As shown in Figure 9, the buffer unit 20 of assembling forms total length 70mm, the roughly corner post shape of about 30mm on one side like this, compare with buffer unit such as existing gas spring because small-sized and light weight, therefore carrying or take care of etc. easy to use.
And above-mentioned buffer unit 20 can omit the installation as the bracing frame 7 of action component when assembling is finished, and therefore promotes miniaturization and, uses convenient.
Before above-mentioned buffer unit 20 is installed, i.e. before the folding table assembling, as mentioned above, separate use with bracing frame 7 as action component, bracing frame 7 does not insert main body 21 and movable body 22.
And, after buffer unit 20 assemblings, with the fork sheet 44 insertion main bodys 2 of engagement device 25, movable body 22 is fastened on this fork sheet 44 and pushes to, the tapered portion 39 of downside that is installed on the retainer 23 of movable body 22 contacts with one side of holding section 47, and the point of tapered portion 39 snaps in the through hole 48.
Under the situation of using buffer unit 20 like this, bracing frame 7 is inserted main body 21 and movable body 22, the one end becomes the free end that can be connected in the pillar 8, be configured in the downside of main body 21, the other end protrudes in the outside of main body 21, and its protuberance is connected in functional component such as desktop 1.
Above-mentioned bracing frame 7 is being inserted under the situation of main body 21 and movable body 22; be installed at engagement device 25 under the state of main body 21; guarantee that promptly bracing frame 7 inserts under the state in space of inboard of movable bodys 22, with bracing frame 7 from the top of over cap 24 or the below of the minor diameter part 21a of main body 21 insert.
And, make bracing frame 7 insert logical movable bodys 22, outstanding from over cap 24, the appropriate location of this protuberance directly or indirectly is connected in the functional component of desktop 1 etc., the bottom is configured in the outside of main body 21.
Like this, because engagement device 25 is installed on main body 21, and guarantee that bracing frame 7 inserts the space of the inboard of movable bodys 22, therefore can be easily and promptly insert bracing frame 7.
Like this, after the part with bracing frame 7 directly or indirectly is connected in desktop 1 grade, keep handle part 45 and stretching laterally, will pitch sheet 44 and extract, engagement device 25 is taken off from main body 21 from slot 29.
Like this, fork sheet 44 is extracted from slot 29, and movable body 22 is pushed the height of pitching sheet 44 by spring 34, moves along bracing frame 7, and retainer 23 together moves, and the tapered portion 39 of downside moves downwards.
Therefore, the tabular surface 23a of retainer 23 to the medial movement of main body 21, pushes the outer peripheral face of the bracing frame 7 of subtend corresponding to the below displacement of tapered portion 39.
Promptly, this situation is equivalent to tapered portion 39 and inserts state between one side of inner face of the outer peripheral face of bracing frame 7 and holding section 47 as wedge, its interface pressure is realized buffering or braking action by the outer peripheral face that the tabular surface 23a of retainer 23 acts on the bracing frame 7 of subtend.
In this case, the movable body 22 of embodiment is provided with retainer 23 on one side, and its tabular surface 23a is connected airtight in one side of the outer peripheral face of bracing frame 7, but, also can retainer 23 be set on relative edge or each limit of movable body 22, and its each tabular surface 23a is connected airtight in the outer peripheral face of bracing frame 7, strengthen buffering or braking action.
As implement mode tilted configuration buffer unit 20, and under the situation of tilted configuration main body 21,22 and bracing frame 7, the retainer 23 of upside that is positioned at bracing frame 7 by gravity to bracing frame 7 side shiftings, and its tabular surface 23a is connected airtight in the outer peripheral face of the upside of bracing frame 7, therefore compare with the vertical situation that buffer unit 20 is set, buffering or braking action that retainer 23 produces have been strengthened, even under the situation of the embodiment on the one side that retainer 23 is arranged at movable body 22 upsides, also buffering that can obtain to expect or braking action.
Like this, with engagement device 25 after main body 21 is taken off, by bracing frame 7 is moved up and down, can obtain concrete buffering or braking action that retainer 23 produces.
For example, when desktop 1 is folding, when keeping desktop 1 and upwards foldingly rotate and bracing frame 7 is together moved and when moving up, the friction that retainer 23 produces by bracing frame 7 and being pulled on slightly, tabular surface 23a moves laterally corresponding to its displacement, thereby leaves the outer peripheral face of bracing frame 7.
As a result, buffering that retainer 23 produces or braking action disappear or reduce, easily and promptly folding desktop 1.
On the other hand, after desktop 1 folds, under the situation that it is launched to use, when moving down when keeping handle 17 to rotate and make bracing frame 7 together to move desktop 1, retainer 23 is left behind by the friction of bracing frame 7 generations, tabular surface 23a moves to the inside corresponding to the below displacement of tapered portion 39, thus the outer peripheral face of pushing bracing frame 7.
Promptly, this situation is equivalent to tapered portion 39 and inserts state between one side of inner face of the outer peripheral face of bracing frame 7 and holding section 47 as wedge, its interface pressure is realized buffering or braking action by the outer peripheral face that the tabular surface 23a of retainer 23 acts on the bracing frame 7 of subtend.
Therefore, the moving down of bracing frame 7 is braked and slows down, and desktop 1 slowly rotates, and the fastening portion (diagram is omitted) that the bottom of bracing frame 7 is connected in the pillar 8 is static afterwards, keeps the level of desktop 1.
In this case, a part of side face of bracing frame 7 is sticked in protuberance 49 and is felt relieved, and the moving by protuberance 48,48 restrictions of the left and right directions of retainer 23, and these parts successfully move.
And buffer unit 20 of the present invention can decompose folding table and take off and discard in that function worsens when carrying out waste treatment through using throughout the year, perhaps each component part is decomposed or disintegration and discarding.In either case, because buffer unit 20 small-sized light weights, so processing ease, and, because the trouble that gases at high pressure or action oil are discharged the existing buffer unit of picture not, and do not forget explosion accident under the situation or injured problem, so can discard safely.
On the other hand, when before the folding table assembling of the present invention that will have above-mentioned buffer unit 20, delivering, can be with the separately delivery together of a plurality of assemblies.
For example, with buffer unit 20 as above-mentioned assembling, engagement device 25 is installed on its main body 21 and bracing frame 7 is not installed under the state of buffer unit 20, the upper end open of over cap 24 is placed.
And, the upper end of pillar 8 is embedded in the minor diameter part 21a of above-mentioned buffer unit 20, the engaging protrusion 27 of tongue piece 26 is sticked in its through hole 28, and both are connected.
At this moment, when engaging protrusion 27 was sticked in the inner face of pillar 8, tongue piece 26 was displaced to the inboard of minor diameter part 21a and allows above-mentioned engaging, after engaging protrusion 27 is sticked in through hole 8, tongue piece 26 is because elasticity is restored laterally, and engaging protrusion 27 is sticked in through hole 28, and main body 21 is connected with pillar 8.
Then, Caster 9 is installed in the bottom of above-mentioned pillar 8, pair of frames joint 11 is installed, insert box joint 13 in an end of this joint 11 and be spirally connected, the bottom of bracing frame 6 is rotatably connected between the tab 15,15 in the centre position of this pillar 8.
And, the box joint 13,13 of above-mentioned pair of posts assembly is inserted at the both ends of crossbearer 14, and one connects by being spirally connected with these parts.
And, the bracing frame 2,3 and the handle 17 of pair of right and left are installed in the inside of desktop 1, the two ends mounting bracket 4 of a bracing frame 3 therein is connected in this support 4, assembling desktop assembly on strut assemblies rotationally with the upper end of above-mentioned bracing frame 6.
On the other hand, another support 5 separates in the mode that is not installed on desktop 1, and the upper end of bracing frame 7 is connected in this support 5 rotationally, and back batter 12 separates in the mode that is not installed on pillar 8, Caster 10 is installed by portion in its back-end, and these bracing frames 7 are packed with above-mentioned desktop assembly with the assembly of back batter 12.
At this moment, bracing frame 6,6 is that rotate at the center with picture 15,15, and desktop 1 be that rotate at the center with support 4, and desktop 1 and bracing frame 6,6 and pillar 8,8 configured in parallel fold the desktop assembly compactly, have realized the miniaturization of packing.This situation is identical with the folding situation of the folding table of Figure 14.
Under the situation of the above-mentioned package member of assembling; the bottom of bracing frame 7 can be inserted the top peristome of over cap 24; and be inserted into the below of pillar 8; and the upper end of bracing frame 7 is connected in support 5 rotationally; this support 5 is installed on the assigned position of the inside of desktop 1, and an end of back batter 12 is bolted in the outside of said frame joint 11.
In this case, because engagement device 45 is installed on buffer unit 20, and guarantee that bracing frame 7 inserts the volume inside of movable body 22, so the insertion of bracing frame 7 is also promptly carried out easily.
As shown in Figure 1 and Figure 2, Zu Zhuan folding table is at the outside of pillar 8 configuration buffer unit 20 like this, because the miniaturization and of buffer unit 20, therefore compare with the situation that buffer unit 20 is configured in the inboard of pillar 8, realize the pathization of pillar 8, and realized the raising and the lightweight of the design of folding table.
In this case, even buffer unit 20 is configured in the outside of pillar 8,, does not therefore feel inharmonious, and do not influence the outward appearance of folding table yet because buffer unit 20 is small-sized.
And, the cam mechanism of the expanded position of desktop 1 and folding position without limits in above-mentioned folding table, so number of components reduces, and constitutes succinct.
On the other hand, as Fig. 4, shown in Figure 5, in the folding table after assembling, engagement device 25 is installed on buffer unit 20, and buffer unit 20 does not play a role because retainer 23 separates with bracing frame 7, therefore when reality is used, need take off engagement device 25.
Under the situation of taking off above-mentioned engagement device 25,, and will pitch sheet 44 and extract just passable from slot 29 as long as keep handle part 45 and stretching laterally.
Like this, fork sheet 44 is extracted from body 21, and movable body 22 is pushed the height of pitching sheet 44 by spring 34, moves along bracing frame 7, and retainer 23 together moves, and the tapered portion 39 of downside moves downwards.
This situation such as Fig. 6, shown in Figure 7, the tabular surface 23a of retainer 23 to the medial movement of main body 21, push the outer peripheral face of the bracing frame 7 of subtend corresponding to the below displacement of tapered portion 39.
Promptly, this situation is equivalent to tapered portion 39 and inserts state between one side of inner face of the outer peripheral face of bracing frame 7 and holding section 47 as wedge, its interface pressure is realized buffering or braking action by the outer peripheral face that the tabular surface 23a of retainer 23 acts on the bracing frame 7 of subtend.
In this case, the movable body 22 of embodiment is provided with retainer 23 on one side, and make its tabular surface 23a be pushed on one side of the outer peripheral face of bracing frame 7, but, also can retainer 23 be set on the relative edge or four limits of movable body 22, and its each tabular surface 23a is connected airtight in the outer peripheral face of bracing frame 7, strengthen buffering or braking action.
As implement mode tilted configuration buffer unit 20, and under the situation of interior main body 21,22 of tilted configuration and bracing frame 7, the retainer 23 of upside that is positioned at bracing frame 7 by gravity to bracing frame 7 side shiftings, and its tabular surface 23a is connected airtight in the outer peripheral face of the upside of bracing frame 7, therefore compare with the vertical situation that buffer unit 20 is set, buffering or braking action that retainer 23 produces have been strengthened, even retainer 23 is arranged at one side of movable body 22 upsides, also buffering that can obtain to expect or braking action.
Like this, with engagement device 25 after main body 21 is taken off, by bracing frame 7 is moved up and down, can obtain the buffering or the braking action of the reality that retainer 23 produces.
For example, when desktop 1 folds, is that center when upwards rotating with desktop 1 with the articulated section of the upper end of bracing frame 6 when keeping handle 17, bracing frame 7 stretches out upward from buffer unit 20, the friction that retainer 23 produces by bracing frame 7 and being pulled on slightly, tabular surface 23a moves laterally corresponding to its displacement and leaves the outer peripheral face of bracing frame 7.
This situation as shown in figure 13, tapered portion 39 is extracted between bracing frame 7 and holding section 47 slightly, its wedge effect reduces or disappears, buffering that tapered portion 39 produces or braking action reduce or disappear, easily and promptly folding desktop 1.
Like this, when desktop 1 upwards rotates and bracing frame 7 when outstanding upward, the rearward end of desktop 1 rises, and its leading section is pulled to pillar 8 sides, and bracing frame 6 is that middle mind-set pillar 8 sides are rotated with the pivot branch of tab 15, desktop 1 moves to the position parallel with pillar 8, bracing frame 6 moves to the position parallel with pillar 8, and afterwards, desktop 1 stops operating, desktop 1 is parallel with bracing frame 6 with pillar 8 or bracing frame 7, and desktop 1 is folded.
This situation such as Figure 14 and shown in Figure 15, the articulated section of the upper end of bracing frame 6 is positioned at four dead points of saving rotational coupling mechanisms that formed by desktop 1 and pillar 8 or bracing frame 7 and bracing frame 6 and tab 15, only otherwise make the masterpiece of certain orientation be used for above-mentioned articulated section, just can keep the folded state of desktop 1.
On the other hand, after desktop 1 folds, with under its situation of launching to use, when keeping handle 17 to leave behind for propping up the desktop 1 of naming a person for a particular job with the articulated section of the upper end of bracing frame 7, the leading section of desktop 1 is that fulcrum upwards rotates with above-mentioned articulated section, the upper end of bracing frame 6 is drawn obliquely, and bracing frame 6 is that forwards rotate at the center with the pivot branch of tab 15.
And, when desktop 1 is further left behind, when bracing frame 6 further forwards rotates, the weight of desktop 1 and the power of leaving behind act on bracing frame 7 effectively by support 5, bracing frame 7 is pushed down, and moves in the inside of buffer unit 20.
Like this, retainer 23 is left behind by the friction of bracing frame 7 generations, and tapered portion 39 is pushed between bracing frame 7 and the holding section 47, and tabular surface 23a moves to the inside corresponding to the below displacement of this tapered portion 39, the outer peripheral face of pushing bracing frame 7.
Promptly, this situation is equivalent to tapered portion 39 and inserts state between the inner face of the outer peripheral face of bracing frame 7 and holding section 47 as wedge, its interface pressure cushions or brakes moving down of bracing frame 7 by the outer peripheral face that the tabular surface 23a of retainer 23 acts on the bracing frame 7 of subtend.
At this moment, a part of side face of bracing frame 7 is sticked in protuberance 49 and is felt relieved, and the moving by protuberance 48,48 restrictions of the left and right directions of retainer 23, and these parts successfully move.
Therefore, bracing frame 7 is braked and slowly moves down, and slowly upwards rotation of desktop 1, and the fastening portion (diagram is omitted) that the bottom of bracing frame 7 is connected in the pillar 8 is static afterwards, and bracing frame 6 stops operating, and keeps its level in supporting desktop 1.This situation such as Fig. 1 and shown in Figure 2.
Such a folding table of the present invention, by small-sized light weight and cheap buffer unit 20, the effect of buffer unit 20 is disappeared or reduction, can be easily and folding desktop 1 promptly, and when desktop 1 uses, buffer unit 20 is played a role, can be safely and launch desktop 1 lentamente.
