Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for a parapet that covers a parapet built up around a rooftop or a balcony.

[0002]

[Problems to be solved by conventional technologies and devices]

 A structure shown in FIG. 8 is known as a conventional mounting structure of a headstock. The Kasaki 50 is a long member having a generally U-shaped cross section, which is composed of a top surface portion 51 and both side surface portions 53, and is attached so as to cover the top of the parapet P. In the structure shown in the figure, two bolts 57 stand up from the base plate 56, which is positioned and fixed to the top surface of the parapet P by the anchor bolts 55, and the receiving plate 61 of the headstock 50 is further extended by using these bolts 57. It is fixed. The headstock 50 is attached to the receiving plate 61 so as to be fitted from above.

A conventional receiving plate 61 has a cross-sectional shape as shown in FIG. 8, a central portion thereof is flat, a fixing portion 64 attached to the two bolts 57, and both end portions thereof are diagonally outward and It is formed in a locking portion 65 that extends downward and is locked to the inner lower end portion 54 of both side surface portions 53 of the headstock 50. In addition, at a middle position between the fixed portion 64 and the both locking portions 65, a support which is formed on a flat upper end surface projecting upward and abuts on the bottom surface seat portion 52 of the top surface portion 51 of the headstock 50 to support the headstock 50. The part 68 is configured. The headstock 50 is attached to the receiving plate 61 from above. In such a conventional mounting structure, for example, when an unreasonable external force is applied, the top surface portion 51 of the headstock 50 is likely to be dented, and the lower ends of both side surface portions 53 are likely to project outward. Further, when the headstock 50 is an extrusion-molded product of a low-foam resin, the residual stress at the time of molding may be released due to changes in temperature and temperature changes due to sunlight, and thus deformation may occur. In particular, the top surface in the installed state receives the most sunlight and the temperature rises most. Therefore, residual stress is released in this part, and the top surface bends in the direction in which it contracts, that is, in the installed state, the side surface 53 There was a tendency for the lower end of the to deform so as to project outward. Since such deformation causes the locking by the locking portion 65 to be disengaged or displaced, it causes rattling or falling of the headstock 50.

As a measure for preventing the deformation as described above, conventionally, a protrusion 70 that is hooked on the locking portion 65 of the receiving plate 61 is formed as shown in FIG. 9 so that the lower ends of both side surface portions 53 of the headstock 50 do not spread laterally. I was doing. However, such a protrusion 70 is apt to be chipped if an excessive force is applied at the time of mounting or at other times, and it is not easy to process it, which is an insufficient countermeasure.

Further, the rigidity of the receiving plate 61 is considerably high, and a large force is required for the locking portion 65 of the plate 61 to get over the projection 70 when the headstock 50 is fitted. This lowers the attachability of the headstock 50, and cracks may occur in the top surface portion 51 if forced.

The present invention has been devised in order to effectively solve the above-mentioned conventional technical problems. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a mounting structure for a cap tree that prevents the above-described deformation of the cap tree and that does not deteriorate the mountability.

[0007]

[Means for Solving the Problems]

 The mounting structure of the headstock according to the present invention has the following structure in order to solve the problems of the prior art as described above and achieve the object. That is, in a mounting structure for mounting a cap tree on the upper end of a parapet via a mounting bracket, the mounting bracket includes a locking portion for locking the inner peripheral lower end of both side surfaces of the cap tree, and The abutment portion that abuts the bottom of the top surface of the head tree. Then, the abutting portion of the mounting bracket elastically urges the top surface of the headstock upward, and the elastic contact of the corresponding contact portion causes the corresponding contact portion and the locking portion to cooperate with each other. The head tree is configured to be stretched in the vertical direction between the inner peripheral side lower end portions of the both side surface portions and the bottom portion of the top surface portion.

[0008]

[Operation and Effect of the Invention] In the mounting structure of the headstock according to the present invention, the headstock is fitted onto the mounting bracket by lowering and pushing it from above the mounting bracket. At the bottom of the top surface of the top plate, the Kasaki is pressed down to bend the contact part of the mounting bracket, and is pushed in until the lower ends of both side parts pass over the locking part of the mounting bracket and come under it. After that, when the pushing force is released, the headstock is pushed up by the elastic force of the abutment part of the mounting bracket, and the locking part of the mounting bracket also abuts on the lower end of the inner peripheral side of both sides of the heading bracket. In this state, the abutment part and the locking part of the mounting bracket push the head tree vertically. Therefore, even if the top surface of the Kasagi attempts to deform in the direction of depression due to changes in temperature and sunshine, the mounting brackets will be pulled up and down inside the Kasagi to prevent the deformation. Further, even if an unreasonable external force acts on the headstock in the installed state, the abutment part of the metal fitting is elastically deformed to absorb the outer force instead of deforming the headstock.

When the operator pushes in the headstock, the abutment portion of the mounting bracket is easily elastically deformed when the operator pushes the headstock in with a large force, so that the headstock can be pushed in easily without being applied an excessive force.

【Example】

 Hereinafter, an embodiment of a mounting structure of a headstock according to the present invention will be described with reference to FIGS. 1 to 7.

FIG. 1 is a perspective view showing a receiving plate as a mounting member used in the first embodiment of the present invention. This receiving plate 1 is a member that is fixedly attached to the two bolts of the base plate, and the head board is fitted therein, similarly to the receiving plate of FIG. 8 described in the prior art.

The receiving plate 1 comprises a relatively thick thick material portion 2 and a relatively thin thin material portion 3, both of which are integrally formed by welding, screwing, rivets or the like. The thick material portion 2 includes a central flat fixing portion 4 which is attached to two bolts of the base plate, locking portions 5 which extend obliquely downward and outward on both sides, and a fixing portion which is bent at a substantially right angle in cross section. 4 and the locking portion 5 are connected to each other. The connecting portion 6 can be omitted by extending the fixing portion 4 straightly to the left and right and directly connecting to the locking portion 5, and the shape of the thick material portion 2 can be simplified. The fixing portion 4 has two elongated holes 7 through which two bolts of the base plate are inserted.

The thin material portion 3 is fixed to both the locking portions 5 of the thick material portion 2 with rivets, extends upward along the inclination direction of the locking portion 5, and is predetermined from the lowermost end portion of the locking portion 5. At a height H (see FIG. 2), the contact portion 8 is formed by being bent inward so as to be substantially horizontal. The contact portion 8 is located at a height S (see FIG. 2) from the connecting portion 6 of the thick material portion 2, and the portion corresponding to this height S constitutes the leaf spring portion 9.

With reference to FIGS. 2 to 4, a mounting operation of the headstock 10 will be described. The headstock 10 is pushed straight down so as to cover the receiving plate 1 from above. The bottom portion 12 that protrudes inward of the top surface portion 11 of the headstock 10 (may not be protruding) hits the abutting portion 8 of the receiving plate 1 and further pushes the headboard 10 while elastically deforming the leaf spring portion 9. The lower end inward projection 14 of the surface portion 13 rides over the locking portion 5 of the receiving plate 1 and becomes the state of FIG. The state of FIG. 3 is a state in which the headstock 10 is sufficiently pushed in, and the distance between the connecting portion 6 and the abutting portion 8 contracts from S to S _1, and the upper end inward projection 14 of the headstock 10 is reduced. The end face floats from the lower end of the locking portion 5 of the receiving plate 1 by a distance S ₃ . When the pushing operation is stopped in the state of FIG. 3, the contact portion 8 pushes up the headstock 10 due to the elasticity of the leaf spring portion 9, and the upper end surface of the lower end inward projection 14 is the lower end portion of the locking portion 5 as shown in FIG. The head board 10 is fixed to the receiving plate 1 by hitting. At this time, the distance between the connecting portion 6 and the contact portion 8 is S ₂ which is larger than S ₁ .

The headstock 10 installed as described above is in a state in which the receiving plate 1 is vertically stretched between the bottom portion 12 of the top surface portion 11 and the upper end surface of the lower end inward projection 14. Therefore, even if the top surface portion 11 is to be deformed into a curved shape such that it is depressed at the central portion thereof, the elastic force of the receiving plate 1 acts to prevent the deformation. Further, even if an unreasonable external force is applied from above the headstock 10, the leaf spring portion 9 of the receiving plate 1 is elastically deformed and absorbs the external force, so that the headboard 10 is not deformed.

FIG. 5 is a perspective view showing a receiving plate as a mounting member used in the second embodiment of the present invention. The receiving plate 21 is also composed of a thick material portion 22 and a thin material portion 23, which are integrally connected by screwing. The thick material portion 22 constitutes a fixing portion 24 that is attached to the two bolts of the base plate, and two elongated holes 27 through which the two bolts are inserted are formed. Both ends in the width direction of the fixing portion 24 are formed into ribs by being folded back substantially at right angles so as to obtain sufficient strength. Both ends in the longitudinal direction are bent obliquely downward outward to form a connecting portion 26, and the thin material portion 23 is screwed to the connecting portion 26.

The thin material portion 23 is bent a little above the screwed portion to form a leaf spring portion 29, the lower end portion of which is a locking portion 25 against the headstock, and the upper end portion thereof is against the headstock. The contact portion 28 is configured. In this embodiment, since elastic deformation of the locking portion 25 can be expected to some extent as compared with the first embodiment, the force when the lower end inward projection of the headstock gets over the locking portion 25 is small, and the mounting property is good. Will be even better.

FIGS. 6 and 7 show the receiving plates 31 and 41 of the third or fourth embodiment, respectively, and the thick material portions 32 and 42 are the same as the thick material portions of the first embodiment. It The thin material portions 33 and 43 respectively have a spring function to form abutting portions 38 and 48. As in the other embodiments, the thin material portions 33 and 43 are elastically deformed to enhance the mounting property, and the thin material portions 33 and 43 are vertically moved inside the headboard. It prevents the top surface from curving or warping effectively.
