The specific embodiment

The present invention will be described in more detail for embodiment shown in below inciting somebody to action with reference to the accompanying drawings.

Fig. 1 is the decomposition diagram according to hinge means of the present invention.Fig. 2 is the part sectioned view of observing above of the occasion that is suitable for according to basket KT and door D1 to furniture etc., and shows action.Fig. 3 to Fig. 6 is the part sectioned view to being arranged on the mechanism in the 4th chain link of the present invention and this action being described.Door D2 shown in Figure 2 is the door in abutting connection with furniture.

Below, each component parts of hinge means and the situation of interconnecting are described mainly with reference to Fig. 1.Being fixed on the basket side group KB of portion on the basket of furniture etc. is the cross section that the upper side member KB2 of Contraband font covers on the inboard that section is the lower side member KB1 of Contraband font on direction as shown, and logical (following each pin illustrates omission too) pin P0 of each hole interpolation of portion's setting at one end as pivot.And when using 3 screw N1 to be fixed on the basket, making up and down, the globality of parts is strengthened.And the interior plate parts KTA (Fig. 2) at the medial surface of the sidewall that forms basket KT uses N2 pair of lower side member corresponding with fixing upper side member of another screw to carry out the height adjusting.And, to the position relation of using another screw that upper side member and lower side member are regulated, use one of them of 3 screw N1, as shown in Figure 2, the screw N1 that promptly is positioned at the rightmost side fixes.

The other end of the lower side member of the above-mentioned basket side group KB of portion is provided with hole P1AH, in this end scope of the other end no show of upper side member.Therefore, making the cross section is the inboard that the end L1A of the 1st chain link L1 of Contraband font is positioned at this lower side member the other end, under the state that hole and above-mentioned hole P1AH are matched, inserts logical pin P1A.And, make the end L2A of the 2nd chain link L2 be positioned at the inboard of the other end L1B of the 1st chain link, pin P2A is inserted logical each hole that is provided with.And, make the other end L2B of the 2nd chain link, as described below, be positioned at the inboard of open side end (left part of Fig. 1) of the reveal base portion DB of the accommodation space SP that is provided with as shown in the figure, and make pin P2B insert the logical hole that is arranged in two parts.

And, the end of the 2nd chain link L2 and the pars intermedia of the other end also are provided with the hole, make the 2nd chain link be positioned at the inboard of the 3rd chain link L3 of shape as shown in the figure, the hole of the pars intermedia of above-mentioned the 2nd chain link is matched with the hole that is located at the central portion of the 3rd chain link, and insert logical pin P3C.And, near the above-mentioned hole P1AH of the other end side of the lower side member KB1 of basket side group portion, be provided with another hole P3AH, make the end L3A of the 3rd chain link L3 be positioned at the outside of this lower side member the other end, under the state that the hole that makes the 3rd chain link one end and above-mentioned hole P3AH match, insert logical pin P3A.And the 3rd chain link has also can make the 1st chain link be positioned at the inboard width dimensions of its inboard.And, in order to make the 1st chain link and the 2nd chain link the 3rd chain link inside of coming in and going out, be provided with big peristome L3K at upper lateral part.The following side is opened wide comprehensively.

Making the cross section is the inboard that the end L4A of the 4th chain link L4 of Contraband font is positioned at the other end L3B of the 3rd chain link, and pin P3B is inserted each hole that the reduction of fractions to a common denominator is not provided with.Make the other end L4B of the 4th chain link be positioned at the inboard of above-mentioned reveal base portion DB, pin P4B is inserted the hole of logical this other end, and the hole that in bearing JB and bearing JB ', connects formation, bearing (JB) is set at the length direction central portion (the left and right directions central portion of Fig. 1) of reveal base portion, and bearing JB ' is the bearing with the left and right end portions of this bearing JB adjacency.

And above-mentioned the 4th chain is equipped with: the 1st compacting part M1; As the helical spring R that composes gesture parts one example; And the 2nd compacting part M2, it rotates with the 4th chain link.That is: the 2nd compacting part M2 is provided with through hole P3BH, sets this through hole in the 4th chain link, and the 3rd chain link and the 4th chain link are inserted logical above-mentioned pin P3B together.This through hole is the slotted hole on the direction of being composed gesture by helical spring R, and this long axis length grows the above length of regulation than the diameter of pin P3B.

The other end side of the 4th chain link sets the 1st compacting part M1, sets helical spring R between the 1st, the 2nd compacting part, often composes gesture on the direction that these parts are separated from each other.In this case because the top of the 1st compacting part M1 contacts with the bearing JB of above-mentioned reveal base portion, even thereby by helical spring tax gesture, this position also can keep.Followingly the action specification of these compacting parts is set forth with reference to Fig. 3 to Fig. 6.

The notch K3A that is located at the both sides board of the 1st chain link is the former of K3C, under the situation that door D1 (hinge means) opens fully, the 1st chain link is contacted with pin P1A, help to stop opening action, in complete opening procedure, help to prevent that the 1st chain link from disturbing pin P1A conversely speaking.Latter K3C helps to prevent that the 1st chain link from disturbing pin P3C before door D1 (hinge means) closes fully.And the notch KJB ' of the lower edge central portion of the both sides board of the 3rd chain link L3 helps to prevent that the 3rd chain link from disturbing the bearing JB ' of the left and right end portions of reveal base portion DB before door D1 closes fully.And near the notch K2B the end L3A helps to prevent that the 3rd chain link from disturbing pin P2B before door D1 closes fully.

Fig. 2 shows above-mentioned hinge means and is installed between basket KT and the door D1 and the complete closing state of door, and shows full open position with two chain-dotted lines.At first, the basket side group KB of portion must be embedded in the outer panel parts KTB of the lateral surface that forms the basket sidewall and form between the medial surface of interior plate parts KTA, that is: be mounted to prevent to be projected into accommodation space from medial surface.

On the other hand, reveal base portion DB is installed in a D1 place.The reveal base portion must be embedded in the outer panel parts D1B of the lateral surface that forms door and form between the medial surface of interior plate parts D1A, that is: be mounted to prevent to be projected into accommodation space from medial surface.Specifically, the insertion of reveal base portion is arranged in the hole of interior plate parts D1A, under the state of the edge part that its flange part FR is installed to the hole, fixes with screw.

When door D1 closed fully, the 1st～the 4th chain link shown in Figure 2 was folded, and is contained in the accommodation space SP of reveal base portion.In this routine hinge means, the flange part external surface of relative reveal base portion, integral body is all held.If strict expression, though can be expressed as: only the thickness of flange part part is projected into basket accommodation space side from the medial surface of the door of the interior plate parts D1A of formation door, in fact, we can say not to be projected in the accommodation space.In the inboard of the 3rd big chain link,, form the state that is contained substantially though other each chain link of the 1st, the 2nd, the 4th has part to come in and go out.And at this moment, because the width of the 2nd chain link is the size that is accommodated in the inboard of the 4th chain link, thereby the part of the 2nd chain link enters the inboard of the 4th chain link, thereby can not produce interference.

State in the marginal portion (mean and contain the contact rubber components) of a distolateral collision basket of door is under the complete closing state, the 1st chain link L1 at notch K3C near pin P3C.The 3rd chain link L3 near pin P2B, and locates bearing JB ' near the left and right end portions of reveal base portion DB at notch KJB ' at notch K2B place.And, by the side plate lower edge of the other end L3B of the 3rd chain link bottom surface near reveal base portion DB.And the 4th chain link L4 is near the bottom surface of reveal base portion DB.

The state (2 chain-dotted line state) that door is opened fully can be described as the roughly aperture of 180 degree as shown in the figure.For the critical piece that under this state, moves, with move before added in the identical mark ' mark.Under this state, the 1st chain link L1 ' locates to contact with pin P3A at notch (K3A).And the 3rd chain link L3 ' contacts with pin P2B '.According to the exposure level in these two places, door stops in the apertures of 180 degree substantially, and can not open bigger aperture, thereby prevents to disturb the door D2 of the basket of adjacency.

In this plan view shown in Figure 2, constitute according to each parts of hinge means of the present invention and also be not projected into inboard (accommodation space side) from the extended line in the place ahead of the interior plate parts KTA that forms basket.Therefore, the A/F of basket is dwindled, can use safely, and the operation of the accommodation space of object turnover basket inside can be carried out smoothly.

More than Shuo Ming hinge means according to the present invention is the mechanism of the inboard of an a kind of end L2A with the 2nd chain link L2 the other end L1B of being arranged on the 1st chain link L1, although is the same and be arranged on the outside with the relation of other chain links, yet each action effect illustrated in fig. 2 proves effective too.But because above-mentioned the 2nd chain link is provided in the inboard of the 1st chain link, and the width of the 2nd chain link is the size that is contained in the inboard of the 4th chain link, thereby under the situation of closing, the part of the 2nd chain link enters the inboard of the 4th chain link, and the explanation of not disturbing will change.Promptly change as follows: the width of the 2nd chain link can be formed to such an extent that can make the 4th chain link be positioned at the inboard of the 2nd chain link, perhaps, can form the width of same degree, and form of being pruned in the interference position of arbitrary chain link etc.

Secondly, even setting of the 1st chain link and the 2nd chain link concerns it is arbitrary occasion in above-mentioned inboard, the outside, the action of the mechanism of the following Fig. 3 to Fig. 6 of reference is also set up.

Fig. 3 is a closing state, in Fig. 2, represents the occasion of the state of door with solid line that is:, and dissects represented occasion to being provided in the mechanism in the 4th chain link and the part of reveal base portion.And Fig. 4 is state and the figure corresponding with Fig. 3 that door is opened fully.The outer peripheral face CS that pin P4B inserts logical bearing JB is that the center with the hole of latch nail usefulness is the part (being the part of periphery) of the circle at center.

Under the state that door is opened fully, corresponding with the position of the 1st compacting part M1 in the 4th chain link, be provided with the 2nd recess K2 at the bearing outer peripheral face of circular arc.And, corresponding with door closure state, be provided with the 1st recess K1 at the bearing outer peripheral face of circular arc.And the top of the 1st compacting part M1 forms such as oval and parabola shaped etc. substantially smooth taper shape.

Therefore, if before door is closed fully, the aperture that just is closed to door is the position before the 25 degree degree, and thereafter, the 1st compacting part M1 that is composed gesture by helical spring R slips in (falling into) the 1st recess K1 naturally, and thus, door can be introduced automatically and can be closed fully.This need not to come the final plant closure door by staff with regard to making, thereby simple and convenient, but also produces following effect, can prevent that promptly Yin Men from closing the too quickly big sound that produces, and can realize quiet closing.And the 1st recess and the 1st is because the fastening of compacting part makes the mobile of the 4th chain link be controlled, thus can prevent since pent door because vibration etc. and unlimited accidentally rocking of being produced.

When opening, (near 180 degree) remain before door is opened nearly fully, and the 1st compacting part M1 begins to slip into the 2nd recess K2, slips into automatically afterwards, and thus, door becomes the state of opening fully.Then, because the fastening of the 2nd recess and the 1st compacting part makes the mobile of the 4th chain link be controlled, thereby can prevent that the door of opening fully from moving rocking of being produced accidentally owing to vibrate on the direction of closing.

The above-mentioned item that describes with reference to Fig. 3 and Fig. 4, as shown in Figure 3, even take off accessory plate parts HB, and even without the 2nd compacting part M2, as shown in Figure 5 and Figure 6, installation process too.The installation situation of accessory plate parts and the 2nd compacting part M2, as described below, in the process of introducing automatically on the direction that propylaeum is closed fully, it is different once stopping this situation.

Back side assigned position at accessory plate parts HB is provided with buckling parts TA, and it can fasten, break away from the notch TA ' that is located at reveal base portion DB, and the accessory plate parts can be loaded and unloaded.And the assigned position of front is provided with the chevron protuberance TB as buckling parts, and under the state that is installed in the reveal base portion, if make on the open side of this accommodation space SP and make bottom surface side downward, then the accessory plate parts just can be mounted at upper and lower and extend upward.The upper side KK of protuberance mean near with the surface of the accessory plate parts direction that is orthogonal, thereby form with the high-dipping angle, its downside surface YK forms with the gentle dip angle.And the height dimension of protuberance is meant below the length of the diameter that deducts pin P3B the long axis length (major axis footpath) of the through hole P3BH in being located at above-mentioned the 2nd compacting part M2.

With reference to Fig. 5, under the state that the accessory plate parts are housed, as closing door, the position before closing fully then, the position of 25 degree degree for example, by aforesaid mechanism, the door beginning is closed automatically.But, before closing nearly fully, for example, be the position of 5 degree degree in door aperture angle, the 2nd compacting part M2 tangles the high-dipping face KK of protuberance, and the motion of door is stopped for the time being.After this, if according to the rules regulation try hard to recommend door, then the 2nd compacting part since the tax gesture of opposing helical spring R retreat, and with the fastening disengagement of protuberance.Thus, door can be closed fully.

And oval and parabola shaped etc. smooth taper shape is for example roughly formed on the top of the 2nd compacting part, so that can make fastening disengaging with the high-dipping face of protuberance with specified force.By with the fastening of this protuberance, if stop to move of door for the time being, then can prevent a strong collision basket and produce big sound.After this, in order to cross this protuberance, when using specified force to promote when closed, because the movement angle little (5 degree degree) of door, thereby can not produce big collision sound.

With reference to Fig. 6, in the time will opening the door that is in closed condition, the 2nd compacting part M2 is positioned at the downside of protuberance, and in this case, YK contacts with the gentle dip face, because the angle of inclination is not steep, thereby can not produce big resistance, the 4th chain link can be crossed protuberance TB.Therefore, the inappropriate situation of opening door operation can not take place.But, as shown in Figure 3, use and still do not use the effect of this mechanism under the state that takes off the accessory plate parts, also can open and close according to user's hobby.

And, in the above description, the surface C S of bearing JB is circular-arc, in these two positions, be provided with recess K1, K2, but do not establish these, then the 4th chain link only with pin P4B as pivoted, have a kind of like this mechanism in the 4th chain link, promptly only make the 2nd push part M2 compose gesture as the helical spring of composing the gesture parts.On the other hand, the inboard of the basic DB of reveal also can be provided with the hinge means with raised part TB.

In this case, if the people wants to close to the doorstep, then before door was closed nearly fully, the 2nd compacting part and protuberance fastened, and this reduces the trend that door is closed at least.If the trend of closing is suitable, the trend of then closing the door temporarily stops, and will close fully if push away afterwards again.In a word, the present invention has and can prevent that door from producing the effect of big sound when running into basket edge etc.Protuberance TB is not formed in the accessory plate parts that can freely load and unload, but can the whole outstanding inboard that is formed on reveal base portion DB.

And, more than the common phase opposite house of Shuo Ming hinge means is arranged on two positions up and down, in this case, if the gap between left and right door is in the upper-lower position heterogeneity, then as mentioned above, use another screw N2 and regulate adjustable clearance by position to the lower side member of basket side group portion.And, in the above description, although be that sheet metal system furniture with steel etc. is that prerequisite describes, even wooden furniture etc. are also just the same, without limits.
