BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a stand with a slider. The stand includes 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 basket, and a front second position from which the load can be released from the slider relatively easily. The first guide means extends longitudinally from the rear portion of the stand from a relatively low point, to the front portion of the stand at a relatively high point.
BACKGROUND OF THE INVENTION
Stands with sliders are known in the prior art. For example, Swedish publication for opposition No. 348,361 discloses a relatively complicated and thus expensive stand which, due to its complexity has probably not been used too widely.
Other designs are also known, such as French Patent FR 1 238 668. But hitherto, there has been no stand of the prior art which discloses a simple design which is efficient and safe in handling a load. Moreover, in the prior art, no design has been provided where the slider carries a relatively heavy load in a front position without requiring a strong stand design.
SUMMARY OF THE INVENTION
One object of the present invention is to provide a stand with a slider which provides the advantageous features mentioned as lacking in the prior art discussed above.
According to the invention, such a stand with a slider is characterized primarily in that a first guide means is provided in such a way that a relatively low point is located level with the uppermost portion of the slider. In addition, the slider, at its rear portion above the load, is provided with a first guide element cooperating with the first guide means. 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 of the present invention may be designed in many ways within the spirit and scope of the present invention. In one advantageous embodiment, the slider is formed with a vertical rear portion and a horizontal underside. A first guide means may be formed as a rail. The first guide element may be formed as a pulley while the second guide means may comprise a horizontal roller.
Other embodiments may be employed within the spirit and scope of the present invention. For example, a design is conceivable where the stand has only one side portion with respect to only one guide means. In such a case, the guide means may be located above the middle of the slider.
In another suitable embodiment, the stand may comprise two side portions, each of them provided with first guide means while the slider is provided with two corresponding first guide elements.
It may not be necessary to limit the ability to move the slider forwards and downwards, but it may be advantageous to provide cooperating elements at the stand and at the slider to limit movement to a position where the slider tilts forwards and downwards where any load like a box or basket can be easily removed from the slider.
The slider and stand may be suitably manufactured from extrusions preferably from aluminum.
In another advantageous embodiment, the slider may be provided, at its rearmost lowest position with a hinge around which a flap is joined. The flap may act against the force of a spring or the like. The flap may be rotatable from a first, substantially vertical position towards the rear portion of a load, to a second, substantially horizontal position, in which the flap, by means of a stop, prevents the load from moving backwards.
