Definitions

  • the invention relates to a ventilating apparatus including a house consisting of two profiles, a rotatable closing device with cylinder wall portions mounted between the profiles, the closing device consisting of one or more closing members mounted to end parts at their outer ends and sealing means between the profiles and the closing members, whereby the closing device can be rotated from a first position with a closed air passage into a second position with a fully opened air passage.
  • This known apparatus has the disadvantage that cleaning the apparatus, more in particular the closing device and possibly mounted wire screens on the outside, is very difficult and in fact can only be done proper by taking the apparatus apart. This is also the case if new wire screens or new closing means have to be mounted on the profiles.
  • Another disadvantage of the known apparatus is that if only a relatively small air flow is wanted to pass the apparatus, for instance with strong winds, the direction of air flow is very difficult to control, which in practice means that for instance in a sleeping room a person almost immediately experiences a sense of draught.
  • the invention provides a ventilating apparatus as defined in claim 1.
  • the air passes along both sides of the closing members, whereby the guide passage for the air between the closing members is smaller than the air passage of the known closing device, the total area of the different air passages together, however, being at least equal to that of the known closing device.
  • the air flow can be directed very accurately.
  • a ventilating apparatus is known with a closing device consisting of two closing members with a central air passage between the closing members.
  • the outer boundaries of the closing members are lying on the same imaginary cylinder, which makes it impossible to remove the closing device from the ventilating apparatus, without demounting the ventilating apparatus.
  • the ventilating apparatus known from the Dutch patent application NL-A-7505355 has a closing device with only one closing member, which makes it impossible to direct the air flow accurately by a small air passage.
  • the ventilating apparatus described in the British Patent GB-A-1,006,828 also does not allow to take the closing device out of the ventilating apparatus without demounting the apparatus and to direct the air flow.
  • a preferred embodiment of the invention provides in that the closing device consists of at least two closing members spaced from each other, whereby each closing member has the shape of a cylinder slice with two parallel planes and two cylinder wall portions of the same cylinder.
  • the ventilating apparatus When the ventilating apparatus is set in a position with only a small air passage, thus only using the central guide passage, the air flow can be directed very accurately over an angle which is dependent on the radial measurements of the closing members and the guide passage.
  • the air flow will be directed inclined to the horizontal and preferably in a upward direction, so that considerable less draught is experienced than with an undirected air flow.
  • a rigid and simple construction for the closing device is obtained by providing that the end parts fit into the closing members. To prevent a possible heat transmission between the outer ends of the closing members it is provided that the end parts are made of plastic material.
  • Another embodiment of the invention preferably provides that the closing device is removable and that a wire screen mounted at the outside thereof is removable to the inside.
  • the wire screen can be mounted in grooves in a vertical or inclined position, the upper groove having a greater depth than the lower groove.
  • both the grooves can be made with the same depth, whereafter filling pieces are inserted into the lower groove.
  • the invention not only comprises a ventilating apparatus as depicted above, but also the profile needed for the manufacturing of the closing members of the closing device. Accordingly the invention provides a hollow profile having an outer shape with two parallel flat planes, connected to each other by cylinder wall portions, which form part of the same imaginary cylinder. Also the end parts, forming together with such hollow profiles the closing device, are part of the invention.
  • the ventilating apparatus according to fig. 1 consists of a bottom profile 1 and a top profile 2 with a rotatable closing device 3 mounted between these profiles.
  • the closing device is mounted in bearings 26,27 (vide fig. 2, 3 and 4), which are part of the closing parts connecting the outer ends of the profiles 1,2. These closing parts are not shown in the drawing.
  • the bottom and top profiles 1,2 both consist of two parts 4,5 and 6,7, which are connected to each other according to a known method with a connecting piece 8,9 of plastic material to prevent the forming of a "cold-connection".
  • profiles are provided with connecting means 11,12 for a not shown insect screen or wire screen, which are mounted in such a way, that the insect screen has a vertical position, but which just as good can be mounted in such a way that the screen has an inclined or horizontal position.
  • a cap 10 is mounted to prevent the rain from coming in.
  • the closing device 3 has two hollow closing members 13, 14, with in between a guide passage for the air 23.
  • the boundary planes 15,16,17,18 of the closing members 13,14 are lying on an imaginary cylinder and are, with the two closing members 13,14 in a vertical position, in contact with the brushes 19,20,21,22 mounted in pairs on the bottom and top profile 1,2.
  • Fig. 2 schematically shows a front view of the closing device 3, rotatable in bearings 26,27, which are mounted in or form part of the closing parts connecting the lower and top profiles 1,2.
  • the closing members 13,14 are connected with end parts 24,25 fitting into bearings 26,27. These end parts 24,25 are made of plastic material to avoid a "cold-connection" also at this spot.
  • cut-outs 28,29 with the form of a circle segment are made, so that the end parts 24,25 are free over less than 180 degrees, whereby in the free part of end part 25 holes 30,30′ are made for a control handle 31 for the closing device 3.
  • the angle enclosed by the cut-outs is such that the closing device 3 with the control handle 31 can be rotated from a fully closed position to a completely opened position.
  • Fig. 2, 3 and 4 show the construction that permits the removal of the closing device 3 out of the ventilating apparatus in an easy manner, as a result of which the screen placed on the outside can be reach from the inside.
  • the end part 25 With the axial force exerted by the spring 32, mounted between end part 24 and bearing 26, the end part 25 is hold in the bearing 27, where it butts against a removable ring 34.
  • sufficient space is left between the end part 24 and the bearing 26, so that by moving the closing device 3 against the force of the spring 32 the end part 25 can be moved out of the bearing 27, whereafter the closing device 3 can be removed from the ventilating apparatus to the outside.
  • the end part 24 has a somewhat tapered form. Although theoretically a spherical shape is needed, in practice a truncated cone shape will do in most cases.
  • the bearing both have the same outer dimensions because of the equal measurements of the closing parts. This means that the bearing 27 has larger dimensions than is strictly necessary to support end part 25.
  • the bearings 26,27 have exactly the same bores, whereby the space in bearing 27 is filled partly with a ring 34 and the spring 32 is kept in bearing 26 by mounting it to a removable plate 33.
  • a ring 34 with the plate 33 and spring 32, to remove and control the closing device from both the left side and the right side, whereby the control handle has to be removed from hole 30 to hole 30′ or vice versa.
