DE3228046A1 - Elastic sliding roller - Google Patents

Abstract

In an elastic sliding roller, an upper rebate (21) and a lower rebate (22), which are located on a sliding-roller support (2), and a stop (3) are brought into engagement with one another, in order thereby to retract the sliding roller (1) and conceal it in a sliding-roller seat (5) or to extend the sliding-roller support. The roller is very simple to use: the stop (3), when actuated outwards, can separate from the upper rebate and presses the sliding roller into said support, the lower rebate being exactly parallel to the stop which, after release, can take up the lower rebate, so that said roller can be retracted into said seat and concealed there. When the stop is actuated outwards again, the roller can spring out of the seat as a result of the force of the spring, specifically for the purpose of producing an elastic roller. <IMAGE>

Elastic roller

Conventional casters installed at the bottom of a suitcase are rigid and not elastic. An empty one

Carrying a medium-sized suitcase by hand is uncomfortable and ungrateful, because of the exposed castors, which use up packing space and in a loose package result, so that problems arise for both the manufacturer and the user. Furthermore is it is difficult for the user to choose between medium-sized and small suitcases with or without castors.

The invention is intended to address the aforementioned disadvantages the traditional caster. The invention is characterized by the main effect, which consists in moving the castors inside and outside the castor supports according to the actual

Detailed description of the invention:

The invention is described below with reference to the drawings:

According to the illustration in Fig. 1, the invention exists of main elements such as a caster 1, a caster support 2, an "upper rabbet 21" and a lower one Fold 22, a stop 3, a spring 4 and a spring 41 and a roller seat 5, etc. Said stop 3 can be moved back and forth by the force of the spring 41. If there is an outward actuation, the Stop from the upper one located on the castor support Separate the fold in order to press the caster 1 and caster support 2 into the caster seat 5. If then the stop is released, this can lower the fold Occupy 22 so as to bring the caster 1 and the caster support 2 into the caster seat 5.

As shown in FIG. 2, the sliding roller 1 is movably fixed in the sliding roller support 2. If the Stop 3 is actuated to the outside, he can move from Loosen the upper fold 21, presses the roller 1 into the roller seat 5 and occupies the lower fold 22. So the Castor 1 take the castor seat 5. In the event that the. Caster seat 5 is sprung outwards, one only has to press the stop 3 outwards in order to separate it from the lower fold 22. The caster seat 5 can then jump outwards as a result of the force of the spring 4 until the bolt 23 above the upper fold 21 denies Roller seat 5 holds. In the meantime, the pressure of the spring 41 causes the holding of the upper fold 21, which is occupied by the stop 3, by the stop 3, so that the castor 1 is fixed outside the castor seat 5

to arrange. ^:

It can be seen from Fig. 3 that the operation of this invention is very simple. When the caster 1 is in the Roller seat 5 is pressed, a protruding, rhombic corner cushion can be used as a base cushion for the bottom of the case be used.
