Abstract

A kind of method that thumb people with disability uses chalk-writing, has: chalk (B), it is characterized in that: chalk (C) and finger (A) are inserted respectively small-bore nose end and heavy caliber nose end (the implementing the packaged type location of rigid stress) of retaining sleeve (1), and prop up chalk (C) tail end by finger (A) and expose the length of retaining sleeve (1) to control chalk (C) leading portion, last will be arranged on retaining sleeve (1) outside again and stretch out spring-backed quill (3) cut-off respectively of retaining sleeve (1) two end portions and fasten in the way of tightly overlapping the outside (implement the elasticity of auxiliary tie tight position and stop it to be subjected to displacement) of outside and finger (A) of chalk (C), single finger (A) is allowed to drive chalk (C) to complete the process write by retaining sleeve (1) with this behave. its construction features is in that: retaining sleeve (1) is provided through built-in bushing pipe (2) and can embed the small-caliber end of chalk (B) and directly can embed the heavy caliber end of finger (A), further, retaining sleeve (1) is also outer is cased with being longer than the spring-backed quill (3) of this retaining sleeve (1).

Description

Thumb people with disability uses the method for chalk-writing and performs device

Technical field

The invention belongs to people with disability's articles for use technology, particularly related to a kind of thumb people with disability and used the method for chalk-writing and perform device technique.

Background technology

At present, the chalk clamping device sold on market, only can position the writing device (must flow through two fingers can drive chalk to write on blackboard) of short chalk, without single finger and chalk can be positioned in one mechanism simultaneously, and allow the device of single finger actuation chalk-writing, this, for losing the people with disability (in industrial injury Can Zhi person colony not very few) of thumb, feels that it's rather a pity.

Summary of the invention

The purpose of the present invention: the problem being contemplated to solve above-mentioned " it's rather a pity ".

For realizing the object of the invention, it is achieved by the following technical solutions:

The method of the present invention: chalk and finger are inserted respectively small-bore nose end and heavy caliber nose end (the packaged type location implementing rigid stress easily loosens) of retaining sleeve, and prop up chalk tail end control chalk leading portion by finger and expose the length of retaining sleeve, last again by be arranged on outside retaining sleeve and Shen go out the spring-backed quill part cut-off respectively at these retaining sleeve two ends fasten in the way of tightly overlapping chalk outside and finger outside (implement the elasticity of auxiliary tie tight location and stop it to be subjected to displacement), single finger is allowed to pass through the process that hard retaining sleeve drives chalk to write on blackboard with this behave.

The execution device of the present invention: retaining sleeve is provided through built-in bushing pipe and can embed the small-caliber end of chalk and directly can embed the heavy caliber end of finger, further, retaining sleeve is also outer is cased with being longer than the spring-backed quill (its two ends have more retaining sleeve 1 centimetre at least respectively) of this retaining sleeve. When being enclosed within retaining sleeve outside this spring-backed quill, it is possible to arrange in the way of naturally keeping flat, it is also possible to arrange in the way of longitudinal convolution is folded, and prepare when not using the present invention to be activated at any time in the way of this is arranged;

Described retaining sleeve is by bore less than 1.5 centimetres, and long 10 centimetres, the thick rustless metal material more than 0.2 millimeter makes;

Described bushing pipe is 1 centimetre by bore, the plastic production of long 3 centimetres, and, it is embedded in one end of retaining sleeve in the way of tight fit or gluing;

Described spring-backed quill is by bore less than 0.9 centimetre, and the thick high-tension rubber type of material more than 0.1 centimetre makes.

The feature of the present invention: position finger and chalk respectively in its rear and front end owing to the present invention can pass through hard retaining sleeve, two ends further through the spring-backed quill being enclosed within outward on retaining sleeve, tie tight respectively (soft location) above-mentioned rigid finger being positioned at these retaining sleeve two ends and chalk, easily releasable or displacement during to prevent chalk and finger from writing stress in simple above-mentioned rigid location. Such as: two has the chalk of thickness to be easiest to stress in above-mentioned rigid location to get loose or displacement. This just for writing, by the chalk of the single finger actuation other end of one end, the condition of creating on blackboard, is solution and refers to that the problem of residual person above-mentioned " it's rather a pity " creates condition.

Accompanying drawing explanation

Figure illustrates the structural principle of the embodiment of the present invention.

1, retaining sleeve (adopting rustless metal to produce); 2, bushing pipe (adopting plastics to produce); 3, spring-backed quill (adopting latex class or rubber type of material to produce); A, hands refer to; B, chalk clamping device; C, chalk.

Detailed description of the invention

Shown in accompanying drawing, the critical piece that the present embodiment includes has:

Retaining sleeve 1 be embedded in the bushing pipe 2 of this retaining sleeve 1 one end and be enclosed within outward on this retaining sleeve 1 and its length is more than the spring-backed quill 3 of this retaining sleeve 1, and become chalk clamping device B by this triplicity. Spring-backed quill 3 has more the part of this retaining sleeve 1 and the elastic force of its glue class can be utilized to assist retaining sleeve 1 two ends to position the single finger A of people with disability and the chalk C of the other end respectively in the way of tying tight.

Retaining sleeve 1 is under the premise guaranteeing its firm intensity, and its thickness should get over Bao Yuehao, it is therefore intended that: make the caliber size difference at its two ends the smaller the better. Making the spring-backed quill 3 on this retaining sleeve 1 of overcoat expose the part at two ends, when implementing the outside in the tight outside overlapping the chalk C that fastens and finger A, the size exerted oneself respectively is as far as possible close.

The internal diameter of bushing pipe 2 is 1 centimetre (the chalk C diameter according to national regulations), and external diameter is 1.5 centimetres, by tighter be embedded in retaining sleeve 1 one end in the way of the rwo is combined.

The material that spring-backed quill 3 adopts should have higher elastic force, and realizes allowing its two ends implement tight set respectively with this fastening requisite " auxiliary " function in outside of chalk C and finger A. Chalk C and finger A to guarantee retaining sleeve 1 two ends will not come off from the two ends of this retaining sleeve 1

If feeling, the diameter of finger A is less than normal, it may be considered that liner cloth heavy caliber end to aid in the retaining sleeve 1 of hard on finger A positions, and equally possible is tied tight by finger A under the auxiliary elastic force of additional spring-backed quill 3. Namely equally possible normally and easily allow finger A drive chalk C write on blackboard. Obviously, the spring-backed quill 3 adopting key in the present invention is necessary (indispensable).

If feeling, the diameter of finger A is bigger than normal, the chalk C being intended to write is partially short again, etc. factor, namely can refer to the structural principle of qualitative signal in accompanying drawing, reset the specification (relatively easy further instruction is omitted) constituting the retaining sleeve 1 of chalk clamping device B, bushing pipe 2 and spring-backed quill 3 as the case may be.

Thumb people with disability utilizes chalk clamping device B to use the chalk C method write, the relevant part expressed in visible above-mentioned " summary of the invention " paragraph, the concrete data of multiple keys for reference in the typical technology design that the present invention adopts also show the important technology data in above-mentioned " summary of the invention " paragraph about expressing.
