Measuring device for determining the seat height and seat inclination angle of chairs

Abstract

To provide a measuring device that allows a user to easily measure the seat height and seat inclination angle of a chair while experiencing it in order to adjust the seat height and seat inclination angle to suit the user's physical and preference requirements. [Solution] Steps 2 are installed on the chair seat height / seat angle adjustment device main body 1, and the user sits on the chair placed across the step boards, and the optimal height at which the sole of the foot touches the floor is measured by increasing or decreasing the number of step boards. The optimal inclination angle of the seat is also measured by placing the front or rear legs of the chair on the stepped adjustment mechanism part 3. By processing the chair according to the dimensions obtained by the measuring device of this invention, the user can use a chair that suits their body and preferences for a long period of time.

Description

[Technical field]

[0001] The present invention relates to a measuring device for determining the cutting dimensions of chair legs according to the user's physique, physical requirements and preferences. [Background technology]

[0002] It is known that if a chair does not fit the user's physique or preferences, it can cause physical and mental fatigue. As a countermeasure, sellers have traditionally cut the front and back legs of chairs to fit the user. However, the only measuring equipment available for this purpose is a number of thin boards that each seller prepares to place under the soles of the user's feet. Furthermore, there is no equipment to measure the seat inclination angle, and no proposals have been made yet. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] N / A

[0004] [Non-Patent Document 1] N / A Summary of the Invention [Problem to be solved by the invention]

[0005] By using the measuring device of this invention, each furniture store seller can more easily determine the seat height and seat inclination angle of the chair that suits the user's physique and preferences by experiencing it. By using a chair processed based on this data, the user can lead a comfortable daily life with a comfortable sitting posture. In addition, the chair can be re-measured and re-processed not only at the time of purchase, but also when the user's physical requirements change after a long time has passed since purchase, so that the chair can be used for a long time according to the user's changing physical requirements. [Means for solving the problem]

[0006] The user sits on a chair set up in the measuring device of this invention. Next, any number of footplates are placed under the soles of the user's feet, and the seat height that the user feels is optimal is determined based on the comfort of sitting on the chair and the feeling of the soles of the feet touching the ground. Furthermore, by cutting the front and rear legs to different dimensions, it is also possible to measure the adjustment dimensions for the seat inclination angle. Effect of the Invention

[0007] By using a chair that has been processed based on the values ​​derived by the measuring device of this invention, users can lead a comfortable daily life in a comfortable sitting posture. [Brief description of the drawings]

[Diagram 3] This is a diagram for determining the optimal forward seat inclination angle of a chair. [Figure 4] This is a diagram for determining the optimal backward seat inclination angle of a chair. [Diagram 5] This is a drawing for determining the optimal seat height as well as the seat inclination angle in the forward direction of the chair. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A step is placed on the chair seat height / seat angle adjustment device, and a chair is placed across the step. The chair is then seated and the optimum floor height for the sole of the foot is measured by increasing or decreasing the number of step plates. The optimum seat inclination angle is also measured by placing the front or rear legs on the stepped adjustment mechanism. EXAMPLES

[0010] An embodiment will be described below with reference to the attached drawings. First, each part in FIG. 1 will be described. Reference numeral 1 denotes the main body of the chair seat height / seat angle adjustment device, made from suitable materials such as wood or MDF board. A chair is placed on this and adjustment is made using the stepping board 2. 2 is a stepping board made of a wooden material. Reference numeral 3 is a stepped adjustment mechanism, which is used to determine the dimensions when cutting the front and rear legs to different sizes when determining the optimal seat inclination angle of the chair. Reference numeral 4 is a protective fence to prevent the user from falling over if the chair slips off 1 while adjusting the optimal seat height or seat inclination angle of the chair.

[0011] Figure 2 shows a method for determining the optimum seat height by cutting the front and rear legs of a chair to the same dimensions. The chair to be adjusted is placed at 1 and the user sits on it. Next, a step at 2 is inserted under the soles of the user's feet to determine the optimum number of steps. If one step is optimal, the height dimension of one step is the optimum dimension for cutting the chair legs, and if two steps are optimal, the height dimension of two steps is the optimum dimension for cutting the legs.

[0012] Next, we will explain Figure 3. This is a method for tilting the seat inclination angle of a chair forward. The chair to be adjusted is placed at 1, with the rear legs of the chair placed on the stepped adjustment mechanism at 3. There are many steps, and the higher the rear legs are placed, the more forward the seat inclination angle becomes. The user sits down and the optimal seat inclination angle is determined. If the optimal seat inclination angle is the second step of the stairs, then two of the treads at 2 are inserted under the soles of the user's feet and the comfort of sitting on the chair and the feeling of the soles of the feet touching the ground is checked. Figure 4 is attached showing how to tilt the seat back.

[0013] Fig. 5 explains how to find the optimal seat height after finding the optimal seat inclination angle. An additional step plate 2 is added under the soles of the feet of the seated user to check the comfort of the chair and the feeling of the soles of the feet touching the ground. The optimal seat height can be found while maintaining the previously obtained seat angle. [Industrial Applicability]

[0014] The measuring device of this invention is intended to be used when serving customers in furniture stores and the like, and to provide a chair that suits the user's body and preferences. [Explanation of symbols]
