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

[0009] Problems to be solved by the invention

[0010] In the case of the locking device of the above-mentioned Patent Document 1, when the operating member is rotated to the maximum with respect to the base member, the operating force (operating load) of the operating member is transmitted from the anti-rotation portion via the cylindrical portion having the hole for the lock core and the base to the pair of side wall portions, and acts on the pair of shaft portions. 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 portion, the cylindrical portion, the base, and the pair of side wall portions, but this will lead to an increase in mass, and therefore, there is a disadvantage that it is difficult to improve the breaking strength of the operating member.

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

[0012] Solutions for solving problems

[0013] In order to achieve the above-mentioned object, the present invention is a locking device for an opening and closing body installed at an opening part of a fixed body in an openable and closable manner, the locking device of the opening and closing body is characterized in that it comprises: a locking portion provided on one of the fixed body or the opening and closing body; a locking member configured on the fixed body or the other of the opening and closing body and engaged with / disengaged from the locking portion; a base member fixed to the fixed body or the other of the opening and closing body; and an operating member rotatably supported on the base member via a rotating portion for operating the locking member, the rotating portion being composed of a shaft portion and a shaft supporting portion, wherein the shaft portion is provided on one of the operating member or the base member, the shaft supporting portion is provided on the operating member or the other of the base member to support the shaft portion so as to be rotatable, and the operating member comprises: an operating plate portion extending in a plate shape; an operating portion provided on the operating plate The cam is an axially-coupled device for translating a rotation of the cam into and out of the operating member, wherein the cam is configured to extend along the length of the operating member and wherein the cam is configured to extend along the length of the operating member.

[0014] Effects of the Invention

[0015] According to the present invention, when the operating portion is operated so that the operating member is rotated to the maximum with respect to the base member, the stopper abuts against the stop receiving portion to limit the rotation of the operating member. At this time, since the stopper is connected to the operating load transfer wall portion provided with the shaft portion or the shaft support portion, the operating load received by the stopper from the stop receiving portion is transferred to the shaft portion via the operating load transfer wall portion, and the portion of the operating load transfer wall portion provided with the shaft portion or the shaft support portion, the shaft portion provided to protrude from both sides of the operating load transfer wall portion, or the shaft support portion provided on the operating load transfer wall portion is intended to deform in a manner of expanding toward the outside of the operating member, but the deformation is limited by a pair of deformation limiting wall portions. As a result, the breaking strength (difficulty of breaking the operating member) of the operating member can be increased without increasing the rigidity of the operating member.

Figure 1 As shown, the opening and closing body 2 of this embodiment includes: an outer member 3, which is arranged on the inner side of the vehicle compartment; and an inner member 4, which is arranged on the back side of the outer member 3. A concave accommodating recess 5 with a transversely long rectangular shape is formed on one side of the width direction of the outer member 3 and above it. The base member 30 and the operating member 50 are accommodated in the accommodating recess 5 (refer to Figure 6 ). Moreover, a mounting hole 6 in the shape of a long hole is formed at the bottom 5 a of the accommodating recess 5 .

[0048] The base member 30 is installed from the front side of the above-mentioned mounting hole 6. It should be noted that the "front side" or "surface side" mentioned here refers to a side or a surface located in the direction of opening of the opening and closing body from the opening portion of the fixed body of the vehicle, etc. It should be noted that, in the case where the fixed body is provided in the vehicle, the side of the vehicle interior space is set as the "front side" or "surface side". In addition, the "back side" or "back side" refers to the side opposite to the "front side" or "surface side", that is, a side or a surface located in the direction of closing the opening and closing body. It should be noted that not only for the mounting hole, but also for other components (base member 30, operating member 50, etc.) described below, the "front side", "surface side", "back side" and "back side" have the same meaning.

[0049] like Figure 1 As shown, the inner member 4 is in the shape of a box with an upper opening. In addition, a locking configuration recess 4a having a horizontally long concave shape is provided on the surface side (front side) of the inner member 4 that is arranged opposite to the outer member 3 and the upper part thereof, and the locking configuration recess 4a configures the pair of locking members 20, 20 to be slidable. Locking through holes 4b, 4b are respectively formed on both sides of the long dimension direction of the locking configuration recess 4a. In addition, a rotating member support part 7 for rotatably supporting the rotating member 25 is protruding from the surface side of the bottom surface of the locking configuration recess 4a.

[0050] In addition, if Figure 1 , Fig.10As shown, the pair of locking members 20, 20 in this embodiment are of the same shape, the base end 21 side of the locking member 20 is bent into a crank shape, and extends straight toward the top end side, and the top end 22 of the locking member 20 is engaged / disengaged with the locking portion 1b (refer to Fig.10 , Fig.11 A frame-like portion 23 having a rectangular frame shape is provided on the side of the top end portion 22 of each locking member 20 .

[0051] The rotating member 25 has a substantially rhombus shape with a long axis (see Fig.10 ), the middle part of which in the longitudinal direction is rotatably supported by the rotating member support part 7, and both ends in the longitudinal direction are connected to the base ends 21, 21 of a pair of locking members 20, 20. The rotating member 25 rotates in a predetermined direction, whereby the pair of locking members 20, 20 slide synchronously via the rotating member 25. In addition, a torsion spring 27 is attached to the rotating member 25, such as Fig.10 As shown in the direction of arrow A, the rotating member 25 is rotated and forced, thereby the top ends 22, 22 of the pair of locking members 20, 20 are moved in the direction of engagement with the pair of locking parts 1b, 1b ( Fig.10 It should be noted that the top ends 22, 22 of the pair of locking members 20, 20 are inserted through the locking insertion holes 4b, 4b provided in the locking configuration recess 4a.

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

[0053] The base member 30 of the present embodiment is composed of the following structure: a bottom wall 31, which is in the shape of a long plate long in one direction; a pair of side wall portions 32, 32, which are erected from the two side edges 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 arranged on one end side of the long dimension direction of the bottom wall 31, and connects the pair of side wall portions 32, 32 to each other; and a connecting wall 34, which is arranged on the other end side of the long dimension direction of the bottom wall 31, and connects the pair of side wall portions 32, 32 to each other. The base member 30 is in the shape of a roughly long box with an opening on the top (upper) 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 set as the "extension direction X1", and the direction orthogonal to the extension direction X1 is set as the "width direction Y1" (the same meaning also applies to the base member 30 itself and the parts other than the bottom wall 31 constituting the base member 30).

[0055] The bottom wall 31 is formed with a slide groove 31 a, and the slide groove 31 a receives the operating rod 65 (see FIG. 1 ) of the operating member 50. Figure 3) is slidably received. In addition, protrusions 35a, 35a in a substantially trapezoidal mountain shape are protruded from the upper side of a pair of side wall portions 32, 32 (on the opposite side of the bottom wall 31) and close to the connecting wall 34.

[0056] Moreover, if Figure 1 As shown, the portion of the pair of side wall portions 32, 32 including the protruding piece 35a and close to the other end portion of the extension direction X2 forms a pair of limiting wall portions 35, 35. The pair of limiting wall portions 35, 35 are arranged to face the outer side of the portion of the transmission wall portion 57 provided with the shaft portion 61 (here, the portion of the pair of flat surfaces 57b, 57b of the transmission wall portion 57 described later provided with the shaft portion 61, 61), and become a portion that limits the deformation of the transmission wall portion 57. It should be noted that the inner surfaces (opposing surfaces) of the pair of limiting wall portions 35, 35 are formed to be parallel to each other.

[0057] In addition, a circular hole-shaped shaft support portion 37 is formed through the protruding pieces 35a, 35a constituting the pair of limiting wall portions 35, 35. Figure 7 , Figure 8 As shown, each shaft portion 61 of the operation member 50 is inserted from the inner side of each shaft support portion 37 , so that the operation member 50 is rotatably supported by the base member 30 .

[0058] In addition, on the outer surface of each side wall portion 32 and on the side of the bottom wall 31, there are provided: a flexible elastic engaging piece 38 formed via a "U"-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 side periphery of the mounting hole 6, and the rib 39 engages with the front side periphery of the mounting hole 6 (refer to Figure 7 ).

[0059] In addition, a pair of hooks 40, 40 are provided protruding from the bottom wall 31 side of the connecting wall 33 and on both sides in the width direction Y1, and are engaged with the back side periphery of the mounting hole 6. In addition, a notch 41a is cut from the bottom wall 31 toward the top opening in the middle part of the connecting wall 33 in the width direction Y1, and a stopper receiving portion 41 is provided on the side of the connecting wall 33 opposite to the bottom wall 31 side through the notch 41a. Fig. 9 As shown, when the operating portion 52 of the operating member 50 is rotated maximally relative to the base member 30 in a direction away from the base member 30 and the bottom 5a of the accommodating recess 5, the stop portion 63 abuts against the stop receiving portion 41, and further rotation of the operating member 50 is restricted.

[0060] In addition, a pair of elastic engagement claws 42, 42 are provided from the bottom wall 31 side of the connecting wall 34 and on both sides in the width direction Y1 thereof, which engage with the back side periphery of the mounting hole 6. Moreover, a rubber damper 43 is attached to the corner portion on one end side of the extension direction X1 of the base member 30, thereby achieving a reduction in the impact sound when the operating portion 52 of the operating member 50 is rotated in a direction close to the base member 30 or the bottom 5a of the accommodating recess 5. In addition, a coil spring 44 is arranged at the corner portion on the other end side of the extension direction X1 of the base member 30.

[0061] Next, refer to Figure 2 to Figure 8 The operation member 50 will be described in detail.

[0062] The operating member 50 of this embodiment is in the shape of a long strip in one direction as a whole, and has an operating plate portion 51 which is substantially in the shape of a long plate and extends in a plate shape with a predetermined length. It should be noted that in the following description, the extension direction of the operating plate portion 51 is set as the "extension direction X2", and the direction orthogonal to the extension direction X2 is set as the "width direction Y2" (the same meaning is also applied to the operating member 50 itself and the parts other than the operating plate portion 51 constituting the operating member 50, and the cover member 70 described further below).

[0063] An operating portion 52 is provided at one end (top end) of the operating plate portion 51 in the extension direction X2, and the operating portion 52 becomes a portion for the operator to hold and operate when the operating member 50 is rotated. In addition, the other end of the operating plate portion 51 in the extension direction X2 becomes a base end 53 of a pair of shaft support portions 37, 37 that are rotatably supported on the base member 30. Moreover, a lock core insertion hole 51a in the shape of a circular hole for inserting the lock core 67 is formed on the other end side of the extension direction X2 of the operating plate portion 51. In addition, a damper abutment portion 51b in the shape of a substantially cylindrical protrusion for abutting against the damper 43 is protrudingly provided on the back side (the side opposite to the base member 30) of the operating plate portion 51 and close to one end in the extension direction X2.

[0064] Furthermore, a pair of side walls 55, 55 extending in the extension direction X2 of the operation plate portion 51 are erected from both side edges in the width direction Y2 of the operation plate portion 51 toward the back side (toward the base member 30 side). In addition, recessed portions 59, 59 for receiving the pair of protruding pieces 35a, 35a of the base member 30 are formed on the other end sides of the pair of side walls 55, 55 in the extension direction X2.

[0065] Furthermore, a substantially cylindrical transmission wall portion 57 is provided from the back side of the operation plate portion 51 and the back side periphery of the lock core insertion hole 51a, into which the lock core 67 can be inserted. The transmission wall portion 57 will be described in detail later, but Figure 8As shown, it plays a role in transmitting the operation load inputted via the stopper 63 to the pair of shaft portions 61, 61 (refer to Figure 8 It should be noted that the above-mentioned operation load is mainly applied to the semicircular portion 57a ​​(see FIG. 5 ) located closer to the operation portion 52 than the pair of shaft portions 61, 61 in the transmission wall portion 57. Figure 8 )transfer.

[0066] Furthermore, flat surfaces 57b, 57b are formed parallel to each other at positions matching the pair of recessed portions 59, 59 on the outer periphery of the two side portions (the two side portions in the width direction Y2) of the transmission wall portion 57 that are opposite to each other in the circumferential direction. A pair of shaft portions 61, 61 are coaxially protruded from the pair of flat surfaces 57b, 57b at positions close to the operation plate portion 51 (positions on the base end side of the transmission wall portion 57 in the direction of erection).

[0067] Furthermore, if Figure 4 As shown, when the operating member 50 is viewed from the back side (when viewed from the rear side), the pair of shaft portions 61, 61 extend from the other end portion (close to the base end portion 53) in the extension direction X2 of the operating member 50 relative to the axis C of the transmission wall portion 57 along the width direction Y2 of the operating member 50, and are connected to the transmission wall portion 57. Figure 3 As shown, a tapered surface 61a is formed at the top end of each shaft portion 61, and the tapered surface 61a is cut obliquely from the base end side of the transmission wall portion 57 in the upright setting direction toward the top end side in the upright setting direction, making it easy to insert the shaft portion 61 from the inner side of the shaft support portion 37.

[0068] When the operating member 50 is assembled to the base member 30, the pair of shaft portions 61, 61 of the operating member 50 are inserted between the pair of protruding pieces 35a, 35a of the base member 30, and the operating member 50 is pressed into the base member 30. Then, the pair of shaft portions 61, 61 are inserted from the inside into the pair of shaft support portions 37, 37 of the base member 30 (see Figure 7 , Figure 8 ), thereby the operation member 50 is rotatably supported on the base member 30. As a result, the pair of restriction wall portions 35, 35 of the base member 30 are arranged opposite to each other on the outer sides of the pair of flat surfaces 57b, 57b (see Figure 7 , Figure 8). In particular, the protrusions 35a, 35a constituting the pair of limiting wall portions 35, 35 are arranged outside the portion of the pair of flat surfaces 57b, 57b provided with 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 protrusions 35a, 35a are both flat surfaces, and therefore, the flat surface 57b and the inner surface of the limiting wall portion 35 are arranged opposite to each other at a close position, and the gap between the flat surface 57b and the inner surface of the limiting wall portion 35 becomes smaller. Moreover, as Figure 6 , Fig. 9 As shown, the operating member 50 rotates relative to the base member 30 with the pair of shaft portions 61 , 61 as a rotation fulcrum so 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 5 a of the accommodating recess 5 .

[0069] In addition, if Figure 6 As shown, the coil spring 44 is interposed in a compressed state between the other end of the operating member 50 in the extending direction X2 and the other end of the base member 30 in the extending direction X1. Fig. 9 As shown, after the operating member 50 is rotated relative to the base member 30 in a manner that the operating portion 52 of the operating plate portion 51 of the operating member 50 is away from the base member 30 and the bottom 5a of the accommodating recess 5, when the operator's hand is removed from the operating portion 52, a force is applied to rotate the operating portion 52 in a direction close to the base member 30 and the bottom 5a of the accommodating recess 5.

[0070] Furthermore, if Figure 3 As shown in FIG. 1 , a stopper 63 is provided protruding from the outer surface of the transmission wall 57 on the side of the operation portion 52 and the top end of the transmission wall 57 in the direction of the vertical setting and closer to the operation portion 52 than the pair of shaft portions 61, 61. The stopper 63 is arranged orthogonally to the pair of shaft portions 61, 61 and is connected to the transmission wall 57. That is, the transmission wall 57, the pair of shaft portions 61, 61 and the stopper 63 are formed continuously as a whole. Fig. 9 As shown, when the operating member 50 is rotated maximally relative to the base member 30 in a manner such that the operating portion 52 of the operating member 50 is in a direction away from the base member 30 and the bottom 5a of the accommodating 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, if Figure 3As shown, an operating rod 65 is erected from the back side of one end side of the extension direction X2 of the operating plate portion 51. A portion of the operating rod 65 is connected to a portion of the transmission wall portion 57 that is opposite to the portion where the stop portion 63 is provided in the circumferential direction, and the operating rod 65 is erected in a manner higher than the top end portion of the transmission wall portion 57 in the erection direction. In addition, the operating rod 65 passes through the back side of the sliding groove 31a of the base member 30 and enters the frame-like portion 23 of one locking member 20. Moreover, when the operating portion 52 of the operating member 50 is rotated in a direction away from the base member 30 and the bottom 5a of the accommodating recess 5, the above-mentioned operating rod 65 presses the frame-like portion 23 of one locking member 20, so that the top ends 22, 22 of the pair of locking members 20, 20 are slid in a direction that is not engaged with the pair of locking portions 1b, 1b of the fixed body 1 via the rotating member 25 (refer to Fig.11 ).

[0072] Moreover, in the locking device 10, the configuration is as follows: when the operating part 52 is operated to rotate 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 portion 52 of the operating member 50 is held, and as shown by arrow F1, the operating portion 52 is rotated as far as possible relative to the base member 30 in a direction away from the base member 30 or the bottom 5a of the accommodating recess 5, as shown in FIG. Fig. 9 As shown, the stopper 63 abuts against the stopper receiving portion 41, and further rotation of the operating member 50 is restricted. Then, the stopper 63 receives the operating load F1′ from the stopper receiving portion 41. That is, the operating load F1′ is input from the stopper receiving portion 41 to the stopper 63, and thus the operating load F1′ is transmitted from the stopper 63 to the transmission wall portion 57.

[0074] Then, the operation load F1′ is applied from the portion of the transmission wall 57 where the stopper 63 is located, that is, the circumferential center of the semicircular portion 57a ​​of the transmission wall 57 which is closer to the operation portion 52 than the pair of shaft portions 61, 61. Fig. 9 As shown by the arrow F2, the semicircular portion 57a ​​is transmitted to the axial base end side, and as shown in FIG. Figure 8 As shown by the arrow F2′, the operating load F1′ is transmitted to both ends of the semicircular portion 57a ​​in the circumferential direction. As a result, the operating load F1′ is applied to the portion of the transmission wall portion 57 provided with the shaft portions 61, 61, that is, the portion of the pair of flat surfaces 57b, 57b constituting the transmission wall portion 57 provided with the pair of shaft portions 61, 61. Figure 8As shown by the arrow F3, the pair of flat surfaces 57b, 57b are intended to bend and deform in a manner of expanding in directions away from each other (it can also be said that the pair of flat surfaces 57b, 57b are intended to bend and deform toward the radial outside of the transfer wall portion 57 in a manner of expanding the interval between the base ends of the pair of shaft portions 61, 61. Further, it can also be said that the pair of shaft portions 61, 61 are bent and deformed toward the radial outside of the transfer wall portion 57).

[0075] At this time, a pair of limiting wall portions 35, 35 are disposed opposite to each other on the outer sides of the pair of flat surfaces 57b, 57b. In particular, a pair of protruding pieces 35a, 35a constituting the pair of limiting wall portions 35, 35 are disposed opposite to each other on the outer sides of the portion of the pair of flat surfaces 57b, 57b where the pair of shaft portions 61, 61 are disposed. Therefore, the bending deformation of the portion of the pair of flat surfaces 57b, 57b where the pair of shaft portions 61, 61 are disposed and the pair of shaft portions 61, 61 to the radial outer side of the transmission wall portion 57 is restricted. It should be noted that in the present embodiment, the lock core 67 is inserted and disposed inside the transmission wall portion 57, so that the bending deformation of the transmission wall portion 57 to the radial inner side is restricted.

[0076] (Variation Example)

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

[0078] In addition, in the present embodiment, as described above, for example, it is applicable to a structure in which a box-shaped glove box is rotatably mounted on an opening portion of the instrument panel (in this case, the instrument panel becomes a "fixed body" and the glove box becomes an "opening and closing body"), but it can also be applicable to a structure in which a lid is mounted on an opening portion of the instrument panel in an openable and closable manner (in this case, the instrument panel becomes a "fixed body" and the lid becomes an "opening and closing body"), and can be widely used for various opening and closing bodies for opening and closing the opening portion of a fixed body.

[0079] Moreover, in this embodiment, the mounting hole 6 is formed in the opening and closing body 2, and the locking member 20 is slidably arranged on the opening and closing body 2, but it is also possible that the mounting hole is formed in the fixed body and the locking member is slidably arranged on the fixed body side.

[0080] In addition, the locking portion 1b in this embodiment is in the shape of a hole, but the locking portion may not be in the shape of a hole, but may be in the shape of a recess, a protrusion, a frame, etc. In addition, the locking portion may be provided on the opening and closing body instead of the opening portion of the fixed body.

[0081] Furthermore, the torsion spring 27 as the biasing means in this embodiment biases the rotating member 25 to rotate, thereby biasing the lock member 20 connected to the rotating member 25 in a direction to engage with the lock portion 1b (see Fig.10 ), but as a biasing unit that biases the locking member in the direction of engagement with the locking portion, for example, a tension spring that pulls one side of the locking member toward the locking portion side may also be used.

[0082] In addition, 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, but it can also be configured such that the rotating member rotates by rotating the operating member, thereby sliding a pair of locking members.

[0083] Furthermore, the opening and closing body 2 in the present embodiment is composed of the outer member 3 and the inner member 4, but the opening and closing body may be composed of a single plate material.

[0084] The shaft support portion 37 formed in the base member 30 is in the shape of a circular hole, but the shaft support portion may be, for example, an arc-shaped groove (this will be described in the embodiment described later) or an arc-shaped protrusion.

[0085] Moreover, the pair of shaft portions 61, 61 in this embodiment are connected to the transmission wall portion 57, but the shaft portion may be set as a separate body from the operation load transmission wall portion (this will be described in the embodiment described later). It should be noted that the shaft portion is a shape suitable for the shape of the shaft support portion. For example, when the shaft support portion is a circular arc groove as described in paragraph 0053, the shaft portion is preferably set as a circular arc protrusion.

[0086] Furthermore, in this embodiment, a lock core 67 is inserted and arranged inside the transfer wall portion 57, and the radially inward flexural deformation of the transfer wall portion 57 is restricted. However, it is also possible to configure a configuration in which the lock core is not inserted into the operating load transfer wall portion, or to insert and arrange other components different from the lock core into the operating load transfer wall portion (this will be described in the embodiment to be described later).

[0087] Moreover, in the present embodiment, the rotating portion that enables the operating member 50 to be rotatably supported on the base member 30 is composed of the shaft portion 61 provided on the operating member 50 and the shaft support portion 37 provided on the base member 30, but the rotating portion may also be a structure composed of the shaft portion provided on the base member and the shaft support portion provided on the operating member.

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

[0089] Furthermore, the transmission wall portion 57 in the present embodiment is substantially cylindrical, but the operation load transmission wall portion may be, for example, semi-cylindrical, triangular cylindrical, V-frame, U-frame, or the like.

[0090] exist Fig.12 , a modified example of an operation load transmission wall portion 68 (hereinafter, also simply referred to as "transmission wall portion 68") is described. The transmission wall portion 68 is a frame-shaped structure consisting of a pair of inclined ribs 68a, 68a extending in a manner of expanding outwardly from one end side of the extension direction X2 of the operating member 50A toward the other end side; curved ribs 68b, 68b formed in a curved manner at the top end of the pair of inclined ribs 68a, 68a in the extension direction, extending along the extension 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 end of the pair of inclined ribs 68a, 68a in the extension direction along the extension direction X2 of the operating member 50A, and connecting to the center of the first connecting rib 68c in the extension direction. Furthermore, stoppers 63 are provided at base ends of the pair of inclined ribs 68a, 68a and the second connecting rib 68d in the extending direction, and shaft portions 61, 61 are provided to protrude from outer surfaces of the curved ribs 68b, 68b.

[0091] In the case of such a transmission wall portion 68, when the operation load input from the stopper receiving portion 41 to the stopper portion 63 is transmitted from the stopper portion 63 to the transmission wall portion 57, the operation load is transmitted to the pair of inclined ribs 68a, 68a (see Fig.12 The arrow F2′ acts on the pair of curved ribs 68b, 68b, causing the pair of curved ribs 68b, 68b to bend and deform in a manner that expands in directions away from each other (refer to Fig.12 However, in this case, too, a pair of deformation limiting wall portions (not shown) are arranged outside the pair of bending ribs 68b, 68b to limit the radially outward bending deformation of the pair of bending ribs 68b, 68b.

[0092] (Effect)

[0093] Next, the effects of the locking device 10 having the above-described structure will be described.

[0094] In the locking device 10, the opening and closing body 2 is closed from the opening portion 1a of the fixed body 1, and the top ends 22, 22 of the pair of locking members 20, 20 are engaged with the locking portions 1b, 1b of the fixed body 1 (see Fig.10 ), thereby locking the opening and closing body 2 in the closed state.

[0095] From this state, if Fig. 9 As shown in FIG. 1 , when the operating portion 52 of the operating member 50 is rotated in a direction away from the base member 30 and the bottom 5a of the accommodating recess 5, as shown in FIG. Fig.11 As shown, the top end 22 of the locking member 20 on one side is pulled from the locking portion 1b to the direction of non-engagement by resisting the rotational force applied by the rotating member 25, and the top end 22 of the locking member 20 on the other side is pulled from the locking portion 1b to the direction of non-engagement via the rotating member 25 in conjunction with the rotational force applied by the rotating member 25, thereby releasing the locking state of the opening and closing body 2 and opening the opening and closing body 2 from the opening portion 1a of the fixed body 1.

[0096] Furthermore, in the locking device 10, as described in the above paragraph 0043, when the operating portion 52 of the operating member 50 is grasped and the operating portion 52 is rotated to the maximum with respect to the base member 30, the stopper 63 abuts against the stopper receiving portion 41, and the operating load F1′ is input from the stopper receiving portion 41 to the stopper 63, and the operating load F1′ is transmitted from the stopper 63 to the transmission wall portion 57 (see Fig. 9 ). Then, as described in the above paragraph 0044, the operation load F1' is transmitted to the semicircular portion 57a ​​of the transmission wall portion 57 (refer to Figure 8 Arrow F2′) is given to a pair of flat surfaces 57b, 57b, such as Figure 8 As shown by the arrow F3, the portion of the pair of flat surfaces 57b, 57b provided with the pair of shaft portions 61, 61 and the pair of shaft portions 61, 61 are bent and deformed in a manner of expanding in a direction away from each other. At this time, a pair of limiting wall portions 35, 35 (here, a pair of protruding pieces 35a, 35a are arranged opposite to each other on the outside of the pair of flat surfaces 57b, 57b) can be restricted from bending and deforming the portion of the pair of flat surfaces 57b, 57b provided with the pair of shaft portions 61, 61 and the pair of shaft portions 61, 61 toward the radial outside of the transmission wall portion 57. As a result, the breaking strength of the operating member 50 (the difficulty of breaking the operating member 50) can be improved without increasing the rigidity of the operating member 50.

[0097] Furthermore, in the present embodiment, the transmission wall portion 57 has a cylindrical shape into which the key cylinder 67 can be inserted.

[0098] According to this scheme, before the lock cylinder 67 is inserted into the transmission wall portion 57, the transmission wall portion 57 can be easily deformed toward the radial inner side. Therefore, when the transmission wall portion 57 is arranged between the pair of limiting wall portions 35, 35 of the base member 30 in order to assemble the operating member 50 to 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, which can improve the assembly workability of the operating member 50 with respect to the base member 30. In addition, when the lock cylinder 67 is inserted into the transmission wall portion 57 in the state where the shaft portion 61 is supported by the shaft support portion 37, the deformation of the transmission wall portion 57 toward the radial inner side can be restricted. Therefore, the rigidity of the transmission wall portion 57 itself, the shaft portion 61 provided on the transmission wall portion 57, and the stopper portion 63 can be improved.

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

[0100] exist Figures 13 to 18 A second embodiment of the locking device for an opening and closing body of the present invention is shown in FIG. It should be noted that substantially the same parts as those in the above-mentioned embodiment are denoted by the same reference numerals and their description is omitted.

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

[0102] like Fig.14 As shown, in the operating member 50B, a pair of notches 59B, 59B extending along the extension direction X2 of the operating plate portion 51 are cut out on the base end portion 53 side of the operating plate portion 51 and on both side edges in the width direction Y2. The pair of notches 59B, 59B are configured to allow the pair of protruding pieces 35a, 35a of the base member 30 to enter (see Fig.17 ). In addition, the pair of shaft portions 61, 61 protruding from the 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, Fig.15As shown, the cover member 70 has a cover plate portion 71, which is in the shape of a generally long plate extending in a plate-like manner with a predetermined length in a manner suitable for the operating 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 side edges in the width direction of the cover plate portion 71 toward the back side (toward the operating member 50B side). In addition, a pair of locking protrusions 73a, 73a for locking with both sides in the width direction of the base end portion 53 of the operating plate portion 51 are formed on the side of the base end portion 73 in the extension direction X2 of the cover plate portion 71. It should be noted that the operating portion 72 is formed on the side of the top end portion in the extension direction X2 of the cover plate portion 71. In addition, a protrusion 73a, 73a for the top end portion 52B of the operating plate portion 51 to enter and lock is provided on the side of the base end portion 73 of the cover plate portion 71 that is closer to the operating portion 72 (refer to Fig.16 ) locking frame portion 72a.

[0104] Furthermore, the top end portion 52B of the operation plate portion 51 is inserted into and locked in the locking frame portion 72a of the cover plate portion 71, and the locking projections 73a, 73a of the cover plate portion 71 are locked with both sides in the width direction of the base end portion 53 of the operation plate portion 51, thereby attaching the cover member 70 to the front side of the operation plate portion 51. As a result, as Fig.13 As shown in FIG. 1 , a pair of notches 59B, 59B formed in the operation plate portion 51 are covered by a pair of wall portions 75, 75 of the cover member 70. Fig.17 As shown, the pair of protruding pieces 35a, 35a of the base member 30 enter the pair of notches 59B, 59B of the operation member 50B, and the pair of wall portions 75, 75 of the cover member 70 are arranged outside the pair of protruding pieces 35a, 35a.

[0105] According to the present embodiment, the operating member 50B further includes a cover member 70 disposed on the surface side of the operating plate portion 51. Therefore, by changing the cover member 70, the design of the operating member 50B can be appropriately changed. In addition, the cover member 70 is provided with wall portions 75, 75 covering a pair of notches 59B, 59B formed in the operating plate portion 51. Fig.18 As shown, when the operation member 50B is rotated relative to the base member 30, the pair of notches 59B and 59B can be hidden so as not to be seen, and the appearance can be improved.

[0106] (Third Embodiment of the Locking Device for Opening and Closing Body)

[0107] In Figure 19 to Figure 21 A third embodiment of the locking device for an opening and closing body of the present invention is shown in FIG. It should be noted that substantially the same parts as those in the above-mentioned embodiment are denoted by the same reference numerals and their description is omitted.

[0108] In the locking device 10C of the opening and closing body of the present embodiment (hereinafter, simply referred to as "locking device 10C"), the shaft portion 61C and the base member 30 are separate bodies. In addition, the operating member 50C has a cover member 70 arranged on the surface side of the operating plate portion 51, similarly to the above-mentioned second embodiment. Moreover, a pair of plate-like pieces 57c, 57c extend from the circumferentially opposite side portions of the transmission wall portion 57 of the operating member 50C. It should be noted that the pair of plate-like pieces 57c, 57c also constitute the transmission wall portion 57. In addition, axle insertion holes 57d, 57d in the shape of circular holes are formed in the pair of plate-like pieces 57c, 57c.

[0109] Moreover, if Fig. 20 As shown, when a pair of plate-like pieces 57c, 57c of the operating member 50C are arranged on the inner side of a pair of protrusions 35a, 35a of the base member 30, the shaft portion 61C is respectively inserted into the shaft support portion 37 arranged on each protrusion 35a and the shaft insertion hole 57d formed on each plate-like piece 57c, thereby, 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 portion 72 is rotated to the maximum with respect to the base member 30, the operating load F1′ is input from the stopper receiving portion 41 to the stopper 63, and the operating load F1′ is transmitted from the stopper 63 to the transmission wall portion 57, and the operating load F1′ is transmitted in the semicircular portion 57a ​​of the transmission wall portion 57 (see Fig.21 The arrow F2′) is given to a pair of plate-like pieces 57c, 57c, such as Fig.21 As shown by the arrow F3, the pair of plate-like pieces 57c, 57c is bent and deformed in a manner of expanding in the direction away from each other. At this time, since a pair of limiting wall portions 35, 35 are arranged opposite to each other on the outside of the pair of plate-like pieces 57c, 57c, the bending deformation of the pair of plate-like pieces 57c, 57c toward the radial outside of the transmission wall portion 57 can be limited, and the destructive strength of the operating member 50C can be improved.

[0111] (Fourth Embodiment of the Locking Device for Opening and Closing Body)

[0112] exist Figure 22 to Figure 25 A fourth embodiment of the locking device for an opening and closing body of the present invention is shown in FIG. It should be noted that substantially the same parts as those in the above-mentioned embodiment are denoted by the same reference numerals and their description is omitted.

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

[0114] Specifically, if Fig. 22 As shown in FIG. 1 , a pair of shaft portions 61D are formed as arc-shaped protrusions integrally formed on the transmission wall portion 57, and slits 62a are formed at positions adjacent to the shaft portions 61D. Fig.24 As shown, the shaft support parts 37, 37 are integrally formed with a pair of deformation restricting wall parts 35, 35 of the base member 30. It should be noted that the slit 62a includes an arc-shaped portion extending along the peripheral edge of the transmission wall part 57 of the shaft part 61D on the side of the top end part in the erection direction and a portion extending parallel to each other from the arc-shaped portion toward the side of the base end part in the erection direction of the transmission wall part 57. The adjacent portion 62 of the shaft part 61D (hereinafter, also simply referred to as "shaft adjacent portion 62") can be bent and deformed toward the inside and outside of the operation member 50D via the slit 62a.

[0115] In addition, an inner bending restricting portion 77 is disposed inside the pair of shaft adjacent portions 62, 62 to restrict bending deformation toward the inside of the operation member 50D (here, bending deformation toward the inside of the transmission wall portion 57). Fig.23 As shown in the figure, the inner bending restriction portion 77 in a substantially trapezoidal frame shape to be inserted into the transmission wall portion 57 is erected from the back side of the cover member 70D, and the inner bending restriction portion 77 is arranged on the inner side of the pair of shaft adjacent portions 62, 62, thereby restricting the bending deformation of the pair of shaft adjacent portions 62, 62 toward the inner side of the transmission wall portion 57. It should be noted that the lock core 67 may be provided as a restriction on the bending deformation of the pair of shaft adjacent portions 62, 62 toward the inner side of the transmission wall portion 57 instead of the inner bending restriction portion 77 as described above.

[0116] In addition, the pair of wall portions 75, 75 of the cover member 70D are arranged outside the pair of shaft adjacent portions 62, 62, and restrict the bending deformation of the pair of shaft adjacent portions 62, 62 to the outside of the transmission wall portion 57 (see Fig.25 ).

[0117] In addition, as a structure provided with the slit, in addition to the above-mentioned structure, the following structures (1) to (5) may be adopted.

[0118] That is, on the premise that the shaft portion is in a protrusion shape and the shaft supporting portion is in a groove shape (the same applies to the above-mentioned structure), the following structure can be set: (1) a slit is formed at a position adjacent to the shaft portion, and a slit is also formed at a position adjacent to the shaft supporting portion, resulting in a structure in which both the slit adjacent portion of the shaft portion and the slit adjacent portion of the shaft supporting portion can bend and deform; (2) a slit is not formed at a position adjacent to the shaft portion, but a slit is formed at a position adjacent to the shaft supporting portion, resulting in a structure in which only the slit adjacent portion of the shaft supporting portion can bend and deform, etc.

[0119] In addition, on the premise that the shaft portion is groove-shaped and the shaft supporting portion is protrusion-shaped, the following structures can also be set: (3) a slit is formed at a position adjacent to the shaft portion, and a slit is not formed at a position adjacent to the shaft supporting portion, resulting in a structure in which only the slit adjacent portion of the shaft portion can bend and deform; (4) a slit is formed at a position adjacent to the shaft portion, and a slit is also formed at a position adjacent to the shaft supporting portion, resulting in a structure in which both the slit adjacent portion of the shaft portion and the slit adjacent portion of the shaft supporting portion can bend and deform; (5) a slit is not formed at a position adjacent to the shaft portion, but a slit is formed at a position adjacent to the shaft supporting portion, resulting in a structure in which only the slit adjacent portion of the shaft supporting portion can bend and deform, 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 wall portions 35, 35, but it can also be 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 wall portions.

[0121] It should be noted that, in the case where the slit adjacent portion of the shaft portion or the slit adjacent portion of the shaft support portion is configured to bend and deform toward the inside or outside of the operating member or the base member according to the above-mentioned structures (1) to (5), the inner bending limiting portion and the lock core are arranged on the inner side of the slit adjacent portion of the shaft portion and the slit adjacent portion of the shaft support portion, and the outer bending limiting portion is arranged on the outer side of the slit adjacent portion of the shaft portion and the slit adjacent portion of the shaft support portion. That is, the following structures are obtained: (a) a structure having only the inner bending limiting portion or the lock core; Figure 22 to Figure 25 (b) a structure having only an outer flexure limiting portion; (c) a structure having both an inner flexure limiting portion or a lock core and an outer flexure limiting portion.

[0122] Furthermore, in this embodiment, if Fig.24 As shown by the arrow F4, first, the operating member 50D is assembled to the base member 30. In this case, the pair of transmission wall portions 57, 57 are inserted into the inner side of the pair of limiting wall portions 35, 35, at which time, the top ends of the pair of shaft portions 61D, 61D are pressed by the inner surfaces of the pair of limiting wall portions 35, 35, and the pair of shaft portion adjacent portions 62, 62 are inserted while being bent and deformed inward. Moreover, when the pair of shaft portions 61D, 61D reaches the pair of shaft support portions 37, 37, the pair of shaft portion adjacent portions 62, 62 are elastically restored, and the pair of shaft portions 61D, 61D are inserted into the pair of shaft support portions 37, 37, and the operating member 50D is assembled to the base member 30.

[0123] Then, if Fig.24As shown by the arrow F5, the cover member 70D is attached to the operating member 50D. That is, the top end 52B of the operating plate portion 51 is inserted into and locked in the locking frame portion 72a of the cover plate portion 71, and the locking projections 73a, 73a of the cover plate portion 71 are locked on 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 front side of the operating plate portion 51. At this time, as shown in FIG. Fig.25 As shown, the inner bending restriction portion 77 provided on the cover member 70D is inserted and arranged inside the pair of shaft adjacent portions 62, 62, thereby restricting the bending deformation of the pair of shaft adjacent portions 62, 62 toward the inside of the operation member 50D, that is, toward the inside of the transmission wall portion 57.

[0124] As described above, in the present embodiment, a slit is formed in the operating load transfer wall portion and / or a pair of deformation limiting wall portions at a position adjacent to the shaft portion and / or the shaft supporting portion, through which the adjacent portion of the shaft portion and / or the adjacent portion of the shaft supporting portion can bend and deform toward 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 portion 61D, and the shaft portion adjacent portion 62 can bend and deform toward the inside and outside of the transfer wall portion 57 of the operating member 50D through the slit 62a), thereby improving the assembly operability of the operating member 50 relative to the base member 30.

[0125] In addition, there is an inner bending limiting portion or a lock core disposed on the inner side of the adjacent portion of the shaft portion or the shaft support portion, which limits the bending deformation of the operation load transfer wall portion inward, and / or an outer bending limiting portion disposed on the outer side of the adjacent portion of the shaft support portion or the shaft portion, which limits the bending deformation of a pair of deformation limiting walls inward. Here, the inner bending limiting portion 77 is disposed on the inner side of a pair of shaft portion adjacent portions 62, 62. 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 bending deformation of the slit adjacent portion of the shaft portion or the slit adjacent portion of the shaft support portion formed by the slit can be limited by the inner bending limiting portion or the lock core, and the outer bending limiting portion, so that 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-mentioned embodiments, and various modified embodiments can be implemented within the scope of the gist of the present invention, and such embodiments are also included in the scope of the present invention.
