The present disclosure is generally related to pipe connection joints with flexible function.
Piping is used in many industries for many different applications, including piping as it relates to the installation and connection in residential and commercial buildings, walkways and landscapes, and other environments of piping for channeling water, wastewater, or other liquids and gases. In a typical installation, segmented piping is channeled throughout a structure or substrate and connected, segment to segment, using fixed straight or fixed angled joints and connectors to complete the network of piping that is intended to distribute a liquid or gas from a source to one or more desired locations throughout the structures or substrates. Oftentimes, at a particular connecting point where pipe segments are joined to form a specific angle, the actual angle may be slightly off from the fixed, or rigid, angle of a standard joint. In this case, the installer needs to stress the rigid joint or segments of pipe to insert and affix pipe segments to the joint.
In one embodiment, pipe connection joints are constructed using two materials, a flexible material and a rigid material, which are fixedly attached to form a pipe connection joint that provides a few degrees of flex to allow for mis-alignment of pipe ends and to reduce stress at the joint. The flexible pipe connection joints are made in a variety of nominal angles, configurations, and sizes and each of the individual pipe connection joints can be flexed in any direction a few degrees from the nominal angle.
Many aspects of certain embodiments of the invention can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present invention. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The present invention relates to pipe connection joints that are constructed to provide a few degrees of flex and that are affixed to pipe ends using conventional affixing means, such as primer and pipe adhesives and other means. In particular, certain embodiments of the present invention include pipe connection joints that are constructed of at least two materials, a rigid material and a flexible material. The rigid material forms the connecting end portions of the flexible pipe connection joints and the flexible material forms the middle portion of the flexible pipe connection joints.
Digressing briefly, as explained above, in a typical installation, segmented piping is channeled throughout a structure or substrate and connected, segment to segment, using fixed straight or fixed angled joints and connectors to complete the network of piping that is intended to distribute liquid or gas from a source to one or more desired locations throughout the structures or substrates. Oftentimes, at a particular connecting point where pipe segments are joined to form a specific angle, the actual angle may be slightly off from the fixed, or rigid, angle of a standard joint. In this case, the installer needs to stress the rigid joint or segments of pipe to insert and affix pipe segments to joint. To address this and/or other connection challenges, certain embodiments of a flexible pipe connection joint as disclosed herein that can flex a few degrees in any direction so that the joint connection is de-stressed. In one embodiment, a flexible pipe connection joint includes flexible joints wherein a portion of the joint is a flexible material that is molded or attached fixably to portions of the joint that are rigid. The rigid portions are of similar material and sizing to accommodate standard affixing means, such as epoxies, primers, glues, and/or other bonding substances. Evidence of this relatively common need for joint connection flexibility exists in the marketplace. For instance, there are flexible fittings and joints made of a rubber or other substance that are used to join segments of pipe. However, these flexible fittings and joints use a clamping mechanism to seal the pipe ends from leaks. In contrast, certain embodiments of a flexible pipe connection joint enable the use of standard affixing means, such as using standard adhesives.
Having summarized certain features of a flexible pipe connection joint of the present invention, reference will now be made in detail to the description of a flexible pipe connection joint as illustrated in the drawings. While a flexible pipe connection joint will be described in connection with these drawings, there is no intent to limit it to the embodiment or embodiments disclosed herein. For instance, the illustrations and descriptions of the disclosed flexible pipe connection joint are not intended to be limiting, as there are a number of different configurations that might be utilized to achieve the utility of flexibility, usability, and joint stress reduction brought by the present invention according to variations that are contemplated to be within the scope of the invention as would be appreciated by one having ordinary skill in the art. Note that one or more features described for one embodiment may be combined or replaced with one or more features of other embodiments. Further, although the description identifies or describes specifics of one or more embodiments, such specifics are not necessarily part of every embodiment, nor are all various stated advantages necessarily associated with a single embodiment or all embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents included within the scope of the disclosure as defined by the appended claims. Further, it should be appreciated in the context of the present disclosure that the claims are not necessarily limited to the particular embodiments set out in the description. Like-numbered reference numbers refer to the same or similar components.
