Description

Technical Field

[0001] The present invention relates to a locking device for an opening / closing body, which is used to lock an opening / closing body that is installed in an openable / closable manner at an opening of a fixed body in a closed state. Background Technology

[0002] For example, a cover or other opening / closing element is installed at the opening of a fixed body such as a glove box in an automobile. Furthermore, a locking device is provided between the opening and the opening / closing element, which is configured to lock when the opening / closing element is closed and unlock when the opening / closing element is opened.

[0003] For example, Patent Document 1 describes a locking device comprising: a base member fixed to an outer member; an operating member rotatably supported on the base member; and a rod capable of engaging / disengaging with the locked portion of the fixed member in conjunction with the rotation of the operating member. The operating member comprises: an operating portion exposed on the surface of the outer member; and a shaft support axially supported on the base member. The base member comprises: a hook portion engaging with a mounting edge formed on the outer member; and a locking claw portion engaging with a locking edge formed on the back side of the outer member, thereby restricting the movement of the base member in a direction away from the back side of the outer member.

[0004] The base member has: a pair of opposing wall portions; an arc-shaped shaft support protruding from each wall portion; and a stop portion provided between the pair of wall portions. On the other hand, the operating member has: a long plate-shaped base; an operating portion provided at one end of the base in the longitudinal direction; a pair of side wall portions erected from the side edges of the base along the longitudinal direction; arc-shaped shaft portions respectively provided at each side wall portion; a cylindrical portion erected from the back side of the base, forming a lock cylinder hole for insertion of the lock cylinder; and an anti-rotation portion provided at the top end of the cylindrical portion in the erected direction.

[0005] Furthermore, by positioning a pair of sidewall portions of the operating member outside a pair of wall portions of the base member and inserting a pair of shaft supports into a pair of shaft portions, the operating member is rotatably mounted to the base member. Additionally, when the operating member is rotated to its maximum relative to the base member, the anti-rotation portion of the operating member abuts against the stop portion of the base member, thus limiting further rotation.

[0008] Patent Document 1: WO2017 / 086427 Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] In the case of the locking device in Patent Document 1, when the operating member is rotated to its maximum relative to the base member, the operating force (operating load) of the operating member is transmitted from the anti-rotation part through the cylindrical part with the locking core hole and the base to a pair of sidewall parts, acting on a pair of shaft parts. In this case, in order to improve the breaking strength of the operating member, it is necessary to increase the rigidity of the anti-rotation part, the cylindrical part, the base, and the pair of sidewall parts, but this will lead to an increase in mass, so there is a disadvantage that it is difficult to improve the breaking strength of the operating member.

[0011] Therefore, the object of the present invention is to provide a locking device for an opening and closing body that can improve the destructive strength of the operating member when the operating member rotates to the maximum extent relative to the base member without increasing the rigidity of the operating member.

[0012] Solution for solving the problem

[0013] To achieve the above objectives, the present invention provides a locking device for an opening / closable body that is installed in an openable / closable manner at the opening of a fixed body. The locking device is characterized by comprising: 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, engaging / disengaging with the locking portion; a base member fixed to the other of the fixed body or the opening / closing body; and an operating member rotatably supported on the base member via a rotating portion for operating the locking member. The rotating portion comprises a shaft portion and a shaft support portion, wherein the shaft portion is disposed on one of the operating member or the base member, and the shaft support portion is disposed on the other of the operating member or the base member, supporting the shaft portion for rotatability. The operating member comprises: an operating plate portion extending in a plate shape; and an operating part disposed on the operating plate portion. The base member comprises: one end of the operating plate extending in the direction of extension; an operating load transmission wall portion protruding from the back side of the operating plate portion; a shaft portion or a shaft support portion configured to protrude from both sides of the operating load transmission wall portion toward the outside of the operating member, the shaft support portion being disposed on the operating load transmission wall portion; and a stop portion connected to the operating load transmission wall portion on the side of the operating plate portion closer to the operating member than the shaft portion or the shaft support portion, the base member having: a pair of deformation limiting wall portions disposed on the outside of the portion of the operating load transmission wall portion where the shaft portion or the shaft support portion is located; a shaft support portion or the shaft portion disposed on the pair of deformation limiting wall portions, the shaft portion being configured to protrude from the pair of deformation limiting wall portions toward the operating load transmission wall portion; and a stop receiving portion capable of abutting against the stop portion, thereby limiting the rotation of the operating member.

[0014] Invention Effects

[0015] According to the present invention, when the operating part is operated to rotate the operating member relative to the base member to its maximum extent, the stop part abuts against the stop receiving part to restrict the rotation of the operating member. At this time, since the stop part is connected to the operating load transmission wall part where the shaft part or shaft support part is arranged, the operating load received by the stop part from the stop receiving part is transmitted to the shaft part via the operating load transmission wall part. The portion of the operating load transmission wall part where the shaft part or shaft support part is arranged, the shaft part arranged to protrude from both sides of the operating load transmission wall part, or the shaft support part arranged in the operating load transmission wall part is intended to deform in a way that expands outward of the operating member, but this deformation is restricted by a pair of deformation limiting walls. As a result, the breaking strength (difficulty of breaking the operating member) of the operating member can be improved without increasing the rigidity of the operating member.

[0041] (First embodiment of the locking device for the opening and closing body)

[0042] Hereinafter, with reference to the accompanying drawings, a first embodiment of the locking device for the opening and closing body of the present invention will be described.

[0043] like Figure 1 As shown, the locking device 10 (hereinafter referred to as "locking device 10") of the opening and closing body in this embodiment is, for example, a device for locking the opening and closing of the opening 1a of the fixed body 1 such as the dashboard of a vehicle, or the opening and closing body 2 such as the glove box, which is installed in an openable and closable manner.

[0044] The locking device 10 of this embodiment mainly consists of the following structure: a pair of locking parts 1b, 1b, provided in the opening 1a of the fixed body 1; a pair of locking members 20, 20, disposed in the opening and closing body 2, engaging / disengaging with the pair of locking parts 1b, 1b; a rotating member 25, rotatably supported on the opening and closing body 2, causing the pair of locking members 20, 20 to slide in conjunction; a force-applying unit (torsion spring 27), applying force to the pair of locking members 20, 20 in the direction of engaging with the pair of locking parts 1b, 1b; a base member 30, fixed to the opening and closing body 2; and an operating member 50, rotatably supported on the base member 30 via a rotating part, operating the pair of locking members 20, 20. It should be noted that in this embodiment, the locking parts 1b, 1b, which are perforated, are provided on the inner surfaces of both sides of the opening 1a of the fixed body 1 in the width direction. Furthermore, the rotating part in this embodiment includes: a shaft 61 provided on the operating member 50; and a shaft support 37 provided on the base member 30, which supports the shaft 61 so that it can rotate.

[0045] like Figure 2 , Figure 3 As shown, the operating member 50 includes: an operating plate portion 51 extending in a plate shape for a predetermined length; an operating portion 52 provided at one end of the operating plate portion 51 in the extending direction; an operating load transmission wall portion 57 (hereinafter also referred to as "transmission wall portion 57") protruding from the back side of the operating plate portion 51; the aforementioned shaft portions 61, 61, configured to protrude from both sides of the transmission wall portion 57 toward the outside of the operating member 50; and a stop portion 63 connected to the transmission wall portion 57 on the side of the shaft portion 61 closer to the operating portion 52. It should be noted that, in this invention, the connection between the stop portion 63 and the transmission wall portion 57 means that the stop portion 63 and the transmission wall portion 57 are directly connected and integrally formed.

[0046] In addition, such as Figure 2 , Figure 5As shown, the base member 30 has: a pair of deformation limiting walls 35, 35 (hereinafter also referred to as "limiting walls 35"), disposed on the outside of the portion of the transmission wall 57 provided with the shaft portion 61; the aforementioned shaft support portions 37, 37, formed on the pair of limiting walls 35, 35, supporting the shaft portions 61, 61 so as to be rotatable; and a stop receiving portion 41, which can abut against the stop portion 63 to limit the rotation of the operating member 50.

[0047] like Figure 1 As shown, in this embodiment, locking portions 1b, 1b in the form of holes are provided on the inner surfaces of both sides of the opening 1a of the fixing body 1 in the width direction. Furthermore, as... Figure 1 As shown, the opening / closing body 2 of this embodiment includes: an outer member 3 disposed inside the carriage; and an inner member 4 disposed on the back side of the outer member 3. A rectangular receiving recess 5 with a laterally elongated shape is formed on one side of the outer member 3 in the width direction and above it. The base member 30 and the operating member 50 are received in the receiving recess 5 (see reference). Figure 6 Furthermore, an elongated mounting hole 6 is formed at the bottom 5a of the receiving recess 5.

[0048] The base member 30 is mounted from the surface side of the mounting hole 6. It should be noted that "surface side" or "surface side" as used here refers to the side or surface facing the opening direction of the opening / closing mechanism, starting from the opening of the fixture such as a vehicle. It should also be noted that, in the case of a fixture installed in a vehicle, the side facing the interior space of the vehicle may be designated as the "surface side" or "surface side". Furthermore, "back side" or "back face side" refers to the side opposite to the "surface side" or "surface side", that is, the side or surface facing the closing direction of the opening / closing mechanism. It should be noted that not only for the mounting hole, but also for other components described below (base member 30, operating member 50, etc.), "surface side", "back side", and "back face side" have the same meaning.

[0049] like Figure 1 As shown, the inner component 4 is generally box-shaped with an opening at the top. Furthermore, a horizontally elongated locking recess 4a is provided on the surface side (front side) of the inner component 4 opposite to the outer component 3, and on its upper portion. This locking recess 4a allows the pair of locking members 20 to slide. Locking through holes 4b and 4b are formed on both sides of the locking recess 4a along its longitudinal direction. Additionally, a rotating member support 7 for rotatably supporting the rotating member 25 protrudes from the surface side of the bottom surface of the locking recess 4a.

[0050] In addition, such as Figure 1 , Figure 10As shown, in this embodiment, the pair of locking members 20, 20 are identical in shape. The base end 21 of the locking member 20 is bent into a crank shape and extends in a straight line toward the top end. The top end 22 of the locking member 20 engages / disengages with the locking part 1b (see reference). Figure 10 , Figure 11 Each locking member 20 has a frame-shaped part 23 in the shape of a quadrilateral frame on the top part 22 side.

[0051] The rotating member 25 has a generally rhomboid shape with a long axis (see reference). Figure 10 The rotating member 25 has its long-length middle portion rotatably supported on the rotating member support 7, and its two long-length ends connected to the base ends 21, 21 of a pair of locking members 20, 20. The rotating member 25 rotates in a predetermined direction, thereby causing the pair of locking members 20, 20 to slide synchronously via the rotating member 25. Furthermore, a torsion spring 27 is mounted on the rotating member 25, such as... Figure 10 As indicated by arrow A, the rotating member 25 is subjected to rotational force, thereby causing the top ends 22, 22 of the pair of locking members 20, 20 to engage with the pair of locking parts 1b, 1b. Figure 10 Force is applied in the direction of arrow B. It should be noted that the top ends 22, 22 of a pair of locking members 20, 20 protrude from the locking through holes 4b, 4b provided in the locking configuration recess 4a.

[0052] Next, refer to Figure 2 as well as Figures 5-8 The base component 30 will be described in detail.

[0053] The base member 30 of this embodiment is composed of the following structure: a bottom wall 31, which is a long plate that is long in one direction; a pair of side wall portions 32, 32, which are erected from both sides along the long side of the bottom wall 31 and extend along the extension direction of the bottom wall 31; a connecting wall 33, which is disposed at one end of the bottom wall 31 in the longitudinal direction and connects the pair of side wall portions 32, 32 to each other; and a connecting wall 34, which is disposed at the other end of the bottom wall 31 in the longitudinal direction and connects the pair of side wall portions 32, 32 to each other. The base member 30 is a generally long box-shaped structure with an opening at the top (above) side opposite to the bottom wall 31.

[0054] It should be noted that in the following description, the extension direction of the bottom wall 31 is defined as "extension direction X1", and the direction orthogonal to the extension direction X1 is defined as "width direction Y1" (the same meaning applies to the base member 30 itself and to all parts other than the bottom wall 31 constituting the base member 30).

[0055] A sliding groove 31a is formed in the bottom wall 31, and the sliding groove 31a holds the working rod 65 of the operating member 50 (see reference). Figure 3It can be slidably moved to receive. In addition, protruding tabs 35a, 35a in a generally trapezoidal shape are provided above the pair of side wall portions 32, 32 (on the side opposite to the bottom wall 31) and near the connecting wall 34.

[0056] Moreover, such as Figure 2 As shown, the portion of one end of a pair of sidewall portions 32, 32 including the tab 35a, near the other end in the extending direction X1, forms a pair of limiting walls 35, 35. These limiting walls 35, 35 are configured to face the outer side of the portion of the transfer wall 57 having a shaft portion 61 (here, the portion of the pair of flat surfaces 57b, 57b of the transfer wall 57 described later with shaft portions 61, 61), thus limiting deformation of the transfer wall 57. It should be noted that the inner surfaces (opposing surfaces) of the pair of limiting walls 35, 35 are formed to be parallel to each other.

[0057] Furthermore, a circular hole-shaped shaft support portion 37 is formed through the protrusions 35a, 35a constituting a pair of limiting wall portions 35, 35. Moreover, as... Figure 7 , Figure 8 As shown, each shaft portion 61 of the operating member 50 is inserted from the inside of each shaft support portion 37, thereby the operating member 50 is rotatably supported on the base member 30.

[0058] Furthermore, on the outer surface of each sidewall portion 32 and the bottom wall 31 side, there are: a flexible elastic engaging piece 38 formed via a "ko"-shaped slit 38a; and a rib 39 protruding from a position adjacent to the elastic engaging piece 38. The elastic engaging piece 38 engages with the back periphery of the mounting hole 6, and the rib 39 engages with the front periphery of the mounting hole 6 (see reference). Figure 7 ).

[0059] Furthermore, a pair of hooks 40, 40 protrude from both sides of the bottom wall 31 side of the connecting wall 33 in the width direction Y1, engaging with the back periphery of the mounting hole 6. Moreover, a notch 41a is formed in the middle of the connecting wall 33 in the width direction Y1, cut from the bottom wall 31 towards the top opening, and a stop receiving portion 41 is provided on the side of the connecting wall 33 opposite to the bottom wall 31 side via this notch 41a. Furthermore, as... Figure 9 As shown, when the operating part 52 of the operating member 50 is rotated to its maximum relative to the base member 30 in a direction away from the base member 30 and the bottom 5a of the receiving recess 5, the stop part 63 abuts against the stop receiving part 41, and further rotation of the operating member 50 is restricted.

[0060] Furthermore, a pair of elastic engaging claws 42, 42 are provided on both sides of the bottom wall 31 side of the connecting wall 34 in the width direction Y1, engaging with the back periphery of the mounting hole 6. Moreover, a rubber damper 43 is fitted at the corner of one end side in the extension direction X1 of the base member 30, thereby reducing the impact noise when the operating part 52 of the operating member 50 rotates towards the bottom 5a of the receiving recess 5. Additionally, a coil spring 44 is provided at the corner of the other end side in the extension direction X1 of the base member 30.

[0061] Next, refer to Figures 2-8 The operating component 50 will be described in detail.

[0062] The operating member 50 of this embodiment is generally elongated in one direction and has an operating plate portion 51 that extends in a plate shape for a predetermined length. It should be noted that in the following description, the extending direction of the operating plate portion 51 is defined as the "extending direction X2", and the direction orthogonal to the extending direction X2 is defined as the "width direction Y2" (the same meaning applies to the operating member 50 itself, the parts other than the operating plate portion 51 constituting the operating member 50, and the cover member 70 described further later).

[0063] An operating portion 52 is provided at one end (top portion) of the operating plate portion 51 extending in the X2 direction. This operating portion 52 serves as the part that the operator holds to operate the operating member 50 when rotating it. Furthermore, the other end of the operating plate portion 51 extending in the X2 direction becomes the base end portion 53 of a pair of shaft support portions 37, 37 rotatably supported on the base member 30. Moreover, a circular lock cylinder insertion hole 51a is formed at the other end of the operating plate portion 51 extending in the X2 direction for the lock cylinder 67 to pass through. Additionally, a generally cylindrical damper abutment portion 51b is provided on the back side of the operating plate portion 51 (the side opposite the base member 30) near one end extending in the X2 direction, for abutting against the damper 43.

[0064] Furthermore, a pair of sidewalls 55, 55 extending in the extension direction X2 of the operation plate portion 51 are erected from both sides of the operation plate portion 51 toward the back side (towards the base member 30). In addition, recesses 59, 59 for receiving a pair of protrusions 35a, 35a of the base member 30 are formed at the other end of the pair of sidewalls 55, 55 in the extension direction X2.

[0065] Furthermore, a generally cylindrical transmission wall portion 57, capable of inserting the lock cylinder 67, is provided erected on the back side of the operation panel portion 51 and at the periphery of the back side of the lock cylinder insertion hole 51a. This transmission wall portion 57 will be described in detail later, but... Figure 8As shown, it serves to transmit the operating load input via the stop part 63 to a pair of shaft parts 61, 61 (see reference). Figure 8 (arrow F2′), thus enabling radial outward and radial inward flexural deformation. It should be noted that the aforementioned operating load in the transmission wall 57 is primarily located in the semicircular portion 57a ​​(refer to...) situated on the side closer to the operating portion 52 than the pair of shaft portions 61, 61. Figure 8 )transfer.

[0066] Furthermore, on the outer periphery of the two circumferentially opposite sides (two sides in the width direction Y2) of the transfer wall portion 57, and at positions matching the pair of recesses 59, 59, parallel, flat surfaces 57b, 57b are formed. From these two flat surfaces 57b, 57b near the operation plate portion 51 (at the base end side in the upright setting direction of the transfer wall portion 57), a pair of shaft portions 61, 61 are coaxially protruding.

[0067] Furthermore, such as Figure 4 As shown, when viewing the operating member 50 from the rear side (when viewed from the rear view), a pair of shaft portions 61, 61 extend from the other end (near the base end 53) in the extension direction X2 of the operating member 50 relative to the axis C of the transfer wall portion 57, and are connected to the transfer wall portion 57. Furthermore, as... Figure 3 As shown, a tapered surface 61a is formed at the top end of each shaft portion 61. The tapered surface 61a is obliquely cut from the base end side of the transmission wall portion 57 in the standing direction toward the top end side in the standing direction, making it easier to insert the shaft portion 61 into the inside of the shaft support portion 37.

[0068] Additionally, when assembling the operating member 50 onto the base member 30, a pair of shaft portions 61, 61 of the operating member 50 are inserted between a pair of protrusions 35a, 35a of the base member 30, pressing the operating member 50 into the base member 30. Then, the pair of shaft portions 61, 61 are inserted from the inside into a pair of shaft support portions 37, 37 of the base member 30 (see reference). Figure 7 , Figure 8 This allows the operating member 50 to be rotatably supported on the base member 30. As a result, a pair of limiting wall portions 35, 35 of the base member 30 are positioned opposite each other on the outer sides of a pair of flat surfaces 57b, 57b (see reference). Figure 7 , Figure 8In particular, the tabs 35a, 35a constituting the pair of limiting wall portions 35, 35 are disposed on the outer side of the portion of the pair of flat surfaces 57b, 57b that has the pair of shaft portions 61, 61. It should be noted that the pair of flat surfaces 57b, 57b and the inner surfaces of the pair of limiting wall portions 35, 35 including the tabs 35a, 35a are all flat surfaces. Therefore, the flat surface 57b and the inner surface of the limiting wall portion 35 are disposed opposite each other in a close position, and the gap between the flat surface 57b and the inner surface of the limiting wall portion 35 is reduced. Moreover, as Figure 6 , Figure 9 As shown, the operating member 50 rotates relative to the base member 30 with a pair of shafts 61, 61 as pivot points, such that the operating portion 52 of the operating plate portion 51 of the operating member 50 approaches or moves away from the base member 30 and the bottom 5a of the receiving recess 5 is close to or away from the base member 30.

[0069] In addition, such as Figure 6 As shown, the helical spring 44 is clamped in a compressed state between the other end of the operating member 50 extending in the X2 direction and the other end of the base member 30 extending in the X1 direction. Therefore, as Figure 9 As shown, when the operating member 50 is rotated relative to the base member 30 such that the operating part 52 of the operating plate part 51 of the operating member 50 is away from the base member 30 and the bottom 5a of the recess 5 is accommodated, when the operator's hand is removed from the operating part 52, a rotational force is applied to the operating part 52 in the direction of approaching the base member 30 and the bottom 5a of the recess 5.

[0070] Furthermore, such as Figure 3 As shown, a stop portion 63 is provided protruding from the top end of the transfer wall portion 57 in the upright setting direction and from the outer surface of the pair of shaft portions 61, 61 on the side closer to the operating part 52. This stop portion 63 is orthogonally arranged to the pair of shaft portions 61, 61 and connected to the transfer wall portion 57. That is, the transfer wall portion 57, the pair of shaft portions 61, 61, and the stop portion 63 are integrally and continuously formed. Furthermore, as... Figure 9 As shown, when the operating member 50 is rotated to its maximum relative to the base member 30 with the operating portion 52 of the operating member 50 moving away from the base member 30 and the bottom 5a of the receiving recess 5, the stop portion 63 abuts against the stop receiving portion 41 to limit further rotation of the operating member 50.

[0071] In addition, such as Figure 3As shown, a working lever 65 is erected on the back side of the other end side extending in the X2 direction from the operating plate portion 51. A portion of the working lever 65 is connected to the portion of the transmission wall portion 57 that is circumferentially opposite to the portion where the stop portion 63 is provided, and the working lever 65 is erected higher than the top end of the transmission wall portion 57 in the erection direction. Furthermore, the working lever 65 extends out from the back side of the sliding groove 31a of the base member 30 and enters the frame-shaped portion 23 of one of the locking members 20. Moreover, when the operating portion 52 of the operating member 50 is rotated in a direction away from the bottom 5a of the receiving recess 5 of the base member 30, the working lever 65 presses against the frame-shaped portion 23 of one of the locking members 20. Therefore, via the rotating member 25, the top ends 22, 22 of the pair of locking members 20, 20 slide in a direction that does not engage with the pair of locking portions 1b, 1b of the fixing body 1 (see reference). Figure 11 ).

[0072] Furthermore, in this locking device 10, it is configured such that when the operating part 52 rotates the operating member 50 relative to the base member 30 and the stop part 63 abuts against the stop receiving part 41, the operating load from the stop receiving part 41 is input to the stop part 63, and the operating load is transmitted from the stop part 63 to the transmission wall part 57, and then transmitted to the shaft part 61 via the transmission wall part 57.

[0073] That is, from Figure 6 From the state shown, the operating part 52 of the operating member 50, as indicated by arrow F1, is rotated to its maximum extent relative to the base member 30 in a direction that moves away from the bottom 5a of the receiving recess 5, as shown in the figure. Figure 9 As shown, the stop portion 63 abuts against the stop receiving portion 41, restricting further rotation of the operating member 50. Thus, the stop portion 63 receives the operating load F1′ from the stop receiving portion 41. That is, the operating load F1′ is input from the stop receiving portion 41 to the stop portion 63, and therefore the operating load F1′ is transmitted from the stop portion 63 to the transmission wall portion 57.

[0074] Therefore, the aforementioned operating load F1′ originates from the circumferential center of the semicircular portion 57a ​​of the transmission wall portion 57, where the stop portion 63 is located, specifically the portion of the transmission wall portion 57 that is closer to the operating portion 52 than the pair of shaft portions 61, 61. Figure 9 Arrow F2 indicates the transmission towards the axial base end of the semicircular portion 57a, and as... Figure 8 Arrow F2′ indicates that the load is transmitted circumferentially to both ends of the semicircular portion 57a. As a result, the aforementioned operating load F1′ is applied to the portion of the transmission wall 57 provided with shaft portions 61, 61, that is, the portion of the pair of flat surfaces 57b, 57b of the transmission wall 57 provided with a pair of shaft portions 61, 61. Thus, as... Figure 8As indicated by arrow F3, a pair of flat surfaces 57b, 57b are to flex and deform in a manner that expands in a direction away from each other (or, in other words, a pair of flat surfaces 57b, 57b are to flex and deform radially outward toward the transmission wall portion 57 in a manner that expands at intervals between the base ends of a pair of shaft portions 61, 61; further, it can also be said that a pair of shaft portions 61, 61 are to flex and deform radially outward toward the transmission wall portion 57).

[0075] At this time, a pair of limiting walls 35, 35 are disposed opposite each other on the outer sides of the pair of flat surfaces 57b, 57b. In particular, a pair of protrusions 35a, 35a constituting the pair of limiting walls 35, 35 are disposed opposite each other on the outer sides of the portions of the pair of flat surfaces 57b, 57b provided with the pair of shaft portions 61, 61. Therefore, the radial outward flexural deformation of the portions of the pair of flat surfaces 57b, 57b provided with the pair of shaft portions 61, 61 towards the transmission wall 57 is limited. It should be noted that in this embodiment, the lock cylinder 67 is inserted and disposed inside the transmission wall 57, thereby limiting the radial inward flexural deformation of the transmission wall 57.

[0076] (Modified Example)

[0077] The shape, structure, and layout of the locking part, locking member, base member, operating member, and the various parts constituting the operating member (operating plate part, operating load transmission wall part, shaft part, stop part, etc.) and the various parts constituting the base member (deformation limiting wall part, shaft support part, stop receiving part, etc.) of the locking device constituting the opening and closing body in this invention are not limited to the above-described scheme.

[0078] Furthermore, in this embodiment, as described above, it is applicable, for example, to a structure in which a box-shaped glove box is rotatably mounted on the opening of the dashboard (in which case the dashboard becomes a "fixed body" and the glove box becomes an "opening and closing body"), but it can also be applied to a structure in which a cover is mounted on the opening of the dashboard in an openable and closable manner (in which case the dashboard becomes a "fixed body" and the cover becomes an "opening and closing body"), and can be widely used for various opening and closing bodies that open and close the opening of a fixed body.

[0079] Furthermore, in this embodiment, the mounting hole 6 is formed on the opening and closing body 2, and the locking member 20 is slidably disposed on the opening and closing body 2. However, it is also possible to form the mounting hole on the fixed body and slidably dispose the locking member on the side of the fixed body.

[0080] Furthermore, the locking part 1b in this embodiment is hole-shaped, but the locking part may not be hole-shaped, but concave, protruding, frame-shaped, etc. In addition, the locking part may be provided in the opening and closing body, rather than in the opening of the fixed body.

[0081] Furthermore, in this embodiment, the torsion spring 27, which serves as a force-applying unit, applies rotational force to the rotating member 25, thereby applying force to the locking member 20 connected to the rotating member 25 in the direction of engaging with the locking part 1b (see reference). Figure 10 However, as a force-applying unit that applies force to the locking member in the direction of engaging with the locking part, it may be, for example, a tension spring that pulls one side of the locking member toward the locking part.

[0082] Furthermore, in this embodiment, when the operating member 50 is rotated as described above, one locking member 20 slides, and the other locking member 20 slides via the rotating member 25. However, it can also be configured such that the rotating member is rotated by the rotation operation of the operating member, thereby causing a pair of locking members to slide.

[0083] Furthermore, the opening and closing body 2 in this embodiment is composed of an outer component 3 and an inner component 4, but it can also be composed of a single sheet of material.

[0084] Furthermore, the shaft support portion 37 formed on the base member 30 is in the shape of a circular hole, but as a shaft support portion, for example, it may also be provided as a groove in the shape of an arc (which will be explained in the embodiments described later) or a protrusion in the shape of an arc.

[0085] Furthermore, in this embodiment, the pair of shaft portions 61, 61 are connected to the transmission wall portion 57, but the shaft portions may also be separate from the operating load transmission wall portion (this will be explained in the embodiments described later). It should be noted that the shaft portion has a shape suitable for the shape of the shaft support portion. For example, if the shaft support portion is an arc-shaped groove as described above, the shaft portion is preferably an arc-shaped protrusion.

[0086] Furthermore, in this embodiment, a lock cylinder 67 is inserted and disposed inside the transmission wall 57, and the radially inward flexural deformation of the transmission wall 57 is restricted. However, it can also be configured such that a lock cylinder is not inserted into the operating load transmission wall, or that other components different from the lock cylinder are inserted and disposed in the operating load transmission wall (this will be explained in the embodiments described later).

[0087] Furthermore, in this embodiment, the rotating part that allows the operating member 50 to be rotatably supported on the base member 30 is composed of a shaft portion 61 provided on the operating member 50 and a shaft support portion 37 provided on the base member 30. However, the rotating part may also be composed of a shaft portion provided on the base member and a shaft support portion provided on the operating member.

[0088] In this case, the shaft support portion is disposed on the operating load transmission wall portion constituting the operating member, and the stop portion constituting the operating member is connected to the operating load transmission wall portion on the operating part side, closer to the shaft support portion than the operating part. On the other hand, the shaft portion is configured to protrude from a pair of deformation limiting wall portions constituting the base member toward the operating load transmission wall portion. That is, the shaft portion is configured to protrude from a pair of deformation limiting wall portions toward the inside of the base member toward the operating load transmission wall portion disposed inside the pair of deformation limiting wall portions.

[0089] Furthermore, the transfer wall 57 in this embodiment is generally cylindrical, but as an operating load transfer wall, it may also be semi-cylindrical, triangular, V-shaped, U-shaped, etc.

[0090] exist Figure 12 The present invention describes a modified example of an operating load transfer wall 68 (hereinafter referred to simply as "transfer wall 68"). This transfer wall 68 is a frame-shaped structure consisting of: a pair of inclined ribs 68a, 68a extending outward at one end from the extending direction X2 of the operating member 50A toward the other end; curved ribs 68b, 68b formed at the top ends of the pair of inclined ribs 68a, 68a extending along the extending direction X2 of the operating member 50A; a first connecting rib 68c connecting the curved ribs 68b, 68b to each other extending along the width direction Y2 of the operating member 50A; and a second connecting rib 68d extending from the base ends of the pair of inclined ribs 68a, 68a along the extending direction X2 of the operating member 50A and connecting with the center of the extending direction of the first connecting rib 68c. In addition, a stop portion 63 is provided at the base end of the pair of inclined ribs 68a, 68a and the second connecting rib 68d in the extending direction, and shaft portions 61, 61 protrude from the outer surface of the curved ribs 68b, 68b.

[0091] In the case of such a transfer wall 68, when the operating load input from the stop receiving part 41 to the stop part 63 is transferred from the stop part 63 to the transfer wall 68, the operating load is transferred in a pair of inclined ribs 68a, 68a (see reference). Figure 12 Arrow F2′ acts on a pair of curved ribs 68b, 68b, causing the pair of curved ribs 68b, 68b to flex and deform in a manner that expands away from each other (see reference). Figure 12 (arrow F3). However, in this case, the radially outward flexural deformation of the pair of curved ribs 68b, 68b is also limited by configuring a pair of deformation-limiting walls (not shown) on the outer side of the pair of curved ribs 68b, 68b.

[0092] (Effects)

[0093] Next, the effects of the locking device 10 constructed with the above structure will be explained.

[0094] In this locking device 10, when the opening and closing body 2 is closed from the opening 1a of the fixing body 1, the top ends 22, 22 of a pair of locking members 20, 20 are engaged with the locking portions 1b, 1b of the fixing body 1 (see reference). Figure 10 Thus, the opening and closing body 2 is locked in the closed state.

[0095] From that state onwards, as Figure 9 As shown, when the operating part 52 of the operating member 50 is rotated in a direction away from the base member 30 and the bottom 5a of the receiving recess 5, as Figure 11 As shown, the top end 22 of one locking member 20 is pulled from the locking part 1b toward the non-locking direction by resisting the rotational force applied by the rotating member 25, and in conjunction with this, the top end 22 of the other locking member 20 is pulled from the locking part 1b toward the non-locking direction via the rotating member 25. Therefore, the locking state of the opening and closing body 2 can be released, and the opening and closing body 2 can be opened from the opening 1a of the fixing body 1.

[0096] Furthermore, in this locking device 10, as described above, when the operating part 52 of the operating member 50 is held and the operating part 52 is rotated to its maximum relative to the base member 30, the stop part 63 abuts against the stop receiving part 41, and the operating load F1′ is input from the stop receiving part 41 to the stop part 63, and the operating load F1′ is transmitted from the stop part 63 to the transmission wall part 57 (see reference). Figure 9 Therefore, as described above, the operating load F1′ is transmitted in the semicircular portion 57a ​​of the transmission wall 57 (see reference). Figure 8 Arrow F2′ is assigned to a pair of flat surfaces 57b, 57b, as shown below. Figure 8 As indicated by arrow F3, the portions of a pair of flat surfaces 57b, 57b with a pair of shaft portions 61, 61 are intended to flex and deform in a direction that expands away from each other. At this time, a pair of limiting walls 35, 35 (in this case, a pair of protrusions 35a, 35a) are arranged opposite each other on the outer sides of the pair of flat surfaces 57b, 57b. Therefore, the flexural deformation of the portions of the pair of flat surfaces 57b, 57b with a pair of shaft portions 61, 61, and the pair of shaft portions 61, 61, directed radially outward from the transmitting walls 57, can be limited. As a result, the breaking strength (difficulty of breaking the operating member 50) of the operating member 50 can be increased without increasing its rigidity.

[0097] Furthermore, in this embodiment, the transmission wall 57 is cylindrical in shape, allowing the lock cylinder 67 to be inserted.

[0098] According to this design, before the lock cylinder 67 is inserted into the transmission wall portion 57, the transmission wall portion 57 can easily deform radially inward. Therefore, when the transmission wall portion 57 is arranged between a pair of limiting walls 35, 35 of the base member 30 for assembling the operating member 50 onto the base member 30, it is easy to arrange the transmission wall portion 57 and support the shaft portion 61 on the shaft support portion 37, thereby improving the assembly operability of the operating member 50 relative to the base member 30. Furthermore, when the lock cylinder 67 is inserted into the transmission wall portion 57 with the shaft portion 61 supported on the shaft support portion 37, the radially inward deformation of the transmission wall portion 57 can be restricted, thereby improving the rigidity of the transmission wall portion 57 itself, the shaft portion 61 provided on the transmission wall portion 57, and the stop portion 63.

[0099] (Second embodiment of the locking device for the opening and closing body)

[0100] exist Figures 13-18 The second embodiment of the locking device for the opening and closing body of the present invention is shown. It should be noted that parts that are substantially the same as those in the above embodiment are labeled with the same reference numerals and their descriptions are omitted.

[0101] In the locking device 10B of the opening and closing body in this embodiment (hereinafter referred to as "locking device 10B"), a pair of notches 59B, 59B are formed on both sides of the operating plate portion 51 along the extending direction X2 for a pair of restricting wall portions 35, 35 to enter. The operating member 50B also has a cover member 70 disposed on the surface of the operating plate portion 51, and the cover member 70 is provided with wall portions 75, 75 covering the pair of notches 59B, 59B.

[0102] like Figure 14 As shown, in the operating member 50B, a pair of notches 59B, 59B extending along the extending direction X2 of the operating plate portion 51 are formed by cutting along both sides of the base end portion 53 side of the operating plate portion 51 in the width direction Y2. These notches 59B, 59B are configured to allow a pair of protrusions 35a, 35a of the base member 30 to enter (see reference). Figure 17 Furthermore, the pair of shaft portions 61, 61 protruding from a pair of flat surfaces 57b, 57b of the transmission wall portion 57 are arc-shaped protrusions. It should be noted that the pair of shaft support portions 37, 37 provided on the base member 30 side are arc-shaped grooves.

[0103] On the other hand, such as Figure 15As shown, the cover member 70 has a cover plate portion 71, which is a generally long plate extending in a plate shape for a predetermined length to be adapted to the operation plate portion 51. A pair of wall portions 75, 75 extending along the extension direction X2 of the cover plate portion 71 are erected from both sides of the width direction of the cover plate portion 71 toward the back side (towards the operation member 50B side). In addition, a pair of locking protrusions 73a, 73a are formed on the base end portion 73 side of the extension direction X2 of the cover plate portion 71 for locking with both sides of the base end portion 53 of the operation plate portion 51 in the width direction. It should be noted that the operation portion 72 is formed on the top end portion side of the extension direction X2 of the cover plate portion 71. Moreover, a (see reference) is provided on the side of the cover plate portion 71 near the base end portion 73 of the operation portion 72 for the top end portion 52B of the operation plate portion 51 to enter and lock. Figure 16 ) 72a, the locking frame.

[0104] Furthermore, the top end portion 52B of the operating plate portion 51 is inserted into and locked into the locking frame portion 72a of the cover portion 71, and the locking protrusions 73a, 73a of the cover portion 71 are locked into the width-direction sides of the base end portion 53 of the operating plate portion 51, thereby attaching the cover member 70 to the surface of the operating plate portion 51. As a result, as... Figure 13 As shown, a pair of notches 59B, 59B formed in the operating plate portion 51 are covered by a pair of wall portions 75, 75 of the cover member 70. It should be noted that, as... Figure 17 As shown, a pair of protrusions 35a, 35a of the base member 30 enter a pair of notches 59B, 59B of the operating member 50B, and a pair of wall portions 75, 75 of the cover member 70 are disposed on the outside of the pair of protrusions 35a, 35a.

[0105] According to this embodiment, the operating member 50B also includes a cover member 70 disposed on the surface of the operating plate portion 51. Therefore, by changing the cover member 70, the design of the operating member 50B can be appropriately modified. Furthermore, the cover member 70 is provided with wall portions 75, 75 that cover a pair of notches 59B, 59B formed in the operating plate portion 51. Therefore, as... Figure 18 As shown, when the operating member 50B rotates relative to the base member 30, the pair of notches 59B, 59B can be hidden in a way that they are not visible, thereby improving the appearance.

[0106] (Third embodiment of the locking device for the opening and closing body)

[0107] exist Figures 19-21 The third embodiment of the locking device for the opening and closing body of the present invention is shown. It should be noted that parts that are substantially the same as those in the above embodiments are labeled with the same reference numerals and their descriptions are omitted.

[0108] In the locking device 10C (hereinafter referred to as "locking device 10C") of the opening and closing body in this embodiment, the shaft portion 61C and the base member 30 are separate. Furthermore, the operating member 50C, similar to that in the second embodiment described above, has a cover member 70 disposed on the surface of the operating plate portion 51. Moreover, a pair of plate-shaped pieces 57c, 57c extend from the circumferentially opposite sides of the transmission wall portion 57 of the operating member 50C. It should be noted that this pair of plate-shaped pieces 57c, 57c also constitutes the transmission wall portion 57. Furthermore, circular shaft insertion holes 57d, 57d are formed in the pair of plate-shaped pieces 57c, 57c.

[0109] Moreover, such as Figure 20 As shown, with the pair of plate-shaped pieces 57c, 57c of the operating member 50C disposed inside the pair of protrusions 35a, 35a of the base member 30, the shaft portion 61C is inserted into the shaft support portion 37 disposed in each protrusion 35a and the shaft insertion hole 57d formed in each plate-shaped piece 57c. Thus, the operating member 50C is rotatably supported on the base member 30 via the shaft portion 61C, the shaft support portion 37, and the shaft insertion hole 57d.

[0110] In this embodiment, when the operating part 72 is rotated to its maximum relative to the base member 30, the operating load F1′ is input from the stop receiving part 41 to the stop part 63, and the operating load F1′ is transmitted from the stop part 63 to the transmission wall part 57. The operating load F1′ is transmitted in the semicircular portion 57a ​​of the transmission wall part 57 (see reference). Figure 21 Arrow F2′) is assigned to a pair of plate-like plates 57c, 57c, as... Figure 21 As indicated by arrow F3, a pair of plate-like plates 57c, 57c are to flex and deform in a manner that expands in a direction away from each other. At this time, since a pair of limiting walls 35, 35 are arranged opposite each other on the outer side of the pair of plate-like plates 57c, 57c, the flexural deformation of the pair of plate-like plates 57c, 57c in the radial direction outward of the transmission wall 57 can be limited, thereby improving the breaking strength of the operating member 50C.

[0111] (Fourth embodiment of the locking device for the opening and closing body)

[0112] exist Figures 22-25 The fourth embodiment of the locking device for the opening and closing body of the present invention is shown. It should be noted that parts that are substantially the same as those in the above embodiments are labeled with the same reference numerals and their descriptions are omitted.

[0113] Figure 25 The locking device 10D (hereinafter referred to as "locking device 10D") of the opening and closing body shown in the fourth embodiment has a similar structure to that of the second embodiment, but differs in that a slit 62a is formed at a position adjacent to the shaft portion 61D.

[0114] Specifically, such as Figure 22 As shown, a pair of shaft portions 61D are integrally formed as arc-shaped protrusions in the transmission wall portion 57, and slits 62a are formed at positions adjacent to each shaft portion 61D. Furthermore, as... Figure 24 As shown, shaft support portions 37, 37 are integrally formed on a pair of deformation-limiting walls 35, 35 of the base member 30. It should be noted that the slit 62a includes an arcuate portion extending along the periphery of the top edge side of the transmission wall portion 57 in the erection direction of the shaft portion 61D, and portions extending parallel to each other from the arcuate portion toward the base end side in the erection direction of the transmission wall portion 57. The adjacent portion 62 of the shaft portion 61D (hereinafter, also referred to simply as "shaft portion adjacent portion 62") can flex and deform towards the inside and outside of the operating member 50D via the slit 62a.

[0115] Furthermore, an inner deflection limiting portion 77 is disposed inside the pair of adjacent shaft portions 62, 62 to limit deflection deformation toward the inside of the operating member 50D (here, deflection deformation toward the inside of the transmission wall portion 57). Here, as... Figure 23 As shown, an inner flexural frame-shaped inner flexural restraint portion 77, which is inserted into the transfer wall portion 57, is erected from the back side of the cover member 70D. By positioning this inner flexural restraint portion 77 inside the pair of shaft adjacent portions 62, 62, the flexural deformation of the pair of shaft adjacent portions 62, 62 towards the transfer wall portion 57 is restricted. It should be noted that the flexural deformation restriction of the pair of shaft adjacent portions 62, 62 towards the transfer wall portion 57 could also be provided as a lock cylinder 67, instead of the inner flexural restraint portion 77 described above.

[0116] Furthermore, a pair of wall portions 75, 75 of the cover member 70D are disposed outside the pair of shaft portion adjacent portions 62, 62, restricting the flexural deformation of the pair of shaft portion adjacent portions 62, 62 towards the outside of the transmission wall portion 57 (see reference). Figure 25 ).

[0117] It should be noted that, in addition to the above-mentioned scheme, the following schemes (1) to (5) can also be used as the structure with the slit.

[0118] That is, based on the premise that the shaft part is protruding and the shaft support part is grooved (the above structure is also the same), the following structures can be set: (1) a slit is formed at the position adjacent to the shaft part and a slit is also formed at the position adjacent to the shaft support part, so that both the slit adjacent part of the shaft part and the slit adjacent part of the shaft support part can be flexibly deformed; (2) no slit is formed at the position adjacent to the shaft part, but a slit is formed at the position adjacent to the shaft support part, so that only the slit adjacent part of the shaft support part can be flexibly deformed, etc.

[0119] Furthermore, based on the premise that the shaft portion is grooved and the shaft support portion is protruding, the following structures can also be constructed: (3) A slit is formed at the position adjacent to the shaft portion, but no slit is formed at the position adjacent to the shaft support portion, so that only the slit adjacent portion of the shaft portion can be flexed and deformed; (4) A slit is formed at the position adjacent to the shaft portion, and a slit is also formed at the position adjacent to the shaft support portion, so that both the slit adjacent portion of the shaft portion and the slit adjacent portion of the shaft support portion can be flexed and deformed; (5) No slit is formed at the position adjacent to the shaft portion, but a slit is formed at the position adjacent to the shaft support portion, so that only the slit adjacent portion of the shaft support portion can be flexed and deformed, etc.

[0120] In addition, in this embodiment, the shaft portion 61D is integrally formed with the operating load transmission wall portion 57, and the shaft support portion 37 is integrally formed with a pair of deformation limiting walls 35, 35. However, it is also possible that the shaft support portion is integrally formed with the operating load transmission wall portion, and the shaft portion is integrally formed with a pair of deformation limiting walls.

[0121] It should be noted that, according to the above-described structures (1) to (5), if the slit adjacent portion of the shaft portion or the slit adjacent portion of the shaft support portion can bend or deform towards the inside or outside of the operating member or the base member, the inner bending limiting portion and the lock cylinder are disposed inside the slit adjacent portion of the shaft portion or the slit adjacent portion of the shaft support portion, and the outer bending limiting portion is disposed outside the slit adjacent portion of the shaft portion or the slit adjacent portion of the shaft support portion. That is, the structure becomes as follows: (a) a structure having only the inner bending limiting portion or the lock cylinder ( Figures 22-25 The fourth embodiment shown is the structure; (b) a structure having only an outer flexure limiting portion; (c) a structure having both an inner flexure limiting portion and a lock cylinder and an outer flexure limiting portion.

[0122] Moreover, in this embodiment, such as Figure 24 As indicated by arrow F4, firstly, the operating member 50D is assembled to the base member 30. In this case, a pair of transmission walls 57, 57 are inserted into the inside of a pair of limiting walls 35, 35. At this time, the top ends of a pair of shafts 61D, 61D are pressed by the inner surfaces of the pair of limiting walls 35, 35, and the pair of shaft abutment portions 62, 62 are inserted while flexing inward. Moreover, when the pair of shafts 61D, 61D reach a pair of shaft supports 37, 37, the pair of shaft abutment portions 62, 62 elastically recover, and the pair of shafts 61D, 61D are inserted into the pair of shaft supports 37, 37, and the operating member 50D is assembled to the base member 30.

[0123] Then, as Figure 24As indicated by arrow F5, the cover member 70D is attached to the operating member 50D. That is, the top end portion 52B of the operating plate portion 51 is inserted into and locked into the locking frame portion 72a of the cover plate portion 71, and the locking protrusions 73a, 73a of the cover plate portion 71 are locked into both sides of the base end portion 53 of the operating plate portion 51 in the width direction, thereby attaching the cover member 70D to the surface of the operating plate portion 51. At this time, as... Figure 25 As shown, the inner flexure limiting part 77 provided on the cover member 70D is inserted into the inner side of a pair of shaft adjacent portions 62, 62, thereby limiting the flexure deformation of the pair of shaft adjacent portions 62, 62 toward the inner side of the operating member 50D, that is, toward the inner side of the transmission wall portion 57.

[0124] As described above, in this embodiment, a slit is formed in the operating load transmission wall and / or a pair of deformation limiting walls at a position adjacent to the shaft and / or shaft support. Through this slit, the adjacent portion of the shaft and / or the adjacent portion of the shaft support can flex and deform towards the inside and outside of the operating member or the base member (here, a slit 62a is formed at a position adjacent to the shaft 61D, and the adjacent portion 62 of the shaft can flex and deform towards the inside and outside of the transmission wall 57 of the operating member 50D through this slit 62a). Therefore, the assembly operability of the operating member 50D relative to the base member 30 can be improved.

[0125] Furthermore, it has an inner deflection limiting part or lock cylinder disposed inside the adjacent portion of the shaft or shaft support to limit the inward deflection of the operating load transmission wall, and / or an outer deflection limiting part disposed outside the adjacent portion of the shaft support or shaft to limit the outward deflection of a pair of deformation limiting walls. Here, the inner deflection limiting part 77 is disposed inside the pair of adjacent portions 62, 62 of the shaft. As a result, after the operating member 50D is assembled to the base member 30, it is not easy to remove the operating member 50D from the base member 30. That is, the deflection deformation of the adjacent portion of the slit of the shaft or the adjacent portion of the slit of the shaft support formed by the inner deflection limiting part or lock cylinder and the outer deflection limiting part can be limited, so it is not easy to remove the operating member from the base member.

[0126] It should be noted that the present invention is not limited to the above-described embodiments. Various modified embodiments can be implemented within the scope of the present invention, and such embodiments are also included within the scope of the present invention.
