Actually, if the door design can take it, good old fashion "felt welting" on the jamb and door will create a much better draft proof lock to the elements East Dane Designer Men's Fashion.

No matter how much warmth is generated by your heaters or fireplaces , this heat will escape unless cracks and gaps in doors and windows are sealed with weather stripping.

  • Unfortunately, a door's weather seals, if it has any at all, can rip, compress, bend, or wear out over time, leaving chilly winter air free to enter or expensive air-conditioned air to leave.
  • Garage doors are very large, and while all come with a bottom seal to keep out water, wind, dirt, and unwanted intruders, the seals themselves can break down over time.
  • Perfect for a science project or at-home activity, making your own weather barometer is simple and lots of fun.

You can use weatherstripping in your home to seal air leaks around movable building components, such as doors or operable windows. Choose a type of weatherstripping that will withstand the friction, weather, temperature changes, and wear and tear associated with its location. For example, when applied to a door bottom or threshold, weatherstripping could drag on carpet or erode as a result of foot traffic.

Weatherstripping in a window sash must accommodate the sliding of panes -- up and down, sideways, or out. The weatherstripping you choose should seal well when the door or window is closed but allow it to open freely. Choose a product for each specific location.

Felt and open-cell foams tend to be inexpensive, susceptible to weather, visible, and inefficient at blocking airflow. However, the ease of applying these materials may make them valuable in low-traffic areas.

Guide to Home Weather Stripping | House Method

The present invention relates to a weather strip and specifically to a process for manufacturing the same. A body of an automobile is provided with a weather strip along a door opening. The weather strip may seal a clearance formed between the door and the body when the door is closed so that entry of raindrops and the like is effectively prevented.

As shown in FIGS. The weather strip W' is integrally formed and has a uniform cross-sectional configuration. The sealing portion Ws' of the weather strip W' has a groove 53 extending longitudinally therealong.

Therefore, a gutter G' is formed along the front pillar P' and the roof panel R' when the weather strip W' is mounted on the automobile body 4'. The gutter G' may lead rainwater from the roof panel R' to effectively prevent the rainwater from flowing toward a side window. However, the gutter G' extending along the front pillar P' may cause increase resistance of the air and increased sound emission therefrom during travel of the automobile.

The first section W"1 includes a first engagement portion Wa1" and a first sealing portion Ws1". The second section W"2 includes a second engagement portion Wa2" and a second sealing portion Ws2". As will be observed from FIGS. As shown therein, only the second sealing portion Ws2" of the second section W"2 has a groove extending longitudinally therealong.

Therefore, when the weather strip W" is mounted on the automobile body 4", a gutter G" is formed along the roof panel R" whereas no gutter is formed along the front pillar P". Such an irregularly shaped weather strip W" is manufactured by a process which comprises the steps of separately molding the sections W"1, W"2 by an extrusion procedure and subsequently bonding the sections W"1, W"2 at the ends thereof.

However, the irregularly shaped weather strip W" manufactured by the process exhibits undesirable awkward appearance because of a joining portion formed thereon. Further, such a process includes a large number of steps since the sections W"1, W"2 are separately formed, thereby causing increased working time and labor cost. Some improved weather strips and processes for manufacturing the same are found, for example, in Japanese Laid-Open Patent Publications Nos.

Each of the weather strips is an irregularly shaped weather strip which exhibits good appearance because of the absence of a joining portion. Further, each of the processes may permit continuous manufacture of the irregularly shaped weather strip. Therefore, these weather strips and the processes may to some extent solve the above-described problems. However, in each of the weather strips, the cross-sectional configuration of one section does not greatly differ from that of the other section.

Also, each of the processes does not permit formation of a weather strip including two sections of which the cross-sectional configurations are greatly different from each other. It is an object of the invention to provide an irregularly shaped weather strip including two sections of which the cross-sectional configurations are greatly different from each other.

It is another object of the invention to provide a manufacturing process which may permit formation of the weather strip including two sections of which the cross-sectional configurations are greatly different from each other.

According to the present invention, there is provided an irregularly shaped weather strip having first and second weather strip sections integrally formed as a unit, each of the first and second weather strip sections including a sealing portion and an engagement portion, the sealing portion and the engagement portion of each of the first and second weather strip sections being formed of different kinds of materials, respectively, the sealing portion of the first weather strip section having a cross-sectional configuration different from that of the sealing portion of the second weather strip section.

An important feature of the present invention is that the weather strip includes two sections of which the cross-sectional configurations are greatly different from each other. Another feature of the present invention is that the process may permit formation of the weather strip including two sections of which the cross-sectional configurations are greatly different from each other,.

Referring now to FIGS. Further, for convenience in terminology, the irregularly shaped weather strip will be called a "weather strip" in the following description. The weather strip W has a first section W1 and a second section W2 integrally formed with the first section W1. As best shown in FIGS.

The second section W2 includes a second engagement portion Wa2 and a second tubular sealing portion Ws2 integrally formed with the second engagement portion Wa2. The engagement portions Wa1, Wa2 and the sealing portions Ws1, Ws2 are generally formed of a semi-hard rubber and a sponge rubber, respectively. The first sealing portion Ws1 has substantially an oval-shaped cross-sectional configuration FIG.

Further, each of the first and second engagement portions Wa1, Wa2 has substantially a U-shaped cross-sectional configuration and is reinforced by a reinforcement bar 2 embedded therein.

The gutter G effectively guides rainwater from the roof panel R. However, since the first sealing portion Ws1 of the first section W1 has no groove, no gutter is formed along the front pillar P.

This may permit reduced sound emission during travel of the automobile. The apparatus includes a molding die The front end surface of the molding die 11 is formed with an opening The opening 12 has a configuration substantially corresponding to the cross-sectional configuration of an original first section W1' of an original weather strip W'.

As will be observed from these drawings, the original first section W1' substantially corresponds to the first section W1 of the weather strip W, provided that an original first engagement portion Wa1' is not bent to a U-shaped configuration in cross-section. The molding die 11 has a pair of conduits 13, 14 communicated with the opening The conduits 13, 14 are also communicated with a feed pipe not shown for feeding molten semi-hard rubber M1 and a second feed pipe not shown for feeding molten sponge rubber M2, respectively.

The apparatus also includes a hot air blower 15 and a pair of corresponding guide rollers 16a, 16b positioned in front of the molding die The blower 15 is arranged so as to move toward and away from a molding product extruded from the opening The blower 15 has a nozzle portion 15a longitudinarily extending along the molding product extruded from the opening The guide rollers 16a, 16b are arranged so as to guide the side surfaces of the molding product.

The molding product is used as the original first section W1'. The original first section W1' includes the first sealing portion Ws1 formed of sponge rubber and the original first engagement portion Wa1' formed of semi-hard rubber. In this step, the blower 15 is apart from the molding product and is turned off. This step is continued until the desired length of the original first section W1' is obtained.

When the hot air is blown, the portion formed of sponge rubber of the molding product is modified and is hardened at the same time, thereby to form an original second section W2' which includes the second sealing portion Ws2 formed of sponge rubber and an original second engagement portion Wa2' formed of semi-hard rubber. Further, to facilitate modification of the portion formed of sponge rubber of the molding product, grooves 3 can be longitudinarily formed on such a portion, as shown in FIGS.

Such grooves 3 can be easily formed on the portion formed of the sponge rubber by partly modifying the configuration of the opening 12 of the molding die As will be observed from these drawings, the original second section W2' as formed substantially corresponds to the second section W2 of the weather strip W, provided that the original second engagement portion Wa2' is not bent to a U-shaped configuration in cross-section.

In this step, the guide rollers 16a, 16b act as forming means for effectively preventing excessive deformation of the portion formed of sponge rubber of the molding product. Therefore, the second sealing portion Ws2 has a substantially predetermined cross-sectional configuration. Further, as will be appreciated, the original second section W2' is integrally connected with the original first section W1'.

This step is continued until the desired length of the original second section W2' is obtained. Thus, an original weather strip W' including the original first and second sections W1', W2' is continuously formed. Thereafter, the original first and second engagement portions Wa1', Wa2' are longitudinarily bent to a U-shaped cross-sectional configuration, thereby to form the weather strip W including the first and second sections W1, W2. Further, bending of the flat engagement portions Wa1', Wa2' is carried out by using a conventional bending machine not shown.

The molten sponge rubber used herein is of a vulcanized molten rubber containing a foaming agent. Such a molten rubber cures with a gas produced from the foaming agent contained therein, thereby to form the sponge rubber.

As will be easily understood, increasing the quantity of the gas contained in the sponge rubber will reduce hardness of the sponge rubber. Conversely, if the quantity of the gas contained in the sponge rubber is reduced for some reasons, the hardness of the sponge rubber will be increased, that is, the expansion ratio of the sponge rubber will be reduced.

Such a hot air may rapidly soften the sponge rubber to degas the sponge rubber. Therefore, as shown in FIGS. Some embodiments modified from the first embodiment will now be described with reference to the FIGS. The apparatus includes a forming roller 17 positioned between the blower 15 and the molding die The forming roller 17 is arranged so as to move toward and away from the molding product extruded from the opening The forming roller 17 has a peripheral edge of which the cross-sectional configuration substantially corresponds to that of the outer groove 1 of the second sealing portion Ws2.

The forming roller 17 engages the portion formed of sponge rubber of the molding product to modify the cross-sectional configuration thereof, thereby to form the original second section W2' which includes the second sealing portion Ws2 and an original second engagement portion Wa2'.

Thereafter, the hot air blown from the nozzle 15a of the blower 15 is applied on a part of the second sealing portion Ws2 to harden the same. As will be easily understood, since the hot air is used only to heat and harden a part of the second sealing portion Ws2, reduced air pressure can be used.

Further, an extreme infra-red ray heater can be used to heat and harden a part of the second sealing portion Ws2. Although the blower 15 is adapted to apply the hot air on a part of the second sealing portion Ws2, the blower 15 can be designed to heat all the portion of the second sealing portion Ws2 or all of the original second section W2'.

Further, the blower 15 can be adapted to be turned on even when the first original section W1' is formed, so that the hardness of the first sealing portion Ws1 is also enhanced.

The apparatus includes a forming roller The forming roller is positioned under the blower 15 so as to be heated by the hot air blown from the blower The forming roller is arranged so as to move toward and away from the molding product extruded from the opening 12 together with the blower The forming roller has a peripheral edge of which the cross-sectional configuration substantially corresponds to that of the outer groove 1 of the second sealing portion Ws2.

In this step, the blower 15 is turned on for preheating the forming roller The forming roller engages the portion formed of sponge rubber of the molding product to modify the cross-sectional configuration thereof, thereby to form the original second section W2' which includes the second sealing portion Ws2 and an original second engagement portion Wa2'.

As will be easily understood, since the forming roller is previously heated, the forming roller may modify the portion formed of sponge rubber of the molding product and may simultaneously harden the same. In this embodiment, the blower 15 is used only to preheat the forming roller Therefore, the blower 15 can be replaced with a desired heating means not shown which is assembled to the forming roller The preferred embodiments herein described are intended to be illustrative of the invention and not to limit the invention to the precise form herein described.

They are chosen and described to explain the principles of the invention and their application and practical use to enable others skilled in the art to practice the invention. Effective date : Year of fee payment : 4. An irregularly shaped weather strip having first and second weather strip sections integrally formed as a unit.

Each of the weather strip sections includes a sealing portion and an engagement portion. The sealing portion and the engagement portion of each of the weather strip sections are formed of first and second molding materials, respectively. The sealing portion of the first weather strip section having a cross-sectional configuration different from that of the sealing portion of the second weather strip section. Such a weather strip is manufactured by extruding the first and second molding materials.

The sealing portion of the second weather strip section is modified by blowing hot air at a portion of the first molding material.
