[0007] Patent Document 1: Japanese Patent Application Publication No. 2019-23379 Summary of the invention

[0008] Problems to be solved by the invention

[0009] In the case of the locking device of Patent Document 1, when the user rotates the operating member in a direction away from the base member, the anti-rotation portion provided on the operating member is hooked on the base member at a predetermined rotation position, thereby limiting the rotation of the operating member. Then, the operating load is transmitted to the transmission portion via the anti-rotation portion and transmitted to the base end side of the transmission portion.

[0010] At this time, the operating load is concentrated on the connecting portion between the base end of the transmission part and the base (the boundary portion between the base end of the transmission part and the base), and the transmission part and the base may be damaged. Figure 2 As shown, the connection portion between the transmission portion and the base portion is reinforced by a plurality of reinforcing ribs in a substantially triangular plate shape.

[0011] However, when the operation member is rotated maximally relative to the base member by these reinforcing ribs, damage to the transmission portion, the base portion, and the like may not be sufficiently suppressed.

[0012] Therefore, an object of the present invention is to provide a locking device for an opening and closing body, which can sufficiently suppress damage to an operating member when the operating member is rotated maximally relative to a base member.

[0013] Solutions for solving problems

[0014] In order to achieve the above-mentioned purpose, the present invention is a locking device for an opening and closing body, which is a locking device for an opening and closing body installed on an opening part of a fixed body in an openable and closable manner, characterized in that it comprises: a locking portion provided on one of the fixed body or the opening and closing body; a locking member arranged on the other of the fixed body or the opening and closing body to engage / disengage with 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 an axis support portion to operate the locking member, the operating member comprising: an operating plate portion extending in a plate shape; an operating portion provided on the operating plate portion; a first load transmission wall portion extending from the back of the operating plate portion side protrusion; a stop portion, which is connected to the first load transfer wall portion; and a second load transfer wall portion, which is arranged on the back side of the operating panel portion, the base end portion of the second load transfer wall portion is connected to the first load transfer wall portion and / or the stop portion, and the second load transfer wall portion has: an extension portion, which has a portion extending obliquely toward the operating panel portion; and a connecting portion, which connects the extension portion and the operating panel portion, the base member has a stop receiving portion, and the stop receiving portion can abut against the stop portion to limit the rotation of the operating member, and a gap is formed between the first load transfer wall portion, the extension portion of the second load transfer wall portion and the connecting portion and the operating panel portion.

[0015] Effects of the Invention

[0016] According to the present invention, when the operating portion is operated to rotate the operating member to the maximum with respect to the base member, the stopper abuts against the stopper receiving portion, so that the stopper bears the operating load. A portion of the operating load is transmitted to the operating plate portion along one direction of the first load transmission wall portion or the second load transmission wall portion, and the remaining portion of the operating load is transmitted to the operating plate portion along the other direction of the first load transmission wall portion or the second load transmission wall portion. As a result, the operating load can be dispersed in two paths, namely, the path on the first load transmission wall portion side and the path on the second load transmission wall portion side, so that the rigidity of the operating member can be improved, thereby fully suppressing the damage of the operating member when it is operated.

[0038] It should be noted that, in this embodiment, Figure 2 , Figure 7 As shown, the support protrusion 36 provided on the base member 30 and the support groove portion 59 provided on the operation member 50 form the “shaft support portion” of the present invention.

[0039] like Figure 1 As shown, in this embodiment, hole-shaped locking portions 3, 3 are provided on both inner surfaces of the opening portion 2 of the fixing body 1 in the width direction.

[0040] In addition, if Figure 1 As shown, the opening and closing body 4 of this embodiment is composed of an outer member 5 arranged inside the vehicle compartment and an inner member 6 arranged on the back side of the outer member 5. A concave accommodation recess 7 having a transversely long rectangular shape is formed on one side in the width direction of the outer member 5 and above it.

[0041] The base member 30 and the operating member 50 are accommodated in the accommodation recess 7 (see Figure 8). In addition, a mounting hole 8 in the shape of an elongated hole is formed in the bottom 7a of the accommodating recessed portion 7. The base member 30 is mounted from the front side of the mounting hole 8.

[0042] It should be noted that the above-mentioned "front side" or "surface side" refers to a side or surface located in the direction of opening of the opening and closing body from the opening of the fixed body of the vehicle or the like. In addition, when the fixed body is provided in the vehicle, the side of the vehicle interior space is set as the "front side" or "surface side". Moreover, the "back side" or "back side" refers to the side opposite to the "front side" or "surface side", that is, a side or surface located in the direction of closing of the opening and closing body.

[0043] In addition, the above-mentioned “front side”, “surface side”, “back side” and “rear side” have the same meaning not only for the mounting hole but also for other members (base member 30, operation member 50, etc.) described below.

[0044] like Figure 1 As shown, the inner member 6 is in the shape of a box with an upper opening. In addition, a locking arrangement recess 6a having a horizontally long concave shape is provided on the surface side (front side) of the inner member 6 that is arranged opposite to the outer member 5 and on the upper part thereof, and the locking arrangement recess 6a arranges the pair of locking members 20, 20 to be slidable. Locking through holes 6b, 6b are respectively formed on both sides of the long dimension direction of the locking arrangement recess 6a.

[0045] Furthermore, a rotation member support portion 9 for rotationally supporting the rotation member 25 is provided protrudingly from the front surface side of the bottom surface of the lock placement recess 6 a .

[0046] In addition, if Figure 1 , Fig.10 As shown, the pair of locking members 20, 20 of 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 3 (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 .

[0047] The rotating member 25 has a substantially rhombus shape with a long axis (see Fig.10 ), the middle part in the longitudinal direction is rotatably supported by the rotating member support part 9, and the two 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.

[0048] In addition, a torsion spring 27 is attached to the rotating member 25. Fig.10 The rotating member 25 is rotated and forced in the direction of arrow A, and 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 3, 3 ( 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 6b, 6b provided in the locking arrangement recess 6a.

[0049] Next, refer to Figure 2 as well as Figure 7 to Figure 9 The base member 30 will be described in detail.

[0050] 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 walls 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 walls 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 walls 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.

[0051] It should be noted that, in the following description, the direction in which the bottom wall 31 extends is referred to as “extension direction X1”, and the direction orthogonal to the extension direction X1 is referred to as “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).

[0052] The bottom wall 31 is formed with a slide groove 35, and the slide groove 35 is configured to receive the operating rod 65 (see FIG. 1 ) of the operating member 50. Figure 2 ) is collected in a slidable and movable manner.

[0053] In addition, a substantially arc-shaped support protrusion 36 is provided protruding outward from the outer surface of each side wall 32 above (opposite to the bottom wall 31) and near the connecting wall 34. Each support protrusion 36 is inserted from the inner side of the support groove 59 of the operating member 50, so that the operating member 50 is rotatably supported on the base member 30.

[0054] Furthermore, each side wall 32 is provided at a position close to the bottom wall 31 with: an elastic engaging piece 37 formed to be able to bend and deform through a U-shaped slit 37a; and a rib 38 protruding outward from a position adjacent to the elastic engaging piece 37. The elastic engaging piece 37 is engaged with the back side periphery of the mounting hole 8, and the rib 38 is engaged with the front side periphery of the mounting hole 8.

[0055] In addition, a pair of hooks 39, 39 are provided protruding from the bottom wall 31 side of the connecting wall 33 and on both sides of the width direction Y1. In addition, a pair of elastic engaging claws 40, 40 are provided from the bottom wall 31 side of the connecting wall 34 and on both sides of the width direction Y1. Figure 8 As shown, a pair of hooks 39 , 39 and a pair of elastic engaging claws 40 , 40 are engaged with the rear peripheral edge of the mounting hole 8 .

[0056] In addition, the base member 30 has a stopper receiving portion 43, and the stopper receiving portion 43 can be abutted by the stopper portion 63 provided on the operation member 50 (see Fig. 9 ), thereby restricting the rotation of the operating member 50.

[0057] In the present embodiment, a notch 41 is cut out from the bottom wall 31 toward the top opening in the middle portion of the connecting wall 33 in the width direction Y1, and a stop receiving portion 43 is provided on the side of the connecting wall 33 opposite to the bottom wall 31 through the notch 41.

[0058] Furthermore, a rubber damper 45 (see FIG. 1 ) is attached to a corner portion of one end side of the base member 30 in the extending direction X1. Figure 2 The damper 45 can reduce the impact sound when the operating portion 53 of the operating member 50 is rotated in a direction close to the base member 30 and the bottom 7a of the accommodating recess 7. In addition, a coil spring 47 is arranged at the corner of the other end side of the base member 30 in the extension direction X1.

[0059] Next, refer to Figure 2 to Figure 9 The operation member 50 will be described below.

[0060] The operating member 50 includes: an operating plate portion 51 extending in a plate shape; an operating portion 53 provided on the operating plate portion 51; a first load transfer wall portion 60 (hereinafter, also referred to as the "first transfer wall portion 60") protruding from the back side of the operating plate portion 51 (the side opposite to the base member 30); a stop portion 63 connected to the first transfer wall portion 60; and a second load transfer wall portion (hereinafter, also referred to as the "second transfer wall portion 70") provided on the back side of the operating plate portion 51.

[0061] It should be noted that, in the present invention, the stopper 63 and the first transmission wall 60 are connected to each other, which means that the stopper 63 and the first transmission wall 60 are directly connected to each other and formed as one body.

[0062] Furthermore, the operation member 50 of the present embodiment is in an elongated shape as a whole that is long in one direction, and includes a substantially elongated plate-shaped operation plate portion 51 that extends in a plate-like shape by a predetermined length.

[0063] It should be noted that in the following description, the direction in which the operation plate portion 51 extends is referred to as the "extension direction X2". Figure 7 The direction parallel to the axial direction C (direction along the axis) of the shaft support portion (support protrusion 36 and support groove portion 59) shown in the figure refers to the "width direction" of the present invention, which is set as "width direction Y2". In addition, the "width direction Y2" can also be said to be a direction orthogonal to the extension direction X2. It should be noted that the extension direction X2 and the width direction Y2 also have the same meaning in the operating member 50 itself and the parts other than the operating plate portion 51 that constitutes the operating member 50 (the second transmission wall portion 70, etc.).

[0064] In addition, an operating portion 53 is provided on one end (top end) side of the operating plate portion 51 in the extension direction X2, and the operating portion 53 is a portion for the operator to hold and operate when the operating member 50 is rotated. In addition, a partition wall portion 54 is provided upright from the back side of the operating plate portion 51 to separate the operating plate portion 51 and the operating portion 53. That is, the operating portion 53 is formed in the range from the position where the partition wall portion 54 is provided upright to one end of the extension direction X2 in the operating plate portion 51.

[0065] In addition, if Figure 5 As shown, the partition wall portion 54 and the flat surface 61 of the first transmission wall portion 60 are arranged opposite to each other with a predetermined interval therebetween, and both sides of the partition wall portion 54 in the width direction Y2 are connected to a pair of side walls 57, 57 described below. Figure 3 As shown, a base end portion 54 a of the partition wall portion 54 in the rising direction is connected to the back side of the operation plate portion 51 .

[0066] Furthermore, a circular-hole-shaped key cylinder insertion hole 55 for inserting the key cylinder 69 is formed on the other end portion (base end portion) side of the operation plate portion 51 in the extending direction X2.

[0067] A pair of side walls 57, 57 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, a supporting groove portion 59 in the shape of a substantially circular arc groove is formed on the base end side of each side wall 57 in the extension direction X2.

[0068] Furthermore, the pair of support protrusions 36 , 36 provided on the base member 30 are inserted from the inner sides of the pair of support grooves 59 , 59 , whereby the operation member 50 is rotatably supported by the base member 30 .

[0069] As a result, if Figure 8 and Fig. 9As shown, the operation member 50 rotates relative to the base member 30 with the shaft support portion as a rotation fulcrum so that the operation portion 53 approaches or moves away from the base member 30 and the bottom 7 a of the accommodating recess 7 .

[0070] In addition, the coil spring 47 is interposed in a compressed state between the other end portion of the operation member 50 in the extending direction X2 and the other end portion of the base member 30 in the extending direction X1 (see Figure 8 ).

[0071] Therefore, if Fig. 9 As shown, in a state where the operating member 50 is rotated relative to the base member 30 in a manner of holding the operating portion 53 away from the base member 30 and the bottom 7a of the accommodating recess 7, when the operator removes his hand from the operating portion 53, force is applied to rotate the operating portion 53 in a direction approaching the base member 30 and the bottom 7a of the accommodating recess 7.

[0072] Furthermore, a substantially cylindrical first transmission wall portion 60 through which the key cylinder 69 can be inserted is protruded (or protrudedly provided) from the back side of the operation plate portion 51 and the back side periphery of the key cylinder insertion hole 55 .

[0073] The first transmission wall portion 60 has the following structure: Fig. 9 As shown, when the operating member 50 is rotated to the maximum relative to the base member 30 and the stop portion 63 abuts against the stop receiving portion 43 to limit the rotation of the operating member 50, the first transmission wall portion 60 transmits the operating load F input via the stop portion 63 to the operating plate portion 51 and the second transmission wall portion 70.

[0074] Furthermore, a flat surface 61 having a flat surface shape is formed on the outer surface of the first transmission wall portion 60 on one end side facing the extending direction X2.

[0075] A stopper 63 is provided to protrude from the outer surface of the first transmission wall 60 at one end in the extending direction X2 and at the top end of the first transmission wall 60 . The stopper 63 is formed integrally and continuously with the first transmission wall 60 .

[0076] And, if Fig. 9 As shown, when the operating part 53 is rotated maximally relative to the base member 30 in a direction away from the base member 30 and the bottom 7a of the accommodating recess 7 by holding the operating part 53 to resist the applied force of the coil spring 47, the stop part 63 abuts against the stop receiving part 43, thereby limiting the further rotation of the operating member 50.

[0077] In addition, if Figure 3 As shown in FIG. 1 , an operation lever 65 is provided standing from the back side near the other end (base end) of the operation plate portion 51 in the extending direction X2.

[0078] A portion of the operating rod 65 is connected to a radially opposite position of the stopper-forming portion of the first transmission wall portion 60, and the operating rod 65 is erected higher than the protruding direction top end portion of the first transmission wall portion 60. The operating rod 65 passes through the back side of the sliding groove 35 of the base member 30 and enters the frame-shaped portion 23 of the locking member 20 on one side.

[0079] When the operating portion 53 of the operating member 50 is rotated in a direction away from the base member 30 and the bottom 7a of the accommodating recess 7, the operating rod 65 presses the inner surface of the frame portion 23 of one locking member 20, thereby causing the top ends 22, 22 of the pair of locking members 20, 20 to slide in a direction not to engage with the pair of locking portions 3, 3 of the fixed body 1 via the rotating member 25 (see Fig.11 ).

[0080] In addition, if Figure 3 , Figure 4 As shown, a damper 45 (see FIG. 1 ) is protrudingly provided on the back side of the operation plate portion 51 and on one side in the width direction Y2 and close to the partition wall portion 54. Figure 2 ) is a damper abutment portion 67 which is in the shape of a roughly cylindrical protrusion and abuts against the damper.

[0081] The damper contact portion 67 is a portion that contacts the damper 45 attached to the base member 30 when the coil spring 47 biases the operation portion 53 to rotate in a direction approaching the base member 30 and the bottom 7 a of the accommodating recess 7 .

[0082] Furthermore, the base end portion 71 of the second transmission wall portion 70 is connected to the stop portion 63 and / or the first transmission wall portion 60, and the second transmission wall portion 70 has: an extension portion 73 having a portion extending obliquely toward the operating plate portion 51; and a connecting portion connecting the extension portion 73 and the operating plate portion 51.

[0083] In the present embodiment, the base end portion 71 of the second transmission wall portion 70 is connected to the connection portion (the boundary portion between the first transmission wall portion 60 and the stopper portion 63) of the first transmission wall portion 60 and the stopper portion 63. The first extension portion 75 extends obliquely from the base end portion 71 toward one end of the extension direction X2 of the operation plate portion 51. In addition, the second extension portion 76 extends from the top end of the first extension portion 75 in the extension direction in parallel with the surface direction of the operation plate portion 51 (the direction along the surface of the operation plate portion 51).

[0084] Furthermore, the leading end 77 of the second extending portion 76 in the extending direction is connected to the base end 54a of the partition wall portion 54. That is, in the present embodiment, the base end 54a of the partition wall portion 54 forms the "connecting portion" of the present invention.

[0085] The first extending portion 75 described above forms the “portion extending obliquely toward the operation panel portion” of the present invention. Furthermore, the first extending portion 75 and the second extending portion 76 form the “extending portion 73” of the present invention.

[0086] Furthermore, the extending portion 73 is formed with a constant width from the base end portion 71 to the tip end 77 (the length in the width direction Y2 is constant).

[0087] Furthermore, the outer surface 78 of the leading end portion in the extending direction of the second extending portion 76 is raised so as to be higher from the back surface of the operation plate portion 51 than the outer surface of the base end portion in the extending direction.

[0088] Furthermore, when the damper 45 is attached to the base member 30 as in the present embodiment, Figure 8 As shown, when the coil spring 47 is biasing the operating portion 53 toward the base member 30 and the bottom 7a of the accommodating recess 7, the outer surface 78 and the front end surface of the connecting wall 33 of the base member 30 are arranged opposite to each other with a small gap therebetween.

[0089] On the other hand, when the damper 45 is not attached to the base member 30 , the outer surface 78 abuts against the front end surface of the connecting wall 33 of the base member 30 while the coil spring 47 is urging the operating portion 53 to rotate in a direction approaching the base member 30 .

[0090] In addition, if Figure 3 , Figure 5 , Figure 6 as well as Fig. 9 As shown, in the locking device 10 , a gap K is formed between the first transmission wall portion 60 , the extending portion 73 and the connecting portion of the second transmission wall portion 70 , and the operation plate portion 51 .

[0091] Moreover, if Figure 5 and Figure 6 As shown, a side wall portion 80 that connects the operation plate portion 51 and the first transmission wall portion 60 is provided on one side portion of the second transmission wall portion 70 in the width direction Y2.

[0092] The side wall portion 80 of the present embodiment is a structure that connects the flat surface 61 of the first transmission wall portion 60, the first extension portion 75 and the second extension portion 76 that constitute the extension portion 73, the partition wall portion 54, and the operation plate portion 51. Figure 6 As shown, a thick portion 81 having a wall thickness greater than that of a base end portion connected to the operation plate portion 51 is provided at a portion of the side wall portion 80 on the flat surface 61 side of the first transmission wall portion 60 .

[0093] Furthermore, in relation to the above-mentioned side wall portion 80 , the above-mentioned gap K has the following structure.

[0094] That is, the gap K in this embodiment is surrounded by the flat surface 61 of the first transmission wall portion 60, the first extension portion 75 and the second extension portion 76 constituting the extension portion 73, the partition wall portion 54, the operating plate portion 51 and the side wall portion 80, one side portion of the operating plate portion 51 in the width direction Y2 is closed by the side wall portion 80, and the other side portion of the operating plate portion 51 in the width direction Y2 is open.

[0095] Furthermore, connecting ribs 83 and 84 connecting the extension portion 73 and the operation plate portion 51 are provided closer to the first transmission wall portion 60 than the connecting portion of the tip of the extension portion 73 (the tip 77 of the second extension portion 76 ) with the partition wall portion 54 .

[0096] In the case of this embodiment, if Figure 3 , Figure 8 as well as Fig. 9 As shown, the connecting portion of the first extension portion 75 and the second extension portion 76 (the boundary portion of the first extension portion 75 and the second extension portion 76) and the operation plate portion 51 are connected by a connecting rib 83. In addition, the extending direction of the second extension portion 76 and the operation plate portion 51 are connected by a connecting rib 84.

[0097] Each connecting rib 83, 84 is provided in a manner perpendicular to the surface direction of the back surface of the operation plate portion 51 (the direction along the surface of the back surface of the operation plate portion 51). In addition, each connecting rib 83, 84 extends over the entire region of the extension portion 73 in the width direction Y2, and one end of each connecting rib 83, 84 in the width direction Y2 is connected to the side wall portion 80.

[0098] It should be noted that the above-mentioned connecting ribs 83 and 84 also form the “connecting portion” of the present invention. That is, in the case of the present embodiment, the connecting ribs 83 and 84 and the base end portion 54a of the above-mentioned partition wall portion 54 form the “connecting portion” of the present invention.

[0099] Furthermore, the connecting portion is formed to be thinner than the extending portion 73 .

[0100] In the case of this embodiment, if Fig. 9 As shown, in the longitudinal section ( Figure 7 When the locking device 10 is observed in a cross section (a cross section taken along the G-G line of sight), the thickness T1 of the base end portion 54a of the partition wall portion 54 constituting the connecting portion and the connecting ribs 83 and 84 is formed in a manner thinner than the thickness T2 of the first extension portion 75 and the second extension portion 76 constituting the extending portion 73.

[0101] In addition, the thickness T1 of the connection portion refers to the size in the surface direction of the back surface of the operation panel portion 51. On the other hand, the thickness T2 of the extension portion 73 refers to the size in the direction intersecting the surface direction of the back surface of the operation panel portion 51. That is, the thickness T2 of the second extension portion 76 is the size in the direction orthogonal to the surface direction of the back surface of the operation panel portion 51, and the thickness T2 of the first extension portion 75 is the size in the direction obliquely intersecting the surface direction of the back surface of the operation panel portion 51.

[0102] Moreover, if Figure 3 As shown in the partially enlarged stereoscopic diagram, when the surface area of ​​the second transmission wall portion 70 when observed from the width direction Y2 is set to S1 (the area surrounded by the single-dash hatched line), and the surface area of ​​the second transmission wall portion 70 when observed from the thickness direction is set to S2 (the area surrounded by the double-dash hatched line), S1<S2.

[0103] It should be noted that the above structure can also be rephrased as follows. That is, the surface area of ​​the second transmission wall portion 70 when viewed from the back surface of the operation plate portion 51 can be referred to as "S2", and the surface area of ​​the second transmission wall portion 70 when viewed from the side can be referred to as "S1". In this case, S2 is also set to be larger than S1.

[0104] In the locking device 10 described above, when the operating portion 53 is operated to rotate the operating member 50 relative to the base member 30 so that the stopper 63 abuts against the stopper receiving portion 43, the operating load F (see Fig. 9 ) is input to the stopper 63.

[0105] Furthermore, it is configured that a part of the operation load F is transmitted along the one-way operation plate portion 51 in the first transmission wall portion 60 or the second transmission wall portion 70, and the remaining part of the operation load F is transmitted along the other-way operation plate portion 51 in the first transmission wall portion 60 or the second transmission wall portion 70, so that the operation load F is dispersed. In addition, there are the following (1) to (3) as load dispersion schemes for the operation load F.

[0106] That is, in the case of a structure in which the base end portion 71 of the second transmission wall portion 70 is connected to the first transmission wall portion 60 and the stop portion 63 as in the present embodiment, (1) the above-mentioned operating load F is transmitted from the stop portion 63 to both the first transmission wall portion 60 and the second transmission wall portion 70 simultaneously or approximately simultaneously (approximately without time lag), thereby dispersing the operating load F.

[0107] In addition, in the case where the base end portion 71 of the second transmission wall portion 70 is connected only to the first transmission wall portion 60, (2) the above-mentioned operating load F is first transmitted from the stop portion 63 to the first transmission wall portion 60, and then transmitted to the second transmission wall portion 70 via the first transmission wall portion 60, thereby dispersing the operating load F.

[0108] Moreover, in the case where the base end portion 71 of the second transmission wall portion 70 is connected only to the stop portion 63, (3) after the above-mentioned operating load F is transmitted from the stop portion 63 to the second transmission wall portion 70, it is transmitted to the first transmission wall portion 60 at a later timing or substantially simultaneously, thereby dispersing the operating load F.

[0109] The method of distributing the operation load F in this embodiment will be described in more detail.

[0110] That is, when Figure 8 When the operating member 50 is rotated as far as possible relative to the base member 30 by holding the operating portion 53 and moving away from the base member 30 and the bottom 7a of the receiving recess 7 as shown by the arrow F′, Fig. 9 As shown, the stopper 63 abuts against the stopper receiving portion 43, thereby restricting further rotation of the operation member 50. Then, the stopper 63 receives the operation load F from the stopper receiving portion 43.

[0111] At this time, in this embodiment, the base end portion 71 of the second transmission wall portion 70 is connected to both the first transmission wall portion 60 and the stop portion 63, so the operating load F is transmitted to the first transmission wall portion 60 and the second transmission wall portion 70 simultaneously or approximately simultaneously, so that the operating load F is dispersed (load dispersion scheme (1) of paragraph 0084).

[0112] That is, Fig. 9 As shown, when the connecting portion (boundary portion) of the base end portion 71 of the first transmission wall portion 60 and the second transmission wall portion 70 is set as the load branch portion P, the operating load F is branched at the load branch portion P, a part of which is transmitted to the first transmission wall portion 60, and the remaining part is transmitted to the second transmission wall portion 70.

[0113] Specifically, the operating load F is transmitted by two paths L1 and L2, namely, a first path L1 along the first transmission wall portion 60 (a path mainly along the protruding direction of the first transmission wall portion 60 and passing through the flat surface 61) and a second path L2 along the second transmission wall portion 70 (a path passing through the inclined path of the first extension portion 75 and a path passing through the second extension portion 76 and parallel to the surface direction of the operating panel portion 51).

[0114] In addition, in the locking device 10, if Figure 5 , Figure 6 as well as Fig. 9As shown in FIG. 1 and FIG. 2 , a gap K is formed between the first transmission wall portion 60, the extension portion 73 of the second transmission wall portion 70, and the connecting portion and the operation plate portion 51, so that the load dispersion of the above-mentioned operation load F becomes reliable. That is, by forming the above-mentioned gap K, the operation load F once transmitted to the first transmission wall portion 60 side and the operation load F once transmitted to the second transmission wall portion 70 side can be prevented from merging again.

[0115] Then, the operation load F transmitted to the first transmission wall portion 60 is mainly transmitted to the operation plate portion 51 along the flat surface 61 of the first transmission wall portion 60 (see the first path L1 ).

[0116] On the other hand, the operation load F transmitted to the second transmission wall portion 70 is transmitted to the first extension portion 75 via the base end portion 71 (see the second path L2). Thereafter, a portion of the operation load F is transmitted to the operation plate portion 51 via the connection rib 83 (see the second path L2a), and the remaining portion of the operation load F is transmitted to the second extension portion 76.

[0117] Furthermore, part of the operation load F transmitted to the second extending portion 76 is transmitted to the operation plate portion 51 via the connecting rib 84 (see the second path L2 b ), and the remainder of the operation load F is further transmitted to the partition wall portion 54 along the second extending portion 76 .

[0118] Then, part of the operation load F transmitted to the partition wall portion 54 is transmitted to the operation plate portion 51 via the base end portion 54a of the partition wall portion 54 (refer to the second path L2c), and the operation load F is transmitted to both sides of the partition wall portion 54 in the width direction Y2, and is transmitted to the pair of side walls 57, 57 (refer to Figure 5 The second path L2d shown).

[0119] Thus, in the case of the present embodiment, the operating load F that branches off from the load branch portion P and is transmitted to the second transmission wall portion 70 is mainly transmitted to the operating plate portion 51 along the second path L2 formed by the first extension portion 75 and the second extension portion 76, and branches off and is transmitted to the operating plate portion 51 along multiple paths (second paths L2a, L2b, L2c, L2d) until it reaches the top end 77 in the extension direction of the extension portion 73.

[0120] (Variation Example)

[0121] The shape, structure, layout, etc. of the locking portion, locking member, base member, operating member and the various parts constituting each member (for example, the first load transfer wall portion, the second load transfer wall portion, etc. constituting the operating member) of the locking device constituting the opening and closing body in the present invention are not limited to the above-mentioned scheme.

[0122] 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.

[0123] Moreover, in this embodiment, the mounting hole 8 is formed in the opening and closing body 4, and the locking member 20 is slidably arranged on the opening and closing body 4, but the mounting hole can also be formed in the fixed body and the locking member can be slidably arranged on the fixed body side.

[0124] In addition, the locking portion 3 in this embodiment is in the shape of a hole, but as a locking portion, it can also be not a hole shape, but a concave shape, a protrusion shape, a frame shape, etc., and the locking portion can also be provided on the opening and closing body instead of being provided on the opening portion of the fixed body.

[0125] 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 3 (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 be used.

[0126] In addition, in this embodiment, when the operating member 50 is rotated as described above, the locking member 20 on one side is caused to slide, and the locking member 20 on the other side is caused to slide via the rotating member 25, but it can also be configured as: the rotating member is rotated by the rotation of the operating member, thereby causing a pair of locking members to slide (this scheme is adopted in the third embodiment described later).

[0127] Furthermore, the opening and closing body 4 in the present embodiment is composed of the outer member 5 and the inner member 6, but the opening and closing body may be formed of a single plate material.

[0128] In addition, in the present embodiment, the operating member 50 is a so-called horizontal push-pull handle in which the operating portion 53 is provided at one end portion in the extending direction of the operating plate portion 51 and is mounted to the base member 30 in a manner that can rotate in the horizontal direction. However, as the operating member, it can also be set as a so-called vertical push-pull handle in which the operating portion is provided above or below the operating plate portion in advance and the operating member is mounted to the base member in a manner that can rotate in the vertical direction.

[0129] Furthermore, in the present embodiment, the key cylinder 69 is inserted and arranged inside the first transmission wall portion 60. However, a configuration may be adopted in which the key cylinder is not inserted inside the first load transmission wall portion (this will be described in a second embodiment described later).

[0130] In addition, in the case of the present embodiment, the shaft support portion is composed of the support protrusion 36 provided on the base member 30 and the support groove portion 59 provided on the operating member 50. However, as the shaft support portion, for example, it is also possible to be composed of a shaft portion protruding from the operating member and a hole, a recessed portion, etc. formed in the base member and supporting the shaft portion, or it is also possible to form a shaft support hole in the base member and the operating member and insert a separate support shaft into the shaft support hole.

[0131] Furthermore, in the case of this embodiment, the base end portion 71 of the second load transmission wall portion 70 is connected to the first load transmission wall portion 60 and the stopper portion 63. However, the base end portion of the second load transmission wall portion may be connected only to the first load transmission wall portion (this will be described in the third embodiment described later) or only to the stopper portion. It should be noted that the load distribution scheme of the operating load in these cases is as described in paragraphs 0085 and 0086.

[0132] (Effect)

[0133] Next, the effects of the locking device 10 having the above-described configuration will be described.

[0134] In the locking device 10, the opening and closing body 4 is closed from the opening portion 2 of the fixed body 1 from the open state of the opening and closing body 4, and the top ends 22, 22 of the pair of locking members 20, 20 are engaged with the locking portions 3, 3 of the fixed body 1, thereby locking the opening and closing body 4 in the closed state (refer to Fig.10 ).

[0135] From this state, if Fig. 9 As shown in FIG. 1 , when the operating portion 53 is rotated in a direction away from the base member 30 and the bottom 7a of the accommodating recess 7, as shown in FIG. Fig.11 As shown, the top end 22 of one locking member 20 is pulled in a direction not engaged with the locking portion 3 against the rotational force of the rotating member 25, and the top end 22 of the other locking member 20 is pulled in a direction not engaged with the locking portion 3 in conjunction with the rotating member 25. As a result, the lock of the opening and closing body 4 in the closed state can be released, so that the opening and closing body 4 can be opened from the opening portion 2 of the fixed body 1.

[0136] Furthermore, in the locking device 10, a second transmission wall portion 70 is provided on the operating member 50, and the base end portion 71 of the second transmission wall portion 70 is connected to the first transmission wall portion 60 and the stop portion 63, and the second transmission wall portion 70 has: an extension portion 73, having a portion (a first extension portion 75 and a second extension portion 76) extending obliquely toward the operating plate portion 51; and a connecting portion (a base end portion 54a of the partition wall portion 54 and connecting ribs 83, 84), which connects the extension portion 73 and the operating plate portion 51, and in addition, a gap K is formed between the first transmission wall portion 60, the extension portion 73 of the second transmission wall portion 70 and the connecting portion and the operating plate portion 51.

[0137] Therefore, as described in paragraphs 0088 to 0097, the operating member 50 is rotated as far as possible relative to the base member 30, so that Fig. 9 The stop portion 63 shown abuts against the stop receiving portion 43, whereby the operating load F borne by the stop portion 63 is branched from the load branch portion P, a portion of which is transmitted to the first transfer wall portion 60 (refer to the first path L1), and the remaining portion is transmitted to the second transfer wall portion 70, and then transmitted to the operating plate portion 51 through the connecting portion (the base end portion 54a of the partition wall portion 54 and the connecting ribs 83, 84) (refer to the second paths L2, L2a, L2b, L2c, L2d).

[0138] In this way, in the locking device 10, the operating load F applied to the operating member 50 side via the stop receiving portion 43 and the stop portion 63 can be distributed in the two paths L1 and L2, namely the first path L1 along the first transmission wall portion 60 side and the second path L2 along the second transmission wall portion 70 side, and transmitted to the operating plate portion 51, rather than being transmitted to the operating plate portion 51 in one path.

[0139] Therefore, the operation load F is not easily concentrated on the connection portion between the base end of the first transmission wall portion 60 and the operating plate portion 51, so that the connection portion is not easily damaged. As a result, the rigidity and strength of the operating member 50 can be improved, thereby fully suppressing the damage of the above-mentioned connection portion when the operating member 50 is operated. In the case where the second transmission wall portion 70 and the gap K are not present, the operation load F cannot be reliably dispersed, so the operation load F is easily concentrated on the connection portion between the base end of the first transmission wall portion 60 and the operating plate portion 51, resulting in damage.

[0140] In addition, in the case of the present embodiment, the base end portion 71 of the second transmission wall portion 70 is connected to both the first transmission wall portion 60 and the stop portion 63, so that the input portion (stop portion 63) of the operating load F when the operating member 50 is rotated can be close to the output portion of the operating load F (the load branch portion P for the operating load F to branch off).

[0141] Therefore, when the operation member 50 is rotated maximally relative to the base member 30 , the torque generated by the operation load F that can be received by the stopper 63 is reduced, thereby suppressing damage to the connection portion between the base end of the first transmission wall portion 60 and the operation plate portion 51 .

[0142] Moreover, in the locking device 10, a gap K is formed between the first transmission wall portion 60, the extension portion 73 of the second transmission wall portion 70 and the connecting portion and the operating plate portion 51, so that during the injection molding of the operating member 50, the shrinkage of the appearance surface (surface) of the operating plate portion 51 can be suppressed, thereby improving the aesthetics.

[0143] In addition, in this embodiment, if Figure 5 and Figure 6 As shown, a side wall portion 80 that connects the operation plate portion 51 and the first transmission wall portion 60 is provided on one side portion of the second transmission wall portion 70 in the width direction Y2.

[0144] According to the above configuration, the rigidity of the second transmission wall portion 70 can be increased. Therefore, when the operation load F is dispersed and transmitted to the second transmission wall portion 70 when the operation member 50 is rotated, damage to the second transmission wall portion 70 can be suppressed.

[0145] In addition, the side wall portion 80 is disposed on one side portion of the second transmission wall portion 70 in the width direction Y2. Therefore, when the operation member 50 is injection molded, for example, a mold M (see FIG. 1 ) that slides in a direction perpendicular to the surface of the side wall portion 80 can be used. Figure 5 ) for die cutting (refer to Figure 5 As shown in the arrow N), the manufacturability of the operating member 50 can be improved. If a wall portion is present in the center of the width direction of the second transmission wall portion 70, die cutting needs to be performed from both sides of the wall portion in a direction orthogonal to the surface of the wall portion, which increases the mold cost and makes it difficult to improve the manufacturability.

[0146] Furthermore, in this embodiment, if Fig. 9 As shown, the connecting portion is formed to be thinner than the extending portion 73 .

[0147] According to the above scheme, the connecting portion (here, the base end portion 54a of the partition wall portion 54 and the connecting ribs 83, 84) is formed in a manner that is thinner than the thickness of the extension portion 73. Therefore, during the injection molding of the operating member 50, it is not easy to shrink in the connecting portion (due to the small solidification shrinkage of the synthetic resin), thereby further improving the aesthetic appearance of the appearance of the operating plate portion 51.

[0148] In addition, in this embodiment, if Figure 3As shown in the partially enlarged perspective view of , when the surface area of ​​the second transmission wall portion 70 when viewed from the width direction Y2 is set to S1, and the surface area of ​​the second transmission wall portion 70 when viewed from the thickness direction is set to S2, S1<S2.

[0149] According to the above aspect, by adopting the above-mentioned structure, the second transmission wall portion 70 can be formed with a maximum width, thereby improving the rigidity of the second transmission wall portion 70. As a result, when the operation load F is dispersed and transmitted to the second transmission wall portion 70 when the operation member 50 is rotated, the second transmission wall portion 70 is not easily damaged.

[0150] Moreover, if Figure 3 to Figure 5 As shown, in the present embodiment, a partition wall portion 54 is erected from the back side of the operating panel portion 51 to separate the operating panel portion 51 and the operating portion 53, and the top end of the extension portion 73 (the top end of the second extension portion 76) is connected to the partition wall portion 54, and the partition wall portion 54 (the base end portion 54a of the partition wall portion 54) forms a connecting portion.

[0151] According to the above configuration, when the operation member 50 is rotated and the operation load F is transmitted to the second transmission wall portion 70 , the operation load F is transmitted to the operation plate portion 51 via the partition wall portion 54 , so that the operation load F can be more easily dispersed.

[0152] In addition, the partition wall portion 54 is a structure that prevents the operator's fingers from entering the inner side of the operating member 50, and is a member that is mostly erected and arranged on the back side of the operating plate portion 51. In the present embodiment, such a partition wall portion 54 is used as a part of the connecting portion, thereby reducing the volume of the connecting portion of the second transmission wall portion 70, and simplifying the shape and structure of the second transmission wall portion 70.

[0153] In addition, in this embodiment, if Figure 3 , Figure 5 as well as Fig. 9 As shown, connecting ribs 83 and 84 connecting the extension portion 73 and the operation plate portion 51 are provided at positions closer to the first transmission wall portion 60 than the connecting portion of the top end of the extension portion 73 with the partition wall portion 54 , and the connecting ribs 83 and 84 form a connecting portion.

[0154] According to the above aspect, by adopting the above-mentioned structure, the operation load F transmitted along the extension portion 73 of the second transmission wall portion 70 can be transmitted to the operation plate portion 51 via the connecting ribs 83 and 84 before reaching the partition wall portion 54, so that the operation load F can be more easily dispersed.

[0155] (Second embodiment of the locking device for the opening and closing body)

[0156] Figure 12 to Figure 14A 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.

[0157] like Fig.14 As shown, the locking device 10A of the opening and closing body of the second embodiment (hereinafter, simply referred to as the "locking device 10A") is different from the above-mentioned embodiment mainly in the shape of the first load transfer wall portion 60A (hereinafter, also simply referred to as the "first transfer wall portion 60A") provided on the operating member 50A.

[0158] That is, Fig.12 and Fig.13 As shown, the first transmission wall portion 60A of this embodiment is different from the substantially cylindrical first transmission wall portion 60 of the first embodiment and has a block shape extending along the extending direction X2 of the operation member 50A, and has a shape in which the key cylinder 69 cannot be inserted.

[0159] Furthermore, when the operating member 50 is rotated maximally relative to the base member 30, as shown in FIG. Fig.14 When the stopper 63 abuts against the stopper receiving portion 43, a portion of the operation load F borne by the stopper 63 is transmitted to the first transmission wall portion 60, and the remaining portion of the operation load F is transmitted to the second transmission wall portion 70. At this time, since the first transmission wall portion 60A has the shape as described above, Fig.14 As shown in the first path L1 , a part of the operation load F is transmitted obliquely inward toward the back side of the operation plate portion 51 and the other end side of the extending direction X2 .

[0160] That is, in this embodiment, the operating load F is dispersed in the first path L1 and the second path L2, so the operating load F is not easily concentrated on the connecting portion between the base end of the first transmission wall portion 60 and the operating plate portion 51, so that the connecting portion is not easily damaged, and the rigidity and strength of the operating member 50A can be improved, thereby fully suppressing the damage of the above-mentioned connecting portion when the operating member 50A is operated.

[0161] (Third Embodiment of the Locking Device for Opening and Closing Body)

[0162] Figure 15 to Figure 17 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 the same reference numerals are given to substantially the same parts as those in the above embodiment, and description thereof is omitted.

[0163] like Fig.16As shown, the locking device 10B of the opening and closing body of the third embodiment (hereinafter, simply referred to as the "locking device 10B") is different from the above-mentioned embodiment mainly in the shape of the base member 30B and the shape of the second load transfer wall portion 70B (hereinafter, also simply referred to as the "second transfer wall portion 70B") constituting the operating member 50B.

[0164] That is, Fig.15 As shown, the base end portion 71 of the second transmission wall portion 70B of the present embodiment is connected to a position separated from the stopper portion 63 provided in connection with the first transmission wall portion 60 .

[0165] Furthermore, the leading end side of the first extension portion 75 extending obliquely from the base end portion 71 in the extension direction is connected to the operation plate portion 51 via the connection rib 83. Furthermore, the second extension portion 76B extending in the form of a protrusion from one side portion in the width direction Y2 of the connection rib 83 and connected to the back surface of the operation plate portion 51. Furthermore, the leading end 77 in the extension direction of the second extension portion 76B is connected to the damper contact portion 67B in the form of a substantially Y-shaped rib connected to the back surface of the operation plate portion 51.

[0166] That is, in the present embodiment, the connecting rib 83, the second extending portion 76B, and the damper contact portion 67B form the “connecting portion” of the present invention.

[0167] In addition, if Fig.16 As shown, the base member 30B is rotatably attached to a rotating member 25B on its back side (rear side) via a support shaft 26. It should be noted that a torsion spring 28 is attached to the rotating member 25B, and the top ends 22, 22 of the pair of locking members 20, 20 attached to the rotating member 25B are rotated and urged in a direction to engage with the pair of locking parts 3, 3.

[0168] Furthermore, when the operating member 50 is rotated maximally relative to the base member 30, as shown in FIG. Fig.17 When the stopper 63 abuts against the stopper receiving portion 43, the operation load F borne by the stopper 63 is first transmitted to the first transmission wall portion 60. Thereafter, the operation load F transmitted along the first transmission wall portion 60 is branched from the load branching portion P and is dispersed to the first path L1 along the first transmission wall portion 60 and the second path L2 along the second transmission wall portion 70.

[0169] Then, the operation load F transmitted through the first path L1 is transmitted to the operation plate portion 51 .

[0170] On the other hand, a part of the operation load F transmitted in the second path L2 passes through the first extension portion 75 and is transmitted to the operation plate portion 51 via the connecting rib 83. Furthermore, the remaining part of the operation load F passes through the second extension portion 76B and is transmitted to the operation plate portion 51 via the second extension portion 76B, and after passing through the second extension portion 76B, is transmitted to the operation plate portion 51 via the damper contact portion 67B.

[0171] Furthermore, in the present embodiment, the operation load F can be dispersed not only by the second transmission wall portion 70 but also by the damper contact portion 67B with which the damper 45 contacts, so that the shape and structure of the operation member 50B can be simplified.
