(54) IMPROVEMENTS IN AND RELATING TO FASTENING DEVICES
FOR SUSPENDED CEILINGS
(71) I, ARTUR FISCHER, a German citizen, of Weinhalde 34, D-7244 Waldachtal 3, Tumlingen, Germany, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to a fastening device especially for suspended ceilings, pipes and the like.
To fasten pipes and suspended ceilings, it is known to screw a fastening screw into a tapered bore of, or to withdraw an expander member into the expansible portion of, a fastening element arranged in a hole in an existing ceiling structure so that that element is anchored in that ceiling structure.
The ceilings of buildings are, of course, subjected to vibrations caused, for example, by people walking overhead. In the case of conventional fastening devices this can lead both to the anchorage becoming loose and to perforated securing bands or wires slipping off, if these are joined, for example by way of the fastening screw, to the fastening element. In addition, the anchorage may easily become loose when cracks form in the ceiling.
The present invention provides a fastening device comprising an expansible sleeve for anchoring in a bore in masonry, a bolt mounted within the sleeve, one end of the bolt being provided with an expander member and the other end of the bolt extending beyond the sleeve, a member screw-threaded on the said other end of the bolt for retracting the bolt into the sleeve so that the expander member expands the sleeve, the retracting member being provided with mounting or attachment means, and a resilient means which, in use, is clamped between the retracting member and the face of the masonry in which the bore is formed.
The fastening device is held under tension by the resilient means. The force applied by the resilient means prevents the retracting member from becoming loose when the ceiling structure is subjected to vibration and also prevents the anchorage from becoming loose, by acting, through the retracting member and bolt, on the expander member in a sense to pull it further into the sleeve.
The resilient means is advantageously so designed that the expander member is drawn into the expansible sleeve under considerable pressure, thereby ensuring that the anchorage does not loosen even if cracks form in the ceiling structure.
Wires, or perforated securing bands and the like can be fastened directly to the retracting member by virtue of the mounting or attachment means and consequently any risk of their dislodgement-which can occur with conventional fastening devices as mentioned previously-is removed.
A suitable mounting means is an opening or bore in the retracting member in which are hung wires and hooked shaped projections from which the perforated securing bands can be suspended. The opening may also be used to receive a lever for screwing tight the retracting member. It is also possible to make the retracting member from a square--or hexagonaWsection tube, so that the external face enables a square or hexagonal spanner to be placed around it.
Preferably, the resilient means is a compression spring.
Advantageously, that portion of the retracting member which extends beyond the said other end of the bolt is flattened.
This design facilitates formation of the mounting means which may be in the form of an aperture and/or a projection punched in the flattened portion of the retracting member.
A fastening device constructed in accordance with the invention will now be described, by way of example only, with reference to the accompanying drawing, the single figure of which shows a part sectional side elevation of the fastening device which has been mounted in a bore in masonry.
Referring to the accompanying drawing, the fastening device indicated by 1 comprises a slotted expansible sleeve 2 and a stay bolt 4 provided at one end with an expander member in the form of a cone 3.
At its other end the stay bolt 4 is provided with a screwthread 5.
To anchor the fastening element 1 in a ceiling structure 6, a hole 7 is first drilled in the ceiling into which the sleeve 2 of the fastening device is inserted. The sleeve 2 is then expandedas explained below-by screwing a retracting nut 8 onto the end of the stay bolt 4 projecting from the ceiling. A washer 10 is arranged to engage the face of the ceiling 6 in which the hole 7 has been formed, and between the washer 10 and the retracting nut 8 is arranged a resilient member 9 in the form of a compression spring made of coiled wire. As the retracting nut 8 is turned on the screwthread 5 of the bolt 4, the spring 9 is compressed and the bolt 4 is withdrawn into the sleeve 2. Withdrawal of the bolt 4 into the sleeve 2 results in the cone 3 expanding the slotted portion of the sleeve so that the expanded sleeve firmly holds the device in the hole in the ceiling. The spring serves, when the bolt 4 has been retracted sufficiently to hold the fastening device constantly under tension even if the ceiling is subsequently subjected to vibration.
The retracting member 8 is in the form of a sleeve having an inner screwthread 11 which is matched to the external thread 5 of the bolt 4. A portion 12 of the retracting member which extends beyond the threaded end of the bolt 4 is flattened and is provided with an opening 13. The opening 13 can be punched out in a simple manner since the portion 12 is flattened.
The opening 13 can be used to receive supporting wires or flexible perforated securing bands or tapes (made from, for example, metal or plastics material) or other securing means which may be passed through the opening 13 or hooked through it. The wires or bands may be used, for example, by forming a loop, to suspend bundles of cables (for example, electric cables) or pipes (gas or water, for example).
Further, it is possible to pass a lever, for example the shank of a screwdriver, through the bore 13 of the opening to facilitate screwing of the retracting nut 8 onto the stay bolt 4 in order to expand the sleeve 2.
Alternatively, the nut 8 could have a tubular portion of, for example, square or hexagonal section so that it could be tightened on the bolt 4 by a spanner.
The mounting or attachment means for cables, pipes or suspended ceilings need not be in the form described and illustrated and, for example, the nut 8 could be formed with a hook, lug or bush for fastening purposes.
Securing means in the form of flexible bands and wires have been described above.
However many other types of securing means may be attached to the fastening device. For example rigid strips (which may be metal) could be attached to the ends of a number of the fastening devices to provide a framework for securing a suspended ceiling-the strips having apertures for that purpose.
WHAT I CLAIM IS:
1. A fastening device comprising an expansible sleeve for anchoring in a bore in masonry, a bolt mounted within the sleeve, one end of the bolt being provided with an expander member and the other end of the bolt extending beyond the sleeve, a member screw-threaded on the said other end of the bolt for retracting the bolt into the sleeve so that the expander member expands the sleeve, the retracting member being provided with mounting or attachment means, and a resilient means which, in use, is clamped between the retracting member and the face of the masonry in which the bore is formed.
2. A fastening device as claimed in claim 1, in which the resilient means is a compression spring.
3. A fastening device as claimed in claim 1 or claim 2, in which that portion of the retracting member which extends beyond the said other end of the bolt is flattened.
4. A fastening device as claimed in claim 3, in which the mounting means is in the form of an aperture provided in the flattened portion of the retracting member.
5. A fastening device substantially as hereinbefore described, with reference to and as illustrated by the accompanying drawing.
