Description

  The present invention relates to a handrail bracket for attaching a handrail, and more specifically, a handrail receiver for fixing a handrail to a distal end, a support arm having a seat plate at a base end, and a pair of left and right separated forms About what

  A handrail bracket for attaching a handrail, in which a pair of left and right support arms are spaced apart by a predetermined distance (for example, see Patent Document 1), and the support arms are joined from the middle (For example, refer to Patent Document 2), and a pair of left and right support arms joined together and fixed by welding or the like (for example, refer to Patent Document 3) have been proposed.

Microfilm of actual application No. 58-000805 (No. 59-106944) (request for registration of utility model, FIG. 2, FIG. 3 etc.)

Japanese Patent Laying-Open No. 2008-308904 (paragraph 0010, FIGS. 1 (c) to (d), etc.)

JP 2009-019434 A (Claims, FIG. 2 etc.)

  However, in both of Patent Documents 1 and 2, the base end portions of the pair of left and right support arms are integrated with one seat plate by welding or the like, and the pair of left and right support arms are not separated. Moreover, since the fastening to the wall is located between the pair of left and right support arms, it is not preferable in terms of strength. If the fastening pitch is increased to increase the strength, the handrail bracket is increased in size, which is disadvantageous in terms of design and cost.

  On the other hand, the one shown in Patent Document 3 is disadvantageous in terms of strength because the pair of left and right support arms are in close contact.

  When the handrail is supported by such a handrail bracket, it seems that the load applied to the handrail cannot be sufficiently supported. This is because the force for supporting the load applied to the handrail becomes weaker as much as the distance between the pair of left and right support arms cannot be increased too much. The greater the distance between the pair of left and right support arms, the greater the force that supports the load on the handrail.

The present invention has been developed for the purpose of eliminating the above-described drawbacks, and has a handrail support for fixing a handrail at the distal end, and a support arm having a base plate at the base end. A pair of left and right support arms that are separated from each other and formed on a cover that covers at least the pair of left and right support arms. It is characterized by comprising fixing means comprising a mounting seat that can be interposed between the fixing seats .
According to the present invention, since the pair of left and right two support arms are covered with the cover, the pair of left and right pair of support arms can be spaced apart from each other. Compared with the case where it is not , the strength which supports the load applied to the handrail can be increased. For example, as shown in FIG. 3 , assuming that a load F is applied to the handrail at a position where the pair of left and right two support arms are separated from the center position by L, the pair of left and right supporting the handrail In the case of Fig. 7 (a) where the supporting arms are arranged at intervals w and bear the load F, the strength and rigidity are superior to the case of Fig. 9 (b) where they are not separated. It is clear that

  In addition, according to the present invention, since the two support arms are separated into a pair of left and right, the handrail attached to the handrail receiver is not only stable, but also the workability of attaching the handrail to the handrail receiver is good.

  It is desirable that two upper and lower mounting seats that can be interposed between a pair of left and right support arms are provided. In this case, a pair of left and right two support arms can be equally spaced apart from the top and bottom with two upper and lower mounting seats, so compared to the case where the pair of left and right two support arms are not separated, The strength to support the load applied to the handrail can be increased.

According to the first aspect of the present invention, since the pair of left and right support arms can be separated from each other in a state where the pair of left and right support arms are covered with the cover, Compared with the case where the supporting arm is not separated, the strength for supporting the load applied to the handrail can be increased. In addition, since the two support arms are separated into a pair of left and right, the handrail attached to the handrail receiver is not only stabilized, but also the workability of attaching the handrail to the handrail receiver is good.

According to the second aspect of the present invention, it is possible you to place a pair of left and right two support arms up and down both away to the left and right equally in two upper and lower mounting seat, a pair of left and right two support arms away Compared with the case where there is not, the strength which supports the load applied to the handrail can be increased.

It is an example of a handrail bracket of the type that is attached to a wall, and is formed on a fixing means for fixing a pair of left and right support arms to each other, and a cover that covers at least the pair of left and right support arms. This is an example in which a mounting seat that can be interposed between two support arms is used, (a) is an exploded perspective view, and (b) is a perspective view showing a state in which at least a pair of left and right support arms are covered with a cover. (C) is a front view thereof, (d) is a side view thereof, (e) is a handrail receiver when the handrail receiver provided at the tip of the pair of left and right support arms is covered with a part of the cover. It is sectional drawing which shows that a handrail can be stably supported by a part of cover located outside. It is an example of the handrail bracket of the type attached to a wall, Comprising: Unlike the case of FIG. 1 , the case where the two mounting seats which can be interposed between two left-right paired support arms is provided is illustrated. (A) is an exploded perspective view, (b) is a perspective view showing a state where at least two pairs of left and right support arms are covered with a cover, (c) is a front view thereof, and (d) is a side view thereof. It is. When the load F is applied to the handrail at a position where the pair of left and right two support arms are separated from the center position by L, the pair of left and right support arms supporting the handrail are arranged at an interval w. In the case of Fig. (A), compared to the case of Fig. (B) that is not separated, the handrail attached to the handrail receiver is not only stable, but also the handrail mounting to the handrail receiver is better. It is a principle diagram for explaining that it is excellent in terms of strength and rigidity.

An example of a handrail bracket according to the present invention will be described in detail with reference to the drawings. The handrail bracket is of a type that can be attached to the wall, or a type of direct receiving type that can be attached to the wall and headboard. FIGS. 1 and 2 are of a type attached to a wall, and are formed on a fixing means for fixing a pair of left and right support arms to each other and on a cover covering at least the pair of left and right support arms. have been, that shows an example case where a mounting seat which can be interposed between the two support arms. In addition, about the handrail bracket of the direct receiving type attached to a wall and a headboard , illustration is abbreviate | omitted .

FIG. 1 shows an example of a handrail bracket of a type that is attached to a wall, and at least a pair of left and right support arms 1 and 1 are used as fixing means for fixing the pair of left and right support arms 1 and 1 to each other. The case where the attachment seat 6a which is formed in the cover 6 which covers and can be interposed between the two support arms 1 and 1 is illustrated. A pair of left and right two support arms 1 and 1 are provided with a handrail receiver 1a for fixing the handrail C, and a base plate is provided with a seat plate 1b. It is a separate form. If it is set as such a form, the handrail C attached to the handrail receivers 1a and 1a will not only become stable, but the installation workability of the handrail C to the handrail receivers 1a and 1a is also good.

It will be described with reference to the reason in FIG. As shown in FIG. 5A, when a pair of left and right support arms 1 and 1 supporting the handrail C are arranged at a distance w, the width a ′ of the two left and right handrail receivers 1a and 1a. Is larger by w than in the case of the width b ′ in FIG. Therefore, the handrail C attached to the left and right handrail receivers 1a and 1a having a width larger by w is stabilized. Further, when attaching the handrail C to the left and right handrail receivers 1a, 1a, the handrail C is fastened with screws under the condition that the handrail C is temporarily placed on the handrail receivers 1a, 1a. In the case of the same figure (a) where the width of 1a, 1a is larger by w, the two left and right handrail receivers 1a, 1a are compared to the case of the same figure (b) where the supporting arms 1 ', 1' are not separated. Since the possibility that the handrail C falls from the bottom is low, it can be said that the installation workability of the handrail C to the handrail receivers 1a and 1a is also good.

Then assume, for example, as shown in the figure, a pair of right and left two support arms 1, 1 1 ', 1' in the away from the center position by L position, where the load F is loaded to the handrail C To do. In this case, in the case of FIG. 5A, a pair of left and right support arms 1 and 1 supporting the handrail C are arranged at an interval w. On the other hand, in the case of FIG. 5B, the pair of left and right support arms 1 ′ and 1 ′ are joined without being separated. In comparison with this case, the pair of left and right two support arms 1 and 1 are arranged at a distance w and the two support arms 1 and 1 are separated from each other and bear the load F in the case of FIG. It is clear that this is superior in terms of strength and rigidity compared to the case of FIG.

This is because, when loaded with the same load F railings C, towards the case of the A-A end face of Figure 3 a pair of left and right two support arms 1,1 are separated by w (a) is a pair of left and right 2 one of the support arms 1 ', 1' is less likely to bend than that of B-B end surface shown in FIG. 3 (b) are joined without away. That is, it can be said that the former case is stronger than the latter. Accordingly, in a case where performed to raise the value of the load F, a pair of left and right two support arms 1 ', 1' towards the case of FIG. Are joined without away 3 (b), the plastic deformation or fracture it is easy, towards the case of FIG. 3 that a pair of left and right two support arms 1,1 are separated by w (a) is, it can be said that strength is high.

  The handrail C can be fixed to the left and right handrail receivers 1a and 1a with screws (not shown), and is fixed to two walls respectively inserted into two holes formed in the both seat plates 1b and 1b. The pair of left and right support arms 1 and 1 can be fixed to a wall (not shown) by using the screw 3 for use.

As shown in FIG. 1 (a) , a pair of left and right covers 6, 6 covering a pair of left and right support arms 1, 1 and two left and right handrail receivers 1a, 1a and two left and right seat plates 1b, 1b. A mounting seat 6 a that can be interposed between the two support arms 1 and 1 is formed on the upper cover 6.

  Also in this case, at least a pair of left and right two support arms 1 and 1 are covered with two upper and lower covers 6 and 6, and the mounting seat 6 a is interposed between the two support arms 1 and 1. By inserting and fastening the screw 6b into the screw insertion hole 6a 'formed in the mounting seat 6a, the pair of left and right support arms 1, 1 are separated by the width of the mounting seat 6a, that is, The pair of left and right support arms 1 and 1 can be fixed to each other with a predetermined distance. In this way, by arranging the pair of left and right two support arms 1 and 1 at positions separated from each other, the strength for supporting the load applied to the handrail C can be increased.

As shown in FIG. 1, a detachable plate 5 is used for the handrail bracket, and screws 4 and 4 are screwed through holes 1c and 1c formed in the seat plate 1b through screw holes 5a, The seat plates 1b and 1b of the pair of left and right support arms 1 and 1 can be fixed to the single detachable plate 5 by being screwed to 5a. The state in a perspective view in FIG. 1 (b), a front view in FIG. (C), respectively in side view in FIG. (D). Note that using three screws 3 for the wall fixing of the respectively inserted into the three holes of the detachable plate 5, Ru can be fixed to a wall (not shown) a pair of left and right two support arms 1, 1 .

As shown in FIG. 1 , when at least a pair of left and right support arms 1 and 1 are covered with upper and lower split covers 6 and 6, when handrail C is received by handrail receiver 1a, FIG. As shown in FIG. 3, since the part 6c of the cover 6 is located outside the handrail receiver 1a, the handrail C can be stably supported by the part 6c of the cover 6 located outside, and the handrail C can be supported at the time of fastening. Easy to support. For example, as shown in FIG. 5 (e), the handrail C is supported by the portion including the part 6c of the cover 6 as compared with the width x that can receive the handrail C when the handrail C is supported only by the handrail receiver 1a. In this case, as shown in FIG. X, the handrail C can be supported with a width wider than at least the width x.

In FIG. 1 , the upper cover of the upper and lower split covers 6, 6 covering the pair of left and right support arms 1, 1, the left and right handrail receivers 1 a, 1 a and the left and right seat plates 1 b, 1 b. 6, a mounting seat 6a that can be interposed between the two support arms 1 and 1 is formed, whereas in FIG. 2 , it can be fixed between a pair of left and right support arms 1 and 1. The case where the two mounting seats 6a are provided up and down is illustrated. A pair of left and right two support arms 1 and 1 are provided with a handrail receiver 1a for fixing the handrail C, and a base plate is provided with a seat plate 1b. that there as a separate form One, Figure 1, is the same both FIG.

FIG. 2 (a) is an exploded perspective view showing a pair of left and right support arms 1 and 1, two left and right handrail receivers 1a and 1a, and two left and right seat plates 1b and 1b. Two upper and lower mounting seats 6 a and 6 a that can be interposed between the two support arms 1 and 1 are formed on the upper cover 6 of the covers 6 and 6.

  Also in this case, at least the pair of left and right two support arms 1 and 1 are covered with the upper and lower split covers 6 and 6, and the upper and lower mounting seats 6 a and 6 a are interposed between the two support arms 1 and 1. And mounting the screws 6b and 6b through the screw insertion holes 6a 'and 6a' formed in the mounting seats 6a and 6a and fastening the two left and right support arms 1 and 1 to the mounting seat. The pair of left and right support arms 1 and 1 can be fixed to each other in a state where they are separated by a width of 6a, that is, in a state where a predetermined distance is provided. In this way, by arranging the pair of left and right two support arms 1 and 1 at positions separated from each other, the strength for supporting the load applied to the handrail C can be increased.

In the case of Figure 2, by screwing directly into the wall through the upper and lower two screw insertion holes 1d, 1d of the screw 3 for wall fixing using Oite (not shown) formed in the seat plate 1b in FIG. 1 The seat plates 1b and 1b of the two left and right support arms 1 and 1 can be fixed to a wall (not shown).
