When making extension 20 from the configuration of pulling out shown in Figure 1 when entering retracted position, the operator scheme of said apparatus is as follows.Shown in Figure 1 pulling out in the configuration,

cross section

16 and 26 adjoins each other, and the head 37 of first keeper 35 is contained in first slit 120, and---because the base portion 38 of this keeper 35 is positioned at head 132 belows---keeps this second keeper 130 to be in the position of raising.The 3rd keeper 140 is in such position then, that is, make its head 142 be arranged in the lower surface 119 of wing plate 116 corresponding to the aperture of first slit 120.

At this moment, for the extension 20 of withdrawing, the user must catch the free end of extension 20 and raise this free end with his/her hand, promptly, by utilize the column bolt 34 that is associated with extension 20 and with wing plate 116 that fixing desktop 10 is associated between be connected, rotate counterclockwise described free end to center on horizontal axis X.Like this, the head 37 of first keeper 35 leaves second keeper 130, thereby moves down so that the whole thickness by extension and skid off the lower surface 119 of wing plate 116.Move when will finish described, head 37 collisions of keeper 35 are on the angled head 142 of the 3rd keeper 140, and described like this 3rd keeper is pushed to fixedly that desktop 10-sees Fig. 2.

When described mobile end, the head 142 of the 3rd keeper 140 finally abuts against on the undercut portions 39 on the head 37 that is arranged at first keeper 35, thereby prevents that definitely extension 20 can be rotated further-see Fig. 3 around horizontal axis.

When arriving this position, the user promotes extension 20 so that it rotates 180 ° with respect to fixing desktop 10 around axis Z, this is that it is constant to keep keeper 35,130,140 layout and the layout of column bolt 34 on wing plate 116 relative to each other simultaneously because the lining 110 of hinge 100 can rotate with respect to

dish

150 and 160 with wing plate 116.When this rotate to finish, extension 20 was in retracted configuration,, was positioned at fixedly desktop 10 belows-see Fig. 4 that is.

On the contrary, in the time must enlarging the available desktop of desk, promptly, must pull out and make it to enter when pulling out configuration from the retracted position (configuration shown in Figure 4) that is positioned at fixing desktop below extension 20, the user must at first utilize the lining 110 of hinge 100 make extension 20 along the direction opposite and opposite order around axis Z with said process with respect to 180 ° of fixing desktop 10 rotations, it is constant to keep keeper 35,130,140 layout and the layout of column bolt 34 on wing plate 116 relative to each other simultaneously.When this rotates end, extension 20 and hinge 100 will be in configuration shown in Figure 3.

For being entered, extension 20 pulls out configuration, the user must catch the free end of extension 20 and further raise this free end this moment with his/her hand, promptly, this free end is rotated counterclockwise around horizontal axis X, up to the upper surface 118 of the lower edge contact wing plate 116 in the cross section 26 of this extension 20 on column bolt 34.This rotation can realize with cooperating of wing plate 116 by column bolt 34, and the head 37 of first keeper 35 and the head 142 of the 3rd keeper 140 are disengaged.Can carry out this disengaging because the moving of the piston 140 that the effect of biasing spring 144 causes makes, and make second keeper 130 can be then to lower slider in the narrower slit 122 of connecting hole 126 and wing plate 116.When the head 132 of this second keeper 130 was arranged in the annex 124 of bigger slit 120 of wing plate 116 fully, described sliding motion finished-sees Fig. 5.

At last, the user reduces extension 20, that is, this extension is clockwise rotated around horizontal axis X on column bolt 34, and this causes the head 37 of first keeper 35 Fig. 6 that moves up-see in the slit 120 of wing plate 116.Finally abut against when the cross section 26 of extension 20 on the cross section 16 of fixing desktop, and when the base portion 38 of first keeper 35 is positioned at head 132 belows once more, the descending motion of extension 20 stops certainly, thereby second keeper 130 is remained on the position of raising-see once more Fig. 1.First keeper 35 interacts with second keeper 130 by this way just, so can keep extension 20 effectively, that is, withdraw by preventing this extension accident under the effect of the power that along continuous straight runs is applied thereto, thereby make this extension stable and fixing in pulling out configuration.

Although the explanation of front relates to the preferred embodiments of the present invention, it should be understood that, in the claims restricted portion, there are many other embodiment of the present invention and modification.Especially should be understood that described desk can comprise the extension of any requirement, and not only have only an extension as mentioned above, but when the fixing shape of desktop be square or during rectangle, the quantity of extension is not more than 4 usually.
