But the invention provides one group of adjustable height bracket, preferably be used with electronic installation with horizontal shift.For diversification and different consumer demand, thereby design the present invention and have and increase to adjust the support for the treatment of stilt displacement stability in response to product.The electronic installation of this place speech is preferably flat-panel screens such as comprising liquid crystal display screen or plasma picture element screen, as shown in Figure 1.Yet in other different embodiment, also can treat to use in the stilt as monitor, light fixture, Medical Devices, machine tool and other.Below promptly further specify the appended graphic and step of preferred embodiment of the present invention:
As shown in Figure 1, adjustable height bracket of the present invention comprises pedestal 120, connecting portion 130, at least one first slide rail set 200, at least one second slide rail set 300 and at least one support 500.Connecting portion 130 is arranged at pedestal 120 tops, for connecting the usefulness for the treatment of stilt 100.Yet in other different embodiment, connecting portion 130 is located in also can be directly and is treated in the stilt 100.First slide rail set, 200 preferable being arranged on the connecting portion 130, and first slide rail set 200 has first slide rail 210; Yet in different embodiment, first slide rail set 200 also can directly be arranged at and treat on the stilt 100.The stilt 100 for the treatment of described herein comprises electronic installation, monitor, light fixture, Medical Devices, machine tool or other need be adjusted on the device of height.
In embodiment as shown in Figure 1, first slide rail set 200 preferably comprises first slide rail 210 of paired setting, and is arranged at the left and right sides of connecting portion 130 bottoms respectively.Second slide rail set 300 is arranged on the pedestal 120, and second slide rail set 300 has second slide rail 310.In embodiment as shown in Figure 1, second slide rail set 300 preferably comprises second slide rail 310 of paired setting, and is arranged at the left and right sides of pedestal 120 upper limbs respectively.Yet in different embodiment, the first single slide rail 210 and corresponding second slide rail 310 can only be set also.The two ends of support 500 are to be connected in first slide rail set 200 and second slide rail set 300 movably, and can slide along first slide rail 210 and second slide rail 310.In embodiment as shown in Figure 1, preferably comprise one and form support 500, the relative horizontal shift of each support 500 will make and treat stilt 100 its relative heights of adjustment.Yet in the embodiment of Fig. 2 a, single support 500 can be set also.Especially bad, support 500 more than two also can be set among the embodiment shown in Fig. 2 b.Wherein many support 500 right and wrong setting in the same plane.
In addition, one of them is that the mode of pressing from both sides an angle with surface level is provided with at least for first slide rail set 200 and second slide rail set 300.In embodiment as shown in Figure 1, each first slide rail 210 and each second slide rail 310 are preferably in the same plane and be each other and be symmetrical arranged.Furthermore, each first slide rail 210 and each second slide rail 310 all press from both sides an angle with surface level, make the support 500 can be along moving on the formed imaginary inclined-plane of this angle.By this design, when support 500 along first slide rail 210 and second slide rail, 310 generation levels during to displacement, support 500 and treat that stilt 100 promptly simultaneously produces corresponding displacement in vertical direction, and then reach and adjust the purpose for the treatment of stilt 100 height.
In embodiment as shown in Figure 1, cause first slide rail 210 and second slide rail 310 all form imaginary inclined-plane, in other words, treat that stilt 100 adjustable height strokes are relatively large, and the depth of section of pedestal 120 and the required size (length) of slide rail can design relatively less.Yet in the embodiment shown in Fig. 2 a, also can one of them be arranged to get final product at angle with surface level with first slide rail set 200 or second slide rail set 300.In other words, each first slide rail 210 and each second slide rail 310 are in the same plane, correspond to each other but are not to be symmetrical arranged.That is to say that one of them slide rail and surface level are provided with at angle, another slide rail then becomes the surface level setting.No matter yet be which slide rail set and surface level are provided with at angle, treat that stilt 100 only can utilize an imaginary inclined-plane adjustment height.Therefore, treat that 100 height that can adjust of stilt are less relatively, treat that the size (length) of the cross-sectional length of the cross-sectional length of stilt 100 or pedestal 120 and slide rail is then relatively large.
Below further specify the annexation of first slide rail set 200 and support 500, shown in Fig. 3 a and 3b.First slide rail set 200 comprises first slide rail 210, slide block 230 and is arranged at the wear-resistant block 240 of slide block 230 2 sides in pairs.In the embodiment shown in Fig. 3 a and 3b, slide block 230 1 ends preferably are fixed in an end of support 500, and 240 of wear-resistant blocks are arranged at respectively on the other end of slide block 230, and conflict with the inwall of first slide rail 210.Yet in other different embodiment, wear-resistant block 240 also can with slide block 230 integrally formed settings.In other words, wear-resistant block 240 can be selected the material similar with slide block 230 for use.In the present embodiment, the material of wear-resistant block 240 system comprises plastic cement, rubber, synthetic resin or other wear-resisting material.Base this, support 500 can move in the inwall of first slide rail 210 by wear-resistant block 240 set on the slide block 230.
Shown in Fig. 4 a and Fig. 4 b, first slide rail, 210 inwalls more comprise flexible member 220 are set, for replying the initial position for the treatment of stilt (figure does not illustrate).Please also refer to shown in Fig. 5 a, flexible member 220 two ends connect first annular clip-ring 222 and second annular clip-ring 224 respectively.Further has hole 226 in the middle of first annular clip-ring 222 and second annular clip-ring 224.In the embodiment shown in Fig. 4 a, Fig. 4 b and Fig. 5 a, slide block 230 1 sides are preferably to be provided with to be preferably on slide block trip 232, the first slide rails 210 1 end side surface and are provided with slide rail trip 212.Slide block trip 232 and slide rail trip 212 supply first annular clip-ring 222 and second annular clip-ring, 224 snappings of elasticity element 220 respectively.In addition, in the present embodiment, flexible member 220 is preferably volute spring.Yet for example among the embodiment shown in Fig. 5 b, flexible member 220 also can be provided with fixed force spring.
When if fixed force spring 220 is set, shown in Fig. 5 b, the spring ora terminalis 234 that is about to spring axostylus axostyle 228 and tool hole 226 is arranged at respectively on slide block trip 232 and the slide rail trip 212.When slide block 230 when slide rail moves, spring axostylus axostyle 228 promptly produces displacements with respect to spring ora terminalis 234.Because the elastic force of each length of fixed force spring 220 equates, so entire system all remains unchanged for the anchorage force for the treatment of stilt.
And for example shown in Fig. 6 a and Fig. 6 b, the solid and the exploded view that are connected with second slide rail set for support.Second slide rail set 300 comprises second slide rail 310, slide block 330 and is arranged at the wear-resistant block 340 of slide block 330 2 sides in pairs.Slide block 330 1 ends are fixed in an end of support 500, and the other end is conflicted by the inwall of the wear-resistant block 340 and second slide rail 310.Its mode of operation and material are same as above, do not repeat them here.
When the high and low position of stilt was treated in adjustment, support 500 two ends produced friction force by wear-resistant block 240,340 in the inwall of first slide rail 210 and second slide rail 310, treated that with prevention stilt moves downward or upward.Flexible member 220 screen resiliences by being arranged at each first slide rail 210 make and treat that stilt has the pulling force up or down of replying the original position again.Therefore before carrying out height control and after carrying out height control, treat that the weight of stilt, the elastic force of flexible member 220 and the friction force that wear-resistant block 240,340 produces reach balance, and then reach the purpose of location.And in height adjustment process, with the position of traversing carriage 500, and then change the height treat stilt 100 along first slide rail 210 and second slide rail 310 by this balance of outside destroy.When with fixed force spring during as flexible member 220, this system balancing can only consider to treat the balance between stilt 100 and flexible member 220 elastic forces.Yet when adopting non-fixed force spring such as volute spring as flexible member 220, the friction force that wear-resistant block 240,340 produces promptly need be adjusted, with the force variation that cooperates flexible member 220 to produce because of stretching.
Another embodiment when Figure 7 shows that with volute spring as flexible member 220.Because of helical spring elastic force can increase along with the displacement that stretches, therefore can opposite force be set additionally comes balance.As shown in Figure 7, set up bonnet 150 (shown in dotted line) at the rear wall for the treatment of stilt 100.In embodiment as shown in Figure 7, the quantity of the bonnet 150 preferably quantity with support 500 is corresponding; Yet in different embodiment, single bonnet 150 also can only be set for cooperating with a plurality of supports 500.The position that each bonnet 150 is provided with covers 500 on support and can move the imaginary area of formation.Shown in Fig. 8 a and 8b, the inwall of bonnet 150 further is provided with friction cover plate 152, and support 500 friction cover plate 152 relatively is provided with friction block 510.Friction cover plate 152 is conflicted mutually with friction block 510, to produce friction force.In the embodiment shown in Fig. 8 a and 8b, the both sides of bonnet 150 preferably are formed with stop part 154, for stopping and limit bracket 500 paramount reaching to low extreme displacement.Yet similar to friction block 510 materials, that is comprise plastic cement, rubber, synthetic resin or other wear-resisting material to the wear-resistant block material at this friction cover plate 152 of saying.
Certainly, be located at the friction cover plate 152 of bonnet 150 and the form that friction block 510 also can be designed to independent component in the present embodiment, must do not integrate and be arranged on the bonnet 150.
When treating that stilt 100 is positioned to the high position, shown in Fig. 8 a, flexible member 220 is minimum extended state at first slide rail 210, that is the friction force of friction cover plate 152 and 510 generations of friction block is located and treated stilt 100 more than or equal to the elastic force of flexible member 220.The user only need overcome the maximum static friction force of 510 of friction cover plate 152 and friction blocks, and promptly movable supporting frame 500 is to turn down the position for the treatment of stilt 100.In the embodiment shown in Fig. 8 b, when treating that stilt 100 is positioned to lower position, flexible member 220 is the longest extended state, at this moment the screen resilience maximum of flexible member 220.The conflict area maximum of 152 formation of friction cover plate of the friction block 510 of its medium-height trestle 500 and bonnet 150, the friction force of generation are also maximum.In the present embodiment, friction cover plate 152 and 510 areas of being conflicted of friction block, that is the friction force of friction cover plate 152 and 510 generations of friction block preferably equates with the screen resilience of flexible member 220 and can repeal by implication, thereby can locate the position for the treatment of stilt 100.
This shows that when the tensile elongation of flexible member 220 is long more, friction cover plate 152 and 510 areas of being conflicted of friction block are big more; Short more when the tensile elongation of flexible member 220, friction cover plate 152 and 510 areas of being conflicted of friction block are more little.Can locate arbitrary height and position for the treatment of stilt 100 therefrom.In other words, will treat stilt 100 from being adjusted to the high position to lower position when desire, the maximum static friction force that only need overcome 510 of friction cover plate 152 and friction blocks gets final product.
Shown in Fig. 9 a and Fig. 9 b, for being applied to the enforcement illustration of electronic installation.The electronic installation 100 of this place speech preferably refers to the plane display screens.Yet the plane display screens more comprises liquid crystal display screen or plasma picture element screen.In the embodiment shown in Fig. 9 a and Fig. 9 b, adjustable height bracket preferably is arranged on the both sides, electronics 110 bottom.Wherein electronics 110 also is provided with some electrical equipment with hole (figure does not illustrate), for the usefulness of transmission line or power lead grafting.When the flexible member 220 of electronic installation 100 uses volute spring, then need be oppositely arranged extra opposite force and come balance, shown in Fig. 9 b.In other words, need to be provided with as: the friction force of the friction cover plate of bonnet 150, bonnet inwall and the support friction block mechanism generations such as (figure do not illustrate) relative with the friction cover plate is offseted.Detail operations mode and dependency structure are same as above, do not repeat them here.
