Description

  The present invention relates to a fixture for fixing an object to be fixed such as piping without using a bolt.

  Conventionally, U-bolts and saddle bands have been used for fixing brackets for fixing pipes to a fixed body. After the piping was arranged between the U-shaped bolt fixing bodies, the male threaded portion of the U-shaped bolt was inserted into a pair of holes provided in the fixing body and fixed by tightening with a nut. In addition, the saddle band is fixed by tightening a bolt with a nut through a hole provided in the fixed body. However, this operation takes time and effort to install and remove, and a separate tool is required to tighten the nut. Moreover, there is a possibility that the nut may be lost, in which case it cannot be fixed. Therefore, there is a demand for a fixture having as few parts as possible such as bolts. In particular, pipes used for food such as milk and chemicals must be disassembled and cleaned regularly for hygiene purposes, and the pipes must be removed and attached every time they are cleaned. ing. Many fixtures have been developed to improve work efficiency.

  For example, Patent Document 1 discloses a fixture having a male screw portion formed at one end of a U-bolt and a flange portion formed at the other end in a hook shape. According to the present invention, the flange portion at one end is inserted into one of the pair of holes, the male screw portion is inserted into the other hole, and the pipe is fixed to the support by tightening with the nut. It is said that work efficiency can be improved.

  Patent Document 2 discloses a fixing device in which a large number of projections and depressions are formed on the edge in the width direction of at least one end in the longitudinal direction of the belt-like plate, and slits extending in the longitudinal direction are provided from the edges. ing. According to the invention, when fixing the pipe, the other end of the belt-like plate is hooked in the gap, bent along the pipe, and then the pipe is fastened easily and simply by pushing one end of the belt-like plate into the gap. It is supposed to be possible.

  Since the fixing tool of Patent Document 1 has one end of the U-shaped bolt formed in a bowl shape, the work of tightening a nut when fixing a pipe or the like can be reduced to one place, and the work can be reduced as compared with the conventional case. But the other end needs to be tightened with a nut. For this reason, there is no change to the point where a tool is required, and a fixture having a smaller number of parts is desired.

  Moreover, since the strip | belt-shaped board of the fixing device of patent document 2 is a simple structure without a volt | bolt, it is not necessary to clamp | tighten a volt | bolt. It is pushed in and fixed. Therefore, a fixing device that can be fixed without requiring a tool such as a hammer is further desired. Further, the belt-like plate is formed with a large number of irregularities that are caught on the edge of the gap, and it takes time to manufacture the belt-like plate. Therefore, a fixture that can securely fix the tube with a simpler shape is desired.

  In view of the above problems, an object of the present invention is to provide a fixture that can easily and reliably attach and remove an object to be fixed such as a pipe with a simple shape without requiring a tool.

The invention according to claim 1 is a fixture that includes a fixing member for a belt-like plate and a fixing member, and fixes and fixes an object to be fixed between the fixing member and the fixing member. The metal fitting is made of an elastically deformable member, and is formed with a curved portion formed along the shape of the object to be fixed, a horizontal portion extending from the curved portion to both sides and substantially parallel to the surface of the fixed body, and the horizontal portion. A pair of arms that are bent substantially perpendicularly to each other and bent to the opposite sides of the curved portion, and the back of the fixed body at the tip of the arms. A pair of locking portions, the vertical lengths of the pair of arm portions are substantially the same, and the fixed body has a pair of holes through which the locking portions at both ends are respectively inserted. Provided, the maximum distance between the holes is the horizontal distance of the curved portion of the fixing bracket and the distance of the horizontal portion on both sides thereof A fastener, wherein the combined distance is substantially the same.
A second aspect of the present invention is the fixture according to the first aspect, wherein a plurality of pairs of holes are provided in the fixed body, and a plurality of covers are provided between the plurality of the fixing brackets and the fixed body. A fixed object is arranged and fixed.

  According to the fixture of the present invention, it is possible to easily and reliably attach and detach a fixed object such as a pipe with a simple shape without requiring a tool.

In the embodiments described below, the case where the object to be fixed is a pipe will be described as an example. However, the present invention is not limited to this, and can be applied to pipes such as electric pipes, electric cables, and the like. is there.

[overall structure]
FIG. 1 is a perspective view of the fixing device 1 according to the present embodiment after the pipe is attached, and FIG. 2 is a front view showing a mounting portion of the fixing device 1. The fixture 1 of the present invention is composed of a strip-shaped plate fixing bracket 10 and a strip-shaped plate fixing body 20 (also referred to as a support or a plate) to which the fixing bracket 10 is attached. The pipe 30 is arranged and fixed to the pipe. As shown in FIG. 2, the curved portion 11 of the fixing bracket 10 abuts on the pipe 30, the locking portions 14, 14 at both ends of the fixing bracket 10 abut on the back surface of the fixing body 20, and the piping 30 It is stably fixed to the fixed body 20.

[securing bracket]
The fixture 10 of the present invention will be described with reference to FIGS. FIGS. 3 and 4 are a plan view and a front view of the fixture 10 before the pipes are attached, respectively, showing a mounting portion of the fixture 1 shown in FIG. Any material may be used for the fixing metal 10 as long as it is an elastically deformable member, but in this embodiment, a metal plate having a spring property is used. For example, a stainless steel is used as the metal plate having spring properties. A metal wire having a spring property may be used, but a metal plate is more suitable for fixing a pipe because a stronger spring force is applied to the metal plate.

  As shown in FIG. 2, the fixture 10 includes a bending portion 11, horizontal portions 12 and 12 on both sides thereof, a pair of arm portions 13 and 13, and a pair of locking portions 14 and 14 that are tip portions thereof. Consists of. Each part may be integrally formed from a metal plate. Although the dimension of the metal plate material to be used depends on the size of the pipe 30 to be fixed, for example, the lateral width is 8 to 20 mm, the longitudinal width (vertical width) is 40 to 200 mm, and the thickness is 0.5 to 2.0 mm. Degree.

  The bending portion 11 is formed in a substantially semicircular shape along the shape of the pipe 30. In the present embodiment, the curved portion 11 is formed by bending so as to match the curvature of the pipe 30 having an outer diameter of about 6.35 mm to 100.0 mm. As shown in FIG. 2, when each part is integrally formed from a metal plate, the curved part 11 is preferably formed so as to be positioned at the center in the longitudinal direction of the plate material. By forming the curved part 11 in the center part, the horizontal parts 12 and 12 of the both ends, a pair of arm parts 13 and 13, and the latching parts 14 and 14 can be formed symmetrically.

  The horizontal portions 12 and 12 are formed so as to extend from the curved portion 11 to both sides and to be substantially parallel to the surface of the fixed body 20. As shown in FIG. 2, it is preferable to make each length (distance) of the horizontal parts 12 and 12 equal so that the fixing metal fitting 10 is formed symmetrically, for example, about 10-50 mm each. Although details will be described later, as shown in the plan view of FIG. 3, the holes 21 and 21 of the fixed body 20 have a maximum distance W3 between the horizontal distance W1 of the curved portion 11 and the lengths of the horizontal portions 12 and 12. It is formed to be substantially the same as the combined length of W2 and W2.

  The pair of arm portions 13 and 13 are formed by bending from the horizontal portions 12 and 12 substantially vertically and extending. When the arm portions 13 and 13 are formed so as to be bent from the horizontal portions 12 and 12 not substantially perpendicular (right angle) but larger than the right angle, it takes time and effort to pass through the holes 21 and 21 of the fixed body 20, When it is formed to be bent smaller than a right angle, it is easy to be inserted into the hole. However, since the locking of the locking portions 14 and 14 is weakened, it is necessary to be bent substantially vertically.

  As shown in FIG. 4, the arm parts 13 and 13 before the pipe 30 is attached are parallel to the lower side, but after the pipe 30 is attached as shown in FIG. 2, the horizontal parts 12 and 12 are pressed. The arm portions 13 and 13 are also pressed from both sides, bent inward, and locked to the fixed body 20 in an inverted C shape.

  The pair of arm portions 13 and 13 are formed by being bent substantially vertically and extending, and then bent on the opposite side (outside) with respect to the bending portion 11. As shown in FIG. 4, this fold is formed by folding back in a U shape from vertically downward to upward. When the pipe 30 is fixed, the U-shaped portions of the arm portions 13 and 13 are inserted into the holes 21 and 21 of the fixed body 20, so that the lateral width W5 of the hole 21 of the fixed body 20 is the width W4 of the U-shaped portion. Is more widely formed.

  Furthermore, the arm portions 13 and 13 are formed such that the lengths of the locking portions 14 and 14 at the tips of the arm portions 13 and 13 are in contact with and locked to the back surface of the fixed body 20. Here, “the length of contact and locking” means that the pipe 30 is arranged on the fixed body 20 and the arm portions 13 and 13 are perpendicular to the holes 21 and 21 of the fixed body 20 as shown in FIG. When inserted, it is not the length that the locking portions 14 and 14 at the tip end just contact with the back surface of the fixed body 20, but the length (W6) that bites in from the back surface. The engaging portions 14 and 14 do not actually bite into the fixed body 20, but when the pipe 30 is attached, the horizontal portions 12 and 12 are pressed and bent downward from the horizontal direction as described above. However, the arm portions 13 and 13 are also pressed from the outside and inserted into the holes 21 and 21 in a state of being inclined inward from the vertical direction, and the locking portions 14 and 14 with spring force (restoring force) to return to the original state. Is locked to the back surface of the fixed body 20. Therefore, the longer the length W6, the greater the inclination of the arm portions 13 and 13 and the greater the spring force to be locked.However, if the length is too long, the spring force becomes too large to be locked. The distance W6 is preferably about 0.5 to 1.0 mm.

  In the present embodiment, as shown in FIGS. 1 to 4, the lengths of the arm portions 13, 13 are formed to be equal, but may be formed to have different lengths. When the arms 13 and 13 are formed so that the lengths in the vertical direction are equal, it is easy to apply an equal force to the arms 13 and 13 and the fixing work of the pipe 30 can be performed efficiently. Moreover, it is preferable that the vertical lengths of the arms 13 and 13 have a certain length (20 mm or more) so that they can be easily pressed from the outside. The longer the vertical length of the arms 13, 13, the smaller the force pressed from the outside, and the easier it is to tilt. Moreover, when removing, if the vertical direction of the arm parts 13 and 13 is long, it can be easily removed with a small force.

[Fixed body]
Next, the fixed body 20 of the present invention will be described with reference to FIGS. FIG. 5 is a plan view showing an attachment portion of the fixed body before the pipe attachment shown in FIG. 1, and FIG. 6 is a plan view showing an application example thereof.

  As shown in FIG. 1, the fixed body 20 includes an attachment portion 22 to which a pipe 30 is attached and L-shaped support portions 23 and 23 that support the attachment portion 22. The horizontal portions of the L-shaped support portions 23, 23 are fixed to a floor, a wall, a pillar, or the like with screws or bolts (not shown). As with the fixture 10, each part may be integrally formed from a metal plate. The material of the fixed body 20 may be any metal plate material having high rigidity that does not easily deform even when pressure is applied. For example, stainless steel is used.

  The dimensions of the metal plate material when the attachment portion 22 and the support portions 23 and 23 are integrally formed depend on the size of the pipe 30 to be fixed. However, when one pipe 30 is arranged, the lateral width is 50 mm and the length is long. The direction width (vertical width) is about 200 to 300 mm, and the thickness is about 3 mm. The length of the vertical portions of the support portions 23 and 23 is not particularly limited as long as it is longer than the length of the arm portions 13 and 13 of the fixing bracket 10 in the vertical direction. The lengths of the horizontal portions of the support portions 23 and 23 are not particularly limited as long as they are long enough to fix screws and bolts, but are, for example, 25 mm.

  A pair of holes 21 are formed in the attachment portion 22. As described above, the maximum distance W3 between the holes 21 and 21 of the fixed body 20 is substantially the same as the combined length of the horizontal distance W1 of the bending portion 11 and the lengths W2 and W2 of the horizontal portions 12 and 12. (See FIGS. 3 and 5). The maximum distance W3 between the holes 21 and 21 is the horizontal distance of the outermost edge with respect to the position where the pipe 30 is disposed. Although the shape of the holes 21 and 21 is not specifically limited, in this embodiment, it is formed in a rectangular shape as shown in FIG. A rectangular shape with rounded corners may be used. The dimension of the holes 21 and 21 should just be a magnitude | size which the arm parts 13 and 13 of the fixing metal fitting 10 can penetrate, for example, the vertical width (W7) is 12-24 mm, and a horizontal width (W5) is about 3-10 mm.

  Further, as shown in FIG. 6, the fixed body 20 may be provided with a plurality of pairs of holes 21, 21. Although FIG. 6 shows the fixed body 20 when two pipes are fixed, the number of pipes to be fixed may be any number. The dimensions and shape of the fixed body 20 are determined according to the number of the pipes 30 to be fixed. By providing a plurality of pairs of holes 21, 21 in the fixed body 20, a plurality of pipes 30 can be fixed by the single fixed body 20 using the plurality of fixing brackets 10.

[Piping installation method]
Next, a method for attaching the pipe 30 to the fixture 1 of this embodiment will be described with reference to FIGS. 2, 4, and 7. FIG. 7 is an explanatory diagram for explaining a pipe mounting method of the fixture 1 shown in FIG. 1. First, the pipe 30 is arranged at the center of the fixed body 20. Next, the curved portion 11 of the fixture 10 is brought into contact with the pipe 30, and the U-shaped portions of the pair of arms 13 and 13 of the fixture 10 are inserted into the holes 21 and 21 of the fixture 20.

  At this time, the arm portions 13 and 13 may be inserted into the holes 21 and 21 one by one, or both may be simultaneously inserted. As described above, since the lateral width W5 of the hole 21 of the fixed body 20 is formed larger than the width W4 of the U-shaped portion, it can be easily inserted.

  However, as shown in FIG. 4, the locking portions 14 and 14 which are the tips of the arm portions 13 and 13 are formed so as to be outside the holes 21 and 21 by the width W4 of the U-shaped portion, respectively. The arms 13 and 13 cannot be inserted through the holes 21 and 21 in a state of being parallel to the lower side. Therefore, as shown in FIG. 7, the arm portions 13 and 13 are bent by pressing from the direction of arrow A (outside), and the opening angle of the reverse C-shape is changed from parallel to the holes 21 and 21. As shown in FIG. 7, after inserting the arm portions 13 and 13 into the holes 21 and 21 partway, an external force is applied to the U-shaped portion of the arm portions 13 and 13 to narrow the opening angle, and the horizontal portion 12 and An external force is applied to 12 from the direction of arrow B (upper side). At this time, a force corresponding to the spring force is required to press against the spring force of the pair of arm portions 13 and 13 by hand from both sides.

  After the locking portions 14 and 14 which are the tips of the arm portions 13 and 13 are in contact with the back surface of the fixed body 20, an external force is applied to the horizontal portions 12 and 12 in the direction of arrow B, and the piping 30 is connected in the direction of arrow C. And the locking portions 14 and 14 of the arm portions 13 and 13 are locked to the back surface of the fixing body 20. Further, an external force is applied from the arrow A to the U-shaped portions of the arm portions 13 and 13 as necessary. At this time, it adjusts so that it may be latched with the right and left balance as possible. Thereby, the pipe 30 is firmly fixed to the fixed body 20 by the spring force of the arm portions 13 and 13.

  As shown in FIG. 2, the state of the fixture 10 after the pipe 30 is attached is such that the horizontal portions 12 and 12 are pressed and deflected downward, and the arm portions 13 and 13 are also pressed from both sides to form a reverse C shape. It is in a state of being locked to the fixed body 20. When removing the pipe 30 from the fixed body 20, an external force is applied from the arrow A to the U-shaped portions of the arm portions 13, 13 of the fixing bracket 10 to insert the locking portions 14, 14 into the holes 21, 21. By pulling the horizontal portions 12 and 12 upward, the pipe 30 can be easily removed.

  As described above, by using the fixture 1 of the present invention, the pipe 30 can be easily and reliably attached to the fixed body 20 without using bolts or the like, and can be easily detached. Thereby, the work of attaching and detaching the piping 30 can be performed efficiently. Moreover, since tools such as bolts are not used, there is no worry of losing tools.

  As described above, the fixture 1 of the present invention has a simple configuration including the fixture 10 and the fixture 20, and the fixture 10 and the fixture 20 can be integrally formed from a metal plate. Production costs can be reduced. In addition, since the number of parts is small, there is no risk of loss and transportation is easy. Further, when the pipe 30 is fixed by the fixing tool 1, the bolt 30 or the like is not used, and the fixing member 10 is fixed by the spring force of the fixing bracket 10, so that it can be easily and quickly attached. Moreover, the operation | work which removes the piping 30 from the fixing tool 1 is also easy. Therefore, it is particularly useful as a fixture for piping used for foods and medicines such as milk that frequently needs to be attached and removed.

  In addition, the fixture of the Example mentioned above is an example, The structure can be suitably changed in the range which does not deviate from the meaning of invention.
