It is also an object of the present invention to provide a gasket for flush mounting of units and devices used in unit and combination installations to achieve the requirements of the IP44 protection class. Further, the invention relates to a sealing system for sealing co-10 devices and devices used in composite installations for flush mounting to meet the requirements of the IP44 protection class. In the context of the present invention, devices and devices include e.g. sockets, switches, various telecommunication and data sockets, mounting accessories, etc.

_. _ 15 Instruments and appliances used in humid environments have an enclosure protection class of IP44. Nowadays . ·. : this combination of wet compaction sealing for combination installation has been implemented:. using a two-stage sealing arrangement, in which case there are two separate sealing arrangements. One of these seals is the so-called. a box seal and a second so-called. Wall seal. The function of the box seal is to prevent splash water itself:: ': 20 from the sides of the instrument and the function of the wall seal is to seal the gap between the cover plate and the wall. When multiple devices or devices are installed side by side, the top surface of the box seal in current solutions is then planar. This ra- V; the planar upper surface of the gasket is fitted between the instrument box or device box itself and the mounting brackets attached to it. When installing • • ♦ 25 multiple devices side by side, each unit has its own wall-mounted · 1 · ,. vistekokoa. Thus, there are wall seals for one, two, three, etc. compartment cover frames. With known solutions, IP44 enclosure classes currently require the use of two separate sealing arrangements and, for each number of devices, 1.2, 3, etc., with their own wall seals.

Fig. 1a shows a state-of-the-art sealing arrangement for single instrument or device 1P44 · * ·., in flush mounting, according to the prior art. Inside the housing box 1, a box seal 10 can be fitted, the upper part 11 of which is planar. The bottom portion 12 of the box seal • · · 10 has a water drip rim 13, whereby any drop of water drops so that it does not hang on the bottom edge 15 of the bottom seal 12. This solution effectively prevents any water drop contact with the instrument inside the box seal. On the upper part 11 of the box gasket 10 a mounting ring 23 and 107087 3 can be mounted on the brackets 30, on which a cover plate 40 can be mounted. In the middle of the cover opening a center plate of the device or device with e.g.

Figure Ib shows another prior art single box seal arrangement for flush mounting in a reduced view. In this solution, only one gasket is used to achieve the IP44 degree of protection. In this solution, the edges of the upper portion 111 of the box seal 100 are raised to form the raised edges 121, whereby one seal replaces the two seal system shown in Fig. 1a. Such a solver has been used only to seal individual instrument or device boxes to IP44 protection class requirements.

Figure 2, in turn, illustrates a prior art solution for an IP44 enclosure arrangement used in combination installations in connection with flush mounting. In this figure, a sealing arrangement according to two instrument boxes is used.

Figure 3 illustrates the formation of a sealing arrangement for two IP44 enclosure enclosures. In the solution according to our invention, a raised edge 221 is provided in connection with the upper part 211 of the box seal 200 which, as its name indicates, is raised 107087 4 in a manner similar to the known one-seal solution according to Fig. Ib. The solution of Figure Ib developed by the patentee can only be used when installing individual instrument or device boxes, since the box seal in question is a single integral unit.

However, at least one of the raised edges 221 of the box seal 200 according to our invention is removable, preferably without tools, e.g. by tearing along the perforation 222, whereby the two adjacent edges 224 of the box seal 211 and the raised edges 221 extending into each other so tightly that when a cover plate 42 is mounted on this sealing system, a sealing arrangement meeting the IP44 protection class requirements is achieved. Instead of perforating 222, another way can be used to easily remove the pieces 223 from the raised edge 221 in the case of a composite installation. Thus, using the solution-15 according to our invention can be replaced in a combination installation by a box seal system and: '·,: wall seals with only one seal assembly. This means that no separate wall seals are needed at all.

: The top portion 211 of the box seal 200 includes raised edges 221 and at least one perforation 222 '20 or equivalent attenuation attaching at least one raised edge 221 to the top portion 211 of the box seal 200 and that at least one of the worn edges 221 by means of a perforation 222 fitted to the raised edge 221 or equivalent attenuation, preferably without tools, e.g. by tearing, so that the successive raised edges 221 of the adjacent box seals 200 are aligned with each other. 25, and the edges 224 of the upper portions 211 are closely adjacent to each other to provide a sealing system meeting the requirements of IP44 protection class together with the cover plate 42.

Fig. 4 shows a solution according to our invention in a combination installation a-30 mounted on two adjacent instrument boxes 1. In this case, a box seal 200 is fitted in connection with the instrument box I, from which one piece 223 of the raised edge 221 is removed from each side seal 103 of the rib seal 223, which in this combination installation is disposed adjacent to the second box seal 200. Here, the adjacent upper edges 224 of adjacent box seals are adjacent to one another and the raised edges 211 extend apart and provide a seal assembly of IP44 protection class with only one type of seal, that is, the box seals of the invention.

The upper part of the raised edge 221 of the box sealing upper portion 211 is spaced a distance above the upper surface of the fastening ring, and preferably substantially above the upper surface of the fastening bars. This stiffening of the box seal 200 can replace a separate wall seal.

The perforations 222 or similar attenuations in the box seal 200 are preferably disposed on opposite sides of the top portion 211 of the box seal at the inner edge of the raised edges 221 so that when installing 3 or more box seals 200 in succession. : from each of the box seals between the outermost box seals 200 removes: portions 223 of raised edges 221 on opposite sides, whereby the box seals; · \ Are placed close to each other and IP44 protection is achieved in: 'i'.
