Detailed description of the invention
Linkage type joint 1 as shown in Figure 1-2, in order to can pivotable, connect one first rod member 2,1 second rod member 3 and one the 3rd rod member 4 to interlock and locking, comprise socket joint 10,1 first double-action plate 11 and one second double-action plate 12.
Wherein socket joint 10 is fixed on the end of the first rod member 2, is provided with axle center 100 and a linkage pin 101 in inside, and makes linkage pin 101 can come and go the movable effect producing interlock first double-action plate 11 and the second double-action plate 12 along fixing path 143.
First double-action plate 11 is provided with one first axis hole 110 and one first skewed slot 111.Axle center 100 is utilized to be hubbed in socket joint 10 through the first axis hole 110 during combination.First double-action plate 11 one end of the present embodiment is exposed and affixed with the second rod member 3, and linkage pin 101 abuts the movement on also edge slidably with the first skewed slot 111 through the first skewed slot 111.
Second double-action plate 12 is provided with one second axis hole 120 and one second skewed slot 121.Utilize axle center 100 through the second axis hole 120 during combination, and make the second double-action plate 12 parallel with the first double-action plate 11 and be hubbed at coaxially in socket joint 10.Second double-action plate 12 is also that one end is exposed and affixed with the 3rd rod member 4, and linkage pin 101 abuts the movement on also edge slidably with the second skewed slot 121 through the second skewed slot 121.
As Figure 4-Figure 6, when the second rod member 3 bears an external force and turns the first double-action plate 11, first skewed slot 111 of the first double-action plate 11 will make it to move along path 143 to dynamic linkage pin 101, and linkage pin 101 also supports dynamic second skewed slot 121 when moving and produces moment to the second double-action plate 12, second double-action plate 12 is rotated towards the direction contrary with the first double-action plate 11, thus interlock the 3rd rod member 4.
Better one, can be embodied as an arc groove by the first skewed slot 111 and the second skewed slot 121, and allows the position in arc misalignment axle center 100 of this arc groove, and cause one end of arc groove close to axle center 100, the other end is away from axle center 100.
Movable for guaranteeing that linkage pin 101 can come and go along certain path 143, a guidance device 14 can be established in socket joint 10 inside, linkage pin 101 can only be come and gone movable along fixing path 143 by its constraint.Better one, linkage pin 101 can be made can only to come and go activity in path 143 along a straight line by its constraint, reach the guidance device 14 of this object, a set pin 140 and a pair chip component 141 can be comprised, wherein set pin 140 disalignment 100 1 segment distance but parallel with axle center 100, path 143, two chip component 141 defining a straight line by this connects linkage pin 101 with one end respectively, and the other end also establishes an elongated slot 142 to be socketed on axle center 100 and set pin 140 in a movable manner respectively.Because linkage pin 101 drives by chip component 141, it is movable therefore can only to come and go along the straight line path 143 defined by axle center 100 and set pin 140.In addition the first double-action plate 11 and the second double-action plate 12 are respectively equipped with a long slot bore 116,126 and pass through for set pin 140, stop when avoiding rotating by set pin 140.
As shown in figures 1 to 6, for making the first rod member 2, second rod member 3 and the 3rd rod member 4 are fixed on a state of opening 300, a flexible latch 15 can be comprised in socket joint 10, and establish one first recess 115 at the first double-action plate 11, second double-action plate 12 establishes one second recess 125, because flexible latch 15 is by elastic parts 16 bias voltage, therefore can automatically snap in therebetween when the first recess 115 and the second recess 125 provide jointly during enough gaps, make the first double-action plate 11 and the second double-action plate 12 cannot relative to socket joint 10 pivotable, thus make the first rod member 2, second rod member 3 and the 3rd rod member 4 are fixed on a state of opening 300.
Aforesaid flexible latch 15 and driver train 17 interlock, wherein driver train 17 is located at outside socket joint 10, be can pass through a flexible component 170 when operating and pulled flexible latch 15, make flexible latch 15 recess the first recess 115 and the second recess 125, thus allow the first rod member 2, second rod member 3 and the 3rd rod member 4 be able to mutual interlock and be pivoted relative to each other to one each other pivot close state 400.
First double-action plate 11 of the present embodiment and the second double-action plate 12 can select metal stamping manufacture, to provide strong characteristic, if but both directly overlap combination in socket joint 10, gradually sharp-pointed noise is produced in operation for a long time most probably with rubbing mutually afterwards, or because of combination after each other excessive clearance and cause each rod member 2,3,4 in rotation always not controllably a left side shake right rolling, reduce quality; In view of this, implementer with reference to shown in figure 2, can set up a pourable resin chock 18, uses gap of preventing between the first double-action plate 11 and the second double-action plate 12, and avoids the first double-action plate 11 directly to contact with the second double-action plate 12 and rub each other, produce noise.
As is seen in figs 7-10, linkage type joint 1 of the present utility model can be applicable to the locking of perambulator and pivot is rolled over, and wherein the first rod member 2 can be the rear foot tube of perambulator, and the second rod member 3 can be the handspike of perambulator, and the 3rd rod member 4 then can be the front foot pipe of perambulator.
Driver train 17 can be fixed on cross bar on perambulator or device at handspike, through flexible component 170 and flexible latch 15 interlock.Operator utilizes after driver train 17 removes the lock-out state in linkage type joint 1, handspike can be pressed down make to close towards rear foot tube pivot, at the same time through the interlink function in linkage type joint 1, front foot pipe also will be closed towards rear foot tube pivot, finally reach the state 400 of the conjunction of pivot each other as shown in Figure 10 and complete folding.
