JP 2004-156331 A

  By the way, in the fastening structure of the locking device 73, when the locking device 73 is assembled, when the screw member 81 is tightened, a rotational torque in the clockwise direction in FIG. On the other hand, in the fastening structure described above, the positioning pin 79 is inserted into the positioning hole 78 to perform positioning in the width direction and the height direction, and then the screw member 81 is tightened. 79 may be bent, and the lock device 73 may be assembled out of the normal position in the recess 72. Accordingly, the operation handle 74 is displaced from the normal position in the recess 72, that is, assembled in an inclined state, and the gap between the operation handle 74 and the inner wall surface of the recess 72 becomes non-uniform, and the appearance may be deteriorated. .

  The present invention has been made in view of such a situation, and the object thereof is to suppress the displacement of the lock device accompanying the tightening of the screw member, and to suppress the deterioration of the appearance due to the displacement. An object of the present invention is to provide a fastening structure for a locking device.

In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that a storage device provided on the support body so as to be openable and closable and having a concave portion on an outer wall, a part of which is disposed in the concave portion, A locking device that locks the locking device in a closed position and releases the locking in response to an operation of an operating member, and the locking device is positioned at a predetermined position in the recess by a positioning pin, and the locking device is The locking structure of the locking device is configured to be fastened to the mounting wall by a screw member, provided with a rotation restricting portion that restricts the rotation of the locking device accompanying the fastening by the screw member , A projecting portion which is a mounting wall and is provided at a plurality of locations in front of the locking device in the rotational direction and contacts or corresponds to the locking device positioned by the positioning pin. It is the gist of.

  According to said structure, when assembling | attaching the locking device to the storage tool, a part of the locking device is arrange | positioned in a recessed part. The locking device is positioned at a predetermined (normal) position in the recess by the positioning pin, and in this state, the locking device is fastened to the mounting wall of the recess by the screw member. At this time, rotational torque acts on the locking device as the screw member is tightened, and the locking device is rotated with respect to the mounting wall while bending the positioning pin. In this regard, in the first aspect of the invention, the rotation restricting portion receives at least a part of the rotation torque, and accordingly, the rotation torque acting on the positioning pin is reduced accordingly. As a result, the degree of bending of the positioning pin is reduced compared to the case where the rotational torque is received only by the positioning pin, and a phenomenon in which the lock device is assembled with a deviation from the normal position in the recess defined by the positioning pin is unlikely to occur. As a result, the gap between the operating member and the inner wall surface of the recess becomes non-uniform due to the positional deviation, and the phenomenon that the appearance is deteriorated hardly occurs.

Further , in a state where the lock device is disposed in the recess and is positioned by the positioning pin, the rotation restricting portion including the protrusion is in contact with or equivalent to the lock device. The rotation restricting portion is an attachment wall of the recess and is located in front of the locking device in the rotation direction. Therefore, when rotational torque acts on the locking device as the screw member is tightened, the locking device tries to rotate with respect to the mounting wall while bending the positioning pin, but a part of the rotational torque is received by the rotation restricting portion. . Correspondingly, smaller rotational torque acting on the positioning pin, the upper climate fruit can be surely obtained.

Furthermore , when rotational torque acts on the locking device as the screw member is tightened, the rotational torque is received by the rotation restricting portions provided at a plurality of locations on the mounting wall of the recess. The rotational torque received by the rotation restricting portion per place is reduced, and each rotation restricting portion can be configured to be small.

Note that, as the locking device, for example, according to the invention described in claim 2 , the storage tool is locked in a closed position by engaging a slide pin with a lock hole formed in the support body, and the operation is performed. A member that releases the lock when the slide pin is retracted from the lock hole by operating a member can be used.

Further, as the storage device, as in the invention described in claim 3 , there is a grab box that uses an instrument panel of a vehicle as a support and is attached to the instrument panel so as to be openable and closable.

  According to the fastening structure of the locking device according to the present invention, it is possible to suppress the displacement of the locking device that accompanies the tightening of the screw member, and it is possible to suppress a decrease in appearance due to the displacement.

  Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS. In the description of the positional relationship, when the front-rear relationship is indicated, it is used according to the front-rear direction of the vehicle.

  As shown in at least one of FIGS. 1 to 3, in the instrument panel 11 of the vehicle, a recess 12 that opens at the rear end surface is provided at a position corresponding to the front of the passenger seat. 12, a grab box 13 is provided to be openable and closable. Here, the instrument panel 11 corresponds to a support in claims, and the grab box 13 corresponds to a storage device.

  The grab box 13 includes a box body 14 having a bottomed box shape with an open upper end, and a cover portion 15 attached to the box body 14 from the rear side. The box body 14 is for accommodating small items and occupies most of the grab box 13. The cover portion 15 is a member that constitutes the outer wall of the grab box 13, and the rear surface 15A serves as a design surface. The cover portion 15 is supported at the lower end portion thereof by the shaft 16 so as to be pivotable in the vertical direction on the inner wall 17 of the recess 12. The box main body 14 and the cover portion 15 are located between an “open position” that falls from the recess 12 toward the passenger seat and a “closed position” that is stored in the recess 12 (see FIGS. 1 to 3). Rotate.

  In the upper part of the cover part 15, there is provided a concave part 18 that opens in a substantially rectangular shape on the rear face 15 </ b> A and is recessed forward. The concave portion 18 has a bottomed box shape with an upper end opened. Here, in order to specify each part of the recess 18, a part that is separated from the opening 21 of the cover part 15 by a predetermined distance forward is referred to as an “attachment wall 19”, and both side edges 21 </ b> B (see FIG. 10) of the opening 21 and the above attachments. A location connecting both side edges of the wall 19 is referred to as a “side wall 22”, and a location connecting the lower edge of the opening 21 and the lower edge of the mounting wall 19 is referred to as a “bottom wall 23”. At least the upper part of the rear surface of the mounting wall 19 is formed as a flat surface. A notch 24 is formed at the top of each side wall 22, and the upper end of the side wall 22 is lower than the mounting wall 19.

  A lock device 26 is provided between the box body 14 and the cover portion 15 to lock the grab box 13 in the closed position and to release the lock according to the operation of the operation member.

  As shown in at least one of FIGS. 4 to 6, the locking device 26 includes a support frame 27, an operation handle 25 as the operation member, a pair of left and right slide pins 28, a pair of left and right cam members 29, and a pair of left and right cams. A spring 31 is provided.

  The support frame 27 is disposed in the recess 18 and fastened to the upper portion of the mounting wall 19 by a fastening structure described later (see FIG. 3). A pair of left and right support pieces 33 projecting rearward and having rectangular support holes 32 (see FIG. 7) are formed on the left and right side edges of the support frame 27. In addition, flat ribs that protrude forward are formed at a plurality of locations on the support frame 27. These ribs are composed of four pieces of vertical ribs 34 to 37 extending in a substantially vertical direction and two pieces of horizontal ribs 38 and 39 extending in a substantially horizontal direction. The upper part of each of the vertical ribs 34 to 37 and above the horizontal rib 38 is inclined so as to become lower toward the front side. Cylindrical bosses 41 and 42 projecting forward are formed at the left and right ends of the support frame 27, respectively. The boss 41 is located between the adjacent vertical ribs 34 and 35, and the boss 42 is located between the adjacent vertical ribs 36 and 37. The front end surfaces of the vertical ribs 34 to 37, the horizontal ribs 38 and 39, and the bosses 41 and 42 are located on the same plane.

  The operation handle 25 includes an operation portion 43 having a horizontally long, substantially rectangular plate shape, and a pair of left and right guide portions 44 integrally formed in a cylindrical shape on the upper front side of the operation portion 43. Each guide portion 44 extends in the left-right direction and is open at both ends. The operation handle 25 is disposed above the opening 21 in the recess 18 and can swing in the vertical direction with the guide portions 44 disposed between the left and right support pieces 33 as fulcrums (see FIG. 3).

  The left and right cam members 29 are for converting the swinging motion of the operation handle 25 into a reciprocating linear motion in the left-right direction. Each cam member 29 has a rectangular tube portion 45 and a cylindrical portion 46 arranged in parallel in the left-right direction. The cam member 29 is accommodated in the guide portion 44 in the cylindrical portion 46, and corresponds to the rectangular tube portion 45. The support piece 33 is inserted through the support hole 32 (see FIG. 7). Since the square cylindrical portion 45 and the support hole 32 have a rectangular cross section, each cam member 29 can be moved in the left-right direction, but cannot be rotated around its axis. A cam groove 47 is formed on the outer periphery of each cam member 29, and a protrusion 48 provided in the guide portion 44 is engaged with the cam groove 47. As the operation handle 25 swings, the engagement position of the projection 48 in the cam groove 47 changes, and the cam member 29 reciprocates linearly in the left-right direction so that it protrudes and retracts from the guide portion 44. This intrusion is performed in the notch 24 of each side wall 22.

  Each of the left and right slide pins 28 is connected to a corresponding cam member 29 at one end thereof, and moves in the left-right direction as the cam member 29 reciprocates linearly according to the swing operation of the operation handle 25.

  Each of the left and right springs 31 is disposed in a compressed state in each guide portion 44 of the operation handle 25 and biases the left and right cam members 29 in a direction in which the left and right cam members 29 protrude from the guide portion 44. This urging direction is a direction in which the left and right slide pins 28 are engaged with lock holes 49 formed in the inner wall 17 of the recess 12.

  In the lock device 26 configured as described above, when the occupant does not operate the operation handle 25, as shown in FIG. 5A, each cam member 29 urged by the spring 31 projects greatly from the guide portion 44, and together with this, The end of the slide pin 28 engages in the corresponding lock hole 49, and the grab box 13 is locked in the closed position. At this time, the operation handle 25 is in a substantially vertical state. When the occupant pulls the operating handle 25 forward and swings upward from this state, the cam members 29 are inserted into the guide portions 44 against the springs 31 as shown in FIG. At the same time, each slide pin 28 moves backward and comes out of the lock hole 49. The lock device 26 is unlocked, and the grab box 13 can be rotated toward the open position.

In addition, 50 in FIG.4 and FIG.5 is a hole for attaching a locking mechanism (not shown).
Next, the fastening structure with respect to the attachment wall 19 of the said support frame 27 is demonstrated. As shown in at least one of FIGS. 6 and 7, a boss 52 having a screw hole 51 into which a screw member 57 such as a screw can be screwed on the front surface of the support frame 27, and a screw that can be screwed into the screw member 58. A boss 54 having a hole 53 is formed. The boss 52 is located between the vertical ribs 34 and 35 and directly below the boss 41. This position is where the transverse rib 39 intersects. Similarly, the boss 54 is located between the vertical ribs 36 and 37 and directly below the boss 42. This position is where the transverse rib 39 intersects. The front end surfaces of the left and right bosses 52 and 54 are located on the same plane as the front end surfaces of the bosses 41 and 42, the vertical ribs 34 to 37, and the horizontal ribs 38 and 39 described above.

  A hole 55 into which the screw member 57 can be inserted is formed at a position corresponding to the screw hole 51 of the boss 52 in the upper part of the mounting wall 19. Further, a hole 56 through which the screw member 58 can be inserted is formed at a position corresponding to the screw hole 53 of the boss 54.

  Further, in order to position the support frame 27 with respect to the mounting wall 19 in the width direction and the height direction, positioning pins 61 and 62 are formed on the front surface of the support frame 27 and in the vicinity of the screw holes 51 and 53, respectively. Has been. The positioning pin 61 is formed integrally with the vertical rib 35, and the positioning pin 62 is formed integrally with the vertical rib 36. Both positioning pins 61 and 62 protrude forward from both vertical ribs 35 and 36.

  In the upper part of the mounting wall 19, positioning holes 63 and 64 are formed at two locations corresponding to the positioning pins 61 and 62. In consideration of tolerances of the positioning pins 61 and 62, one positioning hole 63 is formed in a horizontally long shape so that the positioning pins 61 and 62 can be surely inserted into the corresponding positioning holes 63 and 64.

  When the lock device 26 is assembled to the grab box 13, at least a part of the lock device 26 (the support frame 27, the operation handle 25, both cam members 29, both springs 31, etc.) is disposed in the recess 18. The The positioning pin 61 is inserted into the positioning hole 63 and the positioning pin 62 is inserted into the positioning hole 64, whereby the support frame 27 and the like of the lock device 26 are positioned at a predetermined (normal) location in the recess 18. The screw holes 51 and 53 match the corresponding holes 55 and 56. As shown in FIG. 10, the upper surface 25A of the operation handle 25 is substantially horizontal, and the left and right side surfaces 25B are substantially vertical. The gap between the upper surface 25A of the operation handle 25 and the upper edge 21A of the opening 21 is uniform, and the gap between the left and right side surfaces 25B of the operation handle 25 and the corresponding side edge 21B of the opening 21 is uniform.

  In this state, the screw member 57 is screwed into the screw hole 51 through the hole 55, and the screw member 58 is screwed into the screw hole 53 through the hole 56. As shown in FIGS. Fastened to the mounting wall 19 of the recess 18.

  By the way, according to the above-described fastening structure, when the screw members 57 and 58 are tightened, the rotational torque in the clockwise direction acts on the support frame 27, but the positioning pins 61 and 62 may be thin (diameter is about 3 mm). The positioning pins 61 and 62 may be bent in the same direction, and the support frame 27 may be assembled out of the normal position in the recess 18. Accordingly, the operation handle 25 is assembled in a state of being shifted from the normal position in the recess 18, that is, tilted. The gap between the upper surface 25A of the operation handle 25 and the upper edge 21A of the opening 21 is not uniform in the left-right direction, as indicated by the two-dot chain line in FIG. Similarly, the gap between the left and right side surfaces 25B of the operation handle 25 and the corresponding side edge 21B of the opening 21 is also non-uniform in the height direction as shown by the two-dot chain line in FIG. Such unevenness of the gap contributes to a decrease in the appearance of the operation handle 25 and its peripheral portion.

  Therefore, in this embodiment, a rotation restricting portion that restricts the rotation of the lock device 26 accompanying the fastening by the screw members 57 and 58 is provided. As shown in FIGS. 6 and 7, the rotation restricting portion is constituted by protrusions 65 and 66 provided at a plurality of locations on the mounting wall 19 of the recess 18. One protrusion 65 is provided above the boss 41 and the positioning pin 61 and at a portion corresponding to the inclined portion of the vertical rib 35 and the horizontal rib 38, and has an elongated shape in the left-right direction. This location corresponds to the front in the rotational direction of the positioning pin 61 by the rotational torque. The other protrusion 66 is provided below the positioning pin 62 and at a location corresponding to the lower surface of the lateral rib 39. This location corresponds to the front of the positioning pin 62 in the rotational direction due to the rotational torque.

  In the present embodiment configured as described above, when the screw members 57 and 58 are tightened when the locking device 26 is assembled to the grab box 13, a rotational torque in the clockwise direction acts on the locking device 26 along with the tightening. To do. While the positioning pins 61 and 62 are bent, the locking device 26 is rotated with respect to the mounting wall 19.

  However, as shown in FIGS. 8 and 9, the protrusions 65, 66 are provided on the mounting wall 19 of the recess 18 and in front of the locking device 26 in the rotational direction, and are positioned by the positioning pins 61, 62. In the state before the fastening by the screw members 57 and 58, the projections 65 and 66 are in contact with or equivalent to the support frame 27 of the lock device 26. Here, the “corresponding state” refers to a state in which the protrusions 65 and 66 are close to the support frame 27 and come into contact with the support frame 27 when the locking device 26 rotates even slightly.

  These protrusions 65 and 66 contact the support frame 27 to receive at least a part of the rotational torque. Therefore, the rotational torque acting on the positioning pins 61 and 62 is reduced by the amount received. In particular, in this embodiment, since the protrusions 65 and 66 are provided at two different locations on the mounting wall 19, the rotational torque is received by these protrusions 65 and 66. The rotational torque received by one protrusion 65, 66 is reduced.

  As a result, compared to the case where the rotational torque is received only by the positioning pins 61 and 62 (the background art corresponds to this), the degree of bending of the positioning pins 61 and 62 is reduced, and the locking device 26 is moved to the positioning pins 61 and 62. The phenomenon that the assembly is shifted from the regular position in the recess 18 defined by the above is unlikely to occur. Along with this, the phenomenon that the operation handle 25 arranged at a regular place before the fastening is inclined after the fastening (see the two-dot chain line in FIG. 10) is less likely to occur. Even after the fastening, the operation handle 25 is held in a state (see a solid line in FIG. 10) arranged at a normal position.

According to the embodiment described in detail above, the following effects can be obtained.
(1) The locking device 26 is fastened to the mounting wall 19 of the recess 18 by the screw members 57 and 58 in a state where a part of the locking device 26 is positioned at a predetermined position in the recess 18 by the positioning pins 61 and 62. In the fastening structure of the locking device 26 thus configured, a rotation restricting portion that restricts the rotation of the locking device 26 accompanying the fastening by the screw members 57 and 58 is provided. Therefore, it is possible to suppress the position shift of the lock device 26 accompanying the tightening of the screw members 57 and 58, and to suppress the phenomenon that the appearance of the operation handle 25 is inclined to be lowered.

  (2) The rotation restricting portion is provided on the mounting wall 19 of the recess 18 and in front of the locking device 26 in the rotation direction, and is in contact with or equivalent to the locking device 26 positioned by the positioning pins 61 and 62. It is comprised by the parts 65 and 66. Therefore, the rotational torque accompanying the tightening of the screw members 57 and 58 can be received by the protrusions 65 and 66, and the effect (1) can be ensured.

  (3) Protrusions 65 and 66 are provided at two different locations on the mounting wall 19. Therefore, the rotational torque received by one protrusion 65, 66 can be reduced, and each protrusion 65, 66 can be configured to be small.

  (4) In order to solve the problem of suppressing the displacement of the locking device 26 accompanying the tightening of the screw members 57 and 58, it is only necessary to provide the protrusions 65 and 66 on the concave portion 18 side (mounting wall 19). It is not necessary to take measures for members on the device 26 side (such as the support frame 27).

Note that the present invention can be embodied in another embodiment described below.
