Abstract

PURPOSE: To provide a seat arrangement structure structurally simple and strong by providing two semi-clamps secured to a pedestal and a third auxiliary member to match in overall shape. CONSTITUTION: A leg part 2 is secured to a horizontal pedestal 1 by two semi- clamps 6, 7. The clamps 6, 7 are made to match the pedestal 1 in outer form. A means capable of changing gripping toward the pedestal 1 comprises the tail members 11, 12 of the clamps 6, 7 which are arranged in parallel and a third auxiliary member 13 which is parallel to the member 12. They are so formed that their overall outer shapes match the inner shape of the upper end of the tubular leg 2. The auxiliary member 13 includes a means (e.g. hole 17 and rod 16 of member 12) which is guided so that the clamps 6, 7 are held in a working condition and which can be positioned at the center and a screw 18 for adjusting the positions of the clamps 6, 7 relative to the inner peripheral surface of the tubular leg part 2, and is fixed in an operating position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a seat arrangement structure that is simple and sturdy.

[Conventional technology]

A well-known seat arrangement is one in which a horizontal pedestal is supported by support legs and has a seat surface screwed onto the top surface. One of the problems with this type of seat arrangement is the fixation of the support legs to the horizontal cradle. Quite complex means are generally used, including numerous screws and welds, which make the arrangement unattractive.

Another problem with these designs was the mechanism for securing the seat to the pedestal itself.

Such seats are typically manufactured in a single casting or molding process, and must incorporate reinforcement to support the weight that the seat is subjected to in use.

[Structure of the Invention] In order to solve the above-mentioned problem, in a structure having a highly rigid horizontal pedestal supported by a support leg and to which a seat surface and an arbitrary auxiliary table are fixed, the leg is made of two members. track clamps, i.e. clamps that are self-completed and whose external contours generally correspond to the external contours of the above-mentioned cradle, these clamps having tail members formed in parallel with the extension tracks and the above-mentioned semi-clamps. means for changing the grip on the pedestal completed by a third member parallel to the extension of at least one of the legs; The two extensions and the auxiliary member are fitted inside this leg, and the auxiliary member is guided and centered so that the semi-clamp is placed in the activated state. and a screw for adjusting the position of the semi-clamp with respect to the inner circumferential surface of the tubular leg, thereby fixing the semi-clamp in the operating position.

The extension of the semi-clamp, forming the main clamp as well as the auxiliary member, fixes this extension in the appropriate operating position and guides the movement along the inscribed surface of said cylindrical leg end. For this purpose, it is fixed by a pin that can be easily inserted into a corresponding hole in an adjacent part.

The auxiliary members of said semi-clamp are fixed by screws threaded into the screw holes, these screws being free to move through one adjacent inner hole of said semi-clamp and supported abutting on another extension; The screw heads are located in opposing openings in the leg ends so that they can be accessed with a conventional screwdriver or the like.

One of the semi-clamps is threaded along the length of the inner surface and has a threaded protrusion that crosses a hole provided in the pedestal, and the other semi-clamp passes through the pedestal,
It has a hole into which a screw is inserted, which screws into the projection and thereby fixes the semi-clamp to the pedestal.

The pedestal has a tubular shape and has an end member attached to at least one end of the pedestal, the end member being located on a side of the adjacent seating surface and having a bent extension. , this extension is fitted onto the end of the pedestal and fixed with screws and bolts.

All seats consist of two similar parts constituting the actual seating surface, with rear parts adapted to fit respectively the front and top parts of the cradle, with screws and bolts on the cradle. It is positioned and fixed by.

The pedestal has a rectangular cross section, and is positioned and fixed in a laterally inclined state. The sloping backrest of the seat is positioned and fixed on the wide side of the pedestal.

〔Example〕

As is clear from each figure, the structure for constructing seats in rows is composed of a tubular pedestal 1 with a rectangular cross section.
It is supported by a tubular leg portion 21 which is threaded.

The connection of the tubular leg 2 to the pedestal 1 is realized by means of two semi-clamps 6.7. This semi-clamp has a "C" shape that matches the outer shape of the pedestal. The semi-clamp 6 has a convex protrusion 8 with a threaded portion formed on its inner surface, while the semi-clamp 7 has a hole 9 formed therein.

The screw 10 passes through this hole and the pedestal 1 and is screwed into the threaded portion of the projection 8. In this way, the semi-clamp is fixed to the pedestal 1.

The semi-clamp 6.7 is provided with elongated tracks or bases 11.12, which can be mated with each other. When they are placed into operation, they are completed by the member 13 adjacent the extension 12. The shape of the three juxtaposed members 11, 12, 13 corresponds to the inner contour of the upper end of the leg 2, i.e. the inner edge corresponds to the three members 11, 12, 13.

The leg member 11 has a protruding rod 14 that can fit into a hole 15 formed in the leg member 12. On the other hand, the leg member 12 has a rod 16 that can fit into a hole 17 formed in the member 13.
is installed protrudingly. The projections and holes are designed to hold the members 12 and 13 when they are moved in and out in the process described later, and to fix each member in the operating state.

The member 13 is fixed by two screws 18 screwed into the screw holes. This screw passes freely through the hole 19 in the foot member 12 and is able to abut the foot member 11.

The screw head is located in an opposite opening 20 in the leg 2 which is accessible with conventional tools.

When screw 18 is tightened, members 11 and 13 are expanded against the inner surface of leg 2, so that semi-clamps 6 and 7 are completely joined together in said leg. Further, the semi-clamp can be easily disassembled simply by loosening the screw 18.

The seat is made of two similar members 21 that constitute the actual seat and backrest, such as a plate-like packet with punched small holes.
and 22. These members have sloped rear portions constituting their main surfaces, and are positioned and fixed to both the front and top surfaces of the pedestal 1 by screws 25 and bolts 26 or other similar fastening means. ing.

A side or end member 27 is fitted onto one of both ends of the pedestal 1. These members have bent extensions 28 for fitting into the ends of the cradle and are secured by screws 29. All can be supplemented with an auxiliary table secured to one of the ends of the pedestal using conventional joining methods.

From all the above descriptions the foot member 1 with the auxiliary member 13
It can be seen that the joining of the leg 2 to the pedestal 1 using a semi-clamp 6.7 having a diameter of 1.12 is very simple and at the same time robust. Moreover, there are no visible joints or screws, which provide an attractive and compact seating arrangement compared to many other well-known structures where various screws, bolts, and unsightly joint marks are visible.

On the other hand, the arrangement of the seating surfaces is very simple since they are joined to the pedestal. Nevertheless, the seat is very sturdy and the rear portion 23,24 provides a large contact area for the user.

The seat and backrest are made from a single piece of material, such as a stamped board in the shape of a shallow packet.

Furthermore, they are self-supporting, i.e. the sides of the part exhibit sufficient rigidity, so that no additional reinforcement is required, and no special No mechanism required.

The materials used in the assembly of the components of the chair, the geometries and other additional and auxiliary details of the same are within the scope of the invention, provided they do not affect the essential properties of the chair. It is something outside.
