Description

  The present invention relates to a handrail bracket used for installing a handrail on a top plate such as a counter or a shelf installed on furniture such as a table, a wall surface, a bay window, or the like.

  Although it is well known to install handrails on indoor walls and pillars to ensure walking assistance and walking safety, as handrails used at other installation locations, for example, on table tops The installed ones are presented in Japanese Patent Application Laid-Open No. 2005-111092 (Patent Document 1), Japanese Patent Application Laid-Open No. 2003-220103 (Patent Document 2), and the like.

  Tables and counters are used to perform tasks that are indispensable in daily life, such as eating and drinking, reading, and recently operating computers, especially because tables can be moved and installed in appropriate places in the room. It is possible and it is considered that the handrails attached to these are extremely useful in daily life and workplaces.

  However, in the invention described in Japanese Patent Application Laid-Open No. 2005-111092 (Patent Document 1), as shown in FIG. 12, the handrail 6A is erected on the upper surface 50A of the top plate 5A, It is difficult to use the top plate, which is a function, and it is not easy to use. Further, in the invention described in Japanese Patent Laid-Open No. 2003-220103 (Patent Document 2), as shown in FIG. 13, a handrail 6B is attached by a bracket 1B installed on an outer peripheral edge 51B of the top plate 5B. Although there is no particular hindrance to the use of 5B, it is difficult or difficult to install a relatively thin top plate or one using a structurally easy top plate, for example, it may cause a crack when trying to install it forcibly. However, sufficient strength cannot be obtained, and there is a problem that the mounting portion is liable to come off due to the action of a load during use.

  The problems with the conventional table with handrails as described above are all well known in the past for attaching handrails to vertical surfaces such as pillars and wall surfaces of houses as handrail brackets used when handrails are installed. This is due to the use of.

  On the other hand, Japanese Patent Application Laid-Open No. 2006-144451 (Patent Document 3 (hereinafter referred to as “Document 3”)) includes an arm portion 4C that is recessed and curved in the floor surface direction, and an arm portion 4C as shown in FIG. A fixing portion 2C provided on one end side of the top plate (counter) 5C and attached to the back surface 52C of the top plate (counter) 5C, and a support portion 3C provided on the other end side of the arm portion 4C and attached to the lower surface portion of the handrail 6C. The handrail mounting hardware provided is presented.

  In the handrail mounting hardware described in this document 3, the fixing portion 2C is installed not on the vertical surface such as the upper surface 50C or the outer peripheral edge 51C of the top plate 5C but on the back surface 52C of the top plate 5C. General problems have been improved.

However, in the handrail mounting hardware described in the above-mentioned document 3, the arm portion 4C has a round bar shape as shown in the drawing, and the fixing portion 2C has a depth substantially the same as the width (diameter) of the round bar-like arm portion 4C. Although it is suitable for integral molding by casting because of its elongated shape extending in the direction, since the arm 4C is connected at the front end of the fixing portion 2C, the load on the fixing portion 2C in use In addition, the fixing portion 2C elongated in the depth direction is fixed by screws arranged in a row in the depth direction, so that not only the load in the floor direction of the handrail 6C but also the twist in the left-right direction is prevented. However, even if it is a relatively short handrail, it has a structure that cannot be said to have sufficient fixing strength, such as requiring installation at a plurality of locations on the handrail.
On the other hand, as shown in the drawing, it is conceivable to form a mounting recess 53C that accommodates the fixing portion 2C on the back surface 52C of the top plate 5C. Therefore, it is necessary to make the mounting recess 53C in conformity with the above-mentioned dimensions.

  In order to secure the strength with the round bar-shaped arm portion, it is necessary to bend the arm portion 4C greatly downward to release the load. In this case, the arm portion 4C is seated on a chair and uses a table or the like. There is also a problem that if the arm portion 4C and the fixing portion 2C are simply made thicker, it is difficult to reduce the weight and increase the material cost.

  Next, in Japanese Patent Application Laid-Open No. 2006-116209 (Patent Document 4), as shown in FIGS. 15A and 15B, a handrail 6D that can be pulled out in the horizontal direction on the outer peripheral edge 51D of the top plate 5D is provided. An equipped table is presented, and this table has a handrail 6D formed as part of the edge of the top plate so that it can be used as needed and can be used as a top plate when not in use. Although it has the advantage that it is almost the same in terms of usability and appearance as a normal table and has no sense of incongruity, the structure of the handrail support means requires complicated construction inside the top plate 5D and is not easy to manufacture. There is a problem that it cannot be installed on an existing table by retrofitting, and further, since the handrail forms a part of the table, another handrail that is easy to use cannot be freely selected and used.

JP 2005-111092 A JP 2003-220103 A JP 2006-144451 A JP 2006-116209 A

  In the present invention, it is needless to say that the handrails are securely and securely installed along the outer peripheral edge of the top plate such as a table or a counter, and various arrangements and uses of the handrails are possible and easy to manufacture. In addition to providing a handrail bracket that is light and lightweight, the distance between the handrail and the outer periphery of the top plate can be adjusted, and in addition, when the handrail is not used, it can be attached to the back of the top plate without removing the handrail. It is an object of the present invention to provide a handrail bracket that can be stored.

  The present invention made to solve the above problems is a handrail bracket for attaching a handrail disposed along the outer peripheral edge of the top plate, and a fixing portion fixed to the back surface of the top plate; And a support part for fixing the handrail, and an arm part for connecting the fixing part and the support part, wherein the arm part is formed by a pair of side walls facing each other and an upper wall for connecting the side walls. It has a shape with a hollow cross section and an open bottom surface, and a pair of side walls forming the arm portion are respectively extended from the lower surface of the fixing portion to the lower surface of the support portion.

  According to the present invention, since the fixing portion is fixed to the back surface of the top plate, there is a problem with the original use and mounting of the table as in the case where a conventional handrail bracket is used on the top surface or outer periphery of the top plate. In addition, the arm portion has a hollow cross-section formed by a pair of side walls facing each other and an upper wall connecting the side walls, and has a shape with an open bottom surface. By extending from the lower surface of the fixed part to the lower surface of the support part and supporting the load from the lower surface, it is possible to achieve both a further increase in strength and light weight against twisting in the vertical and horizontal directions of the handrail. In addition, it has the advantage that it can be integrally molded, is easily mass-produced, and is aesthetically pleasing.

  Further, in the present invention, when the both side walls constituting the arm portion are formed so that the fixing portion side is wide and converges toward the support portion, the both side walls are supported from the lower surface of the fixing portion. It is extended to the lower surface of the part and the distance between both side walls on the fixing part side is wide so that it is strong against load in the vertical and horizontal directions and firmly fixed to the top plate. The distance between both side walls of the arm portion on the support portion side to be fixed is formed narrow so that the arm portion is unlikely to get in the way when grasping the handrail, and the length of the handrail can be used effectively. If a relatively short handrail for individuals is placed on the outer periphery of the door and the center part of each handrail is supported by a single bracket, walking and standing up assistance, body pulling, and sitting As well as the support of the body Convenient usage, such as hook and carrier-bag from the side is also possible.

  Furthermore, in the present invention, when the arm portion is recessed downward, the arm portion is further enhanced in resistance to a downward force by the arch effect, and the entire portion is lowered while ensuring strength. In addition to being able to reduce the size by suppressing the increase in the dents, the handrail not only forms a sufficient space for grasping the handrail between the handrail and the top plate or moving in the left-right direction as it is Since the bracket is hidden between the top plate and the top plate, it is excellent in aesthetics.

  Furthermore, in the present invention, both the outer side of the coupling position where the pair of side walls forming the arm part are coupled to the fixing part and the coupling position where the pair of side walls forming the arm part are coupled to the support part. When mounting holes for fixing screws for fixing to the back surface of the top plate and the bottom surface of the handrail are formed on the outside, the top plate and the handrail are firmly fixed and the mounting work is easy. In particular, since the fixing portion can be fixed uniformly to the entire back surface of the top plate in a balanced manner, it is possible to realize strong and stable fixing not only in the removal direction but also in the lateral load.

  Another invention of the present application is a handrail bracket for attaching a handrail arranged along the outer peripheral edge of the top plate, the fixing portion fixed to the back surface of the top plate, and the handrail. A fixing portion and an arm portion that connects the fixing portion and the supporting portion, and the fixing portion and the arm portion are connected to the connecting portion formed in the fixing portion, and the base portion of the arm portion is connected to the ceiling portion. It is characterized in that it can be reciprocated in the depth direction of the plate and can be fixed at a desired position so that the distance between the outer peripheral edge of the top plate and the handrail can be adjusted. In addition, the convenience of the handrail can be adjusted further by adjusting the distance between the top and the outer periphery of the handrail along the outer periphery of the top plate that is highly convenient in daily life.

  Further, in the another invention, the connecting part is a plate-like shape having a predetermined depth width and height that is suspended from a substantially central part in the width direction on the lower surface of the fixing part, and is arranged with a predetermined interval. A plurality of screw holes or a long screw hole extending in the depth direction, wherein the tip portion of the arm portion is integrally connected to the lower surface of the support portion, and the base portion is overlapped with a connecting portion that is suspended from the fixing portion. A screw long hole or screw hole corresponding to the screw hole or screw long hole is formed at a height position corresponding to the screw hole or screw long hole formed in the connecting portion, and the base portion of the arm portion And the connecting portion of the fixing portion are overlapped at a desired position in the depth direction, and a fixing screw is fastened to the screw hole and the screw long hole that are communicated with each other to fix the base portion of the arm portion and the connecting portion of the fixing portion. The outer periphery of the top plate and the handrail If the adjustable spacing, it is possible to reliably adjust the distance between the outer peripheral edge and handrail of the top plate with a simple structure and simple operation.

  Further, a groove-like recess having openings at both ends in the depth direction is formed on a vertical surface on one side of the connecting portion that is suspended from the lower surface of the fixing portion, and the screw hole or the screw long hole is formed in the groove-like recess. When the base portion of the arm portion is fitted in the groove-like recess portion so as to be reciprocally slidable in the depth direction, the groove-like recess portion in which the base portion of the arm portion is fitted is restricted in vertical movement. Sometimes the groove-like recess receives the vertical force applied to the handrail to strengthen the connection between the base and the sliding part, and also when adjusting the distance between the handrail and the top plate It is possible to adjust by reciprocating the arm part with the base part fitted in the groove-like concave part with the fixing screw loosened, which is very convenient and convenient.

  Furthermore, the handrail attached to the support portion can be fixed to the connecting portion of the fixing portion in a state where the arm portion can be rotated around the base portion and inverted to the depth side. Can be stored near the back of the top plate that does not protrude from the outer peripheral edge of the top plate, so that when the handrail is not used, it can be stored under the back of the top plate without obstructing without removing the handrail. There is no need for separate storage and labor, and in addition, handrails can be installed very easily by reversing the state as it is during use.

  The connecting portion is suspended from a substantially central portion in the width direction on the lower surface of the fixing portion and has a predetermined depth width and height, and the base portion of the arm portion is inserted into the connecting portion so as to reciprocate in the depth direction. A plurality of screw holes or screw long holes extending in the depth direction that are communicated with the insertion holes and arranged at predetermined intervals are formed, and the base portion includes screw holes or screw long holes formed in the connecting portion. A screw long hole or screw hole corresponding to the screw hole or screw long hole is formed at a coincident position, and the base portion of the arm portion is inserted into the insertion hole of the connecting portion to a desired position and communicated with each other. Further, by fastening a fixing screw to the screw hole and the screw long hole, and fixing the base portion of the arm portion and the connecting portion of the fixing portion, the distance between the outer peripheral edge of the top plate and the handrail can be adjusted. In this case, the base of the arm is the insertion hole In a more robust connection against the load of the supported by vertical and horizontal any direction by.

  According to the present invention, there is no hindrance to the use and installation of the top surface of the top plate as in the case of using a conventional handrail bracket, and it is extremely resistant to the vertical and horizontal loads of the handrail and is attached to the back surface of the top plate. Adhering firmly and stably, it is possible to achieve both weight reduction and downsizing and increase in strength, and there is no risk of interfering with the person's thigh when seated, making mass production easy and aesthetically superior. Therefore, the convenience of arranging the handrail along the outer periphery of the top plate such as a table can be easily realized. This also makes it possible to easily place handrails on an existing general table as a retrofit, and at that time, extra work such as drilling a mounting recess to stabilize bracket mounting on the back of the table, etc. This is also suitable for various arrangements of handrails such as arranging a plurality of relatively short handrails on the outer periphery of the top board.

  In another invention, it is easy to adjust the distance between the handrail and the outer periphery of the top plate, which improves the feeling of use, and can be inverted and stored directly behind the top plate. However, there is no problem.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 4 show a preferred embodiment of a handrail bracket 1 according to the present invention used when a bar-shaped handrail 6 having a circular cross section is attached along an outer peripheral edge 51 of a top plate 5 such as a table. Is shown.

  The handrail bracket 1 is fixed to the back surface 52 of the top plate 5, and is a fixing portion having a mounting surface 21 having a rectangular flat surface with a long side in the horizontal direction (the direction along the outer peripheral edge 51 of the top plate 5). 2, a support portion 3 having an arcuate support surface 31 that is curved with a predetermined diameter in accordance with the outer peripheral diameter of the handrail 6, and the fixing portion 2 and the support The arm portion 4 that connects the portion 3 is integrally formed of, for example, metal or resin.

  The arm portion 4 is formed of a pair of side walls 41, 42 facing each other and having a predetermined interval, and an upper wall 43 connecting the side walls. As shown in FIG. A pair of side walls 41, 42 forming the arm portion 4 extends from the lower surface 22 of the fixing portion 2 to the lower surface 32 of the support portion 3, and has a base of the pair of side walls 41, 42. The end portions 41a and 42a are coupled and connected to the lower surface 22 of the fixing portion 2 and the tip portions 41b and 42b are coupled to the lower surface 32 of the support portion 3, respectively.

  The distance between the pair of side walls 41 and 42 is formed so as to converge from the fixing portion 2 side toward the supporting portion 3 side so that the width W2 on the supporting portion 3 side becomes narrower than the width W1 on the fixing portion 2 side. Has been.

  As shown in FIGS. 2A and 2B, both outer sides of the coupling position where the base end portions 41a and 42a of the pair of side walls 41 and 42 forming the arm portion 4 are coupled to the lower surface 22 of the fixing portion 2; Mounting screw holes 23, 23, 23, 23 at the four corners, and mounting screw holes 33, on both outer sides of the coupling position where the tip portions 41 b, 42 b of the pair of side walls 41, 42 are coupled to the lower surface 32 of the support portion 3. 33 is formed so as to penetrate, and the mounting surface 21 of the fixing portion 2 is disposed at a predetermined position on the back surface 52 of the top plate 5, and set screws are inserted into mounting screw holes 23, 23, 23, 23 formed at the four corners of the mounting surface 21. 71, 71, 71, 71 are inserted and screwed from the bottom side, and the handrail bracket 1 is fixed.

  Similarly, as shown in FIG. 4 (a), a plurality of handrail brackets 1 are fixed in parallel at predetermined intervals in the direction of the outer peripheral edge 51 of the top plate 5, and as shown in FIGS. A handrail 6 is installed on the support surface 31 of the support portion 3 and set screws 72, 72 are inserted into the mounting screw holes 33, 33 formed through the support portion 3 from the lower surface side and fixed by screwing. The handrail 6 is attached along the outer peripheral edge 51 of the top plate 5 with a predetermined distance from the outer peripheral edge 51.

  The arm portion 4 is curved and recessed downward, and the arm portion is enhanced in resistance to a downward force by the arch effect, but the arm portion 4 has the structure as described above. Since the strength is also exhibited, the downward dent of the curve does not have to be so low that it interferes with the thigh of a person sitting on the chair for the use of the top plate 5. And, the curved shape that is curved downward is not only enough to secure a sufficient space between the handrail 6 and the outer peripheral edge 51 of the top plate 5 for moving the handrail in the horizontal direction. Since the handrail bracket 1 is hidden below the handrail 6 and the top plate 5, it is excellent in aesthetics.

  In the present embodiment, the arm portion 4 is substantially U-shaped with a hollow cross section having an open bottom surface formed by a pair of side walls 41, 42 and an upper wall 43 connecting both side walls. The arm 4 has sufficient strength against loads in the direction (axial direction of the handrail 6), and the arm portion 4 has an arch structure that curves downward, so that it is lightweight while using handrails. It can sufficiently withstand the applied load in the vertical and horizontal directions.

  According to the present embodiment, the mounting surface 21 of the fixing portion 2 is a rectangular shape having a long side in the left-right direction, and the entire surface is brought into contact with the back surface 52 of the top plate 5, and both side walls 41, 42 are connected to the fixing portion 2. Since the fixing screws 71, 71 are fixed at the four corners on both outer sides of the connecting positions to be connected, the top plate 5 can be firmly fixed in a very stable state.

  Further, in the present embodiment, the base end portions 41a and 42a of the pair of side walls 41 and 42 that are arranged at a predetermined interval so as to face each other and form a U-shaped cross section of the arm portion 4 are fixed. The lower surface 22 of the portion 2 and the tip portions 41b and 42b are respectively coupled to the lower surface 32 of the support portion 3 to support the load in a distributed manner from below, and the arm portion 4 on which the load applied to the handrail 6 acts preferentially during use. Since the connecting portion between the support portion 3 and the fixing portion 2 is reinforced, the durability is excellent.

  Further, since the distance between the pair of side walls 41 and 42 is formed wide on the fixing portion 2 side, the handrail 6 can be stably supported against the load in the vertical and horizontal directions, and the arm portion 4 and the fixing portion 2 can be supported. On the other hand, the support part 3 side is narrowly formed so that the length of the handrail 6 can be effectively used. For example, the grip width of the handrail 6 by the arm part 4 when the handrail 6 is gripped is reduced. Can be prevented, and usability is also improved.

  Furthermore, the support surface 31 of the support portion 3 is curved and recessed so as to be along the outer peripheral edge of the handrail 6, and is stable when the handrail 6 is fixed to the support portion 3 with set screws 72 and 72. Adhering is realized, and the positions of the set screws 72, 72 are on both outer sides of the connecting position where the both side walls are connected to the supporting portion, thereby realizing more stable handrail adhering.

  In the present embodiment, the arm portion 4 has a curved shape that is curved downward and is not limited to this. For example, the arm portion 4 may be a U-shape that is open upward (not shown). However, the cross-sectional rectangle, the cross-section arc shape, the inverted U-shape, etc. with the bottom open may be used (not shown). Furthermore, the shape of the handrail 6 is not limited to a circular cross section, and may be a rectangle or an inverted trapezoid (not shown).

  In the present embodiment, the handrail bracket 1 is integrally formed by casting. However, the production method is not limited to casting, and injection molding or other molding means may be used. Needless to say, the present invention can be carried out even if it is formed as a unit by bonding and other connection methods.

  According to the handrail bracket 1 of the present embodiment, a user can install a handrail on an existing table or other furniture having a top plate using the back surface of the top plate without choosing the type. In addition, there is no need for extra work such as mounting a mounting recess to stabilize the mounting of the bracket on the backside of the table, etc., and it is difficult to get in the way when using handrails, and it is simple while satisfying the strength required for use It is possible to provide a handrail bracket that can be manufactured in a shape suitable for casting with a simple structure.

  FIG. 4B is another example of use of the handrail bracket 1 of the present embodiment, in which relatively short handrails 7 are arranged along the outer periphery of the number of persons using the table (four). The handrail 7 is supported at its substantially central portion by the support portion 3 of one handrail bracket 1, and the fixing portion 2 is fixed to the back surface of the top plate 5.

  Such handrails are handrails for individual users who eat at the table rather than grabbing while walking, and each user stands up around the table or puts the body in a wheelchair on the table Short handrails, such as pulling on and off, supporting the body during eating and drinking, working, hooking personal belongings such as handbags or canes required during eating and working from both sides of the handrail However, the length can be effectively used without being interrupted by the arm 4, making it suitable for various uses at tables and counters. In addition, it is convenient for users, including storage of luggage carried by each person.
