この考案は、農用トラクタ等の車両に立設される安全フ
レームの構造に関する。[Detailed Description of the Invention] This invention relates to the structure of a safety frame installed upright on a vehicle such as an agricultural tractor.
周知のように農用トラクタ等の車両には、門型などの安
全フレームを立設し、該フレームによって車両転倒時の
危険からオペレータを防護するようにしである。As is well known, vehicles such as agricultural tractors are provided with a safety frame such as a gate type, and the frame protects the operator from danger when the vehicle falls over.
この場合安全フレームの下半部は、機体に合わせて細巾
状とされ、−力士半部は、オペレータを広い安全域とし
て護るべく可及的に巾広なフレーム構造とするのが通例
であり、これに従ってフレームの上下間には、曲部が形
成されるものである。In this case, the lower half of the safety frame is made narrow to match the fuselage, and the wrestler half usually has a frame structure as wide as possible to protect the operator with a wide safety margin. Accordingly, a curved portion is formed between the top and bottom of the frame.
しかし乍ら従来のフレームでは、例えば四角筒でなる一
様な断面のものを曲威し、そのままの状態で組立てられ
ていたため、どうしても曲部に応力が集中し、殊に曲成
時には曲部の肉厚が薄くなるのが加工上において通例で
あることもあって該曲部を発端としてフレームが折損す
る確率は極めて大きく、この解決策が望まれている処で
ある。However, in conventional frames, for example, square tubes with a uniform cross section were bent and assembled in that state, stress was inevitably concentrated on the curved parts, especially during bending. Since it is common for the wall thickness to become thinner during processing, there is an extremely high probability that the frame will break at the curved portion, and this solution is desired.
この考案は上記に対処すべく工夫されたもので。This idea was devised to deal with the above problem.
その目的とする処は、縦フレームを筒状に形成すると共
にその中途部の内部を利用して補強部材を設けて中途部

折曲されて曲部が形成されており、その中途部の内部に
は２箇所の曲部間より長い補強部材が固着されている点
にある。The purpose of this is to form a vertical frame into a cylindrical shape and use the inside of the midway part to provide a reinforcing member to reinforce the curved part of the midway part. It provides a safety frame structure for vehicles, and its feature is that the safety frame is formed by connecting the upper ends of a pair of left and right vertical frames installed upright on the vehicle with a connecting frame. , the vertical frame is formed into a cylindrical shape by joining two members, and the middle part thereof is bent in the front-rear direction at two places to form a curved part so that the upper part is located rearward than the lower part, The point is that a reinforcing member that is longer than the space between the two curved portions is fixed inside the middle portion.
以下、図示する具体例について説明する。The specific examples shown in the drawings will be described below.
第１図から第３図は、農用トラクタについての第１具体

に従って後輪９が駆動される。1 to 3 show a first concrete plan for an agricultural tractor, in which a hydraulic device 4 with a seat 3 is mounted on the upper part of the rear side of a mission case 2 constructed in the body 1 of the tractor. There is a pair of left and right lift arms 5 that can be raised and lowered freely, and a rear axle case 7 is provided to protrude outward from the brake actuation housing 6 provided on both sides of the case 20, and protrudes through the axle case 7 and the like. rear axle 8
The rear wheels 9 are driven accordingly.
１０は、ミッションケース２の後端底部に横設された取

ームＦが立設されている。Reference numeral 10 denotes a mounting base installed horizontally at the bottom of the rear end of the mission case 2, and a safety frame F is erected through protruding portions on both sides of the base 100.
この安全フレームＦは、左右一対の縦フレーム１Ｌ１１
と、両縦フレーム１１，１１の上端間に渡架した上部連
結フレーム１２．並びに上端個所から前向きに張出した
前フレーム１３とを備えている。This safety frame F consists of a pair of left and right vertical frames 1L11
and an upper connecting frame 12, which spans between the upper ends of both vertical frames 11,11. It also includes a front frame 13 extending forward from the upper end.
前記縦フレーム１１は、コ型断面の第１部材１１ａと第
２部材１１ｂとの一対を前後をなすべく対向して一体化

側個所に第２曲部ａ２を形成してフレーム１１の上半部
を側方矢視で垂直にかつ後方矢視で上向き開拡状に形成
している。The vertical frame 11 is formed into a rectangular tube with a uniform cross section by integrating a pair of a first member 11a and a second member 11b with a U-shaped cross section facing each other so as to form a front and a back. The first music section a1 is placed at the frame location corresponding to
A second curved part a2 is formed slightly above the first curved part a1 so that the upper half of the frame 11 is vertical in the side arrow view and upward in the rear arrow view. It is formed in an expanding shape.
即ち、２部材を接合して筒状に形成したフレーム１１を
中途部の２箇所で前後方向に折曲して、上部を下部より
も後方に配置し、居住性を良好にすると共に安全域を前
後方向に長く形成している。That is, the frame 11, which is formed by joining two members into a cylindrical shape, is bent in the front-rear direction at two places in the middle, and the upper part is placed further back than the lower part, thereby improving the comfort of living and increasing the safety margin. It is long in the front and back direction.
これと共に前記第１．第２曲部ａ１゜ａ２をも含む斜杆
部１１ｃ内に帯状の長い第１補強部材１４を縦断状に固

材１５の複数個を列状に固着しである。Along with this, the first. A long strip-shaped first reinforcing member 14 is fixed longitudinally in the diagonal rod portion 11c including the second curved portions a1 and a2, and in addition to this first reinforcing member 14, a plurality of short strip-shaped second reinforcing members 15 are attached. The pieces are fixed in a row.
より具体的には、前側の第１部材１１ａ内に概ね沿って
第１補強部材１４を予め溶接しておき。More specifically, the first reinforcing member 14 is welded in advance generally along the inside of the first member 11a on the front side.
一方策２部材１１ｂ内には第２補強部材１５を横断状に
溶接しておいてこれら第１．第２部材１１ａ。On the other hand, a second reinforcing member 15 is welded in a transverse manner inside the second member 11b. Second member 11a.
１１ｂが一体化される時点で第１．第２補強部材１４．
１５が内部で互いに接当状態に組合わされるようにしで
ある。11b is integrated, the first. Second reinforcing member 14.
15 are internally assembled in abutment with each other.

９が渡架され、これら中間支持とも相俟って縦フレーム
１１の肉厚は可及的に薄＜シてあって軽量化されている
。Further, in the middle of the vertical frame 11, there is a lower connecting frame 1 connected to a receiver 18 mounted on the housing of the hydraulic device 4.
Along with these intermediate supports, the wall thickness of the vertical frame 11 is made as thin as possible to reduce its weight.
以上詳述した本考案によれば、縦フレームはその中途部

得ると共に。According to the present invention described in detail above, even if the vertical frame is bent at two places in the middle, the vertical frame is formed into a cylindrical shape by joining two members, and the vertical frame has two bends inside the middle part. Since the reinforcing member is fixed longer than the space between the parts, it will not break even if there is stress concentration at the curved part, and the safety of the operator can be ensured.
縦フレームの上部が下部より後方に位置しているので、
居住性が良好となると共に安全域を前後方向に長く形成
でき、且つ強固で且つシンプルな構造にすることができ
る。Since the top of the vertical frame is located further back than the bottom,
Comfort is improved, the safety zone can be made longer in the front-rear direction, and the structure can be made strong and simple.
尚、フレームは四角筒に限らず円筒とすることもある。Note that the frame is not limited to a square tube, but may also be a cylinder.
