fig1 - 5 show a mounting bracket 1 comprising a mounting plate 4 and a base plate 3 . slat connectors 5 are mounted on the base plate 3 and a bearing stub 2 that is insertable into a recess that is provided on the frame of the slatted base ( not shown ) is provided on the mounting plate 4 . when the mounting bracket 1 is fitted onto the slatted base frame , the base plate 3 then lies on the top surface of the base frame . it is understood that the construction of the mounting bracket 1 may have to be adapted to the slatted base frame , depending on the particular construction of the slatted base frame . so , for example , instead of the bearing stub 2 that is shown in the figures , differently constructed fastening means may be provided . it may also be possible to eliminate the connecting plate 4 , if , for example , the mounting bracket 1 is to be fastened directly to the top side of the base frame . in that case , a bearing stub constructed similarly to the bearing stub 2 may be provided on the underside of the base plate 3 , so that it extends downward from the base plate 3 . two plugs 5 are arranged on the base plate 3 . these plugs 5 extend upward from respective plug bases 6 that are mounted or formed on the base plate 3 . the plug bases 6 serve to optimally support the plug 5 against shear forces . a rib 7 is provided on an upper area of the plug 5 , on the long side , so that the plug 5 has a comparatively wide head region , to provide a forced fit in the spring slat , to secure it against forces working to lift the slat off the plug . the material for the plug 5 has a certain elasticity , which enables it to be insertable through a plug opening in the spring slat that is narrower than the head region on the plug . in the shown embodiment , the mounting bracket 1 is as a single injection - molded plastic piece . thus , the head region with the ribs 7 , the entire plug 5 including the socket 6 , and the entire mounting bracket 1 are made of the same material . alternatively , however , the mounting bracket 1 may be produced in a well - known manner using the so - called two - component or multi - component injection molding . in this case , the mounting bracket 1 may have rigid and flexible regions made of two or more different materials , so that the head region with the ribs 7 , for example , may be made to be more flexible than the socket 6 . the plugs 5 may also be constructed in a way that deviates from the shown embodiment . for example , the plug 5 may have a round cross section instead of an oblong one , and two or more plugs may be arranged in a row , that is , one behind the other in the longitudinal direction of the spring slat that is to be secured . fig2 and 3 are top and bottom views , respectively , that show a spring slat 8 fastened to the mounting bracket 1 . the two plugs 5 extend into two oblong plug openings 9 of the spring slat 8 that are constructed as slots 10 . the bottom view shows that the plug openings 9 on the bottom side of the spring slat 8 widen into a larger cross section that is adapted to the measurements of the sockets 6 , so that the sockets 6 are received into these wider cross - sectional areas . one also sees that the two plug openings 9 , including the expanded cross - sectional areas , extend beyond the plugs 5 in the direction of the end of the spring slat 8 . this allows a relative movability between the spring slat 8 and the mounting bracket 1 , so that it is possible to guide the end of the spring slat 8 closer to the mounting bracket 1 . further movement of the spring slat 8 in relation to the mounting bracket 1 is not possible , however , in the opposite direction . the expanded lower cross sections of the plug openings 9 are limited in length and are shorter than the aforementioned slots 10 , so that they create a stop that limits further movement plug bases 6 when the spring slat 8 is moved relative to the mounting bracket 1 in such a direction that the gap between the end of the spring slat 8 that is visible in the drawings and the mounting bracket 1 increases . these ends of the expanded cross - sectional areas of the plug openings 9 , which form the stop , are hidden from view in fig3 by the mounting bracket 1 . fig4 shows that the plug openings 9 are constructed as a part of longer ventilation slots 10 and that the plug bases 6 have a rounded contour on the side that faces the end of the spring slat 8 , and a straight contour on the opposite end that faces toward the middle of the spring slat 8 . fig5 is a bottom plan view that shows the contours of the plug openings 9 that are expanded on the bottom side , these openings 9 being adapted to the dimensions of the sockets 6 .
a bracket and spring slat for a slatted bed frame . the bracket has plugs that extend into slots on the spring slat and also a bearing stub that is insertable into a recess on the frame . the slots accommodate a spring action of the slats . the bracket and spring slat combination allow slats to be placed very close together in areas of heavy loading .
