Description

Lifting/lowering storage device

The present invention relates to a kind of lifting/lowering storage device of lifting storage rack, this storage rack is arranged in the shell that resembles eminence the hanging cupboard.

Past resembles the hanging cupboard eminence shelf is installed, and deposits some things above, but because too high, deposit or get thing and all compare difficult.

Therefore, present inventors have considered the lifting/lowering storage device shown in Figure 59～Figure 64 in finishing process of the present invention.This lifting/lowering storage device is to resemble eminence the hanging cupboard, shell 2 is installed, be provided with in the shell front freely rotate 3, the hinge 4 of door 3 is installed in the both sides up and down of the side 2a of shell 2 respectively, in this shell 2,, storage rack 6 is freely moved to the front lower place by connecting rod mechanism 5.Described connecting rod mechanism 5 constitutes parallel rod by front rod 7 and rear linking rod 8, and an end of these two connecting rods is separately fixed in the shell 2 side rotating shafts, and the other end is fixed in the side rotating shaft of storage rack 6.By the connecting rod mechanism 5 that this parallel rod constitutes, can move storage rack 6 its front lower place to or rise to the top being recovered in the shell 2 from shell 2.In addition, the axle of the lower end 7b of front rod 7 has been installed the coil spring 11 (Figure 59) that plays shock damping action from shell 2 when leave behind in front lower places on 9, and this coil spring 11 is fixed on 17 li of shaft seats that are installed in shell 2 side 2a.The shock absorber 12 (Figure 62) that the axle of rear linking rod 8 lower end 8b go up to be installed when shell 2 descends toward front lower places shock damping action, is made up of oil brffer etc.

But during the connecting rod mechanism 5 that the parallel rod shown in employing Figure 59 constitutes, coil spring of installing on the axle 9 of front rod 7 11 and shaft seat 17 grades that this spring is installed are fixed on the side 2a of shell 2 near on the position of leading edge, go up the door 3 that freely rotates so be fixed on shell 2 side 2a, the fixed part of downside hinge 4 is affected.Therefore must up carry the anchor fitting of door 3 downside hinges 4 than the position of shaft seat 17, the installation degree of freedom of hinge 4 diminishes, and if the distance D between upside hinge 4 and the downside hinge 4 diminish the installation bad stability of door 3.Especially for shown in Figure 59, in the form that shell 2 bottoms installation embedding illumination instrument 13 becomes one, the height of the rotating shaft 9 of front rod 7 lower end 7b also will improve the height of lighting fixture 13, thereby the installation site of downside hinge 4 also will be put on, its result, that lighting fixture 13 is installed in shell 2 bottoms and lighting fixture is not installed, the height and position of door 3 downside hinges 4 differs greatly, this not only can not accomplish installation site unitized of hinge 4, and door 3 kind increases, and productivity is poor as a result for it.

In addition, when adopting the connecting rod mechanism 5 of above-mentioned parallel rod formation, the problem below occurring in the assembling process.Each upper end 7a, 8a of front rod 7 shown in Figure 62 and rear linking rod 8 install rotating shaft plate 23, then this rotating shaft plate 23 are fixed on the side of storage rack 6.At this moment, front rod 7 and rear linking rod 8 are put in the shell 2, support storage rack 6 with hand, the rotating shaft plate of installing on front rod 7 and the rear linking rod 8 23, are fixed on the side of storage rack 6 with screw.Therefore, when supporting storage rack 6 and pack shell 2 into with screw fixedly during storage rack 6 with hand, if storage rack 6 is run into the side 2a inner face of shell 2, be easy to generate scar, particularly shell 2 is with resin forming, intensity also a little less than, if the inner face of the side 2a of shell 2 has scar, after the pulling of front lower place, can see scar from shell 2, influence the outward appearance of shell 2 to storage rack 6.

In order to address the above problem, present inventors have found out as shown in Figure 65, on the 2a of the side of shell 2, in the time of with screw 53 fixed installation substrate 25, be installed in shock absorbers 12 such as the coil spring 11 of rear linking rod 8 and oil brffer, cover with public case 29, and be fixed on the method for described installation base plate 25 with mechanism's plate 24 that this case 29 fuses.So, install installation base plate 25 in advance, when 2 li on shell assembling storage rack 6, can prevent that locking mechanism plate 24 runs into the inner face of shell 2 side 2a and produce scar.But for installation base plate 25 and mechanism's plate 24 usefulness screws are fixed on shell 2, when removing the burr around the hole of installation base plate 25 and mechanism's plate 24, according to the construction state, between mechanism's plate 24 and the installation base plate 25, because the bore edges (protuberance) 26 of burring, can produce clearance G (for example 2mm), this not only influences attractive in appearance, and insect enters this clearance G or lays eggs in the inside sometimes, and in when construction, during the fixed orifice 26 to process respectively on aligning guide plate 24 and the installation base plate 25, mechanism's plate 24 misplaces easily with respect to adapter plate 24, be not easy to aim at, thereby, can spend a lot of time with the fixing operation of screw.

Present inventors have considered the scheme shown in Figure 66 for the lifting action of holding rack 6 can carry out sleekly.One end of oil hydraulic cylinder 101 is supported on the position than the axle 10 lower close bottom 8b of rear linking rod 8, and the front end 103a of the piston rod 103 of pulling out from the other end of oil hydraulic cylinder 101 is fixed on shell side, utilizes the descending speed of the drag control storage rack 6 that oil hydraulic cylinder 101 produces.Like this, storage rack toward the front lower place when leaving behind, can additional resistance, even under the big situation of the load of storage rack 6, storage rack 6 can not fall very soon, has improved safety.But following problem occurred: rear linking rod 8 is the center with axle 10, arrow H direction toward Figure 66 is rotated, the piston rod 103 of oil hydraulic cylinder 101 on the direction shown in the arrow J when flexible, on piston rod, produce the resistance equidirectional that produces with oil hydraulic cylinder 101 (axially power a) and with the meet at right angles power of direction (meeting at right angles) of resistance that oil hydraulic cylinder 101 produces with axial a.Flexible with the situation lower piston rod 103 that adds power on the rectangular direction b of axial a, so, produce between the piston rod 103 of oil hydraulic cylinder 101 and the oil hydraulic cylinder end cap and ask the crack, from this gap, as shown by arrow C can leakage of oil, flow to the outside of oil hydraulic cylinder 101, only can not solve the problem of leakage of oil fully by oil cap 77, thereby oil drops in the shell, not only influences attractive in appearancely, and brings discomfort to the user.

The lower end 7b of described front rod 7 goes up on the fixing axle 9, and mechanisms such as coil spring are not set as before, and countershaft seat 17 free states support.The support portion 9a of the lower end 7b of this front rod 7, as shown in Figure 3, be positioned on the position of rear end 4a after more of fixed part of door 3 downside hinge 4, because after the support portion 9a of the lower end 7b of front rod 7 relatively leans on, can avoid the installation site of door 3 downside hinge 4 to uprise or when lighting fixture is installed in the bottom of shell 2, raise the problems such as installation site of the downside hinge 4 of door 3.

On axle 10 fixing on the 8b of the lower end of rear linking rod 8, as shown in Figure 2, be provided with storage rack 6 and rotate when being left behind from shell 2 past front lower places, play 2 coil springs 11,15 of shock damping action.Here, the axle 10 usefulness snap rings of rear linking rod 8 are fixed, and at the front end of axle 10 coil spring 11 and 15 are installed.2 coil springs 11 and 15 are arranged side by side on the length direction (with the perpendicular direction of Fig. 2 paper) of axle 10 of rear linking rod 8, when storage rack 6 when leave behind in past front lower place from shell 2 in, all add spring force, play shock damping action.2 coil springs 11 and 15 are arranged on 17 li of shaft seats, and this shaft seat 17 is arranged between the side 2a and connecting rod mechanism 5 of shell 2, and this shaft seat is provided with the bearing portion 18 and 19 (Fig. 5) of the axle 9,10 of each bottom 7b, the 8b that support front rod 7 and rear linking rod 8 respectively for 17 li.In example shown in Figure 2, an end of a coil spring 11 is fixed on the spring fixed part 28 in the shaft seat 17, and the other end applies spring force all the time to the axle 10 of rear linking rod 8.One end of another coil spring 15 is fixed on the groove 30 that axle 10 the front end of rear linking rod 8 is left, and the other end is being supported by spring force adjusting device 14.14 li of this spring force adjusting devices, there is the other end of another coil spring 15 to be in the operating mechanism 16 that stationary state can switch on free state or the shell 2 for shell 2, the rocking arm 32 of the buckle 31 that drives by operating mechanism 16, the combining mechanism 33 of the combination freely of on the hook portion 31 of rocking arm 32, linking up with or break off relations.

In the described operating mechanism 16, bonded assembly push rod 35 on the operating knob (action button) 34 of the outer setting of shaft seat 17 is arranged, and can freely slide in the hole that this push rod 35 injects shaft seat 17, and owing to the retracing spring 36 of suit on the push rod 35, operating knob 34 applies spring force towards the place ahead all the time simultaneously.In shaft seat 17 inside, be provided with respectively because the rocking arm 32 of push rod 35 swing and can freely link up with or the hook 37 of the combination of breaking off relations to the hook portion 31 of rocking arm.Among the figure 80 is the installation position of hook.Rocking arm 32 is that the center can be rotated freely with the turning cylinder 38 that is installed in shaft seat 17, simultaneously because the spring force of the torsion spring 39 that is provided with on the turning cylinder 38, and the lower end 32b of rocking arm 32, the front end towards push rod 35 applies spring force all the time.Press the push rod 35 of operating knob 34, the lower end 32b of rocking arm 32 forwards the direction near hook portion 37 to, and the hook portion 31 that the back side of the lower end 32b of rocking arm 32 is provided with is freely linked up with hook portion 37 or broken off relations.

Described hook portion 37 as shown in Figure 8,40 li of cylindrical housings, has the slide bar 41 that can be free to slide, and has thin-walled shape to withhold 42 at its front end and forms one.Slide bar 41, stretches out towards outstanding outward direction at the fwd peristome 44 of cylindrical housing 40 all the time owing to the compression springs 43 that are provided with in the cylindrical housing 40.Slide bar 41 and withhold portion 42 and reverse U shape hook 37 is integral with resin molding method, and under state of nature, shown in Fig. 8 (a), the upper wall 37a of hook 37 is to the facial formation bevelled of going up of slide bar 41 state.When pressing operating knob 34, when the front end of catch bar 35 promotes the lower end 32b of rocking arm 32 toward the direction of hook shown in the 37 side arrow d; the hook portion 31 of rocking arm 32 enters the direction shown in the arrow e of Fig. 8 (a); enter roughly 37 li of the hook portion of state down; meet rear surface 37b, the result is shown in long and short dash line m among Fig. 8 (a); withhold 42 and flattened, the last facial almost parallel of the upper wall 37a of hook portion 37 and slide bar 41.At this moment, [direction of n among Fig. 8 (b)] rearward moved in slide bar 41 beginnings, and by torque spring 45, slide bar 41 rests on rear position [state of Fig. 8 (b)] or removes the stop state, and the state [state of Fig. 8 (a)] of slide bar 41 being shifted onto the place ahead can switch.Constitute combining mechanism 33 by these torque springs 45, hook 37 and slide bar 41 etc.

The side of the slide bar 41 in the described cylindrical housing 40 is provided with heart cam groove 47, in the moving body 46 insertion heart cam grooves 47 that the tip of the torque spring 45 that the rear wall of cylindrical housing 40 is installed is fixed.Heart cam groove 47 stops groove 48 and rear side guide groove 50a and front side by rear side and stops that groove 49 and front side guide groove 50 link up, since guide groove 50,50a difference, the both sides shape difference of heart cam groove 47.Front and back guide groove 50,50a make the moving body 46 of torque spring 45 interior mobile to a direction (for example clockwise direction) along heart cam groove 47.As Fig. 8 (a), moving body 46 stops the stop state (position that slide bar 41 moves) of groove 48 forward from rear side, promote 41 moving bodys 46 of slide bar from the place ahead in described hook portion 31 and slide in the guide groove 50a, the direction of arrow to Fig. 8 (b) moves to front side stop groove 49 by guide groove 50a again.At this moment owing to the elastic force of compression spring 43, moving body 46 rests on the front side and stops on the groove 49, and slide bar 41 remains on the outstanding position, the place ahead.Then, during pressurized, moving body 46 enters in the front side guide groove 50 shown in Fig. 8 (c) slide bar 41 again, moves to rear side from this guide groove 50 again and stops the position that groove 48 is got back to Fig. 8 (a).At this moment owing to the spring force of compression spring 43, moving body 46 rests on rear side and stops groove 48 maintenance stop states, the position that slide bar 41 maintenances retreat.When slide bar 41 rested on the rear position here, as mentioned above, facial 41a keeping parallelism on hook 37 and the slide bar 41 was so to linking up with 37, the lower end 32b of rocking arm 32 goes up the hook portion 31 that is provided with and is in bonding state; And when being in the stop state on the forwards outstanding position of slide bar 41, as mentioned above, the last facial 41a of 37 pairs of slide bars 41 of hook is bevelleds, so link up with 37 and hook portion 31 releasing bonding states.

In addition, on the 32a of the upper end of rocking arm 32, as shown in Figure 1, have a face be inclined-plane 51a in conjunction with protuberance 51, this in conjunction with protuberance 51 can be freely in conjunction with or break away from the く oxbow portion 52 that the other end of coil spring 11 is bent to form.When withstanding く oxbow portion 52 (the lower end hook portion 31 of rocking arm 32 is anchored to when linking up with 37) in conjunction with protuberance 51, inclined-plane 51a withstands く oxbow portion 52 toward the top, enter in the く oxbow portion 52 in conjunction with protuberance 51, thereby 2 coil springs 11 and 15 spring forces work simultaneously.When the direction of leaving from く oxbow portion 52 in conjunction with protuberance 51 is rotated (when hook portion 31 and hook 31 break off relations), because in conjunction with protuberance 51 ｀, く oxbow portion 52 pushes open toward the top, break away from く oxbow portion 52 in conjunction with protuberance 51, thereby, coil spring 15 state that affranchises has only the spring force of a coil spring 11 to work.

On the lower end 8b of described rear linking rod 8 extension 8c is arranged.The side 2a of this extension 8c and described shell 2 goes up between the installation base plate of installing 25, is provided with storage rack 6 rotates shock damping action when pulling down from shell 2 past front lower places another shock absorber 12.This shock absorber 12 for example is made of oil brffer 12b.The end of oil brffer 12b rotates the extension 8c that is fixed on rear linking rod 8 freely, and the other end of oil brffer 12b by bearing, rotates and is fixed on installation base plate 25 freely.The other end of oil brffer 12b and bearing become one on sheet metal.Oil brffer 12b is storage rack 6 shock damping action when shell 2 is left behind toward front lower places, when applying spring force, when the Heavy Weight of storage rack 6, alleviates the burden of coil spring 11, can play preventing that coil spring 11 from reducing the effect in life-spans.Certainly, shock absorber 12 is not limited to the form of oil brffer 12b, also can adopt gas spring etc.

But, the lower end 7b of front rod 7 goes up fixing axle 9 and is supporting with free state, not not as before, on the axle 9 of the lower end 7b of front rod 7 coil spring 11 is installed, the shaft seat 17 of putting into coil spring 11 does not need to be fixed on the position of close front end of the side 2a of shell 2, thereby on shell 2 side 2a, rotate the installation portion 5 of the downside hinge 4 of the door of installing freely 3, can be arranged in the place ahead of shaft seat 17.Therefore, the downside hinge 4 of door 3 can be arranged in the position of the upward close lower end of side 2a of shell 2, needn't strengthen the size up and down of shell 2, also can increase the distance D between upside hinge and the downside hinge 4, the installation stability of door 3 is improved, and needn't change the installation site of downside hinge 4, can unify the kind of door 3.

Shown in Figure 10 (a), under the situation of shell 2 bottoms assembling embedding illumination instrument 13, the height of the axle 9 of the lower end 7b of front rod 7 will improve the part of the height of lighting fixture 13, but, as mentioned above, mechanisms such as coil spring are not installed on the axle 9 of front rod 7, are in free state, can reduce the setting height(from bottom) of downside hinge 4.Just the bottom of shell 2 assembling embedding illumination instrument 13 and as Fig. 1 O (b) shown in, do not assemble lighting fixture 13, can unify a kind of 3.

On the extension 8c of rear linking rod 8, connect oil brffer 12b, so oil brffer 12b can not run into fixing coil spring 11 on the axle 10 of lower end 8b of rear linking rod 8, therefore, to the lower end 8b of rear linking rod 8, coil spring and oil brffer 12b can be installed simultaneously.

Described front rod 7 and rear linking rod 8 all bend to the へ font to same direction respectively, and storage rack 6 is moved to toward front lower places when minimum from shell 2, owing to bend to the part of へ font, can guarantee required gap E between front rod 7 and rear linking rod 8.Like this, when leaving behind storage rack 6, between front rod 7 and rear linking rod 8, even reached into because of carelessness, can clip finger yet, guarantee the storage rack 6 of leaving behind under the prerequisite of the safety used.Compare with the be in line situation of shape of front rod 7 and rear linking rod 8, because the へ oxbow portion of connecting rod, the maximum lowering position of front rod 7 and rear linking rod 8 can be lower, deposits on the storage rack 6 or to get thing easier.

In addition, on the lateral surface of the shaft seat 17 that coil spring 11 is installed, bearing portion 18,19 is set, it is to support the axle 9 of each bottom 7b, 8b of front rod 7 and rear linking rod 8 and 1O, so can be support section 9a, the 10a of the bearing portion 18,19 of shaft seat 17 near front rods 7 and rear linking rod 8.And if the distance between the bearing portion 18,19, axle 9,10 is added big moment, bring obstacle for the rotational action of storage rack 6.For fear of this phenomenon, in this enforcement state, the lateral surface of the shaft seat 17 of installation coil spring 11 is used as pedestal and is used, the bearing portion 118,19 of the axle 9,10 that supports front rod 7 and rear linking rod 8 is set on this pedestal, like this axle 9, the 1O of bearing portion 18,19 close connecting rods 7,8 are applied big moment, the lifting action of storage rack 6 can carry out smoothly.

If during storage rack 6 in light weight,, can alleviate spring force by spring force adjusting device 14.At first press operating knob 34, push rod 35 advances inward, the hook portion 31 that is arranged on the 32b of rocking arm 32 lower ends is inserted in the downward opening hook 37, the rear wall 37b that promotes hook 37 is pressed to the rear, hook 37 becomes the deformation state shown in long and short dash line m among Fig. 8 (a), slide bar 41 rearward d moves, and rests on the going-back position by torque spring 45.At this moment; the upper end 32a of rocking arm 32 breaks away from conjunction with the く oxbow portion 52 of protuberance 51 from coil spring 15; coil spring 15 becomes free state; have only the spring force of coil spring 11 to act on storage rack 6; can alleviate spring force, even also easily storage rack 6 is drawn into nadir light the time.On the contrary, in the time of the Heavy Weight of storage rack 6,, can strengthen spring force by spring force adjusting device 14.If press operating knob 34 once more, push rod 35 pushes away forward, and the hook portion 31 that is arranged on the lower end 32b of rocking arm 32 enters in the hook 37 of downwardly facing opening, and the rear wall 37b of hook 37 moves backward, hook 37 becomes the deformation state that long and short dash line m represents among Fig. 8 (a) once more, and slide bar 41 rearward d moves.At this moment, moving body 46 imports to guide groove 50 from the front side in conjunction with groove 49.Therefore, only press slide bar 41 from the place ahead, can be the moving body of torque spring 45, move to the stop groove 48 of rear side from the stop groove 49 of front side, hook 37 states that become down, the hook portion 31 of rocking arm 32 can break away from.At this moment, because the spring force of torsion spring 39, the く oxbow portion 52 of pushing up coil spring 15 in conjunction with protuberance 51 of the upper end 32a of rocking arm 32,11,15 two spring forces of coil spring act on the storage rack 6, increase spring force.

Therefore, when storage rack 6 is light, can move storage rack 6 to nadir at an easy rate, and Heavy Weight the time, switch spring force adjusting device 14, use the power littler than load, the operation that can pull on, thereby operability is fine.In addition, spring force adjusting device 14 can constitute one with connecting rod mechanism 5, can reduce number of parts, and only by pressing operating knob, energy regulating spring power is even operate the wrong damage that also do not have.In addition, the body part of spring force adjusting device 14 is arranged in the shaft seat 17, thereby outward appearance might as well.

The structure of spring force adjusting device is not limited to the example of Fig. 1, and as shown in Figure 9, an end of coil spring 11 is fixed on the axle 10 of rear linking rod 8, and the other end is connected on the shell 2 by spring force adjusting device 14.14 li of the spring force adjusting devices of Fig. 9 have the exterior operating knob 34 that is configured in shaft seat 17; By the axial region 60 of band external screw thread 60a, and this axle 60 joins with operating knob 34, and runs through the 17a of negative thread portion of shaft seat 17, is screwed to shaft seat 17 inside; Have the front end that is arranged on axial region 60 and with the other end く oxbow portion 52 of coil spring 11, the fit portion 61 of fit.If operating knob is rotated to clockwise direction, the external screw thread 60a of axle 60 is screwed into negative thread 17a, the く oxbow portion 52 that fit portion 61 promotes coil spring 11, and coil spring 11 acts on the spring force increase of storage rack 6 energetically; On the contrary, operating knob is pressed anticlockwise motion, axial region 60 withdraws, and the く oxbow portion 52 of coil spring 11 returns, and coil spring 11 unclamps, and the spring force that acts on storage rack 6 diminishes, and can be easy to adjust the spring force of coil spring 11.

In described the 1st embodiment, degree of freedom for the installation site of improving hinge 4 more, as Figure 11～shown in Figure 13, install with metal installation base plate 25 at the inner face of the side of shell 2 2a, on installation base plate 25 inner faces, fixed mechanism's cover cap, and mechanism's cover cap is in order to cover portions of mechanism such as coil spring 11,15 with screw.Mechanism's cover cap 29 becomes one with cylindrical portion 70, and this cylindrical portion 70 is in order to insert the front end that front rod 7 lower end 7b go up fixing axle 9.Other structure is identical with Fig. 1, the following describes different places.The lower end 7b of front rod 7 goes up and rotates fixing freely axle 9, is inserted into the 70 li energy of cylinder that are provided with on mechanism's cover cap 29 and freely rotates, and an end of axle 9 is completely fixed in installation base plate 25 with methods such as riveted joints.On this axle 9, by lining 81,, rotate freely and overlap in the above the lower end of front rod 7, on the other end 9b of axle 9, shell tool 82, fixing with E shape snap ring 105.

By the way, the past is as Figure 29, shown in Figure 30, on one end of the pitman 84 of connection left and right sides front rod 7, by adapter plate 90, with the method anchor shaft 9 of welding, and axle 9 passes through the axis hole of the lower end of front rod 7, shell tool 91, the bearing hole of insertion mechanism cover cap 29.In this case, the load that is added in front rod 7 concentrates on mechanism's cover cap 29, so in order to ensure the intensity of mechanism's cover cap 29, mechanism's cover cap 29 will be thickeied or shape will strengthen.But add the great institutions cover cap, as shown in figure 34, between mechanism's cover cap 29 and the hinge 4, can not guarantee required gap, the degree of freedom of the installation site of hinge 4 is restricted.

Different therewith, in the example as Figure 11～shown in Figure 13, at the mechanism's cover cap 29 that covers portions of mechanism such as coil spring, fixedly axle 9 cylindrical portion of passing through 70 of the lower end 7b of front rod 7 are integral, insert axle 9 the end of the front rod 7 of this cylindrical portion 70, method with riveted joint is fixed on installation base plate 25, so fixedly the axle 9 of the lower end 7b of front rod 7 is supported on cylindrical portion 70 and 25 two places of installation base plate of mechanism's cover cap 29, thereby the load dispersing that is applied to front rod 7 is accomplished thin typeization, the miniaturization of mechanism's cover cap 29 easily to installation base plate 25.And, can improve the degree of freedom of the installation site of hinge 4 because the miniaturization of mechanism's cover cap 29 as shown in figure 28, between mechanism's cover cap 29 and hinge 4, is guaranteed required interval easily.And because the axle 9 of front rod 7 is fixed on installation base plate 25, can accomplish the location of mechanism's cover cap 29 and the location of shock absorber easily by axle 9, not only improve the assembleability of lifting/lowering storage device, and the axle 9 of front rod 7 inserts the cylindrical portion 70 of mechanism's cover cap 29, so outward appearance U.S., mechanism's cover cap 29 is realized thin typeization, miniaturization, improves the outward appearance of lifting/lowering storage device.

In described the 1st enforcement state, in order to strengthen the gap between front rod 7 and the rear linking rod 8, as Figure 14, shown in Figure 15, aim on the one side of rear linking rod 8 at front rod 7, form recess 72, move to toward the front lower place under the state of extreme lower position when storage rack 6, can guarantee the gap E between front rod 7 and the rear linking rod 8.100 is the block of connecting rod mechanism among the figure, and 78 is the energy disperser cover cap.Other structure is identical with Fig. 1, narrates difference below.As Figure 31, shown in Figure 32, front rod 7 and rear linking rod 8 all are under the rectilinear situation, and when storage rack 6 was left behind toward the front lower place, the gap between front rod 7 and the rear linking rod 8 diminished gradually, when storage rack 6 is moved minimum position to, and gap E minimum, clip finger easily.Even change the installation site of front rod 7 and rear linking rod 8, want to increase gap E, because the installation site of hinge 4 can not increase gap E sometimes.In Figure 14, example shown in Figure 15, front rod 7 is facing to one side of rear linking rod 8, cut a part, form the simple structure of recess 72, when storage rack 6 is moved extreme lower position to toward the front lower place, also can guarantee the gap E between front rod 7 and the rear linking rod 8, do not change the installation site of front rod 7 and rear linking rod 8, can accomplish to prevent clip finger, increase the degree of freedom of the installation site of hinge 4 simultaneously, obtain the safety of use and advantage easy to use.As long as it is just passable to form recess 72 in about middle part of front rod 7, so constitute recess 72 with simple and cheap method.

In addition, in described the 1st embodiment, in order to strengthen the gap between front rod 7 and the rear linking rod 8, as Figure 16, shown in Figure 17, front rod 7 is from the rotary motion trace plane H of rear linking rod 8, and separately the back is crooked to the P direction.Like this, from about central portion of front rod 7 to end portion 73, outwards be bent into be roughly L shaped.That is to say that front rod 7 is to rotate respectively with rear linking rod 8, is laterally separated in parallel Different Plane.Like this, storage rack 6 is moved to toward front lower places when minimum, the dogleg section 73 of front rod 7 (the roughly part from the central portion to the lower end) is positioned at the oblique foreign side of rear linking rod 8, and it is big that the gap E between front rod 7 and the rear linking rod 8 becomes.Therefore, routine the same with described Figure 14, Figure 15 do not change the installation site of front rod 7 and rear linking rod 8, can guarantee the gap E of front rod 7 and rear linking rod 8, do not have the danger of clip finger, can improve the safety of using.And only bending front rod 7 just can, so can guarantee the gap E between front rod 7 and the rear linking rod 8 with simple, inexpensive structure.

Covering mechanism's cover cap 29 of portions of mechanism such as described shaft seat and coil spring and cover the energy disperser cover cap 78 of shock absorber, is to see from the side on mechanism's plate 24 of L font slightly to be arranged to one respectively.This mechanism's plate 24 is fixed on the inner face of the side 2a of shell 2 by installation base plate 25.

Installation base plate 25, for example shown in Figure 36, see slightly L font thin metallic plate (t=2) from the side, with self-tapping screw 106, be fixed on the side 2a of shell 2.Installation base plate 25 is when storage rack 6 is assembled into shell 2, and anti-locking mechanism plate 24 is run into the inner face of the side 2a of shell 2, stays the effect of scar for shell 2.The quantity of screw 106 is 6 in the example of Figure 36, but the quantity of screw 106 and installation site thereof are without limits.

On the face 24a of installation base plate 25 1 examples of mechanism's plate 24, formation can be held the recess 83 of the head 12a of described screw 106.At present embodiment, the position of each recess 83 is corresponding respectively with the head 12a of described 6 screws 106.Beyond each recess 83 on mechanism's plate 24, several (for example 5) screw hole 107 is arranged in other place, on the installation base plate 25 with on each screw hole 107 cooresponding position screw hole 112 is being arranged, screw 113 is from mechanism's plate 24, pass installation base plate, be fixed on the side 2a of shell 2, like this, energy disperser cover cap 78 reaches shock absorber and the mechanism's cover cap 29 that is covered by it and covers portions of mechanism such as shaft seat, coil spring by it, can be fixed on simultaneously on the side 2a of shell 2.

On the face 25a of mechanism's plate 24 1 sides of installation base plate 25, with the axle 9 corresponding positions of the lower end 7b of front rod 7 on, shown in Figure 37 (c), accommodation section 114 is set, wherein hold 9 o'clock outshot 108 (Figure 40) of riveted joint axle, like this, when installation base plate 25 and mechanism's plate 24 closely were adjacent to, the protrusion 108 that the riveted joint axle produced in 9 o'clock did not play blanketing.

In the lower end of installation base plate 25, shown in Figure 38 (a), leave on the direction of side 2a of shell 2 and be provided with the plate mounting portion of mechanism 104 that roughly becomes the L oxbow, in this plate mounting portion of mechanism 104, can promote the lower end 24c of carrying mechanism plate 24 freely.In addition, the front end of plate mounting portion of mechanism 104 is provided with shown in Figure 38 (b), and upwards crooked bending sheet 115 is arranged.Front end bottom at mechanism's plate 24, the linking part 116 that joins with described bending sheet 115 is set, the plate mounting portion of mechanism 104 that the bottom 24c of mechanism's plate 24 is rested installation base plate 25 pushes the place ahead (direction that the j of Figure 38 (b) represents) to, when linking part 116 is run into bent sheet 115,24 pairs of installation base plates 25 of mechanism's plate are correctly located, under this positioning states, each recess 83 of mechanism's plate 24, each head 12a of the screw 106 of aligning installation base plate 25.

But, on the installation base plate 25 side 24a of mechanism's plate 24, being provided with the recess 83 that holds screw 106 head 12a, this screw 106 is fixed on mechanism's plate 24 the side 2a of shell 2.Shown in Figure 37 (a), with screw 106 installation base plate 25 is fixed on shell 2 after, mechanism's plate 24 is fixed on the installation base plate 25.At this moment, shown in the arrow f of Figure 36, mechanism's plate 24 is crossed the bending sheet 115 of installation base plate 25, and the lower end 24c of mechanism's plate 24 rests the plate mounting portion of mechanism 104 of installation base plate 25, then, shown in arrow j among Figure 36, toward the place ahead pushing mechanism plate 24, the linking part 116 of mechanism's plate 24 is run into the bending sheet 115 of installation base plate 25, and 24 pairs of installation base plates 25 of mechanism's plate are in correct position and locate, each recess 83 of mechanism's plate 24 is just in time aimed at each head 12a of the screw 106 of installation base plate 25.Like this,, only run into bending sheet 115 and can judge that 83 li of recesses have accommodated the head 12a of screw 106 really, can prevent the mistake of constructing according to linking part 116 even can not see whether 83 li of recesses have taken in the head 12a of screw 106 from the outside with eyes.

As mentioned above, in 6 recesses 83 that are provided with on mechanism's plate 24, accommodate the head 12a of 6 screws 106 respectively, be not subjected to the influence of screw 106 head 12a, mechanism's plate 24 is close on the installation base plate 25.Afterwards, shown in Figure 37 (b), with screw 113, mechanism's plate 24, pass installation base plate 25, be fixed on screw on the side 2a of shell 2, like this, under the state that installation base plate 25 and mechanism's plate 24 are close to, mechanism's plate 24 is passed installation base plate 25, can be fixed on (state of Figure 35) on the shell 2, just from installation base plate 25 to mechanism's plate 24 sides, even the head 12a of screw 106 is outstanding,, can be close to mechanism's plate 24 on the installation base plate 25 because on mechanism's plate 24, be provided with the recess 83 that to accommodate this head 12a.

Therefore, fixed installation substrate 25 on the 2a of the side of shell 2, when in shell 2, assembling storage rack 6, can prevent that locking mechanism plate 24 runs into the inner face of the side 2a of shell 2 and produce scar, and under the construction state, can prevent producing the gap as before between locking mechanism plate 24 and the installation base plate 25, not only goodlooking, and enter insect in very close to each other or problem such as lay eggs.In when construction, the head 12a from the screw 106 of installation base plate 25 projections is covered by the recess 83 that is provided with on mechanism's plate 24, thus 24 pairs of installation base plates 25 of mechanism's plate, very fast can the location.The speed of the turn of the screw operation in the time of can improving fixed mechanism plate 24 can improve application property.

But, when mechanism's plate when being lamellar, on the installation base plate 25 side 24a of this mechanism's plate 24, recess 83 is set, shown in Figure 37 (b), on the back side 24b of the face 24a of installation base plate 25 sides of mechanism's plate 24, because recess 83, outstanding lug boss 117 influence attractive in appearancely, therefore preferably recess 83 is arranged in mechanism's plate 24 upper bumper cover caps 78 and reaches in mechanism's cover cap 29.As shown in figure 36, form 3 recesses 83 in the scope in mechanism's plate 24 upper bumper cover caps 78, and in mechanism's cover cap 29 scopes, form 3 recesses, like this, because the lug boss 117 that recess 83 is given prominence to, be cushioned device cover cap 78 and mechanism's cover cap 29 covers, cannot see from the outside, the outward appearance of mechanism's plate 24 is fine to be seen.

The 3rd embodiment of the present invention is shown in Figure 41～Figure 45.This lifting/lowering storage device, main body by the shell 2 of front openings, be installed in storage rack 6 in the shell 2, storage rack 6 is rotated freely with respect to shell 2 support, storage rack toward front lower place pulling connecting rod mechanism 5 freely, storage rack 6 constitutes from shell 2 rotates the oil brffer etc. of shock damping action when leaving behind toward front lower places shock absorber 12.In Figure 46, omitted cover cap shell 56.The basic structure of shell 2, storage rack 6, connecting rod mechanism 5, installation base plate 25 is the same with described the 1st embodiment, narrates difference below.

Be fixed on the axle 9 of lower end 7b of front rod 7, do not adorn mechanisms such as coil spring, supporting with free state with respect to shaft seat 17.And be fixed on the axle 10 of lower end 8b of rear linking rod 8, as shown in figure 41, the coil spring 11 of shock damping action when rotations are left behind from shell 2 toward front lower places is set storage rack 6.Coil spring 11 is installed in the shaft seat 17 that is provided with between the side 2a of shell 2 and the connecting rod mechanism 5.One end of coil spring 11 is fixed on shaft seat 17 inner spring fixed parts 28, and the other end is fixing to the axle 10 of rear linking rod 8, and like this, axle 10 directions that rearward lift of 11 pairs of rear linking rods 8 of coil spring apply spring force all the time.

On rear linking rod 8,, storage rack 6 is rotated shock damping action when leaving behind, is made up of oil brffer from shell 2 toward front lower places shock absorber 12 is set as Figure 41, shown in Figure 42.This shock absorber 12 is so-called Direct Action Type energy dispersers, the oil hydraulic cylinder 101 and the end that are supported on than the more close lower end position of the 10a of bearing portion of rear linking rod 8 by an end insert in the oil hydraulic cylinder 101, and other end 103a is supported on the piston rod 103 of the side 2a of shell 2 and constitutes by connecting element 71.

As shown in figure 43, insert the outside of the insertion section 118 of piston rod 103 on the oil hydraulic cylinder 101, form concave channels portion 119.Groove 119 is made of step 123 inwardly outstanding around the piston rod 103 and the leg 124 up more outstanding than stage portion 123, is provided with oil absorption material 120 in this concave channels portion 119.When rear linking rod 8 swings, the piston rod 103 and the oral area of oil hydraulic cylinder 101, with the rectangular directive effect power of axial a, when producing clearance G 1 between piston rod 103 and oil hydraulic cylinder 101, oil absorption material 120 absorbs from clearance G 1 oil spill, and the thickness d 1 of oil absorption material 120 is littler than the height of leg 124, oil absorption material 120 encases piston rod 103, and be arranged on the full week of concave channels portion 119, oil absorption material 120 is fixed in the concave channels portion 119, does not move with piston rod 103.The material of oil absorption material 120 does not have special restriction.

In the upper end of oil hydraulic cylinder 101 oil cap 77 is set.The effect of lid oil cap 77 is the telescopic movings in order to ensure piston rod 103; between piston rod 103 and oil cap 77, need to reserve necessary clearance G 2; so only by oil cap; can not be as recited above; during connecting rod swing since on the piston rod 103 of oil hydraulic cylinder 101 effect and the axial a direction b application force that meets at right angles; can prevent leakage of oil when between piston rod 103 and oil hydraulic cylinder 101, producing clearance G 1, this with prevent that the oil absorption material 120 from clearance G 1 leakage of oil is different.This oil cap 77 is what to separate with oil hydraulic cylinder 101, can certainly be integral.

As shown in figure 41, end at oil hydraulic cylinder 101 is provided with attaching parts 126, and this attaching parts 126 is given prominence to by the peristome 56b that is arranged on the cover cap shell 127 that covers oil hydraulic cylinder 101 free to advance or retreatly, and the front end of attaching parts 126 is supported on the position P than the bearing portion more close lower end of 10a of rear linking rod 8.On this attaching parts 126, as Figure 42, Figure 44, shown in Figure 45, when attaching parts 126 when the peristome 56b of cover cap shell 127 moves on to extrusion position, on the position with respect to peristome 56b and cover cap shell 127 inboards, be provided with the protuberance 128 of retaining oil.This retaining oil is to form ring-type on the full week of attaching parts 126 with protuberance 128, and its effect is along oil hydraulic cylinder 101 outside faces, the oil that flows down from above, and retaining is fallen in the cover cap shell 127 at the outside face of attaching parts 126.

As shown in figure 41, cover cap shell 127 has the size that can hold the whole shock absorbers 12 that comprise oil hydraulic cylinder 101 and piston rod 103, its bottom 56a becomes dish type, the peristome 56b of described attaching parts 126 turnover is positioned at the front of the top of bottom 56a, and the oil that flows down from above all falls into the tray-shaped bottom of cover cap shell 127.

The outside of the insertion section 118 of the piston rod 103 of insertion oil hydraulic cylinder 101, be provided with the concave channels portion 119 that encases piston rod 103, in this concave channels portion 119, oil absorption material 120 is set, so during connecting rod swing, go up application force with the rectangular direction b of axial a of the piston rod 103 of oil hydraulic cylinder 101, even between piston rod 103 and oil hydraulic cylinder 101, produce clearance G 1, from the oil of this clearance G 1 outflow, all held, prevent the outside of oil leakage really to oil hydraulic cylinder 101 by oil absorption material 120.Because groove 119 is made concavity, even the oil in the oil absorption material 120 exceeds capacity perhaps, oil is not easy to spill from groove 119, and on the rectangular direction b of the axial a of oil hydraulic cylinder 101 in the application force, piston rod 103 is flexible, between piston rod 103 and oil hydraulic cylinder 101 during generation clearance G 1, and the oil that overflows from oil absorption material 120, flow back in the oil hydraulic cylinder 101 from this clearance G 1, so the oil absorbency of energy long term maintenance oil absorption material 120.Oil absorption material 120 occluded oils so piston rod 103 contacts with oil absorption material, owing to the lubricant effect of oil, can be guaranteed piston rod movement freely.

The oil of described oil absorption material 120 becomes saturation conditions, just in case oil leakage is during to the outside of oil hydraulic cylinder 101, oil flows to the bottom of oil hydraulic cylinder 101, through attaching parts 126, flows in the shell 2.In the present embodiment, the root of the attaching parts 126 that the peristome 56b that is provided with from cover cap shell 127 gives prominence to free to advance or retreatly, just attaching parts 126 is from the peristome 56b of cover cap shell 127 when the most outstanding, on the corresponding position of inner side of peristome 56b and cover cap shell 127, be provided with the protuberance 128 of the oily usefulness of retaining, so through attaching parts 126, flow to the oil in cover cap shell 127 outsides, run into the protuberance 128 of the oily usefulness of retaining, can not readvance, from oil hydraulic cylinder 101 oil spills, all accumulate in the cover cap shell 127 that covers oil hydraulic cylinder 101.

That is to say, from oil hydraulic cylinder 101 inner oil spills, prevent leakage of oil by the oil absorption material 120 that is provided with on piston rod 103 insertion sections 118 of inserting oil hydraulic cylinder 101, and in the outside of oil hydraulic cylinder 101, because retaining oil with protuberance 128, can prevent that oil from spilling toward the outside of cover cap shell 127, become the double leak-proof structure of using protuberance 128 with oil absorption material 120 and retaining oil, can keep the good and cleaning of outward appearance of shell 2, and can not bring unhappy sensation to the user because of greasy dirt.

As mentioned above, insert on the insertion section 118 of piston rod 103, oil absorption material 120 is installed at oil hydraulic cylinder 101, retaining oil protuberance 128 is set on the attaching parts 126 of oil hydraulic cylinder 101, so, the leakproof problem of lifting/lowering storage device, can just can realize with inexpensive structure, can cost-cutting.

In this 3rd embodiment, the example that oil hydraulic cylinder 101 is set has been described, but it is good to be arranged on front rod 7 on rear linking rod 8, perhaps on front rod and rear linking rod, all be provided with also passable.
