Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed apparatus having a bed frame in which a board body is erected at a longitudinal end thereof.

[0002]

2. Description of the Related Art Generally, a bed apparatus has a bed frame on which a mattress is placed. This bed frame
Legs are vertically provided at four corners of the lower surface of the frame, and board bodies are provided upright at both ends in the longitudinal direction.

When a bed apparatus having such a structure is used, for example, for a hospital, and a doctor examines a supine patient on a mattress, small articles such as various instruments necessary for the examination and treatment are used. It is necessary to have an installation place near which the bed can be placed.

Conventionally, in order to secure such an installation place, a table has been installed near the bed apparatus. However, if a table is installed near the bed device, the above table can be used even when no medical examination is performed.
The bull occupies the space in the patient room, which can be very inconvenient, and can also be an obstacle when passing the bed equipment laterally, especially for patients with disabilities in hospitals. Since there is a risk of collision during walking, it is desired to secure a place for installing small items without placing a table or the like on the side of the bed apparatus.

[0005]

As described above, conventionally, for example, when the user is a sick person, a tape is used to secure an installation place for placing small articles such as a medical treatment tool when receiving medical examination. Since the use of the bull was done, the table occupies the indoor space, which sometimes became an obstacle when not using it.

The present invention has been made based on the above circumstances. The purpose of the invention is to make it possible to easily secure a place for placing small items and not to disturb the user when not in use. It is to provide a bed apparatus equipped with a bull plate.

[0007]

In order to solve the above problems, the present invention relates to a bed apparatus having a bed frame having a mattress placed on the upper surface thereof and a board body provided at the longitudinal end thereof. A link whose one end is pivotally attached to the outer surface side upper part of the board body, a table plate whose one end is pivotally attached to the other end of this link, and the outer surface side of the bed frame. A first stopper portion provided on the upper part,
A second stopper portion provided on an upper portion on the inner surface side of the board body, and a second stopper portion provided on the other end portion of one surface of the table plate, the table plate being on the outer surface side of the board body. , The table plate is held substantially perpendicular to the outer surface side of the board body by engaging with the first stopper portion, and the table plate is held at the upper end of the board body. It is characterized by including an engaging body which engages with the second stopper portion when it is rotated to the side and holds the table plate in a substantially horizontal state.

[0008]

According to the above construction, the table plate can be held on the board body in a substantially vertical state and a substantially horizontal state. By holding it in a substantially horizontal position when in use, it is possible to secure a place for installing small items, and when not in use, holding it in a substantially vertical position causes little obstruction.

The other parts can be undulated by a drive mechanism (not shown). Therefore,
A user (not shown) lying on the mattress 6 can maintain a posture of raising the upper half of the body by erecting a predetermined portion of the floor plate 5, for example, 5a.

A rectangular table plate 11 is provided on one of the board members, which is the foot board member 2b in this embodiment, as follows. That is, FIG. 1, FIG. 3A, and FIG.
Further, as shown in FIG. 4, a band-shaped mounting member 12 is provided upright in the widthwise central portion of the outer surface of the footboard body 2b along the vertical direction. A hollow first stopper member 13 having an inclined surface 13a of 45 degrees is fixed to the upper end of the mounting member 12, and one end of a pair of links 14 is rotatably supported by a first support shaft 15. It is supported.
A first engagement hole 13b is formed in the slope 13a of the first stopper member 13.

As shown in FIG. 4, the pair of links 14 are bent in a substantially doglegged shape, and both end portions of the strip-shaped plate are L-shaped between the other ends having a larger gap than the one ends. The bent bracket 15 is provided by connecting both ends thereof. That is, both ends of the bracket 15 are shown in FIG.
As shown in (a) and (b), an elongated hole 15a is formed, and both ends of the bracket 15 are respectively formed at the other ends of the pair of links 14 through the elongated hole 15a as shown in FIG. Is pivotally attached by a spindle 16.

An intermediate portion of the bracket 15 is the tape.
It is fixed to one end of the lower surface of the bull plate 11. This test
An engaging member 17 is provided on the other end of the lower surface of the bull plate 11. As shown in FIGS. 3 (a), 3 (b) and 4, this engaging body 17 has an L-shaped cross section, and has hollow mounting members 19 closed at both ends by side plates 18 having recesses 18a formed therein. . The mounting member 19 is provided with one side fixed to the lower surface of the table plate 11 so that the opened surface faces the bracket 15 side on one end side of the table plate 11.

A tubular member 21 is provided on the other side of the mounting member 19. A stopper shaft 22 is slidably provided on the cylindrical member 21 with its tip portion protruding from the other side of the mounting member 19 to the inside thereof. This stopper shaft 2
2 is biased in the protruding direction by a spring 23 provided in the cylindrical member 21, and a knob 24 is provided at the rear end.

As shown in FIG. 3 (a), when the table plate 11 is erected substantially vertically on the outer surface side of the footboard body 2b, the tip of the stopper shaft 22 becomes the first stopper. It slides along the slope 13a of the member 13.
As a result, the stopper shaft 22 is engaged with the engaging hole 13b formed in the slope 13a of the first stopper member 13 while rising against the biasing force of the spring 23. Therefore, in the state where the table plate 11 is erected almost vertically,
It is held on the outer surface side of the footboard body 2b. When the stopper shaft 22 is pulled against the urging force of the spring 23, the engagement state with the engagement hole 13b is released.

A second stopper member 31 is provided on the upper portion on the inner surface side of the footboard body 2b. This second
The stopper member 31 shown in FIGS. 3 (a), (b) and FIG.
As shown in FIG. 2, both ends are bent in an L shape, and a mounting plate 32 fixed to the inner surface of the hood board body 2b by a screw 33 is provided. Both sides of an engaging member 34 formed by bending a rod into a U-shape are fixed to the mounting plate 32.

As shown in FIG. 3 (a), when the table plate 11 is held in a substantially vertical state, it is rotated to a substantially vertical state as shown in FIG. 3 (b). Since the inclined end surface of the side 18 of the engaging body 17 provided at the other end of the lower surface slides along the engaging member 34, the side 1
The concave portion 18a of No. 8 engages with the engaging member 34. At this time, since the table plate 11 is connected to the link 14 through the long holes 15a formed at both ends of the bracket 15, it slides in the direction indicated by the arrow X in FIG. 3 (b). Therefore, the recess 18a of the engaging body 17 can be smoothly and reliably engaged with the engaging member 34.

Immediately before the recess 18a is engaged with the engaging member 34, the tip end of the stopper shaft 22 contacts the engaging member 34, so that the stopper shaft 22 resists the urging force of the spring 23 at that time. Then, when the concave portion 18a is engaged with the engaging member 34 and then released, the tip end portion of the stopper shaft 22 engages with the engaging member 34. Therefore, the table plate 11 is securely held in a substantially horizontal state without the other ends rising upward.

According to the bed apparatus having such a structure, the table plate 11 provided on the outer surface side of the footboard body 2b is
By holding the footboard body 2b substantially horizontally on the upper end side, small items can be placed on the upper surface thereof. Also,

When the table plate 11 is not used, the stopper shaft 22 is held by being engaged with the first stopper member 13, so that the table plate 11 is securely held without fluttering. Since the stopper shaft 22 sometimes engages with the second stopper member 31, the stopper shaft 22 is also securely held without floating upward.

Therefore, the table plate 11 is securely held in both the non-use state and the use state. Moreover, when the table plate 11 is released from the holding state when it is not used and when it is used, the stopper shaft 22 is pulled against the biasing force of the spring 23, and the first engaging member 13 or the second engaging member 13 is engaged. Since the engagement with the member 31 may be disengaged, the releasing operation can be performed easily and quickly.

In the above embodiment, the table plate is provided on the footboard side, but it may be provided on the headboard side or on both board sides, and the point is not limited at all. Not a thing.

[0023]

As described above, according to the present invention, the table plate is pivotally attached to the outer surface side of the board body provided at the longitudinal end of the bed frame, and the table plate is attached to the above-mentioned board plate. The outer surface of the board can be held in a substantially vertical state, and the upper end of the board can be held in a substantially horizontal state.

Therefore, if the table plate is held horizontally, it is convenient because the upper surface of the table plate can be used as a place for placing small articles, and when it is not used, it can be held in a substantially vertical state. Almost no hindrance.
