Description:
HOLDING STRIP FOR SUSPENSION BARS

The present invention relates to a holding strip for sus¬ pension bars, which is known and used to suspend various objects, e.g. brackets and shelf units etc, carried by said brackets, the holding strip being designed to be screwed on or in another fashion be fastened, in a hori¬ zontal position, to e.g. a wall and designed with a rear face for contacting said wall and a lower holding edge bent obliquely upwardly and inwardly towards the room and designed to hold a suspension bar, which latter to this end is designed with a slot, designed in a corresponding manner, with which slot said holding edge can engage. When the suspension bar is suspended it is lowered with its suspension slot over the holding edge of the holding strip. Some holding bars are also provided with an upper edge, which is bent obliquely upwardly and inwardly to¬ wards the room and which can form a kind of shade ledge or abut the ceiling. A holding strip having a suspension bar of the known type described above is shown in Fig. 1.

This known type of holding strip has a serious drawback, since the suspension bar can be unhooked from the holding edge of the holding strip, if it is lifted upwardly so far that said slot is disengaged from said holding edge, which may result in that an entire shelf set or the like gets loose and tumbles.

The object of the present invention is to solve this prob¬ lem and suggest a new and improved holding strip, which is designed in such a manner that a suspension bar adapted to said holding strip cannot be loosened inadvertently, because said suspension bar is in its normal mounting po¬ sition secured against at least such large lifting move¬ ments that would loosen it from the holding edge of the holding strip, while it in one or several positions yet can be adapted onto the holding edge of the holding strip and loosened from it respectively.

Said suspension bar comprises, according to the present invention, a rear face in a known fashion used to screw the suspension bar to a wall or the like, and a lower holding edge bent obliquely upwardly and inwardly towards the room, on which holding edge the suspension bar, pro¬ vided with a obliquely upwardly and inwardly directed mounting slot, can be hooked, and the novel feature of the invention is that said suspension bar is designed with an upper edge, which is bent obliquely downwardly and inwardly towards the room and is used as a stop edge, which prevents a removing of said suspension bar from the holding edge of said holding strip, said upper edge of said holding strip in one or several areas being cut away up to said rear face a distance which corresponds to the width of said suspension bar, thus allowing the latter to be hooked downwardly over said holding edge solely in this or these areas and subsequently be pushed in a late¬ ral direction, sliding with its suspension slot along said holding edge into the desired position on said hol¬ ding strip. An optional number of suspension bars can in this manner be adapted to just one holding strip.

Additional characterizing features and advantages of the present invention will be set forth in the following de¬ tailed description, reference being made to the accompa¬ nying drawings.

In Fig. 1 in the drawings a holding strip of a type al¬ ready known is shown. In Fig. 2 a holding strip according to the present invention having two different types of suspension bars in mounted positions is shown in a per¬ spective view. Fig. 3 shows a cross-section of the bar according to the invention with a suspension strip ready to be mounted. Fig. 4 shows in a corresponding way the sus¬ pension bar in a completely mounted and loaded position on the holding strip. Fig. 5 shows also in the same way

the suspension bar in a situation when it is being pushed past a round head of a screw, by means of which the hol¬ ding strip has been screwed onto the wall; and Fig. 6 finally shows a holding strip provided with a cover or barrier strip according to the present invention.

The holding strip comprises a longitudinal bar, which can be produced in endless lengths and be cut to the desired lengths and comprises a rear face 1, a holding edge 2 bent upwardly from the lower edge of said rear face and designed to hold a suspension bar and a stop edge 3 bent downwardly from said rear face and designed to prevent an inadvertent loosening of a mounted suspension bar.

Said rear face 1 is even and designed to be screwed or in an another way fastened to a wall or another vertical surface and to this end it is provided with screw holes 4 for screws 5, suitably having round heads, in order to obtain a better strength.

Holding edge 2 is bent upwardly and inwardly towards the rroooomm aatt aa cceerrttaaiinn aannggllee,, ee..gg.. aann aaingle of 30 , in relation to a vertical plane, e.g. the wall,

Said stop edge 3 is bent from the upper edge of rear face 1 obliquely downwardly and inwardly towards the room, and thus it forms an acute angle with the wall or a vertical plane, e.g. an angle of about 30°. This angle is less critical. The outer end of the stop edge suitably is bent upwards and thus it forms a horizontal plane or a curve, against which a suspension bar abuts and is stopped, if the holding bar is lifted upwards. In one or several areas the stop edge has a recess up to rear face 1, one or se¬ veral adjustment grooves 7 being formed having such a length that a suspension bar can be introduced in it and subsequently be lowered, said suspension slot engaging

holding edge 2 of the strip.

Suspension bar 8 is known per se and comprises an essen¬ tially U-shaped profile, which along its web portion is provided with one or two series of slots 9, designed to receive shelf brackets (not shown) or the like and which adjacent its upper edge is designed with a mounting slot 10, which extends into the legs of the U-profile from those edges of said legs which abut said wall and oblique¬ ly upwardly and inwardly towards the room, said mounting slot having the same direction as the holding edge and essentially the same length. The suspension bar is adap¬ ted to the holding strip in such a way that the distance between the inner and upper end of mounting slot 10 and upper edge 11 of suspension bar 8 is not larger than the free vertical distance between holding edge 2 and stop edge 3.

However, in a preferred embodiment of the invention the distance between the inner and upper end of mounting slot 10 and upper side 11 of suspension bar 8 is somewhat smal¬ ler than the free distance between holding edge 2 and stop edge 3 of the holding strip, and in this way suspension bar can be lifted such a distance, obliquely upwardly and inwardly towards the room, that it can be pushed past the round head 5 of a screw without disengaging it from hol¬ ding edge 2 of the holding strip, which is shown in Fig.4.

The mounting of a suspension bar is accomplished by moving the bar towards the holding strip at an adjustment groove 7 and lowering it in order to make holding edge 2 slide into mounting slot 10 of the suspension bar, subsequent to which the suspension bar is moved in a lateral direc- tion from adjustment groove 7 to the desired position, where it will be secured against a loosening from the hol¬ ding strip by means of stop edge 3 of the holding strip.

A suspension bar can be lifted up and released in the opposite manner, provided the bar is moved to an adjust¬ ment groove 7.

In order to cover the front of the used holding strip or a portion of it a cover strip 12 can be introduced into the groove between holding edge 2 and stop edge 3, the covering strip together with the holding strip forming a neat unit. Also, suitable lengths of the cover strip can be used to prevent suspension bars from moving in a late¬ ral direction or in relation to a side wall, such pieces of material being introduced between holding edge 2 and stop edge 3 and engaging the outer sides of the legs of said suspension bar.
