Description

Locking device for opening and closing body

[0001] The present invention relates to a locking device for an opening / closing body, which is attached to an opening of a fixed body so as to be able to open and close the opening, for locking the opening / closing body in a closed state.

[0002] For example, an opening formed in a fixed body such as a console box of an automobile is provided with an opening / closing body such as a lid that can be opened and closed. A locking device is often provided between the opening and the opening / closing body, which locks the opening / closing body when it is closed and unlocks the opening / closing body when it is opened.

[0003] The following Patent Document 1 describes a locking device that is attached to an opening / closing body that is provided to be able to open and close an opening of a fixed body, and that includes a base member, a pair of locking bar members slidably supported on the base member, and a drive member that slides the pair of locking bar members in response to a user's operation. A rotatable operating member is attached to the tip end side of the base member, and a pair of spring members that are separate from the drive member are interposed between the base end of the drive member and a spring support portion on the base end side of the base member.

[0004] WO2022 / 004532A1

[0005] The locking device of Patent Document 1 is composed of components such as a base member, a pair of lock bar members, a drive member, an operating member, and a pair of spring members, which results in a complex structure with a large number of parts. In addition, the operating member and the pair of lock bar members must be assembled via the base member, making the assembly process cumbersome.

[0006] Therefore, an object of the present invention is to provide a locking device for an opening / closing body that can reduce the number of parts to simplify the structure and improve the ease of attaching an operating member to a locking member.

[0007] In order to achieve the above object, the present invention provides a locking device for an opening / closing body that locks an opening / closing body that is attached to an opening of a fixed body in an openable / closable manner in a closed state relative to the opening, the locking device comprising: a locking portion provided on one of the fixed body or the opening / closing body; a locking member that is arranged on the other of the fixed body or the opening / closing body and has a locking protrusion that slides to engage and disengage with the locking portion; and an operating member that is rotatably attached to the locking member and has a pressing portion, the locking member having an operating portion that slides in a direction in which the locking protrusion engages and disengages with the locking portion in conjunction with the operating member, and a pressing portion that is pressed by the pressing portion in accordance with the rotational movement of the operating member. and a groove portion extending in a direction in which the pressed portion moves when the pressed portion is pressed by the pressing portion, and the operating member has an operating portion that rotates in the pressing direction in which the pressing portion presses the pressed portion, the pressing portion connected to the operating portion, a rotation support portion that rotatably supports the operating member on the other of the fixed body or the opening / closing body, and a shaft portion that is inserted into the groove portion to allow rotation of the operating member before and after the locking member and the operating member are attached to the other of the fixed body or the opening / closing body, and that rotatably attaches the operating member to the locking member.

[0008] According to the present invention, since the operating member has a shaft in addition to the rotation support portion, the operating member can be rotatably attached to the locking member by the simple operation of inserting the shaft into the groove of the locking member. As a result, in a locking device for an opening / closing body having a rotatable operating member, it is possible to reduce the number of parts and improve the ease of attaching the operating member to the locking member.

[0010] (One embodiment of a locking device for an opening / closing body) Hereinafter, one embodiment of a locking device for an opening / closing body according to the present invention will be described with reference to the drawings.

[0011] 19 and 20, a locking device 10 for an opening / closing body (hereinafter referred to as "locking device 10") in this embodiment locks an opening / closing body 20, such as a lid attached to an opening 3 of a fixed body 1, such as a console box of a vehicle, in a closed state relative to the opening 3 of the fixed body 1, and opens the opening / closing body in the locked state. Note that the opening / closing body 20 has an elongated shape that extends to a predetermined length, but for convenience, only the tip end (one end) side in the extending direction is shown in Figures 1, 8 to 10, 15, and 16.

[0012] As shown in Figures 1, 15, 19, etc., the locking device 10 of this embodiment is mainly composed of a pair of locking portions 5, 5 (see Figure 19) provided on the fixed body 1, a locking member 40 that is disposed on the opening / closing body 20 and has a pair of locking protrusions 65, 65 that engage and disengage with the pair of locking portions 5, 5, an operating member 70 that is rotatably attached to the locking member 40 and has a pressing portion 77, and a pair of guide members 90, 90 that guide the sliding movement of the pair of locking protrusions 65, 65.

[0013] The pair of locking protrusions 65, 65 slide in a direction intersecting the extension direction of the opening / closing body 20 to engage with and disengage from the pair of locking portions 5, 5. As shown in Figures 1 and 19, the sliding direction of the pair of locking protrusions 65, 65 is referred to as "sliding direction F1."

[0014] 19 and 20 , a cylindrical protrusion 25 having an internal space R protrudes from the opening / closing body 20. Furthermore, the cylindrical protrusion 25 and the guide member 90 are formed with insertion holes 30 and 95 that communicate with the internal space R and allow the locking protrusion 65 to be inserted and removed.

[0015] 3 and 4, the locking member 40 has an operating portion 41 that slides the locking protrusion 65 in the direction of engaging and disengaging with the locking portion 5 in conjunction with the operating member 70, a pressed portion 50 that is pressed by the pressing portion 77 as the operating member 70 rotates, a groove portion 55 that extends in a pressed portion movement direction F3 (described below) in which the pressed portion 50 moves when the pressed portion 50 is pressed by the pressing portion 77, a pair of legs 60 that extend in a direction intersecting the sliding direction F1 of the locking protrusion 65 and are inserted into the internal space R, and a pair of locking protrusions 65 that protrude from the pair of legs 60 in the sliding direction F1.

[0016] 12 and 18, the pressing direction of the pressing portion 77 against the pressed portion 50 is referred to as the "pressing direction F2." When the operating member 70 presses the pressed portion 50, it rotates around the rotation support portion (the rotation support protrusion 33 and the rotation support hole 75) shown in Fig. 13 as the rotation center, and therefore the pressing direction F2 of the pressing portion 77 is a direction that describes a rotation locus centered around the rotation center C1 (see Fig. 13) of the rotation support portion (see Figs. 12 and 18).

[0017] Furthermore, when the operating member 70 rotates as shown in Figure 12 and the pressed portion 50 of the locking member 40 is pressed by the pressing portion 77 of the operating member 70 in the pressing direction F2 in Figure 12, the direction in which the pressed portion 50 moves is defined as the "pressed portion moving direction F3."

[0018] The operating member 70 also has an operating portion 72 that rotates in a pressing direction F2 in which the pressing portion 77 presses the pressed portion 50, the pressing portion 77 connected to the operating portion 72, a rotation support portion (rotation support hole 75) that rotatably supports the operating member 70 on the opening / closing body 20, and an axis portion 82 that is inserted into the groove portion 55 to allow rotation of the operating member 70 before and after the locking member 40 and the operating member 70 are attached to the opening / closing body 20, and that rotatably attaches the operating member 70 to the locking member 40.

[0019] In the following description, unless otherwise specified, the "width direction" of each component means the direction along the rotation center C1 of the rotation support part or the direction along the axis C2 of the shaft part 82 of the operating member 70 (see Figure 5, etc.) (excluding the guide member 90).

[0020] As shown in Figure 19, a fixed body 1 such as a console box has stepped portions 4 formed on both widthwise sides of an opening 3 to support both widthwise sides of an opening / closing body 20, and a pair of locking portions 5, 5 are formed closer to the bottom of the fixed body 1 than these stepped portions 4.

[0021] The opening / closing body 20 in this embodiment is made up of a base portion 21 that is open at the top, and a cover portion (not shown) that covers the upper opening of the base portion 12 .

[0022] The base portion 21 has a bottom wall 22 in the shape of a substantially long plate extending a predetermined length in one direction, and a peripheral wall 23 erected from the periphery of the bottom wall 22, and forms a bottomed frame shape with an open top. Note that a base end (other end) of the opening / closing body 20 in the extending direction (not shown) is rotatably supported by the opening 3 of the fixed body 1 to open and close the opening 3 of the fixed body 1.

[0023] In addition, a pair of openings 24, 24 having an approximately rectangular hole shape are formed at the tip (one end) of the base portion 21 in the extension direction, on both sides of the base portion 21 in the width direction (direction perpendicular to the extension direction).

[0024] Furthermore, cylindrical protrusions 25, 25 protrude from the rear (outer) peripheral edges of the pair of openings 24, 24. Each cylindrical protrusion 25 has a plurality of walls and is a substantially square tube with a bottom having an internal space R inside. A corresponding guide member 90 is housed and disposed in the internal space R of each cylindrical protrusion 25.

[0025] The above-mentioned "back side" or "rear side" refers to the side or surface located in the direction in which the opening / closing body 20 closes relative to the opening 3 of the fixed body 1. On the other hand, the "front side" or "front surface side" refers to the side opposite to the "back side" or "rear surface side," i.e., the side or surface located in the direction in which the opening / closing body 20 opens from the opening 3 of the fixed body 1. When the fixed body is provided in a vehicle, the side facing the interior space of the vehicle may be referred to as the "front side" or "front surface side," and the opposite side may be referred to as the "back side" or "rear surface side."

[0026] Furthermore, the above terms "front side," "surface side," "back side," and "rear side" have the same meanings for other members (locking members, operating members, guide members, etc.) described below.

[0027] 19 and 20, an engagement rib 26 extending along the protruding direction of the cylindrical protruding portion 25 is formed on the inner surface (the surface facing the internal space R) of the wall portion 25a of each cylindrical protruding portion 25 that is disposed opposite the mating cylindrical protruding portion 25. The engagement rib 26 is formed with an engagement groove 26a that engages with the second elastic engagement portion 97 (see FIG. 7) of the guide member 90.

[0028] In addition, the wall portion 25b of each cylindrical protrusion 25 is positioned away from the opposing cylindrical protrusion 25, and at a position close to the bottom, an insertion hole 30 having an approximately square hole shape is formed to allow the locking protrusion 65 to be inserted and removed.

[0029] 1, 15, and 16, a plurality of ribs 27 are formed on the inner surface of the bottom wall 22 of the base portion 21, on the outer (inner) periphery of each opening 24. Of these ribs, the inner surface of the rib 27a disposed close to the peripheral wall 23, facing the opening 24, is an inclined surface whose protrusion gradually decreases toward the opening 24 (see FIG. 1).

[0030] When the legs 60, 60 together with the guide members 90, 90 are inserted into the internal space R of the pair of cylindrical protrusions 25, 25 (see Figure 8), the rib 27a presses against the inclined portion 68 (see Figure 3) of the locking protrusion 65, causing the pair of locking protrusions 65, 65 to slide toward each other.

[0031] As shown in Figure 15, the opening / closing body 20 has regulating portions 28, 28 that receive the side portions of a pair of locking protrusions 65, 65 when the operating member 70 is rotated and the pressing portion 77 presses the pressed portion 50, thereby regulating the movement of the locking protrusions 65 in the pressed portion movement direction F3.

[0032] 1, a recess 22a is provided in the center of the width direction of the bottom wall 22. Furthermore, an inclined portion 22b is provided on the bottom wall 22 from a position adjacent to the recess 22a, which gradually slopes toward the upper opening of the base portion 21. A substantially rectangular operation opening 31 extending elongately in the width direction of the bottom wall 22 is formed in the inclined portion 22b of the bottom wall 22.

[0033] An operating portion 72 (see FIG. 5) of the operating member 70 can appear and disappear from this operating opening 31, that is, the amount of protrusion of the operating portion 72 from the operating opening 31 can be increased or decreased (see FIGS. 12 and 18).

[0034] As shown in Figure 1, a pair of ribs 32, 32 extend parallel to each other from both widthwise edges of the inclined portion 22b on both sides of the operation opening 31 toward the base end of the base portion 21 in the extension direction.

[0035] Each rib 32 is provided with a rotation support portion that rotationally supports the operating member 70. In this embodiment, a rotation support protrusion 33 having a substantially circular projection shape is provided on the inner surface side (the surface facing the mating rib 32) of the tip end of each rib 32 in the extension direction, and each rotation support protrusion 33 forms a rotation support portion on the opening / closing body 20 side. Each rotation support protrusion 33 is inserted into a rotation support hole 75, which is a rotation support portion on the operating member 70 side, thereby rotatably supporting the operating member 70. As shown in Figures 13 and 14, the pair of rotation support protrusions 33, 33 are arranged coaxially.

[0036] Each rotation support protrusion 33 has an inclined surface 33a formed on a portion thereof facing the operation opening 31 (see FIG. 14). Furthermore, a pair of elastic force imparting portions 34, 34 having a generally inverted L shape are provided on both widthwise sides of the recess 22a of the bottom wall 22.

[0037] A pair of support ribs 35, 35 having protruding stripes extend parallel to each other on the base end side of the recess 22a of the bottom wall 22 in the extension direction of the opening / closing body 20. The pair of support ribs 35, 35 abut against the back side of the first frame 45 of the locking member 40, etc., to support the locking member 40.

[0038] Next, a detailed description will be given of the locking member 40. As described above, the locking member 40 has the operating portion 41, the pressed portion 50, and the groove portion 55, but the operating portion 41 also has a pair of annular portions 42, 42 and a pair of connecting portions 43, 44 that connect the pair of annular portions 42, 42 together.

[0039] As shown in Figures 1, 3, and 15, each annular portion 42 is formed in a ring shape by connecting a pair of first frames 45, 45, a pair of second frames 46, 46, and a pair of third frames 47, 47, each of which is elastically deformable.

[0040] 15 , the pair of first frames 45 are disposed on both sides of the extending portion 51 and extend in the opposite direction to the pressed portion movement direction F3. The pair of second frames 46 extend in directions away from each other from the distal ends of the pair of first frames 45 in the extending direction. Furthermore, the pair of third frames 47 have portions 47 a that extend obliquely from the distal ends of the pair of second frames 46 toward the proximal ends of the first frames 45 in the extending direction so as to approach each other.

[0041] Furthermore, a pressed portion 50 that is pressed by the pressing portion 77 of the operating member 70 is connected to the connecting portion 43 of the operating portion 41 via an extension portion 51 .

[0042] As shown in Figures 3 and 4, the extension portion 51 is made up of a base portion 51a that extends to a certain width (meaning the length in the direction perpendicular to the extension direction of the opening / closing body 20; the same applies to other descriptions of the locking member) and a certain height (meaning the length along the extension direction E of the leg portion 60; the same applies to other descriptions of the locking member) and is connected to the connecting portion 44, and a tip portion 51b that is connected to the base portion 51a and has an inclined surface that gradually becomes higher as it moves away from the connecting portion 44.

[0043] The pressed portion 50 is a block-like member having a constant width and connected to the tip end 51b of the extending portion 51. As shown in Fig. 4, the pressed portion 50 has a pressed surface 53 at one end (upper end) in the height direction thereof, which is a flat surface extending along the extending direction E of the leg portion 60 and is pressed by the pressing protrusion 77a (see Fig. 5) of the pressing portion 77, and a restricting surface 54 which is a flat surface extending from one end (lower end) of the pressed surface 53 toward the tip end (end away from the connecting portion 44) of the pressed portion 50 in a direction perpendicular to the extending direction E of the leg portion 60 and which receives the pressing protrusion 77a to restrict excessive rotation of the operating member 70.

[0044] Furthermore, grooves 55 into which the shafts 82 of the operating member 70 are inserted are formed on both widthwise sides of the pressed portion 50. As shown in Fig. 4, each groove 55 has a slide groove 56 extending along the pressed portion movement direction F3, a guide groove 57 extending from one end of the slide groove 56 in the extending direction at an angle with respect to the extending direction of the slide groove 56, and a retaining portion 58 provided at one end of the guide groove 57 in the extending direction and configured to retain the shafts 82 (see Fig. 5) inserted into the groove 55 so as not to come off.

[0045] The slide groove 56 extends at a constant height in the pressed portion movement direction F3 from the base end (end close to the connecting portion 44) toward the tip end of the pressed portion 50 at the other end side (lower end side) in the height direction of the pressed portion 50. In addition, the guide groove 57 extends at a constant height obliquely outward from one end of the slide groove 56 in the extension direction (end away from the connecting portion 44) toward the middle part in the height direction of the tip end of the pressed portion 50.

[0046] The slide groove portion 56 and the guide groove portion 57 are connected to each other, and the groove width (height) is formed to be larger than the outer diameter of the shaft portion 82 of the operating member 70, so that the shaft portion 82 is inserted within the slide groove portion 56 and the guide groove portion 57 so as to be able to slide and rotate.

[0047] Furthermore, the holding portion 58 is formed at one end of the guide groove portion 57 in the extension direction (the end away from the connecting portion 44) so ​​as to narrow the opening width of the one end of the guide groove portion 57. The width of the holding portion 58 is formed smaller than the outer diameter of the shaft portion 82 of the operating member 70.

[0048] In addition, the shaft 82 is inserted from one end of the guide groove 57 in the extending direction, and the shaft 82 is configured to be movable along the guide groove 57 and the slide groove 56. Furthermore, when the pair of legs 60, 60 of the locking member 40, to which the operating member 70 is rotatably attached, are inserted into the pair of cylindrical protrusions 25, 25, and the shaft 82 is inserted from one end of the guide groove 57 and inserted into the slide groove 56 via the guide groove 57, the rotation support portion (rotation support hole 75) of the operating member 70 is rotatably supported by the rotation support portion of the fixed body or the opening / closing body (here, the rotation support protrusion 33 provided on the opening / closing body 20), and the operating member 70 is rotatably supported by the fixed body or the opening / closing body.

[0049] 3 and 4 , the pair of legs 60, 60 have their base ends 61 connected to the connecting portion between the tip of the second frame 46 and the base end of the third frame 47, and an extension portion 62 extends from the tip of this connecting portion by a predetermined length so as to bend perpendicular to the sliding direction F1 of the locking protrusion 65 and be spaced apart from the operating portion 41 including the annular portion 42, forming a generally crank-like shape as a whole. The extension portion 62 of the leg 60 and the operating portion 41 including the annular portion 42 are at different height positions. The direction in which the extension portion 62 of the leg 60 extends is referred to as the extending direction E of the leg 60.

[0050] A locking protrusion 65 protrudes in the sliding direction F1 from the tip of the extending portion 62 of each leg 60 in the extending direction. Furthermore, an inclined portion 68 is formed on the outer surface of the tip of the locking protrusion 65, making the locking protrusion 65 gradually thinner toward the tip of the locking protrusion 65. This inclined portion 68 is pressed by the ribs 27a, 27a provided on the base portion 21 when the leg 60 together with the guide member 90 is inserted into the internal space R (see FIG. 8).

[0051] Then, when the operating member 70 is rotated in the direction indicated by arrow K in FIG. 12 (the operating member 70 is rotated in the direction pushing up) from a state in which the pair of locking protrusions 65, 65 are inserted into the pair of locking portions 5, 5 and the opening / closing body 20 is closed relative to the opening 3, as shown in FIGS. 15 and 19, the pressing portion 77 rotates in the pressing direction F2 via the rotation support portion (the rotation support protrusions 33 and the rotation support hole 75) and presses the pressed portion 50 of the locking member 40.

[0052] As a result, while the movement of the locking protrusions 65, 65 in the pressed portion movement direction F3 is restricted by the regulating portions 28, 28 (see Figure 15), as shown in Figure 16, the pair of first frames 45, 45 elastically deform via the pressed portion 50, the extension portion 51, and the connecting portions 43, 44, and following this, the pair of second frames 46, 46 and the pair of third frames 47, 47 elastically deform.

[0053] As a result, the pair of locking protrusions 65, 65 slide away from the locking portions 5, 5, and as shown in Figure 20, the locking protrusions 65, 65 disengage from the locking portions 5, 5, thereby releasing the lock of the opening / closing body 20 from the closed state relative to the opening 3.

[0054] Furthermore, when the rotation operation of the operating member 70 is completed, the elastically deformed frames 45, 46, 47 elastically return to their original state, causing the locking protrusions 65, 65 to slide toward the locking portions 5, 5, and as shown in Figure 19, the locking protrusions 65, 65 engage with the locking portions 5, 5, and the opening / closing body 20 is locked in a closed state relative to the opening 3.

[0055] Here, the elastic restoring force of the pair of third frames 47, 47 mainly returns the pressing portion 77 to the state it was in before being pressed by the pressed portion 50, and the elastic restoring force of the pair of second frames 46, 46 and the pair of first frames 45, 45 causes the locking protrusions 65, 65 to slide in the direction approaching the locking portions 5, 5.

[0056] Furthermore, the operating portion 41 is disposed on the opening / closing body 20 in a state in which it is flexibly deformed before the pressing portion 77 presses against the pressed portion 50. In this embodiment, the pair of annular portions 42, 42 constituting the operating portion 41 are disposed on the opening / closing body 20 in a state in which they are flexibly deformed so as to be separated from or approach each other before the pressing portion 77 presses the pressed portion 50.

[0057] Furthermore, the operating portion 41 of the locking member 40 is configured to bias the pair of locking protrusions 65, 65 in the direction of insertion from the insertion holes 30, 95 so that the pair of locking protrusions 65, 65 engage with the pair of locking portions 5, 5.

[0058] However, if the locking member 40 is disposed on the opening / closing body 20 in a state in which the pair of annular portions 42, 42 are flexibly deformed as described above, the following situation occurs.

[0059] That is, as shown in Figure 17, when the pair of annular portions 42, 42 are flexibly deformed so that the tip ends (ends on the locking protrusion 65 side) of the pair of leg portions 60, 60 in the extension direction approach each other, the entire pressed portion 50 located in the center of the width direction of the locking member 40 rises up in the direction opposite to the extension direction E of the leg portions 60 (the pressed portion 50 rises up in the direction away from the bottom wall 22 of the base portion 21).

[0060] However, the above situation can be resolved by inserting the shaft 82 of the operating member 70 into the slide groove 56 of the groove 55 of the pressed portion 50, or by pressing the pressed portion 50 with the pressing portion 77 of the operating member 70 (as will be described in detail later). Note that, for ease of understanding, Fig. 17 exaggerates the lift of the pressed portion 50.

[0061] Next, a detailed description will be given of the operating member 70. As shown in Figures 5 and 6, the operating member 70 has a base portion 71, an operating portion 72, a pressing portion 77, and a shaft portion 82.

[0062] The base 71 is in the form of a block extending a predetermined length in the width direction of the opening / closing body 20. An operating unit 72 is connected to one long side of the base 71. The operating unit 72 is in the form of a substantially rectangular block so as to fit into the operating opening 31 formed in the opening / closing body 20, and is housed and disposed within the operating opening 31 so as to be able to protrude and retract.

[0063] Further, long plate-shaped support protrusions 73, 73 protrude from both widthwise ends on the other long side of the base 71. As shown in Fig. 10, these support protrusions 73, 73 are supported on ribs 27, 27 provided on the base 21 when the operating member 70 is rotatably supported by the opening / closing body 20 via a rotation support portion and before the pressing portion 77 presses the pressed portion 50, thereby preventing the operating portion 72 from falling off from the operation opening 31.

[0064] A pair of rotation support pieces 74, 74 are provided parallel to each other and extend diagonally outward (diagonally downward in FIGS. 5 and 6) from both widthwise ends on the other long side of the base 71. A circular rotation support hole 75 is formed at the tip of each rotation support piece 74 in the extending direction. As shown in FIGS. 13 and 14 , the pair of rotation support protrusions 33, 33 are arranged coaxially.

[0065] The corresponding rotation support protrusions 33 provided on the base portion 21 are inserted into each rotation support hole 75 from the outside in the width direction of the rotation support piece 74 (see FIGS. 13 and 14). As a result, the operating member 70 is rotatably attached to the opening / closing body 20 via the rotation support protrusions 33 and the rotation support holes 75 that constitute the rotation support portion. That is, in this embodiment, the rotation support holes 75 form the "rotation support portion" provided on the operating member 70 of the present invention.

[0066] In addition, an inclined surface 75a that gradually becomes thinner toward the tip of the rotation support piece 74 in the extension direction is formed on the outer width surface of the tip of each rotation support piece 74 in the extension direction, at the outer peripheral edge of the rotation support hole 75. This inclined surface 75a, together with the inclined surface 33a formed on the rotation support protrusion 33, improves the ease of inserting the rotation support protrusion 33 into the rotation support hole 75.

[0067] A raised portion 76 is provided at the center in the width direction at the connecting portion between the base 71 and the operating portion 72, which raises the operating member 70 and rotatably houses the pressed portion 50 of the locking member 40. A pressing portion 77 is provided at one end (upper end) of the raised portion 76 on the tip side (opposite the operating portion 72) in the height direction (meaning the direction perpendicular to the width direction and short side direction of the base 71; the same applies to other descriptions of the operating member) and which presses the pressed portion 50 of the locking member 40. The pressing portion 77 has a pressing protrusion 77a in the shape of a substantially square protrusion, and this pressing protrusion 77a presses the pressed surface 53 of the pressed portion 50.

[0068] Furthermore, a pair of elongated plate-shaped movement suppressing portions 80, 80 are arranged parallel to each other along the height direction of the operating member 70 on both widthwise sides of the pressing portion 77. As shown in Figures 2 and 8, the pair of movement suppressing portions 80, 80 are arranged outside both widthwise sides of the pressed portion 50 of the locking member 40 in a state in which the operating member 70 is attached to the locking member 40.

[0069] Furthermore, shaft portions 82, 82 each having a substantially cylindrical projection shape (a substantially circular pin shape) protrude from the inner surface (the surface facing the mating movement suppressing portion 80) of one end (lower end) in the height direction of the pair of movement suppressing portions 80, 80. As shown in Figures 13 and 14, the pair of shaft portions 82, 82 are arranged coaxially.

[0070] Then, by inserting the pair of shafts 82, 82 into the pair of grooves 55, 55 of the locking member 40, the operating member 70 is rotatably attached to the locking member 40 via the grooves 55 and the shafts 82. Furthermore, the operating member 70 attached to the locking member 40 is allowed to rotate relative to the locking member 40 before the locking member 40 and the operating member 70 are attached to the opening / closing body 20, and is also allowed to rotate relative to the locking member 40 after the locking member 40 and the operating member 70 are attached to the opening / closing body 20.

[0071] That is, the pair of shafts 82, 82 are inserted into the groove 55 to allow rotation of the operating member 70 before and after the locking member 40 and the operating member 70 are attached to the opening / closing body 20. The process of attaching the operating member 70 to the locking member 40 will be described in detail later.

[0072] In addition, the pressing portion 77 is offset relative to the rotation support portion in a direction intersecting the direction of movement F3 of the pressed portion, and the axis centers C2, C2 of the pair of shaft portions 82, 82 are aligned (coaxial) or located close to the rotation center C1 of the pair of rotation support portions.

[0073] 12, when viewed from a direction along the rotation center C1 of the rotation support hole 75, which is the rotation support portion, the pressing protrusion 77a constituting the pressing portion 77 is offset in a direction perpendicular to the pressed portion movement direction F3 (a direction perpendicular to the pressed portion movement direction F3 and the direction along the rotation center C1 of the rotation support portion, which can also be said to be the height direction of the operating member 70) relative to the rotation support hole 75. In addition, the axis centers C2 of the pair of shaft portions 82 coincide with the rotation center C1 of the pair of rotation support holes 75 (see FIG. 13).

[0074] Furthermore, the axis C2 of the shaft portion 82 is offset in the direction F3 of movement of the pressed portion relative to the rotation center C1 of the rotation support portion, and is positioned coincident with or close to the direction intersecting the direction F3 of movement of the pressed portion relative to the rotation center C1 of the rotation support portion.

[0075] 12, when viewed from a direction along the rotation center C1 of the rotation support hole 75, which is the rotation support part, the axis C2 of the shaft part 82 is misaligned in the pressed part movement direction F3 with respect to the rotation center C1 of the rotation support hole 75, and coincides with a direction orthogonal to the pressed part movement direction F3 with respect to the rotation center C1 of the rotation support hole 75 (a direction orthogonal to the pressed part movement direction F3 and the direction along the rotation center C1 of the rotation support part, which is the height direction of the operating member 70) (see FIG. 13). Note that the amount of misalignment of the shaft part 82 in the pressed part movement direction F3 with respect to the rotation support part in FIG. 12 is exaggerated for ease of understanding.

[0076] Furthermore, an inverted L-shaped elastic piece 84 that is capable of bending and deforming is provided on the other long side of the base 71 between the rotation support piece 74 and the movement suppressing portion 80. As shown in Figure 10, this pair of elastic pieces 84, 84 is disposed opposite the pair of elastic force applying portions 34, 34 provided on the base portion 21 in a state in which the operating member 70 is rotatably attached to the opening / closing body 20.

[0077] 12, when the operating member 70 is rotated in a direction in which the operating portion 72 is pushed up and approaches a cover portion (not shown) of the opening / closing body 20, the pair of elastic pieces 84, 84 come into contact with the pair of elastic force applying portions 34, 34 and are flexibly deformed. As a result, the elastic restoring force of the pair of elastic pieces 84, 84 urges the operating portion 72 to rotate in the direction opposite to the arrow K in FIG. 12 (in a direction in which the operating portion 72 moves away from the cover portion (not shown) of the opening / closing body 20).

[0078] Next, the guide member 90 will be described in detail with reference to Figure 7. The guide member 90 of this embodiment has a bottom wall 91, a pair of side walls 92, 92 extending from the bottom wall 91, and a front wall 93 connecting the pair of side walls 92, 92 and having an insertion hole 95 formed therein for inserting and removing the locking protrusion 65. The guide member 90 is frame-shaped and open on the side opposite the bottom wall 91. A first elastic engagement portion 96 is formed on the front wall 93, and a second elastic engagement portion 97 is also formed on the side opposite the front wall 93.

[0079] The guide member 90 is attached to the leg 60 in a state where it is prevented from coming off by pushing it into the tip side of the leg 60 of the locking member 40 in the extension direction E of the leg 60 and sliding it in a direction perpendicular to the extension direction E of the leg 60 (see FIG. 8 ). Furthermore, the leg 60 to which the guide member 90 is attached is inserted into the cylindrical protrusion 25, and the first elastic engaging portion 96 engages with the rear peripheral edge portion opposite the bottom wall 91 of the insertion hole 30, and the second elastic engaging portion 97 engages with the engaging groove 26 a of the engaging rib 26 of the base portion 21, thereby preventing the guide member 90 from coming off from the internal space R of the cylindrical protrusion 25 (see FIGS. 19 and 20 ).

[0080] (Variant example) The shape, structure, layout, etc. of the locking portion that constitutes the locking device of the opening / closing body in the present invention, the opening / closing body, the locking member, the operating member, the guide member, and each part that constitutes each member (for example, the annular portion of the locking member, each frame, leg portion, pressed portion, locking protrusion, etc., and further the operating portion, pressing portion, shaft portion, etc. of the operating member) are not limited to the above-mentioned embodiments.

[0081] Furthermore, in this embodiment, as described above, the present invention is applied to a structure in which an opening / closing body such as a lid is attached to the opening of a console box in an openable / closable manner, but it may also be applied to a structure in which a box-shaped glove box is attached to the opening of an instrument panel in an openable / closable manner (in this case, the instrument panel constitutes the "fixed body" and the glove box constitutes the "opening / closing body"), or to a structure in which a lid is attached to the opening of an instrument panel in an openable / closable manner (in this case, the instrument panel constitutes the "fixed body" and the lid constitutes the "opening / closing body"), and can be widely used in opening / closing structures for various opening / closing bodies that open and close the opening of a fixed body.

[0082] Furthermore, in this embodiment, the locking portion 5 is provided on the fixed body 1 side, the locking member 40, operating member 70, and guide member 90 are arranged on the opening / closing body 20 side, and the cylindrical protrusion 25 protrudes from the opening / closing body 20, but for example, the locking portion may be provided on the opening / closing body side, and the locking member, operating member, and guide member may be arranged on the fixed body side, and the cylindrical protrusion may protrude from the fixed body.

[0083] In the case of a structure in which the locking portion 5 is provided on the fixed body 1 side and the pair of locking protrusions 65, 65 are biased in a direction away from each other by the biasing force of the pair of annular portions 42, 42, as in this embodiment, when the operating member 70 is rotated, the pair of locking protrusions 65, 65 slide in a direction toward each other against the biasing force of the pair of annular portions 42, 42 (see Figures 16 and 20).

[0084] However, the pair of locking protrusions may be configured to be biased toward each other by the biasing force of the pair of annular portions, and when the operating member is rotated, the pair of locking protrusions may slide away from each other against the biasing force of the pair of annular portions.

[0085] It is also conceivable that the locking portion is provided on the opening / closing body side (for example, a pair of concave locking portions is provided on both sides of the opening / closing body in the width direction), and the pair of locking protrusions are urged toward each other by the urging force of the pair of annular portions. In such a structure, when the operating member is rotated, the pair of locking protrusions slide in directions away from each other against the urging force of the pair of annular portions.

[0086] Furthermore, although the locking portion 5 in this embodiment is hole-shaped, the locking portion may not be hole-shaped, but may be recessed, protruding, frame-shaped, etc. Furthermore, the locking portion may be provided in the opening / closing body rather than in an opening in the fixed body.

[0087] Furthermore, in this embodiment, the rotation support portion provided on the opening / closing body 20 side is a protrusion-shaped rotation support protrusion 33, and the rotation support portion provided on the operating member 70 side is a hole-shaped rotation support hole 75, but the rotation support portion on the opening / closing body side may be a through hole or a recess of a predetermined depth, and the rotation support portion on the operating member side may be a protrusion or pin inserted into a hole or recess, and any structure may be used as long as it can rotatably support the operating member relative to the fixed body or opening / closing body.

[0088] Furthermore, in this embodiment, groove portions 55 are formed on both sides of the width of the pressed portion 50, and a pair of shaft portions 82, 82 are also protruded from the operating member 70, but it is also possible to form the groove portion 55 on only one side of the width of the pressed portion 50, and to provide only a shaft portion 82 corresponding to the groove portion 55 on one side on the operating member 70.

[0089] (Operation and Effect) Next, the operation and effect of the locking device 10 configured as described above will be described.

[0090] First, a description will be given of the assembly process of the locking device 10. First, as described above, the pair of guide members 90, 90 are attached to the pair of legs 60, 60 of the locking member 40.

[0091] Thereafter, the operating member 70 is attached to the locking member 40. At this time, the pair of shafts 82, 82 of the operating member 70 are inserted into the grooves 55 of the pressed portion 50 of the locking member 40. Specifically, the shafts 82 are press-fitted into the retaining portions 58 of the grooves 55, and the shafts 82 are inserted into the guide grooves 57 through the retaining portions 58, whereby the operating member 70 can be attached to the locking member 40 in a rotatable manner and in a state where it is held in place so as not to come off.

[0092] The pair of shafts 82 are positioned within the guide grooves 57, allowing the operating member 70 to rotate relative to the locking member 40. If the pair of shafts 82 are positioned within the slide grooves 56 beyond the guide grooves 57, the rotation angle of the operating member 70 relative to the locking member 40 is limited, and when the operating member 70 is attached to the opening / closing body 20, the rotation support pieces 74 and rotation support holes 75 of the operating member 70 interfere with the rotation support protrusions 33 of the opening / closing body 20. Therefore, the amount of movement of the pair of shafts 82 relative to the grooves 55 is limited to a range that fits within the guide grooves 57, as described above.

[0093] Furthermore, an assembly in which the operating member 70 is attached to the locking member 40 is referred to as an assembly 100. In this embodiment, a pair of guide members 90 are attached to a pair of legs 60 of the locking member 40, and therefore the assembly 100 is made up of the locking member 40, the operating member 70, and the pair of guide members 90.

[0094] Next, the pair of legs 60, 60 of the assembly 100 are aligned with the corresponding pair of openings 24, 24 of the base portion 21, and then the pair of legs 60, 60 together with the guide member 90 are inserted into the pair of cylindrical protrusions 25, 25, as shown by the arrow in Fig. 8. At this time, as shown in Fig. 11, the operating member 70 is slightly rotated relative to the locking member 40 via the groove portion 55 and the shaft portion 82 in a direction in which the pressing portion 77 approaches the pressed portion 50, so that the tip of the operating portion 72 does not interfere with the peripheral wall 23 of the base portion 21.

[0095] Then, the first elastic engaging portion 96 and the second elastic engaging portion 97 are elastically deformed by the inner wall surface of the cylindrical protruding portion 25, the ribs, etc., while the leg portion 60 is pushed into the cylindrical protruding portion 25. Then, when the leg portion 60 is pushed into the cylindrical protruding portion 25 by a predetermined amount, the first elastic engaging portion 96 engages with the periphery of the insertion hole 30, and the second elastic engaging portion 97 engages with the engaging groove 26 a.

[0096] As a result, the pair of guide members 90, 90 are held against the pair of cylindrical protrusions 25, 25 by the first elastic engaging portions 96 and the second elastic engaging portions 97, and the pair of guide members 90, 90 are attached to the pair of cylindrical protrusions 25, 25, and ultimately the pair of guide members 90, 90 are attached to the opening / closing body 20. In addition, by attaching the pair of guide members 90, 90 to the pair of cylindrical protrusions 25, 25, the entire locking member 40 is attached to the opening / closing body 20 via the pair of guide members 90, 90.

[0097] 9 and 11, in the above state, the operating member 70 is not yet attached to the opening / closing body 20. Therefore, the operating member 70 is now pressed against the locking member 40 in the pressed portion movement direction F3.

[0098] Then, the pair of shafts 82 are guided by the pair of guide grooves 57, the operating member 70 is pushed into the locking member 40, and when the pair of shafts 82 pass through the other ends of the pair of guide grooves 57, they are inserted into the pair of slide grooves 56. At the same time, the pair of rotation support protrusions 33 are inserted from the outside of the pair of rotation support holes 75, via the inclined surfaces 75a of the rotation support holes 75 and the inclined surfaces 33a of the rotation support protrusions 33.

[0099] 12 to 14, the operating member 70 can be rotatably attached to the opening / closing body 20 via the rotation support protrusion 33 and the rotation support hole 75 that constitute the rotation support portion. In this state, the operating portion 72 protrudes a predetermined amount from the operation opening 31, and the pressing protrusion 77a is disposed in close proximity to and facing the pressed surface 53 of the pressed portion 50 (see FIG. 12).

[0100] In this locking device 10, the operating member 70 has a shaft 82 in addition to a rotation support portion (here, rotation support hole 75), so that the operating member 70 can be rotatably attached to the locking member 40 by the simple operation of inserting this shaft 82 into the groove 55 of the locking member 40. As a result, in the locking device 10 having the rotatable operating member 70, the base member in the locking device described in Patent Document 1 is not necessary, which reduces the number of parts in the locking device as a whole and improves the ease of attaching the operating member 70 to the locking member 40.

[0101] Furthermore, this locking device 10 has a structure in which a single operating member 70 that combines the shaft portion 82 and the rotation support portion can be rotatably attached to two members, namely the locking member 40 and can be attached to the opening / closing body 20, thereby simplifying the rotation structure of the locking device 10 and the installation and mounting process.

[0102] Furthermore, in this locking device 10, the operating member 70 is attached to the locking member 40, and before the locking member 40 and the operating member 70 are attached to the opening / closing body 20, the operating member 70 is rotatable relative to the locking member 40.

[0103] Therefore, before attaching and positioning the assembly 100 in which the operating member 70 is attached to the locking member 40 to the opening / closing body 20, the assembly is temporarily placed in a retracted state in which the rotation support portion (rotation support hole 75) on the operating member 70 side does not interfere with the rotation support portion (rotation support protrusion 33) on the opening / closing body 20 side, and after positioning the assembly of the locking member 40 and operating member 70 on the opening / closing body 20, the operating member 70 can be rotated relative to the locking member 40 so that it is rotatably supported via the rotation support portion (rotation support hole 75 is rotated by the rotation support protrusion 33), and the operating member 70 can be attached to the opening / closing body 20.

[0104] That is, during the placement of the assembly 100 on the opening / closing body 20, the rotation support protrusion 33, which is the rotation support portion on the opening / closing body 20 side, does not interfere with the rotation support hole 75, which is the rotation support portion on the operating member 70 side, or the rotation support piece 74 having the rotation support hole 75 formed therein. As a result, the workability of attaching the assembly 100 to the opening / closing body 20 can be improved.

[0105] 19 shows a state in which the opening 3 of the fixed body 1 is closed by the opening / closing body 20. That is, the pair of locking protrusions 65, 65 are inserted through the insertion holes 30, 95 and are engaged with the pair of locking portions 5, 5, and the state is the same as before the pressing portion 77 presses the pressed portion 50 as shown in FIG.

[0106] 12 , when the operating member 70 is rotated from this state by pushing up the operating portion 72 in a direction approaching a cover portion (not shown) of the opening / closing body 20, the operating member 70 rotates relative to the locking member 40 via the rotation support protrusions 33 and the rotation support holes 75 on the widthwise outer side of the operating member 70, and the operating member 70 rotates relative to the opening / closing body 20 via the slide groove portions 56 and the shaft portion on the widthwise inner side of the operating member 70 (which can also be said to be axially inner than the rotation support protrusions 33 and the rotation support holes 75). In other words, the operating member 70 rotates relative to the locking member 40 and the opening / closing body 20 on the widthwise outer and inner sides of the operating member 70, respectively.

[0107] 18, the pressing portion 77 is pressed against the pressed surface 53 of the pressed portion 50 by the pressing protrusion 77a of the pressing portion 77, and the pressed portion 50 moves in the pressed portion movement direction F3. Furthermore, while the movement of the pair of locking protrusions 65 in the pressed portion movement direction F3 is restricted by the pair of restricting portions 28 (see FIG. 15), the pair of first frames 45 elastically deform via the pressed portion 50, the extension portion 51, and the connecting portions 43, 44, as shown in FIG. 16, and the pair of second frames 46 and the pair of third frames 47 elastically deform accordingly.

[0108] As a result, the pair of locking protrusions 65, 65 slide away from the pair of locking sections 5, 5, and as shown in Figure 20, the pair of locking protrusions 65, 65 disengage (come out) from the pair of locking sections 5, 5, thereby releasing the lock on the opening 3 from the closed state of the opening / closing body 20, and the opening / closing body 20 can be opened from the opening 3 of the fixed body 1.

[0109] In this embodiment, a leg 60 is provided from the operating portion 41 of the locking member 40, extending in a direction intersecting the sliding direction F1 of the locking protrusion 65 and inserted into the internal space R, the locking protrusion 65 protruding from the leg 60 in the sliding direction F1, the pressing portion 77 is provided offset from the rotation support portion (rotation support hole 75) in a direction intersecting the pressed portion movement direction F3, and the axis centers C2, C2 of the pair of shaft portions 82, 82 are provided in a position that is coincident (coaxial) with or close to the rotation center C1 of the pair of rotation support holes 75.

[0110] When the pressed portion 50 is pressed by the pressing portion 77, the locking member 40 tends to rise up in the direction opposite (reverse direction) to the extension direction E of the leg portion 60. At this time, if the axis C2 of the shaft portion 82 is not aligned with or located close to the rotation center C1 of the rotation support portion, when the pressed portion 50 is pressed by the pressing portion 77, the shaft portion 82 also rotates together with the operating member 70, and it is not possible to prevent the locking member 40 from rising up.

[0111] On the other hand, in the above-described aspect of the locking device 10, the structure of the leg portion 60 and the arrangement of the pressing portion 77 are configured as described above, and the axis C2 of the shaft portion 82 is located in close proximity to the rotation center C1 of the rotation support portion (rotation support hole 75), so that the locking member 40 can be prevented from floating up.

[0112] That is, since the pressing portion 77 is provided offset relative to the rotation support portion in a direction intersecting the pressed portion movement direction F3, when the pressed portion 50 is pressed by the pressing portion 77, a pressing force from the pressing portion 77 is applied in a direction that presses the locking member 40 as a whole downward toward the extending direction E of the leg portion 60. In addition to this pressing force from the pressing portion 77, the axis centers C2, C2 of the pair of shaft portions 82, 82 are provided at positions that coincide with or are close to the rotation center C1 of the pair of rotation support holes 75, so that the shaft portions 82 are inserted and arranged in the groove portions 55 so that each shaft portion 82 is reliably accommodated in the height direction (the direction along the extending direction E of the leg portion 60) of the groove portions 55 (here, particularly the slide groove portions 56) of the locking member 40.

[0113] As a result, even if the locking member 40 tries to float up, the shaft portion 82 abuts against the inner surface (upper surface) of the groove portion 55 in the height direction, restricting further floating, so that the entire locking member 40 can be prevented from floating up.

[0114] Furthermore, as shown in Figure 11, in this embodiment, the groove portion 55 has a slide groove portion 56 extending along the pressed portion movement direction F3, and a guide groove portion 57 extending from one end of the extension direction of the slide groove portion 56 at an angle with respect to the extension direction of the slide groove portion 56.

[0115] According to the above aspect, the guide groove portion 57 that constitutes the groove portion 55 makes it easier to rotate the operating member 70 to an appropriate rotation angle relative to the locking member 40 when the assembly 100, in which the operating member 70 is attached to the locking member 40, is placed in a retracted state in which the rotation support portion (rotation support hole 75) of the operating member 70 does not interfere with the rotation support portion of the fixed body 1 or the opening / closing body 20 (here, the rotation support protrusion 33 provided on the opening / closing body 20) before being placed on the fixed body 1 or the opening / closing body 20, thereby further improving the ease of installation of the assembly 100 to the fixed body 1 or the opening / closing body 20.

[0116] Furthermore, as shown in Figure 12, in this embodiment, the axis C2 of the shaft portion 82 is offset in position from the rotation center C1 of the rotation support portion in the direction F3 in which the pressed portion moves, and is located at a position that coincides with or is close to the rotation center C1 of the rotation support portion in a direction that intersects the direction F3 in which the pressed portion moves.

[0117] According to the above aspect, since the axis C2 of the shaft portion 82 is disposed as described above, the force W with which the operating portion 41 of the locking member 40 attempts to elastically return acts from the pressed portion 50 to the pressing portion 77, causing the operating member 70 to rotate in the direction opposite to the pressing direction F2, thereby suppressing rattling of the operating member 70.

[0118] That is, when the amount of positional deviation between the rotation center C1 of the rotation support portion and the axis C2 of the shaft portion 82 in the direction F3 of movement of the pressed portion is defined as "L," a rotation moment M acts in the direction opposite to the pressing direction F2 (M = W × L) in relation to the above-mentioned force W. This rotation moment M causes the operating member 70 to rotate in the direction opposite to the pressing direction F2, thereby suppressing rattling of the operating member 70.

[0119] Furthermore, as shown in Figures 2, 8, etc., a pair of movement suppression portions 80, 80 are provided between the locking member 40 and the operating member 70 to suppress movement of the pressed portion 50 and the pressing portion 77 in a direction along the rotation center C1 of the rotation support portion (rotation support hole 75).

[0120] According to the above aspect, when the operating member 70 is attached to the locking member 40, a pair of movement suppression portions 80, 80 are arranged on the outside of both widthwise sides of the pressed portion 50 of the locking member 40, so that lateral shifting (shifting along the rotation center C1 of the rotation support portion) between the locking member 40 and the operating member 70 can be suppressed.

[0121] It should be noted that the present invention is not limited to the above-described embodiment, 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.
