Abstract

The volume changeable draw-bar traveling case includes one case possessing telescopic hand bars with locking mechanism and caster wheels; and one square telescopic barrel with one end connected to the case and possessing a cover on the other end, barrel telescoping rods with fixed end on the case and movable end on the barrel. The telescopic barrel is made of flexible material and is provided with parallel square hard rings or spring frames and ferrules around the barrel telescoping rod. The volume changeable draw-bar traveling case has small volume when the telescopic barrel is in closed state or great volume when the barrel telescoping rods are elongated. After the barrel telescoping rods are elongated, the ferrules can fix the telescopic barrel well to protect held articles.

Description

A kind of bar traveling box

Technical field

The present invention relates to a kind of suitcase, especially relate to a kind of bar traveling box that can change volume as required.

Background technology

Bar traveling box great majority in the market all are that internal cavities is changeless, and its main material is the hard type of property injection mo(u)lding once, also have with flexible materials such as cloth, leathers and do decorative cover, and the inside is bumped into that hard plastic sheet makes.The draw-bar box that the Chinese patent communique discloses a kind of variable volume is " a folding pull bar bag ", the patent No. is CN97229289.6, it is a kind of structure that two relatively independent casings couple together by draw-in groove, and the improvement of this product mainly is for the ease of collection.The case and bag that also have several variable volumes in addition, as the patent No. be " folding traveling bag ", the patent No. of ZL97126183.0 be CN90104629.9 " telescopic leather trunk ", " expandable luggage " that the patent No. is CN89108375.8, to also have the patent No. be CN95194213.1 " variable-displacement chest ", but the volume that they can change little or use convenient inadequately; The method that many change trunk internal volumes are also arranged abroad, project organization is that a less case section of opening section is advanced in the bigger case section of opening section with end to end mode intussusception, its shortcoming is to make more complicated, and the perisporium of two case sections must be solid relatively.

Summary of the invention

Purpose of the present invention just provides a kind of bar traveling box that can significantly change the draw-bar box volume easily.

For achieving the above object, bar traveling box of the present invention comprises the telescopic hand lever that with locking mechanism is housed, the casing of castor, it is characterized in that: its other end of telescopic barrel body that an end is provided with cover is connected the upper end or the lower end of casing; Other has telescopic barrel body telescopic lever, and fixedly rod end and flexible rod end are separately fixed on casing and the telescopic barrel body for they.

Described hand lever and telescopic lever are the case and bag telescopic pull rod device of prior art, constitute by fixed bar and expansion link, fixed bar or expansion link one end link to each other with casing, the close cover end of the other end of expansion link or fixed bar and telescopic barrel body or directly link to each other with cover, locking mechanism is arranged in the fixed bar, behind the operating key of pinning on the bar handle, expansion link can be pulled out, unclamp button then expansion link be locked in and pull out extension position; Both sides or the back side, both sides and the back side that described scalable idler arm is arranged on scalable draw-bar box are provided with simultaneously.

On above-mentioned basic structure basis, following several concrete structure can be arranged:

Described telescopic barrel body is in the lower end of casing, bottom half perforate with telescopic barrel body junction, the telescopic barrel body communicates with the inner chamber of casing, casing is provided with opens lid, cover on the telescopic barrel body is that hard material is made, hard type tube lid becomes the base that draw-bar box is installed castor, and the flexible rod end of scalable idler arm is fixed on the casing side, and fixedly the rod end other end is fixed on the hard type tube and covers.

Described telescopic barrel body is in the upper end of casing, all is provided with on casing and the cover to open lid, and the fixedly rod end of scalable idler arm is fixed on the casing side, and the expansion link other end is fixed on the cover on the telescopic barrel body or the upper end of perisporium.

Described telescopic barrel body is in the upper end of casing, casing top drilling with telescopic barrel body junction, all be provided with on casing and the cover and open lid, the fixedly rod end of scalable idler arm is fixed on the casing side, and the expansion link other end is fixed on the cover on the telescopic barrel body or the upper end of perisporium.

Wherein, the perisporium of telescopic barrel body can be designed to following four kinds of situations respectively:

Described telescopic barrel body is the square tube shape that perisporium is made with flexible material.

Described telescopic barrel body is the square tube shape that perisporium is made with flexible material, and a plurality of parallel square hard rings are housed on the perisporium, on by scalable idler arm square hard ring on one side, is fixed with the ring that is enclosed within on expansion link or the fixed bar.

Described telescopic barrel body is the square tube shape that perisporium is made with flexible material, and square spiral spring-like framework is housed on the perisporium, is with ring on the expansion link of telescopic lever and/or the fixed bar, and its outer is connected the coil spring shape leg of frame.

The perisporium of described telescopic barrel body is the square tube shape that flexible material is made, be equipped with on the perisporium the front and back of casing or about respectively be added with the zigzag spring silk of turning back back and forth in the face, there is runner to connect between front and back or left and right sides spring silk head and the tail, be with ring on the expansion link of telescopic lever and/or the fixed bar, its outer is connected and connects spring silk or runner limit.

The invention has the beneficial effects as follows: because this bar traveling box is made up of casing and telescopic barrel body; two parts have telescopic lever to connect; like this; the situation that does not need big volume; the telescopic barrel body is in the state of closing that closes; if in the time of will adorning as more thing; can elongate telescopic lever easily; it is elongated to allow the telescopic barrel body be stretched; the distance that it elongated is determined jointly by the longest distance that the perisporium length and the telescopic lever of telescopic barrel body is elongated; volume can be designed to our needed big volume very easily after can making the elongation of bar traveling box like this; the telescopic barrel body that has toroidal ring structure simultaneously; because ringed location makes the article that the telescopic barrel physical efficiency is fixing well and the better protect the inside is adorned, and special breakables can be placed in the cabinet space of hardware.
