Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to furniture that can be kept in an almost vertical position when not in use.

(Prior Art) Generally, when a bed device as furniture is installed indoors, it occupies a large amount of room even when not in use, which is extremely inconvenient.

Therefore, various bed devices are on the market that do not occupy a large amount of indoor space when not in use.
For example, one longitudinal end of the bed is rotatably connected to the lower ends of a pair of side plates of a box-shaped support with an open front, and when in use the bed is laid down almost horizontally, and when not in use it is turned almost vertically. There are known retractable bed devices in which the bed is erected vertically and housed in the support body, and stand-type bed devices in which the bed is rotatably attached to a stand and is supported in a substantially vertical position when not in use.

By the way, in such a bed device,
When not in use, the bed, which is erected almost vertically, must be prevented from inadvertently falling down.
Therefore, conventionally, as shown in Utility Application No. 62-23345 (unpublished), an engaging body is provided on the bed, while the engaging body is attached to the support body to which the bed is rotatably attached. An abutting body that comes into contact with the bed to restrict the upright position of the bed, and a stopper that engages with the engaging body to hold the bed in an upright state so that it cannot fall down are pivotally connected to the abutting body. Further, a release lever is rotatably provided on the support body, and by stepping on a petal provided at one end of the release lever and rotating it, the engagement between the engagement body and the stopper is released, It is possible to make Betsudo fall down. In other words, if the bed is in an upright position, it will not fall over unless you step on the pedal and turn the release lever.

Indeed, with this structure, the bed will not fall down unless you step on the petal.
However, since the petals are usually installed in places where anyone can easily step on them, for example, children may play a trick and accidentally knock down the bed.

(Problem to be solved by the invention) As described above, in the conventional bed device, when the bed rotatably supported by the support body is erected, the bed can be held in the erected state. However, the holding structure is easily released inadvertently.

This idea was developed based on the above circumstances, and its purpose was to prevent furniture such as beds held in an upright position from falling down simply by stepping on the petals, and to prevent the furniture from falling over simply by stepping on the pedal. An object of the present invention is to provide furniture that prevents accidental toppling over.

[Structure of the idea]

(Means and effects for solving the problem) In order to solve the above problem, this invention includes a support body, which is rotatably supported by the support body, and is laid down almost horizontally when in use, and when not in use. A furniture body that can be erected almost vertically; an engaging body that is provided on a lower end side of the furniture body when it is erected; and an engaging body that is slidably provided along the support body in the vertical direction a slide member formed with an engaging portion for engaging and holding the furniture main body in an upright state so as not to fall; a midway portion rotatably supported by the support body and one end connected to the slide member; one end of the lever is connected to the other end of the lever, and the other end is connected to a petal provided on the support body, and the engaging body is in engagement contact with the slide member, and the petal is connected to the other end of the lever. The elastic member is provided with an elastic member that expands due to contact resistance between the engaging body and the slide member when operated, and prevents the movement of the petal from being transmitted to the slide member via the lever. Unless the contact resistance between the slide member and the engaging body is removed, the engaging body cannot be removed from the engagement hole and the furniture body cannot be laid down.

(Example) An example of this invention will be described below with reference to the drawings. FIG. 1 shows a stand-type bed device as furniture, which bed device has a support 1. FIG. This support body 1 is formed from a rectangular frame 2 and a pair of end plates 3 erected at both ends of the frame 2 in the longitudinal direction. One widthwise end of a bed 4 serving as a furniture body is rotatably supported by these pair of end plates 3. The bed 4 is composed of an underframe 5 and a mattress 6 placed on the underframe 5. A bracket 6 is provided near one end in the width direction of both longitudinal end surfaces of the underframe 5.
(only one shown) is fixed, and this bracket 6
is pivotally attached to a support shaft 7 projecting from the end plate 3.

As shown in FIGS. 2 and 3, one end of a wire 8 is fixed on one end of the underframe 5 in the width direction closer to the end than the bracket 6.
This wire 8 is engaged with a first pulley 9 provided with its rotation axis horizontal and a second pulley 11 provided with its rotation axis vertical, and the other end is connected to a tension spring 12. There is. This tension spring 12 is arranged on the frame 2 with its axis horizontal,
The other end is engaged with an engagement piece 13 fixed to the frame 2. Therefore, when the bed 4 is lowered in the direction of the arrow from the upright state shown by the solid line in FIG. 1, the tension spring 1 is pulled through the wire 8. The restoring force of the tension spring 12 acts on the bed 4 so that the bed 4 can be rotated with a light force.

Note that the legs 1 are located on the other end of the lower surface of the underframe 5 in the width direction.
0 is rotatably provided, and if the legs 10 are erected when the bed 4 is laid down, the bed 4 is supported almost horizontally as shown by the chain line in FIG. It's becoming like that.

On the other hand, at one end in the width direction of the underframe 5 of the bed 4, as shown in FIG.
4 is fixed. The groove 14a formed in the engaging body 14 is configured to engage with and disengage from the inner peripheral edge of an engaging hole 16 of a slide member 15 provided in the frame 2 so as to be slidable in the vertical direction.
That is, this slide member 15 is
It is made of a plate material thinner than the width dimension of the groove 14a of No. 4. The slide member 15 is slidably inserted into a guide member 17 having a U-shaped planar shape and provided upright on the frame 2, and is opened by a pair of pins 18 installed between both sides of the guide member 17. It is prevented from coming off from the side. The slide member 15 is provided with the engagement hole 16, which is sufficiently long compared to the height of the engagement body 14, along the vertical direction at its upper end, and has an engagement pin in the middle. 19 is bored, and this engagement pin 19
protrudes from a long hole 21 bored in the guide member 17. Furthermore, a through hole 20 is bored in the guide member 17 at a position corresponding to the engagement hole 16 described above.

A support piece 22 is provided in the middle of one side of the guide member 17, as shown in FIG. A midway portion of a lever 23 is pivotally attached to this support piece 22. One end of this lever 23 engages with the engagement pin 19, and one end of a power transmission spring 24 as an elastic member is connected to the other end. The other end of this power transmission spring 24 is connected to a petal 25 provided on the frame 2. This petal 25 is pivotally attached at one end in the width direction to a mounting member 26 fixed to the frame 2 by a support shaft 27, and
A biasing spring 28 attached to this support shaft 27 biases the other end in an upward direction. Therefore, if the pedal 25 is stepped on against the biasing force of the biasing spring 28, the lever 23 will rotate in the direction shown by the arrow in FIG. 5 via the power transmission spring 24. The slide member 15 is adapted to be slid in the upward direction.

Since the center of gravity of the bed 4 in the thickness direction is located closer to the underframe 5 than the support shaft 7 that pivotally connects it to the support 1, the bed 4 in the upright state is more prone to collapse than in the vertical state. has been defeated by Therefore, one side of the groove 14a of the engaging body 14 is in contact with one side of the slide member 15, as shown in FIG. The strength of the power transmission spring 24 is determined by the strength of the engaging body 1.
4 and the slide member 15 so as to be extended with a force smaller than the contact resistance between the slide member 15 and the slide member 15. Therefore,
Even if the pedal 25 is stepped on while the engaging body 14 is in contact with the slide member 15, the power transmission spring 24 is only stretched by the pedal 25, and the lever 23 cannot be rotated to raise the slide member 15. Can not. In other words, the engaging body 14 and the slide member 15 cannot be disengaged from each other. Further, a positioning member 29 is provided protrudingly near the guide member 17. When the bed 4 is rotated until the lower surface of the underframe 5 comes into contact with the positioning member 29, the engaging body 14 and the slide member position 5 are brought into a non-contact state.

According to the bed device having such a structure, when the bed 4 is held in an upright state, the petal 2
5, the power transmission spring 24 only stretches and the slide member 15 does not slide in the upward direction, so the engagement body 14 does not come off from the engagement hole 16 of the slide member 15. In other words, even if a child or the like steps on the petal 25 as a mischief, the bed 4 will not fall over.

In order to lay down the bed equipment 4, the bed 4 which is in a slightly fallen state is placed so that the lower side surface 5a of the underframe 5 is placed on the frame 2 as shown in FIG.
It is rotated and raised in the direction shown by arrow A in FIG. 6 until it hits a positioning member 29 that stands above and parallel to the guide member 17. As a result, the engaging body 14 moves slightly in the direction indicated by arrow A in FIG. 6, so that the groove 14a of the engaging body 14 and the slide member 15 are out of contact. Next, when the pedal 25 is stepped on, the lever 23 is rotated via the power transmission spring 24, so that the lever 23 causes the slide member 15 to slide in the upward direction. When the slide member 15 rises, the engaging body 14
Since the slide member 15 is disengaged from the engagement hole 16 of the slide member 15, the bed 4 can be laid down in the direction opposite to the direction indicated by arrow A in FIG. In other words, according to this structure, in order to lower the bed 4,
In addition to simply stepping on the petal 25, the bed 4 must also be rotated to a substantially vertical position before it can be laid down. Therefore, even if the petal 25 is stepped on inadvertently, the bed 4 will not fall over.

In addition, when the bed 4 is raised from a collapsed state, the engaging body 14 provided on the bed 4 is
enters the engagement hole 16 of the slide member 15 as shown by the chain line in FIG.
The engaging body 14 can be automatically engaged with the engaging hole 16 without stepping on the pedal 25 to raise the engaging body 14.

In the above embodiment, when the pedal 25 is stepped on, the lever 23 is rotated via the power transmission spring 24 as an elastic member, but the elastic member may be a rubber instead of a spring. In short, it only needs to be something that stretches when a certain amount of force is applied and returns to its original state when that force is removed.

In addition, furniture is not limited to bed equipment,
For example, it may be any other piece of furniture such as a table, as long as it has a structure that allows it to be laid down when in use and erected when not in use.

[Effect of the invention]

As described above, in this invention, when a furniture body held in an upright position is to be laid down, the furniture body must be rotated to a certain extent and then the petal must be stepped on to cause the furniture body to fall down. Therefore, it is possible to eliminate the situation where, for example, a child steps on a petal as a mischief and accidentally causes the furniture body to fall over, as in the past.
