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.)

JP 2008-308904 A (paragraph 0010, FIGS. 1C to 1D, 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. It is characterized by having a fixing means for fixing the two left and right support arms to each other.
According to the present invention, the strength for supporting the load applied to the handrail can be increased by disposing the pair of left and right two support arms at positions separated from each other. For example, as shown in FIG. 6, 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 the figure (a) in which the two support arms are arranged at a distance w and bear the load F, the surface of strength and rigidity is compared to the case of the figure (b) not separated. It is clear that it is superior.

  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.

A spacer that can be interposed and fixed between a pair of left and right support arms can be used as the fixing means.
In this case, since the pair of left and right support arms can be positioned to the left and right by the width of the spacer located between the support arms, compared to the case where the pair of left and right support arms are not separated. The strength to support the load applied to the handrail can be increased.

For the fixing means, a detachable plate capable of fixing a seat plate provided at each of the base ends of a pair of left and right support arms can be used.
In this case, if the seat plate provided at the base end of each of the pair of left and right support arms is fixed to one detachable plate, the pair of left and right support arms are fixed to be separated from each other to the left and right. Therefore, the strength for supporting the load applied to the handrail can be increased as compared with the case where the pair of left and right support arms are not separated. In addition, since a pair of left and right support arms can be fixed to the left and right by using only one detachable plate, the workability is good and the mechanism for supporting the handrail is simple and inexpensive. it can.
The detachable plate is, for example, a plate-like material indicated by reference numeral 5 in FIGS. 2, 3, and 5, and is used to fix a handrail bracket to which a handrail is attached by being attached to a wall or a headboard. Is.

A fixing seat that is formed on a cover that covers at least a pair of left and right support arms and can be interposed between the two support arms can be used as the fixing means.
In this case, since the pair of left and right two support arms are covered with the cover, the pair of left and right support arms can be separated from each other in the left and right directions. Compared with the case where there is not, the strength which supports the load applied to the handrail can be increased.

  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.

  Desirably, the handrail brackets include those that are attached to the wall and those that are directly attached to the wall and headboard. In this case, both the left and right pair of supporting arms can be arranged to be separated from each other, both in the case where the handrail bracket is attached to the wall and in the case where the handrail bracket is attached to the wall and the headboard. Compared with the case where the two support arms are not separated, the strength for supporting the load applied to the handrail can be increased.

  According to the first aspect of the present invention, the strength of supporting the load applied to the handrail can be increased by disposing the pair of left and right support arms at positions apart from each other. 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, since the pair of left and right support arms can be positioned to the left and right by the width of the spacer located between the support arms, the pair of left and right support arms are separated from each other. Compared with the case where there is not, the strength which supports the load applied to the handrail can be increased.

  According to the invention described in claim 3, if the seat plate provided at the base end of each of the pair of left and right two support arms is fixed to one detachable plate, the pair of left and right support arms is moved to the left and right. Since they can be fixed separately, the strength to support the load applied to the handrail can be increased as compared with the case where the pair of left and right support arms are not separated. In addition, since a pair of left and right support arms can be fixed to the left and right by using only one detachable plate, the workability is good and the mechanism for supporting the handrail is simple and inexpensive. it can.

  According to the fourth aspect of the present invention, since the pair of left and right support arms can be spaced apart from each other with the pair of left and right support arms 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.

  According to the fifth aspect of the present invention, the pair of left and right support arms can be arranged equally apart from each other by the two upper and lower mounting seats, so that the pair of left and right support arms are not separated. Compared to the case, the strength to support the load applied to the handrail can be increased.

  According to the invention of claim 6, even when the handrail bracket is attached to the wall, or when attached to the wall and the headboard, both of the pair of left and right support arms can be arranged apart from each other left and right. Compared with the case where the pair of left and right support arms are not separated, the strength for supporting the load applied to the handrail can be increased.

It is an example of the handrail bracket of the type attached to a wall, Comprising: Unlike the case of FIG. 3, the case where two attachment seats which can be interposed between a pair of right and left two support arms are 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. It is an example of a handrail bracket of a direct receiving type attached to a wall and a headboard, and a spacer that can be interposed and fixed between both support arms is used as a fixing means for fixing the pair of left and right support arms to each other The case is illustrated, (a) is an exploded perspective view, (b) is a sectional view showing a state in which the handrail is fixed to the handrail receiver, and shows a case where a cover that covers the handrail bracket is used. 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. 1 to 4 show a case where the fixing means for fixing a pair of left and right support arms to each other is different, which is of a type attached to a wall. Moreover, in FIG. 5, an example of the direct receiving type attached to a wall and a headboard is shown.

  FIG. 1 shows an example of a handrail bracket of the type that is attached to a wall. A fixing means for fixing a pair of left and right support arms 1 and 1 to each other is provided between the support arms 1 and 1. The case where the spacer which can be fixed is used 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.

  The reason will be described with reference to 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 left and right handrail receivers 1a, 1a are compared to the case of FIG. 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.

  FIG. 1A is an exploded perspective view thereof. As shown in FIG. 1A, a fixing means for fixing a pair of left and right support arms 1 and 1 to each other is provided between the support arms 1 and 1. Two spacers 2 and 2 that can be mounted and fixed are used. The two upper and lower spacers 2 and 2 are fastened to the pair of left and right two support arms 1 and 1 with screws 2a and 2a. In a state where 1 is separated by the width of the spacer 2, that is, a pair of left and right two support arms 1, 1 can be fixed to each other with a predetermined separation 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.

  The reason will be described in detail with reference to FIG. For example, as shown in the figure, it is assumed that a load F is applied to the handrail C at a position where the pair of left and right support arms 1, 1 and 1 ', 1' are separated from the center position by L. 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 the same load F is applied to the handrail C, the pair of left and right two support arms 1 and 1 are separated from each other by w in the case of the AA end face in FIG. It is harder to bend than the case of the BB end face of FIG. That is, it can be said that the former case is stronger than the latter. Accordingly, when the load F is increased, the pair of left and right support arms 1 ′ and 1 ′ are joined without being separated from each other in the case of FIG. It can be said that the strength is stronger in the case of FIG. 6A where the pair of left and right support arms 1 and 1 are separated by w.

  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.

  Instead of fastening the spacer 2 with the screw 2C, the spacer 2 may be crimped to the pair of left and right support arms 1, 1 or the spacer 2 may be welded to the pair of left and right support arms 1, 1. Also good.

  FIG. 2 shows an example of a handrail bracket of the type that is attached to a wall. The fixing means for fixing the pair of left and right two support arms 1 and 1 to each other is used as a fixing means. The case where the detachable plate 5 that can fix the seat plates 1b and 1b respectively provided at the base ends 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 the same as in the case of FIG.

  FIG. 2 (a) is an exploded perspective view showing that the screws 4 and 4 are screwed into the screw holes 5a and 5a of the detachable plate 5 through screw insertion holes 1c and 1c formed in the seat plate 1b. Thus, 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. FIG. 2 (b) is a perspective view, FIG. 2 (c) is a front view, and FIG. 2 (d) is a side view.

  Also in this case, the seat plates 1b and 1b of the pair of left and right support arms 1 and 1 are separated by an interval between the support arms 1 and 1 when the mounting plates 5 are fixed to the detachable plate 5, that is, left and right The pair of two support arms 1 and 1 can be fixed to each other with a predetermined distance between them. 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 FIG. 2, as shown in FIGS. 2A to 2C, one spacer 2 used in the case of FIG. In FIG. 2, the screw 2a is interposed and fixed between the support arms 1 and 1, thereby assisting in determining the distance between them.

  As in the case of FIG. 1, the handrail C can be fixed to the left and right handrail receivers 1a, 1a with screws (not shown), but in FIG. 2, the handrail C is shown in a omitted state. The pair of left and right support arms 1 and 1 can be fixed to a wall (not shown) by using three wall fixing screws 3 respectively inserted into the three holes 5b of the detachable plate 5. .

  FIG. 3 shows an example of a handrail bracket of the type attached to a wall, and at least a pair of left and right support arms 1 and 1 is used as a 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 the same as in the case of FIG. 1 and FIG.

  FIG. 3 (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 left and right two seat plates 1b and 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 of the covers 6 and 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.

  In the case of FIG. 3, the detachable plate 5 is used as in the case of FIG. 2, and the screws 4 and 4 are screwed through the screw insertion holes 1c and 1c formed in the seat plate 1b. 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 into the holes 5a and 5a, respectively. FIG. 3 (b) is a perspective view, FIG. 3 (c) is a front view, and FIG. 3 (d) is a side view. In addition, it is possible to fix a pair of left and right support arms 1 and 1 to a wall (not shown) by using three wall fixing screws 3 respectively inserted into three holes of the detachable plate 5. This is the same as in the case of FIG.

  As shown in FIG. 3, 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. 3, the upper cover of the upper and lower split covers 6, 6 that covers the pair of left and right support arms 1, 1, the left and right handrail receivers 1 a, 1 a, and the two 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. 4, 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. It is the same as in the case of FIG. 1, FIG. 2, and FIG.

  FIG. 4 (a) is an exploded perspective view of the pair of left and right support arms 1 and 1, two left and right handrail receivers 1a and 1a, and left and right two 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 separation 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 FIG. 4, the wall fixing screw 3 (not shown) used in FIGS. 1 to 3 is directly screwed into the wall via the upper and lower screw insertion holes 1d and 1d formed in the seat plate 1b. Thus, the seat plates 1b and 1b of the pair of left and right support arms 1 and 1 can be fixed to a wall (not shown).

  1 to 4 show a handrail bracket of a type attached to a wall, while FIG. 5 shows an example of a handrail bracket of a direct receiving type attached to a wall and a headboard. In describing this type of handrail bracket, members having substantially the same action as the handrail bracket of the type attached to the wall of FIGS. 1 to 4 will be described using the same names and the same reference numerals. I will do it.

  In this type of handrail bracket, a pair of left and right support arms 1, 1 are arranged vertically, and a handrail for fixing the handrail C to the upper ends of both vertical support arms 1, 1. The receiving plate 1a is provided with a seat plate 1b horizontally at the lower end, and the two supporting arms 1 and 1 are separated into a pair of left and right as shown in FIGS. Same as the case.

  FIG. 5 (a) is an exploded perspective view showing that the screws 4 and 4 are screwed into the screw holes 5a and 5a of the detachable plate 5 through screw insertion holes 1c and 1c formed in the seat plate 1b. Thus, 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. This state is shown in a longitudinal sectional view in FIG.

  Even in this case, the seat plates 1b and 1b of the pair of left and right support arms 1 and 1 are separated by an interval w between the support arms 1 and 1 when the mounting plates 5 are fixed to each other, 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.

  Also in the case shown in FIG. 5, as shown in FIGS. 5A and 5B, one spacer 2 used in the case of FIG. 1 is used, and at the upper end side of the pair of left and right support arms 1 and 1. A screw 2a is interposed and fixed between the support arms 1 and 1 to assist in determining a separation distance between them.
