Minn.

Filed .lune 20, 1968, Ser. No. 738,685 Int. Cl. E05f 3/00 U.S. i Cl. 49-478 4 Claims ABSTRACT F THE DISCLOSURE An astragal for sealing the edge of a closure including a channel member, an astragal bar slidably engageable in the channel member, spring means in the channel, means carried by the astragal bar and engaging the spring means to normally urge the bar into a lixed relationship with the channel, the astragal bar having magnetic means for attracting the bar out of the fixed relationship with the channel together with means for limiting the outward movement of the astragal bar upon attraction of the bar by the magnetic means.

SUMMARY OF THE INVENTION The invention relates to an improvement in astragals used to weatherproof doors. It is an object of the invention to provide an astragal having a channel member for securement to the edge or face of a door and in the channel member is mounted spring means which engages an astragal bar normally urging the bar into a fixed relationship with the channel. The astragal bar has magnetic means thereon for attracting the bar Iout of the fixed relationship with the channel against the action of the spring means to effect a closure.

These and other more detailed and specic objects will be disclosed in the course of the following specication, reference being made to the accompanying drawings, in which:

FIG. l is a front elevational view of a pair of closed double doors on each f which is mounted an astragal embodying the invention.

FIG. 2 is a section on the line 2-2 of FIG. 1 showing the astragal bars in contact.

FIG. 3 is a section similar to FIG. 2 but with the doors and astragals separated slightly, the astragal bars held within the channel members.

FIG. 4 is a section on the line 4-4 of FIG. 2 with the astragal bars in magnetic engagement.

FIG. 5 is a section on the line 5-5 of FIG. 3.

FIG. 6 is a view of a portion of the channel on the line 6-6 of FIG. 3 with the astragal bar removed.

FIG. 7 is a perspective view of a retainer spring member removed from the astragal.

FIG. 8 is a perspective view of a retainer removed from the astragal.

FIG. 9 is a view on the line 9-9 of FIG. 4.

Referring to the drawings in detail, a pair of astragals A and B are shown mounted on the meeting edges of the doors C and D, respectively.

The astragals A and B are substantially identical except for left and right and as a result only A will be described in detail. The parts of B identical to those of A will bear the same reference numeral accompanied by a prime, thus The astragal A includes the elongated channel member 10 which includes the base portion =12 and the spaced side walls 14 and 16 extending therefrom. Extending from the base portion 12 and parallel to the wall 16 is the flange 18 which has formed therein spaced holes 20 adapted to receive screws 22 for securing the astragal to the door C. The numeral 24 designates a dovetail groove formed in and extending throughout the length of the base portion 12, the groove opening upon the inside of the channel member 10.

With particular reference to FIG. 8, there is provided a retainer member 26 formed of the body 28 having a cross section in the form of a trapezoid and adapted to snugly -fit in the groove 24 with the lip 30 extending from the top edge of the body thereof. The inside of the lip 30 is formed with the ramp portion 32 which terminates at its inner end in the shoulder 34. All of the retainer members are substantially identical but are accompanied by a different lower case letter. A lower retainer member 26a is secured in the groove 24 adjacent to but spaced from the lower end of the channel 10 with the lip 30 pointing downwardly. The retainer members 26 in each instance may be secured in the channel 10` by crimping out a portion of the channel in engagement with each end of the retainer as indicated at 36. An upper retainer member 26b is secured in the groove 24 adjacent to but spaced from the upper end of channel 10 with the lip 30 pointing upwardly.

Further provided are retainer springs 38 mounted in the channel v10 all of which are identical. Each spring 38 includes a at base portion 40, a central portion 42 extending from and angularly disposed to said flat base portion, said central portion terminating in an outer 4ilat leg portion 44 normally substantially parallel to the base portion, particularly FIGS. 5 and 6. A lower spring 38 is positioned in channel 10 with the base 401 secured to the bottom or base 12 of the channel by means of pins 46, the outer free end of the spring pointed upwardly and overlying the channel. An upper spring 38a is also positioned in channel 10 and spaced from the upper end of the channel with the base 40 secured to the bottom or base 12 by means of pins 50, the outer free end of the spring extending in an upward direction with the outer leg portion overlying the channel.

The numeral 52 designates an astragal bar which is substantially the length of the channel 10 and includes the elongated body 54 which has the longitudinally extending dovetail groove 56 formed in the inner face thereof. Secured in the dovetail groove 56 at the lower end by means of the Allen screw 58 is the lower removable retainer 26 with the lip 30 extending upwardly, particularly FIG. 4. When the astragal bar S2 is in operative position the lip 430 of the lower retainer 26c is in alignment with the lip of the retainer 26a in the channel 10. A lower intermediate retainer 26d is secured in the groove 56 spaced from the lower retainer 26C. An upper intermediate retainer 26e is secured in the groove 56 spaced from the lower intermediate retainer. Further provided is the upper retainer 26f secured in the groove 56 with the lip depending and spaced from the retainer 26e and adjacent the upper end of the bar '52.

The bar 52 has formed in the outer face thereof the longitudinally extending dovetail groove 60' in which is mounted the strip 62 of magnetic rubber by means of a dovetail connection. The magnetic rubber is known in the art and includes a composite of rubber or the like having associated intimately therewith particles susceptible to magnetization. This type of material is disclosed in U.S. Patent No. 2,999,275 on Mechanical Orientation of Magnetically Anisotropic Particles.

The astragal A is assembled in one manner by having the retainer 26c removed. The bar 52 is positioned so that the retainer 26f is above the retainer 26h with the retainer 26e above the end of the upper retainer spring 38a together with retainer 26d above the upper end of lower retainer spring 38. In this condition the bar 52 is moved or dropped longitudinally upon channel 10 whereby the lip 30 of retainer 26f is substantially opposite the lip 30 of retainer 26b and the upper end of spring 38a is in engagement with the shoulder 34 0f retainer 26e with the upper end of spring 38 in engagement with the shoulder 34 of retainer 26d, particularly FIG. 4. The retainer 26 is then secured in the dovetail groove S6 by means of the Allen screw 58 threadedly mounted in the body 54 and pressing the retainer against the flared walls of the groove. 'The lip 30 of the retainer 26e is substantially opposite the lip of retainer 26a, particularly FIG. 4. In this position the springs 38 and 38a contact the shoulders 34 of the retainers and bear slightly against the lips of the retainers 26d and 26e and normally urge the bar 52 into a xed relationship within the channel 10 and toward the base 12. It will be seen that with the above mentioned assembly of the bar 52 in the channel 16 there can be no displacement of the bar 52 relative to the channel due to the retainer members described.

With the astragals A and B in place on the faces of the doors C and D, respectively adjacent the edges, and the edges of the doors are placed or closed adjacent each other the magnetic attraction of the bars 52 for each other bring the same partially out of the channels and together against the action of the springs- The springs are formed of relatively weak thin stock, i.e., of such a resiliency that they yield to the attraction of the magnet bars 52.

In FIG. 5 the bar 52 is at rest within the channel 10 by means of the springs and not withdrawn by a magnetic bar of a companion astragal bar. It will be seen that the bar 54 can be displaced from the channel only to the extent as illustrated in FIG. 4 due to the retainer members 26f and 26o engaging 26a and 26b respectively. It will be seen that due to the springs 38 and 385L the astragal bar 54 remains substantially in the retracted position, except when in juxtaposition with a door frame or opposing door carrying a companion bar, thus allowing closure of the door to which the astragal is attached without the astragal bar striking the door frame or opposing door.

An astragal A may be placed on the frame of a door and the door having magnet attracting means thereon closed against the same. Also an astragal may be placed on a door with the frame having magnet attracting means which effects a seal when the door is closed. In a double swinging door two of such astragals may be used, one on the edge of each door where the same meet, so that the astragals contact each other when the doors are closed.

It is understood that suitable modications may be made in the structure as disclosed, provided such modiiications come within the spirit and scope of the appended claims. Having now therefore fully illustrated and described my invention, what I claim to be new and desire to protect by Letters Patent is:

1. An astragal for a door closure comprising:

(a) a channel member for securement to a door,

(b) an astragal bar slidably engageable in said channel member,

(c) spring means mounted in said channel,

(d) at least one first retainer member having a lip extending therefrom and carried by said astragal bar, said lip in engagement with said spring means whereby said astragal bar is normally urged into a xed relationship with said channel,

(e) said astragal bar having magnetic means for attracting said astragal bar out of said xed relationship with said channel and (f) a second retainer member carried by said channel member with said lip thereof engageable with the lip of said rst retainer for limiting the outward movement of the astragal bar upon attraction of said `bar by said magnetic means.

2. The device of claim 1 in which the magnetic means includes a strip of magnetic rubber.

3. The device 0f claim 2 in which said spring means is at least one leaf spring.

4. The device of claim 3 in which said second retainer is removably secured to allow positioning of said retainer of said astragal bar relative to said leaf spring.
