Definitions
- This invention relates to a connecting means for connecting the parts of a multipart housing, more particularly for the two cup-shaped halves of a housing of synthetic material intended to receive an electrical device, for example of the housing of a dry-shaver.
- an electrical device for example of the housing of a dry-shaver.
- Such electrical devices which are operated on the power current mains, must first of all be reliably insulated so that accidents due to electrical current are, humanly speaking, impossible. Consequently, in such devices the live parts are usually arranged in a housing made of high-quality insulating material, more particularly of a modern synthetic material, so the involuntary contact with live parts is impossible even in the case of injudicious operation.
- the housing is usually formed so as to enclose the driving motor or the other live parts on all sides and comprises substantially two cup-shaped halves which, after mounting of the electrical parts, are reliably joined together.
- the present invention overcomes the above-mentioned disadvantages of known screwed connections and is characterized in that the housing has at least two projecting parts each of which is arranged on a part of the housing so that the one is a mirror image of the other a clasp engaging over the said projecting parts and pushing them against each other.
- each half of the housing has only one such projecting part of a comparatively large surface area and the prescribed mutual position of the halves of the housing can be exactly determined by dowel pins or similar means provided additionally.
- a clasp of resilient wire bent approximately into the shape of a rectangle with a ratio of the sides of about 1:2 or more is preferably made of.
- Such a clasp can be made in simple and cheap manner, the cost being especially low in comparison with the screws used hitherto, and such a clasp permits of obtaining an equally secure connection, which can, however, be established or be opened much more rapidly. In fact, for this purpose it is only necessary for the clasp to be slipped on or off the projecting parts.
- two relatively spaced projecting parts are arranged on or in each half of the housing, the distance between which from outer edge to outer edge corresponds to the long side of the rectangular clasp.
- the short side of the rectangle corresponds to the thickness of two closely justaposed projecting parts each of which is associated with one half of the housing.
- the long limbs of the clasp come to lie approximately at their center under lugs bevelled upwardly which are provided on the walls of the housing and if the clasp is bent in the rectangular plane so that the limbs engage one or each lug with initial stress.
- the lugs serve to lock the clasp in the mounted position and their upward bevelling permits simple mounting of the clasp since the long sides of the rectangle on being depressed are automatically bent inwards by the lugs until they snap under the lower edges of the lugs.
- the clasp may have one long side of the rectangle provided with an interruption located laterally at the center, which permits a very simple manufacture since the steel wire or the like which is used as the raw material need be bent only into the desired rectangular shape.
- the initial stress of the clasp in the mounted position may advantageously be obtained by an upwardly-directed bend of the longer portion of the side of the rectangle provided with an interruption.
- the long limb of this end of the clasp is bent from the imaginary horizontal plane of the rectangle in a slanting upward direction to obtain the shape desired.
- the lugs provided on the wall of the housing project inwardly far enough to ensure that, where the limbs of the clasp engage the outer edges of the projecting parts, the clasp is also securely held in position and can be disengaged from the lug and removed only by bending inwards the long limb of the clasp.
- Connecting means are thus obtained which after mounting, securely holds together the halves of the housing and which, on the other hand, can readily be loosened by bending inwards the limb of the clasp provided with an interruption until it is released by the associated lug, while in the loosened condition of the connection the clasp still remains fixedly secured to one half of the housing in that its other long limb is still held under the lug of this part of the housing.
- FIG. 1 is an elevation view of the upper part of the housing provided with the connecting means
- FIG. 2 is a View of this part from the bottom and FIG. 3 is a side view thereof; one half of the housing only being shown in FIG. 1 and the upper portion being shown in section in FIG. 3 for the sake of clarity.
- the embodiment shown relates to the housing made of synthetic material of a dry-shaver comprising two cupshaped halves 1 and 2, the electrical as well as mechanical parts of the shaver being omitted for the sake of clarity.
- the halves of the housing are substantially of the same configuration and each have in the upper part a recess 3 to receive the shaving head, which upper part only is shown.
- the shaving head engages over the recess 3 in the form of a cap, thus covering both the recess and the parts contained in it.
- a clasp 8 of resilient steel wire which is bent into a rectangular shape and which is so proportioned as to tightly embrace the lugs 4 and 7 in the mounted position (FIGS. 2 and 3).
- the long limbs of the clasp 8 are situated, as can be seen from FIGS. 2 and 3, under'lugs 9, bevelled upwardly which are provided on the side walls of the recess 3.
- These lugs hold the clasp 8 'in the mounted position, thus providing for an invariably rigid junction of the halves of the housing.
- the limb of the clasp located under the lug It is bent inwardly until it disengages from the lug, whereafter the clasp can be brought into the position shown in FIG. 1.
- the connection between the two halves of the housing is thus loosened and the apparatus can be opened and inspected. Nevertheless in this position, the clasp 8 remains fixedly con nected to the half 1 of the housing, since its long limb situated below is still held under the lug 9 which prevents it from sliding out. If it is desired to remove the clasp completely, it is necessary for the long limb under the lug 9 to be bent inwards until it disengages from the lug 9, whereupon the clasp can be pulled off upwards.
