The present invention claims the benefit of Korean Patent Application No. 2003-80813, filed in Korea on Nov. 15, 2003, which is hereby incorporated by reference.
1. Field of the Invention
The present invention relates to a hose clamping assembly, and more particularly, to a hose clamping assembly including a clamp and an arm connecting the clamp to another clamp.
2. Discussion of the Related Art
In general, a piping system is necessarily required for cooling a mechanical device or providing oil to the mechanical device in a mechanical system such as an automobile or an industrial plant system. The pipe is usually made of metal, resin or rubber.
In those piping system, many different types of elbows are used for connecting the pipes or switching a pipe direction, and sealing material such as bonds or sealant is used for sealing a junction of the piping system.
Meanwhile, a flexible rubber hose is generally selected for a piping system of a cooling system or an oil supply system of the automobile. The reason is because of a severe vibration and a narrow installation space of the automobile. That is, because the piping system of the automobile has to endure a repetitious vibration, the pipe is usually made of rubber and because there is not enough space in the engine room for the installation of the piping system, the flexible rubber hose is required for an easy installation.
To convert a flowing direction of the fluid in the hose or pipe, a branched pipe such as a T-shaped pipe or a Y-shaped pipe, for example, may be used. Many different methods to connect hoses to the branched pipe have been developed in the field.
Accordingly, the present invention is directed to a hose clamping assembly that substantially obviates one or more of problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide a hose clamping assembly in which an waste of molding material can be prevented by minimizing a clamp forming area and the hose can be more stably connected to a branched pipe by forming an arm connecting the clamp to another clamp adjacent.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, a hose clamping assembly comprises a branched pipe having a plurality of projected stoppers thereon, each of the stoppers formed around an outer surface of each branch of the branched pipe and spaced apart a certain distance from each other, a hose connected to each branch of the branched pipe by sliding onto each of the branches, the hose contacting a nearest stopper from the end portion of the branch among the plurality of stoppers, a clamp formed on an outer surface of the hose and between the stoppers by a molding apparatus, a portion of the clamp on the outer surface of the hose connected to a portion of the clamp between the stoppers, and an arm connecting the clamp to an adjacent clamp having a different axial direction, the arm formed by the molding apparatus.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention. In the drawings:
Reference will now be made in detail to the preferred embodiment of the present invention, which is illustrated in the accompanying drawings.
One end of the hose 200 slides onto the branch of the branched pipe 200 and then contacts the lateral surface of the first stopper 130a past the protrusions 120 as shown in the figure. Flexible material such as a rubber or a resin may be selected for forming the hose 200. A clamp 300 is formed on the hose 200 to cover a portion of an overlapped area between the hose 200 and the branch of the branched pipe 100 and a space between the stoppers 130. That is, the clamp 300 is formed on the hose 200 and the interval between the stoppers 130 at a time by a molding apparatus. As shown in the figure, the clamp 300 on a horizontal branch is connected to the clamp 300 on a vertical branch by the arm 400 that is formed at the same time together with the clamp 300 by the molding apparatus. That is, the arm 400 connects the clamp 300 to the clamp 300 having a different axial direction. Molding of the clamp 300 and the arm 400 can be done by any means known to those skilled in the field and it is desirable to adopt an injection molding method for the forming of the clamp 300 and the arm 400 in a single body.
In the fore mentioned embodiment, only one arm 400 is formed between the clamps 300 perpendicular to each other. However, the number of the arm 400 formed between the clamps 300 can be varied depending on the situation. That is, two arm 400, for example, may be formed between the clamp 300 and the adjacent clamp 300 having a different axial direction in order for the clamp 300 to secure a connection between the hose 200 and the branched pipe 100 more firmly and stably. Accordingly, even when one of the arms 400 is broken, the rest of the arm 400 can be used for connecting the clamp 300 stably.
The advantages of the present invention are as follows. First, the resin material for forming the clamp can be saved by molding the clamp and the arm only on an optimized area such as on a portion of the hose and the space between the stoppers. Secondly, forming the clamp and the arm in a single body by the molding apparatus can strengthen the connection between the hose and the branched pipe. Thirdly, the hose clamping assembly can have a more strong resistance against the twist of the hose by forming a plurality of the open-cuts in the stopper.
It will be apparent to those skilled in the art that various modifications and variations can be made in the array substrate for IPS mode liquid crystal display device and method for fabricating the same of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
