Definitions

  • the present invention relates to a handle for application to an elongated element such as the shaft of an implement or tool. It has proved in many situations that the shafts present on
  • a grip is provided according to the invention, which is characterised by a handle sleeve, an operating part capable of being turned relative to the sleeve about the geometric axis of the sleeve and of being fixed in the desired rotational position relative to
  • Fig. 1 is a partly cut-away side view and shows a handle with a toothbrush inserted therein;
  • Fig. 2 is an end view and shows the handle seen from the line II-II in Fig. 1; and Fig. 3 is an end view according to Fig. 2, but shows the shank of the toothbrush locked in the handle.
  • Handle 1 which is shown in the drawing has a cylindrical handle sleeve 2, an operating part 3 which is also shaped as a sleeve and can be turned relative to handle sleeve 2 about the geometric axis of handle sleeve 2, and an engagement part also shaped as a sleeve which is arranged within the two other sleeves 2, 3.
  • the inner sleeve constituting the engagement part has at one of its ends a flange 5 which rests on the outer end of handle sleeve 2 and is non-rotatably connected with the latter by means of a lug 6, and at its other end a claw element 7 engaging the outer end of operating part 3 and non-rotatably connected with the latter.
  • the inner sleeve has three separate helical slots subdividing the section into three separate helical spring units 4.
  • arrangements can of course be selected with both a smaller and larger number of slots or use can be made of an arrangement with several spring units 4 arranged in sequence.
  • Handle sleeve 2 and operating part 3 have, at their ends facing each other, an anti-rotating device formed by gear rims with a saw-tooth gear profile, which are kept in engagement with one another as a result of the fact that spring unit 4 of the engagement part is prestressed. It is of course possible to select instead of the gear profile shown also a different suitable gear profile or an arrangement with a recess in handle sleeve 2 and a lug element in operating part 3 or vice versa.
  • the shaft of an implement or tool is inserted into spring unit 4 of the engagement part and operating part 3 is turned relative to handle sleeve 2 in the direction causing the diameter of spring unit 4 to diminish and its helical arms to lock the shaft within the handle firmly.
  • the gear rims of handle sleeve 2 and operating part 3 ride on one another without causing any signi- ficant resistance and lock handle sleeve 2 and operating part 3 against one another as soon as the turning motion has ceased.
  • Operating part 3 may, for instance, be made in one piece with the engagement part and may, if required, have the shape of a long shaft. But it is also possible, in order to avoid any danger of pinching, to arrange a collar outside the locking element, which can in addition serve for controlling operating part 3 in relation to handle sleeve 2, thus making it possible to arrange within the latter a longer spring unit.

Abstract

Manche (1) à monter sur un élément de forme allongée (10), tel que le tronc d'un instrument ou d'un outil. Ledit manche comporte un manchon de manche (2), un élément mobile (3) que l'on peut tourner par rapport au manchon (2) autour de l'axe géométrique du manchon (2) et fixer dans la position de rotation voulue par rapport à celui-ci, un élément d'engagement, disposé à l'intérieur du manchon de manche (2) et ayant la forme d'au moins une unité de ressort hélicoïdale (4), dans lequel s'insère l'élément de forme allongée (10), et qui est fixé à l'une de ses extrémités de manière rotative au manchon de manche (2) et à l'autre extrémité à l'élément mobile (3). Le diamètre de l'unité de ressort (4) diminue ou augmente en fonction du sens de rotation de l'élément mobile (3), diminuant quant on le tourne dans un sens et augmentant quand on le tourne dans l'autre sens.
