Description
Technical field
The present invention relates to a kind of chair type furniture, also relate to the metal assembly of this furniture.
Background technology
Have a kind of chair type furniture in prior art, feature has the pad leg Slab element be made up of a pad leg plate.Just moving to resting position when padding leg plate not in using state, being namely hidden in the below of sitting face.Can by padded for the leg of user thus feel more comfortable seated position if make this chair type furniture be in one, then need to use pad leg plate, at this moment just by a rotary motion, pad leg plate is moved to use location, be namely positioned at the prolongation also forming sitting face before sitting face to a certain extent.
For the chair type furniture of the pad leg plate with such a position changeable, problem is that the spatial accommodation below sitting face is limited, and process from use location to resting position that shift from of pad leg panel assembly the rotating range of process be limited equally.There is enough large size, thus by pad leg panel assembly that is padded for the leg of user, ride comfort when use location, because its length is difficult to too greatly the below being arranged in sitting face, have the danger of colliding with the base of ground or chair type furniture when rotary motion.
Chair type furniture according to the invention addresses this problem like this: the Design of length of pad leg plate becomes variable.Variable-length refers to pad leg plate relative to the longitudinal direction of use location towards furniture, and the bearing of trend being namely placed on the user's leg on pad leg plate is variable.
The variable-length of pad leg plate is achieved in that this pad leg plate has at least two metal assemblies, they can move towards two contrary relative shift directions along with the movement of pad leg plate, thus have different distances each other when pad leg plate is in resting position and use location.Usually, a linear guides is designed with between these two pad leg sheetmetal assemblies.
In order to the change in location by required pad leg plate length variations and pad leg plate, the change of especially padding leg plate position of rotation connects, and people have employed multiple different design.Starting point of the present invention is such one design, is namely designed with a spring assembly, and it has an elasticity sections that can directly or indirectly work between two pad leg sheetmetal assemblies.So just can apply direction opposite effect power constantly to these two pad leg sheetmetal assemblies, thus make it always have movement close to each other or mutually away from the trend of movement, so just make pad leg plate increase or reduce.This trend realized by spring assembly is limited by a controlling organization, the active force that it and spring apply has the opposite effect, be arranged on another pad leg sheetmetal assembly of chair type furniture, it also changes in the process padding the movement of leg plate with the relative position of pad leg plate, thus make pad leg plate reduce or increase at the active force that pad leg plate carries out overcoming in the process rotated elasticity sections towards first direction of rotation, the constantly movement of pad leg sheetmetal assembly is then being allowed towards the contrary direction of motion, thus make spring assembly pad leg plate can be increased or reduce according to its layout.
These are at least that the solution of state-of-the art also comprises and is designed with a metal coil spring, it between two pad leg sheetmetal assemblies, can extend towards furniture longitudinal direction.But result has shown that this design is problematic because need in actual applications two pad leg sheetmetal assemblies can the larger distance of relative shift, such as 20cm, but save installing space again due to spring, this cannot realize.Such as, helical spring is compacted when padding leg plate and remaining static, length is reduced to 5cm, reaches using state must to stretch 20cm to make pad leg plate.But for conventional helical spring, this will cause excessive tensile, thus causes helical spring permanent damages.As the replacement scheme of significantly draft helical spring in the above described manner, can use a kind of push and pull system, it works between two pad leg sheetmetal assemblies, thus can use a shorter spring and make the tensile elongation of this spring less.But such spring system has higher cost, and there is in Machine Design a series of difficult point.
Summary of the invention
The object of the invention is, a following design chair type furniture, it solves by very simple structural design the problems referred to above that existing design causes at least partly.
According to the present invention, this is realized by two embodiments, these two embodiments preferably common implementing, but also can implement one by one in principle, and each embodiment is applicable to solving basic problem.
According to first embodiment taked as suggested in the present invention, a kind of chair type furniture, comprise: a sitting face and a pad leg plate, the latter can be shifted between resting position and use location, when resting position, pad leg plate is positioned at below sitting face, and towards furniture vertical direction, when use location, pad leg plate is positioned at before sitting face, and towards furniture longitudinal direction, wherein:
Pad leg plate the first metal assembly of relative shift and the second metal assembly can form and pad leg plate variable-length by two,
Active force can be applied to the first metal assembly (30) and the second metal assembly by some elasticity sections of spring assembly, these elasticity sections work between two point of applications, first point of application is positioned on the first metal assembly, second point of application is positioned on the second metal assembly, it is characterized in that
On two pad leg sheetmetal assemblies, two point of applications are arranged with mutually staggering along furniture horizontal direction, thus elasticity sections is in a plane strutted towards the relative shift direction of furniture horizontal direction and two pad leg sheetmetal assemblies, and can diagonally extend.According to this aspect of the invention, padding between fixing point on leg sheetmetal assemblies, that be staggeredly arranged along furniture horizontal direction or turning point at two, elasticity sections works.Such as, first point of application on the first metal assembly can be arranged in the left side of furniture or pad leg plate, and second point of application on the second metal assembly is then arranged in the right side of furniture or pad leg plate.
The extension diagonally of elasticity sections will reduce necessary tensile elongation.Due in the process of the plate shortening of pad leg or prolongation, the point of application is only along the relative shift direction of pad leg sheetmetal assembly, instead of mutually move along the furniture horizontal direction rectangular with it, so just can use the spring that a tensile elongation is much smaller, and without the need to changing the external dimensions of pad leg plate.Such as use the metal coil spring towards diagonal, its tensile elongation increasing degree compared with its drift when padding leg plate and retracting is no more than 20%-30%, thus such as makes pad leg plate extend or shorten 20-30cm.No matter be that pad leg plate is in use location or resting position, metal coil spring can be arranged in the diagonal directions.But in principle, when use location and one of them position of resting position, two point of applications are in same height on relative shift direction, even if thus make elasticity sections also can close to towards furniture horizontal direction on such extreme position.
Further, advise elasticity sections to be designed to elastomeric spring, and first measure that this measure is best and elasticity sections is diagonally arranged is taked jointly.Contrary with the spring assembly usually adopted before, suggestion uses the spring assembly be made up of elastomeric material accordingly.Result shows, this spring assembly can have larger extensibility, is therefore very applicable to application purpose described here.Elastomeric material of the present invention refer to a kind of can the plastic base of elastic stretching and/or natural rubber sill.Preferably use a kind of composite, wherein inside a plastic casing, arrange many natural rubber driving-belts.So just can realize higher chemistry and mechanical stability, make spring assembly have good tensile properties simultaneously.Above-mentioned shell can be made with polyester material.In order to improve stability, inner driving-belt is preferably woven together or otherwise weave in.The elasticity sections adopting elastomeric material to make preferably realizes such tensile properties: when applying the active force between 20N-50N, length extensibility reaches 100%.
If elastomeric spring be designed to one surround the driving-belt of shape invariance, such as can surround circle, square or rectangle, then advantageously.So just can realize turning to easily, its advantage will be set forth later further.
Further, even if only have an elasticity sections, its one end is fixed on first pad leg sheetmetal assembly, the other end is fixed on second pad leg sheetmetal assembly, substantially the elastic force needed for can applying to two pad leg sheetmetal assemblies, but more preferred scheme is: at two pad leg sheetmetal assemblies, one of them is at least designed with two point of applications, and spring assembly has at least two elasticity sections, they especially diagonally extend between two pad leg sheetmetal assemblies.
The required elastic force applied is assigned to more than on an elasticity sections, so just can use the elasticity sections that coefficient of elasticity is less, thus reduces the lax of elasticity sections once again.
If use the elasticity sections that such two or more preferably diagonally extend, then preferred scheme is: these elasticity sections link into an integrated entity, and completes preferably by the common point of application of in multiple point of application and turn to.Such as, two point of applications on one of them metal assembly of pad leg plate are between the two ends of above-mentioned pair of elasticity sections, as the fixing point at these two ends, and these two point of applications are round the point of application of another metal assembly of pad leg plate.Just can use a rotatable roller or a simple axle journal here.Certainly, here also can use more than two elasticity sections.According to the design of chair type furniture, required elastic force and the width difference especially padding leg plate, be preferably designed for: have the elasticity sections that three diagonally extend at least, they are preferably connected as a single entity, be arranged in a zigzag between the point of application on two pad leg sheetmetal assemblies.
Further, if devise multiple elasticity sections between the point of application on two pad leg sheetmetal assemblies, then a part for these elasticity sections preferably integral type spring assembly, especially a part for a common elastic webbing.This reduces the cost of each part of chair type furniture, the cost especially installed.
As previously mentioned, if use a such elastic webbing, be preferably designed to realize by roller or axle journal the closed loop elastic webbing that turns to.If elastic webbing is arranged between each point of application on the same metal assembly of pad leg plate with being divided into multistage, especially an elastic webbing segmentation of furniture horizontal direction can be arranged in, just spring assembly can be extended, as long as be therefore designed with suitable transfer, the extensibility padding elasticity sections when leg plate transfers to using state from inactive state just can be reduced further.In this case, if elastic webbing is designed to closed loop, substantially ringwise, just can avoid spending sky high cost to be fixed on by the end of elastic webbing in one of them of two pad leg sheetmetal assemblies again.But directly the point of application on pad leg sheetmetal assembly being designed to turning point, elastic webbing is arranged round these turning points.Preferably each several part of this elastic webbing also designs between the point of application on same pad leg sheetmetal assembly, especially extends towards furniture horizontal direction.
Further, except in use more than except the above-mentioned advantage had during an elasticity sections, the width of pad leg plate super large also brings a special advantage.Current most of pad leg plate width are no more than 60cm, and minority chair type furniture also requires to use wider according to its purposes, such as the pad leg plate of width at least 80cm.Such as, the multiple users be sitting on a sofa can use one to pad leg plate jointly.For such pad leg plate, system conventional before this is only arranged in the spring assembly of wherein side with one, this design is very unpractical, because the mutual inclination of each pad leg sheetmetal assembly can cause problem.The design with at least two elasticity sections just evenly, prejudicially can apply active force from pad leg sheetmetal assembly both sides, especially along furniture horizontal direction, mutually the pad leg sheetmetal assembly two ends of opposition apply active force, thus can in phase, extend obliquely or shorten pad leg plate.
Further, spring assembly has two action directions, namely both can work towards the direction increasing pad leg plate, also can work towards the direction reducing pad leg plate.These two kinds diametrically opposite change in size effects are realized by foregoing controlling organization.Preferably be designed to spring assembly to work towards the direction increasing pad leg plate to pad leg sheetmetal assembly.This just means, when pad leg plate is in resting position thus when reducing, spring assembly is in tensioning state.With this as the starting point, along with pad leg plate constantly increases in the process shifted towards use location, the tensioning state of spring assembly also declines gradually.
Further, the elastic force that above-mentioned controlling organization and spring assembly produce has the opposite effect, thus in the process of pad leg plate to resting position or use location transfer, especially to resting position transfer process in by spring assembly tensioning, this controlling organization is preferably designed to control cincture, be connected on one of them metal assembly of pad leg plate, thus the elastic force making this metal assembly overcome spring assembly under the pulling force effect of this control cincture is shifted relative to another metal assembly.Control cincture is the controlling organization that a kind of shape can change arbitrarily, is designed for conduction pulling force.But a kind of stiffener also can be used to replace control cincture.By with indirectly or being directly connected of other metal assembly of chair type furniture, this controlling organization is shifted, and these metal assemblies carry out relative shift equally each other or relative to base.Like this, can there is displacement with regard to being preferably designed to landing mechanism relative to base in chair type furniture according to the invention.
In addition, another embodiment of the present invention also discloses a kind of metal assembly meeting the chair type furniture of above-mentioned design.The metal assembly of chair type furniture, comprising: a sitting face metal assembly and the first metal assembly and the second metal assembly, and they are parts of pad leg plate, can resting position and and use location between be jointly shifted,
Wherein when resting position, the first metal assembly and the second metal assembly are positioned at the below of sitting face metal assembly, and towards furniture vertical direction, when use location, the first metal assembly and the second metal assembly are positioned at before sitting face metal assembly, and towards furniture longitudinal direction, now pad leg plate can pad leg plate first metal assembly of relative shift and the second metal assembly to form and variable-length by two
Active force can be applied to the first metal assembly and the second metal assembly by some elasticity sections of spring assembly, these elasticity sections work between two point of applications, first point of application is positioned on the first metal assembly, second point of application is positioned on the second metal assembly, it is characterized in that, arrange some first point of applications and some second point of applications with mutually staggering along furniture horizontal direction thus some elasticity sections are diagonally extended; Elasticity sections is designed to elastomeric spring.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 a to 2b illustrates a chair type furniture of the present invention, and especially its metal assembly, seating portion does not draw at this.Wherein Fig. 1 a and 1b illustrates chair type furniture when pad leg plate is in resting position, and Fig. 2 a and 2b illustrates the chair type furniture that use location transferred to by pad leg plate.
First each main assembly is described according to Fig. 1 a.In fig 1 a, for the ease of understanding, the seat cushion of chair type furniture represented by dashed line.Because the working method of seat cushion for this chair type furniture cuts little ice, all will which omits in the schematic diagram therefore below.
Chair type furniture 10 is designed to a kind of couch.It has a base 12, on the ground immovably or support whole chair type furniture 10 movably when being equipped with roller.Sitting face metal assembly 14 and sitting face 14 ' thereof above this base 12.The rear side of sitting face metal assembly 14 is connected with backrest 16.In the configuration shown in Fig. 1 a, pad leg plate 18 is positioned at the below of sitting face metal assembly 14, namely in its resting position.And this pad leg device that can be used as pad leg plate 18 as the case may be also have cushion, thus when making its resting position shown in the figure, soft cushion face 18 ' downward forms pad leg soft cushion face 18 ' upward after use location transferred to by pad leg plate.
At the leading edge position of sitting face metal assembly 14, pad leg plate 18 can rotate round the rotating shaft 8 aiming at furniture horizontal direction 2.
Arrow 2,4 and 6 represents furniture horizontal direction 2 of the present invention, furniture longitudinal direction 4 and furniture vertical direction 6 respectively.
Can be found out by comparison diagram 1a and 2a, pad leg plate 18 can rotate round foregoing rotating shaft 8, thus arrives the use location substantially in level.Now, pad leg soft cushion face 18 ' is substantially concordant with sitting face 14 ', thus by padded for the leg of user, allows people feel ride comfort.
Same as can be seen from Fig. 1 a and 2a, transfer to the use location process shown in Fig. 2 a at pad leg plate 18 from the resting position shown in Fig. 1 a, the length of pad leg plate 18 also there occurs change.This length variations is to provide when the state shown in Fig. 2 a on the one hand enough large surface to support the leg of user, be on the other hand neat in order to pad leg plate 18 is put when the state shown in Fig. 1 a, thus especially rotate carrying out in the process of the resting position transfer shown in Fig. 1 a from the use location shown in Fig. 2 a.When padding leg plate 18 and being in outwardly directed state shown in Fig. 2 a, pad leg plate 18 can not rotate towards the direction of resting position, otherwise pad leg plate 18 can collide with the base 12 of ground or this furniture.
Can find out in Fig. 1 b and 2b of observation base chair form furniture especially from below, pad leg plate 18 comprises two can the metal assembly of relative movement, i.e. the first metal assembly 30 and the second metal assembly 40.First metal assembly 30 directly can rotate round rotating shaft 8.Although second metal assembly 40 in outside, also along with the first metal assembly 30 rotates together, can also carry out Linear-moving relative to the first metal assembly 30.For this reason, the first metal assembly 30 and the second metal assembly 40 are designed with the linear guides 28 do not drawn in detail in figure.Because the first metal assembly 30 and the second metal assembly 40 can relative shifts by this way, just achieve the foregoing length variations of pad leg plate 18.
In order to control this length variations, devise a flexible control cincture 26, one end is connected on the pad leg sheetmetal assembly 40 in outside, the other end is connected with sitting face metal assembly 14, therefore this control cincture 26 length when moving to position shown in Fig. 2 a, that relatively decline from the position shown in Fig. 1 a can freely change, and so just makes pad leg sheetmetal assembly 40 can be protruding.This control cincture 26 does not draw in fig 1 and 2, only draws a part in figure 2b.
Control cincture 26 is used as the controlling organization of control pad leg plate 18 length variations.The pulling force applied by this control cincture 26 plays the effect reduced by pad leg plate 18, and action direction is completely contrary with the elastic force direction of spring assembly 50.Spring assembly 50 works between pad leg plate first metal assembly 30 and the second metal assembly 40, the connected mode of it and the first metal assembly 30 and the second metal assembly 40 is, make pad leg plate 18 protruding under the effect of elastic force, namely pad leg plate 18 and shift to use location.
In order to explain that spring assembly 50 refers to Fig. 3 a and 3b in detail, wherein Fig. 3 a is pad leg plate 18, Fig. 3 b being in resting position is the pad leg plate 18 being in use location.The architectural feature of the first metal assembly 30 and the second metal assembly 40 can be found out from Fig. 3 a.Pad leg plate second metal assembly 40 has the tower structure of ring seal, mainly comprises two second cross beams 42.Pad leg plate first metal assembly 30 takes the shape of the letter U, and has a first crossbeam 32 equally.On one of them second cross beam 42 of the second metal assembly 40, be designed with second deflecting roller 43.On the first crossbeam 32 of the first metal assembly 30, devise the first deflecting roller 33 that two are positioned at outside.These three deflecting rollers are wound up by a common elastic webbing 53, and this elastic webbing 53 surrounds a huge annular, preferably circular.By the arrangement that the elastic webbing 53 round deflecting roller is such, when padding leg plate and being in the inactive state shown in Fig. 3 a, this elastic webbing 53 defines a triangle.Under this inactive state, elastic webbing 53 is subject to the effect of tension, that is, no matter two elasticity sections 53a between the first deflecting roller 33 being used as the point of application and the second deflecting roller 43, or that stretch along furniture horizontal direction 2, between two the first deflecting rollers 33 of the first metal assembly 30 elasticity sections 53b, all effects of under tension.
If pad leg plate 18 is positioned in its resting position, then control cincture 26 forces spring assembly 50 to be in this tensioning state, as shown in Figure 3 a.Like this, pad leg plate 18 and just remain on its compact condition.
Now, if to transfer in the process of comfortable position sitting face metal assembly 14 at chair type furniture 10 relative to base to backward shift, and pad leg plate 18 towards its use location to inner rotary, so just constantly unclamped by control cincture 26, spring assembly 50 just can make pad leg plate 18 area increase under elastic force effect.Now elastic webbing 53 relaxes gradually by straining, until it reaches maximum relaxed state when pad leg plate is in the protruding state shown in Fig. 3 b, now the second metal assembly 40 reaches at utmost relative to the displacement of the first metal assembly 30.
Two elasticity sections 53a diagonally extend and elasticity sections 53b walks around deflecting roller 33 and substantially plays balanced action, and according to these two facts, the extensibility of elastic webbing 53 is merely add about 10% than during state shown in Fig. 3 b during state shown in Fig. 3 a.Without the need to harmful relexation, just can permanently realize such extensibility with an elastic webbing.
Fig. 4 to 7 illustrates a series of alternate design scheme.
In the design shown in Fig. 4, employ a kind of metal coil spring 54 of routine, on first point of application 34 that its two ends are separately fixed at pad leg plate first metal assembly 30 and the second metal assembly 40 and second point of application 44.Here do not adopt shown in Fig. 3 a and 3b, realized the design that turns to by deflecting roller.Even if use foregoing elastic webbing advantageously, diagonally arrange that a helical spring also has very large advantage.For shown in Fig. 4, be under extended state helical spring for, because it is diagonally arranged, extended state when extensibility only increases than pad leg plate adds 15-20%.
In a deformation design scheme that here do not draw, Fig. 4, the metal coil spring 54 here by two ends be separately fixed at an elastic webbing on the first metal assembly 30 and the second metal assembly 40 replace.
In the design shown in Fig. 5, employ an elastic webbing 55 equally, but with the elastic webbing 53 shown in Fig. 3 a and 3b unlike, it is fixed on the point of application 35 position of pad leg plate first metal assembly 30.Only on pad leg plate second metal assembly 40, second deflecting roller 45 is installed, the same with shown in Fig. 3 a.But this second deflecting roller 45 just plays the effect of being convenient to install.In a flexible program of design shown in Fig. 5, replace an elastic webbing 55 turned to by the second deflecting roller 45, can use two independently elastic driving bands, they are connected with the second metal assembly 40 respectively at the second deflecting roller 45 position.
In the design that Fig. 6 shows, replace two sections of elasticity sections that stretch between pad leg plate first metal assembly 30 and the second metal assembly 40, spring assembly 50, devise 3 sections of such elasticity sections 56a, one end of these elasticity sections is connected securely with pad leg plate first metal assembly 30, and the other end is connected securely with the second metal assembly 40.Increase the quantity of the elasticity sections that spring assembly 50 stretches between two pad leg sheetmetal assemblies, this spring assembly just can be allowed to be equipped with the less elasticity sections of coefficient of elasticity, these elasticity sections concur, and just can replace the higher elastic driving band of coefficient of elasticity.
Fig. 7 illustrates a flexible program of design shown in Fig. 3 a, wherein replaces a deflecting roller 43 in the side of pad leg plate second metal assembly 40, devises two the second deflecting rollers 47.Replace two deflecting rollers 33 in the side of the first metal assembly 30, devise three the first deflecting rollers 37.With similar shown in Fig. 6, the elasticity sections 57 of spring assembly 50 redesigns zig zag structure.
Fig. 8 illustrates an alternative embodiment of the invention.Here the pad leg plate 18 shown in remains static.The special character of this design is the width padding leg plate 18.At furniture in a lateral direction, the width of this pad leg plate reaches about 80cm.The spring assembly that the size of pad leg plate 18 is changed is designed to elastic driving band 58 again, form a quadrangle haply here, namely walk around two the second deflecting rollers 48 on the second metal assembly 40 and two the first deflecting rollers 38 on the first metal assembly 30.The elasticity sections 58a stretched between the first metal assembly 30 and the second metal assembly 40 redesigns into diagonally, but this not necessarily.As an alternative, these two elasticity sections oppositely can stretch mutually towards the relative shift direction of the first metal assembly 30 and the second metal assembly 40.These two elasticity sections 58a preferably from location, outside, thus make it be arranged in the side of corresponding linear guides 28, and the effect of the latter makes pad leg plate first metal assembly 30 and the second metal assembly 40 can relative movement.This relative movement is so just made not have the trend of inclination.Therefore, although the width of pad leg plate 18 is large especially, also can guarantees that it reliably runs, especially can lean against between resting position and use location and switch.The first deflecting roller 38 on the first metal assembly 30 and the second deflecting roller 48 on the second metal assembly 40 are apart from very large, therefore elasticity sections 58b and 58c of balanced action is played in-between in addition, they, when the characteristic driving-belt using extensibility less, switch between the use location that pad leg plate can be made not draw in the drawings and the resting position shown in Fig. 8.
