SUPPORT WITH CARRIAGE FOR THE GUIDANCE OF LOAD LIKE A BOX OR BASKET

Abstract: A stand with a slider is described. The stand comprises at least one substantially vertical first portion, carrying at least one first guide means (3), provided to guide the slider between a rear stable first position for a load like a box or back, and a front second position from which the load can be released from the slider relatively easily. The first guide means (3) is designed longitudinally, extending from the rear portion of the stand from a relatively low point, to the front portion of the stand at a relatively high point. The stand with a slider is primarily characterized in that the first guide means (3) is designed in such a way, that said relatively low point is located at level with the uppermost portion of the slider, and that the slider at its rear portion above said load, is provided with first guide element (12) cooperating with the first guide means (3). The stand at its front portion is provided with a second guide means (13) for guiding the underside of the slider.

Description: Support with carriage for the guidance of load like a box or basket The present invention relates to a stand with a slider, the stand comprising at least one substantially vertical first portion, carrying at least one first guide means, provided to guide the slider between a rear stable first position for a load like a box or back, and a front second position from which the load can be released from the slider relatively easily, the first guide means being designed longitudinally, extending from the rear portion of the stand from a relatively low point, to the front portion of the stand at a relatively high point Such stands with a slider are known, e g from the Swedish publication for opposition No. 348 361. In this publication a relatively complicated and thus expensive stand is disclosed, that has probably not been used too widely. Other designs are also known, e g from the French Patent FR 1 238 668, but hitherto there has been no stand of the art mentioned introductorily, that shows a simple design, but is yet efficient and safe in handling, and where the slider carries a relatively heavy load in the front position without a need for a strong design of the stand with a slider. The object of the present invention is thus to provide a stand with a slider of the art mentioned introductorily, that shows the advantageous features mentioned above. According to the invention such a stand with a slider is characterized primarily in that the first guide means is designed in such a way, that said relatively low point is located at level with the uppermost portion of the slider, and that the slider at its rear portion above said load, is provided with first guide element cooperating with the first guide means, whilst the stand at its front portion is provided with a second guide means for guiding the underside of the slider. The slider and the guide means can per se be designed in many ways within the scope of the invention, but in one advantageous embodiment the slider is formed with a vertical rear portion and a horizontal underside, the first guide means being formed as a rail, the first guide element formed as a pulley, whilst the second guide means is a horizontal roll. Per se a design is conceivable, where the stand has only one side portion resp there is only one guide means, in this case located above the middle of the slider, but in one suitable embodiment the stand comprises two side portions, each of them provided with first guide means whilst the slider is provided with two corresponding first guide elements. It is not necessary to limit the ability to move of the slider forwards downwards, but it is advantageous to provide cooperating elements at the stand and at the slider, designed to limit said movement in a position, where the slider tilts forwards downwards and where any load like a box or back can easily be removed from the slider. The slider is suitably manufactured from profiles, preferably from aluminum which also may be true for the stand. In one advantageous embodiment the slider is provided, at its rear, lowest portion, with a hinge around which a flap is journalled, against the force of a spring or the like, tumable from a first position in a substantially vertical position, towards the rear portion of a load to a second substantially horizontal position, into which the flap by a stop prevents the load from performing a movement backwards. An example of an embodiment of the invention shall be described more in detail in the following, reference being made to the enclosed schematical figures, of which: figure 1 shows a front view of a stand, with the slider in a rear first postion, figure 2 shows a view in the direction of the arrows in a section marked by A- A in figure 1, figure 3 shows a front view of the stand in figure 1, but with the slider in a second, front position, figure 4 shows a view in the direction of the arrows in a section marked by B-B in figure 3, and figure 5 shows a side view of an alternative embodiment of the slider according to the invention. In the figures 1 and 2 refer to sides of a stand. In the sides there are fixed first guide means 3 resp 4 in the form of U-profiles, provided fixed at a lower point in the rear of the stand and at a higher point at the front of the stand, so that the guide means rise upwards forwards in the stand. A slider consists of a horizontal underside 5,6 and a vertical rear portion 7,8. In the actual case the underside and the rear portion are made from profiles in such a way, that the profile 5 of the underside is connected to the profile 7 of the rear portion by a cross bar 9, and the profile 6 of the underside is connected to the profile 8 of the rear portion by a cross bar 10. Profile parts keep one side 5,7,9 of the slider together with its other side 6,8,10. In the upper part of the rear portion are provided, at each side, a guide element in the form of a pulley 11,12, arranged to run in the corresponding first guide means 3 resp 4, that is to say each of them in a U-profile. Between the sides of the stand there is provided at the front a horizontal shaft 13 with guide wheels 14 and 15 for guiding of the underside of the slider 5,6 that is to say the profiles with these reference numbers.in the front portion of the stand there are stop lugs 16,17 so designed, that they prevent the slider with its cooperating stop lugs 18,19 to move forwards downwards further than to a position, where the load of the slider may easily be removed from the slider. The function of the slider is most easy seen in the figures 2 and 4. In figure 2 the slider is in its first, rear position, and rests stably with its load in this position. If the slider is drawn forwards, the rear portion will be guided forwards upwards and the underside will be guided forwards downwards, so that the slider will tilt forwards downwards. By locating said stop lugs at the slider suitably, the latter will take such a position, without any strong force, that loading and unloading of a box, back or the like will be easy and safe. The slider in figure 5 is in its rear, lowest portion provided with a hinge 20, around which a flap 21 A,B is journalled. It is tumable, against the force of a spring or the like, from a first position 21 A, in a substantially horizontal position towards the rear portion of a load 22, to a second, substantially horizontal position 2 IB, in which position the flap by a stop 23 prevents the load from performing a movement backwards. It is thus possible to draw out the load backwards to a position where it is kept by the flap. If this is pressed down so that the load is released, the load may be lifted out.
