Description
531 401 2 medan handtaget förs fram och åter och därvid bibringar skaftdelen med borsten ett helt annat rörelsemönster. 531 401 2 while the handle is moved back and forth and thereby the shaft part with the brush imparts a completely different movement pattern.
Figur l visar tandborstens handtag l, i vilket en skaftdel 2 är vridbart och förskjutbart lagrad i ett främre lager 3 och ett bakre lager 4. En borste 5 är utbytbart apterad i en koppling 6 på skaftdelen 2. På skaftdelen 2 är en rund permanentmagnet 7 fastsatt, medan två ytterligare, runda permanentmagneter 8,9 är glidbart lagrade på skaftdelen 2 på vardera sidan om den fastsatta permanentmagneten. De tre permanentmagneterna har polariteterna så riktade, att den på skaftdelen 2 fastsatta magneten 7 repelleras av de båda andra magneterna 8,9.Figure 1 shows the handle 1 of the toothbrush, in which a shaft part 2 is rotatably and slidably mounted in a front bearing 3 and a rear bearing 4. A brush 5 is interchangeably mounted in a coupling 6 on the shaft part 2. On the shaft part 2 is a round permanent magnet 7 attached, while two further, round permanent magnets 8,9 are slidably mounted on the shaft part 2 on each side of the attached permanent magnet. The three permanent magnets have the polarities so directed that the magnet 7 attached to the shaft part 2 is repelled by the two other magnets 8,9.
Lagren 3,4 tjänstgör san stoppklackar för dessa, mot vilka de hålls pressade av magnetkraften. men de kan naturligtvis även vara fästade vid lagren.The bearings 3,4 serve as stop lugs for these, against which they are kept pressed by the magnetic force. but they can of course also be attached to the bearings.
Såsom framgår av fig.l är vidare skaftdelen 2 försedd med ett radiellt utskjutande stift 10, som inskjuter i ett snett i förhållande till handtagets längdriktning anordnat spår ll i lagret 3. Spårets längd är avpassad till skaftdelens 2 slaglängd, och dess snedställning medför en vridning av skaftdelen ca 60°, vid skaftdelens rörelse i längdriktningen.As can be seen from Fig. 1, the shaft part 2 is further provided with a radially projecting pin 10, which projects into a groove 11 in the bearing 3 arranged obliquely in relation to the longitudinal direction of the handle, the length of the groove is adapted to the stroke of the shaft part 2, and its inclination of the shaft part approx. 60 °, when the shaft part moves in the longitudinal direction.
Fig.l visar ett utgångsläge med borsten 5 tänkt anligande mot icke visade tänder. I fig.2 förs handtaget l framåt medan borsten 5 hålls stilla på grund av friktionen mot tänderna, vilket medför att magneten 8 avlägsnas från magneten 7 medan magneten 9 närmar sig magneten 7, som allt starkare påverkas i riktning framåt. När borstens 5 friktion mot tänderna övervinns trycks skaftdelen 2 och borsten 5 framåt relativt handtaget l i en snabb och kort rörelse till det i fig.3 visade läget. samtidigt som skaftdelen 2 med borsten 5 vrids 60°, såsom beskrivits i anslutning till fig.l.Fig. 1 shows a starting position with the brush 5 intended to abut against teeth (not shown). In Fig. 2, the handle 1 is moved forward while the brush 5 is kept still due to the friction against the teeth, which means that the magnet 8 is removed from the magnet 7 while the magnet 9 approaches the magnet 7, which is increasingly strongly influenced in the forward direction. When the friction of the brush 5 against the teeth is overcome, the shaft part 2 and the brush 5 are pushed forward relative to the handle 1 in a fast and short movement to the position shown in Fig. 3. at the same time as the shaft part 2 with the brush 5 is rotated 60 °, as described in connection with fig. 1.
När handtaget l därefter dras bakåt, medan borsten 5 hålls stilla genom friktion mot tänderna, kommer magneten 8 att närma sig magneten 7, medan magneten 9 fjärnas från magneten 7, som därigenom påverkas i riktning bakåt tills borstens 5 friktion mot tänderna övervinns, varvid skaftdelen 2 med borsten 5 gör en snabb, kort rörelse bakåt under samtidig vridning till det i fig. 5 visade läget.When the handle 1 is subsequently pulled back, while the brush 5 is held still by friction against the teeth, the magnet 8 will approach the magnet 7, while the magnet 9 is removed from the magnet 7, which is thereby actuated in the rearward direction until the friction of the brush 5 against the teeth is overcome. 2 with the brush 5 makes a fast, short movement backwards while simultaneously turning to the position shown in fig.
Uppfinningen är självfallet inte begränsad till det här visade och beskrivna utföringsexemplet utan kan modifieras på åtskilliga sätt inom ramen för den av patentkraven definierade uppfinningen. Sålunda kan exempelvis handtagets bakre lager 4 vara förenat med handtaget 531 4Ü'§ 3 medelst gängor, så att lagrets läge i handtaget och därmed avståndet mellan magneterna 8 och 9 kan regleras.The invention is of course not limited to the exemplary embodiment shown and described here, but can be modified in several ways within the scope of the invention defined by the claims. Thus, for example, the rear bearing 4 of the handle can be connected to the handle 531 4Ü'§ 3 by means of threads, so that the position of the bearing in the handle and thus the distance between the magnets 8 and 9 can be regulated.
