Description

The present invention relates to elevating fixtures.

In the office space, desks are generally arranged to provide a work area for the office worker. In such a desk, the height of the top plate, which makes it easy to work, varies greatly depending on the physique, gender, taste, work content, etc. of the worker. Therefore, there is known a top plate elevating type fixture in which the height of the top plate can be changed up and down (see Patent Document 1 below).

By the way, in recent years, business using electronic devices such as smartphones and tablet computers has become widespread. When the user places the electronic device on the top plate of the furniture and uses it, it is easier to see if the electronic device is tilted backward. For example, a support base has been proposed in which an inclined surface inclined backward is provided on a mounting surface of a table and an electronic device can be supported along the inclined surface (see Patent Document 2 below).

When the user's line of sight is high with respect to the electronic device, it is easier to see if the angle of the inclined surface is gentle, and when the height of the user's line of sight is low, it is easier to see if the angle of the inclined surface is steep. It is preferable that the angle of the display of the electronic device can be changed according to the posture and preference of the user. In particular, when an electronic device is placed on the top plate in a top plate elevating fixture, the visibility of the electronic device may decrease due to a change in the height of the top plate.

Therefore, there has been proposed a support device in which a slide member is provided in an input device of an electronic device, a support portion is provided in a display, and the slide member and the support portion are connected by a hinge. The angle of the display can be changed by changing the angle between the slide member and the support portion with the hinge (see Patent Document 3 below).

Japanese Unexamined Patent Publication No. 2016-87025 Utility Model Registration No. 3187419 JP-A-2015-22767

However, in Patent Document 3 described above, a support device such as a slide member, a hinge, and a support portion must be fixed to an input device or a display, and the support device is unnecessary when simply carrying and using an electronic device. There is a problem that it looks bad. For this reason, it is desired that the elevating fixture itself can change the inclination of an object such as an electronic device.

The present invention has been made in view of the above circumstances, and provides an elevating fixture that can support the object by changing the inclination of the object according to the height of the object.

The present invention employs the following means in order to solve the above problems.
That is, the elevating fixture according to the present invention includes a lower structure installed on the floor surface and an upper structure supported by the lower structure so as to be able to move up and down, and the upper structure is an object. At a support position higher than the support position for supporting the object by the lower support member and the lower support member, the upper support member for supporting the object, and the lower structure are supported on the upper surface. It has a top plate having a mounting surface, and at least one of the lower support member and the upper support member is movable in a direction facing the upper structure by a user, and the lower support member is supported. The member is placed on the previously described surface of the top plate and can move in the opposite direction on the top plate, and the upper support member has a shelf plate provided above the top plate. The object is characterized in that it is supported by the end of the shelf board to which the user faces .
Further, the elevating fixture according to the present invention includes a lower structure installed on the floor surface and an upper structure supported by the lower structure so as to be able to move up and down, and the upper structure is an object. It has a lower support member for supporting the object and an upper support member for supporting the object at a support position higher than the support position for supporting the object by the lower support member. At least one of the upper support members is movable in a direction opposite to the upper structure, and the lower support member has an article accommodating portion capable of accommodating an article and a lower portion of the object. It has a lower support portion for supporting, and the lower support portion is a groove portion formed so as to be recessed downward in the upper end portion of the lower support member.

In the elevating fixture configured in this way, the heights of the lower support member and the upper support member change depending on the lower structure installed on the floor surface. As a result, when the height of the lower support member and the object supported by the upper support member changes, at least one of the lower support member and the upper support member is opposed by the user to face the upper structure. By moving in the direction, the inclination of the backward tilt of the lower support member and the object supported by the upper support member can be changed. Therefore, the object can be supported while changing the inclination of the backward inclination of the object according to the height of the object.
In addition, the object is supported at the end of the shelf plate provided above the top plate facing the user. Therefore, the configuration of the upper support member that supports the object can be simplified.

Further, in the elevating fixture according to the present invention, the upper structure is supported by the lower structure and has a top plate having a mounting surface on the upper surface, and the lower support member is described in front of the top plate. It is preferable that the product is placed on a mounting surface and can move on the top plate in the facing direction.

In the elevating fixture configured as described above, the lower support member is placed on the mounting surface of the top plate supported by the lower structure, and can move on the top plate in the opposite direction. Therefore, by moving the lower support member in a direction closer to the user, the object is in a posture of being greatly tilted backward, and by moving the lower support member in a direction away from the user, the object is moved along the vertical direction. It becomes a vertical posture or a small backward leaning posture from the vertical direction. Therefore, since the inclination of the backward tilt of the object changes only by moving the lower support member on the top plate, the structure of the lower support member that can move in the opposite direction can be simplified.

Further, in the elevating fixture according to the present invention, the superstructure extends upward from the top plate, is arranged along the facing direction, is orthogonal to the facing direction, and is along the previously described surface of the top plate. The lower support member may have a pair of movement restricting portions arranged apart from each other in the orthogonal direction, and the lower support member may be arranged between the pair of movement restricting portions while the movement in the orthogonal direction is restricted.

In the elevating fixtures configured in this way, the superstructure extends upward from the top plate and is arranged along the facing direction, and is arranged orthogonal to the facing direction and separated in the orthogonal direction along the mounting surface of the top plate. It has a pair of movement control units. The lower support member is arranged between the pair of movement restricting portions while the movement in the orthogonal direction is restricted. Therefore, when the lower support member is moved in the opposite direction, the displacement in the orthogonal direction is suppressed, and the inclination of the backward tilt of the object can be easily adjusted.

Further, in the elevating fixture according to the present invention, the lower support member may have an article accommodating portion capable of accommodating an article and a lower support portion supporting the lower portion of the object.

In the elevating fixture configured as described above, the lower support member has an article accommodating portion capable of accommodating the article and a lower support portion supporting the lower portion of the object. Therefore, since the lower support member itself can accommodate the article and can support the lower portion of the object, it is not necessary to separately provide the article accommodating portion, which is highly convenient.

According to the elevating fixture according to the present invention, the inclination of the object can be changed according to the height of the object and can be supported.

When each leg member 12 receives a command signal, a drive motor is driven in response to the command signal to move the intermediate support 12b and the upper support 12c up and down, and the height of the top plate 30 is adjusted. ..

In the top plate elevating desk 100 configured in this way, the height of the top plate 31 changes due to the legs 1 installed on the floor surface F, and the tray 70 placed on the top plate 31 accordingly. And the height of the shelf plate 60 provided above the top plate 31 changes. As a result, the height of the electronic device E supported by the front end portion 60f of the tray 70 and the shelf board 60 changes. When the user pulls out the tray 70 forward, the electronic device E is in a posture of being greatly tilted backward, and when the tray 70 is pushed backward, the electronic device E is in a posture of being vertically tilted or slightly tilted backward from the vertical direction. Therefore, the electronic device E can be supported while changing the inclination of the electronic device E according to the height of the electronic device E that changes with the change in the height of the top plate 31.

Further, the tray 70 is placed on the mounting surface of the top plate 31 supported by the leg body 1 and can move in the front-rear direction on the top plate 31. Therefore, by moving the tray 70 in the direction closer to the user (forward), the electronic device E is in a greatly tilted posture, and by moving the tray 70 in the direction away from the user (rear), the electronic device E is in a greatly tilted posture. E becomes a posture along the vertical direction or a posture slightly tilted backward from the vertical direction. Therefore, since the inclination of the electronic device E changes only by moving the tray 70 on the top plate 31, the lower support member can have a simple structure.

Further, the tray 70 has an article accommodating space S1 capable of accommodating articles and a groove portion 76 for supporting the lower portion of the electronic device E. Therefore, since the tray 70 itself can store the articles and can support the lower part of the electronic device E, it is not necessary to separately provide the article accommodating portion, which is highly convenient.

Further, a side plate panel 50 and a partition panel 56 which extend upward from the top plate 31 and are arranged along the front-rear direction and are arranged apart from each other in the left-right direction are provided. Since the tray 70 is arranged between the side plate panel 50 and the partition panel 56 material along the side plate panel 50 and the partition panel 56, the tray 70 is restricted from moving in the left-right direction. Therefore, when the tray 70 is moved in the front-rear direction, the positional deviation in the left-right direction is suppressed, and the inclination of the electronic device E can be easily adjusted.

Further, the electronic device E is supported by the front end portion 60f of the shelf plate 60 provided above the top plate 31. Therefore, the configuration of the upper support member that supports the electronic device E can be simplified.

In addition, as long as it does not deviate from the gist of the present invention, it is possible to select the configuration described in the above embodiment or change it to another configuration as appropriate.

In the embodiment shown above, of the lower support member and the upper support member, the lower support member is configured to move in the opposite direction, but the present invention is not limited to this, and the upper support member moves in the opposite direction. Or may be configured such that both the lower support member and the upper support member move in opposite directions. As a configuration in which the upper support member moves in the opposite direction, for example, a structure in which the shelf contracts the length in the front-rear direction is adopted as the upper support member.

Further, the tray is placed on the top plate, and the shelf plate is provided above the top plate, but the present invention is not limited to this, and the lower support member and the upper support member are attached to the bracket provided on the top plate. It may be provided. Further, the tray may have a robust structure in which both the left and right sides are supported by rails or the like.

Further, in the above-described embodiment, the electronic device E has been described as an example of the lower support member and the object supported by the upper support member, but the present invention is not limited to this. Books such as books and magazines, mirrors, etc. are adopted as objects.

Further, the top plate elevating desk 100 may have any other configuration as long as the top plate 31 can be elevated, such as the configuration, arrangement, and number of legs 1.

Further, the drive motor may be configured in any other configuration as long as the top plate 31 can be raised and lowered.
