Definitions
- the present invention relates to a dampened floor support device adapted to be attached to a floor joist in a floor system.
- Another development is providing dampening in the foot in contact with the underlying surface, such as the floor support structure disclosed in SE 540 180 . Therein, the foot is separated into two parts and a dampening material is provided between said parts.
- a drawback with the solution provided in SE 540 180 is that the dampening material needs to be attached to the lower and upper part in order to keep them together. Using an adhesive is possible, but does not provide satisfactory strength and reliability. Another approach is to use a rubber dampening material which is vulcanized to the upper and lower parts. This does provide satisfactory structural strength, but is expensive and time-consuming. Also, the rubber material is susceptible to wear and tiring, and therefore not ideal for dampening.
- An object of the present invention is thus to alleviate at least some of the aforementioned problems with the prior art.
- snap-fitted is to be understood as bringing two elements into direct physical contact with each other whereupon they are arranged in a latched position so that the movement of one element at least partially induces movement in the other element, or that movement of one element in at least one direction is restricted by the other element.
- a floor support device comprising a foot and a level adjustment screw, the level adjustment screw being adapted to be attached to a floor joist; wherein the foot comprises an upper part arranged to receive the level adjustment screw, the upper part comprising a lower surface, a lower part intended to contact an underlying surface, the lower part comprising an upper surface, and a dampening material sandwiched between the lower surface and the upper surface; characterized in that: the lower part engages with one of the upper part and the screw so as to prevent detachment of the lower part from the upper part, while allowing compression of the floor support device.
- the foot By having the lower part of the foot engage with the upper part of the foot while having the dampening material sandwiched in between, the foot is held together without the dampening material having to be processed, such as by adhesive or vulcanization. This allows for a faster, easier and cheaper assembly of the floor support device.
- the dampening material may also be freely chosen, without considering such processing.
- the engagement allows for compression of the floor support device, which entails that a decrease of distance between the lower surface and the upper surface is allowed, i.e. the parts may be moved towards each other.
- the engagement also allows for expansion, i.e. moving the parts away from each other and so that the dampening material may expand.
- the engagement prevents detachment, i.e. ensures a mechanical connection between the parts.
- the engagement therefore defines an end position at which the distance between the lower surface and the upper surface is at a maximum, and hinders an increase in distance beyond that maximum value.
- the lower part engages with both the upper part and the level adjustment screw.
- the lower part of the foot comprises at least two prongs extending in a substantially axial direction of the floor support device, the at least two prongs being adapted to engage with the upper part such that the upper part is snap-fitted to the at least two prongs.
- the at least two prongs may include two prongs arranged on opposite sides of the lower part of the foot.
- the at least two prongs may be arranged in such a way so that they, when engaging with the upper part, are arranged on the outside of the dampening material, i.e. that the at least two prongs at least partially envelopes, or at least partially encases, the dampening material such that it is hindered to move in at least two directions in a plane horizontal to the floor support device.
- the dampening material is held together with the rest of the floor support device without it having to be processed, such as by vulcanization.
- the dampening material may be press-fitted between the at least two prongs such that it is latched between them.
- the floor support device comprises four prongs spaced along a circumference of the lower part.
- the four prongs may be arranged in such a way so that they, when engaging with the upper part, are arranged on the outside of the dampening material, i.e. that the at least two prongs at least partially envelopes, or at least partially encases, the dampening material such that it is hindered to move in at least one direction in a plane horizontal to the floor support device.
- the four prongs may be equally spaced along a circumference of the lower part.
- the lower part of the foot comprises a hook arranged substantially centered in the lower part and extending through the dampening material in a substantially axial direction of the floor support device, the hook being adapted to engage with the level adjustment screw such that the hook is snap-fitted to the level adjustment screw.
- the floor support device By having the hook extend from the lower part to the upper part, through the dampening material, and snap-fitted to the level adjustment screw, the floor support device is kept together without having the dampening material processed. Furthermore, due to the hook being extended through the dampening material, movement of the dampening material in a plane horizontal to the floor support device is restricted.
- the upper part comprises an opening adapted to receive the level adjustment screw.
- the opening receives the level adjustment screw so that it is arranged within restricts movement of the screw in a plane horizontal to the floor support device.
- the screw may be arranged in the opening without any direct physical contact with the upper part.
- the screw is adapted to be arranged within the opening such that it is free to rotate about a longitudinal axis of the screw.
- the dampening material comprises a through hole adapted to receive the hook such that the hook extends through the dampening material and engages with the level adjustment screw.
- the hook By having a through hole adapted to receive the hook, the hook is easily extended through the dampening material so that it may reach the upper part so that the lower part engages with the upper part.
- the through hole may be larger than the hook so that the hook, when extending through the dampening material, is not arranged in direct physical contact with the dampening material.
- the through hole may also be small enough so that the dampening material is pressed outwards from the hook when the hook is fitted within, thereby allowing the dampening material to be attached to the hook.
- the lower part further comprises at least one off-center hook adapted to engage with the upper part, and wherein the dampening material comprises at least one off-center through hole adapted to receive the off-center hook.
- An off-center hook is to be understood as a hook that is arranged in a position offset from a center of the lower part of the foot.
- An off-center through hole is to be understood as a through hole that is arranged in a position offset from a center of the lower part of the foot.
- the lower part engages with the upper part in at least two positions, whereby the support foot is not only held together better, but the upper part and/or the dampening material is hindered from rotating around a center of the lower part.
- the level adjustment screw comprises an opening on a distal end adapted to receive the hook such that the hook is snap-fitted to the opening.
- the hook and the screw are arranged in mechanical contact with each other.
- the hook is adapted to be snap-fitted to the level adjustment screw such that the screw is free to rotate about a longitudinal axis of the screw.
- the dampening material is substantially rectangular.
- the dampening material does not have to be cut or otherwise processed in order to acquire a certain geometric shape, such as a circular shape, thereby reducing material waste, thus making the floor support device cheaper to manufacture
