Description

The lid of peristome support arm positioner

The present invention relates to the lid support arm positioner that a kind of open and close are called the peristome of high residential building scavenge port etc.

As shown in Figure 3, at existing support arm positioner, the limit of lid B is fixed on the fixed frame A of peristome by pivot 1, the base end part of stayed pole 5 is fixed on the pars intermedia that covers B by the bearing pin 13 parallel with pivot 1, leading section at stayed pole 5 is provided with active pin shaft 8, active pin shaft 8 is inserted in slidably along in the guide slide 20 of the lateral margin setting of fixed frame A, is provided with groove 21a, 21b, the 21c of active pin shaft 8 combinations, separation at the lower side of guide slide 20.

This existing apparatus, when closing cap B, must start slightly and cover B to make it be center rotation with pivot 1, from groove 21a or 21b, take active pin shaft 8, pulling stayed pole 5 makes its free end 4 one sideway swivels to lid B, makes active pin shaft 8 be in free state in guide slide 20.

And cover B to make it be the center rotation with pivot 1 opening also must start for the time being when covering B, make active pin shaft 8 from from pivot 1 groove 21c farthest, deviating from, the position of control stayed pole 5, make active pin shaft 8 be in free state in guide slide 20, its operation of any action of Kai Heguan all is pretty troublesome.

In addition, make stayed pole 5 rotation, when removing the engaging of active pin shaft 8 and groove 21a, because the object of B is not covered in supporting, so lid B can naturally and understandably shut quickly, the danger of a part of clamping health is arranged, when lid is embedded with glass etc. on the B, sometimes because the impact during scram also damages glass etc. possibly.

Proposed recently on high residential building, the scheme of scavenge port has been set,, therefore required easy and simple to handlely, be safe from danger because senior people and junior might remove the window lid of this scavenge port of open and close in wall to the part on floor in each room.

Therefore, the lid support arm positioner that the purpose of this invention is to provide a kind of peristome, this device is owing to the end at the open and close stroke that covers, the groove that does not have active pin shaft engaging, thus the open and close that just can cover easily with once-through operation, and, even temporarily having what external force to act on covers, the danger that does not also have lid naturally and understandably quickly to close, and simple in structure, almost do not worry and can break down.

Lid of the present invention support arm positioner at one end is bearing in inner surface 2 one sides of the lid B on the fixed frame A of peristome P with pivot 1, be provided with from the outstanding to the inside side plate 3 of lid B inner surface 2.On side plate 3, the base end part of support arm 5 uses the bearing pin 6 parallel with above-mentioned pivot 1 to be bearing in end near the free end 4 of lid B.On said fixing frame A, be provided with the plane arranged perpendicular that comprises peristome P, to the fagging 10 that erects of inner surface 2 of lid B.

On fagging 10, be provided with inclined elongate 7, the end of the pivot 1 of this slotted hole 7 its close lid B is away from the inner surface 2 of lid B, on the other hand, near the end approaching lid B of the free end 4 that covers B, the active pin shaft 8 that can slide in inclined elongate 7 is fixed on the front end of above-mentioned support arm 5.

The extension spring hook plate 9 that can rotate freely around its axis is installed on active pin shaft 8, protrudes in the end of the fagging 10 of side plate 3, be provided with the hook portion 11 of hanging spring at free end 4 to lid B.One end of draft helical spring 12 is hung on the spring hook plate 9, the other end of spring 12 is hung on the spring hook portion 11.

Under the state of complete closing cap B, above-mentioned bearing pin 6 is positioned at a side of covering B about the center line 0 by active pin shaft 8 and the above-mentioned spring 12 of hanging spring hook portion 11, and effect has the spring force of spring 12 on the direction of closing cap B.

Fig. 1 is the lateral view of the lid of one embodiment of the invention with the support arm positioner.

Fig. 2 is the longitudinal sectional view of the lid of Fig. 1 with the part of support arm positioner.

Fig. 3 is the lateral view of existing apparatus.

As depicted in figs. 1 and 2, for the part that has illustrated in front, this part of repeated citing and omit its explanation in addition.

The side plate 3 of lid B and the fagging 10 of fixed frame A are made with solid corrosion resistant plate usually, but also can with the engineering plastics plate.Be formed at the angle of slope of the inclined elongate 7 on the fagging 10, the opening surface that covers B relatively is that 15 degree are to 30 degree.

Strut 5 becomes with the Design of length of inclined elongate 7: when complete closing cap B, near the low-end 7a of active pin shaft 8 arrival inclined elongate 7, on the other hand, covering the B complete opening under the state of predetermined angular, promptly be opened to when leaving actinal surface about 45 and spending at lid B, active pin shaft 8 arrives the high terminal 7b of inclined elongate.

Be in the bearing pin 6 that covers under the B buttoned-up status, the side of lid B that be positioned at the central axis 0 at the two ends that connect spring 12, promptly connects active pin shaft 8 and hang the straight line of spring hook portion 11, therefore, spring 12 has spring force to opening the directive effect of covering B, a kind of booster when covering B for opening.

The lid of Gou Chenging support arm positioner like this, when lid B complete closed peristome P, lid B by the blocking device relative fixed frame A that installs by other approach with its locking.

If remove the locking that realizes by above-mentioned blocking device, then by the post-equalization power of spring 12, active pin shaft 8 is pulled to extension spring hook portion 11 1 sides of fagging 10, owing to the position that is poured onto at its initial stage support arm 5 near level, so, give with bearing pin 6 parts, upward to component less, lid B begins slowly to open, active pin shaft 8 slowly moves in inclined elongate 7 at a slant upward.

Along with moving of active pin shaft 8, lid B is the center by support arm 5 and side plate 3 with above-mentioned pivot 1, and to rotation counterclockwise, active pin shaft 8 is met the high terminal 7b of inclined elongate 7 in Fig. 1, therefore covers the enable possition that B is parked in regulation.

Even in the position of opening, enough pulling force that spring 12 also is necessary, lid B can remain on opening exactly.So, because lid B has the trend to the rotation of the direction opened all the time, so, even the people touches or high wind etc. acts on and cover on the B, cover B and also can by mistake not be closed.

Secondly, when closing cap B, can ride on the free end 4 that covers B by hand, the spring force of resistance spring 10, toward lower cover B, making it is the center rotation with pivot 1.By this operation, active pin shaft 8 is extension spring 10 on one side, inclined elongate 7 in downwards move on one side, near the arrival low-end 7a.At this moment, B is parallel with peristome P for lid, and with its locking, lid B is latched on the fixed frame A once more by above-mentioned blocking device.

As previously discussed, lid of the present invention support arm positioner, if remove the blocking device of installing by other approach, then covering B can be owing to the spring force of spring 10 automatically to the direction rotation of opening, on the other hand, when closing, be not only thrust cap B simply, also do not had the operation of the stayed pole of trouble resemble the existing apparatus, so, the open and close operation of lid B is even senior people or junior can both finish by once-through operation extremely simply.

In addition,, cover the enable possition that B can stably remain on regulation because spring 12 makes the trend that B has rotation of cover, so, do not blown and cover B and shut unintentionally by wind one, clamp the danger of the part of health.

In addition,, can carry out simultaneously, can under the situation of the rotational resistance that appropriateness is arranged, continue to carry out with extension spring 12 because swivelling cover B is its locking, so,, the locking rapidly of lid B do not cover the danger that B or damage are embedded in the glass that covers on the B etc. because impacting to damage.
