[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In this embodiment, as shown in FIGS. 1 to 4, the furniture main body A of the long bobbin furniture has a plurality of vertically arranged supporting portions A1 of a bobbin B made of synthetic resin or corrugated cardboard. Are arranged in two stages, and these support portions A1 are constituted by a pair of front and rear support shafts 4 and 4 in parallel, and a plurality of bobbins B are placed and displayed in the left and right direction, respectively. This shows a case where a hose is pulled out by a necessary length forward as a wound long object C.
[0009]
In each support portion A1 of the fixture main body A, an abutting rod 1 for preventing the bobbin B from rolling and falling is provided horizontally at a position higher than the support shafts 4 and 4 in the pulling-out direction of the long object C. You.
[0010]
The striking rod 1 is supported movably in the up-down direction with respect to the furniture main body A, and an engagement surface 2a facing the fixing surface A2 of the furniture main body A is continuously provided on the furniture main body A side. Then, the engaging surface 2a and the fixing surface A2 of the furniture main body A are pressed against each other so that the abutting rod 1 cannot be moved at least in the direction in which the long object C is pulled out, and the abutting rod 1 is moved downward. In the non-installed state after the movement, the bobbin replacement opening S is formed in the direction in which the long object C of the bobbin B is pulled out.
[0011]
In the case of the present embodiment, the abutting rod 1 is a rod-like body, and this rod-like body is fixed to the left and right ends 2c, 2c of the bracket 2 bent and formed in a U-shape by, for example, screws. Both end surfaces of the left and right end portions 2c, 2c are opposed to the fixing surface A2 of the furniture main body A to form an engaging surface 2a, and the fixing surface A2 of the furniture main body A is a vertical front surface of the column.
[0012]
Then, the bracket 2 connected to the butting rod 1 is supported so as to be vertically reciprocable by connecting means 3 comprising a long hole 3a and a support shaft 3b movably inserted therein, as shown in FIGS. 1 and 3 ( As shown in a), in the installation state in which the butting rod 1 and the bracket 2 are linearly moved downward along the elongated hole 3a, the engaging surface 2a of the bracket 2 and the fixing surface A2 of the furniture main body A are The contact rod 1 is pressed so as to be immovable in the direction in which the long object C is pulled out and further downward.
[0013]
Further, in a state where the butting rod 1 and the bracket 2 are linearly moved to the upper limit position, as shown in FIGS. 1 and 3B, along the arc surface 2b continuously formed at the lower end portion of the engagement surface 2a. The striking rod 1 and the bracket 2 are rotatably supported in the vertical direction, and the striking rod 1 is pivoted to the lower limit position by pivoting downward to open the bobbin replacement opening S.
[0014]
In the case of the illustrated example, as shown in FIG. 4, long holes 3a of the connecting means 3 are vertically formed in left and right ends of the bracket 2 respectively, and support plates 3c facing the left and right ends of these brackets 2 are formed. A support shaft 3b, for example, a screw protruding from the support plate 3c is fixedly attached to the support of the furniture body A, and is vertically and freely rotatably inserted into the elongated hole 3a. The engaging surface 2a of the striking rod 1 is slid along the vertical fixing surface A2 of the fixture main body A by the vertical reciprocation of 3b.
[0015]
Further, if necessary, in order to smoothly slide the abutment rod 1 and the bracket 2 by the elongated hole 3a and the support shaft 3b, the up-and-down movement and the rotation, a metal material is provided between the elongated hole 3a and the support shaft 3b. Alternatively, a collar 3d made of a synthetic resin may be interposed.
[0016]
In the case of the illustrated example, the pair of front and rear support shafts 4 and 4 constituting the support portion A1 are mounted so that the support shafts 4 and 4 cannot be rotated by fixing means 4a such as screws so that they cannot rotate. The bobbin B is slidably supported by pulling out the long object C by making point contact with the outer periphery B1 of the bobbin B to be placed. However, the present invention is not limited to this. May be rotatably supported.
[0017]
Furthermore, these support shafts 4 and 4 can be detachably attached to one of the support shafts 4 and 4, for example, the rear support shaft 4 in the illustrated example, in response to a change in the size of the bobbin B placed thereon. By mounting and adjusting the distance between them in the front-rear direction, it is possible to mount various types of bobbins B having greatly different diameter sizes.
[0018]
Further, a transparent holder 5 is fixed to the front surface of the left and right intermediate portion 2d of the bracket 2, and the price, features, precautions for use and the like of the hose wound as a long object C are described in this holder 5. The price card (not shown) is exchangeably mounted.
In the illustrated example, as shown in FIG. 1, the price card attached to the holder 5 is made easier to see by supporting the left and right intermediate portions 2 d of the bracket 2 with respect to the furniture main body A while being inclined.
[0019]
Next, the operation of the long bobbin furniture will be described.
First, in the installation state of the butting rod 2 shown by the solid line in FIG. 1 and the two-dot chain line in FIG. 3 (a), the engagement surface 2 a of the bracket 2 connected to the butting rod 1 and the fixing of the fixture main body A are fixed. The surface A2 is pressed against the striking rod 1 so that the striking rod 1 cannot be moved in the direction in which the long object C is pulled out.
[0020]
As a result, the bobbin B rolls forward as the long object C is pulled out and hits against the abutting rod 1, so that the bobbin B is immovably supported even if a load is applied to the bobbin B, so that the bobbin B does not drop.
[0021]
In the non-installation state in which the butting rod 1 and the bracket 2 are turned downward as shown by the two-dot chain line in FIG. 1 and the solid line in FIG. The bobbin replacement opening S is formed in the pull-out direction of C, so that the bobbin B can be taken out without contacting the abutting rod 1 without lifting the bobbin B.
[0022]
As a result, it is possible to reliably prevent the bobbin B from being dropped while easily replacing the bobbin B.
In particular, in the case of the present embodiment, by rotating the bracket 2 downward, the left and right central portions 2b and the holder 5 fixed thereto do not protrude forward of the fixture main body A, and the bobbin B can be safely replaced. At the same time, the holder 5 that covers the support portion A1 of the bobbin B in the installed state is retracted below the upper end of the support shaft 4, so that the bobbin B can be reliably replaced.
[0023]
Further, in the case of the present embodiment, the abutment rod 1 and the bracket 2 shown in a two-dot chain line in FIG. The mating surface 2a and the fixing surface A2 of the fixture body A are pressed against each other so that the abutment rod 1 cannot be moved in the pulling-out direction of the long object C.
[0024]
Thus, the abutment rod 1, the bracket 2, and the holder 5 do not naturally lift due to, for example, vibrations due to the weight of the bracket 5, and the bracket 2 moves along the arc surface 2b formed continuously at the lower end of the engagement surface 2a. And the butting rod 1 does not rotate downward and does not descend to the lower limit position.
[0025]
As a result, there is an advantage that the bobbin replacement opening S can be prevented from being carelessly opened.
[0026]
On the other hand, FIG. 5 shows another embodiment of the present invention.
This configuration is such that the upper end edges of the left and right intermediate portions 2d of the bracket 2 are bent toward the engagement surface 2a, and the front end thereof is integrally formed with a rod 1 'as shown in FIGS. Unlike the embodiment, the other configuration is the same as the embodiment shown in FIGS.
[0027]
Therefore, the embodiment shown in FIG. 5 can obtain the same operation and effects as those of the embodiment shown in FIGS.
In particular, in the case of the illustrated example, the upper end edge and the lower end edge of the left and right intermediate portion 2d of the bracket 2 are each bent and integrally formed into a U-shaped cross section, so that the bending strength of the left and right intermediate portion 2d is improved. There is an advantage that the entire bracket 2 can be reduced in weight because it is not easily deformed and hardly bent and deformed even if its thickness is reduced.
[0028]
In the above-described embodiment, the furniture main body A of the long bobbin furniture has a plurality of vertically arranged support portions A1 including a pair of front and rear support shafts 4 and 4. However, the present invention is not limited to this. Other structures, such as disposing the support portion A1 in only one stage in the vertical direction, may be used.
Further, although the hose is wound around the bobbin B as the long object C, the present invention is not limited to this, and a wire rod other than the hose may be used.
[0029]
Further, the connecting means 3 is constituted by a long hole 3a formed in the left and right ends of the bracket 2 and a support shaft 3b protruding from a support plate 3c facing the left and right ends of the bracket 2, but is not limited thereto. For example, although not shown, for example, a long hole 3a may be formed in the support plate 3c in a vertically long shape, and the support shaft 3b protruding from the lower ends of the left and right ends of the bracket 2 may be inserted into the long hole 3a. Operation can be obtained in the same manner as in the above-described embodiment.
[0030]
【The invention's effect】
As described above, according to the first aspect of the present invention, in the installed state, the engaging surface 2a of the abutment rods 1 and 1 'and the fixing surface A2 of the fixture body A are fixed to the abutment rods 1 and 2'. The bobbin B rolls as the long object C is pulled out, and moves even when a load is applied to the abutting rods 1 and 1 'by pressing the long object C so that it cannot move in the pulling direction of the long object C. In the non-installed state in which the bobbin B is not supported and the butting rods 1 and 1 'are moved downward, the bobbin B is formed by forming the bobbin replacement opening S in the direction in which the long object C of the bobbin B is pulled out. Can be taken out without contacting the abutment rods 1 and 1 'without lifting the bobbin B, so that the bobbin B can be easily replaced and fall can be reliably prevented.
Therefore, the bobbin replacement work is easier and more convenient than the conventional one that requires the work of attaching and detaching the butting rod every time the bobbin is replaced, and the need for raising the bobbin high is eliminated, so that the entire fixture can be made compact. Thus, effective use of space and reduction of manufacturing cost can be achieved.
[0031]
According to the second aspect of the present invention, in addition to the effects of the first aspect, the abutting rods 1, 1 'are linearly moved downward along the long holes 3a in an installed state. By pressing the engaging surface 2a and the fixing surface A2 of the fixture body A such that the abutting rods 1 and 1 'cannot move in the pulling-out direction of the long object C, the abutting rods 1 and 1' are pressed. Due to its own weight, it does not rise naturally due to, for example, vibrations, and the abutment rods 1, 1 'do not rotate downward along the arc surface 2b formed continuously at the lower end of the engagement surface 2a. Since it does not descend to the position, it is possible to prevent the bobbin replacement opening S from being opened carelessly.
Therefore, it is safe.
