Description

TELESCOPIC LINEAR GUIDE Technical field
[0001] The present invention generally relates to a telescopic linear guide. The invention further relates to an assembly comprising such a telescopic linear guide. Background art
[0002] Telescopic linear guides are known in the art. EP2741633 B1 describes a telescopic linear guide, comprising two guide rails which are displaceable relative to one another by means of rolling elements. The disadvantage of this type of telescopic linear guide is that it is complex, expensive, fragile and limited in its load bearing capacity.
Summary of the invention
[0003] It is an object of the invention to provide a telescopic linear guide that solves the disadvantages of the prior art e.g. that it is simpler, less expensive, easier to assemble, robust and less sensitive to dirt. Embodiments according to the invention preferably solve one or even more preferably all of the disadvantages associated with solutions according to the prior art.
[0004] According to a first aspect of the invention the object is achieved by providing a telescopic linear guide according to the appended claims. The telescopic guide comprises a first linear bearing suitable for being fixedly connected to a support and a first rod-like member movably connected to the first linear bearing. Furthermore, the first rod-like member is configured to be guided by the first linear bearing. The telescopic linear guide further comprises a second rod-like member fixedly connected to the first rod-like member and arranged in parallel to the first rod-like member. Additionally, the telescopic linear guide may comprise a second linear bearing suitable for being fixedly connected to a moveable body, which second linear bearing is movably connected to the second rod-like member and configured to be guided by the second rod-like member. Such a telescopic linear guide achieves the object of the invention because it comprises less parts and the parts used are easier to assemble. Furthermore, rod-like members are robust. Additionally, such a telescopic linear guide has an improved load bearing capacity.
[0005] Preferably, the first and the second rod-like member substantially overlap to reduce the size of the telescopic linear guide in a retracted state for a telescopic linear guide having a given reach.
[0006] In a preferred embodiment, the telescopic linear guide comprises at least one other first linear bearing movably connected to the first rod like member and suitable for being fixedly connected to a support, wherein the first rod-like member is configured to be guided by the at least one other first linear bearing. This may reduce the stress on the first linear bearing and/or the first rod-like member. Likewise, for the second rod-like member and/or the second linear bearing it is advantageous when the telescopic linear guide comprises at least one other second linear bearing suitable for being fixedly connected to the body, wherein the at least one other second linear bearing is movably connected to the second rod-like member and configured to be guided by the second rod-like member.
[0007] Typically, the first and the second rod-like member of a telescopic linear guide according to the present invention each comprise a first end and a second end opposite to the first end. Preferably, a first direction defined by the second end in relation to the first end of the first rod-like member is substantially the same as a second direction defined by the second end in relation to the first end of the second rod-like member. The first and second rod-like members may be arranged such that their first ends and their second ends are respectively located at corresponding positions, preferably wherein the first and the second rod-like member essentially have a same length. The first end of the first rod-like member is fixedly connected to the first end of the second rod-like member. To that end, the telescopic linear guide may comprise afirst connecting member, wherein the first connecting member connects the first ends of the first and the second rod-like member. Such first and second rod-like member may essentially be made from a single rod-like member comprising a curved section and two straight sections at opposing ends of the curved section, wherein the connecting member comprises the curved section and the first and second rod-like member comprise one and another one of the two straight sections.
Alternatively, the first connecting member may comprise an end plate configured for being attached to the first end of the first rod-like member and to the first end of the second rod-like member.
[0008] Additionally, the second end of the first rod-like member may be fixedly connected to the second end of the second rod-like member. To that end, the telescopic linear guide may comprise a second connecting member, such as an end plate, wherein the second connecting member connects the second ends of the first and the second rod-like member. The second connecting member may be a same or a different type of connecting member as the first connecting member. Alternatively, the first and second rod-like member and the first and second connecting member are made from a single piece of (e.g. casted and/or milled) material.
[0009] Each one of the first linear bearings may advantageously be arranged between the first and the second end of the first rod-like member. Furthermore, each one of the second linear bearings may advantageously be arranged between the first and the second end of the second rod-like member. Preferably, at least one, advantageously all of the linear bearings comprise a sliding surface configured for sliding along the corresponding rod-like member, such as a linear slide bearing. The benefit of using linear slide bearings (e.g. bushings) is that they are less sensitive to dirt. For instance, in case dirt is deposited on the rod-like members, the sliding action of the rod-like members along the linear slide bearing provides a cleansing action. Furthermore, the linear slide bearings are preferably free from any rolling elements.
[0010] For an increased reach, instead of elongating the first and second rod-like elements, the telescopic linear guide may comprise at least one further set of linear bearings and rod-like elements according to any of the embodiments as described before. Such a telescopic linear guide may for instance comprise a third linear bearing connected (e.g. fixedly) to the second linear bearing, a third rod-like member movably connected to the third linear bearing, wherein the third rod-like member is configured to be guided by the third linear bearing, a fourth rod-like member fixedly connected to the third rod-like member and arranged in parallel to the third rod- like member, a fourth linear bearing suitable for being fixedly connected to a body, wherein the fourth linear bearing is movably connected to the fourth rod-like member and configured to be guided by the fourth rod-like member.
[0011] The first and the second rod-like members, as well as the third and fourth rod-like members can have any suitable cross-section, such as circular, elliptical or polygonal.
[0012] The invention further relates to an assembly comprising at least one, preferably two telescopic linear guides according to the appended claims. The assembly further comprising a support, for instance provided by a housing, and a body, for instance a platform or container (e.g. drawer), connected to the support by the at least one preferably two telescopic linear guides and configured for moving relative to the support. In case the assembly comprises afirst and a second telescopic linear guide, it is preferred that the telescopic linear guides are connected to opposing sides of the body for improved stability. Brief description of the figures
[0013] Aspects of the invention will now be described in more detail with reference to the appended drawings, wherein same reference numerals illustrate same features.
[0014] Figs. 1A-B show side views of a schematic representation of a telescopic linear guide according to the present invention in two states.
[0015] Figs. 2A-B shows top views of a schematic representation of an assembly comprising the telescopic linear guides of Figs. 1A-B in two states. Detailed description of embodiments
[00186] The invention will be further explained according to the figures, wherein the same numerals refer to the same features.
[0017] Referring to Figs. 1A-B, a telescopic linear guide 10 may comprise a first straight rod-like member 12 substantially in parallel to a second rod-like member 13. The first and second rod-like members 12, 13 may substantially overlap one another along a longitudinal direction. The first and second rod-like members 12, 13 may further be fixedly connected to each other at either end of the rod-like members, for instance by means of a connecting member 17 at one end and another connecting member 18 at another end.
[0018] The first rod-like member 12 may be connected to one, preferably two first linear bearings 11, (each) configured for being attached to a support and for moving along the first rod-like element 12. In a first state (see Fig. 1A), a second end of the first rod-like member 12 is located in close proximity to {one of) the first linear bearing(s) 11 and in a second state (see Fig. 1B) a first end of the first rod-like member 12 is located in close proximity to (another one of) the first linear bearing(s) 11.
[0019] The second rod-like member 13 may be connected to one, preferably two second linear bearings 14, (each) configured for being attached to a body and for moving along the first rod-like element 12. In a first state (see Fig. 1A), a first end of the second rod-like member 13 is located in close proximity to (one of) the second linear bearing(s) 14 and in a second state (see Fig. 1B) a second end of the second rod-like member 13 is located in close proximity to {another one of) the second linear bearing(s) 14.
[0020] Referring to Figs. 2A-B, an assembly 30 according to the present invention may comprise two telescopic linear guides 20 advantageously connected to opposing edges of the body 16. Preferably, the telescopic linear guides 20 comprise at least one, preferably two first linear bearings 11 configured for being connected to the support 15 and a first rod-like member 12 connected to the first linear bearings 11 and configured for moving along the first linear bearings 11. Furthermore, it may comprise a second rod-like member 13 connected to the first rod-like member 12 and arranged in parallel to the first rod-like member 12. The second rod-like member 13 may be connected to the platform 18 through at least one, preferably two second linear bearings 19 configured for moving along the second rod like member 13.
[0021] Referring to Fig. 2A, in a first state a second end of the first rod-like member 12 is located in close proximity to (one of) the first linear bearing(s) 11. For instance, the second connecting member 18 abuts one end of (one of) the first linear bearing(s) 11. Furthermore, a first end of the second rod-like member 13, connected to the opposing first end of the first rod-like member 12, is located in close proximity to (one of) the second linear bearing(s) 19. For instance, the first connecting member 17 abuts one end of (one of} the second linear bearing(s) 19.
[0022] Referring to Fig. 2B, in a second state a first end of the first rod-like member 12 is located in close proximity to (one of) the first linear bearing(s) 11. For instance, the first connecting member 17 abuts one other end of (one of) the first linear bearing(s) 11. Furthermore, a second end of the second rod-like member 13, connected to the opposing second end of the first rod-like member 12, is located in close proximity to (one of) the second linear bearing(s) 19.
For instance, the second connecting member 18 abuts one other end of (one of) the second linear bearing(s) 19.

These linear slide bearings are advantageously configured for enclosing the corresponding rod-like member over at least part of a cross sectional circumference, preferably for completely enclosing a cross section of the corresponding rod-like member. By way of 5 example, the linear slide bearings can be formed as bushings or sleeves comprising a hole, wherein the corresponding rod-like member moves through the hole. Linear slide bearings have the advantage that they automatically remove any dirt or debris from the corresponding rod-like member, making them ideally suitable for outdoor applications, or for applications in dusty or heavy polluted environments.
[0024] Alternatively, the linear bearings can be linear rolling-element bearings, such as ball bearings.
