BODY FRAME

The invention relates to a basket frame as defined in the preamble of claim 1.

Generally, the elevator car is attached to its supporting structure, a sling or basket frame, to support the car in the shaft. The basket frame may be formed such that the lifting point is either behind or on the side of the basket. It is known that beams are used as load-bearing structures under the floor, which require a larger lower space for the elevator.

Prior art is disclosed in EP A 700860, which discloses a basket frame comprising a horizontal support element, vertical support elements attached thereto, and upper horizontal beams attached to vertical support elements. The actual elevator car is supported on the above-mentioned horizontal support element. The above horizontal support element consists of a honeycomb and a honeycomb structure.

Generally speaking, the bottom floor of elevator structures should be sought to make. , to minimize costs. Example- * ·. * ·; 20 therefore, when installing elevators in buildings where there were no elevators and were not originally * S :.

According to a preferred embodiment of the invention, the basket frame comprises at least one vertical support element outside the interior wall of the basket and at least one horizontal support element below the floor level of the basket connected to each other and the horizontal support element being a lattice structure. According to a preferred embodiment of the invention, the lattice structure consists of side beams and carrier beams which are transverse to each other and the surrounding edge thereof. According to a preferred embodiment of the invention, the tie beams and the carrier beams 10 are perpendicular to each other. The beams and the beams and the edge are made of durable material, for example steel. According to the invention, it is possible to construct the lattice structure so that the lashing beams and the supporting beams forming the lattice structure are of the same, i.e. equally supportive, structure. According to a preferred embodiment of the invention, the tie beams are thinner than the carrier beams. According to one embodiment of the invention, the lacing beams of the lattice structure are embedded in the carrier beams. The side beams of the structure according to the invention can be placed in the supporting beams so that the required strength 20 is achieved and the beams are parallel to the threshold. The distances between the tie beams and the bearing beams and:. their number in the lattice structure can be varied so that they provide the necessary strength for the structure.

\ J |; According to an advantageous embodiment of the invention, the vertical support element and the horizontal support element of the body frame are connected to each other by an oblique support element. According to another preferred embodiment of the invention, the vertical support element and the horizontal support element of the basket frame are combined. interconnected by a vertical bracket on the side of the basket and a horizontal bracket on the basket.

. · ', According to another preferred embodiment of the invention, the basket * * ·: the vertical support element of the frame and the horizontal support element beneath the basket are secured to each other by inserting the biased supports. According to a preferred embodiment of the invention, a spacer can be placed directly over the floor lattice structure, for example in the form of plywood or sheet metal, on which a floor covering can be applied. The baffle plate and grid structure are easily attached to one another by means of fastening means such as screws, whereby the screws pass through the grid structure. Preferably, the lattice structure extends over the entire floor area. According to the invention, it is possible to use flat bars under the grid structure to reinforce the strength of the floor 5 if the grid structure is thin. The flat bars are secured underneath the lattice structure at the required intervals in the direction of the tie beams. The floor structure according to the invention can be used in an elevator where the distance between the bottom of the shaft and the floor of the elevator car is small, with the car being on the 10 lowest floors.

The thin lattice structure according to the invention is preferably used as a load-bearing structure on the floor of the elevator car. By using a thin floor structure according to the invention, it allows a small lower floor space in the building for an elevator. This saves 15 on construction costs.

The invention will now be described in detail with reference to the accompanying drawings.
