Display stand

Abstract: The invention relates to a display stand, e.g. for clothes, comprising an adjusting tube (1) arranged slidably in a frame tube (1a) and to which adjusting tube is connectable a display part (14) for carrying clothes etc. An object is to provide a new display stand or the like, with a step-wise height adjusting of the adjusting tube in relation to the frame tube, for reliable locking and easy handling. The wall of the frame tube (1a) has apertures at certain distance vertically; the lower part of the adjustment tube (1) is provided with a turnable locking element (2), which in locking position extends through an aperture (16) made in the wall of the adjustment tube (1) and through an aperture (15) made in the wall of the frame tube, respectively, and the upper part of the adjusting tube (1) is provided with an arm (9) which interacts with the locking element (2) for turning this from locking position to a position inside the adjusting tube.

Description: The present invention relates to a display stand, e.g. for clothes, which comprises an adjusting tube arranged slidably in a frame tube and to which adjusting tube is connectable a display part for carrying clothes etc. The height position of the display part is adjustable by moving the adjusting tube in relation to the frame tube. For locking the tubes to each other into desired position, different kinds of friction locking means have often been used, such as friction plates or friction rolls, which have the disadvantage that they have not remained in place when under load. Mechanical adjustment means of step-wise function have also been used. In document GB-A-2 194 435 an adjustable height display stand is disclosed, comprising a base unit supporting an upper unit on which items may be displaced, the upper unit being movable relative to the base unit and fixable in one of a number of predetermind positions relative to the base unit by operation of a latch. This turnable latch is positioned in the lower part of the adjustment tube, and extends through an aperture in the wall of the adjustment tube, as well as through an aperture in the wall of a frame tube in locking position. Furthermore, an arm which interacts with the latch for turning this from locking position to unlocked position is positioned in the upper part of the adjusting tube. What has to be seen as a serious drawback with the arrangement disclosed in the above cited document is the fact that the whole mechanism for locking the stand in different heights is extremely unreliable due to its mechanical simplicity. Furthermore, document US-A-2 921 763 discloses a clothes stand that can be collapsed, the parts being folded up to occupy a small space only. The height adjustment of the arrangement disclosed in this document, although providing step-wise adjustability, is unconvenient and difficult to use. It is an object of the invention to provide a near display stand or the like, with a step-wise height adjusting of the adjusting tube in relation to the frame tube, for reliable locking and easy handling. This object is achieved by means of the display stand according to the present invention provided with an arm that interacts with a locking element for turning the latter from the locking position to a position inside the adjusting tube, mainly characterized in that said arm is connected to a slide gliding inside the adjusting tube, a spring is arranged above the slide, and above the spring, in abutting connection, is provided a mounting part, for the display part, provided with a receiving aperture for the display part and a bolt for locking the display part in place, wherein the spring ensures the return movement of the slide and thus the turning of the locking element into locking position when the adjusting tube is in desired height position in relation to the frame tube. Thus a new, reliable connection for the display part mountable to the adjusting tube, which does not require welding and which in an easy way makes variations possible to meet a client's desire. Preferred embodiments of the invention are defined in the dependent claims 2 to 5. In the following the invention will be described with reference to a preferred embodiment, by way of example, shown in the attached drawing. Figure 1 shows a display stand seen in perspective. Figures 2 and 3 show partial sections of the adjustment tube, including locking means. Figure 4 shows a section along line A-A in figure 3. Figure 5 shows the locking and mounting means in an exploded view. Figure 6 illustrates the function of the locking element. Figures 7 and 8 illustrate fastening of a display part to the adjusting tube. Figure 1 shows a double stand wherein two adjusting tubes 1 are arranged slidably into a respective frame tube 1a supported by a base. The adjusting tube slides inside the frame tube guided by a sleeve 8 and by protrudings in the lower part. A display part 14 is mounted to the upper part of the adjustment tube. Of the interlocking arrangement for the adjusting tube and the frame tube, an adjusting arm 9 and apertures 15 made in the frame tube wall are visible in figure 1. The structure and the function of the locking arrangement appear from figures 2-6. Reference numeral 2 designates a latch-like locking element, 3 designates a lifting wire connected to the locking element 2, 4 designates a slide connected to the upper end of the lifting wire 3, sais slide being arranged inside the adjusting tube and being, preferably, made of plastics material, 5 designates a spring cotter pin fastened to the slide 4, 6 designates a nut, 7 designates a rivet acting as a support and turning axle for the locking element 2, 8 designates a guide sleeve for the adjusting tube, 9 designates an adjusting arm, 10 designates a bolt for fastening, together with the nut 6, the adjusting arm 9 to the slide 4, 11 designates a spring, 12 designates a tube fastener and 13 designates a retaining bolt. For adjustment in height, the adjusting arm 9 is moved upwards, whereat the locking element 2, through interaction by the slide 4, the spring cotter pin 5 and the lifting wire 3, turns from the locking position of figure 2 to the freeing position of figure 6 (locking element 2 inclined), where the locking element is within the frame tube and whereat the adjusting tube is freely movable in the vertical direction. After choosing the desired height, the adjusting arm is released, whereat the spring 11 ensures downward movement of the slide 4 and the locking element 2 turns into original position. In this position, the point of the locking element extends out through a respective adjusting aperture in the frame tube 1a and locks the adjusting tube 1 reliably in place in support by the upper edge of an aperture 16 in the wall of the adjusting tube. In a side of the upper part of the adjusting tube is formed an aperture, which permits different display parts 14 to be mounted by means of a tube fastener element 12 and a retaining bolt 13. In addition, the threaded aperture of the tube fastener element 12 is long enough to permit mounting of a poster arm or the like.

Claims: A display stand, e.g. for clothes, which comprises an adjusting tube (1) arranged slidably in a frame tube (1a) and to which adjusting tube is connectable a display part for carrying clothes etc., in which stand the lower part of the adjusting tube (1) is provided with a turnable locking element (2) which in locking position extends through an aperture (16) made in the wall of the adjusting tube (1) and through an aperture (15) made in the wall of the frame tube (1a), respectively, and the upper part of the adjusting tube (1) is provided with an arm (9) which interacts with the locking element (2) for turning this from locking position to a position inside the adjusting tube (1), characterized in that said arm (9) is connected to a slide (4) gliding inside the adjusting tube, a spring (11) is arranged above the slide (4), and above the spring (11) in abutting connection, is provided a mounting part (12) for the display part (14), provided with a receiving aperture for the display part and a bolt (13) for locking the display part (14) in place, wherein the spring (11) ensures the return movement of the slide (4) and thus the turning of the locking element (2) into locking position when the adjusting tube (1) is in desired height position in relation to the frame tube (1a). A display stand according to claim 1, wherein the slide (4) is connected to the locking element by means of a stiff lifting wire (3).
