Traction bearing and rod joint from the sliding shelf set

Abstract

Traction bearing and rod joint to anchor a sliding shelf set to an oven door, the bearing (1) being made of engineering plastic, stainless steel or another compatible material, and is designed to be installed on the internal glass or surface of the counter door (P) of the stove (F1) by fitting into an orifice. The locking of the bearing (1) in this orifice is held by the provision of a beveled skirt (7) and a collar (6), both applied on the outer surface of the bearing (1). The tensile bearing has a longitudinal slot (2) and a channel (4) that communicate with each other to allow docking and rotation of the end (E) of a rod (H) of the set of shelves (PD) when the door (P) of the oven (F1) is opened or closed.

Claims

1. A traction bearing and rod joint to anchor a sliding shelf set to an oven door to act as an anchoring element for end rotation of a rod from the sliding shelf set; wherein the traction bearing is cylindrical and provided with central longitudinal slot, with thickness, beginning at a base of the bearing and extending until reaching a transversal channel, the transversal channel passing through a head of the bearing and having a diameter substantially equivalent to an external diameter of the end of the rod; wherein the longitudinal slot divides the bearing in two portions and flexible between them; wherein the base has a collar and a beveled skirt above the collar that is tapered such that a diameter at an upper portion of the beveled skirt is smaller than a diameter at a lower portion of the beveled skirt, the lower portion being located farther from the transversal channel than the upper portion; wherein a recessed space is located between the lower portion of the beveled skirt and the collar for housing an orifice edge of an orifice of the oven door; wherein the beveled skirt comprises a frustoconical surface that extends at least partially about a central axis of the traction bearing; and wherein the traction bearing is configured to be anchored to the oven door by inserting the head and the beveled skirt of traction bearing through the orifice; and wherein a diameter of the collar is substantially greater than the diameter at the lower portion of the beveled skirt.

2. The traction bearing according to claim 1 wherein the orifice (2) is made in internal glass (V) of the oven door of the oven (F1).

3. The traction bearing according to claim 1 wherein the orifice (2) is made in a counter-door (P) of the oven (F1).

4. The traction bearing according to claim 1 wherein since the longitudinal slot (2) is composed by two portions (1a) and (1b) flexible between them, the traction bearing (1) acts with a spring effect associated with the memory of the material of the bearing's manufacture.

5. The traction bearing according to claim 1 wherein the traction bearing (1) is made of engineering polymer.

6. The traction bearing according to claim 1 wherein traction bearing (1) is made of steel.

7. The traction bearing according to claim 1 wherein the end rotation (E) of the rod (H) occurs in the channel (4) of the traction bearing (1).

8. The traction bearing according to claim 1 wherein the traction bearing (1) is made in single part.

9. The traction bearing according to claim 1, wherein a cross-section of the transversal channel comprises a perimeter that is closed except where the longitudinal slot intersects the channel.

10. The traction bearing according to claim 1, wherein the channel defines a closed end of the slot.

11. The traction bearing according to claim 1, wherein the channel is spaced from the base.

12. The traction bearing according to claim 1, wherein the head (5) of the traction bearing (1) has a substantially cylindrical outer surface that is coaxial with the beveled skirt (7).

13. The traction bearing according to claim 1, wherein the collar (6) of the traction bearing (1) has a substantially cylindrical outer surface.

DETAILED DESCRIPTION OF THE INVENTION

(7) While the present invention may be susceptible to a different modality, it is shown in the drawings and in the following detailed discussion, a preferred modality of the invention with the understanding that the present description must be considered an exemplification of the principles of the invention, without no intention of being limited to what is illustrated and described herein.

(8) The tension bearing (1) belongs to the field of accessories for stoves (F), and other related items, and more particularly, it acts as anchoring element and rotation of the end (E) of the rod (H) of the set of sliding shelves (PD) of the type that is installed in ovens (F1) of stoves (F), including mobile-type, embedded, bench, and related ovens.

(9) According to the present invention, the tensile bearing (1) is preferably made in one piece, obtained preferably in engineering polymer, of the type Teflon®, Zytel®, Fortron®, special silicone and other, that is, with special characteristics, such as, for instance, resistance to high temperatures and may be also made from other materials, such as steel.

(10) This bearing (1) presents itself ordinarily cylindrical and provided with a central longitudinal slot (2) of a thickness (x), which starts at the base (3) of the bearing and extends to reach a transverse channel (4) located next to the head (5) of the bearing, whose channel has a diameter (d), which corresponds to the outer diameter of the end (E) of the rod (H). The longitudinal slot (2) divides the bearing into two portions (1a) and (1b) flexible between each other, acting with spring effect associated with the memory of the manufacture material of the bearing.

(11) The base (3) has outer peripheral collar (6), and just above it, a beveled skirt (7) is provided, which sets, between the widened base (7a) of this and the collar (6), a recessed space (8) for housing of the edge of the orifice (O2), preferably practiced on the inner glass (V) of the oven (F1), at the time of the assembly of the tensile bearing (1) in the stove. In an alternative embodiment, the orifice (O2) can be practiced directly on the counter door (P).

(12) Since the preferred embodiment is the attachment on the inner glass, it is highlighted that the consumer himself can easily remove the tensile bearing described, since cooking ovens are provided in the state of the art, with removable inner glass, thus, facilitating cleaning the oven and components parts, in addition to facilitating, when necessary, the replacement of the part. Thus, to fit the tensile bearing (1) in the hole (O2) of the inner glass or counter door, just bend the portions (1a) and (1b) in order to bring them together, allowing the bearing to pass through said hole whose inner edge is positioned in the space (8). When releasing the parts (1a) and (1b), they, due to the flexibility of the material, return to a resting position, turning the orifice (O2) stable between the skirt (7) and the collar (6), consequently allowing that the channel (4) houses the end (E) of the rod (H), allowing its rotation at the time of the opening and closing of the door (P) of the oven (F1).

(13) It is true that when the present invention is put into practice, other related shapes can be made, not being restricted to the examples mentioned above. Changes relative to certain details of construction, shape and material can be practiced without implying moving away from the fundamental principles that are clearly substantiated on the set of claims, being thus understood that the terminology employed had the purpose not to limit it.
