¹¹ COMPLETE CHILDREN'S CHAIR "

The invention relates to a children's chair of the so-called type collapsible, victitige and new structural improvements introduces, with the purpose of making the chair very easy to use from collapsed to undressed bringan, being very strong in the extended or in use position and takes up minimal space when folded.

Accordingly, the proposed chair basically consists of two side, rigid frames, between which the seat and the foot support are, made of equally rigid plates, which are in the middle and on the side connections to the frame with Hinges are provided.

On the other hand, »said frames are marked by two stucks connected to each other, so that in the described arrangement of the seat and the footrest allows the chair to be merged is made by bringing both frames together while folding the seat and the footrest together, with which the whole frame is completely merged.

Furthermore, each side frame bears one of the hypothetical ones Diagonal a profile for the inclusion of a 3 iron band, which on the lower end forms a stop, while above with the chair handle connected is.

In the folded position of the chair, both iron straps recorded within the profiles. On the other hand, they become somewhat elastic when they are moved apart or in use Bend pulled out, which compensates for the increased distance between the two stiff side frames.

It must be pointed out that the iron bands must remain outside due to the bending that has been experienced, without the possibility of doing so to get into the profile as long as the chair is not folded up.

Furthermore, in connection with the central shareholder system Seat should be highlighted that a connecting strap is attached in such a way is that you can use it to make a pull to put that together? initiate folding of the seat and the footrest. Because this strap

protrudes when the chair is folded, the chair may be transported to be adhered to.

In order to better understand the essence of the invention, reference is made to the attached Draft the preferred form of completion (only srklärendej wise and in no way restrictive), refer to the description of the draft is referred to.

The purpose of the invention is the construction of a children's chair of the so-called collapsible type consisting of rigid side frames (12) of rectangular shape with the associated pair of wheels at the lower end (see Figure U).

The seat structure spreads out between these side frames (12) (15) as well as that of the footrest (2) transversely, which respectively, as can be seen in Figure 5, made of stiff, thin plate exist and are provided with hinges in the middle and on the sides.

80981 A / 0607

Likewise, two run crosswise between the side frames (12) hingedly connected sloping strips (10) and (20) each one of which at the lower end with the upright longitudinal beams (19) the side frame (12) is articulated. The side members (19) consist of profiles with a U-cross section of one branch is bent inwards (see Figure 9)

The upper 2nds of the sloping strips (1O) and (2ü) are inside the longitudinal beam (I9) is stored, see Figure 3 »and can use the Slide along the side member.

The middle joint axis of the rear sloping line (2θ) goes through a slot on an upright plate (18), which is connected at the upper end to the central hinge of the seat (15) (see Figure 8).

Likewise, on the front of the chair (see Figure 2) is a another board (11) attached, which above with the middle Scharnisr of the seat (I5) is connected, a kink in the middle forms to go past the front sloping strip (1O) and at the lower end »connected to the middle hinge of the footrest (2) is.

Both board (ii) and (18) 3xnd at the top by a strap (8) connected to each other, which when the chair is pulled out on the The seat cushion stays in place (15)

On the other hand, the hypothetical diagonal * runs individual Seitanrahmen (12) with an extended profile (14) U-section, both sides of which are bent inwards, like can be seen from Figure 7.

Each profile (1 ^) acts as a support and guide for an elongated iron band (**) ♦ ^{which is} connected to a handle (5) at the upper end and a stop (16) at the lower end which, in conjunction with a clamp (17 ) around the profile (1 * 0 making it difficult to pull out the iron band (k) (see Figure 6).

The corresponding canvas or the like hangs from the handle (5) forms both the headrest and the back of the chair, which with (6) marked on Figure 2.

On the other hand, on figure h and 5 on one of the chair

* 27-1543

rahinen a * device in the form of an inverted "Y" (13) recognizable, which when turning over the bridge your arms up to the direct The stop against the wheels spreads and thus forms the braking device of the chair.

After considering the nature of the basic components of the proposed chair ^ the behavior of the same can be explained will. To do this, start with the chair position shown on the first sheet of the attached tarpaulin To put the chair together, it is sufficient to pull on the straps (8) so that the folding of the seat (15) and the footrest (2) is initiated.

When this initial collapse takes place, the side frames (12) come closer together, with the elastic nature of the iron straps (h) contributing. During this collapse, the inclined strips (ΐθ) and (2θ) rotate around their lower joints while the upper ends slide along the profiles (19).

When the ssitan frames (12) are brought together tightly, you can hide the iron straps (k) within the profiles (14) by pressing the handle (5), whereupon the chair is completely folded with minimal space requirements, as in the Figures 10 and 11 of the attached plans will appear.

It should be noted that the belt (8) in this position is over both side frames (12) protrudes and serves as a handle for transporting the folded chair.

The spreading of the chair is also carried out in reverse, because the iron bands (4) separate the side frames (12) as long as they are not pulled out.

It should also be noted that the nature of the iron bands (4) their appropriate elastic deformation allows the compensates for the increasing separation of their lower ends as the chair transitions from the collapsed to the spread position.

Likewise, the elastic deformation of the iron blinders (k) in the unfolded chair determines their firm stiffness when they are pulled out. So they remain unalterably undressed, although the
