Definitions
- the invention relates to a holder for rod-shaped objects, such as chalks, mines or erasers, which consists of a shaft and a slide, which is formed by a particular chalk recording, from which protrudes an upper spring-mounted arm, which passes through an elongated guide slot and is provided with a button.
- a holder for rod-shaped objects such as chalks, mines or erasers
- which consists of a shaft and a slide, which is formed by a particular chalk recording, from which protrudes an upper spring-mounted arm, which passes through an elongated guide slot and is provided with a button.
- the chalk used for writing, painting or marking rubs off slightly and smears the user's fingers and clothing. In addition, the chalks break frequently.
- This problem tries e.g. to solve the CZ utility model no. 173321, which relates to a holder in which a slider is mounted with a protruding through an elongated slot actuator button. On both sides of the slot, there are a number of transverse slots, which engage in the detents of the actuating button.
- a disadvantage of this solution is that the open slots leave a path open for impurities and that the tongues break off between the slots after a short time.
- a chalk holder consisting of a shank and a slider formed by a chalk-shaped receptacle from which an upper spring-mounted arm protrudes, which passes through an elongate guide slot and is provided with a key. From the receptacle emerges a lower rigid arm which is mounted on at least one guide rail in the shaft, wherein the upper arm carries on the upper side at least one tooth which engages in the direction perpendicular to the direction of the feed grooves on the lower Side of an upper wall of the shaft are formed.
- the lower arm may advantageously be provided with a stop to limit the stroke of the key.
- the shank of the chalk holder may be triangular or quadrangular in cross section, the mouth of which is formed by a round or triangular or square collet chuck with an elastic sleeve.
- the shaft is in two parts, wherein both parts hold together by an elongated positive connection.
- the chalk holder of Fig. 1 to 3 consists of a shaft 1 made of plastic and a slide 2, also made of plastic.
- chalk 3 is pushed from the round cross-section and held in a receptacle 4 of the slider 2.
- From the receptacle 4 emerge two arms 5, 6, wherein a lower rigid arm 5 on the lower side has a groove which slides on a guide rail 7, which is formed in the interior of the shaft 1.
- An upper arm 6 is resiliently mounted on the receptacle 4. It is formed by a strip 8 provided on the upper side with teeth 9 and a button 10.
- the key 10 passes through an elongated guide slot 11 guided in an upper wall 12 of the shaft 1.
- the teeth 9 on the upper side of the bar 8 engage in grooves 13 which are perpendicular to the elongated guide slot 11 and in rows on the lower side upper wall 12 of the shaft 1 are formed.
- a stop 14 is attached, which limits the lower position of the upper arm 6 and thereby the key 10.
- the shaft 1 here has a triangular cross-section with rounded edges and its mouth is formed by a round collet 15 with an elastic sleeve.
- the cross-section may be quadrangular and the collet may in turn be quadrangular.
- the shaft 1 is in two parts, wherein both parts hold together by an elongated positive connection.
- the chalk 3 is inserted into the receptacle 4 and clamped therein. After pressing the button 10 you can regulate the pushing out of the chalk 3 from the collet 15 by the key 10. After the release of the key 10, the teeth 9 engage in respective grooves 13 on the inner side of the shaft 1 and lock the chalk 3 in the desired position.
