FR2528680A1 - Attachment for wooden bed slats to metal frame - comprises hook joining the slat and frame, and section with bent over slide enclosing sides - Google Patents

Abstract

The attachment has a hook (4) one end (3) of which hooks into a slot (2) in the frame (1). The other end (5) of the hook (4) fits into a hole (6) in the slat (7). The other part of the attachment consists of a section (8) which slides over the slat (7) and hook (4), thereby locking the hook (4) and slat (7) together. The section (8) has a slot (10) into which fits an elongated pin (11) forming part of the middle of the hook (4). Two sides (9) of the section (8) are bent over to enclose the slat (7).

Description

"Device for attaching the wooden slats of a box spring to the metal frame thereof
The invention relates to a device for attaching the wooden slats of a box spring to the metal frame thereof.

 Numerous solutions have already been proposed for mounting the wooden slats of a box spring with a metal frame which suppresses these slats.

 In particular, when the metal frame consists of a tubular element, it has already been proposed to mount the slats with respect to these tubular elements by using fasteners or connecting elements in the form of a spring, by making use of rivets which fix a terminal element into which is slid or to which the end of the slats is secured.

 The invention relates to a new fastening device, one element of which has the shape of a hook, one end of which can penetrate a slot in the tubular element of the metal frame of the bed base, and the other of which can be secured to both end of the slat quesdu hook without using any tool.

 To this end, the fastening device according to the invention consists on the one hand of a hook penetrating by one end into a cutout of said frame and by the other into an orifice formed in the corresponding slat, and, on the other hand , in one piece which can be slid over said slat and over said hook and be immobilized relative to the latter.

 In a preferred embodiment, the aforementioned part and hook are immobilized by snap-fastening of these two elements relative to each other.

 Other details and advantages of the invention will emerge from the description which will be given below of a device for attaching wooden slats from a box spring to the metal frame thereof, according to the invention. This description is given by way of example only and does not limit the invention. The reference notations refer to the attached figures.

 Figure 1 ex an exploded view showing the various elements of the fastening device and a section of a tubular member of a box spring frame and the end of a wooden slat.

 Figure 2 is a longitudinal sectional view of the fastening device mounted between a tubular member of a box spring and a wooden slat.

 The attachment device according to the invention is specially designed to secure the wooden slats of a box spring, by its ends, to an element of the metal frame thereof.

 In the figures, this tubular metallic element bears the reference 1. I1 has a series of cutouts of elongated shape 2. In each cutout 2 penetrates the end 3, folded in two directions, of the hook 4 whose opposite end 5 is folded back right angle to the general plane of the hook body 4.

 The folded end 5 is intended to penetrate into the orifice 6 formed right through in the end of a slat 7.

 Beforehand, the part 8 has been slid over this end of the batten 7. By bringing the part 8 towards the end of the batten 7, this part covers the hook 4 which thus remains fixed to this Butte because the end 5 is blocked in hole 6.

 The part 8 is open on one of its faces and has a cross section which is adapted to the thickness of the hook 4 which remains blocked on one of the faces of the slat 7.

 For the rest, the parts 8 have two lateral flaps 9, the rounding of which corresponds to the rounding of the lateral edges of the slat 7.

 Thanks to a ratchet system, the part 8 remains integral with the hook 4. This latching system may comprise, in the thickness of the flat part of the part 8, a slot 10 in which is housed an elongated lug 11 produced by stamping in the flat central part of the hook 4.

 At this stage, the hook 4 which is housed at its end 3 in the tubular element 1 is entirely secured to the slat 7 since the part 8 prevents any movement of the hook 4 relative to the slat 7.

 Other snap-fastening systems can obviously be imagined to block the part 8 on the hook 4 when the latter has penetrated by its flap 5 into the orifice 6.

 From the description which has just been given of the device for attaching the wooden slats of a box spring to the metal frame thereof, according to the invention, it is realized that it is possible to secure without the aid of any tool the slats of a box spring as part of it thanks to extremely reliable technical means and a very simple construction

Claims (5)

CLAIMS.  1. Device for attaching wooden slats of a box spring to the metal frame thereof, characterized in that it consists, on the one hand, of a hook 4 taking at one end 3 in a cutout 2 of said frame and by the other in an orifice 6 formed in the slat 7 and, on the other hand, in a part 8 which can be slid over said slat and over said hook to immobilize the latter relative to the milk.  2. Fastening device according to claim 1, characterized in that the aforementioned part and the hook are immobilized by snap-fastening of these two elements one relative to the other.  3. Fastening device according to claim 2, characterized in that the latching of the two aforementioned elements is achieved thanks to the presence in the part 8 of a slot 10 into which penetrates an elongated lug 11 which is part of a middle part of the hook 4.  4. Fastening device according to any one of claims 1 to 3, characterized in that the aforementioned part is open on one of its faces and has two lateral flaps 9 intended to enclose a slat 7.  5. Fastening device according to any one of the preceding claims, characterized in that the aforementioned part 8 has a cross section which adapts to the presence of the hook 4 on the slat 6.
