Description

Technical Field

[0001] The present invention relates to a locking device for an opening and closing body that is attached to an opening of a fixed body so as to be openable and closable, and locks the opening and closing body in a closed state.

Background Art

[0002] For example, an opening and closing body such as a lid is attached to an opening formed in a fixed body such as a glove box of an automobile so as to be openable and closable. And, a locking device is provided between the opening and the opening and closing body so as to lock the opening and closing body when it is closed and to release the lock when the opening and closing body is opened.

[0003] For example, Patent Document 1 below describes a locking device for an opening and closing body having a locking portion, a locking member that engages with and disengages from the locking portion, a case having a support portion, a rotating body pivotally supported on the case rotatably, biasing means for biasing the rotating body to rotate in a first direction, and an elastic member having a support hole into which the support portion is inserted. Further, tapered surfaces that gradually taper the support portion are formed on both outer surfaces in the width direction of the support portion. Furthermore, a stepped locking step portion is formed on the base end side of one tapered surface of the support portion.

[0004] When the elastic member is supported by the support portion, first, the support portion is inserted into the support hole of the elastic member, both tapered surfaces of the support portion are brought into contact with both inner circumferences of the support hole, and the elastic member is temporarily held by the support portion. Then, the elastic member is pushed into the support portion, and the locking step portion of the support portion is locked to the back side peripheral edge of the support hole, so that the elastic member can be supported by the support portion (see FIGS. 13(A) and (B) of Patent Document 1). [[ID=​​​​​​​​​​​​​​​[Problems that the invention aims to solve]

[0006] In the locking device for the opening and closing body described in Patent Document 1, both sides in the width direction of the support portion provided on the case are tapered surfaces. Therefore, when inserting the support portion into the support hole of the elastic member to temporarily hold the elastic member on both tapered surfaces of the support portion in order to support the elastic member with the support portion, the elastic member may tilt relative to the support portion. In this case, problems arise when supporting the elastic member with the support portion using automated equipment rather than manual methods.

[0007] Therefore, the object of the present invention is to provide a locking device for an opening / closing body that can improve the ease of attaching an elastic member to the mounting portion of a case. [Means for solving the problem]

[0008] To achieve the above objective, the present invention provides a locking device for an opening / closing body that is closably attached to an opening of a fixed body, comprising: a locking portion provided on one of the fixed body or the opening / closing body; a locking member disposed on the other of the fixed body or the opening / closing body and engaging with and disengaging from the locking portion; a case disposed on the other of the fixed body or the opening / closing body and having a mounting portion; a rotating body rotatably supported in the case; an elastic member having a mounting hole into which the mounting portion is inserted and attached to the mounting portion; and a biasing means for rotationally biasing the rotating body in a predetermined direction, wherein one side of the mounting portion is provided with a mounting portion that gradually narrows toward the tip in the direction of insertion of the mounting portion into the mounting hole. Furthermore, the mounting portion is provided with a slope that contacts one side of the mounting hole when the mounting portion is inserted into the mounting hole, and on the other side of the mounting portion, there is a first temporary holding portion that is formed substantially parallel to the direction in which the mounting portion is inserted into the mounting hole and contacts the inner circumference of the other side of the mounting hole to temporarily hold the elastic member when the mounting portion is inserted into the mounting hole and the slope contacts one side of the mounting hole, and / or a second temporary holding portion that is formed in a stepped shape and contacts the periphery of the other side of the mounting hole on the back side of the elastic member to temporarily hold the elastic member when the mounting portion is inserted into the mounting hole and the slope contacts one side of the mounting hole. [Effects of the Invention]

[0009] According to the present invention, when the mounting portion of the case is inserted into the mounting hole of the elastic member, the inclined surface that abuts against one side of the mounting hole, the first temporary holding portion that abuts against the inner circumference of the other side of the mounting hole, and / or the second temporary holding portion that abuts against the peripheral edge of the other side of the mounting hole suppress the inclination of the elastic member relative to the mounting portion, thereby temporarily holding the elastic member relative to the mounting portion. As a result, the posture of the elastic member relative to the mounting portion can be maintained in a posture suitable for equipment that can automate the insertion of the mounting portion into the mounting hole, for example, thereby improving the workability of attaching the elastic member to the mounting portion of the case.

Embodiments for Carrying Out the Invention

[0011] (An Embodiment of the Locking Device for the Opening / Closing Body) Hereinafter, an embodiment of the locking device for the opening / closing body according to the present invention will be described with reference to the drawings.

[0012] As shown in Figures 18 and 19, the locking device 10 for the opening / closing body in this embodiment (hereinafter also simply referred to as "locking device 10") is used to lock in a closed position an opening / closing body 5, such as a glove box, which is attached to an opening 2 of a fixed body 1, such as the instrument panel of a vehicle, so as to be able to be opened and closed. In particular, the locking device 10 in this embodiment makes it possible to electrically open the opening / closing body 5, which is locked in a closed position to the opening 2 of the fixed body 1, using a motor 13 or the like. However, the locking device for the opening / closing body may be applied not only to a structure that opens the opening / closing body electrically, but also to a structure that opens it mechanically by the operator's manual power.

[0013] Referring to Figures 1-3, the locking device 10 of this embodiment mainly comprises a pair of locking parts 3, 3 provided in the opening 2 of the fixed body 1, a case 11 arranged on the opening / closing body 5 and having a mounting part 50, a rotating body 60 rotatably supported in the case 11, a torsion spring 12 that biases the rotating body 60 to rotate in a predetermined direction (also called the first direction; see arrow F1 in Figure 18), a pair of locking members 80, 81 that slide in conjunction with the rotation of the rotating body 60 and engage with and disengage from the locking parts 3, 3, and an elastic member 90 having a mounting hole 93 into which the mounting part 50 is inserted and which is attached to the mounting part 50. The case 11 consists of a first case 20 and a second case 40 assembled to the first case 20.

[0014] The torsion spring 12 constitutes the "biasing means" in this invention. The torsion spring 12 consists of a wound portion 12a formed by winding a wire, a first arm portion 12b protruding inward from one circumferential end of the wound portion 12a, and a second arm portion 12c protruding inward from the other circumferential end of the wound portion 12a. The "first direction" mentioned above refers to the direction in which the torsion spring 12, which is the biasing means, rotates the rotating body 60, as shown by arrow F1 in Figures 15 and 18.

[0015] Furthermore, the locking device 10 is equipped with a motor 13 having a rotating shaft 13a, and a worm 14 having teeth 14a on its outer circumference is connected to the rotating shaft 13a. The motor 13 rotates the worm 14 via the rotating shaft 13a, causing the rotating body 60 to rotate in the opposite direction to the rotational biasing direction of the torsion spring 12.

[0016] The case 11 described above houses the rotating body 60, the elastic member 90, and the motor 13 inside.

[0017] Furthermore, as described above, the locking device for the opening / closing body may be applied to, for example, a structure in which a box-shaped glove box is rotatably attached to the opening of the instrument panel (in this case, the instrument panel is the "fixed body" and the glove box is the "opening / closing body"), or to a structure in which a lid is rotatably attached to the opening of the instrument panel (in this case, the instrument panel is the "fixed body" and the lid is the "opening / closing body"), and can be widely used for various opening / closing bodies that open and close the opening of a fixed body.

[0018] Furthermore, as shown in Figures 18 and 19, in this embodiment, a pair of hole-shaped locking parts 3, 3 are provided on both sides in the width direction of the opening 2 of the fixed body 1. Note that the locking parts do not have to be hole-shaped; they may be concave, protruding, frame-shaped, etc. Also, the locking parts may be provided on the opening / closing body rather than the fixed body, and are not particularly limited.

[0019] Furthermore, as shown in Figure 1, a switch 7 (such as a touch switch, push button, or lever type switch) for operating the motor 13 is located at a predetermined position on the surface side of the opening / closing body 5.

[0020] The motor 13 is electrically connected to a power connector (not shown) via a pair of busbars 17, 17, and its rotation shaft 13a rotates when the switch 7 is operated.

[0021] As shown in Figure 1, each locking member 80, 81 is rod-shaped with a bent portion in the middle of its axial direction, and each is provided with an engaging portion 82 with a tapered surface at its axial end, and these engaging portions 82, 82 engage with and disengage from the pair of locking portions 3, 3. Note that the engaging portions 82 may be provided in the middle of the axial direction, rather than at the end of the locking members 80, 81.

[0022] Furthermore, in this embodiment, the locking members 80 and 81 are slidably arranged on the opening / closing body 5, and the locking portion 3 is formed on the opening 2 side of the fixed body 1. However, conversely, the locking members may be slidably arranged on the fixed body side, and the locking portion may be provided on the opening / closing body side.

[0023] Furthermore, as shown in Figure 18, the base ends 83, 83 of the pair of locking members 80, 81 are pivotally supported on the rotating body 60, and the engaging portion 82 at the tip is biased in the direction of engagement via the rotating body 60, which is rotationally biased by the torsion spring 12.

[0024] Next, we will describe in detail the first case 20, which constitutes case 11.

[0025] Furthermore, in this locking device 10, a support shaft is provided on either the first case 20 or the rotating body 60, and a support hole through which the support shaft is inserted is provided on the other. As shown in Figure 2, in this embodiment, the support shaft 32 is provided on the first case 20 side, and a support hole 65 (see Figure 3) is provided on the rotating body 60 side, but details will be described later.

[0026] Furthermore, as shown in Figure 10, a notch 67 is provided on the periphery of the support hole 65, and the support shaft 32 is provided with a protrusion (first protrusion 33 in this embodiment) that can pass through the notch 67. In addition, after the first protrusion 33 has passed through the notch 67, the rotating body 60 is rotated in a second direction opposite to the first direction (see arrow F2), and a retaining portion is provided to prevent the rotating body 60 from coming off the first case 20.

[0027] Furthermore, a first engagement surface and a second engagement surface are formed between the first case 20 and the rotating body 60, which engage and disengage from each other (engage and disengage from each other) as the rotating body 60 rotates. Moreover, the first engagement surface and the second engagement surface are configured to engage with each other, thereby restricting the rotational movement of the rotating body 60 in the first direction and temporarily fixing the rotating body 60 to the first case 20, forming a temporary fixing portion.

[0028] As shown in Figure 2, the first case 20 consists of a bottom wall 21 and a peripheral wall 22 erected from its periphery, and has a bottomed frame shape with an opening on the side facing the second case 40 (upper side).

[0029] Referring also to Figure 7, the first case 20 has a motor arrangement section 23 in which the motor 13 is arranged, and a gear arrangement section 24 provided adjacent to the motor arrangement section 23 on the side of the motor 13's rotation axis 13a, in which the worm 14 and the rotating body 60 are arranged. Furthermore, one side of the motor arrangement section 23 of the first case 20 is provided with a connector insertion section 25 into which a power connector (not shown) that supplies electricity to the motor 13 is inserted.

[0030] Furthermore, as shown in Figures 2 and 7, on the peripheral wall 22 on the gear arrangement portion 24 side, on the curved portion opposite to the worm 14 arrangement location, a groove-shaped elastic member arrangement recess 27 is formed in a predetermined range along the circumferential direction, extending to a predetermined depth from the end on the side facing the second case 40. A part of the elastic member 90 is housed and arranged in this elastic member arrangement recess 27.

[0031] Furthermore, as shown in Figure 2, a rib-shaped inner wall portion 28 is provided protruding from the end of the peripheral wall 22 of the first case 20 on the side facing the second case 40, surrounding the peripheral edge of the gear arrangement portion 24, excluding the elastic member arrangement recess 27, and the peripheral edge of the motor arrangement portion 23, excluding the connector insertion portion 25. In addition, a plurality of engaging protrusions 29 for assembly with the second case 40 are provided at predetermined locations on the outer circumference of the peripheral wall 22.

[0032] Furthermore, a pair of mounting flanges 30, 30 protrude from predetermined locations on the end of the peripheral wall 22 on the side facing the second case 40. A round hole 30a is formed in one of the mounting flanges 30, and an elongated hole 30b is formed in the other mounting flange 30. In addition, both mounting flanges 30, 30 have multiple mounting holes 30c for attachment to the opening / closing body 5.

[0033] Furthermore, as shown in Figure 2, a substantially cylindrical support shaft 32, which rotatably supports the rotating body 60, protrudes from the bottom wall 21 on the gear arrangement section 24 side. In this embodiment, the support shaft 32 protrudes integrally from the bottom wall 21 of the first case 20. In addition, a first convex portion 33 with a first engagement surface 33a is provided protruding from the outer circumference of the tip of the support shaft 32 in the direction of protrusion (see Figure 3).

[0034] Furthermore, a roughly C-shaped spring locking wall portion 34 is provided protruding from the outer circumference of the support shaft 32 of the bottom wall 21, with a notched groove-shaped spring locking groove 34a formed at one location in the circumferential direction. The first arm portion 12b of the torsion spring 12 is locked into the spring locking groove 34a of this spring locking wall portion 34 (see Figure 10). Also, a ring-shaped spring holding wall portion 35 is provided protruding from the outer circumference of the spring locking wall portion 34 of the bottom wall 21. As shown in Figure 10, the wound portion 12a of the torsion spring 12 is positioned and held inside this spring holding wall portion 35.

[0035] The shape and structure of each part (bottom wall, peripheral wall, engaging projection, engaging piece, mounting flange, notch, etc.) of the first case described above are not limited to the above-described embodiment.

[0036] Next, the rotating body 60 will be described in detail with reference to Figures 8A, 8B, etc.

[0037] As shown in Figures 2 and 8, the rotating body 60 of this embodiment has a gear section 61 which is a substantially cylindrical frame shape with an open bottom, consisting of a ceiling wall 61a and a substantially cylindrical peripheral wall 61b that is suspended from its periphery, and a rotating section 62 which is coaxially connected to the gear section 61 and has a smaller diameter than the gear section 61.

[0038] Furthermore, an O-shaped sealing ring 15 is attached to the outer circumference of the rotating part 62, which seals the gap between the opening 59 of the second case 40 and the rotating body 60.

[0039] Furthermore, a shaft hole 63 is formed through the radial center of the ceiling wall 61a of the rotating part 62 and the gear part 61. In addition, a substantially cylindrical cylindrical part 64 is provided protruding from the periphery of the shaft hole 63 on the back side of the ceiling wall 61a of the gear part 61.

[0040] Furthermore, a roughly C-shaped annular inner projection 66 protrudes from the inner circumferential surface of the cylindrical portion 64, with a notch 67 formed by cutting out a portion of the circumferential direction along the axial direction of the cylindrical portion 64 (see Figure 17). The first protrusion 33 provided on the support shaft 32 can be inserted through the notch 67.

[0041] Furthermore, the inner portion of the inner projection 66 of the cylindrical portion 64 and the inner portion of the shaft hole 63 form the support hole 65, and the support shaft 32 provided in the first case 20 is inserted into this support hole 65, thereby rotatably supporting the rotating body 60 relative to the first case 20.

[0042] In this embodiment, a support shaft 32 is provided on the first case 20 side, and a support hole 65 through which the support shaft 32 is inserted is provided on the rotating body 60 side, thereby rotatably supporting the rotating body 60 with respect to the first case 20. However, conversely, the support shaft may be provided on the rotating body side, and a support hole may be provided on the first case side, thereby rotatably supporting the rotating body with respect to the first case.

[0043] Furthermore, the inner diameter of the shaft hole 63 is formed to be larger than the outer diameter of the tip of the support shaft 32, including the first protrusion 33, so that the support shaft 32, including the first protrusion 33, can be received inside the shaft hole 63.

[0044] As shown in Figure 8(A), a pair of pivot portions 69, 69 with spherically shaped tips are provided protruding from the surface of the rotating portion 62 (the surface on the side of the opening 59 of the second case 40) at a location opposite to the rotation center of the rotating portion 62 (a position that coincides with the axis of the support shaft 32).

[0045] Then, a pair of pivot parts 69, 69 are inserted into the base ends 83, 83 of a pair of locking members 80, 81 in a way that prevents them from coming loose, and the base ends 83, 83 of the pair of locking members 80, 81 are pivotally supported at a point opposite to the rotation center of the rotating part 62. As a result, when the rotating body 60 rotates, the pair of locking members 80, 81 slide synchronously in opposite directions (see Figure 22).

[0046] Furthermore, as shown in Figure 8(B), a roughly fan-shaped locking portion 70 is provided protruding from the back side of the ceiling wall 61a of the gear portion 61. The narrow base end of this locking portion 70 is connected to the outer circumference of the cylindrical portion 64. In addition, the second arm portion 12c of the torsion spring 12, which is a biasing means, is locked to one side surface 70a of the locking portion 70 in the circumferential direction.

[0047] As described above, the first arm 12b of the torsion spring 12 is locked in a spring locking groove 34a provided in the first case 20, and the rotating body 60 is rotatably supported on the support shaft 32 with the first arm 12b and the second arm 12c separated. Therefore, the rotating body 60 is rotationally biased in the direction in which the second arm 12c of the torsion spring 12 approaches the first arm 12b, that is, in the direction of arrow F1 in Figures 15 and 18, so that the engaging portions 82, 82 of the pair of locking members 80, 81 are biased in the direction in which they engage with the locking portions 3, 3.

[0048] Furthermore, as shown in Figures 2 and 8, teeth 71 that mesh with the teeth 14a of the worm 14 are formed on the outer circumferential surface of the peripheral wall 61b of the gear portion 61 in a predetermined range along the circumferential direction. Therefore, as the worm 14 rotates via the motor 13, the rotating body 60, which has teeth 71 that mesh with the teeth 14a of the worm 14, rotates against the rotational biasing force of the torsion spring 12.

[0049] Furthermore, the rotating body 60 is provided with a projection on a part of its outer circumference. In this embodiment, as shown in Figure 15, when viewed from the axial direction of the rotating body 60, the first projection 72 protrudes from the outer surface of the peripheral wall 61b of the gear portion 61, at a position close to one end of the tooth 71 in the circumferential direction, and the second projection 74 protrudes from the outer surface of the same peripheral wall 61b, at a position close to the other end of the tooth 71 in the circumferential direction.

[0050] As shown in Figure 15, when the motor 13 is not operating and the worm 14 is not rotating, the second projection 74 of the rotating body 60, which is rotationally biased in the first direction (see arrow F1) by the rotational biasing force of the torsion spring 12, comes into contact with the contact portion 94 of the elastic member 90, which will be described later, thereby restricting the rotational position of the rotating body 60.

[0051] Furthermore, as shown in Figure 16, when the motor 13 operates and the worm 14 rotates, and the rotating body 60 rotates to its maximum extent in a second direction opposite to the first direction (see arrow F2 in Figure 15) against the rotational biasing force of the torsion spring 12, the first projection 72 of the rotating body 60 comes into contact with the stopper portion 92 of the elastic member 90, which will be described later, and the rotational position of the rotating body 60 is restricted.

[0052] Furthermore, as shown in Figure 8(A), a tapered surface 74b is formed on one circumferential end surface of the second protrusion 74 on the side of the first protrusion 72, and on one end in the thickness direction on the side of the ceiling wall 61a of the gear portion 61. This tapered surface 74b is the surface of the second case 40 that is pressed against the inclined surface 53 of the mounting portion 50, which will be described later.

[0053] Furthermore, as shown in Figures 8 and 15, a sliding contact portion 76 is provided on a part of the outer circumference of the rotating body 60, which slides against the elastic member 90 (in this case, slides against the stopper portion 92 of the elastic member 90) as the first projection 72 approaches the stopper portion 92 of the elastic member 90.

[0054] Furthermore, the inner diameter of the support hole 65 is smaller than the inner diameter of the shaft hole 63 and the outer diameter of the tip of the support shaft 32, including the first protrusion 33, and is an inner diameter that matches the outer diameter of the support shaft 32.

[0055] Then, the notch 67 of the rotating body 60 is aligned with the first protrusion 33 of the support shaft 32 (see Figure 10), the support shaft 32 is inserted from the lower end opening of the cylindrical portion 64, and the first protrusion 33 is inserted through the upper opening of the notch 67 (i.e., after the first protrusion 33 has passed through the notch 67), and the rotating body 60 is rotated against the rotational biasing force of the biasing means (torsion spring 12) in the second direction shown by arrow F2 in Figure 10 (opposite to the first direction shown by arrow F1), causing the first protrusion 33 to shift circumferentially relative to the notch 67, thereby preventing the rotating body 60 from coming off and allowing it to be held in place on the support shaft 32.

[0056] Furthermore, as shown in Figure 11, a second protrusion 68 with a second engagement surface 68a is provided on the periphery of the support hole 65. In this embodiment, the second protrusion 68 is provided projecting from a predetermined circumferential position on the inner circumferential surface of the shaft hole 63, which is located on the periphery of the support hole 65, from a position below it (on the side of the inner protrusion 66). The second protrusion 68 is positioned to move toward and away from the first protrusion 33 provided on the support shaft 32 side, and its second engagement surface 68a engages with (see Figure 11) or separates from (see Figure 3) the first engagement surface 33a of the first protrusion 33.

[0057] As mentioned above, the rotating body 60 is rotated in the first direction shown by arrow F1 in Figures 15 and 18 by the rotational biasing force of the torsion spring 12. At this time, the first engagement surface 33a of the first protrusion 33 and the second engagement surface 68a of the second protrusion 68 engage with each other, thereby restricting and temporarily fixing the rotation of the rotating body 60 against the rotational biasing force of the torsion spring 12 at this position.

[0058] The rotating body described above is not limited to the shape and structure described above, and is acceptable as long as it has a shape and structure that includes, at least, a support shaft, support hole, notch, protrusion, etc., between it and the first case.

[0059] Next, we will describe in detail the second case 40, which constitutes case 11.

[0060] Furthermore, between the second case 40 and the rotating body 60, there is a cam mechanism that rotates the rotating body 60 by a predetermined angle in the second direction so that the first engagement surface 33a and the second engagement surface 68a, which are engaged when the second case 40 is assembled to the first case 20, are separated. After the rotating body 60 has been rotated by the cam mechanism, a retaining part is provided that engages with the rotating body 60 to hold the rotating body 60 relative to the first case 20 with the first engagement surface 33a and the second engagement surface 68a separated. The "retaining part" refers to the elastic member 90, and the details of this elastic member 90 will be described later.

[0061] First, let me explain the second case 40. In this embodiment, the second case 40 consists of a ceiling wall 41 and a peripheral wall 42 suspended from its periphery, and is frame-shaped with an opening on the side facing the first case 20 (downward side).

[0062] As shown in Figures 2 and 3, the second case 40 is provided with a motor arrangement section 43, a gear arrangement section 44, and a connector insertion section 45, respectively, at positions corresponding to the motor arrangement section 23, gear arrangement section 24, and connector insertion section 25 of the first case 20.

[0063] Furthermore, multiple engaging pieces 47 are vertically positioned on the outer circumference of the peripheral wall 42 at locations corresponding to the multiple engaging projections 29 of the first case 20. By engaging these multiple engaging pieces 47 with the multiple engaging projections 29, the second case 40 is assembled to the first case 20, as shown in Figures 3 and 6(B), thereby forming the case 11.

[0064] Inside the case 11, the motor arrangement sections 23 and 43 provide space for the motor 13, the gear arrangement sections 24 and 44 provide space for the worm 14 and the rotating body 60, and the connector insertion sections 25 and 45 allow a power connector (not shown) to be inserted, and also provide connector insertion sections.

[0065] Furthermore, a cylindrical connector case 16, separate from case 11, is assembled to the connector insertion section. Inside this connector case 16, a pair of busbars 17, 17 and an O-ring 18 are arranged, and a power connector (not shown) for supplying electricity to the motor 13 is inserted.

[0066] Furthermore, a pair of mounting flanges 48, 48 protrude from the end of the peripheral wall 42 on the side facing the first case 20, at a position corresponding to the pair of mounting flanges 30, 30 of the first case 20. As shown in Figure 4, a positioning pin 48a protrudes from the inner surface of each mounting flange 48.

[0067] When assembling the second case 40 to the first case 20, one positioning pin 48a is fitted into the round hole 30a, and the other positioning pin 48a is inserted into the elongated hole 30b in a swivel manner, thereby correcting any dimensional errors between the two cases 20 and 40 as appropriate during assembly. Also, as shown in Figure 2, both mounting flanges 48, 48 each have multiple mounting holes 48b formed therein for attachment to the opening / closing body 5.

[0068] Furthermore, as shown in Figure 2, a mounting portion 50 for attaching the elastic member 90 to the second case 40 protrudes from the ceiling wall 41 at a position that aligns with the elastic member placement recess 27 provided in the first case 20, and from the inside of the curved portion of the peripheral wall 42 on the gear placement portion 44 side, opposite to the location where the worm 14 is placed.

[0069] Furthermore, on one side of the mounting portion 50, the mounting portion 50 gradually narrows towards the tip in the insertion direction S of the mounting portion 50 into the mounting hole 93 (see Figure 9) of the elastic member 90, and as shown in Figure 12A, a slope 53 is formed that abuts against one side 93c of the mounting hole 93 when the mounting portion 50 is inserted into the mounting hole 93. Note that the insertion direction S of the mounting portion 50 into the mounting hole 93 of the elastic member 90 will also be simply referred to as the "mounting portion insertion direction S" in the following description.

[0070] Furthermore, the other side of the mounting portion 50 is provided with a first temporary holding portion 55, which is formed substantially parallel to the mounting portion insertion direction S, and which temporarily holds the elastic member 90 by contacting the inner circumference of the other side 93d of the mounting hole 93 when the mounting portion 50 is inserted into the mounting hole 93 and the inclined surface 53 is in contact with one side 93c of the mounting hole 93; and a second temporary holding portion 56, which is formed in a stepped shape, and which temporarily holds the elastic member 90 by contacting the back side of the elastic member 90 and the peripheral edge of the other side 93d of the mounting hole 93 when the mounting portion 50 is inserted into the mounting hole 93 and the inclined surface 53 is in contact with one side 93c of the mounting hole 93.

[0071] Referring together to Figures 4, 5, 12A, and 12B, the mounting portion 50 in this embodiment has a base portion 51 erected from the inner surface of the ceiling wall 41 of the second case 40, and a tip portion 52 connected to the tip of the base portion 51 in the direction of erection, and is in the shape of a projection extending in the circumferential direction of the peripheral wall 42.

[0072] Furthermore, on one side in the width direction of the tip portion 52 of the mounting portion 50, a slope 53 is formed, which is inclined at a predetermined angle so as to gradually narrow the tip portion 52 toward the tip (end facing the insertion direction S) of the mounting portion 50 into the mounting hole 93. When the mounting portion 50 is inserted into the mounting hole 93, this slope 53 abuts against one side portion 93c of the mounting hole 93, specifically, against the base end of the inner circumference of one side portion 93c of the mounting hole 93 and the back side of the elastic member 90, which is the periphery of one side portion 93c of the mounting hole 93.

[0073] Furthermore, on one side of the tip portion 52 in the width direction, opposite to the inclined surface 53, a locking step portion 54 is formed, which is perpendicular to one side of the base portion 51 in the width direction. As shown in Figure 12B, this locking step portion 54 is on the front side of the elastic member 90 (opposite to the ceiling wall 41 of the second case 40) and locks onto the periphery of one side portion 93c of the mounting hole 93, thereby attaching (permanently fixing) the elastic member 90 to the mounting portion 50.

[0074] On the other side of the tip 52 of the mounting portion 50 in the width direction, there is a first temporary holding portion 55 that extends linearly parallel to the mounting portion insertion direction S, and a second temporary holding portion 56 that is formed in a stepped shape, extending from the base end 55a of the first temporary holding portion 55 via a first R-shaped portion 56a that has a concave curved surface.

[0075] Furthermore, a second R-shaped portion 56b, which has a convex curved R shape, is provided on the outer side in the width direction of the second temporary holding portion 56, spaced apart from the inclined surface 53. In other words, the second temporary holding portion 56 in this embodiment is stepped in shape and has two R-shaped portions 56a and 56b. Note that the second temporary holding portion 56 in this embodiment is formed to be approximately parallel to a line segment L (see Figure 5) that is perpendicular to the mounting portion insertion direction S.

[0076] Then, as shown in Figure 12A, with the mounting portion 50 inserted into the mounting hole 93 of the elastic member 90 (hereinafter also simply referred to as the "mounting portion insertion state"), the inclined surface 53 abuts against one side 93c of the mounting hole 93, and in the said mounting portion insertion state, the first temporary holding portion 55 abuts against the inner circumference of the other side 93d of the mounting hole 93, and the second temporary holding portion 56 abuts against the back side of the elastic member 90 and the periphery of the other side 93d of the mounting hole 93, thereby temporarily holding the elastic member 90 in a predetermined position relative to the mounting portion 50.

[0077] Furthermore, as shown in Figure 12A, when the elastic member 90 is pushed against the mounting portion 50 from a state in which the elastic member 90 is temporarily held in place by the mounting portion 50 (pushed in a direction that brings the elastic member 90 closer to the ceiling wall 41 of the second case 40), the inclined surface 53 of the mounting portion 50 presses against the inner circumference of one side portion 93c of the mounting hole 93, expanding the elastic member 90, and the mounting portion 50 is gradually inserted into the mounting hole 93. At the same time, the stepped second temporary holding portion 56 of the mounting portion 50 enters into the mounting hole 93.

[0078] Subsequently, as the locking step portion 54 of the mounting portion 50 disengages from the front opening of the mounting hole 93c on the front side of the elastic member 90, and the second temporary holding portion 56 disengages from the front opening of the mounting hole 93d on the other side of the elastic member 90, the expanded elastic member 90 elastically returns to its original position, and as shown in Figure 12B, the back side of the elastic member 90 comes into contact with the inner surface of the ceiling wall 41 of the second case 40, and the locking step portion 54 of the mounting portion 50 engages with the periphery of the mounting hole 93c on the front side of the elastic member 90.

[0079] As a result, as shown in Figure 13, the elastic member 90 is permanently fixed to the mounting portion 50 so that it does not come off from the axial direction of the mounting portion 50.

[0080] In this embodiment, the first temporary holding portion 55 is formed in a straight line parallel to the mounting portion insertion direction S. However, the first temporary holding portion does not need to be substantially parallel to the mounting portion insertion direction S (it may be inclined at a predetermined angle with respect to the mounting portion insertion direction S), and it is sufficient that it can temporarily hold the elastic member by contacting the inner circumference of the other side of the mounting hole when the mounting portion is inserted.

[0081] Furthermore, in this embodiment, both the first temporary holding portion 55 and the second temporary holding portion 56 are provided on the other side of the mounting portion 50, but either the first temporary holding portion or the second temporary holding portion may be provided on the other side of the mounting portion. Moreover, the other side of the mounting portion may be provided with the first temporary holding portion and a slope, or with the second temporary holding portion and a slope.

[0082] Figure 20A shows a first modified example of the other side of the mounting portion. In this first modified example, only a first temporary holding portion 55, which is formed substantially parallel to the mounting portion insertion direction S, is provided on the other side of the mounting portion 50A. In this first modified example, when the mounting portion is inserted, the inclined surface 53 abuts against one side 93c of the mounting hole 93, and the first temporary holding portion 55 abuts against the inner circumference of the other side 93d of the mounting hole 93, thereby temporarily holding the elastic member 90 with respect to the mounting portion 50A.

[0083] Furthermore, the other side of the mounting portion may be provided with a first temporary holding portion 55 and a slope 57 as shown by the dashed line in Figure 20A.

[0084] Figure 20B shows a second modified example of the other side of the mounting portion. In this second modified example, the other side of the mounting portion 50B is provided with a stepped second temporary holding portion 56 and a sloped surface 57 that gradually narrows towards the tip portion 52 in the direction of insertion S of the mounting portion. In this second modified example, when the mounting portion is inserted, the sloped surface 53 abuts against one side 93c of the mounting hole 93, and the second temporary holding portion 56 abuts against the back side of the elastic member 90 and the periphery of the other side 93d of the mounting hole 93, thereby temporarily holding the elastic member 90 with respect to the mounting portion 50B.

[0085] Furthermore, the inclined surface 53 provided on one side of the mounting portion 50 and the tapered surface 74b provided on the second protruding portion 74 of the rotating body 60 described above constitute the "cam mechanism".

[0086] In other words, as described above, the notch 67 of the rotating body 60 is aligned with the first protrusion 33 of the support shaft 32 (see Figure 10), the support shaft 32 is inserted from the lower end opening of the cylindrical portion 64, and after the first protrusion 33 passes through the notch 67, the rotating body 60 is rotated in the second direction shown by arrow F2 in Figure 10 against the rotational biasing force of the torsion spring 12, so that the first protrusion 33 is positioned circumferentially with respect to the notch 67, thereby preventing the rotating body 60 from coming off the support shaft 32 and holding it in place. At the same time, as shown in Figure 11, the protrusions 33 and 68 are made to overcome each other against the rotational biasing force of the torsion spring 12, and the two engaging surfaces 33a and 68a are engaged with each other, thereby temporarily fixing the rotating body 60 so that it does not rotate any further toward the first direction.

[0087] After the temporary fastening described above, the second case 40, with the elastic member 90 attached to the mounting portion 50, is pushed toward the first case 20. Then, as shown in Figure 14(A), the inclined surface 53 of the mounting portion 50 presses against the tapered surface 74b of the second projection 74 of the rotating body 60, causing the second engaging surface 68a of the second convex portion 68 to rotate away from the first engaging surface 33a of the first convex portion 33, against the rotational biasing force of the torsion spring 12.

[0088] Subsequently, as the second case 40 is pushed in further, the inclined surface 53 of the mounting portion 50 further presses against the tapered surface 74b of the second projection 74 of the rotating body 60, as shown in Figure 14(B). This causes the second engagement surface 68a of the second protrusion 68 to rotate further away from the first engagement surface 33a of the first protrusion 33, against the rotational biasing force of the torsion spring 12.

[0089] From the above state, the second case 40 is further pushed in, and the multiple engaging pieces 47 of the second case 40 are engaged with the multiple engaging protrusions 29 of the first case 20, thereby assembling the second case 40 to the first case 20. At this point, the base 91 of the elastic member 90 attached to the mounting portion 50 of the second case 40 engages with the second projection 74 of the rotating body 60. As a result, as shown in Figures 3 and 15, the rotating body 60 is held in place by the elastic member 90 with the first engaging surface 33a and the second engaging surface 68a separated from each other, relative to the first case 20.

[0090] Furthermore, as shown in Figures 4 and 5, multiple ribs 51a are provided protruding from the outer surface of the base end of the mounting portion 50 at predetermined intervals. These multiple ribs 51a are positioned to abut against the inner surface 93a of the enlarged diameter portion of the mounting hole 93 of the elastic member 90 (see Figure 9(B)).

[0091] Furthermore, a notch 58 is formed on the outer circumference of the case, at a position opposite to the mounting portion 50 for attaching the elastic member 90. In this embodiment, the notch 58 is formed in an arc shape along the peripheral wall 42 of the second case 40, on the side of the gear arrangement portion 44, at a position opposite to the mounting portion 50, on the curved portion opposite to the worm 14 arrangement location.

[0092] As shown in Figures 5(B) and 13, the peripheral wall on the gear arrangement section 44 side, with one circumferential end of the notch 58 forming a wall portion 42a positioned opposite the outer circumference of the rotating body 60. Also, as shown in Figure 2, a circular opening 59 is formed in the ceiling wall 41 on the gear arrangement section 44 side, allowing the rotating portion 62 of the rotating body 60 to protrude.

[0093] The shape, structure, layout, etc., of each part (bottom wall, peripheral wall, engaging projection, engaging piece, mounting flange, mounting part, slope of mounting part, first temporary holding part, second temporary holding part, etc.) of the second case described above are not limited to the above-described embodiment.

[0094] On the other hand, as shown in Figure 9, the elastic member 90 forming the "main stopper" is made of a predetermined elastic material and has cushioning properties, and has a base portion 91 that is attached to and supported by a mounting portion 50 provided on the case 11, and a stopper portion 92 that abuts against the first protrusion 72 of the rotating body 60 and restricts the maximum rotational position of the rotating body 60 in a predetermined direction.

[0095] As described above, the elastic member 90 engages with the rotating body 60 after the rotating body 60 has been rotated by the cam mechanism (in this case, the inclined surface 53 of the mounting portion 50 and the tapered surface 74b of the rotating body 60), and holds the rotating body 60 relative to the first case 20 with the first engagement surface 33a and the second engagement surface 68a separated.

[0096] In this embodiment, the elastic member 90 has a thick block shape that extends for a predetermined length and is formed with a predetermined thickness so as to be curved overall, so as to fit the curved peripheral walls 22, 42 on the gear arrangement side of the first case 20 and second case 40 that constitute the case 11.

[0097] The base portion 91 has curved surfaces on both sides 91a and 91b along its longitudinal direction. One side 91a is a surface positioned opposite to the inner side of the peripheral walls 22 and 42 of both cases 20 and 40 on the gear arrangement side. The other side 91b is a surface positioned opposite to the outer side of the peripheral wall 61b of the gear portion 61 of the rotating body 60.

[0098] Furthermore, a mounting hole 93 is formed inside the base portion 91, into which the mounting portion 50 is inserted, and into which the elastic member 90 is attached. This mounting hole 93 extends along the longitudinal direction of the base portion 91, and is an elongated hole with curved inner surfaces 93a and 93b along the longitudinal direction. In addition, one side portion 93c and the other side portion 93d are provided at both ends of the mounting hole 93 in the longitudinal direction.

[0099] Furthermore, the other end of the base 91 in the longitudinal direction forms a contact portion 94, and when the motor 13 is not operating and the worm 14 is not rotating, the second projection 74 of the rotating body 60, which is rotationally biased by the torsion spring 12, comes into contact with this contact portion 94 (see Figure 15).

[0100] Furthermore, on one side surface 91a of the base 91, in a predetermined range from the ceiling-side end face of the base 91 to the bottom side, a protruding wall portion 95 extends into the notch 58 of the second case 40 and closes the notch 58.

[0101] Then, with the second case 40 assembled to the first case 20, the elastic member 90 attached to the mounting portion 50 is positioned such that the portion of the base 91 below the protruding wall portion 95 is housed in the elastic member placement recess 27 of the first case 20, and the lower end of the protruding wall portion 95 is locked to the upper end of the peripheral wall 22 of the first case 20, which is provided with the elastic member placement recess 27 (see Figures 6(A) and 17).

[0102] Furthermore, in the above state, the upper end of the protruding wall portion 95 is locked to the upper end of the notch portion 58 of the second case 40, and both circumferential ends of the protruding wall portion 95 are locked to both circumferential ends of the notch portion 58, respectively, so that the notch portion 58 is closed.

[0103] Furthermore, as shown in Figure 9, an extension portion 96, which is narrower in width than the base portion 91 and has a plate-like shape, extends from the other longitudinal end of the base portion 91, closer to one side surface 91a. As shown in Figure 15, this extension portion 96 is positioned opposite the other circumferential end of the elastic member arrangement recess 27 on the gear arrangement portion 24 side of the first case 20, when the base portion 91 is housed in the elastic member arrangement recess 27.

[0104] On the other hand, the stopper portion 92 extends from one end of the base portion 91 in the longitudinal direction. In this embodiment, the stopper portion 92 has a substantially semicircular deformation hole 92a formed on its inner side, and an arch-shaped deformation wall portion 92b formed through the deformation hole 92a. Furthermore, the stopper portion 92 has a bulging portion 92d that bulges outward toward the outer surface of the rotating body 60 from the surface of the base portion 91 that faces the outer circumference of the rotating body 60 (the other side surface 91b).

[0105] As the elastic material forming the elastic member 90 described above, for example, rubber materials such as butyl rubber (isobutylene-isoprene rubber: IIR), nitrile rubber (NBR), ethylene propylene rubber (EPM, EPDM), butadiene rubber (BR), urethane rubber, silicone rubber, fluororubber, and acrylic rubber, as well as thermoplastic elastic elastomers, can be preferably used. In particular, it is preferable to use an elastic material with low rebound elasticity (high shock absorption capacity).

[0106] As the rotating body 60 rotates against the rotational biasing force of the torsion spring 12, and the first protrusion 72 comes into contact with the stopper portion 92 to restrict the maximum rotational position, the bulging portion 92d of the stopper portion 92 slides against the sliding contact portion 76 of the rotating body 60, and is damped by the rotational speed of the rotating body 60. Subsequently, the deformable wall portion 92b of the stopper portion 92 bends and deforms, coming into contact with the first protrusion 72, thereby reducing the impact noise (collision sound) when the first protrusion 72 of the rotating body 60 collides with the elastic member 90.

[0107] Furthermore, all parts constituting the elastic member 90 (base portion 91, stopper portion 92, protruding wall portion 95, extension portion 96, etc.) are integrally formed.

[0108] The elastic member described above is not limited to the shape and structure described above, and any shape and structure that can hold the rotating body in a state where the first engagement surface and the second engagement surface are separated is acceptable.

[0109] (Effects and Benefits) Next, the effects and benefits of the locking device 10 having the above structure will be explained.

[0110] In other words, when the opening / closing body 5 is pushed into the opening 2 of the fixed body 1 in order to close the opening 2, the tapered surfaces of the engaging portions 82, 82 of the pair of locking members 80, 81 are pressed against the inner surfaces on both sides of the opening 2, and the pair of locking members 80, 81 are pulled inward into the opening / closing body 5 against the biasing force of the torsion spring 12. When each engaging portion 82, 82 reaches the locking portion 3, 3, the rotating body 60 is rotated by the biasing force of the torsion spring 12, pushing the locking members 80, 81 outward from the opening / closing body 5, and each engaging portion 82, 82 engages with the locking portion 3, 3 respectively, thereby locking the opening 2 of the fixed body 1 in a closed state with the opening / closing body 5 (see Figures 1 and 18).

[0111] On the other hand, to open the opening / closing body 5 from the opening 2 of the fixed body 1, the switch 7 on the surface side of the opening / closing body 5 is operated. Then, electricity is supplied to the motor 13 through the busbars 17, 17 from a power connector connected to a power supply (not shown), causing the rotation shaft 13a of the motor 13 to rotate and the worm 14 to rotate. In conjunction with this, the rotating body 60 rotates in the second direction shown by arrow F2 in Figure 15, against the rotational biasing force of the torsion spring 12. As a result, the engaging portions 82, 82 of the pair of locking members 80, 81 slide in a direction away from the locking portions 3, 3, and the engagement between the engaging portion 82 and the locking portion 3 is released, so the opening / closing body 5 can be moved from the opening 2 of the fixed body 1 and the opening 2 of the fixed body 1 can be opened (see Figures 1 and 19).

[0112] In this locking device 10, the elastic member 90 is attached to the mounting portion 50 of the case 11 in the following manner.

[0113] First, the mounting portion 50 is inserted into the mounting hole 93 from the back side of the elastic member 90, starting from the tip portion 52 side. As shown in Figure 12A, the inclined surface 53 of the mounting portion 50 comes into contact with one side 93c of the mounting hole 93, the first temporary holding portion 55 comes into contact with the inner circumference of the other side 93d of the mounting hole 93, and the second temporary holding portion 56 comes into contact with the back side of the elastic member 90, which is the periphery of the other side 93d of the mounting hole 93. As a result, the elastic member 90 can be temporarily held in a predetermined position relative to the mounting portion 50.

[0114] From this state, by pushing the elastic member 90 against the mounting portion 50, as shown in Figure 12B, the back side of the elastic member 90 comes into contact with the inner surface of the ceiling wall 41 of the second case 40, and the locking step portion 54 of the mounting portion 50 engages with the front side of the elastic member 90, which is the peripheral edge of one side portion 93c of the mounting hole 93. As a result, the elastic member 90 can be permanently attached to the mounting portion 50.

[0115] As described above, in this locking device 10, when the mounting portion 50 is inserted into the mounting hole 93 of the elastic member 90, the inclined surface 53 that abuts against one side 93c of the mounting hole 93, the first temporary holding portion 55 that abuts against the inner circumference of the other side 93d of the mounting hole 93, and / or the second temporary holding portion 56 that abuts against the periphery of the other side 93d of the mounting hole 93 suppress the inclination of the elastic member 90 relative to the mounting portion 50, and the elastic member 90 can be temporarily held in place with respect to the mounting portion 50.

[0116] As a result, the position of the elastic member 90 relative to the mounting portion 50 can be maintained in a position suitable for equipment that can automate the insertion of the mounting portion 50 into the mounting hole 93, for example, thereby improving the workability of attaching the elastic member 90 to the mounting portion 50 of the case 11.

[0117] It should be noted that the present invention is not limited to the embodiments described above, and various modified embodiments are possible within the scope of the gist of the present invention, and such embodiments are also included in the scope of the present invention.
