Pump seat for an inflatable product

Abstract

A pump seat for an inflatable product includes a hollow body with an open end. The body has a coupling portion formed at a side opposed to the open end. An opening is defined in the center of the coupling portion. A tongue is movably connected on the coupling portion for closing the opening. A finger is formed on the tongue and extends towards the interior of the hollow body. A recess is defined in the body beside the opening. A plug is selectively positioned in the opening or the recess. When an inflating process applied to the inflatable product is finished, the plug is inserted into the opening to provide a further airproof effect.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a pump seat for an inflatable product, and more particularly to a pump seat which can effectively prevent air leakage.

2. Description of Related Art

Large inflatable products made of rubber material, such as airbed or inflatable swimming pool etc., should be inflated and deflated with an electrical pump.

The inflatable products each have a seat for mounting the electrical pump. A valve is provided in the seat for connecting with a nozzle of the electrical pump. The valve includes a tongue formed therein as an airproof element. During inflating process, the tongue is pushed downwards to open the valve. When the inflating process is finished, the tongue can be returned back to close the valve to prevent air leakage.

However, the tongue may incompletely close the valve, and air in the inflatable product will leak out during use period.

Therefore, the invention provides a seat for an electrical pump to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a seat for an electrical pump which can completely prevent air leakage in an inflatable product.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1-3, a pump seat for an inflatable product in accordance with the present invention includes a hollow body (10) with an open end. A coupling portion (11) is formed on a side of the hollow body (10) opposed to the open end. An opening (12) is defined in the center of the coupling portion (11). A tongue (13) is movably connected on the coupling portion (1) for closing the opening (12). A finger (14) is formed on the tongue (13) and extends towards the interior of the hollow body (10). A recess (15) is defined beside the opening (12).

A plug (20), which can be received into the opening (12) or the recess (15), has two elastic handles (21) symmetrically and pivotally connected to the top of the plug (20). The plug (20) has a circular cross section. The elastic handles (21) can be pivoted downwards to a horizontal position, as shown in FIGS. 1 and 3, and can be pivoted upwards to a vertical position so as to conveniently remove the plug (20) from the opening (12) or the recess (15), as shown in FIGS. 2 and 4. When an inflating process to an inflatable product is finished, the plug (20) is inserted into the opening (12) to provide a further airproof effect.

During an inflating, deflating or in a non-using status, the plug (20) can be removed from the opening (12) and inserted into the recess (15), as shown in FIGS. 4 and 5. Thus, the plug (20) is stored appropriately and will not be lost.

With reference to FIGS. 6-7, the pump seat (10) is mounted on an inflatable product (30). During an inflating process, an electrical pump (40) is received in the hollow body (10). An inflating nozzle (41) of the electrical pump (40) is connected to the opening (12). The compressed air in the electrical pump pushes the tongue (14) downwards to open the opening (12) for inflating the inflatable product (30). In this case, the plug (20) is positioned in the recess (15).

When the inflating process is finished, the inflating nozzle (41) is removed. Under the air pressure in the inflatable product, the tongue (13) will be returned back to close the opening (12). Then, the plug (20) is removed from the recess (15) and inserted into the opening (12) to provide a further airproof effect, as shown in FIG. 8.

With reference to FIG. 9, during a deflating process, the plug (20) is removed from the opening (12) and a deflating nozzle (42) of the electric pump (40) is inserted into the opening (12). The finger (14) is pushed by the deflating nozzle (42) to open the opening (12), so the inflatable product (30) is deflated.

With reference to FIG. 10, an electrical pump (40) can be received in the hollow body (10) of the pump seat when the inflating nozzle (41) is inserted into the recess (15).

With the arrangement of the plug (20), air leakage can be completely prevented.

It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
