Abstract

The invention relates to a bathroom scale equipped with a base portion (1) arranged on base such as ground, and a support surface (3) for user to stand on. The bathroom scale has a monitor (6) for displaying user's weight and sensor element (5) for sensing user's weight. The support surface has an upward gibbous protrudent surface for accurately location of user's mass centre.

Description

A kind of Bathroom scales

Technical field

The present invention relates to a kind of Bathroom scales, this scale comprises and is placed on suprabasil body portion, and user's stayed surface on it of standing shows the display of user's weight and the sensor element of induction user weight.

Background technology

Scale, particularly Bathroom scales, known have countless different kinds.Scale mainly is mechanical, and simulation shows user's weight, or numeral, numeral shows user's weight.

It is smooth that the stayed surface of scale is compared with the substrate thereon of scale position.When the people who wants weighing oneself stood on the scale, where this people of indication explanation did not stand in.This just makes the people who is weighed often can not locate own exactly and oneself center of gravity, for example away from the weight induction element of scale edge or the corner towards scale.The inaccurate location of user's center of gravity makes scale can not show measurement result accurately.

Digital scale shows that the degree of accuracy of measurement result is usually above mechanical scale.If measurement result shows that with 10/1000ths degree of accuracy the inaccurate location of user's center of gravity can produce corresponding to difference several 10/1000ths and measurement result demonstration so.This is also unsatisfactory, all obtains a measurement result accurately when using scale because purpose is each user.

EP 1304552 A1 formerly disclose a kind of Bathroom scales device, and it can also measure by the person's of weighing health fat or thin except function of weighing.Back one function needs to electrically contact preferably between scale stayed surface and the user's pin.At last, the central area of stayed surface with a bowl-shape arch that raises up promptly mainly is rotational symmetric domes and flat edge portion is thereabout divided peripheral.This bow-shaped structural is so small, and the below only can obtain to electrically contact the time so that it is sitting at user's arch at least in part.

Effect is not corrected to the position of scale user supposition in the peripheral central area of bowl-shape or part, does not have effect especially near the axis of symmetry of bowl.

Summary of the invention

Structure of problem

Show by introduction, the objective of the invention is to design Bathroom scales to eliminate defective of the prior art.Especially, the objective of the invention is to design Bathroom scales so that they comprise the device that is used for the accurate location of user with respect to Bathroom scales weight induction sensor element.

Solution

If the Bathroom scales that shows by introduction is characterized in that stayed surface has the center of gravity that the convex surfaces that upwards overarches is located the scale user, will obtain becoming the purpose on basis of the present invention so.

Description of drawings

The present invention will obtain more detailed introduction with reference to accompanying drawing hereinafter.In the accompanying drawings:

Fig. 1 is the side view of Bathroom scales device that has the display of lifting;

Fig. 2 is the top plan of Bathroom scales device.

Embodiment

In the following description, will use such as representing direction and position forward, backward, up and down.This situation about relating to be when the use of man-hour scale of weighing according to the present invention be standard.

Fig. 1 represents to have the Bathroom scales of body portion 1, and this body portion is positioned in the substrate 2 such as ground.Scale also shows stayed surface 3, the user of scale stand in surface-supported above.See from above, stayed surface 3 is rectangle (although the angle can be round), be the convex surfaces that upwards overarches on Z-direction, this will be explained in further detail hereinafter that stayed surface 3 has been realized the accurate location with respect to the scale user center of gravity of the sensor element 5 of scale.Sensor element 5 induction balance users' weight.

The demonstration of user's weight is to realize by display 6.

Stayed surface 3 has device 4, and it is with respect to the sensor element 5 that is arranged in the scale leg 7, is accurately to locate him on the X-direction at scale user's horizontal direction.This people's of use scale horizontal direction is meant the direction of two shoulders of this people.

Stayed surface 3 is bent upwards simply along the bending axis that extends at horizontal direction (X-direction among the figure) basically.This just means that stayed surface has a horizontal ridge that is directed upwards towards in its central area (on Y direction), and it preferably extends on the X-direction between stayed surface 3 opposed side edge continuously.In the front and back of ridge, stayed surface 3 has the inclined surface part, and they show sizable inclination (15-30 °) with respect to substrate 2, and this enough causes station people's thereon uncomfortable feeling.These inclined surfaces can almost be the plane or arch.

The sagitta on arch support surface 3, be sizable promptly at the ridge top with by the distance on the vertical direction between the plane of surface-supported leading edge line and back edge line definition, be in distance between these edge lines 10% and 30% between the state of the size between 15% and 20% preferably.

Under the help of the domes of stayed surface 3, the user on stayed surface 3 along Y-axis accurate location on depth direction.

If the user on the scale stands too forwardly (in the front of surface-supported flexure plane 8, display is in his or her front) on positive Y direction, the user just just stands on the inclined surface.This feels uncomfortable, because the user of scale experiences a kind of sensation of falling down forward, if after the leaning on very much of user station, in the back of surface-supported flexure plane 9, display 6 is in his or her front, the user stands on the inclined surface.This also feels under the weather, because the user experiences a kind of sensation of falling down backward.Unconsciously, use the people of scale will adjust his/her position.

Stayed surface 3 can form or form by other device by compression moulding, bending, injection moulding, casting.Stayed surface 3 preferably is processed into by plastics or metal.

Display 6 component devices 4, the purpose of device 4 are the pin of accurately locating the user in a lateral direction the user.Device 4 also can be the dissimilar antiskid coverture that is placed on the surface 3.The antiskid coverture can hint by its location on stayed surface 3 user is placed on pin where.

The antiskid coverture can be the non-skid band that has rough surface, and rough surface is the danger that reduces to slip under the situation about wetting at supposition user's pin.The antiskid coverture also can be made up of the raised or sunken of stayed surface 3 of forms such as button, groove.

Display 6 is along leading edge 10 centralized positionings straight and basic horizontal of scale.When the user stood on the scale, in order to have the free visibility that can read measurement result, a pin stood in one side of display 6, inferred that the location of pin is also just simple.

Display 6 can rise to the position of conveniently reading as shown in Figure 1 from its lower position that flushes with arch support surface 3, wherein display 6 is level basically.

As shown in Figure 2, see that scale is aforesaid to be rectangular configuration, in order to obtain in each angle that reliable measurement result sensor 5 is positioned at scale from above.

Select the description of embodiment

Stayed surface 3 also can be two arches, and it can be realized by bending while curved surface on both direction.
