Description
July 4, 1950 K. G. EKLUND ETAL AIR INTRODUCING DEVICE Filed 001;. 7, 1948 Patented July 4, 1950 UNITED s rlrrizs The present invention relates to devices for introducing air into rooms for ventilation purpose. The device is of the type in which a noz zle member having a substantiallyspherical bearing surface is supported in a frame structure the nozzle member being adjustable to different positions due to its spherical bearing surface so that the air jet discharged from the device can be set in various directions.
.The main object of the invention is to. provide a device of said type, in which the adjustment of the nozzle member to the different discharge positions may be easily effected.
Another object of the invention is to provide spring means for keeping the nozzle member in position in the frame, said spring means being mounted so as to facilitate dismounting and mounting of the device.
With the foregoing and other objects in view, as will appear as the description proceeds, the invention resides in the combination and arrangement of parts and details of construction described herein and particularly pointed out in the appended claims, it being understood that changes in the particular embodiment of the invention may be made within the scope of the claims without departing from the spirit of the invention.
In the drawing Fig. 1 is an axial section of an air introducing device according to the invention, a valve means associated therewith being in a fully open position, and
Fig. 2 is a rear view of the same device but having the valve means in a fully closed position.
In the drawing, I denotes a wall in which a ventilation conduit or passage conveying the air to the device has its mouth. Mounted in said mouth is a frame 2, an annular flange 3 being secured releasably thereto by suitable threaded fastenings such as set screws at spaced points as indicated at 3' in Fig. 2. This flange carries the nozzle member through which the air is discharged. Said nozzle member has a spherical bearing surface 4 at its outer periphery. The nozzle member 5 is shown as a spherical ring having an inlet opening 6 and an outlet opening 1 for the air, said openings being located in two parallel planes extending at right angles to an axis in the sphere. It is assumed that air is admitted to the device in the direction indicated by the arrow 8. The nozzle member or ring 5 has its spherical surface 4 fitted into the opening of the flange 3, the inner edge of the latter thus forming a, seat 9 which is engaged by the bearing surface 4. Toobtainthe necessary thrust for pressing.the;-bearing surface 4 against the seat 9 a helical spring -I U is mounted betweena supporting surface. Hat the centre-of the spherical surface 4. andag-fixed support means in the form of a. 'bowlZ suitably madefrom steel band-and having its. endssecured'to the flange-:3 between the latter. and :the framed, ,for example by riveting. The devicecomprises,v guide vanes- 14 in the passage ;of the nozzle member, said guide vanes being of any suitable shape such as straight and oblique or helically curved with respect to the axis of the device. The supporting surface H is located at one end of an axial extension N5 of a hub [6 which is common to all guide vanes. A spring retainer in the form of a pin I! may be provided for one end of the spring In at the supporting surface l I, and a similar retaining pin 18 may be provided at the bow l2 for the other end of the spring. The pin I8 is riveted to the bow i2 at a point coaxial with the axis of the spherical bearing surface 4, when said axis is situated in its central position as illustrated in Fig. l.
The passage of the nozzle member may be closed more or less by means of a pair of substantially semi-circular valve members 19, 20 which in their closed position each cover its half of the passage. The valve members are formed with opposed peripheral lugs I9 and 26 respectively, by means of which they are journalled on pivot pins 21 mounted in diametrically opposite relation to one another in the ring 5. The pivot mounts for the valve members I!) and 20 provide sufiicient frictional resistance to retain the same in Whatever position they may be set. They may be manually set in the desired position in any suitable manner, as for instance by use of a hooked rod (not shown) inserted between the vanes M, the manner of manipulation being no part of the present invention.
As the device is set to various discharge directions, the axis 22 of the spherical surface 4 changes its position. One oblique position of the said axis is indicated by the chain-dotted line 22 in Fig. 1. During such adjustment the supporting surface H still remains at the centre of the spherical surface about which the axis rotates. The spring force imparted by the spring ill will be substantially unchanged during the adjustment, since the distance between the supporting surfaces for the ends of the spring remains constant. By this the adjustment will be facilitated.
The guide vanes 14 and the hub [6 to which they are secured form a single air guiding structure or unit which is releasably fitted to the inner side of the spherical ring 5. The outer edges of the guide vanes are shaped to seat firmly on the inner surface of the ring 5 so that the frictional engagement between the guide vane unit and the ring 5 under pressure of the spring II] will prevent relative movement between them even when the struetureiisetilted to or somewhat be yond the angle of the line 22, which is about the maximum that would be desired in actual op eration. Thus the spring l0 serves the dual purpose of retaining the guide vane unit irrosi tion in firm engagement with?tire-inner surface.n
of the ring 5 and through pressure transmittedii through the guide vane unit toeretainitheringg 5 in engagement with the seat9ori' theflangeg.
