)을 갖는다. 결합부(131)와 힌지축(133)은 일체로 형성된다. 즉, 힌지축(133), 결합부(131) 및 걸림부(132)가 일체로 형성될 수 있다. 결합부(131)는 힌지축(133)에 의해 암 레스트의 저부(320)에 힌지축(133)을 중심으로 회전가능하게 결합된다. 걸림부(132)는 결합부(131)로부터 절곡되어 있다. 걸림부(132)는 직각으로 결합부(131)로부터 절곡될 수 있다. 결합부(131)가 회전가능하므로, 걸림부(132)는 암 레스트의 측단(313)을 향해 이동되거나 암 레스트의 측단(313)으로부터 멀어지게 이동된다.The coupling portion 131 has a hinge shaft 133. The coupling portion 131 and the hinge shaft 133 are integrally formed. That is, the hinge shaft 133, the engaging portion 131 and the locking portion 132 may be integrally formed. The coupling part 131 is rotatably coupled to the bottom part 320 of the arm rest by the hinge axis 133 around the hinge axis 133. The engaging portion 132 is bent from the engaging portion 131. The engaging portion 132 may be bent from the engaging portion 131 at a right angle. Since the engaging portion 131 is rotatable, the locking portion 132 is moved toward the side end 313 of the arm rest or away from the side end 313 of the arm rest.
노브 스프링(140)은, 록킹 노브(130)의 걸림부(132)가 걸림 돌기(110)에 밀착되도록 걸림부(132)를 걸림 돌기(110)를 향해 항상 가압한다. 노브 스프링(140)은 압축 코일 스프링을 포함할 수 있지만, 이에 한정되지는 않는다. 노브 스프링(140)의 가압력은 항상 암 레스트(300)의 측단(313)을 향해 작용한다. 노브 스프링(140)의 가압력이 작용하고 암 레스트가 콘솔의 상부에 록킹된 상태에서, 걸림부(132)와 걸림 돌기(110)는 록킹 상태로 유지된다. 외력이 노브 스프링(140)의 가압력의 방향에 반대되는 방향으로 걸림부(132)에 가해질 수 있다. 예컨대, 암 레스트를 콘솔의 상부로부터 들어올리거나 암 레스트를 콘솔의 상부를 향해 누르는 경우, 걸림 돌기(110)로부터 걸림부(132)에 상기 외력이 가해질 수 있다. 결합부(131)가 회전하므로, 상기 외력은 록킹 노브(130)를 노브 스프링(140)의 가압력에 저항하면서 암 레스트의 내측을 향해(예컨대, 도 3에서 내측 방향(LI)으로) 회전시킨다. 이에 따라, 걸림부(132)와 걸림 돌기(110)의 걸림결합이 해제될 수 있다.The knob spring 140 always presses the locking portion 132 toward the locking projection 110 so that the locking portion 130 of the locking knob 130 is in close contact with the locking projection 110. The knob spring 140 may include, but is not limited to, a compression coil spring. The pressing force of the knob spring 140 always acts toward the side end 313 of the arm rest 300. While the pressing force of the knob spring 140 is applied and the arm rest is locked to the upper portion of the console, the locking portion 132 and the locking protrusion 110 are maintained in the locked state. An external force may be applied to the locking portion 132 in a direction opposite to the direction of the pressing force of the knob spring 140. For example, when lifting the arm rest from the top of the console or pressing the arm rest toward the top of the console, the external force may be applied to the locking portion 132 from the locking projection 110. Since the engaging portion 131 rotates, the external force rotates the locking knob 130 toward the inner side of the arm rest (eg, in the inner direction LI in FIG. 3) while resisting the pressing force of the knob spring 140. Accordingly, the engagement of the engaging portion 132 and the engaging projection 110 can be released.
도 6 내지 도 8을 참조한다. 노브 스프링(140)은 걸림부(132)와 암 레스트의 저부(320)의 사이에 배치된다. 걸림부(132)는 노브 스프링(140)의 일단부가 삽입되는 삽입홀(134)을 갖는다. 삽입홀(134)이 걸림부(132)의 내측단으로부터 선단을 향해 걸림부(132) 내에 뚫려 있다. 삽입홀(134)의 바닥면에는 핀(135)이 돌출한다. 노브 스프링(140)은, 핀(135)이 그 내부에 삽입되도록, 삽입홀(134)에 삽입된다. 암 레스트는 저부(320)에는, 삽입홀(134)에 일단부가 삽입된 노브 스프링(140)의 타단부가 안착되는 안착홈(141)이 형성되어 있다. 안착홈(141)은 노브 수용부(321)의 외측 표면에 오목하게 형성되어 있다.See FIGS. 6 to 8. The knob spring 140 is disposed between the locking portion 132 and the bottom portion 320 of the arm rest. The locking portion 132 has an insertion hole 134 into which one end of the knob spring 140 is inserted. The insertion hole 134 is drilled in the locking portion 132 from the inner end of the locking portion 132 toward the tip. The pin 135 protrudes from the bottom surface of the insertion hole 134. The knob spring 140 is inserted into the insertion hole 134 so that the pin 135 is inserted therein. The arm rest has a seating groove 141 in which the other end of the knob spring 140 is inserted into the insertion hole 134 in the bottom part 320. The seating groove 141 is concavely formed on the outer surface of the knob receiving portion 321.
걸림부(132)는 암 레스트의 상기 측단을 향하는 선단부(136)를 갖는다. 선단부(136)가 걸림 돌기(110)와 접촉되어, 걸림 돌기(110)와 걸림부(132)를 걸림 결합시킨다. 이때, 노브 스프링(140)의 가압력에 의해 암 레스트(300)를 록킹하는 록킹력이 발생된다. 또한, 선단부(136)는 걸림 돌기(110)와 접촉되어, 걸림 돌기(110)와 걸림부(132)를 걸림 결합으로부터 해제시킴으로써, 노브 스프링(140)의 가압력 하에서 암 레스트(300)의 록킹력이 해제된다.The locking portion 132 has a tip portion 136 facing the side end of the arm rest. The front end portion 136 is in contact with the engaging projection 110, engaging the engaging projection 110 and the engaging portion 132. At this time, a locking force for locking the arm rest 300 is generated by the pressing force of the knob spring 140. In addition, the tip portion 136 is in contact with the engaging projection 110, by releasing the engaging projection 110 and the engaging portion 132 from the engaging engagement, the locking force of the arm rest 300 under the pressing force of the knob spring 140 Is released.
일 실시예에 있어서, 걸림부(132)의 선단부(136)는 걸림면(137)과 누름면(138)과 걸림면(137)과 누름면(138)의 사이에 위치하는 천이면(139)을 포함한다. 걸림면(137)은 선단부(136)의 상부를 형성하며, 걸림 돌기(110)의 절곡 형상에 대응하도록 대략 L자 형상을 갖는다. 즉, 걸림면(137)은 암 레스트의 상기 측단에 대해 오목한 형상을 갖는다. 누름면(138)은 선단부(136)의 하부를 형성하며, 천이면(139)을 통해 걸림면(137)에 연결된다. 누름면(138)은 암 레스트의 상기 측단을 향해 볼록하게 라운드된 표면으로 형성되어 있다.In one embodiment, the front end portion 136 of the locking portion 132 is a locking surface 139 located between the locking surface 137 and the pressing surface 138 and the locking surface 137 and the pressing surface 138 It includes. The engaging surface 137 forms an upper portion of the distal end portion 136 and has an approximately L-shape to correspond to the bending shape of the engaging projection 110. That is, the engaging surface 137 has a concave shape with respect to the side end of the arm rest. The pressing surface 138 forms a lower portion of the tip portion 136 and is connected to the locking surface 137 through the transition surface 139. The pressing surface 138 is formed with a convexly rounded surface toward the side end of the arm rest.
암 레스트가 콘솔의 상부에 록킹되어 있을 때, 걸림면(137)은 암 레스트의 측단을 향하는 방향에서 걸림 돌기(110)와 접촉하여, 노브 스프링(140)의 가압력 하에서 록킹 작용을 발생시킨다. 누름면(138)은 걸림 돌기(110)의 상단 엣지와 슬라이드 접촉할 수 있다. 암 레스트를 콘솔의 상부를 향해 회전시킬 때, 걸림 돌기(110)는 그 상단 엣지에서 누름면(138)과 슬라이드 접촉한다. 그러면, 암 레스트를 하방으로 누르는 힘에 대한 반력이 걸림 돌기(110)로부터 누름면(138)에 가해지고, 이러한 반력이 록킹 노브(130)를 암 레스트의 내측으로(예컨대, 도 3에서 내측 방향(LI)으로) 누름 스프링(140)의 가압력에 반하여 회전시킨다. 즉, 암 레스트를 콘솔의 상부로 회전 시킬 때, 걸림 돌기(110)와 누름면(138) 간의 슬라이드 접촉이 록킹 노브(130)를 암 레스트의 내측으로 회전시킨다.When the arm rest is locked to the upper portion of the console, the engaging surface 137 contacts the engaging projection 110 in the direction toward the side end of the arm rest, thereby generating a locking action under the pressing force of the knob spring 140. The pressing surface 138 may slide contact with the upper edge of the locking protrusion 110. When the arm rest is rotated toward the top of the console, the locking projection 110 slides into contact with the pressing surface 138 at its upper edge. Then, the reaction force against the force pressing the arm rest downward is applied to the pressing surface 138 from the locking projection 110, and this reaction force moves the locking knob 130 inward of the arm rest (e.g., inward direction in FIG. 3). (To LI)) rotates against the pressing force of the pressing spring 140. That is, when the arm rest is rotated to the top of the console, the slide contact between the locking projection 110 and the pressing surface 138 rotates the locking knob 130 to the inside of the arm rest.
도 7 및 도 8을 참조하면, 암 레스트의 저부(320)의 노브 수용부(321)는 걸림부(132)가 통과하는 관통공(322)을 갖는다. 결합부(131)가 회전가능하므로, 걸림부(132)는 관통공(322)의 외측으로 또한 내측으로 소정 범위 내에서 이동될 수 있다. 즉, 걸림부(132)는 암 레스트의 상기 측단을 향해 이동되거나 상기 측단으로부터 멀어지게 이동된다.7 and 8, the knob receiving portion 321 of the bottom portion 320 of the arm rest has a through hole 322 through which the locking portion 132 passes. Since the engaging portion 131 is rotatable, the locking portion 132 may be moved outward and inward of the through hole 322 within a predetermined range. That is, the locking portion 132 is moved toward the side end of the arm rest or is moved away from the side end.
또한, 일 실시예의 암 레스트 록킹 장치는, 걸림 돌기(110)로부터 분리된 걸림부(132)와 접촉하여 록킹 노브(130)가 암 레스트의 외측으로(즉, 암 레스트의 상기 측단을 향해) 소정 한계 이상 회전되는 것을 방지하는 스토퍼부(150)를 포함한다. 스토퍼부(150)는 암 레스트의 저부(320)에 형성될 수 있다. 스토퍼부(150)는 관통공(322)의 상측에 위치하는 노브 수용부(321)의 부분을 포함할 수 있다. 암 레스트가 콘솔의 상부로부터 언록킹된 상태에서 록킹 노브(130)가 암 레스트의 측단(313)을 향해 노브 스프링(140)에 의해 밀릴 때, 스토퍼부(150)는 걸림부(132)의 상면과 접촉하여 걸림부(132)가 암 레스트의 측단(313)을 넘어 회전하는 것을 방지할 수 있다.In addition, in one embodiment, the arm rest locking device contacts the locking part 132 separated from the locking protrusion 110 so that the locking knob 130 is outside the arm rest (that is, toward the side end of the arm rest). It includes a stopper portion 150 that prevents rotation beyond the limit. The stopper part 150 may be formed on the bottom part 320 of the arm rest. The stopper part 150 may include a portion of the knob accommodating part 321 positioned above the through hole 322. When the armrest is unlocked from the top of the console, when the locking knob 130 is pushed by the knob spring 140 toward the side end 313 of the armrest, the stopper portion 150 is the upper surface of the locking portion 132 It is possible to prevent the locking portion 132 from rotating over the side end 313 of the arm rest in contact with the.
