Description

[Technical field]

[0001] The present invention relates to an improved technique for a locking device capable of locking a second member, which is rotatably supported by a first member, to the first member. [Background technology]

[0002] For example, a storage device such as a glove box for a vehicle includes a storage body (first member) having an opening, and a lid (second member) supported rotatably in a direction to open and close the opening relative to the storage body. A locking device for this storage device locks the lid in a closed state relative to the storage body, and can release the locked state by operating an operating handle. A conventional technique for such a locking device is disclosed in, for example, Patent Document 1 (see Figs. 2 and 5).

[0003] The locking device disclosed in Patent Document 1 includes a leaf spring that biases the lid in an opening direction relative to the striker when the lid latch is engaged with the striker of the storage body, thereby preventing the lid from rattling when closed.

[0004] The leaf spring is attached as follows: A lock body is fixed to the underside of the lid. An upright positioning pin is provided on the underside of this lock body. Furthermore, an engagement hole is formed in an upright piece that stands from part of the edge of the lock body to the underside, penetrating in a direction along the underside of the lock body. The base end of the leaf spring is placed over the underside of the lock body. An engagement protrusion (engagement claw) is formed on the edge of this base end for engaging with the engagement hole. Furthermore, the base end has an engagement hole into which the pin fits.

[0005] To attach the base end of the leaf spring to the lock body of the lid, first insert (hook) the engaging protrusion of the base end into the engaging hole of the lock body. Next, align the pin by fitting it into the engaging hole, and then place the base end of the leaf spring on the back surface of the lock body. As a result, the base end of the leaf spring is provisionally assembled to the lock body. In this provisionally assembled state, the engaging protrusion is engaged with the engaging hole, so the free end of the leaf spring will not fall downward under its own weight. Finally, the base end is completely fixed to the lock body with a bolt. [Prior art documents] [Patent documents]

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. Note that the embodiments shown in the accompanying drawings are merely examples of the present invention, and the present invention is not limited to these embodiments.

[0017] <Example> A locking device 10 according to an embodiment will be described with reference to FIGS.

[0018] 1A shows a storage device 20 equipped with a locking device 10. The storage device 20 is used, for example, as a glove box for a vehicle. The storage device 20 includes a resin storage body 30 (first member 30) having an opening 31, and a resin lid 40 (second member 40) supported on the storage body 30 so as to be rotatable in a direction for opening and closing the opening 31.

[0019] The locking device 10 is configured to be able to lock the lid 40 to the storage body 20. As shown in Fig. 1B, the locking device 10 can change the lid 40 from a fully closed state to an open state as shown in Fig. 1A by operating the operating member 50 to open (swing in the direction of arrow R1).

[0020] In the description, front, rear, left, right, top, and bottom refer to the left, front, rear, right, top, and bottom, respectively, when the storage device 20 is viewed from the opening / closing direction of the lid 40. In the drawings, Fr indicates front, Rr indicates rear, Le indicates left, Ri indicates right, Up indicates top, and Dn indicates bottom.

[0021] 2, the lid 40 has supported portions 42, 42 on the left and right sides of a lower end portion 41a of the back surface 41, which are rotatably supported by a support shaft (not shown) on the storage body 30. Furthermore, at an upper end portion 43 of the lid 40, as shown in Figs. 1A and 2, an operation opening 44 for arranging an operation member 50 and an operation recess 45 recessed from the operation opening 44 toward the back surface 41 of the lid 40 are formed. The operation recess 45 is formed by a bulging portion 46 that bulges from the lid 40 toward the back surface 41.

[0022] As shown in Figs. 2 to 5, the operating member 50 (operating handle 50) is a resin molded product and is located in the operating opening 44 of the lid 40. The operating member 50 is supported by a horizontal support shaft 51 so as to be rotatable (swingable) on the lid 40. Stoppers 53, 53 are integrally provided on a back surface 52 of the operating member 50. That is, the stoppers 53, 53 are resin molded products formed integrally with the operating member 50. When the stoppers 53, 53 abut against the back surface 41 of the lid 40, a surface 54 of the operating member 50 in the closed state is positioned flush with the surface 47 of the lid 40 (see Fig. 5). Furthermore, the operating member 50 is biased toward the closing side by a return spring 61. The return spring 61 is, for example, formed of a torsion coil spring.

[0023] 1B, by hooking a hand on the lower edge of the operating member 50 and pulling it toward oneself, the operating member 50 rotates counterclockwise (in the direction of arrow R1 in FIG. 1B) against the biasing force of the return spring 61. Thereafter, when the hand is released from the operating member 50, the operating member 50 automatically returns to its original closed position by the biasing force of the return spring 61.

[0024] As shown in Figures 3 to 5, the locking device 10 includes a latch 70 provided on the operating member 50, a striker 80 provided on the storage body 30 (see Figure 1A) so as to be engageable with the latch 70, and a leaf spring 90 attached to the lid 40 so as to bias the striker 80.

[0025] The striker 80 is a generally U-shaped member extending from the storage main body 30 toward the back surface 41 of the lid 40. In detail, the striker 80 is composed of a pair of arms 81, 81 extending from the storage main body 30 toward the back surface 41 of the lid, and a striker main body 82 connecting the tips of the arms 81, 81. The striker main body 82 is a bar parallel to the back surface 52 of the operating member 50 in the closed state.

[0026] The latch 70 has an inverted L-shape extending from one end (upper end) of the back surface 52 of the operating member 50 toward the striker 80. The latch 70 is composed of a leg 71 extending from the back surface 52 of the operating member 50 along the striker 80, and a latch claw 72 extending from the tip of the leg 71 so as to be able to be latched to the striker main body 82. The latch 70 is a resin molded product formed integrally with the operating member 50.

[0027] When the operating member 50 is in a closed state relative to the lid 40, the latch claw portion 72 of the latch 70 is in a state of abutment with the striker body 82, that is, in a latched engaged state (locked state). Thereafter, by rotating the operating member 50, the latch claw portion 72 rotates together with the operating member 50 and moves away from the striker body 82 to be disengaged (unlocked).

[0028] As shown in FIG. 5, when the latch 70 is engaged with the striker 80 (in a locked state), the leaf spring 90 comes into contact with the striker 80, thereby biasing the lid 40 in an opening direction R2 (the direction of the arrow R2) relative to the striker 80.

[0029] 6, this leaf spring 90 has a base end 91 attached to a spring mounting portion 100 of the lid 40, and a tip end serving as a free end 93. The base end 91 has a mounting hole 91a that passes through and can be attached to the spring mounting portion 100, and a positioning hole 91b and a positioning recess 91c that pass through the mounting hole 91a along the center line CL of the mounting hole 91a.

[0030] As shown in Figs. 3 to 6, the lid 40 includes a resin spring mounting portion 100 integrally formed on the back surface 41. The spring mounting portion 100 is located on one side of the operation opening 44 in the axial direction of the support shaft 51. A spring mounting surface 101 of the spring mounting portion 100 is a flat surface on which the plate surface of the base end portion 91 of the leaf spring 90 can be overlapped and attached, and is parallel to the back surface 41 of the lid 40. Furthermore, as shown in Fig. 5, when the lid 40 is in the closed state, the spring mounting surface 101 is located closer to the back surface 41 of the lid 40 than the striker body 82.

[0031] 4 and 6, the spring mounting part 100 includes a positioning pin 102 that can be fitted into a positioning hole 91b of the base end 91 of the leaf spring 90, and a positioning protrusion 103 that can be fitted into a positioning recess 91c of the base end 91. The positioning pin 102 and the positioning protrusion 103 extend from the spring mounting part 100 toward the base end 91 of the leaf spring 90. The position of the leaf spring 90 relative to the lid 40 can be accurately adjusted by overlapping the base end 91 of the leaf spring 90 on the spring mounting surface 101, fitting the positioning hole 91b of the base end 91 into the positioning pin 102, and fitting the positioning recess 91c of the base end 91 into the positioning protrusion 103.

[0032] Furthermore, the base end 91 of the leaf spring 90 is fixed to the spring mounting part 100 by a fixing means 110. This fixing means 110 is constituted by a screw member 111 such as a screw or a tapping screw that is inserted through a mounting hole 91a of the leaf spring 90. The base end 91 of the leaf spring 90 can be attached to the spring mounting part 100 by screwing the screw member 111 that is inserted through the mounting hole 91a into a screw hole 104 provided in the spring mounting part 100. It should be noted that the fixing means 110 is not limited to the screw member 111, and may be, for example, a rivet or a heat caulking.

[0033] The leaf spring 90 will be described in more detail. As shown in Figures 5 and 6, the leaf spring 90 is composed of the above-mentioned horizontal base end portion 91 attached to the spring attachment portion 100, an elastic portion 92 extending obliquely upward from an end 91d of the base end portion 91 toward the striker body 82 (the side opposite the back surface 41 of the lid 40), and a contact portion 93 (free end 93) at the tip of the elastic portion 92.

[0034] As shown in FIG. 5, when the latch 70 is engaged with the striker 80 (in a locked state), the contact portion 93 of the leaf spring 90 presses the striker body 82 toward the latch claw portion 72 of the latch by the biasing force of the elastic portion 92.

[0035] As shown in Fig. 7, it is preferable to assemble the leaf spring 90 with the spring mounting surface 101 facing upward. In this case, in a provisionally assembled state in which the base end 91 overlaps with the spring mounting surface 101 facing upward, the free end 93 side of the leaf spring 90 tends to fall toward the lid 40 due to its own weight. In other words, as shown in Fig. 8, the leaf spring 90 falls toward the free end 93 side with the position of the end 91d of the base end 91 (the boundary 91d between the base end 91 and the elastic portion 92) as the fulcrum Su.

[0036] 7, in this embodiment, the operating member 50 is provided with a spring holding portion 120 capable of temporarily holding the free end 93 side of the leaf spring 90 in a state where it is assembled to the lid 40. This spring holding portion 120 faces the leaf spring 90 so as to be able to hold the weight of the free end 93 side of the leaf spring 90 in a temporarily assembled state where the base end 91 of the leaf spring 90 overlaps (is placed on) the spring mounting surface 101 in an upward state.

[0037] The spring holding portion 120 is constituted by a reinforcing rib 121 formed on the operating member 50. For example, as shown in Fig. 3, the reinforcing rib 121 is constituted by a vertical plate-like member that connects (is integrally molded with) the operating member 50, the stopper 53, and the leg portion 71 of the latch 70. The reinforcing rib 121 can also serve as the spring holding portion 120. The use, type, shape, and size of the reinforcing rib 121 are arbitrary.

[0038] 7 and 8, when the spring mounting surface 101 faces upward, the tip 122 of the spring holding portion 120 facing the leaf spring 90 is positioned at the same height or higher than the position of the spring mounting surface 101. For example, the tip 122 of the spring holding portion 120 is positioned higher than the spring mounting surface 101. The inclination angle of the elastic portion 92 with respect to the spring mounting surface 101 is θ. The magnitude of this inclination angle θ is arbitrary, and is set to an appropriate magnitude such that the tip 122 of the spring holding portion 120 does not interfere with the operation of the leaf spring 90 when the leaf spring 90 is completely attached to the spring mounting surface 101 as shown in FIG.

[0039] 7 and 8, the length L1 of the positioning pin 102 relative to the spring attachment surface 101 is longer than the length L2 of the positioning pin 102 fitted into the positioning hole 91b in a state in which the free end 93 side of the leaf spring 90 is held by the spring holding portion 120. Therefore, the positioning pin 102 fits into the positioning hole 91b.

[0040] As shown in FIG. 5, when the base end 91 of the leaf spring 90 is completely attached to the spring attachment surface 101 , the free end 93 side of the leaf spring 90 is separated from the spring holding portion 120 .

[0041] 5, in a state in which the striker 80 is engaged with the latch 70, the free end 93 of the leaf spring 90 urges the striker body 82 of the striker 80 toward the latch claw portion 72 of the latch 70. As a result, a reaction force acts on the leaf spring 90. The leaf spring 90 urges the striker 80 in the opening direction R2 (the direction of the arrow R2) of the lid 40, with the free end 93 abutting against the striker body 82 as a fulcrum.

[0042] Next, a procedure for assembling the leaf spring 90 to the lid 40 will be described with reference to FIGS.

[0043] First, as shown in FIG. 7, the operating member 50 is attached to the lid 40. Next, the lid 40 is placed on the horizontal assembly stand 200 (mounting stand 200) with the surface 47 of the lid 40 facing downward. In this state, the surface 54 of the operation member 50 in the closed state is located flush with the surface 47 of the lid 40.

[0044] Next, the base end 91 of the leaf spring 90 is placed on top of the spring mounting surface 101 facing upward. At this time, as shown in Fig. 6, the positioning hole 91b of the base end 91 is fitted into the positioning pin 102, and the positioning recess 91c of the base end 91 is fitted into the positioning protrusion 103, thereby aligning the position of the leaf spring 90 with respect to the lid 40. When the base end 91 of the leaf spring 90 is placed on the spring mounting surface 101 from above, the free end 93 of the leaf spring 90 drops due to its own weight, but is held by the tip 122 of the spring holding portion 120. Therefore, the inclination of the leaf spring 90 can be maintained in a stable provisionally assembled state with respect to the spring mounting surface 101.

[0045] Next, the base end 91 is completely fixed to the spring attachment portion 100 by the fixing means 110. As a result, the free end 93 side of the leaf spring 90 moves away from the spring holding portion 120. This completes the assembly of the leaf spring 90 to the lid 40.

[0046] The above description of the embodiment can be summarized as follows.

[0047] 1 to 8, the locking device 10 is configured to be capable of locking a lid 40 (second member 40) supported rotatably in a direction for opening and closing the opening 31 to a storage main body 20 (first member 30) having an opening 31. The locking device 10 includes an operation member 50 rotatably supported on the lid 40, a latch 70 provided on the operation member 50, a striker 80 provided on the storage main body 20 to be engageable with the latch 70, and a leaf spring 90 that biases the lid 40 in an opening direction R2 (arrow R2 direction) relative to the striker 80 when the latch 70 is engaged with the striker 80.

[0048] The leaf spring 90 has a base end 91 that can be assembled to the lid 40, and a tip end 93 that is a free end that can abut against the striker 80. The base end 91 has a positioning hole 91b that penetrates in the plate surface direction of the leaf spring 90. The lid 40 has a spring mounting surface 101 on which the base end 91 can be overlapped, and a positioning pin 102 that can be fitted into the positioning hole 91b of the base end 91 overlapping the spring mounting surface 101. The operating member 50 has a spring holding portion 120 that can temporarily hold the free end 93 (tip end 93) side of the leaf spring 90 when assembled to the lid 40. The spring holding portion 120 faces the leaf spring 90 so as to be able to hold the weight of the free end 93 side of the leaf spring 90 in a temporary assembly state in which the base end 91 overlaps the spring mounting surface 101 in an upward state.

[0049] 7 and 8, when the leaf spring 90 is assembled to the spring mounting portion 100 of the lid 40, the spring mounting surface 101 of the spring mounting portion 100 is placed in an upward position. In the case of a temporary assembly state in which the base end 91 of the leaf spring 90 is placed on top of the spring mounting surface 101 in the upward position, the positioning hole 91b of the base end 91 is aligned with the positioning pin 102 and fitted in.

[0050] However, in the case of a temporary assembly in which the base end 91 of the leaf spring 90 is placed on top of the spring mounting surface 101 facing upward, the free end 93 of the leaf spring 90 tends to fall downward due to its own weight.

[0051] In response to this, by temporarily holding the free end 93 side of the leaf spring 90 by the spring holding portion 120, it is possible to prevent the free end 93 side from falling. Therefore, the temporarily assembled state of the base end 91 of the leaf spring 90 with respect to the spring mounting surface 101 can be stably maintained. As a result, it is possible to prevent the leaf spring 90 from falling off the spring mounting surface 101. Since the positioning hole 91b does not come off the positioning pin 102, the position of the leaf spring 90 with respect to the spring mounting surface 101 can be reliably maintained.

[0052] In this manner, the leaf spring 90 can be easily and reliably maintained in a provisionally assembled state on the spring mounting surface 101 by a single process of simply stacking the base end 91 of the leaf spring 90 on the spring mounting surface 101 facing upward and fitting the positioning hole 91b of the base end 91 onto the positioning pin 102. Thereafter, the base end 91 of the leaf spring 90 can be completely attached to the spring mounting surface 101 by the fixing means 110. As a result, the efficiency of the assembly work of the locking device 10 and the number of assembly steps can be improved.

[0053] 7, when the spring mounting surface 101 faces upward, the tip 122 of the spring holding portion 120 facing the leaf spring 90 is located at least at the same height as the position of the spring mounting surface 101. When the tip 122 of the spring holding portion 120 holds the weight of the free end 93 side of the leaf spring 90, the positioning hole 91b fits into the positioning pin 102.

[0054] In this way, since the tip 122 of the spring holding portion 120 is at least the same height as the spring mounting surface 101, it is possible to minimize the inclination of the free end 93 side of the leaf spring 90. Therefore, it is possible to minimize the inclination of the base end 91 of the leaf spring 90 with respect to the spring mounting surface 101. Accordingly, even if the length of the positioning pin 102 is set short, the fitting state of the positioning pin 102 with the positioning hole 91b can be maintained. By shortening the length of the positioning pin 102, the work of fitting the positioning pin 102 with the positioning hole 91b becomes easier.

[0055] 3 and 7, the spring holding portion 120 is configured by a reinforcing rib 121 formed on the operating member 50. In this way, since the reinforcing rib 121 of the operating member 50 configures (serves as) the spring holding portion 120, no separate member is required to configure this spring holding portion 120. Therefore, the spring holding portion 120 can be simplified.

[0056] Furthermore, as shown in FIG. 5, when the base end 91 of the leaf spring 90 is completely attached to the spring attachment surface 101, the free end 93 side of the leaf spring 90 is separated from the spring holding portion 120. Therefore, the operation of the operating member 50 is not affected. For example, when the lid 40 is in the fully closed state as shown in FIG. 1B and the operating member 50 is opened (swinged in the direction of the arrow R1), the stopper 53 and the tip 122 of the spring holding portion 120 shown in FIG. 3 also rotate in the same direction and approach the leaf spring 90. However, since the leaf spring 90 and the spring holding portion 120 are separated from each other (there is a gap), the spring holding portion 120 does not interfere with the leaf spring 90 even when the operating member 50 is operated. Therefore, the operation of the operating member 50 is not affected.

[0057] 1 to 8, the locking device 10 is configured to be able to lock a second member 40 (lid 40), which is rotatably supported on a first member 30 (storage main body 30), to the first member 30. The locking device 10 includes an operating member 50 rotatably supported on the second member 40, a latch 70 provided on the operating member 50, a striker 80 provided on the first member 30 so as to be able to engage with the latch 70, and a leaf spring 90 that biases the second member 40 in an opening direction R2 (arrow R2 direction) relative to the striker 80 when the latch 70 is engaged with the striker 80.

[0058] The leaf spring 90 has a base end 91 that can be assembled to the second member 40, and a tip end 93 that is a free end 93 that can abut against the striker 80. The base end 91 has a positioning hole 91b that penetrates in the plate surface direction of the leaf spring 90. The second member 40 has a spring mounting surface 101 on which the base end 91 can be overlapped, and a positioning pin 102 that can be fitted into the positioning hole 91b of the base end 91 overlapping the spring mounting surface 101. The operating member 50 has a spring holding portion 120 that can temporarily hold the free end 93 side of the leaf spring 90 when assembled to the second member 40. The spring holding portion 120 faces the leaf spring 90 so as to be able to hold the weight of the free end 93 side of the leaf spring 90 in the case of a temporary assembly state in which the base end 91 overlaps the spring mounting surface 101 in the upward state. When the base end 91 of the leaf spring 90 is completely attached to the spring attachment surface 101, the free end 93 side of the leaf spring 90 is separated from the spring holding portion.

[0059] 7 and 8, when the leaf spring 90 is assembled to the spring mounting portion 100 of the lid 40, the spring mounting surface 101 of the spring mounting portion 100 is placed in an upward position. In the case of a temporary assembly state in which the base end 91 of the leaf spring 90 is placed on top of the spring mounting surface 101 in the upward position, the positioning hole 91b of the base end 91 is aligned with the positioning pin 102 and fitted in.

[0060] However, in the case of a temporary assembly in which the base end 91 of the leaf spring 90 is placed on top of the spring mounting surface 101 facing upward, the free end 93 of the leaf spring 90 tends to fall downward due to its own weight.

[0061] In response to this, by temporarily holding the free end 93 side of the leaf spring 90 by the spring holding portion 120, it is possible to prevent the free end 93 side from falling. Therefore, the temporarily assembled state of the base end 91 of the leaf spring 90 with respect to the spring mounting surface 101 can be stably maintained. As a result, it is possible to prevent the leaf spring 90 from falling off the spring mounting surface 101. Since the positioning hole 91b does not come off the positioning pin 102, the position of the leaf spring 90 with respect to the spring mounting surface 101 can be reliably maintained.

[0062] In this manner, the leaf spring 90 can be easily and reliably maintained in a provisionally assembled state on the spring mounting surface 101 by a single process of simply stacking the base end 91 of the leaf spring 90 on the spring mounting surface 101 facing upward and fitting the positioning hole 91b of the base end 91 onto the positioning pin 102. Thereafter, the base end 91 of the leaf spring 90 can be completely attached to the spring mounting surface 101 by the fixing means 110. As a result, the efficiency of the assembly work of the locking device 10 and the number of assembly steps can be improved.

[0063] Moreover, as shown in FIG. 5, when the base end 91 of the leaf spring 90 is completely attached to the spring mounting surface 101, the free end 93 side of the leaf spring 90 is moved away from the spring holding portion 120, so that the biasing force of the leaf spring 90 can be stabilized.

[0064] As long as the functions and effects of the present invention are achieved, the present invention is not limited to the examples. For example, the shape of the latch 70 is not limited to an inverted L-shape, but may be, for example, a U-shape. [Industrial Applicability]

[0065] The locking device 10 of the present invention is suitable for use as a glove box for a vehicle. [Explanation of symbols]
