Japanese Patent No. 4167990

However, in Patent Document 1, after adjusting the handrail holding member so as to have a predetermined angle with respect to the bracket body, the fastening nut must be tightened with a tool to the fastening bolt penetrating the handrail holding member and the concave member. There is a problem that tightening work for tightening the fastening nut to the fastening bolt is required, and as a result, it takes time to assemble the handrail bracket.

An object of the present invention is to provide a handrail bracket that enables easier and shorter time to assemble a handrail to a building material portion.

The present invention is a handrail bracket for fixing a rod-shaped handrail to a building material portion, and forms a cup shape having a hemispherical convex surface, and holds the handrail in a state of receiving the end portion of the handrail from an opening. A concave member having a handrail holding member and a concave surface having a shape corresponding to the convex surface and receiving the handrail holding member so as to be displaceable along the concave surface, and a connecting member for connecting the handrail holding member and the concave surface member. The bracket main body is provided with a bracket body into which the handrail holding member and the concave member joined by the coupling member are incorporated, and a regulating member for restricting the displacement of the handrail holding member with respect to the concave member, and the bracket main body is half. The concave member and the handrail holding member are held in a state where the concave member is sandwiched between the first and second bracket portions, which are divided into split shapes, and the connecting member is the handrail. The regulating member includes a shaft member penetrating the holding member and the concave surface member, and a retaining member for preventing the handrail holding member and the concave surface member from coming off with respect to the shaft member. When the two bracket portions are united, the force in the direction in which the handrail holding member and the concave member are relatively close to each other, which is interposed between the retaining member and the concave member, is applied to the handrail holding member and the concave member. It is given to one of the concave members. This configuration solves the above problems.

According to this configuration, the handrail holding member is appropriately slid along the concave surface of the concave member so that the handrail holding member is adjusted to a predetermined angle with respect to the bracket body, and the restricting member is held. By interposing the handrail holding member and the concave member at a predetermined position between the handrail holding member and the concave member, a force in a direction in which the handrail holding member and the concave member are relatively close to each other can be applied to one of the handrail holding member and the concave member, as a result. The handrail holding member and the concave member can be connected in a fixed state. As a result, as in the conventional case, the work of tightening the fastening nut to the fastening bolt penetrating the handrail holding member and the concave member with the handrail holding member adjusted to a predetermined angle with respect to the bracket body is performed. It can be made unnecessary and the handrail bracket can be easily assembled.

In the handrail bracket, it is preferable that the regulating member is provided with a regulating main body portion interposed between the retaining member and the concave member at positions on both sides in the radial direction of the shaft member, respectively.

According to this configuration, a force in a direction in which the handrail holding member and the concave member are relatively close to each other can be easily and surely applied to one of the handrail holding member and the concave member by the regulating member.

In the handrail bracket, the restricting member is continuously provided on the restricting main body portion and is formed so as to gradually become thinner from the restricting main body portion, and when the first and second brackets are combined. It is preferable to further include a regulation main body guide portion that helps the regulation main body portion to intervene between the retaining member and the concave surface member.

According to this configuration, the regulation main body guide portion can easily guide the regulation main body portion to a predetermined position where a force in a direction in which the handrail holding member and the concave member can relatively approach can be applied, and workability is improved.

In the handrail bracket, the connecting member further includes an elastic member that urges one of the handrail holding member and the concave member so that the handrail holding member and the concave member are relatively close to each other, and the pull-out member is provided. The retaining member includes a first retaining member arranged outside the handrail holding member side in the longitudinal direction of the shaft member and a second retaining member arranged outside the concave member side in the longitudinal direction. It is preferable that the elastic member is disposed between the restricting member and the second retaining member, and at least one of the restricting member and the concave member.

According to this configuration, the elastic force of the elastic member increases after the restricting member is completely interposed while the handrail holding member is appropriately slidable with respect to the concave member by the elastic force of the elastic member. The concave member can be further urged in a direction approaching the handrail holding member, and the handrail holding member and the concave member can be securely fixed.

In the handrail bracket, the coupling member includes a coupling bolt having a shaft portion having a male screw portion and a head portion, and a nut screwed to the male screw portion of the shaft portion, and the shaft member is the shaft member. The shaft portion of the coupling bolt may be formed, and the retaining member may be composed of the head of the coupling bolt and the nut.

According to this configuration, the conventional bolt for fastening and the nut for fastening can be used as they are, and can be made easy to use.

In the handrail bracket, either one of the first bracket portion and the second bracket portion is said to be between the retaining member and the concave member when the first and second bracket portions are combined. It is preferable to include a regulating member pressing portion that presses the regulating member so that the regulating member intervenes.

According to this configuration, when the first bracket portion and the second bracket portion are combined, the regulating member pressing portion naturally presses the regulating member to a predetermined position. Therefore, it is possible to eliminate the work of pressing the regulating member to a predetermined position separately from the work of combining the first bracket portion and the second bracket portion, and it is possible to facilitate the work of assembling the handrail bracket.

It is preferable that the handrail bracket is further provided with a rotation blocking portion that prevents the restricting member from rotating with respect to the shaft member.

According to this configuration, the rotation blocking portion can prevent the restricting member from rotating with respect to the shaft member. For example, when the first bracket portion and the second bracket portion are combined, the first bracket portion and the second bracket portion are combined. The regulating member can be reliably pressed into a predetermined position on either one of the above.

In the handrail bracket, the shaft member is provided with a square columnar portion having a quadrangular cross section, the restricting member is provided with an insertion portion through which the square columnar portion is non-rotatably inserted, and the rotation blocking portion is the shaft. It may be composed of the square columnar portion of the member and the insertion portion of the restricting member.

According to this, the rotation blocking portion can be easily formed.

In this embodiment, the elastic member 53 is composed of a spring washer, and is formed so as to be able to store an elastic force that tends to return to its original state when compressed in the thickness direction (axial direction). The elastic member 53 is inserted into the shaft portion 512 of the coupling bolt 51 inserted through the bolt insertion hole 43 of the concave member 4. The elastic member 53 is not limited to a form composed of a spring washer, and may be any as long as it can store an elastic force that tends to return to its original state when compressed in the thickness direction (axial direction). For example, it may be composed of a wave washer or a ring made of synthetic rubber, and can be changed as appropriate.

The washer 54 specifically includes the first to fifth washers 54a to 54e. The first washer 54a is a ring-shaped one having a spherical surface on one side, and is arranged so as to abut the head portion 511 of the coupling bolt 51 and the inner peripheral surface of the handrail holding member 3 in the handrail storage portion 331. ing.

The fifth washer 54e has a ring plate shape, and is arranged between the regulating member 6 and the nut 52 so as to come into contact with the regulating member 6 and the nut 52.

Next, the regulating member 6 will be described. As shown in FIG. 5, the restricting member 6 is made of a plate-like body in this embodiment, and the handrail holding member 6 exerts a force in a direction in which the handrail holding member 3 approaches the concave member 4 via a coupling bolt 51. The regulation main body 61 to be applied to 3, the regulation main body guide 62 for guiding the regulation main body 61 to a predetermined position where a force in the approaching direction can be applied, and the columnar portion 514b of the shaft portion 512 of the coupling bolt 51 are inserted. It is provided with a long hole-shaped shaft insertion hole 63 (insertion portion) extending in the vertical direction, and a pressed portion 64 pressed by the restricting member pressing portion 223 of the second bracket portion 22.

The regulation main body 61 is formed on both sides of the shaft insertion hole 63 in the width direction and on one side in the longitudinal direction of the shaft insertion hole 63 with the shaft insertion hole 63 interposed therebetween.

The regulation main body guide portion 62 is formed on both sides of the shaft insertion hole 63 in the width direction with the shaft insertion hole 63 interposed therebetween so that the thickness gradually decreases from the regulation main body portion 61. In this embodiment, the regulation main body guide portion 62 is configured by forming an inclined surface whose thickness gradually decreases from the regulation main body portion 61 on one surface of the regulation member 6 on the nut 52 side. The regulation main body guide portion 62 is not limited to this form, and can be appropriately changed. For example, an inclined surface whose thickness is gradually reduced from that of the regulation main body portion 61 on the other surface of the regulation member 6 on the opposite side to the nut 52 side. Or may be formed by forming an inclined surface whose thickness gradually decreases from the regulation main body portion 61 on both one side and the other side of the regulation member 6.

The pressed portion 64 is formed on the upper end surface of the restricting member 6, that is, on the end surface of the restricting main body portion 61 opposite to the restricting main body guide portion 62.

In the restricting member 6 configured as described above, the shaft portion 512 of the coupling bolt 51 is inserted into the shaft insertion hole 63 and is arranged between the fourth washer 54d and the fifth washer 54e.

Then, the nut 52 is completely tightened to the root portion of the male screw portion 513. In this tightened state, for example, as shown in FIGS. 8 and 9, if the restricting member 6 is arranged so that the restricting main body guide portion 62 abuts on the fourth washer 54d and the fifth washer 54e, the elastic member 53 is provided. Although the handrail holding member 3 is pressed against the concave surface member 4 by the elastic force of the above and a sliding resistance is applied to the handrail holding member 3, an external force is manually applied to the handrail holding member 3 against the elastic force of the elastic member 53. If given, the handrail holding member 3 can be slid with respect to the concave member 4. That is, the handrail holding member 3 is temporarily fixed. Then, when the regulating member 6 is moved from the state shown in FIGS. 8 and 9 to the position shown in FIGS. 4 and 6 in which the regulating main body 61 has entered between the fourth washer 54d and the fifth washer 54e, the coupling bolt The handrail holding member 3 is pulled toward the concave member 4 side via the 51, and the handrail holding member 3 is strongly pressed against the concave member 4 via the second washer 54b, and as a result, the handrail holding member 3 is in a non-sliding state. Will be. That is, the handrail holding member 3 is in a fixed state.

Next, the operation and effect of the handrail bracket 1 will be described together with the method of using the handrail bracket 1. First, for example, the wall mounting portion 7 is mounted at a predetermined position on the wall surface 120 by a positioning bolt and a mounting bolt (not shown). Then, the first bracket portion 21 of the bracket main body 2 is assembled to the wall mounting portion 7 by a mounting bolt (not shown).

Then, as shown in FIG. 8, the concave member 4 and the handrail holding member 3 coupled by the coupling bolt 51 and the nut 52 are first temporarily fixed as shown in FIG. 9, that is, the nut 52 is the male screw portion 513. The regulation main body guide portion 62 of the regulation member 6 is brought into contact with the fourth washer 54d and the fifth washer 54e. From this state, the handrail holding member 3 is manually slid with respect to the concave member 4 against the elastic force of the elastic member 53, and the angle (direction) of the handrail holding member 3 with respect to the bracket body 2 is adjusted (for example, FIG. The handrail holding member 3 is slid with respect to the concave member 4 as shown by the alternate long and short dash line in 9.).

After that, as shown in FIG. 9, the concave member 4 in the temporarily fixed state is fixed to the first concave member fixing portion 211 of the first bracket portion 21 of the bracket main body 2. At that time, the handrail holding member 3 is maintained in a slidable state with respect to the concave member 4 by the elastic force of the elastic member 53. Therefore, by fixing the end portion 111 of the handrail 110 to the handrail holding member 3 in this state, the handrail 110 can be connected to the handrail bracket 1 while adjusting the angle of the handrail holding member 3.

Next, the second bracket portion 22 is combined with the first bracket portion 21 by the main body connecting bolt 23 (shown in FIG. 9).

When the second bracket portion 22 is aligned with the first bracket portion 21 at the time of this union, the regulating member pressing portion 223 of the second bracket portion 22 comes into contact with the pressed portion 64 of the regulating member 6, although not shown. A gap is formed between the second bracket portion 22 and the first bracket portion 21.

Then, when the main body connecting bolt 23 inserted into the bolt insertion hole 213 of the first bracket portion 21 is started to be screwed into the female screw portion 221 of the second bracket portion 22, the second bracket portion 22 becomes the first bracket portion 21. The restricting member pressing portion 223 of the second bracket portion 22 begins to press the pressed portion 64 of the regulating member 6.

When the regulating member 6 is pressed, the regulating main body 61 of the regulating member 6 enters between the fourth washer 54d and the fifth washer 54e against the elastic force of the elastic member 53. At that time, since the thickness of the regulation main body portion 61 is thicker than the thickness of the regulation main body guide portion 62, the elastic force of the elastic member 53 increases and acts to widen the distance L between the nut 52 and the concave member 4. As a result, the coupling bolt 51 receives a force in the inward direction (X direction in FIG. 6) of the bracket body 2, that is, the coupling bolt 51 moves in the X direction, and the handrail holding member 3 has a concave surface via the second washer 54b. It is pressed against the member 4. As a result, the handrail holding member 3 is in a fixed state in which it cannot slide with respect to the concave member 4. In this case, since the regulation main body guide portion 62 is formed so as to gradually become thinner than the regulation main body portion 61, the regulation main body portion 61 can easily enter between the fourth washer 54d and the fifth washer 54e. Therefore, the temporary fixed state can be easily changed to the fixed state.

As a result, when the second bracket portion 22 is combined with the first bracket portion 21, the regulation main body portion 61 of the regulation member 6 enters a predetermined position between the fourth washer 54d and the fifth washer 54e to hold the handrail. The member 3 can be fixed to the concave member 4.

As described above, according to the handrail bracket 1 of the present invention, the handrail holding member 3 is appropriately slid along the concave surface of the concave surface member 4 so that the handrail holding member 3 is adjusted to a predetermined angle with respect to the bracket main body 2. In this state, if the regulation main body portion 61 of the regulation member 6 is interposed at a predetermined position between the nut 52 and the concave member 4, the force in the direction in which the handrail holding member 3 approaches the concave member 4 (FIG. 6). The force in the X direction) can be applied to the handrail holding member 3 via the coupling bolt 51, and as a result, the handrail holding member 3 and the concave member 4 can be coupled in a fixed state. As a result, as in the conventional case, the work of tightening the fastening nut to the fastening bolt penetrating the handrail holding member and the concave member with the handrail holding member adjusted to a predetermined angle with respect to the bracket body is performed. It can be made unnecessary and the handrail bracket can be easily assembled.

Further, since the regulation main body 61 is arranged at least on both sides of the shaft insertion hole 63 (that is, the coupling bolt 51), the force in the direction in which the handrail holding member 3 approaches the concave member 4 is restricted. It can be easily and surely given by the member 6.

Further, before the regulation main body portion 61 of the regulation member 6 is arranged at a predetermined position by the elastic member 53, the handrail holding member 3 is appropriately slid with respect to the concave member 4 by the elastic force of the elastic member 53. It can be maintained, and the regulation main body portion 61 of the regulation member 6 can be arranged at a predetermined position in that state. Further, after the regulating member 6 is arranged at a predetermined position, the elastic force of the elastic member 53 increases, and the handrail holding member 3 can be urged more strongly in the direction approaching the concave member 4, so that the handrail holding member 3 and the handrail holding member 3 can be urged. The concave member 4 can be securely fixed.

Further, when the first bracket portion 21 and the second bracket portion 22 are combined, the regulating member 6 can be pressed to a predetermined position by the regulating member pressing portion 223 of the second bracket portion 22. As a result, the work of pressing the regulating member 6 to a predetermined position can be eliminated separately from the work of combining the first bracket portion 21 and the second bracket portion 22, and the assembling work can be facilitated.

In the above embodiment, the nut 52 is the second retaining member of the present invention, but the nut 52 is not limited to this embodiment and can be changed as appropriate. For example, as shown in FIGS. 10 and 11, the second retaining member of the present invention may be composed of a push nut 520 which is a locking member locked to the male screw portion 513 of the coupling bolt 51. Further, when the second retaining member is composed of such a locking member such as a push nut 520, although not shown, the shaft member of the present invention is a male screw portion and a head instead of the coupling bolt 51. A shaft member having no portion may be used, and the first retaining member may be made of the same push nut 520 as the push nut 520.

Further, in the above embodiment, the restricting member 6 is rotatable with respect to the coupling bolt 51 as the shaft member, but the present invention is not limited to this embodiment and can be appropriately changed to rotate the restricting member 6 with respect to the shaft member. A rotation blocking portion that blocks movement may be provided. For example, the columnar portion 514 of the coupling bolt 51 is formed by forming the entire columnar portion 514 of the coupling bolt 51 as a shaft member from a rotatable and insertable square columnar portion 514a in the shaft insertion hole 63 of the regulating member 6. And the shaft insertion hole 63 of the regulating member 6 may form a rotation blocking portion, or the bracket body 2 may be provided with a rotation blocking portion that blocks the rotation of the regulating member 6 with respect to the shaft member. By providing a rotation blocking portion that prevents the restricting member 6 from rotating with respect to such a shaft member, the regulating member is pressed by the second bracket portion 22 when the second bracket portion 22 is combined with the first bracket portion 21. The portion 223 can reliably press the pressed portion 64 of the regulating member 6.

Further, in the above embodiment, the elastic member 53 is arranged between the regulating member 6 and the concave member 4, but the elastic member 53 is not limited to this embodiment, and the elastic member 53 includes the regulating member 6 and the nut 52 (the first). 2 It may be disposed between the retaining member), or may be disposed between the regulating member 6 and the nut 52 and between the regulating member 6 and the concave member 4, and may be appropriately changed. Further, it may be in a form in which the elastic member 53 is not provided.

Further, in the above embodiment, the nut 52 is screwed to the male screw portion 513 provided at the tip portion of the shaft portion 512 of the coupling bolt 51, and the nut 52 is screwed to the root portion of the male screw portion 513. Therefore, the distance L between the nut 52 and the concave member 4 is managed to some extent. Therefore, the fixing strength of the handrail holding member 3 and the concave member 4 in the fixed state is kept substantially constant. However, this fixing strength may be more adjustable. That is, for example, a male screw portion 513 is provided on the entire shaft portion 512 of the coupling bolt 51 so that the screwing position of the nut 52 in the axial direction of the male screw portion 513 can be changed in a wider range, that is, the nut 52 and the concave member 4 The interval L with and may be changed. According to this configuration, the degree of freedom of the fixing strength of the handrail holding member 3 and the concave member 4 in the fixed state is improved, and it becomes possible to provide a more practical and easy-to-use handrail bracket 1.

Further, in the above embodiment, the regulating member 6 is composed of a body separate from the second bracket portion 22, but for example, the regulating member 6 and the second bracket portion 22 may be connected to each other. That is, the regulating member 6 and the regulating member pressing portion 223 of the second bracket portion 22 are integrally molded, and the regulating member 6 receives the coupling bolt 51 as the first and second bracket portions 21 and 22 are combined. It may be formed in an inverted U shape having a groove portion capable of forming an inverted U shape.

Further, in the above embodiment, the bracket main body 2 is composed of a straight cylindrical body, but the bracket body 2 is not limited to this embodiment, and for example, as shown in FIG. 12, the handrail bracket 200 used for the corner portion is not limited to this form. The bracket body 202 may have a curved shape.
