DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for an operation grip and a throttle lever which are mounted on a rod (ie, a rod-shaped portion such as a handle or a main pipe) so as to be gripped by an operator in a brush cutter. It is.

[0002]

2. Description of the Related Art FIG.
As shown in (a) and (b). First, the brush cutter 1 shown in FIG. 5A is usually called a "two-handle-type brush cutter" and includes a rotary cutter blade 3 at one end of a main pipe 5 and an engine 4 at the other end. , Main pipe 5
A belt 6 for shoulder strap and a U-shaped (single) handle 7 are provided in the middle (portion near the engine 4). The worker puts the belt 6 on his / her shoulder, and
, And grip the operation grips (hereinafter referred to as grips) 8 and 11 near both ends of the handle 7 to determine and move the position of the cutting blade 3. The cutting blade 3 is driven by the engine 4 via a drive shaft (not shown) passing through the main pipe 5, and controls the rotation speed and the like by a throttle lever 16 provided at one end of the handle 7. On the other hand, the brush cutter 2 of FIG. 5B is usually called a “two-grip cutter”, and includes the cutting blade 3, the engine 4, and the main pipe 5 as in the case of FIG.
It has no special handle. The operator determines the position of the cutting blade 3 by gripping two grips 9 and 21 provided on the front and rear of the main pipe 5. The rotation speed of the engine 4 (and the cutting blade 3) is controlled by a throttle lever 26 provided on the main pipe 5.

The main body 7a and the main pipe 5 of the handle 7 (FIG. 5 (a)) are usually constituted by metal rods (hollow pipes, etc.). Is gripped with a grip 8.11 (FIG. 5 (a)) or 9.21 (FIG. 5 (b)) made of rubber, resin, or the like. Throttle levers 16 (FIG. 5 (a)) and 26 (FIG. 5 (b)) are attached to adjacent grips 11 and 21, respectively. They are arranged near the grips 11 and 21 so that the operator can operate them by moving the fingers while holding the grips 11 and 21.

In the case of a "two-grip type" brush cutter shown in FIG. 5B, a throttle lever and a grip are conventionally mounted as shown in FIG. That is, the grip 21 ′ is fixed on the rod of the main pipe 5 by tightening both ends with the fixing bands 23 ′. As for the throttle lever 26 ′, the throttle lever mounting frame 25 ′ is provided immediately adjacent to the grip 21 ′. It is fixedly attached to the main pipe 5. A throttle wire 28 'connected from the throttle lever 26' to the engine (more precisely, a carburetor, none of which is shown) is attached to the mounting frame 2 as shown in FIG.
5 'and once to the outside, and to the other end through a hole 21h' formed in the grip 21 '. The grip and throttle lever mounting structure similar to that shown in FIG.
No. 0122.

On the other hand, in the case of a "one handle type" brush cutter shown in FIG. 5 (a), grips 8 'and 11' are usually pressed into an end of a handle 7 'as shown in FIG. A throttle lever 15 'is attached to the inside of the grip to adjust the opening in accordance with the use state of the brush cutter and to fix the opening. In the above publication (Japanese Utility Model Laid-Open No. 62-60122), a throttle lever for operating a brush cutter is provided outside an operating grip, and an operator grips the operating grip and the throttle lever simultaneously to operate the brush cutter. An arrangement for operation is disclosed.

[0006]

However, in the case of a "two-grip type" brush cutter shown in FIG. 5B, the conventional operation grip and throttle lever shown in FIG. 6 have the following problems. Exists. That is, a) Since the throttle lever mounting frame and the grip are provided independently of each other,
Each must be firmly fixed on the rod.
Therefore, it is necessary to use a strong fixing means such as a fixing band (reference numeral 23 'in FIG. 6) for each of the two.

[0007] b) Relatively many parts are required in connection with fixing the grip as in the above-mentioned a), so that cost and assembly labor are required. This is because some components are required to firmly fix the mounting frame, and both ends of the grip must be fixed with fixing bands as shown in the figure.

(C) Since the fixed band of the grip is disposed between the grip and the throttle lever, the positions of the two are separated from each other, so that it is not very easy to operate the throttle lever while holding the grip.

D) Since the mounting frame and the grip are not integrally disposed, the throttle wire (or further the conducting wire) connected to the throttle lever is exposed between the two as shown in the figure, which is not preferable in appearance.

E) When mounting the grip and the throttle lever on the rod, it is difficult to determine the relative positional relationship between the grip and the mounting frame in the circumferential direction of the rod (the direction of rotation on the rod). This is because the grip and the mounting frame are mounted independently of each other while being adjacent to each other on the rod, and there is no reference to the angular relationship between the two components in the circumferential direction of the rod.

On the other hand, in the case of a "two-handle-type" brush cutter shown in FIG. 5B, f) the conventional throttle lever and operation grip provided as shown in FIG. In addition, since the throttle lever is located inside the grip, there is a disadvantage that the opening of the throttle lever cannot be adjusted while holding the grip.

G) The throttle lever described in the above publication is located outside the operation grip and at a position where operation is relatively easy. However, the throttle lever is simply press-fitted and fixed from the outside of the operation grip. The configuration lacks the reliability of the mounting. In particular, with a general throttle lever in which the operator does not grip the throttle lever together with the grip, that is, does not grip the throttle lever by hand during work, there remains a problem in the fixing method. There is also a problem that assembly and disassembly are difficult. Further, the throttle lever is a dedicated throttle lever attached to the end of the handle, and cannot be shared with a brush cutter of a type in which a throttle lever is provided in the middle of the shaft (for example, the above-mentioned "two-grip" brush cutter).

(H) Further, there is the same problem as (e).

According to the present invention, there is provided an operation grip for a brush cutter capable of solving the above-mentioned problems, such as easy operation of a throttle while gripping the grip, easy and reliable fixing on a rod, and excellent design. And a throttle lever mounting structure.

[0015]

According to a first aspect of the present invention, there is provided a brush cutter with an operation grip and a throttle lever mounting structure, wherein the grip and the throttle lever mounting frame are located adjacent to each other on a rod of the brush cutter. Wherein the mounting frame has a two-part structure that can be joined by sandwiching a rod, and one end of the operation grip is fastened onto the rod by a part of the mounting frame to be joined.

Such a mounting structure has the following operation. That is, a) a part of the mounting frame of the throttle lever tightens one end of the grip, whereby the mounting frame and the grip are restrained in a positional relationship with each other. Therefore, it is easy to fix both on the rod, The stability of both positions is also high. This is because if only one of the mounting frame and the grip is firmly fixed on the rod, the other is fixed at a fixed position on the rod due to the constraint relationship with the other party.

B) Even when both ends of the grip have to be fixed on the rod as shown in FIG. 6, one end is tightened on the rod by the mounting frame. The need for a fixed band or the like near the mounting frame is eliminated. That is, the required number of parts is reduced by that much, and the cost required for manufacturing and assembling the parts is reduced.

C) As described in b) above, since a fixed band for the grip is not required between the grip and the throttle lever, the grip and the throttle lever can be arranged at positions close to each other. This makes it easier to operate the throttle lever with the hand holding the grip.

D) Since the mounting frame and the grip are integrally arranged, the throttle lever and the grip are integrated, which is preferable in appearance. In addition, the mounting frame and the grip, which are integrally disposed, can effectively cover wires and the like that exit from the throttle lever in the mounting frame and enter the grip, so that the appearance can be further improved. In this case, since the wire or the like is not touched when the hand is extended from the grip to the throttle lever, the operation of the throttle lever can be performed with a preferable feel.

According to the second aspect of the present invention, in particular, the operation grip is fixed near the tip of a two-shaped handle provided on the main frame of the brush cutter, and a throttle lever mounting frame is further mounted near the tip. At the very tip of the handle body, a cylindrical cap with one end closed is covered, and the above-mentioned mounting frame has a two-part structure that can be joined by sandwiching the handle body. A part (for example, flange 15f1 shown in FIG. 2 (b)) tightens one end of the operation grip onto the handle body, and a part of the above-mentioned mounting frame to be joined which is different from the above part (for example, FIG. 2 (b)). The cap is tightened on the handle body by a flange 15f2) shown in FIG.

According to such a mounting structure, the above a) to d)
In addition, e) The throttle lever is located adjacent to the outside (tip side) of the grip, so that the opening of the throttle lever can be easily adjusted while holding the grip.

F) Since the mounting frame of the throttle lever is fastened and fixed on the handle main body by two places (the two "parts" described above), the mounting is reliable.

G) Since the outside of the handle is covered by the cap, the appearance can be improved. Also, the cap is fixed on the handle with the throttle lever mounting frame, so simply inserting it into the handle body,
It can be fixed securely and is easy to install.

H) The mounting frame of the throttle lever is mounted on the outer periphery of the cap and the grip, and the inner diameter of the mounting portion can be freely selected. Therefore, the mounting portion includes the mounting portion including the main pipe having an outer diameter larger than the handle body. Can be common. Therefore, it is possible to use a common throttle lever for the "one handle type" brush cutter and the "two grip type" brush cutter.

According to a third aspect of the present invention, in addition to the above structure, a wiring hole for passing a throttle wire of the throttle lever is formed in the grip, and a surface of the mounting frame is provided on the grip. A hollow projection is formed on the end surface on the side to be inserted, the projection is inserted into the wiring hole, and the throttle wire of the throttle lever is passed from the hollow portion of the projection of the mounting frame into the wiring hole of the grip. Features.

With such a mounting structure, i) the throttle wire connected to the throttle lever in the mounting frame is not exposed outside between the mounting frame and the grip. This is because the throttle wire that reaches the engine (such as a carburetor) of the brush cutter comes out of the hollow portion of the protrusion of the mounting frame and passes through the wiring hole of the grip without being exposed to the outside. If the throttle wire is not exposed between the mounting frame and the grip, the appearance is favorable as described in d) and the operation of the throttle lever can be performed with a good feeling.

J) When the grip and the throttle lever are mounted on the rod, the relative positional relationship between the grip and the mounting frame in the circumferential direction (the direction of rotation on the rod) naturally becomes uniform. This is because the hollow projection provided on the end face of the mounting frame is inserted into the wiring hole of the grip as described above. When the positional relationship is naturally determined in this manner, it becomes easier to assemble the throttle lever and the grip on the rod. Also, the mounting frame and the grip are connected and restrained by tightening one end of the grip with a part of the mounting frame as described above. Top and appearance integrity is further enhanced.

[0028]

1 and 2 show an embodiment of the present invention. FIG. 1 is a front view of a handle 7 of the bush cutter 1 shown in FIG.
2A is a sectional view taken along line aa in FIG. 1, FIG. 2B is a sectional view taken along line bb in FIG. 1A, and FIG. 2C is a sectional view taken along line cc in FIG. .

As described above, the grip 8 and the grip 11 are attached to the vicinity of each end of the handle 7 in the brush cutter 1 shown in FIG. As for the grip 11 on one side (the side that the operator grips with the right hand), a throttle lever 16 is mounted together with the mounting frame 15 on the handle 7 at a position adjacent to the outer end of the grip 11 (on the side of the right thumb), The throttle lever 16 can be operated with the grip 11 held by hand. The mounting frame 15 has a throttle lever 16 of a type in which the opening is freely adjusted according to the usage state of the brush cutter to control the rotation speed of the engine 4 and the position of the opening is fixed and held, and the engine Stop switch 1 to stop 4
7 is also provided.

The grip 11 and the mounting frame 15 are configured as follows so that they are functionally integrated and stably positioned on the handle 7.

1) Like the other grip 8, the grip 11 is entirely made of rubber, and is pressed into the outside of the handle body 7a made of an aluminum pipe, or is fixed with an adhesive or the like. In other words, the grip 11 has its entire inner surface fixed to the outer peripheral surface of the handle body 7a based on its own elastic force or adhesion, and the frictional force between both surfaces can be obtained without using a fixing band or the like. The grip 11
Is designed not to fall out or turn around. When the grip 11 comes into wide contact with the handle body 7a,
The vibration of the handle 7 is transmitted to the worker's hand without being greatly attenuated, but the end of the handle 7 has relatively little vibration, and the brush cutter is supported on the worker's shoulder by the belt 6 during the work. , And the above structure.

2) Mounting frame 15 such as throttle lever 16
Is fixed on the handle 7 with the configuration shown in FIGS. 2 (a) and 2 (b). That is, the mounting frame 15 is as shown in FIG.
As shown in the figure, a split structure consisting of two halves 15a and 15b is used. The two halves are connected by a pin 15c so as to be swingable, and are joined to the handle 5 by a screw 15d on the opposite side of the pin 15c. Shall do. The flange 15 has a box-like shape having a space therein, and has a circular hole 15e which is a fixing portion to the handle 7 on both sides as shown in FIG.
f1 · 15f2 are formed.

3) When the mounting frame 15 is joined as described above, the groove 11a at one end of the grip 11 is tightened by the flange 15f1 as shown in FIG. 2B. With this configuration, the mounting frame 15 does not move away from the grip 11 in the axial direction or moves in the rotation direction, and the integration with the grip 11 is extremely enhanced. The grip 11 is securely mounted on the handle 7 as described in 1) above.
The grip 11 and the mounting frame 15 are both stably mounted on the handle. Although the grip 11 and the mounting frame 15 will be arranged in a very close position,
According to this, the unity of both in the design increases,
Throttle lever 1 by hand holding grip 11
The functional integrity that the user can easily operate 6 is also improved. As shown in FIG. 2 (b), a resin cap 15j having a flange 15j1 at the outer end and a fitting portion 15j2 fitted to the handle body 7a inward is attached to the end of the handle 7 as shown in FIG. The cap 15j is fastened by the flange 15f2 on the outside of the mounting frame 15 by engaging with the end. Therefore, the mounting frame 15
Are securely attached to the handle 7 at both inner and outer ends. Further, since the outer end surface of the mounting frame 15 is covered with the flange 15j1 of the cap 15j, the appearance can be improved. Since the cap 15j is fastened by the mounting frame 15, there is no danger that the cap 15j will come out even if it is loosely fitted to the handle main body 7a, and the assembly is easy. Also, the mounting frame including the throttle lever can be used in common with a type in which a throttle lever is mounted on an intermediate portion of a pipe, such as a "two-grip type" brush cutter. In the above case, the mounting frame 15 is
Although the flanges 15f1 and 15f2 are mounted on the grip 11 and the cap 15j, the flanges 15f1 and 15f are mounted on the handle body 7a.
It is of course also possible to directly tighten both sides or one side of the two.

4) As shown in FIG. 2 (b), a throttle wire 18 leading to a carburetor (not shown) is connected to a throttle lever 16 provided on the mounting frame 15, and a stop switch 17 is connected to an ignition system. Leading wires 19 are connected, but they are not exposed from between the mounting frame 15 and the grip 11. That is, wire 1
8, a hollow projection 15p formed on the mounting frame 15
After passing through the wire body 18a, the outer cylinder 18b of the wire 18 is applied to the stopper 15q provided in the hollow projection 15p, and the main body 18a and the outer cylinder 18b are passed through the grip 11 in the longitudinal direction. It is placed in the hole 11h (see FIG. 2 (c)). In addition, the conducting wire 19 passes through a wiring hole 11h of the grip 11 from a groove (or hole) outside the projection 15p (see also FIG. 2C).
If the wires 18 and the like are not exposed between the mounting frame 15 and the grip 11 in this way, the overall appearance is improved, and the throttle lever 16 and the like are easy to operate, resulting in an excellent function.

5) The protrusion 15p through which the throttle wire 18 passes through the mounting frame 15 is inserted into the end of the wiring hole 11h of the grip 11, as shown in FIGS. 2B and 2C. In this manner, the relative positional relationship between the grip 11 and the mounting frame 15 in the rotation direction is automatically determined, so that the mounting frame 15 is easily assembled, and the grip 11 and the mounting frame 15 rotate relative to each other. It has gone further, and the functional unity of both has increased further.

3 and 4 show another embodiment of the present invention. FIG. 3 is a side view showing the vicinity of the engine 4 and the shoulder belt 6 in the two-grip brush cutter 2 shown in FIG. 5B, and FIG. FIG. 3 is a detailed view of a part (the upper half is shown in cross section).

In the brush cutter 2 shown in FIG. 5B, the grip 9 and the grip 21 are mounted on the main pipe 5 at the front and rear portions of the shoulder belt 6 as described above. As for the operation grip 21 close to the engine 4 (generally, the side gripped by the right hand by the operator), the throttle lever 26 and the throttle lever 26 are positioned adjacent to the grip 21 on the main pipe 5 (toward the right thumb). A stop switch 27 is attached. The throttle lever 26 and the stop switch 27 are arranged on a mounting frame 25, and the mounting frame 25 and the grip 21 are connected to each other as shown in FIG.
And adjacent to each other as shown in FIG. Reference numeral 6a in FIG. 3 is a fastener for the shoulder strap 6.

The grip 21 and the mounting frame 25 are configured as follows so as to exhibit various advantages while exhibiting design and functional integrity.

1) In the case of a two-grip type brush cutter, most of the work is performed while the gripper 9/21 supports the entire brush cutter by hand. Therefore, the grips 9 and 21 are of a vibration-proof type as shown in FIG. That is, the grip 21 is entirely formed of an elastic material such as rubber, elastomer or resin, and a hard resin tube 22 is mounted inside the middle portion 21c to form the main pipe 5.
And a circumferential gap 21x is provided between them. Thus, the grip 21 contacts the main pipe 5 only at both ends 21a and 21b. Therefore, most of the vibration transmitted from the engine 4 through the main pipe 5 is not directly transmitted to the middle portion 21c held by the operator, but is transmitted by being attenuated by the rubber end portions 21a and 21b. Does not feel strong vibration.

2) As described above, the grip 21 comes into contact with the main pipe 5 only at the two end portions 21a and 21b. Therefore, in order to secure the fixed state of the grip 21 on the main pipe 5, the mounting of the grip 21 is performed. A fixed band 23 formed by winding a coil spring in an annular shape is attached to (the groove of) the end 21b farther from the frame 25. The grip 21 is firmly fixed by supplementing the fastening force of the end 21 b of the grip 21 to the main pipe 5 with the fixing band 23.

3) The mounting frame 25 is the mounting frame 1 shown in FIG.
The structure is the same as that of FIG. 5, and a two-part structure that can be joined is used. When the two pieces are joined, a part of them is used to tighten the groove at one end 21a of the grip 21 as shown in FIG. In order to fix the grip 21 as described above, the end 21a opposite to the side where the fixing band 23 is used may be fastened to the main pipe 5 with a fixing band. Since there is a mounting frame 25 provided with the like, when the fixing band is fitted to the end portion 21a, the grip 21 and the mounting frame 25 are separated from each other, and the operability of the throttle lever 26 and the like is reduced. Therefore, by tightening the grip 21 with the mounting frame 15 itself,
The grip 21 is firmly fixed on the main pipe 5, the connection between the grip 21 and the mounting frame 25 is strengthened, and at the same time, the operability of the throttle lever 26 and the like is improved. By doing so, there is an advantage that the required number of the fixing bands 23 is reduced and the appearance (design) is improved. The mounting frame 25 is not different in shape from the mounting frame 15 in FIG. 2 except for the presence or absence of the cap 15j. Reference numeral 25d in FIG. 4 denotes a screw for joining two pieces of the divided structure.

4) As shown in FIG. 3, from the mounting frame 25, a throttle wire 28 connected to a throttle lever 26 mounted in the mounting frame 25 and a stop switch 2
Although the conductor 29 connected to 7 extends toward the engine 4, between the mounting frame 25 and the grip 21, they are not exposed to the outside. The reason why the wires 28 and the like are not exposed to the outside is that the hollow projections 15p
Similarly to the case of forming the hollow, a hollow projection 25p is also formed on the mounting frame 25 in FIG.
This is because the above-mentioned wire 28 was passed through the inside of the wiring hole 21h in 1 and the conducting wire 29 was made to follow it (this configuration is the same as that of FIG. 2). If the wires 28 and the conductive wires 29 are not exposed between the mounting frame 25 and the grip 21, the operability of the throttle lever 16 and the like is improved as well as the appearance.

5) As shown in FIG. 4, the projection 25p provided on the mounting frame 25 is inserted into the end of the wiring hole 21h of the grip 21. Thus, as described above, assembling of the mounting frame 25 of the throttle lever 26 is facilitated, and the functional integrity of the grip 21 and the mounting frame 25 is further improved.

The two embodiments have been described above, but it goes without saying that the invention can be implemented in other forms. It is of course possible to adopt the grip and throttle lever mounting structure of the present invention on a rod other than those described above in a brush cutter of a type other than that shown in FIGS. 5 (a) and 5 (b).

[0045]

The structure for mounting the operation grip and the throttle lever in the brush cutter according to the first aspect has the following effects. That is: a) It is easy to fix the mounting frame and the grip of the throttle lever on the rod, and the stability of both positions is high.

B) Even if both ends of the grip have to be fixed on the rod, one end is fastened on the rod by the mounting frame, so that the number of required parts such as fixing bands is reduced, and Manufacturing and assembly costs are reduced.

C) Since a fixed band is not required between the grip and the throttle lever, the grip and the throttle lever can be arranged close to each other, and the operation of the throttle lever becomes easy.

D) The appearance is preferable because the mounting frame and the grip are integrally disposed.

In the mounting structure according to the second aspect, in addition to the above, e) Since the throttle lever is disposed adjacent to the outer side (tip side) of the grip, the throttle lever can be easily held while holding the grip. The degree of opening can be adjusted.

F) The installation frame of the throttle lever is easy to install because both ends are fastened and fixed to the handle.

G) Since the outside of the handle is covered by the cap, the appearance can be improved. In addition, the cap can be securely fixed, and mounting is easy.

H) Since the inner diameter of the mounting portion of the throttle lever mounting frame can be freely selected, the throttle lever can be shared between the "one handle type" brush cutter and the "two grip type" brush cutter. Become.

According to the mounting structure of the third aspect, i) since the throttle wire is not exposed to the outside between the mounting frame and the grip, the appearance is favorable and the operation of the throttle lever can be performed with a good feeling.

J) Since the hollow projection provided on the mounting frame and the wiring hole of the grip are fitted to each other, the grip and the mounting frame can be easily mounted on the rod, and the function of the mounting frame and the grip can be improved. The appearance integrity is improved.
