Description

The table of adjustable height/chair pin

The utility model relates to a kind of improvement structure of table and chair feet, specifically, is a kind of Height Adjustable table and chair feet.

General as employed student desk and chair on the school classroom, all same height in design in the past, that is to say, no matter how short user's height is how high or, the height of table, chair can not be adjusted, so the child receives an education the stage, because table, chair height and actual user's height can't adapt identical, thereby cause reading, writing posture incorrect, and then cause child's bone to send out the undesired of the region between the heart and the diaphragm, and the infringement of eyesight; Searching to the bottom, except the lamplight brightness problem, is exactly the use height problem of school desk's chair of maximum duration.

Therefore, manufacturer is one after another at the actual different requirements of using height of desk (chair), and design Desk capable for rising and falling miscellaneous, chair, such as the known patent creation case in Taiwan: announce No. 255137, No. the 241508th, bulletin, No. the 235445th, bulletin, No. the 232137th, bulletin, No. the 216503rd, bulletin, No. the 216499th, bulletin, No. the 205669th, bulletin, No. the 193836th, bulletin, No. the 160106th, bulletin, No. the 113554th, bulletin, No. the 106962nd, bulletin, No. the 103782nd, bulletin, No. the 60746th, bulletin or the like.

But the project organization that these known relevant creation demonstrate out is all very complicated, not only produces a large amount of cost burdens on manufacturing cost, simultaneously on processing is handled, also produce unnecessary cumbersome and inconvenience on the construction weight; Therefore, how designing simple structure, practicality is excellent, cost is low, production and processing is fast desk and chair, then is the target of still waiting to research and develop innovation.

The purpose of this utility model provides a kind of table/chair pin of adjustable height, so that to students in middle and primary schools, provides practicality excellent, uses the desk and chair of the appropriate adjustment that highly can coincide, and then protection student bone is sent out the region between the heart and the diaphragm and sight protection.

The utility model is to realize like this, it is that extension table/chair pin that each the table/chair script body that is possessed is more than the single-unit is improved, characteristics are: appointment one side at the internal segment table/chair pin of each the table/chair pin that is nested with assembly mutually is provided with the through hole of a setting internal diameter, and clip cap and its assembly of locating projection from inside to outside arranged; This clip cap system stretches out outside the through hole hole of internal segment table/chair pin from inside to outside, this clip cap end is the prominent ring of an external diameter greater than clip cap external diameter, clip cap front end then is a circular arc end face, be provided with an inserting hole in the rear end of clip cap, for the spring one end plant assembly that is installed in internal segment table/chair pin, and the whetstone of holding in addition of this spring places the inwall of internal segment table/chair pin; What the clip cap external diameter that wherein is located at internal segment table/chair pin was less than or equal to the through hole internal diameter of internal segment table/chair pin and acromere table/chair pin runs through the locating hole internal diameter; The external diameter system of the terminal prominent ring of clip cap is greater than the internal diameter of internal segment table/chair pin through hole in addition; And the clip cap is given prominence to the wall thickness of the outer length system of internal segment table/chair pin through hole greater than acromere table/chair pin; This acromere table/chair pin is the outside that is placed on internal segment table/chair pin, at the corresponding internal segment table of this acromere table/chair pin/chair pin one side of clip cap is set, and is provided with the locating hole of arranging more than that runs through.The spring shape system that is located at internal segment table/chair pin inside in the utility model is similar to R shape.

Described among the embodiment that progressive effect of the present utility model will provide in the back.

Accompanying drawing of the present utility model is simply described as follows:

Provide desk embodiment of the present utility model according to Fig. 1～Fig. 5 below, it is for the utility model is described, rather than is used for limiting claim scope of the present utility model.

See also Fig. 1, in the table/chair pin design of a kind of adjustable height of the present utility model, system includes desktop 1 and table pin 2, wherein four table pin are the above telescopic table pin of single-unit, appointment one side at the internal segment table pin 20 that is nested with is provided with a through hole 201 (shown in Figure 5), and the clip cap 3 (as shown in Figure 2) of outside projection one preseting length is set in internal segment table pin 20 inside at this place, these clip cap 3 rears are provided with the plant assembly (shown in Figure 5) of an inserting hole 31 for spring 4 one ends; And spring 4 side views that this outside whetstone pushes away clip cap 3 are approximate R shape, and one end system is inserted in clip cap 3, and other holds whetstone then to place the inwall place of a pin 20, to reach the effect that spring 4 outside whetstones push away the projection of clip cap.

And the acromere table pin 2 of confession internal segment table pin 20 sleeve assembly, side at corresponding internal segment table pin 20 outstanding clip caps 3, be provided with more than one equidistantly or the locating hole of equidistantly not arranging 21 that runs through is selected the clip usefulness for the clip cap 3 of internal segment table pin 20, be suitable for the adjustment of implementing table pin length (being the desk height).

Wherein this clip cap 3 as shown in Figure 5, clip cap 3 front ends are for setting circular arc end face 30, its external diameter system is less than or equal to through hole 201 internal diameters of internal segment table pin 20 and locating hole 21 internal diameters of acromere table pin 2, and be equipped with the prominent ring 32 of external diameter greater than clip cap 3 external diameters in the terminal periphery of clip cap 3, the external diameter of this prominent ring 32 is greater than through hole 201 internal diameters of internal segment table pin 20 and locating hole 21 internal diameters of acromere table pin 2; And clip cap 3 outstanding internal segment table pin 20 through holes 201 outer outstanding length are the wall thickness greater than acromere table pin 20; In addition, the design pitch system that terminal prominent ring 32 of clip cap and front end circular arc end face are 30 can be equal to or greater than the wall thickness of acromere table pin 2 locating holes 21 at least, the steadiness and the security of transposition to implement firm not pressurized, and the front end circular arc end face 30 of clip cap 3 is to stretch out outside locating hole 21 holes of acromere table pin 2.

In the use, primary and secondary students or any user, as long as be pressed into the length that is nested with that clip cap 3 could draw high or press down a

20,2 easily, and then height is read, write to the actual ideal of using of coincideing; And press when when adjusting, can help each other each other by and adjust, so no matter in operation, all have the utmost point on the structural design and simplify firmly and easy utilization benefit, it is low also to have a cost, structure produces relaxed industrial benefit; And the practical function that it possessed, industrial economy benefit, and structural design, be general known creation at present do not have identical possess have, the novel improved that really belongs to a novelty, practicality designs.
