Abstract
The present invention relates to a height adjustment tool of the book, the support base for legs.
To this end, the present invention is a book installed between the support leg and the frame, the height adjustment port for adjusting the height of the support for the leg is composed of an unlocking portion coupled to the support leg and a rod coupled to the lower portion of the frame, the unlocking portion The divided front body and the rear body are welded, the front body has a first slide groove is formed on both sides of the first insertion groove, the rear body is formed with a second slide groove on both sides of the second insertion groove The rod is inserted into an insertion groove in which the first insertion groove and the second insertion groove are butted, and an unlocking bar having an unlocking protrusion is inserted into the slide groove in which the first slide groove and the second slide groove are butted. A guide groove is formed in the front body corresponding to the unlocking protrusion to receive a spring elasticity in the guide groove, and the rod In the lower part of the frame is welded to the part, the pushing piece is welded to the lower part, a plurality of engaging grooves are formed between the frame and the pushing piece, the height adjusting opening of the support leg for the bench, the second slide Magnetics are inserted into upper and lower portions of the groove, respectively, and the unlocking protrusions are formed to protrude in a mountain shape toward the front body, and the pushing pieces are formed in plural numbers spaced apart from the lower part of the rod by a predetermined interval. It is done.
Description
The present invention relates to a height adjusting device for a book and a support leg, and in particular, a rod of a height adjusting device installed between the support leg and a frame is simultaneously drawn out by lifting a top plate or a seat of a table and a hand from a top plate or a seat. At the same time withdraw the rod is to be fixed by the adjustment.
In general, classrooms in elementary and secondary schools are equipped with desks and benches that can be used for reading and writing.
The desk is equipped with a support leg provided by bending pipes, a top plate coupled to the top of the support leg, a storage box for storing books, notes and writing instruments at the bottom of the top plate, and a bag or shoe pocket on one side of the storage box. It consists of a hook.
The stool is composed of the seat plate and the back plate coupled to the frame coupled to the upper part of the supporting leg so that the student or user can easily sit.
These books and stools are manufactured in three different sizes based on the average height of each grade. Students with average heights did not have any inconvenience in using books and stools. There were many inconveniences in using books and stools.
In order to solve this problem, the upper column having a plurality of positioning holes is coupled to the lower part of the book and the stool, the upper column is inserted into the lower column formed with the through hole, and the fixing pin is located in the through hole and the positioning. The height is adjusted to fit in the hole.
However, it was difficult to do it alone in the process of adjusting the height of the book and the stool by inserting the fixing pin after matching the positioning hole and the through hole, and the book and the stool were inclined when the inserted pin was pulled out in the reverse direction. there was.
The present invention allows the user to easily adjust the height of the book, the stool alone, and through this makes the height of the book, the stool to suit their physical conditions, if you take a lesson or study for a long time, less fatigue It is to improve the efficiency of.
The present invention is the height adjustment sphere (A) for adjusting the height of the book, the support for the bench installed between the
The present invention is to lift the upper plate of the desk or the seat plate of the desk and at the same time the rod of the height adjustment device installed between the support leg and the frame is drawn out, and at the same time the withdrawal of the rod from the top plate or seat plate is fixed by the control By doing so, it is possible to obtain the effect of easily adjusting the height of books and stools alone.
In addition, the height of the books and stool to suit their physical conditions, if you sit for a long time or study, so that less fatigue to improve the efficiency of the class.
An embodiment of the present invention will be described with reference to the accompanying drawings.
