Abstract
Abstract The invention relates to a laying nest for at least one chicken or other type of egg-laying poultry, the laying nest being provided with a floor which has a slight slope towards a collecting device for the eggs laid by the poultry, over which floor a sweeper member can swing for removal of poultry from the floor, which sweeper member is attached for pivoting to a shaft extending above the floor in a horizontal plane.
The invention has for its object to give a laying nest a form such that turning out can be performed automatically and virtually without checks being necessary, for instance with automatically controlled hydraulic, pneumatic or electr-ical means.
In order to realize this object the invention proposes a laying nest of the type described which has the feature that the sweeper member is coupled via spring means to operating means which possess two stable, extreme positions, in which first position the sweeper member is forced by the spring means to an inactive rest position, and in which second posi-tion the sweeper member is forced by the spring means to a second inactive rest position via a swinging movement such that any poultry that may be present on the floor is subje-cted to a turning out force from the sweeper member as a result of the tensioning in the spring means caused by the operating means.

to an operating means that is movable between two stable, limiting positions, in a first of which said sweeper member i8 urged by said spring means to a first inactive rest position, and ln a second of which said sweeper member i8 urged by æaid spring meanæ
to a second inactive rest position, movement of said operating means to said second extreme position being effective to move said sweeper to said second lnactive positlon through a swinging movement such that any poultry that may be present on the floor is sub~ected to a turning out force from sald sweeper member aæ a result of the tensloning in said spring means caused by such movement of sald operating means.
Use of the lnventlon ensures that the anlmalæ to be turned out are subjected to only a comparatlvely llght turnlng out force from the sweeper member, as a result of whlch they are gradually forced off the floor.

:
despite activation of the operating means, stands still in an intermediate position. With this embodiment an operative can take the necessary steps, particularly to remove a dead anim-al.
A very simple embodiment displays the feature that the shaft carries an operating handle.
An importan~ variant has the characteristlc that the laying nest comprises a house with a passage opening and that the sweeper member forces the poultry for turning out to and through this passage opening.
At least one flexible sheet is preferably suspended on the top edge of the passage opening to at least partially cover the passage opening.
This flexible sheet has preferably a violet-like colour.
A violet colour has been found to stimulate the tranquility of the animals and to draw the animals to the nests, æo that they only lay eggs there and not in other places.
In a very simple embodiment, in which the laying nest comprises a house, the shaft is mounted in holes arranged in walls of the house.
. ~ , .
~ A preferred embotiment has the particular feature that ., .
the house possesses a second passage opening for passage of lai~d eggs to the collecting device, to the upper edge of which opening;is attached a flap. This prevents the animals belng subJected to a draught, which is unpleasant for them, and from~'destroying eggs lying on ~he collecting device by pecking at them, since they are then withdrawn f~rom~v~ew. ~
A very simple embodiment is that in which the floor comprises~a b~ase board having artificial 'turf~'laid on~;le. The ~floor~can in this way~be removed and cleaned very'simply.
In order to prevent animals occupying a position on the house of a laying nest a variant can be employed~1n which~the house possesses a roof with a ridge and that placed for pivot-~ lng on this ridge is a gutter with a V-shaped cross section, `~ 35 which gutter is forced by spring means to a rest position in which the legs of the V are directed upward, whereby the , ~
.`, "~
force to be applied by the spring means is insufficient to allow the gutter to support a poultry animal. Very simple, cheap and light is the embodiment in which the sweeper member comprises trellis work.
If required multiple laying nests can be accommodated in one house, or various laying nests, whether or not with a house, can be linked with one another.
The automatic laying nest according to the invention offers great labour saving compared to the known laying nests referred to, because brood animals are pushed automatically ; from their nesting places.
With the laying nest as according to NL-A-8204139 the animals have to be pushed off their nest during the day so that the eggs can be picked up. With the nest according to the invention this takes place in the evening, when the anim-als are no longer laying eggs. The invention will now be elucidated with reference to the drawing of several embodim-ents. In~the drawing:

Present for that purpose in the lowest portion of the rear wall 8 is a passage opening 12 which is covered by a flap 13 to prevent draught.
Hanging from the lower edge oE the roof 9 is a flap 14 which is violet coloured. Thus is available a draught-free, shady space that is pleasant for the animals.

~ -The trellis work 15 is attached for pivoting to a shaft 21, with respect to which reference is made to fig. 5, and is mounted relative thereto by means of a bearing bush 22. Shaft 21 is mounted in holes 23 which are arranged in the vertical end walls 6, 7. This mounting is such that the shaft can only rotate when overcoming a certain friction force. Locking means can also be present for securing the shaft in the two extreme positions.
The shaft 21 bears projections 24. Arranged between each projection 24 and trellis work 15 is a draw spring 25.
Attached to the outside end of shaft 21 for rotation of same between two extreme positions is an operating handle 26.
It can be seen in fig. 4 that in the position of the operating handle 26 indicated with drawn lines the draw spring 25 occupies a position such that it pulls the trellis work 15 to its first rest position indicated with drawn lines. This ~-~iK the position of the trellis work in which an animal 27 can sit on the artificial turf 11 without being turned out. Should an operative wish to turn out the animals 27, he then pulls I ~
';~20 ~handle 26 over to the position indicated by 26', which is ~shown with~da~shed lines. As a result of the rotati~on ~of shaft '~21'the pro~ect~ion 24 is~also rotated to the position lnd~icated ' w~ith~ 24', ~in which the~ spring 25 comes into~t~he~p~osition `desig~nated~by-~25' locat~ed at the other side of the "swing~

Fig. 1 shows schematically signalling means 29 for emit-ting a warning signal in the case where, despite operation of the lever 26 as according to arrow 30 (see fig. 4), the trel-lis work 15 stands still in an intermediate position, forexample the position 15', or at least a posit~on not corres-ponding with the end rest position after displacement of the trellis work as according to arrow 28. After such a rest position has been reached, the animals can no longer enter the laying nest. Only after resetting of the handle from position 26' to position 26 is the laying nest again at the disposal of the animals.
Finally, fig. 6 shows the ridge 30 of roof 9. The ridge 30 carries a gutter 31 having a V-shaped cross section which is disposed for pivoting by means of a shaft 31 and a bearing 32, and which is forced by a spiral spring 33 to the rest position shown in fig. 6. In this rest position the surfaces 34, 35 of gutter 31 are directed upward. The purpose of this construction is to prevent animals taking up position on the ridge 30 of the roof. As soon as they take up position on gutter 31, a swinging over of the gutter must be carried out 80 that the animals do not find a stable surface on which to rest. The force to be applied by the spring 33 must~t~he,refore also be insufficient to allow the gutter 31 to support an anima~l 27.~
A laying nest according to the invention pr~eferably takes a Du~ltip1e form. A chicken is a com-unity~-an1mal -and likes to lay eg,gs in a communal space.

electrical driving is employed as force generating means.
Fig. 1 shows schematically signalling means 29 for emit-ting a warning signal in the case where, despite operation of the lever 26 as according to arrow 30 (see fig. 4), the trel-lis work 15 stands still in an intermediate position, forexample the position 15', or at least a posit~on not corres-ponding with the end rest position after displacement of the trellis work as according to arrow 28. After such a rest position has been reached, the animals can no longer enter the laying nest. Only after resetting of the handle from position 26' to position 26 is the laying nest again at the disposal of the animals.
Finally, fig. 6 shows the ridge 30 of roof 9. The ridge 30 carries a gutter 31 having a V-shaped cross section which is disposed for pivoting by means of a shaft 31 and a bearing 32, and which is forced by a spiral spring 33 to the rest position shown in fig. 6. In this rest position the surfaces 34, 35 of gutter 31 are directed upward. The purpose of this construction is to prevent animals taking up position on the ridge 30 of the roof. As soon as they take up position on gutter 31, a swinging over of the gutter must be carried out 80 that the animals do not find a stable surface on which to rest. The force to be applied by the spring 33 must~t~he,refore also be insufficient to allow the gutter 31 to support an anima~l 27.~
A laying nest according to the invention pr~eferably takes a Du~ltip1e form. A chicken is a com-unity~-an1mal -and likes to lay eg,gs in a communal space.

Claims (13)
1. Laying nest for at least one chicken or other type of egg-laying poultry, said laying nest having a floor with a slight slope towards a collecting device for eggs laid by the poultry, over which floor a sweeper member is mounted to swing for removal of poultry from said floor, said sweeper member being attached to a pivotal shaft extending horizontally above said floor and being coupled via spring means to an operating means that is movable between two stable, limiting positions, in a first of which said sweeper member is urged by said spring means to a first inactive rest position, and in a second of which said sweeper member is urged by said spring means to a second inactive rest position, movement of said operating means to said second extreme position being effective to move said sweeper to said second inactive position through a swinging movement such that any poultry that may be present on the floor is subjected to a turning out force from said sweeper member as a result of the tensioning in said spring means caused by such movement of said operating means.
2. Laying nest as claimed in claim 1, wherein said pivotal shaft can be rotated by the operating means between two limiting angular positions and carries at least one radial projection, said spring means comprising a tension spring being connected between said projection and said sweeper member, said projection being so located that in the first limiting position of said operating means said spring pulls said sweeper member towards said first rest position, and in the second limiting position of said operating means said spring pulls said sweeper member towards said second rest position.
3. Laying nest as claimed in claim 1, wherein the turning out force to be applied by the spring means is insufficient to displace a poultry animal from the floor.
4. Laying nest as claimed in claim 2, wherein the shaft carries an operating handle.
5. Laying nest as claimed in any one of claims 1 to 4 wherein the laying nest scomprises a house with a passage opening, and that the sweeper member forces the poultry for turning out to and through this passage opening.
6. Laying nest as claimed in claim 5, wherein at least one flexible sheet is suspended on the top edge of the passage opening to at least partially cover said passage opening.
7. Laying nest as claimed in claim 6, wherein the flexible sheet has a violet-like colour.
8. Laying nest as claimed in claim 5, wherein the pivotal shaft is mounted in holes arranged in walls of the house.
9. Laying nest as claimed in claim 5, wherein that the house possesses a second passage opening for passage of laid eggs to the collecting device, to the upper edge of which second opening is attached a flap.
10. Laying nest as claimed in any one of claims 1 to 4 or 6 to 9 wherein the floor comprises a base board having artificial turf laid on it.
11. Laying nest as claimed in claim 5, wherein the house possesses a roof with a ridge and that placed for pivoting on this ridge is a gutter with a V-shaped cross section, which gutter is forced by resilient means to a rest position in which the legs of the V are directed upward, wherein the force to be applied by said resilient means is insufficient to allow said gutter to support a poultry animal.
12. Laying nest as claimed in any of claims 1 to 4, 6 to 9 or 11 including signalling means for emitting a warning signal in the case where, despite activation of the operating means, the sweeper member remains in an intermediate position.
13. Laying nest as claimed in any of claims 1 to 4, 6 to 9 or 11 wherein the sweeper member comprises trellis work.
