Abstract

The ladder includes two fixed uprights and steps fixed between each other mainly applicable to swimming pools. is characterised in that the uprights have diametrically opposed holes in an area on each step which attaches to a bushing on the upright formed by two halves with a lower peripheral step which is supported onto the step by an opening near to its ends. This coupling is fixed by a nut which is screwed onto the upper peripheral thread of the two halves forming a bushing which is supported on the step. The holes in the uprights consist of openings housing the respective lugs in the internal periphery of the bushing halves. The step comprises a base to which a base is attached, both of which are made from plastic.

ANTECEDENTES DA INVENÇÃOBACKGROUND OF THE INVENTION

De um modo geral, estes tipos de escadas têm degraus fixos aos montantes utilizando parafusos e porcas e, nalguns casos, utilizam-se casquilhos que são inseridos nos montantes e fixos a aberturas tubulares nos degraus.In general, these types of ladders have steps attached to the uprights using bolts and nuts and, in some cases, bushes are used which are inserted in the uprights and fixed to tubular openings in the steps.

SUMÁRIO DA INVENÇÃO 0 objectivo da invenção é obter uma escada de fácil montagem e desmontagem que possa ser comercializada como DIY, dado que pode ser montada pelo próprio utilizador ou qualquer outra pessoa sem qualificações. As peças componentes podem ser substituídas por outras quando necessário. A escada desmontada ocupa pouco espaço e, desse modo, pode ser facilmente armazenada e transportada. Além disso, esta escada tem um degrau com um formato que pode ser alterado à vontade do utilizador. 1SUMMARY OF THE INVENTION The object of the invention is to provide an easily assembled and dismantled ladder that can be marketed as DIY, since it can be assembled by the user himself or any other person without qualifications. Component parts can be replaced with other parts when necessary. The disassembled ladder takes up little space and thus can be easily stored and transported. In addition, this ladder has a step with a shape that can be changed at will of the user. 1

Esta escada é caracterizada pelo facto de os montantes terem furos diametralmente opostos numa área em que cada degrau se acopla a um casquilho, no montante, formado por duas metades com um ressalto periférico inferior que é suportado, no degrau, por uma abertura próxima das suas extremidades. Este acoplamento é fixo por uma porca que é enroscada na rosca periférica superior das duas metades constituintes de um casquilho que está suportado no degrau.This ladder is characterized in that the uprights have diametrically opposed holes in an area in which each step engages an upright bushing formed by two halves with a lower peripheral shoulder which is supported on the step by an opening close to its extremities. This coupling is fixed by a nut which is screwed onto the upper peripheral thread of the two constituent halves of a bushing which is supported on the step.

De modo a obter as diferentes concepções do degrau, há uma base que é acoplada a uma cobertura com uma concepção que permite a escolha a partir de diversas coberturas.In order to obtain the different designs of the step, there is a base which is coupled to a cover with a design that allows the choice from several covers.

DESCRIÇÃO DETALHADADETAILED DESCRIPTION

De acordo com os desenhos, a escada inclui dois montantes (1 e 2) tubulares metálicos e diversos degraus (3) em plástico.According to the drawings, the ladder includes two metal tubular uprights (1 and 2) and several plastic steps (3).

Os montantes (1 e 2) têm uma área (4) com aberturas (5 e 5') diametralmente opostas para cada degrau que se acopla a um casquilho, nos montantes, formado por duas metades (6 e 7) que tem um ressalto (8) periférico inferior no qual o degrau (3) é suportado por uma abertura (9) próxima das suas extremidades. Este acoplamento é fixo por uma porca (10) que se enrosca na periferia (11) roscada superior das duas metades dos casquilhos e que é suportada pelo degrau (3). As aberturas (5 e 5') alojam respectivas projecções (12) existentes na periferia interna das duas metades do casquilho.The uprights (1 and 2) have an area (4) with diametrically opposed openings (5 and 5 ') for each step which engages a bushing on the uprights, formed by two halves (6 and 7) having a shoulder ( 8) in which the step (3) is supported by an opening (9) proximate its ends. This coupling is fixed by a nut (10) which screws onto the upper threaded periphery (11) of the two halves of the bushes and which is supported by the step (3). The openings (5 and 5 ') house respective projections (12) on the inner periphery of the two bushing halves.

Os degraus (3) são formados por uma base (13) e uma cobertura (14) e a concepção do degrau pode ser alterada através da mudança da cobertura. 3The steps (3) are formed by a base (13) and a cover (14) and the design of the step can be changed by changing the cover. 3

As metades (6 e 7) dos casquilhos têm uma forma (15) cónica na sua periferia externa que facilita a sua entrada no degrau pela abertura (9) através do seu furo inferior.The bush halves 6 and 7 have a conical shape 15 at their outer periphery which facilitates their entry into the rung through the aperture 9 through their lower bore.

No furo acima mencionado e no furo superior da abertura, o degrau apresenta ressaltos (16 e 17) interiores que se encaixam, respectivamente, no ressalto (8) inferior das metades de casquilho e na porca (10). A porca (10) tem uma secção transversal em forma de L com um rebordo (18) superior interno que tem furos (19) para a introdução de uma ferramenta para facilitar o enroscamento e desenroscamento da porca nas roscas das duas metades do casquilho.In the aforementioned hole and in the upper hole of the aperture, the step has inner shoulders (16 and 17) which respectively engage the lower shoulder (8) of the sleeve halves and the nut (10). The nut 10 has an L-shaped cross-section with an upper inner collar 18 having holes 19 for introducing a tool to facilitate screwing and unscrewing of the nut on the threads of the two bushing halves.

Como é lógico, a cobertura (14) tem aberturas (9') coincidentes (9) na base (13) para a inserção do degrau nos montantes (1 e 2) .Of course, the cover 14 has matching apertures 9 'in the base 13 for insertion of the step in the uprights 1 and 2.

As Figuras 6 e 7 mostram a cobertura formada por duas peças sobrepostas, a peça (14a) superior é metálica e a parte (14b) inferior é em plástico. Estas peças, de acordo com a figura 7, têm aberturas (20) superiores com uma borda (21) semielástica ligeiramente elevada na parte inferior constituindo uma superfície superior antiderrapante.Figures 6 and 7 show the cover formed by two overlapping pieces, the upper piece (14a) is metallic and the bottom part (14b) is plastic. These parts, according to Figure 7, have upper openings (20) with a slightly raised semi-elastic border (21) in the lower part constituting a non-slip upper surface.

As peças (14b) inferiores têm um contorno (23) elástico em forma de U em torno das mesmas para alojar a borda periférica das peças (14a) metálicas. 4 A base (13) do degrau superior tem uma extensão (22) horizontal (figura 1) na sua borda posterior que irá ocupar a folga entre o degrau e a parede da piscina. corrimões escada, oThe lower pieces (14b) have a U-shaped elastic contour (23) around them for housing the peripheral edge of the metal pieces (14a). The base 13 of the top step has a horizontal extension 22 (Figure 1) at its rear edge which will occupy the gap between the step and the pool wall. stair railing, the

No caso de escadas seccionadas, nas quais os laterais são independentes dos montantes (1 e 2) da degrau superior é fixo por porcas cegas.In the case of sectioned ladders in which the sides are independent of the uprights (1 and 2) of the upper step is fixed by blind nuts.
