Description

" Maas fork in the door " and two oar devices *

The invention belongs to the two oars of a kind of manually driven of with the hands directly the not grasping oar device that paddles automatically.Can be applicable on the single or double canoe, can be applicable to single, double, three rows or four rows etc. side by side on small-sized (10 people), medium-sized (50 people), large-scale (100 people's) of the manual multi-person behaviour oar of seat the various manpowers canoes.

The two oars of traditional available man-power have sitting posture and standing posture, all are with the hands directly to grasp oar to paddle.The canoe that China is among the people to also have the single sculls of standing posture to paddle so far.External more have the cock boat that common sitting posture single sculls paddles and a scull of single sitting posture paddle.Stand the r Zweier line direction forward, and the entry angle of higher pair of oar of the side of a ship is bigger, and oar is long shorter, and the effect of exerting oneself of standing is relatively poor; Cock boat in the two oars of sitting posture, shipping agency direction backwards, higher pair of oar entry of side of a ship angle is big, oar long short, when being seated firmly, because the side of a ship is higher, two oar entry angles are bigger, and often both hands will be higher than chest when entry is firmly paddled, so firmly effect is general; The sitting posture scull, the shipping agency direction backwards, side of a ship adjoined water surface is very near, so two oar entry angles are very little, so oar is very long, its force method can be put forth one's strength by whole body as sit-ups, both hands are best results firmly about chest abdomen height generally, and two oars of above-described standing posture and the two oars of sitting posture respectively have its advantage and weak point.

The purpose of this invention is to provide a kind of by manpower drive with the hands directly do not grasp again oar, shipping agency direction forward, the big oar of higher, the two oar entry of side of a ship angle is long shorter, available standing posture, sitting posture or the multiple posture of sit-ups formula are paddled, can single, double or many people standardized two oar devices or many people draw two oar devices of two or more polyphones altogether altogether.Can be for civilian use, match with, can for group sail across a sea exercise with, also can for lie fallow and the big cockleshell of various manpowers of two oar devices of tourist recreation use on.

Two vertical core line of centerss under same plane on two A-frames that stretch out outside the ship side perpendicular to the X-X axis and will with geometric centre O symmetry, the circular groove center that is fixed on two round tracing point plates on the same plane, inboard will be projected on OO ' axis, two sliding sleeves and two rollers are enclosed within respectively on the arm bar and circle tracing point pillow block on the left and right driving bar, and insert respectively among the vertical core on the A-frame and in the shape annular groove of circle tracing point plate force arm moving point a on the left and right driving bar and circle tracing point m are retrained; The centre of sphere parallel connection of two straight moving tracing point b in movable joint on the left and right driving bar is locked in motion between B, the B ' on the Y-Y axis with the good upper and lower globe bearing of lapping-in and double nut at 2 with the centre of sphere b on the ball-joint.Mobile jib sliding suitable mistake from the ball-joint hole is hinged in fulcrum O ' with firm banking with pivot pin, and intrinsic two guide rails parallel and that be symmetrical in the Y-Y axis retrain centre of sphere b translation on header board and two bearings in the movable joint groove of left and right sides drive spindle parallel connection.The actuating arm that attachment point bar in the former pantagraph mechanism is driven on the bar merges.Left and right loom and left and right rocking bar be encased on the left and right driving bar on separately the gap slot be hinged in corresponding two seat holes, by the biplate connecting rod loom and rocking bar lower end convergent-divergent point S being hinged becomes two oar scaling devices of articulated parallel connection again.The intersection point h of axis of symmetry aj becomes the center of rotation of the two oar convergent-divergents of control on pin axes in the middle of on two rocking bars and the left and right driving bar, and two fixing sectors pivot pin by two ends is pressed into respectively on header board and two bearings accordingly Y ₁Y ₁' and Y ₂Y ₂In ' axis the hole, require on the left and right driving bar two fulcrum h can be respectively during to the X-X axis and sector axis Y in translation ₁Y ₁' and Y ₂Y ₂' overlap.Two cam paths built in XOO ' plane before and after in the curved surface on symmetrical two sector stage casings, in the upper end of two rocking bars pillow block cover upper roller is placed to separately cam path.Both hands are held handle, and the O ' below mobile jib drives fulcrum, serve as to drive the angle with 2 β, and when overlapping centre of sphere b at B point place on the Y-Y axis and begin firmly to B ' drivings, the roller center on its two rocking bar also is in two cam paths and turns back and locate T ₁The starting position, paddle by the two oar entry of the convergent-divergent of the articulated parallel connection of circulation direction of arrow automatic guidance, the roller center to B ' time rocking bar is also to T ₄, two oars are just finished the forced stroke at 2 α paddling angles, are the return of stroke that two oar water outlets are soared from B ' to the reverse drive of B.

The left side of articulated parallel combination, right drive rod, upwards crooked or straight actuating arm is arranged on the front, have on the actuating arm for left, the seat hole that right rocker shaft is installed and groove and the breach and the axis hole that are hinged for loom, the pillow block of doing the movable joint hole of also coupling and matching is prepared in a left side, respectively be integral on the right drive rod, on a left side, right arm board, round tracing point m pillow block on it and the arm bar at force arm moving point a place will separate separately to be made, namely wherein with that drive rod in movable joint hole in order to guarantee guide precision, generally also to use buttcover plate and location securing member (also can be integral).That drive spindle and the arm board with holes of band movable joint pillow block will be pressed on the movable joint pillow block, and by band handle ring, locating dowel pin and fastening fixing screw etc. is hinged together the parallel connection of left and right driving bar again.On overlooking, article two, a, the m on the drive spindle, each particular point of b, h all will be distributed in each corresponding point position on the diad aj, b with the centre of sphere place of two straight moving tracing point b in movable joint on the Y-Y axis intersects in parallel, have only translation instantaneous to geometric centre O on the Y-Y axis as centre of sphere b, the diad aj on two drive spindles just can coincide with straight line.

Two opposing sectors that are fixed between header board and two bearings, conformability must be strict with in the geometric configuration of the cam path on it, size and installation site, can guarantee synchronous, the automatic entry of two oars, the paddling program of water outlet.Be assemblied in one and convergent-divergent point S hinge of two rocking bars in the two driving arm seat holes, middle spaced winding h point rotates, the cover upper roller respectively places left and right fixing cam path on the pillow block of other end, along with the back and forth translational motion between the B on the Y-Y axis, B ' of the centre of sphere b on the left and right driving bar of articulated parallel connection, the roller on two rocking bars is forced to press the T of arrow direction in the osed top cam path ₁, T ₂Section is the blade entry section of paddling, T ₂, T ₃Be that blade paddles in water and keeps section, T ₃, T ₄It is the blade water outlet section of paddling.If centre of sphere b support to B ' then rocking bar upper roller center also support T ₄The entry forced stroke that paddles is finished in the some position.Centre of sphere b then is that blade is in lifting return of stroke on the water surface from B ' to the motion of B point.

One of the movement characteristic of " Maas fork in the door " is on the bar, a, m, three particular points of b are to retrain respectively by outside moving with movement locus certainly, on the bar remaining arbitrfary point all take geometric center O as elliptical center by the orbiting motion of elliptic curve from each, so the movement locus of the center of rotation h on two rocking bars also is elliptic curve, only have when two h points move to the X-X axial location, just respectively with two sectors on central axis Y ₁Y ₁' and Y ₂Y ₂' overlap, when particularly centre of sphere b is in B on the Y-Y axis or B ' position its coincidence error is very not big, but because this worst error is the T at cam path ₁, T ₄Near the point, two blades are that to be in the non-entry idle running state that just begins to prepare entry or water outlet lifting little to impact in the impulse stroke at that time, and available fork upper roller comes inverting processing with the rotation of the cutlery of diameter or revises.

Mobile jib is the input bar of manpower direct drive, and available straight-bar, knee or energy be Telescopic Fixed compound rod arbitrarily.It sleeves in the ball-joint hole, with O ' is the swing fulcrum, make reciprocal output movement with the two paddle mechanisms of the drive spindle convergent-divergent of the articulated parallel connection on the 2 β angle driving guide rail, in each oscillation cycle, its drive torque is to be the alternate of cosine between BO ' and OO ', the actuating speed of its mobile jib be with acceleration/accel gradually after geometric centre O approaches, the alternate of leaving with speed decrescence again.In the mobile jib upper end handgrip axle and the both hands handle that supplies single or double driving usefulness arranged, before the mobile jib upper end, in the rear lug hole or before and after directly in the axis hole of handgrip, being hinged handle stem and and the ship axis below holder line up a plurality of connecting rods and the handle stem hinge that a plurality of holders of a line are hinged, many handgrips of the parallelogram that is driven by many people before and after forming drive input mechanism, if in the handgrip axis hole of mobile jib, fix corresponding cross bar with below line up a plurality of connecting rods on the parallel holder of two of a line or many and a plurality of handle stem and be hinged and form two, article three, or many parallelogram and more handgrip driven two oar devices of two oar devices or two or more front and back polyphone by more people, also can be by driving firmly in the special impulse stroke in one direction of a lot of rowers, allow the rower of small scale in backstroke, drive firmly, two available front and back of oar device handle stem is driven by many people, the available more people of two oar devices of two or more polyphone drives, and can equidistant multi-disc blade be installed at loom.

On the single or double canoe that paddles, or also can be by balance spare and gear in many people racing boat of not using the steersman or on other canoe coaxial fixing together after, be encased on the header board on the fixing jackshaft with two sector front ends on the common engaged transmission of operative gear, the Double-ear-hole of two pedals is fixed in the mast of hull bottom and the spring a row and vertically slides, be hinged at balance spare two and two pedals with two connecting rods, with two pedals, make two sectors respectively around axis Y if jam on the engaged transmission of a certain pedal by gear on two pedals ₁Y ₁' and Y ₂Y ₂' relatively rotate and make two cam paths produce positive and negative change in location and force left and right blade in two oar contracting mechanisms in synchronous entry is paddled, to cause the difference of underwater penetration and produce steering moment ship is changed course to the left or to the right.If with header board, two bearings, two A-frames, two round tracing point plates and two guide rails, two sectors are combined in an independently total framework, and other parts such as other drive spindle are installed on it and form independently two oar devices and various existing ship's and crafts coupling.

Take a broad view of paddle of all times, conquer the lively dragon boat race of line-of-battle ship, once every year compelling rowing regatta of Oxford and Cambridge or folks of china of Egyptian extremely hundred grand people's paddles from the Roman Empire, and single single-blade and single sculls all are with the hands directly to grasp oar paddling in water, we can say of all times, a basic sample does not have great changes and improvements.The present invention paddles in water automatically with two oars that manpower drives in two oar devices, does not need both hands directly to grasp oar, so just has a lot of advantages to display:

1, do not need the paddle skill, do not need group training, no matter man, woman, old and young, the many people of people are few, sitting posture, standing posture, as long as the two oars of paddling or the two oars of a plurality of series connection of putting forth one's strength together and can both accomplish synchronous entry, water outlet synchronously, and its working direction is sat to consistent, towards the place ahead with the paddler.

2, the side of a ship and waterline distance can design highlyer, and the beam also can design wider, so safety coefficient is big, can remove exercise, tough team will and the adventurous spirit that especially can cultivate the young people among great river, sea.
