Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a pedestal that is attached to the legs of furniture such as a desk or sofa and is used to stably install the desk or sofa. This relates to a pedestal that reduces manufacturing costs by simplifying the process.

[Conventional technology]

2. Description of the Related Art Conventionally, a pedestal shown in FIG. 5 is generally known as a pedestal that can be attached to the legs of furniture such as a desk or a sofa.

This is done by fitting the head b of a special bolt a made for the pedestal into the recess d of the base c, and creating an exterior with a through hole through which the shaft of the bolt a can be inserted from above. The part e was fitted externally, and the bolt a was fixed to the base c by an insert method. In addition, the base c and the exterior part e are fitted by providing a protrusion g and a corresponding recess f at the appropriate locations on both sides, and in order to ensure the fit, the base c and the exterior part e are fitted in the recess f or the outer periphery of the base. Adhesive was applied as needed.

[Problem that the invention attempts to solve]

However, since pedestal c above uses special bolts, manufacturing costs cannot be reduced and it is not suitable for small-lot production, and bolt a is fixed by pouring resin into pre-supported bolt a. The bolt head was buried, making it difficult to work with and the manufacturing process was complicated. In addition, the fixation between the base and the exterior part is simply by engaging a convex part and a concave part, so the fixation is incomplete and easy to come off, so it is necessary to apply an adhesive further to make sure the fixation. This made the manufacturing process even more complicated.

[Means for solving problems]

The present invention was made to solve the above problems, and uses a general-purpose standard bolt as the bolt, and provides a locking mechanism with a non-return function as a means of connecting the base and the exterior part. The purpose of this project is to simplify the manufacturing process and reduce manufacturing costs. a base having a recess into which the parts can be tightly fitted and having a depth sufficient to allow the shaft of the bolt to stand upright; a through hole through which the shaft is inserted; a locking mechanism comprising: a locking convex portion provided on one of the base and the exterior portion; and a locking concave portion configured to lock onto the locking convex portion on the other side; It is characterized in that the exterior part is fitted to the base after bolts are erected on the base.

[Effect]

With a pedestal constructed in this way, ready-made standard bolts can be used, making it highly economical.Also, the pedestal and exterior part can be easily and securely fitted with the locking mechanism, so adhesive can be applied to the pedestal. There will be no need for it.

〔Example〕

Next, the details of the present invention will be explained based on the illustrated embodiment.The illustrated one is an embodiment of the pedestal embodying the present invention, and in the figure, 1 is the base, 2 is the exterior part, and 3 is the bolt. It is. Any bolt 3 may be used depending on the specifications of the pedestal, as long as it has a head with a polygonal cross section so that the shaft portion 8 of the bolt 3 does not rotate idly relative to the pedestal 1. In this case, a general hexagonal bolt is used.

For example, the base 1 and the exterior part 2 are made of ABS resin or 6
It is preferable to use a hard synthetic resin such as nylon that can be easily molded in one piece, but it may also be possible to plate the surface for decorative effects or to make only the exterior part from metal such as aluminum. It is.

The base 1 is provided with an outer circumferential wall 4 for fitting on the outer periphery of the upper surface of a disc-shaped bottom plate 16, and a raised part 5 is provided in the center, and the head 6 of the bolt 3 is prevented from rotating on the raised part 5. A recess 7 is provided that matches the shape of the bolt head 6 so that it can be tightly fitted in the state. In this embodiment, a general hexagonal bolt is used for the bolt, so the recess 7 also has a hexagonal cross section to match this, but this shape can be changed as appropriate to match the shape of the bolt head 6. sell. Further, the depth of the recess 7 is set to be sufficient for the shaft portion 8 to stand on its own when the bolt head 7 is inserted and the shaft portion 8 is raised vertically. In addition, a notch 9 is provided in a part of the opposing outer peripheral wall 4.
is provided in the notch 9, stands up from the bottom plate 16, has an outward claw at the tip, and
The locking pieces 10, 1 are elastically biased outward in the diametrical direction.
0 is set. Further, holes 11, 11 are provided between the outer peripheral wall 4 and the raised portion 5, and the protrusions 12, 11 of the exterior portion 2 are provided.
The fitting between the exterior part 2 and the base 1 is made more reliable by fitting the hole 12.
The number of 1s is not limited.

What is shown by 2 in the figure is an exterior part that fits onto the base 1, and is a hollow container with an appearance that is approximately inverted dovetail, and has a through hole having a diameter through which the shaft part 8 of the bolt 3 can be inserted. 13, and a peripheral wall 19 extending below the inner wall so as to press and fix the bolt head 6 when the bolt head 6 is fitted onto the base 1. In addition, the lower end inner peripheral wall 14
are oppositely carved with locking recesses 15, 15 into which the locking pieces 10, 10 can be locked, and hollow holes are formed on the inner wall of the exterior part at positions corresponding to the holes 11, 11 of the base. The protrusions 12, 12 are provided so that they can be fitted into the holes 11, 11.

In the illustrated embodiment, the locking pieces 10, 10 are provided on the base 1, and the protrusions 12, 12 are provided on the exterior part 2, but the respective positions may be reversed or they may be combined. This is possible by appropriately selecting the wall thickness of 2. In addition, as a locking mechanism, the fourth
As shown in the figure, a locking protrusion 17 having a mushroom-like appearance and elastically biased on one of the base 1 or the exterior part 2,
17, and a locking hole 1 having a stepped portion that fits into the locking protrusions 17 and passes through the bottom plate 16 on the other side.
8 and 18 may be adopted as appropriate, and the use of other locking mechanisms as long as they have a non-returning effect is not hindered.

To assemble and use such a pedestal, first, the bolt head 6 is tightly fitted into the recess and the bolt 3 is erected and fixed. At this time, the bolt head 6 has a polygonal cross section, and the recess 7 corresponds to the shape of the head and is deep enough to hold the bolt 3.
Bolt 3 is stable and self-supporting. Next, insert the shaft part 8 into the through hole 13 of the exterior part 2 and attach it to the base 1.
At this time, the locking pieces 10, 1
0 comes into contact with the lower end of the outer periphery of the exterior portion, apply some force to lock the locking pieces 10, 10 in the locking recesses 15, 15. Since the locking pieces 10, 10 have a non-return mechanism, the fitting between the base 1 and the exterior part 2 is reliable, and even if the base is handled somewhat roughly after the fitting, the base 1 and the exterior part 2 will remain intact. It is extremely easy to handle without separating.

Further, as described above, the locking mechanism includes the locking protrusion 17 as shown in FIG.
When using a locking hole 18 penetrating through the locking hole 18, the locking protrusion 17, which is expanded and locked within the enlarged diameter stepped portion of the locking hole 18, is removed from the bottom surface of the bottom plate 16 by reducing its diameter. By doing this, it is possible to create a structure in which the base 1 and the exterior part 2 that have been once fitted can be separated again.In this case, the bolts can be replaced even after the base is installed, so the base 1 and the exterior Part 2 and bolt 3
In addition to being able to flexibly deal with damage caused by any of the above, it is also possible to reuse the pedestal once used for other legs.

The pedestal assembled in this way is attached to the legs of a desk or bookshelf using the shaft part 8, and the shaft part 8 is rotated and adjusted as appropriate to stably install the desk or bookshelf. When adjusting the position, the bolt 3 is loaded in the vertical direction, so the fixation of the bolt 3 to the base 1 and the exterior part becomes a problem, but in the present invention, the bolt 3 is installed in the recess 7 to prevent rotation. Since the bolt head 6 is fitted and fixed in this state, and the bolt head 6 is also pressed and fixed by the peripheral wall 19, there is no looseness of the bolt 3. Furthermore, since the exterior part 2 and the base 1 are securely fixed by the locking mechanism and the protrusions 12, 12, the height of the pedestal can be adjusted by gripping the exterior part 2 without causing the exterior part 2 to spin idly. It is something that can be done.

In this embodiment, the exterior part 2 is fitted externally to the base 1, but it is also possible to change the structure of the fitting part and fit it internally to the base 1. In this case, the exterior part 2 can be fitted inside the base 1. Since the threading is done by grasping the base, it does not require much strength to fit and fix the base and the exterior part.

[Effect of idea]

According to the present invention, ready-made standard bolts can be used for the shaft of the pedestal, which not only facilitates parts procurement but also reduces manufacturing costs. Since the resin is simply fitted into the recess without pouring resin, it is possible to shorten the work process and work time. In addition, the base and the exterior part can be easily and reliably fitted by the engagement mechanism with a non-return mechanism.
There is no need to apply adhesive, making assembly of the pedestal easier. Furthermore, since there is no need for pre-assembly with adhesive, the base and exterior can be stored separately and assembled when necessary, so the exterior, base, and bolts can be combined as needed and attached to various legs. It is also possible to respond accordingly.
