The present invention relates to a ladder used to install in the cabin bed of the sleeper, and more particularly to a folding ladder for the cabin of a sleeper car to effectively utilize a narrow space by building a folding ladder using a hinge.

The conventional ladder 31 installed on the bed of the bed car currently operating and using the bunk bed is located on the longitudinal frame 33 and the transverse frame 34 of the bed 32 as shown in FIG. As it was a type that was to be used in a completely fixed condition, the ladder was occupying a certain area of installation space, and it was emerging as a major factor to narrow the relatively narrow interior space, thereby causing a lot of inconvenience for passengers. There is a situation.

The present invention was devised to solve this problem, and it was designed to solve this problem. By constructing a folding ladder using a hinge to be installed on the bed frame of the bed, the ladder should be folded on the bed side of the bed when not in use. Its purpose is to make it possible to simply unfold and use the narrow space in the car effectively. The composition will be described in detail based on the accompanying drawings.

As shown in Figures 2 to 5, having a proper length A plurality of hinges 2 are fixedly installed at appropriate intervals inside the longitudinal section 1 of the form, and each connector 4, 4 'is provided at both ends of the multiple transverse sections 3 and 3a having the same shape as the longitudinal section 1. ) And at the same time the hinge (2) inside the longitudinal section (1) and the end (3, 3a) one end of the connector (4) is assembled as a hinge pin (5), the hinge pin (5) is a screw (6) As a result, it is firmly fixed on the hinge 2 so that a plurality of transverses 3 and 3a can be assembled and installed in a state in which they can flow on the longitudinal section 1, and at one end of the longitudinal section 1, a lock piece 7a is provided at the end. ) Is installed in a state in which it is bent as a pin (8), and the buffer rubbers (9, 9 ') are fixed to the lower and inner side proper portions. (10) is fixed to the lock upper portion of the handle 10 in the upper portion of the lock piece (11a) is formed integrally with the end of the lock operation interval 11 of the appropriate form Assemble and install as a pin 12 in a flowable state, but between the handle 10 and the lock operation 11 is installed between the stop springs 13 so that the lock operation 11 is always touched and at the same time the lock piece ( 11a) is assembled and installed in the state of being positioned inside the longitudinal section 1, and the buffer rubber 16 is fixed to the upper end of the longitudinal section 1 through the fixing plate 14 and the screw 15, but the buffer rubber 16 The end of the) is fixed to the state protruding by the appropriate length on the longitudinal section (1) to form a ladder 20, while fixing the plurality of hinges 17 on the longitudinal frame 33 of the bed 32 at appropriate intervals To assemble and install one end of the connector 4 'between the transverses 3 and 3a as the hinge pins 18. The hinge pins 18 are fixedly installed on the hinges 17 as screws 6 so that one end is securely installed. The transverse span (2), which is installed and connected to (1), is connected to and installed in the movable state on the vertical frame (33). The ladder 20 is assembled and installed in a state that can be folded or unfolded while being rotated up and down about the hinge 17 on the longitudinal frame 33, and the pin 21 is placed on the inner side of the transverse 3a positioned at the top. Lock member (24) having locking groove (23) having a locking groove (23) as a screw (22) and the lock piece (11a) of the lock operation section (11) assembled to the handle (10) coincide with the locking groove (23). While being inserted into or coupled to the lock member 24, the ladder 20 can be supported and fixed in a folded state, and the ladder 20 assembled in a movable state on the hinge 17 of the longitudinal frame 33 is provided. On the transverse frame 34 of the bed 32 positioned at the rotation radius of the interlocking fixture 7 in the unfolded state, the fixing piece 25 is configured to engage or separate the lock piece 7a of the interlocking fixture 7. It is configured to firmly support and secure the ladder 20 in the unfolded state by being fixedly installed. Reference numeral 26 shows a bush.

Looking at the state of use and the effect of the present invention made of such a configuration as follows.

Ladder 20 of the present invention is a cross-section in a state in which a plurality of transverse (3, 3a) is assembled and installed in a rotatable state through the hinge (2) and the connector (4) in one longitudinal (1) having a proper length (3, 3a) bar is connected to the hinge (17) fixed on the longitudinal frame 33 of the bed 32, the end of the connector (4 ') is installed in a state that can be folded by folding, ladder In the state in which 20 is attached, the transverses 3 and 3a, which are connected to the respective hinges 2 and 17, are horizontal and the lower end of the longitudinal section 1 is in contact with the bottom plate 35 of the vehicle body. In this state, the lock piece 7a at the end is fixed on the transverse frame 34 of the bed 32 while rotating the interlocking fixture 7 mounted as the pin 8 on the upper end of the interlock 1 in this state. It is convenient to use after fixing and firmly supporting the ladder 20 in the unfolded state by walking on the fixing piece 25. Rubber buffer 9 is to exert a cushion function.

If you want to fold after using the ladder 20 of the present invention unfolded in such a state, the interlocking fixture 7 in the locked state is separated on the fixing piece 25 and then simply folded by pressurizing with an appropriate force while rotating upward. In this case, the transverse (3, 3a) is installed between the hinges (2, 17) to be fitted into the interior of the longitudinal section (1), while the hinge pin (18) of the vertical frame (33) is established as a starting point At the same time, the lock piece 11a formed integrally with the lock operation section 11 on the handle 10 is fitted into the locking groove 23 of the lock member 24 installed on the inner side of the transverse 3a at the uppermost end. It is to maintain the folded state, wherein the buffer rubber 16 protruding in the upper section (1) when the ladder 20 is folded to first contact the vertical frame 33 to exert sound insulation and dustproof function And the buffer rubber 9 'inside the longitudinal section 1 is also transverse ( 3, 3a) to alleviate the noise and impact of contact.

When unfolding the ladder 20 in the folded state as described above, it is easy to grasp and pull the lock operation interval 11, which is built up inside the handle 10 as the pin 12, simultaneously with the handle 10. As the ladder 20 is separated by the lock piece 11a fitted on the locking groove 23 while the lock operation 11 is pivoted down about the pin 12, the process is performed. It will be unfolded downward.

As described above, the folding ladder of the present invention completely solves all the problems caused by installing and using a conventional ladder. It is a practical and profitable design that can be folded and stored on the frame side so that the narrow space inside the car can be utilized very effectively.
