본 발명은 모바일단말기용 핑거그립에 관한 것으로, 보다 자세히는 사용자의 손가락을 끼워 사용하지 않을 때는 모바일단말기에 밀착된 잠금상태가 견고하게 유지될 수 있는 모바일단말기용 핑거그립에 관한 것이다.The present invention relates to a finger grip for a mobile terminal, and more particularly, to a finger grip for a mobile terminal capable of securely maintaining a locked state in close contact with a mobile terminal when not in use with a user's finger interposed therebetween.
현재 스마트폰 등 모바일단말기의 사용이 증가하면서 장시간 동안 스마트폰을 손에 쥐고 있으면 사용자에게 일정한 체력적 부담을 가져다 주게 된다.Currently, as the use of mobile terminals such as smartphones increases, holding a smartphone in hand for a long time brings a certain amount of physical burden to the user.
특히, 최근에 판매되는 스마트폰들은 사용자의 요구에 맞춰 디스플레이 화면의 크기는 갈수록 커지는 추세이며, 이에 상대적으로 손이 작은 사용자들은 사용하는데에 있어 각별한 주의가 필요하게 되었다.In particular, in recent smart phones, the size of the display screen tends to increase according to the user's needs, and thus, users with relatively small hands need special attention in using it.
또한 특별한 장소, 예를 들면, 운전 중에 스마트폰 네비게이션을 사용시 두 손이 자유롭지 못하기 때문에 사용자에게 일정한 안전 위험을 가져다 준다. 뿐만아니라 스마트폰 운영체제와 터치스크린의 기술이 갈수록 발전함에 따라 스크린이 커짐으로 인해 한 손 조작에도 일정한 어려움이 존재하게 되어 손이 작은 여성 및 잠들기 전에 스마트폰을 사용하는 사람들에게 있어서 한 손 조작이 극히 어려워 스마트폰이 쉽게 떨어지는 경우가 있다. In addition, it brings a certain safety risk to the user because both hands are not free when using the smartphone navigation while driving in a special place, for example. In addition, as the technology of the smartphone operating system and touch screen continues to develop, certain difficulties exist even in one-handed operation due to the enlarged screen. It is difficult and there are cases where the smartphone falls easily.
이러한 문제를 해결하기 위해 필요에 따라 사용자의 손가락을 끼워 사용하는 핑거그립이 개발된 바 있다.In order to solve this problem, a finger grip has been developed that uses the user's finger as needed.
도 1은 종래 기술에 의한 핑거그립(10)를 예시하는 도면이다. 도시된 바와 같이 종래 핑거그립(10)은 모바일단말기에 부착되는 베이스(11)와, 베이스(11)에 이동가능하게 결합되는 신축시트(13)를 포함한다. 신축시트(13)는 일단은 베이스(11)에 고정되고, 타단은 보스(15)에 의해 베이스(11)에 형성된 가이드홈(11a)을 따라 직선이동가능하게 구비된다. 1 is a diagram illustrating a finger grip 10 according to the prior art. As shown, the conventional finger grip 10 includes a base 11 attached to a mobile terminal, and an elastic sheet 13 movably coupled to the base 11 . One end of the elastic sheet 13 is fixed to the base 11 , and the other end is provided to be movable in a straight line along the guide groove 11a formed in the base 11 by the boss 15 .
이에 의해 신축시트(13)는 가이드홈(11a)을 따라 이동하며 베이스(11)에 대해 펼쳐지거나 접혀지게 된다. 도 1의 (a)에 도시된 바와 같이 신축시트(13)가 접혀지면 손가락이 삽입될 수 있는 공간이 베이스(11)와의 사이에 형성되어 사용자가 손가락을 삽입하여 모바일단말기를 용이하게 잡고 사용할 수 있게 된다. As a result, the elastic sheet 13 moves along the guide groove 11a and is unfolded or folded with respect to the base 11 . As shown in (a) of FIG. 1 , when the elastic sheet 13 is folded, a space for inserting a finger is formed between the base 11 and the user, so that the user can easily hold and use the mobile terminal by inserting a finger. there will be
그런데, 종래 핑거그립(10)은 신축시트(13)가 실리카겔로 형성되므로, 장시간 사용할 경우 늘어나게 된다. 이에 따라 도 1의 (b)에 도시된 바와 같이 사용자가 사용을 하지 않는 경우에 신축시트(13)가 베이스(11)에 펼쳐져 베이스(11)에 밀착된 상태를 유지해야함에도 불구하고, 신축시트(13)가 베이스(11)로부터 일정높이(h) 떠있게 되는 문제가 있었다. However, in the conventional finger grip 10, since the elastic sheet 13 is formed of silica gel, it is stretched when used for a long time. Accordingly, although the elastic sheet 13 is spread on the base 11 to maintain a state in close contact with the base 11 when the user does not use it as shown in FIG. 1 (b), the elastic sheet (13) There was a problem in that a certain height (h) floating from the base (11).
이렇게 신축시트(13)가 베이스(11)로부터 일정높이 떠있게 되더라도 신축시트(13)가 펼쳐진 상태를 유지하게 위치를 고정할 잠금수단이 없어 사용시간이 길어질수록 신축시트(13)가 베이스(11)로부터 떠 있는 높이(h)가 점점 더 높아져 미관상으로도 보기 좋지 않은 단점이 있다. Even if the elastic sheet 13 floats at a certain height from the base 11 in this way, there is no locking means to fix the position to maintain the stretched sheet 13 in an unfolded state, so the longer the use time, the longer the elastic sheet 13 is the base 11 ), the height (h) floating from it is getting higher and higher, so there is a disadvantage that it does not look good from an aesthetic point of view.

A shaft guide groove 210 in which the coupling shaft 410 of the fixed rivet 400 is moved is formed on the upper surface of the guide member 200 , and the rivet guide in which the fixing rivet 400 is moved is formed on the lower surface of the guide member 200 . A groove 220 is formed. In addition, at one end of the upper surface of the guide member 200, a coupling groove 230 to which the fixing protrusion 310 of the variable band 300 is coupled is formed to be depressed to a predetermined depth.

축가이드홈(210)은 가변밴드(300)의 슬라이딩핀(320)이 전후로 왕복 이동될 수 있게 안내한다. 이를 위해 축가이드홈(210)의 폭은 결합축(410)과 슬라이딩핀(320)의 결합방식에 따라 결합축(410)의 직경에 대응되거나 슬라이딩핀(320)의 직경에 대응되게 구비된다. 리벳가이드홈(220)의 폭은 고정리벳(400)의 직경과 동일하거나 크게 형성된다. The shaft guide groove 210 guides the sliding pin 320 of the variable band 300 to be reciprocally moved back and forth. For this, the width of the shaft guide groove 210 corresponds to the diameter of the coupling shaft 410 or the diameter of the sliding pin 320 according to the coupling method between the coupling shaft 410 and the sliding pin 320 . The width of the rivet guide groove 220 is formed to be equal to or larger than the diameter of the fixed rivet 400 .

The shaft guide groove 210 includes a maximum folding fixing groove 211 for fixing the coupling shaft 410 so that the variable band 300 is folded to a maximum height for the user to use by inserting the user's finger, and the user does not use the user's finger When not in an unfolding locking groove 213 in which the coupling shaft 410 is positioned so as to spread the variable band 300 in close contact with the guide member 200, and from the maximum folding fixing groove 211 toward the unfolding locking groove 213 A straight guide rail 212 connected in a straight line for a certain length and a curved shape from the end of the straight guide rail 212 to the expansion lock groove 213 are formed so that the coupling shaft 410 of the expansion lock groove 213 is the user's The curved sliding rail 217 that applies resistance to the movement of the coupling shaft 410 to prevent entry into the straight guide rail 212 without external force, and the expansion lock groove 213 are provided inside the expansion lock groove 213 accommodated The coupling shaft 410 includes a locking protrusion 213a for supporting the position of the coupling shaft 410 to be locked so that it cannot be moved without the user's external force application.
도 6의 (a)와 (b)는 각각 가변밴드(300)가 가이드부재(200)에 펼쳐진 상태의 단면구성을 도시한 단면도와 평면구성을 도시한 평면도이고, 도 7의 (a)와 (b)는 각각 가변밴드(300)가 가이드부재(200)에 접혀진 상태의 단면구성을 도시한 단면도와 평면구성을 도시한 평면도이다. 6 (a) and (b) are respectively a cross-sectional view and a plan view showing the cross-sectional configuration of the variable band 300 is spread on the guide member 200, and a plan view showing the plan configuration, Fig. 7 (a) and ( b) is a cross-sectional view showing a cross-sectional configuration in a state in which the variable band 300 is folded in the guide member 200, respectively, and a plan view showing a planar configuration.
축가이드홈(210)은 가이드부재(200)의 일단에서 타단을 향해 일정길이 형성되어 사용자가 가변밴드(300)의 상면을 손으로 가압하면 슬라이딩핀(320)이 펼침잠금홈(213)으로부터 최대접힘고정홈(211)까지 슬라이딩 이동되며 가변밴드(300)의 위치가 이동되게 안내한다. The shaft guide groove 210 is formed with a predetermined length from one end of the guide member 200 toward the other end. It slides to the folding fixing groove 211 and guides the position of the variable band 300 to be moved.
최대접힘고정홈(211)은 직선가이드레일(212)과 "T"자 형태로 형성된다. 최대접힘고정홈(211)은 직선가이드레일(212)을 따라 이동된 결합축(410)이 끼워진 슬라이딩핀(320)이 직선가이드레일(212)의 중심축(도 6의 (b)에서 점선으로 표시)에 대해 좌우로 이동되어 위치가 고정되게 한다. The maximum folding fixing groove 211 is formed in a "T" shape with the straight guide rail 212 . In the maximum folding fixing groove 211, the sliding pin 320 into which the coupling shaft 410 moved along the straight guide rail 212 is fitted is the central axis of the straight guide rail 212 (a dotted line in (b) of FIG. 6). mark) to the left and right to fix the position.
직선가이드레일(212)은 곡선슬라이딩레일(217)로부터 이동된 결합축(410)이 위치되어 가변밴드(300)의 접힘높이가 조절되게 한다. 이 때, 직선가이드레일(212)의 길이방향을 따라 내측벽면에는 복수개의 위치조절홈(215)이 형성된다. In the straight guide rail 212 , the coupling shaft 410 moved from the curved sliding rail 217 is positioned so that the folding height of the variable band 300 is adjusted. At this time, a plurality of positioning grooves 215 are formed on the inner wall surface along the longitudinal direction of the straight guide rail 212 .
복수개의 위치조절홈(215)은 사용자의 손가락 두께에 맞게 가변밴드(300)의 접힘높이가 조절되게 한다. 일례로, 사용자는 도 7의 (a)에 도시된 바와 같이 본인의 손가락 두께에 맞는 가운데 위치조절홈(215)에 결합축(410)이 끼워지게 가변밴드(300)의 이동위치를 조절할 수 있다. The plurality of position adjustment grooves 215 allow the folding height of the variable band 300 to be adjusted according to the thickness of the user's finger. For example, the user can adjust the movement position of the variable band 300 so that the coupling shaft 410 is fitted in the center position adjustment groove 215 suitable for the thickness of the user's finger as shown in (a) of FIG. 7 . .
펼침잠금홈(213)은 도 6의 (a)와 (b)에 도시된 바와 같이 가변밴드(300)가 가이드부재(200)에 펼쳐진 위치가 고정되게 결합축(410)이 수용된다. 펼침잠금홈(213)은 직선가이드레일(212)과 동축상에 위치하게 형성된다. As shown in (a) and (b) of FIG. 6 , the unfolding locking groove 213 accommodates the coupling shaft 410 so that the position where the variable band 300 is spread on the guide member 200 is fixed. The expansion locking groove 213 is formed to be positioned coaxially with the straight guide rail 212 .
이 때, 펼침잠금홈(213)과 곡선슬라이딩레일(217)의 경계영역에는 곡선슬라이딩레일(217)을 향해 돌출형성된 잠금걸림턱(213a)이 구비된다. 잠금걸림턱(213a)은 펼침잠금홈(213)에 수용된 결합축(410)이 사용자의 외력없이 곡선슬라이딩레일(217) 측으로 스스로 이동되지 못하도록 결합축(410)을 접촉지지한다. At this time, a locking projection 213a protruding toward the curved sliding rail 217 is provided in the boundary region between the unfolding locking groove 213 and the curved sliding rail 217 . The locking protrusion 213a contacts and supports the coupling shaft 410 so that the coupling shaft 410 accommodated in the unfolding locking groove 213 cannot move by itself toward the curved sliding rail 217 without the user's external force.
이렇게 결합축(410)이 잠금걸림턱(213a)에 의해 걸려진 상태로 펼침잠금홈(213)에 수용되면, 사용자가 수평방향으로 힘을 주어 가변밴드(300)를 곡선슬라이딩레일(217) 측으로 가압하지 않는 한 결합축(410)이 펼침잠금홈(213)에 수용된 상태가 유지된다. 따라서, 잠금걸림턱(213a)이 잠금수단으로 기능하여 가변밴드(300)가 가이드부재(200)에 밀착된 상태가 유지될 수 있다. In this way, when the coupling shaft 410 is accommodated in the unfolding locking groove 213 in a state of being caught by the locking protrusion 213a, the user applies a force in the horizontal direction to move the variable band 300 toward the curved sliding rail 217. As long as the pressure is not applied, the coupling shaft 410 is maintained in a state accommodated in the expansion locking groove 213 . Accordingly, the locking protrusion 213a functions as a locking means so that the variable band 300 can be maintained in close contact with the guide member 200 .
곡선슬라이딩레일(217)은 잠금걸림턱(213a)을 경유한 결합축(410)이 스스로 직선가이드레일(212) 측으로 이동되지 못하도록 결합축(410)의 직선이동에 저항을 형성한다. The curved sliding rail 217 forms resistance to the linear movement of the coupling shaft 410 to prevent the coupling shaft 410 passing through the locking protrusion 213a from moving toward the straight guide rail 212 by itself.
즉, 결합축(410)은 펼침잠금홈(213)으로부터 벗어나 직선가이드레일(212)을 향해 직선이동하기 위해 힘이 작용된다. 그러나, 곡선슬라이딩레일(217)은 곡선형태로 형성되므로 직선방향으로 힘이 작용되는 결합축(410)이 곡선슬라이딩레일(217)의 곡선형상을 따라 수평방향으로 이동하기는 어렵다. 이에 펼침잠금홈(213)을 사용자의 외력없이 결합축(410)이 벗어나더라도 곡선슬라이딩레일(217)을 따라 이동되지 못하므로 결국 펼침잠금홈(213) 주변에 결합축(410)이 위치하게 되어 가변밴드(300)가 펼쳐진 상태는 유지될 수 있다. That is, a force is applied to the coupling shaft 410 to move straight away from the expansion locking groove 213 toward the straight guide rail 212 . However, since the curved sliding rail 217 is formed in a curved shape, it is difficult for the coupling shaft 410 to which a force is applied in a straight direction to move in the horizontal direction along the curved shape of the curved sliding rail 217 . Accordingly, even if the coupling shaft 410 deviates from the user's external force, the expansion lock groove 213 cannot be moved along the curved sliding rail 217, so the coupling shaft 410 is located around the expansion lock groove 213. An unfolded state of the variable band 300 may be maintained.
곡선슬라이딩레일(217)은 직선가이드레일(212)의 중심축을 기준으로 펼침잠금홈(213)과 대향되는 방향에 위치된다. 이에 의해 펼침잠금홈(213)에 수용된 결합축(410)은 곡선슬라이딩레일(217)을 경유해야만 직선가이드레일(212)로 진입하여 가변밴드(300)가 접혀질 수 있다. The curved sliding rail 217 is positioned in a direction opposite to the expansion locking groove 213 with respect to the central axis of the straight guide rail 212 . Accordingly, the coupling shaft 410 accommodated in the unfolding locking groove 213 enters the straight guide rail 212 only through the curved sliding rail 217 so that the variable band 300 can be folded.
곡선슬라이딩레일(217)은 직선가이드레일(212)로부터 멀어지는 방향으로 곡률이 형성된 상부슬라이딩레일(217a)과, 상부슬라이딩레일(217a)로부터 펼침잠금홈(213)을 연결하며 직선가이드레일(212)과 가까워지는 방향으로 곡률이 형성된 하부슬라이딩레일(217b)을 포함한다. The curved sliding rail 217 connects the upper sliding rail 217a, the curvature of which is formed in a direction away from the straight guide rail 212, and the expansion lock groove 213 from the upper sliding rail 217a, and connects the straight guide rail 212. and a lower sliding rail (217b) having a curvature formed in the approaching direction.
여기서, 하부슬라이딩레일(217b)의 폭(d1)은 직선가이드레일(212)의 폭(d) 보다 크게 형성된다. 그리고, 직선가이드레일(212)의 중심축을 기준으로 펼침잠금홈(213)까지의 너비(ℓ1) 보다 곡선슬라이딩레일(217)의 최대너비(ℓ2)가 크게 형성된다. Here, the width d1 of the lower sliding rail 217b is formed to be larger than the width d of the straight guide rail 212 . In addition, the maximum width ℓ2 of the curved sliding rail 217 is greater than the width ℓ1 of the straight guide rail 212 to the expansion locking groove 213 based on the central axis.
이는 사용자의 외력이 작용하지 않았음에도 불구하고 펼침잠금홈(213)으로부터 이탈한 결합축(410)이 하부슬라이딩레일(217b)로 진입하게 될 때, 수평방향 이동거리(ℓ2)가 길어 더 이상 외력없이 상부슬라이딩레일(217a) 측으로 이동되지 못하게 하기 위함이다. This is when the coupling shaft 410 separated from the unfolding lock groove 213 enters the lower sliding rail 217b despite the user's external force not acting, the horizontal movement distance ℓ2 is long and no longer external force This is to prevent movement to the upper sliding rail (217a) side without it.
또한, 상부슬라이딩레일(217a)의 길이(ℓ3)가 하부슬라이딩레일(217b)의 길이(ℓ4) 보다 길게 형성된다. 최대너비(ℓ2)가 동일하나 길이가 상이하므로 하부슬라이딩레일(217b)의 곡률이 상부슬라이딩레일(217a)의 곡률보다 크게 형성된다. 이에 따라 외력없이 결합축(410)이 하부슬라이딩레일(217b)을 경유하여 상부슬라이딩레일(217a)로 진입하기 어려워지므로 가변밴드(300)는 외력이 작용되지 않는 한 펼침상태가 안정적으로 유지될 수 있다. In addition, the length (ℓ3) of the upper sliding rail (217a) is formed longer than the length (ℓ4) of the lower sliding rail (217b). Since the maximum width ℓ2 is the same but the length is different, the curvature of the lower sliding rail 217b is greater than the curvature of the upper sliding rail 217a. Accordingly, since it becomes difficult for the coupling shaft 410 to enter the upper sliding rail 217a via the lower sliding rail 217b without an external force, the variable band 300 can be stably maintained in an unfolded state unless an external force is applied. there is.
리벳가이드홈(220)은 결합축(410)이 슬라이딩핀(320)에 결합된 상태로 축가이드홈(210)을 따라 이동될 때 고정리벳(400)이 이동되게 안내한다. 리벳가이드홈(220)에는 곡선슬라이딩레일(217)에 대응되는 영역에 곡률홈(221)이 형성된다. 곡률홈(221)은 결합축(410)이 곡선슬라이딩레일(217)을 따라 이동될 때 고정리벳(400)도 동일한 궤적으로 이동될 수 있게 한다. The rivet guide groove 220 guides the fixed rivet 400 to move when the coupling shaft 410 is moved along the shaft guide groove 210 in a state coupled to the sliding pin 320 . A curvature groove 221 is formed in a region corresponding to the curved sliding rail 217 in the rivet guide groove 220 . The curvature groove 221 enables the fixing rivet 400 to move along the same trajectory when the coupling shaft 410 is moved along the curved sliding rail 217 .
