Abstract

SUMMARY OF THE INVENTION: The means for fixing crayons has integral stops and pressure plates integrated with the hollow body and located inside it. The plates are integral with the body and have a pointed end to interact with the chalk. The distance between the opposing plates is smaller than the distance between the respective stops. The stops can be located directly under the pressure plates. 1 wp 4 ill.

Description

The invention relates to holders, mainly to holders for crayons, and allows you to maintain convenience in use.

The purpose of the invention is to simplify the design of the cradle holder and to maintain ease of use.

Fig. 1 schematically shows a crayon holder, where the means for fixing the chalk is made in the form of pointed engraving plates and stops; 2 schematically} o shows this crayon holder; Fig. 3 schematically shows a holder for chalk in which the stops are placed directly below the pressure plates; Fig. 4 schematically shows this holder with a crayon inserted into it.

The holder for crayons (Figs. 1 and 2) contains a tubular square or rectangular casing 1, in which integral pressure plates 2, as well as tori 3. are made integrally from the inside of the casing 1. They are designed to center the crayon 4. In Fig. .2 shows a holder with a shallow 4 in working position.

The means for fixing the chalk 4 can be made in the form of stops 3 placed directly under the pointed pressure plates 2 (Fig. 3). Fig. 4 shows the operating position of the chalk holder of this design when chalk 4 is inserted into it.

The holder for crayons works as follows,

When using the holder, crayon 4 (once during use - when refueling) is manually installed from the bottom with one end into a tubular, square or rectangular body 1, while the pointed pressure plates 2 are bent upwards (Fig. 2), since the distance between the sharp the ends of two opposite pointed pressure plates are smaller than the analogous (transverse) size of the body of the chalk 4.

Further advancing, the chalk body passes between the stops 3, since the distance between the ends of the two opposite stops 3 is equal to the size of the cross section of the chalk 4. As the tip of the chalk comes out

4 to the working position, the further advancement of the chalk 4 in the housing 1 is stopped and in this position the body of the chalk 4 is held by the pointed pressure plates 2 from being displaced and rotated in the housing 1. The holding of the body of the chalk 4 occurs mainly because the pressure bodies are angled at approximately 45 ° the plates 2, trying to return to their original position, are pressed against the body of the crayon 4 and inserted into it with pointed tips.

Figure 4 shows the operating position of the crayon holder when the stops 3 are located directly below the pointed pressure plates 2. Such a structural design allows the use of the released pressure plates 2 to keep the body of the chalk 4 from moving down. The operation of the chalk holder of this design is similar to that described above.

The offered cradle holders are simpler in design and reliable in operation.

Their manufacture is not particularly difficult. Their manufacture is carried out from plastic materials by molding in molds.

Claims (2)

SUMMARY OF THE INVENTION 1. A holder for crayons comprising a hollow body and a means for fixing crayons, including a pressure plate located inside the body, characterized in that the fixing means has stops and additional pressure plates integrated with the body and located inside it, all the plates are integral with the body and have a pointed end to interact with the chalk, and the distance between opposing plates is less than the distance between the respective stops. 2.
