Description

  The present invention relates to a function expansion mechanism for a handle bar, preferably applied to, for example, a scooter type motorcycle.

When using a motorcycle, various information terminal devices such as a navigation system and an in-vehicle device for an electronic toll collection system are installed. Needless to say, these information terminal devices are preferably provided in the field of view of the rider, and are specifically attached using a handlebar or the like. Looking at so-called smartphones, which are one of such information terminal devices, the diversification and enhancement of their functions is remarkable. For this reason, smartphones are also mounted around the handlebars of motorcycles. When many information terminal devices are mounted in this way, it is impossible to secure a space for mounting on the handlebar itself. For this reason, in order to mount these information terminal devices, a mounting bar is separately attached to the handle bar in a brace shape to obtain a mounting space for these information terminal devices.
By the way, in a scooter type motorcycle, in many cases, even when a pipe is used as a strength member, the handle is often designed so as to cover it with a plastic cover or the like. For this reason, in a scooter type motorcycle, the conventional method of providing a brace-like member on the assumption that the pipe handle is exposed cannot be adopted, and the information equipment terminal cannot be installed at a preferred position. was there.

For this reason, the present applicant has already used a mirror mounting bolt hole in an exposed state to provide a brace-like shape even in a motorcycle having a covered handle where the handlebar pipe is not exposed. We have proposed a new motorcycle handlebar function expansion mechanism that can add a utility bar as an auxiliary member, and the actual product is well received on the market.
On the other hand, however, the following problems were pointed out when looking at the situation where devices such as information terminals were installed around the handlebars. In other words, the safety indicator of the speedometer, etc. in the situation where the rider gets on the vehicle, especially the shape around the steering wheel, the arrangement of the safety indicator such as the speedometer, and the shape and dimensions of the information terminal device attached by the user. Problems have been pointed out, such as the devices becoming difficult to see and the location of information terminal devices being too close.
Further, depending on the type of vehicle, there are some that cannot use the mirror mounting bolt hole due to the positional relationship with the switch holder having various switches.

Japanese Utility Model Publication No. 6-27476

  The present invention has been made in consideration of such various backgrounds, and when an information terminal device is retrofitted on a motorcycle, it makes the security display device such as a speedometer difficult to see. We propose a new function extension mechanism for motorcycle handlebars that is designed to prevent this.

  The function extension mechanism of the handlebar for a motorcycle according to claim 1 is provided with a utility bar along the handlebar for the motorcycle, and the structure for fixing the utility bar to the handlebar is as follows. Of the fixing members of the functional member bracket provided near both ends of the handlebar, the fixing member is fixed using a fixing member located below the center of the handlebar in the cross section direction of the handlebar. It is.

The function extension mechanism of the handlebar for a motorcycle according to claim 2 is characterized in that, in addition to the requirement of the claim 1, the utility bar has a diameter that is the same as that of the handlebar of the motorcycle in its entire width or part. The adapter brackets are provided at both ends, and are attached to the functional member bracket via the adapter brackets.
The above problems can be solved by using the configuration of the invention described in each of the claims as a means.

  First, according to the first aspect of the present invention, among the fixing members of the functional member bracket that are exposed to the outside in most models, the fixing member that is located below the center of the handle bar in the cross-sectional direction of the handle bar is used. As a result, the utility bar can be installed in front of the handle (rear) and close to the bottom, and even if an information terminal device is mounted on this, the speedometer It will not be difficult to see the security display device. In addition, such a utility bar is added in the form of a brace, so that the strength of the handle itself can be improved.

  According to the second aspect of the present invention, the utility bar has a diameter that is the same as that of a generally used motorcycle handlebar in the entire width or a part of the utility bar. The clamp member can be used as it is.

It is a perspective view which shows the use condition of this invention. It is an exploded perspective view same as the above. It is sectional drawing which shows a functional member bracket periphery, and sectional drawing which shows the other Example of a functional member bracket. An overhead view (a) showing the vicinity of the utility bar in the function expansion mechanism of the present invention as seen from the rider, and an overhead view (b) showing a situation that obstructs the field of view of the security display device by the utility bar when the method of the present invention is not adopted (b) ).

  The mode for carrying out the present invention includes an embodiment described below, and includes various improved embodiments based on this technical idea.

Hereinafter, the present invention will be specifically described based on illustrated embodiments.
First, FIG. 1 shows a part of a motorcycle M to which the present invention is applied, and includes a function expansion mechanism U (hereinafter referred to as a function expansion mechanism U) for a handlebar according to the present invention. That is, the function expansion mechanism U of the present invention attaches the utility bar 15 to the periphery of the handle bar 1 using the adapter bracket 14 so that the information terminal device 2 can be attached via the terminal device holder 3 and the handle bar 1 is attached. The purpose is to expand the function of the bar 1. The method for attaching the function expansion mechanism U will be described in detail later.
Further, the peripheral equipment of the handle bar 1 will be described. The handle bar 1 includes various functional members 5 near both ends thereof. Specifically, the functional member 5 is a collective term for various switches and the like, a lever holder that supports the brake lever 51, and the like, and in many cases, a light alloy die-cast configuration is used to ensure the necessary strength. There are many cases. The functional mirror 5 may be screwed with a rearview mirror 6.
In addition, a meter panel 7 may be disposed at the center of the handle bar 1 as an example.
In this specification, the front (front) means the direction of the front of the rider in the driving posture riding the motorcycle M, and the rear (rear) and the left / right direction (left / right) are also viewed from the rider. Direction.

The function expansion mechanism U of the present invention will be described in detail below. First, the configuration around the handle of the motorcycle M will be described.
First, as shown in FIGS. 1 and 2, the handle bar 1 has a handle bar pipe 10 which is a strength member as a basic skeleton member, which is directly or indirectly attached to a steering shaft by bolts or the like as appropriate. While being fixed, the grip 11 is provided in the right and left ends. Normally, the grip 11 has a throttle grip on the right side.
A functional member bracket 12 which is a part of the constituent members of the functional member 5 and has a certain strength is provided in an inner portion of each grip 11, that is, a portion closer to both ends (center side) of the handle bar 1.
In this embodiment, the holder of the brake lever 51 is used as the functional member bracket 12, and in many cases, it is divided in the front-rear direction or the vertical direction, and the handlebar pipe 10 is divided by the divided piece 121 and the main body divided piece 122. It is attached directly to the handlebar pipe 10 so that
As an example, bolt holes 123 are formed in the divided piece 121 at two locations on the upper and lower sides. On the other hand, screw holes 124 are formed in the main body divided piece 122 at two upper and lower portions corresponding to the bolt holes 123 in the divided piece 121, and the divided piece 121 and the main body divided piece 122 are fastened by bolts 125. The main body dividing piece 122 is provided with a lever pivot 126, and the brake lever 51 is rotatably held by the lever pivot 126.

Of course, the functional member bracket 12 is in an exposed state so that this can be seen directly, and at least one bolt hole 123 in the divided piece 121 is in the cross-sectional direction of the handlebar 1 as shown in FIG. It is located below the rear part from the center of the handlebar 1 and is in a state that allows attachment of other members by being in an exposed state.
The functional member bracket 12 is a generic term for not only the holder of the brake lever 51 but also a switch holder and an independent mirror holder. In the embodiment shown in FIGS. A functional member 5 as a switch holder is provided between the holder and the holder.

  The rear-view mirror 6 may be provided on a holder or switch holder of the brake lever 51 as the functional member 5 or may be provided on a mirror holder that only holds the mirror. The functional member bracket 12 may be used.

The adapter bracket 14 is attached to the periphery of the handlebar 1 (closer to the rider) using the bolt hole 123 in the divided piece 121. The adapter bracket 14 will be described in detail below.
That is, in the embodiment shown in FIG. 1 and FIG. 2, the adapter bracket 14 is applied with a band-shaped metal material as an example, the mounting hole 140 is formed at one end, and the utility bar is mounted at the other end. A hole 142 is formed.
Of these mounting holes, the mounting hole 140 is a simple round hole, but the utility bar mounting hole 142 may be a simple round hole or a tapped screw hole.
In this embodiment, the distance between the functional member bracket 12 and the adapter bracket 14 is appropriate around the mounting hole 140 on the surface facing the divided piece 121, that is, on the contact surface side. The spacer 141 is integrally formed, and the adapter mounting hole 140 is formed at the center thereof.

By preparing the height spacer 141 as a separate member and selectively using a plurality of different height dimensions, it becomes possible to deal with a plurality of vehicle types and the rear side of the utility bar 15. It is possible to adjust the degree of overhang.
Similarly, by changing the positions of the mounting holes 140 and the utility bar mounting holes 142 or by making these holes into elongated holes, it becomes possible to cope with a plurality of vehicle types and adjust the installation state of the utility bar 15. It becomes possible.
Further, the adapter bracket 14 may be formed into a non-flat shape by appropriately bending the adapter bracket 14 according to the shape of the functional member bracket 12 to which the adapter bracket 14 is attached and the positional relationship between the left and right functional member brackets 12. Is possible.

When the adapter bracket 14 configured in this way is assembled to the functional member bracket 12, first, the lower bolt 125 is loosened and removed from the divided piece 121. Next, the adapter mounting hole 140 of the adapter bracket 14 is matched with this on the bolt hole 123 in the divided piece 121, and the bolt 125 inserted therein is screwed into the screw hole 124 in the main divided piece 122, thereby again. The handle bar pipe 10 is attached to the handle bar 1 by the divided piece 121 and the main body divided piece 122.
Depending on the height dimension of the height spacer 141, the length of the bolt 125 originally used for the functional member bracket 12 may be insufficient. In this case, a long-sized bolt 125 is prepared separately. Shall be provided.

The utility bar 15 is fixed to the adapter bracket 14 attached to the handle bar 1 as described above. The utility bar 15 and its mounting structure will be described below.
First, the configuration of the utility bar 15 will be described. The utility bar 15 is configured by fitting and fixing a pair of end pieces 152 to both ends of a brace rod 151 extending in the center along the width direction of the handle bar 1. A fixing hole 153 that receives the fixing bolt 154 is formed in the end piece 152. Of course, as described above, the end piece 152 may be a member separate from the brace rod 151 and may be press-fitted and fixed to the end of the brace rod 151. However, the end of the brace rod 151 is a so-called round shape. When the brace rod 151 is a pipe material, it may be formed by crushing it into a flat plate. Further, the fixing hole 153 may be simply provided while maintaining the diameter of the brace rod 151 so as not to be recognized as the special end piece 152.
A configuration in which the length of the utility bar 15 can be appropriately changed may be adopted. For example, a lock male screw is formed on the outer periphery of the end of the brace rod 151, a lock female screw is formed on the end piece 152, and these are screwed. As a fitting shape, it is possible to adjust the mounting positions in the left and right width directions by adjusting the twist.

  And when such a utility bar 15 is connected with respect to the adapter bracket 14, the fixing volt | bolt 154 is used. Of course, a fixing nut may be used on the opposite side of the bolt head of the fixing bolt 154, or a female screw may be engraved in the fixing hole 153 in the end piece 152. In this embodiment, the fixing bolt 154 uses a decorative washer 155 as an example in the tightening surface portion.

  With this configuration, the function expansion mechanism U having the utility bar 15 and the adapter bracket 14 as main members is formed on the handle bar 1. In the present embodiment, the brace rod 151 has the same diameter over the entire length direction, but a part of the diameter may be different. In any case, it is preferable that the size of the large-diameter portion is the diameter of the handlebar pipe 10 that is generally used in a motorcycle. In general, the dimension is Φ22.2 mm, but for heavy vehicles, Φ25.4 mm may be used, and for lightweight vehicles, Φ20 mm may be used.

In the handle bar 1 having such a function expansion mechanism U, for example, a bolt is fastened so that the terminal device holder 3 is inserted into the utility bar 15, and a so-called smartphone or the like is fixedly held therein.
As described above, according to the present invention, among the fixing members of the functional member bracket 12 exposed to the outside in most models of the motorcycle M, the position of the handle bar 1 is lower than the center of the handle bar 1 in the cross-sectional direction. The bracing-like utility bar 15 can be provided using the fixing member (bolt 125) to be used. At this time, since the brace rod 151 protrudes backward and is further located below the functional member bracket 12, As shown in FIG. 4A, the information terminal device 2 and the like can be added without making the utility bar 15 difficult to see the security display device such as the meter panel 7 or the like.
Incidentally, what is shown in FIG. 4 (b) is the situation around the utility bar 15 'when the method of the present invention is not employed. Since this utility bar 15 'is provided at substantially the same height as the grip 11' without protruding backward, the rider cannot fully see the instrument panel 7 'by this utility bar 15'. I'm stuck.

Further, as an incidental effect, such a utility bar 15 is added in a so-called brace shape, so that the strength of the handle bar 1 itself can be improved.
In addition, the utility bar 15 has a diameter that is the same as that of the handle bar 2 of the motorcycle M that is generally used in the entire width or a part of the utility bar 15, and the clamp member of the terminal device holder 3 that has already been widely used can be used as it is. .

Of course, in this embodiment, in order to promote functional understanding, the terminal device holder 3 has a minimum shape configuration capable of holding the information terminal device 2, but in consideration of use in the motorcycle M or the like, the information terminal device It is preferable to further use a cover or the like for protecting 2.
In addition to attaching the information terminal device 2 using the function expansion mechanism U, the embodiment shown in FIG. 1 shows a state in which a so-called retrofit helmet holder 16 is attached to the utility bar 15.

[Other Embodiments]
The present invention is based on the embodiment described above as one basic technical idea, but the following modifications can be considered.
First, in the basic embodiment described above, the functional member bracket 12 is formed by combining two members of the divided piece 121 and the main body divided piece 122. However, as shown in FIG. Can be configured as a so-called saddle type in which the handlebar pipe 10 is inserted.
Further, in the basic embodiment described above, the functional member bracket 12 is constituted by the divided piece 121 and the main body divided piece 122 that are divided in the front-rear direction, but the divided piece 121 that is divided in the vertical direction as shown in FIG. The main body divided piece 122 may be used.
