Abstract

The glove box has a sleeve (2) for a bag (4), more particularly a glove, which is held in place between the inside of the sleeve (2) and an elastic ring (7) which is snapped into the sleeve (2). <IMAGE>

Description

SPECIFICATION Glove box This invention relates to a glove box having a housing which is provided with an opening defined by a sleeve in which a bag, more particularly a glove, is held so that it is positioned between the inside of the sleeve and an elastic ring.

A sleeve for a glove box of this type is known from Prospekt 970 issued by Pedrolit GmbH of Zurich. The elastic ring is an O-ring and is deformable. On the inside of the sleeve there is an annular attachment groove having a circular cross-section into which the ring, together with the gloove, is pressed by deforming the cross-section of the ring. When it is pressed into the attachment groove, the closed ring assumes its original circular crosssection again so that it is held in the attachment groove.

However, providing the inside of this known sleeve with the attachment groove is particularly expensive in terms of time and cost.

Moreover, the cross-section of the attachment groove, the glove thickness and the crosssection of the O-ring must be exactly matched if the desired sealing and holding effect is to be achieved. Also, fitting the glove in the sleeve is very time-consuming as the closed ring must be pressed precisely into the attachment groove.

It is desirable to remedy this and to provide a glove box with a sleeve which can be manufactured more economically. Also, it is desirable for it to be possible to fit bags or gloves of almost any thickness into the sleeve in a considerably simplifed manner but nevertheless in a manner such that they are proof against tension, and sealed.

According to the present invention, there is provided a glove box having a housing which is provided with an opening defined by a sleeve in which a bag or glove is held in place between the inside of the sleeve and an elastic ring, wherein the ring is able to be snapped into the sleeve.

In this way, a seal is achieved between the bag or glove and the sleeve defining the opening in the glove box housing even when the inside of the sleeve is completely smooth and has absolutely no profile. Also, the ring can be snapped in the sleeve very quickly without the use of tools, and may be removed from the sleeve without using tools, for example by pulling it in a radial direction by means of a band wound around the ring. Also, the snapped-in ring fits the inside of the sleeve snugly at all points and thus ensures that there is an overall uniform seal. This applies particularly when the ring is closed and also when the cross-section of the sleeve is not entirely circular, but, for example, oval.

Advantageously, the ring is formed by a band and the width of the ring is greater than the thickness of the band. This ensures that the ring fits the inside of the sleeve snugly over a large surface with the same application force at all points so that there is acting on the bag or glove a sealing and pressing force which is entirely evenly distributed over a large area and which does not stretch or flatten the bag or glove and therefore considerably lengthens its service life.

The invention will now be described, by way of example, with reference to the drawings in which: Figure 1 is a partial longitudinal section of a sleeve of-a glove box according to the invention; Figure 2 is a scaled down front view of the sleeve shown in Fig. 1; and Figure 3 is a view according to Fig. 2, during fitting or removal of the ring.

Figs. 1 to 3 show a hollow, cylindershaped, tubular sleeve 2 which defines an opening of a housing 3 of a glove box, and which has a flange 2a which is bonded to the inside of the housing 3.

The open end of a glove 4 made of a plastics material is inverted over the end of the sleeve 2 located on the outside of the housing 3, the finger end (not shown) of the glove being located in the glove box. The open end of the glove 4 terminates in an annular bead 5 which is located in an annular groove 6 at right angles to the longitudinal axis of the sleeve 2 in the outer surface of the sleeve 2, outside the housing 3.

The glove 4 is held on the inner surface of the sleeve 2 by an elastic ring 7 which is snapped into the sleeve 2 and presses the glove entirely evenly against the inner surface of the sleeve 2 to give a snug fit.

Advantageously, the ring 7 consists of acrylonitrilebutadiene rubber which, although elastic, is only slightly deformable (or at least is definitely not irreversibly deformable).

To fit the glove 4 in the sleeve 2, the open end of the glove is inverted over the outer surface of the sleeve 2, and then the gloove is pushed through the sleeve 2 into the interior of the glove box. The ring 7 is then depressed radially inwards, as shown in Fig. 3. The depressed ring is then inserted into the sleeve 2 and released so that the ring 7 again assumes its original shape and snaps into the sleeve 2 so as to be secured in place. If necessary the ring 7 can be pushed out by hand in the radial direction.

To remove the ring 7 and thus also the glove 4, the ring 7 is depressed again, as shown in Fig. 3, by radial tension on a band 8. Thus depressed, the ring 7 can be easily removed from the sleeve 2.
