Benefits of technology

The present invention provides an overflow assembly for a bathtub that can be connected to different types of tubes and caps. This allows for the efficient and accurate connection of various components, ensuring proper functionality and safety during use.

Problems solved by technology

Therefore, the contact area between the between the nut and the hollow fitting is reduced, this may cause unstable connection.
Besides, the assemblers have to pay attention to avoid the overflow drain pipe inward from moving inward, this may reduce the efficiency of assembling.

Embodiment Construction

[0020]Referring to FIGS. 1 to 4, the overflow assembly of the present invention is to be connected to a bathtub 40 which includes an overflow drain pipe 10 in the wall behind the bathtub 40. The overflow assembly comprises an L-shaped head 15 which is connected to the overflow drain pipe 10. The head 15 has a flange 153 extending radially therefrom, and the flange 153 contacts the inside of the wall of the bathtub 40. A sleeve 154 extends from the end face of the head 15 and extends through an install hole of the wall of the bathtub 40. The sleeve 154 is perpendicularly connected to the flange 153. An opening 152 is defined in the head 15 and communicates with the overflow drain pipe 10. The sleeve 154 encloses the opening 152 of the head 15.

[0021]An adapter 20 is a circular part with a stepped outer surface, and the adapter 20 is securely mounted to the sleeve 154. The inner surface of the adapter 20 is matched with the outer surface of the sleeve 154. The sleeve 154 includes two t...

Abstract

An overflow assembly for a bathtub includes an overflow drain pipe which has a head, and the head has a flange extending radially therefrom which contacts the inside of the wall of the bathtub. A sleeve extends from the end face of the head and extends through an install hole of the wall of the bathtub. The head has an opening which communicates with the overflow drain pipe. An adapter is connected to the sleeve and secured to the head by bolts. A ring is engaged with the stepped outer surface of the adapter. A cap is mounted to the adapter, and the ring snugly contacts the inner surface of the cap.

Description

BACKGROUND OF THE INVENTION1. Fields of the Invention[0001]The present invention relates to an overflow assembly, and more particularly, to an overflow assembly for a bathtub wherein no threading connection is required when connecting the cap to the head of the overflow drain pipe.2. Descriptions of Related Art[0002]The conventional overflow assembly for a bathtub is used to prevent water in the bathtub from overflowing the bathtub and can be drained through the overflow assembly.[0003]U.S. Pat. No. 6,675,406 discloses an overflow assembly for a bathtub, and comprises an overflow port which has a flange and a sleeve that extends outwardly from the flange for receiving the inner end of a hollow fitting having an outer end and threads on an outer surface. A thin diaphragm seals the outer end of the fitting. A nut has a threaded center opening threadably mounted on the fitting to exert pressure towards the flange. The nut has an outer periphery with a series of radially extending lugs ...
