Abstract

A method for handicapped persons to write with chalk, structurally: it includes a holding device (1) whose small hole can be put into chalk (B), and is characterized in that: the outer surface of the holding device (1) is A rubber elastic sleeve (2) longer than the clamping device (1) and thicker than 0.1 cm is pasted, and both ends of the rubber elastic sleeve (2) protrude from the clamping device (1) by at least 1 cm; The preparation method of the clamping device (1): use a 1.5 cm drill at one end of a hard pipe with an inner diameter of 1.0 cm, a length of 10 cm, and a thickness greater than 1.5 cm to drill a large hole with an inner diameter of 1.5 cm and a depth of 7 cm. ;Using method: Utilize the rubber elastic sleeve (2) on the clamping device (1) to grow out of the exposed parts at both ends of the clamping device (1), wrap them respectively and put them into the clamping device (1) by relying on elastic force to tighten them ) at both ends of the finger (A) and the exposed parts of the chalk (B), so that the exposed rubber of the chalk (B) can be easily driven by the finger (A) against the top of the chalk (B) inside the clamping device (1) Part of the elastic sleeve (2) completes the writing process.

Description

A way of referring to handicapped people writing with chalk

technical field

The invention relates to a method for referring disabled persons to write with chalk.

Background technique

At present, the chalk holding devices sold on the market for the continued use of short chalk all need the cooperation of two hands including the thumb to complete the writing work of driving the short chalk at the other end on the blackboard. It is quite a pity for the above-mentioned disabled people to use it for the disabled with the thumb.

Contents of the invention

Purpose of the present invention: just in order to solve above-mentioned " quite regrettable " problem.

For realizing the object of the present invention, adopt following technical scheme:

Structurally: it includes a holding device whose small hole can be put into chalk, and is characterized by:

The outer surface of the clamping device is pasted with a rubber elastic sleeve longer than the clamping device and thicker than 0.1 cm, and both ends of the rubber elastic sleeve protrude from the clamping device by at least 1 cm;

The manufacturing method of the clamping device: use a 1.5 cm drill bit at one end of a hard pipe with an inner diameter of 1.0 cm, a length of 10 cm, and an outer diameter greater than 1.5 cm to drill a large hole with an inner diameter of 1.5 cm and a depth of 7 cm;

How to use: Utilize the rubber elastic sleeves on the clamping device to grow out of the exposed parts at both ends of the clamping device, respectively cover and tighten the exposed parts of the fingers and chalk put into the two ends of the clamping device by elastic force, so that The part of the rubber elastic sleeve exposed by the chalk is conveniently driven to complete the writing process by pressing against the top of the chalk with a finger on the inside of the clamping device.

Features of the present invention:

Since the chalk and fingers are rigidly positioned at both ends of the clamping device (realized by the clamping device 1), the auxiliary soft positioning of the rubber elastic sleeve is added to tighten (to prevent loosening under force—for example: the thickness of the two ends is different) The chalk is most easily loosened or displaced by force), which creates conditions for the handicapped who lost their thumb to use the present invention to drive the other end of the chalk to write on the blackboard conveniently.

Description of drawings

Fig. 1 schematically shows the structural principle of the embodiment of the present invention.

detailed description

According to shown in Fig. 1, the processing of present embodiment is very simple: on existing plastic pipe, for example: get external diameter and be 2 centimetres, the plastic pipe (for example: water pipe) 10 centimeters of internal diameter 1.0 centimeters is long, in this pipe One end is reamed with the drill bit of 1.5 centimeters in diameter, and reaming degree of depth is 7 centimeters (formation: the long 7 centimetres of tube hole of internal diameter 1.5 centimeters), the main body of clamping device 1 of the present invention is promptly finished successfully, and its general situation of use is as follows:

The end with an inner diameter of 1.5 cm on the clamping device 1 is used to insert finger A, and the end with an inner diameter of 1 cm is used to insert chalk B (the diameter of chalk B is 1 cm according to the national standard), and any chalk A larger than 3.5 cm can be used The clamping device 1 of the present invention is positioned; then, the rubber elastic sleeve 2 is used to straighten and respectively tighten the finger A and the chalk B at both ends of the chalk clamping device 1 . ——At this point, the disabled thumb can use any finger A except the thumb to drive the chalk B to write on the blackboard conveniently through the clamping device 1 .

If the inner diameter of the thick hole end of the present invention is set to be 1.5 centimeters, if the diameter of the finger A is too small, for example, the diameter of the finger A is 1.1 centimeters, then several layers of cloth can be wrapped in the finger A, which can also be convenient. use the present invention.

If the finger A is too thick (diameter greater than 1.5 cm), the chalk B to be written is too short, and so on, you can reset the clamping device 1 with reference to the structural principle shown qualitatively in Figure 1 And the specifications and dimensions of the elastic sleeve 2 (quite easy—further description is omitted) can meet the needs.

Claims (1)

1. refer to that disabled person uses a method for chalk-writing,

Structurally:

It comprises that its little hole can put the clamping device (1) of chalk (B) into,

It is characterized in that:

The outer surface of clamping device (1) has been pasted again that length is greater than clamping device (1) and thickness and has been greater than 0.1 liThe caoutchouc elasticity sleeve pipe (2) of rice, and caoutchouc elasticity sleeve pipe (2) two ends all have more clamping device (1) at least 1Centimetre:

The preparation method of described clamping device (1): at 1.0 centimetres of internal diameters, long 10 centimetres, the large hand of external diameter1.5 centimetres of drill bit counterborings of hard tubing one end recycling of 1.5 centimetres become 1.5 centimetres of internal diameters, dark 7 centimetresLarge hole;

Using method:

Utilize the outer caoutchouc elasticity sleeve pipe (2) being enclosed within on clamping device (1) to grow exposing of clamping device (1) two endsPart, entangle respectively and rely on elastic force to tie tight to put into clamping device (1) two ends finger (A) and chalk (B) bothExposed parts so that prop up chalk (B) top with finger (A) in clamping device (1) inner side and drive easilyThe part that moving this chalk (B) exposes caoutchouc elasticity sleeve pipe (2) completes writing process.
