TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mounting structure of a shift operating device in which a shift lever provided in a vehicle compartment has a boot attached thereto, and more particularly, to a shift operating device in which a pair of shift levers are fitted into an opening on the floor side and a boot is attached thereto. Regarding the structure.
[0002]
[Prior art]
A transmission and a transfer provided in a power transmission system of a vehicle are provided with a shift operation device for a shift operation and a 2WD / 4WD switching operation, and these are arranged on a floor in a front part of a vehicle compartment. Switching operability is ensured. The shift lever used in this speed change operation device is housed in a lever housing frame provided on the floor side, usually a lever housing frame formed on a console box, and is often arranged to protrude above the floor from the same portion. In this case, to prevent the shift lever from interfering with the lever housing frame, the shift lever swings in the lever housing frame due to the switching operation, and furthermore, swings largely due to torque fluctuation during engine driving. The lever housing frame has a relatively large opening. A flexible shift lever boot is attached to such an opening, thereby covering the opening and improving the appearance of the portion.
[0003]
Here, the shift lever boot has its central apex attached to the shift lever without displacement, and its skirt is supported by an annular boot attachment portion at the periphery of the opening, and the body made of a flexible material is bent, so that the shift lever boot is bent. The swing operation has been simplified.
By the way, there is a transmission and a pair of transfer shift levers arranged side by side in a lever housing frame. In this case, as shown in FIG. 7, each opening 100 holding the swinging areas a and b of the first shift lever 101 and the second shift lever 102 is a lever housing frame (not shown) on the floor of the passenger compartment. Are formed side by side in the vehicle width direction X.
[0004]
Each of the openings 100 has a flange-shaped boot mounting portion 103, 104 made of a thin steel plate formed at a peripheral edge thereof. A boot attachment part 107 is formed. Here, hem portions of both boots 105 and 106, which are opposed to the periphery of the opening, are coupled to the boot mounting portions 103 and 104 at the periphery of the opening. The opposing parts of each hem are joined together. As a result, the boots 105 and 106 are securely supported by the lever accommodating frame (not shown), and the swinging regions a and b of the shift levers 101 and 102 are bent by bending the body made of a flexible material. In addition to allowing the swing operation, the appearance of both opening portions can be kept good.
An example of a conventional shift operating device having a shift lever boot is disclosed in Japanese Utility Model Laid-Open Publication No. 64-33432.
[0005]
[Problems to be solved by the invention]
By the way, as shown in FIG. 7, when the speed change operating device is provided with a plurality of openings 100 through which the shift lever penetrates, the swing regions a and b of the first shift lever 101 and the second shift lever 102 are brought closer to each other. Even if they are arranged side by side, the width B1 in the vehicle width direction X as a whole of both openings and the relative distance between both shift levers are relatively large. For this reason, when adopting a configuration in which the gearshift operating device has a pair of openings that are close to each other, a problem is likely to occur in securing the mountability and the degree of freedom of layout of the gearshift operating device, and the entire opening may have a problem. It is desired to reduce the width B1 in the vehicle width direction X.
[0006]
In addition, a pair of shift levers and a shift lever boot covering an opening penetrating both shift levers, which are essential parts of the shift operation device, are arranged at positions that are easy for an occupant to see. It is also required to maintain good appearance.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a mounting structure of a speed change device that can improve the mountability and freedom of layout of a speed change device having an opening through which a pair of shift levers penetrate and a shift lever boot covering the opening. In addition, an object of the present invention is to provide a mounting structure for a speed change operation device capable of maintaining a good external appearance.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, an opening formed in a lever accommodating frame of a floor and a pair of shift levers respectively fitted to be able to swing is formed in the lever accommodating frame, and A boot coupling frame in which the hem of the first boot attached to one of the pair of shift levers and the second boot attached to the other are coupled to a portion facing the periphery of the opening; At the upper and lower ends of the hem portions of the first and second boots, which are loosely fitted to each other, a connecting stitch portion for sewing each other is provided, and a thin plate material is attached to a bag-like portion surrounded by both stitch portions. And a coupling part .
Here, since the pair of shift levers are fitted into the single opening, the entire shape of the opening can be made relatively small as compared with the case where the pair of openings are arranged side by side. It is possible to improve the mountability and the degree of freedom of layout of the speed change operation device having the trever boot. Furthermore, even if the coupling portion interferes with a part of the swing range of each shift lever, the swing of each shift lever is not hindered, and a part of the swing range of each shift lever is shifted. The opening can be overlapped in a range that does not cause trouble, and the overall shape of the opening can be set relatively small from these points as well, so that the mountability and the layout flexibility of the speed change operation device can be improved. Further, since the connecting portion has a thin plate material, for example, a thin sheet material made of resin enhances the bending rigidity in the vertical direction of the connecting portion, and can reliably prevent the hanging portion from sagging, thereby improving the appearance of the shift lever boot. In this case, there is no hindrance to the swing operation of each shift lever.
[0008]
According to the second aspect of the present invention, an opening formed in the lever accommodating frame on the floor, and a pair of shift levers are respectively swingably fitted thereto, and formed in the lever accommodating frame and attached to one of the pair of shift levers. A boot coupling frame in which the hem of the first boot attached and the hem of the second boot attached to the other are coupled to a portion facing the periphery of the opening, and the first boot and the first boot loosely fitted in the center of the opening. And a reinforcing portion provided with a plurality of connecting stitch portions sewn in the horizontal direction long between the upper end and the lower end of the opposing hem portions of the two boots.
In this case, the reinforcing portion reinforces the rigidity of the connecting portion in the vertical direction, prevents the portion from sagging, and can maintain a good appearance of the shift lever boot, and at this time, the swing operation of each shift lever can be performed. There is no hindrance.

First and second shift levers 2 and 3 are swingably fitted into the opening H, and a shift lever boot having the first and second shift levers 2 and 3 penetrated into a boot coupling frame 7 therearound. 1 is attached. Here, the shift lever boot 1 is formed so as to cover the opening H, and a skirt c of the shift lever boot is covered with a rectangular outer frame 9 supported by the console box 4.
The first shift lever 2 swings within the range of the maximum swing width La in the vehicle width direction X as shown in FIG. 2, whereby the first shift lever 2 retreats five forward steps shown in FIGS. 5A and 5B. A switching operation of a transmission (not shown) capable of achieving a single-gear shift mode (gear position is indicated by a circle and shift position is indicated by characters) is performed. On the other hand, the second shift lever 3 swings within the range of the maximum swing width Lb in the vehicle width direction X as shown in FIG. 2, and the two-wheel drive (2H) .4 shown in FIGS. 5 (a) and 5 (b). A transfer (not shown) switching operation capable of achieving the driving high / low (4H / 4L) switching mode (the switching position is indicated by a circle and the drive system display is indicated by characters) is performed.
[0012]
The boot coupling frame 7 has a rectangular frame portion 701 in plan view (see FIGS. 5A and 5B), and a connecting piece 702 (see FIG. 5) that extends from the square of the rectangular frame portion 701 and is screwed to the base frame 6. 2). The rectangular frame portion 701 is arranged so as to surround the rectangular opening H located at the upper part of the accommodation room A, and the skirt portion c of the shift lever boot 1 is externally fitted to the outer peripheral surface of the rectangular opening H and is integrally connected.
As shown in FIGS. 1 to 3, the shift lever boot 1 has a configuration in which a first boot 11 attached to the first shift lever 2 and a second boot 12 attached to the second shift lever 3 are integrated by sewing. take. That is, each of the first and second boots 11 and 12 is formed by sewing each side edge portion (a part of which is indicated by the symbol f in FIG. 3) of four vertically elongated substantially triangular synthetic leather pieces. It is formed in a pyramid shape, each apex d (see FIG. 1) is connected to each lever, a skirt-shaped body e is provided with sufficient flexibility, and a skirt c is fixed to a rectangular frame 701. You.
[0013]
Here, each of the boots 11 and 12 has four hem portions c formed as lower ends of the above-described substantially triangular synthetic leather pieces, and among them, one hem portion c facing each other is disposed at the center of the opening H. Then, the remaining three hem portions c are externally fitted to the outer peripheral surface of the rectangular frame portion 701. That is, the remaining three skirts c of the first and second boots 11 and 12 other than the skirts c opposed to each other are externally fitted to the outer circumferential surface of the rectangular frame portion 701, and are then fastened to the outer circumferential surface (not shown). It is fixed by a fixing means such as an attached band or a plurality of screws.
[0014]
On the other hand, each of the hem portions c of the first and second boots 11 and 12 facing each other is integrated by sewing to form a joint portion 13. Note that the shifting swing area a1 of the first shift lever 2 and the switching swing area b1 of the second shift lever 3 of the shift operating device shown in FIG. 1 are as shown in FIGS. 5 (a) and 5 (b). In addition, it is set so that each switching operation slightly interferes with the mutually opposite area within a possible range. For this reason, here, the connecting portion 13 of the first and second boots 11 and 12 is located substantially at the center of the opening H, at a portion where the shift rocking region a1 and the switching rocking region b1 overlap with each other. It is arranged in a floating state.
[0015]
As shown in FIGS. 2 to 4, the coupling portion 13 is provided with a connection stitching portion 131 at an upper end of each of the hem portions c of the first and second boots 11 and 12, and a stitching portion for binding at a lower end and both side ends. 132 is provided, and the thin plate member 14 forming a reinforcing portion is attached to a bag-like portion surrounded by the both stitching portions 131 and 132. The thin plate member 14 is a thin resin plate, and is provided so as to cross the center of the opening H in a vertical direction. In particular, the thin plate material 14 as a whole has a shape and a shape so as to secure sufficient vertical bending rigidity with respect to its own weight W and maintain sufficient flexibility with respect to a horizontal load P as the entire joint portion 13. The thickness, material and the like are appropriately selected and used.
[0016]
In a case where such a mounting structure of the shift operating device having the opening H penetrating the pair of shift levers 2 and 3 and the shift lever boot 1 covering the opening is used, the first shift lever 2 is configured as shown in FIG. It is assumed that the switching operation is performed in the shift mode of five forward steps and one reverse step shown in (b). At this time, as shown in FIG. 5A, it is assumed that the first shift lever 2 is operated to perform a shift operation within the shift range a1 for shifting, and abuts on the coupling portion 13 to apply the load P1. At this time, the connecting portion 13 provided with the thin plate member 14 is held in a floating state, and is relatively small except for the bending rigidity in the vertical direction, and is bent and deformed by the load P1 toward the switching swing area b1. In addition, the swing operation of the first shift lever 2 does not give an uncomfortable feeling. Similarly, it is assumed that the second shift lever 3 is shifted in the switching swing range b1 as shown in FIG. 5B, and abuts on the coupling portion 13 to apply the load P2. At this time, the connecting portion 13 provided with the thin plate member 14 is flexed and deformed toward the speed change swing area a1, so that the swing operation of the second shift lever 3 does not give an unnatural feeling.
[0017]
Moreover, the shift lever boot 1 has flexibility since the connecting portion 13 is formed by sewing a hem portion c made of a synthetic leather, and although the shift lever boot 1 is liable to be sagged and deformed by its own weight W. Here, since only the bending rigidity in the vertical direction is enhanced by the thin plate material 14, it is possible to reliably prevent the same portion from sagging under its own weight W and prevent dust and the like from adhering to the sagged portion. The external appearance around the connecting portion 13 of the boot 1 can be favorably maintained for a long time.
[0018]
The connecting portion 13 of the shift lever boot 1 shown in FIG. 1 is formed by sewing hem portions c of the first and second boots 11 and 12 which are made of synthetic leather and facing each other. Is attached, thereby increasing the bending rigidity in the up-down direction of the connecting portion 13. However, a configuration shown in FIG. 6 may be used instead. The connecting portion 13a of the shift lever boot 1 shown in FIG. 6 is formed by sewing hem portions c of the first and second boots 11 and 12 which are made of synthetic leather and facing each other. In this case, in particular, the opposing hem portions c of the first and second boots 11 and 12 sequentially include a plurality of connecting stitching portions 131a, 131b, and 131c 131d that are stitched horizontally longer from the upper end toward the lower end. The plurality of connection stitching portions are provided in parallel, and the entirety of the plurality of connection stitching portions is configured to form a reinforcing portion 14 a for enhancing the bending rigidity of the connecting portion 13 in the vertical direction.
Also in this case, the connecting portion 13 provided with the reinforcing portion 14a including a plurality of connecting stitching portions can obtain the same operation and effect as the connecting portion 13 provided with the reinforcing portion 14 of FIG. The configuration can be simplified.
[0019]
In the above-described process, the shift lever boot 1 of FIG. 1 is formed by connecting the first and second boots 11 and 12 made of synthetic leather to each other. The present invention may be applied to (not shown). The shift lever boot in this case is integrally formed with the hem portions of the rubber-molded first and second boots facing each other as a connecting portion. In particular, the connecting portion has a cross section to enhance bending rigidity in the vertical direction. Is formed into a vertically long rectangular cross-sectional shape. Also in this case, even if the first and second shift levers 2 and 3 come into contact with the rubber-molded connecting portion, the swinging operation does not give a sense of incongruity, and the connecting portion sags and the part where the sagging occurs. Adhesion of dust and the like can be reliably prevented, and the appearance of the shift lever boot can be favorably retained over a long period of time.
[0020]
【The invention's effect】
As described above, according to the first aspect of the present invention, the entire shape of the opening and the shift lever boot that bears the opening can be made relatively small, and the mountability and layout of the shift operating device having such an opening and the shift lever boot can be made. Degree of freedom can be improved. Furthermore, even if the coupling portion interferes with a part of the swing range of each shift lever, the swing of each shift lever is not hindered, and a part of the swing range of each shift lever is shifted. Can be superimposed within a range that does not hinder the transmission, and from these points, the entire shape of the opening can be set relatively small, and the mountability and layout flexibility of the speed change operation device can be improved. Furthermore, since the connecting portion has a thin plate material, for example, a thin sheet material made of resin strengthens the bending rigidity in the vertical direction of the connecting portion, and can reliably prevent the hanging portion from sagging, thereby improving the appearance of the shift lever boot in appearance. In this case, there is no hindrance to the swing operation of each shift lever.
[0021]
According to the second aspect of the present invention, in the mounting structure for the speed change operating device according to the first aspect, since the connecting portion is provided with a reinforcing portion, it is possible to prevent the connecting portion from hanging down, and to improve the appearance of the shift lever boot for a long time. , And at this time, the connecting portion can be bent and deformed, so that there is no hindrance to the swing operation of each shift lever.
