Definitions
- the subject matter of the invention is a self- adapting lath bottom for example for beds and chairs, said lath bottom having at least two frame beams, to which are attached with bearings rope sheaves over which run ropes supporting, with the help of other rope sheaves and support members, laths connected with one another.
- the bottom structure of a bed and seat utilizing a lath bottom with rope sheaves is previously known from the PCT publication 83/01563 and references cited therein, in which is illustrated the operating principle of the lath bottom with rope sheaves.
- the use of the already described lath bottom with rope sheaves has been limited by its frame structure, especially in double beds and seats, as the laths are attached by their ends via rope sheaves in between the frame structure, leading in practical use to a situation where, when the laths are depressed to the space between the frame beams, the top edge of the frame remains at an uncomfortably high level especially at those points where the depression is substantial.
- the frame structure constitutes an uncomfortable ridge between the users.
- the ridge may be located at different positions depending on the measurements of the users.
- the inconvenience caused by the frame structure can be alleviated by covering the frame with a soft material or by strengthening the softening part on top of the laths.
- a lath bottom in accordance with the U.S. Publication 3717376, Figure 9 is perhaps closest to the present invention.
- the attachment of the pulley and cord apparatus to the frame poses a problem.
- the support of the lath bottom by the cord pulleys is unstable. Additional problems may be caused by the accumulation of impurities.
- a structural solution in accordance with the present invention solves the above-mentioned problems and gives a more practical form to the lath bottom, improves the ventilation of the bed, as the softening part can be made less thick and realized on a lath- per-lath basis. Additionally, it is intended that the structure of the lath bottom be made solid and in such a way that it functions without interference.
- the mode of operation in accordance with Claim 3 renders the use of bearings reliable and inexpensive from a manufacturing point of view. Moreover, the V- shaped gliding surfaces guarantee an operation without interference.
- FIG. 1 General structure of the lath bottom bed in accordance with the invention, shown from top, side and front.
- Figure 2 Side view and partial cross-section of the frame beam and positioning of rope sheaves for the laths.
- Figure 3 Cross-sectional view of the frame beam.
- Figure 4 and 5 Side view, partially cross-sectional, of the lath and support member.
- Figures 6 and 7 Partly cross-sectional front view of lath and support member.
- Figure 8 Slide attachment of the supporting member to the link in the lath.
- the lath bottom with ropes consists of two support beams 1 , which are attached via the fastening piece 7 to the end plate 8, which has the fastening and adjustment comb 9 for the rope 4.
- the end plate 8 is used to attach the lath bottom to the frame structure of the bed.
- the laths 2 attached to the lath rope sheaves are tied to one another with the flexible band 6 at the attachment point of the lath 2, ie. at the point of the support beams 1.
- the distance of the support beams 1 from one another is smaller than the length of the laths 2.
- the lath bottom adjusts itself via the combined effects of the rope sheaf system 3, 4, 5 and the band 6.
- the laths 2 are tied with one another using the flexible connecting band 6 so as to leave the flexible connecting band somewhat loosely between the laths 2, the self-adaptation of the laths 2 takes place as follows.
- the flexible connecting band 6 pulls the adjacent laths 2 downwards while simultaneously tilting them. This prevents the rope 4 from exercising an elevating effect on the adjacent lath 2 in excess of what the flexible connecting band 6 allows for, transferring its elevating effect on the further laths 2.
- the lath bottom adjusts flexibly.
- the connecting band 6 is only slightly wider than the frame beam 1 , which means that it protects the parts inside the frame beam 1 from impurities yet maintains fully the free ventilation of the lath bottom.
- the support beam 1 can be constructed, as shown in Fig. 2 and 3, with two frame plates 13, or with three frame plates. With an increase in the number of laths, the laths become correspondingly narrower and the lath bottom adjusts better.
- a three-plate construction can be realized such that support members in the same row support every other lath and the laths in between are supported by the adjacent row of support members installed between the frame plates. For the support rope sheaves, there remains the space, amounting to the length of a lath, between the frame plates, meaning that double the number of narrower laths can be accommodated as compared to a two-plate structure using an identically sized rope sheaf apparatus.
- Fig. 2 and 3 show the structure of the lath rope sheaf 5 and of the support rope sheaf 3 and their installation in the support beam 1 , and the attachment of the flexible band 6 to the lath 2.
- the support member 14 consists of two support plates 14.
- the rope sheaf 5 is attached with a bearing to the bottom part of the space between the support plates 15, the top part featuring a bearing-attached swing hinge.
- the rope sheaf 5 and the swing hinge 17 are attached via the bearing tubes 21 and the screws 19 to the support plates 14 such that the length of
- the bearing tube 21 determines the distance between the support plates 14 when they are pressed against the ends of the bearing tube 21.
- the attachment of the lath 2 to the swing hinge 17 is explained below.
- the intermediate piece 12 is a one-piece part and the support rope sheaf 3 is directly attached to 5 it via a bearing. Assembly of the frame beam 1 is thereby realized quickly by inserting pre-assembled intermediate pieces 12 with their attachment pins 20 and support members 14, one after the other, on the frame plate 13 and by threading the rope 4 via the sheaves 3 and 5 the total length of the frame beam 1.
- the steel wire 10 is additionally threaded through all the support members 14 and attached " to the intermediate pieces 12. This done, the other frame plate 13 is positioned on top of the assembled structure, meaning that the pins 20 attach the frame plates 13 to one another.
- the method of assembly may differ from the one described in numerous ways.
- the ease of transportation of the bed or chair as a whole and its easy assembly are largely based o ' n the existence and use of the sliding attachment 15.
- the laths 2 tied with the band 6 constitute a lath carpet which can be rolled up and easily packaged.
- the other parts are the frame beams 1 and the end parts 8 and possibly the additional parts of the frame structure.
- the frame beams 1 are pre-assembled such that they contain the rope sheaves and the support member 14. Assembly is carried out by insertion of each of the sliding plates 16 of the attachment members 14 of each frame beam 1 into the link 18 of the corresponding lath 2. This done, the frame beams ' 1 can be joined with the help of the end plates 8 or some other frame structure.
- the back plate 22 in the link 18 prevents the laths 2 from escaping from their position on top of the frame beams 1.
- the slide structure can be realized in other ways as well, the most important consideration being that it exists.
