Abstract
An armrest includes an armrest body, a veneer layer, and a pair of elongate decorative ribs. The armrest body is made of a wood material different from oak wood, extends in a longitudinal direction, and has lower, upper and opposing lateral surfaces. Each of the lateral surfaces is formed with a groove, planar and curved surface sections. The veneer layer is made of oak wood, and includes upper and lower veneer portions. The upper and lower veneer portions are fixedly attached to and cover the upper and lateral surfaces of the armrest body. Each of the decorative ribs is made of oak wood, extends in the longitudinal direction, and has a mounting section fixed in one of the grooves, and a protruding section protruding from the veneer layer.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an armrest, more particularly to an armrest that has upper and lateral surfaces wholly covered by oak wood.
2. Description of the Related Art
Referring to
FIG. 1
, a conventional armrest
1
is shown to comprise an armrest body
10
that extends in a longitudinal direction, and that is formed with a lower surface
101
, an upper surface
102
, and opposing lateral surfaces
103
that interconnect the lower and upper surfaces
101
,
102
. Each of the lateral surfaces
103
is formed with a protruding rib
104
that extends in the longitudinal direction, a planar surface section
105
that extends from the lower surface
101
to a lower edge
104
′ of the rib
104
, and a curved surface section
106
that extends from an upper edge
104
″ of the rib
104
to the upper surface
102
.
The wood material commonly used for the conventional armrest
1
is oak wood because oak wood has high density, is tough and durable, and has uniform grain. However, the processing of the conventional armrest
1
using the multi-faceted wood planing machine results in a severe wastage of oak wood material.
Referring to
FIG. 2
, an armrest
2
with an oak veneer layer has been proposed heretofore to overcome the aforesaid drawback. The armrest
2
comprises an armrest body
20
that extends in a longitudinal direction, and a veneer layer
30
. The armrest body
20
is made of a wood material different from oak wood, such as pine wood, red wood, and cedar wood, and has a lower surface
201
, an upper surface
202
, and opposing lateral surfaces
203
that interconnect the lower and upper surfaces
201
,
202
. Each of the lateral surfaces
203
is formed with a protruding rib
204
that extends in the longitudinal direction, a planar surface section
205
that extends from the lower surface
201
to a lower edge
204
′ of the rib
204
, and a curved surface section
206
that extends from an upper edge
204
″ of the rib
204
to the upper surface
202
. The veneer layer
30
is made of oak wood, and is fixedly attached to and covers the upper surface
202
and the curved surface sections
206
of the lateral surfaces
203
of the armrest body
20
.
The armrest
2
has a relatively low oak wood material requirement. However, the planar surface sections
205
of the lateral surfaces
206
of the armrest body
20
are unable to be covered by the veneer layer
30
because of the protruding ribs
204
.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide an armrest that has upper and lateral surfaces wholly covered by oak wood.
Accordingly, an armrest of this invention comprises an armrest body, a veneer layer, and a pair of elongate decorative ribs. The armrest body is made of a wood material different from oak wood, extends in a longitudinal direction, and has a lower surface, an upper surface and opposing lateral surfaces that interconnect the lower and upper surfaces. Each of the lateral surfaces is formed with a groove that extends in the longitudinal direction and that has lower and upper groove edges, a planar surface section that extends from the lower surface to the lower groove edge, and a curved surface section that extends from the upper groove edge to the upper surface. The veneer layer is made of oak wood, and includes an upper veneer portion and a pair of lower veneer portions. The upper veneer portion is fixedly attached to and covers the upper surface and the curved surface sections of the lateral surfaces of the armrest body. The lower veneer portions are fixedly attached to and cover respectively the planar surface sections of the lateral surfaces of the armrest body. Each of the elongate ribs is made of oak wood, extends in the longitudinal direction, and has mounting and protruding sections. The mounting section is fixed in the groove of a respective one of the lateral surfaces of the armrest body. The protruding section is connected to the mounting section and protrudes from the veneer layer.

in accordance with the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 3 and 4
, the first preferred embodiment of an armrest
4
according to the present invention is shown to comprise an armrest body
41
, a veneer layer
42
, and a pair of elongate decorative ribs
43
. The armrest body
41
is made of a wood material different from oak wood, such as pine wood, red wood, cedar wood and rubber wood, extends in a longitudinal direction, and has a lower surface
401
, an upper surface
402
and opposing lateral surfaces
403
that interconnect the lower and upper surfaces
401
,
402
. Each of the lateral surfaces
403
is formed with a groove
44
that extends in the longitudinal direction and that has lower and upper groove edges
441
,
442
, a planar surface section
404
that extends from the lower surface
401
to the lower groove edge
441
, and a curved surface section
405
that extends from the upper groove edge
442
to the upper surface
402
.
The veneer layer
42
is made of oak wood, and includes an upper veneer portion
422
and a pair of lower veneer portions
421
. The upper veneer portion
422
is fixedly attached to and covers the upper surface
402
and the curved surface sections
405
of the lateral surfaces
403
of the armrest body
41
. The lower veneer portions
421
are fixedly attached to and cover respectively the planar surface sections
404
of the lateral surfaces
403
of the armrest body
41
.
Each of the decorative ribs
43
is made of oak wood, extends in the longitudinal direction, and has mounting and protruding sections
431
,
432
. The mounting section
431
is fixed in the groove
44
of a respective one of the lateral surfaces
403
of the armrest body
41
by means of an adhesive. The protruding section
432
is connected to the mounting section
431
and protrudes from the veneer layer
42
.
The upper and lateral surfaces of the armrest
4
according to this invention are wholly covered by oak wood.
Preferably, the wood material for the armrest
4
is rubber wood, which is readily available and is relatively inexpensive. In addition, each of the decorative ribs
43
has a teardrop cross-section and tapers in a direction from the protruding section
432
to the mounting section
431
.
The process for producing the armrest
4
of the present invention is best illustrated with reference to
FIGS. 5
to
7
. In
FIG. 5
, the armrest body
41
is contoured without forming the grooves
44
. Then, as shown in
FIG. 6
, the veneer layer
42
is fixedly attached to and covers the upper and lateral surfaces
402
,
403
of the armrest body
41
. Subsequently, as shown in
FIG. 7
, the grooves
44
are cut in the veneer layer
42
and in the lateral surfaces
403
of the armrest body
41
with the use of a lathe machine, thereby forming the planar and curved surface sections
404
,
405
on the lateral surfaces
403
, and the upper and lower veneer portions
422
,
421
of the veneer layer
42
. Finally, as shown in
FIG. 4
, the decorative ribs
43
are bonded adhesively in the grooves
44
of the lateral surfaces
403
of the armrest body
41
.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
