On the other hand, the inventions disclosed in Patent Documents 2 and 3 are both configured to be universally mounted on a shaft of a shift lever having various thicknesses and cross-sectional shapes. However, in order to realize the operability and stability at the time of mounting, a non-uniform enormous portion is formed at the connecting portion between the shaft of the shift lever and the shift knob.
In this case, even if the decoration of the shift knob itself is high, there is a sense of incongruity because the shift knob is an aftermarket part in the form of the connection part, that is, there is no sense of unity with other genuine parts, and continuous design. There was a dissatisfaction that could not satisfy the point of realizing a more complete decoration by using aftermarket parts.
In particular, when the shape of the shift knob supplied as an aftermarket part is an elongated rod, the linear form of the shaft of the shift lever and the shape of the elongated rod-shaped shift knob are combined. Although it is considered preferable that the landscape can be coordinated sharply, in the case of the ideas and inventions disclosed in Patent Documents 2 and 3, it is difficult to sharpen the form of the entire shift lever.
Furthermore, there are some shift knobs that are aftermarket parts that can be screwed to the mounting target and can be replaced at any time according to preference. In this case, it is not configured that the parts that slide up and down in the shift knob can be exchanged as desired. Moreover, even if the parts that slide up and down can be replaced, the sense of unity with the other parts is lost, and the appearance of the shift knob is also highly aesthetic and highly decorative. There was a problem that could not be made.
That is, although the invention and the invention disclosed in Patent Documents 2 and 3 are technical contents that can improve the versatility of a specific shift knob that is an aftermarket part, the versatility of the shaft that is the mounting object is improved.

  A shift knob replacement adapter according to an embodiment of the present invention will be described in detail with reference to FIGS.

An outline of the shift knob replacement adapter according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2.
FIG. 1 is a conceptual diagram of a shift knob replacement adapter according to an embodiment of the present invention. FIG. 2A is a side view of a shaft and a rod to which the shift knob replacement adapter according to the embodiment of the present invention is attached. FIG. 2B is an upper inner cylinder according to the embodiment of the present invention. It is a side view of a lower inner cylinder, (c) is a side view of the outer cylinder which concerns on embodiment of this invention.
As shown in FIGS. 1 and 2, the shift knob replacement adapter 1 according to the present embodiment is covered on the upper end side of a shaft 2 of a passenger car shift lever [see FIG. A cap-like upper inner cylinder 4 that slides in the vertical direction (see FIG. 2B) and a lower inner side that is provided on the peripheral side surface of the shaft 2 on the lower side of the upper inner cylinder 4 (see FIG. 1). A cylinder 5, an engagement structure 6 constituted by the upper inner cylinder 4 and the lower inner cylinder 5, an outer cylinder 7 provided so as to cover the engagement structure 6, and an outer surface of the lower inner cylinder 5 It is comprised by the screw | thread 8 (fixed structure) which fixes the lower inner cylinder 5 and the outer cylinder 7 on the surrounding side surface of the shaft 2, tightening from the side.
Further, the upper inner cylinder 4 of the shift knob replacement adapter 1 according to the present embodiment has a shift knob fixing portion 9 for detachably installing a desired shift knob 10 supplied as an aftermarket part on the top thereof, and FIG. 1 is provided with a first engaging portion 4a for constituting the engaging structure 6 shown in FIG.
Further, the lower inner cylinder 5 of the shift knob replacement adapter 1 according to the present embodiment has a slit 5b [see FIG. 2 (b)] formed from the upper end side to the lower end side of the peripheral side surface thereof, and FIG. The engagement structure 6 shown in FIG. 6 is provided, and the second engagement portion 5a that engages with the first engagement portion 4a described above is provided.

In the shift knob replacement adapter 1 according to the present embodiment, the shapes of the first engaging portion 4a and the second engaging portion 5a forming the engaging structure 6 do not have to be particularly limited. And what was formed in the T-shape when the cylindrical surrounding surface was expand | deployed as shown in FIG.2 (b) can be used.
In the shift knob replacement adapter 1 according to the present embodiment, since the upper inner cylinder 4 needs to slide in the extending direction of the shaft 2, both the first engagement portion 4 a and the second engagement portion 5 a are connected to the shaft 2. It is necessary to provide the side P formed in parallel with the extending direction of [see FIG. 2 (b)].
On the other hand, when the upper inner cylinder 4 is slid upward in the extending direction of the shaft 2, it is necessary to prevent the upper inner cylinder 4 from coming off from the shaft 2 and coming off. Since it is necessary to regulate the operation when sliding downward in the direction, it is necessary to have a pair of sides Q ₁ and Q ₂ arranged orthogonal to the side P [FIG. )]. That is, the sliding operation of the upper inner cylinder 4 can be restricted by providing the sides Q ₁ and Q ₂ at both ends in the vertical direction of the side P.
That is, the upper inner cylinder 4 and the lower inner cylinder 5 according to the present embodiment both include the side P and the sides Q ₁ and Q ₂ , and the engagement structure 6 including these is formed, so that the upper inner cylinder is formed. When the 4 slides upward on the peripheral side surface of the shaft 2, the effect of preventing the upper inner cylinder 4 from coming off the shaft 2 and coming off is exhibited. Further, when the upper inner cylinder 4 slides downward on the peripheral side surface of the shaft 2, the effect of stopping the sliding of the upper inner cylinder 4 at a desired position is exhibited.
The shape having the side P and the pair of sides Q ₁ and Q ₂ as described above is the first engaging portion 4a and the second engaging portion 5a having a planar shape T shape.

Here, the sliding operation of the engaging structure 6 and the upper inner cylinder 4 will be described with reference to FIG.
FIG. 3A is a side view showing a state where the upper inner cylinder according to the embodiment of the present invention is slid upward, and FIG. 3B is a side view showing a state where the upper inner cylinder is slid downward in FIG. It is. The same parts as those described in FIGS. 1 and 2 are denoted by the same reference numerals, and description of the configuration is omitted. In FIG. 3, the description of the shaft 2 to which the upper inner cylinder 4 and the lower inner cylinder 5 are attached is omitted.
As shown in FIG. 3A, when the upper inner cylinder 4 is slid upward, the T-shaped first engaging portion 4a and the second engaging portion of the upper inner cylinder 4 and the lower inner cylinder 5 are provided. meshes projections each other extending in the horizontal direction at 5a, i.e., in the side Q ₁ in the first engagement portion 4a and the side Q ₁ in the second engagement portion 5a is in contact with each other, the first engagement portion The slide operation 4a is restricted.
On the other hand, as shown in FIG. 3B, when the upper inner cylinder 4 is slid downward, the T-shaped first engagement portions 4a and second engagement portions of the upper inner cylinder 4 and the lower inner cylinder 5 are provided. to each side Q ₂ to which is formed at the base portion of the engagement portion 5a, the first engagement portion 4a, the edge of the second engagement portion 5a (T-shaped horizontal axis portion) abuts the upper The sliding operation of the inner cylinder 4 is restricted.
As a result, as shown in FIG. 3, the upper inner cylinder 4 can slide and move by the amount indicated by the symbol H in FIG. 3. The range indicated by the symbol H is the movable range of the upper inner cylinder 4. With this movement, the rod 3 shown in FIG. 2 (a) is pushed down vertically as necessary.

When the rod 3 itself is urged so as to always protrude upward from the upper end of the shaft 2 by some mechanism, it is only necessary to cover the upper inner cylinder 4 on the top (upper end) of the shaft 2. The upper inner cylinder 4 is always pushed up by the top of the rod 3, and the upper inner cylinder 4 is maintained in the state shown in FIG.
On the other hand, if the force to push the rod 3 upward is insufficient, the rod 3 is unintentionally pushed down due to the load of the upper inner cylinder 4 and the ride shift is performed when the vehicle is driven. The lever may be misoperated, which is extremely dangerous.
In such a case, an elastic material (not shown) made of, for example, a coil spring is provided around the rod 3 led out from the upper end portion of the shaft 2, and the shift knob 10 attached to the shift knob fixing portion 9 is provided. Unless the user intentionally depresses (see FIG. 1), the upper inner cylinder 4 is always urged to be pushed upward by an elastic material so that the upper inner cylinder 4 does not slide downward. There is a need.
According to the structure as described above, the top portion of the rod 3 led out from the upper end portion of the shaft 2 can be pushed down by the upper inner cylinder 4 only when necessary while maintaining the linear form of the shaft 2.

Next, a fixing structure of the shift knob replacement adapter 1 according to the present embodiment will be described with reference to FIGS.
In the shift knob replacement adapter 1 according to the present embodiment, as shown in FIG. 2B, the lower inner cylinder 5 includes a slit 5b. Then, after such a lower inner cylinder 5 is provided on the peripheral side surface of the shaft 2, the outer cylinder 7 is covered thereon, and a screw 8 is screwed into the screw hole 7 a, thereby providing a screw 8. The lower inner cylinder 5 is pressed and contracted from the outer surface toward the center side by the tip. That is, the lower inner cylinder 5 is fastened from the outer peripheral side surface by the screw 8 and is in close contact with the peripheral side surface of the shaft 2, and the lower inner cylinder 5 is fixed on the peripheral side surface of the shaft 2.
In this case, as shown in FIG. 3, even if the upper inner cylinder 4 is slid swiftly downward in the extending direction of the shaft 2, the lower inner cylinder 5 is displaced or rotated in the circumferential direction of the shaft 2. There is little fear. As a result, the upper inner cylinder 4 can be precisely slid only in the vertical direction while preventing the upper inner cylinder 4 from rotating in the circumferential direction.
Moreover, as the screw 8 screwed into the screw hole 7a of the outer cylinder 7, for example, by using a screw that is short and has only a shaft body that does not have an operation head, The appearance of the shift knob replacement adapter 1 according to the embodiment can be made a simple straight line that does not make the presence of the screw 8 feel.
As a result, while maintaining the shape of the shaft 2 in the riding shift lever as straight as possible, the fixing structure does not give any sense of incongruity in design, and the operation during use is a component for riding. It is possible to provide a shift knob replacement adapter 1 that is sufficiently precise to ensure the safety of the above.
In the shift knob replacement adapter 1 according to the present embodiment, a combination of the screw hole 7a formed in the outer cylinder 7 and the screw 8 screwed in the screw hole 7a is the lower inner cylinder 5. This corresponds to a fixing structure for fixing to the shaft 2.

Next, a modification of the shift knob replacement adapter 1 according to the present embodiment will be described with reference to FIG.
FIG. 4A is a conceptual diagram showing a first modification of the lower inner cylinder according to the embodiment of the present invention, and FIG. 4B is a conceptual diagram showing a second modification of the lower inner cylinder of the present invention. It is. Furthermore, (c) is a side view showing another fixing method of the lower inner cylinder of the invention. The same parts as those described in FIGS. 1 to 3 are denoted by the same reference numerals, and description of the configuration is omitted.
As a fixing structure in which the lower inner cylinder 5 is detachably fixed to the shaft 2, the following method can be considered in addition to the method using the screw 8 as described above.
For example, as shown in FIG. 4A, the shape of the outer surface of the lower inner cylinder 5A is a tapered body 5c whose diameter is reduced from the lower end side toward the upper end side, and the lower inner cylinder 5A is used as a wedge to form the outer cylinder 7 It is good also as a structure which fixes the outer cylinder 7 on the surrounding side surface of the shaft 2 from the lower inner cylinder 5A by pushing in in the hollow part from the lower end side. The fixing structure in this case is a fitting structure including the outer shape (outer side surface) of the lower inner cylinder 5 </ b> A functioning as a wedge and the inner side surface of the outer cylinder 7.
In this case, the shift knob replacement adapter according to the present embodiment eliminates the need to use the screw 8 while exhibiting the same effect as the case where the lower inner cylinder 5 is fixed using the screw 8 as described above. It has the merit that the form when 1 is attached to the shaft 2 can be made more linear.
In addition, as shown to Fig.4 (a), the thread 5d is formed in the outer surface of the taper body 5c which comprises the lower inner cylinder 5A, and the inner surface of the outer cylinder 7, and the outer surface of the taper body 5c is formed. In addition to the fitting structure as described above, the inner surface of the outer cylinder 7 may be configured to form a screwing structure. In this case, the effect of fixing the lower inner cylinder 5A by the outer cylinder 7 can be further ensured. In this case, the shift knob replacement adapter 1 with higher reliability can be provided.

Further, as shown in FIG. 4B, a thread 5d is formed on the outer side surface of the lower inner cylinder 5B and the inner side surface (not shown) of the outer cylinder 7 without forming the lower inner cylinder 5B into a tapered body 5c. After the lower inner cylinder 5B is mounted on the shaft 2, the lower inner cylinder 5B may be tightened and fixed to the shaft 2 by screwing the outer cylinder 7 on the peripheral side surface. The fixing structure in this case is a screwed structure formed by a screw thread (not shown) formed on the outer surface of the lower inner cylinder 5B and a screw thread 5d formed on the inner surface of the outer cylinder 7.
In this case, the thread-ridge dimension formed on the inner surface of the outer cylinder 7 is set slightly smaller than the thread valley-valley dimension formed on the outer surface of the lower inner cylinder 5B. Thus, when the outer cylinder 7 is screwed on the outer surface of the lower inner cylinder 5B, the effect of tightening the shaft 2 by the lower inner cylinder 5B can be exhibited. Furthermore, in this case, the valley-valley dimension at the upper end of the thread formed on the outer surface of the lower inner cylinder 5B is made the same as or slightly smaller than the thread-ridge dimension formed on the inner surface of the outer cylinder 7. Thus, the outer cylinder 7 can be securely screwed on the outer surface of the lower inner cylinder 5B.
Also in this case, as in the case of using the lower inner cylinder 5A as described above, there is an advantage that the form when the shift knob replacement adapter 1 is attached to the shaft 2 can be made more linear.

Further, as another modification of the lower inner cylinder 5 shown in FIGS. 1 to 3, a step 11 is formed at the lower end of the lower inner cylinder 5 as shown in FIG. The outer cylinder 7 is locked by a step 11 formed on the lower inner cylinder 5 when the outer cylinder 7 is installed on the outer side surface of 5, and does not slide vertically below the step 11. It is good.
In this case, when the shift knob replacement adapter 1 according to the present embodiment is attached to the peripheral side surface of the shaft 2, the outer cylinder 7 can be easily positioned on the lower inner cylinder 5.

In the shift knob replacement adapter 1 according to the present embodiment, as shown in FIGS. 1 to 3, the shift knob 10 is screwed to the shift knob fixing portion 9 as an example. The method of attaching the shift knob 10 to the portion 9 need not be specified as screwing, and a method other than screwing may be employed.
More specifically, the shift knob 10 is attached so that the shift knob 10 does not rotate in the circumferential direction when the shift lever 10 is operated by the shift knob 10, and the shift knob 10 can be easily attached according to the purpose after the shift knob 10 is attached. Any attachment method may be adopted as long as it can be exchanged.
In particular, when the shift knob fixing portion 9 is a screw and the diameter of the screw does not correspond to the diameter of the screw hole formed in the shift knob 10 to be attached, for example, a caliber screw adapter is used. Thus, it becomes possible to attach the desired shift knob 10 by changing the diameter of the screw that is the shift knob fixing portion 9.

According to the shift knob replacement adapter 1 according to this embodiment, the shaft of the passenger car shift lever to which the shift knob replacement adapter 1 is attached can be formed in a linear form. As a result, the decorativeness and texture of the shift knob 10 having a desired shape provided on the top of the upper inner cylinder 4 via the shift knob fixing portion 9 can be further enhanced.
Further, the shift knob replacement adapter 1 according to the present embodiment has the above-described linear and simple form, while the lower inner cylinder 5 is in close contact with the peripheral side surface of the shaft 2 and the vertical direction of the upper inner cylinder 4 Since the movement of the upper inner cylinder 4 in the circumferential direction of the shaft 2 can be prevented at the same time, the safety during operation of the shift knob 10 can be made extremely high.
Further, the first engagement portion 4a and the second engagement portion 5a formed on the upper inner cylinder 4 and the lower inner cylinder 5 respectively form the engagement structure 6 so that the upper inner cylinder 4 is moved upward. When sliding, it is possible to reliably prevent the upper inner cylinder 4 from coming off from the upper end of the lower inner cylinder 5 of the passenger car shift lever. Therefore, the shift knob replacement adapter 1 with extremely high safety can be provided also in this respect.
In addition, when the shift knob replacement adapter 1 according to the present embodiment is used, it can be easily replaced with another desired shift knob 10 at any time after the shift knob replacement adapter 1 is mounted on the shaft 2. That is, the shift knob replacement adapter 1 according to the present embodiment has not only high versatility for mounting the passenger car shift lever of various specifications to the shaft 2, but also the shift knob after the shift knob is mounted. It has a unique function of high versatility for 10 exchanges.
Therefore, according to the shift knob replacement adapter 1 according to the present embodiment, it is practical, high in aesthetics and hobby for car owners who enjoy using aftermarket parts to arrange vehicles with high taste. It is possible to provide the adapter 1 for exchanging the shift knob with extremely high performance.

  This is a shift knob replacement adapter for detachably attaching a shift knob for retrofitting to a shift lever of an automatic transmission in a passenger car, and can be used in the fields related to transportation and entertainment.
