Description
The present invention relates to hang the overhang-door to be opened/closed on the upper rail that is located to tilt slightly, particularly the check mechanism of this overhang-door.
Semi-automatic lift gate is meant the overhang-door with overhang-door energy automatic closing function of opening with hand push, is the self-closing device that keeps clockwork spring in adopting in the prior art, and overhang-door can be drawn by this self-closing device rope and close.When closing for and doorframe between do not produce impact, for can close and snubber is installed quietly.In the semi-automatic lift gate as check mechanism,, can change closing velocity with this Mainspring type self-closing device and air-cylinder type snubber, realize closing quietly by the elastic force of regulating clockwork spring or the air discharge of moderately setting snubber.
But, having the semi-automatic lift gate of above-mentioned self-closing device and snubber, its cost of manufacture height, and fault is many is so semi-automatic lift gate in recent years adopts to hang oneself at the inclination rail more is established the pattern of overhang-door.That is the overhang-door of, opening can utilize its deadweight to close by oneself.At this moment, overhang-door is walked along the upper rail that tilts, the result, and speed increases gradually, doorframe is produced impact, and the generation for fear of impacting is installed with check mechanism.
Fig. 4 represents to have the semi-automatic lift gate device of check mechanism.The upper end of overhang-door (Ren) is installed with hanging wheel (ロ), (ロ), and hanging wheel (ロ), (ロ) are positioned in upper rail (Ha) and go up and the overhang-door that plays (Ren).The direction that upper rail (Ha) is closed towards overhang-door (Ren) tilts, so, even do not adopt the such Mainspring type self-closing device of prior art, overhang-door (Ren) also can be closed, but, impact and collision doorframe (two) in order not produce in the moment of closing, check mechanism (ホ) is housed.
This check mechanism (ホ) is installed on the suspender (ヘ), and hanging wheel (ロ) is installed on the suspender (ヘ), and this check mechanism (ホ) has pinion (ト).This pinion (ト) though can rotate since check mechanism built-in viscous fluid, so its rotation is produced resistance, this pinion (ト) and tooth bar (チ) engagement.That is,, the overhang-door (Ren) that slides is played braking action by meshing with tooth bar (チ).
But in the semi-automatic lift gate device that upper rail (Ha) tilts slightly, if the gradient of this upper rail (Ha) is certain, then working as overhang-door width and weight thereof is a timing, and the closing velocity of overhang-door (Ren) is determined naturally.Certainly, if strengthen the angle of inclination of upper rail (Ha), then above-mentioned closing velocity strengthens, in the same manner, if strengthen the overhang-door width, the door travel distance lengthening of walking to and closing then from full-gear, speed increases.In addition, if strengthen overhang-door weight, the kinetic energy that obtains based on walking then, closing velocity increases.
But, correspondingly regulate the angle of inclination of upper rail (Ha) according to overhang-door width and overhang-door weight, be do not allow facile.In addition, though can regulate closing velocity by the viscosity that changes the viscous fluid in the pinion,, the kind that change viscous fluid accordingly with each overhang-door is unpractical.And the management also be not easy, in 0.5 °～10 ° model scope, it is difficult finely tuning in this scope again usually at the angle of inclination of upper rail (Ha).
Overhang-door (Ren) is wished not produce impact and is not produced bounce-back when closing.And wish closing velocity to be transferred fast or slow.For example, in house for the elderly and hospital etc., require to close than general overhang-door slowlyer.Though can regulate the closing velocity of overhang-door (Ren) by the axle moment of torsion that changes above-mentioned pinion (ト), because the length of tooth bar is inappropriate, so almost be the state that can not regulate.
Therefore, tilt at upper rail, with the semi-automatic lift gate device of rack and pinion mechanism as check mechanism in, exist the problems referred to above.The present invention is in order to address this problem, even providing a kind of overhang-door width and overhang-door weight to change does not produce impact yet, do not rebound, can close fully and check mechanism can regulate the semi-automatic lift gate of closing velocity in preset range.
Semi-automatic lift gate of the present invention hangs on the upper rail that is located at inclination, can utilize deadweight automatically to close, and this point is identical with prior art.In the present invention, along on the overhang-door of upper rail walking, adopt rack and pinion mechanism as the check mechanism that plays braking action, tooth bar is installed on rail-sides, and pinion is installed on the overhang-door side, this tooth bar and pinion.
Adopt the check mechanism of this rack and pinion mechanism, though do not have novelty, but among the present invention, suitably change by making tooth bar length, overhang-door can not produce impact, run into that doorframe does not rebound and can and not leave between the doorframe and close with gap owing to not exclusively closing, simultaneously, can regulate closing velocity (shut-in time).That is, if big (width is big) and heavy overhang-door, then because the kinergety when closing is big, the tooth bar that then extends, otherwise for little (width is little) and light overhang-door then shortens tooth bar length.
Among the present invention, during decision tooth bar length, determine to close range index (A) and overhang-door ponderal index (B), the above-mentioned range index of closing the when displacement from the full-gear to the full closing state is 1200mm is decided to be A=1, overhang-door ponderal index B=1 is decided to be 400mm with tooth bar length.At this moment overhang-door is to use the steel surface material of 0.8mm thickness, if then take advantage of 0.7 coefficient during the face side material.This numerical value of above-mentioned 400mm is the result of test of many times.When the size variation of overhang-door, A and B become and the value of closing apart from 1200mm composition relation, and the size that A * B * 400 are obtained is as tooth bar length.
On the other hand, also can be only corresponding to overhang-door weight ground decision tooth bar length.That is, if weight is big, then width is big inevitably, so distinguish overhang-door weight, sets the tooth bar length that is suitable for it.The upper-lower position of this tooth bar can be regulated, and makes the engagement of it and pinion flexible.

Fig. 2 is the axle moment of torsion of closing the corresponding pinion of distance with overhang-door.
Fig. 3 is the detail drawing of check mechanism.

Below, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is embodiments of the invention.The check mechanism of band rack and pinion mechanism is housed on the overhang-door device.Overhang-door 1 hangs and is located on the upper rail 2, in overhang-door 1 upper end suspender 4 is installed, and this suspender 4 has the roller 3 that rolls on upper rail 2.Upper rail 2 has 0.5 °～1.0 ° angle of slope, with prior art similarly in front of the door side slightly the lowland at a slant, so, can automatically close under the deadweight effect with the overhang-door 1 that hand push is opened.
On the suspender 4 of this overhang-door 1 pinion 5 is installed, tooth bar 6 is located at the upper rail side along these upper rail 2 edges.Pinion 5 has check mechanism, and this check mechanism is being accommodated viscous fluid, and (for example silicone oil #6000～#8000), pinion 5 is subjected to the resistance of viscous fluid when rotating.Pinion 5 and tooth bar 6 engagements before overhang-door 1 is closed, the result, though pinion 5 rotations, its rotational resistance suppresses the translational speed of overhang-door 1.
Overhang-door 12 moves from full-gear along upper rail, and by pinion 5 and tooth bar 6 engagements, the performance braking action can be closed quietly, but at this moment, weighs if this overhang-door 1 is big and when the distance W of closing fully was big, then kinergety was big.Otherwise if the weight of this overhang-door 1 is little, when half-open position was closed, the kinergety during with tooth bar 6 engagements was little.The present invention considers this point, decision tooth bar length, and in its scope, have the amplitude of accommodation.
With overhang-door 1 from the full-gear to the buttoned-up status apart from 1200mm as benchmark, establish at this moment effectively close range index A=1, overhang-door ponderal index B=1, tooth bar length L=400mm.Promptly, tooth bar length 400 when closing distance for 1200mm, be based on the value of test of many times, has the overhang-door that other closes distance and weight, can be benchmark with this 1200mm, range index A and overhang-door ponderal index B are closed in relation decision in proportion, multiply by 400 numerical value after this two index is multiplied each other again as tooth bar length.Table 1
| Close distance | Close range index | The door ponderal index | Tooth bar length |
| ????W | ????A | ????B | ?L=A·B·400 |
| ????1200 | ????1 | ????1 | ????400 |
| ????1050 | ????0.87 | ????0.87 | ????300 |
| ????900 | ????0.75 | ????0.75 | ????200 |
| ????750 | ????0.62 | ????0.62 | ????150 |
It is 1200,1050,900,750 o'clock situation that distance is closed in table 1 expression, with 1200 be benchmark determine other close range index A and overhang-door ponderal index B.Closing distance is 1050 o'clock, and from A=1 * 1050/1200, B=1 * 1050/1200 calculating formula is asked calculation, obtains A=0.87, B=0.87.Tooth bar length L=400 * 0.87 * 0.87 ≈ 300.Closing distance is 900 o'clock, L ≈ 200, and closing distance is 750 o'clock, L ≈ 150.
Actual tooth bar length L is to be benchmark with numerical value shown in the table 1, regulates ground and use in the scope of 10% front and back.At this moment overhang-door 1 adopts the plate of pasting the thick surperficial material of 0.8mm, if wood based panel, then overhang-door ponderal index B is about 70% of steel plate, and tooth bar length also is about 70% in the table 1 and gets final product.Tooth bar 6 adopts resin forming product, cuts into the Len req use being configured as the long tooth bar 6 of 400mm.
Like this, determined to close the corresponding tooth bar length L of distance, used this tooth bar, regulated the axle moment of torsion of pinion with overhang-door weight and overhang-door.Fig. 2 represents the axle moment of torsion (axle rotational resistance) with respect to the pinion check mechanism of closing distance of overhang-door 1, and A represents that from full-gear to closing, B represents from half-open position to closing.From this figure as can be known, when closing distance when big, the speed height during with tooth bar 6 engagements, therefore the axle moment of torsion increases, and braking effect is big.Otherwise when closing distance hour, the speed during with tooth bar 6 engagement is little, and the axle moment of torsion of pinion diminishes.Equally, in full-gear and half-open position, even close the big overhang-door of distance, little from the speed with tooth bar 6 engagements of half-open position, the axle moment of torsion is inevitable little as a result.
Therefore, in fact regulate with the C state.If near A, overhang-door produces the situation that can not shut fully, otherwise if near B, then the axle moment of torsion is too small, and the overhang-door of running into doorframe produces rebound phenomena.But, among the present invention,,,, can shorten 2.37 seconds under the fast situation based on a reference value so the adjustable range of overhang-door shut-in time is big owing to adopt the tooth bar that is suitable for overhang-door, can extend under the slow situation 12.2 seconds.This adjustable range is compared with prior art very big, and the overhang-door of hospital and house for the elderly etc. is preferably closed at leisure, and the present invention can satisfy this requirement.
On the other hand, among the present invention, also can only be conceived to overhang-door weight and decide tooth bar length.That is, inevitable overhang-door width was also big when overhang-door weight was big, and overhang-door weight is directly proportional with the overhang-door width.Therefore, overhang-door weight be divided into below about 23 kg, about 23 kg～about 32 kg, such three classes more than about 23 kg.Overhang-door for below about 23 kg is decided to be about 200mm to tooth bar length; Overhang-door for about 23 kg～about 32 kg is decided to be about 300mm to tooth bar length; Overhang-door for more than about 32 kg is decided to be about 400mm to tooth bar length.
Modulus with the pinion of tooth bar engagement is decided to be 3.Be decided to be 3 by the modulus pinion, can be suppressed at Min. by the impulsive sound when meshing with tooth bar, and can strengthen the back lash of rack and pinion, the adjusting transfiguration during construction is easy.Usually, modulus is big more, and is big more with the sound of tooth bar engagement, and modulus 3 can satisfy the inhibition of this engagement sound simultaneously and the such two aspect requirements of adjusting when constructing.For example, if modulus is 1.5, though the engagement sound reduces, adjustable range is-0.5～+ 0.5, and modulus is 3 o'clock, and adjustable range is-1.5～+ 1.5.
Fig. 3 represents check mechanism, and this suspender 4 is installed in the upper end of overhang-door 1 to 3 on roller, and the check mechanism 7 of built-in toughness fluid is installed on this suspender 4 on suspender 4, is fixing pinion 5 from the axle head that check mechanism 7 extends.Tooth bar 6 is installed on guide rail platform 8, and this tooth bar 6 is installed on the installation tool 9 that is L type section.Tool 9 is installed is fixed on the guide rail platform 8, but its upper-lower position can be regulated.That is, because the employing modulus is 3 pinion 5, so can in-1.5～+ 1.5 scope, regulate the upper-lower position of tooth bar 6.
As mentioned above, semi-automatic lift gate check mechanism of the present invention according to the weight decision tooth bar length of overhang-door, simultaneously, can be regulated the upper-lower position of tooth bar, has following effect.
In the semi-automatic lift gate device of the present invention because according to overhang-door weight decision tooth bar length, so, the overhang-door that is open under its deadweight effect when the inclination upper rail is closed, can close quietly.That is to say, can close with not impacting doorframe, and also do not rebound when running into doorframe, and do not have owing to close by halves and have the problem in gap between the doorframe.In addition, be decided to be 3, can suppress the engagement sound with tooth bar, simultaneously, can regulate the tooth bar position during construction by modulus pinion, flexible with the engagement of tooth bar.
