Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a bed device that allows a user to exercise on a pinerest.

(Prior Art) Recently, in order to increase the added value of bed devices, bed devices have been developed that allow users to exercise on a pinerest.

Conventionally, as a bed device for the purpose of
There is one shown in Japanese Patent No.-103130. In this prior art, a U-shaped rod is rotatably provided on the bed body, and by rotating this U-shaped rod against the restoring force of a spring, the user can increase the strength of his arms. It is designed to allow bending movements of the upper body.

(Problems to be solved by the invention) However, according to the bed device having such a structure,
The user can only exercise by rotating the U-shaped rod and tilting the upper body forward from a horizontal position, so even if the user has sufficient arm strength and abdominal muscle movement, he or she may not be able to exercise the back muscles. Furthermore, since the force required for the user to exercise is obtained from the reaction force of the spring, the spring is prone to premature wear and damage.

This invention was made based on the above circumstances, and its purpose is to make it possible to exercise not only arm strength and abdominal muscles but also back muscles, and to generate the necessary force for exercise without using springs. The object of the present invention is to provide a bed device that allows the user to obtain the following.

(Means and effects for solving the problem) This invention has the following features:
The bed comprises a bed body, a first frame part and a second frame part which are rotatably connected to each other at one end side, and is provided on the bed body in such a manner that these frame parts can be bent from the connecting part. a mat frame, a pinerest placed on the mat frame, and handles provided at substantially the center in the longitudinal direction of the bed body so as to be rotatable along the width direction and protruding from the top side of the pinerest at both ends. When the operating rod is rotated by the handle, the connecting portion between the first frame portion and the second frame portion of the mat frame is pushed up, and the mat frame is rotated. and a push-up mechanism for bending. The user then exercises by bending the mat frame against its own weight.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

The bed device shown in FIG. 1 includes a bed main body 1. The bed device shown in FIG.

This bed body 1 has a headboard 3 erected on one end side of a pair of parallel copper plates 2 spaced apart from each other and a footboard 4 erected on the other end side. A support crosspiece 5 is provided on the inner surface of the side plate 2 over the entire length in the longitudinal direction, and a mat frame 6 is provided on the crosspiece 5 as illustrated.

The mat frame 6 is made up of a first frame part 7 and a second frame part 8 in the shape of a trowel, which are pivotally connected at one end by a support shaft 9. In other words, the mat frame 6 has a structure that allows it to be bent from approximately the central portion in the longitudinal direction. The first frame part 7 located on the side of the headboard 3 has a first bracket 11 provided in the middle on both sides thereof, which is pivotally attached to one side of an engagement member 12 having an L-shaped cross section by a support shaft 13, and a foot Second frame part 8 located on the board 4 side
A second bracket 14 is provided in the middle of both sides thereof, and the other end of a link 15 whose one end is pivotally connected to this second bracket 14 is pivotally connected to a third bracket 16 fixed to the engagement member 12. are doing.

The mat frame 6 is installed on the bed body 1 by engaging the engaging member 12 with the support bar 5.

One end of an arm 17 having a trowel-shaped cross section in the middle is pivotally connected to a support shaft 9 to which the first frame part 7 and second frame part 8 of the mat frame 6 are pivotally connected. This arm 1
An elongated hole 18 is bored at the other end of the arm 17, and an elongated hole 18 is provided at one corner of a substantially triangular rotating plate 19, which together with the arm 17 constitutes a push-up mechanism. The first pin 21 is slidably engaged. Further, a second pin 22 is protruded from one of the remaining two corners of the rotating plate 19, and the other corner is fixed to the end of the operating rod 23. The second pin 22 is inserted into the recess 19a formed at the other end of the rotating plate 19 when the arm 17 is at an angle that almost overlaps the rotating plate 19 as shown in FIG. When engaged, the arm 17 is prevented from rotating further in the direction of the arrow. In this state, the mat frame 6 is held with its first frame portion 7 and second frame portion 8 substantially in a straight line.

As shown in FIG. 5, the operating rod 23 is made of a vibrator material, and collars 24 are fitted into both ends thereof. This collar 24 is rotatably supported by a bush 26 provided on an L-shaped support plate 25. The support plate 25 is provided with one side fixed to the approximately central portion in the longitudinal direction of the engaging member 12, and the bushing 26 is attached to the negative side.

One end side of an elbow 27 formed by bending a vibrator material into an L-shape is fitted into the collar 24, and is integrally connected to the operating rod 23 by a stopper pin 28. This elbow 2
The other end of the handle 7 protrudes toward the outer surface of the side plate 2 of the bed body 1, and one end of a handle 29 made of pipe material is connected thereto. The handle 29 is formed in an L-shape as shown in FIG. 2, and the other horizontal end thereof serves as a grip portion 31.

The connection structure between the handle 29 and the elbow 27 is shown in FIG. That is, at the lower end of the handle 29, a collar 3 is slidably fitted onto the elbow 27.
2 is fixed by a screw 33, and an elbow 27 similar to the collar 32 is located inwardly from this collar 32.
A cylindrical stopper member 34 that is slidably fitted on the outside is fitted and fixed by a stopper pin 35. The stopper member 34 has a pair of engagement grooves 36 opened on its lower end surface and spaced apart by 180 degrees in the circumferential direction. It is slidably engaged. The positioning pin 37 is located between the collar 32 and the stopper member 34.
A gap 38 is provided which is slightly larger than the diameter of.

Therefore, the handle 29 cannot be rotated because the positioning pin 37 is engaged with the engagement groove 36 of the stopper member 34, but it can be rotated by raising the handle 29 until these engagements are released. If the handle 29 is rotated 180 degrees and lowered in this state, the positioning pin 37 and the engagement groove 36 will engage again and the handle 29 will become unrotatable. In other words,
The handle 29 can be held non-rotatably in either a state in which the grip portion 31 is directed inward, as shown in solid lines in FIG. 2, or in a state in which it is directed outward, as shown in chain lines.

Note that, as shown in FIG. 5, the engaging member 12 is provided with an elastic material 38 such as rubber, and the mat frame 6 is joined to this elastic material 38. Further, a mattress 39 (shown in FIGS. 1 and 2) is placed on the mat frame 6.

When a user U exercises using a bed device having such a structure, the user U sits on the pinerest 39 with his or her feet facing the headboard 3 as shown in FIG. Headboard 3 as shown by the solid line in Figure 1.
Grasp the grip portion 31 of the handle 29 which is in a state where it has fallen to the side. From this state, when the handle 29 is rotated clockwise as shown by the arrow in FIG. It rotates as shown in Figures 3 and 4. Then, the first pin 21 protruding from the rotary plate 19 slides through the elongated hole 18 of the arm 17 and then pushes the arm 17 up. The arm 17 is a support shaft 13 that connects the first frame part 7 and the second frame part 8 of the mat frame 6.
Since the mat frame 6 is connected to the support shaft 13, the support shaft 13 of the mat frame 6 is pushed up. Then, the first frame portion 7 and the second frame portion 8 of the mat frame 6 are bent into a mountain shape as shown by solid lines in FIG. At this time, the link 15 connecting the second frame part 8 of the mat frame 6 to the engaging member 12 rotates in the direction shown by the arrow in FIG. Bending is done to Nissin. Therefore, by bending the mat frame 6 together with the mattress 39 in this way, the user U can bend his or her upper body backwards on the mattress 39 as shown by the chain line in FIG. You can train your armpits.

As shown by the solid line in FIG. 4, when the angle θ1 connecting the support shaft 13, the first pin 21, and the operating rod 23 is smaller than 180 degrees, when the user U loosens the force applied to the handle 29, Since the user U's own weight causes the arm 17 to rotate in the direction of lying down, the mat frame 6 is pushed down until it becomes horizontal. However, as shown by the chain line in FIG. 4, the two handles are rotated as shown by the chain line until the angle θ2 connecting the support shaft 13, the first pin 21, the actuator, and the rod 23 becomes greater than 180 degrees. Then, the end of the arm 17, which has a trowel-shaped cross section, engages with the corner of the rotating plate 19 from which the first pin 21 is protruded, and is tilted slightly counterclockwise rather than vertically. One side of the rotating plate 19 is joined to the other horizontal side of the support plate 25, and rotation in the clockwise direction is prevented. Therefore, the arm 17 will not fall down in either the left or right direction due to the weight of the user U acting on the mat frame 6, so the mat frame 6 will be bent into a mountain shape as shown in FIG. This allows the user U to exercise to stretch his or her back. To release this holding state, the handle 29 is forcibly rotated so that the angle formed by the support shaft 13, the first bottle 21, and the operating rod 23 is 180 degrees or less, and the mat frame 6 is leveled by its own weight. It will return to a normal state.

That is, according to the bed device having the above structure, the user U can bend the mat frame 6 on which the pinerest 39 is placed into a mountain shape by rotating the handle 29, so that the user U can straighten his or her upper body. Not only can you knock it forward,
It can be turned back later. Therefore, the user U can train his abdominal muscles and back muscles on the pine rest 39, and since he rotates the handle 29 against his own weight when bending the mat frame 6, he can also train his arm strength. . Furthermore, when the bed device is not used for exercise, if the grip portion 31 of the handle 29 is directed outward as shown in FIG.
9 does not get in the way of user U lying on top.

This invention is not limited to the above-mentioned embodiment; for example, the first and second frame parts of the mat frame, which are pivotally connected at one end side to the other, are not connected to the bed body at the other end and can be slid freely. Even if it is placed, it can be bent by rotating the handle. In addition, the handle is not rotatably provided on the elbow, but is detachably provided so that it can be removed when not in use and not get in the way when sleeping. Furthermore, although the push-up Imm is constructed of an arm and a rotating plate, it may be constructed using other structures such as a handle to rotate the disk eccentrically, and the mat frame is bent by the eccentric rotation of the disk.

(Effects of the Invention) As described above, the present invention allows the mat frame on which the pinerest is placed to be bent into a mountain shape against the weight of the user on the pinerest by operating the handle. . Therefore, users can not only lean their upper body forward on the pinerest, but also arch it backwards, allowing them to exercise not only their abdominal muscles but also their back muscles, while also rotating the handle against their own weight. ,
You can train your arm strength. Furthermore, since the user's own weight is used to obtain the kinetic force to rotate the handle, there is no possibility of early damage unlike in the case of conventional systems that use springs.
