Abstract

The invention relates to a method for writing with a chalk clamping device by persons with disabled fingers and a structure of the chalk clamping device. The using method includes the steps of enabling the fingers (A) to be inserted into the thick hole end of the clamping device (1) , abutting against one end of a chalk (B) penetrated from the thin hole end in the thick hole end with the fingers (A), enabling the other end of the chalk (B) to be exposed out of the thin hole end, respectively tightening the exposed parts of the fingers (A) and the exposed part of the chalk (B) with the portions, extending out of the clamping device (1), of a rubber elastic thick sleeve (3) and a rubber elastic thin sleeve (2), and the part, exposed out of the rubber elastic thin sleeve (2), of the chalk (B) can be driven by the fingers (A) to complete the writing process on a blackboard. The structural mode is that the interior of the clamping device (1) is formed by a small caliber thin hole section and a large caliber thick hole section which are arranged in a front-and-back mode in a penetrated mode; in addition, the thin hole section and the thick hole section are sleeved with the rubber elastic thin sleeve (2) and the rubber elastic thick sleeve (3) respectively. The method and the structure are particularly suitable for teachers with the disabled fingers.

Description

Refer to that residual person utilizes method that chalk clamping device writes and the structure of chalk clamping device thereof

Technical field

The present invention relates to refer to that residual person utilizes method that chalk clamping device writes and the structure of chalk clamping device thereof

Background technology

At present, that on market, sells can continue the chalk clamping device using for short chalk, the cooperation that all needs to comprise two hands of thumb just can complete the write work of short chalk on blackboard that drives the other end, yet, be not suitable for losing disabled person's use of thumb, for above-mentioned disabled person, feel that it's rather a pity.

Summary of the invention

The present invention's object: the problem that is exactly above-mentioned in order to solve " it's rather a pity ".

For realizing the object of the invention, adopt following technology:

The present invention utilizes the method for chalk clamping device: allow finger pierce into the gross porosity end of clamping device and within it portion by finger, prop up one, the chalk that pierces into from pore end, and allow the other end of this chalk expose pore end, simultaneously, allow again and stretch out the thick sleeve pipe of rubber elasticity of clamping device and the portion of the thin sleeve pipe of rubber elasticity tie tight the respectively finger exposing and the chalk exposing, and allow the chalk that exposes the thin sleeve pipe of rubber elasticity under the driving of finger, on blackboard, complete the process of writing.

---if described finger is less than gross porosity end 1.6 centimeter inner diameter in clamping device, can as filling behave, make up by the outer cloth that twines of this finger.

Chalk clamping device of the present invention structurally comprises: clamping device, and, the inside of clamping device by tandem and the small-bore thin hole section running through and the thick hole section of heavy caliber form, and the pore section of clamping device and coarse pore section respectively overcoat have the thin sleeve pipe of rubber elasticity and the thick sleeve pipe of rubber elasticity;

The thin sleeve pipe of described rubber elasticity and the thick sleeve pipe of rubber elasticity stretch out respectively pore section and the coarse pore section of clamping device.

The scheme of producing of chalk clamping device of the present invention, it is drawn materials and sees the explanation in " specific embodiment " paragraph with the concrete size of key.

Feature of the present invention:

Owing to implementing respectively rigid location at clamping device two ends, chalk and finger (by clamp structure, have been realized), increased again the behave of tying tight in the auxiliary soft location of two different size caoutchouc elasticity sleeve pipe, to prevent that chalk and finger are easy to get loose or displacement writing when stressed after simple above-mentioned rigid location.---for example: two has the chalk of thickness in above-mentioned rigid location, to be easy to stressed getting loose or displacement, this just makes to refer to residual person, especially can be by singly referring to that utilizing chalk clamping device one of the present invention to bring in drives the chalk of the other end to write easily the condition created on blackboard for losing the handicapped person of thumb.

Accompanying drawing explanation

Fig. 1 has illustrated the structural principle of the embodiment of the present invention.

1, clamping device; 2, the thin sleeve pipe of caoutchouc elasticity; 3, the thick sleeve pipe of caoutchouc elasticity; A, finger; B, chalk.

The specific embodiment

Shown in Fig. 1, the present embodiment can adopt following specific design scheme:

Can be by the disposable machine-shaping clamp structure 1 of plastics, its concrete size is respectively: 10 centimetres of overall lengths (or 7 centimetres), the thick hole formation of the thin hole that there are 4 centimetres of internal diameter 1.0 centimeter length or long 2 centimetres (the short chalk B of adapted time) in inside and 6 centimetres of internal diameter 1.6 centimeter length or long 5 centimetres (the short chalk B of adapted time), the hole wall of clamp structure 1 is thick is greater than 1.2 centimetres

Get on the outer wall at the outer thin hole position that is enclosed within 1.0 centimetres of internal diameters of the thin sleeve pipe 2 of the caoutchouc elasticity of 0.15 centimetre of internal diameter 0.6 cm thick and allow it grow at least 1 centimetre of this thin hole end; Get on the outer wall at the outer thick hole position that is enclosed within 1.6 centimetres of internal diameters of the thick sleeve pipe 3 of the caoutchouc elasticity of 0.15 centimetre of internal diameter 1.2 cm thick and allow it grow at least 1 centimetre of this thick hole end.

Using method of the present invention and overall structure general introduction, the relevant portion explanation of concrete visible " summary of the invention " paragraph.

Claims

1. A method for the handicapped to use the chalk clamping device to drive chalk to write: Let the finger (A) penetrate the thick hole end of the clamping device (1) and use the finger (A) to resist the end of the small hole inside it.
