Description

TECHNICAL FIELD

This patent application refers generally to an arm-rest and in particular to an adjustable and dismountable arm-rest.

OBJECT OF THE INVENTION

This patent application is intended to provide an adjustable and dismountable arm-rest to support arms for long periods of time, to permit stability when holding items that require precision such as binoculars, photographic cameras, or other equipment and/or accessories, that have a determined weight and would cause fatigue while monitoring in inhospitable places to capture the behaviour of a particular event, e.g. opening of a flower, behaviour of animals, among others.

The arm-rest is manufactured is such a way that when the user is seated he has this arm-rest which is adjustable in length, which makes it possible to adjust to different user heights, providing them with a firm support for the best stability and reduce tiredness that would be caused by holding a certain object such as a camera, for long periods of time.

BACKGROUND

When you are in a field or forest and have the need to capture natural contexts and it is not necessary to alter the location of the objects, and to wait the necessary time for the natural contexts to happen in order to capture them. Therefore, the number of objects taken should be reduced, be of light weight and small size for loading.

At all times the user is prepared to capture the images, which normally requires holding photographic or video cameras, binoculars for long periods of time, and would cause tiredness and instability in their arms. It is for this reason that this patent application of arm-rest is used as it is light, dismountable and adjustable to the height of the user as it is possible to rest his arms while on high alert to capture the scene at the necessary precise moment. This is possible without altering the context with large objects, such as those that are commercially available, which consists of chairs or benches in order to articulate the arm-rest.

DETAILED DESCRIPTION OF THE INVENTION

The arm-rest, which is the motive for this patent application, consists of an adjustable and dismountable arm-rest that is placed on the thighs of the user, and the top provides support for the arms, and its front view is represented in FIG. 1

The arm-rest (1) includes: a first (2) and second (3) vertical posts of the same length. The length of construction is variable between 35 cm and no more than 45 cm, as this is the average distance with the arms extended to the front with the legs flexed, when a person is sitting.

The vertical posts are separated by a first and second distance, the first distance is larger than the second, so that the distance between them decreases in the lower part.

In FIG. 7, is shown the for longitudinal cross-section of the vertical post (2, 3) in which is shown in the middle part (4) a diameter, and at its extremities (5a and 5b) a second smaller diameter, forming a step (6) at each of the extremities. The second diameters located at the extremities are equal in size.

Preferably the first diameter in the middle of it is at least 3 mm larger than the second diameters contained at its extremities

In particular, the first diameter is 2.5 cm wide and 22 cm long; and the higher and lower extremities of the vertical posts presents a length preferably from 8 cm to 11 cm.

In FIG. 3, is shown a schematic representation of the exploded view of the arm-rest for which is distinguishable: as the higher extremities (5a) of the both vertical posts are temporarily fixed to the first horizontal rail (7), and the lowest ext remit (5b) of both vertical posts are temporarily fixed to the second horizontal rail (8), with less distance between them.

In particular, the first and second horizontal rails (7 and 8), represented in FIGS. 4, 5 and 6, consist of a prismatic rectangular shape whose wider section placed perpendicular to the vertical posts to provide a larger support space for the arms and thighs of the user whilst he is waiting. At the ends of each of the first and second horizontal rails there are a set of holes (9) equally spaced, that pass through the whole of its thickness and equal in number and size, where each hole of the set of perforations (9) are made with an inclination of 10° towards the centre or midpoint of the horizontal rail and the diameter of each hole coincides with the corresponding second hole diameter (5a and 5b) of each of the vertical posts (3 and 4), so that the top of each vertical post passes through the holes at each end of the horizontal rails, using the same perforation number, (for example: put it into perforation 1 of each extremity) and slide it on to the first horizontal rail (7) to highest ends of the first (3) and second (4) vertical posts that presents a second diameter until it reaches the steps (6), formed at the end of each extremity by the change of diameters in its middle part; and each of the lower extremities of the vertical posts (5b) are introduced at each extremity of the second horizontal rail (8) to a determined perforation number which coincides with the orifice selected on the first higher horizontal rail (7), so that the second horizontal rail slides on to the lowest extremities of the first and second vertical posts (3 and 4) that have a second diameter, until it reaches the steps (6) that is formed by the change of diameters in the middle part; each step (6) acts as a stop or brake for each horizontal rail that are temporarily assembled at the top and bottom ends of the vertical posts.

This request is intended as a temporary assembly, one that allows you to assemble and dismount the different elements of the arm-rest for a period of time, according to the needs and preferences of the user.

The first horizontal rail (7), represented with a top view in FIG. 5, presents at its centre two small slots (10a and 10b) parallel to its length, and the second horizontal rail (8) shown in FIG. 4, which presents at its centre one slot (10c), all of equal length. Through the slot 10c is put the belt (11) with a device at the opposite extremity to avoid it slipping out, and it slides between the first and second slots, so that the free end can attach itself firmly. Preferably the belt (11) has a type of retention such as Velcro®, hooks, buttons, just to mention a few examples, that permits the temporary retention between the horizontal rails when the support is assembled.

It is important to note that the sets of perforations located at the extremities of each horizontal rail, is composed of preferably 7 holes in each set.

The first horizontal rail has a length of at least 40 cm and a maximum of 100 cm and the second horizontal rail should have a minimum length of 30 cm and a maximum of 90 cm. Despite the difference in length between the first and second horizontal rails, that varies between 10% and 20% of the length between them, the perforations coincide, because they have an it inclination of 10° in relation to the centre and additionally the slots are aligned to the centre when the support is assembled.

And, the perforation number chosen is determined by the size of the arm-rest, so that if the first perforation is chosen for the assembly alignment (which is the hole closest to the centre, preferably 14 cm) the smallest size of arm-rest will be mounted and if last perforation is chosen (the furthest from the centre) the largest size of arm-rest will be mounted, so that according to the perforation chosen the arm-rest can be larger or smaller in length and therefore adaptable to multiple users regardless of their size.

As the horizontal rails support the weight of the arms, they have to be 1 cm thick n order to resist breaking under the weight.

However, considering that the support is manufactured from light materials such as plastic, aluminium, wood and must resist deformation with weight (to support the weight of the arms of the user) it is possible to define the ideal size of it in terms of length and cut off the surplus to maintain only the required size.

EXAMPLE OF THE PREFERRED MANUFACTURE

Below is described an example for manufacture of the proposed arm-rest, but it should be noted that the measurements and proportions mentioned are only illustrative.

The arm-rest in this example is made up of two vertical posts with a length of 38 cm each.

The middle part has a length of 22 cm and a diameter of 2.5 cm and the upper end a length of 8 cm, and another 8 cm at the lower end. The diameter of each of the extremities is 1.9 cm.

The first horizontal rail has a length of 69 cm and the second horizontal rail has 15% less length in relation to the first and therefore 59 cm. Both are 1 cm thick and width of 4.5 cm.

The first and second rails have a set of perforations at each end, with diameters of 1.9 cm, with a separation of 1 cm between each of them and on the second rail the first hole on each side is 10 cm from the centre whereas in the first rail it is 14 cm.

The second rail (8) has a the middle with 0.3 cm width and 3 cm long being parallel to its length.

The first rail has two identical slot with the same characteristics through which the Velcro belt, with 50 cm long and width of 2.5 cm, is inserted.

Characteristically, the assembly of the proposed arm-rest consists of:

    • a) To hold the second horizontal rail to the thighs of the seated user.
    • b) To determine the perforation that limits the lateral movement, according to the opening of the thighs.
    • c) To insert in each of the selected holes of the second horizontal rail the lower extremities of the vertical posts, coming to rest ort the small steps that define the middle part.
    • d) Insert the top ends of the vertical posts in the corresponding holes in the first horizontal rail, until they reach the small steps that define the middle part, and at this point the arm-rest is completely assembled, however it can be involuntarily dismounted, so it is recommended to complete subsection e).
    • e) Slide the Velcro belt into the third slot located in the first horizontal rail (7), making sure to fold the belt to avoid it slipping.
    • f) Insert the free end of the belt through one of the slots in the second horizontal rail (8) and pull it tight
    • g) Insert the free end of the belt through the remaining slot in in the second horizontal rail (8), in such a way that the belt is parallel to itself and can be secured using the Velcro®, so the arm-rest is prevented from being dismounted.

Finally, the arm-rest is assembled and ready for use.
