The perspective view of the length adjustment components attached to the support | pillar (cylinder) in a prior art example is shown. The frame structure installed in the outdoor veranda etc. is shown. (A) is a schematic perspective view, (b) shows a schematic side view.

First and second embodiments of the length adjustment component of the present invention will be described based on the drawings. Here, it is assumed that a pipe material attached with a length adjustment component is erected between a ceiling and a floor.
FIGS. 1 and 2 show the pipe material 100 to which the length adjustment component 1 of the first embodiment is attached standing between the ceiling 200 and the floor 300.
2 is a screw rod, 3 is a contact member, 4 is a cylindrical member with a bottom, and 5 is a disk-like member. In addition, below, the bottomed cylindrical member is only called "a cylindrical member."
The length adjustment component 1 is composed of a screw rod 2, a contact member 3, a cylindrical member 4 and a disk-like member 5. The discoid member 5 is disposed at the tip of the pipe member 100 as described later.

The screw rod 2 has a male thread groove formed on the outer peripheral portion. This will be described later.
A contact member 3 is attached to the tip of the screw rod 2.
The abutting member 3 is a member that abuts on the ceiling 200 and is composed of the substrate 31 and the cushioning member 32, and the cushioning member 32 serving as a cushioning portion such as a rubber plate or silicone plate is attached to the surface in contact with the ceiling 200. . By doing this, when the abutting member 3 presses the ceiling 200, lateral displacement of the abutting member 3 can be prevented without damaging the ceiling 200. The shape of the contact member 3 may be circular or square.

  The contact member 3 is separated from the rotation of the screw rod 2 so that the contact member 3 does not rotate even if the screw rod 2 rotates. Also, the abutment member 3 is mounted so as to hardly move in the axial direction of the screw rod 2 or attached so as to move slightly in the axial direction of the screw rod 2.

In order to attach the contact member 3 to the screw rod 2, for example, as shown in FIG. 5, the shaft diameter of one end of the screw rod 2 is made smaller than the shaft diameter of the other part. The base member 31 of the contact member 3 having a through hole at a central portion slightly larger than the diameter is attached to this small diameter portion and then the head of the end of the screw rod 2 is crushed to make the contact member 3 You do not have to go out of the bag 2. In addition, the length of the small diameter portion may be slightly larger than the thickness of the substrate of the contact member, and the substrate 31 of the contact member 3 (therefore, the contact member 3) can be inclined about the axis to the screw rod 2. It can also be
The amount of projection of the head of the screw rod 2 which protrudes from the through hole of the substrate 31 of the contact member 3 is made small enough to be absorbed by the contraction of the buffer member 32.
When it is attached to the screw rod 2 so that the surface of the contact member 3 can be inclined, even if the ceiling is inclined, it can contact more appropriately.

  The base 31 of the contact member 3 may have a slightly raised peripheral edge to form a recess for receiving the buffer member 32. In this case, when the contact member 3 is pressed against the ceiling 200, the buffer member 32 must be in contact with the ceiling 200, not this peripheral portion.

The cylindrical member 4 has a bottom and is cup-shaped. The inner diameter of the cylindrical portion is larger than the outer diameter of the disk-like member 5.
The outer diameter of the cylindrical portion of the cylindrical member 4 is thick enough to be gripped with one hand or both hands of a person, and is such that the cylindrical member 4 can be rotated using a hand without using a tool. Do. Therefore, as for the thickness of the cylinder part of the cylindrical member 4, it is desirable to set it as about 30-50 mm approximately.

The cylindrical member 4 is fixed to the screw rod 2 as described below.
As can be seen from FIGS. 1 and 2, when the contact member 3 is at the upper side, the cylindrical member 4 is screwed to the central portion of the bottom of the cylindrical member 4 at a position below the contact member 3. , And fixed so that the opening side of the cylindrical portion of the cylindrical member 4 is disposed downward.

Since the cylindrical member 4 is fixed to the screw rod 2, when the cylindrical member 4 is rotated (forward rotation or reverse rotation), the screw rod 2 is rotated accordingly. By holding the tubular member 4 with one hand or both hands, the operator can easily rotate the tubular member 4 manually.
When the screw rod 2 has the contact member 3 attached to the tip end of the screw rod 2 up, a male screw groove may be formed at a portion below the position where the tubular member 4 is fixed. However, a male screw groove may be formed in a portion between the contact member 3 and the cylindrical member 4.

  The outer diameter of the disk-shaped member 5 is the same as the outer diameter of the pipe member 100 and smaller than the inner diameter of the cylindrical portion of the bottomed cylindrical member 4. Further, a through hole in which a female screw groove to be screwed with the male screw groove of the screw rod 2 is formed at the center of the disc-like member 5. When the screw rod 2 is inserted into the through hole, the screw rod 2 and the disk-like member 5 can be screwed together.

  A nut 51 can be used to form the female screw groove of the disc-like member 5, and in FIG. 1, a circle produced by joining the nut 51 to a disc having a through hole at the center by welding or the like. A plate-like member 5 is shown. In this case, since a female screw groove is formed in the nut 51, it is not necessary to form a female screw groove in the through hole below the nut 51. When the nut 51 is used, a female screw groove can be easily formed in the center of the disk-like member 5.

An annular projection 52 is formed on the rear surface of the disk-like member 5 to be fitted to the end of the pipe member 100. The central hole of the annular projection 52 has a diameter through which the screw rod 2 can be inserted, and the rotation of the screw rod 2 is not impeded.
In order to fit the annular projection 52 to the end of the pipe member 100, for example, the outer diameter of the annular projection 52 is made equal to the inner diameter of the pipe member 100 or the upper surface of the annular projection 52 The outer diameter of (the surface on the side of the contact member 3) is slightly larger than the inner diameter of the pipe material, and the annular projection 52 is tapered toward the lower surface (the surface on the pipe 100) of the annular projection 52 do it.
Therefore, when the disc-like member 5 is disposed so that the center of the disc-like member 5 and the center of the cross-section of the pipe material 100 overlap on the tip end of the pipe material 100, as shown in FIGS. The disc-like member 5 can be attached in a state in which the annular projection 52 is fitted to the end of the pipe member 100.
Here, as described later, the fitting is for preventing the disc-like member 5 from pivoting along with the pivoting of the screw rod 2 along with the pivoting of the cylindrical member 4. There is no need to fit tightly.

The disc-like member 5 is formed, for example, by forming a female screw in a through hole bored in the center of the disc member, and then bonding an annular projection to the back surface thereof by welding or an adhesive or the like The protrusion 52 can be formed and manufactured.
When the nut 51 is used to form the female screw groove of the disc-like member 5, the disc-like member is formed by welding the nut 51 to a disc having a through hole formed in the central portion by welding or an adhesive. 5 can be produced.

  The disc-like member 5 is disposed at a position below the position at which the cylindrical member 4 is fixed in the screw rod 2 when the contact member 3 is up as seen from FIGS. 1 and 2. When the male screw groove of the screw rod 2 and the female screw groove of the through hole of the disk member 5 are screwed, the disk member 5 and the pipe member 100 to which the member 5 is attached The distal end and the subsequent end are made to enter the cylindrical portion of the cylindrical member 4.

  When the cylindrical member 4 is rotated when the contact member 3 is on the screw rod 2, the screw rod 2 is rotated accordingly, and the screw rod 2 is a through-hole of the disk-shaped member 5. You will go up or down inside. At the same time as the screw rod 2 is raised or lowered, the abutment member 3 attached to the screw rod 2 is also raised or lowered. At this time, since the annular projection 52 is fitted to the end of the pipe member 100, the disc-like member 5 is rotated along with the rotation of the screw rod 2 along with the rotation of the cylindrical member 4. There is nothing to do.

As already described, since the inside diameter of the cylindrical part 4 is larger than the outside diameter of the disc-like member 5 and the outside diameter of the disc-like member 5 is the same as the outside diameter of the pipe member 100 The cylindrical portion of the member 4 and the end of the pipe member 100 to which the disk-like member 5 is attached can be loosely fitted.
Thus, since both are loosely fitted, when the cylindrical member 4 is rotated, the screw rod 2 is rotated accordingly, and the tip end portion of the pipe member 100 to which the disk-shaped member 5 is attached and The subsequent end can be smoothly raised or lowered with the inner surface of the cylindrical portion of the cylindrical member 4 as a guide.

When the end of the pipe member 100 to which the disc-like member 5 and the disc-like member 5 are attached is tightly fitted to the cylindrical portion of the cylindrical member 4, the disc-like member is rotated even when the cylindrical member 4 is rotated. 5 and the pipe member 100 rotate so that the screw rod 2 can not be raised or lowered.
For loose fitting, the inner diameter of the cylindrical portion of the cylindrical member 4 is larger than the outer diameter of the disc-like member 5, and the inner diameter of the cylindrical portion of the cylindrical member 4 and the outer diameter of the disc-like member 5 It is desirable to make the difference about 2 mm.

  As described above, since the inner surface of the cylindrical portion of the cylindrical member 4 serves as a guide, the overlap between the cylindrical portion of the cylindrical member 4 and the end portion of the pipe material to which the disk-like member 5 is attached is , It is desirable to maintain it so that it does not disappear although it changes with the rise and fall of screw rod 2.

  When the cylindrical member 4 is rotated in one direction from the state shown in FIG. 1 and the screw rod 2 is moved downward, the inner surface of the bottom of the cylindrical member 4 is the upper surface of the disk 5 (in this case) By contacting with the upper surface of the nut 51, the descent of the screw rod 2 and hence the descent of the contact member 3 is stopped. The state at this time, that is, the state in which the contact member 3 is moved to the lowermost position is shown in FIG. In FIG. 2, the inner surface of the bottom of the cylindrical member 4 is in contact with the upper surface of the nut 51 of the disk-shaped member 5.

  When the cylindrical member 4 is rotated in the direction opposite to the above direction from the state shown in FIG. 2 and the screw rod 2 is moved upward, the cylindrical member 4 and the abutting member 3 Ascending, the abutting member 3 comes in contact with the ceiling 200. The state at this time is shown in FIG. Then, the cylindrical member 4 is further rotated in the same direction, and the rotation of the cylindrical member 4 is stopped when the contact member 3 reaches the state of pressing the ceiling 200. By doing this, the pipe material 100 to which the length adjustment component 1 is attached can be firmly supported and erected between the ceiling 200 and the floor 300.

  If the cylindrical member 4 is rotated from the state of FIG. 2 and the screw rod 2 is raised, the length of the screw rod 2 protruding downward from the lower surface of the disc-like member 5 in FIG. The contact member 3 can be raised. At this time, the bottom surface of the lower end of the screw rod 2 is at the same level as the bottom surface of the disk-like member 5.

As described above, the pipe member 100 to which the length adjustment component 1 of the first embodiment is attached is installed between the ceiling 200 and the floor 300, and the cylindrical member 4 is rotated to contact with the screw rod 2 By raising the member 3 so that the abutting member 3 presses the ceiling 200, the pipe material 100 to which the length adjustment component 1 is attached is erected firmly between the ceiling 200 and the floor 300. Can.
Further, the pipe member 100 to which the erected length adjusting component 1 is attached rotates the cylindrical member 4 in the direction opposite to the direction of the rotation to lower the screw rod 2 together with the contact member 3 , Can be easily removed from between the ceiling 200 and the floor 300.

  Since the length adjustment component 1 of the first embodiment is in a state of being fitted to the front end of the pipe material 100 via the annular projection 52, the length adjustment component 1 is removed from the pipe material 100. Can be done easily by pulling on both. Thus, the length adjustment component 1 can be used repeatedly.

Next, a second embodiment different from the above-described first embodiment will be described based on FIG. 3 and FIG.
The length adjustment component 1 of the second embodiment includes a screw rod 2, an abutment member 3, a first bottomed tubular member 4 and a second bottomed tubular member 5. The second bottomed tubular member 5 is used by covering the end of the pipe member 100 as described later. In the following, the first bottomed tubular member and the second bottomed tubular member will be simply referred to as “first tubular member” and “second tubular member”, respectively.

  The screw rod 2, the contact member 3, and the first cylindrical member 4 of the second embodiment have the same function as the screw rod 2, the contact member 3, and the cylindrical member 4 of the first embodiment. The components of the second embodiment and the arrangement of the components can be the same as those described in the first embodiment, and thus the description thereof is omitted.

The second tubular member 5 has a bottom and is cup-shaped. Then, the inner diameter of the cylindrical portion is larger than the outer diameter of the pipe member 100, and the tip end of the pipe member 100 is covered so that the center of the bottom of the second cylindrical member 5 and the cross-sectional center of the pipe member 100 overlap. It is used.
The outer diameter of the second cylindrical member 5 is smaller than the inner diameter of the first cylindrical member.
Therefore, since the cylindrical portion of the first cylindrical member 4 and the cylindrical portion of the second cylindrical member are loosely fitted, the second cylindrical member 5 is in the cylindrical portion of the first cylindrical member 4. Can enter.

At the central portion of the bottom of the second cylindrical member 5, a through hole in which a female screw groove to be screwed with the male screw groove of the screw rod 2 is formed.
The formation of the female screw groove can be directly formed in the center of the bottom of the second cylindrical member 5, but a nut 51 can be used.
FIGS. 3 and 4 show a second cylindrical member 5 manufactured by welding a nut 51 to a bottom portion having a through hole at the center of a bottomed cylindrical member. In this case, since a female screw groove is formed in the nut 51, it is not necessary to form a female screw groove in the through hole below the nut 51. When the nut 51 is used, a female screw groove can be easily formed in the center of the bottom of the second cylindrical member 5.

As can be seen from FIGS. 3 and 4, when the contact member 3 is on the upper side, the second cylindrical member 5 is lower than the position of the screw rod 2 to which the first cylindrical member 4 is fixed. The open end of the tube portion is disposed at the bottom of the position of. Then, it is screwed into the female screw groove of the through hole formed at the bottom of the second cylindrical member 5 in the male screw groove of the screw rod 2 to turn the screw rod 2 (that is, the first cylindrical member). The second cylindrical member 5 can move up and down in the cylinder of the first cylindrical member 4 in accordance with the rotation). At this time, since the cylindrical portion of the first cylindrical member 4 and the cylindrical portion of the second cylindrical member are loosely fitted, the second cylindrical member 5 is a member of the first cylindrical member 4. With the inner surface of the tube portion as a guide, it can be smoothly raised or lowered.
For loose fitting, the inner diameter of the cylindrical portion of the first cylindrical member 4 is larger than the outer diameter of the second cylindrical member 5, and the inner diameter of the cylindrical portion of the former first cylindrical member 4 It is desirable to make the difference with the outside diameter of the latter second cylindrical member 5 about 2 mm.

Since the cylindrical portion of the first cylindrical member 4 and the cylindrical portion of the second cylindrical member 5 are loosely fitted, when the cylindrical portion of the second cylindrical member 5 is fixed not to rotate, When the first cylindrical member 4 is rotated, the screw rod 2 is rotated, and the second cylindrical member 5 is smoothly raised or lowered with the inner surface of the cylindrical portion of the first cylindrical member 4 as a guide. be able to.
As described above, since the inner surface of the cylindrical portion of the first cylindrical member 4 functions as a guide, the cylinder portion of the first cylindrical member 4 and the cylindrical portion of the second cylindrical member 5 overlap with each other. Although it changes with the rise and fall of screw rod 2, it is desirable to maintain so that it may not disappear.

As described above, the inner diameter of the cylindrical portion of the second tubular member 5 is larger than the outer diameter of the pipe member 100. Therefore, the tip end of the pipe member 100 is covered so that the axial center of the second cylindrical member 5 and the pipe member 100 overlap, and the inner surface of the bottom of the second cylindrical member 5 approaches the upper end of the pipe member 100 Alternatively, when brought into contact with each other, the cylindrical portion of the second cylindrical member and the end portion including the leading end portion of the pipe member 100 are in a loosely fitted state.
For loose fitting, the inner diameter of the second cylindrical member 5 is larger than the outer diameter of the pipe member 100, and the inner diameter of the cylindrical portion of the former second cylindrical member 4 and the pipe member 100 of the latter It is desirable to make the difference with the outer diameter about 2 mm.

  The length adjustment component 1 of the second embodiment uses the second tubular member 5 by covering the tip of the pipe member 100 as described above. Since the second cylindrical member 5 and the pipe member 100 are loosely fitted, even if the pipe member 100 is erected, supported and fixed to the floor 300, the second cylindrical member 5 is a pipe member. It is pivotable about 100 axes. Even if the first cylindrical member 4 is rotated and the screw rod 2 is rotated accordingly, when the second cylindrical member 5 is rotated according to the rotation of the screw rod 2, the screw rod 2 is raised or lowered I can not do it.

  Therefore, using the length adjustment component 1 of the second embodiment, the abutment member 3 of the length adjustment component 1 attached to the tip of the pipe material 100 is raised between the ceiling 200 and the floor 300 Alternatively, in order to lower it, the first cylindrical member 4 must be turned in a state where the pipe member 100 and the second cylindrical member 5 are both restrained and erected on the floor 300 and fixed. .

From the state shown in FIG. 3, the first tubular member 4 is rotated in one direction in a state where the pipe member 100 and the second tubular member 5 are both restrained and erected and fixed on the floor 300. When the screw rod 2 is moved downward, the inner surface of the bottom of the first cylindrical member 4 eventually comes in contact with the upper surface of the second cylindrical member 5 (in this case, the upper surface of the nut 51). The descent of 2 and thus the descent of the abutment member 3 is stopped. The state at this time, that is, the state in which the contact member 3 is moved to the lowermost position is shown in FIG. In FIG. 4, the inner surface of the bottom of the first cylindrical member 4 is in contact with the upper surface of the nut 51 of the second cylindrical member 5.
Further, in a state where the pipe member 100 and the second cylindrical member 5 are both restrained and erected and fixed on the floor 300, the first cylindrical member 4 is rotated in the direction opposite to the above direction. When the screw rod 2 is raised, the contact member 3 is lifted accordingly, and the contact member 3 contacts the ceiling 200. The state at this time is shown in FIG. Then, the first cylindrical member 4 is further rotated in the same direction, and the rotation of the first cylindrical member 4 is stopped when the contact member 3 reaches the state of pressing the ceiling 200. By doing this, the pipe material 100 to which the length adjustment component 1 is attached can be firmly erected between the ceiling 200 and the floor 300.

  In the second embodiment, an annular surface fitted to the front end portion of the pipe member 100 in the same manner as the first embodiment on the inner surface (opening surface) of the bottom surface of the second cylindrical member 5. It is also possible to form a projection. In this case, since the second cylindrical member 5 is not rotated with the rotation of the first cylindrical member 4, the pipe member 100 and the second cylinder are raised when the screw rod 2 is raised or lowered. It is not necessary to restrain the rod-like member 5 together.

In the length adjustment component 1 of the second embodiment, only the second tubular member 5 is placed on the tip of the pipe member 100, and the length adjustment component 1 can be easily removed from the pipe member 100.
In addition, after removing the pipe material 100 with the length adjustment component 1 erected between the ceiling 200 and the floor 300, the length adjustment component 1 removed from the tip of the pipe material 100 may be used again. it can.

  In the above description, the pipe material 100 with the length adjustment component 1 is erected between the ceiling 200 and the floor 300 in any of the first and second embodiments, but with the length adjustment component 1 The pipe 100 can be erected between the ceiling 200 and the top surface of the furniture and used to prevent the furniture from tipping over. Alternatively, it is also possible to bridge the pipe material 100 with the length adjustment component 1 between the wall and the wall. It is also possible to form a shelf by straddling two pipe members with such length adjustment parts.

  Further, as shown in FIG. 8, when installing a solarium with a light-transmissive resin film on a frame structure 400 forming a space on a terrace or the like outdoors, a plurality of support columns of the frame structure 400 are provided.
