- the shape and structure of the main body 11 are not particularly limited as long as the main body 11 can serve as a base on which the elastic claws 12 are provided and can hold the guide rail 2.
- the main body 11 is configured as a plate-like member having a first surface 11a and a second surface 11b opposite the first surface 11a, as shown in Fig. 3. Note that the first surface 11a and the second surface 11b do not need to be flat surfaces, and may have irregularities on the surface, or may be curved rather than flat. In this embodiment, the first surface 11a and the second surface 11b are parallel to each other, but may be non-parallel to each other.
- the carrier plate 1 (main body 11) has a first fitting portion 111a into which the first cable C1 fits, and a second fitting portion 111b into which the second cable C2 fits.
- One end C11 of the first cable C1 engages with the first fitting portion 111a
- one end C21 of the second cable C2 engages with the second fitting portion 111b.
- the first fitting portion 111a and the second fitting portion 111b may be provided with an elastic member, such as a spring for stretching the cable C.
- the first fitting portion 111a is provided on the opposite side in the width direction from the elastic claw 12 across the guide rail 2, which is the second member
- the second fitting portion 111b is also provided on the opposite side in the width direction from the elastic claw 12 across the guide rail 2, which is the second member.
- the first fitting portion 111a and the second fitting portion 111b are not provided at a position overlapping the guide rail 2 in the width direction, but are located outside the guide rail 2 with respect to the side edge of the guide rail 2 in the width direction.
- the second fitting portion 111b is provided at a position offset in the width direction from the first fitting portion 111a, but the first fitting portion 111a and the second fitting portion 111b may be located at the same position in the width direction (positions spaced the same distance apart in the width direction from the side edge of the guide rail 2).
- the main body 11 has an engagement claw 112 with which the other of the two widthwise side portions of the guide rail 2 (second engaged portion 21b) engages.
- the other of the two widthwise side portions of the guide rail 2 (second engaged portion 21b) engages with the engagement claw 112, and one widthwise side of the guide rail 2 (first engaged portion 21a) engages with the elastic claw 12, completing the connection of the guide rail 2 to the carrier plate 1 (see solid lines in FIG. 3; connection completed position).
- the engagement claw 112 engages in the thickness direction of the guide rail 2 so that the carrier plate 1 can move along the guide rail 2, but does not engage in the length direction of the guide rail 2.
- FIG. 1 As shown in FIG.
- an engagement recess 14 into which the second engaged portion 21b of the guide rail 2 fits is provided on one surface 11a of the main body 11, and the engagement claw 112 is provided to face the second engaged portion 21b that fits into the engagement recess 14 in the thickness direction of the guide rail 2.
- the engaging claw may have other configurations, such as an engaging claw protruding from one surface 11a of the main body 11, as long as it can engage with the guide rail 2.
- the guide rail 2 rotates toward the elastic claw 12 from the state shown by the two-dot chain line in FIG. 3 to the state shown by the solid line, using the engaging point with the engaging claw 112 (inside the engaging recess 14) as a fulcrum (moves in the moving direction MD1 (see FIG. 3)).
- a part of the guide rail 2 (the first engaged portion 21a) engages with the elastic claw 12, and the guide rail 2 is connected to the carrier plate 1.
- the elastic claw 12 elastically deforms when it is connected to the guide rail 2, which is the second member. Specifically, when the guide rail 2 moves in a predetermined moving direction MD1 relative to the carrier plate 1 (or the carrier plate 1 moves relative to the guide rail 2), the elastic claw 12 elastically deforms (see FIG. 7), allowing the guide rail 2 to move to the final connection completion position (see the solid line in FIG. 3). When the guide rail 2 reaches the final connection completion position, the elastic claw 12 elastically returns to its initial state and engages with the guide rail 2. This prevents the guide rail 2 from coming off the carrier plate 1.
- the elastic claw 12 engages with one of the two widthwise side portions of the guide rail 2 (first engaged portion 21a), and the engaging claw 112 engages with the other widthwise side (second engaged portion 21b) of the guide rail 2. This prevents the guide rail 2 from coming off the carrier plate 1.
- the elastic claw 12 is made of a resin material formed integrally with the main body 11. As will be described in detail later, as shown in FIG. 7, when the guide rail 2, which is the second member, is connected to the carrier plate 1, which is the first member, the guide rail 2 presses the pressed portion 122a of the elastic claw 12, which will be described later, so that the elastic claw 12 is bent in a first rotation direction RD1 about the rotation center RC.
- the rotation center RC of the elastic claw 12 is a connection part with the main body 11, where the entire elastic claw 12 bends to change its posture when a force is applied to the elastic claw 12, which is integral with the main body 11.
- the elastic claw 12 is configured to be elastically deformed mainly at the rotation center RC, and the entire elastic claw 12 rotates around the rotation center RC (see FIG. 7).
- the part that is the rotation center RC of the elastic claw 12 has lower rigidity than other parts of the elastic claw 12 (e.g., arm part 121 and claw part 122, which will be described later, other than the parts around the rotation center RC), and is configured to be more easily deformed than other parts of the elastic claw 12 when a force is applied to the elastic claw 12 from the guide rail 2.
- the elastic claw 12 is configured to rotate around the rotation center RC. Note that when the elastic claw 12 rotates around the rotation center RC, other parts of the elastic claw 12 (e.g., arm part 121 and claw part 122) may also deform slightly.
- the rotation direction RD1 the direction in which the pressed portion 122a of the elastic claw 12 is pressed and rotated by the guide rail 2
- the rotation direction opposite to the first rotation direction RD1 is referred to as the second rotation direction RD2.
- the elastic claw 12 has an arm portion 121 extending from the center of rotation RC and a claw portion 122 provided at the end of the arm portion 121 opposite the center of rotation RC.
- the arm portion 121 is a portion that extends from the rotation center RC to the claw portion 122.
- the arm portion 121 is configured to rotate mainly around the rotation center RC.
- the shape and structure of the arm portion 121 are not limited to the structure shown in the figure.
- the arm portion 121 includes a first extension portion 121a and a second extension portion 121b, as shown in Figures 4 and 5B.
- the first extension portion 121a protrudes from the first surface 11a in the thickness direction D1 of the main body 11, which is the direction connecting the first surface 11a and the second surface 11b.
- the first extension portion 121a is connected to the second extension portion 121b, and in this embodiment, the first extension portion 121a and the second extension portion 121b are arranged in a substantially L-shape.
- a claw portion 122 protrudes from the end of the first extension portion 121a opposite to the end connected to the second extension portion 121b.
- the direction along the width direction of the guide rail 2 is called the width direction D2 of the main body 11
- the direction along the longitudinal direction of the guide rail 2 is called the height direction D3 of the main body 11.
- the thickness direction D1 of the main body 11 can be said to be the thickness direction of the guide rail 2
- the width direction D2 of the main body 11 can be said to be the width direction of the guide rail 2
- the height direction D3 of the main body 11 can be said to be the longitudinal direction of the guide rail 2.
- the first extension portion 121a is configured to have higher rigidity than the second extension portion 121b. In this case, the amount of deformation of the first extension portion 121a when the elastic claw 12 is pressed by the guide rail 2 is suppressed, making it easier for the entire elastic claw 12 to rotate around the rotation center RC.
- the first extension portion 121a is formed in a columnar (rectangular columnar) shape, and has higher rigidity than the plate-shaped second extension portion 121b.
- the second extension portion 121b extends from the first extension portion 121a toward the rotation center RC.
- the second extension portion 121b extends in the same direction (to the right in FIG. 5B) as the protruding direction of the claw portion 122 from the first extension portion 121a, as shown in FIG. 5B.
- the second extension portion 121b is configured so that the cross-sectional area at the portion that becomes the rotation center RC (the connection portion between the second extension portion 121b and the main body 11) is smaller than that of other portions of the second extension portion 121b.
- the rotation center RC which is the connection portion between the second extension portion 121b and the main body 11, is more likely to be elastically deformed, and the entire elastic claw 12 is more likely to rotate around the rotation center RC.
- the second extension portion 121b is configured by a plate-like body extending from the first extension portion 121a toward the main body 11, as shown in FIG. 4 and FIG. 5A. At the connection portion between the second extension portion 121b and the main body 11, the width is narrower than other portions of the second extension portion 121b, so that the cross-sectional area is smaller.
- the narrow portion 121c which is the connection portion between the second extension portion 121b and the main body 11, is more easily deformed than other portions of the second extension portion 121b, and becomes the rotation center RC of the elastic claw 12.
- the second extension portion 121b is composed of a pair of plate-like bodies arranged at a distance in the height direction D3 of the main body 11 (the longitudinal direction of the guide rail 2).
- the narrow portion 121c protrudes in the thickness direction D1 of the main body 11 from the base end E (see FIG.
- connection portion 113 of the main body 11 extends from the first surface 11a side of the wall portion WL facing the base end E of the second extension portion 121b toward the second extension portion 121b among the walls that define the recess CP described later. Between the base end E of the second extension portion 121b and the wall portion WL (below the connection portion 113 in FIG. 5B), a gap is provided in the width direction D2 of the main body 11.
- the rotation center RC is shown by one point for convenience of explanation, but the rotation center does not need to be only the point shown.
- the elastic claw 12 has a first extension portion 121a and a second extension portion 121b, and is configured to be approximately L-shaped when viewed in the height direction D3 of the main body 11, but the elastic claw may have other shapes other than approximately L-shaped, such as a curved approximately C-shape.
- the claw portion 122 has a pressed portion 122a that comes into contact with and is pressed by the guide rail 2 when the guide rail 2, which is the second member, moves in the moving direction MD1, and an engaging portion 122b that is located on the side of the guide rail 2 in the detachment direction MD2, which is the opposite direction to the moving direction MD1, and is capable of engaging with the guide rail 2 when the guide rail 2 is in the connection completion position (see solid line in FIG. 3 and FIG. 6) in which the guide rail 2 is connected to the carrier plate 1.
- the pressed portion 122a is a portion that comes into contact with the guide rail 2 when the guide rail 2 moves from a state before being connected to the carrier plate 1 to a connection completion position.
- the pressed portion 122a is configured to convert the force applied to the elastic claw 12 from the guide rail 2 into a force in the first rotation direction RD1 when pressed by the guide rail 2 moving in the movement direction MD1.
- the pressed portion 122a is inclined with respect to the movement direction MD1 so that the component of the force applied from the pressing portion 21e of the guide rail 2 to the pressed portion 122a faces the first rotation direction RD1 at the contact point between the guide rail 2 and the pressed portion 122a.
- the elastic claw 12 rotates in the first rotation direction RD1 around the rotation center RC.
- the engaging portion 122b When the guide rail 2 is in the connection completion position, the engaging portion 122b is located on the side of the guide rail 2 in the removal direction MD2 (upper side in FIG. 6), which is the opposite direction to the movement direction MD1. As a result, the engaging portion 122b engages with the guide rail 2 (first engaged portion 21a) in the thickness direction D1 of the main body 11, and holds the guide rail 2 in the connection completion position.
- the carrier plate 1 is provided with an auxiliary claw 15 that sandwiches the first engaged portion 21a of the guide rail 2 between the engaging portion 122b and the carrier plate 1 in the thickness direction D1 of the main body 11.
- the auxiliary claw 15 protrudes in a cantilever manner from the first surface 11a of the main body 11 toward the engaging portion 122b, and is configured to be elastically deformable in the moving direction MD1.
- the auxiliary claw 15 presses the first engaged portion 21a toward the engaging portion 122b, and sandwiches the first engaged portion 21a of the guide rail 2 together with the engaging portion 122b. This holds the guide rail 2 in a state where rattling is suppressed.
- the auxiliary claw 15 may have another configuration, or may not be provided at all.
- the "direction of force F1 applied from the guide rail 2 to the engaging portion 122b" refers to the direction of the force acting on the engaging portion 122b at the contact site between the first engaged portion 21a of the guide rail 2 and the engaging portion 122b when the guide rail 2 receives a force in the removal direction MD2.
- the force F1 is a force applied from the guide rail 2 to the engaging portion 122b when a force is applied to move the guide rail 2 relative to the carrier plate 1, but it may be a force applied from the guide rail 2 to the engaging portion 122b when a force is applied to move the carrier plate 1 relative to the guide rail 2, or a force applied from the guide rail 2 to the engaging portion 122b when a force is applied to both the carrier plate 1 and the guide rail 2.
- the virtual line L is an extension line of a line (a rotation radius of a virtual circle CC described later) connecting the rotation center RC and the contact portion of the guide rail 2 (the first engaged portion 21a) and the engaging portion 122b.
- FIG. 6 the virtual line L is an extension line of a line (a rotation radius of a virtual circle CC described later) connecting the rotation center RC and the contact portion of the guide rail 2 (the first engaged portion 21a) and the engaging portion 122b.
- the virtual circle indicated by the reference symbol CC is a circle extending the rotation locus of the contact portion between the first engaged portion 21a of the guide rail 2 and the engaging portion 122b when the elastic claw 12 rotates around the rotation center RC.
- the force F1 applied from the guide rail 2 can be broken down into a force F2 along the imaginary line L and a force F3 along the tangent direction of the imaginary circle CC, and the force F3 along the tangent direction of the imaginary circle CC acts on the elastic claw 12 in the second rotation direction RD2.
- the elastic claw 12 receives a force that rotates in the second rotation direction RD2.
- the position of the rotation center RC is set so that the elastic claw 12 receives a force F3 from the guide rail 2 that rotates in the second rotation direction RD2, as described above.
- the elastic claw 12 even if a force in the removal direction MD2 is applied to the guide rail 2, the elastic claw 12 does not receive a force that rotates in the first rotation direction RD1, which is the rotation direction in which the engagement is released, but receives a force in the second rotation direction RD2 (clockwise in Figure 8), which is the direction in which the engagement is strengthened. Therefore, the engagement between the elastic claw 12 and the guide rail 2 becomes more difficult to release.
- FIG. 9 shows a reference example in which the elastic claw 120 extends perpendicularly from the first surface 110a of the main body 110 of the carrier plate 10.
- the direction of the force F10 applied from the guide rail 20 to the engagement portion 1220b is in the first rotation direction RD1 with respect to the imaginary line Lr passing through the rotation center RC and the engagement portion 1220b.
- the force F10 applied from the guide rail 20 can be decomposed into a force F20 along the imaginary line Lr and a force F30 along the tangent direction of the imaginary circle Cr, and the force F30 along the tangent direction of the imaginary circle Cr acts on the elastic claw 120 in the first rotation direction RD1.
- the direction in which the elastic claw 120 rotates when the guide rail 20 is connected and the direction in which the elastic claw 120 rotates when the guide rail 20 is about to be detached are the same (first rotation direction RD1). Therefore, when a force in the detachment direction MD2 is applied to the guide rail 20, the elastic claw 120 rotates in the first rotation direction RD1, which is a direction in which the engagement between the elastic claw 120 and the guide rail 20 is released, and the guide rail 20 may be detached. In contrast, in this embodiment, as described above, when a force in the detachment direction MD2 is applied to the guide rail 2, the elastic claw 12 rotates in the second rotation direction RD2, which is a direction in which the engagement between the elastic claw 12 and the guide rail 2 becomes stronger. Therefore, the guide rail 2 is prevented from being detached from the carrier plate 1.
- the direction of the force applied to the elastic claw 12 is opposite when the guide rail 2 is connected and when the guide rail 2 is about to detach. Therefore, even if the entire elastic claw 12 or the area around the rotation center RC is made flexible so that the elastic claw 12 is more likely to elastically deform when the guide rail 2 is connected, the elastic claw 12 will simply be more likely to rotate in the second rotation direction RD2 when the guide rail 2 is about to detach. Therefore, even if the elastic claw is made more likely to deform in order to make it easier to connect the guide rail 2 to the carrier plate 1, it is possible to prevent the guide rail 2 from detaching from the carrier plate 1.
- the elastic claw 120 if the elastic claw 120 is made more flexible by thinning the entire elastic claw 120 or the area around the rotation center RC, the elastic claw 120 will bend more easily when connecting the guide rail 20 to the carrier plate 10, making it easier to connect the guide rail 20.
- the elastic claw 120 rotates in the first rotation direction RD1, so that the guide rail 20 also becomes more easily detached from the carrier plate 10.
- the elastic claw 12 even if the elastic claw 12 is made more elastically deformable to make it easier to assemble the guide rail 2 to the carrier plate 1 with less force, the guide rail 2 does not become more easily detached from the carrier plate 1.
- the carrier plate 1 has a first fitting portion 111a and a second fitting portion 111b provided on the opposite side of the guide rail 2 in the width direction of the guide rail 2 from the elastic claw 12, and the first cable C1 and the second cable C2 fit into the first fitting portion 111a and the second fitting portion 111b, respectively.
- a rotational moment acts around a rotation axis extending in the extension direction of the guide rail 2 at the engagement point between the guide rail 2 and the carrier plate 1.
- the rotational moment is more likely to act, and the carrier plate 1 becomes more likely to come off the guide rail 2.
- the above-mentioned rotational moment applied to the carrier plate 1 becomes a force that rotates the elastic claw 12 in the second rotational direction RD2, making it more difficult to disengage the engagement between the elastic claw 12 and the guide rail 2.
- the first extension portion 121a extends protruding from the first surface 11a in the thickness direction D1 of the main body 11, and the second extension portion 121b extends from the first extension portion 121a toward the rotation center RC in the same direction as the protruding direction of the claw portion 122 from the first extension portion 121a, at a length longer than the protruding amount of the claw portion 122 from the first extension portion 121a.
- the rotation center RC located on the base end E side of the second extension portion 121b is located at a position farther from the first extension portion 121a in the width direction D2 (a position closer to the center of the width direction of the guide rail 2) than the tip end of the claw portion 122 (the contact portion between the engagement portion 122b and the guide rail 2).
- the virtual line L connecting the rotation center RC and the engaging portion 122b inclines away from the center of the width direction of the guide rail 2 as it moves away from the first surface 11a of the main body 11 of the carrier plate 1.
- the force F1 applied from the guide rail 2 to the engaging portion 122b is directed in a direction substantially perpendicular to the first surface 11a (strictly speaking, in a direction slightly inclined toward the center of the guide rail 2 with respect to the direction perpendicular to the first surface 11a). Therefore, when the protrusion amount of the second extension portion 121b from the first extension portion 121a is greater than the protrusion amount of the claw portion 122 from the first extension portion 121a, the component force F3 in the tangential direction of the virtual circle CC is directed in the second rotation direction RD2. This makes it possible to reliably apply a force in the second rotation direction RD2 to the elastic claw 12, and to prevent the guide rail 2 from being released from the carrier plate 1.
- the engaging portion 122b is inclined so as to approach the first surface 11a as it moves from the first extension portion 121a to the tip of the claw portion 122.
- the magnitude of the force toward the second rotation direction RD2 can be made larger compared to when the engaging portion 122b extends parallel to the first surface 11a. That is, the force from the guide rail 2 applied in a direction perpendicular to the surface of the engaging portion 122b is inclined toward the second rotation direction RD2 because the engaging portion 122b is inclined so as to approach the first surface 11a as it moves from the first extension portion 121a to the tip of the claw portion 122.
- the component force F3 in the tangential direction of the virtual circle CC into which the force applied to the engaging portion 122b is resolved is larger compared to when the engaging portion 122b is parallel to the first surface 11a. This makes it possible to prevent the guide rail 2 from coming off the carrier plate 1.
- the main body 11 has a recess CP extending from the first surface 11a toward the second surface 11b.
- a part of the first extension portion 121a and the second extension portion 121b are arranged in this recess CP.
- the recess CP is configured to penetrate from the first surface 11a to the second surface 11b, but the recess CP may be a non-penetrating recess with a bottom.
- a connection structure including a first member and a second member, the second member being connected to the first member by moving relatively to the first member in a predetermined moving direction, the first member being: The main body, an elastic claw extending from the main body and configured to be elastically deformable so as to rotate around a rotation center provided at a connection point with the main body;
- the elastic claw includes an arm portion extending from the rotation center and a claw portion provided at an end of the arm portion opposite to the rotation center, the claw portion includes a pressed portion that is in contact with and pressed by the second member when the second member moves in the moving direction, and an engaging portion that is located on a detachment direction side, which is the opposite direction to the moving direction, with respect to the second member when the second member is in a connection completion position in which the second member is connected to the first member, and is engageable with the second member;
- the elastic claw is configured to bend in a first rotation direction about the rotation center by the second member pressing the pressed portion when the second member is connected to the first member,
- the main body of the first member is a plate-like member having a first surface and a second surface opposite to the first surface,
- the arm portion is a first extension portion that protrudes and extends from the first surface in a thickness direction of the main body, the thickness direction being a direction connecting the first surface and the second surface;
- the connection structure described in (1) is provided with a second extension portion extending from the first extension portion toward the rotation center in the same direction as the protruding direction of the claw portion from the first extension portion, at a length longer than the protruding amount of the claw portion from the first extension portion.
