In figure, 45 is the handle part that is based in the outside of engagement device 25.
Above-mentioned engagement device 25, before bracing frame 7 inserts, is installed on main body 21 in the mode of fork sheet 44 being inserted to slot 29, and movable body 22 is positioned on fork sheet 44 retainer 23 is together moved, and makes the tabular surface 23a displacement laterally of retainer 23.
And in figure, 48 is the reinforcement (bead) projecting vertically in a side of above-mentioned holding section 47, can engagingly be disposed at the two sides of above-mentioned tapered portion 39, can limit the movement of tapered portion 39.49 is the reinforcement axially projecting at three edges of above-mentioned holding section 47, can engagingly be disposed at the outer peripheral face of above-mentioned bracing frame 7, can feel relieved to this bracing frame 7.
And, although the folding table of this embodiment configures respectively bracing frame 6,7 and pillar 8 obliquely, but also can arranged perpendicular bracing frame 7 and pillar 8, and arranged perpendicular buffer unit 20, by using like this, except folding table, buffer unit 20 can also be used in to the upper-lower position adjustment buffer unit of the seat portion of for example chair.
The major part of the buffer unit of the present invention forming like this; formed by main body 21 and 22, retainer 23, over cap 24 and engagement device 25, because therefore these parts are by ester moulding; for carrying out mass production with light weight, can cheaply also easily evenly make these parts.
Then, as shown in Figure 8, by these assembling parts in the situation that, first the fork sheet 44 of engagement device 25 is inserted to the slot 29 of main body 21, the bottom of this fork sheet 44 is housed in to the end difference in main body 21.
Afterwards, the avris by spring accepting hole 32 towards slot 29, is inserted into movable body 22 in main body 21, and the notch 22a of the bottom of this movable body 22 is engaged and be contained in the protuberance 44a of fork sheet 44.
Now, the backfall of retainer 23 is embedded in advance to the embeded slot 31 of movable body 22, the engagement pin 37 of the bottom that is based in embeded slot 31 is inserted to the open-work 36 that is formed at engaging groove 35, and by retainer 23 engagings in embeded slot 31.
In assembling when above-mentioned retainer 23, according to the weight of desktop 1 of load that is equivalent to buffer unit 20, select the tapered portion 38,39 of retainer 23 to assemble.
; the angle of taper difference of tapered portion 38,39; in the case of the weight of desktop 1 is larger; need larger cushion effect or brake force; therefore tapered portion less angle of taper 39 is configured in to downside; in the case of the weight of desktop 1 is less, less cushion effect or brake force are just enough, therefore tapered portion larger angle of taper 38 are configured in to downside.
In embodiment, because the weight of desktop 1 is larger, therefore need larger cushion effect or brake force, thereby tapered portion less angle of taper 39 is configured in to downside.
And; after spring 34 is inserted to the spring accepting hole 32 of above-mentioned movable body 22; over cap 24 is inserted to the upper end of main body 21; the upper end of spring 34 is contained in to spring accepting hole 41; locking pawl 40 is sticked in to the connecting hole 30 of main body 21 from inner side; by being connected in main body 21, a series of assembling of buffer unit 20 completes.
The assembling of such a buffer unit 20, to be undertaken by the simple operations of each component parts being inserted and engage, owing to not needing to enclose gases at high pressure or action oil as existing buffer unit, therefore form simple, do not need special equipment, and can simply and promptly carry out.
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, and compared with the buffer unit such as existing gas spring, due to small-sized and light weight, therefore carrying or keeping etc. is easy to use.
And above-mentioned buffer unit 20, in the time that assembling completes, can omit the installation as the bracing frame 7 of action component, therefore promotes miniaturization and, uses convenient.
Before above-mentioned buffer unit 20 is installed, i.e. before folding table assembling, as mentioned above, separate use with the 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, the fork sheet 44 of engagement device 25 is inserted to main body 2, movable body 22 is fastened on this fork sheet 44 and pushes to, the tapered portion 39 that is installed on the downside of the retainer 23 of movable body 22 contacts with one side of holding section 47, and the point of tapered portion 39 snaps in through hole 48.
In the situation that using like this buffer unit 20, bracing frame 7 is inserted to main body 21 and movable body 22, one end becomes the free end that can be connected in pillar 8, be configured in the downside of main body 21, the other end protrudes from the outside of main body 21, and its protuberance is connected in the functional component such as desktop 1.
In the situation that above-mentioned bracing frame 7 being inserted to main body 21 and movable body 22; be installed at engagement device 25 under the state of main body 21; guarantee that bracing frame 7 inserts under the state in space of the inner side of movable body 22, by 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 movable body 22, outstanding from over cap 24, the appropriate location of this protuberance directly or is indirectly connected in to the functional component of desktop 1 etc., bottom is configured in to the outside of main body 21.
Like this, due to engagement device 25 is installed on to main body 21, and guarantee that bracing frame 7 inserts the space of the inner side of movable body 22, therefore can easily and promptly insert bracing frame 7.
Like this, after a part for bracing frame 7 being directly or indirectly connected in to desktop 1 grade, keeping handle part 45 and stretch laterally, fork sheet 44 is extracted from slot 29, engagement device 25 is taken off from main body 21.
Like this, fork sheet 44 is extracted from slot 29, and movable body 22 is pushed the height of fork sheet 44 by spring 34, move 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, corresponding to the below displacement of tapered portion 39, to the medial movement of main body 21, pushes the outer peripheral face of the bracing frame 7 of subtend.
; this situation is equivalent to tapered portion 39 and inserts the state between the outer peripheral face of bracing frame 7 and one side of the inner face of holding section 47 as wedge; its interface pressure acts on the outer peripheral face of the bracing frame 7 of subtend by the tabular surface 23a of retainer 23, realize buffering or braking action.
In this case, the movable body 22 of embodiment arranges 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 the relative edge of movable body 22 or each limit, and its each tabular surface 23a is connected airtight in the outer peripheral face of bracing frame 7, strengthen buffering or braking action.
As embodiment tilted configuration buffer unit 20, and in 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 compared with the vertical situation that buffer unit 20 is set, buffering or braking action that retainer 23 produces are strengthened, even in the case of retainer 23 being arranged to the embodiment on one side of movable body 22 upsides, also can obtain buffering or the braking action of expectation.
Like this, by 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, in the time that desktop 1 is folding, when keeping desktop 1 and upwards foldingly rotating and bracing frame 7 together moved and while 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, the buffering that retainer 23 produces or braking action disappear or reduce, easily and promptly folding desktop 1.
On the other hand, after desktop 1 is folding, in the situation that being launched to use, while moving down when keeping handle 17 to rotate and make bracing frame 7 together to move desktop 1, the friction that retainer 23 produces by bracing frame 7 and being left behind, 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.
; this situation is equivalent to tapered portion 39 and inserts the state between the outer peripheral face of bracing frame 7 and one side of the inner face of holding section 47 as wedge; its interface pressure acts on the outer peripheral face of the bracing frame 7 of subtend by the tabular surface 23a of retainer 23, realize buffering or braking action.
Therefore, the moving down of bracing frame 7 is braked and slows down, and desktop 1 slowly rotates, and it is static afterwards that the bottom of bracing frame 7 is connected to engaging portion (diagram is omitted) in pillar 8, maintains 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 movement of the left and right directions of retainer 23 is by protuberance 48,48 restriction, and these parts successfully move.
Buffer unit 20 small-size light-weights of the present invention, and can cheaply make, in use, in the time that the bracing frame 7 as action component moves up, buffering or braking action are removed or are reduced, bracing frame 7 is easily also promptly moved up, easily folding desktop 1, on the other hand, in the time that bracing frame 7 moves down, buffering or braking action recover or strengthen, and bracing frame 7 safety also move down lentamente, can launch lentamente desktop 1.
And buffer unit 20 of the present invention, function worsens while carrying out waste treatment through using throughout the year, can decompose folding table and take off and discard, or each component part is decomposed or disintegration and discarding.In either case, due to buffer unit 20 small-size light-weights, therefore processing ease, and, due to the trouble that gases at high pressure or action oil are discharged as existing buffer unit not, and do not forget explosion accident in situation or injured problem, therefore can discard safely.
On the other hand, while delivery before the folding table of the present invention with above-mentioned buffer unit 20 is assembled, can be by the separately delivery together of multiple assemblies.
For example, by buffer unit 20 as above-mentioned assembling, engagement device 25 is installed on to 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 to the minor diameter part 21a of above-mentioned buffer unit 20, the engaging protrusion of tongue piece 26 27 is sticked in to its through hole 28, and both are connected.
Now, in the time that engaging protrusion 27 is sticked in the inner face of pillar 8, tongue piece 26 is displaced to the inner side 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, in the bottom of above-mentioned pillar 8, Caster 9 is installed, in the centre position of this pillar 8, pair of frames joint 11 is installed, insert box joint 13 and be spirally connected in an end of this joint 11, the bottom of bracing frame 6 is rotatably connected between tab 15,15.
And, the both ends of crossbearer 14 are inserted to the box joint 13,13 of above-mentioned pair of posts assembly, and one connects by being spirally connected by these parts.
And, 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 rotationally by the upper end of above-mentioned bracing frame 6, assembles desktop component in strut assemblies.
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 to this support 5 rotationally, and rear 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 together with above-mentioned desktop component with the assembly of rear batter 12.
Now, bracing frame 6,6 rotates centered by picture 15,15, and desktop 1 rotates centered by support 4, and desktop 1 and bracing frame 6,6 and pillar 8,8 configured in parallel are folding compactly by desktop component, have realized the miniaturization of packing.This situation is identical with the folding situation of the folding table of Figure 14.
The in the situation that of the above-mentioned package member of assembling; the bottom of bracing frame 7 can be inserted to the peristome above of over cap 24; and be inserted into the below of pillar 8; and the upper end of bracing frame 7 is connected in to support 5 rotationally; this support 5 is installed on to the assigned position of the inside of desktop 1, and an end of rear batter 12 is bolted in to the outside of said frame joint 11.
In this case, due to engagement device 45 being installed on buffer unit 20, and guarantee that bracing frame 7 inserts the space of the inside of movable body 22, therefore the insertion of bracing frame 7 is easily also promptly carried out.
As shown in Figure 1 and Figure 2, the folding table of assembling is at the outside of pillar 8 configuration buffer unit 20 like this, due to the miniaturization and of buffer unit 20, therefore compared with the situation of inner side that is configured in pillar 8 with buffer unit 20, realize the path of pillar 8, and realized raising and the lightweight of the design of folding table.
In this case, even if buffer unit 20 is configured in to the outside of pillar 8, because buffer unit 20 is small-sized, therefore do not feel inharmonious, and do not affect the outward appearance of folding table yet.
And, in above-mentioned folding table, do not limit the expanded position of desktop 1 and the cam mechanism of folding position, therefore number of components reduces, and forms succinct.
On the other hand, as shown in Figure 4, Figure 5, in the folding table after assembling, engagement device 25 is installed on buffer unit 20, and because retainer 23 separates with bracing frame 7, buffer unit 20 does not play a role, and therefore, in the time that reality is used, need to take off engagement device 25.
In the situation that taking off above-mentioned engagement device 25, as long as keep handle part 45 and stretch laterally, and fork sheet 44 is extracted just passable from slot 29.
Like this, fork sheet 44 is extracted from body 21, and movable body 22 is pushed the height of fork sheet 44 by spring 34, move along bracing frame 7, and retainer 23 together moves, and the tapered portion 39 of downside moves downwards.
As shown in Figure 6, Figure 7, the tabular surface 23a of retainer 23, corresponding to the below displacement of tapered portion 39, to the medial movement of main body 21, pushes the outer peripheral face of the bracing frame 7 of subtend to this situation.
; this situation is equivalent to tapered portion 39 and inserts the state between the outer peripheral face of bracing frame 7 and one side of the inner face of holding section 47 as wedge; its interface pressure acts on the outer peripheral face of the bracing frame 7 of subtend by the tabular surface 23a of retainer 23, realize buffering or braking action.
In this case, the movable body 22 of embodiment arranges 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 the relative edge of movable body 22 or four limits, and its each tabular surface 23a is connected airtight in the outer peripheral face of bracing frame 7, strengthen buffering or braking action.
As embodiment tilted configuration buffer unit 20, and in the situation of the 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 compared with the vertical situation that buffer unit 20 is set, buffering or braking action that retainer 23 produces are strengthened, even if retainer 23 is arranged to one side of movable body 22 upsides, also can obtain buffering or the braking action of expectation.
Like this, by engagement device 25 after main body 21 is taken off, by bracing frame 7 is moved up and down, can obtain actual buffering or braking action that retainer 23 produces.
For example, in the time that desktop 1 is folding, in the time keeping handle 17 that desktop 1 is upwards rotated centered by the articulated section of the upper end of bracing frame 6, 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, extract slightly between bracing frame 7 and holding section 47 by tapered portion 39, and its wedge effect reduces or disappears, and the 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 when bracing frame 7 is outstanding upward, the rearward end of desktop 1 rises, and its leading section is pulled to pillar 8 sides, and bracing frame 6 rotates to pillar 8 sides centered by 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 is as shown in Figure 14 and Figure 15, the articulated section of the upper end of bracing frame 6 is positioned at the dead point of the four joint 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 for above-mentioned articulated section, just can maintain the folded state of desktop 1.
On the other hand, after desktop 1 is folding, is launched use in the situation that, in the time keeping handle 17 to leave behind as propping up the desktop 1 of naming a person for a particular job taking the articulated section of the upper end of bracing frame 7, the leading section of desktop 1 upwards rotates taking above-mentioned articulated section as fulcrum, the upper end of bracing frame 6 is drawn obliquely, and bracing frame 6 forwards rotates centered by the pivot branch of tab 15.
And when desktop 1 is further left behind, bracing frame 6 is while further forwards rotating, 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, the friction that retainer 23 produces by bracing frame 7 and being left behind, tapered portion 39 is pushed between bracing frame 7 and 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.
; this situation is equivalent to tapered portion 39 and inserts the state between the outer peripheral face of bracing frame 7 and the inner face of holding section 47 as wedge; its interface pressure acts on the outer peripheral face of the bracing frame 7 of subtend by the tabular surface 23a of retainer 23, buffering or the moving down of brake support rack 7.
Now, a part of side face of bracing frame 7 is sticked in protuberance 49 and is felt relieved, and the movement of the left and right directions of retainer 23 is by protuberance 48,48 restriction, and these parts successfully move.
Therefore, bracing frame 7 is braked and slowly moves down, and desktop 1 slowly upwards rotates, and it is static afterwards that the bottom of bracing frame 7 is connected to engaging portion in pillar 8 (diagram is omitted), and bracing frame 6 stops operating, in supporting desktop 1, maintain its level.This situation as shown in Figure 1 and Figure 2.
Such a folding table of the present invention, by small-size light-weight and cheap buffer unit 20, in the time that desktop 1 is folding, make the effect of buffer unit 20 disappear or reduce, can be easily and folding desktop 1 promptly, and in the time that desktop 1 uses, make buffer unit 20 play a role, can launch safely and lentamente desktop 1.
Utilizability in industry
The formation of buffer unit of the present invention is simple, can easily and at an easy rate make, can realize its miniaturization and and easily carry out waste treatment simultaneously, and, folding table of the present invention utilizes this buffer unit carry out the folding operation of desktop and launch operation, realize its operate smoothly with security in, form simple and can easily and at an easy rate make, realize the raising of its miniaturization and and design.
