Definitions

  • the invention relates to a brush, in particular a toothbrush, with a brush head arranged in the extension of a handle and provided with bristles.
  • the brush head In the case of the usual brushes of this type, the brush head is rigid.
  • the brush head can be concave or convex.
  • the brush head is flexible at least in one plane and that a pulling and pushing element acts on the end of the brush head remote from the handle, which is attached on the other hand to an actuating member which is adjustably received on the handle.
  • the pulling and pushing element can expediently be designed as a band-shaped leaf spring. Such an element can advantageously adapt easily to each curvature while maintaining the pulling or pushing effect and also results in an elastic restoring force.
  • a further advantageous measure can consist in the brush head having a flexible strip which receives the bristles and which is provided with portal-shaped yokes arranged one behind the other in the longitudinal direction.
  • the yokes which are arranged one behind the other at a distance, create a tunnel for a protected arrangement of the pulling and pushing elements and at the same time allow the required mobility of the brush head.
  • Figure 1 is a side view of an inventive
  • FIG. 2 shows the arrangement according to FIG. 1 with the brush head extended
  • FIG. 3 shows the arrangement according to FIG. 1 with a concave curved brush head
  • Figure 4 is a plan view of the toothbrush according to the invention.
  • Figure 5 shows a cross section through the brush head.
  • the toothbrush on which the drawing is based consists of a handle-shaped handle 10 which carries a brush head 11 arranged in its extension. This is provided with bristle tufts 12 arranged in a row.
  • the brush head 11 can be flexibly deformed in the direction parallel to the central longitudinal plane of the brush, ie it can be arched with respect to an axis running transversely to the central longitudinal plane.
  • the brush head 11 can be brought from the bristle-side convex curvature on which FIG. 1 is based, via the stretching position on which FIG. 2 is based, to the concavely arched position on which FIG. 3 is based.
  • the brush head 11 consists, as can best be seen from FIG. 5, of a flexible base strip 11a molded onto the handle, into which the bristle tufts 12 are inserted, and on the side facing away from the bristle tufts .12 is overlapped by portal-shaped yoke elements 11b arranged one behind the other at a distance. These accordingly limit a tunnel 18 passing through the brush head 11.
  • the underside of the base strip 11a is flush with the underside of the adjacent handle 10.
  • the top of the yoke elements 11b merges flush with the top of the adjacent handle 10. Gaps 13 are provided between the adjacent yoke elements 11b.
  • the base strip 11a receiving the bristle tufts 12 practically functions as a spring strip which, after a deflection, automatically returns to the extended position on which FIG. 2 is based.
  • a pulling and pushing element 14 engages through the tunnel 18, which on the other hand is fastened to an actuating member 16 in the form of a lockable sliding cam which is slidably received on the handle 10.
  • the push and pull element 14 is designed as a band-shaped leaf spring, the ends of which can be pinned to the base strip 11a or the actuating member 16, as indicated at 15.
  • the leaf spring forming the push and pull element 14 is moved to the office by moving the actuating member 16 " . sten head compressed and tensioned by moving the actuator 16 away from the brush head 11. Since the pulling and pushing element 14 engages over the base strip 11a, this is, as shown in FIG.
  • the base strip 11a is arched upwards, ie concavely on the bristle side.
  • the section of the leaf spring forming the pulling and pushing element 14 penetrating through the tunnel 18 can be designed by shaping or pretensioning such that an upward curvature occurs in the event of a compression.
  • the sliding cam forming the actuating member 16 can, as can best be seen from FIG. 4, be provided with a pin 17 engaging in a groove 19 of the handle 10.
  • the pulling and pushing element 14 is fastened to this in the example shown.
  • the groove 19 has a plurality of notches 20, which are formed here by bore-shaped cross-sectional expansions, into which the pin 17 can be latched when the actuating member 16 is moved.
  • the cross section of the pin 17 acting as a locking head corresponds approximately to the cross section of the cross-sectional expansions of the groove 19 functioning as locking notches 20.
  • the locking notches 20 are each assigned different curvatures of the brush head 11. In the example shown, only three notches 20 are indicated, the middle notch of the stretching position on which FIG. 2 is based and the two outer notches of the bulges on which FIGS. 1 and 3 are based. should be assigned to bundles. If further intermediate positions are to be adjustable in addition to the extreme positions shown, further locking notches are simply to be provided.
  • the groove 19 can be positioned on the handle 10 so that it connects directly to the tunnel 18 of the brush head 11.
  • the groove 19 is spaced from the brush head 11.
  • the handle 10 is provided with a guide channel 21, which opens on the one hand into the tunnel 18 and on the other hand into the groove 19 and is formed by a longitudinal recess, through which the leaf spring forming the pulling and pushing element 14 can be pushed.
  • the guide channel 21 results in exact straight guidance of the push-pull and push-in element 14, so that it cannot deflect on the handle side.
  • the clear cross section of the tunnel 18 is enlarged compared to the cross section of the pulling and pushing element 14.

Abstract

La présente invention décrit une brosse, plus particulièrement une brosse à dents, comprenant une tête de brosse (11) à l'extrémité d'un manche (10). La courbure de la tête de brosse peut être modifiée pour passer d'une forme concave à une forme convexe et réglée en fonction de l'utilisateur, au moyen d'un élément de traction et de poussée (14) qui peut être déplacé par un organe d'actionnement (16) fixé sur le manche (10).
