Abstract

The utility model relates to an extendable table, which comprises a table surface, a symmetric horizontal rod positioned under the table surface, an extension board coordinated between the horizontal rods, an upper and a lower slide rail positioned at the internal side of each horizontal rod, a slide wheel that is positioned at the lateral side of the extension board and coordinates with the slide rail. The upper slide rails is composed of three parts: an upper and a lower horizontal part and an oblique part that connects the upper and lower parts; the lower slide rail is also composed of three parts: an upper and a lower horizontal part and an oblique part that connects the upper and lower parts; The upper and lower horizontal parts of the upper slide rail is higher than that of the lower slide rail. The utility model, with the adoption of coordinated slide rail and slide wheel, as well as special design for slide rail, is able to realize the extension of a flexible board without the use of pull rod, spring and other components, thus realizing the change of table surface. The utility model has the advantages of simple structure, convenient application and low production cost.

Description

Stretchable desk

Technical field:

The utility model relates to the desk technical field, and particularly a kind of desktop can become big stretchable desk.

Background technology:

Along with growth in the living standard, people are also more and more exquisite to daily household quality, particularly choosing of furniture, especially desk.General desk, its style, size are all fixed, the consumer can not oneself change, but sometimes the time, when for example between room and room, moving desk, the bigger desk of mobile desktop is just very inconvenient, or becomes for a long time as the user quickly, and the less desk of desktop does not satisfy needs again.At these situations, there has been folding table to emerge, it mainly is at each limit of desk hinged portable plate of loose-leaf, and portable plate is opened, and can form bigger desktop, but, folding table is general only to be fit to wooden, is not suitable for the glass table.Certainly, now drawing desk is arranged also, generally adopted slide rail, cooperate and a series ofly realize stretching as accessories such as pull bar, springs, this structure is widely applicable, but its main shortcoming is complex structure, production cost height, and when being applied on the glass table, use very inconvenient.

The utility model content:

The purpose of this utility model is to provide a kind of desktop can become big stretchable desk at the deficiencies in the prior art.

For achieving the above object, the utility model adopts following technical scheme: it includes desktop, the desktop below is fixed with the cross bar of symmetry, be combined with drawing plate between the cross bar, each cross bar inboard all offers upper and lower two slide rails, the drawing plate side is equipped with the movable pulley that cooperates with slide rail, last slide rail is made up of three parts: upper and lower horizontal component, with the sloping portion that upper and lower horizontal component connects, glidepath is made up of three parts: upper and lower horizontal component, with the sloping portion of upper and lower horizontal component connection.

The end of the last horizontal component of described glidepath forms groove.

The described upper and lower horizontal component of going up slide rail is respectively than the upper and lower horizontal component height of glidepath.

The mode that the utility model directly adopts slide rail to cooperate with pulley, and adopted special slide rail design, need not parts such as pull bar, spring and can realize the stretching of portable plate, and then reach the purpose that desktop changes.The utlity model has advantages such as simple in structure, easy to use, that production cost is lower.

The specific embodiment:

See accompanying drawing 1-4, the utility model includes desktop 10, and the shape of desktop 10 is changeless, and the desktop area is also fixed.Desktop 10 belows are fixed with the cross bar 20 of symmetry, are combined with drawing plate 30 between the cross bar 20, also are fixed with active desktop 40 on the drawing plate 30 of the present utility model.Each cross bar 20 inboard all offers upper and lower two slide rails 22,24, drawing plate 30 sides are equipped with the movable pulley that cooperates with slide rail, movable pulley can move in slide rail, advancing slip driving wheel 50 places in the slide rail 22, back movable pulley 60 places in the glidepath 24, by pulling drawing plate 30, thus the change of realization desktop size.

See Fig. 5, wherein going up slide rail 22 is made up of three parts: upper and lower horizontal component 222,224, with the sloping portion 226 that upper and lower horizontal component connects, glidepath 24 is made up of three parts: upper and lower horizontal component 242,244, with the sloping portion 246 of upper and lower horizontal component connection.

Can not collide with desktop 10 when stretching for the active desktop 40 that drawing plate 30 is supported produces friction, and the upper and lower horizontal component 222,224 of going up slide rail 22 of the present utility model is respectively than upper and lower horizontal component 242,244 height of glidepath 24.In addition, between horizontal component 242 on the glidepath 24 and sloping portion 246, also add vertical portion 250.

The end of the last horizontal component 242 of described glidepath 24 forms groove 248.

Fig. 6-10 is that active desktop 40 is from folding to the process schematic diagram that launches.

As Fig. 6, during contraction state, active desktop 40 folds below desktop 10;

As Fig. 7, during stretching, drawing plate 30 is drawn outside twice horizontal components 224,244 of upper and lower slide rail 22,24, make the pulley on the drawing plate 30 be positioned at sloping portion and horizontal component intersection;

As Fig. 8, continuation pulls outward drawing plate 30, it will rise along two sloping portions 226,246 of upper and lower slide rail 22,24, when current movable pulley 50 is in the left of horizontal component 222 of slide rail 22, back movable pulley 60 is in 250 lower ends, vertical portion of glidepath 24, at this moment, because the height difference of forward and backward

movable pulley

50,60, make drawing plate 30 tilt the below laterally, and then make between active desktop 40 and the desktop 10 and can not produce collision;

As Fig. 9, along lifting to horizontal level on the vertical portion 250, make back movable pulley 60 be positioned at the left of horizontal component 242 drawing plate 30;

As Figure 10, will push away before the drawing plate 30, slided in the back and 60 take turns to fall in the groove 248 and maintain static, and advancing slip driving wheel 50 is in horizontal component 222 right-hand of slide rail 22, thereby realize active desktop 40 and desktop 10 amalgamation evenly together.

When folding, can only need earlier drawing plate 30 is stretched backward, make back movable pulley 60 break away from grooves 248, and then propelling gets final product to the front lower place until the left that is in horizontal component 242 by the opposite procedure operation of above-mentioned expansion action.

Same desk will realize that two ends all can extended desktop, can one group of relative cross bar 20 all be set the two ends below desktop, also can on same cross bar 20, offer being much of slide rail 22 and glidepath 24, cooperate corresponding drawing plate 30 and active desktop 40 again.

The utlity model has the advantages such as simple in structure, easy to use, that production cost is lower.
