[0002]
[Prior art]
As a floor fixing method for this kind of furniture, there is known a method in which furniture supported by an adjuster is fixed by a fixing bracket arranged around the adjuster.
As such a conventional floor fixing method, a fixing bracket having a shaft passing portion for partially passing the shaft portion of an adjuster is prepared, and a part of the fixing bracket is inserted in a state where the shaft portion of the adjuster is inserted through the fixing bracket. And a fixture having an opening groove in a part thereof is prepared, and one end is grounded on the floor in a state where the adjuster is grounded, and the adjuster is provided in the opening groove provided on the other end. The other end is disposed above the base of the adjuster while receiving the shaft portion, and one end is fixed to the floor at that position.
[0003]
[Problems to be solved by the invention]
However, the former fixture must be passed through the shaft portion of the adjuster beforehand through its shaft passage. For this reason, it is not possible to fix the furniture using the fixing bracket after positioning the furniture, and there is a problem that the fixing work is extremely inconvenient. On the other hand, the latter fixing bracket can be fixed by applying the fixing bracket after positioning the furniture, but when the adjuster moves in the direction toward the opening end side of the opening groove, it comes off, and in addition, Since the fixing bracket is easily deformed in the periphery, the structure is not sufficient as a structure for accurately preventing movement and falling.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention uses two fixing fittings having an opening groove to suitably balance the convenience of the fixing work and the accurate fixing state.

[0009]
In order to achieve a similar purpose, the above-mentioned configuration is different from that described above, in which furniture supported by the adjuster is fixed to the floor using a pair of fixing brackets. The other end is disposed above the base of the adjuster while receiving the shaft portion of the adjuster in an opening groove provided on the other end and grounding the floor on the other end. The other end is located above the base of the adjuster while receiving the shaft portion of the adjuster in the opening groove provided on the other end in a state where one end is abutted against a part of the one fixing bracket. The opening direction of the opening groove of both fixing brackets is arranged in a different direction to form a shaft passage portion closed between the opening grooves, and in this state, one end side of one fixing bracket is directly grounded to the floor. And fix one end of the other fixing bracket to the one Of is obtained by so as to fix the fixing bracket, one fixed bracket, and forms a crank shape formed by connecting the top wall located in the bottom wall and the other end located on one end side in a standing wall opening The opening direction of the groove is set to a direction orthogonal to the upright wall, and the other fixing bracket includes a top wall and an upright wall that can overlap the top wall and the upstanding wall of the one fixing bracket, and the opening groove has The opening direction is set in the direction parallel to the upright wall, each fixing bracket is attached to an adjuster in a direction orthogonal to each other, and both fixing brackets are fixed at the position where the top walls of both fixing brackets and the upright walls overlap each other.

The floor fixing device shown in FIG. 1 is applied to furniture A such as a server rack, and is arranged at a position where an adjuster 11 supporting a base thereof can be fixed to a floor F. It is composed of
[0013]
Each fixing bracket 2 (3) is formed by plastically deforming a sheet metal material, thereby forming an upright wall 23 between a bottom wall 21 (31) located at one end and a top wall 22 (32) located at the other end. In the crank shape connected by (33), the bottom wall 21 (31) is grounded on the floor F, and the top wall 22 (32) can be arranged above the base 11a of the adjuster 11. I have. Specifically, the top wall 22 has an opening groove 22a which is open on the other end side and extends in a direction orthogonal to the upright wall 23, and receives the shaft portion 11b of the adjuster 11 in the opening groove 22a. When the other end is disposed so as to substantially overlap the upper surface of the base 11a, the bottom wall 21 can be grounded on the floor F. On the other hand, the fixing bracket 3 has an opening groove 32a opened on the side edge side of the top wall 32 and extending parallel to the upright wall 33. The opening groove 32a receives the shaft portion 11b of the adjuster 11 while receiving the other. When the end side is overlapped and arranged on the upper surface of the top wall 22 of the fixture 2 previously arranged, the bottom wall 31 can be indirectly grounded on the floor F via the bottom wall 21 of the fixture 2. I can do it. The opening grooves 22a and 32a are formed at the center of the top plates 22 and 32 and have a semicircular hole having an inner diameter substantially corresponding to the diameter of the shaft portion 11b of the adjuster 11. , 32 at the edges. In other words, the direction in which the fixture 2 approaches the adjuster 1 is orthogonal to the direction in which the fixture 3 approaches the adjuster 1. When the top wall 32 of the fixture 3 is superimposed on the top wall 22 of the fixture 2, the bottom wall 31 and the upright wall 33 are provided with screw insertion holes 21 a and 31 a as floor fixing portions that are continuous with each other. A screw v is inserted into these screw insertion holes 21a and 31a and fixed to the floor F. In this state, the shaft closed between the open grooves 22a and 32a as shown in FIGS. The passage portion X can be formed.

As described above, in the floor fixing device of the present embodiment, the position where each of the fixing brackets 2 and 3 holds the base 11a of the adjuster 1 from above while receiving the shaft portion 11b of the adjuster 1 in the opening grooves 22a and 32a. The fixtures 2 and 3 can be adjusted to a predetermined position of the adjuster 1 without moving the furniture, even if the furniture is previously positioned. Therefore, it is possible to effectively improve the convenience of fixing work to furniture. Moreover, a shaft passage portion X closed by the two fixing brackets 2 and 3 is formed, and the shaft portion 11b of the adjuster 1 can be confined in the shaft passage portion X. Not only can the shaft portion 11b be prevented from coming off, but also the weak portions of the open grooves 22a and 32a in the vicinity of the open ends are complemented by the nearer proximal portions of the mating open grooves 22a and 32a in a superposed state. Therefore, it is possible to realize a strong and accurate fixed state as a whole.
[0015]
In particular, in this embodiment, each of the fixing brackets 2 and 3 has a crank shape, and screw insertion holes 21a and 31a serving as floor fixing portions are provided in a part of the bottom walls 21 and 31, and one of the top walls 22 is provided. Since only the opening grooves 22a and 32a are provided in the portion, not only the structure is simple and easy to operate, but also the function of suppressing the adjuster 1 and fixing it to the floor F is accurately realized without interfering with the adjuster 1. be able to.

In the stopped state, the direction of the opening grooves 22a and 32a provided in the top walls 22 and 32 is made orthogonal to form the closed shaft passage portion X between the opening grooves 22a and 32a. The work efficiency is improved in common with the stopping point, and the gap δ between the bottom face a of the furniture A and the floor F is narrow as shown in FIG. In the case where there is a work space only in the front as in the case of the adjuster 11 (arrow A1 in FIG. 5), the bottom wall 21, 31 can be screwed into the screw insertion holes 21a, 31a by positioning the bottom wall 31, 31 in front. Can be done effectively .
[0017]
As shown in FIG. 6, if a bent reinforcing piece 32 b is provided at the edge of the top wall 32 of the other fixture 3, deformation of the edge, and thus deformation of the opening groove 32 a, is prevented. The fixed state with respect to the adjuster 11 can be made more reliable.
<Second embodiment>
The floor fixing device shown in FIGS. 7 and 8 includes a pair of fixing fittings 102 and 103, but only the top walls 122 and 132 are superimposed, and the bottom walls 121 and 131 are individually fixed directly to the floor F. This is different from the above-described first embodiment in that it is configured as described above.
[0018]
That is, each of the fixing fittings 102, 103 of the floor fixing device is configured such that the bottom walls 121, 131 located on one end side are grounded on the floor F and the opening grooves 122a provided on the top walls 122, 132 located on the other end side. The top walls 122 and 132 are overlapped and arranged above the base 11a of the adjuster 11 while receiving the shaft portion 11b of the adjuster 11 in the adjuster 132, and the opening grooves 122a and 132a of the fixing brackets 102 and 103 are formed. The opening directions are arranged in different directions to form a closed shaft passage portion X between the opening grooves 122a and 132a, and in this state, the bottom walls 121 and 131 of the fixing brackets 102 and 103 are fixed to the floor F. It is what you are doing.
[0019]
For this purpose, each fixture 102 (103) has a crank shape in which a bottom wall 121 (131) and a top wall 122 (132) are connected by an upright wall 123 (133). Is set to be longer than that of the upright wall 123 by the thickness of the top wall 122. A screw insertion hole 121a (131a) serving as a floor fixing portion is provided in a part of the bottom wall 121 (131), and the opening groove 122a (132a) is provided in a part of the top wall 122 (132).
[0020]
The two opening grooves 122a and 132a have their opening directions perpendicular to the upright walls 123 and 133, respectively, and the top walls 122 and 132 of the two fixing brackets 102 and 103 are overlapped with each other so that Using the screw insertion holes 121a and 131a provided in the bottom walls 121 and 131, respectively, it is fixed to the floor F to form a shaft passage portion X closed between the opening grooves 123a and 133a provided in the top walls 123 and 133. I am trying to do it.
[0021]
As shown in FIG. 7 and FIG. 8, the arrangement of the fixing brackets 102 and 103 is such that the adjuster 11 is approached from a direction different by 90 ° and the opening grooves 122 a and 132 a are orthogonal to each other. As shown in FIG. 10, there is a form in which the adjuster 11 is approached from a direction different by 180 ° so that the opening grooves 122a and 132a face each other.
[0022]
7 to 10, the closed shaft passage portion X can effectively support the shaft portion 11 b of the adjuster 11, and the fixed portion is increased, but the shaft portion 11 b is fixed to the floor F. Since the fixing force can be increased by increasing the number of scaffolds, it is possible to realize a secure fixing state of furniture due to an earthquake or the like.
In the case where the orthogonal state as shown in FIGS. 7 and 8 is adopted as the orientation of the opening grooves 122a and 132a in this case, corners of furniture that cannot access the adjuster 11 from the front and rear (for example, the arrow A2 in FIG. 5). In addition, when the facing state as shown in FIGS. 9 and 10 is adopted, the shaft passing portion X becomes a state close to a perfect circle, the fixing strength can be increased, and As the most effective positional relationship to reinforce the parts that are easily vulnerable to each other, the present invention can be applied to various cases in which the adjuster 11 can be accessed from the front and rear, and can be used for the purpose of increasing the fixing strength.
<Third embodiment>
The floor fixing device illustrated in FIGS. 11 and 12 includes a pair of fixing brackets 202 and 203. After fixing one fixing bracket 202 to the floor F, the other fixing bracket 203 is attached to the one fixing bracket 202. This is different from the first and second embodiments in that it is fixed.
[0023]
That is, one fixing bracket 202 of the floor fixing device is configured such that the bottom wall 221 located on one end side is grounded on the floor F, and the shaft portion of the adjuster 11 is inserted into the opening groove 222a provided on the top wall 222 located on the other end side. The top wall 222 is arranged above the base 11a of the adjuster 11 while receiving the top 11b, and the other fixing bracket 203 is used to move the upright wall 233 located at one end to the upright of the one fixing bracket 202. The top wall 232 is positioned above the base of the adjuster 11 while receiving the shaft portion 11b of the adjuster 11 in the opening groove 232a provided in the top wall 232 in a state where the top wall 232 is in contact with the wall 223, and the top wall of the one fixing bracket 202 is provided. The fixing grooves 202 and 203 are arranged at positions overlapping with each other, and the opening directions of the opening grooves 222a and 232a of the fixing brackets 202 and 203 are different from each other. A closed shaft passing portion X is formed between 2a and 232a, and in this state, the bottom wall 221 of one fixing bracket 202 is fixed to the floor F, and the upright wall 233 of the other fixing bracket 203 is connected to the one of the one fixing bracket 203. The fixing bracket 202 is fixed to the upright wall 223.
[0024]
To this end, one of the fixing brackets 202 is formed in a crank shape in which a bottom wall 221 and a top wall 222 are connected by an upright wall 223, and the other fixing bracket 203 is a top of the one fixing bracket 202. It is a channel having a top wall 232 and an upright wall 233 which can be superimposed on the wall 222 and the upright wall 223, and the upright walls 223, 233 of both fixing brackets are fixed to them at their overlapping position. The parts are connected to each other using the screw insertion holes 223a and 233a.
[0025]
The orientation of the opening grooves 222a and 232a is set so that the opening direction of the former is orthogonal to the upright wall 223 and the opening direction of the latter is parallel to the upright wall 233.
Even with such a configuration, the shaft portion 11b of the adjuster 11 can be securely sandwiched and supported by the shaft passage portion X closed between the opening grooves 222a and 232a, and the furniture can be displaced in the horizontal direction or fall down Can be effectively prevented.
[0026]
Moreover, the fixing brackets 202 and 203 themselves have a very simple structure such as a crank shape and a channel shape, and the number of directly fixing portions to the floor F can be reduced, so that the fixing operation can be simplified. It becomes.
In this embodiment, the other fixing member 203 is formed in a channel shape, but may be formed in an angle shape or the like if the strength is not affected.
[0027]
As described above, several embodiments of the present invention have been described. However, the specific configuration of each unit and the like can be variously modified in addition to the above-described embodiments without departing from the spirit of the present invention. In the drawings, the fixing brackets are squared for convenience, but these are actually made by bending a sheet metal material.
[0028]
【The invention's effect】
The present invention is implemented in the form described above, and has the following effects.
In other words, the furniture floor fixing device according to the present invention is such that one end is directly or indirectly grounded on the floor, and the other end is positioned above the base of the adjuster while receiving the shaft of the adjuster in the opening groove provided on the other end. By using a pair of fixing brackets configured to be arranged in the same direction, the opening directions of the opening grooves of both fixing brackets are arranged in different directions from each other to form a shaft passing portion closed between the opening grooves, and in this state, both shafts are formed. One end of the fixing bracket is fixed to the floor, and each fixing bracket connects a bottom wall located at one end side and a top wall located at the other end side with an upright wall. A floor fixing part is provided in a part of the bottom wall, an opening groove is provided in a part of the top wall, and the opening direction of the opening groove of one fixing bracket is a direction orthogonal to the upright wall, and opening direction of the opening groove of the fixing bracket in a direction parallel to the upright wall of the fixing bracket Attached to the adjuster in the direction orthogonal to each other, the bottom wall of both the fixing bracket, while being polymerized top wall and between upright wall together, to stop co floor fixing portion provided in the bottom wall, provided top wall The closed shaft passage portion is formed between the open grooves .
[0029]
For this reason, after the furniture is positioned first, the fixture can be attached to the adjuster using the opening groove without moving the furniture, and the convenience of the fixing operation can be effectively improved. In addition, since the shaft passing portion closed by the two fixing brackets is formed, and the shaft portion of the adjuster can be surrounded by the shaft passing portion, even if a roll occurs in any direction during an earthquake or the like, the shaft passing from the opening groove. Of the adjuster can be effectively prevented, and the parts that are easily vulnerable to each other in the superposed state are reinforced to increase the deterrent against falling. It is possible to do.
[0030]
In addition, not only the structure is simple and the operation is easy, but also it is possible to suppress the adjuster and fix it to the floor accurately without interfering with the adjuster.
In this case, by fixing both fixing points at the same time, the number of fixing points is reduced and the work efficiency is improved.Also, when the gap between the floor of the furniture and the floor is narrow and there is only a work space in front, the floor By locating the fixing portion in front of it, a working place can be effectively secured.
[0031]
On the other hand, the positional relationship between the opening direction of the opening groove of both fixing brackets and the upright wall is defined in the same relation, and the bottom wall of each fixing bracket is directly If the floor fixing portions provided on the floor are grounded and fixed directly to the floor, respectively, and fixed to the floor to form closed shaft passage portions between the opening grooves provided on the top wall, the number of fixing portions increases. However, it is possible to reliably increase the fixing force by increasing the number of scaffolds on the floor.
[0032]
In this case, the orientation of the opening groove may be one in which the opening grooves of both the fixing brackets are orthogonal to each other. In this case, it is useful to apply to a corner of furniture or the like where the adjuster cannot be accessed from the front and rear.
[0033]
As another configuration different from the above, one fixing bracket is fixed to the floor in the same manner as described above, and the other fixing bracket is fixed to one fixing bracket, and each fixing bracket is orthogonal to each other. The same operation and effect as described above can be obtained even when the configuration is such that it can be attached to the adjuster in the direction .
In this case, one of the fixing brackets has the same crank shape as described above, and the other fixing bracket has a form in which the top wall and the bottom wall can be superimposed on the one fixing bracket, such as a channel-like or angle-like one. Then, the required fixing function can be realized without impairing the simplification of the structure.
[0034]
If the direction of the opening groove at that time is such that the opening groove of one of the fixing brackets is in a direction perpendicular to the upright wall and the opening groove of the other fixing bracket is in the direction parallel to the upright wall, the intended purpose is appropriately determined. Can be realized.
In the above, if a bent reinforcing piece is provided at the edge of the top wall of the fixing fitting in the shape of a crank or an angle, the deformation of the edge can be prevented and the fixed state can be made more reliable. .
