Description

  The present invention relates to a bunk bed, and more particularly to a bunk bed capable of realizing a bunk bed mode in which upper and lower bunks are stacked and a combined bed mode separated and combined.

  In Patent Document 1, in the bunk bed mode, the upper bed has a sufficient height, the side fence of the upper bed is set sufficiently high to clear the safety standards, and the side fence of the lower bed is set sufficiently low. There is provided a reconfigurable bunk bed that facilitates getting on and off, and the appearance of the two beds is exactly the same in the bunk bed mode.

  Specifically, it is a reconfigurable bunk bed that can be recombined into a bunk bed mode and a bunk bed mode consisting of 2 single bunk beds that have the same external appearance, and have high support legs on both sides. And a pair of first leg frames provided with leg-side connecting means at a predetermined height from the lower end of the inner side surface of the support leg, and provided with a connecting portion at the upper end of the support leg, and having a low height on both sides. The supporting leg has a leg-side connecting means having the same height and the same structure as the supporting leg of the first leg frame body on the inner side surface of the supporting leg, and the first leg frame body at the lower end of the supporting leg. A pair of second leg frames provided with connecting portions that are connected to each other at the lower end of the supporting leg, and a long member having a narrow vertical width, and the first leg frame and the second leg at both ends. The first connecting means that is detachably connected using the leg-side connecting means of the frame body, and the receiving portion projects along the inner surface A pair of first side frame bodies and a long member whose vertical width is wider than that of the first side frame body, and using the leg side connecting means of the first leg frame body and the second leg frame body at both ends. A second connecting means for detachably connecting is provided, and a receiving portion that projects from the lower end along the lower portion of the inner side surface is the same as the receiving portion of the first side frame, and the upper portion is a side fence portion. A reconfigurable bunk bed comprising: a pair of second side frames made; and two sets of floor members that can be supported on receiving portions of the first side frame and the second side frame. Is disclosed.

  When the bunk beds described in Patent Document 1 are separated and used as an independent bed, they can be made into two beds having the same appearance, arranged, separated, or appropriately arranged. However, the indoor space cannot be denied. Usually, when a bunk bed is used, it is often used by siblings or sisters having different physiques. However, an independent bed is too large for a child with a small physique, and the indoor space is wasted.

In addition, although it is a ladder for installing and using on the structure which has a gradient surface in patent document 2, the whole ladder connects the several division body of an upper element, an intermediate | middle part element, and a lower element so that attachment or detachment is possible. The point comprised by this is disclosed. In addition, there are many common stepladders that can be bent and used in an inverted V shape at the center and can be used as a ladder by extending straight.

H2 is set high, and a part of the leg side of the first bed 1 is positioned below the floor member 9 of the second bed 2 so as to be crossable. In this case, since the lower surface of the floor member 9 is usually higher than the lower end of the side frame 8, the height H1 of the support leg 10 of the first bed 1 is the second lower than the lower end of the support leg 14 of the second bed 2. When the height H3 up to the lower end of the two-bed side frame 8 is higher, the second bed 2 is lifted slightly and a part of the first bed 1 is pushed below the floor member 9. Become. If one leg frame body 4 of the first bed 1 passes below the side frame body 8 of the second bed 2, the second bed 2 may be lowered to the floor surface.

  However, from the viewpoint of workability, the height from the lower end of the support leg 14 of the second bed 2 to the lower end of the side frame 8 of the second bed 2 from the total height H1 of the support leg 10 of the first bed 1. It is preferable to set H3 high. In this case, it is possible to push one leg frame body 4 of the first bed 1 through the lower side of the side frame body 8 of the second bed 2. In this embodiment, the height is set under this condition.

  The ladder 3 has a hook 18 that can be locked to the side frame 8 of the second bed 2 in the form of a bunk bed at the upper end, and can be divided into an upper ladder 19 and a lower ladder 20, and an upper ladder. The dividing line of 19 and the lower ladder 20 is made to correspond to the horizontal plane including the lower end of the leg frame 7 of the second bed 2. The upper ladder 19 and the lower ladder 20 have a normal structure in which tread plates 22,... Are horizontally disposed between the support plates 21 and 21 on both sides at regular intervals, and the support plates of the upper ladder 19 and the lower ladder 20, respectively. 21 and 21 are abutted in a straight line, and the joint plates 23 and 23 are aligned and screwed to the inner surface.

  In the present invention, when the first bed 1 and the second bed 2 are separated and installed on the floor surface, and the bunk bed form is used independently, a part of the leg side of the first bed 1 is the first. A composite bed mode in which the first bed 1 and the second bed 2 are oriented in the direction perpendicular to each other and partially overlapped as shown in FIGS. 4 to 6 is positioned below the floor member 9 of the two beds 2. It can be realized. In this case, the hook 18 of the separated upper ladder 19 is locked to the side frame 8 of the second bed installed on the floor surface, and the lower end of the inclined upper ladder 19 is used in contact with the floor surface. It was possible.

  In the illustrated embodiment, approximately half of the first bed 1 is arranged near the left leg frame 7 below the floor member 9 of the second bed 2, and an upper ladder 19 is installed in the vacant space on the right side. ing. In addition, what is necessary is just to adjust the length of the overlap part of the 1st bed 1 with respect to the 2nd bed 2 according to the physique of the child who uses the 1st bed 1 suitably.

  Further, the side frame 8 of the second bed 2 is provided with a side fence portion 25 on the upper part of the connecting base material 24 and widened vertically so that it can be safely used in a bunk bed mode, a bunk bed mode, or a composite bed mode. Increases sex. On the other hand, the side frame 5 of the first bed 1 has a shape in which reinforcing portions 26 are provided only at both ends of the upper portion of the connection base 24, and the vertical dimension that abuts on the support leg 10 is increased. The same connection stability as that of the side frame 8 of the second bed 2 is ensured. Since the side frame 5 of the first bed is composed only of the connecting base material 24 in the intermediate portion where the reinforcing portion 26 does not exist, the height is low and even a small child can easily get on and off the first bed. Not only can the first bed be used as a sofa.

  Although not shown, the upper and lower support legs 10 and 14 are connected to each other by fitting a pin to both joint surfaces and screwing the connecting metal fitting along the side surface. For connecting the side frames 5 and 8 to the support legs 10 and 14, a vertical slit groove is formed in the support legs 10 and 14, and a locking pin is provided horizontally in the slit groove, A hook member that is inserted into the slit groove and is dropped into the locking pin and locked to the end of the connecting base member 24 of the side frames 5 and 8 is projected from the outside of the support legs 10 and 14. The structure which screwed the bolt to the said reinforcement part 26 or the side fence part 25 was employ | adopted.

  FIGS. 7 to 10 show other embodiments of the ladder 3 in which the rear surfaces of the divided portions of the upper ladder 19 and the lower ladder 20 are connected to each other by a hinge 27 so that the upper ladder 19 and the lower ladder 20 can be bent 180 degrees. The dividing line was made to coincide with the horizontal plane including the lower end of the leg frame 7 of the second bed 2 so that the lower ladder 20 could be folded along the back side of the upper ladder 19. The support plates 21 and 21 of the upper ladder 19 and the lower ladder 20 can be maintained in a linear state or in a parallel folded state by appropriate holding means (not shown). 7 and 8, the upper ladder 19 and the lower ladder 20 are in a straight line state, and the hook 18 at the upper end is locked to the connecting base material 24 of the side frame 8 of the second bed 2. The lower end of the inclined ladder 3 is brought into contact with the floor surface. In the composite bed mode shown in FIGS. 9 and 10, the lower ladder 20 is folded behind the upper ladder 19 and the upper end of the upper ladder 19 is folded. The hook 18 is locked to the connecting base material 24 of the side frame 8 of the second bed 2 and the lower and upper ladders 19 and 20 in an inclined state are brought into contact with the floor surface so that they can be used.

  Here, since the vertical height of the lower ladder 20 in the inclined state coincides with the height H1 of the support leg 10 of the first bed 1, the second height is higher than the total height H1 of the support leg 10 of the first bed 1. By setting the height H3 from the lower end of the support leg 14 of the bed 2 to the lower end of the side frame 8 of the second bed 2 high, the lower ladder 20 is moved to the second bed 2 as shown in FIGS. The side frame body 8 is inserted and stored below.
