Gets in the way of falling from a chair

Abstract

The device consists of a device to prevent falling from a chair when a person is sitting in one and tries to lie back. The device has as a minimum the gripping system for the foot of the chair (1) and the block that makes falling difficult (2) . It may also have a fall block (3). The block that makes falling difficult (2) consists of a block that changes the angle of rotation of the chair, causing it to turn to the side and cutting back movement. The fall block (3) adds a limit to the lateral fall if it were not prevented by the block that makes falling difficult (2). The chair can be created straight with the block that makes falling difficult (2) or the block that makes falling difficult (2) and the fall block (3) incorporated.

Description

Technical area of the invention

[0001] There are people who, when sitting in a chair, cannot avoid lying back on the back legs of the chair. This causes accidents because sometimes these people fall.

[0002] This problem also creates great discomfort for people around the person who likes to lie back.

[0003] The problem occurs mainly in meetings around a table and in schools.State of the art

[0004] There are chairs with an angle at the back legs of less than 90 degrees. If this angle is much lower, this will hinder the fall but at the same time compromise the stability of the chair. These types of chairs also take up more space.

[0005] In schools there are chairs glued to the table that avoid the problem, but this is not very practical.

[0006] If the chair is very heavy the problem is also avoided but this is also not practical.

[0007] Sometimes the chairs are nailed to the floor, but this is not practical either.Summary of the invention

[0008] The present invention relates to an apparatus for preventing a chair from falling when a person is sitting on one and tries to lie back.

[0009] To do this, a block that makes falling difficult (2) is added to the foot of the chair, which consists of a block with a rectangular triangle base that will be in line with the base of the chair foot. The side with the right angle is glued to the back of the chair leg and the acute angle is towards the back so that when the person tries to lie back, they will no longer be able to turn backwards but towards the side defined by the acute angle. The block can have a base shape other than a right-angled triangle. This is a block to adapt the shape of the chair leg or a rectangle / square together with the block with a right triangle base. The essential thing is that the block has a right angle on the back of the chair leg and an acute angle on the back of the chair.

[0010] The block that makes falling difficult (2) may form part of the initial design of the chair or it may be part of an independent device. If the latter is the case, it will be connected to the foot of the chair via a gripping system for the foot of the chair (1) which may consist of a custom-made block with a hole the exact dimensions of the foot of the chair or a system of clamps to allow it to be connected the device to any chair leg model.

[0011] The block that makes falling difficult (2) can be complemented with the fall block (3) which limits the angle of the fall if it is not stopped by the block that makes falling difficult (2).

[0012] The fall block (3) consists of a block glued to the block that makes falling difficult (2) with an obtuse angle on the side of the block that makes falling difficult (2) that is quite large and only allows a fall of a few degrees.

[0013] Embodiments and features, if any, described in this specification that do not fall within the scope of the claims should be interpreted as useful examples for understanding various embodiments of the invention.

[0014] According to one aspect, a chair is provided where the back legs include a block that makes falling difficult (2). In this embodiment there is no fall block (3) as the block that makes falling difficult (2) by itself works quite well.

[0015] In one embodiment, the legs of the chair with the block that makes falling difficult (2) also include the fall block (3) .

[0016] In one embodiment, only one back foot of the chair includes the block that makes falling difficult (2).

[0017] In one embodiment, only one back foot of the chair includes the block that makes falling difficult (2) together with the fall block (3).

[0018] In one embodiment, the block that makes falling difficult (2) together with the gripping system for the foot of the chair (1) create a device independent of the chair that can be removed and put on.

[0019] In one embodiment, the gripping system for the foot of the chair (1) is customized for a specific foot model.

[0020] In one embodiment, the gripping system for the foot of the chair (1) is based on a flexible system of flanges.

[0021] In one embodiment, the gripping system for the foot of the chair (1) together with the block that makes falling difficult (2) also includes the fall block (3).

[0022] The present invention is described below in detail, without limitation and by way of example, by means of a preferred embodiment or embodiment, represented in the attached drawings, in which: fig. 1 is a schematic and simplified perspective representation of an embodiment of the apparatus according to the invention. fig. 2 is a side view of an embodiment of the apparatus according to the invention. fig. 3 is another side view of an embodiment of the apparatus according to the invention. fig. 4 is a bottom view of an embodiment of the apparatus according to the invention. fig. 5 is a front view of an embodiment of the apparatus according to the invention. Description of the preferred embodiment

[0023] With reference to the figure, the preferred embodiment of the invention will now be described, in which the apparatus consists of a set of organs represented in said figure, assembled as described below.

[0024] The gripping system for the foot of the chair (1) which serves to connect the chair foot with the block that makes falling difficult (2). In this embodiment, it is a simple block created to adapt to a specific chair model and for this purpose it has a hole that coincides in shape with the shape of the chair's foot.

[0025] The block that makes falling difficult (2) which serves to divert the direction of movement of the chair when trying to go backwards. In this embodiment, it is a block with a right-angled triangle base with a very acute angle for greater deflection efficiency. The base of the block that makes falling difficult (2) is in line with the base of the chair leg.

[0026] Attached to the block that makes falling difficult (2) is the fall block (3) which, if the person forces the movement backwards too much, limits the angle of the fall. It consists of a triangular-shaped block as you can see in the reference figures.
