Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a handrail bracket.
[0002]
[Prior art]
As a handrail bracket used when the handrail headboard is disposed along an installation base such as a wall surface, one described in JP-A-9-296579 has been known. In this conventional example, the handrail bracket includes a bracket body and a bracket cover that covers the bracket body. The bracket cover is composed of a plurality of bracket cover members, and each bracket cover member is fixed by locking a locking claw in a locking recess formed in the bracket body.
[0003]
[Problems to be solved by the invention]
However, the conventional example described above has the following drawbacks. That is, since each bracket cover member is fixed with respect to the bracket body, in order to prevent a gap between the bracket covers when the bracket cover member is mounted on the bracket body, it is necessary to lock the bracket cover member. It is necessary to accurately manage the dimensions of the claw and the locking recess, that is, the dimensions of both the bracket cover and the bracket main body, resulting in poor manufacturing efficiency.
[0004]
Further, the locking recess for preventing the bracket cover from falling off needs to be recessed in a direction orthogonal to the mounting direction of the bracket cover member. For this reason, for example, when the bracket body is injection-molded using a mold whose mounting direction of the bracket cover member is the mold splitting direction, in order to form a locking recess that is undercut in the mold splitting direction. It becomes necessary to use a slide core or the like, which complicates the structure of the mold and increases the manufacturing cost.
[0005]
Further, since the locking recess is disposed on the surface portion of the bracket body ignoring the design element, for example, it cannot be used in a state where the bracket cover is not attached.
[0006]
In addition, considering the arrangement of the locking claws and the locking recesses, a bracket cover member that matches the bracket body is set in advance, so there are many types of bracket covers depending on the type of bracket body. As a result, product management becomes troublesome.
[0007]
Further, in the handrail bracket, it is necessary to repair the loosening of the fixing nut due to long-term use by inspection work. However, when the fixing nut is covered with the bracket cover, the bracket cover must be removed. However, in the conventional locking structure that releases the locking by deforming the bracket cover by external force, there is a risk of falling off due to external force during use, but if the locking structure is strengthened, it becomes difficult to remove, There is a problem that the bracket cover is damaged.
[0008]
The present invention has been made to eliminate the above drawbacks, and an object thereof is to provide a handrail bracket that is easy to manufacture and inexpensive.
[0009]
[Means for Solving the Problems]
According to the present invention, the object is
A bracket body 3 for fixing the handrail cap 1 to an installation base 2 such as a wall surface;
A bracket cover 4 that covers the bracket body 3 so as to surround it,
The bracket cover 4 is formed by a plurality of divided covers 6 that can be connected to each other and can be positioned by contacting the surface irregularities 5 of the bracket body 3.
The split covers 6 have locking hooks 7 projecting from one side edge connected to the other side edge toward the side facing the bracket body 3 with respect to the one side edge. A tongue piece 9 is formed in a cantilever shape from the other side edge to be connected to the bracket body 3 side of the locking hook 7 and is elastically deformable toward the side facing the bracket body 3. One and the other connection that can be inserted into the through hole 3c formed in the cap support piece 3b of the bracket body 3 and outside the side edge of the cap support piece 3b. One auxiliary connecting rod 6b formed on the straight rod-shaped connecting auxiliary rod 6b is fitted and positioned on the other connecting auxiliary rod 6b having a hollow cylindrical shape ,
And the small hole 14 which faces the said tongue piece 9 was opened in the connection part of the said division | segmentation cover 6,
A handrail bracket in which the tongue piece 9 is pressed from the small hole 14 toward the side facing the bracket main body 3 with a pin-shaped tool so that the engagement hole 8 and the engagement hook 7 can be disengaged. Achieved by providing.
[0010]
A bracket cover 4 that covers the bracket body 3 by surrounding the bracket body 3 is configured by connecting a plurality of divided covers 6. The divided covers 6 can be connected to each other, and can cover the bracket body 3 while maintaining, for example, a cylindrical shape without being locked to the bracket body 3. The bracket-shaped bracket cover 4 is positioned by coming into contact with the surface irregularities 5 of the bracket body 3, thereby preventing displacement with respect to the bracket body 3.
[0011]
Therefore, in the present invention, only the dimensional accuracy of the connecting portion of the divided cover 6 and, more precisely, the connecting portion of the divided cover 6 is managed, and the gap in the connecting portion when mounted on the bracket body 3 or the joint width is not uniform. Occurrence can be completely prevented.
[0012]
In addition, it is not necessary to form a locking recess for locking the divided cover 6 in the bracket body 3, and the positioning of the divided cover 6 is performed using the unevenness on the surface of the bracket body 3, In addition to simplifying the molding die, it can be formed into a desired design, so that it can be used without using the bracket cover 4 according to the customer's preference.
[0013]
Further, since the plurality of divided covers 6 can be connected to each other without the bracket main body 3, they can be covered with different bracket main bodies 3, so that parts can be shared.
[0014]
Further, the divided covers 6 are connected to each other by engaging a locking hook 7 protruding from one side toward the side facing the bracket body 3 with the other locking hole 8, and the locking hole 8 is connected to the bracket. The tongue 9 is formed in a cantilever shape that can be elastically deformed toward the side facing the main body 3 .
[0015]
In this configuration, when the split cover 6 is bent inward with the locking hook 7 of one split cover 6 locked in the locking hole 8 of the other split cover 6, it is pushed by the locking hook 7. The elastically deformable tongue piece 9 also bends inward following the movement of the locking hook 7. As a result, even if a pressing force is applied to the bracket cover 4 inadvertently, the connection between the divided covers 6 is not inadvertently released, and the bracket cover 4 can be reliably prevented from falling off.
[0016]
In the invention according to claim 2 , the bracket cover 4 is formed by connecting divided covers 6 having the same shape. The divided cover 6 includes a locking hook 7 on one of the edges corresponding to the other divided cover 6 and a locking hole 8 on the opposite side. When the divided cover 6 is disposed so as to surround the bracket body 3, the locking hook The edge on the side where 7 is formed faces the edge on the side where the locking hole 8 is formed.
[0017]
Therefore, according to the present invention, since the bracket cover 4 can be configured only by preparing one type of divided cover 6, the number of manufacturing and management man-hours can be reduced.
[0018]
Further, the connecting portion of the divided cover 6, divided by the small hole 14 facing the tongue 9 is opened, the pin-like tool from the small hole 14 to deflect the side facing the tongue 9 in the bracket body 3 The connection of the cover 6 can be released.
[0019]
Therefore, in this configuration, even if the split cover 6 is deformed by an external force , the locking hook 7 and the tongue piece 9 follow and deform in the engaged state, and do not fall off carelessly. Since, for example, a pin-shaped tool is inserted from the small hole 14 to deform only the tongue piece 9 and the engagement with the locking hook 7 can be easily released, the usability, especially the maintainability, is improved.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a handrail device including a handrail bracket according to the present invention. The handrail device is formed by connecting a handrail headboard 1 (horizontal headboard 1a) arranged in a horizontal direction and a handrail headboard 1 (vertical headboard 1b) arranged in a vertical direction by a corner joint 10. In this embodiment, as shown in FIG. 2 (b), the handrail head 1 is formed by fitting a covering material 1d made of a synthetic resin over almost the entire length of the metal base 1c. It is fixed to the wall surface (installation base 2) through the bracket 12 for use.
[0021]
The Yokobanagi bracket 12 is fixed to the wall surface 2 and is fitted and fixed to the groove portion 1e of the metal base 1c so as to cover the Yokobanagi bracket main body 12a for supporting the handrail coping 1 from below and the Yokobanagi bracket main body 12a. It consists of a bolt for fixing the fixing piece 12c to the wall surface 2 and a bracket cover 12b for the horizontal headwood which prevents the nut 12d from being exposed.
[0022]
On the other hand, the vertical headboard 1b is fixed to the wall surface 2 by the handrail bracket according to the present invention. The handrail bracket includes a bracket body 3 that supports an intermediate portion of the vertical headboard 1b, and a bracket cover 4 that covers the bracket body 3 so as to surround it. As shown in FIG. 2, the bracket body 3 has a fixed piece 3a to the wall surface 2 and a cap support piece 3b standing upright from the center of the fixed piece 3a. The vertical headboard 1b is supported by fitting and fixing to the groove 1e of the metal base 1c. As shown in FIG. 1, the bracket body 3 has a symmetrical shape with respect to the longitudinal center line of the vertical headboard 1b, and the bracket body 3 is hidden behind the vertical handrail when the handrail is viewed from the front after installation. Configured as follows. In FIG. 2, reference numeral 2a denotes an anchor bolt embedded in the wall surface 2, and 2b denotes a fixing nut.
[0023]
As shown in FIG. 3, the bracket cover 4 is formed by connecting a pair of divided covers 6, 6 having the same shape at a dividing surface that coincides with the longitudinal center line of the vertical headboard 1 b. As shown in FIG. 5, the split cover 6 is formed in a half hollow cylindrical circular cone shape whose bottom edge coincides with the outer periphery of the fixing piece 3 a of the bracket body 3, and the fixing piece 3 a of the bracket body 3 is formed on the inner wall surface 2. A pair of positioning pieces 6a, 6a capable of sandwiching the surface uneven portion 5 formed by the concave portion 5a provided on the side wall and the upper edge 5b of the fixing piece 3a, and a through-hole provided in the head support 3b of the bracket body 3 Two auxiliary connecting rods 6b and 6b that can pass through the inside of 3c and the outer side edge of the head support piece 3b are provided. One of the auxiliary connecting rods 6b is formed in a straight rod shape, and the other is formed in a hollow cylindrical shape into which the straight auxiliary rod connecting rod 6b can be inserted.
[0024]
Therefore, in this embodiment, when the two divided covers 6 face each other so as to wrap the bracket body 3, the positioning piece 6a sandwiches the surface irregularities 5 of the bracket body 3 as shown in FIG. The one of the straight rod-shaped connection auxiliary rods 6b inserted through the through hole 3c of the bracket body 3 is fitted and positioned to the other hollow cylindrical connection auxiliary rod 6b. In this embodiment, the divided cover 6 is positioned with a recess 5a and a through-hole 3c provided in the bracket body 3 mainly from the viewpoint of design when the bracket cover 4 is used without being mounted, as will be described later. Although the case where it uses as a part is shown, as a positioning part, the other unevenness | corrugations formed in the bracket main body 3, for example, the step part formed in the upper edge 5b of the fixed piece 3a can also be utilized.
[0025]
In order to connect the divided covers 6, 6 positioned as described above, a locking hook 7 protruding inwardly on one side edge (dividing line) of the divided cover 6 is locked on the other side. A hole 8 is provided. As shown in FIG. 5, the locking hole 8 is formed in the tongue piece 9 branched from the inner wall of the side edge, and a hook insertion gap 6d is formed between the tongue piece 9 and the outer shell 6c.
[0026]
The locking hook 7 and the locking hole 8 are formed at the same height from the bottom edge, and when the two divided covers 6 are opposed to each other, one locking hook 7 corresponds to the other locking hole 8. To do. When the split surfaces of the two split covers 6 are pressed in this state, the tongue piece 9 is once elastically deformed by the locking hook 7 that has entered the hook insertion gap 6d, and then returns to the original position, and the locking hook 7 is engaged. Lock to the stop hole 8. As a result, as shown in FIG. 4B, the locking hook 7 is locked to the locking hole 8 at both side edges (divided surfaces), and separation in the connecting direction is prohibited. Further, even when a load in the direction of the arrow in FIG. 4B is applied to the divided cover 6 in this state, both the tongue piece 9 and the locking hook 7 are elastically deformed in the load direction, so that the locking is released. There is no.
[0027]
Furthermore, this embodiment includes a connection release means for the divided cover 6. As described above, once the divided covers 6 are connected to each other, they cannot be separated depending on the load of external force applied to the divided covers 6. The connection release means is provided so as to be able to release the connection between the divided covers 6 when necessary, such as inspection work or replacement of the divided covers 6, as shown in FIG. 5 (a). It is formed by providing a notch 6e at the edge of the cover 6. As shown in FIGS. 6A and 6B, the notch 6 e forms a small hole 14 that opens in the joint portion 4 a formed in the connecting portion of the divided cover 6 in a state where the divided covers 6 are connected to each other. The small hole 14 is formed at a position facing the tongue piece 9, and as shown in FIG. 6C, only the tongue piece 9 can be pressed by inserting a pin-shaped tool 15.
[0028]
Therefore, in this embodiment, when the tool 15 is inserted from the small hole 14 and the tongue piece 9 is pressed, the locking hole 8 formed in the tongue piece 9 is also retracted inward, and the locking hook 7 and the locking hole 8 are moved. After that, when the divided cover 6 is slid in the separating direction, the divided cover 6 can be easily removed.
[0029]
Therefore, according to this embodiment, after fixing the vertical headboard 1b with the handrail bracket, the bracket body 3 can be covered by simply connecting the pair of divided covers 6 and 6 so as to wrap the bracket body 3. The bracket cover 4 once in a connected state is not inadvertently separated. Moreover, the division | segmentation cover 6 can be isolate | separated whenever necessary, such as inspection work.
[0030]
Furthermore, since an unnecessary connecting portion for fixing the divided cover 6 is not formed on the bracket body 3, there is no sense of design discomfort even if it is used in an exposed state by applying an appropriate surface treatment. For this reason, since the specification which uses the bracket cover 4 shown in FIG. 3 and the specification which is not used shown in FIG. 2 can be properly used according to a user's liking, a product type can be increased substantially.
[0031]
In the above description, the bracket cover 4 covers the entire bracket body 3, but as shown in FIG. 7, in order to adjust the installation height from the installation base 2 of the vertical headboard 1a, When using the bracket main body 3 which has the base part 3d, it can also be comprised so that the part may be covered.
[0032]
【The invention's effect】
As is apparent from the above description, according to the present invention, even when the connecting portion of the divided cover is brought into close contact or the joint is formed with an appropriate interval between the connecting portions, the hook for holding the divided cover is used. By simply managing the positional relationship between the engagement holes and the locking holes, the divided covers can be securely brought into contact with each other or the joint width can be made uniform, so that the manufacturing efficiency is improved.
[0033]
In addition, it is not necessary to form a locking part to the locking hook in the bracket body, and since the bracket body can be finished in a shape that takes into account only design requirements, it is not unsightly without mounting a bracket cover. Product variation can be increased.
