Description detailed embodiments of the invention

The housing of the invention is shown ready for use in figure 1 .

It comprises an upper face 14 a rear 4 and a front face 5, a lower face 15 and side faces 20, 21.

According to the example shown, the front face 5 has a cutout 17 and the upper face 14 has a slot 16 running along the front face 5 and in communication with the cutout 17.

The upper face is part of a lid which snaps into engagement with a housing body 2 as shown in FIG. figure 3 .

The cover has four lateral faces whose rear face 4, the front face 5, side faces 20, 21 and said upper face 14.

The dispenser housing of the invention is designed to dispense flat objects 1, such as cutter blades 1.

It comprises a sliding support 3 or carriage, shown out of the housing on the figure 2 , which allows to push the blades to the front 5. The sliding support is received in the housing and guided to push the blades.

According to the example of the figure 3 , the housing body 2 comprises front faces 5 'and rear 4' facing the front and rear faces of the cover. It is however within the scope of the invention conceivable to design the cover without its front and rear faces and in this case the front and rear faces of the body of the housing become the front and rear of the housing. It is also possible to design the housing body without against sides, however in this case the filling of objects in the housing can not be done simply, objects having nothing to rely on until the lid is mounted.

For simplicity, the front faces 5 'are compared with the front faces 5, the whole against the front faces and front faces finally forming front and rear faces of double thickness.

In the case of the example represented in figure 2 the objects 1 are therefore stacked between the sliding support 3 and the front face 5 'of the body of the housing.

A notable aspect of the invention is that the sliding support is adapted to move between the rear face 4 'and the front face 5' of the housing body and that no space is lost between the support and the rear face 4 of the case. Indeed, according to the example shown, the sliding support pushes the objects 1 against the front face under the action of two elastic means 6, 6 'which each comprise a forward strand 6a and a return strand 6b and which are housed in spaces 13, 13 'on the lateral sides 20, 21 of the housing.

A first end or free end 61 of the strand go elastic means clings to an anchor point 7, 7 'of the housing and begins the strand go 6a.

A second end or free end of the return strand 62 of the elastic means hangs on an anchoring point 8, 8 'of the sliding support and ends the return strand 6b.

The forward strand 6a and the return strand 6b are connected to an axis or a pulley 9 disposed near the front face 5 of the housing.

It is understood that the elastic means are continuous and that the concepts of forward strand and return strand are only geometric representations, part of an elastic means may be part of the forward strand or back strand depending on the tension of the means elastic.

According to this construction, the elastic means are adapted to pull the sliding support from the rear face to the front face of the housing, without its length of travel being limited by the length of the elastic means relaxed. This is enabled by the fact that the forward strand can store the length of the relaxed elastic means or means. In particular, the elastic elongation ratio of the elastic means (s) and their attachment position on the casing body 2 can be calculated so that the displacement of the support from the rear face of the casing to the front face of the casing remains included in the race of elastic elongation of the elastic means.

An aspect ratio of preferably at least 2.5 to 3 appears usable within the scope of the invention.

The elastic means may in particular be elastics of natural or synthetic rubber or, as in the example shown, coil springs, these elastic means being adapted to slide on the axis 9 which, in the case of coil springs will be realized for example with a diameter large enough to avoid twisting the turns of the springs.

As represented in figure 3 , the housing comprises slides 11 intended to serve as guides for the objects and in particular slides of variable size and position may be provided depending on the shape of the objects.

Here the slides 11 support the blade 1 at a portion 100 set back from the wire 101 of the blade.

If the slides do not serve as a guide for the sliding support, the groove 12 in which the slides move is made wider than the spacing of the rails to not hinder the movement of the sliding support.

According to figure 4 and 5 more particularly, the housing body has internal side walls forming lateral housings 13, 13 'in which the resilient means 6, 6' are arranged. These housings run along two opposite sides of the sliding support.

The walls 13a, 13b serve as guiding means of the sliding support in cooperation with the lateral faces of said support, these lateral faces carrying the pins 8, 8 'receiving the end of the springs 6, 6'.

On one side, the inner side wall 13a is limited in height to allow the passage in the housing 13 of a first pin 8 for fixing a first elastic means 6 on the support. On the second side, the wall comprises a groove 131 for the passage of the pin 8 'represented in figure 5 .

According to this embodiment, the pins are offset in height so that the fastenings of the springs on the pins 8, 8 'of the support and on the pins 7, 7' of the casing body are reversed, which allows a better balance of forces. on the sliding support 3.

As seen above, the housing comprises an opposite and parallel lower face 14 and a lower face 15 and the upper face is, in the example shown, made in a housing cover and the rear face is a base of the housing body 2.

The objects stacked between the support and the front face are retained by these upper and lower faces or as in the example, by the upper face and the guide rails 11.

The slot 16, which runs along the front face 5 of the housing, constitutes an object distribution slot.

The cutout 17 described above, made in the front face 5 of the cover and the front face 5 'of the housing body, allows to push objects bearing under the front face out of the housing through the slot 16 distribution as shown in figure 1 . According to this example and for safety reasons, the blades 1 are arranged so that their attachment portion without cutting edge is on the side of the cutout 17.

In alternative realization according to the figure 6 , the front face comprises a means 18 for pushing objects from above the stack of objects made between the support 3 and the front face 5 outside the housing through the distribution slot 16 'which is here placed in a face lateral of the case.

In this case, the thrust means 18 is for example a sliding pusher recalled or not by a spring. This more complex solution to achieve the benefit of sink push objects with the fingers.

The housing of the invention is compact and an exemplary embodiment is a housing of 80x80x20mm for enclosing 100 blades of the deburring blade type, the sliding support being actuated in such a case by coil springs of 4 mm in diameter having a 45 mm hook-on distance and adapted to reach a length of 140 mm without plastic deformation.

These dimensions are of course given as an indication, many variants of the box of the invention can be made.
