  A guide 23 is formed on the right part of the base 2, and a guide 26 is formed on the left part of the base 2. The guides 23 and 26 are holes penetrating from the back surface of the base 2 to the front surface. The guides 23 and 26 may be grooves recessed in the back surface of the base 2, but even in that case, the shape viewed from the front is the same as in the case of FIGS.

  The guide 23 includes a first guide portion 24 formed in a straight line in the vertical direction, a first hook portion 25 that is connected to the upper end of the first guide portion 24 and bent to the right from the upper end of the first guide portion 24, Consists of. The guide 26 includes a second guide portion 27 that is linearly formed in the vertical direction, and a second hooking portion 28 that is bent leftward from the lower end of the second guide portion 27. The hook portions 25 and 28 are curved in a bow shape. The lengths of the guide portions 24 and 27 are different, and the overall lengths of the guides 23 and 26 are different as a whole. In addition, the full length of the guides 23 and 26 may be equal.

  The slider 3 is formed in a thin plate shape. Carriages 31 and 32 are provided on the left and right sides of the slider 3, and slits 33 and 34 that are long in the vertical direction are formed in the carriages 31 and 32, respectively. The guide rail 21 is inserted into the slit 33, and the guide rail 22 is inserted into the slit 34. The carriage 31 can slide along the guide rail 21, and the carriage 32 can slide along the guide rail 22, so that the slider 3 can slide up and down with respect to the base 2. Since the carriages 31 and 32 are made of resin, lubricity is high with respect to the metal guide rails 21 and 22.

  The slider 3 is disposed on the back side of the base 2 at a distance from the back surface of the base 2. The torsion springs 4 and 5 are disposed between the back surface of the base 2 and the front surface of the slider 3. The first torsion spring 4 is formed by winding a wire, and a winding portion 46 is formed between the arm 41 and the arm 42. However, the first torsion spring 4 may be simply formed by folding the wire in half, or a plate material. Folded in half. The same applies to the second torsion spring 5.

  The distal end portion of one arm 41 of the first torsion spring 4 is rotatable with respect to the slider 3 by a connecting pin 43 and is connected to the front surface of the slider 3. Specifically, the connecting pin 43 is rotatable around its central axis and attached to the tip of the arm 41 of the first torsion spring 4, and the connecting pin 43 is fixed to the front surface of the slider 3. Yes. The central axis of the connecting pin 43 is perpendicular to the front surface of the slider 3 and extends in the front-rear direction. The connection pin 43 may be attached to the front surface of the slider 3 so as to be rotatable around its axis. Further, if the connecting pin 43 is rotatable with respect to the slider 3, the connecting pin 43 may not be rotatable with respect to the arm 41 of the first torsion spring 4.

  The tip of the other arm 42 of the first torsion spring 4 is provided so as to be movable along the guide 23 by a slide pin 44. Specifically, the slide pin 44 is rotatable around the axis of the center line and is attached to the distal end portion of the arm 42 of the first torsion spring 4, and the slide pin 44 is inserted into the guide 23. Is slidable along the guide 23. Since the slide pin 44 is slidable along the guide 23, the distal end portion of the arm 42 of the first torsion spring 4 is guided by the guide 23.

  The connecting pin 43, which is a connecting portion between the arm 41 of the first torsion spring 4 and the slider 3, is on the left side of the guide 23, and the first hooking portion 25 is related to the first guiding portion 24 from the upper end of the first guiding portion 24. It is bent to the opposite side of the connecting pin 43. The connecting pin 43 may be on the right side of the guide 23. In this case, the first hooking portion 25 of the guide 23 is bent leftward from the upper end of the first guiding portion 24.

  The tip of one arm 51 of the second torsion spring 5 is connected to the front surface of the slider 3 by the connecting pin 53 in the same manner as the arm 41 of the first torsion spring 4 is pivotally supported by the connecting pin 43 on the front surface of the slider 3. It is pivotally supported by. Further, the tip of the other arm 52 of the second torsion spring 5 is moved by the slide pin 54 in the same manner as the arm 42 of the first torsion spring 4 can be moved along the guide 23 by the slide pin 44. It can move along the guide 26. A connecting pin 53 that is a connecting portion between the arm 51 of the second torsion spring 5 and the slider 3 is on the right side of the guide 26. The connecting pin 53 may be on the left side of the guide 26. In this case, the second hooking portion 28 of the guide 26 is bent to the right from the lower end of the second guiding portion 27.

  The range in which the slider 3 slides with respect to the base 2 is such that the connecting pin 53 is located above the upper end of the guide 23 (the protruding end of the first hooking portion 25) and the connecting pin 53 is at the lower end of the guide 26 (second hooking portion) This is a range up to a position lower than the no. Further, the position of the slider 3 when the upper end of the guide 23 and the upper and lower positions of the connecting pin 43 are aligned is larger than the position of the slider 3 when the lower end of the guide 26 and the upper and lower position of the connecting pin 53 are aligned. Above.

  When the slider 3 is in a position where the upper end of the guide 23 and the upper and lower positions of the connecting pin 43 are aligned (hereinafter, this position is referred to as a first load specific position), the slip pin 44 is caught by the first hooking portion 25. The upper and lower positions of the slide pin 44 and the connecting pin 43 are aligned at the protruding end. At the first load singular position, since the sliding pin 44 and the connecting pin 43 are closest, the first torsion spring 4 is most engulfed and the bending angle of the first torsion spring 4 is the largest. In the first load singular position, the slide pin 54 is in the second guide portion 27, and the second torsion spring 5 is in a natural state. If the slider 3 is above the first load singular position, the slider 3 is biased upward with respect to the base 2 by the biasing force of the first torsion spring 4. On the other hand, if the slider 3 is below the first load singular position and the sliding pin 44 is hooked on the first hooking portion 25, the slider 3 is lowered with respect to the base 2 by the urging force of the first torsion spring 4. Be energized by.

  When the slider 3 is in a position where the lower end of the guide 26 and the upper and lower positions of the connecting pin 53 are aligned (hereinafter, this position is referred to as a second load specific position), the slip pin 54 is caught by the second hooking portion 28. Located at the protruding end, the upper and lower positions of the slide pin 54 and the connecting pin 53 are aligned. At the second load singular position, since the sliding pin 54 and the connecting pin 53 are closest, the second torsion spring 5 is most engulfed and the bending angle of the second torsion spring 5 is the largest. Moreover, in the 2nd load singular position, the slide pin 44 exists in the 1st guide part 24, and the 1st torsion spring 4 is in a natural state. If the slider 3 is below the second load specific position, the slider 3 is urged downward with respect to the base 2 by the urging force of the second torsion spring 5. On the other hand, if the slider 3 is above the second load singular position and the slide pin 54 is hooked on the second hooking portion 28, the slider 3 is lifted with respect to the base 2 by the urging force of the second torsion spring 5. Be energized by.

  As shown in FIG. 1, when the position of the slider 3 is a predetermined position between the first load singular position and the second load singular position (hereinafter, this position is referred to as an origin position), the slip pin 44 is The sliding pin 54 is positioned at the protruding end of the second hooking portion 28, and the sliding pins 44, 54 are hooked on the hooking portions 25, 28, respectively. When the slider 3 is at the origin position, the torsion springs 4 and 5 are both slightly wound from the natural state, and the torsion springs 4 and 5 are balanced.

  A resin-made elastic convex portion 71 is attached to the front surface of the slider 3, and two protrusions 72 and 73 are formed on the back surface of the base 2 so as to be aligned vertically. As shown in FIG. 1, when the slider 3 is at the origin position, the elastic convex portion 71 is sandwiched between the protrusion 72 and the protrusion 73 in the vertical direction. Therefore, the slider 3 is held at the origin position (see FIG. 5). 5 is a cross-sectional view of the VV cross section shown in FIG.

  At the position where the upper end of the slider 3 and the upper end of the base 2 are aligned (hereinafter referred to as the uppermost position), the connecting pins 43 and 53 are positioned above the upper ends of the guides 23 and 26 as shown in FIG. Further, when the slider 3 is in the uppermost position, the slide pin 54 is disengaged from the second hooking portion 28 and is in the second guide portion 27. When the slider 3 is at the uppermost position, the second torsion spring 5 is in a natural state. When the slider 3 is in the uppermost position, the sliding pin 44 is positioned at the protruding end of the first hooking portion 25, and the first torsion spring 4 is wound more than the natural state.

  At the position where the lower end of the slider 3 and the lower end of the base 2 are aligned (hereinafter referred to as the lowest position), the connecting pins 43 and 53 are positioned below the lower ends of the guides 23 and 26 as shown in FIG. When the slider 3 is in the lowest position, the slide pin 44 is disengaged from the first hook portion 25 and is in the first guide portion 24. Further, when the slider 3 is at the lowest position, the first torsion spring 4 is in a natural state. When the slider 3 is in the lowermost position, the sliding pin 54 is positioned at the protruding end of the second hooking portion 28, and the second torsion spring 5 is wound more than the natural state.

  The slide mechanism 1 configured as described above is incorporated in a portable electronic device 8 as shown in FIGS. The electronic device 8 is a mobile phone, a personal computer, a digital camera, a PDA (Personal Digital Assistance), an electronic notebook, a portable wireless device, or other electronic devices. In addition to the slide mechanism 1, the electronic device 8 includes a front casing 80 and a rear casing 90 that are slidably connected to each other by the slide mechanism 1. In FIG. 6, the front housing 80 is indicated by a two-dot chain line so that the slide mechanism 1 is illustrated.

  A rectangular opening 84 is formed on the rear surface of the front housing 80. The base 2 is fitted into the opening 84, the opening 84 is closed by the base 2, and the base 2 is attached to the front housing 80 by screws. Further, a part of the slider 3 enters the opening 84, and the slider 3 is attached to the front surface of the rear housing 90 by screws. Therefore, the range in which the slider 3 can slide is a range from a position where the upper end of the slider 3 is in contact with the upper wall surface 85 of the opening 84 to a position where the lower end of the slider 3 is in contact with the lower wall surface 86 of the opening 84.

  An input unit 81 having a plurality of push buttons 82 and the like is provided on the front surface of the front housing 80 and below the front housing 80. A display unit 83 having a liquid crystal display, an EL display, or the like is provided on the front surface of the front casing 80 and above the input unit 81.

  A first input unit 92 having a plurality of push buttons 91 and the like is provided on the front surface of the rear housing 90 and above the slider 3. A second input unit 94 having a plurality of push buttons 93 and the like is provided on the front surface of the rear housing 90 and below the slider 3. Note that the input units 92 and 94 may be direction input devices (for example, a trackball pointing device, an optical pointing device, or a capacitive pointing device). A display unit may be provided instead of or together with the input units 92 and 94, or a transparent touch sensor may be provided on the display surface. In addition, instead of the input units 92 and 94 or together with the input units 92 and 94, a camera unit having an imaging element, a lens, and the like may be provided.

  When the slider 3 is at the origin position as shown in FIG. 1, the upper and lower positions of the upper end of the front casing 80 and the upper end of the rear casing 90 are aligned as shown in FIG. The upper and lower positions of the lower end of the rear casing 90 and the lower end of the rear housing 90 are aligned. Therefore, the entire front surface of the rear housing 90 is covered with the front housing 80, and the input units 92 and 94 are hidden behind the front housing 80.

  When the slider 3 is at the uppermost position as shown in FIG. 2, the upper end of the rear casing 90 is shifted upward with respect to the upper end of the front casing 80 as shown in FIG. Of these, the portion above the slider 3 is located above the front housing 80. Therefore, the first input unit 92 is exposed.

  When the slider 3 is at the lowest position as shown in FIG. 3, the lower end of the rear casing 90 is shifted downward with respect to the lower end of the front casing 80 as shown in FIG. Of these, the part below the slider 3 is located below the front housing 80. Therefore, the second input unit 94 is exposed.

  Next, the operation method and operation of the slide mechanism 1 and the electronic device 8 will be described.

(1) When the slider 3 slides from the origin position to the uppermost position When the user slides the front casing 80 downward with respect to the rear casing 90 from the state where the slider 3 is at the origin position, the slider 3 moves to the base 2. Slide up. When the slider 3 starts to slide upward, the elastic convex portion 71 is elastically deformed and gets over the protrusion 72.

  As the slider 3 moves upward, the connecting pins 43 and 53 move upward. If it does so, the 2nd torsion spring 5 will be in a natural state by the movement on the connection pin 53, the slip pin 54 will remove | deviate from the 2nd hook part 28, and will move to the 2nd guide part 27. Since the second hooking portion 28 is bent to the opposite side of the connecting pin 53, the slip pin 54 is easily detached from the second hooking portion 28. On the other hand, since the connecting pin 43 approaches the slip pin 44, the first torsion spring 4 is wound and the bending angle thereof is increased.

  Further, the user slides the front casing 80 downward relative to the rear casing 90, and the slider 3 slides upward relative to the base 2. Then, while the second torsion spring 5 is kept in a natural state, the slide pin 54 moves upward along the second guide portion 27, and the connecting pin 43 moves upward so that the first torsion spring 4 is further wound. It is. Thus, when the slider 3 moves above the first load singular position, the connecting pin 43 rises above the slide pin 44, so that the slider 3 is biased upward with respect to the base 2 by the first torsion spring 4. Is done. Therefore, the first torsion spring 4 naturally slides the slider 3 upward with respect to the base 2, and the front casing 80 naturally slides downward with respect to the rear casing 90.

When the slider 3 moves to the uppermost position, all the push buttons 91 of the first input unit 92 are exposed, and the carriages 31 and 32 of the slider 3 come into contact with the upper wall surface 85 of the opening 84 of the front housing 80. Therefore, even if the first torsion spring 4 is wound more than the natural state, the slider 3 does not move further upward with respect to the base 2, and the front casing 80 moves further downward with respect to the rear casing 90. Do not move.
As described above, it is not necessary for the user to slide the slider 3 from the origin position to the uppermost position, and it is only necessary to slide the slider 3 to the first load singular position. Therefore, it is not necessary for the user to slide the front casing 80 and the slider 3 for a long distance. Therefore, the user can easily open the front housing 80 downward only with the fingertip.

(2) When the slider 3 slides from the uppermost position to the origin position When the user slides the front casing 80 upward relative to the rear casing 90, the slider 3 slides downward relative to the base 2. As the slider 3 moves downward, the connecting pins 43 and 53 move downward. Then, the sliding pin 54 moves downward along the second guide portion 27 while the second torsion spring 5 is kept in a natural state, and the first torsion spring 4 is wound.

  When the slider 3 moves below the first load singular position, the slider 3 is urged downward with respect to the base 2 by the first torsion spring 4. Therefore, the first torsion spring 4 naturally slides the slider 3 downward with respect to the base 2, and the front casing 80 naturally slides upward with respect to the rear casing 90. Since the slider 3 naturally slides from the first load singular position toward the origin position, the user need not slide the front casing 80 and the slider 3 for a long distance.

  Further, when the slider 3 slides downward with respect to the base 2, the sliding pin 54 moves downward along the second guide portion 27 in a state where the second torsion spring 5 maintains a natural state, and the first torsion spring 4. The bending angle of becomes smaller. Then, the sliding pin 54 enters the second hooking portion 28, hits the protruding end of the second hooking portion 28, and the second torsion spring 5 is wound.

  When the slider 3 moves to the origin position, the first torsion spring 4 and the second torsion spring 5 are balanced, and the slider 3 stops with respect to the base 2. Immediately before the slider 3 returns to the origin position, the elastic projection 71 is elastically deformed to get over the projection 72, and when the slider 3 is located at the origin position, the elastic projection 71 is sandwiched between the projection 72 and the projection 73 up and down.

(3) When the slider 3 slides from the origin position to the lowest position When the user slides the front casing 80 upward with respect to the rear casing 90, the slider 3 slides downward with respect to the base 2. When the slider 3 starts to slide downward, the elastic convex portion 71 is elastically deformed and gets over the protrusion 73.

  As the slider 3 moves downward, the connecting pins 43 and 53 move downward. If it does so, the 1st torsion spring 4 will be in a natural state by the movement below the connection pin 43, the slip pin 44 will remove | deviate from the 1st hook part 25, and will move to the 1st guide part 24. Since the first hook portion 25 is bent to the opposite side of the connecting pin 43, the slip pin 44 is easily detached from the first hook portion 25. On the other hand, since the connecting pin 53 approaches the slip pin 54, the second torsion spring 5 is wound, and the bending angle thereof is increased.

  Further, the user slides the front casing 80 upward with respect to the rear casing 90, and the slider 3 slides downward with respect to the base 2. Then, while the first torsion spring 4 is kept in a natural state, the slide pin 44 moves downward along the first guide portion 24, and the connecting pin 53 moves downward, so that the second torsion spring 5 is further wound. It is. Thus, when the slider 3 moves below the second load singular position, the slider 3 is urged downward with respect to the base 2 by the second torsion spring 5. Therefore, the slider 3 is naturally slid downward with respect to the base 2 by the second torsion spring 5, and the front casing 80 is naturally slid upward with respect to the rear casing 90. Since the slider 3 naturally slides from the second load singular position toward the lowest position, the user need not slide the front casing 80 and the slider 3 for a long distance.

  When the slider 3 moves to the lowest position, all the push buttons 93 of the second input unit 94 are exposed, and the carriages 31 and 32 of the slider 3 come into contact with the lower wall surface 86 of the opening 84 of the front housing 80. For this reason, even if the second torsion spring 5 is wound more naturally than the natural state, the slider 3 does not move further downward with respect to the base 2, and the front casing 80 moves further upward with respect to the rear casing 90. Do not move.

(4) When the slider 3 slides from the lowest position to the origin position When the user slides the front casing 80 downward relative to the rear casing 90, the slider 3 slides upward relative to the base 2. As the slider 3 moves upward, the connecting pins 43 and 53 move upward. Then, the sliding pin 44 moves upward along the first guide portion 24 with the first torsion spring 4 kept in a natural state, and the second torsion spring 5 is wound.

  When the upper and lower positions of the connecting pin 53 and the sliding pin 54 are aligned, and the connecting pin 53 moves further above the sliding pin 44, the slider 3 is biased upward with respect to the base 2 by the second torsion spring 5. The Therefore, the slider 3 is naturally slid upward with respect to the base 2 by the second torsion spring 5, and the front casing 80 is naturally slid downward with respect to the rear casing 90. Thus, since the slider 3 naturally slides from the second load singular position toward the origin position, the user does not have to slide the front casing 80 and the slider 3 for a long distance.

  Further, when the slider 3 slides upward with respect to the base 2, the slide pin 44 moves upward along the first guide portion 24 in a state where the first torsion spring 4 is kept in a natural state, and the second torsion spring 5. The bending angle of becomes smaller. Then, the sliding pin 44 enters the first hook portion 25, hits the protruding end of the first hook portion 25, and the first torsion spring 4 is wound.

  When the slider 3 moves to the origin position, the first torsion spring 4 and the second torsion spring 5 are balanced, and the slider 3 stops with respect to the base 2. Immediately before the slider 3 returns to the origin position, the elastic projection 71 is elastically deformed to overcome the protrusion 73, and when the slider 3 is positioned at the origin position, the elastic protrusion 71 is sandwiched between the protrusion 72 and the protrusion 73 vertically.

  As described above, according to the present embodiment, when the user slides the front housing 80 from the state of FIG. 6 to the state of FIG. 7 or vice versa, the load is smoothly reduced by the urging force of the first torsion spring 4. Operation becomes possible. Similarly, the front casing 80 can be slid from the state of FIG. 6 to the state of FIG. 8 or vice versa with a low load for the user by the biasing force of the second torsion spring 5.

  Further, when the slider 3 is at the uppermost position as shown in FIG. 2, the position of the arm 42 and the slide pin 44 of the first torsion spring 4 is determined by the slide pin 44 being hooked on the first hook portion 25. Therefore, the first torsion spring 4 can be in a state of being wound from a natural state. In this state, the slider 3 is urged upward with respect to the base 2 by the first torsion spring 4, and the upper end of the slider 3 hits the upper wall surface 85 of the opening 84 of the front housing 80, and the slider 3 moves upward. It is regulated. Accordingly, the slider 3 does not rattle with respect to the base 2, and the state shown in FIG. 7 is maintained even when natural vibrations or loads act on the electronic device 8. Similarly, when the slider 3 is at the lowest position as shown in FIG. 3, the slider 3 is not rattled against the base 2 by the second torsion spring 5, and the front housing 80 is also against the rear housing 90. I can't play.

  Further, when the slider 3 is at the origin position as shown in FIG. 1, the torsion springs 4 and 5 can be balanced by the sliding pins 44 and 54 being hooked on the hook portions 25 and 28. Therefore, the slider 3 can be held at the origin position, and the electronic device 8 can be held in the state shown in FIG. In particular, since the elastic convex portion 71 is between the protrusions 72 and 73, the slider 3 can be held at the origin position without the slider 3 rattling with respect to the base 2.

  Further, the origin position of the slider 3 can be adjusted up and down by changing the arm length of the torsion springs 4 and 5, the angle of the arm in the natural state, the spring constant, and the like. If the mounting position of the slider 3 with respect to the rear housing 90 is adjusted up and down in accordance with the origin position of the slider 3, the rear housing 90 is moved from the upper end of the front housing 80 when the front housing 80 slides to the lowest position. The length to the upper end can be adjusted, and the length from the lower end of the front casing 80 to the lower end of the rear casing 90 when the front casing 80 slides to the top can be adjusted.

  In addition, a display unit 83 is provided on the front surface of the front housing 80, a first input unit 92 is provided on the upper front surface of the rear housing 90, and a second input unit 94 is provided on the lower front surface of the rear housing 90. Therefore, the function of the electronic device 8 can be switched according to the form of the electronic device 8. That is, when the front casing 80 is slid down to expose the first input section 92 and when the front casing 80 is slid up to expose the second input section 94, the electronic device 8 If the functions are different, it is possible to provide the electronic device 8 that can be used by switching the functions.

  Further, since the guides 23 and 26 are independent from each other, the lengths of the guides 23 and 26 can be set independently. If the slider 3 can move further upward than the uppermost position without the slider 3 coming into contact with the upper wall surface 85 of the opening 84 of the front casing 80, the upper limit of movement of the slider 3 is limited. The slip pin 54 is in contact with the upper end of the second guide portion 27. Therefore, by changing the design of the length of the second guide portion 27, the range in which the front housing 80 can slide down relative to the rear housing 90 can be changed. Similarly, when the slider 3 can move further below the lowest position without the slider 3 coming into contact with the lower wall surface 86 of the opening 84 of the front casing 80, If the design of the length is changed, the range in which the front casing 80 can slide upward with respect to the rear casing 90 can be changed. As described above, since the lengths of the guide portions 24 and 27 can be set independently, the sliding range from the state in which the front casing 80 is overlapped with the rear casing 90 to the upper side and the front casing 80 is rearward. The sliding range from the state of overlapping the housing 90 to the bottom can be set separately.

In addition, this invention is not limited to the said embodiment, What changed various design with respect to the said embodiment is also contained in the scope of the present invention. Hereinafter, although a modification is given, the scope of the present invention is not limited to the following modification.
In the above embodiment, the guide portions 24 and 27 are parallel to the sliding direction of the slider 3. However, if the guide portions 24 and 27 are not perpendicular to the sliding direction of the slider 3, it is not always necessary to be parallel. Absent.
Moreover, in the said embodiment, although the guide parts 24 and 27 were mutually parallel, it does not necessarily need to be parallel.
Further, in the above embodiment, the elastic convex portion 71 is provided on the front surface of the slider 3 and the protrusions 72 and 73 are provided on the back surface of the base 2, but conversely, the elastic convex portion 71 is provided on the back surface of the base 2. The protrusions 72 and 73 may be provided on the front surface of the slider 3. When the elastic convex portion 71 is provided on the back surface of the base 2, the elastic convex portion 71 prevents the movements of the torsion springs 4 and 5 from interfering with each other.

Further, both or one of the torsion springs 4 and 5 may be changed to a compression spring. When a compression spring is used instead of the first torsion spring 4, one end of the compression spring is provided on the slide pin 44 so as to be movable along the guide 23, as in the case of the first torsion spring 4. The other end of the slider is pivotally supported by the connecting pin 43 on the front surface of the slider 3. When the slider 3 is at the origin position or the uppermost position as shown in FIG. 1 or FIG. 2, the compression spring is compressed, the slider 3 is below the origin position, and the slide pin 44 is the first hooking portion. When it deviates from 25, the compression spring is in a natural state. Even when a compression spring is used instead of the second torsion spring 5, one end of the compression spring is provided so as to be movable along the guide 26 by the slide pin 54, as in the case of the second torsion spring 5. The portion is pivotally supported by the connecting pin 53 on the front surface of the slider 3. When the slider 3 is at the origin position or the lowest position as shown in FIG. 1 or FIG. 3, the compression spring is compressed, the slider 3 is above the origin position, and the sliding pin 54 is connected to the second hook 28. When it comes off, the compression spring is in its natural state.
Further, the spring is not limited to a metal spring, and may be a rubber spring, an air spring or another spring.
