【発明の属する技術分野】
本発明は、庭木バリカンに関し、詳しくは、上下刃の摺接抵抗を低減して軽快な切断作業を長期にわたっておこなえるようにしようとする技術に係るものである。
【0002】
【従来の技術】
従来、下押し板と上押し板とを結合部においてリベット等にて結合し、下押し板と上押し板との間に上刃と下刃の一方もしくは両方を長さ方向に往復動自在に保持した庭木バリカンにおいては、例えば、上刃に下刃側に突出する突出部を形成することで、上下刃の摺接抵抗を低減している。
【0003】
【発明が解決しようとする課題】
ところが、上刃に下刃側に突出する突出部を形成する場合に、上刃の加工が困難であり、特に、上下刃が突出部において摺接することから、騒音が高く、突出部の摩耗が激しく、製品寿命が短いという問題があった。
【0004】
本発明はこのような問題に鑑みてなされたものであり、下押し板と上押し板とを結合して上刃と下刃の一方もしくは両方を長さ方向に往復駆動自在に保持する構成において、下押し板を有効に利用することで、上下刃の摺接抵抗を低減して軽快な切断作業を長期にわたっておこなえる庭木バリカンを提供することを課題とするものである。
【0005】
【課題を解決するための手段】

【0006】
このような構成によれば、下押し板1の両側部に設けた突出部6、6によって上刃4を押し上げて下刃5に対する摺接抵抗を低減することから、摺接の騒音を低減でき、製品寿命を延ばすことができ、軽快な切断作業を長期にわたっておこなえ、しかも、従来のように上刃に突部を形成して摺接抵抗を低減する構成に比べて上刃4の構成を簡素化して上刃4のコストを抑え、しかして、商品価値を大幅に高めることができる。
【0007】
この場合、回転する出力軸19に偏心カム20を設け、偏心カム20の上部カム部20aを上刃4の連係孔4aに連係し、偏心カム20の下部カム部20bを下刃5の連係孔5aに連係する上下刃4、5の駆動構成においては、下押し板1の両側部に設けた突出部6、6によって上刃4を押し上げることから、上刃4と下部カム部20bとの摺接を防止することができ、下刃5と上部カム部20aとの摺接を防止することができ、偏心カム20における騒音の発生を防止することができ、一層、騒音を低減できるものである。

【0011】
請求項5においては、突出部6は、下押し板1と上押し板2との間に保持されて上刃4より柔らかい部材25であることを特徴とするものである。このような構成によれば、柔らかい部材25によって騒音を抑えることができ、かつ、上刃4の摩耗を防止することができる。
【0012】
請求項6においては、上刃4より柔らかい部材25は、本体ハウジング11に一体化していることを特徴とするものである。このような構成によれば、上刃4より柔らかい部材25の突出部6は本体ハウジング11に一体化されて部品点数を低減し、組み立て性を向上することができる。
【0013】
請求項7においては、突出部6は、下押し板1を断面略逆U字状に折り曲げて頂部に凸曲部27を形成していることを特徴とするものである。このような構成によれば、上刃4と突出部6との摺接抵抗を低減でき、一層、騒音を抑えることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a garden-wood hair clipper, and more particularly to a technique for reducing the sliding contact resistance of upper and lower blades so that a light cutting operation can be performed over a long period of time.
[0002]
[Prior art]
Conventionally, the lower pusher plate and the upper pusher plate are coupled with a rivet or the like at the coupling portion, and one or both of the upper blade and the lower blade are held between the lower pusher plate and the upper pusher plate so as to reciprocate in the length direction. In the garden-wood hair clipper, for example, the sliding resistance of the upper and lower blades is reduced by forming a protruding portion that protrudes toward the lower blade on the upper blade.
[0003]
[Problems to be solved by the invention]
However, when the upper blade is formed with a protruding portion that protrudes toward the lower blade, it is difficult to process the upper blade. Particularly, since the upper and lower blades are in sliding contact with the protruding portion, the noise is high and the protrusion is worn. There was a problem of intense product life.
[0004]
The present invention has been made in view of such a problem, in a configuration in which the lower pressing plate and the upper pressing plate are combined to hold one or both of the upper blade and the lower blade so as to be reciprocally driven in the length direction. An object of the present invention is to provide a garden-wood hair clipper capable of reducing the sliding contact resistance of the upper and lower blades and performing a light cutting operation over a long period of time by effectively using the lower push plate.
[0005]
[Means for Solving the Problems]
In claim 1, the lower push plate 1 and the upper push plate 2 are joined at the joint portion 3, and one or both of the upper blade 4 and the lower blade 5 are placed in the length direction between the lower push plate 1 and the upper push plate 2. A garden-wood hair clipper that can be reciprocally driven at both ends, and is provided with protrusions 6 that push up the upper blade 4 on both sides of the lower pressing plate 1 to reduce the sliding contact resistance of the upper and lower blades 4, 5. Is.
[0006]
According to such a configuration, since the upper blade 4 is pushed up by the protrusions 6 and 6 provided on both sides of the lower pressing plate 1 and the sliding resistance against the lower blade 5 is reduced, the sliding noise can be reduced, Product life can be extended, light cutting work can be performed for a long time, and the structure of the upper blade 4 is simplified compared to the conventional structure in which a protrusion is formed on the upper blade to reduce sliding resistance. Thus, the cost of the upper blade 4 can be reduced, and the commercial value can be greatly increased.
[0007]
In this case, an eccentric cam 20 is provided on the rotating output shaft 19, the upper cam portion 20 a of the eccentric cam 20 is linked to the linkage hole 4 a of the upper blade 4, and the lower cam portion 20 b of the eccentric cam 20 is linked to the linkage hole of the lower blade 5. In the drive configuration of the upper and lower blades 4 and 5 linked to 5a, the upper blade 4 is pushed up by the projections 6 and 6 provided on both sides of the lower push plate 1, so that the upper blade 4 and the lower cam portion 20b are in sliding contact. The sliding contact between the lower blade 5 and the upper cam portion 20a can be prevented, the generation of noise in the eccentric cam 20 can be prevented, and the noise can be further reduced.
[0008]
According to a second aspect of the present invention, the projecting portion 6 is formed in an arc shape in which the lower push plate 1 is bent and the central portion becomes higher. According to such a configuration, the sliding contact resistance between the upper blade 4 and the protruding portion 6 can be reduced, and noise can be further suppressed.
[0009]
In the third aspect of the present invention, the projecting portion 6 is provided with a plurality of arc portions 23. According to such a configuration, the sliding resistance between the upper blade 4 and the protruding portion 6 can be further reduced, and noise can be further suppressed.
[0010]
According to a fourth aspect of the present invention, the protrusion 6 is a rotating body 24 that is rotatably held between the lower pressing plate 1 and the upper pressing plate 2. According to such a configuration, the sliding resistance between the upper blade 4 and the protruding portion 6 can be further reduced, and noise can be further suppressed.
[0011]
According to a fifth aspect of the present invention, the protruding portion 6 is a member 25 that is held between the lower pressing plate 1 and the upper pressing plate 2 and is softer than the upper blade 4. According to such a configuration, noise can be suppressed by the soft member 25 and wear of the upper blade 4 can be prevented.
[0012]
In the sixth aspect of the present invention, the member 25 softer than the upper blade 4 is integrated with the main body housing 11. According to such a configuration, the protruding portion 6 of the member 25 that is softer than the upper blade 4 is integrated with the main body housing 11 to reduce the number of parts and improve the assemblability.
[0013]
According to a seventh aspect of the present invention, the protruding portion 6 is characterized in that the lower push plate 1 is bent into a substantially inverted U shape in cross section to form a convex curved portion 27 at the top. According to such a configuration, the sliding contact resistance between the upper blade 4 and the protruding portion 6 can be reduced, and noise can be further suppressed.
[0014]
According to an eighth aspect of the present invention, the projecting portion 6 is characterized in that the lower pressing plate 1 is formed in a hemispherical body 28 by bending it into a semispherical cross section. According to such a configuration, the sliding contact resistance between the upper blade 4 and the protruding portion 6 can be reduced, and noise can be further suppressed.
[0015]
According to a ninth aspect of the present invention, the protruding portion 6 is characterized in that a U-shaped portion 29 is formed by bending both side portions of the lower pressing plate 1 into a U-shaped cross section. According to such a configuration, the upper blade 4 can be stably pushed up in the U-shaped portion 29 and stably reciprocated.
[0016]
According to the tenth aspect of the present invention, the protruding member 30 having the protruding portions 6 and 6 formed on both side portions is attached to the lower push plate 1. According to such a structure, the protrusions 6 and 6 are formed on both sides of the protrusion member 30, and the strength of the protrusions 6 and 6 can be stabilized and can be stably reciprocated. it can.
