Abstract

A handle retention mechanism for a generally u-shaped handle ( 18 ) attached to a vessel ( 10 ) is formed by a hinge pin ( 42 ) connected to each of the handle ends, wherein each pin ( 42 ) is received in a bracket ( 34 ) mounted to the vessel ( 10 ) in a manner that allows each pin ( 34 ) to be retained in a first position in the bracket permitting rotation, and a second position in the bracket ( 34 ) prohibiting rotation, wherein a spring ( 54 ) biases the handle ( 18 ) into the second position and is designed for one-handed actuation to the first position for rotation.

Description

Pivoting handle retention mechanism

Technical field

But the present invention relates to have apparatus, article or the container of pivoting handle, and more specifically, relate to and be used for handle remained on the fixed position otherwise mechanism that described handle can freely pivot.

Background technology

Various known apparatus, article and container all have handle, and it is designed to pivot between two or more positions.Cooking utensils such as electric tea pot or non-electric tea pot and suitcase and briefcase also have all or other devices or article, has pivotable handle, it is removable easily so that can carry out various tasks and function, this moment handle otherwise can hinder or stop such task.Cooking utensils and container such as teapot and jar have pivoting handle, and it is placed on the top of container, and placed in the middle about quality, so that can mention container.Sometimes be such situation: lid or other lane devices (access means) are positioned near the handle by this way: be necessary or need pivoting handle with the road of door or lane device not.Design is used for being pivoted to a side or opposite side, still this is needed in addition the center be used for the normal handle that uses, and is oriented usually, so that gravity can make handle pivot and land from the center.This can cooperate and check by have simple friction in the bonded assembly hinge fraction of container at handle, but is is often worn and torn and fault, and/or need bimanualness to come the reorientation handle.Complicated locking mechanism also also can add cost with the needs bimanualness.When the container such as teapot is awfully hot, for safety and comfortable reason, wish to keep handle away from container (that is being in upright middle position), and it is remained there, minimize so that make from the transfer of heat of internal tank to handle.

Summary of the invention

Target of the present invention provides the handle retention mechanism that is used for pivoting handle, and it is designed to handle is remained on stand up position, and preferably reorientates easily and easily by one-handed performance.Further target of the present invention is the shortcoming that overcomes such prior art as discussed above.

These and other target realizes by the present invention.

According to the present invention, be used to be connected to the handle retention mechanism of handle of the common U type of container, form by each the link pin that is connected in the handle end, wherein, each pin is received in the support (bracket) that is installed to container by this way: allow each pin to remain on support and allow the primary importance of rotation and support to forbid the second place of rotating, wherein, spring is displaced to the second place with handle, and is designed to one hand and is driven into the primary importance that is used to pivot.

The specific embodiment

With reference to figure 1-12, kettle (10), it can be (usually known type) electric kettle, as showing, is used to use electric energy to come heating liquid, has main body (12), is used to keep hot liquid and/or is used to heat wherein liquid.Lid (14) removably is installed on the main body (12), and is removed and is used for liquid filling kettle (10) or is used for cleaning.In representative type uses, by Hu Zui (16) discharged liquid from kettle (10).

According to the present invention, the handle (18) with two ends (20,22) is pivotably connected to kettle (10).Hinge component (24,26) is positioned on each end (20,22).Each hinge component (24,26) is equal to, and thereby will only carry out reference to one in this is described.

Hinge component (24), it is equal to another hinge component (26), has mounting flange (28), is used to be installed to kettle (10).Provide a pair of rivet (30,32) or fastener hole to be used for installing.Holder part (34) is extended from flange (28) with such angle, so that holder part (34) is vertically extended usually.Pan (36) is provided, and it has wide diameter part (38) and non-circular narrow diameter part (40).

Each handle end (20,22) has hinge collar (40), and it extends therefrom, is connected to non-circular wheel shaft (42) and axle cap (44).Preferably wheel shaft (42) is shaped as cross-sectional plane and has one or more flat surfaces (46,48), and it is corresponding to the flat surface (50,52) in the pan (36).Can use other suitable geometric configuratioies, as long as wheel shaft (42) is prevented from pivoting when partly (40) are middle when being received in narrow diameter.

Handle end hinge component (24,26) so is inserted in the holder part (34), so that wheel shaft (42) through hole (36), and remains on wherein by cap (44), described cap (44) has the bigger diameter of maximum gauge than hole (36).

Spring (54) is connected to holder part (34) via jut (56,58), and has recessed centre portion (60).Spring (54) is reserved size or configuration, so that the part of the wide diameter in its overlapping hole (36) part (38).This conflicts with wheel shaft (42) when wheel shaft (42) is positioned in the wide diameter part (38), thereby wheel shaft (42) upwards is offset, so that the hole of the partial tooth engagement at least flat surface (50,52) of its flat surface (46,48).In this position, stop wheel shaft (42) to pivot, and thereby stop whole handle (18) to move about kettle (10) about hole (36).So, handle (10) just upwards is displaced in the non-pivot position.

In use, in the time of when handle (10) perpendicular positioning that is in non-pivot position, as shown in Figure 2, it is owing to the biasing force of spring (54) remains on that position, described spring (54) is aimed at the hole of partial sum at least (36) of the smooth part of wheel shaft, and is as explained above.When hope with handle (10) when moving to either side, such as near lid (14) or for other reason, the user catches handle (18) and applies power vertically downward, and spring force is overcome, so that handle (10) moves on the direction of vertical arrows (62).Move towards wide diameter part (38) from narrow diameter bore portion (40) by wheel shaft (42), help moving.This can be an one-handed performance, because kettle (10) can be shelved or be supported on the surface of stability (not shown) such as desk or heater element.In case vertical shifting takes place, it is enough to wheel shaft (42) is placed wide diameter bore portion (38), and wheel shaft just can freely pivot, and moves up the indicated either party of curved arrow (64).Can use various devices to stop excessive pivotal, comprise and use shoulder (66,68) to stop the surface, be pivoted to predetermined extent then contact handle (18) if this stops the surface to serve as.

Although described preferred embodiment, can change and do not depart from the scope of the present invention at this.And then handle keeps and the novel feature of pivot is not limited to use with kettle, but can use with multiple article and device.
