Description

  The present invention relates to an operation knob mounting structure in which an operation knob is detachably attached to an arm member.

  The operation member that is swung by manual operation has an arm member and an operation knob provided at the tip of the arm member, and the arm member is swung by manually operating the operation knob. The operation member is used in various fields. For example, in vehicles, especially automobiles, it is used for opening / closing doors, bonnets, trunk lids, etc., and for unlocking operation of a lock mechanism for locking a folding roof member in an open car in a stored state. Yes.

  Although the arm member and the operation knob are integrally formed, it is often desired to form the operation knob separately from the arm member. For example, when an operation knob is positioned in a vehicle interior for a vehicle, the operation knob is formed to be quite large from the viewpoint of operability and is required to have a good appearance. On the other hand, the arm member is exclusively functional. A surface is required, and the maximum width is required to be as small as possible so that it can pass through a small opening formed in the trim material or the like because of its extension to the outside of the vehicle interior. For this reason, the arm member and the operation knob are formed separately and are later integrated by screwing or bonding.

By the way, since an operation knob that is manually operated is easily damaged and may be damaged, it may be required to replace only the operation knob. In addition, the trim material is removed and various maintenance (for example, replacement of the speaker covered with the trim material or replacement due to breakage of the folding roof member) is performed, but the operation knob is obstructed when the trim material is removed. Therefore, it is desirable to make the operation knob removable from the arm member. When the arm member and the operation knob are integrated by bonding, it is substantially difficult to replace the operation knob, and when it is screwed, both the installation work and the replacement work are extremely troublesome. Patent Document 1 discloses a structure in which an arm member and an operation knob are integrated by a fitting type, and prevention of disengagement is performed with a check claw. The device disclosed in Patent Document 1 is not particularly intended for removal of the operation knob, and even if the operation knob is easily attached, it is practically difficult to remove the operation knob.

Will be done. Further, by elastically deforming the release lever portion in the direction in which the release lever portion comes close, the engagement of the locking claw portion with respect to the locking recess is released, and the operation knob can be easily detached from the arm member. In addition to the above, since the storage recess is formed on the operation knob, it is preferable to make the maximum width near the tip of the arm member as small as possible compared to the case where the storage recess is formed on the arm member side. Especially, for example, it is preferable to make the opening for penetrating the arm member formed in the vehicle interior wall material as small as possible.

Further, a pair of release lever portions are formed so as to be substantially parallel, and the pair of left and right release lever portions are elastically deformed in a direction in which the tip portions of the pair of release lever portions are brought close to each other. In this case, by providing a pair of the locking recess and the locking claw portion, the operation knob of the operation knob is provided. While securing the attachment to the arm member more securely, the pair of release levers can be elastically deformed and released by simply pinching the tip of the pair of release levers with the fingers of one hand. Therefore, the operation knob can be removed very easily.

According to the first aspect of the present invention, the operation knob can be easily attached to and detached from the arm member. Further, this is preferable in setting the maximum width near the tip of the arm member to be as small as possible.

  Hereinafter, embodiments of the present invention will be described. In the embodiment, in an open car, an operation knob is detachably attached to an arm member having a lock mechanism that locks a folding roof member in a retracted state. The case is shown. Based on the above premise, the lock mechanism portion will be described first, and then the details of the structure in which the operation knob is detachably attached to the arm member will be described.

  In FIG. 1, a vehicle S that is an open car is a two-theta type having a driver's seat 2 and a passenger seat 3 in a passenger compartment 1, and a trunk room 4 is located immediately behind the driver's seat 2 and the passenger seat 3. A vehicle compartment rear wall 5 serving as a partition wall is disposed. In FIG. 1, the folding roof member 6 is folded and stored in the vicinity of the upper end of the vehicle rear wall 5, and the upper and rear sides of the vehicle compartment 1 are opened. It is in a state. As shown in FIG. 2, the upper and rear sides of the passenger compartment 1 are covered with the roof member 6 by lifting the front end of the roof member 6 in the stored state and moving it forward from this open state. The closed state is set (the usage state of the roof member 6). In the embodiment, the roof member 6 is a so-called soft-top type in which a hood member is assembled to a frame material and is foldable. However, the roof member 6 is a hard-top type that is foldable by combining a plurality of hard panel materials. May be.

  A locking device R for locking the roof member 6 in the stored state is provided near the upper end of the vehicle interior rear wall 5. The outline of the locking device R will be described with reference to FIGS. First, the locking device R roughly includes a main body member 10, a locking member 20, and an operation member 30, and also includes a return spring 40 and a pin member 41 for oscillating shaft configuration. The main body member 10 is formed of a hard synthetic resin, and is fixed to the vehicle body by a fixture 43 using a plurality of mounting holes 11 formed in the bottom wall portion thereof. More specifically, the main body member 10 extends in the vehicle width direction as a whole, and is seated on the upper surface of the cross member 9 as a strength member constituting the upper end portion of the vehicle interior rear wall portion 5. It is fixed to the cross member 9.

  The main body member 10 has a cylindrical storage portion 12 that extends in the front-rear direction and is opened rearward, and the locking member 20 is stored and held in the storage portion 12 so as to be slidable in the front-rear direction. ing. The locking member 20 can take a lock position that protrudes rearward from the main body member 10 and an unlock position that retreats from the lock position toward the main body member 10. The locking member 20 is positioned above the hook member 7 fixed to the distal end portion of the roof member 6 in the housed state when in the locked position. Thereby, the upward displacement of the hook member 7 is restricted, and the roof member 6 is brought into a locked state in which it is held in the housed state. When the locking member 20 is in the unlocked position, the upward displacement restriction of the hook member 7 by the locking member 20 is released, and the roof member 6 is operated toward the use state shown in FIG. It becomes possible. Such a locking member 20 is always urged toward the lock position by a return spring 40 disposed in the back of the storage portion 12.

  The operation member 30 is held with respect to the upper end portion of the main body member 10 so as to be swingable about a swing axis α extending in the vehicle width direction using a pin member 41. The operation member 30 includes an intermediate connecting portion 31 extending in the vehicle width direction, and a pair of protruding portions 32 that protrude short upward and rearward at each longitudinal end of the intermediate connecting portion 31. In a substantially middle portion of the main body member 10, the pin member 41 is used so as to be swingable. An engaging portion 33 that extends downward is extended from the tip of each protrusion 32. A long arm portion 34 extends from one end of the intermediate connecting portion 31. The arm portion 34 passes through the trim member 8 that covers the rear wall portion 5 of the vehicle compartment, and the tip portion thereof extends into the vehicle compartment 1. An operation portion that is manually operated is provided at the tip portion of the arm portion 34. 35 is provided. The arm portion 34 corresponds to an arm member, and the operation portion 35 corresponds to an operation knob.

  The engaging portion 33 of the operating member 30 is set so as to act on the locking member 20 as will be described later, and the operating member 35 is lifted substantially upward to swing the operating member 30. The locking member 20 in the locked position is pressed forward by the engaging portion 33 and moved toward the unlocked position against the urging force of the return spring 40. When the upward lifting force on the operation unit 35 is released, the return spring 40 returns the locking member 20 to the locked position.

  The locking member 20 is shown in FIGS. Hereinafter, the details of the locking member 20 will be described with reference to FIGS. 3 and 4 showing the overall relationship and FIGS. 11 to 15 showing the main body member 10. First, the locking member 20 has a shape extending in the front-rear direction, and as a whole is an integrally molded product of hard synthetic resin. The locking member 20 has an upper surface at its rear end portion that is an inclined surface 21 that gradually goes downward as it goes rearward, and a lower surface at the rear end portion that is a substantially horizontal flat surface 22. Guide protrusions 23 and 24 extending in the front-rear direction are formed on each side surface of the locking member 20 so as to be spaced apart in the vertical direction. Further, on each side surface of the front end portion of the locking member 20, a protrusion 25 is formed between the upper and lower guide protrusions 23 and 24 and is set short in the front-rear direction.

  A pair of upper and lower guide grooves 13, 14 extending in the front-rear direction is formed on the inner surface of the storage portion 12 formed in the main body member 10 so as to correspond to the pair of upper and lower guide protrusions 23, 24 of the locking member 20. Is formed. A recess 15 extending in the front-rear direction is formed on the inner surface of the storage portion 12 between the pair of upper and lower guide grooves 13 and 14 so as to correspond to the protrusion 25 of the locking member 20. The guide protrusions 23 and 24 of the locking member 20 are slidably fitted in the guide grooves 13 or 14 of the storage portion 12, and the protrusion 25 of the locking member 20 is slidable in the recess 15 of the storage portion 12. Mated. An example of setting the shape of the fitting portion between the guide protrusions 23 and 24 and the guide grooves 13 and 14 is shown in FIG. The locking member 20 is smoothly slid with respect to the storage portion 12 by the guide function using such protrusions (protrusions) and grooves (recesses). A return spring 40 including a coil spring is disposed in the storage portion 12 so as to be positioned between the front end surface of the locking member 20 and the front end surface (back wall surface) of the storage portion 12. A protruding portion 26 is formed on the front end surface of the locking member 20 so that the rear end portion of the return spring 40 is fitted without rattling.

  A through hole 27 penetrating in the vertical direction is formed from the middle part in the front-rear direction of the locking member 20 to the rear end part, and the rear wall part of the through hole 27 serves as an engagement surface 27a. An opening 10 a is formed in the upper wall portion of the main body member 10 so as to correspond to the position of the through hole 27. The aforementioned engaging portion 33 of the operation member 30 extends into the through hole 27 through the opening 10a and faces the engaging surface 27a so as to be able to contact from the rear. That is, by disengaging the engaging portion 33 of the operation member 30 forward, the locking member 20 is displaced toward the unlock position.

  The operation member 30 is shown in FIGS. Hereinafter, the details of the operation member 30 will be described with reference to FIGS. 3 and 4 showing the overall relationship and FIGS. 11 to 14 showing the main body member 10. First, each of the pair of protrusions 32 described above of the operation member 30 is formed with a mounting hole 36 at a substantially intermediate portion thereof. In order to hold the operation member 30 in a swingable manner, the main body member 10 is formed with four support portions 16a to 16d projecting upward on the upper wall portion thereof in series in the vehicle width direction. A mounting hole 17 is formed in each of the support portions 16a to 16d. With one projection 32 of the operating member 30 positioned between one adjacent support 16a and 16b and the other projection 32 positioned between the other adjacent support 16c and 16d , By allowing the pin member 41 to pass through the mounting holes 17 and 36, the operation member 30 is swingably held with respect to the main body member 10 (one pin member 41 is not shown in FIG. 4). ).

  In the embodiment, the arm portion 34 of the operation member 30 has a bifurcated shape, and extends from the end of the intermediate coupling portion 31 opposite to the side where the locking member 20 is located. The arm portion 34 extends substantially downward, more specifically, slightly forward as it goes downward, and is bent toward the front in the vicinity of the lower end of the body member 10. Are formed in a substantially J-shape. As is clear from FIG. 3, the body member 10 is also covered from above by the trim material 8 that covers the rear wall portion 5 of the passenger compartment, but the lower portion of the arm portion 34 is covered by the trim material 8. , Only the front end of the bent portion is set so as to pass through the trim member 8 and be positioned in the vehicle compartment 1. The operation unit 35 attached to the distal end portion of the arm unit 34 is positioned immediately before the trim material 8.

  The operation unit 35 is positioned near the upper end of the passenger compartment rear wall 5, but is positioned between the driver seat 2 and the passenger seat 3 in the vehicle width direction as shown in FIG. The front surface of the operation portion 35, that is, the surface facing the inside of the passenger compartment 1 is set so as to extend substantially in the vertical direction, more specifically along the direction in which the trim material 8 extends. 8 are arranged so as to constitute a part. The trim member 8 is formed with a concave portion 37 into which a finger F can be inserted below the operation portion 35. The operation member 30 is an integrally molded product except for the operation portion 35, and the operation portion 35 is fixed to the distal end portion of the arm portion 34 by an appropriate technique such as press fitting or screwing. In addition, a protrusion 35a that slightly protrudes downward is formed at the front end of the operation unit 35 so that the finger F can be easily caught. In other words, the lower surface of the operation portion 35 is set in a shape that becomes concave upward by forming the protruding portion 35a.

  The length (arm length) from the swing axis α to the operation portion 35 (particularly, the protruding portion 35a serving as the hook portion of the finger F) is the contact portion between the engagement portion 33 and the engagement surface 27a from the swing axis α. The length is sufficiently longer (about 3 times in the embodiment). Thus, the swinging external force applied to the operation portion 35 is boosted and transmitted to the engaging portion 33 (the lever principle). The operation member 30 is an integrally molded product made of hard synthetic resin except for the operation portion 35, and the operation portion 35 is also made of hard synthetic resin.

  Here, the main body member 10 is provided with a locking projection 18 projecting forward from the bottom wall at a position in the vehicle width direction corresponding to the arm 34. The upper surface of the locking projection 18 constitutes a receiving surface in the scope of claims, and is positioned directly below the arm portion 34 in the locked position shown in FIG. Has been. The locking projection 18 has a sufficient bending strength, and a projection 18a is formed further upward from the upper surface thereof. A flat plate made of an elastic member such as rubber is formed on the upper surface of the projection 18a. The cushion material 19 is fixed. In the locked position, the arm portion 34 is in a positional relationship such that it does not abut against the locking projection 18 but slightly abuts against the cushion material 19. When the arm portion 34 is swung further in the locking direction than the lock position, the cushion material 19 is crushed and deformed, and the arm portion 34 is brought into contact with the locking projection 18 and further swung. The movement is regulated.

  3 and 18 in which the locking member 20 is in the locked position, the operating portion 35 is lifted substantially upward by the finger F, so that the engaging portion 33 of the operating member 30 causes the engaging surface of the locking member 20 to move. The locking member 20 is moved to the unlocked position against the urging force of the return spring 40, and the lock on the hook member 7 is released. Thereby, the roof member 6 can be moved (deployed) to the use position shown in FIG. When the unlocking operation is performed, the occupant seated in the driver's seat 2 or the passenger seat 3 extends the arm backward with the palm facing upward, and hooks the finger F on the protruding portion 35a of the operating portion 35. In this state, it will be lifted upwards and will be forced into a rather tight posture. However, due to the boosting action of the lever principle, the lifting force of the operating portion 35 is small to unlock, and it is also easy to exert upward force rather than pulling forward. It can be unlocked. In addition, the hooking action using the protrusion 35a allows the finger F to be effectively unlocked without slipping from the operation portion 35, and the unlocking operation can be performed more easily. In addition to the above, the upward displacement of the operating portion 35 in the unlocking direction coincides with the initial direction of movement when the folded roof member 6 is moved to the use position. This is also preferable in order to make the occupant definitely recognize it.

  When the roof member 6 is put into use, the locking member 20 is returned to the locked position by the return spring 40. Therefore, the next time the roof member 6 is housed and locked, the hook member 7 is displaced downward to the position shown in FIG. 3 and FIG. 18. The hook member 7 that is pressed downward displaces the locking member 20 toward the unlocked position along the inclined surface 21 of the locking member 20, and locks in a state where the locking member 20 is in the unlocked position. The locking member 20 is returned to the locked position by the return spring 40 immediately after the position lower than the member 20 (the locked state shown in FIGS. 3 and 18 is obtained). Of course, since the lower surface of the locking member 20 is a substantially horizontal flat surface 22, the hook member 7 is surely positioned below the locking member 20 to ensure a reliable locked state.

  When the locking member 20 returns from the unlocked position to the locked position, the operating member 30 swings so that the operating portion 35 is directed downward, that is, the direction in which the arm portion 34 abuts the locking projection 18. However, the cushion material 19 is used for buffering. When the occupant receives a large force that inadvertently presses the operating portion 35 backward, the cushion material 19 is crushed and deformed, and the arm portion 34 abuts against the locking projection 18, and the occupant A large pressing force is received by the locking projection 18 which is excellent in strength, and the arm portion 34 is prevented from being broken.

  By forming the arm portion 34 in a substantially J shape, the arm portion 34 protrudes toward the vehicle compartment 1 as compared with a case where the arm portion 34 is linearly connected from the swing axis α of the operation member 30 to the operation portion 35. The amount can be reduced, which is preferable in securing sufficient space in the minute passenger compartment 1. The locking device R is prepared as a set assembly in which the locking member 20, the operation member 30, the return spring 40, and the like are previously assembled with the main body member 10, and fixes the main body member 10 to the vehicle body. As a result, the mounting state shown in FIG. 3 can be obtained, and can be easily retrofitted in the vehicle assembly process.

  As shown in FIGS. 18 and 19, it is preferable to provide a cushion material 44 made of an elastic member such as rubber at the rear end of the upper wall portion of the storage portion 12 of the main body member 10 (cushion material). 44 is not shown in FIG. That is, when the folded roof member 6 is put into the housed state, the cushion member 44 prevents the front end portion of the roof member 6 from coming into direct contact with the main body member 10 to prevent buffering and noise generation. Is preferable.

  Next, with reference to FIGS. 20 to 29, a structure in which an operation portion 35 as an operation knob is detachably attached to an arm portion 34 as an arm member will be described.

  First, as shown in FIGS. 20 to 22, a housing recess 50 is formed on the back side of the operation unit 35 (the back side when viewed from the passenger compartment side). A plurality of (two in the embodiment) guide protrusions 51 and 52 are formed on the left and right wall surfaces of the inner surface of the storage recess 50 so as to extend obliquely upward. That is, a pair of left and right guide protrusions 51 are formed (see also FIG. 23), and a pair of left and right guide protrusions 52 (see also FIG. 24) are formed in parallel with the guide protrusion 51. . A pair of left and right inner wall portions 57 are formed on the inner surface of the operation portion 35 slightly apart from the pair of left and right outer wall surfaces, and the guide protrusions 51 and 52 are formed on the inner surface side of the inner wall portion 57. The protrusion is formed so that the problem of sink marks at the time of molding does not occur on the outer surface side of the operation portion 35 that is required to have an appearance. The inner wall portion 57 and the outer wall surface of the operation portion 35 are connected by a plurality of rib portions 58 so that the strength of the inner wall portion 57 is sufficiently secured.

  A fitting projection 60 is formed at the distal end of the arm 34 so as to correspond to the storage recess 50. The fitting protrusions 60 are positioned in the storage recess 50, and a plurality of (two in the embodiment) linearly extend respectively on the left and right wall surfaces of the outer surface of the fitting protrusion 60. Guide grooves 61 and 62 are formed. That is, a pair of left and right guide groove portions 61 are formed (see also FIG. 26), and a pair of left and right guide groove portions 62 (see also FIG. 27) are formed in parallel to the guide groove portion 61. .

  The opening width of the guide groove portions 61 and 62 is set to be slightly larger than the thickness of the guide protrusion portions 51 and 52 so that the guide protrusion portions 51 and 52 can slide smoothly without rattling. However, the leading end portions of the guide groove portions 61 and 62 are guide portions (guide surfaces) 63 whose opening width gradually increases toward the leading end, and the opening width at the leading end of the guide portion 63 is as follows. The thickness of the guide protrusions 51 and 52 is made sufficiently larger. The guide action of the guide part 63 absorbs a slight misalignment between the guide protrusions 51 and 52 and the guide groove parts 61 and 62, in particular, a position shift in the thickness direction of the guide protrusions 51 and 52. The guide protrusions 51 and 52 can be smoothly fitted into the guide grooves 61 and 62.

  The fitting protrusion 60 is inserted into the storage recess 50 to a predetermined depth while the guide protrusion 51 is fitted in the guide groove 61 and the guide protrusion 52 is fitted in the guide groove 62. As a result, the operating portion 35 is set to a predetermined mounting position with respect to the arm portion 34. As a restricting means for restricting the operation portion 35 from being disengaged from the arm portion 34 at a predetermined mounting position, a locking recess and a locking claw portion are formed. That is, in the embodiment, a pair of left and right engaging recesses 55 is formed by cutting out part of the inner surface side of the pair of left and right guide protrusions 51 (see FIG. 23). The other guide protrusion 52 is not formed with a locking recess 55 (see FIG. 24).

  Corresponding to the locking recess 55, the fitting protrusion 60 is formed with a pair of left and right locking claws 65 (see FIGS. 25 and 26). In the embodiment, a pair of left and right release lever portions 70 extending in the extending direction of the guide groove portion 61 are formed on the fitting projection portion 60, and a locking claw portion 65 is formed on the outer surface of the release lever portion 70. (See FIGS. 20, 25, and 26).

  In order to attach the operation portion 35 to the arm portion 34, the guide groove portion 61 is slidably fitted to the guide projection portion 51, and the guide groove portion 62 is slidably fitted to the guide projection portion 52. What is necessary is just to insert the protrusion part 60 deeply in the storage recessed part 50 to the predetermined depth. At the time of this fitting, the fitting is performed smoothly by the guide action of the guide portion 63. When the fitting proceeds to a predetermined depth, the locking claw portion 65 is engaged with the locking recess 55, and the attachment is completed. That is, when the locking claw portion 65 is engaged with the locking recess 55, the operation portion 35 is prevented from coming off from the arm portion 34 (see FIG. 28). Note that the locking claw portion 65 is pressed by the guide projection 51 before the engagement with the locking recess 55, and the distal end portions of the pair of left and right release lever portions 70 are close to each other. When the engagement is advanced in a state of being elastically deformed so that the locking claw portion 65 is aligned with the locking recess 55, the elastically deformed release lever portion 70 is elastically restored, and The pawl portion 65 is engaged with the locking recess 55.

  When removing from the arm part 34 for exchanging the operation part 35 from the attachment completion state shown in FIG. 28, the following procedure may be performed. First, a finger is approached from the back side of the operation unit 35, and for example, the tip portions of the pair of left and right release lever portions 70 are operated with a thumb and an index finger. More specifically, the knob operation is performed so that the distal ends of the pair of left and right release lever portions 70 are elastically deformed in a direction in which they approach each other. As a result, as shown in FIG. 29, the locking claw portion 65 is disengaged from the locking recess 55. In the state shown in FIG. 29, the operating portion 35 is grasped with a hand opposite to the hand on which the release lever portion 70 is being operated, and the guide protrusions 51, 52 and the guide groove portion 61, If the operation unit 35 is pulled in a direction to release the fitting with 62, the operation unit 35 is removed from the arm unit 34.

  Although the embodiment has been described above, the present invention is not limited to the embodiment, and can be appropriately changed within the scope described in the scope of claims. For example, the invention includes the following cases. . The arm part 34 as the arm member and the operation part 35 as the operation knob are not limited to those for the lock mechanism, and may be used for opening and closing operations such as doors, bonnets, trunk lids, etc. in vehicles. , It may be used for various operations other than those for vehicles.

  The locking recess 55 may be formed on the arm portion 34 side, while the locking claw portion 65 may be formed on the operation portion 35 side. The release lever portion 70 is not limited to the case where it is used for forming the locking recess 55 or the locking claw portion 65. You may set so that it may function only for external force provision of the direction to cancel | release. Further, without providing a pair of left and right locking recesses 55 (locking claw portions 65), only one may be provided, or three or more may be provided. The number of release levers 70 may be set according to the number of the locking recesses 55 (locking claw portions 65). The number of the pair of left and right guide protrusions 51 and 52 (guide groove portions 61 and 62) can be only one pair or three or more pairs, or can be only one.

  For example, the housing recess 50 has a cylindrical shape, and the fitting projection 60 has a piston shape that is slidably fitted into the housing recess 50, for example (separate guide protrusions 51, 52 and guides). The groove portions 61 and 62 are not formed), and the locking recess 55 and the locking claw portion 65 may be used to restrict the removal thereof. In this case, it is possible to set so as to release the engagement between the engagement recess 55 and the engagement claw portion 65 using the release lever portion 70. In addition, from the viewpoint of improving the appearance of the operation unit 35, it is preferable to form a complicated functional part on the arm part 35 side as much as possible. Therefore, the release lever part 70 is formed on the arm part 34 side. It is preferable to keep it. Of course, the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.
