Description

Technical Field

[0001] The present invention relates to a locking device for an opening / closing body, used to lock an opening / closing body that is installed in a way that allows it to be opened and closed into a closed state. Background Technology

[0002] For example, a lid or other opening / closing device is installed at the opening of a fixed body such as a seat storage compartment in a car. In most cases, a locking device is provided between such an opening and the opening / closing device, which is configured to lock when the opening / closing device is closed and unlock when the opening / closing device is opened.

[0003] Patent Document 1 describes a locking device installed on an opening / closing body that allows the opening of a fixed body to be opened and closed. The locking device includes: a base member; a locking rod member slidably supported on the base member; and a drive member that moves according to a user's operation to slide the locking rod member. The locking rod member has: a locking portion that can engage / disengage with a locking hole in the fixed body; a first rod portion extending in the sliding direction of the locking rod member; and a second rod portion extending in a direction intersecting the sliding direction, connecting the first rod portion and the locking portion.

[0004] An operating member is rotatably attached to the front end of the base member. Furthermore, a pair of spring members, separate from the drive member, are sandwiched between the base end of the drive member and the spring support portion on the base end side of the base member.

[0005] Furthermore, when the operating member is rotated, the driving member resists the elastic force applied by a pair of spring members and slides towards the base end of the driving member and closes to the base end of the base member. The locking part of a pair of locking rod members is pulled into the insertion hole of the opening and closing body by a predetermined length, thereby enabling the opening and closing of the opening and closing body from the opening of the fixed body.

[0006] Furthermore, when the operation of the operating member ends, the driving member slides in the direction where the base end of the driving member separates from the base end of the base member by the elastic force applied by a pair of spring members, returning (restoring) to the state before the operation of the operating member.

[0007] Existing technical documents Patent documents Patent Document 1: WO2022 / 004532A1 Summary of the Invention

[0008] The problem that the invention aims to solve In the locking device of the aforementioned Patent Document 1, in order to return the driving member to the state before the operation of the operating member, a pair of spring members that are separate from the driving member are required, resulting in a large number of parts and a complex structure.

[0009] Therefore, the object of the present invention is to provide a locking device for an opening and closing body that can reduce the number of components and simplify the structure.

[0010] Solution for solving the problem To achieve the above objective, the present invention provides a locking device for an opening / closing body, wherein the opening / closing body is installed in an opening portion of a fixed body in an openable / closable manner. The locking device comprises: a locking portion disposed 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 an operating member disposed on the other of the fixed body or the opening / closing body, having an operating portion and a pressing portion connected to the operating portion. The locking member comprises: a pair of annular portions; a connecting portion connecting the pair of annular portions to each other and having a pressing portion pressed by the pressing portion; and a pair of locking protrusions protruding from the pair of annular portions and sliding relative to the locking portion to engage / disengage with the locking portion. The fixed body or the opening / closing body comprises... The device includes a limiting portion that restricts the movement of the locking protrusion in the same direction as the pressing direction of the pressing portion on the pressed portion when the operating member is operated to press the pressed portion. The connecting portion is disposed offset relative to the limiting portion in the pressing direction of the pressing portion. The pair of annular portions have: a pair of first frames that are elastically deformable, disposed on both sides of the pressing portion and extending in a direction opposite to the pressing direction of the pressing portion; a pair of second frames that are elastically deformable and extend from the front end side of the extending direction of the pair of first frames in a direction separating from each other; and a pair of third frames that are elastically deformable and have portions that extend obliquely from the front end side of the extending direction of the pair of second frames toward the base end side of the extending direction of the first frames, the front end side of the extending direction being connected to the base end side of the extending direction of the first frames.

[0011] Invention Effects According to the locking device of the opening and closing body of the present invention, the locking member is composed of a pair of annular portions including multiple frames, a connecting portion and a pair of locking protrusions. When the operating member is operated, each frame of the pair of annular portions will elastically deform, thereby enabling the pair of locking protrusions and the operating member to return to the state before the operation of the operating member, thus reducing the number of parts and simplifying the structure.

[0028] (First embodiment of the locking device for the opening and closing body) Hereinafter, a first embodiment of the locking device for the opening and closing body of the present invention will be described with reference to the accompanying drawings.

[0029] like Figure 10 and Figure 11 As shown, the locking device 10 (hereinafter referred to as "locking device 10") of the opening and closing body in this embodiment locks the opening and closing body 20, such as the lid of the opening 3 of the fixed body 1 such as the intercom storage box of a vehicle, to a closed state relative to the opening 3 of the fixed body 1, and can open the opening and closing body in the locked state. It should be noted that the opening and closing body 20 extends with a predetermined length, but for convenience, the front end (one end) side in the extension direction is shown.

[0030] like Figure 1 , Figure 4 , Figure 8 , Figure 10 As shown, the locking device 10 of this embodiment mainly consists of the following structure: a pair of locking parts 5, 5, provided on the fixing body 1 (see reference). Figure 10 The locking member 40 is disposed on the opening and closing body 20 and has a pair of locking protrusions 55, 55 that engage / disengage with a pair of locking parts 5, 5; the operating member 60 is disposed on the opening and closing body 20 and has an operating part 61 and a pressing part 63 connected to the operating part 61, and operates the locking member 40; a pair of guide members 70, 70 guide the sliding action of the pair of locking protrusions 55, 55.

[0031] It should be noted that the operating member 60 is configured to slide along the extending direction of the opening / closing body 20, and its pressing part 63 presses against the pressed part 43 of the locking member 40. For example... Figure 4 and Figure 8 As shown, the pressing direction of the pressing part 63 on the pressed part 43 is set as "pressing direction F1".

[0032] Furthermore, the pair of locking protrusions 55, 55 are configured to slide in a direction intersecting the extending direction of the opening / closing body 20, engaging / disengaging with the pair of locking parts 5, 5. For example... Figure 4 and Figure 8 As shown, the sliding direction of a pair of locking protrusions 55, 55 is set as "sliding direction F2".

[0033] Moreover, such as Figure 10As shown, a cylindrical protrusion 25 with an internal space R protrudes from the opening / closing body 20. An insertion hole 30 and an insertion hole 75 (see reference) are formed in the cylindrical protrusion 25 and the guide member 70, communicating with the internal space R and allowing the locking protrusion 55 to be inserted. Figure 10 ).

[0034] In addition, such as Figure 2 , Figure 5 , Figure 6 As shown, the locking member 40 of this embodiment includes: a pair of annular portions 41, 41; a connecting portion 42 that connects the pair of annular portions 41, 41 to each other and has a pressing portion 43 that is pressed by the pressing portion 63 of the operating member 60; a pair of legs 50, 50 that extend from the pair of annular portions 41, 41 in a direction intersecting the sliding direction F2 of the locking protrusion 55 and are inserted into the internal space R of the cylindrical protrusion 25; and a pair of locking protrusions 55, 55 that protrude from the pair of legs 50, 50 in the sliding direction F2 of the locking protrusion 55.

[0035] Moreover, such as Figure 8 As shown, the opening / closing body 20 has limiting parts 7, 7 that receive the sides of a pair of locking protrusions 55, 55 when the pressing part 63 presses the pressed part 43 by the operating member 60, and restrict the movement of the locking protrusions 55 in the same direction as the pressing direction F1 of the pressing part 63 on the pressed part 43. Each limiting part 7 is configured to receive the side of the corresponding locking protrusion 55 located on the pressing direction F1 side (towards F1 side) of the pressing part 63.

[0036] like Figure 10 As shown, the fixing body 1, which serves as a storage box between seats, has stepped portions 4 on both sides of the opening 3 in the width direction, which support the two sides of the opening and closing body 20 in the width direction. A pair of locking portions 5, 5 are formed on the bottom side of the fixing body 1, which is closer to the stepped portions 4.

[0037] In this embodiment, the opening / closing body 20 is composed of a base portion 21 with an opening at the top and a cover portion 27 that covers the opening at the top of the base portion 12. It should be noted that, for ease of explanation, in... Figure 1 , Figure 4 , Figures 8-11 Only the base portion 21 is shown in the diagram.

[0038] The base portion 21 has a generally elongated plate-shaped bottom wall 22 extending along one direction for a predetermined length and a peripheral wall 23 erected from the periphery of the bottom wall 22, which is a frame-shaped structure with an opening at the top. It should be noted that the base end (other end) of the opening / closing body 20, which extends in a direction not shown in the figure, is rotatably supported on the opening portion 3 of the fixing body 1, thereby opening and closing the opening portion 3 of the fixing body 1.

[0039] Furthermore, a pair of openings 24, 24, which are approximately quadrilateral holes, are formed on both sides of the base portion 21 at its front end (one end) in the extending direction and on both sides of the base portion 21 in the width direction (orthogonal to the extending direction). Moreover, cylindrical protrusions 25, 25, protrude from the periphery of the back side (outer side) of the pair of openings 24, 24, respectively. Guide members 70 are respectively housed in the internal space R of each cylindrical protrusion 25.

[0040] It should be noted that the aforementioned "back side" or "rear side" refers to the side or surface located in the direction of closing of the opening / closing body 20. On the other hand, the "surface side" or "surface side" refers to the side opposite to the "back side" or "rear side," that is, the side or surface located in the direction of opening of the opening / closing body from the opening of a fixed body such as a vehicle. Furthermore, when the fixed body is installed in a vehicle, the side of the vehicle's interior space can be designated as the "surface side" or "surface side," and the opposite side can be designated as the "back side" or "rear side."

[0041] It should be noted that the terms "front side", "surface side", "back side", and "rear side" mentioned above have the same meaning in other components (locking components, operating components, guiding components, etc.) described below.

[0042] Each cylindrical protrusion 25 has multiple wall portions and is a bottomed, generally quadrilateral cylindrical shape with an internal space R on the inside.

[0043] like Figure 10 As shown, engaging ribs 26 extending along the protruding direction of each cylindrical protrusion 25 are formed on the inner surface (facing the internal space R) of the wall portion 25a that is disposed opposite to the cylindrical protrusion 25 on the opposite side. Engaging grooves 26a are formed in the engaging ribs 26 for engaging the second elastic engaging portion 81 of the guide member 70.

[0044] Furthermore, at a position where the wall portion 25b of each cylindrical protrusion 25 is disposed separately from the cylindrical protrusion 25 on the opposite side and close to the bottom, an insertion hole 30 in the shape of a generally quadrilateral hole is formed for the locking protrusion 55 to be inserted.

[0045] Moreover, such as Figure 1 As shown, a plurality of ribs 28 are formed on the inner surface of the bottom wall 22 of the base portion 21 and on the outer (inner) periphery of the opening 24. On the wall portion 25b side of the cylindrical protrusion 25 among these ribs, a pair of ribs 28a, 28a (see reference) extend obliquely inward toward the bottom side of the cylindrical protrusion 25. Figure 10 ).

[0046] These ribs 28a, 28a become the parts that, when the pair of legs 50, 50 of the locking member 40 are respectively inserted into the internal space R of the pair of cylindrical protrusions 25, 25, press the inclined portion 57 of the locking protrusion 55 (described later), causing the pair of locking protrusions 55, 55 to slide in a direction toward each other.

[0047] In addition, such as Figure 1 As shown, a protruding hole 31, elongated in shape, is formed in the portion of the peripheral wall 23 constituting the base portion 21 at the front end in the extending direction of the base portion 21. One end of the operating member 60 protrudes from this protruding hole 31 (see reference). Figure 4 ).

[0048] Furthermore, a pair of sidewalls 32, 32, extending parallel to each other from the two sides of the peripheral wall 23 in the width direction of the protruding hole 31 toward the base end side in the extending direction of the base portion 21, are formed in a roughly "U" shape. A spring-mounted protrusion 33 is provided between these two sidewalls 32, 32. Moreover, guide grooves 34 extending in the extending direction of the base portion 21 are formed on the side portions of the two sidewalls 32, 32 on the side portions of the spring-mounted protrusions 33.

[0049] The operating member 60 will be described in detail below. The operating member 60 of this embodiment has: an operating part 61, which is generally quadrilateral plate-shaped; and a pressing part 63, which is generally quadrilateral prism-shaped and extends from the other end of the operating part 61 and from the center of its width direction for a predetermined length.

[0050] Multiple guide protrusions 65 are provided on both sides of the operating part 61 in the width direction and on both the front and back sides. The pair of guide protrusions 65, 65 on the back side of the operating part 61 are inserted into a pair of guide grooves 34, 34 provided in the opening and closing body 20, thereby guiding the sliding action of the operating member 60 along the pressing part 63 against the pressed part 43 in the pressing direction F1.

[0051] In addition, such as Figure 8 As shown by arrow F1, the configuration is such that when the front end of the pressing part 63 in the extending direction slides toward the base end side in the extending direction of the opening and closing body 20, the front end of the pressing part 63 presses the pressed part 43 of the locking member 40.

[0052] Furthermore, a spring mounting hole 67, which is generally elongated, is formed in the operating part 61. The spring mounting hole 67 is configured such that a spring mounting protrusion 33 (see reference 21) provided on the base part 21 is inserted into the spring mounting hole 67. Figure 4 Furthermore, a helical spring (not shown) is clamped between the spring mounting protrusion 33 and the spring mounting hole 67. This helical spring allows the operating member 60 to be positioned while suppressing swaying at the front end of the base portion 21 in its extending direction.

[0053] Return to the description of open / closed body 20, such as... Figure 1 As shown, a support rib 35, which is a protrusion, is provided extending from the center of the other end of the spring configuration protrusion 33 toward the base end side in the extending direction of the opening and closing body 20. The support rib 35 supports the back side of the pressing part 63, so that the pressing action of the pressing part 63 on the pressed part 43 is stable.

[0054] Furthermore, on the base end side of the opening / closing body 20, which is closer to the supporting rib 35, a pair of guide ribs 36, 36 extending in parallel to each other are provided, and on the outside of the pair of guide ribs 36, 36, a pair of supporting ribs 37, 37 extending in parallel to each other are provided.

[0055] The guide protrusion 44a of the locking member 40 (see reference) Figure 5 The device is slidably inserted between a pair of guide ribs 36, 36, guiding the pressing action of the pressing part 63 of the operating member 60 on the pressed part 43. In addition, a pair of support ribs 37, 37 abut against the back side of the base end 45a and the back side of the base end connecting part 44 in the extending direction of the first frame 45 of the locking member 40, supporting the locking member 40.

[0056] like Figure 3 As shown, the cover portion 27 covering the upper opening of the base portion 21 has: a top wall 27a, shaped to match the bottom wall 22 of the base portion 21; and a peripheral wall 27b, which rises from the periphery of the top wall 27a and is disposed outside the peripheral wall 23 of the base portion 21. It should be noted that a cutout 27c is formed in the peripheral wall 27b at a position matching the protruding hole 31 of the base portion 21.

[0057] Furthermore, a pair of limiting portions 7, 7 in a generally L-shaped form are provided on both sides of the top wall 27a in the width direction and at positions that correspond to the pair of openings 24, 24 provided in the base portion 21. In addition, support ribs 35a and a pair of support ribs 37a, 37a are provided on the top wall 27a at positions that correspond to the support ribs 35 and the pair of support ribs 37, 37 of the base portion 21, respectively.

[0058] The support rib 35a supports the surface side of the pressing part 63 and, together with the support rib 35 of the base part 21, stabilizes the pressing action of the pressing part 63. On the other hand, a pair of support ribs 37a, 37a abut against the surface side of the base end 45a in the extending direction of the first frame 45, and support the locking member 40 in a clamping state with the pair of support ribs 37, 37 of the base part 21.

[0059] Next, the locking member 40 will be described in detail.

[0060] As described above, the locking member 40 has a pair of annular portions 41, 41, a connecting portion 42, a pair of legs 50, 50, and a pair of locking protrusions 55, 55.

[0061] In addition, such as Figure 1 , Figure 2 , Figures 4-6 , Figure 8 , Figure 9 As shown, each annular portion 41 has a pair of first frames 45, 45, a pair of second frames 46, 46 and a pair of third frames 47, 47 that are elastically deformable, which are connected to each other and form a continuous annular shape without cracks or gaps.

[0062] like Figure 6 As shown, a pair of first frames 45, 45 are arranged on both sides of the pressing part 63 of the operating member 60, and extend in the opposite direction to the pressing direction F1 of the pressing part 63. It should be noted that the two sides of the pressing part 63 refer to the directions that intersect the pressing direction F1 of the pressing part 63 and the arrangement direction of the pair of annular parts 41, 41.

[0063] The aforementioned pair of first frames 45, 45 have: a pair of first extensions 48, 48 that extend in a straight line obliquely inward in a direction in which the width gradually narrows in the opposite direction to the pressing direction F1 of the pressing part 63; and a pair of second extensions 49, 49 that extend in a straight line obliquely outward from the front end of the extending direction of the pair of first extensions 48, 48 that extends in a direction in which the width gradually widens in the opposite direction to the pressing direction F1 of the pressing part 63.

[0064] It should be noted that the base end of the first extension 48 in the extending direction becomes the base end 45a of the first frame 45 in the extending direction. In addition, the front end of the second extension 49 in the extending direction has an arc shape with rounded corners, and this part becomes the front end 45b of the first frame 45 in the extending direction.

[0065] It should be noted that in the first extension 48, the second extension, the second frame 46, and the third frame 47 constituting the first frame 45, the base end of the extension direction refers to the beginning of the extension direction of each frame, and the front end of the extension direction refers to the end of the extension direction of each frame.

[0066] The connecting portion 42, which connects a pair of annular portions 41, 41 to each other, is connected at two locations at the ends of the pressing portions 63 of the pair of first frames 45, 45 on the pressing direction F1 side. The pressing portions 43 are arranged on the front ends 45b, 45b side of the pair of first frames 45, 45 in the extending direction.

[0067] That is, in this embodiment, the connecting portion 42 is composed of a pressed portion 43 disposed on the front end 45b side of the first frame 45 in the extending direction and a base end side connecting portion 44 disposed on the base end 45a side of the first frame 45 in the extending direction. Furthermore, the base ends of the pair of second extension portions 49, 49 in the extending direction are connected to the pressed portion 43, and the base ends of the pair of first extension portions 48, 48 in the extending direction are connected to the base end side connecting portion 44.

[0068] In addition, the pair of second frames 46, 46 extend in a generally straight line from the front end 45b, 45b side of the pair of first frames 45, 45 toward the direction of separation from each other.

[0069] The front end 46b of each second frame 46 in its extension direction is positioned in a width direction orthogonal to the extension direction of the opening / closing body 20, separated from the front end 46b of the second frame 46 on the opposite side. It should be noted that the base end 46a of each second frame 46 in its extension direction is connected to the front end 45b side of the corresponding first frame 45 in its extension direction.

[0070] Furthermore, the pair of third frames 47, 47 have portions that extend in a straight line at an angle toward each other from the front end 46b, 46b side of the pair of second frames 46, 46 toward the base end 45a, 45a side of the first frames 45, 45 in an approaching manner (hereinafter also referred to as "angled extension portion 47c").

[0071] At the base end of each of these inclined extension portions 47c, 47c, a curved portion is provided that bends along the pressing direction F1 of the pressing portion 63 and extends in a straight line for a predetermined length. These curved portions constitute the base ends 47a, 47a of the third frame 47 in the extension direction.

[0072] Furthermore, the base end 47a of each third frame 47 in its extension direction is connected to the front end 46b of the corresponding second frame 46 in its extension direction. In addition, the front end 47b of each third frame 47 in its extension direction is connected to the base end 45a side of the corresponding first frame 45.

[0073] It should be noted that each annular portion 41 in this embodiment is a roughly pentagonal square annular shape formed by a first frame 45 having two sides composed of a first extension portion 48 and a second extension portion 49, a second frame 46 having one side extending in a straight line, and a third frame 47 having two sides composed of an inclined extension portion 47c and a base end 47a as a curved portion.

[0074] In addition, such as Figure 6 As shown, the thickness of the pair of first frames 45, 45 is greater than the thickness of the pair of second frames 46, 46 and the pair of third frames 47, 47.

[0075] It should be noted that the thickness of each frame 45, 46, and 47 refers to the size of the width direction (the direction of each frame 45, 46, and 47 towards the bottom wall 22 of the base portion 21 and the top wall 27a of the cover portion 27 of the opening and closing body 20) which is orthogonal to the extension direction of each frame 45, 46, and 47.

[0076] Moreover, such as Figure 2 , Figure 5 As shown, a pair of first frames 45, 45, a pair of second frames 46, 46, and a pair of third frames 47, 47 are in the shape of extending in a plate-like form.

[0077] In addition, such as Figure 2 , Figure 5 As shown, in the middle part of the width direction of each plate-shaped frame 45, 46, 47 that intersects (or is orthogonal to) the extension direction, slits 51a, 51b, 51c extending along the extension direction of each plate-shaped frame 45, 46, 47 are formed.

[0078] The first slit 51a extends from the front end 45b side of the first frame 45 in the extending direction to the area near the location of the pressed part 43. Furthermore, the second slit 51b extends from the base end 46a side of the second frame 46 in the extending direction to the front end 46b side.

[0079] Furthermore, the third slit 51c extends from the base end 47a side of the extension direction of the third frame 47 to the front end 47b, and branches from the front end 47b into two, one of which extends to the range reaching the base end side connection portion 44, and the other extends to the range near the part where the pressed portion 43 is located, passing through the base end 45a in the extension direction of the first frame 45.

[0080] Furthermore, in the state before the pressing part 63 presses the pressed part 43, it is preferable that the tilt angle θ of the portion of the third frame 47 that extends obliquely relative to the sliding direction F2 of the locking protrusion 55 is 20° to 55°.

[0081] exist Figure 6 The diagram shows a line segment L parallel to the sliding direction F2 of the locking protrusion 55, but the angle θ of the inclined extension 47c of the third frame 47 relative to the line segment L is preferably 20° to 55°, more preferably 30° to 45°.

[0082] Furthermore, the locking device 10 has a guiding mechanism that guides the connecting part 42 so that it does not deviate in a direction that intersects with the pressing direction F1 of the pressing part 63 when the operating member 60 is operated and the pressing part 63 presses the pressed part 43.

[0083] In this implementation, such as Figure 5 As shown, a guide protrusion 44a is provided on the back side of the connecting portion 44, which constitutes the base end side of the connecting portion 42, and protrudes from the center portion in the width direction. The guide protrusion 44a is slidably inserted between a pair of guide ribs 36, 36 provided on the base portion 21. When the pressing portion 63 presses the pressed portion 43, the connecting portion 42 is guided to not deviate in a direction that intersects with the pressing direction F1 of the pressing portion 63.

[0084] That is, in this embodiment, the guide protrusion 44a of the locking member 40 and the pair of guide ribs 36, 36 of the base portion 21 become the "guide mechanism" in the present invention.

[0085] Furthermore, the base ends 52 of the pair of legs 50 of the locking member 40 are connected to the connecting portions of the front end 46b of the second frame 46 and the base end 47a of the third frame 47, and the extension 53 bends from the base end 52 in a manner orthogonal to the sliding direction F2 of the locking protrusion 55, and extends for a predetermined length in a manner separated from the annular portion 41, forming a generally crank-like shape. It should be noted that the extension 53 of the leg 50 and the annular portion 41 are at different heights.

[0086] Furthermore, the locking protrusions 55 protrude from the front ends of the extensions 53 of each leg 50 along the sliding direction F2. A pair of guide ribs 56, 56 extend from the base end of the locking protrusions 55 on both sides in the width direction orthogonal to the sliding direction F2. These guide ribs 56, 56 lead to a pair of guide grooves 77, 77 of the guide member 70 (see reference). Figure 5 Insertion, the sliding motion of locking protrusion 55 is guided.

[0087] Furthermore, on the outer surface of the locking protrusion 55 at its front end and in the insertion direction of the leg 50 relative to the inner space R of the cylindrical protrusion 25, an inclined portion 57 is formed, which gradually thins towards the front end of the locking protrusion 55. This inclined portion 57 is pressed by the ribs 28a, 28a provided on the base portion 21 when the leg 50 is inserted into the inner space R of the cylindrical protrusion 25.

[0088] It should be noted that the locking member 40 described above is integrally formed by a pair of annular portions 41, 41 including the entire frame (first frame 45, second frame 46, third frame 47), a connecting portion 42, a pair of legs 50, 50 and a pair of locking protrusions 55, 55.

[0089] exist Figure 8The diagram shows the state before the operation member 60 is operated, that is, the state before the pressing part 63 of the operation member 60 is pressed relative to the pressed part 43. Before the pressing part 63 is pressed relative to the pressed part 43, a pair of annular parts 41, 41 are arranged in the opening and closing body 20 in a flexed state that is separated from each other.

[0090] As described above, a pair of annular portions 41, 41 are disposed on the opening and closing body 20 in a flexed state that is separated from each other, thereby applying force to the pair of locking protrusions 55, 55 in the direction of insertion from the insertion holes 30, 75 in such a way that the pair of locking protrusions 55, 55 engage with the pair of locking portions 5, 5.

[0091] It should be noted that the pair of annular portions 41, 41 can also be described as a structure in which a pair of locking protrusions 55, 55 engage with a pair of locking portions 5, 5, and force is applied to the pair of locking protrusions 55, 55 in the direction of insertion from the insertion holes 30, 75.

[0092] The locking member 40 that forms the above structure performs the following actions.

[0093] That is, when from Figure 8 When the operating member 60 is operated in the state shown, and the pressing part 63 slides in the pressing direction F1 to press the pressed part 43 of the locking member 40, as shown... Figure 11 As shown, the movement of the pressing direction F1 of the locking protrusions 55, 55 is restricted by the limiting parts 7, 7, and the pair of first frames 45, 45 elastically deforms via the connecting part 42, along with the pair of second frames 46, 46 and the pair of third frames 47, 47 elastically deforming.

[0094] Specifically, when the pressing force is input from the pressing part 63 of the operating member 60 to the pressed part 43, the pressing force is transmitted from the pressed part 43 to the second extension 49 and the second frame 46 of each first frame 45, and from the pressed part 43 to the first extension 48 and the third frame 47 of each first frame 45.

[0095] Thus, a tensile force G1 is applied to each of the third frames 47 in an inclined direction toward its front end 47b (see reference). Figure 8 The third frame 47 undergoes elastic deformation on one side (refer to...). Figure 9 On one side, the third frame 47 applies a pressing force G2 towards the pressing direction F1 to each locking protrusion 55 (refer to...). Figure 8 ).

[0096] Furthermore, the limiting part 7, which bears the pressing force G2, generates the tensile force G1 and the component force G3 of the pressing force G2 (see reference). Figure 8The force G3 acts on the designated locking protrusion 55, which is pressed towards the locking protrusion 55 on the opposite side.

[0097] Furthermore, due to the tensile force G4 applied to each of the first frames 45 and each of the second frames 46 from the pressed portion 43 (see reference...), Figure 8 Therefore, the first extension 48 of the first frame 45 and the second frame 46 elastically deform on one side (refer to...). Figure 9 ), while applying a tensile force G4 to each locking protrusion 55.

[0098] As described above, the locking protrusion 55 slides (slids) towards the locking protrusion 55 on the opposite side by means of the tensile force G1 from the third frame 47, the component force G3 caused by the pressing force G2, and the tensile force G4 from the first frame 45 and the second frame 46.

[0099] As a result, the pair of locking protrusions 55, 55 slide relative to the pair of locking parts 5, 5 in the separation direction, such as Figure 11 As shown, a pair of locking protrusions 55, 55 disengage from a pair of locking parts 5, 5, and the locking of the opening / closing body 20 relative to the closed state of the opening 3 is released.

[0100] Furthermore, when the operation of the operating member 60 is terminated, the multiple frames 45, 46, and 47 in each annular portion 41 elastically deform as follows: Figure 9 As indicated by arrow G5, the locking protrusions 55, 55 respectively elastically recover, so the pair of locking protrusions 55, 55 slide relative to the pair of locking parts 5, 5 in the approach direction, and the pair of locking protrusions 55, 55 engage with the pair of locking parts 5, 5, locking the opening and closing body 20 in the closed state relative to the opening 3.

[0101] Here, by the elastic recovery of each third frame 47, the pressed part 43 moves in the opposite direction to the pressing direction F1 via the first extension 48 of each first frame 45 to press the pressing part 63, so the operating member 60 returns to the state before the pressing part 63 presses the pressed part 43.

[0102] Furthermore, the configuration is such that, through the elastic recovery of the second extension 49 of each first frame 45 and each second frame 46, a pair of locking protrusions 55, 55 slide in a direction that approaches the pair of locking protrusions 5, 5, that is, the pair of locking protrusions 55, 55 slide in such a way that the pair of locking protrusions 55, 55 return to the state before the pressing part 63 presses the pressed part 43.

[0103] Furthermore, the pair of annular portions 41, 41 are arranged in the opening and closing body 20 in the following manner: (1) before the pressing portion 63 is pressed relative to the pressed portion 43, or (2) after the pressing portion 63 is pressed relative to the pressed portion 43 and each frame 45, 46, 47 elastically deforms and then elastically recovers and returns to the state before the pressing portion 63 presses the pressed portion 43.

[0104] That is, under the above conditions, such as Figure 8 As shown, the locking member 40 is arranged in the opening and closing body 20 such that the front ends 45b, 45b of a pair of first frames 45, 45 are separated from each other, the front ends 46b, 46b of a pair of second frames 46, 46 are separated from each other and the base ends 46a, 46a are separated from each other, and the base ends 47a, 47a of a pair of third frames 47, 47 are separated from each other.

[0105] Furthermore, when the pressing part 63 is pressed relative to the pressed part 43 and each frame 45, 46, 47 elastically deforms, such as Figure 9 As shown, the front ends 45b and 45b of a pair of first frames 45 are close to each other, the front ends 46b and 46b of a pair of second frames 46 are close to each other and the base ends 46a and 46a are close to each other, and the base ends 47a and 47a of a pair of third frames 47 are close to each other.

[0106] Furthermore, the pair of annular portions 41, 41 of the locking member 40 are configured to apply force to the pair of locking protrusions 55, 55 in the direction of insertion from the insertion holes 30, 75 in such a way that the pair of locking protrusions 55, 55 engage with the pair of locking portions 5, 5.

[0107] That is, such as Figure 10 As shown, after pressing the operating member 60, when the pressing operation ends, the frames 45, 46, and 47 of the pair of annular portions 41, 41 elastically recover as described above, and the pair of locking protrusions 55, 55 are pushed out (or force is applied) relative to the pair of locking portions 5, 5 in the engaging direction.

[0108] As a result, a pair of locking protrusions 55, 55 are applied in such a way that they are inserted into the insertion holes 75, 75 of a pair of guide members 70, 70 respectively and also into the insertion holes 30, 30 of a pair of cylindrical protrusions 25, 25 respectively (see reference). Figure 10 ).

[0109] It should be noted that, as Figure 9As shown, even if the operating member 60 is not pushed deeper into the pressed part 43, by pushing the operating member 60 to the extent that each frame 45, 46, 47 can be elastically deformed, when the pressing operation of the operating member 60 ends, a pair of locking protrusions 55, 55 will be forced in the direction of insertion from the insertion holes 30, 75, so that the locking protrusions 55, 55 engage with the locking parts 5, 5.

[0110] That is, in this embodiment, the pair of annular portions 41, 41 serve the same function as the spring member in the locking device of a conventional opening and closing body, which applies force by engaging the locking protrusion with the locking portion.

[0111] Next, refer to Figure 2 , Figure 5 The guide component 70 will be described in detail.

[0112] The guide member 70 of this embodiment has: a pair of sidewall portions 71, 71 disposed on both sides of the leg portion 50 orthogonal to the sliding direction F2 of the locking protrusion 55 and the extension direction of the leg portion 50, and forming a guide portion; and a front wall portion 73 disposed in the direction in which the locking protrusion 55 protrudes relative to the locking portion 5, connecting the pair of sidewall portions 71, 71 to each other, and forming an insertion hole 75. The guide member 70 is a frame-shaped structure with an opening on one side of the extension direction of the leg portion 50 (opposite to the bottom wall portion 74 described below) and an opening on the opposite side of the front wall portion 73.

[0113] Furthermore, one end of the pair of sidewall portions 71, 71 and the front wall portion 73 in the height direction (the end of the front end in the direction of extension toward the leg portion 50) is connected to each other by the bottom wall portion 74 (see reference). Figure 5 It should be noted that in the side wall portion 71, front wall portion 73, etc., "height direction" refers to the direction along the extension direction of the leg portion 50.

[0114] Furthermore, an insertion hole 75 is formed between one end of the pair of sidewall portions 71, 71 in the height direction, one end of the front wall portion 73 in the height direction, and the bottom wall portion 74, for inserting the locking protrusion 55.

[0115] Moreover, such as Figure 5 As shown, on the inner surface (opposing surface) of one end of a pair of sidewall portions 71, 71 in the height direction, grooves 77, 77 are formed in the groove shape extending along the sliding direction F2 of the locking protrusion 55 throughout the entire area from one end to the other in the extending direction of the sidewall portion 71.

[0116] A pair of guide ribs 56, 56 of the locking protrusion 55 are slidably inserted into a pair of guide grooves 77, 77, and the sliding motion of the locking protrusion 55 along the sliding direction F2 is guided.

[0117] Furthermore, a first elastic engagement portion 79 capable of elastic deformation (flexible deformation) is formed on the front wall portion 73 via a pair of slits 79a, 79a. This first elastic engagement portion 79 engages with the dorsal periphery of the insertion hole 30 on the side opposite to the bottom wall 25d, thus preventing the guide member 70 from disengaging from the internal space R of the cylindrical protrusion 25 (see reference). Figure 10 ).

[0118] Furthermore, on the side of the bottom wall portion 74 opposite to the front wall portion 73, a second elastically deformable engaging portion 81 is formed via a pair of cuts 81a, 81a. This second elastically engaging portion 81 engages with the engaging groove 26a of the engaging rib 26 formed in the base portion 21, thus preventing the guide member 70 from detaching from the internal space R of the cylindrical protrusion 25 (see reference). Figure 10 ).

[0119] Furthermore, on the sidewall portion 71 opposite to the bottom wall portion 74, a pair of slits 83a, 83a are respectively formed with elastically deformable anti-slip portions 83. When pressed or otherwise directed towards the rear surface of the leg portion 50, each anti-slip portion 83 engages with the two sides of the rear surface of the leg portion 50 in the width direction, preventing the guide member 70 from falling off the leg portion 50.

[0120] (Modified example) The shape, structure, and layout of the locking part, opening / closing body, locking member, operating member, guide member, and the various parts constituting each member (e.g., the annular part of the locking member, each frame, leg, locking protrusion, etc., and the side wall part, front wall part, elastic engaging part, etc. of the locking device constituting the opening / closing body of the present invention) are not limited to the above-described manner.

[0121] Furthermore, in this embodiment, as described above, it is applicable to a structure in which a lid or other opening / closing body is installed in the opening of the interseat storage compartment in an openable and closable manner. However, it can also be applied, for example, to a structure in which a box-shaped glove box is installed in the opening of the dashboard in an openable and closable manner (in which case, the dashboard becomes the "fixed body" and the glove box becomes the "opening / closing body"). It can also be applied to a structure in which a lid is installed in the opening of the dashboard in an openable and closable manner (in which case, the dashboard becomes the "fixed body" and the lid becomes the "opening / closing body"). It can be widely used for various opening / closing bodies that open and close the opening of a fixed body.

[0122] Furthermore, in this embodiment, the locking part 5 is provided on the side of the fixed body 1, the locking member 40, the operating member 60, and the guiding member 70 are arranged on the side of the opening and closing body 20, and the cylindrical protrusion 25 protrudes from the opening and closing body 20. However, it is also possible, for example, to provide the locking part on the side of the opening and closing body, and to arrange the locking member, the operating member, and the guiding member on the side of the fixed body, so that the cylindrical protrusion protrudes from the fixed body.

[0123] Furthermore, as in this embodiment, when the locking part 5 is provided on the side of the fixed body 1, and the pair of locking protrusions 55, 55 are forced apart by the force applied by the pair of annular parts 41, 41, when the operating member 60 is operated, the pair of locking protrusions 55, 55 slide toward each other against the force applied by the pair of annular parts 41, 41 (see reference). Figure 9 and Figure 11 ).

[0124] However, it can also be configured such that a pair of locking protrusions are forced together by a force applied to a pair of annular portions, moving towards each other. When the operating member is operated, the pair of locking protrusions slide apart against the force applied to the pair of annular portions. Figures 12-14 The second embodiment shown is described in detail.

[0125] Alternatively, a structure could be considered where the locking portion is located on the opening / closing body side (for example, a pair of concave locking portions are provided on both sides of the opening / closing body in the width direction), and a pair of locking protrusions are forced together by the force applied by a pair of annular portions. In such a structure, when the operating member is operated, the pair of locking protrusions will slide apart against the force applied by the pair of annular portions.

[0126] Furthermore, the locking part 5 in this embodiment is hole-shaped, but the locking part may not be hole-shaped, but concave, protruding, frame-shaped, etc. Moreover, the locking part may not be the opening of the fixed body, but may be provided on the opening and closing body.

[0127] Furthermore, in this embodiment, the structure is such that by sliding the operating member 60 in the pressing direction F1, the frames 45, 46, and 47 of the pair of annular portions 41, 41 of the locking member 40 are elastically deformed. However, for example, the operating member can also be a structure that can be rotated to elastically deform the frames of the annular portions of the locking member, as long as the locking protrusion can slide in the direction of engaging / disengaging with the locking portion.

[0128] Furthermore, in this embodiment, each annular portion 41 is a roughly pentagonal square annular shape in which the constituent elements of each frame 45, 46, 46 are generally straight. However, as an annular portion, it may be configured as an annular shape composed only of curved frames such as arcs or bends, or as an annular shape composed of a combination of such curved frames and straight frames. Moreover, as an annular portion, in addition to a roughly pentagonal annular shape, it may also be a roughly triangular, roughly quadrilateral, roughly hexagonal, or polygonal annular shape with more sides.

[0129] Furthermore, in this embodiment, the thickness of the pair of first frames 45, 45 is made thicker than the thickness of the pair of second frames 46, 46 and the pair of third frames 47, 47. However, the thickness of the first frame can also be made thinner than the thickness of the second frame and the third frame, or it can be made with the same thickness as the second frame and the third frame.

[0130] Furthermore, in this embodiment, each frame 45, 46, and 47 is plate-shaped, but each frame 45, 46, and 47 may not be plate-shaped. However, it is preferable that at least one of each frame 45, 46, and 47 is in a plate-shaped extension.

[0131] Furthermore, in this embodiment, slits 51a, 51b, and 51c are formed in each of the frames 45, 46, and 47, respectively, but it is also possible to configure the frames so that no slits are formed in all or part of them.

[0132] Furthermore, in this embodiment, the connecting part 42 is composed of the pressed part 43 and the base end side connecting part 44. However, as a connecting part, it can also be configured to connect a pair of frames only at one part, as long as the pair of opposing first frames can be connected to each other.

[0133] Furthermore, in this embodiment, before the operating member 60 presses the pressed part 43, a pair of annular parts 41, 41 are arranged in the opening and closing body 20 in a flexed state that is separated from each other. However, as a pair of annular parts, they can also be arranged in the fixing body in a flexed state that is close to each other before the operating member is operated (this method will be explained in the second embodiment described later).

[0134] (Effects) Next, the effects of the locking device 10 constructed as described above will be explained.

[0135] Figure 10 This shows the state where the opening 3 of the fixing body 1 is closed by the opening / closing body 20. When the operating member 60 is operated from this state, causing the pressing part 63 to... Figure 8 When the pressing direction F1 is slid, the pressing part 63 presses the pressed part 43 of the locking member 40.

[0136] Thus, as explained in paragraphs 0078-0083, the movement of the pressing direction F1 of the pair of locking protrusions 55, 55 is restricted by a pair of limiting parts 7, 7, and the pair of first frames 45, 45 elastically deforms via the connecting part 42, accompanied by elastic deformation of the pair of second frames 46, 46 and the pair of third frames 47, 47 (see reference). Figure 9 ).

[0137] As a result, the pair of locking protrusions 55, 55 slide relative to the pair of locking parts 5, 5 in the separation direction, such as Figure 11 As shown, a pair of locking protrusions 55, 55 disengage from a pair of locking parts 5, 5, thus releasing the lock of the opening / closing body 20 relative to the closed state of the opening 3, allowing the opening / closing body 20 to be opened from the opening 3 of the fixing body 1.

[0138] Furthermore, when the operation of the operating component 60 is completed, the multiple elastically deformed frames 45, 46, and 47, as... Figure 9 Arrow G5 indicates that they elastically return to their original positions. Thus, with the opening / closing body 20 open from the opening 3 of the fixing body 1, as described in paragraphs 0086 and 0087, the operating member 60 and the pair of locking protrusions 55, 55 return to the state before the pressing part 63 presses the pressed part 43.

[0139] Subsequently, when the opening and closing body 20 is closed relative to the opening 3 of the fixed body 1, the inclined portions 57 and 57 of the pair of locking protrusions 55 and 55 are pressed by the inner periphery of the opening 3 in the width direction, causing the pair of annular portions 41 and 41 to slightly deform elastically, and the pair of locking protrusions 55 and 55 to slide slightly in the direction of approaching each other.

[0140] Furthermore, when the pair of locking protrusions 55, 55 pass through the inner periphery of the opening 3 in the width direction, the pair of annular portions 41, 41 elastically return to their original position, and the pair of locking protrusions 55, 55 slide relative to the pair of locking portions 5, 5 in the approach direction, thereby engaging with the pair of locking protrusions 55, 55. As a result, the opening / closing body 20 can be locked in a closed state relative to the opening 3.

[0141] Furthermore, in this embodiment, the locking member 40 is integrally formed from a pair of annular portions 41, 41 including multiple frames 45, 46, 47 that are elastically deformable, a connecting portion 42, and a locking protrusion 55. When the operating member 60 is operated, the elastic deformation of each frame 45, 46, 47 of each annular portion 41 can return the pair of locking protrusions 55, 55 and the operating member 60 to the state before the operation of the operating member 60, thus reducing the number of parts and simplifying the structure.

[0142] That is, in the locking device described in Patent Document 1, a spring member separate from the drive member is required in order to return the locking lever member to the state before the operation of the operating member. In this locking device 10, such a spring member is not required. As a result, the number of components of the locking device as a whole can be reduced, and the structure of the locking device 10 can be simplified.

[0143] Furthermore, in this embodiment, before the pressing part 63 presses the pressed part 43, a pair of annular parts 41, 41 are disposed on the opening and closing body 20 in a flexed state that is separated from each other.

[0144] According to the above method, in the state before the pressing part 63 presses the pressed part 43, a pair of annular parts 41, 41 are arranged in the opening and closing body 20 in a state of flexing apart from each other. Therefore, after the operation of the operating member 60 when the opening and closing body 20 is opened from the opening 3 of the fixing body 1 is completed, and after the operation of the operating member 60 when the opening and closing body 20 is closed from the opening 3 of the fixing body 1 is completed, the pair of annular parts 41, 41 flex apart from each other.

[0145] As a result, the pair of locking protrusions 55, 55 can reliably return to the state before the pressing of the pressing part 63 relative to the pair of locking parts 5, 5 (the effect of technical solution 2). It should be noted that the same effect can also be obtained when the pair of annular parts are arranged in a flexed state in a close proximity manner on the fixed body or the opening and closing body before the pressing part presses the pressed part.

[0146] Furthermore, in this embodiment, a guiding mechanism (a guide protrusion 44a of the locking member 40 and a pair of guide ribs 36, 36 of the base portion 21) is provided, which guides the member 60 to press the pressed portion 43 when the pressing portion 63 presses the pressed portion 43 by operating the operating member 60, in a manner in which the connecting portion 42 does not deviate in a direction that intersects with the pressing direction F1 of the pressing portion 63.

[0147] According to the above method, by constructing the above-described guiding mechanism, when the operating member 60 is operated and the pressing part 63 presses the pressed part 43, the connecting part 42 is guided in a manner that does not deviate in the direction that intersects with the pressing direction F1 of the pressing part 63. Therefore, the pulling amount of the pair of locking protrusions 55, 55 relative to the pair of locking parts 5, 5 is the same, and the pair of locking protrusions 55, 55 can reliably disengage from the pair of locking parts 5, 5.

[0148] Furthermore, in this embodiment, the connecting portion 42 that connects the pair of annular portions 41, 41 to each other is connected at two locations at the ends of the pressing portions 63 of the pair of first frames 45, 45 on the pressing direction F1 side, and the pressing portion 43 is disposed on the front end 45b, 45b side of the pair of first frames 45, 45 in the extending direction.

[0149] According to the above method, the connecting part 42 has the above configuration. Therefore, when the operating member 60 is operated and the pressing part 63 presses the pressed part 43, the pair of first frames 45, 45 mainly undergo elastic deformation starting from the connecting part with the pressed part 43 (here, the base end of the extension direction of the second extension 49 constituting the first frame 45), which is different from the deformation starting point of the elastic deformation of the pair of third frames 47, 47 (here, the front end 47b of the extension direction of the third frame 47).

[0150] As a result, the deformation initiation points of the pair of first frames 45, 45 and the pair of third frames 47, 47 during elastic deformation can be separated. Therefore, the desired elastic force can be obtained for the pair of first frames 45, 45 and the pair of third frames 47, 47, and the elastic recovery force can be improved.

[0151] Furthermore, the elastic force (or elastic deformation ease, elastic deformation capacity) and elastic recovery force of each frame 45, 46, and 47 can be adjusted by appropriately changing the thickness of each frame 45, 46, and 47. However, there are limits to the adjustment of the elastic force and elastic recovery force of each frame 45, 46, and 47 based on changes in thickness.

[0152] In contrast, in the locking device 10 of this embodiment, at least one of the pair of first frames 45, 45, the pair of second frames 46, 46, and the pair of third frames 47, 47 is in the shape of extending in a plate shape, and a slit extending in the plate shape along the extension direction is formed in the middle part of the plate-shaped frame in the width direction intersecting the extension direction.

[0153] In this embodiment, all frames 45, 46, and 47 are plate-shaped, and slits 51a, 51b, and 51c are formed in each frame 45, 46, and 47, respectively.

[0154] According to the above method, the elastic force and elastic recovery force of the slit frames (in this case, frames 45, 46, and 47) in the plate-shaped frame can be easily adjusted.

[0155] As a result, the desired elastic restoring force is easily obtained for the plate-shaped frame (here, each of the frames 45, 46, and 47), thus enabling the pair of locking protrusions 55, 55 to slide in a stable manner, returning to the state before the pressing part 63 presses the pressed part 43.

[0156] Furthermore, the width of the plate-shaped frame (here, frames 45, 46, and 47) can be easily widened, and when the pressing part 63 presses the pressed part 43 through the operation of the operating member 60, deformation such as torsion can be suppressed for the plate-shaped frame. As a result, the plate-shaped frame can be easily and smoothly elastically restored to the state before the pressing part 63 presses the pressed part 43.

[0157] Furthermore, in this embodiment, the thickness of the pair of first frames 45, 45 is greater than the thickness of the pair of second frames 46, 46 and the pair of third frames 47, 47 (see reference). Figure 5 ).

[0158] According to the above method, the pair of first frames 45, 45 are configured as described above, thereby improving the recovery performance of the locking protrusions 55 based on the pair of first frames 45, 45, which return the pair of locking protrusions 55, 55 to the state before the pressing part 63 presses the pressed part 43. Furthermore, the second frame 46 and the third frame 47, which are thinner than the first frame 45, can be easily elastically deformed, thereby reducing the pressing operation force of the operating member 60.

[0159] Furthermore, in this embodiment, before the pressing part 63 presses the pressed part 43, the tilt angle θ of the inclined extension portion of the third frame 47 relative to the sliding direction F2 of the locking protrusion 55 is 20 to 55°.

[0160] According to the above method, in the state before the pressing part 63 presses the pressed part 43, the tilt angle θ of the third frame 47 relative to the sliding direction F2 of the locking protrusion 55 is 20° to 55°. Therefore, the sliding amount of the locking protrusion 55 can be ensured, and the operating force (operating load) of the operating member 60 can be suppressed from becoming too large.

[0161] (Second embodiment of the locking device for the opening and closing body) Figures 12-14 This illustrates a second embodiment of the locking device for the opening and closing body of the present invention. It should be noted that parts substantially the same as those in the described embodiment are labeled with the same reference numerals, and their descriptions are omitted.

[0162] like Figure 12 As shown, in the case of the locking device of the opening and closing body in this second embodiment, the fixing body 1 has a raised portion 2 disposed between a pair of legs 50, 50 of the locking member 40A. A pair of locking portions 5, 5 are provided on both sides of the raised portion 2 in the width direction.

[0163] Furthermore, the locking member 40A is structured such that its pair of locking protrusions 55, 55 are forced towards each other by the force applied by a pair of annular portions 41, 41. That is, the pair of locking protrusions 55, 55 are pushed out (force is applied) in the direction of engaging with the pair of locking portions 5, 5.

[0164] Moreover, such as Figure 13As shown, the pressed portion 43 of the connecting portion 42 constituting the locking member 40A is disposed on the base end 45a side in the extending direction of the pair of first frames 45, 45. The pressing portion 63 of the operating member 60 is disposed close to the pressed portion 43. It should be noted that, in addition to the pressed portion 43, the connecting portion 42 also has a front end side connecting portion 44b that connects the front ends 45b, 45b sides in the extending direction of the pair of first frames 45, 45.

[0165] In addition, such as Figure 13 As shown, in this embodiment, a pair of limiting portions 7, 7 are configured as side portions of a pair of legs 50, 50 that receive the locking member 40A. Specifically, each limiting portion 7 is configured to receive the side portion of the corresponding leg 50 located on the pressing direction F1 side (towards F1 side) of the pressing portion 63.

[0166] And, when from Figure 13 The state shown is used to operate the operating member 60 so that the pressing part 63 moves towards... Figure 13 When the pressing direction F1 is slid, the pressing part 63 presses the pressed part 43 of the locking member 40. Thus, the movement of the pair of legs 50, 50 in the pressing direction F1 is restricted by a pair of limiting parts 7, 7, and the pair of first frames 45, 45 elastically deforms via the connecting part 42. Accompanying this, the pair of second frames 46, 46 and the pair of third frames 47, 47 elastically deform (see reference). Figure 14 ).

[0167] As a result, the pair of locking protrusions 55, 55 slide relative to the pair of locking parts 5, 5 in the separation direction, the pair of locking protrusions 55, 55 disengage from the pair of locking parts 5, 5, the lock of the opening and closing body 20 relative to the closed state of the opening 3 is released, and the opening and closing body 20 can be opened from the opening 3 of the fixing body 1.

[0168] (Third embodiment of the locking device for the opening and closing body) Figure 15 and Figure 16 This illustrates a third embodiment of the locking device for the opening and closing body of the present invention. It should be noted that parts substantially the same as those in the described embodiment are labeled with the same reference numerals, and their descriptions are omitted.

[0169] The shape of the locking member 40B of the locking device of the opening and closing body in the third embodiment is different from the shape of the locking member 40 in the first embodiment.

[0170] That is, the second extensions 49, 49 are arranged such that the distance between the front ends of the second extensions 49, 49 constituting a pair of first frames 45, 45 in the extension direction is greater than the distance between the front ends of the second extensions 49, 49 in the extension direction in the first embodiment (wider width).

[0171] Furthermore, the pair of second frames 46, 46 extend obliquely toward the pressing direction F1 of the pressing part 63, in a manner that they are separated from each other at the front end 45b, 45b side of the pair of first frames 45, 45 extending in the direction of extension.

[0172] Furthermore, the pair of third frames 47, 47 extend obliquely toward each other from the front end 46b, 46b side of the pair of second frames 46, 46 toward the base end 45a, 45a side of the pair of first frames 45, 45 in the direction of extension.

[0173] Each third frame 47 extends in a generally straight line from the front end 47b to the base end 47a in the extension direction (that is, it does not have a curved portion that bends along the pressing direction F1 of the pressing portion 63 as in the base end 47a of the third frame 47 in the first embodiment), and its base end 47a is connected to the front end 46b in the extension direction of the corresponding second frame 46.

[0174] As a result, each annular portion 41 in the third embodiment is a square annular shape with approximately quadrilateral shape by having a first frame 45 with two sides composed of a first extension portion 48 and a second extension portion 49, a second frame 46 with one side extending in a straight line, and a third frame 47 with one side extending in a straight line.

[0175] Furthermore, a locking protrusion forming portion 54 is provided at the connection portion between the front end 46b of the second frame 46 and the base end 47a of the corresponding third frame 47. Locking protrusions 55 protrude from this locking protrusion forming portion 54. That is, the locking member 40B of this embodiment is configured without the generally crank-shaped leg portion 50 found in the locking members 40 and 40A of the first and second embodiments.

[0176] Furthermore, the locking device with the above-described configuration can achieve the same effect as the locking devices in the first and second embodiments. In addition, the locking member 40B in this third embodiment does not have a leg 50, so the overall height of the locking member 40B can be reduced, resulting in a compact configuration in the height direction. This can reduce the space required for installing the locking member 40B in the opening / closing body and the fixing body, and can achieve thinner walls in the opening / closing body and space-saving in the fixing body.

[0177] It should be noted that the present invention is not limited to the above-described embodiments, and various modified embodiments can be carried out within the scope of the spirit of the present invention, and such embodiments are also included within the scope of the present invention.
