Utility Model Registration Gazette No. 2518156

  In the tension rod, appropriate support between the wall surfaces is required. That is, when the tension rod is attached between the wall surfaces, the position is not easily displaced, and it is required to reliably maintain the attachment state attached between the wall surfaces. Moreover, the appropriate support according to the various states of a wall surface is also calculated | required. The technique disclosed in Patent Document 1 described above is difficult to cope with.

  An object of the present invention is to provide a tension bar and a tension structure that are less likely to be displaced when attached between wall surfaces and can be reliably attached between wall surfaces.

In one aspect of the present invention, the tension rod is a tension rod attached between two wall surfaces, and includes a rod-shaped portion whose length is variable in the longitudinal direction and a rod-shaped portion along the longitudinal direction of the rod-shaped portion. An urging force applying portion that applies an urging force in a direction in which both ends are separated from each other, an abutting member that is detachably provided at a longitudinal end portion of the rod-like portion, an abutting member that abuts against the wall surface, and an abutting member and the wall fixing part for fixing the member to the wall surface, Ru and a fitting structure for fitting the rod portion and the abutment member. The contact member includes a plate-like portion in which one surface in the thickness direction contacts the wall surface. The fitting structure is provided in the rod-shaped portion, and is provided in the annular first flange portion extending from the end portion of the rod-shaped portion to the contact member side, and in the contact member. It includes an annular second collar portion that extends to the other surface side in the thickness direction and engages with the first collar portion. The plate-like portion is provided along the inner diameter surface of the second flange portion, and includes an extending portion that extends to the other surface side in the thickness direction. The wall surface fixing part is provided in the extension part and includes a through-hole penetrating the plate-like part in the thickness direction.

  According to the strut rod having such a configuration, the contact member that can be attached to and detached from the longitudinal end portion of the rod-shaped portion can be removed from the rod-shaped portion, and the contact member can be fixed in advance by the wall surface fixing portion. Then, the contact member can be reliably fixed to the wall surface. Moreover, since the contact member is being fixed to the wall surface, the possibility that the position may shift can be reduced. And when mounting | wearing with a rod-shaped part to the contact member fixed to the wall surface, a rod-shaped part and a contact member can be fitted and mounted | worn with a fitting structure. Then, the urging force can be applied to the rod-shaped portion more appropriately by applying the urging force in the direction in which both ends of the rod-shaped portion are separated from each other along the longitudinal direction of the rod-shaped portion. Therefore, such a stick is less likely to be displaced when attached between the wall surfaces, and can be reliably attached between the wall surfaces.

  The contact member may include a plate-like portion in which one surface in the thickness direction contacts the wall surface. By carrying out like this, one surface of the thickness direction of plate-shaped parts can be made to contact | abut to a wall surface, and an abutting member can be fixed to a wall surface more appropriately.

  The wall surface fixing portion may be configured to include a through hole that penetrates the plate-like portion in the thickness direction. By doing so, when the contact member is fixed to the wall surface using a screw or the like, it can be fixed using the through hole. Therefore, when fixing a wall surface and a contact member, it can fix more efficiently.

Therefore, it is possible to more reliably attach the tension bar between the wall surfaces.

  Further, the wall surface fixing portion may include a concave portion that is recessed by a predetermined area so as to reduce the thickness of the plate-like portion from the other surface in the thickness direction of the plate-like portion. In this way, when a thumbtack, a pin, a staple needle or the like is used as a fixing member, the abutting member can be more easily fixed to the wall surface using this recess. Therefore, it is possible to improve the efficiency of the attaching work of the tension rod.

  The concave portion may have a rectangular shape when viewed from the thickness direction of the plate-like portion, and the long side may be configured such that the contact member can be fixed with a staple. By doing so, it is possible to reliably drive the staple needle into the wall surface and fix the contact member to the wall surface using the staple needle. In this case, since the direction of fixation by the staple needle can be shown, the contact member can be more firmly fixed to the wall surface.

  A plurality of recesses may be provided at intervals in the direction in which the short side extends. By doing so, it is possible to fix the contact member to the wall surface more firmly, and to more reliably fix the contact member to the wall surface.

  Further, the fitting structure is provided in the rod-shaped portion, and is provided in the annular first flange portion extending from the end portion of the rod-shaped portion toward the contact member side, and in the contact member. You may comprise so that it may include the cyclic | annular 2nd collar part extended in the other surface side of the thickness direction of a part and fitting with a 1st collar part. By carrying out like this, the cyclic | annular 1st collar part and the 2nd collar part can be fitted, and it can be made to fit more reliably.

  The outer shape of the end portion is circular when viewed from the longitudinal direction of the rod-shaped portion, and at least one of the rod-shaped portion and the abutting member is attached to the abutting member mounted on the wall surface. A guide portion for guiding the angle may be provided. By doing so, when the rod-like portion is attached to the abutting member, it can be more reliably attached.

Moreover, it is the magnitude | size which can screw in the trunk | drum 42 of the screw | thread 41 mentioned later. Both the inner diameter surface 36a and the outer diameter surface 36b of the second flange portion 32 extend straight in the longitudinal direction of the rod-shaped portion 12 except for the portion of the inner diameter surface 36a where the extending portions 35a to 35d are provided. Shape.

  The second disk part 32 included in the pad 31a is recessed by a predetermined area so as to reduce the thickness of the second disk part 32 from the other surface 34a in the thickness direction of the second disk part 32. Ten concave portions 38a, 38b, 38c, 38d, 38e, 38f, 38g, 38h, 38i, and 38j are provided as wall surface fixing portions (see FIG. 6). That is, the thickness of the second disc portion 32 in the region where the recesses 38a to 38j are provided is configured to be thinner than the thickness of the second disc portion 32 in the other region. The ten concave portions 38 a to 38 j are provided in the central region of the second disc portion 32. Each of the ten concave portions 38a to 38j has a rectangular shape, specifically, a rectangular shape when viewed from the thickness direction of the second disk portion 32.

  Next, the detail of an example of the attachment between the wall surfaces 19a and 19b of the tension bar 11 having the above-described configuration will be described. FIG. 7 is an external perspective view showing a state in which the pad 31a is attached to the wall surface 19a using screws as fixing members. FIG. 8 is an external view showing a state before the tension bar 11 is attached between the wall surfaces 19a and 19b. FIG. 9 is an external perspective view showing an enlarged region of the grip 14.

  First, referring to FIG. 7 together, a screw 41 as a fixing member is prepared. The screw 41 includes a body portion 42 provided with a thread and a top portion 43 used when the screw 41 is rotated. Using such a screw 41, a driver 44 for rotating the screw 41 is used to attach and fix the pad 31a to the wall surface 19a. In this case, one surface 34b of the second disk portion 32 comes into contact with the wall surface 19a. Specifically, the screw 41 is rotated by the driver 44 so that the body portion 42 is positioned in the through hole 37d, and the pad 31a is fastened to the wall surface 19a. This process is performed in each of the through holes 37a to 37c using the other three screws 41. In this way, the pad 31a is fixed to the wall surface 19a. Further, the pad 31b is similarly fixed to the wall surface 19b in accordance with the position of the pad 31a fixed to the wall surface 19a.

  Next, referring also to FIG. 8, the rod-like portion 12 with the pads 31a and 31b removed is disposed between the pads 31a and 31b fixed between the wall surfaces 19a and 19b. And the rod-shaped part 12 is extended in a longitudinal direction, and the cap 21a and the pad 31a, and the cap 21b and the pad 31b are each fitted. Specifically, the cap 21a is placed on the pad 31a so that the inner diameter surface 28a of the first flange portion 24 of the cap 21a faces the outer diameter surface 36b of the second flange portion 33 of the pad 31a fixed to the wall surface 19a. Fit into. The cap 21b and the pad 31b are similarly fitted.

  Here, when fitting, when the top part 43 of the screw 41 interferes with the projecting parts 29a to 29d and the partition part 26, the rod-like part 12 is rotated to some extent until it does not interfere with the fitting. In this case, a wide area can be secured in the spaces 27b, 27d, 27f, and 27h in which the protrusions 29a to 29d are not arranged. For this reason, it can be made to fit appropriately by arrange | positioning the top part 43 of the screw | thread 41 in this space 27b, 27d, 27f, 27h.

  Then, after the pads 31a and 31b and the caps 21a and 21b provided at both ends of the rod-shaped portion 12 are fitted, the grip 14 is rotated to some degree. If it does so, it can be made to urge in the direction which the both ends of the rod-shaped part 12 leave | separate by the urging | biasing force by the spring 20. In this way, the tension bar 11 is attached between the wall surfaces 19a and 19b.

  According to the tension bar 11 having such a configuration, the pads 31a and 31b that can be attached to and detached from the longitudinal end of the rod-shaped portion 12 are removed from the caps 21a and 21b provided in the rod-shaped portion 12, and the wall fixing portion is previously provided. Pads 31 a and 31 b can be fixed by screws 41. Then, the pads 31a and 31b can be reliably fixed to the wall surfaces 19a and 19b. Moreover, since the pads 31a and 31b are fixed to the wall surfaces 19a and 19b, the possibility that the positions thereof are shifted can be reduced. And when attaching the rod-shaped part 12 to the pads 31a and 31b fixed to the wall surfaces 19a and 19b, the caps 21a and 21b of the rod-shaped part 12 by the first collar part 24 and the second collar part 33 as the fitting structure. And the pads 31a and 31b can be fitted and mounted. Then, the pads 31a and 31b can be more appropriately attached to the rod-shaped portion 12 while applying a biasing force in the direction in which both ends of the rod-shaped portion 12 are separated along the longitudinal direction of the rod-shaped portion 12 by the spring 20. Therefore, when such a tension rod 11 is attached between the wall surfaces 19a and 19b, the position thereof is not easily displaced and can be reliably attached between the wall surfaces 19a and 19b.

  In addition, according to such a structure, it is not necessary to provide what is called a slip prevention mechanism in the both ends of the tension rod 11. FIG.

  Further, according to the present embodiment, since the screws are used as the fixing members, the walls 18a and 18b are made of plywood, and the surface, that is, the wall surfaces 19a and 19b have some unevenness, or the wall surfaces 19a and 19b Even if 19b is in a so-called rough state, the tension bar 11 can be securely attached. That is, when it is attached between the wall surfaces 19a and 19b, its position is not easily displaced, and it can be reliably attached between the wall surfaces 19a and 19b. Such a configuration can be used without significantly reducing the load resistance of the tension bar 11 itself.

  Moreover, according to this embodiment, since one surface 34b of the thickness direction of the 2nd disc part 32 is flat, it can fix more appropriately. In other words, the gaps between the wall surfaces 19a and 19b and the pads 31a and 31b can be eliminated and fixed. Therefore, the pads 31a and 31b can be more securely fixed to the wall surfaces 19a and 19b.

  Moreover, according to this embodiment, since the wall surface fixing part includes the through holes 37a to 37d penetrating the second disk part 32 in the thickness direction, the pad 31a is fixed to the wall surface 19a using the screw 41. The through holes 37a to 37d can be used for fixing. Therefore, when fixing the wall surface 19a and the pad 31a, it can fix more efficiently.

  Further, according to the present embodiment, the pad 31a includes the extending portions 35a to 35d extending to the other surface 34a side in the thickness direction, and the through holes 37a to 37d are provided in the extending portions 35a to 35d. Therefore, when the pad 31a is fixed to the wall surface 19a using the screw 41, the pad 31a can be more reliably held by the screw 41. Therefore, the pad 31a can be more reliably fixed to the wall surface 19a.

  Further, according to the present embodiment, the fitting structure is provided on the rod-shaped portion 12, specifically, the cap 21 a, and extends from the cap 21 a located at the end of the rod-shaped portion 12 to the pad 31 a side. An annular first flange 24 and a pad 31 a are provided on the pad 31 a, extend to the other surface 34 a side in the thickness direction of the second disk portion 32, and engage with the first flange 24. Since the second flange 33 is included, the annular first flange 24 and the second flange 33 can be fitted to each other, and can be more reliably fitted.

  In the above embodiment, the screw 41 is used as the fixing member. However, the present invention is not limited to this, and a staple needle may be used as the fixing member. In this case, a concave portion is used as the wall surface fixing portion.

  Next, the detail of the other example of attachment between the wall surfaces 19a and 19b of the tension bar 11 of an above-described structure is demonstrated. FIG. 10 is an external perspective view showing a state where the pad 31a is attached to the wall surface 19a using a staple needle as a fixing member. FIG. 10 corresponds to FIG.
