Adjustable stand, e.g. for a printing unit

Description

[0001] The invention relates to a stand for carrying an apparatus, e.g. a printing unit, comprising a carrying layer having carrying members for carrying said apparatus, and being supported by means of at least one post on a supporting base, and first and second setting means operating in mutual transverse directions for setting the depth and the width respectively of said carrying layer.

[0002] Such a stand is described in FR-A-2.374.868. This stand comprises a traverse supported by a single post. The first, depth-wise setting means comprise two parallel, spaced tubes which are secured to the traverse, and in which four telescopic rods are arranged. The second width-wise setting means comprise two parallel spaced tubes which are secured to the free ends of the rods and in each of which a telescopic bar is arranged, the free ends of which are provided with a carrying member rigidly secured thereto.

[0003] It is the object of the invention to provide a stand of which the applicability, stability and rigidity are increased. According to the invention the stand is characterized in that the stand comprises two posts; the first setting means comprise two setting members which are secured to the respective post, and two setting pieces slidably connected to the respective setting member; the second setting means are arranged between the two posts; and further third setting means which are pivotable inside said carrying layer are arranged at free ends of the setting members and/ or at the setting pieces.

[0004] By the use of two posts and the arrangement of the second setting means therein between the stability is increased. The specific construction and arrangement of the first and second setting means results in a reduction of the number of setting members and setting pieces. The use of the third setting means the distance between the supporting members can be reduced to a distance which is smaller than the length of the setting members by turning the third setting means towards one another or increased to a larger distance by turning the third setting means in opposite directions. Furthermore it is possible to carry on the stand according to the invention an apparatus of which the distance between the pair of front legs and of the pair of rear legs is different.

[0005] Additionally the carrying layer is as open as possible so that in the case of a printing unit any conflict is avoided with paper to be printed or printed in the printing unit carried by the stand according to the invention.

[0006] When said carrying members having a connecting part of relatively different thicknesses are used a difference in height between various legs of the apparatus to be carried can be corrected in a rather simple manner.

[0007] When said apparatus is a printing unit, and at least one element for carrying paper to be printed and/or printed is disposed between said carrying layer and said supporting base, and on the one hand is connected to the stand and on the other hand bears on the ground, the load of said paper is directed to the ground, so that hardly any deformation forces are exposed to the stand.

[0008] When the carrying layer, the posts, the supporting base, the setting means and/or carrying element are relatively releasable and generally elongated elements, these constituents of the stand can be packed in a dismounted state in a small parcel, which is advantageous for the cost for transport and for stock facilities.

[0009] The above-mentioned and further features will be elucidated with reference to a few non-limitative examples shown in the accompanying drawings.

[0010] The drawings show in:

Fig. 1 a stand embodying the invention carrying an apparatus;

Fig. 2 and 3 each an embodiment of the stand in accordance with the invention;

Fig. 4 and 5 detail IV and detail V respectively of Fig. 2;

Fig. 6 and 7 a detail VI and a detail VII respectively of Fig. 3; and,

Fig. 8 the component elements of the device in the dismounted state in accordance with the invention illustrated in Fig. 2.

[0011] Fig. 1 shows the frame 1 embodying the invention carrying an apparatus 2. The apparatus 2 is a printing unit to which paper 5 is fed from a stock container 3 through the underside 4 and collected on carrying elements 51 after being processed. As is shown in further detail in Fig. 2 the stand 1 comprises a carrying layer 7, which is connected through two posts 8 with a supporting surface 10 bearing on a substrate 9 and formed by two supporting beams 11, 12 provided each with supporting caps 39.

[0012] The stand 1 (Fig. 2) is provided with first setting means 13 and second setting means 14 operating in relatively transverse directions for independently setting the depth d and the width b respectively of the carrying layer 7 consisting of two carrying members 15, 16 spaced apart by a distance b and fastened each to a post 8.

[0013] The first setting means 13 comprise two setting pieces 17, 18, which are slidably arranged parallel to the carrying layer 7 in the setting members 15, 16, whilst with the aid of guard means 19 the setting pieces 17, 18 can be guarded against displacement with respect to the setting members 15,16 concerned. The setting members 15,16 and the setting pieces 17, 18 are each provided with a cylindrical cap 20 or carrying member receiving a leg of the apparatus to be carried.

[0014] The second setting means 14 comprise two transverse members 21, 22 and transverse pieces 23 and 24 respectively slidably arranged in the former. With the aid of further guard means 25 the carrying pieces 23, 24 can be guarded against displacement relative to the transverse members 21, 22 concerned.

[0015] Although it is possible to arrange the second setting means 14 between the two setting members 15, 16 of the carrying layer 7, it is preferred to arrange the second setting means between the two posts 8 because in this way a particularly stable and rugged constructions is obtained.

[0016] With the aid of appropriate fastening means 26 the transverse members 21, 22 and the transverse pieces 23, 24 are releasably fastened to the posts, which are welded to the supporting beams 11 and 12 respectively.

[0017] The caps 20 are pivotally fastened with the aid of third setting means 27 inside the supporting layer 7, whilst they are fastened to the setting members 15, 16 and the setting pieces 17, 18 associated with the carrying layer 7. With the aid of these third setting means the width b can be further reduced, when the edges 28 of the transverse members 21, 22 strike the post 8', by turning the third setting means 27 as far as inside the setting members 15, 16. In this way the stand 1 embodying the invention can also be used for apparatus 2 in which the distance between the supports thereof is smaller than the length 1 of the transverse members 21, 22.

[0018] Fig. 4 shows in further detail the third setting means 27. They comprise a setting member 29, which is fastened with the aid of a screw 30 to the setting pieces 17, 18 and the setting members 15, 16 respectively. By partly loosening the screw 30 from above or if desired from the underside (not shown) it is possible to turn in the direction of the arrow 31 for matching the cap 20 carried by the strip 29 to the posts of the apparatus 2.

[0019] In the stand 1 embodying the invention shown in Fig. 3 the third setting means 27 fastened to the carrying pieces 17, 18 are arranged on a segment 32 rigidly secured to the carrying pieces 17 and 18 respectively and having substantially the same sectional dimensions as the carrying members 15,16.

[0020] By means of such segments 32 a difference in height h can be compensated for (cf. Figs. 5 and 6).

[0021] In the stand 1 according to the invention shown in Fig. 3 the posts 8 are releasably fastened in the supporting beams 11, 12, which is shown in further detail in Fig. 7. The lower end 33 of the post 8 is inserted into the opening 34 in the supporting beam 11, in which it is guarded by means of the guard members 35.

[0022] In the arrangement shown in Figs. 4 and 5, in which the third setting means 27 are directly arranged on the setting pieces 17, 18 caps 20, 20' have to be used whilst the connecting part 36' has a larger thickness as compared with the connecting part 36 to compensate for the difference in height between the surface 37 of the carrying piece 18 and the surface 38 of the carrying member 15.

[0023] When the second setting means 14 are arranged in the carrying layer 7, the third setting means 27 may be fastened to the second setting means 14.

[0024] As is shown in Fig. 8, the stand 1 of Fig. 3 comprises a plurality of relatively releasable, mainly elongate elements forming the carrying layer 7, the posts 8 carrying elements 51 and the supporting surface 10. These mainly elongate elements can be simply packed and stored so that the costs involved can be appreciably reduced.

[0025] As shown in Fig. 1 two paper carrying elements 51 are used for gathering paper printed in the apparatus 2. Each paper carrying element 51 having a hooked part 52, which is hooked on a transverse member 22, 24, an opposed upwardly sloped part 53, and a downwardly sloped part 54 that rests on the substrate 9. Between the parts 52 and 53, is the element 51 even, so that without any conflict the printed paper 5' can be gathered in a zig-zag manner. The whole member 51 is bended out of two separate metal wires which are welded together.
