The present invention relates to sealing structures between the perimeter of a door and a surrounding structure such as a doorjamb. In particular, the present invention relates to a sealing pad that is adjustably mounted to a bottom corner of a doorjamb.
In many building structures it is highly desirable to provide effective sealing action to prevent or limit contact between the bottom of a doorjamb with insects or moisture. Typically, a relatively compressible fibrous material or plastic or rubber material has been widely employed for this purpose, e.g. by applying the material to the bottom of the doorjamb, such as with an adhesive. This method, however, does not allow the sealing material (corner seal) to be adjusted after it is applied to the doorjamb. Adjustability of the sealing material may be necessary for several reasons. For example, many door jambs are installed unfinished; i.e., unpainted. To be able to paint the jambs, the sealing material is usually removed by the painter, but the adhesive sealing material cannot be reinstalled on the door jamb after painting is complete. Also, removal of an adhesively attached corner seal may cause the seal to become damaged during removal, possibly requiring a new seal Further, many door sill assemblies have an adjustable threshold cap, so that overtime as the house settles and the flexible sweep on the bottom of the door wears, the threshold cap may be adjusted to maintain a proper seal. The method of using adhesive to affix the corner seal does not allow it to be moved and adjusted as the threshold cap is adjusted, resulting in the corner seal being improperly positioned after adjustment of the threshold cap.
Therefore, there remains a need for a corner seal whose position on the doorjamb is adjustable after it is applied to the doorjamb and/or after the door has been permanently secured or removed and reinstalled.
An object of the present invention is to provide a sealing pad that is applicable to the bottom of a doorjamb to effectively seal it from insects and/or moisture. The sealing pad contains a base and at least three lobes formed on top of the base, an inside lobe closest to an inside edge of the sealing pad, an outer lobe farthest away from the inside edge, and a middle lobe in between the inside and outer lobes. Preferably, the thickness of the sealing pad increases from the inside lobe to the middle lobe to accommodate the swinging arc of the door, so that as the door swings to a close position, the leading edge of the door does not catch and stop or tear the sealing pad. The base contains a tail, preferably a barbed tail, at the inside edge opposing and extending away from the outside lobe.
Another object of the present invention is to provide a method for installing the sealing pad. The method involves inserting the tail into a channel in the door jamb and tucking the outer lobe under the adjacent weather strip. Because adhesive is not used to affix the sealing pad to the door jamb, the position of the sealing pad may be adjusted by sliding it along the channel and the weather strip.
Other aspects of the invention, including apparatus, devices, kits, processes, and the like which constitute part of the invention, will become more apparent upon reading the following detailed description of the exemplary embodiments.
The foregoing background and summary, as well as the following detailed description of the drawings, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there is shown in the drawings embodiments which are presently preferred. It should be understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown. In the drawings:
Referring now in more detail to the drawings, in which like numerals refer to like parts throughout the several views,
The vertical side jamb 12, which can be milled of wood, formed of extruded plastic, or be fabricated from a combination of materials, is configured to define a vertical support member 14 that forms a raised stop 16 with respect to an inset surface 18 of the vertical side jamb 12. The vertical side jamb 12 has an inside edge 19 that may be in contact with a decorative casing 21, such as a brickmold. In a typical installation, baseboard 22 may abut the bottom of the decorative casing 21.
A weather strip 17 (shown in
A sealing pad 27, configured according to the principles of this invention, is secured to the inset surface 18 of the vertical side jamb 12 at the bottom end thereof where the vertical side jamb meets the threshold cap 24. The sealing pad 27, described in greater detail below and as illustrated in
The sealing pad 27 may be formed from one or more flexible polymeric materials, e.g., by 3-D printing, extrusion, or injection molding. In one embodiment, the sealing pad 27 may be formed as a unitary piece. In another embodiment, the lobes 302, 304, 306 and the base may be formed separately and subsequently assembled, e.g. by adhesive, to form the sealing pad 27. The lobes 302, 304, 306 may be solid, hollow, or filled with a foam material. The material forming the base 300 and the lobes 302, 304, 306 may be the same or different. The materials may be selected, e.g., to provide sufficient rigidity to the base 300 and the tail 308 while allowing the lobes 302, 304, 306 to remain flexible. The tail 308 may be formed from the same material as the base 300 or a combination of the base material and the flexible lobe material, The polymeric material may be, but is not limited to, a thermoplastic elastomer, natural rubber, synthetic rubber, or combinations thereof.
As illustrated in
Although certain presently preferred embodiments of the invention have been specifically described herein, it will be apparent to those skilled in the art to which the invention pertains that variations and modifications of the various embodiments shown and described herein may be made without departing from the spirit and scope of the invention. Accordingly, it is intended that the invention be limited only to the extent required by the appended claims and the applicable rules of law.
