Abstract

The utility model discloses a chair comprising a rear left leg and a rear right leg, wherein a rolling device is arranged at the bottom parts of the rear left leg and the rear right leg respectively; and each rolling device comprises a bracket, a rotating shaft and a roller, wherein the bracket is arranged at the lower end of the rear leg and provided with a round hole, the rotating shaft is connected with the bracket through the round hole, and the roller is arranged on the rotating shaft. A spice box is arranged on the back of the chair, and each side surface of the back of the chair is provided with a hook. The using method of the chair is as follows: when the chair is moved, two front legs are lifted away from ground, and then only static friction instead of sliding friction exists between the rollers and the ground, therefore, labor is saved and friction noise is avoided. When the chair is not moved, the contact of the two front legs with the ground enhances the friction force between the chair and the ground, therefore, the chair can not move or slide easily even though the rollers are arranged at the rear end of the chair. The chair has the advantages of being simple in structure, convenient to use and the like.

Description

A kind of chair

Technical field

The utility model relates to a kind of chair.

Background technology

Be placed in the chair in meeting room or dining room, obsolete the time, in order to reduce floor space, often to be moved conference table into or dining table below.Have only when in use, just they are moved out below conference table or dining table.When moving chair, the somebody is in order to save trouble, only by the chair back of the body is applied horizontal force, directly chair is hauled out or pushed in, owing to produce sliding friction between chair legs and the ground, thereby can produce grating, will feel very bored for other meetings or the personnel of having dinner; In order not produce annoying grating, the somebody can remove chair earlier, makes the chair legs built on stilts, and chair is moved to suitable place, and then puts down lightly, do like this, though there has not been grating, effort, very inconvenient.In addition, during meeting, people usually can have a handbag, if handbag is placed on the desk very not attractive in appearance, are placed on untotally again on the ground, have brought inconvenience to people.

Summary of the invention

At above-mentioned prior art, the utility model provide a kind of simple in structure, easy to use, promptly do not have an effortless again chair of grating.

The utility model is achieved through the following technical solutions:

A kind of chair comprises left and right sides back leg, the chair back of the body, and wherein, back leg bottom in the left and right sides is equipped with tourelle, described tourelle comprises support, rotating shaft, roller, wherein, props up and is erected at the back leg lower end, support is provided with circular hole, and rotating shaft is connected with support by circular hole, and roller is located in the rotating shaft.

Described chair back is provided with spice box, and the chair dorsal surface is provided with hook.

Use: inclination chair during mobile chair, make two forelegs liftoff, because it is roller and ground have only the fricton-tight friction of static friction, therefore, laborsaving and do not have a grating.During not mobile chair,, increased the frictional force between chair and the ground, so though the chair rear end is a roller, chair can not be moved or slide easily yet owing to contact between two forelegs and the ground.Handbag can be hung on the hook, easily.Can place some volatile spices in the spice box, build an environment that fragrance is warm during meeting.

The utlity model has advantages such as simple in structure, easy to use.

Distance about support 4 between two vertical planes is smaller or equal to the length of rotating shaft 3, the length of two vertical planes is greater than the radius of roller 2 about support 4, on two vertical planes a symmetrical circular hole is being arranged respectively about support 4, the diameter of circular hole equals the diameter of section of rotating shaft 3, and circular hole is greater than the radius of roller 2 to the distance of back leg 1 bottom.The length of rotating shaft 3 is greater than the thickness of roller 2.During installation, roller 2 by bearing fixing behind the centre of rotating shaft 3, again rotating shaft 3 be fixed on support 4 about in the circular hole on two vertical planes.Two back legs 1 about chair are cut out identical length, make the length that cuts out equal to install the height of the support 4 of roller 2, the support 4 that installs roller 2 is fixed on the bottom of two back legs 1, make chair base surface 5 keep levels.

During use, catching the chair back of the body 7, is fulcrum with the contact point on roller 2 and ground, and the rear slight inclination along the chair back of the body 7 makes foreleg 6 built on stilts, and the chair of this moment only contacts with ground by roller 2, and chair is moved horizontally.

During meeting,, handbag can be hung on the hook 8, easily if there is the people to carry handbag.Can place some volatile spices in the spice box 9, build an environment that fragrance is warm during meeting.
