Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a workbench provided on an annular handle of a vehicle, for example.

[0002]

2. Description of the Related Art Conventionally, regarding the structure and usage of a table (workbench) for attaching a handle, the inclination of the handle is utilized as in JP-A-7-20571 and JP-A-2001-1840. The workbench main body is hung from the peripheral edge of the handle with a hook or the like and placed on the upper surface of the handle, or a band or the like as a suspending means is wrapped around the upper peripheral edge of the handle as in JP 2001-71818 A, for example. There is something that can be fixed to the handle.

[0003]

However, these have the following problems.

That is, when the workbench is hung from above the periphery of the handle with a hook or the like and the workbench (table) is placed on the upper surface of the handle, the fixed state becomes unstable depending on the shape and diameter of the handle. Or, if an action (force) from below or from the side is applied in some way, the suspending action becomes incomplete and the handle is immediately disengaged. This is because the driver's seat is relatively narrow, so that a part of the user's body easily contacts the workbench (table), and at that time, the center of gravity of the object placed on the workbench (table) is This is because, as a result of being biased to either the left or the right side, the balance of the hanging portion is often lost.

Further, when fixing to a handle using a fixing means such as a band, the shape of the operation transmitting portion at the center of the handle differs depending on the manufacturer, so it is necessary to adjust the mounting position of the band for each handle each time the vehicle type etc. changes. There is
It is difficult to attach depending on the shape of the operation transmission part in the center of the handle. In addition, at the time of mounting, a mounting work and mounting parts are required for each mounting (fixing) part on the upper part of the handle periphery or the center part of the handle, which complicates the mechanism and increases the number of parts.

Further, in any of the above cases, since the member is placed in contact with the inclined surface of the handle directly, the member comes into contact with the central operation transmission portion of the handle. In recent years, along with the modernization and high tech of vehicles, there are some vehicle models that have a mechanism such as an airbag, a shift change button, and a wiper switch in the operation transmission section at the center of the steering wheel, in addition to the buttons of the conventional alarm device, The exterior surface of these is a horizontal surface (sloping part) created by the driver's side on the periphery of the steering wheel.
It may be located above and may project.

Therefore, when the workbench is placed on the upper surface of the handle by suspending it from the upper part of the handle periphery or the operation transmitting part, the mechanism of the operation transmitting part at the center of the handle may malfunction or be damaged. It was

Further, since the installation angle of the handle, the diameter and thickness of the peripheral portion of the handle, etc. differ depending on the vehicle model, it is often difficult to make adjustments to keep the angle of the table (work table) horizontal during mounting.

The present invention has been made in view of the above conventional circumstances, and an object thereof is a handle which is securely fixed to a handle by a relatively simple method and which does not interfere with an accessory of the handle. To provide a workbench for mounting.

[0010]

According to the present invention, there is provided a work plate, a fulcrum which can be fixed at an arbitrary angle with respect to a surface of the work plate, and at least two places provided on the support, and an outer circumference of a handle. For mounting the handle, which has a fixing portion that holds a part of the portion from the outside to the inside of the handle and that fixes the lower surface of the support body and the outer end surface of the operation transmitting portion at the central portion of the handle so as to provide a gap therebetween. It relates to a workbench.

According to the present invention, the support is provided at least at two places, and a part of the outer peripheral portion of the handle is securely sandwiched from the outside of the handle toward the inside, and further, the lower surface of the support and the central portion of the handle. The operation transmitting portion is provided with a fixing portion that is fixed so as to provide a space between the outer end surface of the operation transmitting portion. Therefore, even if an external force is applied to the support body, the supporting portion does not easily come off from the handle. The support can be securely fixed to the handle regardless of the structure, and further, since the support does not come into contact with the operation transmission portion in the center of the handle, damage or malfunction due to contact is unlikely to occur.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, it is desirable that the fixing portion is annular so as to securely fix the support to the handle.

Preferred embodiments of the present invention will be described below with reference to the drawings.

In the present embodiment, the structure of the handle attachment workbench attached to the handle 15 as shown in FIG. 2 is as follows.

First, as shown in FIG. 2, a hinge 2 having an angle adjusting mechanism such as a ratchet and a lock mechanism is provided on one side of the front side of a rectangular table plate 1 and is rotatably attached to one side of a supporting plate 3. .

The support plate 3 and the table plate 1 are preferably thin and lightweight in consideration of portability, but various options are conceivable in consideration of use outdoors.

For example, a typical notebook personal computer has a continuous drive time of 5 to 7 hours, but the drive time becomes extremely short when used for communication or connected to an external device. Therefore, by providing a space for accommodating the battery inside the support plate 3 and actually accommodating the battery, the usage time can be extended.

Although it is conceivable to use the power source of the vehicle from a cigar socket or the like, considering that it is premised on use when the vehicle is stopped, in order to suppress the discharge of the vehicle battery during use of the personal computer. It is possible to perform idling. Therefore, in order to consider the environment,
A type that charges with a household power source or a type that charges while driving is desirable.

A space may be provided below the support plate 3 in consideration of installation of a connection device for a personal computer. Further, a fine heat exhaust port may be provided on the table plate 1 for exhausting heat from the personal computer, or a mesh shape may be provided.

Further, as the products already on the market, there are soft covers and hard covers for notebook computers. In the same manner as above, a space is provided between the support plate 3 and the table plate 1 to form a notebook type. A mobile device such as a personal computer may be incorporated.

For example, by protecting the periphery of the support plate 3 and the table plate 1 with a cushioning material and further attaching a fastener or a handle, it is possible to serve as a simple hard case for a personal computer. It should be noted that it may be in a form provided with a handle support rod piece for fixing the handle on the back side of the personal computer case.

Further, a cup holder, a reading light, a mobile phone holder, a palm rest and the like may be attached as a retrofit attachment.

In this embodiment, the table plate 1
The shape, material, width, length, thickness, etc. of may be freely changed as long as a predetermined effect is obtained.

Further, the shape, material, width, length, thickness and the like of the support plate 3 may be freely changed as long as it has a predetermined effect.

Also, a hinge 2 with a ratchet and lock mechanism
The shape, the material, the width, the length, the thickness, the method of attaching to the support plate 3 and the table plate 1, the attachment angle, the attachment position, etc. may be freely changed as long as there are predetermined effects.

The ratchet mechanism and the lock mechanism may be freely changed as long as they have a predetermined effect.

The work surface of the support plate 3 may be provided with a slip-prevention sheet or the like, or may be provided with a peripheral edge so that the placed object does not easily slip off the support plate 3. .

Further, it is also possible to provide depressions or holes of any shape so that objects of various shapes can be placed.

Next, as shown in FIG. 5, on the back surface of the support plate 3, there is provided a seat plate in which a spring-like spring 14 serving as a rotating means for pressing the handle fixing portion 4 against the back surface of the support plate 3 is provided. Two seats 7 are provided on the left and right in a direction orthogonal to the ratchet and the hinge 2 with a lock mechanism, and a groove 12 and a support plate 3 are provided in the center of the seat plate 7 together with the spring-like spring 14.
In the space between the back side of the rotating part 1 and a part of the relay part bar piece 6
3, the handle fixing portion 4 including the relay portion rod piece 6 and the handle supporting portion rod piece 5 is fixed so that the handle fixing portion 4 can be rotated so as to be pressed from the outer side to the inner side of the support plate 3.

In this embodiment, the shape, material, width, length, thickness, mounting position of the seat plate 7, the number of mounting points, the mounting method, etc. of the seat plate 7 are as long as there are predetermined effects. You can change it freely.

Further, the position, shape, depth, width, diameter, length, number of installations, installation method, etc. of the groove portion 12 may be freely changed as long as there is a predetermined effect.

Further, the shape, material, width, length, thickness, diameter and the like of the relay rod piece 6 may be freely changed as long as it has a predetermined effect.

Further, the shape and material of the handle support rod piece 5,
The width, length, thickness, diameter, etc. may be freely changed as long as a predetermined effect is obtained.

Further, the size, length, shape, diameter, width, number of installations of the spring-shaped springs 14 housed in the rotating portion 13,
The installation method and the like may be freely changed as long as there is a predetermined effect.

Further, the rotating means is not limited to the one using the spring 14 and may be freely changed as long as it has a predetermined effect.

The handle fixing portion 4 consisting of the relay portion rod piece 6 and the handle supporting portion rod piece 5 is seated by the rotating means by the spring-like spring 14 provided in the rotating portion 13 in the seat plate 7. A pivoting moment from the outside to the inside of the support body 3 is generated around the groove portions 12 at the two fixed locations on the back surface of the plate 7, and is stationary at a position where it is pressed against the back surface of the support plate 3. .

In the present embodiment, the strength of the turning moment in the turning portion 13 has a certain effect if it has a predetermined effect.
You can change it freely.

Further, the accommodation position or form of the handle fixing portion 4 when the workbench is not used may be freely changed as long as it has a predetermined effect.

Next, when using this embodiment, the support plate 3 and the table plate 1 folded as shown in FIG.
Hold by hand and hold the handle fixing part 4 including the relay part rod piece 6 on the back surface of the support plate 3 and the handle support rod piece 5 from the inside of the support body 3 to the outside on the handle 15 to be placed. Push it to the left and right while rotating it toward you.

At this time, the central portion of the back surface (inside) of the support plate 3 is acted on the relay portion rod piece 6 and the handle support rod piece 5 by the action of the spring-like spring 14 provided in the groove portion 12 of the seat plate 7.
There is a constant turning moment that always tries to return to.

Next, as shown in FIG. 1 and FIG. 4, the user handles the peripheral portion 8 of the handle 15 substantially above the center of the handle 15.
The handle support rod piece 5 is opened wider than the diameter of the handle support rod piece 5, and the annular portion 17 sandwiches the handle peripheral edge portion 8 with the handle peripheral edge portion 8 so that both hands are released. The annular portion 17 has a spring-shaped spring 14 serving as a rotating means toward the center of the handle 15.
A strong turning moment to return to the original state is generated through the relay portion bar piece 6, and this turning moment ensures that the annular portion 17 of the handle support rod piece 5 holds the handle 15 to hold the support plate 3 at the handle. Firmly fixed to 15.

When the diameter of the handle 15 is large,
It goes without saying that the opening angle of the handle fixing portion 4 to the outside becomes large, and when the diameter is small, the opening angle becomes small.

The handle support rod 5 has an annular portion 17 having an appropriate curved portion, and has a shape in which the entrance is wide but gradually narrows toward the tip, so that the diameter of the handle 15 is small. Also, it can be fixed at a position according to the thickness of the handle peripheral portion 8 and the like, and can be fixed regardless of the conditions such as the thickness of the handle peripheral portion 8.

Further, since the shape of the handle peripheral portion 8 is an annular shape, when the support plate 3 is attached, the handle support rod piece 5 is attached.
The annular portion 17 of the spring-shaped spring 1 serves as a rotating means.
Due to the turning moment of 4, a part of the circumference of the handle peripheral portion 8 is gradually and diagonally sandwiched in the left and right directions. Further, the turning moment is evenly related to support the handle at two locations. 4 together with the annular part 17 of the rod piece 5,
The curved portion of the portion serves as means for firmly fixing the support plate 3 to the handle peripheral portion 8.

Further, since this is the sandwiching or grasping by the spring-shaped spring 14 which is the rotating means, even after the support plate 3 is once fixed, the user may, if necessary, make the annular shape of the handle support rod piece 5. It is possible to freely adjust the attachment angle in the clockwise or counterclockwise direction with respect to the handle 15 after opening and holding the portion 17 and releasing the fixation.

In addition, depending on the conditions such as the mounting state of the support plate 3 and the table plate 1, the support plate 3 can be used by adjusting the angle to 90 degrees.

At this time, the support plate 3 is fixed at a proper distance from the operation transmitting portion 9 at the center of the handle, and this distance (interval) can be arbitrarily changed by changing the length of the relay rod piece 6. It is adjustable.

Next, on the upper surface of the support plate 3, there is a table plate 1 attached to the lower part via a hinge 2 having a ratchet and a lock mechanism for angle adjustment and folded to the support plate 3 side. . Then, after the support plate 3 is fixed to the handle 15, the table plate 1 is opened toward the front while using the ratchet mechanism, and when it is in the horizontal state, it is locked by the hinge 2 with the lock mechanism, so that it can be used as a table. .

Further, as shown in FIG. 6, the table plate 1 may have a hollow structure and the auxiliary table 10 may be provided inside. In this case, after the table board 1 is installed, the auxiliary table 10 can be pulled out to the left and right of the table board 1 to increase the area used for the table board 1.
Further, when using a notebook type personal computer or the like, it is also possible to place auxiliary equipment such as a mobile phone or a communication cable, and materials.

Next, consider a case where the handle fixing portion 4 is attached to the handle 15 not in the horizontal direction but in the vertical direction.

First, when the handle fixing portion 4 is attached to the left and right of the handle 15, it is preferable that the opening angle of the handle fixing portion 4 is always equal to the left and right, including the symmetrical state. Because the handle support plate 3 is the user (driver)
Since the support plate 3 does not face the handle upper surface accurately and evenly in parallel with the ground,
This is because when the table board 1 is opened, it tilts to the left or right or falls off.

Then, the handle fixing portion 4 is attached to the handle 15
On the other hand, when it is installed vertically, the upper surface of the handle 15 and the surface of the fixed support plate 3 do not necessarily have to be parallel. This is because a slight difference in angle is the inclination angle of the support plate 3 and is not reflected in the left and right angles of the table plate 1 (however, in both cases, when the table plate 1 is attached horizontally to the ground at the time of installation). Also needed,
It is also necessary to maintain a distance from the operation transmission unit 9 at the center of the handle). In this case, there is no problem even if only one of the spring-shaped springs 14 gives a turning moment to the handle support bar piece 5.

Next, of the two handle fixing portions 4 provided on the support plate 3, only one of the handle fixing portions 4 has the spring-shaped spring 14
When a semi-fixed type that does not use the spring-like spring 14 and is fixed after rotating to a certain degree is used as a semi-fixed type, the handle support bar piece of the first folded handle fixing section 4 is applied. One of 5 (attached to the upper part of the handle peripheral edge 8 at the time of installation) is the handle 1
Any angle with respect to 5 (eg perpendicular to the support plate 3)
The mechanism (semi-fixed type) is automatically fixed at that position when it is raised to the position. Then, the first raised and fixed handle supporting portion bar piece 5 is put on the handle peripheral portion 8 from the upper portion of the handle 15, and after the left and right are balanced, a rotation by the spring-like spring 14 on the lower side of the handle 15 is performed. The second handle support rod piece 5 having a dynamic moment is pulled out and opened, and is clamped and fixed from the outside of the lower portion of the handle 15 toward the inside by utilizing the rotational moment (force) of the spring-shaped spring 14.

In this case, since only one spring-shaped spring 14 is provided, it is expected that the cost can be reduced, and at the same time, the attachment and detachment of the support 3 to and from the handle 15 can be relatively easy. In addition, when the support body 3 is attached in the left-right direction of the handle 15 and when it is attached in the up-down direction, the number of places supporting the handle 15 is four.
It is a point and it is expected that the supporting force will not change.

Next, a case where the support body 3 is supported by the handle 15 at three points will be described.

When fixing something to an annular object such as the handle 15, for example, as in the present embodiment, four points (two curved portions of the handle support bar piece 5 are provided, a total of four on the left and right sides).
When the handle 15 is fixed at a certain position), the handle 15 is gradually pressed from the left-right direction (or the up-down direction) so as to cut out a part of the circumference created by the handle 15. It is expected that it will be too close to the center of the handle and become too deep, and that it will be difficult to remove depending on the mounting angle of the handle support bar piece 5.

Therefore, for example, when the handle fixing portion 4 is attached to the handle 15 in the vertical direction, the lower second handle supporting rod piece 5 is made long (fixed at two places as usual), but the upper portion is fixed. In the case of the handle support rod piece 5 of No. 1, the width is extremely short (for example, a hook shape is also possible) and the fixing portion is made into a single point. Is expected to be easier.

In this case, the spring-shaped spring 14 which gives the turning moment may be provided only on the upper part.
This is considered to be an excellent method for stability,
Even if the user inadvertently applies a load to either the left or right side of the table plate 1, the second handle support bar piece 5 at the lower portion must be securely fixed and have a sufficient length. If so, it seems that there is no problem of easy removal from the handle 15.

As described above, according to the present embodiment, at least two portions are provided on the support, and a part of the outer peripheral portion of the handle is securely sandwiched from the outer side to the inner side of the handle. Since the lower surface and the outer end surface of the operation transmitting portion at the center of the handle are provided with a handle fixing portion that is fixed so that a space is provided between the lower surface and the handle, even if external force is applied to the support, it is difficult for the support to fall off from the handle. The support can be reliably fixed to the handle regardless of the structure of the operation transmission part in the center of the handle, and further, since the support does not contact the operation transmission part in the center of the handle, damage or malfunction due to contact is unlikely to occur.

Further, the table plate 1 can be easily attached to the handle 15 in a stopped automobile, and office work, meals, reading and the like can be easily performed.

Further, the support 3 can be relatively easily attached to or detached from the handle 15 regardless of the diameter, thickness, installation angle, etc. of the handle peripheral portion 8, and the table plate 1 can be set at any angle. It is possible to adjust the angle of. Further, it is possible to freely adjust the angle of the table plate after attachment.

Further, since the support plate 3 is fixed at a certain distance from the horizontal plane created by the handle 15, malfunction due to contact with a horn or an air bag installed in the operation transmission section 9 at the center of the handle, It is possible to prevent damage.

Further, since the table plate 1 and the support plate 3 are firmly fixed on the handle 15, the table plate 1 and the support plate 3 have such a structure that they are not easily detached by an external force from any of the up, down, left and right directions.

The workbench 16 is easy to fold and has a single plate shape when folded, so that it can be easily carried and stored.

[0065]

According to the present invention, at least two portions are provided on the support, and a part of the outer peripheral portion of the handle is securely sandwiched from the outer side to the inner side of the handle, and further, the lower surface of the support and the handle. In order to provide a fixing portion that is fixed so as to provide a space between the central operation transmitting portion outer end surface,
Even if external force is applied to the support, it does not easily come off from the handle, and this fixing part allows the support to be securely fixed to the handle regardless of the structure of the operation transmission part in the center of the handle. Does not come into contact, so damage or malfunction due to contact is unlikely to occur.
