DE3031061A1 - Collapsible cot with telescopic legs - has concertina type folding sides bringing two ends together for easy packing - Google Patents

Abstract

Each corner upright (4) is designed to hold a telescopically extending leg (5) which can be locked in the extended position of use and in the retracted rest position by a clamp mechanism. The two side walls are designed as rectangular sections (7) whose dimensions in the longitudinal direction of the bed are not longer than the width of an end wall. The sections (7) are connected together and to the corner uprights so that they can be turned about their vertical rotary axes for easy folding. The end and side walls are locked in their unfolded position of use by a section clamping mechanism (9) which is released when the bed is folded down. When the cot folds down the side walls fold in such a way that the end walls move towards each other.

Description

Collapsible bed

The invention relates to a collapsible bed, e.g.

for children, with a pair of end walls, four upright corner posts and side walls.

There are currently two main types of collapsible Children's beds offered on the market: on the one hand, such conventional construction, on the other hand, more modern constructions, which have a floor and a right-angled metal frame have, to which a linen or textile covering is attached.

The main advantage over conventional cot designs the more modern construction methods with textile covering lies in the fact that the side and end walls are connected by legs that face the bed across from it Raise the standing level. Therefore, an adult does not need to bend down when he wants to reach into the cot.

Other advantages of conventional designs are that they generally have a firm, flat base so that they are unobstructed Allow air to circulate and that the interior of the cot is easily removed from the Page is visible.

In contrast, have more modern, textile-covered children's bed constructions the advantage of being more compact when folded, as it has no legs from Have substantial length by which the cot is raised above the standing level would be. Another advantage is the low weight of such beds.

With conventional collapsible cots, two can usually be Types are differentiated: 1. The bed is folded along a diagonal axis, whereby the end walls together with the attached legs are brought together. This creates a relatively compact bed, the maximum dimensions of which by the End walls and the length of the legs are determined, but can be folded up such a bed can be relatively difficult.

2. The bed is collapsed along a transverse axis so that the two side walls together with the attached legs are moved towards each other. The result is a relatively bulky folded bed, its maximum dimensions by the The size of the side walls and the attached legs is determined, but is one The bed is relatively easy to fold.

The invention is based on the object of a collapsible bed such as creating a crib that retains the benefits of traditional construction and also the compact form of modern, textile-covered constructions having. The advantage of the beds according to the invention over others on the market available products of this type is, among other things, that the folded Bed fits easily in the trunk of a medium-sized automobile and that it is light can be stored on a shelf.

Another object of the invention is to provide a wood, metal, To create a bed made of plastic or another suitable material, which can be folded in such a way that the two end walls can easily be moved towards one another are.

Furthermore, the side walls of the collapsible bed in the Be variable in height, so that access to the interior of the bed is facilitated.

According to the invention this object is achieved in that each corner post receives a telescopically extendable leg, which by means of a first clamping device in the extended position of use or in the pushed-in non-use position is locked; that a pair of side walls made up of several rectangular sections exists whose dimension in the longitudinal direction of the bed is no longer than the width of a Front wall, the rectangular sections to each other or to the corner post around essentially vertical axes of rotation are articulated; that second clamping devices lock the side and end walls in the extended position of use, with the clamping devices solved when folding the bed and the end walls are moved towards one another while folding the side walls.

Another preferred embodiment of the invention provides that the longitudinal dimension of each rectangular section of the side walls is no longer than half the width of an end wall and that the side walls when collapsing folded like an accordion.

Furthermore, a floor is provided between the walls, the several Has floor panels, the ends of which are each at the lower portion of the adjacent End wall around substantially horizontal transverse to the longitudinal direction of the bed Axles are articulated, with the floor panels supported on arms in the position of use which are attached in the lower area of the side walls and which are placed in this way are that they do not prevent the bed from collapsing, while the dimensions the floor panels in the longitudinal direction of the bed are no longer than the height of the end walls, so that when folding the bed, the floor panels in the longitudinal direction of the bed End walls can be folded and after releasing the second clamping devices the end walls are pushed towards one another while folding the side walls.

Preferred embodiments of the base plates and the side walls of the bed are described in the claims.

The following description is based on an exemplary embodiment the drawing explained in detail. Thereby shows or show: FIG. 1 an overall view a bed according to the invention in the unfolded state; Fig. 2 and 3 show the bed of FIG. 1 in a partially or fully collapsed state; Fig. 4 shows details of the arms by means of which the bottom on the side portions of the Bed is attached; Fig. 5 shows details of a telescopic corner post Wood; Fig. 6 shows details of a corner post made of aluminum or other suitable material is made and Figs. 7 and 8 details of a telescopic Side wall in raised or lowered position.

Fig. 1 shows a bed in an unfolded state.

In the end walls of the bed, the upper wall parapet 1 is through a Number of struts 3 connected to the lower wall parapet 2. On every front wall Attached to the bed is a pair of upright hollow corner posts 4, one of which each telescopically accommodates a leg 5 which, in use, is pulled out downward and is locked by means of a clamping device 6. The side walls of the bed consist of four sections 7, which are attached to each other or to the adjacent corner posts at the level of the upper and lower parapets 2, 3 by means of a number of hinges 8 are hinged. The sections 7 of the side walls are by means of the upper parapet Clamping devices such as pawls 9 are fastened together, the pawls 9 the hinges 8 are opposite. The floor panels 10 are hinged 11 hinged to adjacent end walls and are attached to the lower side wall Parapet attached arms supported.

In Figures 2 and 3, the bed is in partially and fully collapsed, respectively Condition shown. The floor panels 10 are lifted off the supporting arms 12 and folded up towards the adjacent end walls.

As soon as the base plate 10 is essentially parallel to the end wall , it is fastened by means of a clamp 13. The pawls 9 are then released and the two end walls are moved towards each other like an accordion »A belt 14 then connects the two end walls and also serves as a handle. The legs are telescoped into the corner posts and locked in place.

Fig. 4 shows in detail how by means of the arms 12 the lower side wall Parapet is attached to the floor panels 10, with a pin 15 in a journal bearing 16 is introduced.

Two types of corner posts are shown in Figures 5 and 6, as the case may be whether wood, metal or another suitable material is used.

7 and 8 details of a bed are shown with Side walls is provided by a telescopic movement of one or more Upright components 17 can be lowered, with clamping devices 18 the side wall Hold in raised or lowered position. When changing the height of the side wall the upper side wall parapet moves along the rails 19.

The in the above description, the drawings and in the Features of the invention disclosed claims can both individually and in any combination for the implementation of the invention in its various Embodiments are essential.
