Abstract

PURPOSE: Provided is a suitcase with a stepwise caterpillar attached which lets the caterpillar projected to minimize friction between the suitcase and steps so that it increases convenience in carrying the suitcase. CONSTITUTION: The suitcase with the stepwise caterpillar attached is characterized by comprising the parts of: an elastic connection string which connects a suitcase body and a variable grip(2); the caterpillar(4) which is projected by transforming the variable grip; a housing groove(5) which stores the caterpillar; a rotation wheel(6) which is moved in a single direction to prevent backward skidding; and an E-typed fixing pin which fixes the rotation wheel.

Description

Traveling suitcase with caterpillar {Traveling suitcase with caterpillar equipment}

The present invention is a storage groove for storing the caterpillar (4), the caterpillar (4) protruding by the deformation of the variable handle (2) of the elastic body connecting the bag body (1) and the variable handle (2) (5), using a unidirectional rotary wheel (6) to prevent slipping in the rear when moving the stairs and E-type fixing pin (7) for fixing it by using a travel bag that can be kept slip-free and clean storage on the stairs .

In the present invention, the length of the variable handle (2) is increased at the time of moving the stairs and the caterpillar (4) stored in the storage groove (5) protrudes, the angle by the handle joint (2a) in accordance with the user's height and inclination of the stairs When is changed, if the staircase is steep inclines the connecting straps (3) of the elastic body is configured in the form to make a proper inclination angle.

Various types of travel bags have been presented so far, but there was no form of carrying the handle and the easy-to-carry function using the caterpillar.

E-type fixing pins to secure the wheels with variable handles (2), caterpillars (4), unidirectional rotating wheels (6) to prevent rear slipping, and to make the proper inclination angle to facilitate the transport of the suitcase. It is configured to maintain the proper inclination angle in combination with (7), and to keep the bag clean by the storage groove (5) built in the main body (1).

4 is a side projection of the variable handle (2) of the present invention

(1) Adjustable Handle (2)

The variable handle (2) is a structure by the joint of the handle and the connecting strap (3) of the elastic body, the inside is composed of a handle joint (2a), a handle fixing pin (2b), a handle guard rail (2c). When the length of the handle is shortened, the handle is fixed with a fixing pin (2b), and when the caterpillar is used with a long length, the caterpillar (4) protrudes by releasing the fixing pin and removing the handle from the handle guard rail (2c). If the stair slope is more severe, the elastic straps are stretched and driven to slide properly.

(2) Caterpillar (4)

Caterpillar (4) is a structure that is operated by the combination of the unidirectional rotary wheel (6), E-type fixed pin (7), the caterpillar (4), unidirectional rotary wheel (6), E-type fixed pin for fixing it, It is composed of a caterpillar groove 4a built in the center of the caterpillar 4 to prevent idleness of the wheel and the caterpillar. The rear sliding is prevented by the unidirectional rotating wheel 6, and the wheel 6 and the caterpillar groove 4a are used so that there is no idling.

(3) Storage groove (5)

The accommodating groove 5 is a structure in which the variable handle 2 and the caterpillar are operated at the same time, and includes the accommodating groove 5, the caterpillar 4, and the caterpillar stop ring 5a. At the same time the handle (2) is pulled out and the force is transmitted to the caterpillar stop ring (5a) so that the caterpillar (4) can be pulled out. To enter).

(1) convenient carrying

Appropriate angle of inclination is maintained by the use of the variable handle (2), and the slip prevention effect by the unidirectional rotating wheel (6) and the caterpillar groove (4a) makes it easy to carry the bag in a place where wheels, such as stairs, cannot be operated by anyone. Become.

(2) clean storage

In the usual case is stored by the caterpillar receiving groove (5) built in the main body (1), because the water can be cleaned in the protruding state can be kept clean, unlike the existing wheel bag where dirt on the wheel when moving.

(3) wide application

Caterpillar and handle can be easily combined in general bags, so it is easy to apply to all transportation devices such as luggage as well as travel bags.

Claims (2)

Carrying structure for facilitating the step transport by the combination of the handle (2), the unidirectional rotating wheel (6) to prevent the rear slip, the caterpillar groove (4a) can be changed in length and angle according to the inclination angle of the stairs. The storage structure of the caterpillar (4) and the caterpillar storage groove (5) can interlock with the handle (5) if necessary to protrude if necessary and keep clean.
