Description
@cit 9, 1934. E. F. BELL wINDow AwNING CONSTRUCTION Original Filed Dec. 24, 1931 Patented Oct. 9, 1934 UNTED STATES WINDOW' AWNING CONSTRUCTION Appiication December 24, 1931, Serial No. 582,903 Renewed March 14, 1934 13 Claims.
This invention relates to Window awning constructions and has for one of its objects to producebrace means for pivoted awning arms, which will prevent vibration of the awning through the action of the wind lifting the front pole, and
which will automatically collapse when the awning bracket has been moved to a predetermined point to permit the arms to pivot or fold when it is desired to collapse the awning.
A further object of the invention is to produce a construction of the character set forth which may be used with automatic window awnings of the visor type, in which means is provided to prevent downward falling of the awning structure upon the folding movement of the visor portion thereof, and in which the visor may be adjustably positioned at any point throughout the height oi the window opening.
Another object is to provide a construction 20 which is positively locked in open position and which no amount of Wind or vibration of any kind imparted to the awning can accidentally trip the awning and cause its resultant collapse, this result being accomplished by the provision of a positive lock making it impossible to manually or accidentally trip the awning, until it has been moved along its guides to a predetermined tripping point.
With the general objects named in View, and others as will hereinafter appear, the invention consists in certain novel and useful features of construction and organization of parts as hereinaiter described and claimed; and in order that it may be fully understood, reference is to be had tc the accompanying` drawing, in which:-
Figure 1 is a perspective View of an automatic window awning of the invention with the fabric partially broken away to illustrate parts otherwise hidden.
Figure 2 is a side elevation of the awning as shown in Figure 1, illustrating in full lines the position of the awning when in preferred position with a tension on the awning fabric to remove all looseness out of the connections, and in dotted lines the maximum possible open-movement in the proportions of the parts illustrated, when the awning fabric is entirely slacked away and is not imposing any tension on the awning structure.
Figure 3 is a view in full lines of the awning in collapsed position, and in dotted lines of the position of the visor at the top of the window opening just prior to closing or just after opening movement.
Figure 4 is an enlarged disassembled View of the parts of the awning operating mechanism.
Figure 5 is a perspective View of an operating spring assembly forming part of the structure.
Figures 6 and '7 are views of modifications of detail parts of the awning mechanism.
In the said drawing, where like reference characters identify corresponding parts in all of the gures, l indicates the frame of a window opening, and secured at convenient points on opposite sides of the opening are a pair of upright guides 2, the lower ends of said guides providing stop portions 3, and their upper ends having trip portions 4, or any desired irregularity whereby certain brace locking members hereinafter identified may move out cf the plane of the guides, for example, the guide tripping portions may be as shown at 5 in Figure 6, it being understood that the essence of this invention lies in the provision of a positive locking member normally in contact with a predetermined suriace, and when moved out of contact with such surface or out of a predetermined plane, releasing the lawning arm for pivotal movement, and that many variations from the structure illustrated may be readily produced embodying the locking principle here involved, as distinguished from devices of the prior art usually tripped by contact with a projection as the awning is moved upwardly on its guides, it being apparent that such a trip Amay sometimes be operated by hand without moving the awning structure up to proper tripping position, or that on windy, gusty days, there is a possibility that such trips oi the prior art may be released by vibration.
Mounted for sliding movement along said guides are a pair of brackets 6 having upper and lower bosses 7 slidingly receiving the guides 2, and, where the structure is of the automatic adjustable visor type, the upper bosses '7 are connected by a visor bar 8 spanning the window opening, while a pair of awning arms 9 are pivotally secured to the lower bosses '7. The outer ends of the arms 9 are connected by an awning pole l), it being thus noted that the brackets 6 and their cross bar 8 respectively form an inverted U-frame sliding on the guide 2, while the awning arms 9 and their front or awning pole l0 form a second awning frame of generally U-shape mounted for pivotal movement, so that its upper end when in collapsed or folded position will preferably lie just below the plane of the visor bar 8, the parts being so proportioned that the awning frame will preferably, when folded, slightly incline outwardly from the vertical so that its gravitative tendency is always to swing down to open position. i
Mounted above the window opening and journaled in bearings 11 carried by the building front, is an awning fabric roller 12 on which a fabric 13 is rolled, the free end of the fabric extending down under the visor bar 8 and being connected at its end to the awning pole 10.
With the structure as thus far described, it will be apparent that when it is in open position there is nothing to prevent unlimited vibration of the awning pole by the wind, and that it will be impossible to position the awning at any desired point in the height of the window opening as the awning frame would immediately commence to collapse upon a rolling up of the fabric. To brace and positively lock the awning frame against collapse by vibration or even manual manipulation, short of rolling up the awning structure to a predetermined point, the following apparatus embodying the principle of operation heretofore mentioned, is employed:
The apparatus to be described, is preferably employed in duplicate at opposite sides of the window, but for convenience will be described in the singular as the structure may work efficiently with locking means at one side only.
Pivotally secured adjacent the inner end of the awning arm 9 at any desired distance from its pivotal mounting on the boss'7 of the visor frame, is a link brace or member 14, said brace extending upwardly and inwardly and being pivotally secured to the lower end of a second brace member 15, which in normal position, with the awning open, is in sliding contact at its rear side with the bracket 6. With this construction, it will be evident that strain on the fabric tending to pivot or collapse the awning frame will be transmitted to the brace members 14 and 15, the latter tending to slide upwardly within the bracket 6.
To prevent collapse of the brace a dog or locking member 16 in the shape of a bell-crank lever is pivotally mounted on the ends of the visor bar 8, said dog having at its opposite ends a pair of abutments 17 and 18 and being so proportioned that when the awning is open the abutment 17 is firmly held within a locking recess 19 in the upper end of member 15, due to the fact that the recess 19 is preferably beveled and pressure against abutment 17 is resisted by direct contact of abutment 18 against the predetermined plane or surface, in this case, against the guide 2. With the construction described, it will be evident that there is absolutely no chance of the awning collapsing, either through manual tripping or through vibration, as the abutment 17 cannot move out of the path of travel of the brace member 15 as long as its companion abutment 18 is in contact with the predetermined surface or plane, in this case, the guide 2.
When it is desired to collapse or fold the awning, the fabric is wound onto the roller 12 and the entire awning structure in open position is thus caused to slide upwardly on the guides 2, it being evident that as long as tension is thus applied to the fabric, pressure is transmitted against the abutment 18 tending to move it inwardly of the plane of the guide 2, and consequently immediately the abutment attains the tripping portion 4 of the guide, it permits rocking of the bellcrank dog 16 to remove the abutment 17 out of the locking recess 19 in the member 15, the brace is thus permitted to break, and the awning frame is free to swing upwardly to collapsed position upon the continued further rolling of the fabric on the roller.
It will be noted that as the locking member 16 passes inwardly of the plane of the guide 2, it operates as a retainer to prevent downward movement of the brackets 6 on the guides 2, and the weight of the entire awning structure is thus transferred from the fabric to the dog or lock 16 to hold the awning as the brace is broken and slack is provided in the visor portion. With the trip portion 4 of the guide 2 inclined downwardly and outwardly, it will be apparent that when the awning roller is permitted to revolve to unwind the fabric, the first movement is for the visor to be formed by downward gravitative movement of the awning frame and that when the visor is fully formed, the abutment 17 will snap into the notch 19, the companion abutment 18 coming into the planey of the guide 2, the weight of the structure being thus transmitted to the fabric. The operator may now unwind the desired amount of fabric to place the visor at any desired position of adjustment throughout the height of the window opening.
If the awning is permitted to gravitate downwardly until the bottom boss 7 contacts with the portion 3 of the guide, presuming that there is suflicient fabric available for such extended movement, it will be apparent that the weight of the awning structure will be assumed by the portions 3 of the bracket 2, and that under continued release of more fabric from the roller, the awning frame would swing beyond the horizontal until the brace 14 was stopped by contact with the pivot of the arm 9 on the lower boss 7 and might ultimately displace member 15. To avoid such operation of the parts it has been found desirable to out away the rear side of the brace member 15 as shown, to form a stop shoulder 20, which through contact with the upper surface of a pair of spaced ears 21 carried by bracket 6, prevents downward movement of the member 15 beyond such fixed range.
In Figure 7 a modified slide bracket 21a is illustrated, corresponding to the bracket 6, which is provided at its lower end with a horizontal eX- tension 2lb constituting a pocket to hold the awning arm 9 from moving below the horizontal. I'his construction obviously also prevents brace member 14 from assuming a pendant position and also obviates the use of a stop shoulder 20 on the brace member 16. Of course the maximum opening movement of the awning frame may be limited by providing fabric of such length that there shall be insuficient fabric to let the awning frame move downwardly beyond locking position, as will be readily understood.
To assist in the quick opening of the visor upon the release of the fabric from the roller, particularly if the awning frame in foldedl position is very close to the vertical, it has been found desirable to provide spring opening or resilient means to assist the gravtative tendency of the awning arm 9. As shown in this application, said spring means comprises a spring guide rod 22 secured to the rear side of the member 15 and encircled by an expansion spring 23, the upper end of said spring pressing against the underside of the ears 21, and its lower end against a shoulder 24 formed adjacent the lower end of the brace member 15.
From the above description it will be evident that I have described a construction embodying all of the features set forth as desirable. It is to be understood that I reserve the right to make all vchanges within the spirit of the invention and without the ambit of the prior art.
