Description

Technical Field

[0001] The present disclosure relates to an automatic rotation mechanism, a side collision protection device including the automatic rotation mechanism, and a child seat including the side collision protection device.

Background Art

[0002] A child seat is a device attached to an automobile seat. In the case of emergency braking or unexpected collision of an automobile, the safety seat reduces the impact on a child, restricts the body movement of the child, thereby reducing the damage suffered by the child in an accident and ensuring the safety of the child during travel.

[0003] Some safety seats provide a side collision protection device to reduce side collisions received by the seat. The side collision protection device is a side wrap extending from two outer sides of the seat and has a folded position and a deployed position. In the folded position, the side collision protection device is attached to the outside of the seat, reducing the occupied space, and in the deployed position, the side collision protection device protrudes outward from the side of the seat, providing a buffer between the seat and the automobile.

[0004] In some uses of a child seat, the seat can rotate back and forth with respect to the base. When the seat rotates, the protruding side collision protection block may interfere with the top rod installed on the base, making it impossible to directly rotate the seat forward or backward. Before rotating the seat, it is necessary to manually fold the side collision protection block, which affects the convenience of use.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Therefore, an automatic rotation mechanism needs to be designed for the side impact protection block. When rotating forward or backward relative to the base, the automatic folding structure automatically blocks the side impact. The bag can be folded. [Means for solving the problem]

[0006] The automatic rotation mechanism of this application comprises a protective block body (first object) and a sheet (second object) The automatic rotation mechanism controls the relative movement with respect to the object, and includes a locking mechanism and a drive mechanism. The locking mechanism is located on the first object and the relative movement Between the locked position to prevent movement and the unlocked position to allow the relative movement It can be switched, and the drive mechanism is located in the second object, and the lock The locking mechanism can be operated to switch from the locked position to the unlocked position. The aforementioned operating mechanism is positioned on a rotating sheet (third object), and the rotating sheet is base The drive mechanism can be operated when moving toward the fourth object. .

[0007] Due to the advantages of the automatic rotation mechanism of this invention, the relative motion between the protective block body and the sheet is rotational. It can be automatically unlocked based on the relative movement between the rotating seats, This enables coordination between multiple objects, reducing the number of operations required from the user and improving usability. The experience can be improved.

[0008] In one embodiment, the protective block body is positioned in an unfolded position and a folded position relative to the sheet. It can rotate between the position and the position, and when the protective block body is in the deployed position, the The locking mechanism switches to the locked position so that the protective block body is held in the deployed position. The replaceable and foldable elastic member is between the protective block body and the sheet. The foldable elastic member is positioned at the pivot joint between the protective blocks. The main body is biased to the aforementioned folded position.

[0009] The protective block body is held in the deployed position and folded by a foldable elastic member. It is biased to the folded position. Therefore, when the position lock of the protective block body is released, The protective block itself automatically moves to its folded position.

[0010] In one embodiment, when the protective block body is in the folded position, the drive mechanism The locking mechanism is held in the unlocked position.

[0011] When the protective block body is in the folded position, the locking mechanism is in the unfolded position. It does not prevent the user from moving the protective block body to its deployed position. If you need to lock it, you only need to operate the protective block itself, and the locking mechanism will not be locked at the same time. No operation is required.

[0012] In one embodiment, the locking mechanism includes a locking pin, a slot portion, and a locking elastic member. The lock pin is slidably positioned on the protective block body, and the seal It can slide between an extended position that engages with the toe and a contracted position that detaches from the sheet. The slot portion is positioned on the seat and is open toward the lock pin. The locking pin has a slot, and when it is in the extended position, at least a portion of it is Inserted into the lock slot, the lock elastic member is disposed between the lock pin and the protection block and the main body, and biases the lock pin to the extended position.

[0013] An operable locking relationship between the protection block main body and the seat is realized by the mechanism of the locking mechanism.

[0014] In one embodiment, the locking mechanism further includes a release member, and the release member is connected to the lock pin and can be operated from outside the protection block main body to switch the lock pin between the extended position and the retracted position.

[0015] The user can directly release the lock of the protection block main body by operating the release member without releasing the lock between the rotating seat and the base. Therefore, the user provides another operation method for releasing the lock of the protection block main body.

[0016] In one embodiment, the drive mechanism includes a cam and a traction member. The cam is rotatably disposed on the sheet, can abut against the lock pin, and the cam includes a drive portion and an avoidance portion provided adjacent to each other along the circumference. The cam can rotate so that the drive portion abuts against the lock pin, thereby driving the lock pin to slide to the retracted position, or the avoidance portion can rotate so as to correspond to the lock pin, thereby permitting the lock pin to slide to the extended position. The traction member is connected between the cam and the operating mechanism, and the operating mechanism is The cam is rotated via the traction member so that the drive unit contacts the lock pin. It operates in a way that allows it to move.

[0017] By providing a cam, the lock pin extends to a different position in response to the pulling motion of the traction member. It can move between the contracted position and the other position.

[0018] In one embodiment, the drive mechanism further includes a cam elastic member, and the cam elastic member is , positioned between the cam and the seat, with the avoidance portion facing the lock pin This provides a force to drive and rotate the cam.

[0019] The cam elastic member is used for resetting the cam. The cam is pulled by the traction member. If not, the cam will automatically reset and move the lock pin to the extended position. can.

[0020] In one embodiment, the operating mechanism includes a locking member, and the locking member is the traction part It is connected to the material and includes the first end of the locking member and the second end of the locking member. The first end of the locking member abuts against the base, and the second end of the locking member is movable toward the rotating seat. The locking member 1 is connected to the rotating seat and the base, and when the rotating seat and the base move relative to each other, the locking member 1 The end of the locking member detaches from the base, and the second end of the locking member slides in the tensile direction, causing the tension to be pulled away. Pull the puller.

[0021] The locking member converts the relative motion between the base and the rotating seat into the pulling action of the traction member. To fulfill one's role.

[0022] In one embodiment, the operating mechanism includes an elastic member of the operating mechanism, and the elastic member of the operating mechanism is , positioned between the rotating seat and the locking member, the second end of the locking member is connected to the tension To bias in the opposite direction.

[0023] The elastic member of the operating mechanism is used to reset the locking member.

[0024] In one embodiment, the locking member is a locking lever, and the first tip of the locking member is The first end of the lock lever, and the second end of the lock member, are the second end of the lock lever. The second end of the lock lever is connected to the traction member, and the base is the rotating seat The lock lever has a limited slot opening in the seat, and the lock lever has the first end of the lock lever The rotating sheet is directed in the tensile direction toward the base so that it contacts within the limited slot. It extends diagonally to the and when the rotating sheet and the base move relative to each other, the lock The first end of the lever rotates toward the rotating seat from the limited slot, and the operating mechanism It further includes an auxiliary rod, the auxiliary rod comprising a first end and a second end. The first end of the auxiliary rod is between the first end of the lock lever and the second end of the lock lever. The second end of the auxiliary rod is rotatably connected to the auxiliary rod joint of the lock lever, and the second end of the auxiliary rod is rotatably connected to the auxiliary rod joint of the lock lever. It is rotatably connected to the rotating sheet.

[0025] The auxiliary rod defines the direction of movement of the lock lever, thereby controlling the limit of the throttle. It rotates from the lock lever, not only around the second end while rotating from the lock, but also simultaneously pulls. To pull the components.

[0026] In one embodiment, the second end of the auxiliary rod is subjected to the tension of the second end of the lock lever. It is located in the direction opposite to the direction, and the first end (321) of the auxiliary rod is an abbreviation of the lock lever. It is connected in the middle position.

[0027] By positioning the auxiliary rod as described above, the lock lever can be operated without generating significant resistance. It can effectively restrict movement.

[0028] In one embodiment, the first end of the locking lever is a triangle that protrudes toward the base. The two slopes of the triangle each form two guide slopes, and the limited slot Each of the sections has a portion corresponding to the two guide slopes, and the rotating sheet is the base When the two guide slopes move relative to the lock lever in different directions, the lock lever The end of 1 rotates toward the rotating sheet away from the limited slot It is separated from the set.

[0029] According to the structure of the first end of the locking lever and the limited slot described above, the base is relative to the rotating seat. When rotated clockwise or counterclockwise, the operating mechanism can move in the same way.

[0030] In one embodiment, the locking member is a locking slider, and the first end of the locking member The first end of the slider is the first end of the locking member, and the second end of the slider is the second end of the locking member, and the front The base is provided with a limited slot opened in the rotating seat, and the lock slider is, Located within the slider slot of the rotating seat, and adjacent to or separated from the base, the slider It can be moved, and when the rotating seat and the base move relative to each other, the limited seat The rod pushes the first end of the slider, causing the lock slider to move away from the base. The lock slider slides in such a way, and the lock slider is opposed to the sliding direction of the lock slider. The towing head of the towing member is provided with an operating slot that extends diagonally, and the operating slot It is slidably inserted into and the lock slider slides away from the base. When this happens, the lock slider pulls the traction member.

[0031] The lock slider provides an alternative method for implementing the locking member between the base and the rotating seat. The traction member can also be pulled in accordance with the relative motion between them.

[0032] In one embodiment, the rotating seat is provided with guide slots, and the guide slots are It is positioned vertically below the aforementioned rock slider, extending in the tensile direction, and the traction head is also in front of it. It is slidably inserted into the guide slot and restricted to sliding in the tensile direction. It can be done.

[0033] Guide slots can restrict the direction of movement of the towing head, thereby controlling the towing head This allows you to avoid unexpected movements from the enemy.

[0034] In one embodiment, the foldable elastic member is a torsion spring.

[0035] The aforementioned torsion spring can simply provide a folding force to a foldable member.

[0036] In one embodiment, the drive unit has an arcuate surface that protrudes outward relative to the pivot of the cam. The avoidance portion has an arcuate surface that is recessed inward relative to the pivot of the cam.

[0037] The cam shape described above is advantageous for the smooth movement of the lock pin.

[0038] The side impact protection device of this disclosure includes the automatic rotation mechanism described above and a protective block body. .

[0039] Therefore, this application enables the automatic folding function of the side collision protection blocks. do.

[0040] The child seat of this invention comprises a base, a rotating seat, a seat, and the above-mentioned side impact protection. The device includes the rotating sheet, which is rotatably positioned on the base, and the sheet The side impact protection block of the side impact protection device is placed on the rotating sheet. The buckle is positioned on one or both sides of the sheet.

[0045] This specification describes the present invention with reference to specific embodiments, but the present invention is described in detail in the illustrations. It should not be limited. Specifically, without departing from the present invention, the scope of the claims may be limited. These details can be modified in various ways within reasonable limits.

[0046] The explanations of directions such as "front," "back," "up," and "down" described here are for your understanding. This is solely for the purpose of making things easier. The present invention is not limited to the relevant directions, It can be adjusted according to the actual situation. This application is a typical embodiment. While references are provided for explanation, the terminology used is illustrative and not limiting.

[0047] Referring to Figures 1 to 5, we will outline the child seat 1 according to this application.

[0048] Child seat 1 consists of a base 500, a rotating seat 700, a seat 600, and side panels. Includes collision protection device 400. Base 500 is a car seat 1. This is for attaching to carrier seats 600 such as to. The rotating seat 700 is for use with The axis 710 is rotatably positioned above the base 500 and is substantially perpendicular to the base 500. It is rotatable around the center, and the seat 600 can be in a forward position (shown in Figures 1 to 3) and a rearward position ( It is possible to switch between (not shown) the sheet 600 and the rotating sheet 700. It is kicked and rotates relative to the base 500 together with the rotating sheet 700. In some applications The sheet 600 can be fixed to the rotating sheet 700, and for other applications, the sheet 60 To enable the pitch adjustment function, the seat 600 slides back and forth relative to the base 500. It can be id or oscillating. This invention is suitable for these two applications. Side impact protection The locks 400 are positioned one or two on each side of the seat 600, It may extend laterally from the side of 600.

[0049] The rear of the base 500 is designed to rest against the backrest of a car seat, ensuring the safety of child seat 1. To improve quality, a top rod 540 extending almost vertically upward is provided. (Figure 4) As shown, when the sheet 600 and the rotating sheet 700 rotate relative to the base 500, the side When the front impact protection block 400 is in the deployed position, the side impact protection block 400 is... The prod 540 obstructs the rotation of the sheet 600 and the rotating sheet 700 into place. It may become impossible.

[0050] The child seat 1 according to this application is equipped with an automatic rotation mechanism, and the seat 600 and rotation When the seat 700 rotates relative to the base 500, the side impact protection block 400 The seat 600 automatically rotates from the unfolded position to the folded position. In this way, interference and collision between the side impact protection block 400 and the top rod 640 are prevented. This can be successfully avoided, and damage to child seat 1 can be prevented. At the same time, manually fold the side impact protection block 400 and then rotate the seat 600. As there is no need to do so, as shown in Figure 5, the convenience of using and operating the child seat 1 is greatly improved. It will improve in width.

[0051] As shown in Figures 6 to 12, the automatic rotation mechanism according to the present invention comprises a locking mechanism 100 and a drive mechanism. It includes mechanism 200 and operating mechanism 300. The locking mechanism 100 is a side impact protection block 4 It is positioned at 00 and prevents relative movement of the side collision protection block 400 relative to the seat 600. It is possible to switch between a locked position and an unlocked position that allows this relative movement. The drive mechanism 200 is located on the seat 600 and locks the locking mechanism 100 from the locked position. It is operable to switch to the release position. The operating mechanism 300 is located on the rotating seat 700. The rotating sheet 700 (and the sheet 600 as well) is positioned relative to the base 500. When moving, the drive mechanism 200 is activated, thereby locking the drive mechanism 200. Unlock 100 locks.

[0052] The side impact protection block 400 is connected to the housing 410 and retains, as shown in Figures 8 to 11. Includes the protective block body 420. The housing 410 is attached to the side of the sheet 600. It is formed as part of sheet 600. Housing 410 is protective block It has a storage space 411 for housing the main body 420.

[0053] The protective block body 420 is positioned between the unfolded position and the folded position, and the housing 410 (and The sheet 600 is also rotatable relative to the same position. The protective block body 420 is in the deployed position. At some point, the locking mechanism 100 is used to maintain the protective block body 420 in the deployed position. It can be switched to the locked position. Between the protective block body 420 and the sheet 600 A foldable elastic member, such as a torsion spring, is positioned at the pivot joint. The pivot spring biases the protective block body 420 to the folded position. A force is constantly applied to the body 420 to fold it inward. Also, the protective block body 420 When in the folded position, the drive mechanism 200 holds the locking mechanism 100 in the unlocked position. do.

[0054] Therefore, as shown in Figures 8 and 9, when the protective block body 420 is in the deployed position The locking mechanism 100 locks the protective block body 420 in the deployed position. (As shown in Figure 10) As shown above, when the rotating sheet 700 (and sheet 600) rotates relative to the base 500... The drive mechanism 200 drives the operating mechanism 300, which in turn drives the locking mechanism 100, and As a result, the locking mechanism 100 will no longer lock the protective block body 420 in the deployed position. At that time, the protective block body 420 is biased to the folded position by a torsion spring and automatically folds. Folding is achieved. When it is necessary to unfold the protective block body 420, the locking mechanism 1 00 does not lock the protective block body 420 in the folded position, therefore the protective block body 4 The 20 can be manually pulled to the deployed position.

[0055] Referring again to Figures 6 through 11, the locking mechanism 100 and the drive mechanism 200 according to the present application I will explain.

[0056] The locking mechanism 100 consists of a locking pin 120, a slot portion 110, and a locking elastic member 130. It may include, and further include, a release member 140.

[0057] The locking pin 120 is slidably positioned within the protective block body 420, and sheet 6 It is slidable between an extended position in which it engages with 00 and a retracted position in which it detaches from the sheet 600. More specifically, the lock pin 120 has a substantially cylindrical shape. In the extended position, The locking pin 120 extends at least partially from the protective block body 420.

[0058] As shown in Figure 6, the slot portion 110 is on the seat 600 (in other words, the housing 4 It is positioned at the top of the 10 and has a lock slot 111 that opens toward the lock pin 120. The lock pin 120, when in its extended position, is at least partially engaged with the lock slot 11. It is inserted into 1. The slot portion 110 may also be formed as part of the side surface of the sheet 600. The extending direction of the lock slot 111 faces the protective block body 420 in the deployed position. Therefore, when the protective block body 420 rotates to the deployed position, the lock pin 1 This allows 20 to be inserted into the lock slot 111, thereby the protective block body 420 is designed to rotate and then lock. The cam 210 of the drive mechanism 200 is This effectively prevents the lock pin 120 from entering the slot portion 110, however This will be explained in more detail later.

[0059] Referring to Figure 8, the locking elastic member 130 is connected to the locking pin 120 and the protective block body 4 It is positioned between 20 and biases the lock pin 120 to its extended position. Thus, the protective block When the main body 420 rotates to the deployed position, the lock pin 120 moves the protective block body 420 itself It locks dynamically. In this embodiment, the locking elastic member 130 has one end connected to the locking pin 12 It may be a spring with a sleeve at one end of 0, and the other end of the spring is the protective block body 420 It is connected internally.

[0060] Also, referring to Figure 8, the release member 140 is such that the protective block body 420 faces outward or inward. It is positioned on the surface facing the wedge 410 and connected to the lock pin 120. Release member 140 is pressed from the outside of the protective block body 420 and slides, locking the lock Switching n120 between an extended position and a retracted position relative to the protective block body 420. This is possible. Therefore, the user can use the release member 140 (not the operating mechanism 300) By directly manipulating the lock pin 120, the rotation of the protective block body 420 relative to the sheet 600 The action can be deactivated.

[0061] As shown in Figures 7 to 11, the drive mechanism 200 includes a cam 210 and a traction member 220. It may also include a cam elastic member 214.

[0062] The cam 210 is rotatably positioned on the seat 600 and can contact the lock pin 120. It is possible. The cam 210 has a drive unit 211 and an avoidance unit 212 that are arranged adjacent to each other in the circumferential direction. The drive unit 211 has an arcuate surface that protrudes outward relative to the pivot 215 of the cam 210. Furthermore, the avoidance portion 212 has an arcuate surface that is recessed inward relative to the pivot 215 of the cam 210. When the protective block body 420 is in the deployed position, the cam 210 is locked when the drive unit 211 is locked. It rotates so as to contact pin 120, thereby sliding lock pin 120 into the retracted position. It can be driven to cause (as shown in Figure 9), or the avoidance unit 212 locks into place. It is pivoted to face the pin 120, thereby sliding the lock pin 120 to its extended position. Allow it to do so (as shown in Figure 8). The protective block body 420 is folded to the folded position. At some point, the cam 210 is affected by the biasing force of the lock elastic member 130 that biases the lock pin 120. By resisting, the lock pin 120 is held in the retracted position.

[0063] More specifically, the cam 210 is positioned within the cam slot 112 of the slot section 110. The axial direction of the cam 210 is substantially perpendicular to the sliding direction of the lock pin 120. Therefore, the cam slot 112 and the lock slot 111 are substantially perpendicular, that is, Therefore, the cam slot 112 is substantially parallel to the radial direction of the cam 210, and the lock slot The pivot 111 is substantially parallel to the axial direction of the cam 210 or to the pivot 215. Drive unit 2 11 is spaced approximately 90 degrees circumferentially from the avoidance section 212, and this circumferential distance can be adjusted according to the actual situation. For example, it is also possible to set the value to be greater or less within a range of 30 degrees to 150 degrees.

[0064] The cable slot 213 is located on the outer circumference of the cam 210 in order to allow the traction member 220 to pass through. It is open. The cable slot 213 is at least partially along the outer circumference of the cam 210. A cable 221 is provided which extends along the outer circumference of the cam 210 and engages with the cam 210. It is designed to be internal.

[0065] The traction member 220 is connected between the cam 210 and the operating mechanism 300, and the operating mechanism 3 00 is such that the drive unit 211 contacts the lock pin 120, and the traction member 220 is used to The Mu210 can be operated to rotate.

[0066] As shown in Figure 7, the cam elastic member 214 is positioned between the cam 210 and the seat 600. The avoidance section 212 is then biased to rotate the cam 210 so that it faces the lock pin 120. Therefore, when the operating mechanism 300 does not drive the drive mechanism 200, the avoidance portion of the cam 210 212 always faces the lock pin 120, and the lock pin 120 slides into its locked position. Allow it to do so.

[0067] Referring to Figures 12 to 16, the operating mechanism 300 according to the first embodiment of the present application will be described. To clarify, the operating mechanism 300 of the first embodiment includes a locking member (in this embodiment, a locking lever) -310) and the operating mechanism elastic member 330 are included, and an auxiliary rod 320 may also be included.

[0068] The lock lever 310 has a first end 311 and a second end 312. The first end 311 of the locking lever abuts against the base 500. The second end of the locking lever End 312 is a rotating sheet 700 (specifically, a chute 7 provided on the rotating sheet 700) 30) is rotatably and slidably connected and connected to the traction member 220. (See Figure 15) As shown, when the rotating seat 700 moves relative to the base 500, the lock lever - The first end 311 is detached from the base 500, and the second end 312 of the locking lever is in the tensile direction. Slide to position 314 and pull the towing member 220.

[0069] The traction member 220 is slidable within the cable sheath 222. The cable sheath 222 includes a cable 221 positioned on the cable sheath 222, with one end of the cable sheath 222 being a rotating sheet 70. One end is connected to the cable sheath fixing part 720, and the other end is connected to the housing of the protective block body 420. It is connected to part 410 (not shown). Cable 221 has one end attached to the second locking lever. It is connected to end 312 and the other end is connected to cam 210 (see Figures 8 to 11). Therefore Then, when the second end 312 of the locking lever pulls the cable 221, the cable 221 moves to In response, the cam 210 is pulled, causing the cam 210 to come into contact with the lock pin 120. It will rotate in the direction of the cable sheath 222, protective block body 42 Since the extension length of the cable 221 between 0 and the rotating sheet 700 is specified, sheet 600 When (the same applies to the side impact protection block 400) moves relative to the rotating seat 700 The tension in cable 221 remains unchanged.

[0070] As shown in Figures 14 and 15, the first end 311 of the locking lever is located on the rotating seat 700. When rotating relative to the base 500 (i.e., when the rotating seat 700 is in a forward position or When the lock lever is in the rear position, the first end 311 of the lock lever receives a force that causes it to contact the base 500. This force pushes the second end 312 of the lock lever in the tensile direction 314, causing it to slide. It is arranged to be converted to [this].

[0071] The operating mechanism elastic member 330 is positioned between the rotating seat 700 and the locking lever 310. The second end 312 of the lock lever is biased in the direction opposite to the tensile direction 314. Specifically, One end of the operating mechanism elastic member 330 is connected to a fixing pin or fixing lug (not shown) of the rotating seat 700. The other end of the operating mechanism elastic member 330 is connected to the lock lever 310. The second end 312 is connected to the lock lever, which follows the second end 312 into the chute 730. It slides. Therefore, there is no relative rotation between the rotating sheet 700 and the base 500. (That is, when the rotating seat 700 is positioned between the forward and backward positions), The elastic member of the moving mechanism resets the second end 312 of the lock lever, and at the same time resets the first end of the lock lever. Reset terminal 311.

[0072] More specifically, the base 500 has a limited slot 51 opened in the rotating seat 700. A 0 is provided. The lock lever 310 has a limited slot at the first end 311 of the lock lever. The rotating sheet 700 is positioned relative to the tensile direction 314 so that it can come into contact with the 510. It extends diagonally toward the base 500. The rotating seat 700 and the base 500 are relative to each other. When moved, the first end 311 of the lock lever moves toward the limited slot towards the rotating seat 700. It rotates from 510.

[0073] The base 500 can be provided with multiple limited slots 510 along the direction of rotation. For example, two limited slots 510 can be provided at 180-degree intervals. When the rotating seat 700 (and the seat 600 as well) rotates to the forward or backward position The first end 311 of the lock lever can be brought into contact with different limited slots 510. In this manner, when the rotating seat 700 is in the forward or backward position, the operating mechanism 300 Since the drive mechanism 200 cannot be operated, the lock pin 120 inside the cam 210 The lock could not be released, and as a result, the protective block body 420 was held in the deployed position. It can be done.

[0074] The first end 311 of the lock lever was triangular in shape, protruding toward the base 500. Alternatively, the two inclined surfaces of the triangle each form two guide slopes 311a. The fixed slot 510 has portions corresponding to the two guide slopes 311a, respectively. Figure 1 As shown in 5, when the rotating sheet 700 moves in a different direction relative to the base 500, 2 The two guide slopes 311a are spaced nearly apart from the limited slot 510, thereby locking the lever The first end 311 rotates from the limited slot 510 towards the rotating seat 700.

[0075] The auxiliary rod 320 includes an auxiliary rod first end 321 and an auxiliary rod second end 322. End 321 locks between the first end 311 and the second end 312 of the lock lever. The auxiliary rod joint 313 of the Clever 310 is rotatably connected. Second end 32 of the auxiliary rod 2 is rotatably connected to the rotating seat 700. More specifically, the second end of the auxiliary rod 322 is positioned relative to the second end 312 of the lock lever in the opposite direction to the tensile direction 314. It is positioned. In this embodiment, the auxiliary rod joint 313 is substantially in the middle of the lock lever 310. It is positioned in the middle.

[0076] As shown in Figures 14 and 15, the rotating sheet 700 rotates relative to the base 500. When turned, the first end 311 of the lock lever is pushed by the limited slot 510, and this As a result, the first end 311 of the lock lever swings toward the rotating seat 700. Due to the presence of the auxiliary rod 320, the swing of the first end 311 of the lock lever is controlled by the lock lever Slide the second end 312 in the tensile direction 314. This locks the second end 31 of the lever. When the first end 311 of the lock lever is swung while 2 is not slid, the auxiliary rod 32 It becomes necessary to compress the zeros, but the auxiliary rod 320 is incompressible. Therefore, As the first end 311 of the lever swings, the second end 312 of the lock lever moves in the tensile direction 314 Slide toward it.

[0077] Figures 12 to 16 show the rotating sheet 700 rotating counterclockwise relative to the base 500. This illustrates the case where the rotating sheet 700 rotates clockwise relative to the base 500. However, please understand that the operation method for the operating mechanism 300 is the same.

[0078] Referring to Figures 18 to 29, the operating mechanism 300 according to the second embodiment of the present application will be described. I will reveal it.

[0079] Similar to the first embodiment, the base 500 of the second embodiment also has an opening for the rotating seat 700. A limited slot 510 is provided, and the form of the limited slot 510 in the second embodiment The shape can be the same as in the first embodiment, so in the description of the second embodiment, the base The explanations for slots 500 and 510 are omitted.

[0080] The operating mechanism 300 of the second embodiment includes a locking member (in this embodiment, a lock slider 3) 50) and a slider elastic member 360 are included.

[0081] The rotating seat 700 extends radially (in this embodiment, laterally) and is connected to the base 500. A slider slot 740 that opens towards the front is provided. The lock slider 350 is It is located within the slider slot 740 and is slidable to move closer to or further away from the base 500. There is. The first end 351 of the lock slider 350 is located within the slider slot 740. The second end of the slider 352, opposite to the first end 351 of the slider, is located at the base 500. It is facing. The lock slider 350 extends from the slider slot 740, and the slider The second end 352 can be brought into contact with the limited slot 510 of the base 500. (As shown in Figures 18 to 23).

[0082] The second end 352 of the slider has a triangular or other shape that matches the limiting slot 510. Therefore, when the rotating sheet 700 and the base 500 move relative to each other, The fixed slot 510 pushes the first end 311 of the slider, thereby locking the slider 350 It slides away from the base 500 and retracts into the slider slot 740 (Figure 2) (As shown in Figure 29 from 4).

[0083] The Rock Slider 350 has a section that extends diagonally to the sliding direction of the Rock Slider 350. An operating slot 353 is provided. The towing head 223 of the towing member 220 operates It is slidably inserted into the 353, thereby allowing the lock slider 350 to be inserted into the base 50 The traction member 220 is pulled when sliding away from 0. More specifically, the operating slot 353 moves forward in the tensile direction (longitudinal direction in this embodiment). On the side, it is close to the base 500, and on the rear side in the tensile direction, it moves away from the base 500.

[0084] The rotating seat 700 also includes guide slots 750 (shown in Figures 22 and 23). It is also possible. The guide slot 750 is positioned vertically below the lock slider 350 and pull It may extend in the tension direction. The traction head 223 also slides into the guide slot 750. It is inserted so as to slide in the tensile direction by the guide slot 750. It is restricted. More specifically, the lock slider 350 is restricted in the direction away from the base 500. When ridden, the towing head 223 slides under the pull of the operating slot 353. Initially, the traction head 223 is limited by the guide slot 750, The traction head 223 can only slide in the direction of the guide slot 750.

[0085] The slider elastic member 360 is connected to the second end 352 of the slider of the lock slider 350. Positioned between the Daslot 740 and the Rock Slider 350, with the Rock Slider 350 attached towards the Base 500. To exert force. More specifically, the end of the slider slot 740, which is away from the base 500, A slider elastic member biasing section 741 may be provided, and the slider elastic member biasing section 741 is based It may be formed to be recessed from the end of the slider slot 740, which is away from 500. The Ida elastic member 360 may be a compression spring, and one end of it may be a slider elastic member biasing portion 741 It abuts against the first end, and the other end abuts against the second end 352 of the slider.
