    3,376,584 EQUIPMENT FOR THE VENTILATION OF BEDS Maximilian Tobolewski, 25/21 Hainholz, 243 Neustadt, . Holstein, Germany Continuation of application Ser. No. 353,017, Mar. 13, 5 1964, This application June 13,1966, Ser. No. 557,320 8 Claims. (CI. 5—317) ABSTRACT OF THE DISCLOSURE Ventilating device for beds, in the form of a boxshaped insert which laterally overhangs an underlying mattress so as to maintain a space between the mattress and the bed clothes hanging down on both sides of the mattress, the overhanging portion of the insert being slotted or otherwise perforated at the bottom and at the top to facilitate the circulation of air through the insert to an overlying bedsheet. io This application is a continuation of application S.N. 353,017, filed Mar. 13, 1964 and now abandoned. This invention relates to a device for ventilating a bed. In small rooms, especially in one and two-room flats, there is often not room enough for spreading out coverlets and other articles of bedding for the purpose of thorough and sufficient ventilation. There have been proposed racks on which the bedding can be spread out but, since these have to be erected in the rooms and themselves occupy considerable space, they do not provide the solution to the problem. The object of this invention is to provide means for ventilating a bed without it being necessary to move the bedding to a special place or to leave a bed uncovered for a long period. In accordance with the invention, a device for ventilating a bed, which is adapted to be placed between upper and lower parts of a made-up bed with at least a part of the device extending outwardly beyond a boundary of the lower parts of the bed, comprises a flat hollow box with parallel rectangular top and bottom walls joined by end and side walls, with spaced openings to its interior in at least the top and bottom walls. With the aid of this new device, a bed can be made up in the early morning, even with the addition of a day cover, and ventilation can proceed throughout the day. Two embodiments of the invention will now be described, by way of example, with reference to the accompanying diagrammatic drawing wherein:FIGURE 1 represents part of a vertical cross-section of the bed with the ventilating device in place;FIGURE 2 is a plan of the device;FIGURE 3 is a vertical section on the line III__III in FIGURE 2;FIGURE 4 is a plan of another form of the ventilating device;. FIGURE 5 is an end view of the device as viewed from either the top or the bottom of FIGURE 4;and FIGURE 6 is a sectional view drawn to a different scale, on the line VI—VI in FIGURE 4. In FIGURE 1 the ventilating device 1 is shown in position m a made-up bed comprising a bedstead 2, a mattress 3 on a spring base located between the sides 2a of the bedstead and an underlay 4 on which the device is positioned with its sides extending outwardly a little way beyond the sides of the mattress and underlay;the top coverings 5 are placed on the ventilating insert 1. This insert could be placed directly on the mattress 3 with omission of underlay 4. · As shown in FIGURES 2 and 3, the ventilating device 1 is in the form of a flat box, whose major walls, i.e. the 3.376,584 3. The combination defined in claim 1 wherein said perforations are longitudinally extending slots.
  4. 4
    The combination defined in claim 3 wherein said slots are bounded by sets of parallel bars extending along the upper and lower surfaces of said insert.
  5. 5
    The combination defined in claim 4 wherein said bars are of triangular profile with inwardly pointing vertices. .
  6. 6
    The combination defined in claim 4 wherein said insert further comprises a pair of end walls and an intermediate wall extending transversely to said bars and supporting same.
  7. 7
    The combination defined in claim 6 wherein said walls have the shape of I-beams with webs traversed by said bars and with flanges overlying said bars from the outside. 4 .
  8. 8
    The combination defined in claim 4 wherein said bars are tubular.
