Description

DEVICE FOR FASTENING EQUIPMENT ON A

The invention relates to a device for attaching equipment, in particular a water heater or a boiler, to a vertical wall, in particular a wall of a room.

A water heater may be installed in a room by resting on the floor by means of feet or a pedestal or be fixed on a vertical wall by means of fixing points such as tabs, stirrups or flanges.

In the latter case, the traditional water heaters or thermodynamic wall have a tank containing the water to be heated and have the distinction of being able to be fixed on the wall of a room. The installation of such a water heater requires a preparation prior to installation which consists in fixing a number of anchoring means such as pegs, lag bolts, lugs or other support pieces, and sufficiently sized to accept the load. water heater and its contents. Most of the time, the installer must then raise the water heater manually or using a lifting device to match the water heater attachment points to those on the wall.

This maneuver is often made very difficult by lifting efforts that can be around 75kg with more difficulty in gripping the water heater by its circular section.

Moreover, the thermodynamic water heaters often have the particularity of having a heat pump at the top, which has the effect of moving the center of gravity of the product upwards compared to a traditional water heater and therefore to promote the tilting of the product. This implies an extra vertical holding effort asked the installer during handling.

If we add to this problem the case of adverse environment where the water heater must be installed in a confined space and inaccessible to the installer, closet type, it becomes impossible to access the points of attachment which is partly back of the product for screw fastening or to check that the water heater is securely fastened to the wall. The invention solves these problems by means of a device for fixing equipment on a vertical wall which ensures a great ease of handling, a reduction of the effort to be provided for the installer and an automatic locking of the fixing points without intervention at the rear of the equipment.

To do this, the invention proposes a device for fixing equipment on a vertical wall, characterized in that it comprises - at least one vertical upright intended to be fixed on said vertical wall, - at least one arm of which one end is pivotable on said upright near the lower end thereof and the other end is pivotable on a support piece intended to be fixed to said equipment and - a self-locking means carried by said upright in the vicinity its upper end and intended to self-lock with said support part, when said equipment is moved against the vertical wall.

The number of uprights and arms is one or two depending on the section of equipment, rectangular or circular.

With the device according to the invention, when mounting the equipment on the vertical wall, the equipment is guided in its path to the self-locking points and the installer just has to worry about lifting without having to aim at these locking points. The kinematics of the device allows the user to exert a vertical lifting force without having to maintain the product in its upper part to prevent tipping of the product. The effort to be provided is reduced by the recovery of the loads on the pivoting arms especially in the upper part where the equipment is almost at arm's length.

It also results in a gain in installation time, the need for a single installer instead of two and increased installation security. Self-locking makes it possible to avoid tedious manual intervention in the rear area, especially in a confined closet-type environment. This locking is definitive and can not be disassembled over time because of the vibrations of the product.

According to a preferred embodiment, the pivoting joint between said arm and said post is slidable in the vertical direction.

Advantageously, the pivoting joint between said arm and said upright is disposed in an oblong vertical sliding hole arranged on said upright.

Preferably, said self-locking is performed by gravity.

Said self-locking means is advantageously a vertical slot for embedding said support piece arranged on said upright.

Preferably, the device comprises a second support piece intended to be fixed to said equipment under said first support piece and second self-locking means carried by said upright near its lower end and intended to receive with a second self-locking device. locking said second support piece.

Said second self-locking is advantageously performed by gravity.

Said second self-locking means is advantageously a vertical slot for embedding said second support piece arranged on said upright.

A gas spring may be arranged near the pivoting joint between said arm and said post.

Anti-vibration devices can be inserted at each pivoting joint.

Preferably, the device comprises two said parallel amounts and a said arm associated with each amount. The invention also relates to equipment intended to be fixed on a vertical wall and provided with such a device.

Preferably, this equipment is a water heater or a boiler.

The device according to the invention can indeed be integrated with each water heater or boiler or be sold as an accessory. The invention is described below in more detail with the aid of figures representing a preferred embodiment of the invention.

This support piece 7 is a stirrup formed of a flat profile 7A intended to be fixed by screwing on the outer enclosure of the equipment 1, whose two ends are bent perpendicularly. The pivoting joint between each arm 5, 6 and the corresponding amount 3, 4 is sliding in the vertical direction, as best seen in Figure 3 which shows a single upright 3 knowing that the two parallel uprights 3, 4 are symmetrical . To do this, this pivoting joint between each arm 5, 6 and the corresponding amount 3, 4 is disposed in a vertical oblong hole 3C, 4C of sliding of the pivot axis, this oblong hole 3C, 4C being arranged on the upright corresponding.

As for the self-locking which is preferably achieved by gravity, it is particularly illustrated in Figures 4A to 4C.

In these figures is shown a single amount 3 knowing that the two parallel uprights 3, 4 are symmetrical.

Each upright consists of an L-shaped section whose base 3 'is intended to be fixed on the vertical wall 2 and whose perpendicular branch 3 "carries this self-locking means here formed of a vertical slot 3" A mounting of the support part 7 fixed to the equipment 1.

Upstream of this slot 3 "A on the path of the support part 7, when the equipment 1 is moved towards the vertical wall 1, the branch 3" of each upright has an inclined bearing cutout 3 "B, on which press the support piece 7, as illustrated in Figure 4A, and on which is guided this support piece 7 until it is embedded in the slot 3 "A as shown in Figures 4B and 4C.

More specifically, this support piece 7 is a stirrup formed of a flat profile 7A intended to be fixed by screwing on the outer enclosure of the equipment 1, whose two ends are bent perpendicularly to form a flange 7B parallel to the wall corresponding arm 5. The pivoting joint between arm 5 and support part 7 consists of a screw and nut arrangement arranged on these flanges.

As can be seen in FIG. 1, the device may comprise a second support part 8 intended to be fixed to the equipment 1 under the first support part 7 and a second self-locking means carried by each post 3, 4 close to its lower end 3A, 4A and adapted to receive with second self-locking this second support piece 8.
