Bunk Bed Structure
Abstract
A bunk bed structure includes a plurality of supports and a
number of posts. Each support includes a wedged slot mounted
thereon for cooperation with the post and includes a screw hole
fixed below the wedged slot. The post is used to fix a plate
member. Each post includes a wedged tenon extending from an end
portion thereof and includes a positioning piece secured below the
wedged tenon and having an elongated bore. The post is inserted
relative to the wedged slot by using the wedged tenon to align the
elongated bore with the screw hole automatically. A screw is
inserted through the elongated bore and into the screw hole to fix
the post and the support together.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a bunk bed structure is
disposed between a plurality of supports and a number of posts by
using the wedged slots and the wedged tenons so that the support
and the post are aligned precisely and retained securely, and the
positioning piece of the post is provided to screw the screw with
the screw hole so that the wedged slot and the wedged tenon are
connected stably.
[0002] 2. Description of the Prior Art
[0003] A conventional bunk bed is design to include a top bed and a
bottom bed so as to facilitate usage in a limited space, especially
used in a family having at least two children.
[0004] A conventional bunk bed structure can be assembled by a user
and includes a support 5 and a post 6 to assemble the bunk bed
stably. The conventional support 5 includes a wedged slot 51 and
the post 6 includes a wedged tenon 61, but the bunk bed is
positioned by a bolt structure (as shown in FIG. 5), thus the
wedged slot 51 is in alignment with the wedged tenon 61 to assemble
the support 5 and the post 6 together, however an error occurs
during producing components, and the deeper the wedged tenon 61 is
inserted to the wedged slot 51, the more secure the wedged tenon 61
and the wedged slot 51 assemble, therefore a hole of the wedged
slot 51 and a bore of the wedged tenon 61 do not align with each
other to insert a bolt 7 exactly, and the post 6 has to be lifted
to facilitate an insertion of the bolt 7, but such as assembling
method (the support 5 and the post 6 are assembled together by
using the bolt 7) will deform or break the bolt 7, and after the
bolt 7 is deformed or broken, the post 6 disengages from the post 5
to disassemble the bunk bed, causing a danger.
[0005] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages.
SUMMARY OF THE INVENTION
[0006] The primary object of the present invention is to provide a
bunk bed structure that the support and the post are aligned
precisely and retained securely by ways of the wedged slot and the
wedged tenon, so as to be assembled quickly and easily.
[0007] Another object of the present invention is to provide a bunk
bed structure that the positioning piece of the post is provided to
screw the screw with the screw hole so that the wedged slot and the
wedged tenon are connected stably to prevent from disengagement as
being impacted.
[0008] To obtain the above objectives, a bunk bed structure
provided by a preferred embodiment of the present invention is
disposed between a plurality of supports and a number of posts,
wherein the support includes a wedged slot mounted thereon in
response to the post, and includes a screw hole fixed below the
wedged slot; the post is used to fix a plate member, includes a
wedged tenon extending from a lower end portion thereof, and
includes a positioning piece secured below the wedged tenon and
having an elongated bore; the post is inserted to the wedged slot
by using the wedged tenon to align the elongated bore with the
screw hole automatically, and a screw is inserted to the elongated
bore, and the screw hole is used to fix the post and the support
together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] The present invention will be clearer from the following
description when viewed together with the accompanying drawings,
which show, for purpose of illustrations only, the preferred
embodiment in accordance with the present invention.
[0015] Referring to FIG. 1, a bunk bed structure 10 in accordance
with a preferred embodiment of the present invention is disposed
between a plurality of supports 1 and a number of posts 2,
wherein
[0016] the support 1 includes a wedged slot 11 mounted thereon in
response to the post 2, and includes a screw hole 12 fixed below
the wedged slot 11;
[0017] the post 2 is used to fix a plate member 4, includes a
wedged tenon 21 extending from a lower end portion thereof, and
includes a positioning piece 22 secured below the wedged tenon 21
and having an elongated bore 221.
[0018] In assembly, the post 2 is inserted to the wedged slot 11 by
using the wedged tenon 21 to align the elongated bore 221 with the
screw hole 12 automatically, and then a screw 3 is inserted to the
elongated bore 221 and the screw hole 12 is used to fix the post 2
and the support 1 together (as shown in FIG. 2), thereby assembling
the post 2 and the support 1 securely.
[0019] Thereby, the support 1 and the post 2 are aligned precisely
and retained securely by ways of the wedged slot 11 and the wedged
tenon 21, so as to be assembled quickly and easily. Furthermore,
the positioning piece 22 of the post 2 is provided to screw the
screw 3 with the screw hole 12 (e.g., as illustrated in FIGS. 3 and
4, the positioning piece 22 includes the elongated bore 221 so that
when an depth error occurs during assembling the wedged tenon 21
and the wedged slot 11, the screw 3 can insert through the
elongated bore 221 to screw with the screw hole 12, hence the post
2 is supported completely by the support 1) so that the wedged slot
11 and the wedged tenon 21 are connected stably to prevent from
disengagement as being impacted.
[0020] While we have shown and described various embodiments in
accordance with the present invention, it is clear to those skilled
in the art that further embodiments may be made without departing
from the scope of the present invention.
