Description

  The present invention relates to a spirit level for checking whether or not a handrail is attached vertically when a strut-type handrail is attached between a ceiling and a floor surface.

  2. Description of the Related Art Conventionally, as disclosed in Patent Document 1, for example, there is known a tension type handrail used as a support for a user when the user stands up or sits down. The handrail includes two poles slidable in the longitudinal direction, and a fixture that fixes the poles and sets the overall length to a predetermined length. It can be attached between the ceiling and the floor with the surface stretched.

  By the way, if the handrail as in Patent Document 1 is attached in a tilted state between the ceiling and the floor surface, or if it is misaligned by repeated use and tilted between the ceiling and the floor surface, When the user leans on the handrail, the frictional resistance between the handrail and the handrail or between the floor surface and the handrail may decrease unexpectedly.

  Therefore, when an operator installs the handrail between the ceiling and the floor, or periodically inspects it after installation, the handrail is placed vertically between the ceiling and the floor using a level. It is necessary to check whether it is attached.

  As such a level, for example, as disclosed in Patent Document 2, a level body that extends in a vertical direction having a substantially L-shaped cross section in a plan view, and two orthogonal levels of the level body There is known a level that includes two bubble tubes attached to each of the side surfaces, and a fixing band that can be attached to and detached from each side edge of the level device body.

  And to check the inclination of the handrail using this level, the leveling device body is fixed to the pole with a fixed band by contacting the two inner side surfaces of the leveling device that are substantially perpendicular to the pole. Each of the two bubble tubes of the spirit level is examined to check whether the handrail is inclined.

JP 2008-75383 A (paragraphs 0024-0026, FIG. 1) Japanese Utility Model Publication No. 61-122011 (pages 4, 5 and 1)

  However, in Patent Document 2, when fixing the level to the pole, one end of the fixing band is detached from the level body, and the fixing band is wrapped around the pole with the inner surface of the level body in contact with the pole. Therefore, it is necessary to perform work such as attaching one end to the level body, which is complicated.

  In addition, since the leveler body is fixed by winding the fixed band around the pole, there are many parts where the fixed band and the pole are in contact with each other in the circumferential direction of the pole. Even if an attempt is made to slide up and down to match the line of sight during work, the frictional resistance between the fixed band and the pole outer peripheral surface is high, and the fixed band is difficult to slide integrally with the level body. Therefore, in order for the operator to change the position of the level during the work, it is necessary to attach the level to the appropriate position of the pole again by the above-described procedure, which is inconvenient.

  The present invention has been made in view of such a point, and the object of the present invention is that it can be easily attached / detached to / from the handrail, and the vertical position can be easily adjusted while attached to the handrail. The purpose is to provide an easy-to-use level.

  In order to achieve the above object, the present invention is characterized in that the level is attached to the handrail by sandwiching the pole between the pair of flexible engagement pieces.

  Specifically, it includes two circular poles that can slide in the longitudinal direction, and a fixture that fixes both poles and sets the overall length to a predetermined length. In a level handrail type for checking whether or not a tension-type handrail attached between the ceiling and the floor surface in a state where the ceiling and the floor surface are stretched is vertically installed between the ceiling and the floor surface The following solutions were taken.

  In other words, the first device includes a level body that is detachably attached so as to grip the pole, and two bubble tubes attached to the level body, the level body facing the pole. A concave portion provided on the surface side, open toward the pole, curved corresponding to the pole outer peripheral surface, and having a contact surface in contact with the pole outer peripheral surface in a state where the level body is attached to the pole; Provided on the back surface side of the recess, two orthogonal surface portions orthogonal to each other, mounting holes formed in each of the orthogonal surface portions, to which the bubble tubes are respectively attached, and projecting at both ends on the opening side of the recess Each projecting end extends from the contact surface of the recess to a position beyond the center of the pole, and the distance between the projecting ends is set to be shorter than the diameter of the pole. With Wherein the state and a pair of flexible engagement pieces pressed against the pole outer peripheral surface at the.

  In the second device, in the first device, each of the bubble tubes is configured by sealing a liquid so as to have bubbles inside a cylindrical body that is long in the lateral direction, and bulges laterally from the orthogonal surface portion. It is attached to the attachment hole as described above.

  The third device is characterized in that, in the first or second device, the two bubble tubes are positioned at substantially the same height in a state in which the level body is attached to the pole.

  In the first device, when the spirit level body is pushed to the pole side with the opening of the concave portion of the level body corresponding to the handrail pole, each engaging piece is bent and deformed in a direction away from each other while sliding on the outer peripheral surface of the pole, When the protruding end of each engagement piece is pushed in until it exceeds the center of the pole, it is restored in a direction approaching each other and comes into pressure contact with the outer peripheral surface of the pole. Therefore, the level can be easily attached to the handrail simply by pushing it toward the pole, and the pole is pressed and sandwiched between the engagement pieces, so that the level can be stably attached to the pole. . On the other hand, when the level attached to the handrail is pulled, each engaging piece is flexibly deformed in a direction away from each other while being in sliding contact with the outer peripheral surface of the pole, and approaches each other when the protruding end of each engaging piece exceeds the center of the pole. While being bent and deformed in the direction to restore the original state, the pole comes out of the opening of the recess. Therefore, the level can be easily removed from the pole simply by pulling the level attached to the pole. In addition, when the level is slid vertically with respect to the pole with the level attached to the pole, the engagement pieces open each other, and the friction between each engagement piece and the outer peripheral surface of the pole appears. When resistance is reduced and the level is slid to the target position, the pole is pressed against and pinched with each engagement piece, so the level can be easily slid to the target height, and at the point where it was slid Attaching the level is stable and easy to use.

  In the second device, since the bubble tube bulges from the orthogonal surface portion, the operator can see not only from the side of the bubble tube but also from the diagonally upper side and the diagonally lower side, which is convenient. .

  In the third device, it is possible to see two bubble tubes at the same time without changing the height of the line of sight, which further improves usability.

  An operation lever 16 is pivotally supported by the first ring member 19 so as to be pivotable up and down. When the operation lever 16 is pivoted downward, the operation lever 16 deflects the first ring member 19. The first ring member 19 is spaced upward from the second ring member 20 while reducing the diameter and compressing a spring (not shown) attached to the upper inner side of the first pole 11a.

  Further, a connecting bar 17 is provided between the first ring member 19 and the second ring member 20, and the first ring member 19 is twisted with respect to the second ring member 20 by the connecting bar 17. It is designed to be spaced apart upward without being displaced.

  Then, with the first pole 11a slid upward with respect to the second pole 11b and the floor contact plate 14 and the ceiling contact plate 13 in contact with the floor F and the ceiling Ce, respectively, the operation lever 16 is moved downward. The first ring member 19 having a reduced diameter sandwiches the first pole 11a and is spaced apart from the second ring member 20 together with the sandwiched first pole 11a so that the ceiling contact plate 13 is placed on the ceiling Ce. In this state, the ceiling Ce and the floor surface F are stretched by the two poles 11 so as to be attached between the ceiling Ce and the floor surface F.

  When the handrail 10 is used, the level 1 and the fixture 12 are covered with a resin cover 18 that is opened and closed with a fastener (not shown) (see FIGS. 4 and 5), In particular, the inclination of the handrail 10 can be examined by opening the resin cover 18.

  As shown in FIGS. 2 and 3, the level 1 has a substantially L-shaped resin level 2 in a plan view that is detachably attached so as to hold the pole 11, and the level 2 And two attached bubble tubes 3.

  A concave portion 4 having an opening 4a that opens toward the pole 11 is formed on the leveling body 2 opposite to the pole 11, and the concave portion 4 is a contact surface that is curved corresponding to the outer peripheral surface of the pole 11. 4b, and the contact surface 4b comes into contact with the outer peripheral surface of the pole 11 with the level body 2 attached to the pole 11.

  Two orthogonal surface portions 5 that are orthogonal to each other are provided on the back side of the concave portion 4, and each orthogonal surface portion 5 has a substantially square shape in a side view.

  A horizontal oblong mounting hole 5a extending in the horizontal direction is recessed in the upper half of the orthogonal surface portion 5, and the bubble tube 3 is attached to the mounting hole 5a. The upper surface 2a of the spirit level body 2 is a reference surface, and the mounting hole 5a is formed to be parallel to the upper surface 2a.

  A pair of flexible engagement pieces 6 project integrally from both ends of the recess 4 on the opening 4a side.

  As shown in FIGS. 3 (a) and 3 (b), each of the engagement pieces 6 extends from the contact surface 4b of the recess 4 to a position beyond the center C of the pole 11, and An interval S between the projecting ends 6 a is set to be shorter than the diameter D of the pole 11, and the leveler body 2 is attached to the pole 11 and pressed against the outer peripheral surface of the pole 11.

  The bubble tube 3 is a cylindrical body that is long in the lateral direction, and is configured by sealing a liquid so as to have bubbles B inside the cylinder body.

  The two bubble tubes 3 are respectively attached to the attachment holes 5a so as to bulge laterally from the orthogonal surface portion 5, and have the same level in a state where the level body 2 is attached to the pole 11. positioned. Accordingly, since the bubble tube 3 bulges laterally from the orthogonal surface portion 5, the operator who attaches the above-mentioned strut-type handrail 10 between the ceiling Ce and the floor surface F causes the bubble B of the bubble tube 3 to be directly from the side. Not only can it be seen from diagonally above or diagonally below, it is easy to use. Further, the two bubble tubes 3 can be seen at the same time without changing the height of the line of sight, and the usability is further improved.

  Next, attachment of the level 1 to the handrail 10 will be described.

  First, as shown in FIG. 3A, the level 1 is pushed into the pole 11 side so that the opening 4a in the recess 4 of the level body 2 corresponds to the pole 11 of the handrail 10.

  Then, each engagement piece 6 bends and deforms in a direction away from each other while being in sliding contact with the outer peripheral surface of the pole 11, and when the protruding end 6a of each engagement piece 6 is pushed in until it exceeds the center C of the pole 11, FIG. As shown in b), the outer peripheral surfaces of the poles 11 are brought into pressure contact with each other by being restored in directions approaching each other. Therefore, the level 1 can be simply attached to the handrail 10 simply by pushing it toward the pole 11, and the pole 11 is pressed and sandwiched between the engagement pieces 6 so that the level 11 is attached to the pole 11. Installation can be stabilized.

  Next, removal of the level 1 from the handrail 10 will be described.

  First, from the state of FIG. 3B, when the level 1 attached to the handrail 10 is pulled outward in the radial direction of the pole 11, the engagement pieces 6 are separated from each other while being in sliding contact with the outer peripheral surface of the pole 11. When the projecting end 6a of each engagement piece 6 exceeds the center C of the pole 11, it bends and deforms in a direction approaching each other and is restored to its original state as shown in FIG. At the same time, the pole 11 comes out of the opening 4 a of the recess 4. Therefore, the level 1 can be easily detached from the pole 11 simply by pulling the level 1 attached to the pole 11.

  Next, height adjustment of the level 1 attached to the handrail 10 will be described.
