Description

Technical Field

[0001] The present invention relates to a stop device disposed between a fixed member and a movable member that moves toward / away from the fixed member. Background Technology

[0002] For example, a movable component such as a rear door is installed at the opening of a fixed component such as the car body on the trunk side of the vehicle, in a manner that allows it to be opened and closed. In most cases, a stop device is provided between the movable component and the fixed component to prevent direct collision between the movable component and the fixed component and to suppress impact.

[0003] As a stop device as described above, Patent Document 1 below describes a buffer device having a self-adjustable stop member, wherein the stop member has: a socket, which is generally cylindrical; a ring, which is rotatably attached to the socket; and a buffer head, which is housed in the ring in a liftable manner.

[0004] A claw is formed on the outer periphery of the bearing to prevent the ring from slipping off. Furthermore, an annular flange protrudes from the upper outer periphery of the ring, and a protruding piece with an inclined surface (thrust ramp) protrudes from the lower end of the ring, with a notch formed above the protruding piece. The claw on the outer periphery of the bearing engages with this notch, thereby preventing the ring from slipping off and holding it in place. Additionally, a groove is formed on the inner periphery of the ring, which engages with a groove formed on the outer periphery of the shaft of the buffer head.

[0005] Furthermore, when the ring is rotated, the ring rises through the inclined surface of the tab, and simultaneously, the shaft of the buffer head that engages with the groove rises, causing the buffer head as a whole to rise.

[0008] Patent Document 1: US9580951B2 Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] In the buffer device of Patent Document 1, when rotating the ring, it is necessary to grasp the flange on the outer periphery of the upper end of the ring, which protrudes from the upper opening of the bearing, to rotate the ring directly. At this time, the ring rises and rotates while passing through the inclined surface of the tab. Therefore, during the rotation operation of the ring, the upward thrust from the ring will act on the operator's hand, and it cannot be said that the ring is easy to operate.

[0011] Therefore, the object of the present invention is to provide a stop device that improves the operability of a rotating member when adjusting the amount of protrusion of the abutment portion relative to a fixed member or a moving member and fixing its position.

[0012] Solution for solving the problem

[0013] To achieve the above objectives, the present invention provides a stopping device disposed between a fixed member and a movable member that moves toward / away from the fixed member. The stopping device is characterized by comprising: a base member fixed to either the fixed member or the movable member; a shaft member having an abutment portion for abutting against either the fixed member or the movable member, and housed within the base member in a state of restricted rotation and in a vertically movable manner; a rotating member mounted to the base member in a manner rotatable relative to the base member but not vertically movable relative to the base member; and a gear member inside the rotating member, configured to restrict rotation relative to the rotating member. The system is configured with a temporary fixing part between the shaft member and the gear member, which temporarily fixes the gear member to the shaft member; and a cam mechanism between the base member and the gear member, which consists of a cam ramp and a cam abutment part that abuts against the cam ramp. The gear member is raised by rotating the rotating member in a predetermined direction. The gear member is configured to maintain the temporary fixed state of the shaft member achieved by the temporary fixing part by rotating in conjunction with the rotation of the rotating member, while raising the shaft member by the cam mechanism. The gear member also has a permanent fixing part that restricts the lifting and lowering movement of the shaft member in the raised state.

[0014] Invention Effects

[0015] According to the present invention, when the movable member is brought close to the fixed member, either the fixed member or the movable member abuts against the abutment portion, and the shaft member temporarily fixed by the temporary fixing portion is pressed in via the abutment portion. Then, after the movable member is moved away from the fixed member, when the rotating member is rotated, the gear member rotates in conjunction with it, and while maintaining the temporary fixed state of the shaft member, the shaft member is raised via a cam mechanism. Furthermore, the lifting and lowering movement of the shaft member is restricted by the permanent fixing portion of the gear member, thus adjusting the protrusion of the abutment portion and fixing its position. Moreover, during the rotation operation of the rotating member, the rotating member itself does not rise or fall relative to the base member; only the gear member rises inside the rotating member. Therefore, during the rotation operation of the rotating member, no unnecessary force is applied to the operator, improving the operability of the rotating member. Attached Figure Description

[0049] (One embodiment of the stop device)

[0050] The following is for reference Figures 1 to 18 An embodiment of the stop device of the present invention will be described.

[0051] like Figure 13 and Figure 14 As shown, the stop device 10 is disposed between the fixed member 1 and the movable member 5, which moves toward / away from the fixed member 1, to prevent the movable member 5 from directly colliding with the fixed member 1 when it moves toward the fixed member 1, thereby suppressing impact. Furthermore, a fixing hole 3 is formed in the fixed member 1 (see reference). Figure 1 ).

[0052] Fixed components 1 can include, for example, vehicle body panels, vehicle body frames, glove box housings, etc. Moving components 5 can include, for example, vehicle doors (including sliding doors, hatchback doors, rear doors, etc.), glove box lids, engine hoods, etc.

[0053] like Figure 1 As shown, the stopping device 10 of this embodiment is mainly composed of the following components: a base member 20, fixed to the fixing member 1; a shaft member 50, having an abutment portion 54 for abutting against the moving member 5, and housed in the base member 20 in a state of restricted rotation and in a manner that allows for lifting and lowering; a rotating member 60, mounted to the base member 20 in a manner that allows rotation relative to the base member 20 but prevents lifting and lowering relative to the base member 20; a gear member 80, disposed inside the rotating member 60 in a state of restricted rotation relative to the rotating member 60; and a sealing ring 100, disposed between the rotating member 60 and the fixing member 1, and in the form of an annulus.

[0054] Furthermore, the stop device 10 has: a temporary fixing part disposed between the shaft member 50 and the gear member 80, which temporarily fixes the gear member 80 to the shaft member 50 so that the shaft member 50 can be pressed into the abutment part 54 in the direction of approaching the fixing member 1; and a cam mechanism disposed between the base member 20 and the gear member 80, which is composed of a cam inclined surface 39 and a cam abutment part 89a abutting against the cam inclined surface 39, which causes the gear member 80 to rise by rotating the rotating member 60 in a predetermined direction.

[0055] It should be noted that the "lifting" of shaft member 50 and gear member 80 refers to the rotational axis C of rotating member 60 relative to base member 20 (see reference). Figure 2 The axis moves back and forth in the direction of the rotation axis (direction of the rotation axis). "Up" means moving in the direction of arrow C1 pointing to one end of the rotation axis (moving away from the fixed member 1), and "Down" means moving in the direction of arrow C2 pointing to the other end of the rotation axis (moving closer to the fixed member 1).

[0056] In addition, such as Figure 2 As shown, by rotating the rotating member 60 relative to the base member 20 in the direction indicated by arrow R1, the gear member 80 can be rotated in conjunction (follow-up rotation) to raise the gear member 80, and the shaft member 50 can also be raised (details will be described later). In the following description, the rotation direction of the rotating member 60 at this time (the rotation direction in which the rotating member 60 is rotated to raise the gear member 80 via the cam mechanism) will also be referred to as "rotation direction R1" or "R1 direction".

[0057] On the other hand, after rotating the rotating member 60 in the R1 direction, by rotating the rotating member 60 in the R1 direction... Figure 2 Rotating in the direction indicated by arrow R2 (opposite to the rotation direction R1) causes the gear component 80 to rotate accordingly, thereby lowering the gear component 80 back to its initial state (details will be described later). In the following description, the rotation direction of the rotating component 60 at this time will also be referred to as the "return direction R2" or "R2 direction".

[0058] It should be noted that, for ease of understanding and convenience, the accompanying drawings are... Figure 10 and Figure 11 Only the base component 20 and the gear component 80 are shown in the diagram. Figure 12 Only the shaft member 50 and the gear member 80 are shown in the figure.

[0059] First, the base component 20 will be explained.

[0060] Simultaneously refer to Figure 3 The base component 20 of this embodiment includes: a base body 21 for insertion into the fixing hole 3, which is cylindrical with a bottom; a flange portion 23 provided on the outer periphery of the top end side of the base body 21, disposed on the surface side of the fixing component 1 (the side opposite to the moving component 5), which is approximately annular; and a rotating component mounting portion 25 provided on the side opposite to the base body 21 through the flange portion 23, for the rotating component 60 to be fitted.

[0061] The base body 21 has a pair of opposing sidewalls 21a, 21a and a pair of opposing sidewalls 21b, 21b arranged orthogonally to the pair of sidewalls 21a, 21a. The outer surfaces of the two sidewalls 21a, 21a are flat surfaces that are parallel to each other. In addition, the outer surface of each sidewall 21b is a curved surface that conforms to the inner circumference of the fixing hole 3.

[0062] Furthermore, a pair of locking tabs 29, 29 are provided extending from the outer surface of a pair of sidewalls 21a, 21a and from the base end side (bottomed end side) of the sidewalls 21a. These locking tabs 29, 29 extend obliquely outward toward the flange portion 23 in an anchor-like manner. A stepped locking step portion 29a is formed on the outer surface of the tip side of each locking tab 29 in the extending direction. Furthermore, as... Figure 13 As shown, the base component 20 is fixed to the fixing hole 3 by locking the locking step portions 29a, 29a of a pair of locking pieces 29, 29 to the back periphery of the fixing hole 3.

[0063] Furthermore, on the inner side of the base member 20, a shaft receiving portion 27 is formed in the height direction (along the axial direction of the shaft member 50) of the base member 20, extending throughout the base body 21, flange portion 23, and rotating member mounting portion 25, to accommodate and hold the shaft member 50 for vertical movement. This shaft receiving portion 27 has a pair of inner surfaces 27a, 27a at positions corresponding to a pair of sidewalls 21a, 21a of the base body 21. These inner surfaces 27a, 27a are parallel to each other and are flat. Through these inner surfaces 27a, 27a, the shaft member 50 is accommodated within the base member 20 in a state where rotation is restricted (details will be explained in the description of the shaft member 50). Furthermore, recesses 27b, 27b are formed on the inner surfaces of the shaft receiving portion 27 at positions corresponding to a pair of sidewalls 21b, 21b of the base body 21. These recesses 27b, 27b extend along the height direction of the base member 20 and are groove-shaped. The threaded groove portion of the shaft member 50, described later, consisting of multiple teeth 57, and the locking claws 55 are movably inserted into these recesses 27b, 27b (see reference). Figure 14 , Figure 16 , Figure 18 ).

[0064] In addition, such as Figure 3 As shown, shaft locking holes 28 are formed on the upper opening side of the shaft receiving portion 27 of each recess 27b. Each shaft locking hole 28 is provided to penetrate radially in the rotating member mounting portion 25. Figure 14 As shown, a pair of locking claws 55, 55, described later, of the shaft member 50 are locked into a pair of shaft locking holes 28, 28, thereby preventing the shaft member 50 from being dislodged relative to the base member 20.

[0065] Moreover, such as Figure 4 As shown, a stepped portion 31 is formed on the back side (the side closest to the fixing member 1) and on the outer peripheral edge of the flange portion 23. (See also...) Figure 7 A pair of protrusions 32 and 33 are provided protruding from the stepped portion 31 at a position matching one sidewall 21b of the base body 21. Furthermore, a conical surface 32a is formed on one side of the protrusion 32, and a rotation-limiting surface 33a (see reference) is formed on one side of the protrusion 33 (the side opposite to the conical surface 32a), which is upright in the surface direction relative to the flange portion 23. Figure 4 Moreover, such as Figure 7 As shown, a protrusion 34 protrudes from the stepped portion 31 at a position matching the other side wall 21b of the base body 21. Conical surfaces 34a and 34b are formed on both sides of this protrusion 34 (see reference). Figure 7 ).

[0066] It should be noted that, as Figure 7 , Figure 8As shown, the plurality of anti-detachment protrusions 67 of the rotating member 60, described later, are locked in place with the stepped portion 31 in a manner that allows them to slide into contact with the stepped portion 31. Thus, the rotating member 60 is prevented from detaching and held in place in the base member 20 in a manner that allows it to rotate relative to the base member 20. Furthermore, the relationship between the anti-detachment protrusions 67 and the protrusions 32, 33, and 34 may change. These details will be explained in detail in the description of the rotating member 60.

[0067] like Figure 3 , Figure 4 as well as Figure 7 As shown, a plurality of notches 35 (three in this case) are formed on the outer periphery of the flange portion 23 at uniform intervals in the circumferential direction. Each notch 35 is a portion through which the corresponding anti-detachment protrusion 67 of the rotating member 60 passes when the rotating member 60 is mounted to the base member 20.

[0068] like Figure 3 As shown, the outer periphery of the rotating member mounting portion 25 is circular, and the outer periphery provides access for the cylindrical wall 61 of the rotating member 60 (described later). Figure 1 The gear mounting portion 25 is configured such that a predetermined portion of its outer periphery is hollowed out radially inward toward the rotating component mounting portion 25, thereby providing a gear mounting portion 37 for mounting the gear component 80. (Example:) Figure 10 As shown, the gear member 80 is arranged in the gear arrangement section 37 before the rotating member 60 rotates in the R1 direction to raise the shaft member 50. It should be noted that when the gear member 80 is arranged in the gear arrangement section 37, the outer peripheral surface of the rotating member mounting section 25 is substantially flush with the outer peripheral surface of the gear member 80.

[0069] Furthermore, a cam slope 39 is formed on the part of the rotating member mounting portion 25 located on the rotation direction R1 side of the gear mounting portion 37 (see reference). Figure 3 The cam ramp 39 protrudes in a shape that gradually increases in height relative to the surface of the flange portion 23 along the rotation direction R1. Furthermore, with the gear member 80 disposed in the gear mounting portion 37, when the rotating member 60 is rotated in the R1 direction, the gear member 80 rises via the cam ramp 39 (see reference). Figure 10 and Figure 11 ).

[0070] Furthermore, a gear upper crawling surface 41 is formed at the position where the rotating member mounting portion 25 is adjacent to the top 39a of the cam inclined surface 39, and the height of the gear upper crawling surface 41 from the surface of the flange portion 23 is set to be constant. Through this gear upper crawling surface 41, the height of the rising gear member 80 is maintained (see reference). Figure 11It should be noted that a conical gear abutment surface 41a is formed at one circumferential end (the end on the R1 direction side) of the gear's crawling surface 41 (see reference). Figure 3 The gear member 80 is positioned in its raised state by having its cam abutment portion 89a abut against the gear abutment surface 41a. Furthermore, as... Figure 3 As shown, a pair of protrusions 40, 40 are provided on the inner periphery of the cam inclined surface 39 and the gear climbing surface 41, through the recess 27b.

[0071] Moreover, such as Figure 3 , Figure 11 As shown, a gear descending protrusion 43 is provided on the return direction R2 side of the gear arrangement part 37 of the rotating member mounting part 25, and at a position higher than the top surface 25a of the rotating member mounting part 25. A gear abutment surface 44 is formed on the lower surface (the surface on the flange 23 side) of the gear descending protrusion 43, and the gap between the gear abutment surface 44 and the surface of the flange 23 gradually decreases as the gear abutment surface 44 faces the return direction R2 side. Furthermore, when the rising gear member 80 has climbed onto the gear climbing surface 41, when the rotating member 60 is turned towards Figure 11 When rotating in the R2 direction, the gear component 80 abuts against the gear descending protrusion 43, and then the gear component 80 descends via the gear abutment surface 44. Furthermore, as... Figure 10 As shown, before the rotating member 60 is rotated in the R1 direction, the gear contact surface 44 is opposite to the inclined surface 93 of the gear member 80 (described later), thus restricting the rotation of the rotating member 60 in the R2 direction.

[0072] Next, the shaft member 50 will be described.

[0073] The shaft member 50 has an abutment portion 54 at its top end 53, and a plurality of teeth 57 for meshing with the gear member 80 are formed axially within a predetermined range in the circumferential direction on its outer peripheral surface. More specifically, the shaft member 50 of this embodiment has a generally cylindrical shaft portion 51 extending for a predetermined length. The axial top end portion 53 of this shaft portion 51 (the end away from the fixing member 1) is generally circular. Furthermore, an abutment portion 54 made of an elastic member such as rubber is fitted to the outer periphery of this top end portion 53. The abutment portion 54 is generally cap-shaped as follows: it has a top plate at the top, a peripheral wall hanging down from the periphery of the top plate, and an opening at the bottom. It should be noted that the axial base end of the peripheral wall of the abutment portion 54 is designated as the base end portion 54a.

[0074] Furthermore, the shaft portion 51 has a pair of opposing sidewalls 51a, 51a and a pair of opposing sidewalls 51b, 51b arranged orthogonally to the pair of sidewalls 51a, 51a. The outer surfaces of the two sidewalls 51a, 51a are flat surfaces that are parallel to each other. In addition, the outer surface of each sidewall 51b is curved. The shaft portion 51 is accommodated in the base member 20 with the pair of sidewalls 51a, 51a aligned with the pair of inner surfaces 27a, 27a of the shaft receiving portion 27. As a result, the shaft member 50 is restricted from rotating relative to the base member 20.

[0075] Furthermore, on the axial base end side (the end side near the fixing member 1) of each side wall 51b of the shaft portion 51, a flexibly deformable locking claw 55 is formed via a generally "ko"-shaped slit 55a. In addition, on the outer peripheral surface of each side wall 51b of the shaft portion 51, and between the top end portion 53 and the locking claw 55, a plurality of teeth 57 extending circumferentially along the side wall 51b are formed at predetermined intervals along the axial direction of the side wall 51b, thereby providing a threaded groove portion.

[0076] These locking claws 55 and the threaded grooves formed by multiple teeth 57 are disposed within a pair of recesses 27b, 27b in the shaft receiving portion 27 when the shaft member 50 is received into the base member 20. Furthermore, as... Figure 13 As shown, by engaging a pair of locking claws 55, 55 respectively with a pair of shaft locking holes 28, 28 of the base member 20, the shaft member 50 is prevented from disengaging and is held in place of the base member 20, and the abutment portion 54 is restricted from protruding further relative to the base member 20.

[0077] Next, the rotating component 60 will be described.

[0078] like Figure 1 and Figure 5 As shown, the rotating member 60 of this embodiment has: a cylindrical wall 61, which is generally cylindrical; and a gripping portion 63, which is concentrically arranged on the outside of the base end portion 61a (near the end of the fixing member 1) of the cylindrical wall 61, and its outer periphery is circular. It should be noted that a buffer receiving portion 64 is formed between the base end portion 61a of the cylindrical wall 61 and the gripping portion 63. The buffer receiving portion 64 is a groove with a mortar-shaped inclined surface on its inner peripheral surface (see reference). Figure 1 and Figure 13 ).

[0079] The gripping part 63 serves as the portion that is gripped by the operator when the rotating member 60 is rotated. Furthermore, an annular thin-walled rib 61c is provided on the inner circumference of the top end portion 61b (the end away from the fixing member 1). The annular rib 61c is positioned above the gear member 80 housed within the rotating member 60 to prevent the gear member 80 from disengaging from the upper opening side of the rotating member 60, and to prevent the shaft member 50 from being pressed in to the maximum extent (see reference). Figure 15 and Figure 16 The annular rib 61c abuts against the top end 53 to restrict the pressing of the shaft member 50.

[0080] The inner diameter of the cylindrical wall 61 is substantially matched with the outer diameter of the rotating member mounting portion 25 of the base member 20, thereby guiding the rotational movement of the cylindrical wall 61 located outside the rotating member mounting portion 25. Furthermore, the inner diameter of the gripping portion 63 is substantially matched with the outer diameter of the flange portion 23 of the base member 20, thereby guiding the rotational movement of the gripping portion 63 located outside the flange portion 23.

[0081] Furthermore, with the rotating member 60 attached to the base member 20, the end face of the base end portion 61a of the cylindrical wall 61 is disposed facing the surface of the flange portion 23 of the base member 20 (see reference). Figure 13 As a result, the gear component 80 is prevented from disengaging from the lower opening side of the rotating component 60, and the descent movement of the gear component 80 is restricted.

[0082] Furthermore, at the base end 63a (near the end of the fixing member 1) of the gripping part 63, a plurality of slits 65a (three in this case) extending circumferentially at uniform intervals are formed along the circumference of the gripping part 63. Through these slits 65a, a flexible piece 65 capable of bending and deforming is provided at the base end 63a of the gripping part 63 (see reference). Figure 5 Furthermore, each of the flexible plates 65 has a tongue-shaped anti-detachment protrusion 67 protruding from its inner periphery toward the rotation center of the rotating member 60. Each anti-detachment protrusion 67 is engaged with the stepped portion 31 of the flange portion 23 of the base member 20 in a manner that allows it to slide into contact with the stepped portion 31 of the flange portion 23.

[0083] Furthermore, when the rotating member 60 is attached to the base member 20, with each anti-detachment protrusion 67 of the rotating member 60 aligned with each notch 35 of the base member 20, the rotating member 60 is pressed into the base member 20, causing each anti-detachment protrusion 67 to pass through the corresponding notch 35 and be positioned at the stepped portion 31 of the flange portion 23 of the base member 20. Then, by rotating the rotating member 60 in a predetermined direction relative to the base member 20, each anti-detachment protrusion 67 is locked into the stepped portion 31 of the flange portion 23. Therefore, the rotating member 60 is attached to the base member 20 in a manner that allows it to rotate relative to the base member 20 (see reference). Figure 7 ).

[0084] In this state, even if the rotating member 60 attempts to rise relative to the base member 20, the anti-detachment protrusion 67 of the rotating member 60 will lock and hang on the stepped portion 31 of the base member 20, thus preventing the rotating member 60 from rising. On the other hand, even if the rotating member 60 attempts to descend relative to the base member 20, the base end portion 61a of the cylindrical wall 61 of the rotating member 60 will abut against the surface of the flange portion 23 of the base member 20 (see reference). Figure 13 Therefore, the rotating member 60 cannot descend. Consequently, the rotating member 60 cannot move up or down relative to the base member 20.

[0085] In addition, Figure 7 In the shown state, the rotating member 60 can rotate relative to the base member 20 in the R1 direction, but its rotation relative to the base member 20 in the R2 direction is restricted. That is, even if it is desired to rotate the rotating member 60 in the R2 direction... Figure 7 When the rotating member 60 rotates in the R2 direction, the anti-detachment protrusion 67 of the rotating member 60 will also abut against the rotation restriction surface 33a, thus restricting the rotation of the rotating member 60.

[0086] On the other hand, when the rotating member 60 is directed towards Figure 7 If the R1 direction is rotated, such as Figure 8 As shown, the anti-detachment protrusion 67 can cross the protrusion 32 via the conical surface 32a, thus allowing the rotating member 60 to rotate in the R1 direction. It should be noted that when the rotating member 60 is rotated in the R1 direction, as... Figure 8 As shown, unlike the anti-detachment protrusion 67 that crosses the protrusion 32, the anti-detachment protrusion 67 crosses the top of the protrusion 34 via a conical surface 34a and abuts against another conical surface 34b. It should be noted that, from... Figure 8 When the rotating member 60 is rotated in the direction indicated by arrow R2, the anti-detachment protrusion 67 of the rotating member 60 can also cross the top of the protrusion 34 via another conical surface 34b.

[0087] In addition, such as Figure 5 , Figure 9As shown, a plurality of ribs 69, 70, and 71 are provided at a predetermined location on the inner circumference of the cylindrical wall 61 of the rotating member 60. These ribs 69, 70, and 71 protrude radially inward toward the rotating member 60 and extend axially along the rotating member 60. Figure 9 As shown, rib 69 is disposed on the outer side of one side portion 81b of the base 81 of the gear member 80. Furthermore, rib 70, with a generally L-shaped cross-section, is disposed on the outer side of the other side portion 81c of the base 81 of the gear member 80. Moreover, rib 71 is disposed on the outer side of the end face of the top portion 87a of the first protrusion 87 of the gear member 80. It should be noted that the upper ends of ribs 69, 70, and 71 are connected to the annular rib 61c, thereby improving rigidity.

[0088] These ribs 69, 70, and 71 restrict the rotation of the gear member 80 relative to the rotating member 60 and guide the gear member 80 to move in the axial direction of the rotating member 60.

[0089] In addition, such as Figure 5 As shown, a rib 73a is provided at a predetermined location on the inner circumference of the cylindrical wall 61 of the rotating member 60. The rib 73a protrudes radially inward toward the rotating member 60 and extends axially along the rotating member 60. A plate-like portion 73, wider than the rib 73a, is provided via the rib 73a. On the inner surface of the plate-like portion 73, a plurality of teeth 75 extending circumferentially (width direction) along the axial direction (height direction) of the plate-like portion 73 are formed at predetermined intervals, thus providing a threaded groove portion. It should be noted that the upper ends of the rib 73a and the plate-like portion 73 are connected to the annular rib 61c, thereby improving rigidity.

[0090] Next, the gear component 80 will be described.

[0091] The gear member 80 is constructed such that it rotates in conjunction with the rotation of the rotating member 60, and rises along with the cam mechanism, while maintaining the temporary fixed state of the shaft member 50 achieved by the temporary fixing part, and raising the shaft member 50. The gear member 80 also has a permanent fixing part 83, which restricts the lifting and lowering movement of the shaft member 50 in the raised state.

[0092] Simultaneously refer to Figure 6 In this embodiment, the gear component 80 is composed of a plate-shaped sheet that extends and bends along the inner circumference of the rotating component 60.

[0093] That is, the gear member 80 of this embodiment is composed of a plate-shaped sheet with a thickness that can be disposed in the gap between the rotating member mounting portion 25 of the base member 20 and the cylindrical wall 61 of the rotating member 60, and extends bent along the outer periphery of the rotating member mounting portion 25 and the inner periphery of the cylindrical wall 61.

[0094] More specifically, the gear member 80 has a base 81, which is a plate thickness that can be accommodated in the gear mounting portion 37 of the rotating member mounting portion 25, and is a long plate that is curved along the inner periphery of the gear mounting portion 37 and extends for a predetermined length.

[0095] Furthermore, a protrusion 81a protrudes from the inner periphery of the base 81 toward the radially inner side of the rotating member 60, which is adjacent to the gear member 80, with a specified thickness. Here, the protrusion 81a protrudes from the base 81 at a position other than the base end side (the end on the fixing member 1 side). It should be noted that one circumferential side of the base 81 (the side on the R1 direction) is designated as "one side 81b", and the other circumferential side (the side on the R2 direction) is designated as "another side 81c".

[0096] like Figure 6 As shown, a formal fixing part 83 is provided on the inner surface side of the protrusion 81a and on one side 81b of the base 81 in the circumferential direction. This formal fixing part 83 is composed of a plurality of protrusions 84, 85 extending circumferentially along the protrusion 81a and arranged axially along the protrusion 81a, and the base of the protruding strip 85 (the portion of the protruding strip 85 extending throughout the first protrusion 87 located on the inner surface of the protrusion 81a). Each protrusion 84 and protruding strip 85 forms a generally mountain-shaped extension that can engage with the teeth 57 of the shaft member 50. Furthermore, the formal fixing part 83, provided at the base 81 and the protrusion 81a, is a rigid body that will not flex or deform like the first protrusion 87, relative to its wall thickness.

[0097] Furthermore, a first protrusion 87 extends circumferentially from one side of the fixed portion 83. Here, the first protrusion 87, which is narrower than the fixed portion 83, extends from one side of the fixed portion 83 in the circumferential direction along the rotation direction R1 of the rotating member 60. A protrusion 85 for engaging with the teeth 57 of the shaft member 50 is continuously provided on both the inner surface of the first protrusion 87 and the inner surface of the fixed portion 83. It should be noted that the first protrusion 87 is narrower than the fixed portion 83, thus allowing for flexible deformation. Furthermore, the tip 87a of the first protrusion 87 in the protruding direction is slightly thicker than the rest.

[0098] Furthermore, a second protrusion 89, which is narrower than the width of the base 81, extends from one circumferential side 81b of the base 81 along the rotation direction R1 of the rotating member 60. A cam abutment 89a is provided at the top end of the second protrusion 89 in the extension direction. The cam abutment 89a extends from one axial end of the gear member 80 (the side away from the fixing member 1) toward the other axial end (the side closer to the fixing member 1) and is inclined toward the R2 direction.

[0099] Furthermore, a third protrusion 91, narrower than the width of the base 81, extends from the other circumferential side 81c of the base 81 and from the base end side of the base 81 along the return direction R2 of the rotating member 60. A tab 92 protrudes from the top end of the third protrusion 91 in the protrusion direction and from one axial end side of the gear member 80. Moreover, an inclined surface 93 is formed across the top end of the third protrusion 91 in the protrusion direction and the top surface of the tab 92 in the R2 direction. This inclined surface 93 is inclined from one axial end side of the gear member 80 toward the other axial end side and toward the R2 direction side. In addition, a guide groove 94 is formed between the other side 81c of the base 81 and the tab 92. This guide groove 94 extends along the axial direction of the gear member 80 with a certain width (see reference). Figure 10 and Figure 11 ).

[0100] And, as Figure 9 As shown, with the gear member 80 positioned inside the rotating member 60, the rib 69 of the rotating member 60 is engaged with the outer side of one side portion 81b of the base 81, the rib 70 of the rotating member 60 is engaged with the outer side of the other side portion 81c of the base 81, and the rib 71 of the rotating member 60 is engaged with the outer side of the end face of the top end portion 87a of the first protrusion 87. Furthermore, the rib 70 of the rotating member 60 is inserted into the guide groove 94 of the gear member 80.

[0101] As a result, within the rotating member 60, the movement of the gear member 80 towards the radially inward and radially outward sides of the rotating member 60 is prevented (the radially inward movement of the gear member 80 is prevented by ribs 69, 70, and 71, and the radially outward movement of the gear member 80 is prevented by the cylindrical wall 61), and the circumferential movement of the gear member 80 is prevented by ribs 69, 70, and 71. Furthermore, the lifting and lowering motion of the gear member 80 along the axial direction of the rotating member 60 is guided by ribs 69, 70, and 71. In addition, by preventing the circumferential movement of the gear member 80 by ribs 69, 70, and 71, the gear member 80 also rotates in conjunction with the rotation of the rotating member 60 (the gear member 80 rotates along with the rotating member 60).

[0102] It should be noted that when the rotating member 60 is rotated in the R1 direction, the aforementioned cam abutment portion 89a abuts against the cam inclined surface 39 of the base member 20 to raise the gear member 80. That is, as Figure 10 As shown, with the gear member 80 housed within the gear arrangement portion 37 of the rotating member mounting portion 25 of the base member 20, when the rotating member 60 is rotated in the R1 direction, the gear member 80 also rotates in conjunction with it. The cam abutment portion 89a abuts against the cam inclined surface 39 of the base member 20 and is pushed upward. Therefore, the gear member 80 rises within the rotating member 60 while being guided by the ribs 69, 70, and 71, thereby... Figure 11 As shown, it climbs up to the gear's upper climbing surface 41.

[0103] That is, the cam abutment portion 89a and the cam inclined surface 39 form the "cam mechanism" in this invention.

[0104] In addition, such as Figure 11 As shown, when the rising gear member 80 has climbed onto the gear climbing surface 41 of the base member 20, when the rotating member 60 is rotated in the R2 direction (i.e., rotated in the opposite direction to when the gear member 80 is rising), the inclined surface 93 of the gear member 80 abuts against the gear descending protrusion 43 of the base member 20. Then, a force pushing down on the inclined surface 93 from the gear abutment surface 44 of the base member 20 causes the gear member 80 to rotate and descend in the R2 direction, thus... Figure 10 As shown, the gear component 80 is housed within the gear mounting section 37, and the protrusion 92 of the gear component 80 is recessed below the gear contact surface 44. The gear component 80 then returns to its original position. Figure 10 The initial position is shown.

[0105] That is, the gear descending protrusion 43 and gear abutment surface 44 of the base component 20 and the inclined surface 93 of the gear component 80 form the "structure that causes the rising gear component to descend" in this invention.

[0106] Figure 12 The middle figure shows the relationship between the shaft member 50 and the gear member 80.

[0107] Figure 12 The image on the left and Figure 13 and Figure 14 Correspondingly, the shaft member 50 is not pressed into the base member 20. In this state, the protrusion 85 at the inner surface of the first protrusion 87 of the gear member 80 meshes with the tooth 57 on the axial base end side of the shaft member 50 (see reference). Figure 14 ), gear component 80 abuts with part 54 in Figure 12 The option furthest from the fixed member 1 is temporarily fixed to the shaft member 50 (refer to...). Figure 14 Thus, in this embodiment, the teeth 57 of the shaft member 50 and the protrusions 85 on the inner surface of the first protrusion 87 of the gear member 80 form the "temporary fixing part" in this invention.

[0108] Figure 12 The central map and Figure 15 and Figure 16 Correspondingly, in the shaft member 50 from Figure 12 The left side is pressed into the base member 20. That is, when the moving member 5 moves in a closer direction relative to the fixed member 1 (refer to...) Figure 13 , 14 The moving member 5), via the abutment portion 54, pushes the shaft member 50 in. At this time, the protrusion 85 on the inner surface of the first protrusion 87 of the gear member 80 is pressed by the teeth 57 of the shaft member 50, thereby causing the first protrusion 87 to flex and deform. The protrusion 85 and the teeth 57 engage in stages (also known as ratchet engagement), while the shaft member 50 is pressed in and lowers. That is, while maintaining the temporary fixed state between the shaft member 50 and the gear member 80 achieved by the temporary fixing portion, the shaft member 50 is pressed in and lowered. Finally, the protrusion 85 engages with the teeth 57 on the axial top side of the shaft member 50 (see reference). Figure 16 The abutment portion 54 is located close to the fixing member 1 (see reference). Figure 15 , Figure 16 ).

[0109] It should be noted that "temporarily fixing the gear component to the shaft component" in this invention means that when the abutment part is pressed with a pressure greater than a specified value, the fixed state of the shaft component and the gear component is released, the shaft component is retracted into the base component, and the height of the abutment part relative to the fixed component or the moving component becomes lower. On the other hand, when the abutment part is pressed with a pressure less than a specified value, the fixed state of the shaft component and the gear component is maintained, the shaft component is not retracted into the base component, and the height of the abutment part relative to the fixed component or the moving component is maintained.

[0110] Figure 12 The image on the right and Figure 17 and Figure 18 Correspondingly, in the position of from Figure 12 The central state causes the rotating member 60 to rotate relative to the base member 20 in the R1 direction. That is, when from the center... Figure 12 When the central state causes the rotating member 60 to rotate in the R1 direction, the gear member 80 rotates in conjunction with it in the R1 direction to raise the shaft member 50. At the same time, the fixed part 83 is fixed to the shaft member 50, restricting the lifting and lowering movement of the shaft member 50 in the raised state.

[0111] In this embodiment, when from Figure 12When the central state causes the rotating member 60 to rotate relative to the base member 20 in the R1 direction, the gear member 80, which rotates in conjunction with it, rises via the aforementioned cam mechanism. Consequently, the protrusion 85 on the inner surface of the first protrusion 87, which meshes with the teeth 57 of the shaft member 50, moves circumferentially within the threaded groove of the teeth 57, pushing against the inner surface of the teeth 57, thus causing the shaft member 50 to rise. When the rotating member 60 is further rotated in the R1 direction, the protrusion 85 on the inner surface of the fixed part 83, guided by the protrusion 85 on the inner surface of the first protrusion 87, meshes with the teeth 57 of the shaft member 50, and multiple protrusions on the inner surface of the fixed part 83 mesh with the teeth 57 of the shaft member 50 (see reference). Figure 18 The fixed part 83 moves in a manner that covers the outside of the plurality of teeth 57 (see reference). Figure 12 (The diagram on the right). The result is as follows: Figure 12 As shown in the diagram on the right, the shaft member 50 is slightly larger than... Figure 12 In the central state of rising, the lifting and lowering action of the rising shaft member 50 is restricted by the fixed part 83, and the protrusion of the abutment part 54 relative to the fixed member 1 is fixed in a way that does not change.

[0112] The shapes and structures of the base member, shaft member, rotating member, gear member, temporary fixing part, cam mechanism, lifting structure of the shaft member implemented by the gear member, permanent fixing part of the gear member, and lowering structure of the gear member that lowers the rising gear member, etc., which constitute the stopping device, are not particularly limited. In addition, in the above embodiment, the base member 20 is fixed to the fixing member 1 side, but the base member may also be fixed to the moving body side.

[0113] Furthermore, the gear member 80 in this embodiment is composed of a plate-like sheet, but it is not limited to this solution, as long as it can be configured in a rotationally restricted state inside the rotating member. In addition, in this embodiment, the temporary fixing part is composed of a plurality of teeth 57 of the shaft member 50 and a protrusion 85 of the gear member 80 (the plurality of teeth mesh with a protrusion), but for example, it is also possible to provide a plurality of teeth on both the shaft member and the gear member to make it a temporary fixing part achieved by their meshing, or to provide a concave and convex part on both the shaft member and the gear member to make it a temporary fixing part achieved by the concave and convex fitting, or to make the shaft member and the gear member a temporary fixing part achieved by friction, pressing, etc.

[0114] Furthermore, in the gear member 80 of this embodiment, the protruding portion 85 is continuously provided in a shape that extends over the inner surface of the first protruding portion 87 and the inner surface of the formal fixing portion 83. That is, it is a configuration in which one of the parts constituting the temporary fixing portion is continuously provided with the formal fixing portion. However, one of the parts constituting the temporary fixing portion and the formal fixing portion may also be provided independently without being continuously provided. Moreover, the configuration of the formal fixing portion is not limited to the protruding portion, as long as the amount, position, and height of the protrusion of the abutment portion relative to the fixing member can be fixed in a way that does not change, so that the shaft member cannot be pressed into the base member.

[0115] (Effects)

[0116] Next, the effects of the stop device 10 of the present invention, which is composed of the above-described components, will be explained.

[0117] Figure 13 and Figure 14 The diagram shows the stop device 10 assembled with the fixing member 1. Specifically, with the sealing ring 100 clamped against the back side of the flange 23 of the base member 20, the base body 21 is inserted from the surface side of the fixing hole 3 of the fixing member 1, thereby... Figure 13 , Figure 14 As shown, the sealing ring 100 abuts against the surface periphery of the fixing hole 3, and the locking step portions 29a, 29a of a pair of locking pieces 29, 29 engage with the back periphery of the fixing hole 3, thereby fixing the base member 20 to the fixing member 1.

[0118] Furthermore, in this state, the protrusion 85 at the inner surface of the first protrusion 87 of the gear member 80 meshes with the tooth 57 on the axial base end side of the shaft member 50 (see reference). Figure 14 Thus, with the abutment portion 54 protruding away from the fixing member 1 by a predetermined amount, the gear member 80 is temporarily fixed to the shaft member 50 (see reference). Figure 13 and Figure 14 ).

[0119] When the moving member 5 is moved closer to the fixed member 1 in the above state (refer to...) Figure 13 , Figure 14 As the shaft member 50 is pressed in via the abutment portion 54, the protruding portion 85 on the inner surface of the first protrusion 87 of the gear member 80 is pressed by the teeth 57 of the shaft member 50, thereby causing the first protrusion 87 to flex and deform. The protruding portion 85 engages with the teeth 57 in stages, while the shaft member 50 descends. Furthermore, the shaft member 50 is pressed in until the top end 53 of the shaft member 50 abuts against the annular rib 61c of the rotating member 60, as... Figure 15 , Figure 16As shown, the abutment portion 54 is close to the fixing member 1. Therefore, the amount of protrusion of the abutment portion 54 relative to the fixing member 1 is temporarily determined. It should be noted that when the shaft member 50 is pressed in to its maximum extent, the base end portion 54a of the abutment portion 54 is received within the buffer receiving portion 64 of the rotating member 60 (see reference). Figure 15 and Figure 16 ).

[0120] Next, after moving the movable member 5 away from the fixed member 1 to a state where the shaft member 50 is not subjected to load from the movable member 5, the rotating member 60 is rotated relative to the base member 20 in the R1 direction. Then, the gear member 80 rotates in conjunction with the rotating member 60 in the R1 direction, and the cam abutment portion 89a of the gear member 80 abuts against the cam ramp surface 39 of the base member 20. As a result, the gear member 80 is guided by ribs 69, 70, and 71 and rises within the rotating member 60. The protrusion 85 on the inner surface of the first protrusion 87 raises the shaft member 50 via the teeth 57. When the rotating member 60 is further rotated in the R1 direction, the protrusion 85 on the inner surface of the fixed portion 83 is guided by the protrusion 85 on the inner surface of the first protrusion 87 and engages with the teeth 57 of the shaft member 50. Furthermore, multiple protrusions on the inner surface of the fixed portion 83 engage with the teeth 57 of the shaft member 50 (see reference). Figure 18 Thus, while the shaft member 50 is slightly raised, the lifting and lowering action of the raised shaft member 50 is restricted by the fixed part 83. As a result, the amount of protrusion of the abutment part 54 relative to the fixed member 1 can be fixed in a way that does not change (the height of the abutment part 54 relative to the fixed member 1 can be fixed).

[0121] Furthermore, in this stop device 10, as described above, during the rotation operation of the rotating member 60, the rotating member 60 itself does not rise or fall relative to the base member 20; only the gear member 80 rises inside the rotating member 60. Therefore, during the rotation operation of the rotating member 60, no excessive force is applied to the operator, improving the operability of the rotating member 60. That is, even if the rotating member 60 is rotated in a predetermined direction by gripping the gripping part 63, the rotating member 60 will only rotate; it will not rise like the ring in the buffer device of Patent Document 1, thus preventing the application of an upward thrust caused by the rotating member 60 to the operator. As a result, the operator can rotate the rotating member 60 smoothly, improving its operability.

[0122] Furthermore, the rotating member 60 does not rise or fall relative to the base member 20; only the gear member 80 rises inside the rotating member 60 via a cam mechanism to raise the shaft member 50. Adjusting the protrusion of the abutment part 54 relative to the fixed member 1 allows the stop device 10 to be compact in the axial direction.

[0123] Furthermore, the stop device 10 has a gear member 80 that is separate from the base member 20, the shaft member 50, and the rotating member 60. A cam mechanism is provided between the gear member 80 and the base member 20. Therefore, compared with the buffer device of Patent Document 1, which has a tab on the lower end side of the ring, the rotating member 60 can be formed lower, which helps to make the stop device 10 more compact in the axial direction.

[0124] Furthermore, in commonly known screw-in rubber stoppers, the operator adjusts the protrusion of the stopper's tip relative to the fixed component by rotating the stopper. Therefore, deviations can easily occur depending on the operator, posing a problem with accuracy. Moreover, if the protrusion of the stopper's tip is insufficient, the vehicle door may sometimes be opened and closed repeatedly to adjust the protrusion, making the adjustment process cumbersome.

[0125] In this stop device 10, as described above, the gear member 80 rotates and rises in conjunction with the rotation of the rotating member 60 to raise the shaft member 50. The lifting and lowering action of the shaft member 50 is restricted by the fixed part 83, thus allowing for high-precision and accurate adjustment of the protrusion of the abutment part 54 relative to the fixed member 1. That is, when it is desired that the protrusion of the abutment part 54 relative to the fixed member 1 be the desired amount, for example, by appropriately adjusting the spacing of the teeth 57 of the shaft member 50, the rising amount of the gear member 80 implemented by the cam mechanism, etc., the protrusion of the abutment part 54 can be kept constant regardless of who rotates the rotating member 60, and the protrusion of the abutment part 54 can be adjusted with high precision.

[0126] Furthermore, after moving the movable member 5 close to the fixed member 1 and then moving the movable member 5 away from the fixed member 1, the amount of protrusion of the abutment 54 relative to the fixed member 1 can be adjusted by performing an operation such as rotating the rotating member 60 only once, so the adjustment operation can be easily performed.

[0127] Furthermore, in this embodiment, the gear member 80 is composed of a plate-like sheet that bends and extends along the inner circumference of the rotating member 60. According to this design, the gear member 80 can be arranged along the inner circumference of the rotating member 60, making it easy to reduce the outer diameter of the rotating member 60, thus making the stop device 10 radially compact.

[0128] Furthermore, in this embodiment, the gear member 80 has a first protrusion 87 extending circumferentially from one side of the fixed portion 83, and a temporary fixing portion is provided in the first protrusion 87. According to the above solution, since the temporary fixing portion is provided in the first protrusion 87 extending circumferentially from one side of the fixed portion 83, the temporary fixing portion can be easily formed.

[0129] Furthermore, in this embodiment, a plurality of teeth 57 are formed along the axial direction within a circumferentially defined range on the outer peripheral surface of the shaft member 50, and protrusions 85 for meshing with the teeth 57 of the shaft member 50 are continuously provided in such a manner that they cover the inner surface of the formal fixing portion 83 of the gear member 80 and the inner surface of the first protrusion portion 87.

[0130] According to the above scheme, since the protrusion 85 that meshes with the tooth 57 of the shaft member 50 is continuously provided in such a way that it covers the inner surface of the formal fixing part 83 and the inner surface of the first protrusion 87 of the gear member 80, it is easy to transfer from the state in which the gear member 80 is temporarily fixed to the shaft member 50 by the temporary fixing part to the state in which the shaft member 50 is restricted to rising by the formal fixing part 83.

[0131] That is, before the rotating member 60 rotates, the protrusion 85 on the inner surface of the first protrusion 87 engages with the teeth 57 of the shaft member 50, thereby maintaining the temporary fixed state of the shaft member 50 and the gear member 80. However, when the rotating member 60 is rotated in the R1 direction in this state, and the gear member 80 rotates in conjunction, the protrusion 85 on the inner surface of the first protrusion 87, which engages with the teeth 57 of the shaft member 50, rotates. The protrusion 85 on the inner surface of the fixed part 83 is guided by the protrusion 85 on the inner surface of the first protrusion 87 while engaging with the teeth 57 of the shaft member 50. As a result, the engagement state of the protrusion 85 with respect to the teeth 57 of the shaft member 50 continues uninterrupted, thereby allowing a smooth transition from the temporary fixed state of the gear member 80 with respect to the shaft member 50 to the upward restriction state of the shaft member 50.

[0132] Furthermore, in this embodiment, a structure is provided between the base member 20 and the gear member 80 to cause the rising gear member 80 to descend when the rotating member 60 rotates in the opposite direction to the rising shaft member 50 (when rotating in the R2 direction).

[0133] According to the above scheme, the gear component is lowered in a structure such that... Figure 11 As shown, the rising gear component 80 can be lowered (refer to...). Figure 10 It can readjust the amount of protrusion of the abutment part 54 relative to the fixed member 1.

[0134] (Other embodiments of the stop device)

[0135] Figures 19-22 Other embodiments of the stopping device of the present invention are shown in the figure. It should be noted that parts that are substantially the same as those in the embodiments described above are labeled with the same reference numerals and their descriptions are omitted.

[0136] In this embodiment, the main difference between the stop device and the one described above is the structure in which the gear member 80A is temporarily fixed to the shaft member 50A.

[0137] like Figure 19 and Figure 22 As shown, on the outer surfaces of a pair of flat sidewalls 51a, 51a of the shaft portion 51 of the shaft member 50A, flexible strips 52 are provided with slits 52a. The base end of each strip 52 is connected to the base end side of the shaft portion 51, and the top end of each strip 52 is connected to the back side of the top end portion 53. The slits 52a are formed on the inner side of each strip 52, thereby enabling flexible deformation. In addition, a plurality of teeth 58 are formed along the axial direction on the outer surface of each strip 52.

[0138] On the other hand, such as Figure 20 and Figure 21 As shown, the gear member 80A has a first protruding piece 87A extending from one circumferential side of the protrusion 81a. Multiple protruding ribs 85 (three protruding ribs 85 in this case) extending in a generally mountain-shaped manner are arranged axially along the inner surface of both the circumferential side of the protrusion 81a and the inner surface of the first protruding piece 87A. These multiple protruding ribs 85 form a fixed portion 83A that does not flex or deform.

[0139] Figure 22 The left-hand diagram illustrates the state where the shaft member 50 is not pressed into the base member 20. In this state, the plurality of protrusions 85 of the gear member 80A mesh with the plurality of teeth 58 on the outer surface of the strip 52 of the shaft member 50A, and the gear member 80A is temporarily fixed to the shaft member 50A with the abutment portion 54 furthest away from the fixing member 1. That is, in this embodiment, the plurality of teeth 58 of the shaft member 50A and the plurality of protrusions 85 of the gear member 80A form the "temporary fixing portion" in this invention.

[0140] Furthermore, when the moving member 5 moves closer to the fixed member 1, the shaft member 50A is pressed in via the abutment portion 54. Thus, as... Figure 22 As shown in the central figure, multiple teeth 58 of the shaft member 50A are pressed by multiple protrusions 85 of the gear member 80A, thereby causing the strip 52 to flex and deform. The multiple protrusions 85 and the multiple teeth 58 engage in stages. At the same time, the shaft member 50A is pressed in and lowered, and the abutment portion 54 is located close to the fixing member 1.

[0141] Subsequently, when the rotating member 60 is rotated in the R1 direction, the gear member 80A rotates in conjunction with it in the R1 direction to raise the shaft member 50A. At the same time, the fixed part 83A is fixed to the shaft member 50A, restricting the lifting and lowering movement of the shaft member 50A in the raised state (see reference). Figure 22 (The image on the right).

[0142] In this embodiment, the same effect as in the above embodiment can be achieved.

[0143] (Another embodiment of the stop device)

[0144] Figures 23-33 Another embodiment of the stopping device of the present invention is shown in the figure. It should be noted that parts that are substantially the same as those in the above embodiment are labeled with the same reference numerals and their descriptions are omitted.

[0145] In this embodiment of the stopping device, the main difference is that the structure in which the gear member 80B is temporarily fixed to the shaft member 50 is different from that in the above embodiment.

[0146] like Figure 24 As shown, the formal fixing part 83 in the gear component 80B of this embodiment is composed of a protruding strip 85 and a protruding part 84 arranged along the axial direction of the protrusion 81a. Specifically, the formal fixing part 83 is composed of a protruding strip 85 provided on the axial top end side of the protrusion 81a (a position away from the second extension 89), a protruding strip 85 provided on the axial base end side of the protrusion 81a (a position close to the second extension 89), and a protruding part 84 disposed between these protruding strips 85, 85.

[0147] Furthermore, in this embodiment, the temporary fixing part has a first temporary fixing part and a second temporary fixing part, and the temporary fixing force of the shaft member 50 and the gear member 80B implemented by the second temporary fixing part is configured to be greater than the temporary fixing force of the shaft member 50 and the gear member 80B implemented by the first temporary fixing part.

[0148] It should be noted that the "temporary fixing force of the shaft member and gear member" in this invention refers to the following force: when a pressing force less than a specified value is applied to the abutment part, the fixed state of the shaft member and gear member can be maintained to maintain the height of the abutment part relative to the fixed member or the moving member; and when a pressing force greater than a specified value is applied to the abutment part, the fixed state of the shaft member and gear member is released, thereby reducing the height of the abutment part relative to the fixed member or the moving member (i.e., a force that can resist a pressing force less than a specified value but cannot resist a pressing force greater than a specified value).

[0149] Furthermore, in this embodiment, the stop device is configured such that: a portion of the gear member 80B forming a formal fixing portion 83 is disposed on the base end side in the rotation direction R1 when the rotating member 60 is rotated to raise the gear member 80B via the cam mechanism; a portion of the gear member 80B forming a first temporary fixing portion is disposed on the top end side in the rotation direction R1; and a portion of the gear member 80B forming a second temporary fixing portion is disposed between the portion forming the first temporary fixing portion and the portion forming the formal fixing portion 83.

[0150] The structure of the temporary fixing part will be described in detail below. Figure 23 and Figure 24 As shown, the gear member 80B of this embodiment has two protrusions 87 and 95 extending from one side (the side in the R1 direction) of the portion forming the permanent fixing portion 83 in the rotational direction R1. Here, the fourth protrusion 95 forms "one protrusion" in this invention, and the first protrusion 87 forms "another protrusion" in this invention. Furthermore, a protrusion 85 that forms a second temporary fixing portion is provided at the base end side of the first protrusion 87, which is the other protrusion, in the rotational direction R1, and a protrusion 85 that forms a first temporary fixing portion is provided at the top end side of the first protrusion 87, which is the other protrusion, compared to the fourth protrusion 95, which is the first protrusion. In addition, the first protrusion 87, which is the other protrusion, extends longer than the fourth protrusion 95, which is the first protrusion.

[0151] Specifically, it includes: a first protrusion 87 extending from one circumferential side of the fixed portion 83 and the axial top end side of the protrusion 81a along the rotation direction R1 of the rotating member 60; and a fourth protrusion 95 extending from one circumferential side of the fixed portion 83 and the axial base end side of the protrusion 81a along the rotation direction R1 of the rotating member 60. Furthermore, protrusions 85, 85 constituting the fixed portion 83, extend continuously along the circumferential direction on the inner surface of each protrusion 87, 95.

[0152] Furthermore, the protruding strip 85 on the inner surface of the base end side in the rotational direction R1 of the first protrusion 87 and the protruding strip 85 on the inner surface of the fourth protrusion 95 are "parts of the second temporary fixing part for forming the gear component" in this invention. Figure 23 (The part indicated by reference numeral K2 in the attached drawing). Furthermore, the protruding portion 85, located on the top end side of the first protrusion 87 in the rotational direction R1, specifically on the inner surface side of the portion of the first protrusion 87 located on the top end side in the rotational direction R1 closer to the fourth protrusion 95, is, in this invention, the "part of forming the first temporary fixing part of the gear member" ( Figure 23 (The part indicated by reference numeral K1 in the attached figure).

[0153] It should be noted that the "first temporary fixing part" in this invention is composed of the portion of the gear member that forms the first temporary fixing part and the teeth 57 of the shaft member 50. Furthermore, the "second temporary fixing part" in this invention is composed of the portion of the gear member that forms the second temporary fixing part and the teeth 57 of the shaft member 50.

[0154] Furthermore, in this embodiment, as described above, the temporary fixing force between the shaft member 50 and the gear member 80B achieved by the second temporary fixing part is configured to be greater than the temporary fixing force between the shaft member 50 and the gear member 80B achieved by the first temporary fixing part. However, if this is to be explained in detail, it will be as follows: Figure 25As shown, the protrusion 85 on the inner surface of the top side of the first protrusion 87 in the rotational direction R1 engages with the tooth 57 of the shaft member 50, forming a temporary fixed state between the shaft member 50 and the gear member 80B achieved by the first temporary fixing part. Figure 25 In the state shown, the gear member 80B is disposed on the surface of the flange portion 23 of the base member 20.

[0155] When from Figure 25 The temporary fixed state of the shaft member 50 and gear member 80B, achieved by the first temporary fixing part, is such that when the gear member 80B is rotated in the R1 direction by the rotating member 60 (not shown), as... Figure 27 As shown, the protrusion 85 on the inner surface of the base end side of the first protrusion 87 in the rotational direction R1 engages with the tooth 57 of the shaft member 50, and the protrusion 85 on the inner surface of the fourth protrusion 95 also engages with the tooth 57 of the shaft member 50. This state forms a temporary fixed state between the shaft member 50 and the gear member 80B, achieved by the second temporary fixing part. Figure 27 In the state shown, the second protrusion 89 of the gear member 80B is in contact with the top 39a of the cam ramp 39 of the base member 20.

[0156] In addition, when from Figure 27 The temporary fixing state of the shaft member 50 and gear member 80B, achieved by the second temporary fixing part, causes the gear member 80B to rotate in the R1 direction, as shown. Figure 29 As shown, the fixed part 83 engages with the tooth 57 of the shaft member 50, thereby permanently fixing the shaft member 50 and the gear member 80B. Figure 29 In the state shown, the second protrusion 89 of the gear member 80B climbs up to the gear climbing surface 41 of the base member 20.

[0157] It should be noted that, regarding the above... Figure 25 The state shown Figure 27 The state shown Figure 29 The state shown is locked by the relationship between the anti-detachment protrusion 67 of the rotating member 60 and the protrusions 34A, 34B, 34C, and 34D provided on the back side of the flange portion 23 of the base member 20. (The rotating member 60 is restricted from rotating relative to the base member 20).

[0158] That is, such as Figure 26 As shown, in this embodiment, a protrusion 34A is provided on the back side of the flange portion 23 of the base member 20, near the other sidewall 21b of the base body 21. A conical surface 34a is formed on one side of the protrusion 34A, and a rotation-limiting surface 34c, which is perpendicular to the surface direction of the flange portion 23, is formed on the other side. Furthermore, as... Figure 28 and Figure 30As shown, a pair of protrusions 34B and 34C arranged adjacent to each other in the circumferential direction are provided on the back side of the flange portion 23 and near a side wall 21b of the base body 21, and a protrusion 34D arranged separately from the protrusion 34C in the circumferential direction. Conical surfaces are formed on both sides of each protrusion 34B, 34C, and 34D.

[0159] Furthermore, in Figure 25 As shown, in the temporary fixed state of the shaft member 50 and gear member 80B, where the protrusion 85 on the inner surface of the top side in the rotational direction R1 of the first protrusion 87 engages with the tooth 57 of the shaft member 50, and the first temporary fixing part achieves this, such as... Figure 26 As shown, the rotating member 60 can rotate relative to the base member 20 in the R1 direction, but its rotation relative to the base member 20 in the R2 direction is restricted. That is, even if it is desired to rotate the rotating member 60 in the R2 direction... Figure 7 When rotating in the R2 direction, the anti-detachment protrusion 67 of the rotating member 60 will also abut against the rotation restriction surface 34c of the protrusion 34A, so the rotating member 60 is restricted from rotating relative to the base member 20.

[0160] In addition, Figure 27 In the temporary fixed state of the shaft member 50 and gear member 80B achieved by the second temporary fixing part, the protrusion 85 on the inner surface of the base end side in the rotation direction R1 of the first protrusion 87 engages with the tooth 57 of the shaft member 50, and the protrusion 85 on the inner surface of the fourth protrusion 95 engages with the tooth 57 of the shaft member 50. Figure 28 As shown, the designated anti-detachment protrusion 67 of the rotating member 60 is disposed between a pair of protrusions 34B and 34C. Therefore, for the rotating member 60, as long as the rotating member 60 is not rotated in the R1 or R2 direction by a rotational force exceeding a specified value so as to cross the conical surface of the protrusions 34B and 34C, the rotating member 60 is restricted from rotating relative to the base member 20.

[0161] Moreover, in Figure 29 As shown, in the state where the fixed part 83 engages with the teeth 57 of the shaft member 50, thereby fixing the shaft member 50 and the gear member 80B, as Figure 30 As shown, the designated anti-detachment protrusion 67 of the rotating member 60 is positioned adjacent to a conical surface 34a of the protrusion 34D. Therefore, as long as the designated anti-detachment protrusion 67 does not cross the conical surface 34a of the protrusion 34D in the R2 direction, the rotating member 60 is restricted from rotating relative to the base member 20 in the R2 direction. On the other hand, regarding rotation in the R1 direction, as... Figure 29 As shown, the gear contact surface 41a of the base member 20 abuts against the cam contact portion 89a of the second protrusion 89 of the gear member 80B, thereby restricting the rotation of the rotating member 60 relative to the base member 20.

[0162] It should be noted that in this embodiment, the protrusions 85 and 85 on the inner surfaces of the two protrusions 87 and 95 extending from one circumferential side of the formal fixing part 83 constitute the part forming the first temporary fixing part and the part forming the second temporary fixing part. However, the part forming the first temporary fixing part and the part forming the second temporary fixing part are not limited to this scheme. For example, it is also possible to (1) provide three or more protrusions from one side of the formal fixing part and set the protrusions on their inner surfaces as the part forming the first temporary fixing part and the second temporary fixing part; or (2) provide one protrusion from one side of the formal fixing part, set the top part in the extension direction (the top part in the rotation direction R1) to be narrow so that the top part in the extension direction is set as the part forming the first temporary fixing part, and set the middle part in the extension direction to be wide so that the middle part in the extension direction is set as the part forming the second temporary fixing part.

[0163] Figure 31 and Figure 32 The diagram shows a modified example of a gear component.

[0164] The gear component 80C is constructed as follows: a connecting wall portion 97 extends from one side of the fixed portion 83 and between the first protrusion 87 and the fourth protrusion 95, and the first protrusion 87 and the fourth protrusion 95 are connected to the connecting wall portion 97. Furthermore, no protruding strip 85 provided on the inner surface of the protrusions 87 and 95 protrudes from the inner surface of the connecting wall portion 97, and the connecting wall portion 97 is thinner than the protrusions 87 and 95.

[0165] ( Figures 23-33 (An example of the usage method of the illustrated implementation)

[0166] Next, refer to Figure 33 An example of how to use the stop device of this embodiment will be described.

[0167] In this case, the fixed component 1 is the body frame of a box-type multi-purpose vehicle, hatchback, etc., and the movable component 5 is the so-called rear door.

[0168] First, with the movable member 5 open relative to the opening of the vehicle frame, which is the fixed member 1, the movable member 5 is held in place by a jig before painting (step S1).

[0169] Next, the stop device is assembled around the opening of the fixed member 1, and the gear member 80B is rotated by the rotating member 60, which is set as follows: Figure 27 The temporary fixing state of the shaft member 50 and the gear member 80B achieved by the second temporary fixing part is shown (step S2).

[0170] Next, the opening of the movable member 5 relative to the fixed member 1 is closed (step S3). At this time, the shaft member 50 and the gear member 80B are temporarily fixed by the second temporary fixing part. This temporary fixing force is greater than the temporary fixing force of the shaft member 50 and the gear member 80B implemented by the first temporary fixing part. Therefore, even if the pressing force from the movable member 5 is applied to the shaft member 50, the shaft member 50 will not fall. Therefore, the opening of the movable member 5 relative to the fixed member 1 is not completely closed, and the movable member 5 is held in a state that is slightly suspended relative to the opening of the fixed member 1 (a gap is generated between the opening of the fixed member 1 and the movable member 5).

[0171] Then, using the gap between the opening of the fixed component 1 and the moving component 5, various components such as the latch and the weatherstripping are assembled onto the moving component 5, and components such as the gas support rod are assembled between the fixed component 1 and the moving component 5 (step S4).

[0172] Then, the gear component 80B is rotated in the R2 direction by rotating component 60, denoted as... Figure 25 The diagram shows the temporary fixing state of the shaft member 50 and the gear member 80B achieved by the first temporary fixing part. Next, the moving member 5 is pressed into the fixing member 1, thereby causing the protrusion 85 of the first extension 87 of the first temporary fixing part to engage in stages with the teeth 57 of the shaft member 50, and the shaft member 50 descends. Then, the surface of the moving member 5 is aligned with the surface periphery of the opening of the fixing member 1, thereby adjusting the protrusion of the abutment 54 relative to the fixing member 1 (step S5).

[0173] Next, the opening of the moving member 5 relative to the fixed member 1 is opened, and the gear member 80B is rotated in the R1 direction by the rotating member 60, as follows. Figure 29 As shown, the shaft member 50 and the gear member 80B are formally fixed by engaging the fixed part 83 with the tooth 57 of the shaft member 50. As a result, the lifting and lowering movement of the shaft member 50 is restricted, and the protrusion of the abutment part 54 relative to the fixed member 1 is fixed (step S6).

[0174] ( Figures 23-33 (Effects of the illustrated implementation method)

[0175] Next, the effects of the stop device constructed as described above will be explained.

[0176] That is, in this embodiment, the temporary fixing part has a first temporary fixing part and a second temporary fixing part, and the temporary fixing force of the shaft member 50 and the gear member 80B implemented by the second temporary fixing part is configured to be greater than the temporary fixing force of the shaft member 50 and the gear member 80B implemented by the first temporary fixing part.

[0177] Therefore, in the state where the gear component 80B is temporarily fixed to the shaft component 50 by the second temporary fixing part (refer to...) Figure 27 Under these conditions, the gear component 80B is temporarily fixed to the shaft component 50 by the first temporary fixing part (refer to...). Figure 25 Compared to the previous method, this method can improve the temporary fixing force of the shaft component 50 and the gear component 80B.

[0178] The result is, such as Figure 33 As shown in step S3, when the moving member 5 moves closer to the fixed member 1, it is possible to prevent the moving member 5 from abutting against the fixed member 1 (here, it is possible to prevent the periphery of the moving member 5 from abutting against the periphery of the opening of the fixed member 1), thereby creating a gap between the fixed member 1 and the moving member 5.

[0179] Therefore, as Figure 33 As shown in step S4, various components such as latches and weatherstrippings can be assembled onto the movable component 5 using the gap between the fixed component 1 and the movable component 5, and components such as gas support rods can be assembled between the fixed component 1 and the movable component 5, thereby improving the assembly workability of components such as latches.

[0180] It should be noted that when the movable component 5 is moved closer to the fixed component 1 as described above, if the movable component 5 abuts against the fixed component 1, the process of moving the movable component 5 away from the fixed component 1 when assembling various components such as the latch will become complicated.

[0181] Furthermore, in this embodiment, the stop device is configured such that: a portion forming a permanent fixing part 83 of the gear member 80B is disposed on the base end side in the rotation direction R1 when the rotating member 60 is rotated to raise the gear member 80B via the cam mechanism, and a portion forming a first temporary fixing part of the gear member 80B is disposed on the top end side in the rotation direction R1. Figure 23 The portion forming the second temporary fixing part (as shown in K1) has a gear member 80B disposed between the portion forming the first temporary fixing part and the portion forming the permanent fixing part 83. Figure 23 (The part shown in K2).

[0182] According to the above scheme, due to the structure described above, when the gear member 80B is rotated in the R1 direction by the rotating member 60, firstly, the gear member 80B is temporarily fixed to the shaft member 50 by the first temporary fixing part (see reference). Figure 25 Then, by further rotating the gear component 80B in the R1 direction, the gear component 80B is temporarily fixed to the shaft component 50 by the second temporary fixing part (see reference). Figure 27 ).

[0183] As a result, when the gear component 80B is temporarily fixed to the shaft component 50 by the second temporary fixing part, the assembly workability of various components such as the locking buckle between the moving component 5, the fixing component 1 and the moving component 5 can be improved, and when the gear component 80B is temporarily fixed to the shaft component 50 by the first temporary fixing part, the protrusion of the abutment part 54 relative to the fixing component 1 can be adjusted.

[0184] Furthermore, in this embodiment, the portion forming the first temporary fixing part, the portion forming the second temporary fixing part, and the permanent fixing part 83 in the gear member 80B are arranged sequentially along the rotation direction (R1 direction) when the gear member 80B is permanently fixed, so the operator can easily perform the operation intuitively.

[0185] Moreover, such as Figure 23 and Figure 24 As shown, in this embodiment, the gear member 80B has two protrusions 87 and 95 extending from one side of the circumferential direction of the fixed part 83 in the rotational direction R1. One protrusion (fourth protrusion 95) is provided with a protruding part 85 that forms part of the second temporary fixed part, and the other protrusion (first protrusion 87) is provided with a protruding part 85 that forms part of the first temporary fixed part on the top side of the first protrusion (fourth protrusion 95). The other protrusion (first protrusion 87) extends longer than the first protrusion (fourth protrusion 95).

[0186] According to the above scheme, due to the aforementioned structure, it is easy to establish a difference between the temporary fixing force of the shaft member 50 and gear member 80B achieved by the first temporary fixing part and the temporary fixing force of the shaft member 50 and gear member 80B achieved by the second temporary fixing part. That is, since the fourth protrusion 95, which is one protrusion, is shorter than the first protrusion 87, it is less prone to deformation than the first protrusion 87, making it easier to increase the temporary fixing force achieved by the second temporary fixing part compared to the temporary fixing force achieved by the first temporary fixing part. As a result, it is easy to achieve a structure in which the temporary fixing force of the shaft member 50 and gear member 80B achieved by the second temporary fixing part is greater than the temporary fixing force achieved by the first temporary fixing part.

[0187] In addition, in such Figure 31 and Figure 32As shown in the gear member 80C, the first protrusion 87 and the fourth protrusion 95 are connected to the connecting wall 97 in a structure that increases the rigidity of the portion of the two protrusions 87 and 95 connected by the connecting wall 97, making them less prone to flexing and deformation. As a result, the temporary fixing force of the gear member 80C relative to the shaft member 50, achieved by the second temporary fixing part, can be further increased.

[0188] It should be noted that the present invention is not limited to the above-described embodiments, and various modified embodiments can be adopted within the scope of the present invention, and such embodiments are also included within the scope of the present invention.
