Description

The present invention relates to a small hand-held horticultural hair clipper device that is compact and lightweight, has a good weight balance in one-hand grip, can be held by both hands, and has excellent operability in accordance with the direction of pruning and mowing.

  Conventionally, there are various types of small hand-held horticultural hair clipper devices including a clipper type cutting blade portion and a motor for driving the cutting blade portion, such as a trimming machine, a hedge trimmer, and a brush cutting device.

  For example, the trimming machine shown in FIGS. 1 and 2 of Patent Document 1 has a clipper-type cutting blade projecting forward from the front end of the main body case 1, and the motor 8 is in a vertical orientation in the front of the main body case 1. The main body case 1 is provided with a gate-shaped handle 7 at the front portion, the rear portion of the main body case 1 is constituted by a gripping portion (hand-held portion), the grip 7 is held by one hand, and the gripping portion is held by the other hand This is a two-handed model that can be held with one hand and trimmed.

  The hedge trimmer shown in FIG. 1 and FIG. 4 of Patent Document 2 has a drive source 10a and a reducer R / G mounted between the rear end portion of the cutting blade portion and the front end portion of the grip (handle) 11. This is a two-handed model with a long grip 11. The drive source 10a is arranged in a vertical orientation.

  The hedge trimmer shown in FIGS. 1 and 2 of Patent Document 3 has a cutting blade projecting forward from the front end of the main body 1, a motor 2 mounted in a vertical orientation in the front of the main body 1, and a rear portion of the main body 2 being It is a one-handed type model composed of a gripping part.

JP-A-60-176519 (FIGS. 1 and 2) JP 2004-357580 A (FIGS. 1 and 4) JP 2001- 211748 A (FIGS. 1 and 2) Japanese Utility Model Publication No. 4-117553 (FIG. 1)

  However, since both the trimming machine of Patent Document 1 and the hedge trimmer of Patent Document 2 have the motor mounted in a vertical orientation, there is a large step between the cutting blade portion and the gripping portion. Various problems are caused in the cutting operation.

  That is, as illustrated in (a) to (f) of FIG. 12 attached to the present application, there are various orientations on the cutting surfaces of hedges, branches and leaves. Further, the trimming surface may be a curved surface in addition to the flat surface. For this reason, it is necessary to make the cutting blade part into a posture that matches the direction of the cutting surface. When the operation of simply cutting one or several branches and leaves is repeated, an operation of frequently changing the direction of the cutting blade portion is further required.

  The steps described above are used to convey the weight of the motor and the cutting blade to the hand holding the grip when the posture of the cutting blade is in the direction shown in FIGS. 12C, 12E, and 12F, for example. The weight burden on the hand is large, the operability (handling) of the direction of the cutting blade is not good, and a large burden is imposed on the maintenance of this orientation.

  In the hedge trimmer of Patent Document 3, the motor 2 is mounted in a vertical orientation, but the gripping part (hand-held part) has a shape that warps downward as it goes to the rear end, so the above-described problem due to the step difference. Has been improved to some extent. However, when the orientation of the cutting blade is, for example, the orientation shown in FIGS. 12C and 12F attached to the present application, the orientation of the gripping portion (the orientation of the hand holding the gripping portion) and the orientation of the cutting blade portion There is a problem that comfortable handling cannot be performed because is not parallel.

  In the hedge trimmer of Patent Document 4, the motor 4 is mounted in a horizontal posture (parallel to the cutting blade portion), but there is a large step between the cutting blade portion and the gripping portion. There are similar problems.

  Since Patent Documents 1 and 2 are both-hand-held models, the operability (handling) in the cutting (pruning) work near the hand is not good. Also, the model with both hands has a major problem in work safety such as falling because an operator cannot hold a stepladder or ladder with one hand when a worker steps on a stepladder or ladder.

  More importantly, since all of the prior art models 1 to 4 are equipped with a heavy motor in front of the gripping part, the weight burden of the motor and the cutting blade part is put on the operator. Give to hand. In the case of the one-handed model of Patent Documents 3 and 4, this weight burden applied to the worker's hand is large, which greatly affects workability and work labor.

The present invention solves the problem of providing a small hand-held horticultural hair clipper device that is compact and lightweight, has a good weight balance in one-hand grip, can be held by both hands, and has excellent operability according to the direction of pruning and mowing. And

The small hand-held horticultural hair clipper device according to claim 1 of the present invention has the following configuration.
(1) A fixed blade having a comb blade shape on one side along the longitudinal direction, a plurality of movable blades that drive in a repulsive direction with respect to the fixed blade, or a comb blade-shaped movable that is driven horizontally in the front-rear direction A clipper-type cutting blade portion having a single blade structure with a blade projects long forward from the front end portion of the housing, and a motor is mounted in the housing. It is converted into a horizontal rotational motion that is decelerated by a gear set provided in the section, and further, this horizontal rotational motion is converted into a forward / backward movement by the crank arm, and the movable blade of the cutting blade portion is moved in the repelling direction through this forward / backward movement. It has a power transmission structure to be driven.
(2) The housing has a single short hollow shape provided with a bulging portion constituting the front portion and a handle portion corresponding to a portion extending from the middle portion of the length following the bulging portion to the rear end portion. It has a thick bar shape.
(3) The handle portion is configured with a one-hand grip portion at a position near the front portion, a motor serving as a driving source for the cutting blade portion is disposed in a thick tube portion behind the one-hand grip portion, and the thick tube portion A rear portion that can be held by one hand and can be held by both hands together with the one-hand holding portion is provided.
(4) A power switch of the motor is provided in the handle portion, and the gear set is provided in the bulge portion.
(5) The motor is arranged in a lateral orientation along the length direction of the housing at a location behind the middle portion of the length in the housing.
(6) The center of gravity of the entire apparatus including the cutting blade portion is positioned in the middle portion of the length, and the middle portion of the length is configured as an optimum one-hand gripping portion.

  The horticultural hair clipper device according to the present invention is devised so that it can be easily grasped (hand-held) with one hand and operated such as pruning work of branches and leaves.

  One of the contrivances is that the horticultural clippers according to the present invention have been reduced in weight. This weight reduction is performed for both the cutting blade portion and the housing. The weight reduction of the cutting blade portion is realized by using a clipper type cutting blade portion having a single-edged structure in which the cutting edge of the cutting blade portion is directed to one side (preferably the left side) along the front-rear direction. The weight reduction of the housing is realized by forming a single short hollow substantially thick bar shape having a handle.

  The cutting blade portion is either a type in which the movable blade is driven in a repulsive direction relative to the fixed blade, or a single comb-shaped type in which the movable blade is horizontally driven in the front-rear direction with respect to the fixed blade. It is used. The former type of cutting blade portion can be said to be the most preferable type because the movable blade is composed of a plurality of arrow-bottom-shaped blades to further reduce the weight. The case where the latter type of cutting blade is used is also included in the scope of the present invention. This type cutting blade portion is also lighter than the conventional movable blade having a double-edged structure in that the movable blade has a single-edged structure.

  Another one of the devices described above is that the horticultural hair clipper device according to the present invention has a shape and structure that is easy to hold with one hand and easy to operate during pruning and cutting. The ease of gripping with one hand can be understood from the fact that the housing has a single short hollow substantially thick bar shape having a handle that can be gripped with one hand.

  The reason why the above operability is good is that a clipper-type cutting blade portion is projected from the front end portion of the housing to the front to suppress the step as much as possible. That is, since the housing is in the shape of a light single short hollow substantially thick bar, the front end portion is not so large that the cutting blade portion can be attached with a large step. When the level difference is suppressed, a good left-right weight balance is maintained even in gripping with the blade edge in one of up and down directions and gripping with the blade edge in an oblique direction.

In the small hand-held horticultural hair clipper device according to the present invention, any length portion of the handle can be grasped with one hand. However, from the viewpoint of ease of operation during pruning and mowing, the center of gravity of the entire device is positioned here so that the middle part of the length, which is the front part of the handle, is an optimal one-hand gripping part. I am letting. This optimal one-hand holding part (the middle part of the length) becomes a part to be held with one hand when pruning and mowing are performed because of easy gripping and operability.

  The position of the motor, which is a heavy object, greatly affects the positioning of the center of gravity. In the present invention, while considering the weight balance with the cutting blade portion or the like, the motor is disposed behind the optimal one-hand grip portion (the middle portion of the length), and the center of gravity is set to the optimal center. It is positioned within the range of the one-hand holding part (the middle part of the length). In the case where a reduction gear is provided alongside the motor, the motor includes the reduction gear and the reduction gear case.

  The short hollow substantially thick bar shape in the handle portion includes a shape including a portion having a slight difference in thickness and cross-sectional shape. It is preferable that the optimum shape of the one-hand holding part (the middle part of the length) is a thickness and a cross-sectional shape that are most easily held (for example, an elliptical shape that is easy to hold while stabilizing the orientation of the apparatus). When the front part following the optimal one-hand grip part (the middle part of the length) is the bulging part, the gripped hand is prevented from slipping from the front.

  The optimum front-rear length of the one-hand grip portion (the middle portion of the length) is optimal in terms of ease of gripping, and the front-rear length in which the gripping hand fits is optimal. It is not intended to limit. For example, the front and rear lengths may be about two fists.

  The rear handle portion following the optimum one-hand holding portion (the middle portion of the length) is assumed to be a thick cylindrical portion having a thickness and a cross-sectional shape capable of mounting the motor inside. The motor used is a commercially available small motor that outputs high torque rotation. For this reason, the said thick cylinder part which mounts this motor inside has the circular cross-sectional shape which swelled slightly larger diameter than the said optimal one-hand holding part (the said middle part of length) which has an elliptical cross-sectional shape, and is optimal. Is done. This bulge prevents the slipping of the hand gripping the optimal one-hand grip (the middle part of the length) from behind.

The power source for driving the small handheld horticultural clippers according to the present invention is a household AC power source or a DC power source using a secondary battery. In a gardening hair clipper device of the type that uses a household AC power source, one end of a power cord is connected to the housing. In the horticultural hair clipper device of the type using the DC power source, the connection portion of the secondary battery is provided in the housing.

  The center of gravity of the gardening hair clipper device that uses a household AC power source may include a part of the weight of the power cord. In the horticultural clipper apparatus of the type using a secondary battery as a power source, the center of gravity includes the weight of the secondary battery. In any type of horticultural hair clipper device, the center of gravity is within the range of the optimum one-hand holding portion (the middle portion of the length).

According to a second aspect of the present invention, there is provided a small hand-held gardening hair clipper device according to the first aspect, wherein the cutting blade portion is driven horizontally in the reed action direction with respect to the fixed blade and the fixed blade. A plurality of movable blades, and an advancing / retracting member made of a long thin plate for driving the movable blade, and one or more of the fixed blade, the advancing / retreating member, and the movable blade are lightweight. One or a plurality of openings are provided to facilitate the process.

A small handheld horticultural hair clipper device according to claim 3 is the same as that of claim 1, and further, the cutting blade part is a fixed blade and a comb blade-like movable blade that is horizontally driven in the front-rear direction. One or a plurality of openings for reducing the weight is provided in either or both of the fixed blade and the movable blade.

A small hand-held gardening hair clipper device according to claim 1 has a cutting blade portion having a plurality of movable blades that are horizontally driven in a repelling direction with respect to a fixed blade, and a comb blade-like shape that is horizontally driven in the front-rear direction. One of the cutting blade parts provided with the movable blade is equipped. In Claims 2 and 3, an opening is provided in one or a plurality of members constituting the cutting blade portion to further reduce the weight.

According to the small hand-held horticultural hair clipper device according to claim 1, as a result of positioning the center of gravity in the optimum one-hand gripping portion, the weight balance when the device is gripped with one hand is improved, and the weight burden of the hand Is reduced and operability is improved. In particular, as a result of making the whole housing into a single short hollow substantially thick pattern, the posture of the apparatus can be changed easily and instantaneously only by changing the orientation of the gripping handle.

According to the small handheld horticultural hair clipper device according to claims 2 and 3, the weight of the cutting blade portion is obtained as a result of providing an opening for reducing the weight in any one or a plurality of members constituting the cutting blade portion. Is greatly reduced. For this reason, the position of the center of gravity can be set more reliably, and a horticultural hair clipper apparatus that is lighter and has better operability can be obtained.
