Abstract

A convenient eraser which is convenient to use, unease to loss, and can correct the wrong writing posture of children is characterized in that: an eraser is fixed by a belt which can be surrounded and worn on the middle joint of the user's middle finger. The top of the eraser is an inclined plane which is 45 degree (or less than 45 degree) relative to the vertical plane close to the figure. And the top of the inclined plane is not higher than the middle finger. The vertical length of the eraser is about two centimeters (about half centimeter from the bottom of the eraser to the paper surface is appropriate when the writing posture of children is correct). The belt of the eraser is worn on the middle joint of the user's middle finger to make the eraser on the back side of the finger in writing. The eraser is clamped by the lower of the forefinger and the upper of the middle finger (make the writing point of the pen away from the paper surface), and the thumb press the upper inclined plane of the eraser to erase the writing, thus the action of taking and putting is omitted in use, therefore improving the writing speed. The utility model can avoid that the eraser falls to the floor and lost as well as can prevent the wrong writing posture of children such as holding the pen too close, grapping the pen with full hand, therefore beneficial to students' health.

Description

The portable rubber

Affiliated technical field

The utility model relates to a kind of stationery that is used to wipe the pencil vestige, especially a kind of easy to use, rubber of being difficult for losing and helping to correct children's mistake writing posture.

Background technology

At present, known rubber has two kinds, first monolithic rubber, this kind rubber uses more flexible, be used to wipe the person's handwriting of various ways pencils such as common pencil, propelling pencil, lose on the ground but easily tumble, and each use all to " pick up " " putting down " and waste a lot of times (especially the underage child access times are more), influence writing speed; It two is the rubbers that are fixed on the pencil top, and this rubber is difficult for losing, but only is fit to be used in combination with the pencil of fix, and underaction, and mistake pencil all when at every turn using make things convenient for inadequately.

Summary of the invention

In order to overcome the deficiency of existing rubber, the utility model provides a kind of portable rubber, and this rubber is used to wipe the pencil person's handwriting, and is easy to use, be difficult for losing, and the writing posture that can help the student to correct a mistake.

The technical scheme in the invention for solving the technical problem is: rubber and a belt are fixed, belt is connected into annular be enclosed within the position of writing the close minor details of joint in the hand middle finger, rubber is positioned at the dorsal part of middle finger, the upper end of rubber does not exceed middle finger, the top of rubber is the inclined-plane that becomes (or being slightly less than) miter angle with the vertical plane of pressing close to middle finger, the vertical extension of rubber is (can divide big ting model) about two centimetres with correct writing posture and write that (finger tip is from the about one-inch of nib, penholder becomes miter angle with paper) the rubber lower end half centimetre away from paper is advisable be, during use, only need to clip pencil (make nib natural) gently with middle finger and forefinger from paper with what write hand, the while thumb is pinned the ramp of rubber and is embrocated, and recovers the original posture that holds a pen after using up again.If children's writing posture is incorrect, the lower end of rubber can be wiped paper and be pointed out its correction.

The beneficial effects of the utility model are, being fixed on the finger dorsal part does not influence normally and write, and can prevent that rubber from tumbling on the ground and lose; Saved " picking up " during use and action such as " put down ", improved writing speed (especially underage child is altered more); The utility model can also help the student to correct " writing near " wrong writing postures such as " full hand are grabbed "; Simple in structure, easy to make.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the profile organigram of an embodiment of the utility model.

Fig. 2 is the schematic diagram of the utility model user mode

Among Fig. 11, block rubber 2, belt 3, fixedly the collar 4, the rubber of rubber and belt ramp 5, with the dihedral angle of middle finger vertical plane 6, the inclined-plane pressed close to and the vertical plane formation of pressing close to middle finger

The specific embodiment

In Fig. 1, the collar (3) is fixed together rubber (1) and belt (2).The ramp of rubber (4) is equal to or slightly less than 45 degree with the dihedral angle (6) that vertical plane (5) forms, the upper end of rubber does not exceed the top of the collar (3), the width of belt (2) be no more than save in the middle finger 1/2, about two centimetres of the height of rubber, (pen becomes miter angle with paper with the position with correct writing posture with children, hold a pen the place from the about one-inch of nib) rubber lower end about half centimetre away from paper be, belt (2) can divide two statures up and down, connect by various forms of bracelets, can regulate its length according to the thickness of finger during connection, the also available resilient material of belt (2) is (as some cloth, rubber strip etc.) directly do and circularize.

The collar of rubber (3) can be made of plastics, and and belt (2) be one, the collar (3) inner surface closely contacts with block rubber (1), and with liquid glue they is bonded together.

The available foil of the cover of rubber (3) surrounds, belt (2) passes between the rubber (1) and the collar (3), and bonding or other modes make fixed to one anotherly with liquid glue, the collar (3) surface is pushed made it that distortion be arranged slightly then, contact closelyr, strengthen its fastness.

Claims

1, portable rubber, its major part are the block rubber that is used to wipe the pencil vestige, it is characterized in that: block common rubber and one can fix around the belt that is worn on the finger.

2 portable rubbers according to claim 1, it is characterized in that: the top of belt and common block rubber is fixed, block rubber top for becoming the inclined-plane of (or less than) miter angle with the vertical plane of pressing close to point dorsal part, the top, inclined-plane equal with top (the common face that pastes mutually with forefinger) of middle finger or be lower than middle finger above.
