Description

  The present invention relates to a connecting table in which a sleeve wagon provided with casters can be freely arranged (hereinafter referred to as a wagon-free) at an arbitrary position under the top plate, and more specifically, a wagon-free connection characterized by the structure of the desk frame. Related to the desk.

  With regard to a free address type connecting desk that allows a person to arrive at an arbitrary position of a desk and use the desk, many proposals have been made from the past, including Patent Documents 1 to 3, and some are in practical use. However, there is no so-called wagon-free connecting desk that can be freely placed at any position below the top plate up to the sleeve wagon.

  The proposed free address connecting desk is a type of connecting desk (hereinafter also referred to as a double-sided type) in which a plurality of top boards are provided in the length direction and the top boards are arranged facing each other. Therefore, a structure having a substantially T-shaped side section including a leg supporting the top plate and a top plate support arm, that is, a desk frame is arranged directly below the top plate to be faced, and the top plate support arm of this T-shaped frame It has a basic structure that supports and mounts a top plate that faces the dome. In addition, panel-like legs are attached to both ends of the connecting top plate to ensure the independence of the connecting desk.

  As for the known free address connecting desk, the top boards are arranged facing each other as described above, and the top boards are connected in the length direction, that is, the double-sided type. The plane projection area it occupies is quite large, and therefore it is necessary to have a room with a considerably large floor area in order to arrange such a connecting desk.

  However, depending on the size of the room and the layout of the connecting desk in the room, it is not a double-sided type connecting desk, that is, a single-sided wagon-free connecting desk that the top plate is connected only on one side instead of facing. There is much demand.

  However, in the single-sided wagon-free connecting desk, the leg and the top support arm are included under the top on the opposite side in the depth direction of the top connected in the length direction (the side opposite to the side where the person arrives). Since the desk frame is arranged, the overall length of the connecting top plate is increased, for example, a long single-sided top plate having at least 6 to 8 m or more connecting at least 3 to 4 top plates having a length of at least 2 m. It has been found that there are cases in which the desk cannot be used stably with the wagon-free connecting desk that it has.

That is, if a person is biased to work on one side in the longitudinal direction of the single-sided type connection top plate, the desk frame is twisted, and the other side of the frame floats up and down from the floor. Conventionally, in a single-sided connection desk, the problem of leg lift due to the twisting of the desk frame has not been studied at all. This is because there was no single-sided wagon-free connecting machine having a length of the rolling top plate of at least 6-8 m.
In a single-sided connection desk, if the front / rear width of the desk frame is increased, the frame is less likely to be twisted, and it may be possible to prevent lifting, but if the front / rear width of the desk frame is increased, There is a possibility that it cannot be used as a wagon-free connecting desk because the width of the front and rear of the space is reduced.
Japanese Patent No. 378536 JP-A-5-228024 JP-A-8-187128

  Accordingly, an object of the present invention is to provide a wagon-free connecting desk provided with a frame structure suitable for a single-sided wagon-free connecting desk.

The structure of the connecting machine of the present invention made for the purpose of solving the above-mentioned problem is that the left and right structural frames formed in a substantially vertically-shaped shape with two vertical members and two horizontal members, which are steel materials, Is formed by joining a duct-like structure extending in the left- right direction and a steel beam extending in the left-right direction , formed of a steel material having a substantially L shape, and at least two of the core frames are connected to the core frame. An intermediate leg made of steel with a top plate support arm that supports two side portions of two adjacent top plates that are arranged between each other and that are adjacent to each other and that extends in the front-rear direction, and is arranged at the outer end of the core frame The structural frame of the core frame is firmly coupled to a steel end leg provided with a top plate support arm that supports the side portion of the top plate and extends in the front-rear direction by a coupling means such as bolt fastening. Frame structure It is formed and is supported at least two of the top plate at least three stage support arm in the frame structure, and the steel Haritai, the horizontal member and the front of the upper of the left and right structural frame The corner portions formed by the vertical members are joined together, and the duct-like structure joins the L-shaped portions formed by the lower transverse members and the rear longitudinal members of the left and right structural frames. It has a side cross-sectional L-shaped part, and this L-shaped part has a length in the height direction that is the same as the length in the front-rear direction of the structural frame and the length in the front-rear direction of the horizontal part. It is formed by a long vertical part .

In the structure of the above-mentioned connecting desk, the upper part of the vertical part is formed in a U-shaped cross section that is bent horizontally toward the front and then vertically bent downward, and the front of the horizontal part is vertically bent vertically upward. It can be formed as a front part having a lower height than the part, and the upper part of the front part can be formed in a U-shaped cross-section that is bent horizontally rearward and then vertically downward.

According to the present invention, the desk frame does not bend or twist even if it is a long single-sided connecting desk in which three or more top plates of 2 m or more are connected. Therefore, even if a person approaches to one side of the top board, the end leg on the other side of the desk frame does not float off the floor, which is suitable as a single-sided wagon-free connecting desk.

Next, an example of an embodiment of the connecting desk of the present invention will be described.
FIG. 1 is a perspective view of a left end portion of an example of the connecting desk according to the present invention under a top plate, FIG. 2 is a perspective view of the intermediate portion under the top plate, FIG. 3 is a side sectional view of a core frame, and FIG. 5 is a perspective view of an example of the connecting desk of the present invention.

The core frame CF in the illustrated connecting device of the present invention has the following configuration.
1 to 3, reference numeral 1 denotes a structural frame body of a core frame CF. Here, a steel square pipe or a mold (hereinafter simply referred to as a “square pipe”) is used as a vertical member 1a and a horizontal member 1b. The members 1a and 1b are assembled in a substantially square shape and fixed by welding or the like to form the square shape.

In the present invention, the left and right frame bodies 1 are arranged by appropriately separating the left and right frame bodies 1 (this separation distance corresponds to the span (front width) of the top plates 13 and 14 to be described later). , 1 are arranged at the upper right even portion in FIG. 3, and the front and rear longitudinal members 1a, 1a and the lower horizontal member 1b are centered on the lower left even portion of the frame 1, 1. The core frame CF is formed by being joined by a duct-like structure 3 having a substantially L-shaped cross section made of a steel plate arranged with respect to the lower part of the steel plate. That is, the steel beam body 2 extends in the left-right direction and joins corners formed by the upper horizontal member 1b and the front vertical member 1a of the left and right structural frames 1. The duct-like structure 3 extends in the left-right direction and has an L-shaped side cross section that joins L-shaped portions formed by the lower horizontal member 1b and the rear vertical member 1a of the left and right structural frames 1. Part. The L-shaped portion is formed of a horizontal portion having the same length as the length of the structural frame 1 in the front-rear direction and a vertical portion having a length in the height direction longer than the length of the horizontal portion in the front-rear direction. Further, the upper part of the vertical part is formed in a U-shaped cross section that is bent horizontally toward the front and then vertically bent downward. The front part of the horizontal part is formed as a front part having a height lower than that of the vertical part bent vertically upward. The upper portion of the front surface portion is formed in a U-shaped cross section that is bent horizontally backward and then vertically bent downward . The connecting means for each member may be any means such as welding, tacking or screwing. Reference numeral 4 denotes four bolt holes opened above and below the two vertical members 1a in the structural frame 1.

  The core frame CF is formed into a single-sided desk frame structure using at least two core frames CF. The desk frame structure using at least two core frames CF uses an intermediate leg CL disposed between the core frames CF and an end leg EL disposed at an outer end of the core frame CF. It is formed by firmly bonding to.

  As shown in FIG. 4, the intermediate leg CL and the end leg EL are, as an example, two leg pillars 5 and 6 made of steel square pipes standing in parallel, and the upper and lower ends thereof being square pipes. It is formed into a structural leg by connecting with cross members 7 and 8 made of steel or mold steel. In the structural legs illustrated in FIG. 4, the two leg columns 5 and 6 are arranged with a width equal to or slightly larger than the separation width of the two vertical members 1a of the core frame CF, The form is fixed by the materials 7 and 8. Here, the intermediate leg CL has a front width (left-right width as viewed from the left or right side in FIG. 4) that is approximately twice the front width of the end leg EL. This is because the intermediate leg CL has two top plates on both the left and right sides, whereas the end leg EL supports only one top plate.

  A top plate support arm 9 is fixed to the upper cross member 7 in the structural leg by inserting the tip side thereof. The fixing means for the members 5 to 9 in the structural leg may be the same technique as that for fixing the constituent members of the structural frame 1 described above. In addition, 10 is an adjuster provided at the lower ends of the pillars 5 and 6, 41 is a bolt hole provided in the leg pillars 5 and 6 so as to coincide with the four bolt holes 4 provided in the structural frame 1. is there.

  At least two of the core frames CF, the intermediate leg CL, and both end legs EL are firmly tightened with nuts (not shown) by inserting bolts 11 into the bolt holes 4 and 41 provided in them. Thus, a desk frame structure having strong rigidity coupled to one in the connection desk of the present invention is formed.

  At the left and right outer ends of the above-mentioned desk frame structure, as an example, panel legs 12 are attached to the outer surface of the end legs EL by bolting or the like, so that a stand-alone desk frame structure is formed. By mounting and fixing the top plates 13 and 14, the connection desk of the present invention illustrated in FIG. 5 is formed. In FIG. 5, 15 is a long hole for taking out (injecting) the wiring formed on the opposite side of the top plates 13 and 14, and 16 is a lid covering the long hole 15 for wiring. These wires are held at the bottom of the duct-like structure 3 that forms the core frame CF. The bottom of the duct-like structure 3 is appropriately provided with a hole (not shown) for taking in wiring from the floor or for drawing out wiring to the floor side.

  In the wagon-free connecting desk of the present invention shown in FIG. 5, the panel legs 12 provided at the left and right ends are configured such that the front side 12 a protrudes to the front side from the front side sides of the top plates 13 and 14. This is because, when an unbalanced load (for example, a load on the front side of the top plate) is applied to the long top plates 13 and 14, the top frame is coupled with the rigidity of the desk frame structure that is firmly connected and integrated. This is because the bending of the plate is suppressed and the desk frame structure is prevented from being subjected to a twisting force due to an offset load.

The present invention is as described above, and the desk frame does not bend or twist even if it is a long single-sided type connecting desk in which three or more top plates of 2 m or more are connected. Therefore, even if a person comes to one side of the top board, the end leg on the other side of the desk frame does not float off the floor.
