RU184459U9 - LOCALLY INCREASED PRODUCT THICKNESS DEFECTOR - Google Patents

Abstract

The inventive utility model relates to assistive devices placed on window openings of vehicle doors.

The inventive utility model is aimed at solving a technical problem, which is to ensure the spillability of the product while reducing its thickness.

The inventive utility model allows to achieve two technical results, combined by a causal relationship, expressed in reducing the cost of the product by reducing the amount of material required in the manufacture of products and in ensuring the proper strength and performance of the product while reducing its thickness.

The technical problem is solved, and the technical result is achieved due to the fact that the deflector is made of sheet plastic and consists of a base, a stiffener and a shoulder. The bead locally increases the thickness of the product, which ensures the penetrability of products with different base thicknesses from 1.2 mm to 2.0 mm. In addition, the shoulder acts as a stiffener, providing the proper strength and performance of the product while reducing its thickness.

Description

The inventive utility model relates to assistive devices placed on window openings of vehicle doors.

An analogue of the claimed utility model is the side visor of the rear window of a vehicle according to US patent No. 20133334837 (A1), published on 12.19.2013.

An analogue is registered with the following formula.

A side window visor, comprising: a visor body having an upper length corresponding to the length of the sealing gum of a vehicle window from a front to a rear edge of a window; many reeds extending along the entire length of the upper part of the visor body, and many reeds are separated from each other by gaps; and adhesive tape along many reeds.

An analogue, like the claimed utility model, contains a visor body.

The design of the closest analogue has the following disadvantages:

- in the manufacture of products by injection molding, the thickness of the visor body may not be less than 0.07 inches (1.8 mm);

- there are no structural elements that increase the strength of the product (stiffeners).

Thus, the design of the analog does not provide the proper strength and operational characteristics of the product, with its thickness of 1.8 mm, and even more so with a decrease in thickness.

The prior art "Method and device for injection molding thin-walled parts under essentially constant pressure" according to patent RU No. 2575905, the date of publication of the application on June 27, 2015, which has several disadvantages:

The first is that the achievement of high filling speeds requires the application of high power, which requires the use of complex and accordingly expensive molding equipment. Moreover, most electric presses do not develop enough power to provide such high filling speeds, or require very complex and expensive drive systems, which significantly increases the capital cost of molding equipment, and makes such production of parts economically disadvantageous.

A second disadvantage is that high filling speeds require very high pressures. The application of such high pressures requires, in turn, the use of very high clamping forces to keep the mold tightly closed during filling, and such high clamping forces make the design of molding equipment very expensive. High injection pressures also require the use of high-strength molds, usually made of hardened tool steels. Such high-strength molds are also very expensive to manufacture, and using them to mold many types of parts may not be economically feasible.

The inventive utility model is aimed at solving a technical problem, which is to ensure the spillability of the product while reducing its thickness.

The inventive utility model allows to achieve two technical results, combined by a causal relationship expressed in reducing the cost of the product by reducing the amount of material required in the manufacture of products and in ensuring the proper strength and performance of the product while reducing its thickness.

The technical problem is solved, and technical results are achieved due to the fact that the deflector is made in the form of an integral structure of sheet plastic and consists of three structural elements:

- the central part (hereinafter referred to as the base) is a smoothly curved plate element;

- to the upper and one of the sides of the base there is a flanging in the form of a strip that acts as a stiffener;

- on the underside of the base there is a shoulder acting as a local increase in the thickness of the product to improve spillability and stiffeners.

To date, the applicant and the author of the claimed utility model - M. Stroykov made deflectors without collar up to 2 mm thick inclusive. Deflectors with a thickness of less than 2 mm have unsatisfactory performance, as turned out to be easily susceptible to deformation, fractures during storage, transportation, operation, as well as vibration under the influence of air flow when the vehicle is moving.

Placing a shoulder in the lower part of the product, which plays the role of a local increase in the thickness of the product to improve spillability and stiffeners, while maintaining the pressure in the gate system and the mold-forming damage of the mold, as well as maintaining the working cycle time, made it possible to ensure spillability of products of various thicknesses from 1.2 mm to 2 mm, while deflectors with a thickness of less than 2 mm have high performance characteristics.

In the particular case of the implementation of the utility model to further increase the spillability of the product to the recess of the punch forming the flange, an inlet gate is supplied.

In the particular case of the implementation of the utility model, the bead is placed above the lower end side of the product with the formation of an edge.

In the particular case of the implementation of the utility model, the shoulder is made with separation into several parts, with gaps between them, and an inlet gate is supplied to each part of the recess of the punch forming the corresponding part of the shoulder.

These signs form a stable set of essential features sufficient to obtain the desired technical result.

The essence of the utility model is illustrated by drawings:

FIG. 1 3/4 rear view;

FIG. 2 sectional view;

FIG. 3 special case of the execution of the deflector. The stiffener is made above the end side of the product;

FIG. 4 special case of the execution of the deflector. The stiffener is divided into several parts.

The inventive utility model is intended to improve ventilation of the vehicle interior and to prevent precipitation from entering the cabin when the windows are open.

The implementation and use of the claimed utility model is achieved with the achievement of two technical results, combined by a causal relationship expressed in reducing the cost of the product by reducing the amount of material required in the manufacture of the products and in ensuring the proper strength and performance of the product while reducing its thickness, due to that the product consists of a base (1), an upper stiffener (3), a shoulder (2). The shoulder can be made with a different combination of height and width ranging from 0.6 mm to 1.8 mm. In a particular case, an inlet gate is fed to the recess of the punch forming the shoulder. In the particular case of the implementation of the utility model, the lower stiffener is placed above the lower end side of the product with the formation of an edge. In the particular case, the shoulder is made with separation into several parts, with gaps between them (4), an inlet gate is supplied to each part of the recess of the punch forming the corresponding part of the shoulder.
