The specific embodiment
The expanded type desk is shown among Fig. 1 and by 10 and represents according to the preferred embodiment of the present invention.Desk 10 has support member 12, and expanded type table top component (will be illustrated below) is supported on the ground.The table top component has central longitudinal axis Y-Y, and comprises the top part 14 of desk, circular intermediate member 16 and circular bottom parts 18, and wherein the top part 14 of desk is made up of a plurality of top branches (will be illustrated below).
At first with reference to bottom parts 18, it has three groups of grooves.First group of groove is three grooves 20 that are separated from each other, and these three grooves 20 are that the point that passes bottom parts 18 places with axis Y-Y is three sections circular arcs of the same circle of the center of curvature.Three grooves 20 are arranged around this center of curvature equal angles.See that from above the bottom of each groove 20 is inclined upwardly in the counterclockwise direction with respect to bottom parts 18.
Second group of groove is three groove 22a and three groove 22b.Three groove 22a are the some equal angles layouts that are separated from each other and pass bottom parts 18 places around axis Y-Y.The bottom of each groove 22a is that part is smooth, part tilts.Three groove 22b also are the some equal angles layouts that is separated from each other and passes bottom parts 18 places around axis Y-Y.The bottom of each groove 22b is that part is smooth, part tilts with respect to bottom parts 18.
The 3rd group of groove is six grooves that separate 24 of non-circular shape.As can be seen, some groove 24 passes a groove 22a and a groove 22b, and 24 of some grooves only pass a groove 22a.The bottom of groove 24 is smooth with respect to bottom parts 18 basically.
About intermediate member 16 (also being shown among Fig. 3), it comprises circular housing 25 and is fixed to six of this housing 25 radially bars 26 arranged of equal angles.Engaging on each bar 26 has sliding bar 28, and this sliding bar 28 can slide along the length of this bar 26 with respect to the bar 26 that engages separately with it.As can be seen, bar 26 has been divided into six five equilibriums with intermediate member 16.Three side levers 30 interior alternately are fixed in described six five equilibriums three.Each interior side lever 30 has hole 32.In addition, each in six five equilibriums of intermediate member 16 is provided with two and has different length and be fixed to parallel bar 34,36 on two adjacent bars 26.Each bar 34,36 is equipped with a pair of pivotal part 38.
Turn to the top part 14 of desk now, it also is shown among Fig. 2, comprises three class tables tops branch, i.e. six fan-shaped branches 40, six roughly tetragonal collapsible branches 42 and circular branches 44.As shown in Figure 2, three supporting legs 46 are fixed to the lower surface of circular branch 44, and arrange around the longitudinal axis Y-Y equal angles.The end of each supporting leg 46 is rotatably mounted with roller 48.During assembling, each supporting leg 46 is arranged in the hole 32 on each interior side lever 30 of intermediate member 16, to be engaged in the groove separately 20 on the bottom parts 18, to make and is rotated and move along the groove 20 that engages separately with it by each supporting leg 46 entrained rollers 48.
Because be inclined upwardly in the counterclockwise direction when the bottom of each groove 20 is seen from above, so when middle parts 16 rotate when seeing from above in the counterclockwise direction with respect to bottom parts 18, will cause supporting leg 46 to rotate with respect to axis Y-Y in the same direction.During the relative motion that this side up, circular branch 44 is in axis Y-Y rotation at supporting leg 46 (and roller 48) and groove 20, also can be on the direction of Y-Y that parallels to the axis from bottom parts 18 rise (promptly away from).
About six roughly tetragonal collapsible branches 42 (being shown among Fig. 2), each branch 42 comprises outer section 52 and the inner segment 54 that can be pivoted relative to each other each other.Supporting leg 50 extends downwards from each inner segment 54 of collapsible branch 42.Each supporting leg 50 is rotatably mounted with roller 56.Each tetragonal collapsible branch 42 by with six five equilibriums of intermediate member 16 in each on four pivotal parts, the 38 fixing intermediate members 16 that are engaged in.During assembling, each supporting leg 50 is contained among separately groove 22a, the 22b, thereby roller 56 can be moved along groove 22a, 22b.
When middle parts 16 rotate when seeing from above in the counterclockwise direction with respect to bottom parts 18, will drive collapsible branch 42 and rotate accordingly in the same direction around axis Y-Y with respect to bottom parts 18.In the rotational travel of beginning, as more clearly illustrating in Figure 11, when pairing part 60 is smooth because the roller 56 in the bottom of groove 22a, 22b travels, branch 42 will only rotate around axis Y-Y.Yet, because the ensuing part 62 in the bottom of groove 22a, 22b is acclivitous with respect to bottom parts 18, when the roller 56 of supporting leg 50 when these sloping portions 62 move, each inner segment 54 (and having folded into each above the inner segment 54 outer section 52 now) will move up and lift away from from middle parts 16 and bottom parts 18.By this structure, when middle parts 16 rotate with respect to bottom parts 18, quadrangle branch 42 will move away intermediate member 16, and move radially towards axis Y-Y owing to the action of pivotal part 38, and motion mode will be illustrated below.
With reference to Figure 12, on the basal surface 64 of each fan-shaped branch 40, be fixed with one section timber (wood) 66 in addition, this timber 66 by fixing with a sliding bar 28 and from these sliding bar 28 upwardly extending extensions 68 and with these sliding bar 28 fixed engagement.Another extension 70 that is fixed on the sliding bar 28 extends downwards from this sliding bar 28, and is contained in the groove 24 with relative slip.Therefore, each fan-shaped branch 40 engages with separately groove 24 indirectly by the structure of corresponding bar 26 and sliding bar 28, so that slip relatively.
The expanded type table top component of expanded type desk 10 is shown among Fig. 4 with non-extended mode, and wherein six fan-shaped table top branches 40 are engaged with each other with continuous, the smooth circular table of common formation top.Every other table top branch, promptly quadrangle branch 42 and circular branch 44 all are accommodated in the space below the fan-shaped branch 40 and are positioned at intermediate member 16.When middle parts 16 with respect to bottom parts 18 when seeing from above in the counterclockwise direction (in the direction shown in the arrow A) go up when rotating around axis Y-Y, because engaging between each fan-shaped table top branch 40 and separately the groove 24 (one of them groove 24 is shown among Fig. 5), guiding based on groove 24, fan-shaped table top branch 40 will be along the path that is parallel to groove 24 rotates and leaves axis Y-Y around axis Y-Y with respect to bottom parts 18 and radially outward moves to outer fix, shown in the arrow B among Fig. 5.
As shown in Figure 6, during intermediate member 16 rotated with respect to bottom parts 18,42 beginnings of quadrangle table top branch were rotated around longitudinal axis Y-Y with respect to bottom parts 18.As mentioned above, quadrangle branch 42 moves subsequently and leaves bottom parts 18, and because the action of pivotal part 38 and diametrically opposedly move in axis Y-Y and towards axis Y-Y.
In addition, as mentioned above, during intermediate member 16 rotates with respect to bottom parts 18, the circular table top branch 44 of central authorities is also around axis Y-Y rotation, and on the direction of Y-Y that parallels to the axis from bottom parts 18 rise (promptly away from), upper surface coplane up to its upper surface and fan-shaped branch 40, as shown in Figure 7.
When the table top component was in this state, as shown in Figure 8, separately outer section 52 of each quadrangle table top branch 42 was manually outwards launched around the one or more hinges that are installed between outer section 52 and the inner segment 54 with respect to inner segment 54 separately.
As shown in Figure 9, the inward flange towards circular branch 44 of each in six quadrangle branches 42 is circular arc.Then, intermediate member 16 turns round slightly (promptly according to the direction shown in the arrow C among Fig. 9, when seeing clockwise direction) from above, fan-shaped table top branch 40 and quadrangle table top branch 42 are closely cooperated each other, so that and circular table top branch 44 forms continuous plane table top together, area when its area is in non-extended mode shown in Figure 4 greater than expanded type table top component has only the fan-shaped table top branch 40 common table tops that form in this non-extended mode.It can also be seen that, when desk 10 is in extended mode shown in Figure 10, the whole excircle of the common adjacent circular of the inward flange of quadrangle branch 42 branch 44.
For expanded type desk 10 being turned back to non-extended mode shown in Figure 4, only need oppositely to carry out above-mentioned steps.Particularly, intermediate member 16 is rotated in the counterclockwise direction to unclamp the cooperation between each top branch 40,42,44 with respect to bottom parts 18.On outer section 52 inner segment 54 that folds into separately with quadrangle branch 42.Then, intermediate member 16 is rotated in the clockwise direction with respect to bottom parts 18, circular branch 44 and quadrangle branch 42 are turned back in the space of intermediate member 16, and make fan-shaped branch 40 turn back to inner side, be engaged with each other to form less table top, as shown in Figure 4 in the fan-shaped branch 40 of this inner side.
In order to prevent that undesirable or unexpected relative motion takes place between intermediate member 16 and the bottom parts 18, locking pin 72 wears the hole 74 of bottom parts 18, moves on the direction shown in the four-headed arrow D-D with respect to bottom parts 18.A pin end of 72 can be contained in the groove 76 of housing 25 of intermediate member 16, between intermediate member 16 and the bottom parts 18 relative motion takes place so that prevent when the table top component is in extended mode.Can form second groove (not shown) in the another location of the housing 25 of intermediate member 16 and receive pin 72, be used for when the table top component is in non-extended mode, preventing between intermediate member 16 and the bottom parts 18 relative motion to take place.After one end of pin 72 withdraws from from groove 76, allow that intermediate member 16 rotates with respect to bottom parts 18, thereby allow that desk 10 moves between extended mode and non-extended mode.
Figure 14 to Figure 17 has represented and circular engagement step of pushing up between the branch 44 of central authorities in roughly tetragonal the top branch 42 in more detail.Figure 14 represents that quadrangle table top branch 42 is positioned at its lower position and folded state.As can be seen, the inward flange 80 of quadrangle branch 42 has fin 82, and the size of this fin 82 and structure are suitable for being received in the groove 84 on the outer peripheral edges of circular branch 44.It can also be seen that the inner segment 54 of quadrangle table top branch 42 and outer section 52 can be capable of pivoting relative to each other around one or more hinge 86.
As previously mentioned, 50 each entrained roller 56 edge groove 22a, the 22b separately of supporting leg separately by each quadrangle table top branch 42 advance.When roller 56 advances to the sloping portion 62 of groove 22a, 22b, roller 56 will move away from bottom parts 18, thereby make quadrangle branch 42 away from bottom parts 18 motions, and be guided by the motion of hinge 38, as shown in figure 15.As can be seen, between this moving period, folding quadrangle branch 42 also radially pivots towards the circular table top branch 44 and the axis Y-Y of central authorities.
When intermediate member 16 rotated end with respect to bottom parts 18, folding quadrangle branch 42 was lifted to position shown in Figure 16, was higher than the upper surface of the circular table top branch 44 of central authorities a little at the upper surface of this position inner segment 54.Then, be accommodated on the housing 25 up to outer section 52 by will outer section 52 outwards pivoting from the inner segment 54, thereby quadrangle branch 42 is launched, as shown in figure 17.Then, intermediate member 16 turns round (as mentioned above) a little, and the groove 84 on fin 82 and the center subsections 44 on the inner segment 54 is connected releasedly in the mode that engages.
Should be appreciated that above only be used for the explanation can implement embodiments of the invention, under the prerequisite that does not depart from spirit of the present invention, can make various modifications and/or replacement to it.It is also understood that described in one embodiment each feature of the present invention also can provide separately or provide with any suitable sub-portfolio.
