National foreword

This Part of BS EN 1129 has been prepared by Technical Committee CCM/37 and

is the English language version of EN 1129-1:1995 Furniture — Foldaway

beds — Safety requirements and testing — Part 1: Safety requirements published

by the European Committee for Standardization (CEN)

EN 1129-1 was produced as a result of international discussions in which the United Kingdom took an active part

A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application

Compliance with a British Standard does not of itself confer immunity from legal obligations.

1 Scope

This Part of EN 1129 specifies requirements

relating to the safety and the strength of foldaway

beds for domestic use

The standard also covers the strength of wall

fastenings where applicable

This standard does not specify the properties of the

materials or electrical equipment used in the

construction of foldaway beds

Folding beds, camping beds and convertible

bed/chairs or settees are not covered by this

standard

In Annex A (informative), the requirements are

shown schematically in relation to the testing

procedures

2 Normative references

This European Standard incorporates, by dated or

undated reference, provisions from other

publications These normative references are cited

at the appropriate places in the text and the

publications are listed hereafter For dated

references, subsequent amendments to or revisions

of any of these publications apply to this European

Standard only when incorporated in it by

amendment or revision For undated references the

latest edition of the publication referred to applies

methods

3 Definitions

For the purposes of this standard, the following

definition applies:

3.1

foldaway bed

a foldaway bed (hereafter referred to as bed) is a bed

whose sleeping surface is rotated about at least one

horizontal axis when being positioned for use

4 Safety and strength

4.1 Construction

Exposed edges and protruding parts shall be

rounded and free from burrs or sharp edges There

shall be no open-ended tubes

4.2 Folding fittings

There shall be no shear and pinching points unless

they are secured against unintended access

When tested in accordance with 5.4 of

EN 1129-2 the folding fittings shall be such as to ensure that neither the opening nor the closing force shall vary by more than 20 % between the two measurements

4.3 Mounting of the foldable part to the frame

The folding mechanism shall be fastened to the structure by means which will remain tight throughout the service life of the bed

The fasteners shall not loosen after testing in

accordance with 5.4 of EN 1129-2.

NOTE Experience has shown that a nut and bolt are satisfactory but an ordinary wood screw may not be.

4.4 Strength and durability

When tested in accordance with 5.6 of EN 1129-2,

neither the constructional elements nor the wall mounting structure shall have loosened nor shall there be any damage which will affect the function and safety of the bed

4.5 Unintended closing

When tested in accordance with 5.5.3 of EN 1129-2,

the foldable part shall not close automatically, i.e the supports shall not lift more than 5 mm from the floor

4.6 Unintended opening

The foldable part shall reclose automatically when opened up to a distance of 150 mm, measured from the top edge (see Figure 6 of EN 1129-2)

The pressure force applied to the defined loading point (see Figure 6 of EN 1129-2) shall be greater

than 250 N when tested in accordance with 5.5.4 of

EN 1129-2

Either the opening force required shall be not less than 20 N or a positive retaining catch shall be provided which retains the bed firmly in the closed position and which can be released only by use of a manual security device, e.g a key or a double action button

Locking mechanisms shall be constructed so that the operating force is at least 50 N In the case of revolving elements, this force shall be applied tangentially at the point on the element furthest away from the axis of rotation

The opening energy, measured at an opening angle

of 70°, shall not exceed 10 Nm1) when measured in

accordance with 5.4 of EN 1129-2.

1) This value is measured taking into account the mass of the bed and the opening speed or the energy resulting from this

opening speed.

4 © BSI 09-1999

However, bed constructions with an opening energy

of up to 60 Nm1) and gravity controlled beds with an

opening energy of up to 120 Nm1) (measured at an

opening angle of 70° in each case) are acceptable,

providing the following conditions are satisfied

a) Opening

— Automatic closing after an opening length

of 250 mm; and

— weight to be supported during the opening

process not greater than 100 N

b) Closing

— Opening length up to the automatic closing

point for end pivoting beds 350 mm and for side

pivoting beds 300 mm

NOTE Opening energy more than 60 Nm, respectively more

than 120 Nm, is not accepted.

5 Mounting of the bed to the building

The bed shall be so constructed that its mounting

shall conform to the following requirements

NOTE Floor-to-ceiling beds, the mounting of which cannot be

pulled over because of its proximity to the ceiling, are excluded.

There shall be, at least, two fixing points and there

shall be, at least, two holes for attachment in each

fixing point (see also clause 6) The fastening

devices and the installation instructions shall be

supplied with the bed

The design of the fastening devices shall be such

that no additional forces due to sagging of the floor,

e.g carpet or soft floor, up to 15 mm, may be

transmitted to fastening devices They shall be

connected to the frame by the means described

in 4.3 or any equivalent safety devices The

fastening shall not be capable of being released from

the inside

6 Installation instructions

Each bed shall be supplied with two sets of installation instructions One durably and visibly attached near the fastening point The instructions shall contain at least the following information: a) a warning against incorrect installation; b) the necessity for installation, and any further adjustment, to be carried out by competent persons only;

c) the need to check the suitability of the floor and wall and that the fastening devices supplied with the product will withstand the forces generated;

d) value of the test force FH on each attaching point;

e) the number of screws required, calculated in accordance with Annex B, for each fixing point; f) the minimum and maximum weight of the mattress unless the bed is supplied with a mattress and/or has an adjustable tension system

7 Marking

All beds for which claim for conformity to this standard is made shall be marked with the following information:

a) the name, registered trade name or registered trade mark of either the manufacturer,

distributor or retailer;

b) the number of this part of EN 1129

EN 1129-1:1995

Annex A (informative)

Foldaway beds: Test scheme

Annex B (normative)

Calculation of the minimum number of screws for fixing points

The location of the screws and the material thickness of the fitting shall be such as to ensure that the tensile force is equally distributed to all wall screws

The distance between the single wall screws shall be at least 50 mm

The minimum number n of screws to be used for each fixing point on the wall is calculated by the following

equation:

where

FH = Fp × 5 + 100

where

NOTE This depends on the strength of the respective wall which has to be determined individually.

The maximum force on each fastening point during opening and closing procedure may be determined by calculation or measurement Tensile loads shall be considered positive but compressive loads shall be given zero value

Fp is the maximum horizontal force on each fastening during opening and closing procedure;

FH is the retaining strength of each fixing point (U 400 N);

FS is the retaining force of each wall screw (resistance to drawing out)
