DETAILED DESCRIPTION

[0048] Hereinafter, desired embodiments of a side door for a forklift of the present invention will be described with reference to accompanying drawings.

[0049] As illustrated in FIGS. 3 to 6, a side door for a forklift according to an embodiment, the side door provided at a side portion of a vehicle body of the forklift, includes a door panel 50 at of which one side a door securing pin 58 is slidably provided; a hinge securing bracket 51 secured to the vehicle body; a first hinge block 52 coupled to the hinge securing bracket 51 to be relatively rotatable by disposing a first hinge shaft 53 between the first hinge block 52 and the hinge securing bracket 51; a second hinge block 54 coupled to the first hinge block 52 to be relatively rotatable by disposing a second hinge shaft 54 between the second hinge block 54 and the first hinge block 52, the second hinge block 54 secured to the door panel 50; and a locking member 56 for locking and securing the second hinge block 54 to the first hinge block 52 so that the second hinge block 54 is rotatable integrally with the first hinge block 52. In such an embodiment, it is desirable that the first hinge block 52 is rotatable 90 degrees with respect to the hinge securing bracket 51, and the second hinge block 54 is rotatable 90 degrees with respect to the first hinge block 52.

[0050] The first hinge shaft 53 passes vertically through the first hinge block 52, and is fitted to the hinge securing bracket 51 in an insertion manner from the outside of the first hinge block 52. In addition, the second hinge shaft 55 is provided so that it passes vertically through a protruding portion 52 of the first hinge block 52, and also passes through protruding portions 54 of the second hinge block 54, each located at an upper portion and a lower portion of the protruding portion 52 of the first hinge block 52. In addition, the locking member 56 includes a hinge securing pin 56a that is provided to pass through the second hinge block 54, and secures the second hinge block 54 to the first hinge block 52 by allowing an inner end portion of the hinge securing pin 56a to be inserted to a hole defined at the first hinge block 52; a safety ring 56b that is provided at an outer end portion of the hinge securing pin 56a which protrudes outwardly of the second hinge block 54; and a return spring 56c that is provided outside the hinge securing pin 56a to allow the inner end portion of the hinge securing pin 56a to be inserted into the hole of the first hinge block 52.

[0051] As illustrated in FIGS. 5 and 6, the door panel 50 may be formed, divided into a lower panel 50a at which the second hinge block 54 is provided and an upper panel 50b which is connected to an upper portion of the lower panel 50a without a hinge portion.

[0052] The side door for a forklift according to an embodiment having the above-described structure is open 90 degrees or 180 degrees, as necessary, so that a necessary operation can be performed.

[0053] When the door panel 50 is opened for maintenance of parts inside the side door, the door panel 50 is open only up to 90 degrees.

[0054] That is, after the door securing pin 58 provided at one side of the door panel 50 is separated from the vehicle body, the door panel 50 is rotated.

[0055] In such a case, since the second hinge block 54 secured to the door panel 50 is secured to the first hinge block 52 by the hinge securing pin 56a of the locking member 56, the door panel 50 is open only up to 90 degrees.

[0056] That is, due to the first hinge block 52, which is rotatable only up to 90 degrees with respect to the hinge securing bracket 51 secured to the vehicle body, the door panel 50 may be open only up to 90 degrees.

[0057] Accordingly, the door panel 50 may be open only up to 90 degrees in a rotated state, as illustrated in FIG. 5, and in such a state, general operations such as maintenance of parts are performed.

[0058] On the other hand, when it is necessary to completely open the side door as in the case of battery replacement, in a state that the door panel 50 is rotated 90 degrees through the same process as described above, securing of the first hinge block 52 and the second hinge block 54 by the locking member 56 is released.

[0059] Thereafter, when the door panel 50 is further rotated 90 degrees, the door panel 50 is completely open 180 degrees.

[0060] In a case where the hinge securing pin 56a is pulled by using the safety ring 56b of the locking member 56, the inner end portion of the hinge securing pin 56a is separated from the hole of the first hinge block 52, thus releasing securing, and the second hinge block 54 may be rotated with respect to the first hinge block 52.

[0061] Since the second hinge block 54 may be further rotated 90 degrees with respect to the first hinge block 52 that has been rotated only by 90 degrees with respect to the hinge securing bracket 51, the door panel 50 may be open up to 180 degrees in a rotated state with respect to the vehicle body.

[0062] Accordingly, the battery or the like may be replaced without interference of the door panel 50.

[0063] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, although specific terms have been employed, they have been used in a generic sense only to facilitate the description of the subject matter of the specification and to aid the understanding of the invention, and it is not intended to limit the scope of the specification. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.

INDUSTRIAL APPLICABILITY

[0064] According to an embodiment, a door is provided at a side portion of a vehicle body of a forklift, and an operator may select, as necessary, the door to be open 90 degrees or 180 degrees, parallel to one surface of the vehicle body, with respect to the vehicle body such that a battery provided at a side portion of the vehicle body of the forklift can be quickly and conveniently replaced.
