PATENTED AUG 3197:
SHEET 2 OF 3 FASTENING DEVICE FOR BALCONY RAILINGS, BANIS'IIZRS, BRIDGE RAILINGS AND TIME lLllllfE The present invention relates to a fastening device for balcony railings, banisters, bridge railing and the like. More particularly, the invention is concerned with a fastening device comprising a mounting socket adapted to be fixed to a balcony floor, a step or the like and having an opening in which an upright post of a railing or the like can be received and secured in the desired position by wedge means.
A fastening device of this sort is previously known in which the post is secured through driving a wedge into the socket between the post and an inclined wall surface of the socket. This known fastening device has been found to require a very precise positioning and mounting of the socket in order to avoid any difficulties in mounting the post in the proper vertical position.
The invention has for its object to provide an improved fastening device of the kind described which eliminates the above requirement on precise orientation and positioning of the socket when fastening it to the fixed building portions and permits the post to be adjusted and secured in the desired vertical position in a simple manner.
The fastening device of the invention is primarily characterized in that two opposite wall surfaces of the socket are movable relatively each other so as to permit the angle therebetween to be varied within certain limits.
In a preferred embodiment of the invention the device com prises a body adapted to be rigidly secured to a fixed building portion and a yoke-shaped member, the web and the legs of said member forming three of the four walls of the mounting socket, said yoke-shaped member being adapted to be pivotally connected to the body with its legs so as to permit limited rotation thereof.
The invention will now be described in greater detail, reference being had to the accompanying drawings, in which:
FIG. I is a perspective view, partly in section, of a fastening device according to one embodiment of the invention,
FIGS. 2 and 3 show vertical and horizontal sections, respectively, of the device according to FIG. 1, and
FIGS. 4 and 5 show a perspective view and a plan view, respectively, of a fastening device according to another embodiment of the invention.
The fastening device shown in FIGS. I to 3 includes a body secured to a fixed building portion and comprising a housing 11 having a substantially rectangular cross section, and a sheet metal strip 2 passing through slots in two opposite walls of the housing I. The central portion of the metal strip 2 forms a bottom in the housing 1 and the two end portions thereof an anchorage means for securing the body to a balcony floor or the like in connection with the casting thereof. The two vertical walls of the housing I are each provided with a circular pin 3 secured thereto and projecting into the inner of the housing, said two pins 3 being axially aligned to form pivot pins for a sheet metal yoke 4 having in each leg an opening for receiving the respective pin 3. In order to facilitate the insertion of the yoke 4 into the body housing l the legs of the yoke 41 are at their free ends slightly bent towards each other so that the yoke can be coupled to the pivot pins 3 simply through pushing the yoke into the housing I. As appears from FIG. 2, the vertical height of the yoke 4 is shorter than the internal height of the body housing I. Here y the yoke 45 is permitted to pivot on pins 3.
Reference numeral 5 designates a wedge dolly comprising a central portion adapted to be inserted between the legs of the yoke 4 and having the shape of a plate 6 of a width corresponding to the distance between the legs of the yoke, and two end portions 7 each having a groove d for receiving a locking wedge 9. Provided that the central portion 6 of the wedge dolly 5 has a sufficient width the wedge dolly 5 will also serve as locking means to prevent disengagement of the yoke 4 from the pivot pins 3. In order to permit the wedge dolly 5 to be kept in its desired position during the mounting of a banister or post the wedge dolly is on its back, i.e. on the side thereof facing the housing 11, provided with two lips I0 adapted to be inserted into the opening of the housing 1. When mounting a post II in the fastening device shown in FIGS. ii to 3 said post is inserted into the mountingsocket formed by the web and the legs of the yoke 41 and by the wedge dolly, whereupon a wedge 9 is driven into each groove 8 to lock the post if in said mounting socket. Through providing a wedge on each side of the pivoting axis of the yoke 4 as above described, it is possible through varying the extent of driving in the different wedges 9 to lock the post 11 in the proper vertical position even if the body I has been mounted in a skew position. The bottom surfaces of the wedge-receiving. grooves b can be parallel to the back of the wedge dolly 5. However, said surfaces may preferably form with the back of the wedge dolly an acute angle corresponding to the wedge angle thereby causing an increased contact surface between the post and each wedge 9.
In case of a casted building portion the body of the fastening device is preferably mounted in connection with the casting of said building portion. The body can be secured to the form in a very simple manner.
In the fastening device shown in FIGS. 4 and 5 the body to be secured to a fixed building portion consists of a box structure, generally designated M on the drawings, said box structure having two parallel box legs 22. The body is provided with an anchorage means in the shape of a rod 23 extending in a transverse direction through the two box legs 22. The rod 23 serves also as a pivot axis for a metal yoke 24 having its legs displaceably received in the box legs 22 and being provided with elongated openings 25 through which the rod 23 passes. in order to permit a limited pivoting movement of the yoke 24 around the rod 23 when the yoke is retracted from the body as far as possible, the yoke has been given a height slightly shorter than the internal height of each box leg 22.
Reference numeral 26 designates a wedge dolly in the shape of a plate having a central portion adapted to be inserted between the legs of the yoke 24, and two opposite end portions each having, on the side thereof remote from the body, a groove for receiving a locking wedge 27. As appears from the drawings, the two wedges 27 are disposed on opposite sides of the pivoting axis of the yoke 24 formed by the rod 23. Hereby it is possible, through varying the extent of driving in the wedges 27, to fix a post 23 inserted into the fastening device in the proper vertical position irrespectively of any skew mounting of the body of the fastening device.
Naturally, the invention is not restricted to the embodiments shown on the drawings. For instance, the device of FIGS. d and 5 may be provided with a body with a single box leg instead of two parallel box legs, for receiving the two legs of the yoke. Moreover, the body can have such an inner width that it will permit a limited displacement of the yoke in a direction parallel to the rod 23.
