No. 429,440 Claims priority, application Netherlands, Feb. 29, 1964, 6,402,050 4 Claims. (Cl. 220-4) The invention relates to a vacuum cleaner comprising a housing consisting of at least two parts and a handle which is rotatably secured to one of the parts of the housing and which is provided with means for detaching a latch or lock joining the two parts of a housing so they can be separated by linear parting movement and likewise reunited.
The invention will now be described more fully with reference to the accompanying drawing, in which:
FIGURE 1 is a perspective view of a vacuum cleaner in accordance with the invention,
FIGURE 2 is a longitudinal section of an embodiment of the invention,
FIGURE 3 is an elevation of a second embodiment of the invention, viewed from the inside (the wall of the housing having been removed partly),
FIGURE 4 is a section taken on the line IV-IV of FIGURE 3,
FIGURES 5 and 6 represent details of the construction shown in FIGURES 3 and 4,
FIGURE 7 shows a variant of the second embodiment,
FIGURE 8 is a section taken on the line VIII-VIII of FIGURE 7, and
FIGURE 9 shows a detail of this embodiment.
The vacuum cleaner comprises a housing consisting of two parts 1 and 2, the part 2 being provided with a suction opening 3, while an exhaust opening 4 is provided in the part 1. The part 1 comprises the motor and the impeller which partly extend into the part 2. The part 2 comprises the dust bag which may be secured to the part 1.
A carrying strap 5 is secured to the part 2. The points of rotation of this strap are located on either side of this part in a protuberance 6 which is prolonged along the side wall of the part 1, and which also accommodates the means for joining the two housing parts together.
The carrying strap extends through the slot 7 of the protuberance 6.
In the embodiment shown in FIGURE 2, the carrying strap 5 is rotatably secured around a pin 8. The means for joining the two housing parts consist of a pin 9 secured to the edge of the housing part 1 or to the edge of the protuberance 6 and of a strap 10 which is secured to the housing part 1 and the bent end of which is adapted to snap across this pin. The end 12 of the strap 5 bent around the pin 8 is provided with a stop 13 which, when the strap is moved to the right-hand side, may get into touch with a stop 14 secured to the strap 10 and which may lift the latter from the pin. The bent portion 15 of the carrying strap 5 also acts as a stop and when the carrying strap is moved to the left-hand side, it may be urged to snap across the pin 9. When the carrying strap is moved to the right-hand side, the housing parts 1 and 2 are consequently separated from each other, while they are joined together upon displacement to the left-hand side.
In the embodiment shown in FIGURES 3 to 6, the carrying strap 5 is rotatably journalled in a circular recess 16 in a ring 17 which in turn is rotatably journalled on a pin 18 rigidly secured to the wall of the housing part 2.
The recess 16 is locally prolonged as far as the outer edge of the ring 17, so that two stops 19 and 20 are formed between which the carrying strap 5 with respect to the ring 17.
Viewed in the axial direction, the ring 17 has beside the recess 16 a part 21 of smaller diameter through which a pin 22 extends eccentrically.
For joining the two housing parts together, provision is further made of a locking plate 2.3 which is slidably arranged in the protuberance 6 and a lock 24 which is rigidly secured to the housing part 1.
The plate 23 is provided with a recess 23 into which fits the part 21 of the ring 17. The pin 22 of this ring bears on the edge 26 of the recess 25. The plate is further provided with a recess 27 into which the lock 24 is adapted to grip, a bent edge 28. Plate 23 is also provided with two bent edges 29 and a part 30 around which a compression spring 31 may be disposed. This spring urges on the edges 29 while its other end bears on the face 32 of the wall of the protuberance 6. Consequently, this spring exerts a pressure to the left on the plate 23.
When the carrying strap is moved to the left, it engages the stop 19 of the ring 17. When the strap 5 is moved further to the left, the ring 19 follows the movement of the strap 5, as a result of which the pin 22 is also taken along. The plate 23 is then moved to the left. As soon as the strap 5 abuts against the edge of the opening 7 in the protuberance 6, the plate 23 is moved further to the left under the influence of the spring 31 and takes along the pin 22 and consequently also the ring 17. During this movement of the plate 23, the latter deviates slightly from its rectilinear path as a result of the fact that the ends of the bent tongs 29 slide across the oblique faces 33 joined with the wall 6, while the corner 34 of the plate slides across the cam 35 which is secured to the wall of the housing. This movement is further rendered possible by the conical shape of the walls of the narrowed part 21 of the ring 17. After the plate 23 has reached its extreme left position (indicated by broken lines), it is no longer within reach of the lock 24 secured to the housing part 1 and the two housing parts may be separated. When the carrying strap is moved to the right, it rotates first with respect to the ring 17 until it bears on the stop 20. The ring is then taken along, as a result of which the pin 22 urges on the edge 26 of the plate and the plate 23 is moved to the right against the pressure of the spring 31. This movement is continued until the pin 22 has reached again the position shown in FIGURE 3. The edge 36 of the hole 27 in the plate 23 then grips the hook 24 and consequently pulls the housing part 1 tightly against the part 2.
FIGURES 7-9 show a variant of the embodiment described hereinbefore. In this variant, the ring 17 is provided with a flange 37, the edge of which has a recess 38. The ends of the carrying strap are provided with a fiat part 39 in which an elongated hole 40 is: provided through which the strap 5 is journalled on the pin 18. The elongated hole permits a movement of the strap in the longitudinal direction with respect to the ring, as a result of which a pin-shaped part 41 may be introduced into the recess 38 so that the carrying strap may be coupled with the ring 17. After the coupling between the carrying strap and the ring has been established, the arrangement operates in quite the same manner as that described hereinbefore.
It should be appreciated that the coupling between the carrying strap 5 and the ring 17 may also be established in a different manner. For example, the carrying strap may be moved in an axial direction on the pin 18 while it is joined with the ring 17. It is also possible to provide the end of the carrying strap with a pin-shaped projection which grips into a recess of a radially protruding flange of the ring. These and also other variations are possible without leaving the scope of the invention.
