Description

Technical Field

[0001] The present disclosure relates to an opening / closing body locking device for keeping an opening / closing body such as a lid provided in a glove box in a closed state. Background Art

[0002] A glove box is installed in a position of an instrument panel of a passenger car that is opposite to a passenger seat in the front-rear direction of the passenger car. The glove box is provided with an opening and closing body locking device for keeping a lid of the glove box closed. When a passenger presses a button for opening the lid, the holding of the opening and closing body locking device is released and the lid opens.

[0003] As an example of an opening and closing body locking device, a housing, two rods, a coil spring and a support are provided. The housing supports the two rods so that they can be inserted into the housing and pulled out from the housing. The housing guides the two rods to be inserted into the extension direction of the rods so that the rods are close to each other and to be pulled out so that the rods are separated from each other.

[0004] The coil portion of the coil spring is fitted on the support. One axial end of the coil portion is connected to a rod via an arm. The other axial end of the coil portion is connected to another rod via another arm. The coil portion of the coil spring applies force to the two rods in the extraction direction. And, when one rod overcomes the force of the coil spring and is inserted, the housing guides the support in the introduction direction orthogonal to the insertion direction. Along with this, the other rod is inserted into the housing. When the action force of the insertion rod is released from one rod, the two rods move in the extraction direction with the action force of the coil spring. At this time, the housing guides the support in the push-out direction opposite to the introduction direction (for example, refer to patent document 1).

[0005] Patent Document 1: Chinese Utility Model Specification No. 206681536 Summary of the invention Problems to be solved by the invention

[0006] The above-mentioned opening and closing body locking device inputs the action force for inserting the rod into the shell from the arm connected to the rod to one end of the spiral part. Even if the action force is only input to one end of the spiral part, it is difficult for the spiral part mounted on the pillar to produce a wavy or spiral torsion on the axis of the spiral part. On the other hand, since the action force is only input to one end of the pillar, the pillar itself, which is mounted with the spiral part, tilts the axis of the pillar quite a bit depending on the different inputs at both ends of the pillar. Such inclination of the pillar causes the pillar moving in the introduction direction and the push-out direction to get stuck, and causes the rod moving in the insertion direction and the extraction direction to get stuck. Therefore, in the above-mentioned opening and closing body locking device, it is expected that the operability brought about by the smooth movement of the rod will be improved.

[0010] An embodiment of an opening and closing body locking device is described below. An example of an opening and closing body is a glove box. The opening and closing body locking device keeps a lid of the glove box in a closed state. The opening and closing body locking device releases the closed state by operating the glove box.

[0011] [Opening and closing body locking device 10] like Figure 1 As shown, the opening and closing body locking device 10 includes a housing 11, two rods 21 and a coil spring 31 (see Figure 2 ).

[0012] The housing 11 has a box shape for accommodating the coil spring 31. The housing 11 has an upper surface opening 11A on the upper surface that communicates with the interior of the housing 11, and has a side opening 11B on each of the left and right sides. The coil spring 31 is accommodated in the interior of the housing 11 from the upper surface opening 11A. Each rod 21 is inserted into the interior of the housing 11 from the side opening 11B. The front wall 12 and the rear wall 13 of the housing 11 each have a rod locking hole 14 extending in the left-right direction DL. Each rod locking hole 14 passes through from the interior of the housing 11 to the outside of the housing 11. The housing 11 may be an integral resin molded product, or may be a combination of a resin molded body having a front wall 12 and a resin molded body having a rear wall 13.

[0013] Each rod 21 has a columnar shape extending in the left-right direction DL. One rod 21 has the same shape as the other rod 21. A straight line passing through the center of the left-right direction DL of the housing 11 and extending in the up-down direction DT is the center line LC. The two rods 21 are mounted on the housing 11 in a rotationally symmetrical manner with the center line LC as the rotation center. Each rod 21 is configured along the left-right direction DL in an extension direction of the rod 21. Each rod 21 is configured with a front end portion in the extension direction inside the housing 11. Each rod 21 is configured with a base end portion in the extension direction outside the housing 11. The two rods 21 are mounted on the housing 11 in a manner that allows insertion and removal along the extension direction of the rod 21.

[0014] The following mainly describes the configuration in Figure 1 The structure of the right side rod 21 is configured in Figure 1 In the structure of the rod 21 on the left side, the description of the structure common to the rod 21 arranged on the right side is omitted.

[0015] The base end of the rod 21 is provided with an inserting portion 22. The inserting portion 22 connects the cover opening and closing arm 51 (see Figure 7 ) is embedded in rod 21. The cover opening and closing arm 51 receives a holding force for holding the cover in a closed state from the opening and closing body locking device 10. The holding force is the force of the coil spring 31. The two rods 21 are pulled out from the housing 11 and move away from each other in the extending direction which is the left-right direction DL, thereby locking the state of the cover in a closed state.

[0016] The cover opening and closing arm 51 transmits the operating force F21 for opening the cover to the opening and closing body locking device 10. The operating force F21 is a force for inserting one rod 21 into the housing 11. The two rods 21 approach each other in the extending direction by being inserted into the housing 11, thereby releasing the lock of the cover state.

[0017] like Figure 2 As shown, the opening and closing body locking device 10 includes a coil spring 31 as an example of a connecting member. The coil spring 31 includes two arms 32 and a hollow coil portion 33 connected to the two arms 32. The coil spring 31 is accommodated inside the housing 11. When the coil spring 31 is accommodated inside the housing 11, one arm 32 is arranged on the right side of the coil portion 33. When the coil spring 31 is accommodated inside the housing 11, another arm 32 is arranged on the left side of the coil portion 33. When the coil spring 31 is accommodated inside the housing 11, the axis 3L of the coil portion 33 is arranged along the front-rear direction DF.

[0018] The rod 21 includes a rod body 23 and a pressing portion 25. The rod body 23 has a quadrangular prism shape extending in the left-right direction DL. The front side surface of the right rod body 23 includes a rod locking claw 24 protruding forward. The rod locking claw 24 is inserted into the rod locking hole 14 of the housing 11. The engagement between the rod locking hole 14 and the rod locking claw 24 limits the moving direction of the rod 21 in the left-right direction DL. The rod locking hole 14 limits the moving range of the rod locking claw 24 in the left-right direction DL, thereby limiting the moving range of the rod 21 in the left-right direction DL.

[0019] The rear side surface of the rod body 23 on the right side is provided with a force-applying piece 23S protruding rearward. The force-applying piece 23S has a cantilever beam shape extending along the extension direction of the rod 21. One end of the force-applying piece 23S in the extension direction is a fixed end fixed to the front end portion of the rod body 23. The other end of the force-applying piece 23S in the extension direction is a free end that is force-applied toward the inner surface of the housing 11. The force applied to the free end of the force-applying piece 23S is accompanied by the movement of the rod 21, and the front side surface of the rod body 23 is pressed against the front inner surface of the housing 11 while the free end of the force-applying piece 23S is continuously in sliding contact with the rear inner surface of the housing 11. Thus, the force-applying piece 23S stabilizes the position of the rod 21 in the front-to-back direction DF in the housing 11.

[0020] The front end of the rod body 23 includes a hook portion 23T as an example of a connection portion. The hook portion 23T hooks the front end of the arm 32 of the coil spring 31. The position of the arm 32 of the coil spring 31 in the up-down direction DT and the left-right direction DL is fixed by the hook portion 23T of the rod 21.

[0021] The pressing portion 25 is integral with the front end of the rod body 23. The pressing portion 25 has a protruding piece that protrudes from the front end of the rod body 23 toward the extension direction and the introduction direction of the rod 21. The introduction direction is one of the up-down directions DT, i.e., the downward direction, which is orthogonal to the extension direction of the rod 21, i.e., the left-right direction DL and the front-back direction DF. The pressing portion 25 has a fan-shaped plate shape, and the fan-shaped plate shape has an edge extending along the extension direction of the rod 21 and an edge extending along the introduction direction. The end face of the pressing portion 25 has a curved surface 25S in the shape of an arc surface. The curved surface 25S in the shape of an arc surface connects an arc with a radius along the edge extending along the extension direction of the rod 21 or the edge extending along the introduction direction in the front-back direction DF.

[0022] The position of the right pressing portion 25 in the front-rear direction DF is closer to the front side than the center of the right lever body 23 in the front-rear direction DF (see Figure 6 The position of the left pressing portion 25 in the front-rear direction DF is offset to the rear side relative to the center of the left lever body 23 in the front-rear direction DF (see Figure 6 ).

[0023] [Internal Structure of the Opening and Closing Body Locking Device 10] like Figure 3 As shown, the housing 11 includes two main body guide walls 15 , one spiral guide wall 16 , and two arm guide walls 17 .

[0024] The main body guide wall 15 has a rectangular cylindrical shape extending along the left-right direction DL. The main body guide wall 15 includes a portion of the front wall 12 of the housing 11, a portion of the rear wall 13, an upper wall, and a lower wall 15A. The two main body guide walls 15 are provided on the housing 11 in a rotationally symmetrical manner with the center line LC as the rotation center. Hereinafter, the structure of one main body guide wall 15 will be mainly described, and in the structure of the other main body guide wall 15, the description of the structure common to the two main body guide walls 15 will be omitted.

[0025] The right main body guide wall 15 defines the side opening 11B on the right side of the housing 11. The right main body guide wall 15 extends from the right end of the housing 11 to the spiral guide wall 16. The right main body guide wall 15 has a size that allows the rod main body 23 to be inserted into the interior of the main body guide wall 15 and to be pulled out from the interior of the main body guide wall 15.

[0026] In the right main body guide wall 15, the portion constituting the rear wall 13 is provided with a sliding contact protrusion 11S extending in the left-right direction DL. The sliding contact protrusion 11S is arranged to face the force applying piece 23S of the rod 21 inserted into the main body guide wall 15. The force applying piece 23S and the sliding contact protrusion 11S slide in contact to stabilize the position of the rod 21 in the front-rear direction DF.

[0027] The portion of the left main body guide wall 15 that constitutes the rear wall 13 includes a rod locking hole 14 extending in the left-right direction DL. The rod locking hole 14 is arranged to face the rod locking claw 24 of the rod 21 inserted into the main body guide wall 15.

[0028] A pressing portion guide groove 5S extending along the left-right direction DL is provided on the lower wall 15A of the main body guide wall 15. The pressing portion guide groove 5S penetrates the lower wall 15A from the inside of the main body guide wall 15 toward the bottom of the housing 11. The pressing portion guide groove 5S provided on the right lower wall 15A opens at the right end of the housing 11 and is connected to the lower wall 15A over the entirety of the left-right direction DL of the main body guide wall 15. When the pressing portion 25 is inserted into the housing 11 from the right side of the housing 11, the pressing portion 25 passes through the pressing portion guide groove 5S on the right side.

[0029] The position of the right pressing portion guide groove 5S in the front-rear direction DF is closer to the front side than the center of the right main body guide wall 15 in the front-rear direction DF (see Figure 6The right pressing portion guide groove 5S enables the right pressing portion 25 to move in the left-right direction DL together with the right rod main body 23. The position of the left pressing portion guide groove 5S in the front-to-back direction DF is located to the rear of the center of the left main body guide wall 15 in the front-to-back direction DF (see Figure 6 ). The left pressing portion guide groove 5S enables the left pressing portion 25 to move in the left-right direction DL together with the left lever body 23 .

[0030] return Figure 3 The spiral guide wall 16 has a rectangular cylindrical shape that rises from the lower wall of the housing 11 along the vertical direction DT. The spiral guide wall 16 includes a portion of the front wall 12 of the housing 11, a portion of the rear wall 13, a left wall 16L, and a right wall 16R (see Figure 6 ). The spiral guide wall 16 is an example of a restricting portion. The spiral guide wall 16 is arranged at the center of the housing 11 in the left-right direction DL. The two main body guide walls 15 are arranged to sandwich the spiral guide wall 16 in the left-right direction DL.

[0031] The interior of the spiral portion guide wall 16 communicates with the upper surface opening 11A of the housing 11. The spiral portion 33 accommodated in the housing 11 is arranged inside the spiral portion guide wall 16 from the upper surface opening 11A of the housing 11.

[0032] The left wall 16L of the spiral guide wall 16 is provided with an opening 16S communicating with the pressing portion guide groove 5S on the left side. The pressing portion 25 inserted along the pressing portion guide groove 5S on the left side enters the interior of the spiral guide wall 16 through the opening 16S. The right wall 16R of the spiral guide wall 16 is also provided with an opening 16S communicating with the pressing portion guide groove 5S on the right side. The pressing portion 25 inserted along the pressing portion guide groove 5S on the right side also enters the interior of the spiral guide wall 16 through the opening 16S.

[0033] The arm guide walls 17 extend upward from the lower wall of the housing 11 toward the left and right sides, respectively. The two arm guide walls 17 are arranged so as to sandwich the spiral guide wall 16 in the left-right direction DL. The two arm guide walls 17 are provided on the housing 11 in a rotationally symmetrical manner with the center line LC as the rotation center. Hereinafter, the structure of one arm guide wall 17 will be mainly described, and in the structure of the other arm guide wall 17, the description of the structure common to the two arm guide walls 17 will be omitted.

[0034] The left arm guide wall 17 is arranged on the left side of the spiral guide wall 16 and in front of the left pressing portion guide groove 5S. That is, the left arm guide wall 17 is arranged in front of the pressing portion 25 inserted into the left pressing portion guide groove 5S. The left arm guide wall 17 includes a part of the front wall 12 of the housing 11. The left arm guide wall 17 forms a gap between the front wall 12 of the housing 11 and the left pressing portion guide groove 5S. The left arm guide wall 17 includes an inclined surface 17S extending from the lower wall of the spiral guide wall 16 toward the upper side and the left side.

[0035] The right arm guide wall 17 is arranged on the right side of the spiral guide wall 16 and at a position behind the right pressing portion guide groove 5S. That is, the right arm guide wall 17 is arranged at a position behind the pressing portion 25 inserted into the right pressing portion guide groove 5S. The right arm guide wall 17 has an inclined surface 17S extending upward and rightward from the lower wall of the spiral guide wall 16.

[0036] like Figure 4 As shown, when the spiral portion 33 is arranged at the upper end inside the spiral portion guide wall 16, the left arm 32 is hooked on the hook portion 23T of the left rod body 23. The left arm 32 enters the inside of the left arm guide wall 17 and approaches the upper end of the left inclined surface 17S.

[0037] The angle formed by the extending direction of the inclined surface 17S and the left-right direction DL is larger than the angle formed by the extending direction of the arm 32 of the coil spring 31 disposed at the upper end of the spiral portion guide wall 16 and the left-right direction DL. The left arm 32 is disposed so that when the spiral portion 33 moves further inward from the upper end of the spiral portion guide wall 16, the left arm 32 abuts against the upper end of the inclined surface 17S. The upper end of the inclined surface 17S has such a shape that when the left arm 32 abutting against the inclined surface 17S moves further downward, the arm 32 is moved in the insertion direction while the arm 32 is rotated so that the extending direction of the arm 32 faces the extending direction of the inclined surface 17S.

[0038] As the spiral portion 33 moves further inward from the upper end of the spiral portion guide wall 16 , the left arm 32 rotates so that the extending direction of the arm 32 approaches the extending direction of the left inclined surface 17S.

[0039] like Figure 5As shown, when the spiral portion 33 is arranged at the upper end portion inside the spiral portion guide wall 16, the curved surface 25S of the pressing portion 25 on the left side abuts against the upper left side portion of the outer peripheral surface of the spiral portion 33. When the pressing portion 25 on the left side is further inserted in the right direction, the curved surface 25S of the pressing portion 25 on the left side may press the outer peripheral surface of the spiral portion 33 to press the spiral portion 33 in the introduction direction, or may not press. In the present embodiment, the pressing portion 25 on the left side does not press the outer peripheral surface of the spiral portion 33 when it is inserted in the right direction. In addition, the pressing portion 25 on the left side may or may not abut against the outer peripheral surface of the spiral portion 33 when it is inserted in the right direction. In the present embodiment, the pressing portion 25 on the left side abuts against the outer peripheral surface of the spiral portion 33 when it is inserted in the right direction.

[0040] In addition, when the spiral portion 33 is arranged at the upper end portion inside the spiral portion guide wall 16, the curved surface 25S of the right pressing portion 25 abuts against the upper right portion of the outer peripheral surface of the spiral portion 33. When the right pressing portion 25 is further inserted in the left direction, the curved surface 25S of the right pressing portion 25 presses the outer peripheral surface of the spiral portion 33 to press the spiral portion 33 in the introduction direction.

[0041] At this time, the insertion of the left pressing portion 25 is guided by the left pressing portion guide groove 5S along the left-right direction DL. The insertion of the right pressing portion 25 is guided by the right pressing portion guide groove 5S along the left-right direction DL. In addition, the introduction of the spiral portion 33 is guided by the spiral portion guide wall 16 along the up-down direction DT.

[0042] like Figure 6 As shown in FIG. 1 , when the spiral portion 33 is arranged at the upper end of the spiral portion guide wall 16, the position of the left pressing portion 25 in the front-to-back direction DF is biased toward the rear side relative to the center of the outer peripheral surface of the spiral portion 33 in the front-to-back direction DF. The position of the right pressing portion 25 in the front-to-back direction DF is biased toward the front side relative to the center of the outer peripheral surface of the spiral portion 33 in the front-to-back direction DF. In this way, the pressing portions 25 of the rods 21 are arranged in the direction in which the axis 3L of the spiral portion 33 extends. And, the pressing of the spiral portion 33 by the pressing portion 25 of the right rod 21 acts on the coil spring 31.

[0043] When the left pressing portion 25 is inserted to the right, the curved surface 25S of the left pressing portion 25 maintains the position in the front-rear direction DF and moves to the right while contacting the outer peripheral surface of the spiral portion 33. When the right pressing portion 25 is further inserted to the left, the curved surface 25S of the right pressing portion 25 maintains the position in the front-rear direction DF and moves to the left while pressing the outer peripheral surface of the spiral portion 33. In this way, the pressing of the spiral portion 33 by the pressing portion 25 of the right rod 21 continuously acts on the spiral spring 31.

[0044] [Function of the opening and closing body locking device 10] like Figure 7 As shown in the figure, when the lid of the glove box as an example of the opening and closing body is closed, the rod locking claw 24 of the right rod 21 is arranged at the right end of the rod locking hole 14 of the housing 11. In addition, the rod locking claw 24 of the left rod 21 is arranged at the left end of the rod locking hole 14 of the housing 11. The coil portion 33 of the coil spring 31 is arranged at the upper end of the inner part of the coil portion guide wall 16. The arm 32 of the coil spring 31 is hooked on the rod 21, and the force F31 in the right direction is applied to the right rod 21, and the force F31 in the left direction is applied to the left rod 21, that is, the force F31 in the pull-out direction is applied to each rod 21.

[0045] Thus, the coil spring 31 fixes the rod locking claw 24 of the right rod 21 to the right end of the right rod locking hole 14. The coil spring 31 fixes the rod locking claw 24 of the left rod 21 to the left end of the left rod locking hole 14. And, the opening and closing body locking device 10 locks the state of the cover in the closed state.

[0046] Here, when the operating force F21 that overcomes the acting force F31 acts on the right rod 21 through the cover opening and closing arm 51, the right rod 21 begins to be inserted into the housing 11. In addition, the rod locking claw 24 of the right rod 21 begins to move leftward from the right end of the rod locking hole 14 of the housing 11.

[0047] like Figure 8 As shown, the translation of the rod 21 caused by the insertion of the right rod 21 causes the right arm 32 connected to the right rod 21 and the spiral portion 33 to translate in the insertion direction, i.e., the left direction, while rotating so that the extension direction of the arm 32 approaches the introduction direction, i.e., the downward direction.

[0048] A part of the rotational force of the arm 32 received by the spiral portion 33 is converted into a reaction force that pushes the right rod 21 back in the extraction direction opposite to the insertion direction, that is, the right direction. Thus, the coil spring 31 applies an operating force suitable for inserting the right rod 21 to the right rod 21. In addition, a part of the rotational force of the arm 32 received by the spiral portion 33 causes the spiral portion 33 to move in the introduction direction, that is, the downward direction.

[0049] On the other hand, the translation of the pressing portion 25 caused by the insertion of the rod 21 on the right side causes the curved surface 25S of the pressing portion 25 to translate in the insertion direction, i.e., the left direction, while causing the curved surface 25S to slide in contact with the outer peripheral surface of the spiral portion 33. The curved surface 25S in the shape of an arc surface connects the arc with the edge extending in the extension direction of the rod 21 or the edge extending in the introduction direction as the radius in the front-back direction DF. Therefore, for the curved surface 25S of the pressing portion 25, by making the curved surface 25S slide in contact with the outer peripheral surface of the spiral portion 33, the spiral portion 33 is smoothly pushed in the introduction direction. In addition, the shape of such a curved surface 25S is such that the more the curved surface 25S is inserted together with the rod 21 on the right side, the smaller the displacement amount of the portion in sliding contact with the spiral portion 33 in the introduction direction.

[0050] In this way, the translation of the rod 21 caused by the insertion of the rod 21 causes the arm 32 connected to the rod 21 and the spiral portion 33 to translate in the insertion direction while rotating so that the extension direction of the arm 32 is oriented toward the introduction direction. The rotation force of the arm 32 received by the spiral portion 33 is converted into a reaction force that pushes the rod 21 back in the extraction direction opposite to the insertion direction and a force that moves the spiral portion 33 in the introduction direction. At this time, the right arm 32 rotates in such a way that the extension direction approaches the introduction direction, and the displacement amount of the arm 32 in the introduction direction is reduced as the right rod 21 is inserted. In addition, the curved surface 25S of the pressing portion 25 inserted together with the right rod 21 also reduces the displacement amount of the portion in sliding contact with the spiral portion 33 in the introduction direction as the right rod 21 is inserted. Therefore, the displacement amount of the spiral portion 33 in the introduction direction caused by the pressing portion 25 is easy to follow the displacement amount of the arm 32 in the introduction direction.

[0051] If the spiral portion 33 is displaced in the introduction direction, the arm 32 on the left side abuts against the inclined surface 17S on the left side. If the spiral portion 33 is further displaced in the introduction direction, the arm 32 on the left side rotates so that the extension direction of the arm 32 on the left side approaches the extension direction of the inclined surface 17S. That is, while the arm 32 on the left side is inserted in the right direction, the arm 32 on the left side is rotated so that the extension direction of the arm 32 on the left side faces the downward direction. Then, as the arm 32 on the left side is inserted in the right direction, the rod 21 on the left side is inserted in the right direction. Thus, the rod 21 on the left side is inserted in the introduction direction in accordance with the insertion of the rod 21 on the right side.

[0052] In addition, if the input of the operating force F21 from the right rod 21 is released, the two arms 32 move so that the angle formed by the two arms 32 is expanded. At this time, the position of the upper end of each arm 32 in the up-down direction DT is fixed to the position of the rod 21 in the up-down direction DT. Therefore, the two rods 21 are pulled out from the housing 11, and the spiral portion 33 moves in the upward direction as the pushing direction. In this way, the coil spring 31 moves in the push direction, which is the opposite direction to the introduction direction, so that the other rod 21 is pulled out in accordance with the pulling out of one rod 21.

[0053] [Effect] As described above, according to the above-mentioned embodiment, the following effects are obtained. (1) The pressing portion 25 of the rod 21 presses the spiral portion 33 in the introduction direction by the insertion of the rod 21. Therefore, the spiral portion 33 moves smoothly in the introduction direction to convert the insertion of one rod 21 into the insertion of another rod 21. As a result, the movement load of the rod 21 caused by the obstruction of the movement of the spiral spring 31 can be reduced, and the rod 21 can be smoothly moved in the extension direction. Therefore, according to the opening and closing body locking device 10 of the present disclosure, the operability of the opening and closing body locking device 10 is improved by the smooth movement of the rod 21.

[0054] (2) The pressing portion 25 of the right rod 21 presses the spiral portion 33 in the introduction direction by the insertion of the right rod 21. The pressing portion 25 of the left rod 21 may also press the spiral portion 33 in the introduction direction by the insertion of the left rod 21.

[0055] At this time, since the two pressing parts 25 are arranged in the extending direction of the axis 3L of the spiral part 33, the pressing of the spiral part 33 by the two pressing parts 25 acts on the spiral part 33 from two positions in the extending direction of the spiral part 33. Therefore, the pressing of the spiral part 33 by the pressing parts 25 is unlikely to tilt the axis 3L of the spiral part 33, so the spiral part 33 can be moved more smoothly in the introduction direction.

[0056] (3) The curved surface 25S of the pressing portion 25 is inserted into the housing 11 together with the rod 21 while slidingly contacting the spiral portion 33. Then, the spiral portion 33 is moved in the introduction direction by the curved surface 25S of the pressing portion 25 pressing the spiral portion 33. Therefore, the movement of the spiral portion 33 is performed more smoothly in conjunction with the insertion of the rod 21. As a result, the movement of the rod 21 is performed more smoothly.

[0057] (4) Since the pressing portion 25 and the rod body 23 are integrally formed, the number of components of the opening and closing body locking device 10 can be reduced compared to a case where the pressing portion 25 and the rod body 23 are separate bodies.

[0058] (5) When the extension direction of the rod 21 inserted is orthogonal to the introduction direction of the spiral portion 33, the spiral portion 33 is difficult to move in the introduction direction because the direction of the operating force F21 for inserting the rod 21 is orthogonal to the introduction direction of the spiral portion 33. Therefore, when the opening and closing body locking device 10 in which the extension direction of the rod 21 is orthogonal to the introduction direction is provided with the pressing portion 25, the smoothing of the movement of the rod 21 according to the above (1) to (4) becomes a more significant effect.

[0059] (6) The coil spring 31 urges the two rods 21 in the removal direction. Therefore, when the operating force F21 for inserting the rod 21 into the housing 11 is released from the rod 21, the urging force F31 of the coil spring 31 moves the two rods 21 in the removal direction. As a result, the removal of the two rods 21 becomes easy.

[0060] (7) Since the coil guide wall 16 restricts the movement of the coil 33 in the introduction direction and the push-out direction, the movement direction of the coil spring 31 can be stabilized. (8) The two pressing parts 25 press the outer peripheral surface of the spiral part 33 in the introduction direction by inserting the two rods 21. At this time, since the two pressing parts 25 are arranged along the axis 3L of the spiral part 33, the pressing of the pressing parts 25 acts on the outer peripheral surface of the spiral part 33 from two positions arranged along the axis 3L of the spiral part 33. Therefore, even if the spiral part 33 is a hollow body that is easily bent, the spiral part 33 can be smoothly moved in the introduction direction.

[0061] (9) If the inserted pressing portion 25 excessively presses the spiral portion 33 in the introduction direction and causes the spiral portion 33 to excessively displace in the introduction direction, the excessively displaced spiral portion 33 and the rod 21 that moves little by little in the insertion direction will apply a large tension to the arm 32. On the contrary, if the pressing portion 25 does not press the spiral portion 33 sufficiently, the spiral portion 33 that is difficult to displace in the introduction direction and the rod 21 that moves little by little in the insertion direction will apply a large compressive force to the arm 32.

[0062] In this regard, the curved surface 25S of the pressing portion 25 displaces the spiral portion 33 in the introduction direction by pressing to follow the displacement of the arm 32 in the introduction direction. Therefore, the load applied to the arm 32 and the movement load of the rod 21 caused by the load applied to the arm 32 can be reduced.

[0063] The above-mentioned embodiment can also be modified and implemented as follows. [Pressing portion 25] The coil portion 33 of the coil spring 31 may be fitted on the support column. The support column may extend orthogonally to the insertion direction of the rod 21 and the introduction direction of the coil spring 31.

[0064] ·like Fig. 9 As shown, the support column with the spiral portion 33 may be inserted into the synchronization slit 25S1 formed in the pressing portion 25. At this time, the support column with the spiral portion 33 may be pressed in the introduction direction by the circumference defining the synchronization slit 25S1 in the pressing portion 25. In addition, the pressing portion 25 may omit the curved surface 25S.

[0065] like Fig. 9As shown by the solid line, for example, the pressing portion 25 on the right side has a synchronous slit 25S1, which is composed of a groove extending to the left and a groove extending from the front end of the groove to the upper left side. The synchronous slit 25S1 formed in the pressing portion 25 on the right side is inserted through the front end of the support 35 on which the spiral portion 33 is mounted. Fig. 9 As shown by the double-dotted line, for example, the left pressing portion 25 has a synchronous slit 25S1, which is composed of a groove extending to the right and a groove extending from the front end of the groove to the upper right side. The synchronous slit 25S1 formed in the left pressing portion 25 is inserted through the rear end of the support 35 on which the spiral portion 33 is mounted.

[0066] Here, if the action force F21 for inserting the right pressing part 25 in the left direction is input to the right pressing part 25, the right synchronization slit 25S1 moves in the left direction together with the right pressing part 25. The peripheral surface of the right synchronization slit 25S1 moving in the left direction presses the support 35 in the introduction direction. If the support 35 is pressed down in the introduction direction, the support 35 presses the peripheral surface of the left synchronization slit 25S1 to move the left synchronization slit 25S1 in the right direction. In addition, the left arm 32 is inserted into the left pressing part 25 in the right direction by the spiral part 33 fitted on the support 35 moving in the introduction direction. As a result, the insertion of the right rod 21 is synchronized with the insertion of the left rod 21 via the left and right pressing parts 25.

[0067] In addition, if Fig.10 As shown in FIG. 1 , when the support 35 reaches the slot extending to the left in the right synchronization slot 25S1, the support 35 is stopped from being pressed down in the introduction direction. Then, when the input of the operating force F21 is released, the force of the coil spring 31 causes the two pressing parts 25 to move away from each other in the left-right direction DL. As a result, the support 35 starts to move in the push-out direction, and the two rods 21 start to be pulled out from the housing 11.

[0068] The two rods 21 may include the pressing portion 25 on one of the rods 21 , and omit the pressing portion 25 from the other rod 21 . The pressing portion 25 may be a separate body from the rod body 23 , and may be connected to the rod body 23 so as to be inserted in conjunction with the insertion of the rod body 23 and to be pulled out in conjunction with the removal of the rod body 23 .

[0069] The extending direction of the rod 21 may be a direction other than the direction orthogonal to the introducing direction and may be a direction intersecting the introducing direction. The operating force F21 input to the rod 21 may be input to the right rod 21 , may be input to the left rod 21 , or may be input to both rods 21 .

[0070] [Connecting parts] The coil spring 31 may also urge the two rods 21 in the insertion direction. Even in this structure, the two rods 21 are connected to the coil spring 31 in such a manner that the other rod 21 is drawn in in accordance with the insertion of one rod 21. In addition, the two rods 21 are connected to the coil spring 31 in such a manner that the other rod 21 is pulled out in accordance with the withdrawal of one rod 21.

[0071] The connecting member may also be a connecting rod mechanism connected to the two rods 21. The connecting rod mechanism converts the insertion of one rod 21 into the insertion of the other rod 21 and the movement of the connecting rod mechanism in the introduction direction. The connecting rod mechanism converts the extraction of one rod 21 into the extraction of the other rod 21 and the movement of the connecting rod mechanism in the push-out direction. The connecting member may also be a combination of a spring that applies force to the two rods 21 in the insertion direction or a spring that applies force to the two rods 21 in the pull-out direction and a connecting rod mechanism. For example, the connecting rod mechanism may also include a connecting rod connected to one rod 21, another connecting rod connected to the other rod 21, and a joint that connects the two connecting rods in a V shape. Furthermore, a joint may also rotatably connect another connecting rod to one connecting rod, and move in the introduction direction and the push-out direction.
