Definitions

  • the object of the invention is a device for eliminating play and displacement of the ends of the staves constituting the bearing surface of the mattress of a stave bed base.
  • the staves are normally engaged by their ends in seats created by joint supports or trimmed ture received and sliding in a slot made at least on two opposite sides of the frame between which the staves are placed. Because of the tolerances required both in the manufacture of the chassis and in the components of the seats for the ends of the staves, there is often a clearance along one side or each side of the frame, where the supports for the staves can present slight displacements with elimination which provides the device in question.
  • the above supports have lateral housings facing the seat for the moat, and on each side of the frame, in two opposite housings of two contiguous joint supports, is placed a spacer able to separate between them the two aforementioned supports with the elimination of all play between the supports placed in the aforesaid side of the chassis.
  • This spacing element may comprise at least one elastic extension member in order to elastically force the above two contiguous supports to move apart.
  • said spacing element may comprise a bar made of rigid material and be engaged at least in one of the above two contiguous supports after having spread the above supports between them in order to make up for the play; this engagement can be achieved using dowels, nails or similar means; in the other support the spacer can be engaged by abutment on the bottom of the housing or by similar means to ankle, nail or the like.
  • a frame 1 for a staves bed base engages along its long sides the ends of the staves 3, the aforesaid ends being received in supports 5 which in their turn are arranged and abutted in a split along each side of the frame orthogonal to the moat 3.
  • the various supports 5 joint include both the seats 7 in which are placed the ends 3A of the staves 3 as side housings 9 in the form of axial recesses, which recesses are juxtaposed during the assembly of the various joint supports 5 which are abutted when storing the contiguous moats 3.
  • the joint supports 5 are received in slots 10 generally made by executing a hollow in the tubular profile constituting each side of the frame 1.
  • the housings 9 of the contiguous supports 5 are butted one at the other because of the contact which must be obtained between the various contiguous supports 5.
  • the sum of the lengths of the su p join ports 5 is not perfectly equal to the side of the frame length in which they are received to engage the ends of the moat; in general there is a more or less small clearance and therefore a possibility of slipping, because it is impossible to achieve the precision required for a blocking and on the other hand it is necessary to keep a certain clearance also in order to ensure the assembly various joint supports 5 with the corresponding staves. This movement due to the mounting clearance is avoided by means of the device according to the invention.
  • the device is placed in the two housings 9 juxtaposed with two contiguous joint supports 5 and it is developed with the aim of spacing these supports by forcing them to deviate from the value of the play, indi quée by D in the drawing.
  • This device can be mounted in any position on each side of the chassis orthogonal to the staves and is installed when mounting the supports, between the seats of which the staves are inserted by bending and subsequent straightening.
  • the device is produced by means of a bar 12 which is placed in the housings 9 juxtaposed with two contiguous supports; the length of the bar can be of the order of magnitude of the sum of the depth of the two housings 9.
  • the two supports 5 are blocked in this relative position 5 by using dowels or nails 14 which are driven into the bar 12, through the walls of the housings 9.
  • Both the material of the supports 5 and that of the bar is a plastic material capable of being pierced by these nails or dowels. The nails also pierce the entire thickness of the bar 12 and engage in the two opposite walls of the housing 9, to the right of which the nails are driven.
  • a bar 22, functionally analogous to that 12, is placed in the two housings 9 juxtaposed with two contiguous joint supports 5 for two contiguous staves, between which supports the clearance D must be stabilized.
  • the ba r rette 22 has opposite axial recesses 24 in which two small springs 26 are placed, each of which small springs, once the assembly has been carried out, reacts between the bottom of its recess 24 and the bottom of the housing 9 in which the small spring 26 is square.
  • the two small springs are deformed under compression during assembly, and consequently they ensure an elastic stress of expansion, that is to say of reciprocal distance between the two joint supports 5 between which the bar 22 with the small springs 26 is interposed. Thus the clearance D between these two supports 5 is caught.
  • a bar 32 functionally equivalent to that 22 has a single recess 34 for a single small spring 36 capable of reacting on the bottom of the recess 9 of one of the two sup adjoining ports 5 between which the clearance D must be caught, while the end 32A of the bar rests directly on the bottom of the other housing 9 juxtaposed to the one above and forming part of the contiguous joint support 5.
  • the spacing of value D between the two contiguous supports 5 is obtained elastically.
