TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mechanical shift lock device that limits a shift operation of a shift lever or the like that operates a transmission of a vehicle.
[0002]
[Prior art]
A vehicle that employs an automatic transmission includes a shift lock mechanism that mechanically locks a shift lever for operating the automatic transmission at a specific position such as a parking range position. A shift lock device is provided which releases a locked state by operating a cable or the like in mechanical linkage with a stepping-on operation of a brake pedal or the like.
[0003]
[Problems to be solved by the invention]
By the way, such a shift lock device is preferably provided very close to the brake pedal because it is interlocked with the depressing operation of the brake pedal, but the space near the brake pedal is narrow, and a switch for a brake lamp is also provided. ing. For this reason, it was difficult to secure an installation space for the shift lock device.
[0004]
An object of the present invention is to provide a mechanical shift lock device that can be installed in a narrow range near a brake pedal in consideration of the above fact.
[0005]
[Means for Solving the Problems]
A mechanical shift lock device according to claim 1, wherein a housing provided adjacent to a brake means displaced by a vehicle braking operation and a braking release operation, and a housing provided inside the housing and a predetermined shift operation of the vehicle. A shift operation means interlocking member connected to shift operation means for changing a shift range of the transmission, and displaced in conjunction with a shift operation of the shift operation means from a shift position corresponding to a predetermined shift range of the transmission; A state in which the shift operation means is provided inside the housing and is displaced in conjunction with the displacement of the braking means by the braking operation and the braking release operation, and is located at a shift position corresponding to a predetermined shift range of the transmission. When the braking means is released from the braking operation, the engaging means engages with the shift operation means interlocking member to interlock with the shift operation means. And locking means for limiting the displacement of the timber, it is moved by the locking meansAt the same time, it is detachable from the housing and is connected to the locking means when mounted.A moving body that is electrically connected to another electric circuit such as a circuit of a brake lamp that operates in a braking operation state of the braking means, and that is interlocked with a displacement of the locking means during the braking operation; And a movable body detecting means which is turned on upon detecting the approaching movement of the housing and which is detachably provided on the outer peripheral portion of the housing.
[0006]
In the mechanical shift lock device having the above-described configuration, when the braking means is operated for braking or releasing the braking means, the locking means is displaced in conjunction with these operations. Here, in a state where the shift operation means is located at a shift position corresponding to a predetermined shift range (for example, a parking range) of the transmission of the vehicle, when the brake release operation is performed by the brake release operation, the brake release of the brake means is performed. The lock means displaced in conjunction with the braking release operation is engaged with the shift operation means interlocking member to limit the displacement of the shift operation means interlocking member. Thereby, the shift operation of the shift operation means from the shift position corresponding to the predetermined shift range is restricted, and a so-called shift lock state is set.
[0007]
Further, when the locking means is displaced by the braking operation of the braking means and the moving body approaches the moving body detecting means, the moving body detecting means detects the approaching movement of the moving body and is turned on. The electric circuit is closed. Therefore, for example, when the electric circuit is a circuit of a brake lamp, the brake lamp is turned on to warn the outside of the vehicle that the braking means has been operated.
[0008]
As described above, in the present mechanical shift lock device, since the moving body and the moving body detecting means are integrated with the housing, it is different from a switch of another circuit such as a brake lamp switch as in the conventional shift lock device. It is not necessary to secure the installation space for the device at the location. Therefore, the device can be installed even in a narrow space, such as near the brake pedal (braking means).
[0009]
Further, in the present mechanical shift lock device, the moving body detecting means is detachable from the housing. Therefore, for example, the moving body detecting means is used for maintenance of a device connected to another electric circuit such as a brake lamp circuit. In the case of exchanging, for example, the moving body detecting means is detached from the outside of the housing, and another moving body detecting means is attached instead. Therefore, in the case of such replacement work, the housing is not removed from the predetermined installation position (that is, the installation position near the braking means), and a complicated operation such as positioning of the housing after the operation is unnecessary. Workability is improved.
[0010]
Further, in the present mechanical shift lock device, the moving body is detachable from the housing. For example, when the moving body is replaced or the like during maintenance of a device connected to another electric circuit such as a brake lamp circuit. , The moving body is detached from the outer periphery of the housing, and another moving body is attached instead. Even in such an operation, the housing is not removed from the predetermined installation position (that is, the installation position near the braking means), and in this sense, complicated work such as positioning of the housing after the operation is unnecessary, and workability is improved. Is improved.
[0012]
Claim2The mechanical shift lock device described in claim1The above-mentioned mechanical shift lock device is characterized in that the moving body detecting means and the moving body are included and a switch housing detachable from the housing is provided.
[0013]
In the mechanical shift lock device having the above structure,1In addition to having the function of the mechanical shift lock device described above, the moving body detection means and the moving body are included in the switch housing, so that the moving body can be integrally attached to and detached from the housing with the moving body detection means It is said. Therefore, for example, when performing repair or replacement of the moving body detecting means or the moving body during maintenance of the brake lamp, the moving body or the moving body is detached from the outer peripheral portion of the housing together with the moving body detecting means. Repair or replacement of the detection means. Therefore, for example, when the braking means is a brake pedal and a mechanical shift lock device is installed in a narrow place near the brake pedal, fine adjustment such as positioning of the moving body detection means with respect to the moving body is performed by the brake. It can be performed not in a narrow place such as near the pedal but in another wide place, and the work efficiency can be improved.
[0014]
Claim3The mechanical shift lock device described in claim2In the above-mentioned mechanical shift lock device, the switch housing includes the lock unit, and the lock unit is detachable from the housing together with the moving body detection unit and the moving body.

Further, in the following description, in each of the front, rear, left, right, and up and down directions, a state in which the mechanical shift lock device 10 is installed at a predetermined position of the vehicle is used as a reference.
[0017]
As shown in FIG. 1, the mechanical shift lock device 10 includes a substantially box-shaped housing 12. As shown in FIG. 2, the housing 12 is disposed behind a brake pedal 14 (a side opposite to the direction indicated by the arrow Y in FIG. 2) as a braking means. A guide groove 20 is formed in the longitudinal direction (in the direction of the arrow Z of FIG. 2 and the direction opposite thereto) and opened at the lower end of the housing 12. Inside the guide groove 20, a cylindrical slider 22 as a shift operating means interlocking member is arranged so as to be vertically movable along the guide groove 20. One end of a wire 26 is locked to the lower end of the slider 22, and the slider 26 is displaced by sliding movement of the slider 22.
[0018]
As shown in FIG. 5, the other end of the wire 26 is connected to a shift lever device 30 provided on the passenger compartment side.
[0019]
As shown in FIG. 5, the shift lever device 30 has a longitudinal direction extending in the up-down direction, and rotates around the shaft 32 in the front-rear direction (the direction of the arrow Y in FIG. 5 and the opposite direction) (shift operation). A shift lever 34 is provided as a shift operation means which is rotatably supported, and a detent plate 38 in which a detent groove 36 is formed is provided on the side of the shift lever 34 (on the front side in FIG. 5).

The grooved pin 40 is constantly urged upward by a spring (not shown) provided on the shift lever 34, and moves along the upper edge of the detent groove 36 with the rotation of the shift lever 34. However, the detent groove 36 is partially formed with a downwardly protruding restricting portion 42. In this portion, simply rotating the shift lever 34 causes the grooved pin 40 to contact the restricting portion 42. The rotation of the shift lever 34 is restricted (shift lock state), and the rotation restriction is not released unless the grooved pin 40 is lowered to a position where the shift lever 34 can get over.
[0021]
A cam 46 is provided on the side of the detent plate 38 (on the front side in FIG. 5) so as to be rotatable around the pin 44 to a pin 44 extending from the detent plate 38. The other end of the wire 26 is locked to the cam 46. The cam 46 is formed with a narrow notch 48 that opens rearward (the direction opposite to the direction of arrow Y in FIG. 5), and corresponds to a parking range of an automatic transmission (not shown) of the vehicle. In a state where the shift lever 34 is most rotated forward (the state shown in FIG. 5), the grooved pin 40 enters the inside of the notch 48. For this reason, when the grooved pin 40 is lowered in a state where the grooved pin 40 enters the inside of the cutout portion 48, the cam 46 rotates by the pressing force from the grooved pin 40 and pulls the wire 26.
[0022]
On the other hand, as shown in FIG. 2, a guide groove 52 is formed on the upper end side inside the housing 12 so as to extend in the front-rear direction. The guide groove 52 communicates with the guide groove 20 at a middle portion in the longitudinal direction so as to be orthogonal to the guide groove 20. As shown in FIG. 3, when the left side (the direction opposite to the arrow X direction in FIG. 3) is the depth direction of the guide groove 20 and the guide groove 52, the guide groove 52 becomes deeper than the guide groove 20.

A cylindrical slider 54 is accommodated in the guide groove 52 so as to be movable along the guide groove 52. As shown in FIG. 2, the diameter dimension of the slider 54 is smaller than the depth dimension of the guide groove 52, and at the intersection of the guide groove 20 and the guide groove 52, the depth is lower than the bottom of the guide groove 20 in the depth direction. The slider 54 passes through (ie, the right side).
[0024]
Further, a through hole 56 having an inner diameter smaller than the width of the guide groove 52 and opening at the rear end of the housing 12 is formed at the rear end of the guide groove 52, and one end in the longitudinal direction is formed at the end of the slider 54. The wire 58 locked to the portion penetrates.
[0025]
As shown in FIG. 6, the other end of the wire 58 is connected to a key cylinder 62 of the vehicle. Here, as shown in FIG. 6, when the key 64 inserted into the key cylinder 62 rotates inside the key cylinder 62, the key 64 rotates in conjunction with the key 64 via a pin 66 in the key cylinder 62. A moving cam 68 is accommodated, and the other end of the wire 58 is locked to the cam 68. Therefore, when the key 64 is rotated, the wire 58 is pulled via the pin 66 and the cam 68, and the slider 54 shown in FIG. 2 can be slid rearward along the guide groove 52.
[0026]
Here, as shown in FIG. 3, a block-shaped lock portion 70 protruding leftward is formed from the outer peripheral portion of the slider 54, and is formed on the outer peripheral portion of the slider 22 in the forward direction. A concave portion 72 having a concave shape and a width dimension substantially equal to the width dimension of the slider 54 is formed. For this reason, when the slider 22 is located at a position where the concave portion 72 communicates with the guide groove 52 facing the guide groove 52, when the key 64 in FIG. 6 is turned from the LOCK position to the ACC position and the wire 58 is pulled, The portion 70 enters the concave portion 72 and restricts the downward movement of the slider 22.
[0027]
As shown in FIG. 2, a guide groove 82 is formed below the guide groove 52 inside the housing 12 so as to extend in the front-rear direction (that is, parallel to the guide groove 52). I have. Like the guide groove 52, the guide groove 82 communicates with the guide groove 20 at a middle portion in the longitudinal direction so as to be orthogonal to the guide groove 20. As shown in FIG. 4, when the right side (the direction of the arrow X in FIG. 4) is the depth direction of the guide groove 20 and the guide groove 82, the guide groove 82 is formed to be deeper than the guide groove 20. I have.
[0028]
Further, inside the guide groove 82, a cylindrical slider 84 as a locking means is accommodated movably along the guide groove 82. As shown in FIG. 4, a flat portion 85 which is substantially flush with the bottom of the guide groove 20 is formed on the rear end side of the slider 84, and the slider 22 moves the guide groove 20 downward. The slider 22 is placed on the flat portion 85 by moving.
[0029]
Further, as shown in FIGS. 2 and 4, a through hole 86 having an inner diameter smaller than the width of the guide groove 82 and opening at the front end of the housing 12 is formed at the front end of the guide groove 82. A pin 88 projecting from the front end of the slider 84 penetrates and projects outside the housing 12. This pin 88 faces a pressing portion 92 formed on the brake pedal 14. Here, the brake pedal 14 is urged rearward by an urging force of an urging means (not shown) such as a spring. Therefore, the pin 88 is constantly pressed rearward by the pressing portion 92 of the brake pedal 14. ing. Between the front end of the slider 84 and the front end of the guide groove 82, there is provided a compression coil spring 90 whose urging force is smaller than the urging force of the urging means for urging the brake pedal 14. The slider 84 is always urged forward by the urging force of the coil spring 90.
[0030]
Further, as shown in FIGS. 2 and 4, a block-shaped lock portion 96 protruding leftward is formed from the outer peripheral portion of the slider 84, and the pin 88 is pressed by the brake pedal 14, and the slider 84 In a state in which is moved backward by a predetermined stroke (the state shown in FIG. 4), the lock portion 96 enters the guide groove 20. At this time, if the slider 22 is located on the upper end side of the guide groove 20, the lock portion 96 contacts the lower end of the slider 22 (that is, the end on which the wire 26 is locked), and Restrict the sliding movement of the lower side of 22.
[0031]
Further, as shown in FIG. 4, a fitting groove 98 is formed in the lock portion 96 so that a moving contact 102 as a moving body of the brake lamp switch 100 can be fitted.
[0032]
Here, as shown in FIG. 1, the brake lamp switch 100 includes a box-shaped switch housing 104 and can be fitted into a frame-shaped holding wall 106 formed on the outer peripheral portion of the housing 12. A plurality of engaging projections 108 are formed on the inner peripheral portion of the holding wall 106 in the longitudinal direction in the left-right direction (that is, the direction of the arrow X in FIG. 1 and the opposite direction). When the switch housing 104 is fitted into the holding wall 106, it engages with a plurality of engagement grooves 110 formed in the side wall 104 </ b> A of the switch housing 104 facing the holding wall 106, and moves in the front-rear direction of the switch housing 104 (the arrow Y direction in FIG. And its opposite direction). A stopper 112 having a triangular prism shape is formed on the side wall 104A of the switch housing 104. When the switch housing 104 is fitted into the holding wall 106, the stopper 112 is formed on the inner peripheral portion of the holding wall 106 in correspondence with the stopper 112. The stopper 112 is fitted into the groove 114 thus formed, whereby the switch housing 104 is held by the holding wall 106.
[0033]
A frame-shaped connector portion 116 is formed on the upper wall 104B of the switch housing 104 on the opposite side of the outer peripheral portion of the housing 12, and the other end of the cable having one end connected to the brake lamp. The male connector (not shown) formed in the connector can be fitted.
[0034]
Further, as shown in FIG. 4, the inside of the switch housing 104 is hollow, and a guide groove 122 that opens toward the outer peripheral side of the housing 12 is formed in the bottom wall 104 </ b> C of the switch housing 104. The slider 124 of the moving contact 102 is guided by the guide groove 122 and slidably fitted in the front-rear direction (the direction of the arrow Y in FIG. 4 and the opposite direction). The slider 124 has a block-shaped protruding portion 126 protruding toward the housing 12, and penetrates through the rectangular through hole 128 formed on the outer peripheral portion of the housing 12 to enter the inside of the housing 12. The slider 84 can be fitted into the fitting groove 98. Therefore, when the slider 84 moves along the guide groove 82 in a state where the protrusion 126 is fitted into the fitting groove 98, the slider 124 slides integrally.
[0035]
A metal piece 130 is fixed to an end surface of the slider 124 opposite to the protruding portion 126. The metal piece 130 is bent rearward of the front end side of the slider 124 and toward the upper wall 104B of the switch housing 104, and has a biasing force toward the upper wall 104B with the bent portion as a center.
[0036]
On the other hand, as shown in FIG. 1, a pair of metal pieces 120 constituting a fixed contact 118 as a moving body detecting means are provided inside the connector section 116. As shown in FIG. 4, the metal piece 120 penetrates the upper wall 104B of the switch housing 104 (that is, the bottom of the connector portion 116) and is bent rearward at substantially a right angle along the back surface of the upper wall 104B. When the slider 124 slides forward, the tip of the metal piece 130 comes into contact with each metal piece 120 and conducts (that is, the movement of the moving contact 102 is detected by the metal piece 130), and the brake lamp is turned on. Can be done.
[0037]
Next, the operation of the present embodiment will be described.
In this mechanical shift lock device 10, the shift lever 34 of the shift lever device 30 shown in FIG. 5 is turned most forward to change the automatic transmission of the vehicle from the parking range to another shift range. When the grooved pin 40 is lowered at the set position (the state shown in FIG. 5), the cam 46 rotates around the pin 44 and the wire 26 is pulled, and the slider 22 shown in FIG. 2 slides down along the guide groove 20. Moving.
[0038]
Here, when lowering the grooved pin 40, the key 64 is not inserted into the key cylinder 62 shown in FIG. 6, or the key 64 is located at the LOCK position even if the key 64 is inserted. In this state, the wire 58 is pulled, so that the lock portion 70 of the slider 54 enters the concave portion 72 of the slider 22. For this reason, the slider 22 cannot slide downward along the guide groove 20, and the grooved pin 40 cannot be lowered. Therefore, in this state, the grooved pin 40 cannot get over the restriction portion 42 of the detent groove 36, the shift lever 34 is locked, and the rotation operation of the shift lever 34 for changing from the parking range to another shift range is performed. Can not.
[0039]
In this state, when the key 64 is inserted into the key cylinder 62 and the key 64 is rotated from the LOCK position to the ACC position, the slider 54 moves forward through the pin 44, the cam 46, and the wire 58 into the guide groove 52. Accordingly, the lock portion 70 of the slider 54 is disengaged from the concave portion 72 of the slider 22, and the lock of the slider 22 by the lock portion 70 (slider 54) is released.
[0040]
When the grooved pin 40 is lowered, if the lock portion 96 of the slider 84 enters the guide groove 20, the lower end of the slider 22 contacts the lock portion 96, and the slider 22 moves downward along the guide groove 20. The sliding movement cannot be performed, and the grooved pin 40 cannot be lowered. Therefore, the shift lever 34 is locked as in the case of locking by the lock portion 70 (slider 54).
[0041]
In this state, when the brake pedal 14 is depressed and the brake pedal 14 is displaced forward to the dashed line in FIG. 2, the pressing force of the pressing portion 92 of the brake pedal 14 pressing the pin 88 of the slider 84 is released, The slider 84 slides forward along the guide groove 82 as the brake pedal 14 is depressed by the urging force of the compression coil spring 90. Thus, when the lock portion 96 of the slider 84 is separated from the guide groove 20, the lock of the slider 22 by the lock portion 96 (slider 84) is released.
[0042]
As described above, in a state where both the lock by the lock portion 70 (slider 54) and the lock by the lock portion 96 (slider 84) are released, the slider 22 slides downward along the guide groove 20. The shift lever 34 can be rotated by lowering the grooved pin 40.
[0043]
For this reason, it is possible to prevent the automatic transmission from changing from the parking range to another shift range in a state where the brake pedal 14 is not depressed and the key 64 is not turned to the ACC position.
[0044]
In addition, when the brake pedal 14 is depressed, not only when the shift lever 34 is rotated, but also when the brake lever 14 is depressed, the pressing portion of the brake pedal 14 is When the pressing force of the compression coil spring 90 is released and the slider 84 slides forward along the guide groove 82 as the brake pedal 14 is depressed by the urging force of the compression coil spring 90, the fitting groove 98 and the protrusion 126 are moved. The slider 124 integrally connected to the slider 84 via the slider slides forward along the guide groove 122. As a result, the metal piece 130 of the moving contact 102 comes into contact with each metal piece 120 of the fixed contact 118 and becomes conductive (that is, the brake lamp switch 100 is turned on). As a result, the brake lamp is turned on to warn the following vehicle that the brake operation has been performed.
[0045]
As described above, in the present mechanical shift lock device 10, the switch housing 104 is integrated with the housing 12 by mounting the switch housing 104 of the brake lamp switch 100 on the housing 12, and the brake lamp switch 100 is slid by the slider 84. Is turned ON / OFF, so that there is no need to secure a space for installing the device avoiding the brake lamp as in a conventional shift lock device, and the device can be sufficiently installed in a narrow space near the brake pedal 14.
[0046]
Further, in the present mechanical shift lock device 10, by fitting the switch housing 104 into the holding wall 106 from the outside of the housing 12, the protrusion 126 of the slider 124 is fitted into the fitting groove 98 of the slider 84, and The switch housing 104 is held by 106 and the brake lamp switch 100 is integrated with the housing 12.
[0047]
Therefore, when replacing the brake lamp switch 100 for maintenance of the brake lamp or the like, the switch housing 104 (the brake lamp switch 100) is removed from the holding wall 106 and another switch housing 104 (the brake lamp switch 100) is held. The replacement of the brake lamp switch 100 is completed by fitting into the 106. Since the brake lamp switch 100 can be replaced simply and quickly in this way, even if, for example, the user of the vehicle requests replacement and repair of the brake lamp switch 100, it can respond quickly. Moreover, since only the brake lamp switch 100 needs to be replaced without changing the components inside the housing 12 of the mechanical shift lock device 10, the replacement cost is reduced.
[0048]
When the brake lamp switch 100 is repaired instead of being replaced, the switch housing 104 (the brake lamp switch 100) is detached from the holding wall 106 so that the mechanical shift lock device 10 is provided near the brake pedal 14. Repair work can be performed in another large work place without performing repair work in a narrow place. Therefore, the number of steps required for repair work of the brake lamp switch 100 can be reduced.
[0049]
Further, when the brake lamp switch 100 is replaced or repaired as described above, the housing 12 does not need to be removed from the installation location near the brake pedal 14, so that the housing 12 is There is no need to perform positioning. Therefore, also in this sense, the number of steps can be reduced.
[0050]

Differently, the holding wall 106 of the housing 12 is not formed, and instead, a circular hole 182 is formed at the rear end of the housing 12.
[0058]
Here, as shown in FIG. 9, the circular hole 182 communicates with the guide groove 82 inside the housing 12, and the cylindrical pressing portion 184 extending from the rear end of the slider 84 has a circular hole. 182.
[0059]
As shown in FIG. 8, a pair of holding walls 186 extend rearward from the outer peripheral portion of the housing 12 (the side opposite to the arrow Y direction in FIG. 9). These holding walls 186 are formed in an arc shape along the peripheral end of the circular hole 182, and the rear end of each holding wall 186 is bent at a substantially right angle inward in the radial direction of the circular hole 182.
[0060]
Further, a rectangular hole 188 opened rearward is provided near the left end (opposite side to the arrow X direction in FIG. 8) of the upper holding wall 186 (the side in the arrow Z direction in FIG. 8). Is formed. Here, as shown in FIGS. 10 and 11, a cantilever-shaped beam portion 190 extends from the inner periphery of the hole 188, and further, an upper holding wall is provided at the tip of the beam portion 190. A stopper 192 having an inclined surface 191 that is inclined so as to gradually protrude rearward from the rear end of the housing 12 as it approaches 186 forms a snap fit 194. When the stopper 192 of the snap fit 194 is pressed from the rear, the beam portion 190 is elastically deformed, and the stopper 192 enters the inside of the hole 188. When the pressing force is released, the stopper 192 is re-formed by the elasticity of the beam portion 190. To project outside.
[0061]
Also, as shown in FIG. 8, a brake lamp switch 200 is attached to the above-described circular hole 182. The brake lamp switch 200 includes a switch housing 202 having a substantially cylindrical shape. A pair of flange portions 203 facing each other is formed from an outer peripheral portion of the switch housing 202 via the switch housing, and the switch housing 202 is rotated around an axis in a state where the switch housing 202 is fitted into the circular hole 182. Then, each flange portion 203 is sandwiched between the holding wall 186 and the rear end wall of the housing 12 to prevent the switch housing 202 from coming off. When the switch housing 202 is fitted into the circular hole 182 and rotated, the one flange portion 203 presses the slope portion 191 of the stopper 192 to push the stopper 192 into the hole 188. When completely sandwiched between the holding wall 186 and the rear end wall of the housing 12, the stopper 192 projects outside the hole 188 due to the elasticity of the beam portion 190, and the reverse rotation of the switch housing 202 is prevented by the stopper 192. You.
[0062]
As shown in FIG. 9, the switch housing 202 is formed with a circular hole 204 opened at the front end (in the direction of the arrow Y in FIG. 9), and a hole 216 opened at the front end inside. A slider 206 having a bottom and having a cylindrical shape with a bottom is slidably moved along the circular hole 204 in the front-rear direction (the direction of the arrow Y in FIG. 9 and the direction opposite thereto). Further, inside the slider 206, a pin 208 whose tip side projects from the slider 206 and abuts on the pressing portion 184 of the slider 84 is used. A circular hole (not shown) opened at the rear end of the pin 208 is formed. A support shaft 214 protruding from the bottom of the slider 206 toward the open end is inserted into the pin 208 and supported by the support shaft 214. In this state, it is slidable in the front-rear direction. Further, a plurality of ring-shaped locking grooves 210 are formed on the outer peripheral portion of the pin 208 on the rear end side with respect to the axial middle portion. Any one of the locking grooves 210 is locked so that a ring-shaped locking protrusion 212 formed at an intermediate portion in the axial direction inside the slider 206 enters, and the pin 208 slides. Is restricted. Here, a gap 218 is formed inside the peripheral wall of the slider 206 (that is, between the locking projection 212 and the outer peripheral part), and the peripheral wall of the hole 216 radially inside the gap 218 has a spring force. However, the peripheral wall can be bent radially outward, and can be restored by a spring force. Therefore, when the pin 208 is pushed into or pulled out of the hole 216 with a force equal to or greater than a predetermined amount, the locking convex portion 212 is pressed radially outward by the slope of the locking groove 210, whereby the hole 216 When the peripheral wall bends and the engaging protrusion 212 enters another adjacent engaging groove 210, the peripheral wall of the hole 216 is restored by the spring force.
[0063]
Further, a flange portion 220 extending radially outward is formed at an axially intermediate portion of an outer peripheral portion of the slider 206, and a ring formed at an axially intermediate portion of an inner peripheral portion of the slider 206. Into the groove 222. The width of the groove 222 is longer than the width of the flange 220. Therefore, the range in which the flange 220 can move in the axial direction of the slider 206 inside the groove 222 is the range of the sliding movement of the slider 206 with respect to the switch housing 202. It is said.
[0064]
Further, a pair of moving contacts 224 are fixed to the front end of the flange 220 so as to be opposed to each other via the slider 206 and serve as moving bodies electrically connected to each other. On the front side of 224, a pair of fixed contacts 226 as moving body detecting means is fixed to the groove 222 so as to face each moving contact 224. These fixed contacts 226 are electrically connected to a pair of metal pieces 230 of a connector portion 228 formed at the rear end of the switch housing 202, and are fixed by moving contacts 224 contacting each fixed contact 226. The contact 226 detects the approaching movement of the moving contact 224, and the fixed contact 226 is made conductive.
[0065]
A compression coil spring 232 is provided between the bottom of the slider 206 and the bottom of the switch housing 202, and urges the slider 206 forward. Here, the sum of the urging force of the compression coil spring 232 and the urging force of the compression coil spring 90 is smaller than the urging force of the urging means (not shown) for urging the brake pedal 14 rearward. Therefore, the slider 84 is pushed into the guide groove 82 by the pressing force from the brake pedal 14, and the slider 206 is fixed by the flange portion 220 by the pressing force from the brake pedal 14 received through the slider 84. It is pushed into the inside of the circular hole 204 until it comes into contact with the end opposite to the contact 226. When the brake pedal 14 is depressed against the urging force of the urging means, the slider 84 slides forward along the guide groove 82 as the brake pedal 14 is depressed by the urging force of the compression coil spring 90. . Thus, when the lock portion 96 of the slider 84 is separated from the slider 22, the locked state of the slider 22 by the lock portion 96 (slider 84) is released. Further, when the slider 84 slides in accordance with the depressing movement of the brake pedal 14, the slider 206 slides forward along with the sliding movement of the slider 84 by the urging force of the compression coil spring 232. As a result, the moving contact 224 of the flange portion 220 comes into contact with the fixed contact 226 of the groove 222, and the moving contact 224 and the fixed contact 226 are conducted, and a brake lamp (not shown) is turned on.
[0066]
Here, in the present mechanical shift lock device 180, the switch housing 202 is rotated around an axis in a state where the switch housing 202 is inserted into the circular hole 182 of the housing 12, and each flange portion 203 is held on each holding wall 186. By locking with the snap fit 194 (stopper 192) in this state, the brake lamp switch 200 is mounted on the housing 12 and becomes integral with the housing 12. In addition, the brake lamp switch 200 is removed from the housing 12 by releasing the lock by the snap fit 194 and rotating the switch housing 202 in a direction opposite to that at the time of mounting to remove the switch housing 202 from the circular hole 182.
In this mechanical shift lock device 180 as well, like the mechanical shift lock device 10 according to the first embodiment and the mechanical shift lock device 160 according to the second embodiment, the brake lamp switch 200 is connected to the housing 12. By mounting the switch housing 202, the switch housing 202 is integrated with the housing 12, and the brake lamp switch 100 is turned on / off by the sliding movement of the slider 84. There is no need to secure the installation space for the device, and the device can be installed sufficiently in a narrow space near the brake pedal 14.
[0067]
Further, like the mechanical shift lock device 10 according to the first embodiment and the mechanical shift lock device 160 according to the second embodiment, the brake lamp switch 200 is replaced when the brake lamp is maintained. When performing this, the switch housing 202 (brake lamp switch 200) is removed from the circular hole 182, and another switch housing 202 (brake lamp switch 200) is fitted into the circular hole 182, thereby completing the replacement of the brake lamp switch 200. . As described above, since the brake lamp switch 200 can be replaced easily and quickly, even when, for example, the vehicle user requests replacement and repair of the brake lamp switch 200, it is possible to quickly respond. Moreover, since only the brake lamp switch 200 needs to be replaced without changing the components in the housing 12 of the mechanical shift lock device 180, the replacement cost is reduced.
[0068]
When the brake lamp switch 200 is repaired instead of being replaced, the switch housing 202 (the brake lamp switch 200) is removed from the circular hole 182 so that the vicinity of the brake pedal 14 provided with the mechanical shift lock device 180 is provided. Repair work can be performed in another large work place without performing repair work in a narrow place. Therefore, the man-hour required for the repair work of the brake lamp switch 200 can be reduced.
[0069]
Further, when replacing or repairing the brake lamp switch 200 as described above, it is not necessary to remove the housing 12 from the installation location near the brake pedal 14, so that the housing 12 is There is no need to perform positioning, and in this sense, man-hours can be reduced.
[0070]
In general, the position of the brake pedal 14 in a state where it is urged by the urging means (that is, the rear stroke end) is slightly different for each vehicle, so that the mechanical shift according to the first embodiment is performed. In the configuration of the lock device 10 and the mechanical shift lock device 160 according to the second embodiment, in order to turn on the brake lamp with the same depression amount, the brake lamp switch 100 is mounted on the housing 12 or after mounting. The distance between the metal piece 120 of the fixed contact 118 and the metal piece 130 of the moving contact 102, that is, the moving stroke of the moving contact 102 must be finely adjusted.
[0071]
However, in the mechanical shift lock device 180 according to the present embodiment, the brake pedal 14 is once depressed to the front end side stroke end in a state where the brake lamp switch 200 is mounted on the housing 12, and the depression is rapidly released in that state. As a result, the pressing portion 92 of the brake pedal 14 vigorously hits the pin 88 of the slider 84 and pushes the slider 84 into the guide groove 82 against the urging force of the compression coil spring 90. 184) tries to push the slider 206 into the inside of the circular hole 204 of the switch housing 202 against the urging force of the compression coil spring 232.
[0072]
Here, even when the flange portion 220 comes into contact with the end of the groove 222 on the side opposite to the fixed contact 226, the slider 84 pushes the slider 206 without the brake pedal 14 reaching the stroke end in the rear. When the brake pedal 14 is to be inserted, the pin 208 is pushed into the hole 216 of the slider 206 by the pressing force from the slider 84 (the pressing portion 184) until the brake pedal 14 reaches the stroke end. As a result, the locking protrusion 212 moves radially outward along the slope of the locking groove 210, the inner peripheral wall of the switch housing 202 bends, and the locking protrusion 212 is disengaged from the locking groove 210 and enters there. The pin 208 enters the locking groove 210 corresponding to the position of the brake pedal 14 at the stroke end on the front end side of the locking groove 210 that has been moved, thereby restricting the movement of the pin 208. Here, no matter which locking groove 210 the locking protrusion 212 enters, the moving stroke of the slider 206 until the moving contact 224 contacts the fixed contact 226 is the same. Therefore, even if the position of the brake pedal 14 at the rear stroke end is slightly different for each vehicle, the movable contact 224 and the fixed contact 226 can be brought into contact with the same amount of depression, and the same depression can be achieved. There is no need to perform fine adjustment work to bring the moving contact 224 and the fixed contact 226 into contact with each other.
[0073]
In the present embodiment, as described above, since the locking protrusion 212 enters the locking groove 210 corresponding to the position of the brake pedal 14 at the rear stroke end, the moving contact 224 is formed with the same depression amount. And the fixed contact 226 can be brought into contact with each other, but such a mechanism is not necessarily required. For example, the slider 206 and the pin 208 may be completely integrated.
[0074]
Further, in the present embodiment, the tip of the pin 208 is only in contact with the pressing portion 184 of the slider 84. However, for example, a male screw is formed on the outer periphery of the tip of the pin 208, and the pressing portion 184 is formed. By forming a female screw into which the male screw of the pin 208 can be screwed into the rear end, and fitting the switch housing 202 of the brake lamp switch 200 into the circular hole 182 of the housing 12 and rotating the same, the male screw of the pin 208 is formed. The pin 208 and the pressing part 184 may be integrated with each other by screwing the female screw of the pressing part 184 with the female screw of the pressing part 184.
[0075]
(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.
[0076]
FIG. 12 is a perspective view of a mechanical shift lock device 260 according to the present embodiment, and FIG. 13 is a cross-sectional view of a main part of the mechanical shift lock device 260 according to the present embodiment. ing.
[0077]
As shown in these figures, in the mechanical shift lock device 260, the internal configuration is substantially the same as the brake lamp switch 200 of the mechanical shift lock device 180 according to the third embodiment, A small-diameter cylinder in which an outer diameter is smaller than that of the switch housing 202 at the front end of the switch housing 202 of the brake lamp switch 262 having an effect, and an external thread 264 is formed on the outer periphery, and a nut 272 for a stopper is further screwed. A portion 266 is provided, and a pin 208 projects through the small-diameter cylindrical portion 266.
[0078]
Further, outside the circular hole 182 of the housing 12, the holding wall 186 and the snap fit 194 as in the mechanical shift lock device 180 according to the third embodiment are not formed. A female screw 268 corresponding to the male screw 264 of the small-diameter cylindrical portion 266 is formed on the inner peripheral portion. Further, as shown in FIG. 12, a rectangular window 270 opened to the left (toward the direction opposite to the arrow X direction in FIG. 12) is formed in the housing 12. As shown in FIG. 13, the vicinity of the rear end of the pressing portion 184 can be visually recognized from outside the housing 12 through the window 270.
[0079]
Therefore, when the brake lamp switch 262 is mounted on the housing 12 in the mechanical shift lock device 260, the male screw 264 of the small-diameter cylindrical portion 266 is screwed into the female screw 268 of the circular hole 182. At this time, by screwing the male screw 264 into the female screw 268 while visually checking the vicinity of the rear end of the slider 84 from the window 270, it can be confirmed whether or not the front end of the pin 208 has contacted the rear end of the pressing portion 184. Further, when the nut 272 is rotated around the small-diameter cylindrical portion 266 to make contact with the rear end wall of the housing 12 in a state where the tip of the pin 208 is in contact with the rear end of the pressing portion 184, the nut 272 serves as a stopper, The rotation of the housing 202 around its own axis is restricted, and the pin 208 is held in a state where the tip of the pin 208 contacts the rear end of the slider 84.
[0080]
In this state, the nut 272 is rotated around the small-diameter cylindrical portion 266 to separate it from the rear end wall of the housing 12, and the switch housing 202 (small-diameter cylindrical portion 266) is rotated in a direction opposite to the direction at the time of mounting. The brake lamp switch 262 is removed from the housing 12. As described above, in the present mechanical shift lock device 260, although there is a difference between the screwing of the circular hole 182 into the female screw 268 and the fixing by the holding wall 186 and the snap fit 194 formed around the circular hole 182, the circular hole 182 is different. The mechanical shift lock device 180 according to the third embodiment is basically similar in that the brake lamp switch 262 is fixed by rotating the switch housing 202 into the connector housing 182 and the brake lamp switch 262 is removed by reverse rotation. Therefore, the same effects as those of the mechanical shift lock device 180 according to the third embodiment can be basically obtained.
[0081]
(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described.
[0082]
FIG. 14 is an exploded perspective view of a mechanical shift lock device 300 according to the present embodiment.
[0083]
As shown in the figure, the mechanical shift lock device 300 includes a substantially box-shaped housing 302. Here, as shown in the sectional views of FIGS. 17 and 18, inside the housing 302, like the mechanical shift lock devices 10, 160, 180, 260 according to the first to fourth embodiments, , A guide groove 20, and a guide groove 52 are formed, and a slider 22 is disposed in the guide groove 20 so as to be slidable vertically along the guide groove 20, and a slider 54 is formed in the guide groove 52. It is arranged slidably in the front-rear direction along 52. However, as shown in FIG. 17, in the present embodiment, unlike the mechanical shift lock devices 10, 160, 180, and 260 according to the first to fourth embodiments, The guide groove 20 and the guide groove 52 are formed so that the guide groove 52 is located. Therefore, in the present embodiment, the lock portion 70 of the slider 54 is formed so as to protrude leftward from the slider 54.
[0084]
As shown in FIG. 15, the right and left ends of the housing 302 (in the direction of the arrow X in FIG. 15) are located at the center in the vertical direction (the direction of the arrow Z in FIG. 15 and the opposite direction). A block-shaped protruding portion 304 extending in the longitudinal direction (in the direction of the arrow Y and the direction opposite thereto) is formed. The protruding portion 304 can enter a long hole 308 formed in a bracket 306 fixed to a predetermined position on the rear side of the brake pedal 14 (see FIG. 2). In the retracted state, the housing 302 is slidable along the elongated hole 308 in the front-rear direction with respect to the bracket 306 by a predetermined range.
[0085]
Further, a pair of through-holes 310 penetrating in the left-right direction are formed at both ends in the vertical direction of the housing 302. These through holes 310 have a long hole shape extending in the front-rear direction, and when the protrusion 304 enters the long hole 308, the brackets 306 face each other through the long hole 308. The housing 302 is fixed to the bracket 306 by screwing a nut 316 to a bolt 314 penetrating the through hole 310 and the elongated hole 312 and tightening the housing 302 and the bracket 306. Is done. In this state, by loosening the tightening by the bolt 314 and the nut 316, the housing 302 can be slid in the front-rear direction with respect to the bracket 306 without removing the housing 302 from the bracket 306.
[0086]
As shown in FIG. 14, the housing 302 is formed with a rectangular switch mounting portion 318 that is open at the front end and the left end of the housing 302, and is formed in the front-rear direction (the direction indicated by the arrow Y in FIG. The switch housing 332 of the brake lamp switch 330 whose dimensions in the opposite direction) and the left-right direction (the direction of the arrow X in FIG. 14 and the opposite direction) are set to the switch mounting portion 318 or more can be fitted. . Also, as shown in FIG. 17, a locking means having a substantially cylindrical shape and a hemispherical tip protruding from a circular hole 336 formed at the front end of the switch housing 332 inside the brake lamp switch 330 as shown in FIG. The slider 334 is moved so as to be movable in the front-rear direction (the direction of the arrow Y in FIG. 17 and the direction opposite thereto).
[0087]
From the rear end of the slider 334, a block-shaped lock portion 338 is formed so as to protrude leftward (the direction opposite to the direction of arrow X in FIG. 17), and is opened at the left end of the switch housing 332. It enters the housing 302 through the opening 340 and the opening 342 corresponding to the opening 340 and opened at the right end of the housing 302 in the switch mounting portion 318.
[0088]
Here, the size of the opening 340 and the opening 342 in the front-back direction is longer than the size of the locking portion 338 in the front-back direction. 334 can be slid in the front-rear direction.
[0089]
Further, when the lock portion 338 is in contact with the rear end of the opening 340 (the state shown in FIG. 17), the lock portion 338 enters the guide groove 20, and the lock portion 338 enters the guide groove 20 to move the slider. When the lock portion 338 abuts on the lower end portion of the slider 22, the lock portion 338 limits the sliding movement of the slider 22 downward. Therefore, the pressing portion 92 (see FIG. 2) of the brake pedal 14 presses the slider 334 inward of the housing 302 by the urging force of the urging means, and slides the slider 334 rearward, thereby locking the lock portion. At 338, the sliding movement of the slider 22 can be restricted. That is, the slider 334 of the mechanical shift lock device 300 has basically the same operation as the slider 22 of the mechanical shift lock device 10 according to the first embodiment, although the form is different. .
[0090]
Further, a compression coil spring 344 is provided between the rear end of the slider 334 and the rear end wall of the housing 302, the compression force being smaller than the urging force of the urging means for urging the brake pedal 14 rearward. , The slider 334 is urged forward. Therefore, when the brake pedal 14 is depressed, the slider 334 moves forward with the depressing movement of the brake pedal 14 due to the urging force of the compression coil spring 344.
[0091]
A metal piece 346 as a moving body is provided on the rear end side of the slider 334 and on the opposite side of the lock portion 338 via the slider 334. The rear end of the metal piece 346 is fixed to the slider 334. The front end of the metal piece 346 is bent rightward (in the direction of arrow X in FIG. 17) from the fixed part, and the pressing force is applied from the state where the bent part is pressed leftward. Is released, the original shape is restored by the spring force.
[0092]
On the other hand, as shown in FIG. 14, a frame-shaped connector portion 348 is formed on the left end portion of the housing 302 in a generally convex shape and opened to the left, and inside the connector portion 348. Is provided with a pair of metal pieces 350 as moving body detecting means. Here, as shown in FIG. 17, the metal piece 350 is bent in a crank shape, one end of which penetrates through the left end wall of the housing 302 to enter the inside, and further, the inside of the housing 302 Along the left end wall. One end of the metal piece 350 (that is, the end that enters the inside of the housing 302) corresponds to the metal piece 346 fixed to the slider 334. When the slider 334 moves a predetermined stroke forward, the metal piece 346 is moved. Comes into contact with the metal piece 350, whereby the approaching movement of the metal piece 346 is detected by the metal piece 350 and the metal piece 350 is made conductive.
[0093]
As shown in FIG. 14, the mechanical shift lock device 300 includes a stopper 352. The stopper 352 is a metal plate bent in a substantially L-shape. One end of the stopper 352 is arranged along the left end wall of the housing 302 around the bent portion, and the other end is arranged along the front end wall of the housing 302. . On one end side of the stopper 352, a convex-shaped through hole 358 corresponding to the connector portion 348 is formed. When the stopper 352 is arranged along the housing 302, the connector portion 348 passes through the through hole 358. Protrude.
[0094]
In addition, through the through hole 358 on one end side of the stopper 352, on both ends of the stopper 352 in the up-down direction (the direction of the arrow Z in FIG. 14 and the opposite direction), the front and rear directions correspond to the through holes 310 of the housing 302. When the stopper 352 is disposed along the housing 302, each of the long holes 354 communicates with the through-hole 310, and the above-described bolt 314 passes through to the housing 302. It is fixed integrally. Further, a notch 356 is formed at the other end of the stopper 352 corresponding to the slider 334. As shown in FIG. 17, the slider 334 projecting from the switch housing 332 projects through the notch 356. .
[0095]
In the mechanical shift lock device 300, the switch housing 332 is fitted into the switch mounting portion 318 of the housing 302 from the outside of the housing 302, and the stopper 352 is further attached, and the housing 302 is fixed to the bracket 306 by bolts 314 and nuts 316. , The mechanical shift lock device 300 is attached. Before completely fixing the housing 302 to the bracket 306 with the bolts 314 and the nuts 316, the housing 302 and the stopper 352 are moved in the front-rear direction (the direction of the arrow Y in FIG. 14 and the direction opposite thereto) with the bolts 314 and the nuts 316 loosened. 2), the housing 302 and the stopper 352 can be positioned.
[0096]
As described above, in the mechanical shift lock device 300 as well, the switch housing 332 of the brake lamp switch 330 is mounted on the switch mounting portion 318 of the housing 302 so that the switch housing 332 is integrated with the housing 302. Unlike the lock device, there is no need to secure a space for installing the device avoiding the brake lamp, and the device can be sufficiently installed in a narrow space near the brake pedal 14.
[0097]
When replacing the brake lamp switch 330 during maintenance of the brake lamp, the bolt 314 is removed, the switch housing 332 (the brake lamp switch 330) is removed from the switch mounting portion 318, and another switch housing 332 (the brake The lamp switch 330) is fitted into the switch mounting portion 318, and the housing 302 is completely fixed to the bracket 306 again with the bolts 314 and the nuts 316, thereby completing the replacement of the brake lamp switch 330. As described above, since the brake lamp switch 330 can be easily and quickly replaced without disassembling the housing 302, even when, for example, a vehicle user requests replacement and repair of the brake lamp switch 330, it is possible to quickly respond. . Moreover, since only the brake lamp switch 330 needs to be replaced without changing the components inside the housing 302 of the mechanical shift lock device 300, the replacement cost is reduced.
[0098]

Repair work can be performed in another large work place without performing repair work in a narrow place. Therefore, the number of steps required for the repair work of the brake lamp switch 330 can be reduced.
[0099]
Further, when the brake lamp switch 330 is replaced or repaired as described above, the housing 302 does not need to be removed from the installation location near the brake pedal 14, so that the housing 302 is Since there is no need to perform positioning, the number of man-hours can be reduced in this sense as well.
[0100]
Further, in the mechanical shift lock device 300, when the depression of the brake pedal 14 (see FIG. 2) is released, the brake pedal 14 is urged by the urging force of the urging means for urging the brake pedal 14 backward. Even if it returns, the stopper 352 is interposed between the switch housing 332 and the brake pedal 14, so that the brake pedal 14 does not directly hit the switch housing 332, and The load (kinetic energy) is relieved by the stopper 352. Therefore, the durability of the brake lamp switch 330 can be improved.
[0101]
Further, in the mechanical shift lock device 300, the slider 84 is accommodated in the switch housing 332, and when the switch housing 332 is removed, the slider 84 is removed from the housing 302 together. Here, even if the slider 84 is worn due to a collision with the brake pedal 14 or the like, the slider 84 can be easily replaced together with the switch housing 332.
[0102]
The mechanical shift lock devices 10, 160, 180, 260, and 300 according to each of the above-described embodiments have the slider 54 connected to the cam 68 of the key cylinder 62 via the wire 58. The shift lever 34 is locked when the key 64 is not inserted, or when the key 64 is located at the LOCK position even when the key 64 is inserted. The present invention may be applied to a mechanical shift lock device without a lock mechanism of the shift lever 34 by 54.
[0103]
Further, in each of the above-described embodiments, the shift lever 34 is the shift operation means. However, the configuration of the shift operation means is not limited to this. For example, a dial knob type in which the shift range is changed by performing a rotation operation. May be used as the shift operation means.
[0104]
Further, in each of the above embodiments, the moving contacts 102 and 104 and the metal piece 346 are used as the moving body, and the fixed contacts 118 and 226 and the metal piece 350 are used as the moving body detection. However, the moving body detecting means detects the approaching movement of the moving body and blocks the circuit. However, the moving body detects the approaching movement of the moving body without contacting the moving body detecting means, that is, a so-called so-called "moving body". It may be configured as a proximity switch.
[0105]
【The invention's effect】
